[0014] Beneficial Effects

[0015] The present invention provides a new shaft seal structure for a single-shell slurry pump, which has the following beneficial effects compared with the prior art:

[0016] 1. The user fills the shell with cleaning liquid through the injection hole on the shell, so that the liquid level of the cleaning liquid is at the center axis of the shaft, so that the shaft can be cleaned as a whole when it rotates. At the same time, when the shaft rotates, the user can start the motor connected to the shaft, so that the shaft drives the reel fixedly connected thereon to start rotating. At this time, the two reels cooperate with each other to start driving the belt connected to the transmission to start rotating, so that the wiping plate fixedly connected thereon starts to rotate synchronously. At this time, multiple wiping plates start to scrape back and forth on the shaft. At the same time, because the wiping plates are in close contact with the shaft, the shaft can be effectively increased. The scraping effect can prevent small particles of impurities from adhering to the shaft after wetting. At the same time, the scraping plate can also be made of soft silicone material to avoid leaving scratches on the shaft, and at the same time, the combination tightness between the scraping plate and the shaft can be increased; at the same time, the user can start the water pump, so that the water pump starts to suck the cleaning liquid in the shell, so that the cleaning liquid is sucked into the cavity of the shell through the inlet on the lower side of the side wall of the shell, and the cleaning liquid is filtered through the multi-layer filter plate and then discharged from the connecting pipe, and the filtering effect of the connecting pipe should be increased in sequence, so as to realize multi-stage filtration, thereby intercepting small particles of impurities in the cleaning liquid;

[0017] 2. When the shaft rotates, the bevel gear A fixedly connected thereon starts to rotate synchronously, and drives the bevel gear B meshing with the bevel gear A to rotate synchronously. At the same time, the reciprocating screw A fixedly connected at the axis of the bevel gear B starts to rotate synchronously, and drives the sleeve threadedly connected on the reciprocating screw A to start linear reciprocating motion along the limit rod. At this time, the sleeve drives the cotton tube rotatably connected thereon to start lifting and lowering motion at a uniform speed. When the sleeve moves to the end of the reciprocating screw A, the wiper plate starts to contact the cotton tube synchronously. At this time, the motor is started, so that the motor drives the cotton tube fixedly connected to its output shaft to start rotating synchronously, thereby cleaning the wiper plate through the rotation of the cotton tube, thereby scraping the granular impurities wiped off the shaft rod onto the cotton tube. At the same time, when the sleeve moves to the end of the reciprocating screw A, it can continue to rotate in the same direction through the reciprocating screw A, thereby quickly changing the movement direction of the sleeve, so that the cotton tube starts to rise at a uniform speed to avoid getting stuck on the wiper plate and preventing it from continuing to rotate. At the same time, when the cotton tube rotates, the main gear fixedly connected thereon starts to rotate synchronously. The two gears are connected to each other by the gear, and the two gears are connected to each other by the gear, so that the gears on the gear are connected to the gear, and the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, and the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear, so that the gears on the gear are connected to the gear.

[0018] 3. When the shaft rotates, the internal gear fixed on it rotates synchronously. At this time, the internal gear starts to drive the multiple external gears meshing with it to rotate synchronously, and the multiple external gears start to rotate around the internal gear while rotating in cooperation with the gear ring meshing with it. At this time, the connecting rods fixed at the axis of the multiple external gears start to rotate synchronously, and the frame fixed on it rotates synchronously, so that the rubber cylinder starts to wipe the shaft during the rotation of the frame to remove the mud attached to it and prevent a large amount of mud from entering the housing. At the same time, during the revolution of the frame, it can drive the gears to mesh with the gear ring periodically, so that the gears The wheel starts to rotate with the cooperation of the gear ring meshing with it, and drives the reciprocating screw fixedly connected at its axis to start rotating synchronously. At this time, the reciprocating screw starts to drive the rubber cylinder threaded on it to start linear reciprocating motion along the connection between it and the support rod, so that the rubber cylinder starts to wipe the shaft rod in a cycle. At the same time, the user can connect the water pipe to the drain valve to allow water to flow into the water pipe and out of the connector. The rubber cylinder is rinsed and moistened by the nozzle on it when the rubber cylinder moves near it, so that the rubber cylinder wipes the shaft rod in a wet state. At the same time, the shaft can contact with the brush cylinder during rotation, so that impurities on its surface can be brushed off by the brush cylinder. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] The fixed connection referred to in this application refers to a connection in which a part or component is fixed without any relative movement, which can be divided into detachable connection and non-detachable connection.

[0046] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0047] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused.
