Description

Powder centralized receiving device

technical field

The invention belongs to the field of operation technology, and relates to a collection device, in particular to a powder centralized collection device.

Background technique

In daily production, some products are in powder form, such as lithium iron phosphate, iron oxide, titanium dioxide and so on.

In order to collect products during production, a powder recovery device is required. Documents about powder recovery devices such as the suspension kiln broken powder recovery device disclosed in Chinese patent literature [application number: 201020295746.7; announcement number: CN201776058U], cyclone dust collector, bag filter, and the air outlet of the cyclone dust collector are connected by pipelines The air inlet of the bag dust collector. Although this recovery device can collect powder; but there are still some defects: when the above recovery device is used to collect powder, the cyclone dust collector captures large particle powder, and the small particle powder enters the bag filter with the air, and then is collected Bag dust collector capture; that is, the particle size of the powder collected by the cyclone dust collector is obviously larger than that of the bag dust collector. However, some products (such as lithium iron phosphate powder) need to mix large particles and small particles together in actual use; obviously, the products collected by the above-mentioned recovery device need to be stirred and mixed again, so there are more processes and equipment investment. , Operators increased, production costs increased and so on.

The purpose of the present invention can be achieved through the following technical solutions: a concentrated powder collection device, characterized in that it includes a cyclone collection device, the cyclone collection device has a cylinder, a cone, connected to the inner cavity of the cylinder A feed pipe connected to the feed pipe, a discharge pipe connected to the small port of the cone, and an exhaust pipe located in the cylinder body, one end of the exhaust pipe passes through the top surface of the cylinder body; The tube is divided into a bag-type receiver with a filter outer cavity and a filter inner cavity; the filter outer cavity communicates with the cylinder inner cavity.

Use this powder collecting device to collect powder, the feeding pipe is connected with the powder discharge pipe, the exhaust pipe is connected with the fan, the discharge pipe is connected with the receiving bin, and the discharge pipe is connected in series A valve that connects or shuts off the discharge pipe. When the fan is running, the airflow will change from linear motion to circular motion when the powder and air enter the cyclone receiver from the tangential feed pipe. Most of the swirling air flow spirals downward from the cylinder to the cone along the wall of the device. The gas containing powder produces centrifugal force during the rotation process, and the powder with a relative density higher than that of the gas is thrown to the wall of the container. Once the powder is in contact with the wall, it loses the radial inertial force and falls along the wall by the downward momentum and gravity, and enters the ash discharge pipe. When the rotating and descending outer swirling gas reaches the cone, it moves closer to the center of the cyclone receiver due to the constriction of the cone. According to the principle of constant "rotational moment", its tangential velocity increases continuously, and the centrifugal force on the powder also increases continuously. When the airflow reaches a certain position at the lower end of the cone, it starts from the middle of the cyclone receiver in the same direction of rotation, reverses from bottom to top, and continues to do spiral flow, that is, internal swirling airflow. The last part of the powder that is not trapped also enters the outer cavity of the exhaust pipe to filter.

The powder that has not been captured is collected by the bag collector again, and the cleaner gas enters the filter cavity of the exhaust pipe, and is discharged out of the pipe through the exhaust pipe. The powder collected by the bag-type receiver naturally falls into the ash discharge pipe through the ash cleaning device; thus, both the large particle powder and the micro particle powder enter the ash discharge pipe, that is, the collected powder large particles Mixed with tiny particles.
