Description

Technical Field

[0001] This utility model relates to the technical field of ammonia tank equipment, specifically an ammonia tank overflow backwashing device. Background Technology

[0002] In actual use of ammonia tanks, existing overflow devices generally have two major problems: First, the overflow pipes of ammonia tanks are prone to crystallization and blockage, causing the overflow function to fail. The ammonia tank cannot overflow and refresh the tank liquid normally, thus shortening the service life of the tank liquid and affecting the overall operating efficiency of the ammonia tank. Second, during maintenance and cleaning of existing devices, crystallized impurities in the overflow pipes cannot be effectively removed, requiring frequent maintenance operations. Frequent maintenance will interfere with the normal production process, and dealing with blockages can easily lead to a deterioration in the appearance quality of the products, reducing the overall operational stability of the production line. Summary of the Invention

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an ammonia tank overflow backwashing device, which is equipped with an overflow component and a circulation component that can switch working states, and works in conjunction with a liquid level detection component. This solves the problems of easy crystallization and blockage in the overflow pipes of existing ammonia tanks, and the impact of frequent maintenance on production and product quality.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an ammonia tank overflow backwashing device, comprising an ammonia tank assembly, wherein the ammonia tank assembly is equipped with a liquid level detection assembly, an overflow assembly, and a circulation assembly.

[0005] The ammonia tank assembly includes a tank body. Two first pipe grooves are symmetrically arranged on one side of the tank body, and a second pipe groove is symmetrically arranged on the other side. The symmetrical design of the first and second pipe grooves provides a neat installation space for the overflow pipe and the circulation pipe, respectively, avoiding maintenance difficulties caused by messy pipes, while ensuring the sealing of the connection between the pipes and the tank body to prevent ammonia leakage.

[0006] The liquid level detection component includes a liquid level sensor located inside the water tank. A data transmitter is installed at the bottom of the liquid level sensor, and a data transmission port is installed at the front end of the data transmitter. The liquid level sensor can monitor the liquid level in the water tank in real time. The data transmitter and the data transmission port work together to transmit the liquid level data to an external terminal in a timely manner, so that the staff can keep track of the liquid level in the tank in real time and avoid the liquid level being too high or too low, which would affect production.

[0007] The overflow assembly includes an overflow pipe fixedly installed in the first pipe groove. The bottom ends of both overflow pipes are connected to an overflow discharge pipe, and the other ends of both overflow pipes are connected to the same three-way control valve. An overflow discharge control valve is fixedly installed at the port at the bottom end of the overflow discharge pipe. The overflow pipe and the overflow discharge pipe form a basic overflow path. The cooperation between the three-way control valve and the overflow discharge control valve can realize the on / off control of the overflow path, providing a basis for subsequent backwashing state switching.

[0008] The circulation assembly includes a first circulation pipe fixedly installed in the upper second pipe trench and a second circulation pipe fixedly installed in the lower second pipe trench. The other end of the first circulation pipe is connected to a backwash control valve, and the other end of the backwash control valve is connected to a third circulation pipe. The third circulation pipe and the second circulation pipe are connected to the same circulation pump. The output end of the circulation pump is connected to the third circulation pipe. The third circulation pipe is connected to a three-way control valve through a backwash pipe, and a circulation control valve is provided on the third circulation pipe. Through the cooperation of multiple pipes and valves, the circulation assembly can realize liquid circulation under normal conditions and provide backwash power for the overflow pipe under backwash conditions. It uses the liquid in the water tank itself to complete the rinsing without the need to add additional rinsing media, thus reducing the cost of use.

[0009] As a further improvement of this utility model: a bracket is fixedly connected to the other side of the water tank, and the circulation pump is fixedly installed on the bracket; the bracket provides stable installation support for the circulation pump, avoids the vibration generated when the circulation pump is working, which may cause the pipeline connection to loosen, and ensures the stability of the circulation component operation.

[0010] As a further improvement of this utility model: an installation groove is provided at the center of the bottom of the water tank, and an installation seat is fixedly connected to the outer wall of the water tank. The installation seat has an installation hole. The installation groove provides installation space for the data transmitter. The installation seat and the installation hole cooperate to facilitate the connection of the entire device to the external fixed structure, improve the overall stability of the device installation, and adapt to the installation needs of different production scenarios.

[0011] As a further improvement of this utility model: the data transmitter is fixedly installed in the mounting groove, and both the data transmitter and the liquid level sensor are provided with an anti-corrosion coating on their outer sides; the anti-corrosion coating can effectively resist the corrosion of ammonia solution, extend the service life of the data transmitter and the liquid level sensor, avoid detection failures caused by corrosion, and ensure the reliability of the liquid level monitoring function.

[0012] As a further improvement of this utility model: the output pressure of the circulation pump is adjustable to adapt to the backwashing requirements of the overflow pipe with different degrees of blockage; the output pressure of the circulation pump is adjusted according to the severity of the overflow pipe blockage. When the blockage is mild, a lower pressure is sufficient to clear it, while when the blockage is severe, the pressure is increased to ensure the flushing effect, which saves energy and avoids damage to the pipeline caused by high pressure.

[0013] As a further improvement of this utility model: the inner walls of the overflow pipe, overflow discharge pipe, backwash pipe, and the first circulation pipe, second circulation pipe, and third circulation pipe are all provided with anti-corrosion coatings to resist the corrosion of ammonia solution; ammonia is highly corrosive, and the anti-corrosion coating on the inner wall can effectively delay the corrosion and aging of the pipeline, extend the service life of the pipeline, and reduce maintenance costs and production stoppages caused by pipeline damage.

[0014] As a further improvement of this utility model: the mounting holes are multiple and evenly distributed on the mounting base, and the mounting base is detachably connected to the external fixing structure through the mounting holes; the multiple evenly distributed mounting holes can enhance the stability of the connection between the mounting base and the external structure, and the detachable connection method facilitates the later maintenance, replacement and relocation of the device, thereby improving the practicality of the device.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by switching between multiple valves of the overflow component and the circulation component, the flexible switching between the two working states of conventional overflow and backwash anti-clogging is realized. The liquid is drawn by the circulation system of the water tank to backwash the overflow pipe, effectively removing the crystal blockage in the pipe. This solves the problem of easy blockage of the overflow pipe in the existing device, while extending the maintenance cycle and reducing the number of maintenance and cleaning times. It avoids the impact of blockage handling and frequent maintenance on production and product quality, and improves the overall operating efficiency of the production line.

[0016] 2. In this utility model, the liquid level in the water tank is monitored in real time by the liquid level detection component. Combined with the liquid circulation function of the circulation component under normal conditions, the liquid level in the tank is kept balanced and stable, ensuring the normal operation of the ammonia tank. At the same time, the pipe and tank design, bracket support and anti-corrosion coating of each component of the ammonia tank component improve the overall structural stability and corrosion resistance of the device, extend the service life of the device and reduce the later maintenance cost.

[0027] The circulation assembly 4 includes a first circulation pipe 41 fixedly installed in the upper second pipe groove 13 and a second circulation pipe 42 fixedly installed in the lower second pipe groove 13. The other end of the first circulation pipe 41 is connected to a backwash control valve 46, and the other end of the backwash control valve 46 is connected to a third circulation pipe 43. The third circulation pipe 43 and the second circulation pipe 42 are connected to the same circulation pump 44.

The third circulation pipe 43 is connected to a three-way control valve 33 through a backwash pipe 45, and a circulation control valve 47 is provided on the third circulation pipe 43. Through the cooperation of multiple pipes and valves, the circulation assembly 4 can realize liquid circulation under normal conditions and provide backwash power for the overflow pipe 31 under backwash conditions.

[0028] In the normal overflow state, the three-way control valve 33 is closed, the two overflow discharge control valves 34 are open, the circulation control valve 47 is closed, and the backwash control valve 46 is open. Excess liquid in the water tank 11 is discharged through the overflow pipe 31 and the overflow discharge pipe 32.

[0035] The working principle of this utility model is as follows: The device operates in two states. One is the normal overflow state, in which the three-way control valve 33 is closed, the two overflow discharge control valves 34 are open, the circulation control valve 47 is closed, and the backwash control valve 46 is open. Excess ammonia solution in the water tank 11 is discharged through the overflow pipe 31 and the overflow discharge pipe 32. At the same time, the circulation pump 44 is started, and the liquid flows back to the water tank 11 through the first circulation pipe 41, the backwash control valve 46, the third circulation pipe 43, and the second circulation pipe 42, realizing the liquid... The first is circulation; the second is backwashing and anti-clogging state. When the overflow pipe flow rate slows down or is blocked, the valve state is switched so that the three-way control valve 33 is opened, the two overflow discharge control valves 34 are closed, the circulation control valve 47 is opened, and the backwash control valve 46 is closed. The circulation pump 44 draws the liquid in the water tank 11 and enters the overflow pipe 31 through the first circulation pipe 41, the second circulation pipe 42, the third circulation pipe 43, the backwash pipe 45, and the three-way control valve 33 to backwash the inner wall of the overflow pipe 31 and remove the crystallized blockage.
