Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a self-circulation dust removal device for a conveyor. Background Technique

[0002] When a belt conveyor conveys powdery materials, a large amount of dust is generated due to the mutual transfer between belt conveyors (transfer stations) and when the belt conveyor enters other devices due to the falling of materials, which brings pollution to the environment. Therefore, the treatment of the working environment when a belt conveyor conveys powdery materials has been a research and treatment direction for many years;

[0003] However, most of the existing dust removal devices for conveyors use external dust collectors for purification treatment, but the external dust collectors need to consume a large amount of electric energy (dust removal fans) to suck the dust into the dust collector for purification.

[0004] Therefore, we propose that the self-circulation dust removal device for a conveyor can well solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a self-circulation dust removal device for a conveyor to solve the problem that most of the existing dust removal devices for conveyors use external dust collectors for purification treatment, but the external dust collectors need to consume a large amount of electric energy (dust removal fans) to suck the dust into the dust collector for purification proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a self-circulation dust removal device for a conveyor, including a belt conveyor, a sealing cover is installed on the top of the belt conveyor, and brackets are fixedly connected to the outside of the sealing cover at equal intervals. The belt conveyor is used for conveying powdery materials;

[0007] A chute pipe is fixed to the right side of the top of the sealing cover, and a return pipe is fixedly connected to the left side of the top of the sealing cover located on the left side of the chute pipe;

[0008] Sealing grooves are arranged at equal intervals on the top of the sealing cover, and a circulation pipe is fixed to the left side of the top of the sealing cover. Comb-shaped curtain screens are arranged on both the left and right sides of the inner wall of the sealing cover.

[0009] Preferably, the sealing cover is bolt-mounted on the top of the belt conveyor through a plurality of brackets. The chute pipe is communicated with the inside of the sealing cover, and the chute pipe is inclined.

[0010] Preferably, one end of the return pipe away from the sealing cover is fixedly connected to the left side of the chute pipe, and the inside of the return pipe is communicated with the inside of the chute pipe and the sealing cover respectively. The circulation pipe is communicated with the inside of the sealing cover.

[0011] Preferably, a plurality of the sealing grooves communicate with the interior of the bracket, and a cover plate is provided at the top of the sealing groove.

[0012] Preferably, the side surface of the belt conveyor is arranged in a "V" shape, the bottom of the comb-shaped curtain is butted against the top of the belt conveyor, rubber side baffles are symmetrically fixed on the inner wall of the bracket with respect to the center point of the comb-shaped curtain, and an inclined groove type sealing strip is fixedly connected to the bottom of the rubber side baffle.

[0013] Preferably, adjusting bolts penetrate through the interiors of the brackets on the left and right sides, and a baffle support is fixedly connected to the opposite ends of the two adjusting bolts.

[0014] Preferably, the adjusting bolts are in threaded connection with the belt conveyor, and one side of the baffle support away from the adjusting bolts is connected to the rubber side baffle.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The self-circulating dust removal device of this conveyor applies the principle of aerodynamics, adopts measures to control the pressure balance in the closed space and reduce the air flow velocity in the closed space, so that dust particles settle in the materials conveyed by the belt conveyor, and the dust gas is collected in the sealing groove. At the same time, by using the provided circulation pipe, the dust generated at the material dropping point flows back into the chute pipe, and circulates in turn. Thus, after multiple settlements, 99% of the dust particles settle down, and the environment is greatly improved. The specific content is as follows:

[0016] (1) When the belt conveyor transports powdery materials, when the materials are transferred to other belt conveyors or equipment through the chute pipe at each transfer station, a large number of fine particles are produced due to the collision of the materials in the chute pipe. At this time, since the materials occupy the space in the chute pipe, the air in the chute pipe is rapidly pushed downward by the materials and moves together with the powdery materials into other belt conveyors or equipment. When the materials suddenly stop and collide with other conveyors and equipment, the air flow direction changes rapidly, carrying a large number of fine particles to generate dust and dust-raising phenomena.

[0017] (2) The powdery materials overflowing outside the rubber baffle on the sealing groove at the material dropping point are all collected in the belt sealing groove under the action of the inclined groove type sealing strip. At this time, the dust removal device without power of the belt conveyor just collects and settles the dust and dust-raising generated in the above process, thus eliminating the dust phenomenon.

[0018] (3) When the materials in the chute pipe rapidly descend, the air in the chute pipe is discharged into the belt conveyor sealing groove, and a negative pressure area is formed in the chute pipe. Then, a return pipe is arranged above the front of the material dropping point in the chute pipe. The connection part between the return pipe and the sealing groove is exactly the positive pressure area generated at the material dropping point. The return pipe connects the positive pressure area with the negative pressure area of the chute pipe, so that the dust generated at the material dropping point flows back into the chute pipe and circulates in turn.

[0019] Furthermore, due to the expansion structure of the return pipe, the flow rate of the dust decreases when it enters the return pipe. Most of the dust particles settle in the belt material, and some return to the chute pipe.

[0020] (4) The dust that has not been processed by the return pipe device moves forward with the material all the time. During the conveying process, a comb-shaped curtain is arranged in the device. This curtain reduces the air flow rate and settles part of the dust. At the same time, the circulating pipe on the sealing groove of the conveyor expands the dust air flow to reduce the air flow rate, and most of the dust settles again. After multiple settlements, 99% of the dust particles settle down, and the environment is greatly improved. Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6 , the present utility model provides the following technical solution: a self-circulating dust removal device for a conveyor;

[0030] Embodiment 1: To solve the problem that most of the existing conveyor dust removal equipment in the prior art uses an external dust collector for purification treatment, but the external dust collector requires a large amount of power consumption (dust removal fan) to suck dust into the dust collector for purification. Therefore, the following solution is disclosed. For specific reference, see Figures 1-6 As shown in the figure, it includes a belt conveyor 1. A sealing cover 3 is installed on the top of the belt conveyor 1, and brackets 2 are fixedly connected to the outside of the sealing cover 3 at equal intervals. The belt conveyor 1 is used for conveying powdery materials.

[0031] A chute pipe 4 is fixed to the right side of the top of the sealing cover 3. The sealing cover 3 is bolted to the top of the belt conveyor 1 through a plurality of brackets 2. The chute pipe 4 is communicated with the inside of the sealing cover 3, and the chute pipe 4 is inclined. A return pipe 5 is fixedly connected to the left side of the top of the sealing cover 3 where the chute pipe 4 is located. Sealing grooves 7 are arranged at equal intervals on the top of the sealing cover 3. The plurality of sealing grooves 7 are communicated with the inside of the brackets 2, and a cover plate is arranged on the top of the sealing grooves 7. A circulation pipe 6 is fixed to the left side of the top of the sealing cover 3. One end of the return pipe 5 away from the sealing cover 3 is fixedly connected to the left side of the chute pipe 4, and the inside of the return pipe 5 is respectively communicated with the inside of the chute pipe 4 and the sealing cover 3. The circulation pipe 6 is communicated with the inside of the sealing cover 3. Comb-shaped baffle curtains 12 are arranged on both the left and right sides of the inner wall of the sealing cover 3.

[0032] When the belt conveyor 1 transports powdery materials, when the materials are transferred to other belt conveyors 1 or equipment through the chute pipe 4 at each transfer station, a large number of fine particles are produced due to the collision of the materials in the chute pipe 4. At this time, since the materials occupy the space of the chute pipe 4, the air in the chute pipe 4 is quickly pushed downward by the materials and moves together with the powdery materials into other belt conveyors 1 or equipment. When the materials suddenly stop and collide with other conveyors and equipment, the air flow direction changes rapidly, resulting in a large amount of fine particles being carried up to generate dust and dust-raising phenomena. The powder outside the rubber side baffle 9 on the sealing groove 7 at the material dropping point is all collected in the belt sealing groove 7 under the action of the inclined groove type sealing strip 8. At this time, the power-free dust removal device of the belt conveyor 1 just collects and settles the dust and dust-raising phenomena generated in the above process, thereby eliminating the dust phenomenon. At the same time, the materials in the chute pipe 4 quickly drop in the device, discharging the air in the chute pipe 4 into the belt machine sealing groove 7, and a negative pressure area is formed in the chute pipe 4. Then, a return pipe 5 is arranged at the upper front of the material dropping point in the chute pipe 4. The connection part between the return pipe 5 and the sealing groove 7 is exactly the positive pressure area generated at the material dropping point. The return pipe 5 connects the positive pressure area with the negative pressure area of the chute pipe 4. Then, the dust generated at the material dropping point flows back into the chute pipe 4 and circulates in turn. And because the return pipe 5 has a volume expansion structure, the flow rate of the dust decreases when it enters the return pipe 5, and most of the dust particles settle in the belt materials, and part of them flows back into the chute pipe 4.

[0033] Embodiment 2: Different from Embodiment 1, in this embodiment, the set circulation pipe 6 can be used for circulating sedimentation, thereby improving the sedimentation rate of dust. Specifically, refer to Figure 2 and Figure 5 As shown, the side of the belt conveyor 1 is arranged in a "V" shape, the bottom of the comb-shaped curtain 12 is butted against the top of the belt conveyor 1, rubber side baffles 9 are symmetrically fixed on the inner wall of the bracket 2 with respect to the center point of the comb-shaped curtain 12, and an inclined groove type sealing strip 8 is fixedly connected to the bottom of the rubber side baffle 9;

[0034] The dust that has not been processed by the return pipe 5 device advances with the material all the time. During the conveying process, a comb-shaped curtain 12 is arranged in the device. This curtain reduces the air flow velocity and settles part of the dust. At the same time, the circulation pipe 6 on the conveyor sealing groove 7 expands the dust air flow to reduce the air flow velocity, and most of the dust settles again. After multiple sedimentations, 99% of the dust particles settle down, and the environment is greatly improved.

[0035] Embodiment 3: Different from Embodiment 2, in this embodiment, by rotating the adjusting bolt 11, the rubber side baffles 9 on both sides can be moved, and can be adjusted according to different sizes of the comb-shaped curtain 12. Specifically, refer to Figure 2 As shown, adjusting bolts 11 penetrate through the interiors of the brackets 2 on the left and right sides, and a baffle support 10 is fixedly connected to the opposite ends of the two adjusting bolts 11. The adjusting bolt 11 is in threaded connection with the belt conveyor 1, and the side of the baffle support 10 away from the adjusting bolt 11 is connected to the rubber side baffle 9;

[0036] The user rotates the adjusting bolts 11 on the left and right sides with tools, so that the two adjusting bolts 11 drive the baffle supports 10 on both sides to move relatively or in the opposite direction, and drive the rubber side baffles 9 on both sides to move, so as to be able to adjust according to different sizes of the comb-shaped curtain 12.

[0037] The content not detailedly described in this specification belongs to the prior art well-known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
