Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression material guide troughs, in particular to a non-powered environmentally friendly dust suppression material guide trough with modular design. Background Art

[0002] The guide chute is mainly used in belt conveyors. Installing the guide chute at the receiving end of the belt conveyor can concentrate the materials falling from the hopper to the middle of the conveyor belt before reaching the belt speed, preventing the materials from scattering outwards. At the same time, the dust can be decompressed, decelerated and settled, allowing a cleaner airflow to flow out from the outlet of the guide chute.

[0003] In recent years, as the country's requirements for environmental protection have become increasingly stringent, environmentally friendly dust suppression material guide troughs have become more and more commonly used in the coal, metallurgy, mining, and power industries. The sealing effect of environmentally friendly dust suppression material guide troughs is mainly dependent on the sealing plate. The traditional sealing plate is arranged on the inner side of the material guide trough shell. The lower part of the material guide trough shell is an inclined structure. The material is easy to fall on the sealing plate, which increases the wear of the sealing plate and shortens the service life. In addition, the sealing effect of the single-layer sealing plate is not good, and dust is easy to overflow. Therefore, the conveyor belt is not environmentally friendly and is easily punished by the environmental protection department. Because environmentally friendly dust suppression material guide troughs are non-standard products, the material guide troughs on the market generally have long development cycles, long production cycles, high development costs, and later upgrades and renovations. Difficulties and other problems; Chinese patent application No. 201621203235.1 discloses a non-powered dust suppression double-sealed material guide trough, including a material guide trough body, and also includes an expandable material guide trough inverted V-shaped top plate, modular combined material guide trough side plates, and dust suppression curtains. An inclined polyethylene liner is installed inside the material guide trough side plate for sealing, and a Y-shaped anti-overflow skirt is also installed on the outside of the adjustable clamp. Two sealing plates are required to increase the sealing components. The polyethylene liner will be severely worn first and has a short service life. The two wear degrees are different, which brings difficulties to replacement and maintenance, and the sealing structure is exposed to the outside and ages quickly. Therefore, a modularly designed non-powered environmentally friendly dust suppression material guide trough is proposed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a modularly designed non-powered environmentally friendly dust suppression material guide trough. The sealing structure is simple and adopts a designed inverted R-shaped sealing plate structure to effectively reduce the sealing components, which is equivalent to setting three seals to ensure the sealing effect. An outer shell is set to form a sealing cavity to protect the sealing structure and extend the service life, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modularly designed non-powered, environmentally friendly, dust-suppressing material guide trough, comprising a material guide trough shell, a conveyor belt, a sealing plate and a clamp, the sealing plate being arranged on the outer side of the material guide trough shell, the cross section of the sealing plate being arranged as an inverted R-shaped structure, the sealing plate being arranged with an inner skirt, a middle skirt and an outer skirt from the inside to the outside, the inner skirt, the middle skirt and the outer skirt forming three seals with the conveyor belt, the lower part of the sealing plate forming an upward bending part, the cross section of the material guide trough shell being arranged with a guide inclined section and a guide vertical section, the sealing plate being arranged vertically on the outside of the guide vertical section, the clamp being arranged on the outside of the sealing plate, and an angle steel being arranged on the clamp.

[0006] Furthermore, an outer shell is arranged on the outer side of the material guide trough shell, a sealed cavity is formed between the outer shell and the material guide trough shell, and the outer shell is mounted on the outer bracket by screws.

[0007] Furthermore, a roller is arranged on the outer bracket, and the width of the roller is smaller than the width of the conveyor belt.

[0008] Furthermore, a wear-resistant support plate is fixed to the outer shell by screws, and the wear-resistant support plate is parallel to the inclined surface of the conveyor belt.

[0009] Furthermore, the guide chute shells are assembled together by screws, a damping dust curtain is arranged inside the guide chute shell, and the upper part of the guide chute shell is connected to a top plate by screws, and the top plate is arranged as an arc structure.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The sealing structure is simple and adopts a designed inverted R-shaped sealing plate structure, which effectively reduces the sealing components, equivalent to setting three seals, ensuring the sealing effect, setting an outer shell to form a sealing cavity, protecting the sealing structure and extending the service life.

[0012] 2. The inclined guide section is used for the sliding of materials, and the vertical guide section increases the height of the guide trough, increases the capacity, and reduces the accumulation of materials on the guide trough shell, so that it can fall smoothly on the conveyor belt.

DETAILED DESCRIPTION

[0020] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] See also Figure 1-5The utility model provides a technical solution: a modularly designed non-powered environmentally friendly dust suppression material guide chute, comprising a material guide chute shell 5, a conveyor belt 13, a sealing plate 11 and a clamp 9. The sealing plate 11 is arranged on the outer side of the material guide chute shell 5. When conveying materials normally, the contact between the materials and the sealing plate 11 can be effectively reduced, the wear between the materials and the sealing plate 11 can be reduced, and the service life of the sealing plate 11 can be extended. The cross-section of the sealing plate 11 is arranged in an inverted R-shaped structure. The sealing plate 11 is provided with an inner skirt 16, a middle skirt 15 and an outer skirt 14 from the inside to the outside. The inner skirt 16, the middle skirt 15 and the outer skirt 14 form three seals with the conveyor belt 13. This structure is equivalent to providing three sealing structures through a sealing plate 11, which can not only reduce the sealing components, but also have a good sealing effect. The inner skirt 16 plays a role in isolating materials and most of the dust, and part of Dust enters the wall outside the inner skirt 16 and is sealed again through the middle skirt 15. The third seal of the inner skirt 16 can effectively solve the problem of dust escape. The lower part of the sealing plate 11 forms an upward bending portion 17, which is easy to deform and can deform along the inclined surface of the conveyor belt 13, and has strong adaptability. The cross-section of the guide trough shell 5 is provided with a guide inclined section 8 and a guide vertical section 12. The guide inclined section 8 is used for the sliding of materials. The guide vertical section 12 increases the height of the guide trough, increases the capacity, and reduces the accumulation of materials on the guide trough shell 5, so that it can fall smoothly on the conveyor belt 13. The sealing plate 11 is vertically arranged on the outside of the guide vertical section 12, and the clamp 9 is arranged on the outside of the sealing plate 11. The clamp 9 is provided with an angle steel 10, and the sealing plate 11 is pressed by the angle steel 10 to prevent loosening, thereby ensuring the safety of the sealing structure.

[0022] An outer shell 2 is arranged on the outside of the material guide trough shell 5, and a sealed cavity 1 is formed between the outer shell 2 and the material guide trough shell 5. The outer shell 2 plays a role in protecting the external structure of the material guide trough. At the same time, the formed sealed cavity 1 prevents the entry of external dust, and the sealing plate assembly is protected by the material guide trough shell 5. The outer shell 2 is mounted on the outer bracket 6 by screws.

[0023] The outer support 6 is provided with a roller 4, the width of which is smaller than the width of the conveyor belt 13. The size of the roller 4 is reduced without affecting the rolling support for the material, thereby reducing the weight and manufacturing cost of the equipment.

[0024] A wear-resistant support plate 3 is fixed to the outer shell 2 by screws. The wear-resistant support plate 3 is parallel to the inclined surface of the conveyor belt 13. The wear-resistant support plate 3 supports both sides of the conveyor belt 13 to ensure that the conveyor belt 13 can be transported safely and stably.

[0025] The guide trough shell 5 is assembled together by screws, thus dividing the dust suppression guide trough into several independent modules. The function or performance of each module is relatively independent and can be independently designed, manufactured and assembled. The modular design allows production personnel to continuously optimize and conduct in-depth research on the process to avoid unnecessary risks of failure, making the manufacturing process very mature and more stable. A damping dust curtain 18 is arranged in the guide trough shell 5, and the upper part of the guide trough shell 5 is connected to a top plate 7 by screws, and the top plate 7 is arranged as an arc structure.

[0026] When in use: unify the length and cross-sectional interface of each section of the material guide chute. The site can select the appropriate number of sections of the material guide chute according to the site conditions and space. The number of supporting buffer equipment required for installation can be selected according to the length of the discharge chute. In actual applications, a primary circulation pressure relief device, a secondary circulation pressure relief device and an inspection port are set. The specific design position is set according to the actual situation.

[0027] The basic principles, main features and advantages of the present invention are shown and described above. Without departing from the spirit and scope of the present invention, the present invention may also be subject to various changes and improvements, which are all within the scope of the present invention to be protected.
