A dust-proof device for a silo according to an embodiment of the present invention will be described with reference to fig. 1 to 4.

As shown in fig. 1 to 4, the dustproof device for a storage bin according to an embodiment of the present invention includes:

the telescopic feeding pipe 100 is vertically arranged in the storage bin 600, and the top end of the feeding pipe 100 is connected with a feeding hole 601 of the storage bin 600;

the screen 200 is horizontally arranged in the feeding pipe 100, and the screen 200 is connected with a first vibrator 201;

the dust collector is communicated with the feeding pipe 100;

the driving mechanism 400 is disposed on the bin 600, and is used for controlling the feeding pipe 100 to extend and retract.

In this embodiment, when the bulk material needs to be loaded into the bin 600, the driving mechanism 400 is activated, and the driving mechanism 400 controls the feeding pipe 100 to extend and retract, specifically, when the bulk material is not stored in the bin 600, the bottom end of the feeding pipe 100 is close to the bottom of the bin 600, and when a part of the bulk material is stored in the bin 600, the bottom end of the feeding pipe 100 is close to the top of the bulk material in the bin 600. Then, the vacuum cleaner and the first vibrator 201 are started, and the bulk material is poured into the feeding pipe 100 from the feeding hole 601 of the bin 600, so that the bulk material can enter the bin 600 from the bottom end of the feeding pipe 100. According to the dustproof device for the storage bin, disclosed by the embodiment of the utility model, as the bottom end of the feeding pipe 100 can be close to the bottom in the storage bin 600 or the top end of the bulk materials in the storage bin 600, and then the bulk materials fall into the storage bin 600 from the feeding hole 601, the dust in the bulk materials is always positioned in the feeding pipe 100, and then the dust in the feeding pipe 100 can be sucked into the dust collector without being diffused into the storage bin 600, so that a large amount of dust can be effectively prevented from being generated in the storage bin 600. In addition, the screen 200 and the first vibrator 201 are arranged, the first vibrator 201 drives the screen 200 to vibrate, the bulk materials firstly fall onto the screen 200, then pass through the through holes in the screen 200 under the vibration of the screen 200 and finally pass through the feeding pipe 100 to enter the bin 600, the screen 200 plays roles of speed reduction and vibration, dust on the bulk materials can be sufficiently separated from the bulk materials, and further, the situation that part of the dust is separated from the bulk materials and is diffused into the bin 600 after the bulk materials pass through the feeding pipe 100 and enter the bin 600 along with the bulk materials can be avoided, so that a large amount of dust can be further prevented from being generated in the bin 600.

It should be noted that, first, one side of the silo 600 may be provided with a bucket elevator 700, the bucket elevator 700 may lift the bulk materials to the top of the silo 600, the bucket elevator 700 may be provided with a discharge pipe 701, and the discharge pipe 701 may be communicated with the feed port 601 or directly extend into the interior of the feed pipe 100. Secondly, during the process of loading the bulk materials, the bulk materials in the bin 600 will gradually increase, and further the height of the bulk materials in the bin 600 will gradually increase, so the driving mechanism 400 needs to control the extension and retraction of the feeding pipe 100, so that the bottom end of the feeding pipe 100 is always located at a set distance above the bulk materials in the bin 600, and the position can not only enable the bulk materials to conveniently enter the bin 600 from the feeding pipe 100, but also prevent the situation that a large amount of dust is diffused because the bottom end of the feeding pipe 100 is too high. In addition, in the present invention, the screen 200 does not perform a filtering function, that is, the aperture of the through hole on the screen 200 is larger than the size of the bulk material, the screen 200 only reduces the dropping speed of the bulk material, and simultaneously, the dust and the bulk material can be sufficiently separated by self-vibration, the first vibrator 201 controls the vibration of the screen 200, the first vibrator 201 may be a common vibrator, and the structure and the operation principle thereof are not described herein again. The suction cleaner communicates with the feed pipe 100, i.e. the suction cleaner is provided with a suction pipe 300, the suction pipe 300 communicating with the feed pipe 100.

In some embodiments of the present invention, as shown in fig. 2 to 4, the dust-proof device for a storage bin further includes a mounting frame 500, the mounting frame 500 is provided with a bearing portion 501, the bearing portion 501 is carried at the top end of the storage bin 600, the mounting frame 500 passes through the feed port 601 and extends into the feed pipe 100, and the screen 200 is disposed on the mounting frame 500. Bearing part 501 can set up on the top of mounting bracket 500, and mounting bracket 500 bears on the top of feed bin 600 through bearing part 501, and that is to say mounting bracket 500 can be taken out from the top of inlet pipe 100, and then the top of inlet pipe 100 can be taken out to screen cloth 200, compares in the direct rigid coupling of screen cloth 200 in inlet pipe 100, when needing to wash, change or maintain screen cloth 200, and the dismouting is more convenient and laborsaving.

In some embodiments of the present invention, as shown in fig. 3 and 4, the mounting frame 500 is provided with a plurality of bosses 502 along the circumference of the feeding pipe 100, the bosses 502 are vertically provided with springs 503, and the screen 200 is connected to one end of the springs 503 far away from the bosses 502. Compared with the screen 200 directly fixedly connected to the mounting frame 500, the spring 503 is arranged between the screen 200 and the mounting frame 500, so that the vibration amplitude of the screen 200 can be increased, the dust and bulk materials can be better separated, the rigid impact force between the screen 200 and the mounting frame 500 can be reduced, the damage probability of the screen 200 and the mounting frame 500 can be reduced, and the service lives of the screen 200 and the mounting frame 500 are longer. The spring 503 may be provided at the top end of the boss 502, and the screen 200 may be provided at the top end of the spring 503, and the spring 503 may be provided at the bottom end of the boss 502, and the screen 200 may be provided at the bottom end of the spring 503.

In some embodiments of the present invention, as shown in fig. 4, a sleeve 504 is vertically disposed on the boss 502, and the sleeve 504 is sleeved on one end of the spring 503. The sleeve 504 prevents the spring 503 from bending and deflecting in the radial direction when compressed, so that the compression effect of the spring 503 is better. The sleeve 504 is only sleeved on one end of the spring 503, so that interference on the expansion and contraction of the spring 503 can be avoided.

In some embodiments of the present invention, as shown in fig. 2 and 3, a plurality of speed reducers 505 are attached to the mounting frame 500 below the screen 200, and the speed reducers 505 are inclined downward in a direction away from the connection position of the speed reducers 505 with the mounting frame 500. After passing through the through holes of the screen 200, the bulk material first falls onto the speed reduction plate 505, then slides to the bottom end of the speed reduction plate 505 in the inclined direction of the speed reduction plate 505, and then falls off from the bottom end of the speed reduction plate 505. The speed reduction plate 505 is arranged, so that the falling speed of the bulk materials can be further reduced, and meanwhile, the bulk materials can slightly shake when falling onto the speed reduction plate 505, so that dust and the bulk materials can be more sufficiently separated, and the dust removal effect is better.

In some embodiments of the present invention, as shown in fig. 2 and 3, two speed reduction plates 505 are arranged above and below each other, and the connection positions of the two speed reduction plates 505 and the mounting frame 500 are located at two sides of the feeding pipe 100 in the axial direction. Further, after the bulk materials fall onto the first speed reduction plate 505 and are separated from the first speed reduction plate 505, the bulk materials are also easily fallen onto the second speed reduction plate 505, so that the speed reduction effect when the bulk materials fall is better, and the dust and the bulk materials can be more sufficiently separated. It should be noted that, in order to enable the bulk material on the first speed reduction plate 505 to drop onto the second speed reduction plate 505, the end of the second speed reduction plate 505 away from the self-connection position may be located directly below the first speed reduction plate 505, and of course, even if the end of the second speed reduction plate 505 away from the self-connection position is not located directly below the first speed reduction plate 505, most of the bulk material can still drop onto the second speed reduction plate 505 under the inertia effect. In this embodiment, the number of the speed reduction plates 505 may be one or three or more according to actual requirements.

In some embodiments of the present invention, as shown in fig. 3 and 4, the upper end of the screen mesh 200 is provided with a plurality of spikes 202, and the pointed ends of the spikes 202 face upward. The spine 202 is provided to separate the partially bonded bulk materials, so that the bulk materials can pass through the through holes of the screen 200 and the dust and the bulk materials can be more sufficiently separated.

In some embodiments of the present invention, as shown in fig. 2 and 3, the feeding pipe 100 includes a connection pipe 101 connected to the feeding port 601 and a bellows 102 connected to a bottom end of the connection pipe 101, the vacuum cleaner is connected to the connection pipe 101, the driving mechanism 400 includes a plurality of winding machines 401 disposed at a top end of the storage bin 600, the winding machines 401 are wound with a pulling rope 402, and a bottom end of the pulling rope 402 is connected to a bottom end of the bellows 102. The winch 401 is started, and the winch 401 can control the lifting of the bottom end of the corrugated pipe 102 through the traction rope 402, so that the feeding pipe 100 can stretch. The connection pipe 101 is not telescopic, and the dust collector is communicated with the connection pipe 101 instead of the corrugated pipe 102, so that the connection effect and the sealing effect between the dust collector and the feeding pipe 100 are not influenced. The hoisting machines 401 can be two and are arranged on two opposite sides of the feeding pipe 100, and the hoisting machines 401 can also be three or more than three and are uniformly distributed along the circumferential direction of the feeding pipe 100, so that the bottom end of the corrugated pipe 102 cannot be overturned when the bottom end of the corrugated pipe 102 is driven to lift. The driving mechanism 400 may also have other structures, for example, an electric hoist may also be used to drive the bottom end of the bellows 102 to move up and down. In addition, the feeding pipe 100 may also be of other telescopic structures, for example, a sleeve may be slidably sleeved outside the connecting pipe 101, the bottom end of the pulling rope 402 is connected to the top end of the sleeve, and the winch 401 controls the sleeve to slide up and down.

In some embodiments of the present invention, as shown in fig. 3, a dust suction port is formed on a side wall of the connection pipe 101, the dust suction port is communicated with the dust collector, and a filter screen 105 is disposed on the dust suction port. The filter screen 105 is arranged to pass dust but not bulk material and to prevent the bulk material from entering the cleaner. Of course, in some cases, the filter screen 105 may not be provided, and only the negative pressure generated by the vacuum cleaner is required to suck the dust, but not the bulk material.

In some embodiments of the present invention, as shown in fig. 3, a collar set is disposed on the outer sidewall of the corrugated tubing 102 corresponding to each pull-cord 402, and a plurality of collars 103 are arranged on each collar set along the axial direction of the corrugated tubing 102 for housing the pull-cords 402. Thereby, the corrugated pipe 102 is only expanded and contracted along the self axial direction, i.e. the vertical direction, and is not easy to bend or shift along the radial direction, so that the bulk materials can smoothly pass through the corrugated pipe 102.

In some embodiments of the present invention, as shown in FIG. 3, a second vibrator 104 is disposed on bellows 102. Because the inner side wall of the corrugated pipe 102 is of a corrugated structure, dust can be accumulated on the inner side wall of the corrugated pipe 102, and the second vibrator 104 is arranged, so that the dust can be separated from the inner side wall of the corrugated pipe 102 by the vibration of the second vibrator 104, and then the dust can be sucked by the dust collector in time.

In some embodiments of the present invention, as shown in FIG. 3, the edge of the bottom end of bellows 102 is circumferentially provided with dust shield 106. The dust cover 106 is arranged, so that the condition that dust is diffused into the storage bin 600 from the bottom end of the corrugated pipe 102 along the radial direction of the corrugated pipe 102 can be reduced, and the dust prevention effect is better.

In some embodiments of the present invention, dust boot 106 is angled downward away from the axial center of bellows 102, as shown in FIG. 3. The situation that dust is diffused into the bin 600 from the bottom end of the corrugated pipe 102 along the radial direction of the corrugated pipe 102 can be further reduced, so that the dust-proof effect is better.

In some embodiments of the present invention, as shown in FIG. 3, the second vibrator 104 is disposed on a dust cover 106. Further, the expansion and contraction of bellows 102 does not affect the mounting of second vibrator 104, so that second vibrator 104 is more firmly mounted.
