For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Figure 1 This is a front view of the dust-free feeding device in the utility model; Figure 2 It is a side view of the dust-free feeding device in the utility model; Figure 3 yes Figure 1 AA section view. Figures 1 to 3 As shown, a preferred embodiment is shown, which shows a dust-free feeding device, including a barrel 1, a cleaning door 2, a filter bag 3, a back-blowing spray system 4, a suction device 5 and a grid support frame 6. The upper end of the barrel 1 is provided with a back-blowing spray system 4, a cleaning door 2 is provided on one side of the barrel 1, and the inside of the barrel 1 is provided with a filter bag 3 and a grid support frame 6. The grid support frame 6 is located at the lower side of the filter bag 3, and the lower end of the barrel 1 is provided with a suction device 5. In this embodiment, see Figure 1 and Figure 2 As shown, the grid support frame 6 is made of stainless steel, and one end of the cleaning door 2 is hinged to the barrel body 1. By opening the cleaning door 2, raw materials can be fed into the barrel body 1, and by opening the cleaning door 2, the inside of the barrel body 1 can be easily cleaned or repaired.

[0023] A high-pressure fan 7 is provided at the upper end of the barrel body 1, and the high-pressure fan 7 is connected to the upper end of the barrel body 1. Suction can be generated by the high-pressure fan 7, so that the dust raised in the raw material can be adsorbed on the filter bag 3 to prevent the dust from being blown into the air.

[0024] When in use, open the cleaning door 2, then place the packaging bag containing the raw materials on the grid support frame 6, then cut the packaging bag of the raw materials with a blade, then close the cleaning door 2, and start the suction device 5 and the high-pressure fan 7. At this time, the raw materials fall to the bottom of the barrel 1 after passing through the grid support frame 6, and the suction device 5 transports the raw materials to the designated position. At the same time, the raised dust can be adsorbed on the filter bag 3 under the action of the high-pressure fan 7, which can prevent the dust from entering the outside air. After the raw materials are transported, start the back-blowing spray washing system 4, pump high-pressure air into the inside of the filter bag 3, and clean the dust attached to the filter bag 3. Through the setting of the filter bag 3, the raw materials can be prevented from being sucked away by the high-pressure fan 7, and the flying powder will be adsorbed on the filter bag 3 to prevent air pollution caused by dust leakage. The back-blowing spray washing system 4 can clean the dust adhering to the filter bag 3, reduce the frequency of manual disassembly and cleaning of the filter bag 3, and greatly improve the use time of the bag.

[0025] The grid support frame 6 and the material suction device 5 in this embodiment are both existing structures and are not limited here.

[0026] Further, as a preferred embodiment, a plurality of filter bags 3 are provided, and a mounting seat for mounting the filter bags 3 is provided inside the barrel body 1. There is a certain gap between the mounting seat and the upper inner wall of the barrel body 1, and a chamber can be formed between the mounting seat and the upper inner wall of the barrel body 1. When the high-pressure fan 7 is working, negative pressure can be generated in the chamber, so that dust can adhere to the filter bags 3.

[0027] Among them, the mounting seat is provided with a mounting hole, and the outer edge of the opening of the filter bag 3 is mounted on the inner wall of the mounting hole. In other embodiments, a mounting hole can be opened at the upper end of the barrel body 1, and the outer edge of the upper opening of the filter bag 3 can be set on the inner wall of the mounting hole, and a negative pressure box can be provided at the upper end of the barrel body 1, the negative pressure box is connected to the mounting hole, the high-pressure fan 7 is connected to the negative pressure box, and the air inlet pipe 402 in the back-blowing spray system 4 passes through the negative pressure box and extends into the filter bag 3. The high-pressure fan 7 and the air storage tank 401 can both be set on the negative pressure box.

[0028] Further, as a preferred implementation, the backwashing system 4 includes an air tank 401, an air inlet pipe 402 and a control valve 403. The air tank 401 is arranged at the upper end of the barrel 1. The air tank 401 is connected to the filter bag 3 through the air inlet pipe 402. The control valve 403 is arranged on the air inlet pipe 402. The air inlet pipe 402 can directly extend into the filter bag 3 or into the chamber. When the control valve 403 is opened, the high-pressure gas in the air tank 401 can enter the filter bag 3 through the air inlet pipe 402 to flush the filter bag 3, so that the dust on the filter bag 3 is blown off. The control valve 403 can be a solenoid valve or a manual mechanical valve, which can be selected according to needs.

[0029] Further, as a preferred embodiment, a handle 8 is provided on the cleaning door 2. The handle 8 is provided to facilitate opening or closing the cleaning door 2.

[0030] Further, as a preferred embodiment, it also includes a support frame 9, and the barrel body 1 is installed on the support frame 9. The support frame 9 is used to install the barrel body 1, and a support plate is provided at the lower end of the support frame 9 to increase the contact area with the ground.

[0031] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
