Description

Technical Field

[0001] This utility model relates to the field of kitchen waste recycling technology, and in particular to a water pump filtration device. Background Technology

[0002] Black soldier flies are saprophytic insects belonging to the family genus *Strombidae*. They feed on livestock manure and household waste, producing high-value animal protein feed. Due to their rapid reproduction, large biomass, wide diet, high absorption and conversion rate, ease of management, low feeding costs, and good palatability to animals, they are utilized as a resource. Black soldier flies are generally raised by feeding them kitchen waste, but the kitchen waste needs to be filtered and separated so that the usable portion can be used for raising black soldier flies.

[0003] According to the search, a Chinese invention patent (application publication number: CN118988946A) provides a device for preventing clogging of kitchen waste, including: a heating base, a filter assembly, and a sealing assembly;

[0004] The filter assembly includes an upper filter screen, a lower filter screen, and a support frame. The support frame is provided inside the recycling bin. The upper and lower filter screens are fixed on the upper and lower sides of the support frame, respectively. The upper filter screen is located directly above the lower filter screen. Multiple sealing components are arranged around the inner side of the support cover. A collection cylinder is fixed in the center of the filter assembly, and multiple water outlet holes are fixed through the side wall of the collection cylinder.

[0005] The sealing assembly includes a retaining ring, a first sealing cover, a second sealing cover, and a third sealing cover. The first sealing cover is fixed to the outside of the retaining ring, and the second sealing cover is slidably sealed to the inside of the sealing cover. A square hole is provided through the second sealing cover on the side close to the first sealing cover, and the third sealing cover is slidably sealed to the inside of the second sealing cover. An air outlet is provided through the bottom of the third sealing cover.

[0006] The outer wall of the first sealing cover has a through hole, and the position of the through hole corresponds to the position of the limiting hole. The ends of multiple hoses away from the bucket lid pass through the limiting hole and the through hole respectively to form a communication structure with multiple sealing covers. The inner wall of the first sealing cover is slidably provided with a slider.

[0007] When the sealing assembly is closed, the cleaning fluid inside the support cover will cause the eggshells and eggshell fragments to float. As the cleaning fluid flows out of the collection cylinder, it will carry the floating eggshells and eggshell fragments into the collection cylinder, thereby further screening the eggshells and eggshell fragments from the other waste and facilitating the separate recycling of eggshells and eggshell fragments from the waste. However, some waste may contain larger solid waste, such as broken chopsticks. If these are not screened out, they will be pumped out by the water pump, which will damage the pump blades. Furthermore, the structure of the above-mentioned existing technology is relatively complex, so there is an urgent need to improve this shortcoming. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] like Figures 1-8 As shown, a water pump filtration device includes a cylindrical body 1, an end cap 11 disposed on the cylindrical body 1, and a filtration assembly. A support frame 14 is provided on the outer periphery of the cylindrical body 1. An inlet pipe 12 and a drain pipe 13 are provided on the cylindrical body 1. A filtration chamber 10 is provided inside the cylindrical body 1. The inlet pipe 12 and the drain pipe 13 are both connected to the filtration chamber 10. The drain pipe 13 is connected to an external water pump. The filtration assembly is installed inside the filtration chamber 10 and is disposed between the inlet pipe 12 and the drain pipe 13. The filtration assembly includes an outer filter cylinder 31, a middle filter cylinder 32, and an inner filter cylinder 33, which are sequentially nested from the outside to the inside. The outer filter cylinder 31 is provided with a first filter hole 310. The middle filter cylinder 32 is provided with a second filter hole 320. The inner filter cylinder 33 is provided with a third filter hole 330. The first filter hole 310, the second filter hole 320, and the third filter hole 330 are all staggered.

[0032] The inlet pipe 12 is located above the filter assembly, and the drain pipe 13 is located below the filter assembly. The drain pipe 13 is an "L" shape with its opening facing downwards. Since some heavier solid waste will sink directly to the bottom, while lighter solid waste will float on the water surface, the downward opening of the drain pipe 13 can prevent solid waste on the water surface from being pumped out by the water pump, thereby preventing damage to the water pump.

[0033] The first filter hole 310, the second filter hole 320 and the third filter hole 330 are each provided in a plurality of units. The first filter hole 310 is evenly arranged on the first filter cylinder, the second filter hole 320 is evenly arranged on the second filter cylinder, and the third filter hole 330 is evenly arranged on the third filter cylinder, thereby realizing multi-layer filtration of solid waste and preventing solid waste from falling below the filter assembly.

[0034] The outer filter cylinder 31 is provided with a first bottom plate 312, the middle filter cylinder 32 is provided with a second bottom plate 321, and the inner filter cylinder 33 is provided with a third bottom plate 331. The first bottom plate 312, the second bottom plate 321, and the third bottom plate 331 are stacked from top to bottom to form a connecting plate 35. The inner wall of the filter cavity 10 is provided with a limiting plate 101 that cooperates with the connecting plate 35. The limiting plate 101 is used to restrict the movement of the outer filter cylinder 31, the middle filter cylinder 32, and the inner filter cylinder 33 in the axial direction of the cylinder body 1, thereby limiting the lower limit position of the outer filter cylinder 31, the middle filter cylinder 32, and the inner filter cylinder 33.

[0035] The limiting plate 101 is provided with a plurality of guide plates 102, which are evenly arranged on the limiting plate 101. The connecting plate 35 is provided with guide grooves 300 that correspond one-to-one with the guide plates 102. Each guide plate 102 is provided with a locking groove 1021. The connecting plate 35 is rotatably engaged with the guide plates 102 through the locking grooves 1021. When the connecting plate 35 rotates to the point where the guide grooves 300 and the guide plates 102 are misaligned, the connecting plate 35 is axially limited between the guide plates 102 and the limiting plate 101.

[0036] During installation, the guide groove 300 is aligned with the guide plate 102, thereby causing the connecting plate 35 to move downward along the height direction of the guide plate 102, so that the bottom of the connecting plate 35 abuts against the upper end of the limiting plate 101. By rotating the connecting plate 35, the guide groove 300 is misaligned with the guide plate 102, thereby restricting the movement of the connecting plate 35 in the axial direction of the cylinder 1.

[0037] The first base plate 312 is provided with a first positioning hole 313, the second base plate 321 is provided with a second positioning hole 322, and the third base plate 331 is provided with a positioning pin 332. The first positioning hole 313, the second positioning hole 322 and the positioning pin 332 are coaxially correspondingly arranged. The positioning and installation between the outer filter cylinder 31, the middle filter cylinder 32 and the inner filter cylinder 33 are realized by the positioning pin 332.

[0038] It should be noted that the diameters of the first base plate 312, the second base plate 321, and the third base plate 331 are all equal.

[0039] The outer filter cylinder 31 is provided with a first through hole, the middle filter cylinder 32 is provided with a second through hole, and the inner filter cylinder 33 is provided with a third through hole. The first through hole, the second through hole, and the third through hole are coaxially arranged, and a common connecting member 34 is inserted into the first through hole, the second through hole, and the third through hole. The connecting member 34 fixes the outer filter cylinder 31, the middle filter cylinder 32, and the inner filter cylinder 33 together.

[0040] The connector 34 includes a bolt 345, a nut 344, a pull ring 341, and a retaining plate 342. The retaining plate 342 is inserted into the outer filter cylinder 31. The retaining plate 342 is provided with a retaining groove 343. The nut 344 is fixedly installed in the retaining groove 343. The pull ring 341 is disposed on the retaining plate 342.

[0041] The upper end of the outer filter cylinder 31 is provided with a handle 311. In this application, there are two handles 311, and the two handles 311 are symmetrically installed on the upper end of the outer filter cylinder 31.

[0042] The end cap 11 is provided with a vent screw 111. When it is necessary to clean the outer filter cartridge 31, the middle filter cartridge 32 and the inner filter cartridge 33, the end cap 11 needs to be opened. Before opening the end cap 11, the vent screw 111 needs to be opened to release the negative pressure state.

[0043] The bottom of the cylinder 1 has a water outlet 113. A discharge assembly for opening and closing the water outlet 113 is installed at the bottom of the cylinder 1. The discharge assembly includes a connecting shell 21, a water outlet pipe 22 installed in the connecting shell 21, and a switch valve 23. The switch valve 23 is connected to the water outlet pipe 22. The water outlet pipe 22 is provided with a plurality of evenly arranged drain holes 220. When the discharge assembly is connected to the cylinder 1, the drain holes 220 are located in the filter chamber 10.

[0044] The bottom of the cylinder 1 is provided with a first mounting plate 112, and the outer periphery of the connecting shell 21 is provided with a second mounting plate 211. The outer periphery of the first mounting plate 112 and the second mounting plate 211 is provided with a retaining ring 24, which is detachably connected to the outer periphery of the first mounting plate 112 and the second mounting plate 211.

[0045] The retaining ring 24 is made of an elastic material and has an annular groove 241 inside. The first mounting plate 112 and the second mounting plate 211 are disposed in the annular groove 241, thereby achieving a fixed fit between the first mounting plate 112 and the second mounting plate 211.

[0046] When it is necessary to clean the outer filter cartridge 31, the middle filter cartridge 32, and the inner filter cartridge 33, first open the vent screw 111 to release the negative pressure, thereby opening the end cover 11. Manually hold the handle 311 and rotate it to align the guide groove 300 with the guide plate 102 and pull it upward. After pulling it out, rotate the bolt 345 to disengage the bolt 345 from the nut 344, thereby allowing the outer filter cartridge 31, the middle filter cartridge 32, and the inner filter cartridge 33 to be disassembled, and then cleaned respectively.

[0047] When drainage is required from the bottom, the water in the filter chamber 10 is discharged through the outlet pipe 22 by opening the switch valve 23. When it is necessary to clean the residue in the filter chamber 10, simply remove the retaining ring 24 and disconnect the connecting shell 21, so that the residue in the filter chamber 10 falls out of the outlet 113.
