[0002] Vacuum feeders are devices that use negative pressure to transport materials, including granules and powders. They are now widely used in various light and heavy industries such as chemical, pharmaceutical, food, metallurgy, building materials, and agricultural products.
[0003] Vacuum feeders use negative pressure and conveying pipes to transport materials from the raw material area, such as a silo, to the target equipment. If the material being transported is a mixture, during the transport process, differences in density, weight, and shape can cause the material to stratify inside the vacuum feeder, failing to meet the requirements of the production process.

[0027] This utility model provides a vacuum feeder with stirring function, such as... Figure 1-4 The system includes: a silo body 1, a negative pressure pipe 2, a stirring device 3, a dust removal device 4, and a backflushing device 5. The upper part of the silo body 1 is a feeding silo 11, and the lower part is a stirring silo 12. A feeding port 111 is opened on the wall of the feeding silo 11. The feeding port 111 is connected to the material in the raw material area at the front end through a conveying pipe. One end of the negative pressure pipe 2 is connected to the upper part of the feeding silo 11, and the other end of the negative pressure pipe 2 is connected to a fan. A distribution valve 21 is installed on the negative pressure pipe 2. The negative pressure pipe 2 draws in the gas in the feeding silo 11, so that a negative pressure is formed in the feeding silo 11. Then, the negative pressure feeding silo 11 absorbs the material through the feeding port 111. The material drawn into the feeding silo 11 falls into the stirring silo 12. The stirring device 3 is installed on the stirring silo 12. The stirring device 3 mixes and stirs the material in the stirring silo 12. A discharge pipe 121 is set at the bottom of the stirring silo 12.
[0028] like Figure 3-5 The stirring device 3 includes a stirring motor 31, a reducer 32, a stirring shaft 33, and a stirring paddle 34.

The conical part of the mixing chamber 12 is inclined, and the agitator 34 rotates in close contact with the conical part of the mixing chamber 12. The agitator 34 has a large rotating working area and a large surface area. The agitator 34 rotates in close contact with the inner wall of the mixing chamber 12, avoiding material adhesion and bridging on the inner wall of the mixing chamber 12. The angle between the agitator shaft 33 and the horizontal plane is 4°. At 5°, when the stirring paddle 34 rotates and stirs, it mixes and stirs the material in both the horizontal and vertical directions, avoiding the stratification of the material in the mixing chamber 12. The stirring device 3 also includes a dispersant 35, which is located on the inner side of the end of the blade of the stirring paddle 34. The dispersant 35 is "C" shaped, and both ends of the "C" shaped dispersant 35 are fixed on the stirring paddle 34. During the rotation and stirring process of the stirring paddle 34, the dispersant 35 can better disperse and mix the materials, thereby improving the stirring efficiency and effect.
[0030] like Figure 1 , Figure 3 A discharge valve 122 is installed on the discharge pipe 121, and the discharge valve 122 controls the opening and closing of the discharge pipe 121.

A high level gauge 112 is installed on the feeding chamber 11, and the detection part of the high level gauge 112 enters the mixing chamber 12 through the feeding chamber 11. The height of the detection part of the high level gauge 112 is higher than the height of the detection part of the low level gauge 123.
[0032] like Figure 1 , 3 A feed valve 113 is installed at the feed inlet 111, and the feed valve 113 controls the opening and closing of the feed inlet 111.
[0033] An air venting valve 114 is installed on the feed hopper 11.
[0034] like Figure 1 , Figure 4 The dust removal device 4 is installed in the feed hopper 11, above the feed inlet 111. The dust removal device 4 includes a mounting plate 41 and dust collection bags 42. The mounting plate 41 is fixedly installed inside the feed hopper 11, dividing the feed hopper 11 into upper and lower halves. The upper and lower halves of the feed hopper 11 are detachably installed. The mounting plate 41 has several through holes for installing the dust collection bags 42. When installing the dust collection bags 42, if... Figure 4 With the opening of the dust collector bag 42 facing upwards, the body of the dust collector bag 42 is passed downwards through the through hole of the mounting plate 41, so that the body of the dust collector bag 42 is located in the lower half of the feed hopper 11, and the opening of the dust collector bag 42 is fixed on the mounting plate 41.
[0035] like Figure 1-4 , Figure 6 The backflush device 5 is installed on the outer wall of the feed hopper 11.

[0036] During operation, the blower is turned on, the venting valve 114 is closed, the feed valve 113 controls the opening of the feed inlet 111, and the distribution valve 21 controls the opening of the negative pressure pipe 2. The blower draws air through the negative pressure pipe 2 to create negative pressure in the feed hopper 11. The material from the raw material area enters the hopper 1 through the conveying pipe and the feed inlet 111, falling into the mixing hopper 12. Some material is carried upwards by the airflow and dispersed, and the dust collection bag 42 filters out the dispersed material. When the high-level gauge 112 detects that the material has reached the high level, the venting valve 114 is opened, the blower is turned off, the distribution valve 21 controls the closing of the negative pressure pipe 2, and the feed valve 113 controls the closing of the feed inlet 111. The pulse valve 53 of the back-flushing device 5... The system operates by controlling the backflush pipe 54 to blow out pulsed gas, which cleans the material on the dust collector bag 42. The material on the dust collector bag 42 falls into the mixing chamber 12. After cleaning, the pulse valve 53 closes. The mixing motor 31 drives the mixing paddle 34 to rotate through the reducer 32 and the mixing shaft 33. The mixing paddle 34 thoroughly mixes the material in the mixing chamber 12. After mixing, the discharge valve 122 controls the discharge pipe 121 to open, and the material in the mixing chamber 12 is transported to downstream equipment through the discharge pipe 121. When the low level gauge 123 detects that the material is at a low level, the discharge ends after a delay, and the discharge valve 122 controls the discharge pipe 121 to close.
