Description

Pneumatic plate turnover fan for rice processing

Technical Field

The utility model relates to a mechanical equipment technical field, more specifically say, it relates to a pneumatic board-turning over closes fan for rice processing.

Background

The air-lock valve is used in a pneumatic conveying pipeline, also called an air-lock valve, materials fall into the pneumatic conveying pipeline below through a shell of the air-lock valve, and the materials are conveyed by a centrifugal fan or other pneumatic forces.

For example, as shown in fig. 1, although the pneumatic flap air-lock (application number: CN201822065561.6) for rice processing disclosed in the chinese patent document solves the problem of achieving that a certain amount of rice bran can enter into a feed hopper and finally into an air-lock body, on one hand, the bagging amount of rice bran can be controlled, on the other hand, bagging is more convenient and fast, and no dust is generated, and work efficiency is improved, in the operation of the device, "rice bran at an upper rice bran discharge port falls into an inlet, and then falls onto a flap, at this time, a user turns on a power supply of the air-lock body, and at the same time, the user controls the operation of the air cylinder, a telescopic rod of the air cylinder moves upward and drives a fixed block to synchronously move upward, and the fixed block drives a connecting plate to move upward, one end of the connecting plate rotates along a pin shaft in a strip-shaped groove, the horizontal distance of connecting plate and fixed block changes and grow gradually, the one end of connecting plate drives fixed block and cylinder skew right this moment, the bottom of cylinder rotates around the free bearing, when the one end of connecting plate sticks up the time-out, the other end of connecting plate drives the pivot and rotates, turn over with pivot fixed connection's board simultaneously and turn over, turn over the rice bran on the board and fall into in the feeder hopper, and fall into the feed inlet of closing the fan body through the connecting pipe afterwards, final rice bran is from the discharge gate department output of closing the fan body, the user of service bagging-off can.

During operation, although the problem that 'a certain amount of rice bran can enter the feeding hopper and finally enter the air-lock body' is solved, the specific capacity of the certain amount of rice bran entering the feeding hopper cannot be accurately controlled, meanwhile, when the air-lock body works, the operation of a manual control cylinder is basically the same as the labor amount of manual control of the capacity of the rice bran through the inserting plate, so that the labor intensity of users is high, the rice bran capacity on the turning plate in the feeding hopper cannot be observed by the users, the rice bran capacity on the turning plate cannot be accurately controlled by the users, and the motor of the air-lock body is easy to generate larger vibration when working, because the air-lock body is connected with the feeding hopper in the prior art, the vibration generated by the motor of the air-lock body is easy to be transmitted to the hinge base on the surface of the feeding hopper, so that the normal use of the air cylinder and the turning plate connected on the hinge base, the turnover plate in a turnover state is easy to shake, so that rice bran on the turnover plate cannot fall into the feed hopper completely.
