Description

Technical Field

[0001] The utility model relates to the technical field of construction waste treatment equipment, in particular to a sealed unloading device for a construction waste impurity removal system. Background Art

[0002] In the decoration waste disposal process, light material impurities and dust in fine aggregates are attracted by a negative pressure pipeline above an impurity removal and separation machine, fall into a negative pressure cyclone cylinder and settle in a discharge valve. As Figure 5 shown is a discharge valve in the prior art. A valve plate IIb is installed at the lower end of a valve core housing IIa. The valve plate IIb is movably connected to the lower end of the valve core housing IIa through a valve plate shaft IId. The opening and closing of the discharge port at the lower end of the valve core housing IIa relative to the valve plate IIb is driven by a driving device, so as to realize the opening and closing of the discharge valve core. The valve core housing IIa is installed inside a discharge box 1. The driving device includes a cylinder IIc installed on the discharge box 1. The output shaft of the cylinder IIc is fixedly connected to one end of a shaft seat. The shaft seat is fixedly connected to the valve plate circumference IId. The counterclockwise and clockwise rotation of the shaft seat is driven by the extension and contraction of the output shaft of the cylinder IIc, so as to drive the opening and closing of the valve plate IIb relative to the material discharge port of the valve core housing IIa. However, the valve of the discharge valve in the foregoing prior art is not tightly sealed. During the spiral settlement process of light material impurities and dust, some lighter light material impurities will float up again after descending, and normal discharging cannot be achieved. Moreover, it will cause blockage of the cyclone cylinder and the subsequent dust removal system, and even the blades of the screw conveyor in the dust collector will fall off and the main shaft will break, seriously affecting the normal production of the system. In addition, the valve plate driving structure of the existing discharge valve directly drives the opening and closing of the valve plate through the valve plate shaft IId. Only one side of the valve plate IIb is subjected to the rotational force to control its opening or closing, and the design is unreasonable. The valve plate IIb is frequently deformed and the connection between the valve plate shaft IId and the valve plate IIb is broken. Summary of the Utility Model

[0028] In this embodiment, rubber plates 25 are installed on the edges of the material discharge opening at the lower end of the valve core housing I21. The lower ends of the rubber plates 25 are ground flat. When the valve plate I22 closes the material discharge opening, the sealing performance between the valve plate I22 and the valve core housing I21 can be ensured, preventing light material impurities and dust from floating up again during the sedimentation process, so that the light material impurities and dust can fully settle, avoiding blockage and damage to the cyclone and the subsequent dust removal system, reducing the maintenance cost of the cyclone and the dust removal system, and reducing the workload of the staff for unclogging, thereby improving production efficiency.

[0029] In this embodiment, compared with the prior art method of directly driving the opening and closing of the valve plate by driving the valve plate shaft IId to rotate through a driving device, the valve plate I22 is movably connected to one side of the material discharge opening of the valve core housing I, and a valve plate driving device is separately provided. When opening or closing the valve plate I22, the rear part of the valve plate I22 is driven by the valve plate driving device to open or close relative to the material discharge opening, so that the force application point and the force receiving point are respectively located on the discharge box 1 and the rear opening of the valve plate I22.
