Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure pumps, in particular to a high-pressure pump suction component that is easy to use. Background Art

[0002] High-pressure pumps are equipment that provide high-pressure power for high-pressure jetting cement slurry. They are used for strengthening the foundation of buildings, roads, etc. They can also be used for high-pressure water jets to assist in breaking rocks and dropping coal, supplying fluid to underground hydraulic props, pumping high-pressure water for anchored hydraulic expansion metal anchors, and clearing and cleaning large underground pipelines.

[0003] The existing patent CN219366298U high-pressure pump extraction component is provided with a filter disassembly component inside the high-pressure pump water pumping box. When the external high-pressure pump finishes pumping water, the user disassembles the bottom connecting plate and the high-pressure pump water pumping box, and pulls the bottom connecting plate to drive the inner cavity filter screen on the filter screen connecting plate to be pulled out from the high-pressure pump water pumping box, so that the user can better remove the impurities remaining on the inner cavity filter screen, and in the process of pulling the inner cavity filter screen, the side cleaning brush at the end of the inner cavity filter screen can be driven to brush the surface of the filter screen mounting plate, thereby achieving the effect of cleaning the surface of the filter screen mounting plate, keeping the high-pressure pump water pumping box compartment clean and tidy, avoiding the corrosion caused by the retention of impurities in the high-pressure pump water pumping box compartment due to the difficulty in removing the filtered impurities, thereby enabling the high-pressure pump water pumping box and the external high-pressure pump to be used for a long time;

[0004] However, in this patent, since the above-mentioned filter disassembly component is arranged inside the water pumping tank, during use, it is necessary to drain the water in the water tank first and then disassemble it. Although the filter component can realize the disassembly function, the working efficiency is not high. Therefore, the utility model proposes a convenient high-pressure pump extraction component. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a high-pressure pump suction component that is easy to use.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a convenient high-pressure pump suction assembly, comprising a suction sleeve, the bottom of which is threadedly connected to a threaded base, and a limit position assembly is arranged in the suction sleeve;

[0007] The limiting assembly includes a second filter plate, which is arranged on the inner wall of the suction sleeve. The suction sleeve is located above the second filter plate and is rotatably connected to the first filter plate. A sliding ring is arranged on the top of the first filter plate, and the sliding ring is rotatably connected to the top of the inner wall of the suction sleeve. A first spring is arranged between the sliding ring and the first filter plate. A through hole is opened on the first filter plate, and a first limiting hole and a second limiting hole are opened in sequence on the second filter plate.

[0008] As a preferred embodiment, a mounting rod is provided at the bottom of the second filter plate, a cleaning plate is rotatably connected to the mounting rod, a cleaning rod is provided on the top of the cleaning plate, a second spring is sleeved on the mounting rod, and the top of the second spring is in contact with the bottom of the cleaning plate.

[0009] The beneficial effect of adopting the above further scheme is: the blocked first limiting hole and the second limiting hole are unblocked by the cleaning plate, and the cleaning plate is rotated to the blocked limiting hole and pressed to make the cleaning plate fit the second filter plate. At this time, the blocked limiting hole is squeezed to push out the impurities blocked inside, thereby realizing the cleaning function.

[0010] As a preferred implementation, the diameter of the cleaning rod is smaller than the diameter of the second limiting hole, the diameter of the second limiting hole is smaller than the diameter of the first limiting hole, and the diameter of the first limiting hole is equal to the diameter of the through hole.

[0011] The beneficial effect of adopting the above further scheme is that impurities blocked in the first limiting hole or the second limiting hole may be pushed out by the cleaning rod to achieve unblocking, and further, the passing area of ​​the through hole may be increased or decreased by rotating the first limiting hole or the second limiting hole to the bottom of the through hole.

[0012] As a preferred embodiment, the bottom of the threaded base is fixedly connected with a connecting pipe, and a filter element is arranged in the suction sleeve between the threaded base and the cleaning plate.

[0013] The beneficial effect of adopting the above further scheme is that the threaded base and the suction sleeve are detachable structures. During use, the threaded base can be unscrewed to facilitate observation or replacement of its internal structure, and the screened water can be further filtered through the filter element.

[0014] As a preferred implementation, a pull rod is provided at the top center of the first filter plate, the first springs are distributed in a ring shape, and the angles between two adjacent first springs are equal.

[0015] The beneficial effect of adopting the above further scheme is: the first filter plate is driven to move upward by the pull rod. When the first filter plate moves upward, the first spring contracts after being subjected to force. When the pull rod is released, the first filter plate is squeezed downward under the action of the first spring, so that the first filter plate and the second filter plate are fitted together to prevent water from flowing in from the gap between them.

[0016] As a preferred implementation, a clamping rod is provided at the top center of the second filter plate, a clamping groove is provided at the bottom of the first filter plate, and the clamping rod and the clamping groove are clamped with each other.

[0017] The beneficial effect of adopting the above further scheme is: the first filter plate and the second filter plate are limited by the mutual clamping and fixing between the clamping rod and the clamping groove, so as to prevent the first filter plate from rotating on the second filter plate during use, causing the through hole and the first limiting hole or the second limiting hole to be misaligned and closed, resulting in the inability to perform the extraction work.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] 1. In the utility model, the first filter plate is moved upward by pulling the pull rod upward, so that the clamping rod is pulled out of the clamping groove. At this time, the first filter plate is rotated as needed, and the first limiting hole or the second limiting hole is rotated to below the through hole, so that the through hole is aligned with the first limiting hole or the second limiting hole. After the alignment is completed, the pull rod is released, and under the action of the first spring, the first filter plate is driven to be squeezed downward, so that the first filter plate overlaps with the second filter plate. By rotating the through hole to above different limiting holes, the passing area of ​​the through hole is changed, thereby blocking impurities of different sizes as needed, thereby improving the practicality of the device.

[0020] 2. In the utility model, the suction sleeve and the threaded base are a split structure. The advantage of the split structure is that the threaded base can be removed from the bottom thread of the suction sleeve and the internal filter element can be replaced. While facilitating the replacement of the clean filter element, the cleaning plate can be pulled downward and rotated to the blockage of the second filter plate. After loosening the cleaning plate, the garbage in the blocked limit hole can be pushed out under the action of the second spring to achieve a cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example 1

[0031] like Figure 1-6 As shown, the utility model provides a technical solution: a high-pressure pump suction assembly that is easy to use, comprising a suction sleeve 1, the bottom of the suction sleeve 1 is threadedly connected to a threaded base 11, and a limit position assembly 2 is arranged in the suction sleeve 1;

[0032] The limiting assembly 2 includes a second filter plate 22, which is arranged on the inner wall of the suction sleeve 1. The suction sleeve 1 is located above the second filter plate 22 and is rotatably connected to the first filter plate 21. A sliding ring 212 is arranged on the top of the first filter plate 21. The sliding ring 212 is rotatably connected to the top of the inner wall of the suction sleeve 1. A first spring 211 is arranged between the sliding ring 212 and the first filter plate 21. A through hole 214 is opened on the first filter plate 21, and a first limiting hole 221 and a second limiting hole 222 are opened in sequence on the second filter plate 22.

[0033] A mounting rod 23 is provided at the bottom of the second filter plate 22, and a cleaning plate 3 is rotatably connected to the mounting rod 23. A cleaning rod 31 is provided on the top of the cleaning plate 3. A second spring 32 is sleeved on the mounting rod 23. The top of the second spring 32 contacts the bottom of the cleaning plate 3, and the blocked first limiting hole 221 and the second limiting hole 222 are cleared by the cleaning plate 3. The cleaning plate 3 is rotated to the blocked limiting hole and the cleaning plate 3 is pressed to make the cleaning plate 3 fit the second filter plate 22. At this time, the blocked limiting hole is squeezed to push out the impurities blocked inside, thereby realizing the cleaning function.

[0034] Example 2

[0035] like Figure 3 - Figure 6 As shown, the diameter of the cleaning rod 31 is smaller than the diameter of the second limiting hole 222, the diameter of the second limiting hole 222 is smaller than the diameter of the first limiting hole 221, and the diameter of the first limiting hole 221 is equal to the diameter of the through hole 214. The cleaning rod 31 may push out impurities blocked in the first limiting hole 221 or the second limiting hole 222 to achieve dredging. Further, by rotating the first limiting hole 221 or the second limiting hole 222 to the bottom of the through hole 214, the passing area of ​​the through hole 214 is increased or decreased.

[0036] like Figure 1 - Figure 2 As shown, the bottom of the threaded base 11 is fixedly connected with a connecting pipe 12, and a filter element 13 is arranged in the suction sleeve 1 between the threaded base 11 and the cleaning plate 3. The threaded base 11 and the suction sleeve 1 are detachable structures. During use, the threaded base 11 can be unscrewed to observe or replace its internal structure, and the screened water can be further filtered through the filter element 13.

[0037] like Figure 1 , Figure 3 - Figure 6 As shown, a pull rod 213 is provided at the top center of the first filter plate 21, the first springs 211 are distributed in a ring shape, and the angles between two adjacent first springs 211 are equal. The first filter plate 21 is driven to move upward by the pull rod 213. When the first filter plate 21 moves upward, the first spring 211 contracts after being stressed. When the pull rod 213 is released, the first filter plate 21 is pressed downward under the action of the first spring 211, so that the first filter plate 21 and the second filter plate 22 are fitted together to prevent water from flowing in from the gap therebetween.

[0038] A clamping rod is provided at the top center of the second filter plate 22, and a clamping groove is provided at the bottom of the first filter plate 21. The clamping rod and the clamping groove are clamped together. The clamping rod and the clamping groove are clamped together and fixed to each other to limit the first filter plate 21 and the second filter plate 22 to prevent the first filter plate 21 from rotating on the second filter plate 22 during use, causing the through hole 214 and the first limiting hole 221 or the second limiting hole 222 to be misaligned and closed, resulting in the inability to perform the extraction work.

[0039] Working principle:

[0040] like Figure 1-6 As shown, the filter element 13 is inserted into the threaded base 11, and the threaded base 11 is screwed on, so that the threaded base 11 is threadedly connected to the suction sleeve 1, and the other end of the connecting pipe 12 is further fixedly connected to the input end of the high-pressure pump. After the installation is completed, the passing space of the through hole 214 can be changed as needed, and the first filter plate 21 is displaced outward by pulling the pull rod 213, and the first filter plate 21 is rotated so that the sliding ring 212 is slidably connected to the top of the inner wall of the suction sleeve 1, and the first filter plate 21 is slid to above the through hole 214 and the first limiting hole 221 or the second limiting hole 222, thereby changing the passing space of the pull rod 213. After the adjustment is completed, the suction sleeve 1 is placed in the specified position, the high-pressure pump is turned on, and the water source is pumped. During the pumping process, under the action of the through hole 214, larger impurities are prevented from entering the interior, and the water source can be further filtered through the filter element 13.
