Description

Technical Field

[0001] This invention relates to the field of self-priming sewage pump technology, specifically a self-priming discharge pump with a filtration device. Background Technology

[0002] The self-priming non-clogging sewage pump is a novel product developed based on repeated research of similar technologies at home and abroad. It integrates self-priming and non-clogging sewage discharge, adopts an axial backflow external mixing design, and features a unique design for the pump body and impeller flow channel.

[0003] The prior art describes a self-priming sewage pump for easy removal of blockages. This self-priming sewage pump employs an open impeller design and includes an outlet short pipe, an inlet flap valve, and a pump body. Both the outlet short pipe and the inlet flap valve are fixedly connected to the pump body. The axis of the outlet short pipe is perpendicular to the axis of the inlet flap valve. A shaft is installed within the pump body, mounted in a bearing housing with both ends extending out of the bearing housing. An impeller is mounted on one end of the shaft inside the pump body. A left bearing and a right bearing are housed within the bearing housing, through which the shaft passes. A bearing end cover is fixedly installed on the outer end of the bearing housing. A removable discharge port is located at the bottom of the pump for cleaning debris blocking the pump cavity when the pump is clogged.

[0004] However, in current technology, self-priming sewage pumps are used for the discharge of domestic water from power plants. However, due to the large amount of impurities in domestic wastewater, the anti-clogging structure inside the self-priming sewage pump cannot handle a large number of impurities after long-term operation. Therefore, some impurities will get stuck in the sewage pump during discharge, which will damage the internal components of the sewage pump, reduce the efficiency of the sewage pump, or even cause the sewage pump to stop working. Summary of the Invention

[0005] The purpose of this invention is to provide a self-priming discharge pump with a filtration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A self-priming discharge pump with a filtration device includes a mounting frame. A water supply pipe is provided on the outer wall of the mounting frame. A filter assembly for filtering wastewater is located inside the mounting frame. The filter assembly includes a through hole at the top of the mounting frame. An extension plate is provided on the inner wall of the mounting frame. A groove is provided on the inner wall of the extension plate. A signal block is provided on the inner wall of the groove.

A slot and a cavity are provided at the top of the mounting frame. A receiving groove is provided on the inner wall of the mounting frame. A baffle is provided inside the slot. A pull plate and a filter frame are located inside the cavity.

[0008] As a preferred embodiment of the present invention, the water supply pipe at the inlet end of the mounting frame is located at a higher position of the mounting frame, and the water supply pipe at the outlet end is located at a lower position of the mounting frame. The other end of the water supply pipe at the outlet end of the mounting frame is connected to a self-priming sewage pump.

[0009] In a preferred embodiment of the present invention, the extension plate extends from the mounting frame to the outside through the through hole, the signal block is embedded and connected to the inner wall of the slide groove, the slider is a circular structure and is slidably connected to the inner wall of the slide groove through a slide rail, and the slider is in contact with the signal block.

[0010] As a preferred embodiment of the present invention, one end of the fixed shaft is rotatably connected to the side of the slider away from the slide groove via a drive bearing, and the other end of the fixed shaft is coaxially connected to the retrieval frame, and the retrieval frame can extend out of the through hole and move to the outside of the mounting frame.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention.

[0021] Example

[0022] Please see Figure 1-5 This invention provides a technical solution: a self-priming discharge pump with a filtration device, comprising a mounting frame 1, a water supply pipe 101 on the outer wall of the mounting frame 1, and a filtration assembly for filtering sewage inside the mounting frame 1. The filtration assembly includes a through hole 2 at the top of the mounting frame 1, allowing a retrieval frame 5 to extend out of the mounting frame 1. An extension plate 3 is provided on the inner wall of the mounting frame 1, the extension height of which can be adjusted as needed. A groove 301 is provided on the inner wall of the extension plate 3, and a signal block 302 is provided on the inner wall of the groove 301. The signal block 302 is connected to a slider 4 and a fixed shaft 401 via a PLC controller. When the slider 4 slides to contact the signal block 302, the slider 4 is controlled to stop, and the fixed shaft 401 is controlled to rotate, causing the retrieval frame 5 to tilt, emptying the impurities retrieved inside the retrieval frame 5, thereby cleaning the impurities. After cleaning, the fixed shaft 401 is controlled to drive the retrieval frame 5 back to the center, and the slider 4 continues to slide within the groove 301. The mechanism retracts the retrieval frame 5 back into the mounting frame 1, and the ring-shaped design of the chute 301 causes the retrieval frame 5 to rise and retrieve floating impurities from the sewage, repeating the process. A slider 4 is installed inside the chute 301, and a fixed shaft 401 is installed on the side of the slider 4 away from the chute 301 to drive the retrieval frame 5 to rotate, tilt, or return to center. The retrieval frame 5 is installed at the end of the fixed shaft 401 away from the slider 4 to retrieve floating impurities. The top of the mounting frame 1 has a slot 6 and a cavity 7. The inner wall of the mounting frame 1 has a receiving groove 701 for placing the filter frame 801 and filtering and collecting impurities that have sunk to the bottom. A baffle 601 is installed inside the slot 6 to close the water supply channel when the filter frame 801 is removed for cleaning, thus preventing water from carrying impurities out. A pull plate 8 and a filter frame 801 are installed inside the cavity 7. The filter frame 801 is used to collect impurities that have sunk to the bottom.

[0023] However, in current technology, self-priming sewage pumps are used for the discharge of domestic water from power plants. However, due to the large amount of impurities in domestic wastewater, the anti-clogging structure inside the self-priming sewage pump cannot handle a large number of impurities after long-term operation. Therefore, some impurities will get stuck in the sewage pump during discharge, which will damage the internal components of the sewage pump, reduce the efficiency of the sewage pump, or even cause the sewage pump to stop working.

[0024] In this embodiment, all electrical components are controlled by a conventional controller.

[0025] For an example, please refer to... Figure 1-5 The water inlet pipe 101 of the mounting frame 1 is located at a higher position, while the water outlet pipe 101 is located at a lower position. The other end of the water outlet pipe 101 is connected to a self-priming sewage pump. The extension plate 3 extends from the mounting frame 1 to the outside through the through hole 2. The signal block 302 is embedded in the inner wall of the slide groove 301. The slider 4 has a circular structure and is slidably connected to the inner wall of the slide groove 301 via a slide rail. The slider 4 is in contact with the signal block 302. One end of the fixed shaft 401 is connected to the slider 4 away from the slide groove 301 via a drive bearing. One side of the fixed shaft 401 is rotatably connected, and the other end of the fixed shaft 401 is coaxially connected to the retrieval frame 5. The retrieval frame 5 can extend out of the through hole 2 and move to the outside of the mounting frame 1. The inner walls of the slot 6 and the cavity 7 are both provided with sealing strips. The baffle 601 is slidably connected to the inner wall of the slot 6 via a slide rail. The baffle 601 can extend into the water supply channel inside the mounting frame 1. The pull plate 8 is slidably connected to the inner wall of the cavity 7 via a slide rail. The pull plate 8 is connected to the filter frame 801 via bolts. The filter frame 801 can extend into the storage groove 701 and slide in contact with the inner wall of the storage groove 701. In use, the sewage is first transported to the installation frame 1 by the water supply pipe 101. At the same time, the slider 4 is controlled to slide in the trough 301. When the slider 4 slides upward, it drives the retrieval frame 5 to rise synchronously to retrieve the impurities floating on the water surface. When the slider 4 slides to the contact signal block 302, the slider 4 is controlled to stop and the retrieval frame 5 is tilted by controlling the rotation of the fixed shaft 401. The impurities retrieved in the retrieval frame 5 are poured out and cleaned. After cleaning, the fixed shaft 401 is controlled to drive the retrieval frame 5 back to the center and the slider 4 continues to slide in the trough 301 to retract the retrieval frame 5 back into the installation frame 1. The operation is repeated to continuously retrieve and clean the floating impurities. At the same time, the water flows through the water supply channel to the water supply pipe 101 and is transported to the self-priming sewage pump through the water supply pipe 101. While the water is flowing, the sewage will pass through the filter frame 801 in the collection tank 701. The filter frame 801 filters and collects the impurities that have sunk to the bottom of the water. This invention enables filtration of sewage before it enters the self-priming sewage pump, reducing the impurity content in the sewage and protecting the self-priming sewage pump.

[0026] The working process of this invention is as follows: In use, the water supply pipe 101 first transports sewage to the installation frame 1, while the slider 4 is controlled to slide in the trough 301. When the slider 4 slides upward, it drives the retrieval frame 5 to rise synchronously to retrieve impurities floating on the water surface. When the slider 4 slides to the contact signal block 302, the slider 4 is controlled to stop and the retrieval frame 5 tilts as the fixed shaft 401 rotates, emptying the retrieval frame 5 and cleaning the impurities. After cleaning, the fixed shaft 401 is controlled to drive the retrieval frame 5 back to the center and the slider 4 continues to slide in the trough 301, causing the retrieval frame 5 to retract back into the installation frame 1. This process is repeated to continuously retrieve and clean the floating impurities. At the same time, the water flows through the water supply channel to the water supply pipe 101 and is then transported to the self-priming sewage pump. While the water is flowing, the sewage passes through the filter frame 801 in the collection tank 701, which filters and collects the impurities that have sunk to the bottom of the water. This invention enables filtration of sewage before it enters the self-priming sewage pump, reducing the impurity content in the sewage and protecting the self-priming sewage pump.

[0027] 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.
