Description

Technical Field

[0001] The present application relates to the technical field of impellers, and in particular to a multi-working-mode slurry pump impeller. Background Art

[0002] A slurry pump is a machine that increases the energy of a solid-liquid mixture by centrifugal force (the rotation of the pump's impeller), and converts electrical energy into kinetic energy and potential energy of the medium. The name of the slurry pump is a centrifugal pump classified from the perspective of the conveying medium.

[0003] A centrifugal pump is a type of fluid machine that relies on the centrifugal force exerted by a rotating impeller on a liquid to transfer energy and transport the fluid. One of the core components of a centrifugal pump is the impeller, which converts mechanical energy into kinetic and static pressure energy. The impeller typically consists of one or more curved blades fixed to a shaft. As the impeller rotates, the blades drive the fluid along with it, generating centrifugal force that propels the fluid outward.

[0004] Depending on the working conditions, the required impeller flow channel width is different. Currently, the existing impeller flow channel width is mostly fixed, which has the defect of low applicability. Summary of the Invention

[0005] In order to improve the applicability of the impeller, the present application provides a multi-working condition slurry pump impeller.

[0006] The multi-operating-condition slurry pump impeller provided in this application adopts the following technical solution:

[0007] A multi-working-condition slurry pump impeller, comprising:

[0008] Mobile disk;

[0009] A fixed plate is provided with a through hole, a pitch-adjusting screw is slidably connected in the through hole, one end of the pitch-adjusting screw is threadedly connected to a pitch-adjusting sleeve, the pitch-adjusting sleeve is rotatably connected to the fixed plate, and the other end of the pitch-adjusting screw is fixed to the movable plate;

[0010] The blade part is provided with a plurality of blade parts, and the blade parts are installed on the fixed disk. The movable disk is provided with an embedding groove which is plugged and matched with the blade parts.

[0011] Using the above technical solution, the staff rotates the pitch adjusting sleeve to move the pitch adjusting screw, thereby adjusting the distance between the fixed disk and the movable disk. When the movable disk moves, the blade part slides in the embedded groove, thereby adjusting the flow channel width of the impeller to adapt to different working conditions, thereby improving the applicability of the impeller.

[0012] Optionally, a thickness adjustment component is sleeved on the blade portion, a fixing plate is fixedly connected to the thickness adjustment component, a mounting bolt is connected to the inner thread of the fixing plate, and a mounting groove adapted to the thread of the mounting bolt is opened on the blade portion;

[0013] The thickness adjustment component includes a plurality of assembly blades, and an assembly component for fixing two adjacent assembly blades is provided between the two adjacent assembly blades;

[0014] A matching seat is provided in the embedding groove, and the matching seat is used to adjust the embedding groove to be compatible with the blade part with the thickness adjustment component.

[0015] By adopting the above technical solution, the thickness adjustment component is detachably mounted on the blade portion by installing bolts and fixing plates, thereby adjusting the distance between two adjacent blade portions to meet different working conditions and further improve the applicability of the impeller.

[0018] Using the above technical solution, the staff will put the required number of sockets together to form a matching seat, then pull the first connecting plate out of the first storage cavity through the fastening plate, and then insert the assembled matching seat into the embedding groove. The elasticity of the first return spring will make the fastening plate press the assembled matching seat tightly into the embedding groove, thereby making the embedding groove compatible with the blade part with the thickness adjustment component.

[0019] Optionally, an inserting plate is fixedly connected to one end of the fastening plate away from the first connecting plate;

[0020] The movable plate is provided with a second receiving cavity on the inner wall at the embedding groove, a second connecting plate is slidably connected in the second receiving cavity, a second reset spring for driving the second connecting plate to reset is installed in the second receiving cavity, one end of the second connecting plate extending out of the second receiving cavity is hingedly connected to a limit plate, a torsion spring is installed at the hinge of the second connecting plate and the limit plate, and a slot adapted to be plugged into the plug plate is provided on one side of the limit plate.

[0021] By adopting the above technical solution, after the fastening plate presses the mating seat tightly, the plug-in adapter of the inserting plate and the slot extends the second connecting plate out of the second receiving cavity, and then the elasticity of the torsion spring causes the limiting plate to press the mating seat again, thereby improving the stability of the mating seat in the embedded groove.

[0022] Optionally, a third receiving cavity is formed on the outer wall of the assembled blade, and the assembly component is arranged in the third receiving cavity;

[0023] The assembly component includes a clamping block and a clamping spring. The clamping block is slidably adapted to the third storage cavity. The inner wall of the assembly blade is provided with a clamping groove that is plugged into the clamping block. Both sides of the clamping block are provided with inclined surfaces. The two ends of the clamping spring are respectively fixedly connected to the clamping block and the assembly blade.

[0024] Using this technical solution, when one assembly blade is placed over another, the inclined surface of the clamping block is squeezed to retract the clamping block into the third receiving cavity. When the clamping slot of one assembly blade is aligned with the third receiving cavity of the other assembly blade, the clamping spring releases its elastic force, inserting the clamping block into the clamping slot. This structure simplifies both installation and removal, improving assembly and removal efficiency.

[0025] Optionally, the assembled blade is covered with a cover plate in the third receiving cavity, the cover plate is interference fit with the third receiving cavity, and the cover plate is used to shrink the clamping block into the third receiving cavity and close the third receiving cavity.

[0026] By adopting the above technical solution, the third receiving chamber of the outermost assembled blade is covered by the cover plate, so that the medium is not easy to enter the third receiving chamber when the impeller is working.

[0027] Optionally, a plurality of through slots are formed through the surface of the fixed disk, the number of the through slots is the same as the number of the blade portions and corresponds one to one, a connecting rod is slidably connected in the through slot, a fourth receiving cavity is formed in the side wall of the connecting rod, a connecting pin is slidably connected in the fourth receiving cavity, an inclined surface is formed on one side of the connecting pin, a connecting spring is provided in the fourth receiving cavity, and both ends of the connecting spring are fixedly connected to the connecting pin and the connecting rod respectively;

[0028] The blade portion is provided with a connection cavity adapted to be plugged into the connection rod, and the inner wall of the blade portion at the connection cavity is provided with a connection groove adapted to be plugged into the connection pin;

[0029] A trigger assembly for driving the connecting rod to move and return is arranged in the fixing disk.

[0030] With the above technical solution, the trigger assembly squeezes the connecting rod, inserting it into the connecting cavity until the connecting groove and the fourth receiving cavity align. At this point, the connecting spring inserts the connecting pin into the connecting groove, thereby mounting the blade portion on the fixed disk. When the trigger assembly is not squeezing the connecting rod, the connecting rod is pulled by the trigger assembly, and the inclined surface of the connecting pin retracts the connecting pin into the fourth receiving cavity, thereby removing the blade portion from the fixed disk. With the above structure, the blade portion and the fixed disk are provided with a detachable connection, allowing damaged blade portions to be replaced separately, reducing replacement costs. Furthermore, the blade portion is easily disassembled and assembled, improving blade portion replacement efficiency.

[0031] Optionally, the trigger assembly includes a trigger seat and a return plate. A trigger groove that is adapted to the trigger seat thread is provided in an annular shape on the surface of the fixed disk facing away from the blade portion. The trigger seat is used to squeeze the connecting rod. The return plate is fixedly connected to the connecting rod. A return spring is fixedly connected between the return plate and the fixed disk.

[0032] By adopting the above technical solution, when the trigger seat squeezes the connecting rod, the connecting rod causes the return spring to accumulate elastic potential energy through the return plate. When the trigger seat moves away from the connecting rod, the return spring releases the elastic force through the return plate to return the connecting rod, thereby achieving the effect of automatic return of the connecting rod.

[0033] Optionally, a positioning rod is fixedly connected to the surface of the fixing plate facing the blade portion, and a positioning groove adapted to be plugged into the positioning rod is provided on the surface of the blade portion facing the fixing plate.

[0034] By adopting the above technical solution, the position of the blade portion is determined by plugging and fitting the positioning rod and the positioning groove, so that the connecting cavity and the connecting rod are aligned, further improving the installation efficiency of the blade portion.

[0035] Optionally, the fixed plate is fixedly connected to a limit block in the through hole, and the pitch-adjusting screw is provided with a limit groove that is slidably matched with the limit block.

[0036] By adopting the above technical solution, when the pitch-adjusting screw moves, the limit block slides along the limit groove, so that the limit block makes it difficult for the pitch-adjusting screw to rotate along with the pitch-adjusting sleeve, thereby achieving the effect of limiting the pitch-adjusting screw.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. The operator rotates the pitch adjustment sleeve to move the pitch adjustment screw, thereby adjusting the distance between the fixed plate and the movable plate, thereby adjusting the flow channel width of the impeller. The thickness adjustment assembly is detachably mounted on the blade section using mounting bolts and a fixing plate, thereby adjusting the distance between two adjacent blade sections. This structure allows the impeller to adapt to different working conditions, thereby improving the impeller's applicability.
