However, in some ceramic production processes, the clay raw materials used are cylindrical in shape, and cylindrical clay raw materials are more convenient to store. If the above-mentioned device is used to extrude cylindrical clay, the screw rod inside will break the overall shape of the clay and crush it into multiple separate loose structures, which is not conducive to subsequent processing.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1-Figure 3 A ceramic extrusion mechanism includes a forming box 1 and a hoisting device 5. A water filter cartridge 2 is provided in the forming box 1. After mixing the ceramic solid raw material with the liquid, impurities therein are filtered out, and then the mixture is extruded into a block of clay. The mixed raw material is sent into the water filter cartridge 2, and the excess liquid therein is discharged to form a cylindrical clay. The above-mentioned clay is sent to the ceramic embryo workshop as the ceramic raw material for embryo pulling.

[0031] Furthermore, a plurality of water filtering holes 201 are provided in the water filter cartridge 2. The water filtering holes 201 penetrate the outer wall of the water filter cartridge 2, and the aperture of the inner cavity of the water filtering holes 201 is smaller than the aperture of the outer wall of the water filter cartridge 2. The inner size of the water filtering holes 201 is small, so when the mixed liquid raw material is squeezed, it is not easy to enter the water filtering holes 201. When squeezing out the cylindrical clay, it will not be hindered by the water filtering holes 201, which is more labor-saving.

[0032] Specifically, a water filter bag 3 is attached to the inner wall of the water filter cartridge 2, and each part of the water filter bag 3 is attached to the water filter cartridge 2. When the clay is squeezed, the water inside it flows out, but the clay is not easily squeezed out from the holes in the water filter bag 3. The water filter bag 3 is made of permeable material, and the mixed ceramic solution is introduced into the inside of the water filter bag 3. The top of the water filter bag 3 is inserted into the mounting plate 4, and the lower end surface of the mounting plate 4 is against the upper end surface of the molding box body 1.

[0033] Furthermore, the hoisting device 5 is connected to the pressure support 6. The hoisting device 5 is a crane in a ceramic clay workshop (used to produce cylindrical clay). The crane can be moved in the production workshop and can drive the pressure support 6 to move up and down. A guide cylinder 7 is installed at the bottom of the pressure support 6. A guide ring is installed at the lower end of the guide cylinder 7. The guide ring cooperates with the mounting plate 4. When the guide cylinder 7 falls on the molding box body 1, the guide ring is sleeved with the mounting plate 4, so that the pressure support 6 and the molding box body 1 remain relatively stable, so that the pressure support 6 can remain stable during the molding process of the cylindrical clay.

[0034] Specifically, a pressure plate 8 is provided in the pressure bracket 6, and the pressure plate 8 is connected to the first lifting mechanism 9, and the first lifting mechanism 9 is connected to the pressure bracket 6. The first lifting mechanism 9 can drive the pressure plate 8 to move up and down, and send the mixed raw materials into the water filter cartridge 2 and the water filter bag 3. After that, the first lifting mechanism 9 drives the pressure plate 8 to move down slowly, speeding up the discharge of excess liquid in the raw material, so that the clay can be quickly converted into a cylindrical solid shape. A feeding cavity 801 is provided in the pressure plate 8, and the feeding cavity 801 is connected to the feeding pipe 10. The other end of the feeding pipe 10 is connected to the storage box 11. The storage box 11 is used to store the mixed liquid raw material. The liquid raw material is connected to the feeding cavity 801 via the feeding pipe 10. It should be noted that the feeding pipe 10 is connected to a power pump for driving the flow of the liquid raw material;

[0035] More specifically, a lifting block 803 is inserted into the feed cavity 801. The lifting block 803 has two working states, namely a feeding state and a pressurizing state. In the feeding state, the feed cavity 801 is connected to the cavity inside the water filter cartridge 2. In the pressurizing state, the lower end surface of the lifting block 803 is flush with the lower end surface of the pressure plate 8. In this way, when the pressure plate 8 is pressed down, all parts are flush, and the same force can be applied to all parts in the water filter cartridge 2. The upper end surface of the clay finally formed is neat, and the clay is subjected to force at all locations at the same time. The compression degree of each position of the formed clay is roughly the same, and the water content of each part is roughly the same.

[0036] It should be noted that the lifting block 803 is connected to the spring 802. Without interference from other forces, the lifting block 803 can maintain balance under the action of the spring 802 and its own gravity. Figure 3 As shown in the position, the lifting block 803 includes an upper circular plate, a round rod, and a lower circular plate. The upper circular plate and the lower circular plate are connected by the round rod. Two parallel locking plates are inserted in the feeding cavity 801. The minimum distance between the two locking plates is equal to the thickness of the upper circular plate. Figure 2As shown, when the lifting block 803 is in the pressurized state, the upper circular plate therein is located between the two locking plates, and the locking plates are connected to the telescopic rod 804. The telescopic rod 804 is used to control the depth of the locking plate inserted into the pressurized plate 8. When the locking plate is withdrawn from the feed cavity 801, the power pump is started at this time to feed the liquid raw material into the feed cavity 801. The liquid raw material squeezes the lifting block 803 and moves it downward. At this time, the feed cavity 801 is connected to the cavity inside the water filter cartridge 2. The lifting block 803 is in the feeding state. The lifting block 803 A sealing groove is provided at the position of the upper circular plate, and a sealing ring is installed in the sealing groove. The sealing ring is used to play a sealing and isolation role to prevent the liquid raw material from entering the upper area of ​​the upper circular plate through the gap between the upper circular plate and the feeding cavity 801 and contacting the spring 802. If the above two are in contact, the surface of the spring 802 will adhere to and solidify clay, causing its elastic force to be affected, which will cause the height of the lifting block 803 to change when it is not affected by other external forces, and the locking block connected to the telescopic rod 804 cannot lock the position of the lifting block 803.

[0037] Furthermore, the water filter cartridge 2 is plugged with an extrusion rod, which is connected to the lower bottom plate 12, and the lower bottom plate 12 is fitted with the inner wall of the water filter bag 3. The extrusion rod is connected to the second lifting mechanism 13 for driving it to move up and down. A spray bottom plate is provided on the extrusion rod, and the spray bottom plate is connected to the spray mechanism 14. The drain port of the spray mechanism 14 faces the water filter bag 3, and the spray mechanism 14 is connected to the water tank, and a drainage hole 202 is provided at the bottom of the water filter cartridge 2. After the clay is extruded, the lower bottom plate 12 moves up under the drive of the second lifting mechanism 13 to squeeze the clay out of the water filter cartridge 2 and the water filter bag 3, which facilitates the unloading of the clay. The drainage hole 202 provided at the bottom can discharge the residual liquid in the water filter cartridge 2. At the same time, when the spray mechanism 14 sprays out clean water, the remaining liquid raw materials in the water filter cartridge 2 can be discharged, and the sewage enters the bottom of the molding box body 1 for subsequent unified treatment.

[0038] Working principle:

[0039] The pressurizing bracket 6 is moved into the forming box body 1 by the lifting equipment 5, and then the telescopic rod 804 is started to pull the locking plate out of the feeding cavity 801. At this time, the lifting block 803 moves up and down without being hindered by the locking plate, and the power pump is turned on to allow the liquid raw material to enter the feeding cavity 801 from the feeding pipe 10. The liquid raw material squeezes the lifting block 803, allowing it to move downward, and the liquid raw material enters the water filter bag 3 and the water filter cartridge 2. The lifting block 803 is in the feeding state at this time. After the liquid raw material is loaded, the power pump is turned off, and the lifting block 803 returns to its original position under the elastic force of the spring 802. Then the telescopic rod 804 drives the locking plate to move, locking the position of the lifting block 803. At this time, the lifting block 803 is flush with the lower end surface of the pressure plate 8, and it is in the pressurized state;

[0040] Start the first lifting mechanism 9 and let it drive the pressure plate 8 to move slowly downward, squeeze the liquid raw material, squeeze out the excess liquid inside, let the clay solidify, and finally the clay becomes cylindrical. Then the lifting equipment 5 removes the pressure bracket 6, and then the cylindrical clay is squeezed out of the water filter cartridge 2 by the second lifting mechanism 13. Use other equipment or manpower to remove the cylindrical clay.
