Description

Technical Field

[0001] This utility model relates to the field of sewage pump technology, specifically a cutting-type anti-clogging sewage pump for sewage systems. Background Technology

[0002] With the accelerating pace of urbanization in China, rural populations are continuously migrating to urban areas, leading to a surge in urban areas and populations, and consequently, a significant increase in wastewater volume. Simultaneously, increased environmental awareness necessitates the centralized treatment of industrial wastewater, domestic sewage, and initial rainwater runoff before discharge. However, wastewater treatment plants are typically located on the outskirts of cities, making gravity flow to these plants difficult; thus, pumping stations are needed for lifting and transporting wastewater. Prefabricated pumping stations, also known as integrated pumping stations, have emerged as a revolutionary solution, effectively meeting new requirements regarding odor, noise, land area, construction period, equipment lifespan, corrosion and seepage resistance, intelligent operation, and overall efficiency. Unlike traditional wastewater collection and transportation systems, prefabricated pumping stations offer integration, intelligence, energy efficiency, durability, corrosion and leakage resistance, and low maintenance costs.

[0003] Wastewater typically contains various scum, plastic products, and other fibers such as cotton yarn, hemp rope, and rags, or similar materials. These impurities can clog the inlet, causing poor wastewater transport, affecting the normal operation of the sewage pump, damaging the motor, and reducing the pump's efficiency. To adapt to the working environment of the sewage system, a cutting-type anti-clogging sewage pump is needed. Utility Model Content

[0004] The purpose of this invention is to provide a cutting-type anti-clogging sewage pump for sewage systems to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting-type anti-clogging sewage pump for a sewage system, comprising a pump body and a lower frame, wherein a water outlet is installed on the right side of the pump body, the lower frame is installed below the pump body, and a mesh is installed inside the side wall of the lower frame, a fixed blade is installed on the upper part of the interior of the lower frame, and serrations are welded to the inner side of the fixed blade, the pump body adopts a stainless steel open impeller or double blade structure, combined with CFD flow field optimization technology, to improve the impurity throughput and reduce the risk of entanglement.

[0006] Furthermore, a carbide blade is mounted below the fixed blade, and the carbide blade and the fixed blade are rotatably connected.

[0007] Furthermore, a support frame is installed on the outer side of the lower frame, and the support frame is slidably connected to the lower frame. The length of the support frame sliding downward is adjusted according to the daily accumulated depth of silt at the bottom of the sewage system, thereby ensuring that the water inlet of the pump body is not blocked by silt.

[0008] Furthermore, a level is installed above the pump body, and a transmitter is installed on one side of the level. If the pump body collapses, the level will send a signal through the transmitter to notify the staff to handle the situation.

[0009] Furthermore, a switch assembly is installed on the left side of the pump body, and the switch assembly is welded to the pump body.

[0010] Furthermore, the switch assembly includes a connecting slide rod, an insulating layer, and a conductive rod. The insulating layer is slidably connected inside the connecting slide rod, and the conductive rod is installed above the inside of the insulating layer. The cavity drives the connecting slide rod to rise, and the connecting slide rod slides from the insulating layer onto the conductive rod, thereby connecting the circuit and starting the pump body to run.

[0011] Furthermore, a cavity is installed around the connecting slide rod, and the cavity is embedded in the connecting slide rod. When the water level in the sewage system rises, the buoyancy of the water pushes the cavity to rise.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the length of the downward sliding of the support frame is adjusted according to the daily accumulated depth of the silt at the bottom of the sewage system, thereby ensuring that the inlet of the pump body is not blocked by silt. If the pump body falls over, the level instrument sends a signal through the transmitter to notify the staff to handle the situation, preventing the pump body from sinking into the bottom silt. When the water level in the sewage system rises, the buoyancy of the water pushes the cavity to rise, and the cavity drives the connecting slide rod to rise. The connecting slide rod slides from the insulating layer to the conductive rod, thereby connecting the circuit and starting the pump body to run. There is no need for manual monitoring of the water level. When the pump body runs, it drives the carbide blade to rotate. The carbide blade and the fixed blade work together to cut long fibers, plastics, cloth strips and solid particles with a diameter exceeding % of the pump inlet diameter. The serrations on the edge of the fixed blade make the cutting effect better. The mesh on the lower frame prevents excessively large debris from blocking the inlet of the pump body and facilitates the output of sewage from the outlet.

[0013] 1. When the pump body of this utility model is running, it drives the carbide blade to rotate. The carbide blade and the fixed blade work together to cut long fibers, plastics, cloth strips and solid particles with a diameter exceeding 50% of the pump inlet diameter. The serrations on the edge of the fixed blade make the cutting effect better. The mesh on the lower frame prevents excessive debris from clogging the pump body's inlet and facilitates the output of sewage from the outlet.

[0014] 2. This utility model adjusts the downward sliding length of the support frame according to the daily accumulated depth of silt at the bottom of the sewage system, thereby ensuring that the pump inlet is not blocked by silt. If the pump body collapses, the level instrument sends a signal through the transmitter to notify the staff to handle the situation, preventing the pump body from sinking into the bottom silt. When the water level in the sewage system rises, the buoyancy of the water pushes the cavity upward, and the cavity drives the connecting slide rod upward. The connecting slide rod slides from the insulation layer to the conductive rod, thereby connecting the circuit and starting the pump body to run, without the need for manual monitoring of the water level.

[0019] like Figure 1 and Figure 2 As shown, a cutting-type anti-clogging sewage pump for a sewage system includes a pump body 1 and a lower frame 3. An outlet 2 is installed on the right side of the pump body 1. The lower frame 3 is installed below the pump body 1, and a mesh 4 is installed inside the side wall of the lower frame 3. A fixed blade 5 is installed on the upper part of the lower frame 3, and serrations 6 are welded to the inner side of the fixed blade 5. A carbide blade 7 is installed below the fixed blade 5, and the carbide blade 7 and the fixed blade 5 are rotatably connected. When the pump body 1 is running, it drives the carbide blade 7 to rotate. The carbide blade 7 and the fixed blade 5 work together to cut long fibers, plastics, cloth strips, and solid particles with a diameter exceeding 50% of the pump inlet diameter. The serrations 6 on the edge of the fixed blade 5 improve the cutting effect. The mesh 4 on the lower frame 3 prevents excessively large debris from clogging the inlet of the pump body 1, and facilitates the output of sewage from the outlet 2.

[0020] like Figure 1 and Figure 3As shown, a support frame 8 is installed on the outer side of the lower frame 3, and the support frame 8 is slidably connected to the lower frame 3. A level 9 is installed above the pump body 1, and a transmitter 10 is installed on one side of the level 9. A switch assembly 12 is installed on the left side of the pump body 1, and the switch assembly 12 is welded to the pump body 1. The switch assembly 12 includes a connecting slide rod 1201, an insulating layer 1202, and a conductive rod 1203. The insulating layer 1202 is slidably connected inside the connecting slide rod 1201, and the conductive rod 1203 is installed above the inside of the insulating layer 1202. A cavity 11 is installed around the connecting slide rod 1201, and the cavity 11 is connected to the connecting slide rod 1201. The connecting slide rod 1201 is an embedded connection. The length of the downward sliding of the support frame 8 is adjusted according to the daily accumulated depth of the silt at the bottom of the sewage system, so as to ensure that the water inlet of the pump body 1 is not blocked by silt. If the pump body 1 falls over, the level 9 sends a signal through the transmitter 10 to notify the staff to handle the situation, so as to prevent the pump body 1 from sinking into the bottom silt. When the water level in the sewage system rises, the buoyancy of the water pushes the cavity 11 to rise. The cavity 11 drives the connecting slide rod 1201 to rise. The connecting slide rod 1201 slides from the insulating layer 1202 to the conductive rod 1203, thereby connecting the circuit and starting the pump body 1 to run, without the need for manual monitoring of the water level.

[0021] Working principle: When using this type of cutting-type anti-clogging sewage pump for sewage systems, firstly, the downward sliding length of the support frame 8 is adjusted according to the daily accumulated depth of silt at the bottom of the sewage system to ensure that the inlet of the pump body 1 is not blocked by silt. If the pump body 1 tilts, the level 9 sends a signal via the transmitter 10 to notify personnel to handle the situation, preventing the pump body 1 from sinking into the bottom silt. When the water level in the sewage system rises, the buoyancy of the water pushes the cavity 11 upward, which in turn drives the connecting slide rod 1201 upward. Rod 1201 slides from the insulating layer 1202 onto the conductive rod 1203, thereby connecting the circuit and starting the pump body 1. No manual monitoring of the water level is required. When the pump body 1 is running, it drives the carbide blade 7 to rotate. The carbide blade 7 and the fixed blade 5 work together to cut long fibers, plastics, cloth strips and solid particles with a diameter exceeding 50% of the pump inlet diameter. The serrations 6 on the edge of the fixed blade 5 make the cutting effect better. The mesh 4 on the lower frame 3 prevents excessively large debris from clogging the inlet of the pump body 1 and facilitates the output of sewage from the outlet 2.
