Description

Technical Field

[0001] This invention relates to the field of sewage pump technology, specifically to an environmentally friendly anti-clogging sewage pump. Background Technology

[0002] A sewage pump is a centrifugal pump specifically designed to transport liquids (sewage, wastewater, slurry, etc.) containing solid particles, fibers, long strips, and other impurities. Due to the special nature of its working medium and the harsh working environment, sewage pumps employ a variety of key technologies in their design and manufacturing to ensure their reliability.

[0003] Sewage pumps, especially those with large-channel impellers, vortex impellers, or cutters, are designed to handle sewage containing solids, fibers, and other impurities. However, during the transportation process, it is still necessary to intercept some impurities, especially large pieces of plastic sheeting, rags, and other debris mixed in with domestic sewage that can easily become entangled. Although the impeller's surface can cut these debris to some extent, excessive accumulation can still cause entanglement and lead to jamming inside the sewage pump. Existing technologies simply use barriers to intercept sewage, but these require regular cleaning, and mismatched barriers cannot completely prevent such debris from entering the sewage pump. Therefore, we propose an environmentally friendly anti-clogging sewage pump to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide an environmentally friendly, anti-clogging sewage pump to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly anti-clogging sewage pump, comprising,

[0007] The filter tube has an annular inlet ring at its bottom and a suspension ring on its outside. Several pressure plates are located outside the suspension ring, and each pressure plate has a hinged ball with an arc-shaped blade at its bottom. The arc-shaped blades are evenly distributed outside the inlet ring to cut and block long, strip-shaped debris. When sewage needs to be transported, the sewage pump body starts rotating, and the filter tube is placed inside the sewage tank. Under the action of the suspension ring, the filter tube floats on the water surface, and the sewage is simply filtered and transported under negative pressure. This effectively blocks and cuts long, strip-shaped dirt and debris, reducing the risk of impeller entanglement and jamming when transported into the sewage pump body. It also allows excess gas in the sewage to be output through the exhaust pipe, reducing cavitation caused by a large number of air bubbles mixed in with the water entering the sewage pump body.

[0008] Preferably, the top of the inner wall of the filter tube is concave, and the bottom of the connecting tube is provided with a sealing insert. The sealing insert is inserted into the filter tube for drawing out sewage from the bottom. The concave part at the top of the filter tube can form an exhaust chamber. An exhaust pipe is installed at the top of the filter tube to reduce the mixing of air bubbles in the water flow and reduce cavitation in the sewage pump body during transportation. The exhaust chamber structure inside the filter tube works in conjunction with the exhaust pipe to dynamically separate air bubbles in the sewage.

[0009] Preferably, a conveying pipe is provided at the bottom of the filter pipe, a transmission impeller is fixed at the top of the inner wall of the conveying pipe, and a plurality of arc-shaped grooves are opened on the surface of the conveying pipe, and a filter shaft is provided inside the arc-shaped grooves;

A blocking shaft is movably engaged on one side of the fixing frame. The blocking shaft is hollow in an arc shape. An arc-shaped blade can be movably inserted into the blocking shaft. Multiple semi-circular grooves are opened on the outer wall of the blocking shaft. The cutting edge of the arc-shaped blade is serrated. The serrated cutting edge of the arc-shaped blade is movably disposed inside the semi-circular grooves for blocking and cutting the garbage, which can divide long strips of garbage into processable fragments in real time.

[0013] Preferably, one end of the adsorption rod is connected to a threaded tube, the threaded tube has a set of notches, the bottom end of the threaded tube is provided with an elastic plate, and the elastic plate is provided with a set of snap-fit ​​brackets, and several fixing blades are provided between the snap-fit ​​brackets;

[0014] The adsorption rod is internally fitted with a snap-fit ​​rod, and an air pressure ball is installed on the outside of the snap-fit ​​rod. The air pressure ball is squeezed against the suspension ring during the movement. One end of the snap-fit ​​rod is connected to an expansion tube, which is in communication with the air pressure ball.

[0015] Preferably, one end of the expansion tube is provided with a conical extension end, and multiple annular grooves are opened on the conical extension end. A number of adsorption plates are connected to one end of the expansion tube. The adsorption plates are arranged perpendicularly and alternately with the annular grooves.

[0016] Preferably, the bottom of the sewage pump body is connected to a conveying chamber, and a docking plate is installed on the outer wall of the conveying chamber.

[0017] Preferably, the top of the support frame is fixedly connected to multiple welding shafts, which are connected to the bottom of the conveying chamber.

The support frame is equipped with adjustable ground spikes and a counterweight positioning plate, which can achieve rapid installation under different foundation conditions such as silt and concrete.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention uses a dynamic cutting mechanism of suspended ring linked arc blades to divide long strips of waste into processable fragments in real time. Combined with the secondary cutting of fixed blades inside the adsorption rod, a double crushing barrier is formed, which effectively prevents fibers, plastics and other entangled materials from clogging the impeller or pipes.

[0020] 2. This invention, by setting an exhaust mechanism inside the filter tube, can work in conjunction with the exhaust pipe to dynamically separate air bubbles in the sewage, thereby reducing the cavitation rate during liquid transportation.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-8 This invention provides a technical solution: an environmentally friendly anti-clogging sewage pump, comprising,

[0034] The sewage pump body 1 has a support frame 2 installed at the bottom of the sewage pump body 1. A filter pipe 3 is provided between the support frames 2. A connecting pipe 31 is installed at the top of the filter pipe 3. The connecting pipe 31 is located at the water inlet at the bottom of the sewage pump body 1. Several threaded straight pipes are provided on the side wall of the filter pipe 3, and an adsorption rod 4 is inserted into the threaded straight pipe.

[0035] The filter pipe 3 has an annular inlet ring 35 at its bottom and a suspension ring 33 on its outside. Several pressure plates 34 are located outside the suspension ring 33. The bottom of the pressure plate 34 has a hinged ball 39 connected to an arc-shaped blade 391. The arc-shaped blades 391 are evenly distributed outside the inlet ring 35 to cut and block long strips of garbage. When sewage needs to be transported, the sewage pump body 1 can start rotating. At the same time, the filter pipe 3 is placed inside the sewage tank. Under the action of the suspension ring 33, the filter pipe 3 can float on the water surface. Under the negative pressure, the sewage is simply filtered and transported. It can block and cut long strips of dirt and garbage, reducing the situation where the impeller gets tangled and stuck when transported into the sewage pump body 1. It can also output excess gas in the sewage through the exhaust pipe 5, reducing the situation where a large number of air bubbles are mixed in the water flow entering the sewage pump body 1, causing cavitation.

[0036] like Figure 7 As shown, the top of the inner wall of the filter pipe 3 is concave, and the bottom of the connecting pipe 31 is provided with a sealing tube 311. The sealing tube 311 is inserted into the filter pipe 3 for drawing out sewage from the bottom. The concave part at the top of the filter pipe 3 can form an exhaust chamber. An exhaust pipe 5 is installed at the top of the filter pipe 3 to reduce the air bubbles mixed in the water flow and reduce the cavitation formed in the sewage pump body 1 during the transportation process. By inserting the sealing tube 311 into the filter pipe 3, the bottom end of the sealing tube 311 can enter the sewage and discharge the sewage, reducing the air mixing during the transportation process and reducing the air bubbles in the water flow.

[0037] Additionally, it should be noted that the exhaust pipe 5 can work with external air pressure equipment to control the air pressure inside the filter pipe 3, thereby maintaining the liquid level at a fixed height. This reduces the risk of cavitation caused by a large amount of air entering the sewage pump body 1 during subsequent transportation, effectively reducing equipment wear.

[0038] like Figure 5 and Figure 6As shown, a conveying pipe 37 is provided at the bottom of the filter pipe 3, and a transmission impeller 371 is installed at the top of the inner wall of the conveying pipe 37. Several arc-shaped grooves are opened on the surface of the conveying pipe 37, and a filter shaft is provided inside the arc-shaped grooves, which can play a blocking role, blocking some garbage and reducing the blockage caused by large pieces of garbage inside the pipe.

[0039] The sealing tube 311 is connected to the top of the conveying tube 37 to create a negative pressure at the bottom of the sealing tube 311 to filter and convey water along the conveying tube 37. The drive impeller 371 can drive the conveying tube 37 to rotate under the action of the water flow. As the water flow drives the drive impeller 371 to rotate, it can agitate the sewage to flow inside the filter tube 3 and can wrap strip-shaped garbage in the sewage around the outside of the adsorption rod 4 for easy subsequent cleaning and maintenance.

[0040] To reduce the risk of blockage on the outside of the filter pipe 3 at the bottom due to garbage accumulation during sewage transport, a connecting frame 32 is installed at the top of the outer wall of the filter pipe 3. A reset tube 36 is movably attached to the outer end of the connecting frame 32. An extension end is provided at the bottom of the reset tube 36. A suspension ring 33 is installed at the bottom of the extension end. The suspension ring 33 can move outside the filter pipe 3 under the action of buoyancy changes. Under the action of water flow, it can drive the suspension ring 33 to swing up and down, which can collect garbage and dirt on the outside of the suspension ring 33 on the water surface, thus playing a role in interception. Sewage can enter the interior of the filter pipe 3 through the inlet ring 35 at the bottom.

[0041] A water inlet ring 35 has an inlet groove, and a filter plate 351 is installed inside the inlet groove. A fixing bracket 352 is installed at the bottom of the water inlet ring 35. A blocking shaft 38 is movably engaged on one side of the fixing bracket 352. The blocking shaft 38 is hollow in an arc shape. An arc-shaped blade 391 can be movably inserted into the blocking shaft 38. Multiple semi-circular grooves are opened on the outer wall of the blocking shaft 38. The cutting edge of the arc-shaped blade 391 is serrated. The serrated cutting edge of the arc-shaped blade 391 is movably set inside the semi-circular grooves to block and cut the garbage, and the water flows. By changing the buoyancy of the suspension ring 33, the suspension ring 33 can reciprocate under the action of the reset tube 36, which can pull the arc-shaped blade 391 to reciprocate inside the blocking shaft 38, and can cut the external long strips and knots. The spacing and number of arc-shaped blades 391 can be adjusted according to different models, and large pieces of garbage can be cut into smaller pieces of the corresponding size. This can reduce the internal blockage during sewage transportation and also reduce the blockage near the inlet ring 35 caused by excessive accumulation of external garbage.

[0042] like Figure 8As shown, one end of the adsorption rod 4 is connected to a threaded tube 44. The threaded tube 44 has a set of notches. The bottom end of the threaded tube 44 is provided with an elastic plate, and the elastic plate is provided with a set of snap-fit ​​brackets 45. Several fixed blades 451 are provided between the snap-fit ​​brackets 45. With the help of the fixed blades 451, the internal garbage can be further cut and separated, reducing the blockage inside the pipe.

[0043] The adsorption rod 4 has a snap-fit ​​rod 41 inserted inside, and an air pressure ball is installed on the outside of the snap-fit ​​rod 41. The air pressure ball is squeezed by the suspension ring 33 during the movement. One end of the snap-fit ​​rod 41 is connected to an expansion tube 42, which is connected to the air pressure ball. The expansion tube 42 can intercept and treat long strips of dirt in the water flow, which is convenient for subsequent treatment.

[0044] like Figure 8 As shown, one end of the expansion tube 42 is provided with a conical extension end, and multiple annular grooves are opened on the conical extension end. Several adsorption plates 43 are connected to one end of the expansion tube 42. The adsorption plates 43 are arranged perpendicularly and alternately with the annular grooves. The adsorption plates 43 are long rectangular strips and have arc-shaped metal hooks inside, which are used to collect long fibrous impurities in sewage. The sewage, in conjunction with the transmission impeller 371, can drive the conveying pipe 37 to rotate, which can agitate the sewage inside the filter pipe 3 in a circular motion, and can hang the long fibers or plastic materials mixed inside on the adsorption plates 43. With the agitation of the water flow, they can be wrapped around the outside of the expansion tube 42 or further torn under the water flow, which can reduce the operating burden of the sewage pump body 1.

[0045] like Figure 1 As shown, the bottom of the sewage pump body 1 is connected to a conveying chamber 11, and a docking plate 12 is installed on the outer wall of the conveying chamber 11 for connecting with an external conveying pipeline.

[0046] like Figure 1 and Figure 2 As shown, multiple welding shafts 24 are fixedly connected to the top of the support frame 2. The welding shafts 24 are connected to the bottom of the conveying chamber 11. Several hollow tubes 23 are connected to the support frame 2. Ground spikes are inserted inside the hollow tubes 23. A positioning plate 21 is movably inserted inside the support frame 2. A counterweight 22 is provided at the bottom of the positioning plate 21. The positions of the ground spikes and the positioning plate 21 can be adjusted according to the actual use, so that the sewage pump body 1 can be quickly positioned and put into use.

[0047] Working Principle: Firstly, when sewage needs to be transported, the sewage pump body 1 starts rotating. Simultaneously, the filter pipe 3 is placed inside the sewage tank. Under the action of the suspension ring 33, the filter pipe 3 floats on the water surface. Under negative pressure, the sewage is simply filtered and transported. This effectively blocks and cuts long strips of dirt and debris, reducing the likelihood of them being transported into the sewage pump body 1 and causing impeller entanglement or jamming. It also uses the exhaust pipe 5 to output excess gas from the sewage, reducing cavitation caused by a large number of air bubbles mixed in with the water entering the sewage pump body 1. When the filter pipe 3 is placed inside the sewage tank, the negative pressure allows the sewage to flow smoothly... The water is transported to the filter tube 3 through the inlet ring 35. The externally installed blocking shaft 38 can act as a barrier. As the water flow changes the buoyancy on the suspended ring 33, the suspended ring 33 can reciprocate under the action of the reset tube 36. This can pull the arc blade 391 to reciprocate inside the blocking shaft 38, which can cut the long strips and other materials on the outside. The spacing and number of arc blades 391 can be adjusted according to different models, which can cut large pieces of garbage into smaller pieces of the corresponding size. This can reduce the internal blockage during sewage transportation and also reduce the blockage near the inlet ring 35 caused by excessive accumulation of external garbage.

[0048] Then, during the sewage transport process, after the water flows into the filter pipe 3, it can be separated and guided by the filter shaft outside the transport pipe 37. The filtered sewage can be transported to the sewage pump body 1 through the sealed insertion pipe 311. With the help of the sealed insertion pipe 311 extending into the sewage, the entry of air can be effectively reduced. And as the exhaust pipe 5 can be connected to the external air pressure equipment, the air and other air entering the filter pipe 3 can be continuously extracted, so that the liquid level is always higher than the bottom of the sealed insertion pipe 311, which can ensure the stability of sewage transport.

[0049] Finally, the wastewater transmission impeller 371 can drive the conveying pipe 37 to rotate, which can agitate the wastewater inside the filter pipe 3 in a circular motion. This can hang the long strips of fiber or plastic material mixed inside on the adsorption plate 43. With the agitation of the water flow, they can be wrapped around the outside of the expansion pipe 42 or further torn under the water flow, which can reduce the operating burden of the wastewater pump body 1. Moreover, with the movement of the suspension ring 33, it can squeeze the external air pressure ball, which can deform and move the expansion pipe 42, and can intercept and treat some of the internal garbage, reducing the situation where it adheres to the inner wall of the filter pipe 3.

[0050] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
