Air seal type wet spraying machine discharging system and using method thereof

Abstract

The invention relates to an air seal type wet spraying machine discharging system and a using method thereof. The air seal type wet spraying machine discharging system comprises a discharging hopper, a distributor, a discharging pipe, a material receiving plate and a high-pressure air pipe, wherein the upper end face of the distributor communicates with the discharging hopper, the lower end face of the distributor communicates with the material receiving plate, the discharging hopper, the distributor and the material receiving plate are coaxially distributed, the front end face of the material receiving plate communicates with the discharging pipe through a flow guide opening, the rear end face of the flow guide opening communicates with the high-pressure air pipe, the discharging hopper is of a groove-shaped structure with the axial section being in an inverted isosceles trapezoid shape, the material receiving plate is of a closed cavity structure with the axis section being in a rectangular shape, the upper end face of the material receiving plate is provided with the flow guide opening and communicates with the distributor, and the using method of the discharging system comprises two steps of equipment assembling and material distributing and conveying. According to the air seal type wet spraying machine discharging system and the using method thereof, on one hand, materials in a powdery state, a liquid state, a solid-liquid mixed state and the like can be effectively and continuously distributed and conveyed, on the other hand, the defect that when a traditional wet spraying machine operates, due to the fact that the pressure of the discharging position is too large, the materials in a charging barrel flow back, and material supply and feeding stability is poor is effectively overcome.

Description

technical field [0001] The invention relates to a blanking system of an air-sealed wet spraying machine and a method for using the same, belonging to the technical field of spraying equipment. Background technique [0002] During the blanking, distributing and grouting operations of the wet spraying machine, since all kinds of distributing equipment currently used are often the traditional material barrel and metal distributing plate structure, although it can meet the needs of the distributing operation, but in the distributing During the material operation process, the current feeding pressure of the material inlet of the distributor is often lower than that of the outlet, so it is very easy to cause the air pressure at the outlet to be too high during the material distribution operation of the distributor. On the one hand, As a result, the material from the outlet of the distributor cannot be effectively transported to the spraying system of the wet spraying machine; The...

[0002] During the blanking, distributing and grouting operations of the wet spraying machine, since all kinds of distributing equipment currently used are often the traditional material barrel and metal distributing plate structure, although it can meet the needs of the distributing operation, but in the distributing During the material operation process, the current feeding pressure of the material inlet of the distributor is often lower than that of the outlet, so it is very easy to cause the air pressure at the outlet to be too high during the material distribution operation of the distributor. On the one hand, As a result, the material from the outlet of the distributor cannot be effectively transported to the spray system of the wet spray machine; The discharge port of the feeder flows back into the feeder, which causes serious material distribution and feeding failures in the feeder. At the same time, it also causes a large amount of wear of the feeder equipment during operation. In severe cases, it even causes the feeder to block and fail. Cause serious equipment damage, affecting the stability of normal spraying and feeding operations and the stability and reliability of equipment operation
