Description

Technical Field

[0001] The utility model belongs to the technical field of dust prevention devices for falling fine granular materials, in particular to a dust prevention device for fine granular materials falling from high altitude. Background Art

[0002] In many industrial production industries today, such as the pharmaceutical industry, chemical industry, food processing, mineral processing, building materials industry and many other industries, a large number of fine particle products are produced during the production process.

[0003] During the transportation process, some of the materials may be thrown from high places to low places due to the height difference of the site. Also, because the fine particles themselves have low quality and are easy to disperse, a large amount of dust will be generated during the entire falling process.

[0004] Too much dust will not only waste materials, but also pollute the workers' working environment and affect their work efficiency. In serious cases, it will also harm the workers' health and industrial equipment. Therefore, dust prevention devices are usually installed to reduce the generation of dust.

[0005] At present, most of the falling dust prevention devices are too large and difficult to disassemble, and the inner wall is difficult to clean, so a large amount of dust will be attached, which not only causes the waste of granular materials but also causes secondary pollution, greatly reducing its effect. Based on this, the utility model is proposed. Utility Model Content

The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0027] Example 1: Reference Figure 1-Figure 5 A dust prevention device for fine particles falling from a high altitude comprises a silo 1, and also comprises: a transition chamber 2 in the shape of an inverted bucket is arranged above the silo 1; a plurality of telescopic tubes 3 are arranged above the transition chamber 2, and a lifting ring 4 is arranged in the middle of the outer walls on both sides of the outer side of the telescopic tube 3, and a sling 19 is arranged on the lifting ring 4; a driving part 6 is arranged at the four corners above the innermost inner wall of the telescopic tube 3, a threaded rod 10 is arranged in the telescopic tube 3, the threaded rod 10 is fixedly connected to the output end of the driving part 6, and a slider 7 is threadedly connected to the threaded rod 10; a first scraper 8 is connected to the side of the slider 7 facing the inside of the cavity, and a bracket 9 is arranged above the slider 7; a second scraper 14 is arranged on the bracket 9.

[0028] In the utility model, a lifting motor is provided at the upper end of the sling 19, and the lifting motor controls the rise and fall of the sling 19. The sling 19 is connected to the lifting ring 4, thereby controlling the telescopic length of the telescopic tube 3 to cope with scenes of different heights. The length and number of each section of the telescopic tube 3 can be customized without affecting the functional effect of the entire device. When the sling 19 is lowered to an appropriate height, the pellets are transported from above and fall into the inner opening of the telescopic tube 3. The pellets finally fall into the interior of the silo 1 through the telescopic tube 3 and the transition chamber 2. The entire process of the pellets falling is completely confined to the interior of the telescopic tube 3, the transition chamber 2 and the silo 1, thereby achieving a dust-proof effect.

[0029] The transition chamber 2 is in the shape of an inverted bucket, which makes it easier to load materials and prevents them from getting stuck.

[0030] When the whole granular material falling operation is completed, the lifting motor pulls the sling 19 up, all the telescopic tubes 3 are folded together, and the four driving parts 6 on the inside drive the threaded rod 10 to rotate. The slider 7 is provided with threads inside. When the threaded rod 10 rotates, the slider 7 reciprocates on the threaded rod 10; a bracket 9 is provided above the slider 7, and the bracket 9 extends outward and is respectively inserted into the gaps between the outer telescopic tubes 3. The bracket 9 inserted in the gaps of the telescopic tubes 3 extends to both sides, and a second scraper 14 is provided at both ends of the extension. The extension distance is that when the slider 7 stops at the driving part 6, the second scraper 14 can just touch the corner of the inner wall of the telescopic tube 3, and the distance between the two ends is symmetrical with the position of the slider 7 as the symmetry axis; when the slider 7 reciprocates on the threaded rod 10, it drives the first scraper 8 and the second scraper 14, so as to achieve the effect of cleaning the inner wall of the telescopic tube 3.

[0031] Embodiment 2: A dust prevention device for fine particles falling from high altitude is basically the same as Embodiment 1, and furthermore: an upper sealing groove 20 is provided on the inner side of the upper end of the telescopic tube 3, a lower sealing groove 21 is provided on the outer side of the lower end of the telescopic tube 3, an upper sealing ring 11 is provided below the upper sealing groove 20, and a lower sealing ring 12 is provided above the lower sealing groove 21, a bracket 15 is provided on the inner side of the lower end of the telescopic tube 3, a T-shaped groove 16 is provided on the slider 7 on the side close to the hollow pipe, the first scraper 8 is connected to the slider 7 through the T-shaped groove 16, a sliding groove 18 is provided on the upper sealing groove 20, a bottom reinforcing rib 5 is provided at the bottom of the silo 1, and a scraper strip 17 is provided on the first scraper 8 and the second scraper 14 on the side facing the inner wall of the telescopic tube 3.

[0032] In the present utility model, reference Figure 4 Except for the innermost telescopic tube 3, the upper and lower ends of the other telescopic tubes 3 are respectively provided with an inwardly protruding upper sealing groove 20 and a bracket 15, wherein an upper sealing ring 11 is provided below the upper sealing groove 20;

[0033] Except for the outermost telescopic tube 3, the lower ends of the inner telescopic tubes 3 are all provided with a lower sealing groove 21 protruding outward, and a lower sealing ring 12 is provided above the lower sealing groove 21; when the telescopic tube 3 is stretched, the upper sealing groove 20 is engaged with the lower sealing groove 21, so that the entire inner cavity is in a relatively closed space, and when the telescopic tube 3 is contracted, the bracket 15 is engaged with the inner lower sealing groove 21, thereby achieving the function of supporting the inner telescopic tube 3;

[0034] The slider 7 is provided with a T-shaped groove 16, and the first scraper 8 is hung on the slider 7 by interlocking with the T-shaped groove 16. The first scraper 8 is provided with a scraper strip 17 on the side facing the inner wall of the telescopic tube 3, and the scraper strip 17 can contact the inner wall of the telescopic tube 3. The first scraper 8 can be disassembled and replaced. The second scraper 14 is provided with a T-shaped groove 16, and the scraper strip 17 is installed on the T-shaped groove 16. The length of the front end of the scraper strip 17 can touch the inner wall of the telescopic tube 3, and the scraper strip 17 can be replaced.

[0035] The upper sealing groove 20 and the upper sealing ring 11 are both provided with a sliding groove 18, and the width of the sliding groove 18 is slightly wider than the scraper. By such a configuration, when the telescopic tube 3 slides up and down, it is prevented from interfering with the movement of the second scraper 14 and the scraper strip 17, so as not to affect the movement of the second scraper 14 and the scraper strip 17. At the same time, the second scraper 14 also plays a role in limiting the sliding of the telescopic tube 3.

[0036] A bottom reinforcement rib 5 is provided at the bottom of the silo 1 to strengthen the overall structural strength of the silo 1 , thereby preventing the silo 1 from being deformed due to the extrusion of the granular material on the silo 1 during the unloading process.

[0037] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
