Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a durable water pump for urban wastewater treatment. Background Technology
[0002] Urban sewage refers to domestic sewage from urban residents, as well as sewage discharged from government agencies, schools, hospitals, shopping malls, and various public facilities. The quality and quantity of this sewage vary greatly. Compared to industrial sewage, the concentration of pollutants is lower, but it still needs to be collected and purified.
[0003] When treating sewage, water pumps are needed to collect and transport the sewage. However, urban sewage contains a large amount of garbage, such as leaves and packaging bags. This garbage can enter the inside of the water pump, causing blockage and damage. To address this problem, we propose a durable water pump for urban sewage treatment. Utility Model Content
[0004] The purpose of this invention is to provide a durable water pump for urban sewage treatment to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A durable water pump for urban sewage treatment includes a pump, an inlet housing connected to the outer surface of the pump, four bearings connected to the outer surface of the inlet housing, a cleaning roller connected to the inner ring of every two bearings, a power mechanism connected to the outer surface of the two cleaning rollers, two collection mechanisms connected to the outer surface of the inlet housing, a filter screen connected to the inner sidewall of the inlet housing, and a cleaning mechanism connected to the outer surface of the filter screen.
[0007] In a further embodiment, the power mechanism includes two transmission gears that mesh with each other.
[0008] In a further embodiment, a waterproof shell is connected to the outer surface of the water inlet shell, and a motor is connected inside the waterproof shell. The output end of the motor is connected to the outer surface of one of the transmission gears.
[0009] In a further embodiment, each of the collection mechanisms includes a collection shell, and the outer surface of each collection shell is provided with a water outlet. The outer surface of the water inlet shell is connected to a plurality of collection arc plates.
[0010] In a further embodiment, the cleaning mechanism includes a rotary joint, the outer surface of which is connected to a cleaning nozzle.
[0011] In a further embodiment, the outer surface of the rotary joint is connected to a water inlet pipe, one end of which is connected to the interior of a water pump, and a one-way valve is provided on the outer surface of the water inlet pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This device uses a water pump to draw sewage into a connected pipe. A power mechanism drives two cleaning rollers to rotate in opposite directions. The rotation of the cleaning rollers pushes large debris into the collection mechanisms on both sides, while small debris enters the water inlet casing and is blocked by the filter screen. Some of the water flow in the pipe cleans the filter screen through the cleaning mechanism and pushes the small debris to the perimeter of the filter screen, thereby reducing the amount of debris entering the water pump, reducing the likelihood of water pump blockage, lessening damage to the water pump, and extending the service life of the water pump.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5In this utility model, a durable water pump for urban sewage treatment includes a pump 1. An inlet housing 2 is connected to the outer surface of the pump 1. Four bearings 3 are connected to the outer surface of the inlet housing 2. A cleaning roller 4 is connected to the inner ring of every two bearings 3. A power mechanism 5 is connected to the outer surface of the two cleaning rollers 4. Two collection mechanisms 6 are connected to the outer surface of the inlet housing 2. A filter screen 7 is connected to the inner wall of the inlet housing 2. A cleaning mechanism 8 is connected to the outer surface of the filter screen 7. By connecting the pump 1 to a pipe, sewage is pumped into the connected pipe. The power mechanism 5 drives the two cleaning rollers 4 to rotate in opposite directions. The rotation of the cleaning rollers 4 pushes large debris into the collection mechanisms 6 on both sides, while small debris is blocked by the filter screen 7. Some water flow cleans the filter screen 7 through the cleaning mechanism 8, pushing the debris to the periphery of the filter screen 7, thereby reducing the amount of debris entering the pump 1 and extending the service life of the pump 1.
[0024] The power mechanism 5 includes two transmission gears 501 that mesh with each other. A waterproof shell 502 is connected to the outer surface of the water inlet shell 2. A motor 503 is connected inside the waterproof shell 502. The output end of the motor 503 is connected to the outer surface of one of the transmission gears 501. Each collection mechanism 6 includes a collection shell 601. A water outlet 603 is provided on the outer surface of each collection shell 601. Multiple collection arc plates 602 are connected to the outer surface of the water inlet shell 2. By setting the collection arc plates 602, it is possible to prevent garbage from entering the gap between the water inlet shell 2 and the sweeping roller 4.
[0025] The cleaning mechanism 8 includes a rotary joint 801, with a cleaning nozzle 802 connected to the outer surface of the rotary joint 801 and a water inlet pipe 804 connected to the outer surface of the rotary joint 801. One end of the water inlet pipe 804 is connected to the interior of the water pump 1, and a one-way valve 803 is provided on the outer surface of the water inlet pipe 804. In the pipe connected to the water pump 1, some water will enter the cleaning nozzle 802 through the water inlet pipe 804. Since the cleaning nozzle 802 has a curved and inclined structure, the water will clean the filter screen 7. Under the reaction force of the water flow, the cleaning nozzle 802 will rotate and clean, pushing the debris to the periphery of the filter screen 7. By setting the one-way valve 803, it is prevented that the cleaning cannot be carried out due to backflow of water.
[0026] The working principle of this utility model is as follows:
[0027] When using this device, connect the pipe to the water pump 1, submerge the device in the sewage, turn on the water pump 1 to pump the sewage into the pipe, turn on the motor 503 to drive the transmission gear 501 to rotate, and the transmission gear 501 drives the cleaning roller 4 to rotate. Through the rotation of the cleaning roller 4, large debris will be pushed into the collection shell 601, and small debris will enter the water inlet shell 2 and be blocked by the filter screen 7. Some of the water in the pipe will be sprayed out from the cleaning nozzle 802 through the water inlet pipe 804. Because the cleaning nozzle 802 is curved, under the reaction force of the water flow, the cleaning nozzle 802 will rotate and clean. Small debris will be pushed back to the periphery of the filter screen 7. After the water is pumped out, take out the device, open the collection shell 601 and the water inlet shell 2, and pour out the internal debris.
[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
