Detailed Description

The technical scheme of the invention is further described below with reference to the accompanying drawings and examples.

The anti-adhesion automatic material spraying device for the nickel-containing wet solid waste material brick making machine comprises a cylindrical powder bin 5, wherein the lower end of the powder bin 5 is connected with a conical discharging hopper 8, and the bottom end of the discharging hopper 8 is connected with a material spraying port 10 through a discharging pipe 9. The top end of the powder bin 5 is provided with a sealing cover 6, and a vibration baffle plate 7 is arranged in the sealing cover. The outer wall of the discharging hopper 8 is also obliquely provided with an air inlet pipe 4, and the air inlet pipe 4 is connected with an air outlet of the air compressor 3. The driving source of the vibration baffle plate 7 and the pneumatic switch 2 of the air compressor 3 are electrically connected into the control system of the center console 1.

Specifically, the discharging pipe 9 is obliquely arranged 45, and the air inlet pipe 4 is also obliquely arranged 45 degrees and downwards introduced into the outlet position of the discharging hopper 8, so that the best spraying effect is achieved, and the air inlet pipe 4 is ensured to be not easy to be blocked by powder. The material spraying opening 10 is in a flat fan-shaped structure, the fan surface forms an included angle of 25 degrees with the plane of the brick machine die 14, and the opening angle of the fan surface is 60 degrees. The air compressor 3 operates intermittently, and the exhaust pressure is controlled at 0.8MPa. The central console 1 adopts a PLC system as core control and can be connected with a brick making machine system to accurately control the material spraying time. Two powder bins 5 can be installed and mutually switched, so that maintenance without stopping production is realized, and the production efficiency is improved. The granularity of the powder is less than 5mm, the moisture is less than 3%, and the powder is convenient to discharge and spread.

Working principle: powder is put into the powder bin 5 and covered with the sealing cover 6 to prevent the powder from escaping from the top of the powder bin 5. The vibration baffle plate 7 is started and the powder is vibrated down in the discharging hopper 8. The air compressor 3 is started, high-pressure air enters the discharging hopper 8 along the air inlet pipe 4, then the powder is wrapped and clamped, passes through the discharging pipe 9, and finally is sprayed out at the position of the spraying opening 10. The diffusion area of the sprayed powder is slightly smaller than the whole plane of the die and finally falls back into the brick-shaped pit 13 under the constraint of air pressure, so that the indoor pollution caused by the powder is avoided.

The spraying time is connected with the running time of the brick making machine. The brick making machine is divided into feeding, vibration feeding, pressing, vibration compacting, demoulding and the like. The system of the center console 1 controls the first spraying to be performed before the brick making machine is fed and when no material exists in the brick type pit 13, so that the material is prevented from being adhered to the inner wall of the brick type pit 13; the second spraying is to spray powder onto the surface of the material after vibration feeding and before pressing of the brick making machine, so as to prevent the material from adhering to the brick making machine pressing head 12 on the brick making machine pressing plate 11. Each time the material is sprayed, the air compressor 3 is intermittently started for three times, and meanwhile, the vibration baffle plate 7 is also used for discharging three times, so that the powder can be ensured to uniformly cover the brick-type pit 13 or the surface of the material.

In the embodiment, the materials of the powder bin 5, the air inlet pipe 4, the discharging pipe 9, the material spraying port 10 and the sealing cover 6 are all common carbon steel materials; the diameter of the powder bin 5 is 500mm, the height is 1000mm, the diameter of the air inlet pipe 4 is DN20mm, the diameter of the discharging pipe 9 is DN35mm, the length of the fan-shaped tail end of the spraying port 10 is 200mm, and the height is 20mm. The air outlet of the air compressor 3 is connected with the air inlet pipe 4 by adopting a pressure-resistant rubber hose material, and the vibration baffle plate 7 is made of a high-strength steel plate material and a soft connecting spring. Through the device, powder and metal in the powder bin 5 are scoured and wear-resisting, and the loss is little, and on-the-spot noise is little, and the time is short, and no dust is escaped, and on-the-spot operation environment is good, and the manual work is only responsible for carrying out start-up, shut down or sudden trouble inspection.

The foregoing is a specific embodiment of the present invention, but the scope of the present invention should not be limited thereto. Any changes or substitutions that would be obvious to one skilled in the art are deemed to be within the scope of the present invention, and the scope is defined by the appended claims.
