Description

Technical Field

[0001] This utility model relates to the field of acid storage tank technology, and in particular to an anti-clogging device for the drain outlet of an acid storage tank. Background Technology

[0002] After passing through a wet flue gas purification system, the flue gas from non-ferrous metallurgical processes is transported to downstream flue gas treatment processes. During the wet treatment process, a storage tank is needed to temporarily store the acid solution for acid circulation. Since the acid solution used to wash the flue gas contains a lot of impurities, these impurities will settle and accumulate at the bottom of the storage tank when stored in the acid solution, affecting the normal circulation of the acid solution. Currently, manual stirring is often used to clean the settled impurities near the drain outlet of the acid solution storage tank, which is time-consuming and labor-intensive. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an anti-clogging device for the drain outlet of an acid storage tank, which solves the problem of impurities settling and accumulating and clogging the drain outlet of the storage tank when the acid is stored in the tank.

[0004] To achieve the above objectives, the specific technical solution of this utility model is as follows: An anti-clogging device for the drain outlet of an acid storage tank includes a storage tank and a drain outlet installed at the bottom of the storage tank. An air inlet main pipe is provided at the top of the storage tank, and several air supply pipes connected to it are vertically installed on the air inlet main pipe. The air supply pipes are inserted into the storage tank, and the air outlet of the air supply pipes is located at the bottom of the storage tank.

[0005] As a further improvement of this utility model, the outlet of the gas pipe has a flared structure.

[0006] As a further improvement of this utility model, a valve for controlling its opening and closing is installed at the outlet of the gas pipeline.

[0007] As a further improvement of this utility model, a valve is installed on the intake manifold.

[0008] As a further improvement of this utility model, the air inlet of the valve is connected to the air source through a quick-connect coupling.

[0009] The beneficial effects of this utility model are as follows: 1. By installing several gas supply pipes connected to the main air inlet pipe at the bottom of the storage tank, airflow can be used to blow air onto the sediment at the bottom of the storage tank, effectively solving the problem of impurities settling and accumulating and clogging the drain outlet during acid storage.

[0010] 2. The flared outlet structure can expand the gas spray area, enhance the impact on the deposits in the surrounding acid, make it more difficult for the deposits to accumulate at the drain outlet, and improve the anti-clogging effect.

[0011] 3. The spring-loaded check valve installed at the gas outlet of the gas pipeline can realize one-way gas flow, avoid corrosion caused by acid backflow into the gas pipeline when the gas supply is stopped, and at the same time prevent impurities in the acid from entering the gas pipeline and causing internal blockage. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] In the diagram, 1 is a quick-connect fitting; 2 is a valve; 3 is a gas supply pipe; 4 is a storage tank; 5 is a main gas inlet pipe; 6 is a drain port; and 7 is a check valve. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0015] like Figure 1 As shown, an anti-clogging device for the drain outlet of an acid storage tank includes a storage tank 4 and a drain outlet 6 installed at the bottom of the storage tank 4. An air inlet main pipe 5 is provided at the top of the storage tank 4, and several air supply pipes 3 connected to it are vertically installed on the air inlet main pipe 5. The air supply pipes 3 are inserted into the storage tank 4, and the air outlet of the air supply pipes 3 is located at the bottom of the storage tank 4. By setting several air supply pipes 3 in the storage tank 4, airflow can be used to blow air onto the sediment at the bottom of the storage tank 4, effectively solving the problem of impurities settling and clogging the drain outlet 6 during acid storage.

[0016] The outlet of the gas pipe 3 has a flared structure, and a spring-loaded one-way valve 7 is installed at the outlet of the gas pipe 3. The flared structure of the outlet can expand the gas spray area, enhance the impact strength on the deposits in the surrounding acid, make it more difficult for the deposits to accumulate at the drain port, and improve the anti-clogging effect. The spring-loaded one-way valve 7 can realize one-way gas flow, prevent acid from flowing back into the gas pipe 3 and causing corrosion when the gas is stopped, and also prevent impurities in the acid from entering the gas pipe 3 and causing internal blockage.

[0017] In use: The worker opens valve 2, and the gas is delivered to the bottom of the storage tank 4 through the main air inlet pipe 5 and the gas delivery pipe 3. After being diffused by the flared structure, it is sprayed out, which blows away the sediment and impurities near the drain outlet 6, preventing the impurities from settling at the drain outlet 6. At this time, the spring-loaded one-way valve 7 remains open in one direction, allowing only gas to enter the acid solution and preventing acid backflow. When stopping the machine, valve 2 is closed to cut off the gas supply, and the spring-loaded one-way valve 7 closes. This utility model is simple to operate and responds promptly, and can effectively solve the problem of impurities settling and accumulating and clogging the drain outlet when storing acid solution.

[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
