[0025] The material storage mechanism 2 includes a material storage chamber 10, a liquid level sensor 11 and a lift 12. The side wall of the material storage chamber 10 is in contact with the inner wall of the coating box 1. The liquid level sensor 11 is arranged in the material storage chamber 10. The lower end of the lift 12 is connected to the bottom surface of the coating box 1, and the upper end is connected to the material storage chamber 10. The liquid level sensor 11 is connected to the lift 12. The lift 12 controls the operation of the lift 12 according to the liquid level signal received by the liquid level sensor 11. When the liquid level sensor 11 detects that the liquid level in the material storage chamber 10 is too low or too high, the lift 12 lifts the material storage chamber 10 to the required height, effectively controlling the liquid level in the material storage chamber 10 to ensure that the paint in the coating box 1 is always maintained within the required liquid level range.

[0026] like Figure 2 As shown, the drying mechanism 3 includes a drying box 13, a drying layer 14 and a gate 16. The drying layer 14 is arranged on the inner wall of the drying box 13. The gate 16 is a double-opening gate 16, which is arranged at the bottom of the drying box 13. A heating wire 15 is arranged in the drying layer 14; the gate 16 is in a normally open state. When the sponge block needs to be sintered at a low temperature, the telescopic rod 7 contracts and drives the dipping basket 8 to enter the drying box 13 through the gate 16. After the dipping basket 8 enters the drying box 13, the gate 16 is closed, and the heating wire 15 provides heating to increase the temperature in the drying box 13, so as to dry the sponge block at a low temperature.

[0027] Low-temperature drying by the drying mechanism 3 is faster than natural drying, and low-temperature drying can effectively evaporate the moisture in the ceramic slurry, so that the green body reaches a lower humidity, and at the same time, the green body reaches a uniform shrinkage state before high-temperature sintering and forms a stable surface layer before high-temperature sintering, which helps to reduce the formation of problems such as bubbles, cracks and deformation during the subsequent high-temperature sintering process, and improve the quality of the finished product.

[0028] The front ends of the drying box 13 and the coating box 1 are provided with transparent plates, such as Figure 3 As shown, a take-in and put-out port 21 is provided on the transparent plate corresponding to the coating box 1; the transparent plate allows the operator to clearly observe the conditions inside the drying box 13 and the coating box 1, which is convenient for monitoring and adjusting process parameters, while avoiding accidental injuries that may be caused when opening the box door, ensuring work safety. The take-in and put-out port 21 is used for placing sponge blocks for preparing ceramic filter screens, taking out coated green bodies, and adding ceramic slurry, etc.

[0029] The rotating mechanism 5 includes a rotating motor 17 and a fixed disc 18, wherein the rotating motor 17 is arranged on the outside of the coating box 1, and the fixed disc 18 is arranged on the inside of the coating box 1, and the rotating motor 17 is connected to the fixed disc 18 to control the rotation of the fixed disc 18; the fixed disc 18 is installed inside the drying box 13, and the telescopic rod 7 is arranged on the fixed disc 18, and the telescopic rod 7 passes through the gate 16 at the bottom of the drying box 13 and is connected to the dipping basket 8, and the rotating motor 17 controls the rotation of the fixed disc 18 to control the rotation of the dipping basket 8 to perform a centrifugal drying operation, and the length and width of the gate 16 are not less than the distance between the telescopic rods 7 connecting the dipping basket 8, and the rotating motor 17 can control the rotation speed and direction to meet different needs.

[0030] The telescopic rod 7 connected to the dipping basket 8 is arranged on both sides of the dipping basket 8, and the telescopic rod 7 connected to the extrusion plate 9 is arranged at the top of the extrusion plate 9, and the other end is connected to the fixed disc 18; by adjusting the height of the telescopic rod 7, the position of the dipping basket 8 and the extrusion plate 9 is adjusted to realize the coating and hanging operation of the sponge block, and the relative position of the dipping basket 8 and the extrusion plate 9 is adjusted to realize the limiting and extrusion of the sponge block.

[0031] like Figure 4 As shown, a plurality of through holes 19 are evenly arranged on the side wall of the dipping basket 8, and a long strip-shaped discharge port 20 is also arranged at the lower end of the side wall; the through holes 19 and the discharge port 20 are used for the immersion of ceramic slurry during the dipping process, and the discharge port 20 is arranged at the lower end. When the sponge block is squeezed to remove excess slurry, the ceramic slurry can be discharged along the discharge port 20 to prevent the ceramic slurry from being retained in the dipping basket 8. When centrifugal drying is performed, the through holes 19 and the discharge hole are used for discharging the coating.

[0032] It also includes a control mechanism 6, which is connected to the storage mechanism 2, the drying mechanism 3, the coating mechanism 4 and the rotating mechanism 5; it can monitor and adjust the parameters and states of the storage, drying, coating and rotation links, centrally manage the operation of the entire coating machine, realize automatic control of the coating process, and improve production efficiency and quality control; at the same time, the control mechanism 6 can also record the parameters and data in the coating process for technical personnel to conduct quality tracing and process optimization.

[0034] The sponge block is placed in the dipping basket through the access port, the squeezing plate descends to fix the sponge block in the dipping basket, and the dipping basket and the squeezing plate descend simultaneously into the storage chamber, so that the ceramic slurry in the storage chamber is immersed in the dipping basket and infiltrated into the sponge block for the first slurry coating. After the sponge block is soaked with the ceramic slurry, the dipping basket and the squeezing plate rise and separate from the storage chamber, the squeezing plate squeezes the sponge block to remove excess ceramic slurry from the sponge block and then lifts it up, the dipping basket rises to the drying mechanism for low-temperature drying to obtain a green body, the above dipping operation is repeated to coat the green body with slurry for the second time, after the dipping is completed, the rotating mechanism controls the rotation of the dipping basket, centrifugally slurries the green body, and removes excess ceramic slurry on the surface of the green body, the dipping basket rises to the drying mechanism for a second low-temperature drying, and after the drying is completed, it is taken out through the access port, the transferred green body is coordinated with other equipment to perform high-temperature sintering to obtain a finished ceramic filter.
