Description

Technical Field

[0001] This application relates to the field of conveying machinery, and more particularly to a dust collection device for belt conveyors. Background Technology

[0002] Conveyor belts are devices used for material handling and are widely used in various industrial fields. They are mainly made of rubber, fiber, or plastic composites with fabrics. Driven by a motor, the belt moves to achieve continuous and uniform material transport. Some conveyor belts transport powdery materials, which can lead to material scattering and waste. This scattered material can be inhaled by operators and pose a health hazard. Excessive material scattering also reduces transport efficiency. Therefore, conveyor belts transporting powdery materials are equipped with dust collection devices.

[0003] The dust collection and recovery device for belt conveyors in related technologies mainly includes a conveyor belt, a dust cover installed on the conveyor belt, a dust cover including a top plate and two side plates, the dust cover being set along the belt conveying direction, a dust collection bucket on the dust cover, a dust collection pipe connected to the dust collection bucket, and a dust collection pipe connected to an external bag filter dust collector to absorb and treat the material raised during the belt conveying process. The discharge port of the bag filter dust collector is connected to the dust cover, and the dust material treated by the bag filter dust collector can fall back onto the belt, realizing the recycling and utilization of the material.

[0004] Regarding the aforementioned technologies, due to the structural characteristics of the conveyor belt, it is supported by rollers and rotates under the drive of a motor. Because the conveyor belt needs to maintain motion, it cannot fit tightly against the dust cover, resulting in a large gap between them. This poor sealing of the dust cover allows powder to escape from the gap between the dust cover and the conveyor belt, reducing the amount of powder ultimately collected by the dust collection bin and decreasing the efficiency of material recovery and utilization. Utility Model Content

[0005] In order to improve the dust collection efficiency of belt conveyor dust collection devices, which suffer from poor dust collection efficiency due to the gap between the powder conveyor belt and the dust cover, this application provides a dust collection device for belt conveyors.

[0006] This application provides a dust collection device for belt conveyors, which adopts the following technical solution:

[0007] A dustproof recycling device for belt conveyor includes a conveyor belt, a dustproof cover disposed along the conveyor belt, and a recycling component communicating with the dustproof cover. The dustproof cover is provided with a dustproof component, which includes a dustproof pad for preventing dust from entering the gap between the dustproof cover and the conveyor belt.

[0008] By adopting the above technical solution, the conveyor belt slides relative to the dust cover during its movement, resulting in a large gap between the dust cover and the conveyor belt. A dustproof component, including a dustproof pad, is installed on the dust cover. The dustproof pad prevents powder inside the dust cover from escaping through the gap between the dust cover and the conveyor belt, thus improving the problem of low dust prevention and recovery efficiency of the dust collection device for belt conveyors due to the large gap between the dust cover and the conveyor belt.

[0009] Optionally, the dustproof assembly further includes bolts, through which the dustproof pad is fixedly connected to the dustproof cover.

[0010] By adopting the above technical solution, fixing the dustproof mat with bolts makes it easier to replace the dustproof mat compared to directly fixing it to the dust cover. Since the dustproof mat and the transmission belt come into contact and friction occurs, the dustproof mat will inevitably suffer some damage over time. Fixing the dustproof mat to the dust cover with bolts improves the problem of the dust cover being difficult to replace after damage.

[0011] Optionally, a pressure plate is provided on the side of the dustproof pad away from the dustproof cover, and the pressure plate presses the dustproof pad onto the dustproof cover by bolts.

[0012] By adopting the above technical solution, the dustproof pad, fixed with bolts, fits tightly against the dustproof cover at the bolt fixing points. At points not fixed with bolts, gaps exist between the dustproof pad and the dustproof cover, allowing powder from the conveyor belt to escape. By placing a pressure plate between the dustproof pad and the bolts, ensuring a tight fit, and finally securing the pressure plate and dustproof pad to the dustproof cover with bolts, a tight fit between the dustproof pad and the dustproof cover is achieved. This ensures a tight fit even when the dustproof pad is replaceable.

[0013] Optionally, the dustproof pad is disposed on the outer side wall of the dust cover, and the pressure plate is provided with a support plate bent toward the dust cover near the edge of the transmission belt, and the dustproof pad is attached to the upper surface of the transmission belt by the support of the support plate.

[0014] By employing the above technical solution, the conveyor belt and the dust cover slide relative to each other, and the dust cover may bend away from the conveyor belt. When the dust cover bends away from the conveyor belt, a large gap is created between the dust cover and the conveyor belt, and the powder conveyed on the conveyor belt will spill out of the dust cover through the gap. By setting a support plate on the pressure plate, the support plate bends towards one side of the dust cover, which to a certain extent guides and supports the bending direction of the dust cover, thereby improving the dustproof effect of the dust cover.

[0015] Optionally, a protective sheet is provided between the pressure plate and the dustproof pad, and there is a gap between the bottom edge of the protective sheet and the transmission belt.

[0016] By adopting the above technical solution, the dustproof pad and the conveyor belt will generate a certain degree of friction when they slide in contact. This friction may cause the dustproof pad and the bolts fixing it to tear to some extent, eventually resulting in gaps outside the fixing bolts and reducing the dustproof effect of the dustproof assembly. By setting a protective plate between the pressure plate and the dustproof pad, because there is a certain gap between the bottom edge of the protective plate and the conveyor belt, the bottom edge of the protective plate will not rub against the conveyor belt. When a gap appears on the dustproof pad, the protective plate will compensate for the broken gap, ensuring the dustproof effect of the dustproof assembly.

[0017] Optionally, multiple protective plates are provided, and each protective plate corresponds to one bolt.

[0018] By adopting the above technical solution, protective plates can be installed at the corresponding positions of the bolts, allowing the protective plates to be replaced individually, saving material for the protective plates, and facilitating maintenance personnel in repairing the protective components.

[0019] Optionally, the dustproof pad includes a dustproof brush and a support portion that supports the dustproof brush. One side of the dustproof brush is fixedly connected to the support portion, and the side of the dustproof brush away from the support portion abuts against the upper surface of the transmission belt.

[0020] By adopting the above technical solution, since the transmission belt will experience a certain degree of wear during use, the upper surface of the transmission belt in contact with the dustproof mat may have protrusions and depressions. By installing a dustproof brush near the edge of the transmission belt on the dustproof mat, the bristles of the dustproof brush are softer and more easily deformable than a solid dustproof mat. This ensures that when the dustproof brush comes into contact with the protrusions and depressions on the upper surface of the transmission belt, the dustproof brush deforms, and the dustproof mat and the transmission belt can still maintain a good dustproof effect.

[0021] Optionally, the top of the dust cover has an observation port along the direction of the transmission belt, and the observation port is covered with a baffle.

[0022] By adopting the above technical solution, an observation port is opened on the top of the dust cover, and a baffle is provided on the observation port. The operator can lift the baffle and observe the material transportation on the conveyor belt through the observation port. When the material transportation on the conveyor belt malfunctions, the operator can find the source of the malfunction and carry out maintenance through the observation port.

[0023] Optionally, a sealing strip is provided around the observation port, and the baffle is fitted with the sealing strip.

[0024] By adopting the above technical solution, the observation port at the top of the dust cover is equipped with a baffle, and there is a certain gap between the baffle and the observation port. A sealing strip is installed around the observation port. When the baffle is placed on the observation port, the baffle and the sealing strip fit tightly together. This ensures that the entire belt conveyor dust collection device still has a good dust collection effect when the baffle is placed on the observation port.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The dust collection device for belt conveyors of this application improves the dust prevention and collection effect of the dust collection device by setting a dust prevention component on the dust cover. The dust prevention component includes a dust prevention pad set between the conveyor belt and the dust cover. The dust prevention pad plays a certain role in blocking the gap between the conveyor belt and the dust cover. Compared with a dust cover without a dust prevention component, the dust collection device for belt conveyors improves the dust prevention and collection effect.

[0027] 2. The dust collection device for belt conveyors of this application fixes the dust pad with bolts and presses the dust pad with a pressure plate, which ensures the dust protection effect of the dust pad on the dust cover while facilitating the replacement of the dust pad.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] Reference Figure 1 and Figure 2This application discloses a dust collection device for belt conveyors, including a conveyor belt 1, a dust cover 2 disposed along the conveying direction of the conveyor belt 1, and a collection component 4 communicating with the dust cover 2. Supports 5 are provided on both sides of the dust cover 2, supporting the dust cover 2. The dust cover 2 is mounted above the conveyor belt 1 by the supports 5 on both sides of the dust cover 2. The bottom edge of the dust cover 2 does not contact the conveyor belt 1. A dust-proof component 3 is disposed on the dust cover 2.

[0035] The recycling component 4 includes a dust collection bin 41 located on top of the dust cover 2 and connected to the dust cover 2. A suction pipe 42 is connected to the end of the dust collection bin 41 furthest from the dust cover 2. The suction pipe 42 is connected to a bag filter 43, which is located at the beginning of the conveyor belt 1. A discharge chute 431 is located at the bottom of the bag filter 43, and the discharge chute 431 is connected to a discharge port 44 on the top of the dust cover 2. An observation port 21 is located on the top of the dust cover 2 along the direction of the conveyor belt 1. A sealing strip 211 is provided around the observation port 21, and a baffle 22 is provided on top of the observation port 21, fitting snugly against the sealing strip 211 when the baffle 22 is placed over the observation port 21.

[0036] Reference Figure 2 , Figure 3 and Figure 4 The dustproof assembly 3 includes a dustproof pad 31 and bolts 35. The dustproof pad 31 prevents dust from entering the gap between the dustproof cover 2 and the conveyor belt 1. The bolts 35 fix the dustproof pad 31 to the dustproof cover 2. One side of the dustproof pad 31 is in contact with the bottom of the outer wall of the dustproof cover 2. A pressure plate 32 is provided on the side of the dustproof pad 31 away from the dustproof cover 2. The pressure plate 32 presses the dustproof pad 31 tightly onto the dustproof cover 2 by the bolts 35. A support plate 33 is provided on the pressure plate 32 near the edge of the conveyor belt 1, bending towards one side of the dustproof cover 2. The dustproof pad 31 is bent in the direction of the bending of the support plate 33 under the support of the support plate 33. With the pressure plate 32 and bolts 35 in place, the pressure plate 32 presses the entire dustproof pad 31 firmly, and the bolts 35 then secure the pressure plate 32 pressed onto the dustproof pad 31. This ensures that there are no gaps between the dust cover 2 and the dustproof pad 31 where there are no bolts 35 fixing them, further improving the dustproof effect of the dustproof pad 31 while allowing for easy replacement. The support plate 33 guides the bending direction of the dustproof pad 31, ensuring that the dustproof pad 31 does not bend away from the dust cover 2.

[0037] The dustproof pad 31 includes a dustproof brush 311 and a support portion 312 that supports the dustproof brush 311. The support portion 312 is attached to the bottom edge of the outer wall of the dust cover 2. One side of the dustproof brush 311 is fixedly connected to the support portion 312, and the side of the dustproof brush 311 away from the support portion 312 abuts against the upper surface of the conveyor belt 1. In this embodiment, the dustproof pad 31 is a rubber dustproof pad 31. It should be noted that the dustproof pad 31 can also be made of other flexible materials, not limited to rubber. During the transmission process of the conveyor belt 1, because the dustproof brush 311 has dense bristles, even if there are protrusions and depressions on the upper surface of the conveyor belt 1, the dustproof brush 311 deforms under the force of the conveyor belt 1 and can still abut against the upper surface of the conveyor belt 1, thus improving the dustproof effect of the dustproof pad 31 on the gap between the dust cover 2 and the conveyor belt 1.

[0038] A protective plate 34 is also provided between the pressure plate 32 and the dustproof pad 31. Multiple protective plates 34 are provided, each corresponding to a bolt 35. There is a certain gap between the bottom edge of the protective plate 34 and the transmission belt 1. During belt conveying, the dustproof pad 31 and the transmission belt 1 come into contact with each other. Under the action of friction, the dustproof pad 31 and the bolt 35 experience a certain degree of tearing, which can easily lead to damage to the dustproof pad 31. Because the edge of the protective plate 34 near the transmission belt 1 does not come into contact with the transmission belt 1, the protective plate 34 is not subject to friction, and therefore, there is no tearing between the protective plate 34 and the bolt 35. The protective plate 34 fills the gaps in any damage to the dustproof pad 31, ensuring the dustproof effect of the dustproof pad 31.

[0039] During the installation of the entire dustproof assembly 3, first, the support part 312 of the dustproof pad 31 is attached to the bottom edge of the outer wall of the dust cover 2. Then, protective plates 34 are used to protect the positions where bolts 35 are needed for fixing. The pressure plate 32 is used to press the dustproof pad 31 and the protective plate 34 together. Finally, bolts 35 are used to pass through the pressure plate 32 and the protective plate 34 to fix the dustproof pad 31 to the dust cover 2. While ensuring that the dustproof pad 31 is removable, it provides good dustproof performance.

[0040] The implementation principle of the dustproof recovery device for belt conveyors in this application embodiment is as follows: Powder is transported on the conveyor belt 1. During the feeding and transportation process, powder may be stirred up. A dust cover 2 is installed on the conveyor belt 1, and a dustproof component 3 is further installed on the dust cover 2. The dustproof component 3 prevents dust from entering the gap between the dust cover 2 and the conveyor belt 1. Under the action of the dust cover 2 and the dustproof component 3, the stirred-up powder will not spill into the entire operating environment. The powder in the dust cover 2 is sucked into the suction pipe 42 through the suction bucket 41, and enters the bag filter 43 along the suction pipe 42. After being processed in the bag filter 43, it is discharged onto the conveyor belt 1 through the discharge chute 431 and the discharge port 44. The dustproof component 3 improves the dustproof effect of the dust cover 2, thereby further improving the dustproof and recovery rate of the dustproof recovery device for belt conveyors. During the operation of the dust collection device for belt conveyor, the operator can also observe the powder transportation on the conveyor belt 1 through the observation port 21. If a fault occurs on the conveyor belt 1, the observation port 21 can help the operator confirm the source of the fault.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
