Description

Technical Field

[0001] The utility model relates to the technical field of circulating pump machines, and particularly relates to a circulating pump machine with a self-filtering structure. Background Art

[0002] A cooling tower is a cooling system used in power plants. In the system, the recycling of cooling water is often achieved through the construction of a circulating water system. The circulating water system realizes the circulation process through a circulating pump machine. As time goes by, debris caused by corrosion in pipeline components, dust impurities and other precipitates will appear in the circulating water pipeline and the suction pool. The precipitates will form larger impurities through aggregation. If these impurities are sucked into the pump machine, they will damage the internal components of the circulating pipe network. Therefore, when the pump machine sucks water flow, a filter screen needs to be added at the front end of the suction pipe to filter impurities. However, long-term filtration will cause the blockage of the filter screen, affecting the flow stability of the circulating water, and disassembling the filter screen for cleaning will bring additional workload.

[0003] In view of this, a design or technical improvement is proposed to solve the above problems.

[0004] The above content is only used to assist in understanding the technical solution of the utility model, and does not represent an admission that the above content is the closest prior art. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above deficiencies and provide a circulating pump machine with a self-filtering structure.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A circulating pump machine with a self-filtering structure includes a pump machine main body, a suction pipe installed on the pump machine main body, and a water outlet pipe communicated with the suction pipe. A bell mouth is arranged at one end of the suction pipe far away from the pump machine main body. A filter cylinder for filtering impurities is arranged in the bell mouth, and a dredging and blocking mechanism for cleaning the filter holes of the filter cylinder is arranged in the filter cylinder. When the pump machine main body pumps and sucks, the dredging and blocking mechanism continuously cleans the filter holes of the filter cylinder.

[0008] Further, the filter holes of the filter cylinder are arranged on the side wall. The dredging and blocking mechanism includes a movable shaft rotatably arranged up and down on the filter cylinder, a connecting plate fixedly arranged on the movable shaft, a cleaning roller rotatably arranged at one end of the connecting plate far away from the movable shaft, and a driving component for driving the movable shaft to rotate. A plurality of groups of spherical convex blocks adapted to the size of the filter holes of the filter cylinder are evenly arranged on the cleaning roller. When the movable shaft rotates, the spherical convex blocks alternately engage with the filter holes of the filter cylinder.

[0009] Further, the upper end of the movable shaft extends through and out of the upper wall of the filter cylinder. The driving component is a spiral fan blade arranged at the upper end of the movable shaft. A connecting cylinder sleeving the outside of the spiral fan blade is arranged on the filter cylinder, and a water passing hole communicating with the connecting cylinder is opened on the filter cylinder. A sealing plate is arranged at the upper end of the flared opening. One end of the connecting cylinder away from the filter cylinder passes through the sealing plate and is communicated with a water suction pipe.

[0010] Further, the lower end of the movable shaft extends through and out of the lower wall of the filter cylinder and is fixedly connected with a centrifugal cylinder, and the inner diameter of the centrifugal cylinder is larger than the outer diameter of the filter cylinder.

[0011] Further, a slag dropping port is opened at the outer edge part of the bottom of the centrifugal cylinder, and a collecting component located below the centrifugal cylinder is detachably connected to the flared opening.

[0012] Further, the collecting component includes a collecting cylinder with water permeable holes opened on the side wall, and a circular hole larger than the outer diameter of the centrifugal cylinder is opened at the upper end of the collecting cylinder.

Bolts are threadedly connected to the connecting arms, and threaded grooves adapted to the bolts are arranged on the side wall of the through groove.

[0014] Compared with the prior art, the beneficial effects of this solution are as follows: By arranging the filter cylinder and the cleaning roller rolling in the filter cylinder, the filter holes of the filter cylinder are circularly dredged and cleaned by the spherical convex blocks on the cleaning roller, so as to ensure that the filter holes will not be blocked during the filtering process, making the circulating water system highly stable and eliminating the need for manual cleaning of the filter cylinder.

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As Figure 1-7 shown, a circulating pump with a self-filtering structure includes a pump body 1, a suction pipe 11 installed on the pump body 1, and a discharge pipe 12 communicated with the suction pipe 11. A bell mouth 2 is provided at one end of the suction pipe 11 far from the pump body 1. A filter cartridge 21 for filtering impurities is arranged in the bell mouth 2. A dredging and blocking mechanism for cleaning the filter holes of the filter cartridge 21 is arranged in the filter cartridge 21; when the pump body 1 pumps and sucks, the dredging and blocking mechanism continuously cleans the filter holes of the filter cartridge 21. When the device is in use, it is installed on the wading pool by hoisting. A part of the pump body 1 is located above the suction pool, and the bottom suction pipe 11 extends into the bottom of the pool. Through the setting of the bell mouth 2, the size of the suction port is enlarged. When the pump body 1 is started, the water body in the suction pool first passes through the filter cartridge 21 in the bell mouth 2 for filtering, so that impurities are blocked on the outer wall of the filter cartridge 21. Due to the suction force, some impurities will get stuck in the filter holes of the filter cartridge 21. At this time, the arranged dredging and blocking mechanism is used to dredge the impurities in the filter holes, so as to ensure the flow-through effect of the filter cartridge 21 and enhance the pumping and sucking stability of the water body.

[0026] In one embodiment, the filter holes of the filter cylinder 21 are provided on the side wall. The clogging prevention and unclogging mechanism includes a movable shaft 3 rotatably arranged up and down on the filter cylinder 21, a connecting plate 31 fixedly arranged on the movable shaft 3, a cleaning roller 32 rotatably arranged at one end of the connecting plate 31 away from the movable shaft 3, and a driving component for driving the rotation of the movable shaft 3; a plurality of spherical bumps 33 adapted to the size of the filter holes of the filter cylinder 21 are evenly arranged on the cleaning roller 32. When the movable shaft 3 rotates, the spherical bumps 33 are alternately engaged with the filter holes of the filter cylinder 21. When the movable shaft 3 rotates, it drives the cleaning roller 32 to rotate through the connecting plate 31. The spherical bumps 33 on the cleaning roller 32 are clamped in the filter holes of the filter cylinder 21. Therefore, while rotating in a circular motion around the movable shaft 3, it also rotates self - sufficiently, so that the spherical bumps 33 at its upper end are alternately engaged with the filter holes of the filter cylinder 21, thereby ejecting and cleaning the impurities stuck in the filter holes.

[0027] In one embodiment, the upper end of the movable shaft 3 passes through and extends out from the upper wall of the filter cylinder 21. The driving component is a spiral fan blade 4 arranged at the upper end of the movable shaft 3. A connecting cylinder 41 sleeved outside the spiral fan blade 4 is arranged on the filter cylinder 21. A water - passing hole 42 communicating with the connecting cylinder 41 is opened on the filter cylinder 21; a sealing plate 43 is arranged at the upper end of the bell - mouth 2. One end of the connecting cylinder 41 away from the filter cylinder 21 passes through the sealing plate 43 and is connected to the water suction pipe 11. When the pump body 1 performs pumping and suction, water flows into the inside of the connecting cylinder 41 through the filter cylinder 21 and flows towards the water suction pipe 11. When the water flows through the connecting cylinder 41, the spiral fan blade 4 inside it is driven to rotate under the action of the water flow, and then drives the movable shaft 3 to rotate synchronously. Thus, the clogging prevention and unclogging mechanism can be driven to work by the pump suction force, without adding additional driving equipment and control systems.

[0028] In one embodiment, the lower end of the movable shaft 3 passes through and extends out from the lower wall of the filter cylinder 21 and is fixedly connected with a centrifugal cylinder 5. The inner diameter of the centrifugal cylinder 5 is larger than the outer diameter of the filter cylinder 21. Through the arrangement of the centrifugal cylinder 5, the impurities filtered by the filter cylinder 21 and cleaned by the clogging prevention and unclogging mechanism will precipitate and fall into the inside of the centrifugal cylinder 5 for collection. A slag - dropping port 51 is opened at the outer edge part of the bottom of the centrifugal cylinder 5. A collecting component detachably connected to the bell - mouth 2 and located below the centrifugal cylinder 5 is provided. The collecting component includes a collecting cylinder 61 with water - permeable holes 6 opened on its side wall. A circular hole 62 larger than the outer diameter of the centrifugal cylinder 5 is opened at the upper end of the collecting cylinder 61. After the centrifugal cylinder 5 collects impurities, it is connected to the movable shaft 3 and is thus driven by the movable shaft 3 to rotate. The impurities inside it are then thrown to the side wall part under the action of centrifugal force, and then accumulate in large quantities to generate a large gravity, thereby accelerating the fall into the inside of the water - permeable holes 6 through the slag - dropping port 51 for collection, improving the collection rate of impurities, and preventing them from continuing to disperse in the water body after filtration to cause pollution. By providing the water - permeable holes 6 on the side wall of the collecting cylinder 61, the water can be filtered out after it is taken out of the pool.

[0029] In one embodiment, connecting arms 7 are provided on both sides of the collection cylinder 61, a through-connection groove 71 for the connecting arms 7 to pass through is provided on the bell mouth 2, a bolt 72 is threadedly connected to the connecting arm 7, and a thread groove 73 adapted to the bolt 72 is provided on the side wall of the through-connection groove 71. The collection cylinder 61 is fixed to the bell mouth 2 by passing the connecting arm 7 through the through-connection groove 71 and then using the bolt 72 to ensure its stability. When a certain amount of impurities are collected inside the collection cylinder 61, it can be removed from the bell mouth 2 to clean the impurities uniformly.

[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
