Description

Technical Field

[0001] This utility model relates to the field of zirconia filtration technology, specifically a filtration device for zirconia slurry. Background Technology

[0002] The filtration device for zirconia slurry mainly needs to solve problems such as strong slurry adhesion and easy clogging of the filter screen, while also taking into account filtration efficiency and slurry dispersibility.

[0003] A filtration device for zirconium hydroxide slurry, disclosed in CN 215693218 U, includes a filter chamber and a coarse filter, a fine filter, and a disperser disposed within the filter chamber. The filter chamber has openings at the top and bottom; the top opening is the feed inlet, and the bottom opening is the discharge outlet. The coarse and fine filters are horizontally positioned within the filter chamber, dividing the chamber space into three parts. The coarse filter is located above the fine filter. The disperser includes blades and a shaft. The shaft is vertically positioned at the center of the filter chamber, with a dispersing motor connected to its top and the blades connected to its bottom. The blades are positioned between the coarse and fine filters. The shaft passes through the coarse filter. This invention reduces the rate at which the filter becomes clogged, thereby reducing the workload of cleaning the filter screens. It also increases the filtration speed, thus improving zirconium oxide production efficiency. Simultaneously, the disperser enhances the dispersibility of the slurry, thereby improving the quality of the zirconium oxide powder.

[0004] When zirconia slurry is poured into the top filter chamber from one side, excessive local pressure can occur on the filter screen during production, causing screen deformation and affecting filtration quality. Additionally, air bubbles in the slurry can adhere to the filter screen, further reducing filtration efficiency. Therefore, a filtration device for zirconia slurry is needed to address these issues.

[0005] The purpose of this invention is to provide a filtration device for zirconium oxide slurry, thereby solving the problems mentioned in the background section. To solve these technical problems, this invention is achieved through the following technical solution:

[0006] This utility model relates to a filtration device for zirconium oxide slurry, comprising:

[0007] A filter assembly, comprising a filter chamber, a fine filter screen, and a coarse filter screen, wherein there are three filter chambers, and the fine filter screen and the coarse filter screen are respectively fixed between two filter chambers;

[0008] The flow diversion assembly includes a spiral guide plate, a material passage hole, a side plate, and a baffle. The spiral guide plate is fixed inside the uppermost filter chamber, the material passage hole is opened on the spiral guide plate and is evenly distributed, the side plate is fixed in the inner ring of the spiral guide plate, and the baffle is fixed at the uppermost end of the spiral guide plate.

[0009] Furthermore, the diversion assembly also includes a sealing strip, which is fixed to the outer ring of the spiral guide plate and fits against the inner wall of the uppermost filter chamber.

[0010] Furthermore, the coarse filter screen is located above the fine filter screen, and the pore size of the coarse filter screen is larger than that of the fine filter screen.

[0011] Furthermore, the filter assembly also includes a device support base and a support frame. The device support base is fixed to the ground and has a servo motor installed at its upper end. The support frame is fixed in the middle of the device support base, and the lowest filter compartment is fixed on the support frame.

[0012] Furthermore, the filter assembly also includes a propeller shaft and blades. The propeller shaft is fixed to the output end of the servo motor on the upper end of the equipment support base, and the propeller shaft passes through and is rotatably connected to the middle of the coarse filter screen. The blades are fixed to the lower end of the propeller shaft and located at the upper end of the fine filter screen.

[0013] Furthermore, it also includes a connecting component, which includes an L-shaped support plate and a mounting plate. The mounting plate is fixed to the spiral guide plate and is evenly distributed. The L-shaped support plate is fixed to the middle of the upper part of the mounting plate, and its upper end is placed on the uppermost filter compartment.

[0014] Furthermore, the connecting assembly also includes a through hole and a bolt. The through hole is located in the middle of the upper part of the L-shaped support plate, and the bolt is fixed to the upper end of the uppermost filter chamber, with the through hole fixed to the bolt.

[0015] This utility model has the following beneficial effects:

[0016] This invention utilizes a diversion component to pour zirconia slurry downwards from the uppermost baffle of a spiral guide plate. The zirconia slurry flows downwards from the spiral guide plate, with a portion falling through the first feed hole. Due to the slurry's viscosity, most of it continues to flow downwards. After passing through the second feed hole, another portion falls, and the slurry continues to flow. A further portion falls through the third feed hole, and the final slurry flows out from the bottom of the spiral guide plate. This design allows the zirconia slurry to fall dispersedly onto the coarse filter screen, reducing local pressure on the screen, extending its service life, and simultaneously prolonging the time the slurry spends on the screen, providing sufficient time for bubble bursting.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-3 As shown, this utility model is a filtration device for zirconium oxide slurry, comprising:

[0026] The filter assembly includes a filter chamber 14, a fine filter screen 15, and a coarse filter screen 16. There are three filter chambers 14 in total, and the fine filter screen 15 and the coarse filter screen 16 are fixed between two filter chambers 14 respectively.

[0027] The filter assembly also includes a device support base 10 and a support frame 11. The device support base 10 is fixed on the ground and a servo motor is installed at the upper end. The support frame 11 is fixed in the middle of the device support base 10 and the lowest filter chamber 14 is fixed on the support frame 11.

[0028] The filter assembly also includes a shaft 12 and a blade 13. The shaft 12 is fixed to the output end of the servo motor at the upper end of the equipment support base 10, and the shaft 12 passes through and is rotatably connected to the middle of the coarse filter screen 16. The blade 13 is fixed to the lower end of the shaft 12 and is located at the upper end of the fine filter screen 15.

[0029] The equipment support base 10 provides support for the filter chamber 14 and the servo motor. The support frame 11 supports the filter chamber 14. The propeller shaft 12 drives the blades 13 to rotate. The rotation of the blades 13 can prevent the fine filter screen 15 from clogging and at the same time apply a downward force to accelerate the downward filtration of the slurry. The filter chamber 14 provides a container for filtration. The fine filter screen 15 is used to filter fine particles, and the coarse filter screen 16 is used to filter larger particles.

[0030] The flow divider assembly includes a spiral guide plate 20, a material passage hole 22, a side plate 23, and a baffle 24. The spiral guide plate 20 is fixed inside the uppermost filter chamber 14. The material passage hole 22 is opened on the spiral guide plate 20 and is evenly distributed. The side plate 23 is fixed in the inner ring of the spiral guide plate 20, and the baffle 24 is fixed at the uppermost end of the spiral guide plate 20.

[0031] The diversion assembly also includes a sealing strip 21, which is fixed to the outer ring of the spiral guide plate 20 and fits against the inner wall of the uppermost filter chamber 14.

[0032] The coarse filter 16 is located above the fine filter 15, and the filter holes of the coarse filter 16 are larger than those of the fine filter 15.

[0033] The spiral guide plate 20 serves as a guide, the sealing strip 21 serves as a seal, the material passage hole 22 is used for material discharge, and the side plate 23 and the baffle 24 serve as blocking functions.

[0034] Working principle:

[0035] Place the spiral guide plate 20 into the uppermost filter chamber 14, ensuring the sealing strip 21 adheres to the inside of the filter chamber 14. Secure the spiral guide plate 20, and pour zirconia slurry downwards from the uppermost baffle 24 of the spiral guide plate 20. The slurry is blocked by the side plate 23 and flows downwards along the spiral guide plate 20. When it passes through the first feed hole 22, a portion falls off. Due to the viscosity of the slurry, most of it continues to flow downwards. After passing through the second feed hole 22, a portion of the slurry falls off again and continues to flow. A portion of the slurry continues to fall off through the third feed hole 22, and the final slurry flows out from the bottom of the spiral guide plate 20.

[0036] This step allows the zirconium oxide slurry to fall dispersedly onto the coarse filter screen 16, reducing the local pressure on the screen, extending its service life, and also extending the time the slurry falls onto the screen, providing sufficient time for bubble bursting.

[0037] Please see Figure 1 , Figure 3 As shown, this embodiment, based on the above embodiment, further includes:

[0038] The connecting assembly includes an L-shaped support plate 30 and a mounting plate 31. The mounting plate 31 is fixed on the spiral guide plate 20 and is evenly distributed. The L-shaped support plate 30 is fixed at the middle of the upper end of the mounting plate 31 and the upper end is placed on the uppermost filter chamber 14.

[0039] The connecting assembly also includes a through hole 32 and a bolt 33. The through hole 32 is opened in the middle of the upper end of the L-shaped support plate 30, and the bolt 33 is fixed to the upper end of the uppermost filter chamber 14. The through hole 32 is fixed to the bolt 33.

[0040] The L-shaped support plate 30 serves as a support and connection, the mounting plate 31 is used to connect the L-shaped support plate 30 and the spiral guide plate 20, and the through hole 32 and bolt 33 are used to fix the L-shaped support plate 30.

[0041] Working principle:

[0042] Fix the mounting plate 31 at the lower end of the L-shaped support plate 30 to the spiral guide plate 20 with screws. Hold the L-shaped support plate 30, align the through hole 32 with the screw of the bolt 33, tighten the nut of the bolt 33, and fix the spiral guide plate 20. Then you can start filtering the zirconia slurry.

[0043] This step facilitates the disassembly and assembly of the diversion components and is beneficial for subsequent cleaning of the filter chamber 14.
