Description

Technical Field

[0001] This invention belongs to the field of pump technology, specifically relating to a spiral flow slag discharge chamber permanent magnet sewage pump. Background Technology

[0002] In applications such as river dredging and mine drainage, the media typically contain a large amount of solid particles or high concentrations of impurities such as silt. When traditional sewage pumps transport such high-solids media, solid particles can easily enter the impeller area, leading to accelerated wear of critical components such as the impeller, pump casing, and seals, thus affecting the pump's service life and operating efficiency.

[0003] Currently, some sewage pumps use bar screens or filters before the pump for initial interception, but this method is prone to clogging and requires frequent cleaning and maintenance, making it difficult to meet the needs of continuous operation. Other pumps use agitator or cutting devices to break down solids, but these are often complex in structure, energy-intensive, and fail to achieve effective solid-liquid separation; solids still enter the pump body with the liquid, and the wear problem remains unresolved.

[0004] Furthermore, existing sewage pumps often have fixed inlet structures, making it difficult to handle clumps of sludge or large impurities entering the pump. This can easily lead to blockages at the pump inlet, affecting the pump's normal operation. Simultaneously, if solid waste separated from the pump cannot be discharged promptly, it will accumulate inside the pump chamber, further exacerbating blockages and wear.

[0005] Therefore, there is an urgent need to develop a sewage pump structure that can achieve primary solid-liquid separation at the pump inlet, has an automatic slag discharge function, and can effectively prevent inlet blockage, so as to improve the pump's adaptability and service life under ultra-high solid content conditions. Summary of the Invention

The spiral guide arm assembly and the slag-discharge cylinder assembly form a reverse-rotation structure within the sewage pump assembly. Through the rotation of the spiral guide arm assembly within the slag-discharge cylinder assembly, the sewage at the inlet of the sewage pump assembly is spirally and centrifugally guided to the inner wall of the slag-discharge cylinder assembly. Through the rotation of the slag-discharge cylinder assembly within the sewage pump assembly, the spiral centrifugal guidance... The wastewater on the inner wall of the sludge discharge cylinder assembly is centrifuged and separated. At the same time, the spiral guide arm assembly and the sludge discharge cylinder assembly are synchronously reversed within the wastewater pump assembly, so that the sludge between the spiral guide arm assembly and the sludge discharge cylinder assembly is lifted and collected. The bottom of the wastewater pump assembly is rotatably equipped with multiple sets of sludge inlet arm assemblies. When the spiral guide arm assembly rotates, it synchronously drives the multiple sets of sludge inlet arm assemblies to form a synchronous revolution and rotation structure at the bottom of the wastewater pump assembly. Through the synchronous revolution and rotation of the multiple sets of sludge inlet arm assemblies, a sludge-breaking structure that prevents clogging is formed at the inlet of the wastewater pump assembly.

[0049] In this embodiment, the top of the drive boom shaft 201 is rotatably connected to the top of the slag discharge screen cylinder 301 via a bearing.

[0050] In a preferred embodiment, please refer to Figure 9 The sludge inlet arm assembly 400 includes a sludge inlet arm tube 401, a sludge inlet gear 402 is fixedly provided on the outer wall of the top of the sludge inlet arm tube 401, and an agitator arm 403 is fixedly provided on the outer wall of the bottom of the sludge inlet arm tube 401.

[0051] In this embodiment, the sewage inlet arm pipe 401 is rotatably connected to the first rotating disk 110 and the second rotating disk 112 via bearings and shaft groove seats 113.

[0052] In this embodiment, the sewage inlet gear 402 is located between the first rotating disk 110 and the second rotating disk 112.

[0053] In this embodiment, the top of the inlet arm 401 is located between the ring arm 109 and the first rotating disk 110.

[0054] In this embodiment, the stirring arm 403 is located below the second rotating disk 112.

[0055] In this embodiment, the inlet gear 402, the guide gear 208, and the limiting gear ring 111 are on the same horizontal plane.

[0056] In this embodiment, the guide gear 208 is located at the center of a plurality of sewage inlet gears 402, and a limiting toothed ring 111 is provided around the sewage inlet gear 402.

[0057] In this embodiment, the sewage inlet gear 402 is disposed between the guide gear 208 and the limiting gear ring 111, and the two sides of the sewage inlet gear 402 mesh with the guide gear 208 and the limiting gear ring 111 respectively.

[0058] The working principle of this invention is as follows: In river dredging or mine drainage, the solid content of the medium is extremely high. Direct entry into the impeller will accelerate wear. Therefore, it is urgent for the pump to "concentrate" or "pre-separate" the solids to a certain extent. To solve the above problem, the sewage pump assembly 100 of this invention is internally equipped with a spiral guide arm assembly 200, and externally equipped with a slag discharge cylinder assembly 300. Through the rotation of the spiral guide arm assembly 200 within the slag discharge cylinder assembly 300, the sewage at the sewage inlet of the sewage pump assembly 100 is spirally and centrifugally guided to the inner wall of the slag discharge cylinder assembly 300. Through the rotation of the slag discharge cylinder assembly 300 within the sewage pump assembly 100, the sewage spirally and centrifugally guided to the inner wall of the slag discharge cylinder assembly 300 is centrifugally separated and discharged. Specifically, the straight pump casing 101, through the rotation of the spiral pump blade 117, allows the sewage to enter through the inlet arm assembly 400. The wastewater enters the spiral guide arm assembly 200 and the slag discharge cylinder assembly 300 and is discharged from the sewage pipe 118. During this process, when the wastewater enters the spiral guide arm assembly 200, the guide arm 204 throws the wastewater toward the inner wall of the slag discharge cylinder 301 through the guide side groove 207. At the same time, the rotation of the slag discharge cylinder assembly 300 performs primary solid-liquid separation on the wastewater entering the spiral pump blade 117. Through the above structure, primary solid-liquid separation at the pump inlet end is achieved, reducing the wear of the main pump. Meanwhile, the outer wall of the guide arm 204 of this invention is provided with spiral blades 205. The spiral blades 205 form a spiral guide structure between the slag discharge cylinder 301 and the guide arm 204. Through this spiral guide structure, the wastewater thrown out by the spiral guide arm assembly 200 is distributed within this spiral guide structure, avoiding the disorderly distribution of wastewater between the slag discharge cylinder assembly 301 and the spiral guide arm assembly 200.

[0059] Based on the above, in achieving primary solid-liquid separation, rapid discharge of filter residue is essential. Failure to discharge residue promptly will affect the efficiency of the subsequent use of the spiral guide arm assembly 200 and the residue discharge cylinder assembly 300. To address this issue, the spiral guide arm assembly 200 and the residue discharge cylinder assembly 300 of this invention form a reverse-rotation structure within the sewage pump assembly 100. Through the synchronous reverse rotation of the spiral guide arm assembly 200 and the residue discharge cylinder assembly 300 within the sewage pump assembly 100, the sludge between the spiral guide arm assembly 200 and the residue discharge cylinder assembly 300 is lifted and collected. This structure facilitates centralized treatment of the residue and expands the pump's application capability under ultra-high solids content conditions. In actual use, the top of the residue discharge screen cylinder 301 is equipped with a second bevel gear 302, and the top of the drive main arm shaft 201 is equipped with a first bevel gear 202. The first bevel gear 202 is located above the bevel gear 107. Located below the bevel gear 107, the bevel gear 107 meshes with the first bevel gear 202 above and with the second bevel gear 302 below. When the drive main arm shaft 201 rotates through the drive stator 105 and the permanent magnet rotor 203, the drive main arm shaft 201 drives the second bevel gear 302 to rotate through the first bevel gear 202 and the bevel gear 107. Through the above meshing structure, when the spiral guide arm assembly 200 rotates, the slag discharge cylinder assembly 300 rotates synchronously in the opposite direction. That is, the spiral blades 205 on the outer wall of the guide arm 204 scrape the slag on the inner wall of the slag discharge cylinder 301 in the opposite direction and transport it to the slag discharge side trough 303. The slag discharged from the slag discharge side trough 303 falls into the drag ring disk 102. The outer wall of the guide arm 204 of the present invention is provided with multiple spiral blades 205. The spiral blades 205 serve to guide the flow during slag discharge and to scrape and transport the slag after slag discharge.

[0060] Based on the above, the inlet of traditional sewage pumps is fixed. This leads to pressure issues when clumps of sludge enter during water intake, affecting the operation of the spiral guide arm assembly 200 and the sludge discharge cylinder assembly 300. To address this problem, the sewage pump assembly 100 of this invention features multiple sets of sludge inlet arm assemblies 400 rotatably mounted at its bottom. When the spiral guide arm assembly 200 rotates, it synchronously drives these multiple sets of sludge inlet arm assemblies 400 to form a synchronous revolution and rotation structure at the bottom of the sewage pump assembly 100. This synchronous revolution and rotation of the multiple sets of sludge inlet arm assemblies 400 creates an anti-clogging, sludge-breaking structure at the sewage pump assembly 100 inlet. Specifically, when the spiral guide arm assembly 200 rotates, the guide gear 208 at the bottom of the main arm shaft 201 meshes with the sludge inlet gear 402, causing the sludge inlet arm pipe 401 to rotate. The outer side of the inlet gear 402 is meshed on the limiting gear ring 111. When the inlet arm pipe 401 rotates, the inlet gear 402 moves through the meshing on the limiting gear ring 111, causing the inlet arm pipe 401 to rotate on its own axis and revolve around the sun. Through the rotation and revolution of the inlet arm pipe 401, the agitator arm 403 on the inlet arm pipe 401 is driven to rotate, thereby realizing the breaking up of sludge at the bottom inlet of the sewage pump assembly 100. This avoids the operating pressure on the spiral guide arm assembly 200 and the sludge discharge cylinder assembly 300 caused by the entry of clumps of sludge. At the same time, the driving of multiple sets of inlet arm assemblies 400 in this invention is achieved through the synchronous rotation of the spiral guide arm assembly 200. Through the above power structure design, the complexity of the power design of multiple sets of inlet arm assemblies 400 is greatly simplified, and the design of the pump power structure is optimized.

[0061] In another embodiment of the present invention, when the slag is discharged onto the drag ring disc 102, the slag can be promptly cleaned up using an existing external dust collection or screw conveyor structure. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
