Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment. It should be understood that "upper", "lower", "left", "right", "front" and "back" mentioned in the following embodiments of the present invention are all based on the directions shown in the respective drawings, and these words for limiting the directions are only for convenience of explanation and do not represent limitations on specific technical aspects of the present invention.

The environment-friendly dust removing equipment provided by the invention replaces the original hand-pulled gate valve by sequentially arranging the single-layer flap valve, the flat valve and the sealing box body at the lower end of the ash collecting cone, improves the direct open-type discharge of the original hand-pulled gate valve into closed-type discharge, and avoids secondary pollution to the environment.

As shown in fig. 2 (the arrow in the figure represents the air inlet direction of the air inlet pipe), the environment-friendly dust removing device has the following specific structure: the ash collecting device comprises an ash collecting cone body 21 which is vertically arranged, an air inlet pipe 22 which is connected with the ash collecting cone body 21, and a single-layer flap valve 23, a flat valve 24 and a sealing box body 25 which are sequentially arranged at an ash outlet at the lower end of the ash collecting cone body 21. The inner diameters of the single-layer flap valve 23 and the flat valve 24 are consistent with the inner diameter of the ash outlet of the ash collecting cone 21, the single-layer flap valve 23 controls ash discharge at the ash discharging position of the ash collecting cone 21 through gravity, and the flat valve 24 controls ash discharge at the ash discharging pipeline through an air cylinder; the dust collected in the dust collection cone 21 enters the sealed box 25 through the control of the single-layer flap valve 23 and the flat valve 24 for dust collection.

Wherein, the individual layer flap valve 23 plays the ash discharge and sealed effect, utilizes the dead weight of material (the dust of collecting) to carry out automatic dust discharging device, and when material weight reached 8 jin, one-way opening, then reset and close when being less than this weight, this flashboard can be reliable resets. The single-layer flap valve 23 is formed by welding high-quality steel, and has the advantages of simple structure, free operation, flexible sliding of the valve plate, excellent sealing performance, small local resistance loss, good adjusting performance, convenient maintenance and disassembly and difficult deformation. A flange with the thickness of 10mm is welded on a dust outlet at the lower end of the dust collecting cone 21 and is connected with the single-layer flap valve 23 through screws and nuts, the lower end of the single-layer flap valve 23 is connected with the flat valve 24 through a pair of flanges, the valve is vertically installed, a sealing gasket is required to be sealed between the two flanges during installation, and then connecting bolts are uniformly locked.

The flat valve 24 controls the ash discharging pipeline to discharge ash into the sealed box 25 through the air cylinder 26, one end of the air cylinder 26 is connected with the compressed air pipe, the compressed air pressure is 0.4-0.7Pa, and a sealing gasket must be sealed between the two flanges during installation. The flat valve is installed horizontally, and the flat valve 24 includes: the device comprises an actuating mechanism, a valve body, an inserting plate, a sealing device and a travel switch. The flat valve 24 is set to open once within 10 minutes for ash discharge, namely, a time relay sends an instruction to a pneumatic control system of the flat valve, an air source of the pneumatic control system outputs an instruction to an actuating mechanism, the actuating mechanism drives the inserting plate to be pushed outwards, the flat valve is opened, otherwise, the inserting plate valve is closed, and the inserting plate of the flat valve is pushed inwards. The plate valve 24 is of a fully-closed structure, has good protection performance and can meet all-weather requirements, and the pressure of an inner cavity can be automatically released when the plate valve is closed, so that the use safety is ensured.
