Definitions
- the present invention relates to a temperature control system used in a kneading extrusion molding apparatus for kneading chemical materials such as stone chips, which are raw materials of stone chips, various oils and fats, and extruding them into a predetermined shape, and a kneading extrusion device equipped with the same. It relates to a molding device. [Background technology]
- the effect of suppressing the temperature rise of the material to be processed which is conveyed and kneaded is certainly recognized as compared with the case where the device is not used.
- the portion of the object to be kneaded and conveyed that comes into contact with the inner peripheral surface of the cylinder is cooled, and the center of the extrusion screw in the object to be treated is cooled.
- the parts that are kneaded and conveyed in the vicinity are not directly cooled by this cooling water. Therefore, the material to be processed that is transported and kneaded in the portion near the center of the cylinder is cooled by contact with the inner wall of the cylinder during the process of being transported.
- the object to be conveyed when the object to be conveyed is observed along the cross section of the cylinder, the object to be treated in the vicinity of the inner peripheral surface of the cylinder is maintained at a relatively low temperature under the influence of the cooling water.
- the object to be processed in the vicinity of the reuse remains in a high temperature state, and a phenomenon occurs in which the temperature of the object to be processed in the cylinder varies depending on its position in the radial direction, causing variations in the quality of the final product. rice field.
- an object of the present invention is to provide a method for treating an object to be treated such as a stone substrate at a predetermined low temperature or high temperature in a cylinder at a predetermined position in the axial direction of the cylinder.
- an object to be treated such as a stone substrate at a predetermined low temperature or high temperature in a cylinder at a predetermined position in the axial direction of the cylinder.
- the temperature control system of the present invention is characterized by: a fixed disk having a flow channel extending from the vicinity of the central portion to the vicinity of the peripheral portion;
- a fluid supply means connected to the channel inlet and the channel outlet and circulatingly supplying a fluid
- a temperature control means for controlling the temperature of the fixed disk is provided, and the fixed disk penetrates in the thickness direction of the plate surface and is in communication with the flow path. The point is that it has a plurality of holes that are not
- the characteristic configuration of the kneading extrusion molding apparatus using the above temperature control system includes a receiving tank for receiving the material to be processed, a cylinder containing a screw for extruding and conveying the material to be processed, and this cylinder
- a kneading extrusion molding device comprising a kneading mechanism for kneading the material to be processed and a molding mechanism for molding the kneaded material to be processed,
- the kneading mechanism is composed of a rotary disc that rotates integrally with the screw, and a fixed disc and the cam that are fixed to the cylinder and arranged side by side in the axial direction of the screw.
- the fixed disk contains a flow path near the center and near the periphery, and has an inlet and an outlet of the flow path,
- the present invention is characterized in that it has a temperature control system including a fluid supply means connected to the flow channel inlet and the flow channel outlet to circulately supply a fluid, and a temperature control means for controlling the temperature of the fixed disk.
- the object to be processed is compressed, shredded, and sheared when passing through the kneading mechanism having the rotating disk and the fixed disk.
- the temperature rise at this point is most pronounced, but the temperature control system of the present invention makes it possible to set the temperature of the fixed disk to a desired value. That is, when the object to be processed passes through the plurality of holes of the fixed disk and is pushed out, the temperature difference between the fixed disk and the object to be processed passing through the fixed disk causes the temperature difference from the inner periphery of the cylinder. Heat exchange occurs throughout the core, allowing temperature control to be very efficient compared to prior art devices.
- heat exchange between the object to be processed and the fixed disk is performed when the object to be processed contacts the inner peripheral surface of the plurality of holes of the fixed disk. Regardless of whether the object to be processed is located near the outer circumference of the fixed disk or near the inner circumference, heat exchange is carried out substantially uniformly. Substantial heat exchange is only performed on the material to be processed that is conveyed near the inner periphery, and heat is not exchanged on the material to be processed that is conveyed in the vicinity of the screw. Problems such as this have been resolved.
- the fixed disk is provided with a plurality of holes. Heat exchange occurs when passing through each inner peripheral surface. That is, the sum of the surface area of the fixed disc and the surface area of the inner peripheral surface of the plurality of holes is calculated, and the heat-conducting surface area of the conventional cooling channel is calculated as (per unit length in the axial direction of the cylinder)
- the former can be set to a larger value by increasing the number of holes in the fixing member.
- the surface area of the object to be treated that can be heat-exchanged by heat conduction is increased compared to conventional devices, and more efficient heat exchange can be performed.
- the temperature control system is configured by providing the flow path and the temperature control means inherent in the fixed disk, so that manufacturing is possible by improving the existing kneading mechanism. This makes it possible to simplify the equipment and reduce the cost of the entire device compared to the structure of the conventional technology in which a water channel is provided on the outer circumference of the cylinder.
- the temperature control system can also be used in combination with a cylinder outer peripheral portion temperature control device having a water channel filled with a fluid in the outer peripheral portion of the cylinder. According to this configuration, it is possible to synergistically obtain the effect of heat exchange obtained by the conventional temperature control device and the effect of the temperature control device of the present invention, and it is possible to provide a more effective temperature control system. becomes. As a result, the processing temperature of the object to be processed is maintained within a predetermined range, and the workability of the object to be processed and the quality of the final product are improved.
- the temperature control means includes a temperature sensor for measuring the temperature of the fixed disk, a temperature setting section for setting the temperature of the fixed disk, a measured temperature sensed by the temperature sensor, and the temperature setting section. It is also possible to have a comparison section that compares the temperature set by and a fingering section that adjusts the flow rate of the pump based on the temperature difference compared by the comparison section. With this configuration, the temperature of the fixed disk is set to a predetermined temperature, Varying the flow velocity of the fluid circulating in the flow path provided in the fixed disk so that the actual temperature of the fixed disk becomes equal to the set temperature by comparing with the actual temperature of the fixed disk. is possible, and automatic control of the temperature of the fixed disk can be easily implemented.
