Description

Technical Field

[0001] The utility model relates to the field of conveying and mixing materials, in particular to a vacuum conveying and mixing device. Background Art

[0002] During the production process, materials need to be transported between different equipment. Solid materials are often transported by mechanical equipment such as belt conveyors, bucket elevators, and screw conveyors. However, these cannot meet the requirements of material transportation for conveying volume and distance. In addition, the main pipeline and the closed-loop circulation pipeline are connected in a tangential manner, and the material conveying direction is one-way circulation. The conveying efficiency is low and it is not suitable for solid materials that are easy to precipitate.

[0003] Chinese patent CN202321576186.6 provides a vacuum liquid-solid conveying device, which diverts liquid and solid materials through an annular distributor, shortens the path of liquid and solid materials entering each branch pipeline, effectively reduces the sedimentation rate of solid materials, increases the conveying amount of solid-containing materials, and prevents the erosion and corrosion of equipment and pipelines by solid-containing materials during the conveying process. It is particularly suitable for conveying solid materials that are easy to precipitate. However, when conveying mixed powder materials, it is not convenient to stir and mix the powder materials, because the powder materials may agglomerate due to friction and static electricity due to high-speed movement, making the powder mixing not uniform. If they are not crushed and stirred, it may affect the use of the powder materials.

[0004] Therefore, it is necessary to provide a vacuum conveying and mixing device to solve the above technical problems. Utility Model Content

[0013] 1. A vacuum conveying and mixing device, which intermittently hollows out the interior of a silo through a vacuum pump, and the silo draws powder materials in the silo through a conveying pipe, so that the powder materials in the silo enter the silo. Because the powder materials are affected by the suction force, the powder materials are in an eruptive state when entering the silo. Therefore, the powder materials impact the stirring blades, and the powder materials are scattered by the reaction force.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 4 , a vacuum conveying and mixing device provided by an embodiment of the utility model comprises a silo 1, a mixing silo 2 and a conveying pipe 3, wherein the mixing silo 2 is installed on the right side of the silo 1, the left end of the conveying pipe 3 is installed on the bottom end of the silo 1, and the right end of the conveying pipe 3 is installed on the left end of the mixing silo 2; the mixing silo 2 comprises a silo barrel 202, the interior of the silo barrel 202 is rotatably connected with an axle rod 204, the outer end of the axle rod 204 is fixedly connected with a plurality of stirring blades 206 arranged equidistantly, the stirring blades 206 are adapted to the conveying pipe 3, a vacuum pump 203 is installed on the right end of the silo barrel 202, the input end of the vacuum pump 203 is communicated with the silo barrel 202, a dust cover is installed on the input end of the vacuum pump 203 and located inside the silo barrel 202, and the silo barrel 202 is adapted to the stirring blades 206;

[0022] The conveying pipe 3 is used to facilitate the mixing bin 2 to suck the powder material from the silo 1. At the same time, the mixing operation of the powder material can be completed synchronously to prevent the powder from agglomerating and affecting the subsequent use. The vacuum pump 203 intermittently hollows the interior of the silo 202, and the silo 202 extracts the powder material in the silo 1 through the conveying pipe 3. As a result, the powder material in the silo 1 enters the silo 202. Since the powder material is affected by the suction force, the powder material is in an eruptive state when entering the silo 202. Therefore, the powder material impacts the stirring blade 206, and the powder material is scattered by the reaction force. At the same time, the stirring blade 206 is impacted and rotated by the shaft 204, and the stirring blade 206 changes its position and angle. Therefore, when the powder material is introduced again subsequently, the powder has a different dispersion angle, and the powder introduced for the second time is mixed with the powder introduced for the previous time. At the same time, the stirring blade 206 can stir the powder at the bottom of the silo 202 when it rotates, so that the powder introduced for the second time is mixed with the powder introduced for the previous time more evenly.

[0023] The silo 1 includes a silo body 101 , and a bracket 102 is fixedly connected to the outer end of the silo body 101 .

[0024] The outer end of the silo 202 is fixedly connected to a support frame 201 .

[0025] The bottom end of the silo 202 is fixedly connected to a discharge hopper 207, the bottom end of the discharge hopper 207 is fixedly connected to a discharge pipe 208, and the bottom end of the discharge pipe 208 is installed with a discharge solenoid valve 209;

[0026] The discharge pipe 208 is opened and closed by the discharge solenoid valve 209 , and the discharge pipe 208 is convenient for discharging the materials in the discharge hopper 207 , and the discharge hopper 207 is convenient for discharging the mixed materials in the silo 202 .

[0027] The top end of the shaft rod 204 penetrates the top end of the silo 202 , and a connecting block 205 is fixedly connected to the top end of the shaft rod 204 and located at the top end of the silo 202 , and the connecting block 205 is rotatably connected to the silo 202 .

[0028] The conveying pipe 3 includes a discharge pipe 301 and a feed solenoid valve 302. The discharge pipe 301 is installed at the bottom end of the silo body 101, and the feed solenoid valve 302 is installed at the left end of the silo barrel 202. The feed solenoid valve 302 penetrates the left end of the silo barrel 202 and is adapted to the stirring blade 206. The right end of the discharge pipe 301 is fixedly connected with a delivery pipe 303, and the delivery pipe 303 is communicated with the feed solenoid valve 302.

[0029] The opening and closing of the discharge pipe 301 is controlled by the feed solenoid valve 302 to prevent the residual powder in the discharge pipe 301 from entering the vacuum pump 203 when the vacuum pump 203 is running and affecting the suction of the material in the bin body 101.

[0030] During operation, the discharge solenoid valve 209 and the feed solenoid valve 302 are closed, and the vacuum pump 203 is turned on. The vacuum pump 203 intermittently evacuates the interior of the silo 202. After the silo 202 is evacuated, the feed solenoid valve 302 is turned on, and the silo 202 extracts the powder material in the silo body 101 through the discharge pipe 301. As a result, the powder material in the silo body 101 enters the silo 202. Since the powder material is affected by the suction force, the powder material is in an eruptive shape when entering the silo 202. Therefore, the powder material impacts the stirring blade 206, and the powder material is scattered by the reaction force. At the same time, the stirring blade 206 is impacted and By rotating the shaft 204, the stirring blade 206 changes its position and angle. Therefore, when the powder material is introduced again subsequently, the powder has a different dispersion angle, and the powder introduced for the second time is mixed with the powder introduced last time. At the same time, the stirring blade 206 can stir the powder at the bottom of the silo 202 when it rotates, so that the powder introduced for the second time is mixed more evenly with the powder introduced last time. After the mixing is completed, the discharge solenoid valve 209 is opened. At this time, the discharge hopper 207 discharges the mixed material in the silo 202 into the discharge pipe 208. The discharge pipe 208 can be connected to an external receiving container so that the mixed powder material can be collected.
