The pipeline does not need to be installed with a bottom valve, and can be sucked up without water drainage. Different liquids can be made of different materials. The vacuum chamber of the self-priming pump is equipped with a water ring vacuum impeller that is fixed together with the pump cover and the bearing body. Under the rotation of the pump shaft, the air medium and debris in the pipeline can be sucked up and discharged in a few seconds, thereby solving the problem of low suction range of the self-priming pump, easy air intake causing flow loss and low efficiency. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art. Seven blades and a cutting impeller are installed on the inner wall of the pump body. A water ring vacuum impeller is installed in the vacuum chamber and is fixed together with a pump cover and a bearing body. Under the rotation of the pump shaft, the air medium debris in the pipeline can be sucked up and discharged in a few seconds, thereby solving the problems of low suction range, easy blockage, easy entry of air causing flow loss and low efficiency of the self-priming pump.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an energy-saving and non-clogging super-strong self-priming pump, comprising a pump body and a bearing body, a cutting blade is fixedly installed on the inner wall of the pump body, a cutting impeller is arranged on one side of the cutting blade, a vacuum chamber is arranged on one side of the pump body, a vacuum impeller is arranged inside the vacuum chamber, a rear bearing pressure cover is arranged on one side of the bearing body, a front bearing pressure cover is arranged on the other side of the bearing body, a shaft rod is arranged between the inner walls of the front bearing pressure cover and the rear bearing pressure cover, a shaft sleeve is arranged on the outer surface of the shaft rod, two oil seal bearings are arranged on the outer surface of the shaft sleeve, the outer surface of the oil seal bearing is fixedly connected to the inner wall of the bearing body, a mechanical sealing assembly is arranged on the inner wall of the vacuum chamber, two through holes are opened on the outer surface of the mechanical sealing assembly, and a cooling mechanism is connected to one end of the through hole, a suction pipe is fixedly connected to one side of the vacuum chamber, and a valve is arranged on the outer surface of the suction pipe.

[0005] As a preferred embodiment, the cooling mechanism includes a cooling pipeline, and the bottom of the cooling pipeline is fixedly connected with two connecting pipes.

[0006] As a preferred embodiment, one end of the through hole is fixedly connected to a fixed pipe, the outer surface of the fixed pipe is fixedly connected to a clamping pipe, the outer surface of the clamping pipe is provided with a plurality of clamping grooves, and the outer surface of the connecting pipe is slidably connected to the inner wall of the fixed pipe.

[0007] As a preferred implementation, a branch pipe is fixedly connected to the outer surface of the connecting pipe, a rotating pipe is rotatably connected to the outer surface of the branch pipe, and a rubber ring is fixedly connected to the bottom of the branch pipe.

[0008] As a preferred embodiment, a plurality of slide grooves are provided at the bottom of the rotating tube, and support rods are slidably connected to the inner walls of the slide grooves.

[0009] As a preferred implementation, one end of the support rod is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inner wall of the slide groove.

[0010] As a preferred implementation, the other end of the support rod is fixedly connected to a sliding tube, and the inner wall of the sliding tube is fixedly connected to a plurality of clamping blocks.

[0011] As a preferred implementation, the inner wall of the sliding tube is slidably connected to the outer surface of the clamping tube, and the outer surface of the clamping block is slidably connected to the inner wall of the clamping groove.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the present invention, a cutting blade and a cutting impeller are installed on the pump body. When the pump shaft rotates, the cutting impeller is driven to break the imported debris medium when it passes through the cutting device, thereby solving the problem that the self-priming pump is easily blocked, and solving the problem that the self-priming pump inlet has large material impurities causing the pump to be blocked. This self-priming pump solves how to suck up the material medium in a short time without adding a vacuum pump and a control device, and the self-priming height reaches more than 9 meters. This self-priming pump does not need to add a bottom valve and flushing water, and also solves the problem that the dry grinding of the timing seal is easy to break when the pump is started.

[0014] 2. In the present invention, the corresponding cooling water is provided through the cooling pipeline, and the cooling water is circulated and transported through the two connecting pipes, which can not only achieve an effective cooling effect, but also prevent the indiscriminate discharge of the cooling gas. The fixed pipe is connected with the through hole, so that the mechanical seal assembly has a certain lubrication and cooling effect. At the same time, the corresponding cooling mechanism is connected to each other, so that part of the cooling water can be transported to the vacuum chamber, thereby achieving a good condensation effect. The existence of the fixed pipe can make the mechanical seal assembly better connected with the cooling mechanism, which is convenient for removal and installation. The rubber ring can improve the connection between the branch pipe and the fixed pipe. The sealing effect is achieved by inserting the connecting tube into the interior of the fixed tube, and then the top of the fixed tube and the bottom of the branch tube provide tight sealing through the rubber ring to prevent air leakage at the connection. The rotating tube and the sliding tube are connected to each other through the support rod and the spring as supporting members, so that the sliding tube can rotate. At the same time, the spring provides a corresponding elastic force to the support rod. When the block enters the inner wall of the slot, the rotating tube drives the block to enter the lateral inner wall of the slot. At this time, the spring is stretched through the support rod. The elastic potential energy provided by the spring can make the rotating tube always have a force toward the fixed tube, thereby enabling the connection tube and the fixed tube to be sealed.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] According to the above embodiment, the contents in the vacuum chamber can be sucked up by the suction tube 14, and then the suction tube 14 can be closed and opened by the valve. In application, after the contents are sucked out by the suction tube 14, the valve 15 needs to be closed immediately.

[0028] The cooling mechanism 9 includes a cooling pipeline 91, and the bottom of the cooling pipeline 91 is fixedly connected with two connecting pipes 92;

[0029] According to the above embodiment, the corresponding cooling water is provided through the cooling pipeline 91 and circulated and transported through the two connecting pipes 92, which can not only achieve an effective cooling effect, but also prevent the cooling gas from being discharged randomly;

[0030] One end of the through hole is fixedly connected with a fixed pipe 93, the outer surface of the fixed pipe 93 is fixedly connected with a clamping pipe 94, the outer surface of the clamping pipe 94 is provided with a plurality of clamping grooves 95, and the outer surface of the connecting pipe 92 is slidably connected with the inner wall of the fixed pipe 93;

[0031] Through the above embodiment, the fixed pipe 93 is connected with the through hole, so that the mechanical seal assembly 8 has a certain lubrication and cooling effect. At the same time, through the corresponding cooling mechanism 9, part of the cooling water can be transported to the vacuum chamber 5, thereby achieving a good condensation effect. The existence of the fixed pipe 93 can make the mechanical seal assembly 8 better connected with the cooling mechanism 9, which is convenient for removal and installation.

[0032] The outer surface of the connecting pipe 92 is fixedly connected to a branch pipe 96, the outer surface of the branch pipe 96 is rotatably connected to a rotating pipe 97, and the bottom of the branch pipe 96 is fixedly connected to a rubber ring 913;

[0033] According to the above embodiment, the sealing effect between the branch pipe 96 and the fixed pipe 93 can be improved by the rubber ring 913. The connecting pipe 92 is inserted into the fixed pipe 93, and then the top of the fixed pipe 93 and the bottom of the branch pipe 96 are tightly sealed by the rubber ring 913 to prevent air leakage at the connection.

[0034] A plurality of slide grooves 98 are provided at the bottom of the rotating tube 97. A support rod 99 is slidably connected to the inner wall of the slide groove 98. A spring 910 is fixedly connected to one end of the support rod 99. The other end of the spring 910 is fixedly connected to the inner wall of the slide groove 98. A slide tube 911 is fixedly connected to the other end of the support rod 99. A plurality of clamping blocks 912 are fixedly connected to the inner wall of the slide tube 911. The inner wall of the slide tube 911 is slidably connected to the outer surface of the clamping tube 94. The outer surface of the clamping block 912 is slidably connected to the inner wall of the clamping groove 95.

[0035] According to the above embodiment, the support rod 99 and the spring 910 are used as supporting members to connect the rotating tube 97 and the sliding tube 911 to each other, so that the sliding tube 911 can rotate. At the same time, the spring 910 provides a corresponding elastic force to the support rod 99. When the block 912 enters the inner wall of the slot 95, the rotating tube 97 drives the block 912 to enter the lateral inner wall of the slot 95. At this time, the spring 910 is stretched by the support rod 99. The elastic potential energy provided by the spring 910 can make the rotating tube 97 always have a force toward the fixed tube 93, so that the connection tube 92 and the fixed tube 93 can be sealed.

[0036] In this embodiment, the pump body 1 is equipped with a cutting blade 2 and a cutting impeller 3. When the pump shaft rotates, the cutting impeller 3 is driven to break the imported debris medium when it passes through the cutting device, thereby solving the problem that the self-priming pump is easily blocked, and solving the problem that the self-priming pump inlet has large material impurities causing the pump to be blocked. This self-priming pump solves how to suck up the material medium in a short time without adding a vacuum pump and a control device, and the self-priming height reaches more than 9 meters. This self-priming pump does not require a bottom valve and flushing water, and also solves the problem that the dry grinding of the timing seal is easily damaged when the pump is started.

[0037] Working principle:

[0038] like Figure 1-6 As shown, when the block 912 enters the inner wall of the slot 95, the rotating tube 97 drives the block 912 to enter the lateral inner wall of the slot 95. At this time, the spring 910 is stretched by the support rod 99. At the same time, since the block 912 is limited by the slot 95, the block 912 is fixed and cannot move, thereby providing a fixed point so that the slide tube 911 cannot move. At this time, the elastic potential energy provided by the spring 910 can make the rotating tube 97 always have a force toward the fixed tube 93, so that the connecting tube 92 and the fixed tube 93 can be sealed. The cutting blade 2 and the cutting impeller 3 are installed on the pump body 1. When the pump shaft rotates, the cutting impeller 3 can be driven to break the imported debris medium when it passes through the cutting device, thereby solving the problem of easy clogging of the self-priming pump.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
