Description

Technical Field

[0001] This utility model relates to the field of high-pressure cooling water pump technology, and in particular to a filter screen device for a high-pressure cooling water pump. Background Technology

[0002] The forced chiller water pump in the synthesis system has a fixed filter screen welded to its inlet pipe. This filter screen prevents foreign objects from entering the pump's inlet pipe during water intake, thus preventing blockages or affecting the heat exchange efficiency of the forced chiller. Especially in summer when mosquitoes are abundant, they easily fall into the water tank. After prolonged use in the tank, impurities or insects can settle at the pump's inlet and adhere to the filter screen. This blockage reduces the pump's liquid intake, affecting the heat exchange efficiency of the forced chiller and resulting in poor ammonia recovery. Therefore, it is necessary to replace the filter screen at the forced chiller water pump's inlet regularly.

[0003] However, the filter screen of the existing forced chiller water pump is welded and fixed to the inlet pipe, which is inconvenient to disassemble and replace. The only option is to clean the filter screen. When it is necessary to clean the filter screen at the inlet of the forced chiller water pump, the forced chiller water pump must be stopped and the water in the pool must be drained before the filter screen can be cleaned. The cleaning efficiency of the filter screen is low. Moreover, after the forced chiller water pump stops running, the pressure of the normal synthesis system is high, and production needs to be reduced to handle the problem, which seriously affects normal production. Utility Model Content

[0004] To address the technical problem in existing technologies where it is inconvenient to disassemble and replace the filter screen, and where the water pump of the chiller must be stopped before cleaning the filter screen at the inlet of the chiller pump, this utility model provides the following technical solution.

[0005] This utility model discloses a filter screen device for a powerful cooling water pump, including a connecting pipe connected to an inlet pipe. The connecting pipe is fixedly connected to a receiving body having a water passage hole and a receiving groove. The receiving body is movably connected to a detachable filter screen. The detachable filter screen includes a plate body matching the receiving groove and a filter screen corresponding to the axial direction of the water passage hole. The receiving body is connected horizontally and longitudinally by horizontal bolts and longitudinal bolts connected to the plate body, respectively.

[0006] As a further technical solution, the container is provided with a first connecting hole and a second connecting hole in the horizontal direction and in the vertical direction, respectively. The plate is provided with a horizontal screw hole corresponding to the first connecting hole and connected to the horizontal bolt, and a vertical screw hole corresponding to the second connecting hole and connected to the vertical bolt.

[0007] As a further technical solution, the accommodating body includes a shell fixedly connected to the connecting pipe, and guide grooves are provided on both sides of the accommodating through groove, and the plate is provided with guide edges that match the guide grooves.

[0008] As a further technical solution, a retaining ring is provided on the side of the connecting pipe away from the water inlet pipe, and a sealing gasket is placed on the retaining ring to press against the water inlet pipe.

[0009] As a further technical solution, the connecting pipe is threadedly connected to the water inlet pipe, and the outer wall of the connecting pipe is provided with a plurality of first threaded holes, the first threaded holes being connected to limiting bolts that abut against the water inlet pipe.

[0010] As a further technical solution, the connecting pipe is welded and fixed to the water inlet pipe.

[0011] The beneficial effects of this utility model are as follows: A connecting pipe is installed in the inlet pipe of the forced cooling water pump. This connecting pipe is fixedly connected to a receiving body, which is connected to a removable filter screen via horizontal and vertical bolts. The removable filter screen can be replaced simply by removing two bolts. Furthermore, the horizontal and vertical bolts secure the removable filter screen in two different directions, ensuring its stable use in the water tank. This allows the forced cooling water pump to continue operating without shutting down the forced cooling unit, guaranteeing normal production of the synthesis system. Moreover, when replacing the removable filter screen, the new screen enters the receiving channel while the old screen leaves, ensuring seamless replacement and guaranteeing the cleanliness of the water entering the inlet pipe, thus ensuring the safe operation of the forced cooling water pump.

[0015] like Figure 1 and Figure 2 As shown, in a preferred embodiment, the present invention provides a powerful cooling water pump filter screen device, including a connecting pipe 1 connected to a water inlet pipe 8. Both the connecting pipe 1 and the water inlet pipe 8 are metal pipe structures. The water inlet pipe 8 is connected to a powerful cooling water pump for drawing water from a water tank.

[0016] There are several ways to connect the connecting pipe 1 to the water inlet pipe 8. One method is to weld the connecting pipe 1 to the water inlet pipe 8 to ensure a stable connection. Alternatively, the connecting pipe 1 can be threaded to the water inlet pipe 8. In this case, the outer wall of the water inlet pipe 8 has external threads, and the inner wall of the connecting pipe 1 has internal threads, facilitating the threaded connection and fixation. Several first threaded holes 102 are provided through the outer wall of the connecting pipe 1. Each first threaded hole 102 is connected to a limiting bolt 2 that abuts against the water inlet pipe 8. After threading the connecting pipe 1 to the water inlet pipe 8, the limiting bolt 2 is passed through the first threaded holes 102 and tightened to prevent shaking at the connection point during water flow, ensuring a stable connection.

[0017] Meanwhile, a clamping ring 101 is provided on the side of the connecting pipe 1 away from the water inlet pipe 8. A sealing gasket 7 is placed on the clamping ring 101 to clamp against the water inlet pipe 8. Thus, after the connecting pipe 1 is connected and fixed to the water inlet pipe 8, water leakage from the water inlet pipe 8 can be prevented.

[0018] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the connecting pipe 1 is fixedly connected to a receiving body 3, which is made of stainless steel. The receiving body 3 includes a housing 301 fixedly connected to the connecting pipe 1. The housing 301 has a water passage hole 304 communicating with the connecting pipe 1. Water in the pool flows from the water passage hole 304 to the connecting pipe 1 and the water inlet pipe 8. At this time, the housing 301 has a receiving groove 302 in the horizontal direction. A detachable filter screen 4 is movably connected to the receiving groove 302. The detachable filter screen 4 includes a plate 401 that matches the receiving groove 302 and a filter screen 402 that corresponds axially to the water passage hole 304. The plate 401 can slide in the receiving groove 302 and is fixedly connected to the housing 301 by bolts. Therefore, the removable filter screen 4 can be inserted into the receiving groove 302 from one side and fixed with bolts. It can be used normally. When the filter screen 402 needs to be replaced, the bolts can be removed and the removable filter screen 4 can be removed from one side of the receiving groove 302.

[0019] In a preferred embodiment, the housing 3 is connected horizontally by a horizontal bolt 5 and vertically by a longitudinal bolt 6, which are connected to the plate 401. The horizontal bolt 5 and the longitudinal bolt 6 can be connected to the housing 301 and the plate 401 in two different directions with different preloads, which can ensure the stable use of the detachable filter screen 4 in the water tank and prevent it from slipping off. At this time, the housing 3 is provided with a first connecting hole 305 and a second connecting hole 306 in the horizontal and vertical directions, respectively. The plate 401 is provided with a horizontal screw hole 403 corresponding to the first connecting hole 305 and a longitudinal screw hole 404 corresponding to the second connecting hole 306. The horizontal bolt 5 passes through the first connecting hole 305 and is threaded to the horizontal screw hole 403, and the longitudinal bolt 6 passes through the second connecting hole 306 and is threaded to the longitudinal screw hole 404, thus completing the connection and fixation of the housing 301 and the plate 401.

[0020] In a preferred embodiment, guide grooves 303 are provided on both sides of the inner wall of the receiving groove 302, and the plate 401 is provided with guide edges 405 that match the guide grooves 303. When it is necessary to replace the removable filter screen 4, only the horizontal bolts 5 and the longitudinal bolts 6 need to be removed, so that the removable filter screen 4 can slide out of the receiving groove 302. Moreover, the entry of the new removable filter screen 4 into the receiving groove 302 and the removal of the old removable filter screen 4 from the receiving groove 302 can be carried out simultaneously, ensuring seamless replacement of the removable filter screen 4, ensuring that the water entering the inlet pipe 8 is clean, and ensuring the safe operation of the forced cooling water pump.
