Description

Technical Field

[0001] This utility model relates to the technical field of water pump components, specifically a water pump inlet structure. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing the liquid's energy. It is mainly used to transport liquids including water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. The inlet structure is an important component of the water pump for inputting liquid materials.

[0003] Unlike the input of clean solutions, when liquid materials contain clumps or solid impurities, although the water pump can transfer these substances, prolonged use can easily cause wear on the impeller inside the pump body due to solid impurities, thus reducing the service life of the water pump.

[0004] In view of this, a water pump inlet structure was designed to solve the above problems. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0032] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0033] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a water pump inlet structure. Example 1

[0034] Combination Figures 1-5 As shown, the present invention provides a water pump liquid inlet structure, including a liquid inlet mechanism 100 and a liquid inlet decontamination mechanism 200 disposed within the liquid inlet mechanism 100. The liquid inlet mechanism 100 is installed on the water pump and is used to provide an input platform for liquid materials. The liquid inlet decontamination mechanism 200 is used to filter impurities in the liquid materials.

[0035] The liquid inlet mechanism 100 includes a drain chamber 110, a ring gasket 160 installed inside the drain chamber 110, an outer end 130 located at the outer end of the drain chamber 110, an inner end 140 located at the inner end of the drain chamber 110, a second sleeve 150 installed inside the inner end 140, two first sleeves 120 installed inside the drain chamber 110, a limiting outer frame 170 installed on the ring gasket 160, and multiple load-bearing outer frames 180 installed on the ring gasket 160.

[0036] The limiting outer frame 170 has a slot in the end face near the ring pad 160 that is adapted to the pressure boosting inclined plate 284. The limiting outer frame 170 and multiple load-bearing outer frames 180 are all fitted with ring buckles on adjacent stainless steel ends, and bushings 190 are provided inside the ring buckles.

[0037] The liquid inlet cleaning mechanism 200 includes an inner pad 210 disposed between the ring pad 160 and the outer end 130, a plurality of diverter plates 220 disposed outside the inner pad 210, two third sleeves 270 mounted on the inner pad 210, a liquid boosting assembly 280 disposed within the two third sleeves 270, and two scrapers 290 disposed on the liquid boosting assembly 280.

[0038] The outer wall of the inner pad 210 is provided with multiple evenly distributed slots, and the protruding plate on the inner side of the diversion plate 220 is adapted to penetrate into the slots.

[0039] An internal ring gasket 250 is installed at the inner end of the inner gasket 210, and an anti-overflow ring gasket 260 is installed at the outer end of the inner gasket 210.

[0040] A traction assembly 230 is installed in the hole in the outer wall of the inner pad 210;

[0041] A filter screen 240 is installed in the middle of the inner side of the inner pad 210, and two scrapers 290 are respectively set in the middle of both sides of the filter screen 240.

[0042] The scraper 290 consists of two metal pads and a rubber scraper strip;

[0043] An arc-shaped baffle is provided at the inner end of the anti-overflow ring gasket 260 facing the filter screen 240.

[0044] When the impeller inside the water pump rotates, the external water pipe can actively draw liquid material into the pump. During this process, the liquid material will be filtered by the filter screen 240, and solid lumps or solid impurities in the material can be blocked.

[0045] As liquid material is continuously pumped in, it exerts a lateral thrust on the side-mounted pressure plate 284. Combined with the reverse support of the spring 285, the pull rod 281 will eventually be compressed and extend in a regular manner. Finally, the scraper 290 installed at the inner end of the pull rod 281 can push the impurities blocked on the outside of the filter screen 240 towards the inner wall of the inner pad 210. Combined with the pressure of the material, the impurities can eventually be squeezed out from the groove on the outer wall of the inner pad 210 and enter the inner cavity of the sewage discharge chamber 110. Example 2

[0046] Combination Figure 4 and Figure 5 As shown, based on Embodiment 1, the traction assembly 230 includes a main tube 231 installed in the inner pad 210, a sub-rod 232 movably installed inside the main tube 231, and a tension spring 233 disposed inside the main tube 231.

[0047] The outer end of the sub-rod 232 is mounted on the diverter plate 220.

[0048] Preferably, the main tube 231 is fixed in the hole of the outer wall of the inner pad 210 by welding, and the inner end of the tension spring 233 is fixed on the inner wall of the main tube 231, while the other end of the tension spring 233 is fixed on the end of the sub-rod 232 that penetrates into the inside of the main tube 231. Under constant pressure, the two sets of traction components 230 can press the diverter plate 220 into the groove of the outer wall of the inner pad 210. Example 3

[0049] Combination Figure 4 As shown, in the above embodiment, the liquid booster assembly 280 includes two pull rods 281 movably installed in two third sleeves 270, a pad 282 installed at the outer end of the two pull rods 281, a traction rod 283 installed on the pad 282, a booster inclined plate 284 installed at the inner end of the traction rod 283, and a spring 285 disposed outside the traction rod 283.

[0050] The tow bar 283 has an overall L-shaped structure, and a gasket is installed on the tow bar 283;

[0051] One end of the spring 285 is pressed against the washer, while the other end of the spring 285 is pressed against the second sleeve 150.

[0052] Preferably, the two pull rods 281 are adapted to extend through the outside of the two first sleeves 120. As the pressure boosting plate 284 is continuously pressed, the angle formed between the inner end 140 and the built-in ring washer 250 can work with the spring 285 to provide a reciprocating pushing force to the pressure boosting plate 284. Ultimately, the liquid boosting assembly 280 can drive the two scrapers 290 to vibrate regularly to improve the effective discharge of impurities.

[0053] The working principle and usage process of this utility model are as follows: After the inner end 140 is connected to the water pump, the external water pipe can be connected to the outer end 130. When the water pump draws water from the external water pipe and passes through the liquid inlet mechanism 100, the liquid transferred from the inner cavity of the outer end 130 will pass through the filter screen 240. Solid impurities in the solution will be blocked by the filter screen 240, and the solution will pass through the filter holes of the filter screen 240 and transfer to the inside of the water pump.

[0054] As the solution is continuously input, the solution pressurizes the inclined plate 284 toward the filter screen 240, and with the elastic support of the inner end pad of the traction rod 283 by the spring 285, the pressure plate 284 and the traction rod 283 will reciprocate along the inside of the second sleeve 150, and the outer end of the traction rod 283 will push the pad 282 and the two pull rods 281 to reciprocate and extend.

[0055] As the pull rod 281 extends and reciprocates, the two scrapers 290 installed at the inner ends of the two pull rods 281 will be pressed and vibrate regularly along both sides of the filter screen 240. As the scrapers 290 extend and reciprocate along the inner side of the inner pad 210, the solid impurities blocked by the filter screen 240 will be transferred by the lateral bending direction of the scrapers 290. Combined with the action of water pressure, the multiple diversion plates 220 in the lateral bending direction of the scrapers 290 will unfold outward. At this time, the solid impurities under the action of water pressure can be effectively squeezed out.

[0056] This ensures the cleanliness of the solution entering the pump.

[0057] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
