Description

Technical Field

[0001] The utility model relates to the technical field of sewage pumps, in particular to an anti-clogging sewage pump. Background Art

[0002] Sewage pumps play an irreplaceable role in sewage treatment systems, providing strong guarantees for urban drainage and corporate sewage treatment. As industrial enterprises strive to reduce water consumption per unit of product production, the solid matter and fiber content in sewage is becoming higher and higher. These high-concentration solid matter and fibers are prone to accumulate in the impeller and pipes of sewage pumps, causing blockages, which in turn increases the difficulty and cost of sewage treatment.

[0003] At present, most of the treatment methods for sewage pumps are to install filtering devices at the pump inlet and conduct regular inspections and maintenance. Both the installation of filtering and inspections and maintenance require a lot of cost and effort, but the actual working environment may be deeper. Such a pressure difference puts a greater test on the water pump itself. If solid matter and fiber dirt are added, the water pumping efficiency of the water pump will be reduced. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model is implemented as follows: a blockage-proof sewage pump is constructed, including a motor, a pump body and an outlet pipe, the transmission shaft end of the motor is provided with a sealing cover and a sealing flange, wherein the motor is connected to the pump body through the sealing flange, the pump body is composed of a pump casing, a pump blade structure and a suction port, the outlet pipe is connected to one side of the pump casing, the suction port is opened at the bottom of the pump casing, the pump blade structure is installed in the pump casing and is connected to the transmission shaft of the motor; a piston cylinder is provided on one side of the top of the pump casing, a boosting mechanism is provided in the piston cylinder, a hydraulic controller is provided on the top of the motor, and the output end of the hydraulic controller is connected to the boosting mechanism, and the piston cylinder, the suction port and the outlet pipe are all connected and fixed to the pump casing.

[0005] Furthermore, the boosting mechanism is composed of a waterproof cylinder, a hydraulic rod, a push rod and a piston. The waterproof cylinder surrounds the hydraulic rod and is connected to the end of the piston cylinder. The push rod is connected to the piston and placed in the piston cylinder. At the same time, the tail of the push rod is connected to the hydraulic rod through a sealing ring.

[0006] Furthermore, the pump blade structure mainly includes an impeller and wheel ribs formed at the bottom of the impeller by forging. There is an axial hole at the center of the impeller, and the impeller is coaxially connected to the motor drive shaft through the axial hole.

[0007] Furthermore, evenly distributed arc grooves are provided at the edge of the bottom side of the pump casing connected to the suction port.

[0008] Furthermore, the wheel ribs are irregularly and evenly distributed, and a tooth opening is provided on one side of the edge of any wheel rib.

[0009] Furthermore, a filter is embedded in the inner side of the suction port.

[0010] Furthermore, a lifting frame is connected to one side of the sealing flange.

[0011] The beneficial effects of the utility model can be reflected in the following aspects after specific analysis:

[0012] Advantage 1: The booster mechanism pulls the push rod through the hydraulic rod to move the piston upward and the pressure at the top of the pump casing changes, thereby sucking in excess solid matter and fiber on the impeller, reducing the working pressure of the impeller, thereby ensuring the service life of the impeller and facilitating maintenance by staff.

[0013] Advantage 2: Impurities or fibers are separated and cut through the arc grooves, and then processed through the improved impeller. The ribs on the impeller protrude outwards and the teeth on its edge can ensure that the solid matter is broken and the fibers are cut, thereby increasing the capacity per unit volume and reducing the impact of the pressure difference on the water pump to a certain extent.

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings, and the technical solutions in the embodiments of the present invention will be described clearly and completely, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work shall fall within the scope of protection of the present invention;

[0020] It should be understood that ordinal numbers and directional descriptions, such as "first", "second", "third", "upper, lower, left, right", etc., are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. At the same time, in the description of the present utility model, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and therefore cannot be understood as a limitation on the present utility model.

[0021] The technical solution of the utility model is further elaborated in detail below in combination with the drawings and specific embodiments of the specification. The present application provides an anti-clogging sewage pump, including a motor 1, a pump body 2 and an outlet pipe 4. The transmission shaft end of the motor 1 has a sealing cover 12 and a sealing flange 13, wherein the motor 1 is connected to the pump body 2 through the sealing flange 13, and the pump body 2 is composed of a pump housing 21, a pump blade structure 22 and a suction port 23. The outlet pipe 4 is connected to one side of the pump housing 21, and is used to lift the sewage in the pump housing 21 to the outside. The suction port 23 is opened at the bottom of the pump housing 21, and the sewage is drawn into the pump housing 21 through the bottom of the suction port 23. The pump blade structure 22 is installed in the pump housing 21 and is connected to the transmission shaft of the motor 1; a piston cylinder 212 is provided on one side of the top of the pump housing 21, and a boosting mechanism 3 is provided in the piston cylinder 212. A hydraulic controller 11 is provided at the top of the motor 1, and the output end of the hydraulic controller 11 is connected to the boosting mechanism 3. The piston cylinder 212, the suction port 23 and the outlet pipe 4 are all connected and fixed to the pump housing 21.

[0022] Based on the above supplements, the motor 1 is connected to the pump blade structure 22 through the transmission shaft. The inner bottom of the improved pump housing 21 has a sharp arc groove 211, which can effectively cut and divert solid matter and fibers. The pump blade structure 22 and the booster mechanism 3 greatly improve the pumping efficiency. The sealing cover 12 and the sealing flange 13 ensure the stability and sealing of the motor 1 transmission shaft. The hydraulic controller 11 and the motor 1 itself also adopt waterproof measures. The hydraulic controller 11 keeps the hydraulic rod 32 working through the hydraulic pipe.

[0023] Please refer to Figure 1 , 4As shown, the boosting mechanism 3 is composed of a waterproof cylinder 31, a hydraulic rod 32, a push rod 33 and a piston 34. The waterproof cylinder 31 surrounds the hydraulic rod 32 and is connected to the end of the piston cylinder 212. The push rod 33 is connected to the piston 34 and is placed in the piston cylinder 212. At the same time, the tail of the push rod 33 is kept connected to the hydraulic rod 32 through a sealing ring.

[0024] As an example, it should be noted that the purpose of setting the boosting mechanism 3 is to temporarily suck the solid matter and fibers in the pump casing 21 so that they can be temporarily separated from the impeller 221, thereby reducing the working pressure of the impeller 221, making it easier for the impeller 221 to continuously cut the solid matter and fibers. When operating on deep sewage or with a lot of impurities, the push rod 33 is pulled by the hydraulic rod 32 to move the piston 34 upward and the pressure at the top of the pump casing 21 changes, thereby sucking in excess solid matter and fibers on the impeller 221, reducing the working pressure of the impeller 221, thereby ensuring the service life of the impeller 221 and facilitating maintenance by the staff.

[0025] Please also read Figure 2-3 As shown, the pump blade structure 22 mainly includes an impeller 221 and a wheel rib 222 formed at the bottom of the impeller 221 by forging. An axial hole 224 is provided at the center of the impeller 221, and the impeller 221 is coaxially connected with the drive shaft of the motor 1 through the axial hole 224; the wheel ribs 222 are irregularly and evenly distributed, and a tooth opening 223 is provided on one side of the edge of any wheel rib 222; the wheel rib 222 protrudes outward and the tooth opening 223 on its edge can ensure that solid matter is broken and fibrous matter is cut, thereby increasing the capacity per unit volume.

[0026] At the same time, evenly distributed arc groove pieces 211 are provided at the edge position where the bottom side of the pump housing 21 is connected to the suction port 23. A detachable filter screen 231 is embedded in the inner side of the suction port 23. The arc groove piece 211 is relatively sharp and maintains a smooth connection with the inner side of the suction port 23. That is, the sewage and impurities sucked into the suction port 23 are filtered through the filter screen 231 at the first time. Even if a small amount of impurities or fibers are sucked in, they can be separated and cut by the arc groove piece 211 and finally processed by the pump blade structure 22.

[0027] Figure 1 In the figure, a lifting frame 14 is connected to one side of the sealing flange 13, and the entire motor 1 and the pump body 2 can be pulled up at any time through the lifting frame 14. After the work is completed, the hydraulic controller 11 is used by the control system to push out the hydraulic rod 32, push out the adsorbed fiber material, and replace the filter screen 231 at the same time.

[0028] In summary, the anti-clogging sewage pump of the utility model has an improved pump blade structure and a pump body that can handle impurities and fibers. At the same time, a booster mechanism is installed to ensure the working efficiency of the device in deep water areas or complex working areas, and it is convenient for staff to maintain.

[0029] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here; it should be pointed out that for technical personnel in this field, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent; the protection scope required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
