Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a pretreatment device and treatment method for a wastewater pump. Background Technology

[0002] Sewage pumps belong to the category of centrifugal impurity pumps and come in various forms, such as submersible and dry types. Currently, the most commonly used submersible type is the QW submersible sewage pump, while the most common dry sewage pumps include the W-type horizontal sewage pump and the WL-type vertical sewage pump. They are mainly used to transport urban sewage, feces, or liquids containing solid particles such as fibers and paper scraps. The temperature of the transported medium is typically no higher than 80℃. Because the transported medium contains easily entangled or bundled fibers, the pump's flow channel is prone to clogging. Once clogged, the pump will malfunction, potentially even burning out the motor, resulting in poor sewage discharge and seriously impacting urban life and the environment. Therefore, anti-clogging performance and reliability are crucial factors in evaluating sewage pumps.

[0003] When sewage pumps are in use, the sewage often contains large solid impurities. As the pump blades rotate, these solid impurities collide violently with the pump blades, which can damage the pump blades over time, leading to poor sealing and affecting the normal operation of the sewage pump. Therefore, a pretreatment device and treatment method for sewage pumps are proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a pretreatment device and treatment method for sewage pumps to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] As an optional solution of the pretreatment device and treatment method for a sewage pump described in this invention, the pretreatment device and treatment method for a sewage pump includes a sewage pump and an input pipe. The input end of the sewage pump is connected to the input pipe, the other end of the input pipe is connected to a pretreatment component, the other end of the pretreatment component is fixedly connected to a pushing device, and the other end of the pushing device is connected to a sludge pipe.

[0007] The preprocessing component includes a processing frame, a first motor, and a rotating shaft. One side of the processing frame is connected to the input pipe, and the other end of the processing frame is fixedly connected to the pushing device.

[0008] A first motor is fixedly connected to the upper part of the processing frame. A rotating shaft is fixedly connected to the end of the main shaft of the first motor. A rotating disk is fixedly connected to the other end of the rotating shaft. The outer side of the rotating disk is rotatably connected to the processing frame. A pressing roller is fixedly connected to the bottom of the rotating disk. The bottom of the pressing roller is rotatably connected to the processing frame.

[0009] A drive gear is fixedly connected to the outside of the rotating shaft, and a driven gear meshes with the outside of the drive gear. A rotating rod is fixedly connected inside the driven gear. The bottom of the rotating rod is fixedly connected to the rotating disk, and the top of the rotating rod is rotatably connected to the processing frame.

[0010] The pushing device includes a sludge frame, one side of which is fixedly connected to a pretreatment component, and the other side of which is connected to a sludge pipe. Pushing components are provided on both sides of the sludge pipe. The outer side of the pushing components is fixedly connected to the sludge frame. A push plate is fixedly connected to the free end of the pushing components. A moving plate is fixedly connected to the other end of the push plate. A squeezing plate is fixedly connected to the other end of the moving plate.

[0011] As an optional embodiment of the pretreatment device and treatment method for a sewage pump described in this invention, wherein the outer sides of the driven gears on both sides of the driving gear mesh with other driven gears.

[0012] When sewage pumps are in use, the sewage often contains large solid impurities. As the pump impellers rotate, these impurities constantly collide violently with the pump blades, which over time can damage the impellers, leading to poor sealing and affecting the normal operation of the sewage pump. This device, however, has a treatment frame installed at the front of the sewage pump. When sewage passes through the treatment frame, a first motor starts, driving a rotating shaft. This shaft drives a rotating disc, which in turn drives a bottom roller. The shaft also drives an outer drive gear, which in turn drives an outer driven gear. This allows multiple... As the crushing rollers rotate, larger solid impurities can be crushed by the rollers as sewage passes through the gaps between them. This helps to pre-treat the sewage and ensures the normal operation of the subsequent sewage pumps. In operation, the pusher can move a push plate on one side, which in turn moves a moving plate on the other side. This actively pushes larger impurities in the sewage closer to the crushing rollers, forcing them into contact with the rollers and crushing them through the interaction between them. This setup actively moves larger solid impurities, preventing their accumulation and facilitating timely treatment.

[0013] As an optional embodiment of the pretreatment device and treatment method for a sewage pump described in this invention, a sealing plate is fixedly connected inside the treatment frame, and the inside of the sealing plate is rotatably connected to the rotating disk.

[0014] A sealing plate is installed above the treatment frame to prevent sewage from flowing upwards and to ensure that the sewage is properly pumped out and used by the sewage pump.

[0015] As an optional embodiment of the pretreatment device and treatment method for a sewage pump described in this invention, the sludge frame is internally connected to a connecting pipe, one side of the connecting pipe is connected to a sludge pipe, and the outer side of the connecting pipe is slidably connected to a moving plate and a squeezing plate.

[0016] This setup ensures that when sewage is pumped out, the sewage is positioned normally on one side of the extrusion plate, and under the action of the extrusion plate, larger impurities in the sewage are promptly pushed to the outside of the crushing roller. The rotation of the crushing roller then crushes the larger solid impurities in the gap.

[0017] As an optional embodiment of the pretreatment device and treatment method for a sewage pump described in this invention, the extrusion plate is formed by connecting multiple semi-cylinders together.

[0018] This setup ensures that as the extrusion plate moves, it squeezes larger solid impurities in the sewage into the gap between the crushing rollers, thus stabilizing the processing of solid impurities. Furthermore, the crushing rollers rotate relative to each other in different directions, so only the crushing roller rotating towards the sewage pump can perform the crushing work.

[0019] As an optional embodiment of the pretreatment device and treatment method for a sewage pump described in this invention, the pushing assembly includes a sealing frame and a second motor. One side of the sealing frame is fixedly connected to a sludge frame. The second motor is fixedly connected inside the sealing frame. The free end of the second motor is fixedly connected to a threaded shaft. A threaded sleeve is helically connected to the outside of the threaded shaft. A sealing sleeve is slidably connected to the outside of the threaded sleeve. One end of the sealing sleeve is slidably connected to the sludge frame, and the other end of the threaded sleeve is fixedly connected to a push plate.

[0020] When the moving plate moves, the second motor is started to drive the threaded shaft to rotate, which in turn moves the threaded sleeve, thereby pushing the moving plate to move stably. At the same time, a sealing sleeve is set on the outside of the threaded sleeve to prevent sewage leakage and ensure the overall sealing of the equipment.

[0021] As an optional solution to the pretreatment device and treatment method for a sewage pump described in this invention, the following steps are taken:

[0022] Step 1: Before use, check the equipment to avoid air leakage due to poor sealing;

[0023] Step 2: Start the sewage pump to extract sewage. When the sewage enters the pretreatment component, the pretreatment component will crush and pulverize the solid impurities in the sewage to ensure that the sewage pump can be used normally.

[0024] Step 3: When the pretreatment component processes solid impurities, the solid impurities can be stably squeezed into the pretreatment component for processing by activating the pushing device;

[0025] Step 4: The treated wastewater can be smoothly discharged through the wastewater pump.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] In use, a treatment frame is installed on the front side of the sewage pump. When sewage passes through the treatment frame, the first motor is started to drive the rotating shaft to rotate, which in turn drives the rotating disk to rotate. The rotating disk drives the bottom crushing roller to rotate, and the rotating shaft drives the outer driven gear to rotate. At this time, multiple crushing rollers can rotate. When sewage passes through the gap between the crushing rollers, larger solid impurities can be crushed by the crushing rollers, which helps the sewage pump to work normally.

[0028] Furthermore, during use, the pusher can be activated to move the pusher plate, which in turn moves the moving plate, which in turn moves the squeezing plate. This can push larger impurities in the wastewater closer to the crushing roller, forcing the larger solid impurities to come into contact with the crushing roller and crush them under the action of the crushing roller. This setup can actively push larger solid impurities to move, preventing them from accumulating and helping to treat larger solid impurities in a timely manner.

[0029] When the extrusion plate moves, the outside of its connecting pipe moves with the moving plate and the extrusion plate. This ensures that the sewage inside the sludge pipe can be smoothly discharged to one side of the extrusion plate, which helps the subsequent pushing action of the extrusion plate.

[0030] When the moving plate moves, the second motor is started to drive the threaded shaft to rotate and move the threaded sleeve, thereby pushing the moving plate to move stably. At the same time, a sealing sleeve is set on the outside of the threaded sleeve to prevent sewage leakage and ensure the overall sealing of the equipment. Attached Figure Description

[0045] The usage steps are as follows;

[0046] Step 1: Before use, check the equipment to avoid air leakage due to poor sealing;

[0047] Step 2: Start the sewage pump 1 to extract sewage. When the sewage enters the pretreatment component 3, the pretreatment component 3 is activated. At this time, the solid impurities in the sewage can be crushed and pulverized to ensure that the sewage pump 1 can be used normally.

[0049] Step 4: The treated wastewater can be discharged smoothly through wastewater pump 1.

[0050] When a sewage pump is in use, the sewage often contains large solid impurities. As the pump impeller rotates, these impurities constantly collide violently with the impeller, which over time can damage the impeller, leading to poor sealing and affecting the normal operation of the sewage pump. This device, however, has a treatment frame 301 installed at the front of the sewage pump 1. When sewage passes through the treatment frame 301, the first motor 302 starts, driving the rotating shaft 303 to rotate. The rotating shaft 303 then drives the rotating disk 304 to rotate, which in turn drives the bottom roller 305 to rotate. Furthermore, the rotating shaft 303 drives the outer drive gear 306 to rotate, which in turn drives the outer driven gear 307 to rotate. At this point, [the pump] can... By rotating multiple crushing rollers 305, larger solid impurities can be crushed by the crushing rollers 305 as sewage passes through the gaps between them. This helps to pre-treat the sewage and ensures the normal operation of the subsequent sewage pump 1. In use, the pusher assembly 402 can move a pusher plate 403 on one side, which in turn moves a moving plate 404 on the other side. This actively pushes larger impurities in the sewage closer to the crushing rollers 305, forcing them to come into contact with the rollers. The larger impurities are then crushed by the interaction of the rollers 305. This setup actively moves larger solid impurities, preventing their accumulation and facilitating timely treatment.

[0053] A sealing plate 309 is provided above the treatment frame 301. The sealing plate 309 can prevent sewage from rising and ensure that the sewage can be normally drawn and used by the sewage pump 1.

[0056] This setup ensures that when sewage is pumped out, the sewage is normally located on one side of the extrusion plate 405, and under the action of the extrusion plate 405, larger impurities in the sewage are promptly pushed to the outside of the crushing roller 305. The rotation of the crushing roller 305 crushes and pulverizes the larger solid impurities in the gap.

[0057] Example 4

[0058] This embodiment is an improvement upon embodiment 3. Please refer to [link / reference]. Figure 3 Specifically, the extrusion plate 405 mentioned above is composed of multiple interconnected semi-cylinders.

[0059] This setup ensures that when the extrusion plate 405 moves, it squeezes larger solid impurities in the sewage into the gap of the crushing roller 305 to stabilize the processing of solid impurities. The crushing rollers 305 rotate relative to each other in different directions, so only the crushing roller 305 rotating towards the sewage pump 1 can perform the crushing work.
