Technical Field
[0001] The invention relates to the technical field of insulator production, in particular to a mud refiner for insulator production. Background Art
[0002] A clay kneading machine is a key process equipment used for mixing clay in the ceramic manufacturing industry. It mainly achieves uniform mixing and refining of clay through mechanical action. The main function of a clay kneading machine is to allow the gas in the blank to escape and the moisture to be uniform, thereby improving its plasticity. A vacuum clay kneading machine is a type of clay kneading machine that removes gas from the clay through a vacuum environment, improves the physical properties of the clay, and thus improves the molding quality and consistency of the product.

DETAILED DESCRIPTION
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.
[0023] Reference Figures 1 to 7A mud refiner for insulator production includes a feed barrel 10, a vacuum box 2, a mud discharge barrel 3, a sieve plate 4 and a spiral pushing device. The feed barrel 10 is provided with a feed funnel 101, the vacuum box 2 is provided with an outlet pipe 201 connected to an external air extraction device, and the spiral pushing device is used to transport the mud in the vacuum box 2 and the mud discharge barrel 3 out. The feed barrel 10 is provided with a first chute 102, a first outlet 103, a placement groove 104 and a long groove 105. The placement groove 104 is communicated with the first outlet 103 and the long groove 105 respectively. The vacuum box 2 is provided with a second outlet 202 communicated with the first outlet 103. The sieve plate 4 is arranged in the first outlet 103; it also includes:
[0024] A pushing device, comprising a push plate 5, a buffer device and a first driving device, wherein the buffer device is connected to the push plate 5 and the first driving device, and the first driving device is used to drive the buffer device to move and drive the push plate 5 to slide in the first chute 102 and the first outlet 103;
[0025] The impurity discharge device includes a receiving plate 6, a second driving device and a cleaning device. The second driving device is used to drive the receiving plate 6 to move up and down in the placement groove 104. When there are particulate impurities on the receiving plate 6, the cleaning device works to clean the particulate impurities on the receiving plate 6. In the present invention, the mud material is put into the feeding barrel 10 from the feeding funnel 101, and the external exhaust device works to vacuum the vacuum box 2. The first driving device works to drive the push plate 5 to move to the right from the first slide groove 102 to the first outlet 103. At the same time, the second driving device drives the receiving plate 6 to move upward in the placement groove 104. The top of the receiving plate 6 is flush with the lower inner wall of the first outlet 103. The push plate 5 pushes a part of the mud material into the first outlet 103 and pushes it from the sieve plate 4 into the vacuum box 2. After the mud material falls into the vacuum box 2, the bubbles in the mud material expand and burst due to the pressure difference between the inside and the outside, and the residual air is extracted. The degassed mud material is squeezed by the spiral pushing device in the mud discharge tube 3 and discharged from the machine head and mold at one end of the mud discharge tube 3 to form a billet. When there are large particles of solid impurities (such as stone particles) in the mud material, they cannot pass through the mesh holes on the sieve plate 4 and are intercepted on the receiving plate 6. The second driving device drives the receiving plate 6 to move downward in the placement groove 104, and the cleaning device works to clean the large particles of solid impurities on the receiving plate 6 to prevent the push plate 5 from squeezing the large particles of solid impurities and then squeezing the sieve plate 4 to cause deformation when the push plate 5 moves to the right again and contacts the sieve plate 4. It can also reduce the large particles of solid impurities being squeezed into the mesh holes of the sieve plate 4 to cause blockage. Specifically, the spiral pushing device includes a second motor 23, a reducer 24 and a continuous spiral auger 25. The second motor 23 drives the continuous spiral auger 25 in the mud discharge tube 3 to rotate through the reducer 24 to push the mud out; specifically, it also includes a column 26 and a bottom plate 27. One end of the feed tube 10 is embedded in the column 26, and the push plate 5 passes through the column 26. The support seat 11, the column 26, the vacuum box 2 and the spiral pushing device are all arranged on the bottom plate 27.
[0026] As a preferred embodiment of the present invention, it may also have the following additional technical features:
[0027] In this embodiment, a second slide groove 501 is provided on the push plate 5; the buffer device includes a T-shaped push rod 7, a first spring 8 and a first pull rope 9, the push rod 7 is arranged on the first driving device and one end thereof can slide in the second slide groove 501, the first spring 8 is arranged in the second slide groove 501, and the first pull rope 9 connects one end of the push rod 7 and the wall of the second slide groove 501. When the push plate 5 moves to the right to push the mud material, when there are large particles of solid impurities between the push plate 5 and the screen plate 4, the first driving device will continue to drive the push plate 5 to move to the right. The push plate 5 cannot continue to move to the right due to the resistance of the large particles of solid impurities. The push rod 7 will move in the second slide groove 501 and squeeze the first spring 8 to prevent the large particles of solid impurities from being continuously pushed by the push plate 5 and causing the screen plate 4 to deform or be blocked.
[0028] In this embodiment, the first driving device includes a support base 11 and a cylinder 12. The cylinder 12 is arranged on the support base 11. The output end of the cylinder 12 is connected to the buffer device. The cylinder 12 drives the push rod 7 to move back and forth when it works. The push rod 7 pulls the push plate 5 to the left through the first pull rope 9.
[0029] In this embodiment, a water trough 106 is provided on the feed barrel 10, and an avoidance groove 502 is provided on the push plate 5, and one end of the top wall of the avoidance groove 502 is an inclined surface; the second driving device includes a T-shaped pressure rod 13, a second spring 14, an abutment rod 15, a plurality of nozzles 16 and a conduction device, one end of the pressure rod 13 is in contact with the wall of the avoidance groove 502, and the other end can slide in the water trough 106, the second spring 14 is arranged in the water trough 106, and the abutment rod 15 is arranged on the feed barrel 10 and in contact with the bottom end of the receiving plate 6. When there are particulate impurities on the receiving plate 6, the conduction device works to energize the external water supply equipment to supply water to the nozzle 16, and the cylinder 12 drives the push plate 6. When the plate 5 moves rightward, the wall of the avoidance groove 502 on it exerts downward pressure on the pressure rod 13. The pressure rod 13 moves downward in the water trough 106 and compresses the second spring 14. The water in the water trough 106 is squeezed and drives the receiving plate 6 to move upward in the placement groove 104. The top of the receiving plate 6 is flush with the lower inner wall of the first outlet 103. After the cylinder 12 drives the push plate 5 to move leftward and return to its original position, the second spring 14 exerts a reaction force on the pressure rod 13 to return it to its original position. Under the action of its own gravity, one end of the receiving plate 6 moves downward at the right end of the water trough 106. When impurities are on the receiving plate 6, the conduction device is activated to energize the external water supply equipment to supply water to the nozzle 16. The nozzle 16 blows the impurities on the receiving plate 6 off and the impurities are discharged from the long groove 105 along with the water. Specifically, a discharge pipe is provided at the bottom of the long groove 105; the water pipe of the external water supply equipment passes through the vacuum box 2 and the feed cylinder 10 and is connected to the nozzle 16.
[0030] In this embodiment, the abutment rod 15 is in an I-shape and can slide on the feed barrel 10; the conducting device includes a first conductive block 17 and two second conductive blocks 18 and a third spring 19, the first conductive block 17 is arranged on the abutment rod 15, the second conductive block 18 is arranged on the feed barrel 10, and the third spring 19 connects the feed barrel 10 and the abutment rod 15. When the push plate 5 moves to the right, the receiving plate 6 moves upward to receive the mud material. During the upward movement of plate 5, the receiving plate 6 moves downward. When there are large particles of solid impurities on the receiving plate 6, one end of the push plate 5 cannot contact the screen plate 4, and mud and impurities will accumulate on the receiving plate 6. The heavier weight of the receiving plate 6 will increase the downward movement distance of the abutment rod 15, so that the first conductive block 17 and the two second conductive blocks 18 are connected, and the external water supply equipment is energized to supply water to the nozzle 16; the third spring 19 is a tension spring; the first conductive block 17 is embedded in the abutment rod 15, and the abutment rod 15 is not conductive.
[0031] In this embodiment, the receiving plate 6 is provided with a cavity 601, a water inlet hole 602, a baffle 603 and a limiting rod 604. The cavity 601 is respectively communicated with the water trough 106 and the water inlet hole 602. The limiting rod 604 is tilted on the receiving plate 6. One end of the limiting rod 604 is connected to the baffle 603. After the nozzle 16 sprays water, the water passes through the water inlet hole 602 to give thrust to the baffle 603, driving the limiting rod 604 to move upward on the receiving plate 6. The baffle 603 is separated from the water inlet hole 602. The nozzle 16 supplies water to the water trough 106 to prevent the water in the water trough 106 from becoming less during long-term use. When the nozzle 16 does not spray water, the limiting rod 604 returns to its original position due to the gravity of itself and the baffle 603.
[0032] In this embodiment, the feed barrel 10 is provided with a third chute 107, and the sieve plate 4 can slide in the third chute 107; it also includes a third driving device, which includes a first motor 20, a wire rod 21 and a second pull rope 22. The first motor 20 is provided on the vacuum box 2 to drive the wire rod 21 to rotate, and the second pull rope 22 connects the sieve plate 4 and the wire rod 21. When the sieve plate 4 needs to be replaced after long-term use, the first motor 20 drives the wire rod 21 to rotate and retract the second pull rope 22, and the sieve plate 4 is pulled out of the third chute 107. A new sieve plate 4 is replaced and then placed in the third chute 107. Specifically, a hook is provided on the sieve plate 4, and one end of the second pull rope 22 is tied to the hook.
[0033] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
