Description

Technical Field

[0001] This utility model relates to the field of submersible pump motor technology, and in particular to a device for preventing water from entering the vertical submersible pump motor in a spray tower tank. Background Technology

[0002] In many industrial sectors, such as chemical and environmental protection, spray towers are widely used in processes such as waste gas treatment and gas purification. The vertical submersible pump inside the spray tower tank plays a crucial role in transporting the spray liquid and maintaining the circulation of the spray system, and its motor is the core power source for the normal operation of the entire submersible pump.

[0003] However, due to the special working environment of submersible pumps, the motor is usually in a state of being close to or even partially submerged in the liquid. In actual operation, there is a risk that liquid can easily enter the motor through various gaps and channels. Once water enters the motor, it will cause a series of problems such as short circuits, insulation damage, and corrosion of components, seriously affecting the normal service life of the motor, increasing the equipment failure rate, and even causing the entire spray tower system to malfunction, resulting in adverse consequences such as production interruption and increased maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a device to prevent water from entering the motor of a vertical submersible pump in a spray tower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for preventing water ingress into the motor of a vertical submersible pump in a spray tower, comprising a tower body and a water collection tank, wherein the water collection tank and the tower body are fixedly connected, and an opening is provided on the surface of the water collection tank, the opening communicating with the tower body. A partition is provided on the inner side of the opening, and the left, right and top sides of the partition are evenly and fully welded with the opening. An mounting plate is fixedly connected to the surface of the water collection tank, and a motor body is fixedly connected to the surface of the mounting plate. A pump body is fixedly connected to the lower surface of the mounting plate, and the motor body is coaxially connected to the motor body. A water outlet pipe is fixedly connected to the surface of the pump body, and a connecting pipe is fixedly connected to the top end of the water outlet pipe. A spray pipe is fixedly connected to the other end of the connecting pipe, and the spray pipe is located inside the tower body. An air inlet pipe and an exhaust pipe are fixedly connected to the surface of the tower body. An installation shell is provided on the surface of the water inlet end of the pump body, and a filter screen is provided inside the installation shell.

[0006] Preferably, the pump body is made of PP plastic material that is resistant to acid and alkali corrosion.

[0007] Preferably, the surface of the water collection tank is provided with a threaded hole, the surface of the mounting plate is provided with a circular hole, a bolt is inserted into the circular hole, and the bolt is threaded into the inside of the threaded hole.

[0008] Preferably, the surface of the water collection tank is provided with a square groove, the bottom of the square groove is provided with a slot, and a sealing gasket is provided between the square groove and the mounting plate.

[0009] Preferably, a water inlet pipe is fixedly connected to the surface of the tower body, and a valve is fixedly connected to the surface of the water inlet pipe.

[0010] Preferably, a drain pipe is fixedly connected to the bottom of the water collection tank, and a valve is fixedly connected to the surface of the drain pipe.

[0011] Preferably, a locking assembly is fixedly connected to the surface of the mounting shell. The locking assembly includes a block, and a pin is slidably connected inside the block. A pull rod is fixedly connected to the surface of the pin, and a handle is fixedly connected to the other end of the pull rod. A spring is sleeved on the surface of the pull rod, and a slot is opened on the surface of the pump body. The pin is inserted into the inside of the slot.

[0014] Preferably, a limiting rod is fixedly connected to the inner wall of the mounting shell, and a limiting groove is formed on the surface of the pump body, with the limiting rod slidably connected inside the limiting groove.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, by adding a welded partition inside the opening, a certain gap is left between the bottom of the partition and the bottom of the water tank. The gap height is less than the normal water tank liquid level. Ultimately, a water seal is formed between the partition and the bottom liquid level of the water tank, dividing the tower body and the water tank into two relatively sealed spaces. Finally, the positive pressure inside the tower body is sealed on one side of the partition, so that the motor body side is at normal pressure. Water vapor can no longer enter the motor body due to positive pressure, thus solving the problem of motor burnout caused by water vapor entering the motor body. By using PP plastic material for the pump body, the overall acid and alkali corrosion resistance of the pump body is greatly improved.

[0017] 2. In this utility model, the spring force inside the block makes the pin firmly inserted into the slot, thus fixing the mounting shell and making the installation of the filter screen simpler and faster. At the same time, by pulling the handle, the handle drives the pull rod and the pin to slide inside the block, thus releasing the fixing of the mounting shell and facilitating the replacement of the filter screen later.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1: As Figure 1 - Figure 4As shown, this utility model provides a technical solution: a device for preventing water from entering the motor of a vertical submersible pump in a spray tower, comprising a tower body 1 and a water collection tank 2, the water collection tank 2 and the tower body 1 being fixedly connected, the surface of the water collection tank 2 having an opening 3, the opening 3 communicating with the tower body 1, a partition 4 being provided on the inner side of the opening 3, the left, right and top sides of the partition 4 being evenly and fully welded to the opening 3, an mounting plate 10 being fixedly connected to the surface of the water collection tank 2, a motor body 11 being fixedly connected to the surface of the mounting plate 10, a pump body 12 being fixedly connected to the lower surface of the mounting plate 10, the pump body 12 being coaxially connected to the motor body 11, a water outlet pipe 13 being fixedly connected to the surface of the pump body 12, a connecting pipe 14 being fixedly connected to the top end of the water outlet pipe 13, and a spray pipe 15 being fixedly connected to the other end of the connecting pipe 14, the spray pipe 15 being located inside the tower body 1, the tower body 1 being fixedly connected to the motor body 1. The surface of the pump body 1 is fixedly connected to an air inlet pipe 9 and an exhaust pipe 7. The surface of the water inlet end of the pump body 12 is provided with a mounting shell 17, and a filter screen 21 is provided inside the mounting shell 17. The pump body 12 is made of PP plastic material that is resistant to acid and alkali corrosion. The surface of the water collection tank 2 is provided with a threaded hole 20. The surface of the mounting plate 10 is provided with a round hole 19. A bolt 18 is inserted into the round hole 19 and the bolt 18 is threaded into the threaded hole 20. The surface of the water collection tank 2 is provided with a square groove 5. The bottom of the square groove 5 is provided with a slot 6. A sealing gasket 16 is provided between the square groove 5 and the mounting plate 10. The surface of the tower body 1 is fixedly connected to a water inlet pipe 8. The surface of the water inlet pipe 8 is fixedly connected to a valve 33. The bottom of the water collection tank 2 is fixedly connected to a drain pipe 32. The surface of the drain pipe 32 is fixedly connected to a valve 34.

[0029] In this embodiment, by adding a welded partition 4 inside the opening 3, with a certain gap between the bottom of the partition 4 and the bottom of the water tank, the gap height being less than the normal water tank liquid level, a water seal is formed between the partition 4 and the bottom liquid level of the water tank 2, dividing the tower body 1 and the water tank 2 into two opposing sealed spaces. This ultimately seals the tower body 1 with positive pressure on one side of the partition 4, keeping the motor body 11 at normal pressure. Water vapor can no longer enter the motor body 11 due to positive pressure, thus solving the problem of motor burnout caused by water vapor entering the motor body 11. By using PP plastic material for the pump body 12, the pump... The overall acid and alkali corrosion resistance of the body 12 is greatly improved. It is connected to the inside of the threaded hole 20 by bolts 18, which facilitates the disassembly of the motor body 11 and the main body. The sealing gasket 16 between the square groove 5 and the mounting plate 10 can improve the sealing between the mounting plate 10 and the water collection tank 2, ensuring the normal pressure state in the water collection tank 2 and preventing a large amount of water from the bottom of the tower body 1 from flowing into the water collection tank 2. Water can be easily added to the inside of the tower body 1 through the water inlet pipe 8 and the control valve 1 33. At the same time, the control valve 2 34 can also facilitate the discharge of water that has been used for a long time from the tower body 1, and also facilitate the discharge of impurities in the tower body 1.

[0030] Example 2: As Figure 3 - Figure 4 As shown, a locking assembly is fixedly connected to the surface of the mounting shell 17. The locking assembly includes a block 24, and a pin 25 is slidably connected inside the block 24. A pull rod 26 is fixedly connected to the surface of the pin 25, and a handle 27 is fixedly connected to the other end of the pull rod 26. A spring 28 is sleeved on the surface of the pull rod 26. A slot 31 is opened on the surface of the pump body 12, and the pin 25 is inserted into the slot 31. There are two sets of pins 25, which are symmetrically distributed on both sides of the middle of the surface of the mounting shell 17. A support plate 29 is fixedly connected to the surface of the block 24. A slot 30 is opened on the surface of the support plate 29. A limit rod 22 is fixedly connected to the inner wall of the mounting shell 17. A limit groove 23 is opened on the surface of the pump body 12, and the limit rod 22 is slidably connected inside the limit groove 23.

[0031] In this embodiment, the spring 28 inside the block 24 causes the pin 25 to be securely inserted into the slot 31, thus fixing the mounting shell 17 and making the installation of the filter screen 21 simpler and faster. At the same time, by pulling the handle 27, the handle 27 drives the pull rod 26 and the pin 25 to slide inside the block 24, thereby releasing the fixing of the mounting shell 17 and facilitating the replacement of the filter screen 21 later. By locking the limiting rod 22 inside the mounting shell 17 into the limiting groove 23 on the surface of the pump body 12, the slot 31 on the surface of the body can be quickly aligned with the pin 25, making it easier for the pin 25 to be inserted into the slot 31. Before installing the mounting shell 17, by placing the handle 27 inside the slot 30 on the support plate 29, the ease of installation of the mounting shell 17 can be further improved.

[0032] The working principle of this embodiment is as follows: In use, firstly, the sealing gasket 16 is placed inside the square groove 5. Then, the pump body 12 is inserted into the water collection tank 2 through the slot 6 inside the square groove 5. Next, the bolt 18 is inserted into the round hole 19 on the mounting plate 10 and screwed into the threaded hole 20 on the water collection tank 2. This achieves the purpose of fixing the motor body 11 and the pump body 12 to the water collection tank 2, and also facilitates the removal of the pump body 12 and the motor body 11 from the water collection tank 2. Simultaneously, the sealing gasket 16 improves the sealing between the mounting plate 10 and the water collection tank 2, ensuring a constant pressure inside the water collection tank 2 and preventing a large amount of water from the bottom of the tower body 1 from flowing into the water collection tank 2. Then, by controlling the valve 33 on the water supply pipe, the valve 33 is opened, allowing water to pass through… The water inlet pipe 8 is introduced into the interior of the tower body 1. A baffle 4 is welded inside the opening 3, with a certain gap between the bottom of the baffle 4 and the bottom of the water tank. The gap height is less than the normal water tank liquid level. Ultimately, a water seal is formed between the baffle 4 and the bottom liquid level of the water tank 2, dividing the tower body 1 and the water tank 2 into two opposing sealed spaces. This ultimately seals the tower body 1 with positive pressure on one side of the tower body 1 with baffle 4, keeping the motor body 11 at normal pressure. Water vapor can no longer enter the motor body 11 due to positive pressure, thus solving the problem of motor burnout caused by water vapor entering the motor body 11. By using PP plastic material for the pump body 12, the overall acid and alkali corrosion resistance of the pump body 12 is greatly improved. Subsequently, the gas to be purified is introduced into the interior of the tower body 1 through the air inlet pipe 9. When the motor body 11 is started, the output end of the motor body 11 drives the pump body 12 to work. The pump body 12 generates suction, causing the water in the tower body 1 to be filtered through the filter screen 21 in the mounting shell 17 and then enter the interior of the outlet pipe 13 through the pump body 12. Finally, it is sprayed from the nozzle on the spray pipe 15 through the connecting pipe 14 to achieve the purpose of purifying the gas. The purified gas is discharged through the exhaust pipe 7. When it is necessary to replace the water in the tower body 1, the wastewater in the tower body 1 can be easily discharged by opening the valve 34 on the drain pipe 32 so that new water can be injected into the tower body 1 again. When the mounting shell 17 is installed on the water inlet end of the pump body 12, the spring 28 in the block 24 makes the pin 25 firmly inserted into the slot 31. The internal mechanism secures the mounting housing 17, making the installation of the filter disc 21 simpler and faster. Simultaneously, by pulling the handle 27, the handle 27 causes the pull rod 26 and the pin 25 to slide within the block 24, releasing the mounting housing 17 and facilitating future replacement of the filter disc 21. After the mounting housing 17 is installed on the pump body 12, the limiting rod 22 inside the mounting housing 17 engages with the limiting groove 23 on the surface of the pump body 12, allowing the slot 31 on the surface of the body to quickly align with the pin 25, thus facilitating the insertion of the pin 25 into the slot 31. Before installing the mounting housing 17, placing the handle 27 inside the slot 30 on the support plate 29 further enhances the ease of installation.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
