AI Technical Summary
In the production of pine pine, toxic gases are easily generated when mixing raw materials, which are discharged from the sealing part of the stirring shaft, causing harm to the operators and the environment.
A mixing device for the production of pine-killing pine, including a pressure vessel mixing tank with upper and lower seals, an agitator is installed on the top, and a vacuum pump is provided between the agitating shaft and the filler cap to form a negative pressure state to prevent the exhaust gas from coming out. The exhaust gas is adsorbed by activated carbon particles and is discharged, and the air pressure in the tank is balanced through an electric valve during discharge.
Effectively prevent the waste gas from the raw materials or finished products from being sent out from the stirring shaft, protecting the operator and the environment, and adsorbing harmful gases through activated carbon, improving the effect of waste gas treatment.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bentazone production, in particular to a mixing device for bentazone production. Background Art
[0002] In the production of bentazon, it is necessary to fully mix a dichloroethane solution of N-isopropyl anthranilamide with a mass concentration of 15% to 25% and a dichloroethane solution of 2-methylpyridinium sulfur trioxide complex in a stable environment at 20 to 30°C to react and synthesize bentazon. The raw materials and finished products of bentazon synthesis have certain toxicity and volatility. When the raw materials are stirred and mixed, toxic gases are easily discharged from the sealing part of the stirring shaft, causing harm to operators and the environment. Utility Model Content
[0003] In order to solve the problem of harm to human beings and the environment caused by mixing raw materials in the production of bentazone, the utility model provides a mixing device for the production of bentazone.
[0004] The technical solution provided by the utility model is: a mixing device for the production of bentazon, comprising a mixing tank, which is a pressure vessel with upper and lower heads, a stirrer installed on the top of the mixing tank, a packing gland installed at the interface between the stirring shaft of the stirrer and the top of the mixing tank, a liquid inlet pipe provided at the top of the mixing tank, and a liquid outlet pipe provided at the bottom;
[0005] The upper cover of the mixing tank is connected to the vacuum pump through a pipe, the outlet of the vacuum pump is connected to the exhaust gas processor, the exhaust gas processor is filled with activated carbon particles, the upper cover of the mixing tank is connected to the electric valve through a pipe, and the upper part of the electric valve is connected to the air filter through a pipe.
[0006] The outside of the packing gland is covered with a filter.
[0007] The beneficial effects of the utility model are as follows: a vacuum pump is arranged on the top of the mixing tank to suck the mixing tank into a negative pressure state, so that the gap between the stirring shaft and the packing gland is in an air intake state, which can prevent the waste gas of the methadone raw material or finished product from leaking out from this part and affecting the operators and the environment. The exhausted waste gas is discharged after being adsorbed by the activated carbon particles for harmful gases. An electric valve is arranged to open when the mixing tank is discharged to balance the air pressure in the tank. BRIEF DESCRIPTION OF THE DRAWINGS
