Description

A jet pulverization system with a trapping device

Technical field:

The utility model relates to the field of crushing equipment, in particular to an airflow crushing system with a trapping device.

Background technique:

The jet mill is an important equipment for ultrafine powder processing. Since the jet mill needs compressed air as the air source, the production process consumes a lot of energy. Under the premise of ensuring the particle size of the product, improving the crushing efficiency as much as possible and reducing the unit energy consumption is the direction of the research and development of the jet mill. The current types of jet mills mainly include disc jet mills, fluidized bed jet mills, circulating tube jet mills and rake jet mills, among which the most commonly used are disc jet mills and flow mills. Bed type jet mill. The disc type airflow mill has the advantage of high crushing efficiency, but the particle size classification accuracy is low; while the fluidized bed airflow mill has high classification accuracy, but the crushing efficiency is low and the price is high. Large, so it occupies a large area and is inconvenient to install and maintain.

Utility model content:

The technical problem to be solved by the utility model is to provide an airflow pulverization system with a trapping device, which is convenient to operate and install, and has high pulverization efficiency and particle size classification precision.

The technical problem to be solved by the utility model adopts the following technical solutions to realize:

An airflow pulverization system with a collecting device, comprising a disc type airflow pulverizer, a cyclone separator, a pulse dust collector, an induced draft fan and a pipeline, the top of the disc type airflow pulverizer is provided with an exhaust port, and the bottom is provided with a There is a discharge port, and the outside is provided with a feeder, a crushing nozzle, and an air distribution pipe connected to the feeder and the crushing nozzle. The cyclone separator is connected to the exhaust port of the disc-type jet mill through a pipeline, and the top of the cyclone separator passes through The pipeline is connected to the pulse dust collector, and the top of the pulse dust collector is connected to the induced draft fan through the pipeline. The lower end of the cyclone separator and the pulse dust collector is equipped with an air hammer, and the bottom is equipped with a star discharge valve.

An air volume valve is provided between the induced draft fan and the pulse dust collector.

An elastic hose is provided between the exhaust port and the pipeline, between the air volume valve and the pipeline, and an elastic hoop is provided outside the elastic hose.

Working principle of the utility model:

The air distribution pipe sends the compressed air into the crushing chamber and the feeder inside the disc-type jet mill respectively. The materials in the feeder are mixed with the compressed air and then enter the crushing chamber after being pressurized. The fully crushed materials move in the form of laminar flow. For classification, the particles equal to the size of the classification are discharged from the discharge port, the particles larger than the size of the classification return to the crushing area and continue to be crushed, and the particles smaller than the size of the classification enter the pipeline through the exhaust port with the airflow, and then enter the cyclone separator for further crushing. The particles are pre-collected, and then enter the pulse dust collector for gas-solid separation. The captured particles are discharged by the star discharge valve after being struck by an air hammer, and the exhaust gas is evacuated by the induced draft fan.

The beneficial effects of the utility model are: simple structure, reasonable design, convenient operation, the crushing efficiency and particle size classification accuracy can be improved through the disc type jet mill, and the cyclone separator and pulse dust collector can effectively capture the dust generated by crushing , thereby reducing the material loss rate and protecting the environment.
