Technical Field
[0001] This utility model belongs to the technical field of dust suppression at the bottom of cement clinker silos, and specifically relates to a dust suppression device for the bottom of cement clinker silos. Background Technology
[0002] Cement clinker is an intermediate product in cement production, a lumpy material formed by the high-temperature calcination of raw materials such as limestone and clay. It needs to be stored in large silos. During the discharge and transportation of cement clinker from the bottom of the silos, dust is generated due to the high fluidity and fine particles of the material. This dust not only pollutes the environment and harms workers' health but also may cause raw material waste and safety hazards. Therefore, appropriate dust suppression measures are necessary in related production processes. Most common dust suppression devices consist of only a single dust collection hood and related structures. However, after prolonged use, dust accumulates on the inner surface of the dust collection hood, gradually reducing its dust collection efficiency. Therefore, periodic cleaning of the dust collection hood and related components is required. A single dust collection hood and related structures may prevent continued dust collection from the bottom of the cement silo during cleaning operations, leading to production interruptions. Furthermore, the interruption of dust collection may cause dust to escape, thus affecting the actual dust suppression effect.
[0003] In summary, the dust suppression device for the bottom of cement clinker silos with a single dust hood and related structures has some problems in use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content

[0009] In a preferred embodiment, a set of limiting tooth gaps is formed between two adjacent sets of limiting teeth and engages with the engaging teeth, and an engaging block is connected to the rear side of the push plate via a rotating shaft.
[0010] The rear side of the limiting seat is provided with a locking groove. The locking block drives the push plate to move to the right and rotates it to engage with the locking groove. The locking teeth are embedded in the limiting tooth gap formed by the two sets of limiting teeth, which can complete the limiting fixation after the rotation of the rotating shaft is adjusted.
[0011] In a preferred embodiment, a telescopic hose is fixedly connected to the rear side of the vacuum pipe, and the sewage conduit is a flexible telescopic pipe structure.

The outside of the vacuum tubes is fixed by locking rings, and the two sets of locking rings are connected by a central shaft, which can realize the linkage control of the two sets of vacuum tubes and facilitate the independent assembly and disassembly of the vacuum tubes.
[0014] After adopting the above technical solution, the beneficial effects of this utility model are:
[0015] By adding a dust collection component and a fixing component, the throttle rotation drives the rotating shaft to rotate, allowing the two sets of dust collection hoods to be switched. After the switching is completed, the restriction on the locking block is removed, allowing the limit spring to drive the locking teeth to be placed in the limit tooth gap between the two sets of limit teeth, completing the fixing after the switching. The valve of the dust collection hood that needs to be cleaned is closed to allow the cleaning wastewater to be discharged through the wastewater pipe, thereby enabling continuous dust adsorption operation.
[0016] By adding a vacuuming assembly, the outer side of the vacuum hose is secured with locking rings, and the two sets of locking rings are connected by a central shaft, enabling the linkage control of the two sets of vacuum hoses and facilitating the independent assembly and disassembly of the vacuum hoses.
