Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, and particularly to a sealing device for a conveyor. Background Art

[0002] Due to the advantages of low cost, low maintenance cost, large conveying capacity, etc., conveyors have now been widely used in industries such as metallurgy, steel plants, and coal. However, in actual production operations, when the conveyed materials are materials that are prone to generating odors or dust, such as dried sludge and coal gangue, their disadvantages are quite obvious. The odors or dust will diffuse in the air, seriously affecting the surrounding environment and air quality. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a sealing device for a conveyor. By arranging a sealing device on the conveyor, the dust or odor generated by the conveyed materials can be prevented from spreading outwards, protecting the environment and air quality around the conveyor.

[0004] To achieve the above purpose, the utility model provides a sealing device for a conveyor. The sealing device includes a plurality of covers and a film body. The film body is made of a flexible material. The covers are arranged outside the conveyor. The plurality of covers are arranged at intervals along the extension direction of the conveyor. An interval area is formed between two adjacent covers. The film body is located between the adjacent covers and covers the interval area.

[0005] By adopting the solution in the present application, through the combined use of the covers and the film body made of a flexible material, the covers are arranged in sequence in the extension direction, and the interval area formed between two adjacent covers is covered by the film body, thereby forming a certain degree of shielding and sealing for the conveyor, preventing the conveyed materials from polluting the surrounding environment and air. At the same time, the production cost and maintenance cost of the film body are both relatively low. During the maintenance process, it is only necessary to open the film body. After the maintenance is completed, a new film body can be replaced to cover the interval area. Thus, not only the disassembly and assembly of the sealing device are facilitated, but also the maintenance of the conveyor is facilitated.

[0006] Optionally, in the width direction of the conveyor, the cross-section of the cover is in a portal structure.

[0007] The sealing device further includes a plurality of support cylinders for supporting the film body. The support cylinders are arranged between two adjacent covers. In the width direction, the top of the portal structure has two corner positions, and the support cylinders are opposite to the corresponding corner positions on the side. In this way, the film body can be supported to the corner positions by the support cylinders, and thus the film body can be supported at the corner positions by the support cylinders, increasing the stability of the film body structure.

[0008] Optionally, in the width direction, fixing members are provided on both sides of the conveyor to fix the bottom end of the film body. By means of the fixing members provided on both sides of the conveyor, the bottom end of the film body can be pressed tightly, facilitating the installation and disassembly of the film body.

[0009] Optionally, in the width direction, on one side of the conveyor in the width direction, a fixing member is provided to fix the bottom end of the film body; on the other side, a film cylinder for winding the film body is provided, and the film cylinder can rotate relative to the conveyor, and the rotation axis of the film cylinder extends in the same direction as the conveyor. Thus, in the width direction, after the film body is pulled out by the film cylinder provided on one side of the conveyor, passes through the covering interval area, and is fixed to the fixing member on the other side of the conveyor. In this way, the installation process of the film body can be further simplified. When the film body needs to be replaced, it only needs to cut the film body to be replaced, pull the film body from the film cylinder to the other side of the conveyor, and form a fixed connection with the fixing member.

[0010] Optionally, the sealing device includes two turning cylinders. In the width direction, the two turning cylinders are arranged on both sides of the conveyor and are in contact with the surface of the film body away from the conveyor; in the height direction, the turning cylinder is located below the corresponding support cylinder. In this way, the support cylinder is arranged on the upper side and is located on the side of the film body close to the conveyor to support the film body. The turning cylinder is arranged below the support cylinder and is in contact with the surface of the film body away from the conveyor, so as to play a role in limiting the film body on the outer side of the film body. In the height direction, the lowest position of the turning cylinder defines the lowest point of the film body, and the highest position of the support cylinder defines the highest point of the film body; this can form an approximate portal structure for the flexible film body, so as to match the structure of the cover body, avoid deformation of the film body, and ensure that the film body can cover the interval area.

[0011] Optionally, in the extending direction of the conveyor, the length between two adjacent cover bodies is defined as the interval length;

[0012] The axial length of the turning cylinder matches the interval length, and the axial length of the support cylinder matches the interval length.

[0013] Thus, the support cylinder and the turning cylinder can form complete support and limitation in the part where the film body covers the interval area, further avoiding deformation of the film body.

[0014] Optionally, in the width direction, the fixing member is located on the side of the corresponding turning cylinder away from the conveyor, and the film cylinder is located on the side of the corresponding turning cylinder away from the conveyor. Thus, the film cylinder and the fixing member hold the bottom of the film body, and the two turning cylinders are located on the side of the corresponding film cylinder and the fixing member close to the conveyor and limit the film body, so that a reverse stop can be formed on the film body in the pulling direction, making the structure of the film body more stable.

[0015] Optionally, the fixing member includes a magnetic body and a fitting body; the bottom of the film body is adsorbed between the magnetic body and the fitting body on the corresponding side. By using the magnetic adsorption method, the film body can be fixed more quickly, further improving the replacement efficiency of the film body.

[0016] Optionally, the cover body includes an inner plate and an outer plate, the inner plate and the outer plate are arranged at intervals, and the outer plate is located on the side of the inner plate away from the conveyor; in the axial direction of the film cylinder, the film body extends beyond both ends of the film cylinder, and the part of the film body extending beyond the film cylinder is used as the side part of the film body, and the two side parts are embedded between the inner plate and the outer plate on the corresponding side. By sandwiching the two side parts of the film body between the inner plate and the outer plate, a double-layer cover body can be set to limit and guide the two side parts of the film body. At the same time, by overlapping the two side parts of the film body with the cover body, a gap between the film body and the cover body can be avoided.

[0017] Optionally, the sealing device further includes a bottom plate, and the bottom of the cover body is welded to the bottom plate; the cover body, the film body and the bottom plate enclose a cavity, and the conveyor is located in the cavity. By providing the bottom plate, the bottom of the cover body can be welded to the bottom plate, thereby enclosing a cavity approximately spaced from the outside. Description of the Drawings

[0025] To enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0026] Please refer to Figures 1-4 , Figure 1 which is a schematic structural diagram of the sealing device of the conveyor in the embodiment of the present utility model; Figure 2 which is a sectional view in the width direction of the conveyor; Figure 3 which is Figure 2 a partial structural diagram of , with the cover body part hidden; Figure 4 which is Figure 2 a partial structural diagram of , with the support cylinder part hidden.

[0027] As shown in the figure, the present utility model provides a sealing device for a conveyor 1. Referring to Figure 1 and Figure 2 , the sealing device includes a plurality of cover bodies 2 and a membrane body 3. The cover bodies 2 are sleeved outside the conveyor 1. The conveyor 1 can be arranged on the ground or on the bottom plate 8. When the conveyor 1 is arranged on the bottom plate 8, the bottom plate 8 plays a role in supporting the conveyor 1; that is, in a specific implementation, the sealing device further includes a bottom plate 8, and the bottom of the cover body 2 is welded to the bottom plate 8; the cover body 2, the membrane body 3 and the bottom plate 8 enclose a cavity, and the conveyor 1 is located in the cavity. By providing the bottom plate 8, the bottom of the cover body 2 can be welded to the bottom plate 8, thereby enclosing the cavity.

[0028] A plurality of cover bodies 2 are arranged at intervals along the extending direction of the conveyor 1 (the conveyor 1 includes a conveyor belt for transporting materials, and the extending direction of the conveyor 1 is the extending direction of the conveyor belt, that is, Figure 1 the left - right direction in ) to form an interval area. The interval area has a certain size in the extending direction of the conveyor 1, which can be adjusted by those skilled in the art; the membrane body 3 is located between adjacent cover bodies 2 and covers the interval area, so that the membrane body 3 and the cover bodies 2 can jointly cover the conveyor 1 in the extending direction of the conveyor 1. The cover body 2 is made of a metal material, and the membrane body 3 is made of a flexible material. For example, the membrane body 3 is a PVC membrane; in some optional ways, The film body 3 is made of a transparent material, so that the conveying state of the conveyor 1 can be conveniently observed.

[0029] By adopting the solution in the present application, through the combined use of the cover body 2 and the film body 3 made of flexible material, the cover bodies 2 are arranged in sequence in the extending direction, and the spaced area formed between two adjacent cover bodies 2 is covered with the film body 3, so as to form a certain degree of shielding and sealing for the conveyor 1, preventing the conveyed materials from polluting the surrounding environment and air. At the same time, the production cost and maintenance cost of the film body 3 are relatively low. After the maintenance is completed, it is only necessary to replace the new film body 3 to cover the spaced area. Thus, not only the disassembly and assembly of the sealing device are facilitated, but also the maintenance of the conveyor 1 is facilitated.

[0030] In a specific embodiment, refer to Figures 2 to 4 , in the width direction of the conveyor 1 (the width direction here is Figure 2 the left-right direction, that is, the width direction is perpendicular to the extending direction of the conveyor 1, which is perpendicular to Figure 1 the paper surface direction), the cross-section of the cover body 2 is in a portal structure. Of course, in addition to the portal structure, the cross-section of the cover body 2 can also be a semi-circular structure, a triangular structure or other shapes, and those skilled in the art can select according to needs.

[0031] When the cross-section of the cover body 2 is in a portal structure, in the width direction, the top of the cover body 2 has two corner positions 21; specifically, the cover body 2 has a horizontal section 22 and a vertical section 23. The horizontal section 22 extends along the width direction of the conveyor 1, and the vertical section 23 extends along the height direction of the conveyor 1. The vertical section 23 is perpendicular to the horizontal section 22 and is connected to both ends of the horizontal section 22. The bottom of the vertical section 23 can be directly or indirectly fixedly connected to the ground, or welded to the bottom plate 8 to form a fixed connection. The corner position 21 refers to the position where the horizontal section 22 and the vertical section 23 are joined.

[0032] The sealing device further includes a plurality of support cylinders 9, and the cylindrical surface of the support cylinder 9 is used to support the film body 3; the two ends of the support cylinder 9 in the extending direction of the conveyor 1 are directly or indirectly fixed to the corresponding side of the cover body 2 respectively. That is, the support cylinder 9 is arranged between two adjacent cover bodies 2, and the support cylinder 9 is axially opposite to the corresponding corner position 21 on the corresponding side; that is to say, a projection of the sealing device in its extending direction forms a state as shown in Figure 2 . The projection of the cylindrical surface of the support cylinder 9 in contact with the film body 3 substantially overlaps with the projection of the corner position 21 of the cover body 2. The meaning of "substantially overlapping" here includes the situation of complete overlap and a certain gap between the two projections. In this way, the flexible film body 3 can be supported to the corner position 21 through the support cylinder 9, and thus the film body 3 can be supported at the corner position 21 by the support cylinder 9, increasing the structural stability of the film body 3.

[0033] In some alternative embodiments, in the width direction, fixing members 5 are provided on both sides of the conveyor 1 to fix the bottom end of the film body 3. Through the fixing members 5 provided on both sides of the conveyor 1, the fixing members 5 are directly or indirectly fixed to the ground or directly or indirectly fixed to the bottom plate 8. The fixing members 5 can press the bottom end of the film body 3, thereby applying a tensile force to both ends of the flexible film body 3 in the width direction. Thus, the installation and disassembly of the film body 3 can be facilitated. In addition, by applying a tensile force to both ends of the film body 3 through the fixing members 5, under the support of the support cylinder 9, the direction of the tensile force is downward along the support cylinder 9, so that the flexible film body 3 can be tightened to obtain a certain structural strength.

[0034] In some other alternative embodiments, in the width direction, a fixing member 5 is provided on one side of the conveyor 1 to fix the bottom end of the film body 3; a film cylinder 6 for winding the film body 3 is provided on the other side. The film cylinder 6 can rotate relative to the conveyor 1, and the rotation axis of the film cylinder 6 extends in the same direction as the conveyor 1. Specifically, a cylinder support 10 is fixed on the ground or the bottom plate 8, and the film cylinder 6 is rotatably connected to the cylinder support 10. The film body 3 is pre-wound on the film cylinder 6 to form a bundle. When the conveyor 1 needs to be repaired, after opening a certain film body 3 for repair, a new film body 3 is unrolled from the film cylinder 6 to cover the interval area, that is, the film sealing operation is performed again. Thus, in the width direction, the film body 3 can be pulled out from the film cylinder 6 provided on one side of the conveyor 1, and after covering the interval area, it is fixed to the fixing member 5 on the other side of the conveyor 1. In this way, the installation process of the film body 3 can be further simplified. When the film body 3 needs to be replaced, after cutting the film body 3 to be replaced, the new film body 3 is pulled out from the film cylinder 6 to the other side of the conveyor 1 and fixedly connected to the fixing member 5.

[0035] As a specific embodiment, the fixing member 5 includes a magnetic body and a fitting body; the bottom of the film body 3 is adsorbed between the magnetic body and the fitting body on the corresponding side. By adopting the magnetic adsorption method, the film body 3 can be fixed more quickly, and the replacement efficiency of the film body 3 can be further improved. Of course, in addition to the magnetic adsorption method, other methods such as crimping and clamping can also be used to form a fixed connection at the bottom end of the film body 3.

[0036] In the above-described embodiment, the sealing device further includes two steering cylinders 7, and the two steering cylinders 7 are also fixed to the drum bracket 10; in the width direction, the two steering cylinders 7 are arranged on both sides of the conveyor 1 and are in contact with the surface of the film body 3 away from the conveyor 1; that is to say, the difference between the support cylinder 9 and the steering cylinder 7 is that the support cylinder 9 is arranged inside the film body 3 to support the film body 3, while the steering cylinder 7 is arranged outside the film body 3 to drive the film body 3 to change direction along the direction of its cylindrical surface at the position where the steering cylinder 7 is arranged, so as to be adapted to the structure of the cover body 2; the support cylinder 9 is correspondingly arranged at the top of the cover body 2 in a portal structure, and the steering cylinder 7 is correspondingly arranged at the bottom of the portal structure; in the projection direction of the conveyor 1, the support cylinder 9 is arranged inside the portal structure, while the steering cylinder 7 is arranged outside the portal structure. In the height direction, the steering cylinder 7 is located below the corresponding support cylinder 9. In this way, the support cylinder 9 is arranged on the upper side and on the side of the film body 3 close to the conveyor 1 to support the film body 3, and the steering cylinder 7 is arranged below the support cylinder 9 and is in contact with the surface of the film body 3 away from the conveyor 1, so as to limit the film body 3 on the outside of the film body 3. In the height direction, the lowest position of the steering cylinder 7 defines the lowest point of the film body 3, and the highest position of the support cylinder 9 defines the highest point of the film body 3; this can form an approximate portal structure for the flexible film body 3, so as to be matched with the structure of the cover body 2, avoid deformation of the film body 3, and ensure that the film body 3 can cover the interval area.

[0037] In an alternative embodiment, it is defined that in the extending direction of the conveyor, the length between two adjacent cover bodies 2 is the interval length; the axial length of the steering cylinder 7 matches the interval length, and the axial length of the support cylinder 9 matches the interval length. That is to say, the steering cylinder 7 and the support cylinder 9 are substantially the same size as the interval area in the extending direction of the conveyor 1. The meaning of substantially the same is that it is exactly the same size as the interval area or slightly smaller than the size of the interval area; thus, the support cylinder 9 and the steering cylinder 7 can form complete support and limitation in the part where the film body 3 covers the interval area, further avoiding deformation of the film body 3.

[0038] In the above-described embodiment, in the width direction, the fixing member 5 is located on the side of the steering cylinder 7 on the same side away from the conveyor 1, and the film cylinder 6 is located on the side of the steering cylinder 7 on the same side away from the conveyor 1. Thus, the film cylinder 6 and the fixing member 5 form a pull on the bottom of the film body 3, and the two steering cylinders 7 are located on the side of the film cylinder 6 and the fixing member 5 on the corresponding side close to the conveyor 1 and limit the film body 3, so as to be able to form a reverse stop on the film body 3 in the pulling direction, thereby making the structure of the film body 3 more stable.

[0039] In some other embodiments, refer to Figure 4, the hood 2 includes an inner plate 24 and an outer plate 25. Specifically, the inner plate 24 and the outer plate 25 can be made of steel plates with a thickness of 2 mm. Of course, metal plates of other models and materials can also be used, and those skilled in the art can choose by themselves; the inner plate 24 and the outer plate 25 are arranged at intervals; in a specific example, the gap between the inner plate 24 and the outer plate 25 is 3 mm, and the outer plate 25 is located on the side of the inner plate 24 away from the conveyor 1; the bottoms of the inner plate 24 and the outer plate 25 can be spot-welded to the bottom plate 8, and the bottom plate 8 can be a steel plate.

[0040] In the extending direction of the conveyor 1, both side edges of the film body 3 are located between the inner plate 24 and the outer plate 25 of the corresponding side sealing hood; specifically, the film body 3 extends beyond the film cylinder 6 in the axial direction of the film cylinder 6, and the part of the film body 3 that extends beyond the film cylinder 6 serves as the side edge. There are side edges on both sides in the axial direction of the film cylinder 6 (the extending direction of the conveyor 1), and the side edges are embedded between the inner plate 24 and the outer plate 25. By sandwiching both sides of the film body 3 between the inner plate 24 and the outer plate 25, the double-layer hood 2 can be set, which can limit and guide both side edges of the film body 3. At the same time, the shape of the film body 3 can be kept consistent with that of the hood 2. At the same time, by overlapping both side edges of the film body 3 with the hood 2, the formation of a gap between the film body 3 and the hood 2 can be avoided.

[0041] By adopting the sealing device of the conveyor 1 in this application, the following advantages can be achieved:

[0042] First, through the cooperation of the hood 2 and the film body 3, to a certain extent, the sealing treatment of the conveyor 1 during the conveying process can be achieved, preventing odors or dust from spreading in the air and polluting the environment and reducing air quality.

[0043] Second, by arranging two support cylinders 9 and two steering cylinders 7, a stable frame structure is formed to maintain the stability of the shape of the film body 3.

[0044] Third, by arranging the film cylinder 6 structure, when the conveyor 1 fails and needs to be maintained, as long as a certain section of the film body 3 is opened, it can be repaired. After the repair is completed, the film is resealed. If the film body 3 is damaged, the new film body 3 is pulled out for sealing operation.

[0045] Fourth, the PVC film body 3 has the advantages of stable properties, not easily being corroded, low price, and low maintenance cost.

[0046] Fifth, during the operation of the conveyor 1, when the dust attached to the surface of the film body 2 reduces the transparency of the film body 2, making it impossible to observe the operation process of the conveyor 1 through the film body 2, the film body 2 can be quickly replaced through the sealing device in this solution, so that the operation state of the conveyor 1 can be observed again through the film body 2.

The description of the above embodiments is only used to help understand the core idea of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
