Description

Technical Field

[0001] The invention belongs to the technical field of sealing shells for submersible pumps, and in particular relates to a sealing shell for submersible pumps. Background Art

[0002] Submersible pumps are mainly used for farmland irrigation and water supply for humans and livestock in mountainous areas. They can also be used for central air-conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines, and construction site drainage. The sealed casing for submersible pumps is an important component of the submersible pump. The sealed casing wraps the entire water pump to form a closed space to prevent damage to the pump body.

[0003] The existing sealed housings for submersible pumps have the following problems:

[0004] Submersible pumps generate heat when working. The existing sealed housings for submersible pumps cannot effectively dissipate the heat generated by the submersible pumps during operation. The components used for heat dissipation are prone to oxidation when in contact with water, thereby reducing the heat dissipation effect of the heat dissipation components. In addition, the traditional sealed housings for submersible pumps cannot monitor the flow rate of cooling water, which causes the heat generated by the submersible pumps during operation to not be dissipated in time, reducing the operating performance of the submersible pumps. Therefore, the existing use requirements for submersible pump sealed housings cannot be met. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present solution provides a sealed housing for a submersible pump that can effectively dissipate the heat generated by the submersible pump during operation while avoiding oxidation of the surface of the heat dissipation components, and can monitor the flow rate of cooling water to ensure that the heat generated by the submersible pump during operation can be dissipated in time.

The water absorption box is opened at the lower end, and the water absorption filter is arranged on the inner wall of the water absorption box opening; the water delivery mechanism includes a water delivery cylinder, a water delivery valve, a water delivery pipe and a drain valve. The water delivery cylinder is arranged on the bottom inner wall of the sealed shell, the water delivery valve is connected to the upper wall of the water delivery cylinder, the water delivery pipe passes through the sealed shell and is connected between the water absorption box and the water delivery cylinder, and the drain valve passes through the upper wall of the sealed shell.

[0008] When in use, the submersible pump is placed inside the sealed shell, the suction end of the submersible pump is connected to the water supply valve, the discharge end of the submersible pump is connected to the drain valve, the end of the drain valve away from the submersible pump is connected to the external drainage pipe, the sealed shell drives the submersible pump to sink into the water, the submersible pump is started, the water flows through the water suction filter and enters the water suction box, the water inside the water suction box flows into the water supply cylinder through the water supply pipe, and the water inside the water supply cylinder passes through the water supply valve and is discharged into the external drainage pipe through the drain valve under the suction force of the submersible pump.

[0009] Preferably, the water filtering mechanism includes a water filter box, an oxygen-removing filter, a water-permeable bag and a sponge iron material. A plurality of groups of the water filter boxes are arranged on the top side wall of the sealed shell. The water filter box is arranged with an upper opening. The oxygen-removing filter is arranged on the inner wall of the water filter box opening. The water-permeable bag is arranged inside the water filter box. The sponge iron material is arranged inside the water-permeable bag. The cooling mechanism includes a cooling box, a cooling pipe, a radiation copper plate, a heat-conducting copper column and a cooling copper plate. The cooling box is arranged on the side wall of the sealed shell between the water filter box and the water suction box. The cooling pipe is connected between the cooling box and the water filter box. The cooling copper plate is arranged through the side of the sealed shell close to the cooling box. The heat-conducting copper column is arranged on the cooling copper plate. On the side away from the cooling box, the radiation copper plate is arranged on the side of the heat-conducting copper column away from the cooling copper plate; the water exposure mechanism includes a water pump, a pipe clamp, a water pumping pipe, a buoyancy tube, a buoyancy airbag, a spray ball and a spray port, the water pump is arranged on the bottom wall of the cooling box, the water pump suction pipe is penetrated and arranged inside the cooling box, the pipe clamp is arranged on the side of the filter box away from the sealing shell, the water pumping pipe penetrates the pipe clamp and is arranged at the drainage end of the water pump, the buoyancy tube is slidably arranged inside the water pumping pipe, the buoyancy airbag is arranged at one end of the buoyancy tube away from the water pumping pipe, the spray ball is connected and arranged on the side of the water pumping pipe close to the buoyancy airbag, and multiple groups of spray ports are arranged on the side wall of the spray ball.

[0010] When in use, a submersible pump will generate more heat when the speed is too high. In order to ensure that the submersible pump can maintain stable performance during long-term operation, it is necessary to dissipate the heat generated by the submersible pump. The water pump draws water around the sealed shell through the pumping end, and the water enters the water filter box after being filtered by the oxygen removal filter. Since the permeable bag is a permeable cloth bag, the water entering the water filter box passes through the permeable bag and contacts the sponge iron material. The reducibility of the sponge iron material is used to react with the dissolved oxygen in the water to remove the dissolved oxygen in the water entering the water filter box, thereby reducing the temperature. The surface of the copper plate gradually emits The probability of forming a layer of oxide by oxidation reaction is reduced to ensure the heat exchange efficiency between the cooling copper plate and water. The submersible pump is placed between the radiation copper plates. The radiation copper plates guide the heat generated by the submersible pump into the cooling copper plates through the heat-conducting copper columns. The water in the filter tank that eliminates dissolved oxygen flows into the cooling box through the cooling pipe. The water entering the cooling box exchanges heat with the cooling copper plate. The water flowing through the cooling box cools the cooling copper plate. The cooling copper plate cools the radiation copper plate through the heat-conducting copper column. After the temperature of the radiation copper plate is reduced, the submersible pump is cooled, thereby ensuring the efficient operation of the submersible pump. The cooled water enters the water lifting pipe. After the sealed shell sinks into the water, the buoyancy airbag drives the buoyancy tube to slide and rise along the inside of the water lifting pipe under the action of its buoyancy. The buoyancy airbag floats on the water surface. The spray ball is located above the buoyancy airbag. When the sponge iron material is immersed in water containing dissolved oxygen, the sponge iron material undergoes an oxidation-reduction reaction with the oxygen dissolved in the water. During this reaction, the iron atoms lose electrons and are oxidized into divalent iron ions. The divalent iron ions can pollute the water body. The water containing divalent iron ions enters the buoyancy tube through the water lifting pipe ... The water containing divalent iron ions inside the tube flows into the spray ball, and the water inside the spray ball is sprayed onto the water surface through the spray port. On the one hand, the contact area between the water containing divalent iron ions and the air is increased, so that the divalent iron ions react with the oxygen in the air. The divalent iron ions will be oxidized into trivalent iron ions. After falling into the water, they will be further hydrolyzed into ferric hydroxide and precipitated at the bottom of the water. On the other hand, according to the head of the water sprayed from the spray port, the flow state of the cooling water can be monitored in real time to ensure the heat dissipation effect of the flowing water on the cooling copper plate and ensure the stable operation of the submersible pump.

[0011] Specifically, the pump locking mechanism includes a limit frame, a hanging port and a locking bolt. The limit frame is arranged on the inner wall of the sealing shell, the hanging port is arranged on the top side wall of the sealing shell, and multiple groups of locking bolts are arranged through the side wall of the sealing shell, and the locking bolts are threadedly connected to the sealing shell.

[0012] When in use, place the submersible pump inside the limit frame, rotate the locking bolt, and the locking bolt rotates along the inner wall of the sealing shell close to the side wall of the submersible pump. The submersible pump is fixed inside the sealing shell, fixedly connected to the hanging port by a rope, and the sealing shell is sunk to the bottom of the water to facilitate water extraction operations.

[0013] The beneficial effects achieved by adopting the above structure are as follows:

[0014] Compared with the prior art, this solution adopts the method of shell heat dissipation and water pumping monitoring. Through the bottom suction pumping mechanism and water pumping cooling mechanism, under the action of the water absorption mechanism, water delivery mechanism, water filtering mechanism, cooling mechanism and water exposure mechanism, the heat generated during the operation of the submersible pump can be dissipated and cooled by the flowing water flow under the premise of ensuring that the cooling copper plate is not oxidized, thereby ensuring the stable operation of the submersible pump. Secondly, the cooling water is sprayed onto the water surface by the spraying ball barrel, so that it can be monitored in real time whether the flowing water cools the cooling copper plate, thereby To ensure that the submersible pump can perform pumping operations at a relatively low temperature, the water pump draws water around the sealed shell through the pumping end, and the water enters the water filter box after being filtered by the oxygen removal filter. Since the permeable bag is a permeable cloth bag, the water entering the water filter box passes through the permeable bag and contacts the sponge iron material. The reducibility of the sponge iron material reacts with the dissolved oxygen in the water to remove the dissolved oxygen in the water entering the water filter box, reducing the probability of gradual oxidation reaction on the surface of the cooling copper plate to form a layer of oxide, thereby ensuring the heat exchange efficiency between the cooling copper plate and water.

The cooling box 18 is arranged on the side wall of the sealed shell 1 between the water filter box 13 and the water suction box 4. The cooling pipe 19 is connected between the cooling box 18 and the water filter box 13. The cooling copper plate 22 is arranged through the sealed shell 1 on one side close to the cooling box 18.

The water pump 24 is arranged on the bottom wall of the cooling box 18, and the water suction pipe of the water pump 24 is penetrated and arranged inside the cooling box 18. The pipe clamp 25 is arranged on the side of the filter box 13 away from the sealing shell 1, and the water pipe 26 penetrates the pipe clamp 25 and is arranged at the drainage end of the water pump 24. The buoyancy tube 27 is slidably arranged inside the water pipe 26, and the buoyancy airbag 28 is arranged at one end of the buoyancy tube 27 away from the water pipe 26. The spray ball 29 is connected to the side of the water pipe 26 close to the buoyancy airbag 28, and multiple groups of spray ports 30 are arranged on the side wall of the spray ball 29.

[0033] The pump locking mechanism 31 includes a limit frame 32, a hanging port 33 and a locking bolt 34. The limit frame 32 is arranged on the inner wall of the sealing shell 1, the hanging port 33 is arranged on the top side wall of the sealing shell 1, and multiple groups of locking bolts 34 are penetrated through the side wall of the sealing shell 1. The locking bolts 34 are threadedly connected to the sealing shell 1.

[0034] When in use, place the submersible pump inside the limit frame 32, rotate the locking bolt 34, and the locking bolt 34 rotates along the inner wall of the sealing shell 1 close to the side wall of the submersible pump to fix the submersible pump inside the sealing shell 1. The submersible pump is placed inside the sealing shell 1, and the water pumping end of the submersible pump is connected to the water delivery valve 8, and the drainage end of the submersible pump is connected to the drainage valve 10. The end of the drainage valve 10 away from the submersible pump is connected to the external drainage pipe and is fixedly connected to the hanging port 33 through a rope. The sealing shell 1 drives the submersible pump to sink into the water, and the sealing shell 1 sinks to the bottom of the water. The submersible pump is started, and the water flows through the water suction filter 5 and then enters the water suction box 4. The water inside the water suction box 4 flows into the water delivery tube 7 through the water delivery pipe 9. The water inside the water delivery tube 7 passes through the water delivery valve 8 and the drainage valve 10 under the suction of the submersible pump to be discharged into the external drainage pipe, so as to facilitate the water extraction operation;

[0035] Specifically, when the speed of the submersible pump is too high, more heat will be generated. In order to ensure that the submersible pump can maintain stable performance during long-term operation, it is necessary to dissipate the heat generated by the submersible pump, control the water pump 24 to start, and the water pump 24 extracts water around the sealed shell 1 through the pumping end. The water enters the water filter box 13 after being filtered by the oxygen removal filter 14. Since the permeable bag 15 is a permeable cloth bag, the water entering the water filter box 13 passes through the permeable bag 15 and contacts the sponge iron material 16. The reducibility of the sponge iron material 16 is used to react with the dissolved oxygen in the water, and the dissolved oxygen in the water entering the water filter box 13 is removed, thereby reducing the probability of the surface of the cooling copper plate 22 gradually undergoing oxidation reaction to form a layer of oxide, thereby ensuring the heat exchange efficiency between the cooling copper plate 22 and the water.

[0036] The radiation copper plate 20 is located around the submersible pump. The radiation copper plate 20 introduces the heat generated by the submersible pump into the cooling copper plate 22 through the heat-conducting copper column 21. The water in the filter box 13 that eliminates dissolved oxygen flows into the cooling box 18 through the cooling pipe 19. The water entering the cooling box 18 exchanges heat with the cooling copper plate 22. The water flowing through the cooling box 18 cools the cooling copper plate 22. The cooling copper plate 22 cools the radiation copper plate 20 through the heat-conducting copper column 21. After the temperature of the radiation copper plate 20 is reduced, the submersible pump is cooled, thereby ensuring the efficient operation of the submersible pump. The cooled water enters the water lift pipe 26.

[0037] After the sealed shell 1 sinks into the water, the buoyancy airbag 28 drives the buoyancy tube 27 to slide and rise along the inside of the water lifting pipe 26 under the action of its buoyancy. The buoyancy airbag 28 floats on the water surface, and the spray ball 29 is located above the buoyancy airbag 28. When the sponge iron material 16 is immersed in the water containing dissolved oxygen, the sponge iron material 16 undergoes an oxidation-reduction reaction with the oxygen dissolved in the water. During this reaction, the iron atoms lose electrons and are oxidized into divalent iron ions. The divalent iron ions will cause pollution to the water body. The water containing divalent iron ions enters the inside of the buoyancy tube 27 through the water lifting pipe 26. The inside of the buoyancy tube 27 contains divalent iron. The ionized water flows into the spray ball 29, and the water inside the spray ball 29 is sprayed onto the water surface through the spray port 30. On the one hand, the contact area between the water containing divalent iron ions and the air is increased, so that the divalent iron ions react with the oxygen in the air. The divalent iron ions will be oxidized into trivalent iron ions. After falling into the water, they will be further hydrolyzed into ferric hydroxide and precipitated at the bottom of the water. On the other hand, according to the head of the water sprayed from the spray port 30, the flow state of the cooling water can be monitored in real time to ensure the heat dissipation effect of the flowing water on the cooling copper plate 22 and ensure the stable operation of the submersible pump. The above operation can be repeated when it is used next time.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0039] The above is a description of the present solution and its implementation methods, which is not restrictive. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creative design without departing from the creative purpose of the present solution, they should all fall within the protection scope of the present solution.
