Description

Technical Field

[0001] The utility model relates to the field of large-package bag unpacking and unloading, in particular to a dust-free unloading device for ton-bag unloading. Background Art

[0002] At present, there are roughly two ways of unloading ton bags on the market: one is to first hoist the ton bag into the unloading space, then close the ton bag entry and exit door, travel into a closed space, and then start unloading. The dust collector works synchronously, and the negative pressure is created in the unloading interval to reduce dust overflow from the unloading equipment. This type of unloading equipment has a large external dimension, especially the height dimension is generally more than five meters, which is very unfriendly to small space operations. Another unloading method is a half-type unloading device, which has a height dimension of only half of the previous device. After the ton bag is placed on the unloading equipment, the worker needs to bend over and manually unfasten the discharge port, and then put the discharge port on the outside of the unloading barrel, and finally press the unloading barrel to fix the ton bag and the unloading barrel. During the unloading process, the powder is isolated from the outside to avoid dust. This unloading method is not friendly to workers and requires frequent bending over. It is very time-consuming to unfasten the bag, which is not good for health and also affects the unloading efficiency.

[0003] The utility model disclosed (announcement) number: CN218618216U belongs to the technical field of large-package bag unloading, and specifically relates to a dust-free unloading device for ton bag unloading. The utility model is used for ton bags to be unloaded through the device, and the device is provided with a unloading rack that cooperates with the ton bags to achieve dust-free unloading; a sliding mechanism is fixedly provided on the upper side of the unloading rack, and a clamping plate for clamping the discharge port of the ton bag to be unloaded is provided on the sliding mechanism; a unloading channel is fixedly provided below the discharge port of the ton bag to be unloaded and located in the middle of the unloading rack; the clamping plate can be easily moved in a plane and aligned with the bottom plate of the ton bag, and the clamping cylinder is tightened to seal the discharge port of the ton bag with the unloading device to ensure dust-free unloading. The slapping cylinders arranged obliquely on both sides ensure clean unloading, and the filter screen blocks foreign matter from entering the silo. This dust-free unloading device can not only achieve dust-free unloading, but also reduce the physical labor of workers and improve unloading efficiency.

[0004] The device of the above utility model blocks foreign matter from entering the silo by setting a filter screen in the silo. Foreign matter in the material is easily accumulated on one side of the screen, which may cause the screen to be blocked over time, thereby affecting the filtering effect of the screen. The above device must be in the shutdown state to disassemble and clean the filter, which undoubtedly reduces the processing efficiency. Utility Model Content
