Description

Technical Field

[0001] The utility model relates to the technical field of dipping slurry devices, and particularly relates to a dipping slurry device for preparing silicon carbide ceramic filter screens. Background Technique

[0002] A dipping slurry device is an industrial equipment used to immerse an object into a liquid slurry so as to coat or deposit a layer of material on the surface of the object.

[0003] The prior art discloses a utility model patent with the name: A dipping slurry device for making shell molds for green environmental protection wax molds for bucket teeth castings, and the publication number is: CN216441611U. It includes a fixed box, a conveyor belt, a clamping mechanism and a heating box. Among them, the conveyor belt is arranged horizontally on the upper part of the fixed box, and a slurry tank and a heating box are sequentially arranged in the lower part of the fixed box from left to right in the direction of the conveyor belt's travel.

[0004] However, in the heating box described in the patent application specification, it is arranged on the right side of the slurry tank, and a diversion plate with an inclination angle of 12 degrees to the horizontal direction is installed at the bottom of the heating box. During the production process, when the slurry on the surface of the shell mold drips off, it converges in the groove formed by the diversion plate and the bottom of the heating box via the diversion plate. Since this groove is in the horizontal direction, the dripping slurry cannot be quickly discharged from the heating box, and due to the heating function of the drying box, the slurry in the converging groove will dry up, not only unable to recover the dripping slurry, but also causing blockage of the drain port. Content of the Utility Model

[0005] The utility model aims to solve the problems existing in the prior art, and provides a dipping slurry device for preparing silicon carbide ceramic filter screens, which can effectively recover the slurry dripping from the surface of the green body during the preparation of the silicon carbide ceramic filter screen, avoid blockage of the drain port, and improve production efficiency and economy.

[0006] To achieve the above object, the present application provides a dipping slurry device for preparing silicon carbide ceramic filter screens, which includes a fixing part, a conveyor belt, a clamping part, a slurry tank and a heating box. The fixing part includes a fixed box and a bottom foot bracket, and the bottom foot bracket is installed at the lower part of the fixed box; a conveyor belt extending outside the fixed box is installed on the upper part of the fixed box, a clamping part is installed under the conveyor belt, a heating box and a slurry tank are sequentially arranged in the fixed box from top to bottom, and the drain port at the bottom of the heating box is directly above the slurry tank.

[0007] Further, the conveyor belt includes a straight section, a descending section and a lifting section.

[0008] The clamping part includes a fixed pneumatic telescopic rod, a clamping seat and an adjusting mechanism. The fixed pneumatic telescopic rods are equidistantly installed on the conveyor belt. The output end of the fixed pneumatic telescopic rod is equipped with a clamping seat, and the adjusting mechanism is installed on the inner side of the clamping seat.

[0009] Further, the adjusting mechanism includes two clamping plates, a stud and a hexagonal nut. One of the two clamping plates is fixed to the inner side of one end of the clamping seat, and the other is fixed to the inner side of the other end of the clamping seat through the stud and the hexagonal nut.

[0010] The slurry tank consists of a tank body, a liquid inlet, a liquid outlet and a plug. The slurry tank is welded and fixed on the left side of the fixed box. The tank body is used to hold slurry. The liquid inlet is located on the left side of the tank body and is flush with the upper surface of the tank body. The liquid outlet is located below the tank body. Plugs are installed at the input end of the liquid inlet and the output end of the liquid outlet to open and close the liquid inlet and the liquid outlet.

[0011] Further, the liquid inlet and the liquid outlet are connected to the slurry tank and penetrate through the fixed box.

[0012] Further, the plugs are installed at the input end of the liquid inlet and the output end of the liquid outlet and are located outside the fixed box.

[0013] The heating box includes: a box body, a heating pipe and a drying box. The heating box is welded and fixed on the right side of the fixed box, and the heating box is located directly above the slurry tank.

[0014] Further, the box body includes a conical part and a cylindrical part. The liquid outlet is installed below the conical part. The drying boxes are installed on both sides of the box body, and the heating pipes are installed inside the drying boxes.

[0015] The beneficial effects of this application are as follows:

[0016] 1. For the slurry dipping device for preparing silicon carbide ceramic filter screens in this application, its conveyor belt is divided into a descending section, a straight section and a lifting section, which can shorten the process of the green body entering the drying box after slurry dipping, and reduce the possibility that the slurry covering the surface of the green body drips from the surface of the green body due to its own weight, thereby affecting the pore structure of the silicon carbide ceramic filter screen.

[0017] 2. The clamping part of this application includes an adjusting mechanism, and the gap between the two clamping plates can be controlled by the hexagonal nut on its side, so as to achieve the purpose of clamping green bodies of different sizes.

[0018] 3. The lower part of the heating box of this application is a conical part, which can effectively prevent the dripping slurry from converging at the bottom of the heating box, thereby avoiding the blockage of the liquid outlet caused by the drying of the slurry.

[0019] 4. The heating box of this application is arranged above the slurry tank. The dripping slurry finally flows out of the drainage port through the conical part of the heating box and reaches the inside of the slurry tank, which may effectively complete the recovery of the dripping slurry.

[0033] The fixing part 1 includes a fixing box 11 and a bottom foot bracket 12. The bottom foot bracket 12 is installed at the lower part of the fixing box 11 and is used to support and stabilize the fixing box 11.

[0034] The slurry tank 4 is composed of a tank body 41, a liquid inlet 42, a drain port 43 and a plug 44. The slurry tank 4 is fixedly welded on the left side of the fixing box 11. The tank body 41 is used to hold the slurry. The liquid inlet 42 is located on the left side of the tank body 41 and is flush with the upper surface of the tank body 41. The drain port 43 is located below the tank body 41. Plugs 44 are installed at the input end of the liquid inlet 42 and the output end of the drain port 43 to open and close the liquid inlet 42 and the drain port 43.

[0035] Further, the liquid inlet 42 and the drain port 43 are connected to the slurry tank 4 and penetrate through the fixing box 11.

[0037] The conveyor belt 2 includes a straight section 21, a descending section 22 and a lifting section 23. The moving direction of the conveyor belt 2 is from left to right.

[0038] The clamping part 3 includes a fixed pneumatic telescopic rod 31, a clamping seat 32 and an adjusting mechanism 33. The fixed pneumatic telescopic rods 31 are equidistantly installed on the conveyor belt 2. A clamping seat 32 is installed at the output end of the fixed pneumatic telescopic rod 31.
