Description

Technical Field

[0001] The utility model belongs to the technical field of dust prevention for receiving materials in a silo, in particular to a dust prevention device for receiving materials in a silo. Background Art

[0002] In the various production processes of the metallurgical industry, many production raw materials need to be transported and loaded by belt conveyors. For example, the raw material loading system for blast furnace charging, the auxiliary raw material loading system for converter charging, and the sintering machine loading system all use belt conveyors for loading. Various raw materials are put into various silos set up in the system through the mobile material distribution cart of the belt conveyor. Since the silos set up in the system are generally large in size, a lot of dust will be generated when the raw materials are unloaded into the silo by the mobile material distribution cart, which will cause very serious environmental pollution and occupational harm to the health of production workers.

[0003] In the prior art, in order to reduce the pollution of dust to the environment and the harm to the workers, the conventional practice is to add sealing strips to seal the feeding port of the material distribution vehicle and the receiving port of the silo to prevent dust from spreading to the outside from the feeding port of the material distribution vehicle and the receiving port of the silo; at the same time, a dust removal system is set on and outside the material distribution vehicle, and the dust is adsorbed into the dust removal system device through the material distribution vehicle and the dust removal pipeline by the dust removal system for dust removal. Due to the long-term continuous movement of the material distribution vehicle, the sealing strips set at the interface are worn or damaged, and the dust prevention effect is poor. At the same time, the dust adsorbed into the dust removal system device pollutes the dust removal device greatly, and the dust removal facilities inside the dust removal device need to be replaced frequently. And when the material distribution vehicle distributes materials from one silo to the next silo, the dust in the silo that has been distributed previously will still spread dust outward through the receiving port because it has not been completely settled, causing secondary pollution to the environment.

[0035] Preferably, in order to facilitate adjustment of the position of the counterweight 5 and balance it with the dustproof plate so that the dustproof plate is closed, a long hole 8 is opened on the lower horizontal extension part 7, and the counterweight 5 can move closer to or away from the rotating shaft 4 along the long hole 8.

[0036] Preferably, in order to facilitate disassembly, the counterweight block 5 is provided with an adjusting bolt 9, and the adjusting bolt 9 is detachably connected to the elongated hole 8. The number of adjusting bolts 9 is not limited. In this embodiment, the counterweight block 5 is specifically made of a thick steel plate, and two adjusting bolts 9 are installed on the steel plate, and the adjusting bolts 9 and the elongated hole 8 are fixed with nuts.

[0039] Specifically, Figure 3 As shown, a mounting groove 11 is provided at the top of the receiving port 1 for placing the two ends of the rotating shaft 4, and the rotating shaft 4 is rotatably connected to the mounting groove 11. In this embodiment, a mounting groove 11 is provided at a relative position on the top of the opposite side wall of the receiving port 1, and a bearing seat 12 is welded on the mounting groove 11, and a bearing 13 is provided on the bearing seat 12 for mounting the two ends of the rotating shaft 4.
