Description

A powder filter barrel Technical Field

[0001] This utility model relates to the field of powder filtration processing technology, specifically a powder filter barrel. Background Technology

[0002] A powder filter is an industrial device used to separate powdery impurities from fluids (gases). It mainly uses filter media to trap powder particles, thereby purifying the fluid or recovering the powder. Its core function is to use the difference in pore size of the filter media to separate solid particles from the fluid. It is widely used in industries such as chemical, food, pharmaceutical, environmental protection, and metal processing.

[0003] Existing powder filter cartridges have some shortcomings in use. They are prone to clogging when filtering powder impurities from fluids over a long period of time, and cleaning them is relatively difficult for operators. Traditional filter cartridges are mostly fixed inside the outer shell with bolts, making disassembly and cleaning of the internal filter cartridges cumbersome and requiring tools, which is time-consuming, labor-intensive, and requires long downtime, reducing the efficiency of powder filtration. To address these issues, an improved and upgraded powder filter cartridge is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a powder filter barrel to solve the problem that existing devices are prone to clogging when filtering fluid powders over a long period of time, but lack the technical capability for quick disassembly and cleaning of the filter barrel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a powder filter barrel, including a filter barrel shell, an observation window fixedly provided on the outer wall of the filter barrel shell, a sealed cabinet door rotatably installed on the outer wall of the observation window, three snap-fit ​​plates fixedly provided on the outer wall of the sealed cabinet door, a cover plate provided on the top of the filter barrel shell, a limiting ring fixedly provided at one end of both the filter barrel shell and the cover plate, two limiting rings having mounting grooves of the same size inside, a limiting frame fixedly provided at the bottom of one limiting ring directly below the mounting groove, a guide rod fixedly provided inside the limiting frame, and a filter cylinder provided inside the filter barrel shell;

[0006] The outer wall of the filter cartridge is fixedly provided with a disassembly structure, which includes four support plates fixedly installed on the inner wall of the filter cartridge shell. Each support plate has a fixed block fixedly installed at its upper end, and each fixed block has a hinge seat fixedly installed at its upper end. A movable plate is rotatably installed inside the hinge seat. A U-shaped clamping pipe is rotatably connected to the outer wall of the movable plate. The U-shaped clamping pipe is clamped to a limiting block. The limiting block is fixedly installed on the clamping block, and the clamping block is fixedly installed on the outer wall of the filter cartridge.

[0007] Furthermore, multiple filter screens are fixedly installed inside the filter cylinder, and the pore size of the multiple filter screens decreases sequentially. The filter screens are made of metal wire. One end of each of the four snap-fit ​​blocks is inserted into the support plate. The U-shaped snap-fit ​​tube is adapted to the size of the limiting block. A feed pipe is fixedly installed on the outer wall of the cover plate and is positioned opposite to the upper end of the filter cylinder.

[0008] Furthermore, the number of the limiting brackets is set in two sets, and the other set is fixedly installed on the outer wall of the observation window. A screw is rotatably installed on the outer wall of the guide rod, and a limiting cap is threadedly connected to the outer wall of the screw. The two sets of limiting caps are respectively set on one of the limiting rings and the snap-fit ​​plate. The snap-fit ​​plate has an installation groove with the same size as the limiting ring inside.

[0009] Furthermore, a base is fixedly installed at the bottom of the filter barrel shell, and a discharge pipe connected to the bottom of the filter barrel shell is fixedly installed on the outer wall of the base. A fan is fixedly installed on one side of the base.

[0010] Furthermore, a sealing groove is provided inside the observation window, and a sealing ring is fixedly fitted inside the sealing groove. A sealing gasket is fixedly provided on the inner wall of the sealed cabinet door, and the sealing gasket is adapted to the size of the sealing groove.

[0011] Furthermore, a handle is rotatably mounted on the upper end of the filter cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) By setting up a disassembly structure, the limiting ring on the cover plate and the limiting ring on the filter barrel shell are misaligned by using screws and limiting caps. Then, the movable plate on the hinge seat is manually pressed to cause the movable plate to drive the U-shaped clamping pipe to be misaligned from the limiting block. Then, the handle is manually pulled to pull the filter barrel out of the support plate through the four clamping blocks. This facilitates quick disassembly of the filter barrel for cleaning the internal filter screen, avoiding problems such as disassembly difficulties caused by bolt fixing, which affect the filtration effect of liquids and powders. It reduces the burden on the staff, is simple to operate, and is convenient to disassemble and assemble.

[0014] 2) By setting up a sealed structure, the filter cartridge can be inspected through the observation window by opening the sealed cabinet door to judge the blockage inside. When the filter screen is severely blocked, the filter cartridge can be disassembled and cleaned. If it is not severely blocked, the filter can be filtered for a period of time before disassembly. At the same time, when the sealed cabinet door is closed, the sealing gasket squeezes the sealing ring in the sealing groove, causing the sealed cabinet door and the observation window to press and seal against each other, thereby improving the stability of liquid powder filtration.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Referring to Figures 1-5, a powder filter barrel includes a filter barrel shell 1, an observation window 10 fixedly installed on the outer wall of the filter barrel shell 1, a sealed cabinet door 4 rotatably installed on the outer wall of the observation window 10, three snap-fit ​​plates 41 fixedly installed on the outer wall of the sealed cabinet door 4, a cover plate 2 installed on the top of the filter barrel shell 1, a limit ring 3 fixedly installed at one end of both the filter barrel shell 1 and the cover plate 2, and an installation groove 31 of the same size opened inside both limit rings 3, a limit frame 35 fixedly installed at the bottom of one of the limit rings 3 directly below the installation groove 31, a guide rod 32 fixedly installed inside the limit frame 35, and a filter cylinder 6 installed inside the filter barrel shell 1.

[0024] The outer wall of the filter cartridge 6 is fixedly provided with a disassembly structure 8. The disassembly structure 8 includes four support plates 87 fixedly installed on the inner wall of the filter cartridge shell 1. Each support plate 87 has a fixed block 81 fixedly installed on its upper end, and each fixed block 81 has a hinge seat 83 fixedly installed on its upper end. A movable plate 84 is rotatably installed inside the hinge seat 83. A U-shaped clamping pipe 85 is rotatably connected to the outer wall of the movable plate 84. The U-shaped clamping pipe 85 is clamped to the limiting block 86. The limiting block 86 is fixedly installed on the clamping block 82, and the clamping block 82 is fixedly installed on the outer wall of the filter cartridge 6.

[0025] Referring to Figures 1 and 4, it is further seen that multiple filter screens are fixedly installed inside the filter cylinder 6, and the pore size of the multiple filter screens decreases sequentially. The filter screens are made of metal wire. One end of each of the four snap-fit ​​blocks 82 is inserted into the support plate 87. The U-shaped snap-fit ​​tube 85 is adapted to the size of the limiting block 86. A feed pipe is fixedly installed on the outer wall of the cover plate 2, and the feed pipe is aligned with the upper end of the filter cylinder 6. Two sets of limiting brackets 35 are provided, and the other set is fixedly installed on the outer wall of the observation window 10. The guide rod 3... 2. A screw 33 is rotatably installed on the outer wall. A limit cap 34 is threadedly connected to the outer wall of the screw 33. Two sets of limit caps 34 are respectively set on one of the limit rings 3 and the snap-fit ​​plate 41. The snap-fit ​​plate 41 has an installation groove 31 with the same size as the limit ring 3 inside. A base 5 is fixedly installed at the bottom of the filter barrel shell 1. A discharge pipe connected to the bottom of the filter barrel shell 1 is fixedly installed on the outer wall of the base 5. A fan 7 is fixedly installed on one side of the base 5. A handle 9 is rotatably installed on the upper end of the filter barrel 6.

[0026] Specifically, the filter cylinder 6 has three layers of filter screens, with the pore size decreasing from top to bottom to facilitate the interception and filtration of powder in the liquid. The filter screens are made of metal wire to increase their hardness and avoid damage caused by prolonged liquid impact. A handle 9 is provided to facilitate the removal and disassembly of the filter cylinder 6 by the staff. Four locking blocks 82 are interlocked with the support plate 87 for positioning. Two sets of screws 33, limit caps 34 and guide rods 32 are provided, with the other set fixedly installed on the outer wall of the observation window 10 for locking and positioning the sealed cabinet door 4.

[0027] Example 2

[0028] Referring to Figure 4, and based on Embodiment 1, it is further found that the observation window 10 has a sealing groove 101 inside, a sealing ring 102 is fixedly fitted inside the sealing groove 101, and a sealing gasket 42 is fixedly installed on the inner wall of the sealed cabinet door 4, with the sealing gasket 42 matching the size of the sealing groove 101.

[0029] Specifically, the sealing gasket 42 on the sealed cabinet door 4 and the sealing ring 102 on the observation window 10 are pressed against each other, which facilitates effective sealing when the sealed cabinet door 4 and the observation window 10 are in contact. The limit cap 34 and the screw 33 work together to lock the liquid, which helps to prevent leakage during powder filtration. At the same time, the filtration situation inside the filter cartridge 6 can be observed.

[0030] Work process: First, the staff feeds the liquid containing powder into the filter cylinder 6 inside the filter barrel shell 1 through the feed pipe. The liquid is then filtered by multiple filter screens with progressively smaller pore sizes inside the filter cylinder 6. At this time, the blower 7 is started so that the filtrate passes quickly through the surface of the filter screen under centrifugal pressure, which greatly improves the powder separation efficiency. Finally, the filtered liquid flows out through the discharge pipe at the rear of the base 5, completing the powder filtration operation.

[0031] For a long time, a large amount of powder impurities adhere to the surface of the filter screen inside the filter cartridge 6. By rotating the limit caps 34 on the outer side of the three snap-fit ​​plates 41 on the outer wall of the sealed cabinet door 4, the limit caps 34 are displaced from the snap-fit ​​plates 41 under the action of the screw 33. Then, the screw 33 is driven to rotate 90 degrees around the guide rod 32 on the limit frame 35. Then the sealed cabinet door 4 is opened, and the staff can observe the internal filter cartridge 6 through the observation window 10 to see if there is any blockage or poor filtration effect.

[0032] When the filter screen inside the filter cartridge 6 needs to be cleaned, the principle is the same as above. The bottom limiting ring 3 of the cover plate 2 and the upper limiting ring 3 of the filter cartridge shell 1 are misaligned by the screw 33 and the limiting cap 34, so that the cover plate 2 can be pulled off the filter cartridge shell 1. Then, by manually pressing the movable plate 84 on the hinge seat 83, the movable plate 84 causes the U-shaped clamping pipe 85 to be misaligned from the upper limit block 86 of the clamping block 82. Then, the operator manually pulls the handle 9 and uses the clamping block 82 to insert the filter cartridge 6 into the slots on the four support plates 87. The filter cartridge 6 can be quickly disassembled to clean the internal filter screen, preventing blockage and ensuring filtration efficiency. After cleaning, the four snap-fit ​​blocks 82 on the filter cartridge 6 are aligned with the support plate 87, and then the U-shaped snap-fit ​​tube 85 on the movable plate 84 is used to limit the filter cartridge 6 with the limiting block 86. Finally, the limiting ring 3 on the cover plate 2 is aligned with the filter cartridge shell 1, and the limiting cap 34 is screwed into the screw rod 33 for quick disassembly and assembly of the filter cartridge 6. The operation is simple and convenient.

[0033] After the filter cartridge 6 is installed, by closing the sealed cabinet door 4, the sealing gasket 42 and the sealing groove 101 on the observation window 10 are squeezed against each other, causing the sealing gasket 42 and the sealing ring 102 to be squeezed together, thus sealing the gaps and avoiding problems such as leakage caused by poor sealing effect during powder filtration, thereby improving the stability of powder filtration.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
