[0024] Please refer to Figure 1-3 The utility model provides a technical scheme:

[0025] A vacuum feeding and feeding equipment.

[0026] The hopper 110 is provided with a vacuum feeding assembly for vacuum feeding the hopper 110, a filtering assembly installed in the hopper 110 for filtering the material, a back flushing assembly installed on the top of the hopper 110 for cleaning the filtering assembly, a discharge assembly installed in the hopper 110 for preventing incomplete discharge of the material, a discharge valve 140 installed at the bottom of the hopper 110, a suction pipe 120 installed on the sidewall of the hopper 110, a feeding valve 130 installed on the suction pipe, and a static electricity elimination assembly installed on the hopper 110 for reducing static electricity of the hopper 110.

[0027] The hopper 110 serves as a temporary storage and transfer container for the material. The vacuum feeding assembly uses the negative pressure generated by the vacuum pump 310 to suck the material into the hopper 110. The filtering assembly separates the material from the air. The back flushing assembly cleans the filtering assembly to prevent the filter screen from being blocked and prolong its service life. The discharge assembly ensures that the material can be completely discharged from the hopper 110 by stirring and cleaning the inner wall, avoiding residue. The discharge valve 140 controls the discharge of the material, and the suction pipe 120 and the feeding valve 130 control the suction of the material. The design of the entire device aims to improve the efficiency and reliability of material conveying while reducing manual operation and material waste.

[0028] The discharge assembly includes a stirring rod 210, a driving mechanism, and an inner wall cleaning mechanism. One end of the stirring rod 210 is rotatably connected to the inner wall of the hopper 110 through a sealing bearing. A plurality of sets of stirring blades 220 are installed on the stirring rod 210, and each set of stirring blades 220 is arranged equidistantly in a ring shape around the stirring rod 210. The driving mechanism is installed on the hopper 110 and is in transmission connection with one end of the stirring rod 210. The inner wall cleaning mechanism is arranged in the hopper 110 and is installed on the stirring rod 210.

[0029] The discharge assembly works cooperatively with the stirring rod 210, the driving mechanism, and the inner wall cleaning mechanism to ensure that the material can be completely discharged from the hopper 110. The stirring rod 210 is rotatably connected to the inner wall of the hopper 110 through a sealing bearing, and the stirring blades 220 on it can stir the material to prevent clumping or accumulation. The driving mechanism provides power to rotate the stirring rod 210, and the inner wall cleaning mechanism cleans the residual material by the scraper 250 adhering to the inner wall of the hopper 110. This design not only improves the efficiency of discharging, but also reduces the residue of the material in the hopper 110, improving the utilization rate of the equipment.

[0030] The driving mechanism includes a motor 230 installed on the top of the hopper 110, and the output end of the motor 230 is in transmission connection with one end of the stirring rod 210.

[0031] Motor 230 provides driving force, and the rotation of the output shaft of motor 230 drives the stirring rod 210 to rotate, thereby causing the stirring blades 220 to stir the material. This design ensures the stability and continuity of the stirring process, and the power of motor 230 can be selected according to the properties of the material and the requirements to achieve the best stirring effect.

[0032] The inner wall cleaning mechanism includes a scraper 250 and a connecting rod 240. One end of the connecting rod 240 is mounted on the stirring rod 210, and the scraper 250 is mounted on the other end of the connecting rod 240, and the scraper 250 is attached to the inner wall of the hopper 110.

[0033] The internal wall cleaning mechanism, through the design of scraper 250 and connecting rod 240, achieves cleaning of the inner wall of hopper 110. Connecting rod 240 is mounted on stirring rod 210, and scraper 250 is mounted on the other end of connecting rod 240, ensuring that scraper 250 can move in contact with the inner wall of hopper 110 as stirring rod 210 rotates. This design not only removes residual material from the inner wall but also prevents scaling, improving the cleanliness and service life of the equipment.

[0034] The vacuum feeding assembly includes a vacuum pump 310, which is installed on the outer wall of the hopper 110. One end of the vacuum pump 310 is equipped with an air extraction pipe 320, and one end of the air extraction pipe 320 is connected to the top of the hopper 110. A first solenoid valve 330 is installed on the air extraction pipe 320.

[0035] The vacuum feeding assembly generates negative pressure through a vacuum pump 310, drawing material from the suction pipe 120 into the hopper 110. The vacuum pump 310 is mounted on the outer wall of the hopper 110, and the suction pipe 320 is connected to the top of the hopper 110. The suction process is controlled by a first solenoid valve 330. This design allows material to be quickly and efficiently drawn into the hopper 110 under negative pressure. Simultaneously, the use of the first solenoid valve 330 precisely controls the suction time and pressure, ensuring the stability and reliability of the feeding process.

[0036] The filter assembly includes a baffle plate 340, which is installed inside the hopper 110. The baffle plate 340 is rotatably connected to the stirring rod 210 via a sealed bearing, and multiple filter elements 350 are installed on the baffle plate 340.

[0037] The filter assembly filters the material entering the hopper 110 through the design of the baffle 340 and filter element 350. The baffle 340 is installed inside the hopper 110 and is rotatably connected to the stirring rod 210 via a sealed bearing, ensuring that the baffle 340 is not damaged during stirring, and that material does not pass through the connection between the stirring rod 210 and the baffle 340. The filter element 350 is installed on the baffle 340 and is used to separate the material from the air.

[0038] The back flushing assembly comprises an air inlet pipe 410, one end of the air inlet pipe 410 is connected to the top of the hopper 110, and a second electromagnetic valve 420 is installed on the air inlet pipe 410.

[0039] The back flushing assembly blows gas into the hopper 110 through the air inlet pipe 410 for cleaning the filter assembly. The air inlet pipe 410 is connected to the top of the hopper 110, and the second electromagnetic valve 420 controls the entry of the gas, so that the gas can enter the hopper 110 to clean the filter element 350 and clean the material on the filter element 350, avoiding the material adhering to the filter element 350. This design enables the filter assembly to remove the blocked material by reverse blowing, restores the filtering effect, prolongs the service life of the filter assembly, and reduces the downtime and maintenance cost of the equipment.

[0040] The static electricity elimination assembly comprises a static electricity eliminator 510, which is installed on the side wall of the hopper 110.

[0041] The static electricity elimination assembly eliminates static electricity on the hopper 110 by the static electricity eliminator. The static electricity eliminator 510 is installed on the side wall of the hopper 110 to reduce static electricity on the hopper 110, thereby preventing static electricity from accumulating on the hopper 110 and avoiding that the accumulation of static electricity may cause a serious explosion accident during the conveying of flammable and explosive dust.

[0042] Specifically, the internal electrical connection structure, specific structure and model of the feed valve 130, the discharge valve 140, the motor 230, the vacuum pump 310, the first electromagnetic valve 330, the second electromagnetic valve 420 and the static electricity eliminator 510 are well known to those skilled in the art, and will not be described here.
