Description

Technical Field

[0001] This utility model relates to the field of sewage pump technology, specifically a self-priming, non-clogging sewage pump. Background Technology

[0002] A sewage pump is a type of pump that integrates the pump and motor, both of which operate submerged in liquid. Compared to general horizontal or vertical sewage pumps, sewage pumps have the advantages of compact structure and small footprint. They can be directly installed in wastewater tanks without the need for a dedicated pump house, thus reducing construction and maintenance costs. The suction port of traditional sewage pumps is easily blocked by debris, which affects the suction effect. To improve this situation, a self-priming, non-clogging sewage pump has been proposed.

[0003] For example, the direct-drive self-priming non-clogging sewage pump disclosed in the authorization announcement number CN219795585U includes a pump body, a hose sleeve and a rigid pipe flange. The pump body is provided with a self-priming chamber at the bottom, and a base is provided at the bottom of the self-priming chamber. An inlet pipe is provided on one side of the outer ring of the self-priming chamber, and a docking flange is provided at the head of the inlet pipe. The rigid pipe flange is located outside the docking flange. The hose sleeve is located on the outer ring of the docking flange. A hose body is provided outside the hose sleeve. A hose connector is provided at the top of the hose body. A rigid pipe body is provided outside the rigid pipe flange. Additional plates are provided on both sides of the outer ring of the hose sleeve. Horizontal plates are provided at the upper and lower ends of the tail of the additional plates.

[0004] Although it enables quick switching between connecting hoses and rigid pipes by selecting to install a flexible sleeve or rigid pipe flange outside the docking flange of the sewage pump, allowing both hoses and rigid pipes to achieve stable direct connection, the sewage pump can be quickly installed according to the type of pipe connected, thus improving its applicability.

[0005] However, it has not solved the problem that existing sewage pumps are not conducive to convenient multi-position contact with sludge buffering and settling, convenient diversion and sewage discharge, and are not conducive to scraping and cleaning large particles of debris on the surface of the filter cover, thus affecting the flexibility of sewage discharge. Utility Model Content

[0006] The purpose of this utility model is to provide a self-priming, non-clogging sewage pump to solve the problems mentioned in the background art, such as the inconvenience of multi-position contact with silt buffering and settling, convenient diversion and sewage discharge, and the difficulty in scraping and cleaning large particles of debris on the surface of the filter cover, which affects the flexibility of sewage discharge.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-priming, non-clogging sewage pump, comprising a base and a sewage pump body. The sewage pump body is mounted on the top of the base. A suction pipe is mounted on one side of the sewage pump body, and a sewage discharge pipe is mounted on the other side of the sewage pump body. A filter cover is mounted on the end of the suction pipe away from the sewage pump body. Waterproof motors are symmetrically mounted on the outer wall of the suction pipe. Each output end of the waterproof motor is equipped with a drive shaft. An arc-shaped scraper is slidably arranged on the surface of the filter cover, and both ends of the arc-shaped scraper are respectively connected to two sets of drive shafts. A valve body is mounted on the top of the sewage discharge pipe, and two sets of liquid outlet pipes are mounted on the top of the valve body.

[0008] Preferably, the base has four sets of equally spaced support arms inside, and each support arm is equipped with a movable shaft at one end near the base, and the support arm is movably connected to the base through the movable shaft.

[0009] Preferably, the end of the support arm away from the base is equipped with a support leg, and the support leg is slidably connected to the support arm.

[0010] Preferably, the surface of each support leg is fitted with a spring, and the upper and lower ends of the spring are respectively connected to the bearing arm and the support leg.

[0011] Preferably, an electric push rod is movably mounted on the side wall of the valve body, and a push arm is mounted on the output end of the electric push rod.

[0012] Preferably, a connecting arm is installed at the end of the push arm away from the electric push rod, and a pin is installed at the end of the connecting arm near the push arm, and the connecting arm is movably connected to the push arm through the pin.

[0013] Preferably, a hinge shaft is installed at the end of the connecting arm away from the push arm, and the hinge shaft is fixedly connected to the connecting arm.

[0014] Preferably, the hinge shaft extends into the interior of the valve body and is movably connected to the valve body, and a valve plate is provided inside the valve body, with the hinge shaft connected to the valve plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the sewage pump not only realizes convenient multi-position contact sludge buffering and settling and convenient diversion sewage discharge, but also facilitates the scraping and cleaning of large particles of debris on the surface of the filter cover, and improves the flexibility of sewage discharge.

[0016] (1) By rotating the bearing arm, the bearing arm rotates around the movable shaft to rotate the four bearing arms out of the base. Then the sewage pump body is placed inside the sewage tank. During the settling process, the support leg first contacts the sludge. The spring provides elastic support to the support leg, thereby preventing the base from quickly contacting the sludge and settling into the sludge. The sewage pump body sucks the sewage. The sewage enters the inside of the suction pipe through the filter cover. Large particles of debris remain on the surface of the filter cover. In order to avoid the debris from clogging the suction pipe and affecting the suction effect, the waterproof motor drives the drive shaft to rotate. The drive shaft drives the arc scraper to slide on the surface of the filter cover. The arc scraper scrapes and cleans the large particles of debris on the surface of the filter cover to prevent the particles of debris from clogging the suction pipe. This achieves convenient multi-position contact with sludge buffering and settling, and facilitates the scraping and cleaning of large particles of debris on the surface of the filter cover.

[0017] (2) Wastewater enters the valve body through the sewage pump body and sewage pipe, and is discharged from the valve body through two sets of outlet pipes, so that the two sets of pipes can be discharged at the same time. If it is necessary to adjust to discharge sewage through one set of pipes, the electric push rod is opened, the electric push rod drives the push arm to move, the push arm drives the connecting arm to rotate through the pin shaft, and the connecting arm drives the valve plate to rotate through the hinge shaft, so that the valve plate blocks one set of outlet pipes, thereby facilitating the diversion of sewage discharge. At the same time, the other set of pipes can still be used for sewage discharge when the pipe is damaged, realizing convenient diversion of sewage discharge and improving the flexibility of sewage discharge.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5 An embodiment of this utility model provides: a self-priming non-clogging sewage pump, including a base 1 and a sewage pump body 3. The sewage pump body 3 is installed at the top of the base 1. A suction pipe 4 is installed on one side of the sewage pump body 3, and a sewage pipe 5 is installed on the other side of the sewage pump body 3. A filter cover 2 is installed at the end of the suction pipe 4 away from the sewage pump body 3. Waterproof motors 17 are symmetrically installed on the outer wall of the suction pipe 4. The waterproof motors 17 serve as power drives. Drive shafts 18 are installed at the output ends of the waterproof motors 17. An arc-shaped scraper 19 is slidably arranged on the surface of the filter cover 2, and the two ends of the arc-shaped scraper 19 are respectively connected to two sets of drive shafts 18. A valve body 6 is installed at the top of the sewage pipe 5, and two sets of liquid outlet pipes 20 are installed at the top of the valve body 6.

[0026] Rotate the bearing arm 8, which rotates around the movable shaft 7 to rotate the four sets of bearing arms 8 out of the base 1. Then, place the sewage pump body 3 inside the sewage tank. During the settling process, the support leg 9 first contacts the sludge, and the spring 10 provides elastic support for the support leg 9, thereby preventing the base 1 from quickly contacting the sludge and settling into the sludge. Then, turn on the sewage pump body 3 to pump the sewage. The sewage enters the inside of the suction pipe 4 through the filter cover 2. Large particles of debris remain on the surface of the filter cover 2. In order to avoid the debris from clogging the suction pipe and affecting the suction effect, turn on the waterproof motor 17. The waterproof motor 17 drives the drive shaft 18 to rotate, and the drive shaft 18 drives the arc scraper 19 to slide on the surface of the filter cover 2. The arc scraper 19 scrapes and cleans the large particles of debris on the surface of the filter cover 2 to prevent the particles of debris from clogging the suction pipe. This achieves convenient multi-position contact with sludge buffering and settling, and facilitates the scraping and cleaning of large particles of debris on the surface of the filter cover.

[0027] The base 1 has four sets of equally spaced support arms 8 inside. Each support arm 8 has a movable shaft 7 installed at one end near the base 1, and the support arm 8 is movably connected to the base 1 through the movable shaft 7.

[0028] Each end of the support arm 8 away from the base 1 is equipped with a support leg 9, and the support leg 9 is slidably connected to the support arm 8. The surface of the support leg 9 is fitted with a spring 10, and the upper and lower ends of the spring 10 are respectively connected to the support arm 8 and the support leg 9.

[0029] An electric push rod 11 is movably mounted on the side wall of the valve body 6. The electric push rod 11 serves as a power drive. A push arm 12 is mounted on the output end of the electric push rod 11. A connecting arm 14 is mounted on the end of the push arm 12 away from the electric push rod 11. A pin 13 is mounted on the end of the connecting arm 14 close to the push arm 12, and the connecting arm 14 is movably connected to the push arm 12 through the pin 13.

[0030] A hinge shaft 15 is installed at the end of the connecting arm 14 away from the push arm 12, and the hinge shaft 15 is fixedly connected to the connecting arm 14. The hinge shaft 15 extends into the interior of the valve body 6 and is movably connected to the valve body 6. A valve plate 16 is provided inside the valve body 6, and the hinge shaft 15 is connected to the valve plate 16.

[0031] Wastewater enters the valve body 6 through the sewage pump body 3 and sewage pipe 5, and is discharged from the two sets of outlet pipes 20 through the valve body 6, so as to facilitate simultaneous sewage discharge from the two sets of pipes. If it is necessary to adjust to discharge from one set of pipes, the electric push rod 11 is opened, which drives the push arm 12 to move. The push arm 12 drives the connecting arm 14 to rotate through the pin shaft 13. The connecting arm 14 drives the valve plate 16 to rotate through the hinge shaft 15, so that the valve plate 16 blocks one set of outlet pipes 20, thereby facilitating the diversion of sewage discharge. At the same time, the other set of pipes can still be used for sewage discharge when the pipe is damaged, realizing convenient diversion of sewage discharge and improving the flexibility of sewage discharge.

[0032] Working principle: Rotating the support arm 8, which rotates around the movable shaft 7, causes the four sets of support arms 8 to rotate out from inside the base 1. Then, the sewage pump body 3 is placed inside the sewage tank. During settling, the support leg 9 contacts the sludge first, and the spring 10 provides elastic support to the support leg 9, preventing the base 1 from quickly contacting the sludge and settling into it. The sewage pump body 3 then pumps the sewage. The sewage passes through the filter cover 2 and enters the suction pipe 4. Large particles of debris remain on the surface of the filter cover 2. To prevent debris from clogging the suction pipe and affecting the suction effect, the waterproof motor 17 drives the drive shaft 18 to rotate. The drive shaft 18 then drives the arc-shaped scraper 19 to slide on the surface of the filter cover 2. The arc-shaped scraper 19 scrapes and cleans large particles of debris on the surface of the filter cover 2 to prevent them from clogging the suction pipe. Sewage enters the valve body 6 through the sewage pump body 3 and the sewage pipe 5, and is discharged from the two sets of outlet pipes 20 through the valve body 6, so that the two sets of pipes can be discharged at the same time. If it is necessary to adjust to discharge sewage through one set of pipes, the electric push rod 11 drives the push arm 12 to move. The push arm 12 drives the connecting arm 14 to rotate through the pin shaft 13. The connecting arm 14 drives the valve plate 16 to rotate through the hinge shaft 15, so that the valve plate 16 blocks one set of outlet pipes 20, thereby facilitating the diversion of sewage discharge. At the same time, the other set of pipes can still be used for sewage discharge when the pipe is damaged. The above is the complete usage of the self-priming non-clogging sewage pump.
