Description

Technical Field

[0001] This invention relates to the technical field, and in particular to a dust suppression device for a dust removal belt conveyor discharge chute. Background Technology

[0002] The guide chute is mainly used for belt conveyors. When the guide chute is installed at the receiving point of the belt conveyor, the material falling from the hopper can be concentrated in the middle of the conveyor belt before reaching the belt speed, thus preventing the material from spilling outwards. The existing method for treating dust inside the feed chute of the dust removal conveyor belt typically involves using a dust collector fan. The fan draws dust-laden air from the feed chute into the dust collector's filter bags, where the dust is filtered out. Clean air is then released into the atmosphere. However, the dust adsorbed inside the filter bags, due to the high humidity of the dust-laden air, causes the filter bags to become covered with wet dust in a short time, reducing their permeability and consequently decreasing the dust removal efficiency. This results in a large amount of dust being emitted from the feed chute, polluting the environment. Furthermore, cleaning the conveyor belt usually involves disassembling and washing it after operation, which is time-consuming and labor-intensive. Therefore, improvements are needed. Summary of the Invention

The pressing unit includes a pressing column fixedly connected to the bottom of the pressing plate. The bottom of the pressing column extends into the interior of the dust suppression chamber and abuts against the top of the rotating unit. A first flexible spring is movably connected to the outer wall of the pressing column.

[0009] As a preferred embodiment of the dust removal belt discharge port guide chute dust suppression device of the present invention, wherein: the installation pipe is fixedly connected to the rear end of the dust suppression bin, the interior of the installation pipe is movably connected to the adsorption plate, the end of the adsorption plate away from the dust suppression bin is fixedly connected to the bidirectional screw, the outer wall of the bidirectional screw is threadedly sleeved with the connecting shaft, the connecting shaft is sleeved with the second belt, and the interior of the connecting shaft near the dust suppression component is movably engaged with a fixing block fixedly connected to the bottom of the installation pipe, and the bottom of the installation pipe near the dust suppression bin is connected to the placement bin.

[0010] As a preferred embodiment of the dust removal belt discharge port guide chute dust suppression device of the present invention, wherein: the drive motor is connected to two rotating units via a first belt, the first connecting shaft is connected to the rotating unit via a second belt, the first connecting shaft is connected to the connecting shaft via a second belt, and the drive motor is fixedly connected to the rear end of the dust suppression chamber.

[0011] As a preferred embodiment of the dust removal belt discharge port guide chute dust suppression device of the present invention, wherein: the bottom of the filter bag is fixedly connected to the top of the placement plate, the top of the filter bag is fixedly connected to the movable unit, the top of the movable unit is in contact with the eccentric wheel, and the outer side of the bottom end of the movable unit is in contact with an abutting frame that is fixedly connected to the inner wall of the dust suppression chamber.

[0012] As a preferred embodiment of the dust removal belt discharge port guide chute dust suppression device of the present invention, the movable unit includes a movable plate fixedly connected to the top of the filter bag, and a second flexible spring fixedly connected to the top of the dust suppression chamber on both sides of the top of the movable plate. The four corners of the bottom of the movable unit are provided with extrusion protrusions that are adapted to the four corners of the top of the contact frame, and the end of the two that are adapted to each other is opened at an angle.

[0013] As a preferred embodiment of the dust removal belt discharge port guide chute dust suppression device of the present invention, wherein: the scraping plate is fitted and connected to the upper end of the dust suppression chamber cavity, the scraping plate is triangular in shape and the bottom is pointed, the top two sides of the scraping plate are fixedly connected to the top of the dust suppression chamber cavity, the middle end of the top surface of the scraping plate is fixedly connected to the connecting rope, and the top of the connecting rope is fixedly connected to the bottom of the pressing plate.

[0014] As a preferred embodiment of the dust removal belt discharge port guide trough dust suppression device of the present invention, wherein: the outer wall of the outer end of the rotating shaft located outside the dust suppression chamber is sleeved with the first belt, and the surface of the inner end of the rotating shaft located inside the dust suppression chamber is sleeved with eccentric wheels that respectively abut against the pressing column and the movable plate.

[0015] As a preferred embodiment of the dust removal belt discharge port guide chute dust reduction device of the present invention, wherein: the bottom surface of the pressing column is arc-shaped and abuts against the outer wall of the eccentric wheel.

[0016] The beneficial effects of this invention are as follows: By combining a rotating unit and a filter assembly, the filter bag is pressed and twisted. During dust suppression, the filter bag is rotated and pressed, causing deformation and vibration of the dust inside its outer wall, which then falls outwards. When the eccentric wheel rotates via the rotating shaft, its bottom presses down on the top of the movable plate, while the four corners of the bottom of the movable plate press down on the four corners of the top of the contact frame. This causes the movable plate to move the filter bag downwards and twist it. By deforming the outer wall of the filter bag, the dust inside is vibrated and falls outwards, improving the air permeability of the filter bag and enhancing the subsequent dust suppression effect.

[0017] This invention, through the coordinated arrangement of a rotating unit and a water mist assembly, achieves intermittent water mist spraying inside the dust suppression chamber. This avoids the waste of water resources caused by continuous water mist spraying and prevents the formation of condensation beads from the water mist and dust mixture inside the chamber, which would otherwise reduce the dust suppression effect. When the eccentric wheel rotates, the protruding part of its outer wall does not contact the bottom of the pressing column. The pressing column drives the pressing plate and four corrugated pipes to move downwards together. The downward compression of the corrugated pipes presses the sponge block inside, and the water inside is sprayed downwards into the dust suppression chamber through the water mist nozzle. The rotation of the eccentric wheel causes intermittent water spraying, avoiding the waste of water resources caused by continuous spraying and the accumulation of water and dust mixture inside the dust suppression chamber, which would make subsequent cleaning inconvenient.

[0018] This application utilizes a combination of scraping and adsorption components to adsorb dust inside the dust-suppressing chamber, improving its cleanliness and preventing excessive dust accumulation that could lead to mixing of cleaned and uncleaned air, thus reducing dust suppression effectiveness. The upward movement of the water outlet unit causes the connecting rope to move the scraping plate upwards. Conversely, when the pressing plate moves downwards due to the pressing column and the first flexible spring, the scraping plate, through the interaction of the two first spring telescopic tubes, scrapes the inner wall of the dust-suppressing chamber downwards, causing the dust to fall to the top of the placement plate. Then, the second belt drives the connecting shaft to rotate. The connecting shaft, due to its threaded connection with the bidirectional screw, causes the adsorption plate to move left and right, resulting in the adsorption plate near the dust-suppressing chamber adsorbing and moving the dust on top of the placement plate into the chamber. A connecting groove is provided at the bottom of the mounting tube and the top of the placement chamber to ensure the adsorption of dust from the top of the placement plate.

The drive assembly 500 includes a drive motor 501 disposed on the upper back of the dust collection chamber 201, a first belt 502 disposed on the output end of the drive motor 501, a first connecting shaft 503 disposed on the rear wall of the dust collection chamber 201, a second belt 504 disposed on the first connecting shaft 503, and a third belt 505 disposed on the second belt 504. The filter assembly 600 includes a filter bag 601 disposed on a placement plate 204, a movable unit 602 disposed on the filter bag 601, and an abutment frame 603 disposed at the bottom of the movable unit 602. The scraping assembly 700 includes a scraping plate 701 disposed at the upper end of the inner cavity of the dust collection chamber 201, a first spring telescopic tube 702 disposed on the scraping plate 701, and a connecting rope 703. The rotating unit 800 includes a rotating shaft 801 disposed on the dust settling chamber 201 and an eccentric wheel 802 disposed on the outer wall of the rotating shaft 801.

[0033] The outer wall of the lower end of the inner cavity of the dust settling chamber 201 is sloping. The top of the dust settling chamber 201 is fixedly connected to the water mist assembly 300. The placement plate 204 is fixedly connected to the middle end of the inner cavity of the dust settling chamber 201. The conveying pipe 203 connects the two dust settling chambers 201. The water outlet unit 301 includes four corrugated pipes 301a fixedly connected to the four corners of the top of the dust settling chamber 201. Sponge blocks 301b are installed inside the corrugated pipes 301a. The bottom end of the corrugated pipes 301a extends into the interior of the dust settling chamber 201 and is fixedly installed with a water mist nozzle 301d. The top of the corrugated pipe 301a is fixedly connected to a pressing plate 301c that is connected to the top of the pressing unit 302. The pressing unit 302 includes a pressing column 302a that is fixedly connected to the bottom of the pressing plate 301c. The bottom of the pressing column 302a extends into the interior of the dust collection chamber 201 and abuts against the top of the rotating unit 800. A first flexible spring 302b is movably connected to the outer wall of the pressing column 302a. The upper and lower ends of the first flexible spring 302b are fixedly connected to the pressing plate 301c and the top of the dust collection chamber 201 from top to bottom, respectively.

[0034] Through the coordinated operation of structures such as the dust settling chamber 201 and the conveying pipe 203, the dust collection chamber 202 collects the filtered and settled dust inside the dust settling chamber 201. The placement plate 204 supports the filter bag 601 to ensure its stability. The conveying pipe 203 collects and discharges the settled gas. The placement plate 204 divides the interior of the dust settling chamber 201 into upper and lower areas, with the lower area having a larger dust volume than the upper area. Through the coordinated operation of structures such as the corrugated pipe 301a and the water mist nozzle 301d, the pressing column 302a drives the pressing plate 301c. When the pressure plate 301c moves downward, it will drive the four corrugated pipes 301a to move downward together. As the corrugated pipes 301a are squeezed and moved downward, they will press the sponge block 301b inside. The water source at the end of the squeezed sponge block 301b will be sprayed downward into the dust settling chamber 201 through the water mist nozzle 301d. With the cooperation of the rotating unit 800, the water source will be sprayed intermittently to avoid the waste of water source due to continuous spraying and to prevent the water and dust mixture inside the dust settling chamber 201 from increasing and making it difficult to clean later. Example

[0035] Reference Figures 7-10 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] The mounting tube 401 is fixedly connected to the rear end of the dust settling chamber 201. The interior of the mounting tube 401 is movably connected to the adsorption plate 403. The end of the adsorption plate 403 away from the dust settling chamber 201 is fixedly connected to the bidirectional screw 404. The outer wall of the bidirectional screw 404 is threadedly connected to the connecting shaft 405. The connecting shaft 405 is sleeved with the third belt 505. The interior of the connecting shaft 405 near the dust settling component 200 is movably engaged with a fixing block fixedly connected to the bottom of the mounting tube 401. The bottom end of the mounting tube 401 near the dust settling chamber 201 is connected to the placement chamber 402.

[0037] The drive motor 501 is connected to two rotating units 800 via a first belt 502. The first connecting shaft 503 is connected to the rotating unit 800 via a second belt 504. The first connecting shaft 503 is connected to the connecting shaft 405 via a third belt 505. The drive motor 501 is fixedly connected to the rear end of the dust settling chamber 201. The bottom of the filter bag 601 is fixedly connected to the top of the placement plate 204. The top of the filter bag 601 is fixedly connected to the movable unit 602. The top of the movable unit 602 is in contact with the eccentric wheel 802. The outer side of the bottom end of the movable unit 602 is in contact with a contact frame 603 that is fixedly connected to the inner wall of the dust settling chamber 201.

[0038] With the cooperation of structures such as the mounting tube 401 and the connecting shaft 405, when the third belt 505 drives the connecting shaft 405 to rotate, the connecting shaft 405, due to its threaded connection with the bidirectional screw 404, will cause the adsorption plate 403 to move left and right. This allows the adsorption plate 403, with one end near the dust settling chamber 201, to adsorb the dust on the top of the placement plate 204 and move it into the interior of the placement chamber 402. A connecting groove is provided at the bottom of the mounting tube 401 and the top of the placement chamber 402 to ensure the adsorption effect.

[0039] When the drive motor 501 starts, it will drive the rotating shaft 801 to rotate via the first belt 502. At the same time, the rotating shaft 801 will drive the first connecting shaft 503 to rotate via the second belt 504. The first connecting shaft 503 will drive the connecting shaft 405 to rotate via the third belt 505, thus achieving the effect of mutual cooperation between the structures. Through the cooperation of the filter bag 601 and the contact frame 603, the intermittent rotation of the eccentric wheel 802 will press the movable unit 602 downward. The bottom end of the movable unit 602 will abut the top of the contact frame 603. When the movable unit 602 and the contact frame 603 come into contact, the movable unit 602 will drive the filter bag 601 to move downward and twist. By squeezing and bending the filter bag 601, the dust adhering to its outer wall will be shaken off and fall downward for cleaning. Example

[0040] Reference Figures 7-8 This is the third embodiment of the present invention, which is based on the previous embodiment.

[0041] The scraper plate 701 is fitted and connected to the upper end of the inner cavity of the dust collection chamber 201. The scraper plate 701 is triangular in shape and pointed at the bottom. The top two sides of the scraper plate 701 are fixedly connected to the first spring telescopic tube 702 connected to the top of the inner cavity of the dust collection chamber 201. The middle end of the top surface of the scraper plate 701 is fixedly connected to the connecting rope 703. The top of the connecting rope 703 is fixedly connected to the bottom of the pressing plate 301c.

[0042] The outer wall of the rotating shaft 801 located on the outside of the dust settling chamber 201 is sleeved with the first belt 502. The surface of the rotating shaft 801 located inside the dust settling chamber 201 is sleeved with an eccentric wheel 802 that respectively abuts against the pressing column 302a and the movable plate 602a.

[0043] The bottom surface of the pressing column 302a is arc-shaped and abuts against the outer wall of the eccentric wheel 802. The movable unit 602 includes a movable plate 602a fixedly connected to the top of the filter bag 601. The top two sides of the movable plate 602a are fixedly connected to a second flexible spring 602b fixedly connected to the top of the inner cavity of the dust collection chamber 201. The four corners of the bottom of the movable unit 602 are provided with pressing protrusions that are adapted to the four corners of the top of the abutment frame 603, and the end of the two that are adapted to each other is opened at an angle.

[0044] Through the cooperation of the structures 601a and the second flexible spring 602b, the rotation of the eccentric wheel 802 will press the entire movable plate 602a downwards. The four corners of the bottom surface of the movable plate 602a will abut against the four corners of the top surface of the contact frame 603, causing the movable plate 602a to move the filter bag 601 downwards and twist, thus facilitating subsequent dust removal. Through the cooperation of the scraping plate 701 and the connecting rope 703, when the water outlet unit 301 moves upwards, the connecting rope 703 will drive the scraping plate 701. When the two spring telescopic tubes 702 move upward together, they will be compressed. Conversely, when the pressing plate 301c moves downward due to the pressing column 302a and the first flexible spring 302b, the scraping plate 701 will move downward through the cooperation of the two spring telescopic tubes 702. This scrapes the inner wall of the dust collection chamber 201 downward, preventing the upper part of the inner wall of the dust collection chamber 201 from accumulating too much dust and water mist mixture, which would be detrimental to subsequent cleaning and would also greatly reduce the dust collection effect.

[0045] The rotating shaft 801 will rotate along with the first belt 502. The rotating shaft 801 will cause the eccentric wheel 802 to intermittently contact the bottom of the movable plate 602a and the pressing column 302a. When the cam on the outer wall of the eccentric wheel 802 rotates to the top of the movable plate 602a, the pressing column 302a will move downwards and press down through the first flexible spring 302b, squeezing the water source inside the water outlet unit 301. Conversely, when the protruding part of the outer wall of the eccentric wheel 802 contacts the bottom of the pressing column 302a, the movable plate 602a will move upwards due to the elastic force of the second flexible spring 602b, thereby achieving the squeezing and twisting action on the outer wall of the filter bag 601. The design of the bottom surface of the pressing column 302a will further facilitate the subsequent rotation and pressing action of the eccentric wheel 802.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
