Description

Technical Field

[0001] The utility model belongs to the technical field of microsilica fume drying, and particularly relates to a silica powder drying device. Background Art

[0002] Silica powder, also known as microsilica fume, needs to be dried during the processing. For example, patent application No. 202323240739.3 discloses a microsilica fume drying device, including a drying box, a drying device, a feeding device, a mixing device, etc. By setting the feeding device, since the feeding box is inclined at an angle of thirty degrees, microsilica fume enters from the feeding box, passes through a filter screen for filtration, and the filtered microsilica fume enters the drying box along the feeding box, which can filter the microsilica fume and is beneficial for subsequent drying of the microsilica fume; by setting the mixing device and the drying device, several heating tubes are turned on for heating, and at the same time, the fan is started to form hot air, which can dry the microsilica fume. The driving motor is started to drive the rotating rod to rotate, so that several stirring blades rotate, which can stir the microsilica fume. Since several stirring blades are transversely staggered, the drying of the microsilica fume is more uniform and thorough, improving the quality of microsilica fume drying.

[0003] The above-mentioned solution for drying microsilica fume has the following defects: First, in the feeding scheme, although the filter screen can block impurities in the microsilica fume, the impurities still remain in the feeding box. If it is taken out, it is necessary to use a cleaning tool to reach into the box to clean it out, resulting in a relatively inconvenient process for cleaning impurities. If it is not taken out, when the fan is running, the air flow in the drying box will blow out from the box, causing the impurities to spread to the surrounding of the equipment along with the air flow, making it even more inconvenient to clean the impurities. Secondly, the silica powder will pile up in the drying box. The silica powder at the bottom is difficult to contact the hot air, resulting in only the silica powder at the upper layer being directly affected by the hot air drying effect. Relying on the turning effect of stirring the silica powder in the disclosed technology to turn over the silica powder piled up at the bottom, although uniform drying can be achieved, the heating area of the silica powder is limited, and the time required to achieve uniform drying is relatively long. Summary of the Utility Model

[0004] In order to solve the problems existing in the prior art, the utility model provides a silica powder drying device, in which the filtered impurities can slide down by themselves, that is, there is no need to use tools to clean the impurities, and the phenomenon of impurity diffusion with the air flow will not occur. The silica powder can not only be stirred, but also increase the heating area, so as to achieve the effect of uniform drying faster.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A silicon powder drying device comprises a drying box, wherein the right side of the drying box is connected with a feed hopper, the bottom of the feed hopper is inclined downward from right to left, the top of the feed hopper is inclined upward from right to left, a filter screen is fixedly connected to the top of the feed hopper, a partition is fixedly connected inside the drying box, a fixed block is fixedly connected to the right side of the partition and the right side of the inner wall of the drying box, a guide plate is fixedly connected to the top of the fixed block, the same supporting plate is slidably sleeved on the two guide plates, a first protective net is fixedly connected to the middle of the supporting plate, a heating wire is fixedly connected inside the drying box, and the heating wire is located between the partition and the inner wall of the drying box Between the left and right sides, a fan is fixedly connected to the left side of the drying box, and the air outlet end of the fan passes through the drying box and is located on the left side of the heating wire. Two through holes are opened on the partition, one of the through holes is located above the supporting plate, and the other through hole is located below the supporting plate. A first motor is fixedly connected to the right side of the drying box, and the output shaft of the first motor passes through the drying box and is fixedly connected to a cam, and the cam is located below the supporting plate.

[0009] Furthermore, a collecting frame is fixedly connected to the right side of the drying box, the collecting frame is located below the feed hopper, and an opening is provided at the top of the collecting frame.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. Through the different inclination directions of the feed hopper and the filter, the filtered microsilica powder can enter the drying box, and the filtered impurities can slide down by themselves. Compared with the public feeding scheme, there is no need to use tools to clean the impurities, and the phenomenon of impurities diffusing with the airflow will not occur, which solves the problem of impurities needing to be cleaned during feeding.

[0012] 2. After the silicon powder falls onto the supporting plate inside the drying oven, first, through the two through-holes and the first protective net on the partition board, hot air can contact both the upper and lower sides of the silicon powder on the supporting plate, thereby increasing the heating area of the silicon powder. Secondly, in cooperation with the first motor to drive the cam, the supporting plate reciprocates upward along the guiding plate, thereby throwing up the silicon powder on the supporting plate, creating gaps between the silicon powder particles, so that the hot air flow can pass through the gaps to dry the inner area of the silicon powder, further increasing the heating area of the silicon powder. Finally, in cooperation with the second motor to drive the stirring blades to stir the thrown-up silicon powder. Compared with the disclosed technical solution, the silicon powder can not only be stirred, but also have an increased heating area, thus enabling the effect of uniform drying to be achieved faster.

[0013] 3. Through the second protective net, it can not only block the silicon powder and prevent the silicon powder from passing through the through-holes in the partition board, but also prevent the impurities in the air from being blown towards the silicon powder from the through-holes by the fan, thereby ensuring the purity of the silicon powder. When the silicon powder is fed, it is blocked by the two baffle plates to prevent the silicon powder from sliding off from the front and rear sides when it slides on the feed hopper. The collection frame facilitates the collection of the fallen impurities. Brief Description of the Drawings

The bottom of the feed hopper 2 slopes downward from right to left, and the top of the feed hopper 2 slopes upward from right to left. A filter screen 3 is fixedly connected to the top of the feed hopper 2. A partition 4 is fixedly connected inside the drying box 1. Fixed blocks 5 are fixedly connected to the right side of the partition 4 and the right side inner wall of the drying box 1. Guide plates 6 are fixedly connected to the tops of the fixed blocks 5. The same supporting plate 7 is slidably sleeved on the two guide plates 6. A first protective net 8 is fixedly connected to the middle of the supporting plate 7. A heating wire 9 is fixedly connected inside the drying box 1, and the heating wire 9 is located between the partition 4 and the left side inner wall of the drying box 1. A blower 10 is fixedly connected to the left side of the drying box 1. The air outlet end of the blower 10 penetrates into the drying box 1 and is located on the left side of the heating wire 9. Two through holes are formed in the partition 4, one through hole is located above the supporting plate 7, and the other through hole is located below the supporting plate 7. A first motor 11 is fixedly connected to the right side of the drying box 1. The output shaft of the first motor 11 penetrates into the drying box 1 and is fixedly connected to a cam 12. The cam 12 is located below the supporting plate 7. A second motor 13 is fixedly connected to the top of the drying box 1. The output shaft of the second motor 13 penetrates into the drying box 1 and is fixedly connected to a stirring blade 14. The stirring blade 14 is located above the supporting plate 7.

[0020] A second protective net 15 is fixedly connected in the through hole.

[0021] Baffles 16 are fixedly connected to the front and rear sides of the top of the feed hopper 2.

[0022] A collection box 17 is fixedly connected to the right side of the drying box 1. The collection box 17 is located below the feed hopper 2, and an opening is provided at the top of the collection box 17.

[0023] Working principle: In this utility model, microsilica powder is poured on the left side of the top of the feeding hopper 2. The silica powder slides to the right along the inclination of the top. The baffle 16 blocks the silica powder, allowing it to only slide to the right. When passing through the filter screen 3, the silica powder passes through the mesh holes of the filter screen 3 and enters the feeding hopper 2. The impurities continue to slide down along the inclined plane from the feeding hopper 2 and fall into the collection box 17. The silica powder in the feeding hopper 2 slides into the drying oven 1 along the inclined plane at the bottom and falls onto the supporting plate 7. The mesh size of the first protective net 8 is smaller than the silica powder particles, ensuring that the silica powder does not fall from the first protective net 8. Start the fan 10, heating wire 9, first motor 11 and second motor 13. The fan 10 blows air into the drying oven 1, and the heating wire 9 heats the air to form hot air. The hot air passes through the two through holes of the partition plate 4. The hot air at the upper through hole heats the upper layer of the silica powder on the supporting plate 7, and the hot air at the lower through hole passes through the mesh holes of the first protective net 8 to heat the lower layer of the silica powder. The first motor 11 drives the cam 12 to rotate. When the convex part of the cam 12 rotates upwards, it jacks up the supporting plate 7 to move upwards along the track of the guiding plate 6. When the convex part of the cam 12 faces downwards, the supporting plate 7 falls back to the fixed block 5. Thus, under the rotation of the cam 12, the supporting plate 7 reciprocates upwards to toss the silica powder. Among the tossed silica powder particles, gaps are likely to be generated, and then the hot air flow can pass through the gaps to dry the internal area of the silica powder. The second motor 13 drives the stirring blade 14 to rotate to stir the tossed silica powder. This continues until the drying work is completed. The second protective net 15 can have the same specification as the first protective net 8. After the fan 10 blows the impurities in the air into the drying oven 1, the second protective net 15 blocks the impurities from passing through the through holes. When the silica powder is tossed and stirred, the second protective net 15 also blocks the silica powder from passing through the through holes.
