Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter technology, and in particular to a powder adding device for installing perlite filter equipment. Background Technology
[0002] Perlite filters are high-efficiency water treatment devices that use perlite powder as the filter medium. With a filtration accuracy of 1 micron, an intelligent regeneration system, and significant energy-saving advantages, they are widely used in swimming pools, water parks, hot springs, and other places.
[0003] The filter draws perlite powder from a powder tank for filtration. For easy powder replenishment, the powder tank is placed outside the filter. However, due to the often damp installation site, the powder tank is prone to moisture buildup. The damp powder clumps and can easily clog the connecting pipe between the filter and the powder tank. This blockage will cause the filter to remain in a suction state, which can damage the filter over time. Utility Model Content
[0004] The purpose of this application is to provide a powder feeding device for installing perlite filtration equipment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution:
[0006] A powder feeding device for installing a perlite filter includes a tank, a base, and a powder feeding assembly mounted on the base. The powder feeding assembly includes a sealing plate, multiple movable parts, and multiple lifting parts. The base is circular in shape, with a fixed plate fixedly installed at its center. Multiple circular holes are formed through the surface of the fixed plate. The movable parts are movably embedded within the circular holes of the fixed plate. The sealing plate is embedded at the bottom of the base. The multiple lifting parts are fixedly installed on the surface of the sealing plate. The lifting parts pass through the circular holes of the fixed plate and lift the movable parts. All the lifting parts and movable parts are cylindrical tubes, and vertical grooves are formed through their outer walls. Each movable part includes a top plate and a cylindrical tube. The top plate is fixedly installed on the top of the cylindrical tube, and the diameter of the top plate is larger than the circular holes on the fixed plate.
[0007] Preferably, the base has multiple mounting grooves on its bottom edge and multiple movable grooves on its bottom surface. The mounting grooves communicate with the movable grooves. Multiple fixing rods are fixedly installed on the edge of the sealing plate, and these fixing rods are all embedded inside the mounting grooves. The mounting groove is located in the middle of the movable groove. Clamping blocks are symmetrically installed on both sides of the movable groove. Springs are installed between the clamping blocks and the inner wall of the end of the movable groove. The shape of the fixing rods on the edge of the sealing plate matches the shape of the mounting groove. A handle is fixedly installed on the bottom surface of the sealing plate. A top cover is installed on the top of the tank. A powder suction pipe is installed on the surface of the fixed plate. The bottom end of the powder suction pipe communicates with the space between the fixed plate and the sealing plate. The top end of the powder suction pipe passes through the top cover and connects to the external filtration equipment pipeline.
[0008] The beneficial effects of this utility model are: by setting up a powder feeding component, after the powder enters the tank, the powder suction pipe will suck up the powder between the fixed plate and the sealing plate. Powder that can pass through the slots of the lifting part and the movable part will not cause blockage of the powder suction pipe. The sealing plate is easy to disassemble and assemble, and easy to clean. Attached Figure Description

[0015] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings.

[0016] like Figure 1-5 The diagram illustrates a powder feeding device for installing a perlite filter, comprising a tank 1, a base 2, and a powder feeding assembly mounted on the base 2. The powder feeding assembly includes a sealing plate 6, multiple movable parts 5, and multiple lifting parts 7. The base 2 is annular in shape, with a fixed plate 4 fixedly mounted at its center. Multiple circular holes are formed through the surface of the fixed plate 4. The movable parts 5 are movably embedded within these circular holes. The sealing plate 6 is embedded at the bottom of the base 2. The multiple lifting parts 7 are fixedly mounted on the surface of the sealing plate 6, passing through the circular holes of the fixed plate 4 to lift the movable parts 5. All lifting parts 7 and movable parts 5 are cylindrical tubes, with vertical grooves forming through their outer walls. Each movable part 5 includes a top plate and a cylindrical tube. The top plate is fixedly mounted on the top of the cylindrical tube, and its diameter is larger than the circular holes on the fixed plate 4.
[0017] The bottom edge of the base 2 has multiple mounting slots 9, and the bottom surface of the base 2 has multiple movable slots 10. The mounting slots 9 and the movable slots 10 are connected. Multiple fixing rods 8 are fixedly installed on the edge of the sealing plate 6, and the fixing rods 8 are all embedded inside the mounting slots 9. The mounting slot 9 is located in the middle of the movable slot 10. Clamping blocks 11 are symmetrically installed on both sides of the movable slot 10. Springs 12 are installed between the clamping blocks 11 and the inner wall of the end of the movable slot 10. The shape of the fixing rods 8 on the edge of the sealing plate 6 is adapted to the shape of the mounting slot 9. A handle 13 is fixedly installed on the bottom surface of the sealing plate 6. A top cover is installed on the top of the tank 1. A powder suction pipe 3 is installed on the surface of the fixed plate 4. The bottom end of the powder suction pipe 3 is connected to the space between the fixed plate 4 and the sealing plate 6. The top end of the powder suction pipe 3 passes through the top cover and connects to the external filtration equipment pipeline.
[0018] Example: When powder needs to be added, the operator opens the top cover of tank 1 and pours the perlite powder into the tank. At this time, the lifting component 7 lifts the movable component 5 upward. The powder passes through the groove on the outer wall of the lifting component 7 and the movable component 5, and then enters the area between the fixed plate 4 and the sealing plate 6. Subsequently, the outer wall filter device sucks the powder from between the fixed plate 4 and the sealing plate 6 through the powder suction pipe 3. When tank 1 needs to be cleaned, the operator can hold the handle 13 and pull the sealing plate 6 downward. The fixed rod 8 disengages from the mounting groove 9 and opens the two clamps 11 inside the movable groove 10. The spring 12 is compressed and deformed, the lifting component 7 separates from the round hole of the fixed plate 4, the movable component 5 descends, and the top plate of the movable component 5 fits against the outer wall of the fixed plate 4, sealing the round hole. At this time, the sealing plate 6 separates from the base 2, and the operator can clean the groove of the movable component 5 and the lifting component 7. After cleaning, push the sealing plate 6 into the bottom of the base 2, and the fixing rod 8 passes through the two clamps 11 and returns to the mounting slot 9. At this time, the slots of the movable part 5 and the lifting part 7 are cleaned, and the powder suction pipe 3 can continue to perform powder suction.

[0020] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
