Description

Technical Field

[0001] The utility model belongs to the technical field of vibrating screens, and particularly relates to a dust-free feeding type vibrating screening device. Background Art

[0002] A dust-free feeding station is a device for the automatic packaging and feeding of powder materials. It adopts advanced technologies and working principles to achieve dust-free, efficient, and precise material feeding. The design of the dust-free feeding station aims to solve the dust problem generated during the production and feeding of powder materials. Through a dust collection system, it effectively avoids dust flying, reduces material waste, eliminates the need to clean remote dust collection sites, protects workers, and prevents factory pollution. Existing dust-free feeding stations are mainly used for feeding and dust removal, and need to cooperate with other equipment to complete actual production, resulting in relatively high production input costs. For example, dust is generated during the feeding and vibrating screening of a vibrating screening device. The dust scatters outside the feeding port, causing environmental pollution. On the premise of ensuring environmental protection requirements and production requirements, it is necessary to configure a dust-free feeding station and a vibrating screen, which not only occupy a large floor area but also have a relatively large production input. Moreover, the screen meshes of existing circular vibrating screens are all designed with a horizontal structure, resulting in low screening efficiency during the vibrating screening process.

The vibrating seat 8 is arranged above the buffer pillar 11. A vibrating motor 9 is fixedly installed on the outer side of the vibrating seat 8. A matching mounting seat 12 is arranged on the vibrating seat 8. A vibrating screen cover 13 is installed inside the matching mounting seat 12. The vibrating screen cover 13 is connected to the dust-free feeding bin 1 through a connecting body 14. A filter box 2 is fixedly installed on the top surface of the dust-free feeding bin 1. A fan 3 is arranged above the filter box 2. A matching installation groove 22 is arranged at the feeding outlet of the dust-free feeding bin 1. An upper filter screen 19 is installed in a matching manner at the matching installation groove 22. A support grid 24 is installed inside the vibrating screen cover 13. A lower filter screen 23 is arranged above the support grid 24. A bottom plate 25 is arranged below the support grid 24. A baffle guiding plate 26 is arranged on the upper filter screen 19. A first discharge port 15 is arranged on the outer side of the connecting body 14. A second discharge port 16 and a third discharge port 17 are arranged on the outer side of the vibrating screen cover 13.

[0025] Among them, the upper filter screen 19 is designed with an inclined structure. The upper filter screen 19 is located inside the inner cavity of the connecting body 14. The connecting body 14 is a frustum structure with a larger upper part and a smaller lower part. The shape and specification of the upper filter screen 19 are consistent with the shape and specification of the inclined cross-section of the connecting body 14. A matching installation clamping end 27 is arranged at the end of the upper filter screen 19 close to the feed. A matching installation groove 22 is arranged at the feed of the dust-free feeding bin 1.

[0026] The size and specification of the matching installation clamping end 27 and the matching installation groove 22 are mutually adapted. Fixing holes are correspondingly machined in both the matching installation clamping end 27 and the matching installation groove 22. The upper filter screen 19 is fixedly installed through fixing screws, which is convenient for disassembly and assembly operations.

[0027] A plurality of baffle guiding plates 26 are arranged in a mutually staggered manner. The baffle guiding plate 26 is an arc-shaped structure. The first discharge port 15 is connected to the lower end of the upper filter screen 19. A blanking guiding plate 20 is arranged inside the first discharge port 15. The blanking guiding plate 20 has an inclined surface structure. A pull plate 21 is arranged at the lower end position of the first discharge port 15 for controlling the discharging condition of the first discharge port 15.

[0028] The position of the second discharge port 16 corresponds to the position of the lower filter screen 23. The position of the third discharge port 17 corresponds to the position of the bottom plate 25. Two vibrating motors 9 are arranged. A dust collecting cover 18 is arranged at the top inner position of the dust-free feeding bin 1.

[0029] A fixed installation base 7 is provided at the lower part of the filtration box 2 and is fixedly connected to the dust-free feeding bin 1 through bolts, facilitating quick disassembly and assembly. A feeding bin door 4 is installed on the dust-free feeding bin 1, and gas springs 5 are installed between both sides of the feeding bin door 4 and the outer wall of the dust-free feeding bin 1.

[0030] The working principle of the present utility model is as follows: The material to be screened is added from the dust-free feeding bin 1. The material undergoes basic screening through the upper filter screen 19, and the large particles screened out enter the first discharge port 15. The small particles fall on the lower filter screen 23 for further screening. During the feeding process, the fan 3 above the dust-free feeding bin 1 and the devices in the filtration box 2 filter the generated dust. Under the air extraction state of the fan 3, a certain negative pressure is obtained in the inner cavity of the working bin, and the dust generated during feeding is sucked into the filter to prevent leakage outside the box; The feeding bin door 4 is provided with gas springs 5, facilitating the operator to open it. Sealing strips are inlaid around the feeding bin door 4 to prevent the dust from flying out; The filtration system of the dust-free feeding station is an existing technology and will not be elaborated too much.

[0031] The present invention intends to adopt a combination method of an inclined upper filter screen 19 and a horizontal lower filter screen 23. The advantage of such a design is that most of the material can be screened out through the inclined screen, and a small part passes through the flat screen and is screened through the oscillation of the motor to avoid material accumulation. There are guard plates inside the inclined screen to prevent the material from spilling from both sides. The filter screen structure can also be multi-layered, and materials with different particle sizes can be collected.

[0032] When screening large particles, if the screening can be completed only by using the upper filter screen 19, the vibration motor 9 can also not be turned on, and the inclined screen does not need to oscillate through the motor. The gravity of the material makes it pass through the screen naturally, effectively reducing energy consumption.

[0033] The dust-free feeding station of the present utility model has a combined structure with a vibrating screen. The feeding port of the vibrating screen is provided with a dust-free feeding bin 1, which can effectively purify the dust generated during the feeding and vibration processes of the vibrating screen. The device has a small size and a small production input cost; The device is provided with two-stage filter screens. The upper filter screen 19 is designed with an inclined structure, and a blanking guide plate 20 is arranged on the filtering surface, which can effectively increase the screening area, extend the filtering time, and enhance the screening and filtering effect. A support grid 24 is arranged below the lower filter screen 23 to enhance the structural stability of the lower filter screen 23 and extend its service life.

[0034] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present utility model, may make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
