Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, and particularly relates to a spray tower for preventing water leakage of a water tank. Background Technique

[0002] A spray tower, also known as a washing tower or a water scrubber, is an important industrial waste gas treatment device. It uses the full contact between waste gas and liquid to reduce the concentration of harmful substances in the waste gas through physical dissolution or chemical reaction, so as to meet the national emission standards. The spray tower is internally provided with a spray system, a packing layer and other structures. After the waste gas is treated by the spray liquid in the tower, the purification effect is remarkable. The spray tower is widely used in multiple industries such as chemical industry, pharmaceutical industry, painting, printing, etc. to treat the waste gas generated in the industrial production process, effectively reduce the environmental pollution caused by the waste gas, protect the ecological environment, improve the industrial production efficiency. At the same time, the structure of the spray tower is simple and easy to maintain and clean.

[0003] The Chinese patent with the publication number of CN209173622U discloses a spray tower, which includes a spray tower body and a circulating water tank. The spray tower body includes a spray tower tower body and a spray tower tower cover. The top of the spray tower tower cover is provided with an equipment inlet and outlet coaxial with the spray tower tower cover, and an observation hole is provided on the side wall of the spray tower tower cover; on the side wall of the spray tower tower body, there are more than or equal to 2 observation holes arranged axially from top to bottom along the spray tower tower body, and an equipment inlet and outlet is provided at the lower end of the side wall of the spray tower tower body; the circulating water tank includes a box body and a circulating water pump. A partition plate and a permeable grille are arranged in the box body. The partition plate is arranged directly above the permeable grille and the lower end of the partition plate is connected to the upper end of the permeable grille. The partition plate and the permeable grille divide the box body into a reflux chamber and a water pump chamber.

[0004] Although the above scheme effectively improves the amount of spray liquid pumped out by the circulating water pump per unit time, when the spray tower is working, the operation of the fan will generate negative pressure, extract the gas inside the tower body, and discharge it through subsequent treatment equipment. When the fan stops, this negative pressure effect disappears, and the gas inside the tower body will expand or contract due to temperature difference, humidity change or external air pressure, resulting in a temporary increase in the air pressure inside the tower body. There is no proper ventilation hole at the connection between the water tank of this spray tower and the tower body. This air pressure change may prevent the water from flowing smoothly back to the water tank from the tower body, resulting in the water in the water tank being pressed into the tank by the external air pressure, causing the water level in the water tank to rise and leak from the water tank cover. Therefore, it does not meet the existing requirements. For this reason, we propose a spray tower for preventing water leakage of the water tank. Content of the Utility Model

[0005] The purpose of the utility model is to provide a spray tower for preventing water leakage of the water tank, so as to solve the problem that there is no ventilation hole between the tower body and the water tank of the spray tower, resulting in the water level in the water tank rising and leaking from the water tank cover when the fan stops as mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A spray tower for preventing water leakage in a waterproof box, comprising a tower body and a water tank. The water tank is arranged on one side of the tower body and is communicated with the tower body. Two spray pipes are installed at the upper end inside the tower body. A water pump is arranged at the upper end of the water tank. The water pump is connected to the spray pipes and the water tank through connecting pipes respectively;

[0007] It further includes an adjustment box which is arranged above the water tank and is connected to the tower body. A threaded rod is rotatably arranged at the front side inside the adjustment box. An L-shaped moving block is threadedly connected to the outer part of the threaded rod. A ventilation hole is opened at the lower side of one side inside the tower body. A storage groove is opened at the upper end of the ventilation hole. One end of the L-shaped moving block penetrates and extends into the inside of the storage groove, and the L-shaped moving block is slidably matched with the storage groove;

[0008] It further includes a low liquid level sensor which is arranged at one side inside the water tank and is connected to the tower body.

[0009] Preferably, a motor is installed at the front side of the upper end of the adjustment box, and the output end of the motor is in transmission connection with the threaded rod through a coupling.

[0010] Preferably, a guide rod is welded at the rear side inside the adjustment box. The guide rod penetrates through the L-shaped moving block, and the guide rod is slidably matched with the L-shaped moving block.

[0011] Preferably, a baffle is arranged at one end of the L-shaped moving block located inside the storage groove, and the baffle is slidably matched with the storage groove.

[0012] Preferably, a clamping groove is opened at the lower end of the ventilation hole. One end of the baffle extends into the inside of the clamping groove, and the clamping groove is adapted to the baffle.

[0013] Preferably, a rubber block is adhesively fixed at one end of the baffle located inside the clamping groove.

[0014] Preferably, a PLC controller is installed on one side of the water tank. The input end of the PLC controller is electrically connected to the output end of the low liquid level sensor. A liquid infusion pipe is arranged below the PLC controller. An electric valve is arranged at one end of the liquid infusion pipe, and the input end of the electric valve is electrically connected to the output end of the PLC controller.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. The utility model is provided with a ventilation hole at the lower side of one side of the tower body. When the external fan is turned off, the motor is started. The motor drives the threaded rod to rotate, thereby driving the L-shaped moving block to move up and down. The L-shaped moving block drives the baffle plate to move up synchronously, so that the L-shaped moving block moves into the interior of the storage groove. At this time, the ventilation hole is opened, making the negative pressure in the water tank the same as that inside the tower body, enabling the water to flow smoothly back into the water tank from the tower body, avoiding the problem that the water in the water tank is pressed into the tank by the external air pressure, resulting in the water level in the water tank rising and leaking from the water tank cover.

[0017] 2. The utility model is provided with a low liquid level sensor on one side inside the water tank. When spraying operation is carried out in the spray tower, the water is atomized into fine particles through the nozzle. During the process of these particles contacting the waste gas, some of them will be dispersed outside the tower due to the action of the air flow, thus causing the water level to drop. When the water level drops to a position where it cannot be pumped by the water pump, it will be detected by the low liquid level sensor. The low liquid level sensor sends an electrical signal to the PLC controller, and the PLC controller starts the electric valve for a period of time, enabling the external water flow to enter the water tank through the infusion pipe, completing the automatic water replenishment operation without the need for manual regular water replenishment, and having good practicability.

[0018] 3. The utility model has a rubber block adhesively fixed at the lower end of the baffle plate. When the external fan is started, at this time, the rotation of the motor can make the L-shaped moving block move downward, thereby driving the baffle plate to be clamped into the interior of the card slot, increasing the sealing performance through the rubber block. At this time, the fan operates normally, and the ventilation opening can remain closed, reducing the influence of the external air on the interior of the tower body.

Detailed Description of the Invention

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a spray tower for preventing water leakage in a waterproof box, including a tower body 1 and a water tank 2. The water tank 2 is arranged on one side of the tower body 1 and is communicated with the tower body 1. Two spray pipes 18 are installed at the upper end inside the tower body 1. A water pump 16 is arranged at the upper end of the water tank 2. The water pump 16 is connected to the spray pipes 18 and the water tank 2 through connecting pipes 17 respectively;

[0026] It further includes an adjustment box 3, which is arranged above the water tank 2 and is connected to the tower body 1. A threaded rod 5 is rotatably arranged on the front side inside the adjustment box 3. An L-shaped moving block 6 is threadedly connected to the outside of the threaded rod 5. A ventilation hole 8 is opened at the lower side of one side inside the tower body 1. A storage groove 9 is opened at the upper end of the ventilation hole 8. One end of the L-shaped moving block 6 penetrates and extends into the inside of the storage groove 9, and the L-shaped moving block 6 is slidably matched with the storage groove 9;

[0027] It further includes a low-level liquid sensor 12, which is arranged on one side inside the water tank 2 and is connected to the tower body 1.

[0028] During use, start the fan to make the waste gas flow inside the tower body 1. At the same time, the water pump 16 sends water into the spray pipes 18 through the connecting pipes 17 for spraying. The motor 4 drives the threaded rod 5 to rotate, driving the L-shaped moving block 6 to move vertically under the restriction of the guide rod 7, and then pushing the baffle 10 into the card slot 19, enhancing the seal through the rubber block 11 to reduce external air interference. When shutting down, the motor 4 rotates in reverse to retract the baffle 10 into the storage groove 9, and the ventilation hole 8 is opened to keep the air pressure balance between the water tank 2 and the inside of the tower body 1, ensuring that the water can flow back smoothly and preventing the water tank 2 from overflowing due to the air pressure difference. In addition, the low-level liquid sensor 12 monitors the water level in the water tank 2. When it is lower than the set value, the PLC controller 13 starts the electric valve 14 to automatically replenish water through the infusion pipe 15.

[0029] Please refer to Figure 1 , Figure 2 and Figure 3 , a motor 4 is installed on the front side of the upper end of the adjustment box 3, and the output end of the motor 4 is in transmission connection with the threaded rod 5 through a coupling. The power of the motor 4 can be efficiently and stably transmitted to the threaded rod 5, thereby driving the L-shaped moving block 6 to achieve precise position adjustment;

[0030] Please refer to Figure 3, a guide rod 7 is welded to the rear side inside the adjustment box 3. The guide rod 7 passes through the L-shaped moving block 6, and the guide rod 7 is slidably matched with the L-shaped moving block 6. The guide rod 7 provides a stable movement track for the L-shaped moving block 6, avoiding deviation or shaking during its movement;

[0031] Please refer to Figure 4 , one end of the L-shaped moving block 6 located inside the storage groove 9 is provided with a baffle 10, and the baffle 10 is slidably matched with the storage groove 9. The design of the storage groove 9 enables the baffle 10 to be compactly stored without performing a sealing operation, without occupying extra space, making the entire device structure more compact and reasonable;

[0032] Please refer to Figure 4 , a card slot 19 is opened at the lower end of the ventilation hole 8. One end of the baffle 10 extends into the interior of the card slot 19, and the card slot 19 is adapted to the baffle 10. The tight fit between the card slot 19 and the baffle 10 further enhances the sealing effect and effectively prevents the influence of external air on the interior of the tower body;

[0033] Please refer to Figure 4 , a rubber block 11 is adhesively fixed to one end of the baffle 10 located inside the card slot 19. The rubber block 11 can not only effectively reduce the friction and wear between the baffle 10 and the card slot 19, extending the service life, but also further improve the sealing effect due to its good elasticity and sealing performance, ensuring the stability of the internal environment of the tower body 1;

[0034] Please refer to Figure 1 and Figure 2 , a PLC controller 13 is installed on one side of the water tank 2, and the input end of the PLC controller 13 is electrically connected to the output end of the low liquid level sensor 12. A liquid delivery pipe 15 is arranged below the PLC controller 13. One end of the liquid delivery pipe 15 is provided with an electric valve 14, and the input end of the electric valve 14 is electrically connected to the output end of the PLC controller 13. When the water level is lower than the set value, the PLC controller 13 can automatically start the electric valve 14 to replenish water into the water tank through the liquid delivery pipe 15 without manual intervention, realizing the automatic replenishment of the water level in the water tank 2.

[0035] Working principle: When in use, start the external fan. When the exhaust gas flows in the tower body 1, start the water pump 16. Through the connecting pipe 17, the water in the water tank enters the spray pipe 18 for spraying operation. At this time, start the motor 4, and through the coupling, the threaded rod 5 rotates synchronously. The threaded rod 5 drives the L-shaped moving block 6 to rotate synchronously. Due to the guiding effect of the guiding rod 7, the L-shaped moving block 6 can be axially limited. The rotation of the L-shaped moving block 6 is converted into vertical up and down movement, so that the baffle 10 can be driven to move down, and the baffle 10 is clamped into the inside of the clamping groove 19. The rubber block 11 reduces the wear of the baffle 10 and increases the sealing performance at the same time, thereby reducing the influence of the external air on the inside of the tower body 1. When the fan is stopped, reverse the motor 4. At this time, the threaded rod 5 drives the L-shaped moving block 6 to move up, so that the baffle 10 can be driven into the storage groove 9. At this time, the ventilation hole 8 can be opened, so that the negative pressure in the water tank 2 is the same as that inside the tower body 1, and the water can flow back from the tower body 1 to the water tank 2 smoothly, avoiding the problem that the water in the water tank 2 is pressed into by the external air pressure, causing the water level in the water tank 2 to rise and leak from the cover plate of the water tank 2. During daily use, the low-level sensor 12 can monitor the water level in the water tank. When the water level drops to a position where it cannot be pumped by the water pump 16, it will be detected by the low-level sensor 12. The low-level sensor 12 will send an electrical signal to the PLC controller 13. After processing, the PLC controller 13 will start the electric valve 14 for a period of time. After the electric valve 14 is started, the external water flow will enter the inside of the water tank 2 through the infusion pipe 15, completing the automatic water replenishment of the water tank 2 without manual regular water replenishment, and it has good practicability.
