When the inner wall paint powder adding device is used, the connecting pipe 30 is communicated with an air source, and the air source is a device for generating compressed air, such as an air compressor; the electromagnetic valve 31 is opened, compressed air enters the inner cavity of the transverse pipe 20 through the connecting pipe 30 and the taper pipe 40, powder filled in the hopper falls into the inner cavity of the transverse pipe 20 through the first through hole 21, and the inner diameter of the transverse pipe 20 is smaller (10-20cm) under the gravity extrusion of the powder even if a large amount of powder is filled in the hopper due to the fact that the transverse pipe 20 is horizontally arranged, and if the compressed air is not adopted to impact the powder in the transverse pipe 20, the powder in the transverse pipe 20 can be blocked; under the impact of compressed air, the powder inside the horizontal pipe 20 falls into the reaction kettle through the elbow joint 50 and the film pipe 60; wherein, the film tube 60 is arranged inside the reaction kettle, the film tube 60 can be made of polypropylene material with the thickness of less than 2mm, and is soft, easy to bend and easy to bend; the counterweight ring 61 can be a lead ring, and the thin film tube 60 is of a vertical tube structure under the action of the counterweight ring 61; in the process, because the transverse pipe 20 is horizontally arranged, an excessively high height difference is not needed between the hopper and the reaction kettle, and the installation limitation is small; even if the humidity of the external environment is high, the compressed air is adopted for impact; the interior of the cross tube 20, elbow 50 and membrane tube 60 are not susceptible to clogging. The electromagnetic valve 31 can intermittently work in the ways of starting for 3 seconds, stopping for 1-2 seconds, starting for 3 seconds and stopping for 1-2 seconds …, the electromagnetic valve 31 intermittently works, compressed air is saved, the intermittent impact effect is better than the continuous impact effect, and powder is easy to disperse even if being blocked; and the continuous flushing of the compressed air reduces the efficiency with which the powder inside the hopper falls inside the transverse tube 20.

The ratio of the inner diameter of the connecting pipe 30 to the inner diameter of the transverse pipe 20 is x, and x is more than or equal to 0.16 and less than or equal to 0.28. This allows a sufficient concentration of the compressed air inside the connecting tube 30 while ensuring a sufficient flow rate.

Further, the connecting pipe 30 includes a vertical pipe section and a horizontal pipe section perpendicular to the vertical pipe section, the horizontal pipe section is connected with the small end of the taper pipe 40, and the solenoid valve 31 is installed in the vertical pipe section. Even if powder exists at the horizontal section, the powder cannot flow upwards to the electromagnetic valve 31, and therefore the electromagnetic valve 31 is prevented from being blocked.

Further, as shown in fig. 1 and 3, a driving mechanism 80 for driving the elbow joint 50 to rotate is disposed above the elbow joint 50, the driving mechanism 80 includes a vertical cylinder 81, a bottom plate 82 fixedly disposed at a lower end of the vertical cylinder 81, an iron plate 83 disposed inside the vertical cylinder 81, and an electromagnet 84 disposed at an upper end of the vertical cylinder 81, a cord 85 is disposed between the iron plate 83 and the counterweight ring 61, a second through hole 821 for the cord 85 to move is disposed at a center of the bottom plate 82, a tail end of the cord 85 is fixedly connected to an outer side wall of the counterweight ring 61, a head end of the cord 85 passes through the second through hole 821, a head end of the cord 85 is fixedly connected to a middle portion of the iron plate 83, and the electromagnet 84 is fixedly connected to an upper end of. Wherein, clearance fit is adopted between the iron plate 83 and the inner cavity of the vertical cylinder 81.

When feeding needs to be suspended in the feeding process, at the moment, the electromagnet 84 is electrified, the electromagnet 84 generates magnetic force to attract the iron plate 83 to move upwards, the head end of the rope 85 can be pulled to move upwards in the upward movement process of the iron plate 83, meanwhile, the tail end of the rope 85 can pull the counterweight ring 61, the counterweight ring 61 can drive the film pipe 60 to enable the elbow joint 50 to rotate along the central axis direction of the transverse pipe 20, finally, the head end of the film pipe 60 and the counterweight ring 61 are in the obliquely upward positions, the head end of the film pipe 60 and the height of the counterweight ring 61 are both higher than the height of the transverse pipe 20, at the moment, the compressed air is stopped to be blown into the transverse pipe 20, and the head end of the film pipe 60 is both higher than the height of the transverse pipe 20, so that powder cannot flow out at the head end of the film; the effect of closing the valve is achieved.

That is, the elbow joint 50, the film pipe 60 and the driving mechanism 80 are used in a matched manner, so that the feeding stopping action can be completed in time, a gate valve is not required to be installed, and the operation is simple and convenient; the elbow joint 50 and the film pipe 60 can be arranged outside the reaction kettle, even if dust overflows from the film pipe 60, the dust only overflows into the reaction kettle, and the workshop environment and the use are not influenced.
