technical field

The utility model relates to the technical field of dust removal equipment, in particular to a dust purifier for bulk grain unloading operations.

Background technique

At present, in the bulk grain storage industry, a common way for grain to enter the warehouse is to transport the grain to the warehouse door by a special vehicle, and then unload the grain in the vehicle into the mobile grain conveyor, and then transport it to the grain warehouse through its own conveyor belt. , after a granary is full, it will be necessary to transport the mobile grain conveyor to the next granary. Therefore, in order to facilitate moving and carrying, the mobile receiving grain conveyor cannot be set to be huge and heavy.

When the grain truck dumps the grain on the mobile grain conveyor, a large amount of dust will be generated. If the dust is directly scattered in the air, it will pollute the environment and even threaten the health of the staff. Moreover, the docking position and grain unloading area of the mobile grain conveyor are different and change frequently. The traditional dust removal device that cannot be moved obviously cannot meet the requirements. For this reason, need to design a kind of dust removal device that can move, and open literature has also reported some dust removal devices, for example:

At this time, the vacuum cleaner connected to the dust suction hole will generate negative pressure at the dust suction hole, and the dust will Follow the airflow into the vacuum cleaner.

3. Chinese patent: a dust removal device for a grain unloader, application number: 201821563931.2, application date: 2018.09.26, abstract: a dust removal device for a grain unloader, one side of the frame (2) At least one vertically upward gray baffle (3) is provided, and an inclined air duct installation plate (4) is provided at the end of the ash baffle (3), and the air duct installation plate (4) is provided with At least two dust removal ports (5), the at least two dust removal ports (5) are respectively fixedly installed with air pipe joints (6) communicated with the dust removal port (5), and the at least two dust removal ports (5) are The air outlet of the air pipe connector (6) is communicated with the inlet of the dust removal fan. The utility model has the advantages that: by arranging a gray plate on one side of the grain unloader and a dust removal port on the top, the influence of dust is avoided, and the working environment of the staff is protected.

4. Chinese patent: dust collection equipment for grain unloading machines, application number: 201921649043.7, application date: 2019.09.30, abstract: the utility model discloses a dust collection equipment for grain unloading machines, which is applied in the technical field of grain transportation equipment and solves the problem of During the process of unloading grain from the vehicle and transporting it to the warehouse, there will be a lot of dust, which will cause dust to spread around the job site and cause adverse pollution to the surrounding environment. The trough is located on the upper part of the frame, the discharge chute is provided with a buffer, and the frame is provided with a dust removal component; the dust removal component includes a dust collection box, a filter set on the dust collection box and a purification piece on one side of the dust collection box , There is a dust suction pipe between the dust collection box and the purification part; the technical effect is to absorb the dust into the purification part, so as to avoid the dust from flying and protect the working environment around the grain unloader.

After application, it is found that the dust in the grain is also a part of the weight of the grain. If the collected dust is not sent into the granary together with the grain, it will easily cause the loss of grain storage in the grain storage enterprise, and if the collected dust cannot be dispersed in time and mixed with the grain If it is sent to the granary, it is easy to cause problems such as insect pests and deterioration in the storage process of the grain. And, although the above-mentioned disclosed dust collection device can collect dust, the collected dust cannot be discharged in time and transported to the granary with grain. Therefore, there is a need for a dust removal device that can not only collect dust, but also mix dust and grain into the granary.
