Abstract
Description
Technical Field
[0001] This utility model relates to an automatic ash discharge valve for a dust removal bin, belonging to the technical field of environmental protection equipment in the metallurgical industry. Background Technology
[0002] In modern steel production, various dust collection points require pipeline connections to deliver gas containing dust particles from different locations into the dust collection system. The dust collection system uses bag filters to separate the gas containing dust particles into two parts: dust and air. The filtered air is discharged into the atmosphere, while the dust is first drawn into a dust collection bin and then transported away using dust removal vehicles.
[0003] Each time the ash transport vehicles are loaded with ash, the ash discharge valve of the dust collection bin needs to be manually opened to release the dust from the bin into the transport vehicles, which are then transported to designated locations for processing. This is time-consuming and labor-intensive, increasing the workload of the workers. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic ash discharge valve for a dust collection bin, which is sensitive and reliable in opening and closing, reduces the labor intensity of workers, and solves the problems existing in the background technology.
[0005] The technical solution of this utility model is:
[0006] An automatic ash discharge valve for a dust collection bin includes a pin, a valve baffle, a counterweight, a valve stem, a dust collection bin, and a dust collection bin discharge port. The valve baffle is an arc-shaped plate, the size of which matches the dust collection bin discharge port at the bottom of the dust collection bin. One side of the valve baffle is rotatably connected to the bottom of the dust collection bin via a pin. The upper end of the valve stem is fixed to the middle of the valve baffle, and the lower end of the valve stem engages with a dust transport vehicle. The counterweight is fixed to the middle of the valve stem. When the valve baffle is in the open state, a valve outlet is formed between the valve baffle and the dust collection bin discharge port, and the dust in the dust collection bin flows into the dust transport vehicle through the valve outlet.
[0007] The valve stop is a bent shape consisting of two vertical stops and one horizontal stop connected together. One of the vertical stops is fixed in the middle of the valve baffle, and the other vertical stop is matched with the dust transport vehicle. The counterweight is fixed on the horizontal stop between the two vertical stops.
[0008] The dust removal chamber has a rectangular discharge port.
[0009] The beneficial effects of this utility model are: the automatic ash discharge valve of the dust collection bin is sensitive, accurate and reliable in opening and closing, eliminating the need for operators to frequently close the valve, reducing the labor intensity of workers and ensuring stable production.

[0015] The present invention will be further described below with reference to the accompanying drawings and examples.
[0016] See attached document Figure 1-4 An automatic ash discharge valve for a dust collection bin includes a pin 1, a valve baffle 2, a counterweight 3, a valve rod 4, a dust collection bin 5, and a dust collection bin discharge port 6. The valve baffle 2 is an arc-shaped plate, and its size matches the dust collection bin discharge port 6 at the bottom of the dust collection bin 5. One side of the valve baffle 2 is rotatably connected to the bottom of the dust collection bin 5 via the pin 1. The upper end of the valve rod 4 is fixed in the middle of the valve baffle 2, and the lower end of the valve rod 4 cooperates with a dust transport vehicle 8. The counterweight 3 is fixed in the middle of the valve rod 4. When the valve baffle 2 is in the open state, a valve outlet 7 is formed between the valve baffle 2 and the dust collection bin discharge port 6, and the dust in the dust collection bin 5 flows into the dust transport vehicle 8 through the valve outlet 7.
[0017] In this example, refer to the appendix. Figure 1-4 The automatic ash discharge valve includes a pin 1, a valve baffle 2, a counterweight 3, a valve stop 4, a dust collection bin 5, and a dust collection bin discharge port 6, wherein:
[0018] The dust collection bin discharge port 6 is rectangular. The valve baffle 2 is an arc-shaped plate that matches the size of the dust collection bin discharge port 6. The valve baffle 4 is a bent shape consisting of two vertical baffles and one horizontal baffle connected together. One of the vertical baffles is fixed in the middle of the valve baffle 2, and the other vertical baffle is matched with the dust transport vehicle 8. The counterweight 3 is fixed on the horizontal baffle. The weight of the counterweight 3 can keep the valve closed when no material is being discharged.
[0019] When the dust transport truck arrives, the self-unloading valve is closed, as shown in the attached image. Figure 1 , 3As shown; when the rear hopper of the dust transport vehicle 8 contacts the vertical stop bar at the lower part of the valve stop bar 4, and as the vehicle moves backward, the valve baffle 2 rotates around the pin 1, so that a valve outlet 7 is formed between the valve baffle 2 and the dust collection bin discharge port 6, even if the self-unloading valve is in the open state, as shown in the attached... Figure 2 , 4 As shown, the dust in the dust removal bin 5 flows into the dust transport vehicle 8 through the valve outlet 7 until the dust transport vehicle 8 is full; when the dust transport vehicle 8 moves forward, the valve stop 4 closes the automatic unloading valve under the action of the counterweight 3.
[0020] After on-site testing, the self-unloading valve performed well, opening and closing sensitively, accurately, and reliably. This mechanical self-unloading valve perfectly solves the problem of operators frequently closing valves, reducing the labor intensity of workers.
