This utility model provides a dust cleaning device for a masterbatch mixing silo, relating to the field of masterbatch mixing silos. The device includes a mixing silo with a dust collection hood on top. A discharge silo is located on top of the dust collection hood. A through-hole is opened in the top of the discharge silo and a sealed box is fixedly connected thereto. Multiple rotating rods are rotatably connected inside the discharge silo, and baffles are fixedly connected to the outer sides of the rotating rods. A feed pipe is fixedly connected to the through-hole in the top of the mixing silo. This utility model allows for free opening and closing of the mixing silo during use, preventing dust from escaping during mixing and facilitating discharge. Furthermore, the device effectively absorbs and seals the dust during discharge, reducing dust escape and solving the environmental pollution and raw material waste caused by dust overflow from the mixing silo during masterbatch production, particularly addressing the difficulty in effectively controlling dust escape during the feeding process.

This utility model relates to a docking-type loading device. In actual production, when loading a tanker truck is required, the tanker truck can be driven to below the discharge nozzle. Then, the lifting drive assembly is activated, causing the outer telescopic soft sleeve and telescopic sleeve assembly to extend, allowing the discharge nozzle to enter the loading port of the tanker truck. Subsequently, the bulk loader is activated, guiding the material into the feeding pipe. The material then enters the interior of the telescopic sleeve assembly through the feeding pipe and is then guided into the interior of the tanker truck through the discharge nozzle. Simultaneously, the exhaust fan can be activated, drawing the material dust between the telescopic sleeve assembly and the outer telescopic soft sleeve into the dust suction pipe. The dust then reaches the inside of the collection pipe and is discharged into the hopper through the ash discharge pipe. This effectively reduces dust emission, protects the factory environment, avoids material waste, and prevents the health of workers from being affected.

The present application relates to the technical field of construction positioning and line laying, and particularly relates to a positioning and line laying device and system. The present application comprises a lime bin, a wheel and a handle, the lime bin and the wheel are rotationally connected, the handle is rotationally connected with the wheel, further comprises a measuring assembly, the measuring assembly is connected on the wheel, the lime bin comprises a feeding port and a discharging port, a stirring impeller is rotationally arranged at the discharging port. The lime bin and the wheel are controlled and pushed by the handle, the operation is simple, a single person can operate, the flexibility is high, the traditional line laying and lime spreading trolley can be replaced, the line laying work is suitable for various terrains and environments, the measuring assembly is used for recording the actual movement distance and movement track of the line laying device, computer identification and recording are facilitated, subsequent construction reference is facilitated, the stirring impeller is beneficial to lime spreading in the lime bin, reduces problems such as blockage, and makes the lime spreading uniform and clear.

The application relates to an environment-friendly recovery treatment process for spinning waste, and relates to the technical field of waste silk treatment, which comprises the following steps: a covering step of covering a filter screen on an air outlet hole; a cleaning step of cleaning fluff on the surface of the filter screen; a surface changing step of covering the other surface of the filter screen on the air outlet hole; and a collecting step of connecting an opening of a negative pressure device and a waste silk box, and locating the position of the air outlet hole covered by the filter screen in the collecting range of the negative pressure device. The application has the advantage that the probability of fluff being blown out to the environment can be reduced.
