Specific embodiments

[0021] The present utility model will be further described below in conjunction with specific embodiments. However, those skilled in the art should understand that the detailed description given here in conjunction with the drawings is for better explanation. The structure of the present utility model necessarily goes beyond these limited embodiments, and for some equivalent replacement schemes or common means, no detailed description will be given herein, but they still fall within the protection scope of the present application.

[0022] Figures 1 to 4 is the best embodiment of the present utility model. The following combines the attached Figures 1 to 4 to further describe the present utility model.

[0023] A vacuum pumping buffer device for milk powder, comprising a buffer mechanism 1 and a vacuum pump 2. The buffer mechanism 1 is connected to the intake end of the vacuum pump 2. The buffer mechanism 1 includes a buffer box 101 and a separation box 102. The separation box 102 is fixedly installed on the top of the buffer box 101. A filter plate 3 is rotatably installed on the top of the buffer box 101. The filter plate 3 is located between the buffer box 101 and the separation box 102. A rotating mechanism 4 is arranged inside the separation box 102, and the rotating mechanism 4 is connected to the filter plate 3 to drive its rotation. A partition channel 5 is fixedly installed inside the separation box 102. One end of the partition channel 5 is located above the filter plate 3 and is in contact with it, covering half of the filter plate 3. The other end of the partition channel 5 is located outside the separation box 102. A flow limiting mechanism 6 is arranged on the surface of the separation box 102, and the flow limiting mechanism 6 is in contact with the other end of the partition channel 5. Specifically, the buffer mechanism 1 filters the air flow entering the vacuum pump 2 to prevent part of the powder from entering the interior of the vacuum pump 2 along with the air flow during the vacuum pumping process of milk powder canning, which affects the normal operation of the vacuum pump 2. The air flow entering the buffer box 101 is filtered by the filter plate 3, and the filtered gas is transported to the vacuum pump 2 by the separation box 102. The rotating mechanism 4 drives the filter plate 3 to rotate between the buffer box 101 and the separation box 102, so that the covered part of the filter plate 3 located below the partition channel 5 is continuously replaced, and the powder adhered to the bottom of the filter plate 3 is blown off by the air flow at the partition channel 5. The flow limiting mechanism 6 freely regulates the opening of the intake end of the partition channel 5 to prevent the excessive flow gap from affecting the vacuum pumping efficiency.

[0024] The buffer mechanism 1 further includes an intake pipe 103, an air delivery pipe 104 and a material storage box 105. The intake pipe 103 is fixedly installed on the front side of the buffer box 101. The air delivery pipe 104 is fixedly installed on the top of the separation box 102, and the free end of the air delivery pipe 104 is connected to the vacuum pump 2. A cover plate is hingedly installed on the front side of the buffer box 101. A material storage box 105 is placed inside the buffer box 101. Specifically, the gas is transported through the intake pipe 103 and the air delivery pipe 104, and the filtered milk powder is temporarily stored in the material storage box 105.

[0025] The rotating mechanism 4 includes a support plate 401, a motor 402, a rotating shaft 403 and a transmission wheel 404. The support plate 401 is fixedly installed inside the separation box 102. The motor 402 is fixedly installed on the top of the support plate 401. The rotating shaft 403 is rotatably installed on the surface of the support plate 401, and the bottom end of the rotating shaft 403 is connected to the top of the filter plate 3. The rotating shaft 403 and the filter plate 3 are on the same axis. The number of transmission wheels 404 is two groups. One group of transmission wheels 404 is fixedly installed at the output end of the motor 402, and the other group of transmission wheels 404 is fixedly installed at the top end of the rotating shaft 403. The two groups of transmission wheels 404 are meshed and connected. Specifically, the motor 402 drives the transmission wheel 404 to rotate. Through the conduction of the two groups of transmission wheels 404, the rotating shaft 403 drives the filter plate 3 to rotate.

[0026] The separation channel 5 includes a separation cover 501, a ventilation pipe 502 and a filter cartridge 503. The ventilation pipe 502 is fixedly installed on the surface of the separation box 102. One end of the ventilation pipe 502 is inside the separation box 102 and is fixedly connected to the separation cover 501. The other end of the ventilation pipe 502 is outside the separation box 102 and is fixedly connected to the filter cartridge 503. Specifically, the filter cartridge 503 filters the gas entering the ventilation pipe 502 from the outside to prevent pollution inside the buffer mechanism 1. The gas is blown to the top of the filter plate 3 through the ventilation pipe 502 and the filter cartridge 503 to assist in cleaning the powder material.

[0027] The separation cover 501 is semicircularly arranged. The bottom of the separation cover 501 is attached to the top of the filter plate 3. A detachable and replaceable filter element is provided inside the filter cartridge 503. Specifically, by covering one side of the top of the filter plate 3 with the separation cover 501, during the vacuum pumping operation, the air flow flows along the part not covered by the separation cover 501. Rotating the filter plate 3 makes the part with adhered powder material switch to below the separation cover 501, causing the powder material at that place to fall off.

[0028] The flow limiting mechanism 6 includes a U-shaped plate 601, a through groove 602, a flow limiting plate 603 and a screw 604. The U-shaped plate 601 is fixedly installed outside the separation box 102. A through groove 602 is opened on one side of the U-shaped plate 601. A flow limiting plate 603 is slidably installed on one side of the U-shaped plate 601, and a gap corresponding to the through groove 602 is opened on the surface of the flow limiting plate 603. A screw 604 is rotatably installed on the top of the U-shaped plate 601, and the screw 604 is threadedly connected to the top of the flow limiting plate 603. Specifically, by rotating the screw 604, the flow limiting plate 603 is driven to slide along one side of the U-shaped plate 601. Controlling the staggered position of the gap of the screw 604 and the through groove 602 adjusts the size of the gap for the flowing air.

[0029] In summary: when the utility model is in use, the staff drives the vacuum pump 2 to perform the vacuum operation of the milk powder can. A small amount of powder is carried in the pumped airflow, and the gas enters the buffer box 101, is blocked and filtered by the filter plate 3, and the powder falls and is temporarily stored in the storage box 105. Part of the powder adheres to the bottom of the filter plate 3, which fails to prevent the equipment from running for a long time. Too much powder adhered to the filter plate 3 affects the gas circulation efficiency. The rotating mechanism 4 and the flow limiting mechanism 6 are driven regularly to clean the powder at the filter plate 3, and the flow limiting plate 603 is moved to drive the flow limiting plate 603 to slide along the front side of the U-shaped plate 601. The filter plate 3 is rotated by the rotating shaft 403, and the bottom side where the powder adheres is rotated to the bottom of the separation cover 501. As the vacuum is drawn, the external air flows through the limiting plate 603 and the through groove 602, is filtered and decontaminated by the filter cartridge 503, and then is blown to the top of the filter plate 3 through the vent pipe 502 and the separation cover 501, thereby blowing the powder at the bottom of the filter plate 3 off to prevent the powder from clogging the filter plate 3 and affecting the vacuum drawing of the milk powder can.
