Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor technology, specifically a conveyor with a dustproof structure. Background Technology
[0002] A belt conveyor is a type of conveyor that uses a conveyor belt to continuously transport materials. It is mainly used to transport materials from the feeding point to the unloading point on a fixed conveyor line. It is widely used in various fields. Since some materials generate a lot of dust during the conveying process, the dustproof function of the conveyor is particularly important to avoid respiratory damage to workers.
[0003] An investigation revealed that a Chinese utility model patent (publication number: CN222041636U) discloses a dustproof conveyor, comprising: a dust cover; a fan facing the conveyor body is installed on one of the left and right sides of the dust cover; and a ventilation duct is connected to the fan on the other side of the dust cover, with a dust collection plate installed in the ventilation duct. The dust cover encloses the conveyor body from the left, right, and top sides, effectively preventing large amounts of dust generated during the conveying of granular materials from spreading into the surrounding environment, thus avoiding impact on the respiratory system and health of nearby workers. After each conveying operation, the fan blows air onto the conveyor body, blowing dust from the conveyor body into the ventilation duct, where it is then intercepted and collected by the dust collection plate, making it difficult for dust to enter the interior of the conveyor body and minimizing wear and malfunctions caused by dust ingress.
[0004] Although the aforementioned patent achieves dust prevention through the cooperation of fans, ventilation ducts, and dust covers, its use still has certain limitations. Because its inlet and outlet ends are still open structures, some airflow will still be blown towards the inlet and outlet ends during operation, resulting in dust dispersion at the inlet and outlet ends. This reduces the dust prevention effect of the device, not only reducing the protection of the equipment but also easily causing respiratory damage to nearby workers.
[0005] Therefore, this utility model provides a conveyor with a dustproof structure to solve the above problems. Utility Model Content

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figure 1-5 As shown, this utility model provides a conveyor with a dustproof structure, including a belt conveyor 1, with frames 11 at both ends of the belt conveyor 1; a dust cover 2, which covers the top of the frames 11, and the dust cover 2 has a baffle 3, a metal water pipe 4, a dust suction hood 5, a sealing plate 6, a first guide plate 7, and a second guide plate 8 inside; the baffle 3, the sealing plate 6, the first guide plate 7, and the second guide plate 8 are located at the feeding end of the dust cover 2, the metal water pipe 4 is located at the discharging end of the dust cover 2, and the dust suction hood 5 is located between the feeding end and the discharging end of the dust cover 2. Through the cooperation of this structure, the dustproof effect of the device during the material discharge and conveying process can be greatly improved, effectively preventing dust dispersion.
[0031] The dust cover 2 includes a feeding cover 21 and a discharging cover 23. A feeding pipe 24 is integrally provided on the top of the feeding cover 21. Several sets of connecting covers 22 are connected between the feeding cover 21 and the discharging cover 23. The number of connecting covers 22 can be selected according to the length of the frame 11, which greatly improves its adaptability and flexibility, and makes the dust cover 2 effectively adaptable to frame 11 of different lengths for dust protection.
[0032] An insertion slot is provided on the upper part of the feeding hood 21, and baffles 3 are inserted into the upper and lower parts of the insertion slot. Two sets of guide seats 25 are fixedly connected to the outer wall of the dust cover 2 corresponding to the insertion slot, and positioning pins 31 are inserted into the inside of the guide seats 25. Adjustment holes are evenly provided on the baffles 3, and the diameter of the adjustment holes is equal to the diameter of the positioning pins 31. The positioning pins 31 pass through the guide seats 25 and are inserted into the adjustment holes of the baffles 3. The baffles 3 are mainly used to control the discharge and prevent excessive discharge at one time. The positioning pins 31 are used to position the insertion of the baffles 3 at different positions of the adjustment holes, so that the insertion height of the baffles 3 can be flexibly adjusted, and the insertion height of the baffles 3 also changes with the diameter of the material.
[0033] The metal water pipe 4 extends into the interior of the discharge hood 23, and three sets of atomizing nozzles 41 are evenly distributed on the outer wall of the metal water pipe 4 inside the discharge hood 23. Through the atomizing spray of the atomizing nozzles 41, the falling material can be sprayed, thereby further achieving dust prevention treatment for material conveying and avoiding the dispersion of a large amount of dust during the discharge process. The end of the metal water pipe 4 is connected to an external high-pressure water supply pipe for water supply.
[0034] The dust hood 5 is connected to the center of the connecting cover 22, and a three-way pipe 51 is connected to the top of the dust hood 5. Adjacent three-way pipes 51 are connected through a flexible hose 52. The outside of one end of the three-way pipe 51 is connected to a dust collector and a fan through a conveying pipe 53. The outside of the other end of the three-way pipe 51 is sealed with an end cap. The connection between the conveying pipe 53 and the external dust collector and fan allows the conveying pipe 53, together with the three-way pipe 51, the flexible hose 52 and the dust hood 5, to continuously adsorb dust inside the connecting cover 22, thereby reducing the dispersion of dust during material transportation. With the setting of the external dust collector, the equipment can achieve continuous dust removal. The dispersed dust can be adsorbed and purified by the dust collector.
[0035] The inner wall of the feed pipe 24 is provided with a support shaft adapted to the rotation of the sealing plate 6, and the inner wall of the feed pipe 24 is fixedly connected with an abutment frame 61 for the sealing plate 6 to abut and limit its movement. The first guide plate 7 and the second guide plate 8 are both fixedly connected to the inner wall of the feed hood 21, and the first guide plate 7 and the second guide plate 8 are both distributed in an inclined manner. The first guide plate 7 slides against the outer wall of the baffle 3 at its highest point. The abutment frame 61 is mainly used for the vertical abutment of the sealing plate 6 to ensure that the sealing plate 6 maintains a good sealing effect in its natural vertical state. When material is added, the weight of the material causes the sealing plate 6 to rotate, thereby causing the material to fall into the interior of the feed hood 21. At the same time, the material is prevented from falling directly onto the frame 11 by the double buffering and guiding of the first guide plate 7 and the second guide plate 8, thus achieving safety protection for the frame 11.
[0036] Working principle: First, the device is assembled and connected with relevant external auxiliary equipment. Then, material is added through the feed pipe 24. The weight of the material causes the sealing plate 6 to rotate and fall into the inside of the feed hood 21. After being buffered and guided by the first guide plate 7 and the second guide plate 8, the material falls above the frame 11. During the material conveying process, the dust suction hood 5 can adsorb the dust generated inside the connecting hood 22. When the material is discharged through the discharge hood 23, the dust is further reduced by the spray of the atomizing nozzle 41.
[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
