Technical Field
[0001] This utility model relates to the field of hazardous waste treatment equipment, specifically to an organic waste liquid mixing device. Background Technology

Detailed Implementation
[0018] The present invention will be further described below through specific embodiments.
[0019] like Figure 1 As shown, the organic waste liquid mixing device of this utility model includes a negative pressure mixing unit 1, an absorption unit 2 and a support 3. The absorption unit 2 is placed on one side of the negative pressure mixing unit 1, and both the negative pressure mixing unit 1 and the absorption unit 2 are fixedly connected to the support 3.
[0020] like Figure 1 and Figure 2 As shown, the negative pressure mixing unit 1 of this utility model includes a negative pressure reaction tank 11, a tank cover 12, a liquid inlet pipe 13, a discharge port 14, a negative pressure suction pipe 15, a pressure balance port 16, a liquid level gauge 17, and a pressure sensor 18. The negative pressure reaction tank 11 is an upward-opening, corrosion-resistant pressure-bearing tank that can accept organic waste liquid for mixing. The tank cover 12 is sealed and detachably fixed to the opening of the negative pressure reaction tank 11, and is pressure-bearing and corrosion-resistant. The inlet pipe 13 is a corrosion-resistant pipe with an electric control valve. Several inlet pipes 13 are fixed to the tank cover 12, and their lower ends are inserted into the upper part of the negative pressure reaction tank 11. The outlet port 14 is a corrosion-resistant pipe with an electric control valve. The upper end of the outlet port 14 is fixed to the bottom of the negative pressure reaction tank 11 and communicates with its inner cavity. The negative pressure suction pipe 15 is a corrosion-resistant pipe with an electric control valve. One end of the negative pressure suction pipe 15 is fixed to the upper part of the negative pressure reaction tank 11 and communicates with its inner cavity. The other end of the negative pressure suction pipe 15 is connected to an external negative pressure vacuum pump. The pressure balance port 16 is a corrosion-resistant pipe with an electric control valve. The lower end of the pressure balance port 16 is fixed to the tank cover 12 and communicates with its inner cavity. The level gauge 17 is placed in the middle of the negative pressure reaction tank 11 and fixed to the tank wall of the negative pressure reaction tank 11. The pressure sensor 18 is arranged in the upper part of the inner cavity of the negative pressure reaction tank 11 and fixed to the tank cover 12. The level gauge 17 and the pressure sensor 18 can automatically detect the liquid level and pressure inside the negative pressure reaction tank 11, respectively.
[0021] like Figures 1 to 3As shown, the absorption unit 2 of this utility model includes a water tank 21 and a waste gas collection pipe 22. The water tank 21 is equipped with a tank cover and a drain outlet with a valve. The tank cover is locked to the opening of the water tank 21, and the drain outlet is fixed to the bottom of the water tank 21. The waste gas collection pipe 22 is a corrosion-resistant pipe and is equipped with an electric control valve and a blower. The waste gas collection pipe 22 is Π-shaped, with one end inserted into the liquid water in the water tank 21, and the other end placed in the upper part of the negative pressure reaction tank 11, with a funnel-shaped gas collection hood at that end. The waste gas collection pipe 22 is fixed to the tank cover of the water tank 21. The waste gas collection pipe 22 can send the gas volatilized in the negative pressure reaction tank 11 to the liquid water stored in the water tank 21 of the absorption unit 2 for absorption.
[0022] The organic waste liquid mixing device further includes an electrical control system, which is equipped with a control module, a power supply and control buttons. The electric control valves installed on the inlet pipe 13, the outlet 14, the negative pressure suction pipe 15, the air pressure balance port 16 and the waste gas collection pipe 22 are all electrically connected to the electrical control system. The air pump installed on the waste gas collection pipe 22 is electrically connected to the electrical control system. The liquid level gauge 17 and the air pressure sensor 18 are electrically connected to the electrical control system. The electronic control system can be set with warning values and maximum liquid level values for intervention if the pressure of the organic waste liquid in the negative pressure reaction tank 11 rises abnormally during mixing. The electronic control system can receive and analyze the pressure and liquid level information in the negative pressure reaction tank 11 collected by the pressure sensor 18 and the liquid level gauge 17. It can also command the electric control valves installed on the inlet pipe 13, the outlet 14, the negative pressure suction pipe 15, the pressure balance port 16, and the waste gas collection pipe 22, as well as the air pump installed on the waste gas collection pipe 22, to operate.
[0023] Before using this device, the electrical control system should be set with warning values and maximum liquid level values for intervention should an abnormal increase in pressure occur during the mixing of organic waste liquid in the negative pressure reaction tank 11. Then, the electrical control system should instruct all electrically controlled valves on the inlet pipe 13, outlet 14, pressure balance port 16, and waste gas collection pipe 22 to close. The electrically controlled valve on the negative pressure suction pipe 15 and the externally connected negative pressure vacuum pump should be opened to create a negative pressure state inside the negative pressure reaction tank 11. Finally, the electrically controlled valve on the negative pressure suction pipe 15 should be closed, and the inlet pipe 13 should be opened. The electric control valve allows the organic waste liquid and other chemical agents to be mixed to be sent into the negative pressure reaction tank 11 through different inlet pipes 13 and by the negative pressure inside the negative pressure reaction tank 11 or by a delivery pump connected to the outside of the inlet pipe 13 for mixing. During the mixing process, due to the complex composition of the waste liquid, some of it may undergo violent chemical reactions, resulting in high temperature and high pressure, gas explosion or dense smoke in the negative pressure reaction tank 11. The pressure sensor 18 will collect the pressure information in the negative pressure reaction tank 11 in real time and feed the collected pressure information back to the electronic control system for analysis and processing.
[0024] If the negative pressure inside the negative pressure reactor 11 cannot overcome the enormous pressure generated by the violent chemical reaction, and the pressure value inside the negative pressure reactor 11 rises abnormally and reaches the set warning value, the electronic control system will instruct the electric control valve on the inlet pipe 13 to close, stopping the liquid mixing process. It will also instruct the electric control valve on the exhaust gas collection pipe 22 and the air pump to release gas and relieve pressure; the released gas will be absorbed by the water in the water tank 21. If the pressure value inside the negative pressure reactor 11 does not reach the warning value, but the liquid level of the mixed liquid inside the negative pressure reactor 11 reaches the set maximum liquid level, the electronic control system will also instruct the electric control valve on the inlet pipe 13 to close, and then instruct the electric control valve on the pressure balance port 16, the electric control valve on the exhaust gas collection pipe 22, and the air pump to open simultaneously. The gas volatilized during the mixing process in the negative pressure reactor 11 will be discharged into the water in the water tank 21 for absorption by the exhaust gas collection pipe 22; the mixed liquid will then be discharged and collected from the outlet 14.
[0025] The organic waste liquid mixing device of this utility model is configured with a negative pressure mixing unit 1 and an absorption unit 2. A negative pressure suction pipe 15, a liquid level gauge 17, and a pressure sensor 18 are installed on the negative pressure reaction tank 11 of the negative pressure mixing unit 1. A waste gas collection pipe 22 is installed on the water tank 21 of the absorption unit 2. The sealed negative pressure cavity of the negative pressure reaction tank 11, which is fixed with a tank cover 12, and the pressure sensor 18, which automatically detects the pressure, are used to prevent gas explosions during the mixing of organic waste liquid. The waste gas collection pipe 22 of the absorption unit 2 is used to send the gas volatilized in the negative pressure reaction tank 11 to the water stored in the water tank 21 of the absorption unit 2 for absorption. This can avoid the risk of impacting the surrounding environment and causing harm to operators during the mixing of organic waste liquid.
[0026] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
