Description

Technical Field

[0001] This utility model relates to the field of integrated prefabricated pumping station technology, and in particular to a prefabricated pumping station with a crushing mechanism. Background Technology

[0002] A prefabricated pumping station is a modern drainage lifting device that integrates a cylinder, pump, pipeline and control system. It is mainly used for the collection and transportation of sewage and rainwater.

[0003] To address the issue of large solid pollutants clogging the screen and water pump, existing equipment typically incorporates a crushing mechanism inside the inlet pipe. This mechanism uses multiple sets of rotating crushing paddles with fixed angles to break up the pollutants, ensuring smooth transport.

[0004] However, in actual operation, due to the complex and diverse types of sewage entering the system, the fixed-angle pulverizer paddles cannot achieve both efficient pulverization and smooth fluid flow, resulting in poor adaptability to different water qualities, low treatment efficiency, and even problems such as blockage and increased energy consumption. Summary of the Invention

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to propose a prefabricated pump station with a crushing mechanism. By setting a crushing mechanism with an adjustable crushing paddle angle inside the feed pipe, it can be adjusted according to the type of sewage impurities, significantly improving adaptability to different working conditions, achieving a balance between crushing efficiency and flowability, and greatly reducing maintenance requirements.

[0007] To achieve the above objectives, the first aspect of this utility model proposes a prefabricated pump station with a crushing mechanism, comprising: a pump station body and a crushing mechanism, wherein the feed pipe is connected to the front bottom of the pump station body, and the crushing mechanism includes a sleeve, a filter plate, a filter cylinder, two rotating rings, and a crushing assembly, wherein the sleeve is fixedly installed inside the feed pipe, the filter plate is fixedly installed inside the rear side of the sleeve, the filter cylinder is fixedly installed inside the sleeve by multiple connecting rods, and the two rotating rings are rotatably connected to the inner sides of both ends of the filter cylinder, and the inner sides of the two rotating rings are connected by multiple connecting rods. The connecting rod is connected to the rotating tube, and a first driving assembly is installed on the top of the sleeve. The first driving assembly is connected to the rotating ring. The crushing assembly includes a rotating shaft and a plurality of crushing paddles.

The plurality of crushing paddles are respectively rotatably installed on the outside of the rotating tube, and a second bevel gear is fixedly installed at one end of the crushing paddle located inside the rotating tube. A second driving assembly is installed inside the sleeve, and the second driving assembly is connected to the crushing assembly.

[0008] In addition, the prefabricated pumping station with a crushing mechanism proposed above according to this utility model may also have the following additional technical features: Specifically, one of the first bevel gears meshes with a plurality of corresponding second bevel gears.

[0009] Specifically, the second drive assembly includes a connecting pipe, a second motor, and a conductive slip ring. The connecting pipe is fixedly connected to the top end of the inner side of the sleeve, and the bottom of the connecting pipe is rotatably connected to the tail end of the rotating pipe. The second motor is disposed inside the connecting pipe and fixedly connected to the rear end of the rotating pipe. The drive shaft of the second motor is fixedly connected to the rotating shaft.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following describes an embodiment of the present invention, a prefabricated pumping station with a crushing mechanism, with reference to the accompanying drawings.

[0021] like Figures 1-6 As shown, a prefabricated pumping station with a crushing mechanism according to an embodiment of the present invention includes: a pumping station body 1 and a crushing mechanism 3.

[0022] The pump station body 1 has an inlet pipe 2 connected to the front bottom of the main body 1.

[0023] It should be noted that the main body of the pump station 1 is an existing prefabricated pump station, which is equipped with a complete water pump system, valve system and monitoring and control system, and can stably detect and transport sewage.

[0024] It should be noted that feed pipe 2 is the main pipe and is connected to multiple branch pipes. Each branch pipe is connected to a different type of sewage tank, and the types of pollutants that need to be crushed are different in different types of sewage tanks.

[0025] The crushing mechanism 3 includes a sleeve 31, a filter plate 32, a filter cylinder 33, two rotating rings 34, and a crushing assembly 37.

[0026] Among them, the sleeve 31 is fixedly installed inside the feed pipe 2, the filter plate 32 is fixedly installed inside the rear side of the sleeve 31, and the filter cylinder 33 is fixedly installed inside the sleeve 31 by multiple connecting rods.

[0027] Two rotating rings 34 are rotatably connected to the inner sides of both ends of the filter cartridge 33. The inner sides of the two rotating rings 34 are connected to rotating tubes 35 through multiple connecting rods. A first drive assembly 36 is installed on the top of the sleeve 31 and is connected to the rotating rings 34.

[0028] It should be noted that a waterproof and corrosion-resistant mechanical seal is provided at the rotational connection between the rotating ring 34 and the filter cartridge 33.

[0029] It should be noted that the first drive assembly 36 includes a sealing cover, a first motor, two first synchronous pulleys and two second synchronous pulleys. The sealing cover is fixedly installed on the top of the sleeve 31. The first motor is installed inside the sealing cover and is a dual-output shaft motor. The two first synchronous pulleys are respectively fixedly installed on the outside of the drive shafts on both sides of the first motor. The two second synchronous pulleys are respectively fixedly installed on the outside of the two rotating rings 34. A connecting groove is opened on the inner side of the connecting rod between the sleeve 31 and the filter cartridge 33. The synchronous belt passes through the connecting groove and is sleeved on the outside of the first and second synchronous pulleys.

[0030] In addition, it should be noted that the sealing cover penetrates the top of the feed pipe 2 and is fixedly connected to the feed pipe 2 by bolts. The sealing cover is sealed to the feed pipe 2 and the sleeve 31 by applying waterproof and corrosion-resistant epoxy resin. An auxiliary shaft for rotational connection is provided on the inner side of the connecting groove. The auxiliary shaft can limit the position of the timing belt, increase the wrap angle of the timing belt on the first timing pulley and the second timing pulley, and reduce the friction between the timing belt and the connecting groove.

[0031] The crushing assembly 37 includes a rotating shaft 371 and a plurality of crushing paddles 373. The rotating shaft 371 is rotatably mounted inside the rotating tube 35, and a plurality of first bevel gears 372 are fixedly mounted on the outside of the rotating shaft 371. The plurality of crushing paddles 373 are respectively rotatably mounted on the outside of the rotating tube 35, and a second bevel gear is fixedly mounted on one end of the crushing paddle 373 located inside the rotating tube 35. One first bevel gear 372 meshes with a corresponding second bevel gear.

[0032] It should be noted that a waterproof and corrosion-resistant mechanical seal is provided at the rotatable connection between the pulverizer 373 and the rotary tube 35.

[0033] A second drive assembly 38 is installed inside the sleeve 31, and the second drive assembly 38 is connected to the crushing assembly 37.

[0034] It should be noted that a guide plate is installed on the inner front end of the sleeve 31, and a guide angle is provided at the connection between the filter plate 32 and the inner wall of the sleeve 31. Several inclined filter holes pointing to the filter plate 32 are opened on the outer side of the filter cylinder 33.

[0035] Specifically, when crushing solid pollutants in sewage, the first motor needs to be manually started to drive the rotating ring 34 through the synchronous belt to rotate the crushing component 37. Sewage is guided into the filter cartridge 33 by the guide plate, and the solids are cut by the rotating crushing component 37. Then, they enter the main body of the pump station 1 through the filter plate 32.

[0036] Incompletely crushed solids flow back at an angle along the edge of the filter plate 32 to the interlayer between the filter cylinder 33 and the sleeve 31. Some smaller particles return to the filter cylinder 33 through the inclined filter holes on the filter cylinder 33 for further crushing, while larger particles are guided back to the front end of the filter cylinder 33 for recycling via the guide plate.

[0037] When it is necessary to crush pollutants in different types of sewage, the worker can determine the type of sewage based on the branch pipe that has been opened, and then manually control the second drive component 38 to adjust the crushing component 37 to the corresponding gear, that is, adjust the crushing paddle 373 to different tilt angles.

[0038] During the adjustment process, the second drive assembly 38 drives the rotating shaft 371 to rotate the first bevel gear 372 inside the rotating tube 35. The first bevel gear 372 drives the second bevel gear meshing with it to rotate, thereby adjusting the tilt angle of the pulverizing paddle 373. Different gears can produce pulverizing paddles 373 with different tilt angles, pulverizing different types of pollutants, optimizing pulverizing and flow efficiency, and improving the adaptability and processing reliability of the pump station.

[0039] In one embodiment of this utility model, such as Figure 3 As shown, the second drive assembly 38 includes a connecting pipe 381, a second motor 382, ​​and a conductive slip ring 383.

[0040] The connecting pipe 381 is fixedly connected to the top of the inner side of the sleeve 31, and the bottom of the connecting pipe 381 is rotatably connected to the tail end of the rotating pipe 35.

[0041] It should be noted that a waterproof and corrosion-resistant mechanical seal is provided at the rotatable connection between the connecting pipe 381 and the rotating pipe 35.

[0042] The second motor 382 is located inside the connecting pipe 381. The second motor 382 is fixedly connected to the rear end of the rotating pipe 35. The drive shaft of the second motor 382 is fixedly connected to the rotating shaft 371.

[0043] The conductive slip ring 383 is installed inside the connecting pipe 381. The outer ring of the conductive slip ring 383 is fixedly connected to the connecting pipe 381, and the inner ring of the conductive slip ring 383 is fixedly connected to the second motor 382. The outer ring and the inner ring of the conductive slip ring 383 are rotatably connected.

[0044] It should be noted that the outer ring of the conductive slip ring 383 is electrically connected to the external power supply, the outer ring and the inner ring of the conductive slip ring 383 are electrically connected, and the inner ring of the conductive slip ring 383 is electrically connected to the second motor 382. When the rotating shaft 371 drives the second motor 382 and the inner ring of the conductive slip ring 383 to rotate, the external power supply can supply power to the second motor 382 through the outer ring of the conductive slip ring 383 to achieve the adjustment of the crushing component 37.

[0045] In summary, this utility model's prefabricated pump station with a pulverizing mechanism employs an adjustable-angle pulverizing paddle 373, which can be manually adjusted according to the impurities in the sewage, effectively balancing pulverizing efficiency and flow capacity. The combination of overall pulverization and circulating pulverization significantly reduces the risk of clogging. Key components are equipped with mechanical seals and corrosion-resistant measures to ensure long-term reliable operation in harsh environments.
