Its core function is to realize the storage, screening, precise conveying, and stable supply of powder coatings. It is a key hub connecting powder raw materials and spraying equipment.

[0003] The existing powder supply center does not have a powder pipe backflushing system. When a major cleaning of the powder room is required, it is difficult to clean due to the large number of external pipes. Incomplete cleaning can cause color mixing, resulting in defective products. In addition, there is no dust removal system during the cleaning process, so dust overflows, increasing cleaning time and polluting the environment. Utility Model Content

[0004] The purpose of this invention is to provide a new type of powder supply center that can perform powder pipe backflushing operation, improve cleaning efficiency, and prevent color mixing.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A novel powder supply center includes a cabinet. Inside the cabinet are a fluidized powder box processing mechanism, a powder supply mechanism, and a powder pipe backflushing mechanism. The fluidized powder box processing mechanism includes a fluidized box and a fluidizing plate. The powder supply mechanism includes a powder supply pipe, a powder pump, and a powder spraying gun. The powder pump is mounted on the fluidized box, and its inlet is inserted into the fluidized box via an extension pipe. The powder supply pipe is divided into two sections: the first section connects the powder pump outlet to a tee, and the second section connects the tee to the powder spraying gun. The powder pipe backflushing mechanism includes an air tank and multiple backflushing pipes. The backflushing pipes are connected to the first and second powder supply pipes via tee pipes, and the air inlet of the backflushing pipe is connected to the air outlet of the air tank.

[0007] By adopting the above technical solution, the powder supply pipe, powder pump, and powder spraying gun can be backflushed, which can effectively improve the cleaning effect and avoid color mixing after powder replacement.

[0008] Furthermore, a pulse solenoid valve is installed at the air outlet of the backflush pipe.

[0009] By adopting the above technical solution, the pipeline of the backflush pipe can be controlled and managed.

[0010] Furthermore, a dust removal mechanism is provided on the inner side of the cabinet. The dust removal mechanism includes an air extraction device, an air extraction pipe, and a filter canister. The filter canister is installed in the pipe of the air extraction pipe. The air extraction pipe has two air inlets. The air outlet of the air extraction pipe is connected to the air inlet of the air extraction device. One air inlet of the air extraction pipe is connected to the inside of the fluidizing box, and the air inlet of the other air extraction pipe is located on the upper and lower parts of the back of the fluidizing box through a C-shaped pipe. Control valves are installed at the air inlets of both air extraction pipes.

[0011] By adopting the above technical solutions, effective dust removal operations can be carried out both inside and outside the box.

[0012] Furthermore, a pneumatic control mechanism is provided on the inner wall of the cabinet. The pneumatic control mechanism includes a pipe seat, on which a pressure regulating valve and a pressure gauge are installed.

[0013] By adopting the above technical solution, the backflush air pressure of the powder supply pipe, powder pump, and powder spraying gun can be effectively controlled.

[0014] Furthermore, an ash discharge valve is provided on the lower surface of the fluidizing box, and a cleaning port is provided on the upper surface of the fluidizing box, with a fluidizing box cover installed at the cleaning port.

[0015] By adopting the above technical solution, the interior of the fluidization tank can be cleaned conveniently.

[0016] Furthermore, an electrical control unit is installed on the inside of the cabinet.

[0017] By adopting the above technical solution, circuit control operations can be effectively performed.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] This invention allows the recovery box to be placed below the fluidizing box after use, and the discharge valve to be opened, enabling the powder inside the return box to fall effectively into the recovery box. Next, the fluidizing box cover is opened, and the dust removal mechanism is activated. The extraction device effectively removes dust from the inside of the fluidizing box, cleaning any residual powder inside. The residual powder is then removed by the extraction device. Next, the powder pipe backflush mechanism is activated, and the pulse controller periodically opens the pulse solenoid valves in sequence. The filtered compressed gas from the storage tank then enters the backflush pipe through the pulse solenoid valves. The backflush air passes through a three-way valve... The air is blown towards the powder pump and the powder spraying gun respectively. The reverse blowing of air can effectively blow out the powder from the powder pipe, the powder pump, and the powder spraying gun. Then, the above operation is repeated to clean the inside of the fluidization box. After cleaning, the fluidization box cover is closed and the discharge valve is closed. Then, the air inlet of the dust removal mechanism's exhaust pipe outside the fluidization box is opened. The dust removal mechanism is used to clean the powder in the external environment of the fluidization box. This structure can effectively clean the powder pump and powder pipes, avoid color mixing caused by incomplete cleaning, and thus avoid the occurrence of defective products. At the same time, it can conveniently clean a large number of pipes with high cleaning efficiency. Attached Figure Description

Inside the cabinet 7 are a fluidized powder box processing mechanism 1, a powder supply mechanism 2, and a powder pipe backflushing mechanism 4. The fluidized powder box processing mechanism 1 includes a fluidized box and a fluidizing plate. The powder supply mechanism 2 includes a powder supply pipe, a powder pump 8, and a powder spraying gun 11. The powder pump 8 is installed on the fluidized box, and its inlet is inserted into the fluidized box via an extension pipe. The powder supply pipe is divided into two sections: the first section connects the powder outlet of the powder pump 8 to a tee, and the second section connects the tee to the powder spraying gun 11. The powder pipe backflushing mechanism 4 includes an air storage tank 10 and multiple backflushing pipes. The backflushing pipes are connected to the first and second powder supply pipes via tee pipes. The air inlet of the blowpipe is connected to the air outlet of the air storage tank 10. A pulse solenoid valve 9 is installed at the air outlet of the backflush pipe. A dust removal mechanism 5 is installed inside the cabinet 7. The dust removal mechanism 5 includes an air extraction device, an air extraction pipe, and a filter tank. The filter tank is installed in the air extraction pipe. The air extraction pipe has two air inlets. The air outlet of the air extraction pipe is connected to the air inlet of the air extraction device. The air inlet of one air extraction pipe is connected to the inside of the fluidized bed. The air inlet of the other air extraction pipe is located at the upper and lower parts of the back of the fluidized bed through a C-shaped pipe. Control valves are installed at the air inlets of both air extraction pipes. An ash discharge valve is installed on the lower surface of the fluidized bed. An ash discharge valve is installed on the upper surface of the fluidized bed. A cleaning port is provided, and a fluidized bed cover is installed at the cleaning port. After use, the recovery box can be placed below the fluidized bed, and the discharge valve can be opened to allow the powder inside the return box to fall into the recovery box. Then, the fluidized bed cover is opened, and the dust removal mechanism 5 is activated. The air extraction device can effectively evacuate the inside of the fluidized bed, allowing the inside of the fluidized bed to be cleaned. Residual powder is removed by the air extraction device. Then, the powder pipe back-flushing mechanism 4 is activated, and the pulse controller controls the pulse solenoid valves 9 to open sequentially. At this time, the compressed gas in the filtered air storage tank 10 enters the back-flushing pipe through the pulse solenoid valves 9, back-flushing the air. The air is blown through the three-way valve to the powder pump 8 and the powder spraying gun 11 respectively. The reverse blowing air can effectively blow out the powder material inside the powder pipe, powder pump 8, and powder spraying gun 11. Then, the above operation is repeated to clean the inside of the fluidization box. After cleaning, the fluidization box cover is closed and the discharge valve is closed. Then, the air inlet of the dust removal mechanism 5 outside the fluidization box is opened. The dust removal mechanism 5 is used to clean the powder material in the external environment of the fluidization box. This structure can effectively clean the powder material remaining in the powder pump and powder pipe, avoid color mixing caused by incomplete cleaning, and thus avoid the occurrence of defective products. At the same time, it can conveniently clean a large number of pipes with high cleaning efficiency.

[0026] Reference Figure 1The inner wall of the cabinet 7 is equipped with a pneumatic control mechanism 6, which includes a pipe seat. The pipe seat is equipped with a pressure regulating valve and a pressure gauge. The inner side of the cabinet 7 is equipped with an electrical control unit 3. The pneumatic control mechanism 6 can be used to control the backflushing air pressure of the backflushing powder pipe and the powder pump, ensuring that the backflushing operation can be carried out stably. The entire automated operation can be automatically controlled by the electrical control unit 3.

[0027] Working Principle: During use, the powder pump and powder pipe on the powder supply mechanism 2 draw powder from inside the fluidization box and supply it to the nozzles to achieve stable spraying operation. After use, place the recovery box below the fluidization box, then open the discharge valve to allow the powder inside the return box to fall effectively into the recovery box. Next, open the fluidization box cover and simultaneously start the dust removal mechanism 5. The air extraction device can effectively evacuate the inside of the fluidization box, cleaning the inside of the fluidization box. Residual powder is removed by the air extraction device. Then, start the powder pipe back-flushing mechanism 4, and the pulse controller timers... The pulse solenoid valve 9 is opened in sequence. At this time, the compressed gas in the filtered air tank 10 enters the backflush pipe through the pulse solenoid valve 9. The backflush air is blown to the powder pump 8 and the powder spraying gun 11 through the three-way valve. The reverse-blown air can effectively blow out the powder inside the powder pipe, powder pump 8 and powder spraying gun 11. Then, the above operation is repeated to clean the inside of the fluidized box. After cleaning, the fluidized box cover is closed and the discharge valve is closed. Then, the air inlet of the dust removal mechanism 5 outside the fluidized box is opened, and the dust removal mechanism 5 is used to clean the powder in the external environment of the fluidized box.
