Description

Technical Field

[0001] The utility model relates to the technical field of double-suction pumps, in particular to a water outlet filtering device of a double-suction pump. Background Art

[0002] As an important form of centrifugal pump, double suction pump is widely used in engineering because of its high head and large flow rate. The impeller of this pump type is actually composed of two back-to-back impellers, and the water flowing out of the impellers flows into a volute. The double suction pump has the following characteristics: it is equivalent to two single suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same impeller outer diameter.

[0003] Existing double-suction pumps may contain mud and sand in the water during operation, but most of them do not have a filtering structure. Therefore, when the mud and sand accumulate to a certain extent, it will affect the normal operation of the double-suction pump and increase the subsequent maintenance costs, so it is necessary to install a filtering structure.

[0004] Therefore, there is room for improvement, and the utility model provides a water outlet filtering device for a double-suction pump. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a water outlet filtering device for a double-suction pump, and the specific scheme is as follows:

[0006] A water outlet filtering device for a double-suction pump comprises a pump body, a filtering mechanism is arranged outside the pump body, and the filtering mechanism extends into the interior of the pump body;

[0007] The filtering mechanism includes two limiting rings, which are fixedly embedded in both sides of the pump body, and are symmetrically arranged with the center line of the pump body as the axis. Two card slots are provided inside the two limiting rings, and the four card slots are symmetrically arranged in pairs with the center line of the two limiting rings as the axis. Filters are provided on the outside of the two limiting rings, and two blocks are fixedly embedded inside the two filter screens. The inner ends of the four blocks extend into the four slots respectively, and the four blocks match the four slots respectively. The two filter screens are respectively fitted with the two limiting rings, and threaded grooves are provided inside the two sides of the pump body, and water pipes are threadedly inserted into the two threaded grooves, and auxiliary components are provided on the outside of the two limiting rings.

[0008] Therefore, when in use, the two filter screens can filter the silt. When the two filter screens need to be disassembled later, the two filter screens can be taken out from the inside of the pump body through auxiliary components. After the silt and debris inside the two filter screens are cleaned up, the two filter screens can be installed to the inside of the two sides of the pump body in turn with the help of external tools. Since the four blocks are matched with the four card slots respectively, the two filter screens can be positioned to make their installation more stable. Through the above structure, the problem that due to the lack of filtering structure, when the silt accumulates to a certain extent, it will affect the normal operation of the double-suction pump and increase the later maintenance cost is solved.

[0009] Furthermore, the auxiliary component includes two sealing rings, and the two sealing rings are fixedly sleeved on the outsides of the two water pipes respectively.

[0010] Therefore, by providing two sealing rings, the sealing between the water pipe and the pump body can be strengthened, thereby achieving a better use effect.

[0011] Furthermore, the inner sides of the two sealing rings are respectively tightly fitted with the outer walls on both sides of the pump body, and the two water pipes are respectively located on the outsides of the two filters.

[0012] Furthermore, two supporting legs are fixedly connected to the bottom of the pump body, and a base is fixedly connected to the bottom of the two supporting legs.

[0013] Therefore, by providing two supporting legs and a base, the pump body can be supported.

[0014] Furthermore, two arc-shaped grooves are respectively arranged on the outer sides of the two filter screens, and the four arc-shaped grooves are respectively arranged symmetrically with the center lines of the two filter screens as axes.

[0015] Furthermore, protrusions are embedded in the four arc-shaped grooves, and the four arc-shaped grooves are matched with four protrusions respectively.

[0016] Therefore, the four arc-shaped grooves and the four protrusions cooperate with each other, so that the pull rod can be easily rotated later, thereby improving the use effect.

[0017] Furthermore, two pull rods are fixedly connected to the outer sides of the four protrusions, and the two pull rods are respectively located between the two filter screens and the two water pipes.

[0018] Therefore, by providing two pull rods, it is convenient for the staff to take the two filters at a later time, thereby achieving the purpose of increasing the installation and disassembly speed.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] The utility model solves the problem that the normal operation of the double-suction pump will be affected and the later maintenance cost will be increased when the sediment accumulates to a certain extent due to the lack of filtering structure by arranging the filtering mechanism.

[0030] Specifically, the filtering mechanism includes two limiting rings 2, which are fixedly embedded in the inside of the two sides of the pump body 1 respectively. The two limiting rings 2 are symmetrically arranged with the center line of the pump body 1 as the axis. Two card grooves 11 are provided inside the two limiting rings 2. The four card grooves 11 are symmetrically arranged in pairs with the center lines of the two limiting rings 2 as the axis. Filter screens 3 are provided on the outside of the two limiting rings 2. Two card blocks 4 are fixedly embedded inside the two filter screens 3. The inner ends of the four card blocks 4 extend to the inside of the four card grooves 11 respectively. The four card blocks 4 are matched with the four card grooves 11 respectively. The two filter screens 3 are respectively fitted with the two limiting rings 2. Threaded grooves 12 are provided inside the two sides of the pump body 1, and water pipes 5 are threadedly inserted into the two threaded grooves 12.

[0031] See also Figure 1 , auxiliary components are provided on the outside of the two limit rings 2, and the auxiliary components include two sealing rings 6, which are fixedly sleeved on the outside of the two water pipes 5, and the inner sides of the two sealing rings 6 are tightly fitted with the outer walls of the two sides of the pump body 1, respectively. The two water pipes 5 are located on the outside of the two filters 3, respectively. By providing two sealing rings 6, the sealing between the water pipes 5 and the pump body 1 can be strengthened, so that the use effect can be better;

[0032] See also Figure 1 and Figure 3 Two supporting legs 7 are fixedly connected to the bottom of the pump body 1, and a base 8 is fixedly connected to the bottom of the two supporting legs 7. Two arc-shaped grooves are provided on the outer sides of the two filters 3, and the four arc-shaped grooves are symmetrically arranged with the center lines of the two filters 3 as axes.

At the same time, by setting up two pull rods 10, it is convenient for the staff to take the two filter screens 3 later, thereby improving the installation and disassembly speed.

[0034] The implementation process of this embodiment is as follows:

[0035] When in use, the two filter screens 3 can filter the silt. When the two filter screens 3 need to be disassembled later, the two water pipes 5 can be rotated and separated from the pump body 1 first, and then with the help of external tools, the two pull rods 10 are clamped in turn and pulled to respectively take out the two filter screens 3 from the inside of the pump body 1. Since the four protrusions 9 are matched with the four arc-shaped grooves respectively, the angles of the two pull rods 10 can be flexibly adjusted, making the scope of application wider. After the silt and debris inside the two filter screens 3 are cleaned up, the two filter screens 3 are installed to the inside of the two sides of the pump body 1 with the help of external tools again. Since the four clamping blocks 4 are matched with the four clamping grooves 11 respectively, and the inner ends of the two water pipes 5 are respectively fitted with the outer sides of the two pull rods 10, the two filter screens 3 can be positioned to make them more firmly installed. Through the above structure, the problem that the normal operation of the double-suction pump will be affected when the silt accumulates to a certain extent due to the lack of a filtering structure is solved, thereby increasing the problem of later maintenance costs.
