Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt conveyor technology, and specifically to a dustproof belt conveyor. Background Technology
[0002] In the research of alternative raw materials for solid waste, solid waste such as desks, cabinets, mattresses, and sofas, due to their high wood content and high calorific value, possess the characteristics of being used to prepare alternative fuels. Therefore, the comprehensive treatment and disposal of this type of solid waste is of great significance for resource conservation and environmental protection.
[0003] The treatment of this type of solid waste requires crushing and air separation processes to remove impurities from the crushed waste wood raw materials. Transfer equipment, such as belt conveyors, is needed between crushing and air separation. Due to the high content of solid waste and wood materials involved, a large amount of dust is generated in the workshop during the belt conveyor transfer process, which is not conducive to the protection of the workshop environment and also affects the health of on-site workers.
[0004] Therefore, this utility model proposes a dustproof belt conveyor. By setting a sealing cover, it effectively avoids the spread of dust and ensures the cleanliness of the working environment. At the same time, it opens an observation window, which, while sealing the belt conveyor, does not hinder the observation of the material conveying status, such as belt misalignment, material accumulation and other abnormal conditions. This has positive significance for workshop environmental protection and stable equipment operation. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.
[0020] Embodiments of this utility model:
[0021] like Figure 1-4 As shown, in this embodiment, a sealing cover 2 is provided on the belt conveyor body 1. The sealing cover 2 includes a housing 21 and a cover plate 22 is detachably provided on the housing 21. In this embodiment, the housing 21 and the cover plate 22 are detachably connected by a buckle.
[0022] In this embodiment, a housing 21 and a cover plate 22 are provided on the inlet side, conveying section, and outlet side of the belt conveyor body 1, respectively, namely a first housing 211, a second housing 212, and a third housing 213, and a first cover plate 221, a second cover plate 222, and a third cover plate 223. A feed inlet 2211 is provided on the first cover plate 221 on the inlet side, and a discharge outlet is provided below the third housing 213 on the outlet side. In this embodiment, the feed inlet 2211 is matched with the crusher outlet, and a flexible canvas connection is used between the feed inlet 2211 and the crusher outlet; the discharge outlet is matched with the inlet of the air flotation machine, and a rigid plate sealing connection or a flexible canvas connection is used between the discharge outlet and the inlet of the air separator.
[0023] An observation window 3 is provided on one side of the first housing 211, the second housing 212, and the third housing 213. The observation window 3 includes a viewing window 31 and an air inlet 32 is provided below the viewing window 31. A guide groove 33 parallel to the viewing window 31 is provided at the air inlet 32 of the first housing 211, the second housing 212, and the third housing 213 so that the incoming air flows through the surface of the inner wall of the viewing window 31.
[0024] An exhaust port 2231 is provided above the third cover plate 223. The exhaust port 2231 is connected to the primary dust removal device 4. The primary dust removal device 4 is connected to the exhaust pipe 5 above. The primary dust removal device 4 includes a pipe body 41. A filter screen 42 is provided inside the pipe body 41. An ash outlet 43 is provided on one side below the filter screen 42. A dust collection plate 44 is inclined upward at the lowest point of the ash outlet 43. An air outlet channel is formed between the side of the dust collection plate 44 away from the ash outlet 43 and the inner side wall of the pipe body 41. The ash outlet 43 is detachably connected to the ash collection bottle 45. In this embodiment, the ash collection bottle 45 is made of transparent glass. The ash outlet 43 and the ash collection bottle 45 are detachably connected by threads. In other embodiments of this utility model, the ash outlet 43 and the ash collection bottle 45 can also be detachably connected by tenon and mortise, flange or other means.
[0025] The principle of this utility model is as follows:
[0026] During the use of this utility model, the waste wood raw materials after being crushed by the crusher are discharged through the crusher outlet. During the process, the soft connecting canvas between the crusher outlet and the feed inlet 2211 of the belt conveyor body 1 can effectively prevent dust.
[0027] After the waste wood raw materials enter the belt conveyor body 1, the sealing cover 2 on the belt conveyor body 1 can effectively prevent dust. In addition, the conveying status can be observed through the observation window 3 on the sealing cover 2. When an abnormality occurs, the cover can be opened by the buckle, and manual intervention can be carried out in a timely and effective manner. In addition, due to the setting of the air inlet and the guide groove 33, the air blows through the inner side of the window 31, which can effectively prevent dust accumulation on the inner side of the window 31, effectively ensuring the long-term cleanliness of the window 31, reducing the frequency of cleaning and workload, and making it more convenient to use. After being conveyed, the crushed waste wood raw materials are sent to the air separator for further impurity removal.
[0028] The dust extracted from the belt conveyor body 1 is processed after being drawn out through the exhaust pipe 5, such as by the dust removal equipment in the factory area (cyclone dust collector, etc.). Before that, the dust is removed by the primary dust removal device 4, which can effectively reduce the processing load at the downstream end. During the operation of the belt conveyor body 1, the dust-laden air passes through the filter screen 42, and some dust is filtered out and accumulated below the filter screen 42. Due to mechanical vibration during the operation of the equipment, the dust will be shaken off after accumulating to a certain amount and collected by the dust collection plate 44 into the dust collection bottle 45. On-site operators can clean it regularly.
