Description

Technical Field

[0001] This utility model relates to a dissolving device, specifically an air-pump dissolving device, belonging to the field of solvent processing equipment. Background Technology

[0002] In various factory chemical dosing processes, using agitators to rapidly mix chemicals is a routine and crucial technique. However, in practice, due to limitations in the agitator's precision and inaccuracies in its compatibility with the dosing equipment, dead zones often form during mixing, causing some chemicals to deposit unevenly. If these deposited chemicals are not addressed promptly, they will adversely affect subsequent physical and chemical reactions, ultimately impacting the overall reaction outcome.

[0003] This problem is particularly prominent in the water supply industry, as it is a crucial link in the production and supply of tap water and has extremely strict quality control requirements for every stage of water treatment. In conventional tap water treatment processes, coagulants are usually added artificially to promote the effective separation of impurities from the water.

[0004] However, in actual production operations, because dissolution tanks are typically designed in a rectangular shape and use agitators for mixing and dissolving, there are often blind spots in the corners. At the same time, there is a certain height difference between the bottom of the dissolution tank and the agitator, making it difficult for the chemicals deposited at the bottom to be fully stirred and dissolved, resulting in uneven chemical concentrations and consequently, inaccurate dosage, which affects the quality of the effluent.

[0005] In addition, droplets generated during the stirring process sometimes splash out of the dissolving tank, which not only causes dirt and pollution in the dosing room, but also has an adverse effect on the cleanliness and aesthetics of the overall environment. Utility Model Content

[0006] In view of this, the present invention provides an air-pumping dissolving device to solve the above-mentioned problems in the prior art.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] An air-flushing dissolving device includes a control module and at least one set of aeration main pipes. The air inlet of the aeration main pipe is connected to a blower through a blower outlet electric valve. The control module is communicatively connected to the blower outlet electric valve and an electric switching valve. The portion of the aeration main pipe located inside the dissolving tank has aeration holes.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the two adjacent aeration main pipes are connected by an electric switching valve, and the portion located in the dissolution tank is connected by an aeration branch pipe, which has aeration holes.

[0011] Furthermore, it also includes a dilution water pipe, the outlet of which is located inside the dissolving tank. Preferably, the outlet of the dilution water pipe is equipped with a dilution water electric valve that is communicatively connected to the control module.

[0018] 1. Aeration main pipe, 2. Electric valve for blower outlet, 3. Blower, 4. Electric switching valve, 5. Aeration branch pipe, 6. Dilution water pipe, 7. Electric valve for dilution water, 8. Splash guard. Detailed Implementation

[0019] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0020] Example 1

[0021] like Figure 1 As shown, the air-flushing dissolving device includes a control module and at least one set of aeration main pipes 1. The air inlet of the aeration main pipe 1 is connected to a blower 3 through a blower outlet electric valve 2. The control module is communicatively connected to the blower outlet electric valve 2 and the electric switching valve 4 respectively. The portion of the aeration main pipe 1 located inside the dissolving tank has aeration holes.

[0022] In this embodiment, there are two sets of aeration main pipes 1, which are arranged in parallel and connected by an electric switching valve 4. The part located in the dissolving tank is connected by an aeration branch pipe 5, and an aeration hole is provided on the aeration branch pipe 5.

[0023] In another embodiment of this invention, a dilution water pipe 6 is also included, with the outlet end of the dilution water pipe 6 located inside the dissolving tank.

[0024] Numerous tiny aeration holes are distributed on the surface of the main aeration pipe 1 and the branch aeration pipe 5. When the blower 3 is started, air is transported to the dissolving tank through the pipe and slowly released through the small holes on the pipe, forming a series of fine bubbles at the bottom of the tank. The disturbance effect of these bubbles greatly promotes the full dissolution of the agent. At the same time, the air flushing intensity is adjusted by adjusting the number of blowers 3 and the air volume of each blower 3 to ensure the dissolution effect. In addition, air flushing between different dissolving tanks can be achieved by controlling the opening and closing of the outlet electric valve and the electric switching valve 4.

[0025] Example 2

[0026] like Figure 2 As shown, the air-pump dissolving device includes a control module and a set of aeration main pipes 1. The air inlet of the aeration main pipe 1 is connected to the blower 3 through the blower outlet electric valve 2. The control module is communicatively connected to the blower outlet electric valve 2 and the electric switching valve 4 respectively. The aeration main pipe 1 has aeration holes on the part set in the dissolving tank.

[0027] It also includes a dilution water pipe 6, the outlet of which is located inside the dissolving tank. The outlet of the dilution water pipe 6 is equipped with a dilution water electric valve 7 that is connected to the control module. It also includes a splash guard 8 located on the outer side of the dissolving tank.

[0028] In this embodiment, the splash guard 8 is a transparent glass cover.

[0029] The splash guard 8 ensures safety and hygiene during the mixing process, effectively preventing splashing of liquid droplets that may be generated during mixing, thus ensuring a clean and aesthetically pleasing operating environment. At the same time, using a transparent glass cover as the splash guard 8 allows operators to clearly observe the working status inside the dissolving tank, facilitating monitoring and management.

[0030] Example 3

[0031] The method for dissolving polyaluminum chloride using the air-pump dissolving device in Example 2 is as follows:

[0032] (1) Open the electric valve 7 for dilution water through the control module, inject water into the dissolving tank, and determine the injection volume according to the level gauge;

[0033] (2) Close the electric valve 7 for dilution water and add polyaluminum chloride according to the predetermined concentration;

[0034] (3) Start the blower 3 and open the blower outlet electric valve 2 to start air jet mixing;

[0035] (4) Open the dilution water electric valve 7 again, inject clean water to the predetermined level, and then close the valve;

[0036] (5) Observe the dissolution in the dissolving tank, and after mixing evenly, close the blower 3 and the blower outlet electric valve 2.

[0037] Based on the above operations, control programs can be preset in the control module to automate operations other than adding chemicals, such as automatic start and stop of the dilution water electric valve 7, synchronous start and stop of blower 3 and blower 3 outlet valve, and automatic opening and closing of the electric switching valve 4 between the aeration main pipe 1.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
