Preferably, the cross section of one end of the first guide plate, the second guide plate and the third guide plate is triangular.

Preferably, the number of the dust chambers is more than two.

Compared with the prior art, the beneficial effects of the utility model are that: the novel unpowered dust removal guide chute device has no energy consumption, no need of cleaning and no secondary pollution; the return pipe and the dust removing chamber are respectively provided with a guide plate, so that on one hand, a larger area is provided for the attachment of dust, and on the other hand, the flow of dust-containing airflow can be smoothly guided; the vibrators are respectively installed on the return pipe and the outer side wall of the dust removal chamber, dust is deposited on the pipe wall or the guide pipe wall to form blocks, the blocks are quickly and effectively separated through low-frequency vibration of the vibrators, and the blocks are conveyed away along with materials, so that the dust removal efficiency is high, and the effect is good.

Drawings

Fig. 1 is a schematic structural view of the novel unpowered dust removal baffle box device of the present invention.

In the drawings: 1. a belt conveyor; 2. a fully-sealed guide chute; 3. a blanking pipe; 4. a return pipe; 5. a first baffle; 6. a first vibrator; 7. a dust chamber; 8. a second baffle; 9. a third baffle; 10. a second vibrator; 11. a third vibrator; 12. damping dust curtain.

Detailed Description

A novel unpowered dust removal baffle box device as shown in fig. 1 in the attached drawings of the specification, including belt conveyor 1 and totally enclosed baffle box 2 erected above belt conveyor 1, the one end of totally enclosed baffle box 2 is equipped with blanking pipe 3, the low reaches of blanking pipe 3 are equipped with back flow pipe 4, the top of back flow pipe 4 communicates blanking pipe 3, set up first guide plate 5 in the back flow pipe 4, first vibrator 6 is installed to the back flow 4 lateral wall, the low reaches of back flow pipe 4 are equipped with clean room 7, and communicate with totally enclosed baffle box 2, set up second guide plate 8 and third guide plate 9 in two bodys of clean room 7 respectively, second vibrator 10 and third vibrator 11 are installed respectively to two bodys lateral walls of clean room 7, interval sets up damping dust-blocking curtain 12 in totally enclosed baffle box 2.

When the dust collecting device is used, materials enter the fully-sealed guide chute 2 from the blanking pipe 3 and fall on the conveying belt, impact airflow is generated when the materials fall through the blanking pipe 3, the airflow is diffused along the running direction of the conveying belt, the airflow is retarded and rebounded in the diffusion process by the front adjustable damping dust-blocking curtains 12 (the damping dust-blocking curtains 12 are arranged between the return pipe 4 and the dust chambers 7 at intervals), most of the airflow rebounds to enter the return pipe 4 and the dust chambers 7, the dusty airflow returns to the fully-sealed guide chute 2 again to generate continuous circulation due to the negative pressure influence of the dust chambers 7, the dusty concentration is increased continuously in the circulation process of the return pipe 4 and the dust chambers 7, and the first guide plate 5, the second guide plate 8 and the third guide plate 9 are respectively arranged in the return pipe 4 and the dust chambers 7, so that a larger area is provided for attaching dust on one hand, and the other hand, the dust energy is exhausted and attached to the pipe walls of the return pipe 4 and the dust removal chamber 7 and the plate walls of all the guide plates, the dust is deposited into blocks, when the dust reaches a certain thickness, the blocky dust can be thoroughly fallen off by starting the first vibrator 6 arranged on the outer side wall of the return pipe 4 and the second vibrator 10 and the third vibrator 11 respectively arranged on the outer side walls of the two pipe bodies of the dust removal chamber 7, the dust is conveyed away along with the material, the inner diameter of the pipe is recovered to the original size, the flow of the dust-containing air is not blocked, the residual dust-containing air continues to move forwards, and the dust can be gradually weakened under the retardation action of the adjustable damping dust-blocking curtain 12 arranged at the rear section and is finally exhausted.

The cross-sections of one ends of the first guide plate 5, the second guide plate 8 and the third guide plate 9 are triangular, so that the attachment area of dust can be further increased.

The number of the dust chambers 7 is more than two, so that dust in the dust-containing air can be thoroughly removed.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
