Description

Technical Field

[0001] This application relates to the field of cement production technology, specifically to a dust collection device applied to a long conveyor belt for batching. Background Technology

[0002] The batching station is a critical control point in the cement production process. Through precise control and real-time monitoring of the batching process, operators can adjust the batching plan and parameters in a timely manner according to production conditions, thereby achieving effective control over the entire cement production process. Inevitably, the batching station requires the use of various types of long belt conveyors for raw material transportation. Although the batching station is equipped with integrated dust collection equipment to effectively prevent dust overflow, dust emission still occurs at the long belt conveyors during actual use, affecting the working environment within the batching station. Utility Model Content

[0003] In view of the above problems, this application provides a dust collection device for use at the long conveyor belt of the batching plant, which can effectively solve the dust emission problem at the long conveyor belt in the batching plant and improve the working environment inside the batching plant.

[0004] According to one aspect of the embodiments of this application, a dust collection device for use on a long conveyor belt for batching is provided. The dust collection device for use on a long conveyor belt includes a strip-shaped dust collection hood that covers the top of the belt. Multiple exhaust pipes are provided on the top of the strip-shaped dust collection hood, each exhaust pipe being connected to a corrugated pipe. The other end of each corrugated pipe is connected to a bend, and the multiple bends are connected to a main exhaust pipe. Opposite sides of the strip-shaped dust collection hood extend outwards to form ear plates. Multiple guide rail components are vertically arranged through the ear plates on the side facing away from the strip-shaped dust collection hood. A toothed plate is provided on the side of each guide rail component facing the strip-shaped dust collection hood. The toothed plate includes multiple racks fixed sequentially from top to bottom on the guide rail components. An adjusting motor is fixed to the ear plate. The output shaft of the adjusting motor is coaxially connected to a drive gear, which meshes with the toothed plate. Sliding grooves are formed on opposite sides of the guide rail components. Limiting wheels are rotatably connected to the ear plates, and the outer wall of the limiting wheels is rolledly connected to the inner wall of the sliding grooves.

[0005] In some embodiments, a plurality of guide rail components are symmetrically arranged on both sides of the strip dust collection hood, and a steel plate is connected to the bottom of the plurality of guide rail components. A cast iron block is provided at the connection between the steel plate and the guide rail component.

[0006] In some embodiments, a connecting block is provided on the top of each of the plurality of guide rail components, and two adjacent connecting blocks are connected by reinforcing steel bars. The plurality of reinforcing steel bars enclose a structural frame, and the corrugated pipe is provided to extend upward through the structural frame.

[0007] In some embodiments, a dust cover is provided on the outer periphery of the regulating motor, and the strip dust collection cover is fastened to the outer periphery of the regulating motor and fixed to the ear plate.

[0008] In some embodiments, a mounting base is provided on the top of the ear plate, and a jet gun is detachably mounted on the mounting base. The jet gun is connected to an air supply pipe through a spiral hose.

[0009] In some embodiments, a reinforcing rib is provided at the connection between the ear plate and the strip dust collection hood.

[0010] In some embodiments, a PLC controller is included, which is electrically connected to a plurality of the regulating motors.

[0011] The beneficial effects of this application are as follows: By setting up a strip-shaped dust collection hood, the dust emitted from the long conveyor belt of the batching plant can be absorbed, preventing it from overflowing and affecting the working environment inside the batching station. The strip-shaped dust collection hood also has ear plates, which can cooperate with the guide rail components to assist in raising and lowering the hood. Furthermore, the space at the ear plates can serve as a storage platform for various tools. In this application, by setting a toothed plate on the guide rail components and combining it with an adjusting motor and drive gear, the reaction force between the drive gear and the toothed plate after the adjusting motor starts can drive the strip-shaped dust collection hood to rise or fall as a whole. This allows the strip-shaped dust collection hood to move away from or closer to the long conveyor belt. Furthermore, when the strip-shaped dust collection hood is close to the long conveyor belt, it can enhance the absorption of dust emitted from the conveyor belt. When the strip-shaped dust collection hood is away from the long conveyor belt, operators can easily perform sampling and maintenance operations on the long conveyor belt.

[0019] The embodiments of the technical solution of this application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of this application, and are therefore merely examples and should not be used to limit the scope of protection of this application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and the foregoing description of the accompanying drawings are intended to cover non-exclusive inclusion.

[0020] For details, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the dust collection device applied to the long conveyor belt for batching, provided in an embodiment of this application. Figure 2 This is a partial structural diagram of the device provided in an embodiment of this application. Figure 3This is a partial structural diagram of the strip-shaped dust collection hood and its connection points provided in an embodiment of this application. The dust collection device 100 applied to a long conveyor belt includes a strip-shaped dust collection hood 110 that is fastened to the top of the belt. The strip-shaped dust collection hood 110 is elongated, and its length and width should be set according to the actual dimensions of the long conveyor belt, and should be slightly larger than the length and width of the long conveyor belt to maximize the dust collection effect. Multiple exhaust pipes 111 are provided at the top of the strip-shaped dust collection hood 110. These exhaust pipes 111 are connected at equal intervals along the length of the strip-shaped dust collection hood 110 at its top end to balance the dust collection effect in different areas of the strip-shaped dust collection hood 110. Each exhaust pipe 111 is connected to a corrugated pipe 112, which is retractable, thereby ensuring that the sealing performance of the strip-shaped dust collection hood 110 is not affected by equipment slippage during lifting and lowering. The other end of the corrugated pipe 112 is connected to a bend 113, and multiple bends 113 are connected to a main exhaust duct 114, which can be connected to the existing dust collection device at the top of the batching silo for dust collection. The opposite sides of the strip dust collection hood 110 extend outward to form ear plates 115, and the ear plates 115 and the strip dust collection hood 110 can be an integral structure. Multiple guide rail components 120 are vertically arranged through the side of the ear plate 115 away from the strip dust collection hood 110, and the guide rail components 120 are used to support and limit the strip dust collection hood 110. A toothed plate 121 is provided on the side of the guide rail component 120 facing the strip-shaped dust collection hood 110. The toothed plate 121 includes multiple racks 121a fixed to the guide rail component 120 from top to bottom. The toothed plate 121 can be set separately and connected to the guide rail component 120, or it can be formed into the shape of the toothed plate 121 by cutting on the guide rail component 120. An adjusting motor 130 is fixed at the ear plate 115. The output shaft of the adjusting motor 130 is coaxially connected to a drive gear 131. The drive gear 131 meshes with the toothed plate 121. When the adjusting motor 130 is turned on, it will drive the drive gear 131 to rotate. After the drive gear 131 rotates further, it will rotate on the toothed plate 121 and move upward. Sliding grooves 122 are formed on both sides of the guide rail component 120. A limiting wheel 116 is rotatably connected to the ear plate 115. The outer wall of the limiting wheel 116 is rolled on the inner wall of the sliding groove 122. During the lifting or lowering of the strip dust collection hood 110, the outer circumference of the limiting wheel 116 is always rolled on the inner wall of the sliding groove 122. This reduces the friction between the guide rail component 120 and the ear plate 115 of the strip dust collection hood 110, and limits the strip dust collection hood 110 to ensure that it always moves in the vertical direction during the lifting or lowering process.

[0021] As can be seen from the above, in this embodiment of the application, by setting up a strip dust collection hood 110, the dust emitted from the long conveyor belt of the batching plant can be absorbed, preventing it from overflowing and affecting the working environment inside the batching plant. The strip dust collection hood 110 has ear plates 115. On the one hand, the ear plates 115 can cooperate with the guide rail component 120 to assist in the lifting and lowering of the strip dust collection hood 110. On the other hand, the space at the ear plates 115 can be used as a storage platform to place various tools. In this application, by setting a toothed plate 121 at the guide rail component 120 and matching it with an adjusting motor 130 and a drive gear 131, after the adjusting motor 130 is started, the reaction force between the drive gear 131 and the toothed plate 121 can drive the strip dust collection hood 110 to be raised or lowered as a whole, thereby making the strip dust collection hood 110 move away from or closer to the long belt conveyor. Furthermore, when the strip dust collection hood 110 is close to the long belt conveyor, it can enhance the adsorption of dust emitted from the long belt conveyor. When the strip dust collection hood 110 is away from the long belt conveyor, the operator can easily complete sampling and maintenance operations at the long belt conveyor.

[0022] In some embodiments, multiple guide rail components 120 are symmetrically arranged on both sides of the strip-shaped dust collection cover 110. A steel plate 140 is connected to the bottom of all the guide rail components 120, and a cast iron block 141 is provided at the connection between the steel plate 140 and the guide rail components 120. Through the above-described arrangement, the cast iron block 141 effectively enhances the stability of the bottom of the guide rail components 120, and the steel plate 140 connects the multiple guide rail components 120 into a single unit, enhancing their stability during use.

[0023] In some embodiments, a connecting block 150 is provided on the top of each of the plurality of guide rail components 120, and adjacent connecting blocks 150 are connected by reinforcing steel bars 151. The plurality of reinforcing steel bars 151 enclose a structural frame, and a corrugated pipe 112 is provided to extend upward through the structural frame. In this embodiment, through the above-mentioned arrangement, the tops of the guide rail components 120 are further connected into an integral structure by the connecting blocks 150 and the reinforcing steel bars 151, which can further improve the stability of each guide rail component 120 and the overall structural strength.

[0024] In some embodiments, a dust cover is provided on the outer periphery of the regulating motor 130, and a strip-shaped dust collection cover 110 is fastened to the outer periphery of the regulating motor 130 and fixed to the ear plate 115. In this embodiment, the dust cover is provided to prevent dust from falling on the outer periphery of the regulating motor 130.

[0025] In some embodiments, a mounting base 117 is provided on the top of the ear plate 115, and a jet gun 118 is detachably mounted on the mounting base 117. The jet gun 118 is connected to an air supply pipe 118b through a spiral hose 118a. In this embodiment, with the above configuration, after working for a period of time, the operator can remove the jet gun 118 to blow away the dust from the entire strip dust collection hood 110 and other components such as the dust cover, using the high-pressure airflow introduced through the air supply pipe 118b to blow away the dust from the strip dust collection hood 110 and other components.

[0026] In some embodiments, a reinforcing rib 160 is provided at the connection between the ear plate 115 and the strip dust collection hood 110. In this embodiment, the reinforcing rib 160 increases the connection area between the ear plate 115 and the strip dust collection hood 110, thereby further enhancing the connection strength between the ear plate 115 and the strip dust collection hood 110.

[0027] In some embodiments, a PLC controller is included, which is electrically connected to multiple regulating motors 130. In this embodiment, through the above configuration, the PLC controller can synchronously control the multiple regulating motors 130, ensuring that they start and stop synchronously.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although the foregoing embodiments have provided a detailed description of this application, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
