A flap door structure

Abstract

The invention relates to the technical field of material blanking isolation and specifically discloses a turnover panel door structure. The turnover panel door structure is good in sealing performance and can effectively guarantee the isolation effect. A housing is provided with an opening, the opening is internally provided with a square step, a door plate capable of overturning is arranged at a position, which is close to the lower end surface of the square step, on the inner wall of the housing through a rotating shaft, the two ends of the rotating shaft penetrate the housing and are connected with a bearing pedestal, one end of the rotating shaft is also connected with a driving motor, the bearing pedestal and the driving motor are both installed outside the housing, the other end of the rotating shaft is connected with a counterweight block through a counterweight arm, the dimension of the door plate is greater than the dimension of the opening, the lower end surface of the square step is provided with a square seal washer corresponding to the door plate, a row of perforations are arranged in the inner wall of the housing opposite to the rotating shaft, the perforations are internally provided with guide sleeves, a row of driving cylinders are installed outside the housing where the guide sleeves are disposed, piston rods of the driving cylinders are provided with guide rods penetrating the guide sleeves, and when the door plate is closed, the guide rods extend outwards to be disposed at the lower end of the door plate and are in contact with the lower end surface of the door plate.

Description

technical field [0001] The invention relates to the technical field of material blanking partition, in particular to a flap door structure. Background technique [0002] In some places such as pipelines where materials are discharged, flap doors are generally installed to realize partitioning, and the passage and blocking of materials are realized by opening and closing the flap doors. The existing flap doors have simple structures and poor sealing performance. When there are many materials and liquid, the seal may not be tight, and the partition effect is poor. Contents of the invention [0003] In order to solve the above problems, the present invention provides a flap door structure, which has good sealing performance and can effectively ensure the partition effect. [0004] Its technical solution is as follows: a flap door structure, which includes a housing, characterized in that an opening is opened on the housing, a square step is arranged in the opening, and the i...
