[0042] The dustproof device 100 for conveyor includes head sealing dustproof device 20, middle part sealing cover and tail sealing dustproof device 30, specifically, the first sealing cavity formed by hopper body 4 and head shield 3 of head sealing dustproof device 20 effectively seals the head of conveyor body 200, reduces the dust problem caused by the loose combination of the front section of material guide groove 300 and the head of belt conveyor body 200, and the dust collection port 31 at the top of head shield 3 can be connected to an external dust removal system, further collecting and filtering the possible leakage of dust, improving the dustproof effect, the second sealing cavity surrounded by tail shield 5 and dustproof baffle 6 of tail sealing dustproof device 30 effectively seals the tail of conveyor body 200, preventing dust from being generated when discharging materials, the dustproof cavity formed by the two dustproof racks 10 of middle part sealing cover, cover plate 400 and the outer side wall of conveyor body 200 realizes the sealing of the middle part of conveyor body 200, and the dustproof cavity is communicated with the sealing cavities of the head and the tail, forming a continuous sealing system. The dustproof structure of the utility model considers the sealing requirements of different parts of conveyor body 200, not only solves the dust problem, but also improves the material recovery efficiency and the reliability of equipment operation.

[0043] In an embodiment, the dustproof frame 10 comprises a dustproof side part 1 and a dustproof plate 2, the dustproof side part 1 is arranged beside the conveyor body 200, one end of the dustproof side part 1 is supported on the belt gallery, and the other end extends along the height direction of the conveyor body 200; the dustproof side part 1 also extends along the conveying direction of the conveyor body 200; the two ends of the dustproof plate 2 are respectively sealingly connected with the dustproof side part 1 and the cover plate 400, and the dustproof plate 2, the dustproof side part 1 and the outer side wall of the conveyor body 200 together enclose a dustproof cavity. When the material moves on the conveying belt, part of the material or dust may be spilled from the guide chute 300 due to improper sealing. Since the dustproof cavity exists, the dust is limited in the dustproof cavity and cannot be directly dispersed into the surrounding environment, which greatly optimizes the sealing performance of the guide chute 300, thereby protecting the health of workers and maintaining the cleanliness of the production environment, and solving the dust problem of the conveyor body 200 when conveying dry powder materials.

[0044] It should be noted that the dustproof frame 10 can be a single whole or a complete dustproof frame 10 formed by sequentially connecting multiple dustproof frame 10 units. When one dustproof frame 10 is arranged, the dustproof frame 10 can be arranged at a key position, such as a section where dust is most likely to be generated or a conveying belt corner, to reduce dust at this position. When multiple dustproof frames 10 are arranged, the dustproof frame 10 units can be assembled according to specific production needs and environmental conditions. For example, in an embodiment, the dustproof structure of the conveyor body 200 comprises multiple dustproof frames 10, the dustproof side parts 1 of the multiple dustproof frames 10 are sequentially connected along the conveying direction of the conveyor body 200, and the dustproof plates 2 of the multiple dustproof frames 10 are sequentially connected along the conveying direction of the conveyor body 200. In this way, the dustproof side part 1 of each dustproof frame 10 is connected with the dustproof side parts 1 of the previous and next dustproof frames 10, forming a continuous side protection line, and similarly, the dustproof plates 2 of each dustproof frame 10 are also sequentially connected, forming a continuous top protection surface. The sequential connection of the dustproof side part 1 and the dustproof plate 2, together with the outer side wall of the conveyor body 200, encloses a closed dustproof cavity extending along the conveying direction. When the material moves on the conveying belt, the dust is limited in the dustproof cavity and cannot leak to the external environment. In this way, the sequential connection of the multiple dustproof frames 10 ensures continuous protection during the entire conveying process, and each dustproof frame 10 can be used as a module for easy installation, maintenance and replacement. In addition, the number of dustproof frames 10 can be flexibly increased or decreased according to the length of the conveyor body 200 and the dust control needs, without affecting the normal work of other parts.

[0045] In an embodiment, the dustproof side part 1 is provided with a plurality of installation grooves 13 communicating with the dustproof cavity on the side away from the conveyor body 200, and the plurality of installation grooves 13 are arranged along the height direction of the conveyor body 200 and / or the conveying direction of the conveyor body 200; the dustproof frame 10 further comprises a plurality of dustproof buckle plates 14, and the plurality of dustproof buckle plates 14 are arranged one by one corresponding to the plurality of installation grooves 13, and the dustproof buckle plate 14 is inserted into the installation groove 13. The corresponding insertion design of the dustproof buckle plate 14 and the installation groove 13 ensures the sealing performance of the dustproof cavity, effectively prevents dust leakage, and because the dustproof buckle plate 14 can be flexibly inserted and taken out of the installation groove 13, the maintenance personnel can easily enter the dustproof cavity for maintenance without disassembling the entire dustproof side part 1. It should be noted that a sealing material such as a rubber pad or sealant can be arranged between the dustproof buckle plate 14 and the installation groove 13 to ensure the sealing performance, and the dustproof buckle plate 14 should be made of wear-resistant and corrosion-resistant materials to adapt to harsh production environments.

[0046] In an embodiment, the dustproof side part 1 comprises a plurality of first support rods 11 and a plurality of second support rods 12; the plurality of first support rods 11 are arranged along the height direction of the conveyor body 200, and each first support rod 11 extends along the conveying direction of the conveyor body 200; the plurality of second support rods 12 are arranged along the conveying direction of the conveyor body 200, and each second support rod 12 extends along the height direction of the conveyor body 200; the dustproof plate 2 is sealingly connected to the first support rod 11 close to the cover plate 400; wherein the plurality of first support rods 11 and the plurality of second support rods 12 are assembled together to form the plurality of installation grooves 13. The first support rod 11 and the second support rod 12 are cooperatively installed to form the support framework of the dustproof side part 1, and therefore the first support rod 11 and the second support rod 12 need to provide good structural stability to withstand the vibration and impact during the material conveying process, and therefore bolts, welding or other fixing methods can be used. In other embodiments, the dustproof side part 1 can also not adopt a frame structure, but adopt a plate structure, and the entire dustproof side part 1 is composed of one or more plate-shaped materials, which can be metal plates, plastic plates, glass steel or other wear-resistant and corrosion-resistant materials. Unlike the frame structure, the plate structure does not rely on support rods to maintain shape and strength, but relies on the structural strength of the plate itself. The plate structure simplifies the structure of the dustproof side part 1, reduces the number of parts, and the overall or spliced plate structure can better fit the side of the conveyor body 200, reducing dust leakage.

[0047] In an embodiment, the dustproof flap 14 comprises a plate body 141 and a reinforcing edge 142, the plate body 141 is installed in cooperation with the installation groove 13, and the reinforcing edge 142 is arranged on one side of the plate body 141 close to the conveyor body 200. The plate body 141 is the main part of the dustproof flap 14, which is used to shield and prevent dust, sundries and dust from coming out of the dustproof cavity. The plate body 141 is usually made of metal (such as steel plate), plastic or other wear-resistant materials. The reinforcing edge 142 is located at the edge of the plate body 141, which provides additional support and strength. The reinforcing edge 142 can be designed as a fold, a rolled edge or an additional reinforcing strip, which not only enhances the structural stability of the plate body 141, but also facilitates the installation of the plate body 141 in the installation groove 13, so as to prevent the dustproof flap 14 from being deformed or falling off during use due to impact or vibration.

[0048] In an embodiment, the plate body 141 is provided with an observation window 143. In this way, the operating personnel or maintenance personnel can directly observe the working state inside the conveyor, and perform monitoring and troubleshooting. The observation window 143 can be made of transparent materials such as acrylic plate, polycarbonate or tempered glass, which have sufficient strength and transparency.

[0049] In an embodiment, the dustproof device 100 for the conveyor further comprises a p-type scraper cleaner 7 arranged at the lower part of the head drum of the conveyor body 200 and corresponding to the return section of the conveyor belt of the conveyor body 200, which is used to scrape off the adhered materials on the head drum belt. The structure of the p-type scraper cleaner is usually simple, which is convenient for installation and maintenance, and the cost is relatively low. The p-type scraper cleaner 7 helps to keep the belt clean, avoiding the accumulation of materials affecting the operation of the belt and the efficiency of material conveying. In another embodiment, the dustproof device 100 for the conveyor further comprises an H-type scraper cleaner arranged at the lower part of the head drum of the conveyor body 200 and corresponding to the return section of the conveyor belt of the conveyor body 200. The scraper of the H-type scraper cleaner is used to scrape off the adhered materials on the head drum belt of the conveyor belt of the conveyor body. The structure of the H-type scraper cleaner is usually more solid, which can withstand greater force and is more suitable for cleaning more stubborn adhered materials. Of course, the p-type scraper cleaner 7 and the H-type scraper cleaner can also be arranged at the same time. The two types of scraper cleaners work at the same time, which can more efficiently clean the adhered materials on the belt, reduce downtime and improve production efficiency.

[0050] In an embodiment, the dustproof device 100 for the conveyor further comprises a brush sweeper 9 arranged below the conveying belt of the conveyor body 200 and corresponding to the arrangement of the return section of the conveying belt of the conveyor body 200, for removing the materials adhered to the middle section of the conveying belt of the conveyor body. The softness and density of the brush can effectively remove fine materials and materials with strong adhesion, and the brush can adapt to the fluctuation and shape change of the conveying belt, providing uniform cleaning force. In combination with the P-shaped scraper sweeper and the H-shaped scraper sweeper, a multi-level cleaning system can be formed to improve the cleaning effect.

[0051] In an embodiment, the dustproof baffle 6 is arranged downwardly from the tail section of the conveyor body 200 to the head section of the conveyor body 200, and the dustproof baffle 6 is provided with a dust removal door 61.

[0052] In an embodiment, the top of the tail cover 5 is provided with a second inspection door 51. The second inspection door 51 allows the operator to conveniently check the internal condition of the tail section of the conveyor body 200, including but not limited to checking the state of the bearing, the driving device or other key components.

[0053] The dustproof baffle 6 is arranged downwardly from the tail section of the conveyor body 200 to the head section of the conveyor body 200, and the dustproof baffle 6 is provided with a dust removal door 61.
