Abstract
Description
Technical Field
[0001] This utility model relates to the field of slag transfer and dust removal technology, specifically to a slag transfer and dust collection system. Background Technology
[0002] During the electrolytic aluminum smelting process, the medium-frequency furnace used will generate hazardous waste such as slag and iron slag. These wastes are usually transported by cart to the slag transfer area for collection and storage. A week later, they are shoveled onto semi-trailers by a loader and transported away. The slag transfer area is set up in the open space of the workshop and is planned with storage, loading and unloading areas.
[0003] During the transfer of hazardous waste, the waste is completely exposed. There is a small amount of dust during unloading and a lot of dust during loading, especially when the waste falls into the truck bed, where even more dust is emitted from above. This cannot meet the requirements of environmentally friendly production and is extremely detrimental to the working environment of employees. Furthermore, the dust can cause employees to develop pneumoconiosis. Therefore, the dust treatment of the above-mentioned hazardous waste is an urgent issue to be addressed. Utility Model Content

[0007] The main dust collector has a longitudinal section in the shape of a "7". Side dust collectors are rotatably provided on both sides of the main dust collector. An angle hydraulic cylinder is provided between the side dust collector and the main dust collector. The cylinder body of the angle hydraulic cylinder is hinged to the main dust collector, and the telescopic end of the angle hydraulic cylinder is hinged to the side dust collector.
[0008] It also includes a dust collector, the air inlet of which is connected to the main dust collector hood via a flexible hose, and the main dust collector hood is connected to the side auxiliary dust collector hood via a corrugated pipe;
[0009] It also includes a controller, with two position sensors for positioning the semi-trailer in the lower half of the bracket, and a position sensor for positioning the height of the truck bed in the bottom of the main dust hood. The signal output terminal of the position sensor is connected to the signal input terminal of the controller, and the controller is electrically connected to the dust collector and the lifting device respectively.

[0018] 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.
[0019] like Figure 1 , Figure 2 , Figure 3As shown, a slag transfer and dust collection system includes a transfer area 2 enclosed by a fence 1. The fence 1 on different sides of the transfer area 2 is provided with an inlet 3 and an outlet 4. When vehicles enter and exit using the inlet 3 and outlet 4, they do not interfere with each other. Due to the fence 1, when unloading and loading in the transfer area 2, part of the dust raised is blocked by the fence 1 and falls back into the transfer area 2, effectively preventing some dust from overflowing.
[0020] A loading area 5, located away from the vehicle entrance 3 and exit 4, is marked on the ground inside the transfer area 2. A support 6 is provided on one side of the loading area 5, and a lifting device 7 is provided on the top of the support 6. The fixed end of the lifting device 7 is fixed to the support 6, and the telescopic end of the lifting device 7 is fixed to the main dust hood 8 placed above the loading area 5. The lifting device 7 is a linear motor, electric push rod, hydraulic cylinder, or pneumatic cylinder. In this embodiment, the lifting device 7 is selected as a hydraulic cylinder. When the semi-trailer is parked in the loading area 5, the lifting device 7 drives the main dust hood 8 to descend to one side above the semi-trailer's cargo bed. The lifting device 7 can raise the main dust hood 8 above the cargo bed without interfering with the semi-trailer's entry and exit from the loading area 5. When the semi-trailer moves to the loading area 5, the main dust hood 8 descends, as close as possible to the cargo bed and the dust-generating area, to suck up dust earlier and faster, thus improving the dust removal effect.
[0021] The main dust hood 8 has a longitudinal section shaped like a "7". The main dust hood 8 faces the bottom of the truck bed and can be well matched to the top side edge of the truck bed. The other side of the truck bed is convenient for loading. Side dust hoods 9 are rotatably installed on both sides of the main dust hood 8. An angle hydraulic cylinder 10 is installed between the side dust hood 9 and the main dust hood 8. The cylinder body of the angle hydraulic cylinder 10 is hinged to the main dust hood 8, and the telescopic end of the angle hydraulic cylinder 10 is hinged to the side dust hood 9. The angle hydraulic cylinder 10 can drive the side dust hood 9 to rotate horizontally and adjust the angle between it and the main dust hood 8, so that it gets closer to the main dust hood 8. When the side dust hood 9 rotates towards the truck bed, it surrounds the side dead corner, so that the main dust hood 8 and the side dust hood 9 create a local space at the top of the truck bed where the material is fed, which can block and remove the dust in the local space.
[0022] It also includes a dust collector 11. The air inlet of the dust collector 11 is connected to the main dust collector 8 through a flexible hose. The main dust collector 8 is connected to the side dust collector 9 through a corrugated pipe 12. The dust collector 11 provides negative pressure suction to the main dust collector 8 and the side dust collector 9 for dust removal.
[0023] It also includes a controller 13, preferably a PLC controller 13 in this embodiment. Two position sensors 14 for positioning the semi-trailer are respectively provided in the lower half of the bracket 6. When the semi-trailer is parked on one side of the bracket 6, the wheels of the semi-trailer should be sensed by the two position sensors 14 in the lower half of the bracket 6 at the same time.
[0024] A position sensor 14 for positioning the height of the truck bed is provided at the bottom of the main dust hood 8. The signal output terminal of the position sensor 14 is connected to the signal input terminal of the controller 13. The controller 13 is electrically connected to the dust collector 11 and the lifting device 7 respectively. When the main dust hood 8 descends, the bottom of the main dust hood 8 approaches the truck bed. The position sensor 14 at the bottom of the main dust hood 8 senses this and sends a signal to the controller 13, causing the lifting device 8 to stop.
[0025] When the two position sensors 14 simultaneously detect that the semi-trailer's wheels are in position, a signal is sent to the controller 13, which then activates the dust collector 11 to remove dust, achieving automatic, precise, and rapid dust removal.
[0026] The bracket 6 includes an n-shaped gantry 6.1, with a frame 6.2 horizontally fixed to the top of the n-shaped gantry 6.1, and a crossbar 6.3 fixed to the lower half of the n-shaped gantry 6.1. Two position sensors 14 of the lower half of the bracket 6 are fixed to the crossbar 6.3.
[0027] Working principle: When this utility model is in use, the vehicle inlet 3 and vehicle outlet 4 do not interfere with each other when entering and exiting the vehicle. There is a barrier 1. When unloading and loading in the transfer area 2, part of the dust raised is blocked by the barrier 1 and falls back into the transfer area 2, effectively preventing some dust from overflowing.
[0028] When the semi-trailer is parked in loading area 5, on one side of support 6, the wheels of the semi-trailer should be simultaneously sensed by the two position sensors 14 on the lower half of support 6. The signal is sent to controller 13, which causes dust collector 11 to start dust removal, so as to achieve automatic, accurate and fast positioning.
[0029] The lifting device 7 drives the main dust cover 8 to descend to one side above the semi-trailer's cargo bed. The position sensor 14 at the bottom of the main dust cover 8 senses the cargo bed and sends a signal to the controller 13, causing the lifting device 8 to stop. The dust collector 11 provides negative pressure suction to the main dust cover 8 and the side dust cover 9.
[0030] The main dust cover 8 faces the bottom of the truck bed and fits well with the top side edge of the truck bed, while the other side of the truck bed facilitates loading. Figure 1 (As indicated by the arrow) The angled hydraulic cylinder 10 drives the two side auxiliary dust collectors 9 to rotate horizontally, approaching the main dust collector 8, and surrounding the side dead corners, so that the main dust collector 8 and the side auxiliary dust collectors 9 can create a local space at the top of the truck bed feed area, which can block and eliminate the dust in the local space.
[0031] Advantages: This new type of vehicle not only uses the enclosure 1 to reduce dust spillage during unloading and loading, but also uses the main dust hood 8 and the side auxiliary dust hood 9 to get close to the most serious dust in the truck bed, quickly and effectively removing the dust, meeting the needs of environmentally friendly production, improving the hygiene of the working environment for employees, and reducing the possibility of employees developing pneumoconiosis due to dust.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
