[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] By delivering nitrogen to the mixing tank for nitrogen sealing, additives and chemical raw materials are prevented from contacting with air, thus avoiding oxidation during the mixing process and ensuring product quality. Figure 1-4 As shown, a mixing device for chemical product additives described in the utility model comprises a mixing tank 1, a nitrogen sealing component 2, a feeding component 3 and a stirring component 4, wherein the nitrogen sealing component 2 is arranged on the outside of the mixing tank 1, and the nitrogen sealing component 2 comprises a nitrogen release valve 204 connected to one side of the mixing tank 1 through a pipeline and an air intake check valve 202 connected to the other side of the mixing tank 1 through a pipeline, the side of the nitrogen release valve 204 away from the mixing tank 1 is connected to a positive pressure buffer tank 201 through a pipeline, and the end of the air intake check valve 202 away from the mixing tank 1 is connected to a nitrogen supply valve 203 through a pipeline;

[0025] A feeding assembly 3 is provided on the top of the mixing tank 1, and the feeding assembly 3 includes a feeding pipe 301 which is penetrated and sleeved on one end of the top of the mixing tank 1, and a star-shaped discharger 304 is fixed to the top of the feeding pipe 301 by bolts. An arc tank 302 is welded to the bottom end of the feeding pipe 301 located inside the mixing tank 1, and a discharge pipe 303 is equidistantly connected to the bottom of the arc tank 302 through a threaded groove.

[0026] When in use, nitrogen flows into the mixing tank 1 through the nitrogen supply valve 203 and the air intake check valve 202, and nitrogen is sealed in the mixing tank 1 so that the chemical raw materials and additives will not come into contact with air when mixed. The nitrogen discharge valve 204 can be opened to discharge the nitrogen in the mixing tank 1 into the positive pressure buffer tank 201;

[0027] Open the star-shaped discharger 304 to allow additives and other auxiliary materials to flow into the arc-shaped tank 302 through the feed pipe 301, and then flow into the mixing tank 1 through multiple discharge pipes 303, so that they can be quantitatively and evenly added into the mixing tank 1.

[0028] In order to mix chemical raw materials and additives, for example, Figure 2 As shown, the utility model also includes that a stirring assembly 4 is arranged on the top of the mixing tank 1, and the stirring assembly 4 includes a variable frequency motor 401 installed on the top of the mixing tank 1 through a mounting frame, and the output shaft of the variable frequency motor 401 located inside the mixing tank 1 is connected to a stirring rod 402 through a connecting sleeve.

[0029] When in use, the variable frequency motor 401 is turned on to drive the stirring rod 402 to rotate, so as to stir and mix the chemical raw materials and additives in the mixing tank 1 .

[0030] For example, Figure 1 As shown, the utility model also includes that a liquid level meter 5 is installed at one end of the top of the mixing tank 1 away from the feed pipe 301 through a mounting frame, and the detection end of the liquid level meter 5 is located inside the mixing tank 1.

[0031] When in use, the liquid level meter 5 can detect the liquid level in the mixing tank 1 .

[0032] For example, Figure 1 As shown, the utility model also includes that an observation window 6 is provided on one side of the mixing tank 1, and a discharge valve 9 is connected to the bottom end of the mixing tank 1 through a threaded groove.

[0033] When in use, the setting of the observation window 6 enables personnel to visually see the mixing effect of the chemical raw materials and auxiliary materials such as additives in the mixing tank 1 , and the mixed chemical materials in the mixing tank 1 can be discharged by opening the discharge valve 9 .

[0034] For example, Figure 1 As shown, the utility model also includes that a temperature sensor 7 is installed at one end of the mixing tank 1 through a mounting seat, and a pressure gauge 8 is installed at one end of the mixing tank 1 located on the top of the temperature sensor 7 through a mounting frame, and the detection ends of the pressure gauge 8 and the temperature sensor 7 are both located inside the mixing tank 1.

[0036] When the utility model is used, a person uses a power cord to connect the device to an external power source and pours chemical raw materials into a mixing tank 1;

[0037] Turning on the variable frequency motor 401 can drive the stirring rod 402 to rotate, stirring the chemical raw materials in the mixing tank 1. Controlling the speed of the variable frequency motor 401 can slowly stir the raw materials. Turning on the star-shaped discharger 304 allows the additives and other auxiliary materials in the external hopper to flow into the arc tank 302 through the feed pipe 301, and then flow into the mixing tank 1 through multiple discharge pipes 303, so that the additives and other auxiliary materials are quantitatively, slowly and evenly added to the mixing tank 1. When the chemical raw materials are stirred, the additives and other auxiliary materials are evenly added to the mixing tank 1, thereby improving the mixing rate and mixing effect.

[0038] Open the nitrogen supply valve 203 to allow the nitrogen to flow into the mixing tank 1 through the air intake check valve 202. The air intake check valve 202 can prevent the nitrogen entering the mixing tank 1 from flowing back under pressure. The nitrogen entering the mixing tank 1 rises and stays at the top of the mixing tank 1 to perform nitrogen sealing, thereby preventing chemical raw materials, additives and other auxiliary materials from contacting with the air, thus avoiding oxidation during the mixing process and ensuring product quality. After the mixing is completed, open the nitrogen discharge valve 204 to allow the nitrogen in the mixing tank 1 to flow into the positive pressure buffer tank 201 and be discharged after meeting the standards.

[0039] At the same time, an observation window 6 is set on the mixing tank 1, which can intuitively see the mixing effect of the chemical raw materials and auxiliary materials such as additives in the mixing tank 1. The liquid level in the mixing tank 1 can be detected by the liquid level meter 5, the pressure gauge 8 can display the pressure in the mixing tank 1, and the temperature sensor 7 can display the temperature in the mixing tank 1.
