Technical Field

[0001] The utility model belongs to the field of powder feeding equipment, and particularly relates to a dual-powder metering and feeding device. Background Art

[0002] In the food and pharmaceutical industries, powder mixing is a very important production task. During the production process of products, it is often necessary to put two or more kinds of powders into a mixer for mixing. To control the product quality, the materials need to be accurately put in according to a certain proportion. Therefore, powder feeding equipment using a metering disk for metering and feeding has been widely used. It has accurate metering accuracy and excellent dust-proof performance, and is very suitable for powder feeding. However, currently, the relevant equipment generally can only feed a single kind of powder. In the case of needing to feed multiple kinds of powders, it can only be solved by increasing the number of equipment. After the number of equipment increases, a large number of supporting equipment also need to be arranged. When the number of feeding types is small, a large number of equipment will be idle, which will undoubtedly increase the production cost of the enterprise and occupy a large amount of production space.

[0019] For the convenience of understanding by those skilled in the art, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] As shown Figure 1 in the figure, a dual-powder metering and feeding device includes a storage cylinder 100 for storing powder. An observation window 101 is provided on the wall of the storage cylinder 100, through which the internal state of the storage cylinder 100 can be observed. A cylinder cover 110 is provided above the storage cylinder 100, and the cylinder cover 110 is used to close the storage cylinder 100 to prevent powder from generating dust. A partition 120 for dividing the space inside the cylinder into two cavities is provided inside the storage cylinder 100, and the two cavities can store two different kinds of powder. Two feeding ports corresponding to the two cavities are provided on the cover plate 130, and the feeding ports can be connected to an external pneumatic conveying device for feeding the powder into the storage cylinder 100. The bottom end of the partition 120 is connected to a cover plate 130, a metering plate 140 is provided below the cover plate 130, a bottom plate 170 is provided below the metering plate 140, and the bottom plate 170 is used to prevent all the powder in the metering holes 144 from falling. A feeding hopper 180 is connected below the bottom plate 170, and the feeding hopper 180 is used to collect materials and feed them into an external mixing device.

[0021] The metering plate 140 is connected to a rotary drive mechanism 150, and the rotary drive mechanism 150 is a reduction rotary motor, which is provided above the cylinder cover 110. This embodiment also includes a through pipe 151 vertically arranged inside the cylinder. The through pipe 151 penetrates through the partition 120 and the cover plate 130, and the output shaft 152 of the reduction rotary motor penetrates through the through pipe 151 and is connected to the metering plate 140. The through pipe 151 can isolate the output shaft 152 of the rotary reduction motor from the powder inside the storage cylinder 100 to prevent the operation of the equipment from being affected. Two inner and outer circles of openings 141 are provided on the metering plate 140, and two annular grooves corresponding to the two circles of openings 141 are provided at the bottom of the metering plate 140. Ring members 142 are provided in both annular grooves, and sleeves 143 matching the openings 141 are provided at the tops of the two ring members 142, and metering holes 144 are provided inside the sleeves 143.

[0022] The two ring members 142 and the metering plate 140 cooperate to form two circles of metering holes 144. The ring members 142 are replaceable parts, and the metering value of the metering plate 140 is adjusted by replacing the ring members 142 with different inner diameters of the metering holes 144. In actual feeding work, the feeding ratios of materials for different products need to be adjusted. A metering plate with fixed metering hole diameters controls the feeding amount by adjusting the rotation speed. In this embodiment, the metering plate 140 is provided with two circles of metering holes 144. When the diameters of the two circles of metering holes 144 are both fixed, adjusting the rotation speed of the metering plate 140 will cause the feeding amounts of the two materials to change together. By setting replaceable ring members 142 in this embodiment, the diameters of the two circles of metering holes 144 can be adjusted, and the feeding ratios of the two materials can be flexibly adjusted.

[0023] The cover plate 130, the metering disc 140 and the bottom plate 170 cooperate to control the feeding amount of the powder material. Two circles of metering holes 144 are provided on the metering disc 140. Two openings 131 for feeding the two circles of metering holes 144 are provided on the cover plate 130. The two openings 131 are respectively located on both sides of the partition plate 120. The two kinds of powder materials in the storage cylinder 100 enter the inner circle of metering holes 144 and the outer circle of metering holes 144 through the two openings 131 respectively, preventing the materials from mixing. Two discharge holes 171 corresponding to the two circles of metering holes 144 are formed on the bottom plate 170. Both of the two discharge holes 171 are under the coverage of the cover plate 130.

[0024] When the rotation drive mechanism 150 drives the metering disc 140 to rotate, the powder material in the storage cylinder 100 will enter the metering holes 144 through the openings 131 on the cover plate 130. After the metering holes 144 are filled with the powder material, they rotate to the lower part of the cover plate 130. The edges of the openings 131 on the cover plate 130 will scrape off the powder material on the surface of the metering disc 140, preventing the excess powder material from entering the cover plate 130 and ensuring that the powder material amount in the metering holes 144 is consistent. When the metering holes 144 filled with the powder material rotate to the position of the discharge holes, the powder material can fall through the powder holes to achieve feeding. An air blowing mechanism is provided at the bottom of the cover plate 130. The air blowing mechanism includes two air blowing ports 160. The two air blowing ports 160 respectively correspond to the two discharge holes 171. To prevent the powder material from sticking in the metering holes 144, when the metering holes 144 rotate to the discharge holes, the air blowing ports 160 can blow off the powder material. The air blowing mechanism further includes two air channels 161 and two air pipe connectors 162. The two air channels 161 are both formed inside the cover plate 130 and are respectively connected to the two air blowing ports 160. The two air pipe connectors 162 are provided on the side of the cover plate 130. The two air pipe connectors 162 are respectively connected to the two air channels 161. The two air pipe connectors 162 can be connected to an external air supply device, and the gas is transported through the air pipes to the air blowing ports 160 and blown out.

[0025] Working process: The two kinds of powder materials respectively enter the two cavities in the storage cylinder 100 through the two feeding ports on the cylinder cover 110. During feeding, the rotation drive mechanism 150 drives the metering disc 140 to rotate. The two kinds of powder materials in the storage cylinder 100 are isolated by the partition plate 120 and enter the outer circle of metering holes 144 and the inner circle of metering holes 144 through the two openings 131 on the cover plate 130 respectively. When the filled metering holes 144 rotate to the corresponding positions of the discharge holes 171, the air blowing mechanism will blow off the powder material, so that the two kinds of powder materials fall into the hopper 180 to achieve the metering feeding of the two kinds of powder materials.

[0026] The above embodiments are the preferred implementation manners of the present invention and are not intended to limit the present invention. Without departing from the inventive concept of the present invention, any obvious replacement is within the protection scope of the present invention.
