Technical Field
[0001] The utility model relates to the technical field of solid transportation, in particular to an anti-blocking swing valve for replacing a temporary fuel storage bin. Background Art
[0002] In the cement industry, with the increasing energy consumption requirements and the decline in cement prices, many cement production lines have begun to use alternative fuels to reduce coal consumption. Since the cost of directly using finished alternative fuels is too high, cement production lines will use raw materials for processing by themselves. The overall system is mainly composed of a pre-treatment system, a feeding system, and an external furnace. Since the cement burning system cannot avoid positive pressure flames caused by system fluctuations, a temporary storage bin with a wind-locking flap valve is generally set up. The raw materials (such as waste cloth, plastic waste, etc.) are broken into small pieces through the pre-treatment process, and then fed into the temporary storage bin through the feeding belt and fed into the external furnace for combustion through a spiral reamer.
[0003] Due to the low bulk density and easy agglomeration of raw materials, they are prone to arching in the temporary storage bin, causing blockage in the feeding system, and anti-blocking measures are needed. Utility Model Content

The left end of the connecting block 31 is fixedly connected to the right end of the driving cylinder 2, and the left end of the supporting block 33 is transmission-connected to the right end of the connecting block 31. The crank 3 is transmission-connected to one end of the supporting block 33 that is close to each other through the rotating block 32.
[0032] The seat bearing 4 includes a connecting plate 41, a bolt 42 and a screw 43. There are two seat bearings 4, and two connecting plates 41 are provided. The front ends of the two connecting plates 41 are transmission-connected to the rear end of the crank 3. There are a plurality of bolts 42. The connecting plate 41 is threadedly connected to one end of the two seat bearings 4 that are away from each other through a plurality of bolts 42. A plurality of screws 43 are threadedly connected to the front ends of the two connecting plates 41 through the top end of the crank 3.
[0033] The valve plate 5 is arranged inside the temporary storage bin 1 , and one end of the valve plate 5 that is away from each other is drivingly connected to one end of the two seat bearings 4 that are close to each other.
[0034] The proximity switch 6 includes a fixed block 61, two of which are provided, and the rear ends of the two fixed blocks 61 are fixedly connected to the front end of the temporary storage bin 1. The proximity switch 6 is provided with two, and the surfaces of the two proximity switches 6 are fixedly connected to the front ends of the two fixed blocks 61.
[0035] The implementation principle of an anti-blocking swing valve for replacing a fuel temporary storage bin in the embodiment of the present application is as follows: the swing valve installed on the RDF temporary storage bin 1 is composed of a driving cylinder 2, a crank 3, a seat bearing 4, a proximity switch 6, and a valve plate 5. The valve plate 5 is fixed in the silo by the seat bearings 4 on both sides, and the valve plate 5 is driven by the cylinder and the crank 3, with a motion range of ±60°. The position of the valve plate 5 is detected by the proximity switch 6. The dynamic distribution of the material can be achieved through the linkage control of the swing valve cylinder and the cylinder of the pneumatic flap valve, so that the distribution of the material in the external furnace is more reasonable and uniform. In the case of mixed material feeding, the material with poor flammability can be placed close to the tertiary air side to make the material burn more fully. In the case of a single material, the material can be distributed more evenly in the external furnace, so that the material burns more fully. The valve plate 5 is driven by the cylinder to swing left and right in the silo, so that most of the material can fall directly into the feeding reamer on one side and the lower part thereof along the valve plate 5. A small amount of strip material will also hang on the upper part of the valve plate 5, but will also fall into the other side of the trousers as the valve plate 5 moves, effectively solving the problem of reamer blockage caused by material agglomeration. At the same time, due to the controllability of the material flow direction brought by the swing valve, in the case of one material, the amount of material on the left and right sides can be made consistent, so that the material is more evenly distributed in the external furnace. In the case of mixed feeding of two materials (such as feeding waste tires and waste cloth at the same time), with the air-locking flap valve, the same material can be fed to the same side of the pant, so that the material with poor flammability can be fed close to the tertiary air side for full combustion.
[0036] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
