[0002] Air conveying system, also known as pneumatic conveying system or air flow conveying system, refers to a method of conveying powder and granular materials in a pipeline by using air flow as a driving force. Air conveying system can realize the integration of multiple production links, so it has been widely used in many industries.

[0003] The centralized collection system for tobacco stems is the most important part of the dust removal system in the tobacco industry. It uses high negative pressure to collect the tobacco stems removed by the rolling and connecting unit in the rolling and packaging workshop to avoid secondary dust in the production area. It is mainly composed of a pipe network system, a stem collecting bucket, a manually adjustable butterfly valve, a cyclone dust collector, a bag dust collector, a high-pressure centrifugal fan, etc. At the same time, it is linked with other dust removal systems through an electronic control system. The materials collected in the centralized collection system for tobacco stems contain some high-quality tobacco shreds and tobacco stems. After being separated and discharged by a cyclone dust collector, they are generally recycled manually.

[0004] In the process of manual recycling, there are some situations where materials are not received in time, which may cause material overflow, environmental pollution, secondary recycling and other problems in a short time. In a long time, it may cause blockage, screw conveyor, ash discharge valve shutdown and other problems. Severe cases may even cause system shutdown and affect production, resulting in great economic losses. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides an intelligent material receiving system that can automatically switch. When the staff fails to receive the materials in time, when one receiving trolley is full, the system will automatically switch to another receiving trolley and issue an alarm at the same time. When both receiving trolleys are full, the system will automatically open the pneumatic emergency unloading device and prompt the alarm upgrade to ensure the stable operation of the production system.

[0006] The utility model is realized by the following technical scheme: an intelligent material receiving system capable of automatic switching, comprising a cyclone dust collector, a screw conveyor, a pneumatic three-way material dividing device, a material receiving protective cover, a material level detection device, a material receiving trolley A and a material receiving trolley B;

[0007] The materials collected by the cyclone dust collector are discharged to the screw conveyor through the bottom ash discharge valve after sedimentation. The outlet of the cyclone dust collector is connected to the inlet of the screw conveyor; the outlet of the screw conveyor is connected to the pneumatic three-way material distributor through a flange, and there is a material receiving protection cover under the pneumatic three-way material distributor. A material receiving trolley A and a material receiving trolley B are arranged inside the material receiving protection cover, and material level detection devices are provided on both sides of the material receiving protection cover for detecting the material level conditions of the material receiving trolley A and the material receiving trolley B.

[0008] The outlet of the cyclone dust collector is connected to the inlet of the screw conveyor by a soft seal.

[0009] A pneumatic emergency unloading device is arranged below the screw conveyor.

[0010] The pneumatic three-way material distributing device is provided with a pneumatic component, a connecting rod and a valve plate. The pneumatic component controls the valve plate to automatically switch the material outlet through the connecting rod.

[0011] The beneficial effect of the utility model is that when the utility model is used in the material air conveying system, when the staff fails to receive the material in time, when one receiving trolley is full, the system will automatically switch to another receiving trolley and issue an alarm prompt at the same time. When both receiving trolleys are full, the system will automatically open the pneumatic emergency unloading device and prompt the alarm upgrade to ensure the stable operation of the production system.
