The accumulation of waste materials in a production field is avoided, the cleanliness of the production environment is kept, and meanwhile, the damage risk of normal soft capsules in the conveying process is also reduced.

The utility model relates to the technical field of medium-frequency electric furnaces, and discloses a dust collecting device for a medium-frequency electric furnace, which comprises a furnace body, a collecting box is arranged on the right side of the outer wall of the furnace body, a collecting mechanism is arranged on the outer wall of the collecting box and is used for collecting dust, and a furnace cover is arranged on the top wall of the furnace body. A fixing mechanism is arranged at the top of the furnace cover and is used for fixing a pipeline on the furnace cover; and the collecting mechanism comprises a shell, the shell is arranged on the left side of the outer wall of the collecting box, and a motor is fixedly connected to the inner bottom wall of the shell. According to the utility model, the motor drives the fan blades to rotate in the circular groove to suck dust and flue gas in the furnace body and convey the dust and flue gas to the collecting box, and meanwhile, the water pump pumps water from the water storage tank and sprays vaporific water flow through the spray head to collide with dust particles in the flue gas, so that gas-solid separation, purified gas discharge and dust deposition to the bottom of the collecting box are realized; and workers do not need to enter the dust hopper to clean accumulated dust of the guide plate.

The invention discloses a dust treatment device for antimony trioxide master batch production, and particularly relates to the technical field of dust treatment device.The dust treatment device comprises a cavity cylinder, a feeding pipe communicated with an inner cavity of the cavity cylinder is fixedly connected to the lower portion of the left side of the outer surface of the cavity cylinder, and a stirring assembly is rotationally installed on the bottom wall of the cavity cylinder; an ash storage assembly is fixedly installed in the middle of the outer surface of the cavity cylinder, and an ash storage assembly is fixedly installed on the upper portion of the inner surface of the cavity cylinder. According to the dust treatment device for antimony trioxide master batch production, the motor drives the blades to rotate, stable upward airflow is generated in the cavity cylinder, meanwhile, the transmission rod drives the stirring assembly and the beating assembly on the lower portion to rotate, the antimony trioxide master batch entering the cavity cylinder is beaten, stirred and scattered, master batch aggregates can be effectively scattered, and the production efficiency of the antimony trioxide master batch is improved. Residual dust attached to the surface and gaps of the dust collector is fully stripped and raised, then the dust is captured by ascending airflow, and the dust raising mode generated by the structure improves the removal efficiency of the residual dust.

The invention relates to the technical field of industrial catalysis, and particularly discloses a descending type catalytic reaction device with a detachable reverse shutter gas collection chamber, which comprises a continuous catalytic reaction unit and a gas-solid separation unit, the continuous catalytic reaction unit comprises a reaction cavity, the gas-solid separation unit comprises a product main channel defined by a plurality of detachable reverse shutter plates, the product main channel is communicated with a product outlet in the lower part of the reaction cavity, and a gas collection chamber is arranged outside the product main channel in a surrounding manner; the reverse shutter plate comprises a plate body, a plurality of openings and shutter blades, the openings and the shutter blades are arranged on the plate body, a gas product exhaust port is arranged on the gas collection chamber, and the gas product exhaust port is connected with a negative pressure device. The reverse shutter plates are matched with the negative pressure device, gas in the product main channel is guided to flow to the gas collection chamber, gas-solid separation is achieved, meanwhile, gas and solid are forced to flow downwards in the same direction, the catalytic reaction efficiency is improved, and the gas-solid catalytic reactor is suitable for various gas-solid catalytic reaction systems such as catalytic pyrolysis and gas-phase hydrogenation.
