Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to an impurity crushing device for a sewage lift pump. Background Technology

[0002] Sewage lifting equipment effectively raises sewage from areas far from or below the city's sewage network to the municipal sewage network or outdoor septic tanks. Currently, sewage lifting pumps use three main types of impurity pulverizing devices: 1. Using blades or hammer mills to physically pulverize solid impurities in the sewage. This device is typically installed at the inlet of the sewage lifting pump and effectively reduces the size of impurities, preventing pump blockage. 2. Hydraulic pulverizing device: Utilizes high-pressure water flow generated by a hydraulic system to impact and pulverize impurities in the sewage. This method achieves good pulverizing results without increasing mechanical wear. 3. Electric pulverizing device: Uses an electric motor-driven rotating blade to pulverize impurities in the sewage. This device typically has high efficiency and strong adaptability, capable of handling different types of sewage. 4. Intelligent control system: Modern sewage lifting pump impurity pulverizing devices are equipped with intelligent control systems that can monitor sewage flow, pressure, and impurity content in real time, automatically adjusting pulverizing intensity and operating status to improve processing efficiency. However, existing crushing devices may not completely crush larger or harder impurities, leaving impurities in the wastewater and potentially causing blockages, which can affect the normal lifting and treatment of wastewater. Utility Model Content

[0025] Please see Figure 1 The diagram shown is a structural schematic of the impurity pulverizing device for a sewage lift pump provided in an embodiment of this utility model. This utility model provides an impurity pulverizing device for a sewage lift pump, comprising:

[0026] Collection chamber 1, which is equipped with a level controller for monitoring the level of sewage, is used to collect sewage;

[0027] Water inlet pipe 2 is disposed on the upper part of the receiving chamber 7 and communicates with the receiving chamber. Water inlet valve is provided on the water inlet pipe to control the start and stop of water inlet. Water inlet pipe is used to provide a sewage inflow channel.

[0028] The circulation valve 3 is connected to the collection chamber 1 and the receiving chamber 7, and is used to pump the sewage in the collection chamber to the pulverizing mechanism;

[0029] The crushing mechanism 4 includes a connecting rod 404, a drive motor 401, and crushing blades connected thereto and located in the receiving chamber 7.

[0030] The impurity pulverizing device for the sewage lift pump in this embodiment also includes an electrical control box, which is connected to the level controller, the inlet valve, the circulation valve, the drive motor, and the drain valve respectively. The electrical control box is used to control the drive motor to stop running and the drain valve to close when the level controller detects that the actual liquid level is less than or equal to the minimum liquid level. When the level controller detects that the actual liquid level is greater than the minimum liquid level, it controls the inlet valve to close and the circulation valve, the drive motor, and the drain valve to open. The circulation valve pumps the sewage in the collection chamber to the pulverizing mechanism along the pipeline. The drive motor drives the connecting rod to rotate and drives the transmission shaft to rotate itself to pulverize the impurities. As the liquid level in the pulverizing mechanism rises until it exceeds the filter baffle, the drain valve pumps out the filtered purified water.

[0031] By setting a liquid level controller, the electrical control box automatically starts the pulverizing pump group. By setting a circulation valve, the sewage in the collection chamber flows to the pulverizing mechanism, so that the sewage can be repeatedly pulverized during the treatment process, ensuring that the solid matter in the sewage is fully decomposed. By setting a filter baffle, impurities are confined within the pulverizing mechanism and pulverized and cut. The sieve holes set on the filter baffle limit the size of impurity particles in the sewage. Only when the particle size of the impurity particles is smaller than the sieve holes on the filter baffle can they be discharged as the sewage level rises, thus preventing the water pump from clogging.

[0032] Specifically, the crushing mechanism 4 is located on one side of the collection chamber 1.

[0033] Specifically, the collection chamber 1 has a wedge-shaped structure.

[0034] In this embodiment, the wedge structure reduces the resistance of water flow, making it easier for solid materials to move along the inclined plane to the crushing mechanism. Therefore, by setting the collection chamber as a wedge structure, it is beneficial to guide solid materials in the sewage to the crushing mechanism. Moreover, the wedge structure of the crushing mechanism helps to reduce dead corners and prevent solid materials from accumulating inside the crushing mechanism, thereby improving the overall treatment efficiency.

[0035] Specifically, the crushing mechanism 4 further includes a rotary bearing 403 and a drive shaft 406 equipped with a universal coupling 405. The drive shaft 406 is equipped with crushing blades 402 and one end is connected to a connecting rod 404. The connecting rod 404 is used to drive the drive shaft 406 to rotate. The rotary bearing 403 is used to support the rotation of the connecting rod 404. The universal coupling 405 is used to make the drive shaft 406 rotate along its own central axis.

[0036] In this embodiment, a universal coupling and a connecting rod are installed. The drive motor drives the connecting rod to rotate, and the connecting rod drives the transmission shaft to rotate through an eccentric circular hole. By installing the universal coupling, the transmission shaft can swing 360°, allowing it to rotate along its own central axis. This causes the crushing blades at different positions to rotate at different radii, resulting in different working ranges and forces for the blades. These forces decrease sequentially towards the universal coupling. Since the crushing blades further away from the universal coupling have a larger rotation range, higher rotation speed, and stronger force, they can more effectively process larger materials. Conversely, the crushing blades closer to the universal coupling have a smaller rotation range, making it easier to crush impurities into more regular shapes. In other words, the blades further away from the universal coupling can better crush the material, while the blades closer to the universal coupling can further refine the already crushed material. The synergistic effect of the different blades allows the material to be processed more evenly during the crushing process, thereby reducing the material's residence time and improving production efficiency.

[0037] Specifically, the number of the crushing blades 402 is set to four, and the crushing blades 402 are inclined around the axis of the drive shaft.

[0038] In this embodiment, by tilting the shredder blade, the chance of the blade contacting the solid material is increased, thereby improving the cutting efficiency and effect. Especially for larger solid materials, the tilt angle is conducive to better cutting. The tilted blade can also reduce the resistance when water flows through, making the water flow smoother and helping to improve the working efficiency of the equipment.

[0039] Specifically, the crushing mechanism 4 is located in the lower half of the receiving cavity.

[0040] Specifically, one end of the circulation valve 3 is connected to the collection chamber, and the other end is connected to the crushing mechanism 4.

[0041] Specifically, a drain valve 6 is provided on one side of the accommodating chamber.

[0042] Specifically, a filter baffle 5 is provided inside the receiving cavity, and the pulverizing mechanism 4 and the drain valve 6 are located on both sides of the filter baffle.

[0043] In this embodiment, by setting a filter baffle, the sieve holes on the filter baffle can effectively block large particles that have not been fully crushed, ensuring that only materials that have reached a certain fineness can pass through. This can prevent these large particles from damaging or clogging the water pump. The filter baffle will also block particles that do not meet the standard, leaving them in the crushing area and continuing to be acted upon by the crushing blades until they are small enough to pass through the sieve holes. The filter baffle starts working when the crushing mechanism is started.

[0044] Specifically, the top of the collection chamber 1 is connected to a vent pipe 101.

[0045] In this embodiment, by setting up a vent pipe, not only can the pressure difference between the collection room and the outside be balanced, preventing problems such as sewage backflow or pump damage caused by pressure difference, but it can also help the gas to be discharged, avoiding equipment instability caused by gas generation during sewage treatment. The vent pipe is designed to be high to ensure that sewage will not overflow even at high water levels. At the same time, the opening of the vent pipe should be far away from the air inlet to prevent pollutants in the outside air from entering the system.

[0046] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
