Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and more specifically to an automatic cooling device for a nitric acid dilution tank. Background Technology

[0002] During the dilution of concentrated and dilute nitric acid, a large amount of heat is released, causing the temperature of the nitric acid dilution tank to rise rapidly, necessitating cooling. Cooling devices are commonly used in modern life and industrial production, primarily in glass processing, catalyst preparation, silica gel manufacturing, and pharmaceutical production.

[0003] However, existing cooling devices are usually operated manually, with a low degree of automation, which makes them prone to operational errors.

[0004] Therefore, providing an automatic cooling device for nitric acid dilution tanks is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an automatic cooling device for a nitric acid dilution tank to solve the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic cooling device for a nitric acid dilution tank includes a nitric acid dilution tank, a dilute nitric acid storage tank, a concentrated nitric acid storage tank, a temperature control switch, a spray cooling system, and a spray pneumatic shut-off valve. The dilute nitric acid storage tank is connected to the nitric acid dilution tank via a first delivery pipeline; the concentrated nitric acid storage tank is connected to the nitric acid dilution tank via a second delivery pipeline; the temperature control switch is installed on the nitric acid dilution tank; the spray cooling system is aligned with the nitric acid dilution tank; the spray pneumatic shut-off valve is installed on the spray pipe of the spray cooling system; and the temperature control switch is electrically connected to the spray pneumatic shut-off valve.

[0008] By adopting the above technical solutions, the beneficial effects of this utility model are as follows:

[0009] It can control the spray cooling in real time according to the temperature of the nitric acid dilution tank, realize automation, reduce labor intensity, and save energy and reduce consumption.

[0010] Furthermore, the first and second delivery pipelines have the same structure, both including a delivery pipe, a pump, and a pneumatic shut-off valve, with the pump and the pneumatic shut-off valve both installed on the delivery pipe. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figure 1 As shown in the figure, this utility model discloses an automatic cooling device for a nitric acid dilution tank, including a nitric acid dilution tank 1, a dilute nitric acid storage tank 2, a concentrated nitric acid storage tank 3, a temperature control switch 4, a spray cooling system 5, and a spray pneumatic shut-off valve 6. The dilute nitric acid storage tank 2 is connected to the nitric acid dilution tank 1 via a first conveying pipeline 7; the concentrated nitric acid storage tank 3 is connected to the nitric acid dilution tank 1 via a second conveying pipeline 8; the temperature control switch 4 is installed on the nitric acid dilution tank 1; the spray cooling system 5 is aligned with the nitric acid dilution tank 1; the spray pneumatic shut-off valve 6 is installed on the spray pipe of the spray cooling system 5; the temperature control switch 4 and the spray pneumatic shut-off valve 6 are electrically connected. This utility model can control the spray cooling in real time according to the temperature of the nitric acid dilution tank 1, realizing automation, reducing labor intensity, and saving energy and consumption.

[0015] Specifically, the first conveying pipeline 7 and the second conveying pipeline 8 have the same structure, both including a conveying pipe 71, a pump 72 and a pneumatic shut-off valve 73, with the pump 72 and the pneumatic shut-off valve 73 both installed on the conveying pipe 71.

[0016] The working principle of this utility model:

[0017] Under normal non-acid mixing conditions, the spray pneumatic shut-off valve 6 is closed by default. Dilute nitric acid (20% nitric acid) in dilute nitric acid storage tank 2 is pumped to nitric acid dilution tank 1 via pump 72. When the temperature of nitric acid dilution tank 1 reaches 40 degrees Celsius, the temperature control switch 4 sends a signal to control the spray pneumatic shut-off valve 6 to start. When the temperature of concentrated nitric acid (98% nitric acid) in concentrated nitric acid storage tank 3 rises too quickly after entering nitric acid dilution tank 1, the spray pneumatic shut-off valve 6 opens wider. When the temperature of nitric acid dilution tank 1 is less than 58 degrees Celsius and remains below 58 degrees Celsius for 10 seconds, and stops rising, the temperature control switch 4 sends a signal to control the spray pneumatic shut-off valve 6 to stop operating.
