Description

Technical Field

[0001] The utility model relates to the technical field of fumigation, in particular to a circulating fumigation device for uniform fumigation. Background Art

[0002] A circulating fumigation device is a device used to fumigate objects or environments. It generates surrounding hot steam and causes the hot steam to circulate inside the device, thereby effectively distributing the hot steam evenly to the surface and interior of the treated object. Therefore, this device is usually used for grain fumigation, so that the grain can be kept longer after the fumigation operation.

[0003] A multi-bin circulation automatic fumigation device with announcement number CN220571409U is based on the fumigation bin. A lower box is fixed to the bottom side of the fumigation bin, and a fumigation mechanism is provided at the bottom end of the inner side of the lower box. Diverter pipes are fixed at both ends of the inner wall of the fumigation bin, and the diverter pipes are arranged through the two ends of the inner side of the fumigation bin. The two ends of the diverter pipes are fixed to the two ends of the top side of the fumigation mechanism. The fumigation mechanism generates steam by heating the agent, and with the cooperation of the diverter pipe and the fumigation plate, the steam is transported to the inside of the fumigation bin, thereby fumigating the grain. At the same time, the circulation fan is controlled to drive the steam circulation inside the fumigation bin, thereby improving the fumigation efficiency of the grain and ensuring that the grain can be fully fumigated.

[0004] There are still problems in the multi-bin circulating automatic fumigation device described above. During the process of fumigating grain, the grain needs to be stored inside the device in sequence, taken out after the fumigation operation is completed, and replaced with the next batch of grain for fumigation. The cumbersome operation leads to low processing efficiency of the fumigation device, and thus a circulating fumigation device with uniform fumigation is proposed. Utility Model Content

At the same time, the driving mechanism drives the hollow tube 5 to rotate, thereby pushing the grain to move inside the cylinder 1 through the spiral blade 6, and the grain can be fully fumigated inside during the movement. At the same time, the air pump 9 is turned on, and with the cooperation of the output pipe 10 and the input pipe 11, the steam inside the cylinder 1 is driven to circulate, and the fumigated material will be transported to one end inside the cylinder 1 for output, thereby realizing the function of continuous fumigation processing and making the fumigation efficiency of the device higher.

[0026] Working principle: The circulating fumigation device is a device used to fumigate objects or environments. It generates circumferential hot steam and causes the hot steam to circulate inside the device, thereby effectively distributing the hot steam evenly to the surface and interior of the treated object. Therefore, the device is usually used for grain fumigation, so that the grain after fumigation can be kept for a longer time. In the process of fumigating grain, the existing fumigation device needs to store the grain inside the device in turn, take it out after the fumigation operation is completed, and replace it with the next batch of grain for fumigation. The cumbersome operation leads to low processing efficiency of the fumigation device. In order to solve this problem, a fumigation mechanism and a feeding mechanism are set up, and the handle 23 is pulled to open the movable door 22. At this time, material can be added to the inside of the cylinder 1, and the output valve 7 is opened to output the medicinal vapor inside the fumigation box 101. With the cooperation of the conduit 8, it is respectively transported to the inside of the cavity 2 and the hollow tube 5, and then ejected from the air hole 3 and the through hole 51, thereby fumigating the grain inside the cylinder 1, and the air pump 9 is turned on during the fumigation process. Under the cooperation of the output pipe 10 and the input pipe 11, the steam inside the cylinder 1 is driven to circulate, and the servo motor 14 is controlled to drive the small pulley 15 at the output end to rotate, so that the belt 16 and the large pulley 12 cooperate to provide power for the hollow tube 5 to rotate inside the cylinder 1. At this time, the spiral blade 6 will push the grain to move inside the cylinder 1, and the fumigated grain will be transported to the feeding port 17 at one end of the inner side of the cylinder 1. At this time, the grain pushes the slider 19 down along the direction of the limit rod 20 by its automatic weight, prompting the material to be discharged from the feeding port 17, thereby realizing the function of automatic material output. After the material is output, the spring 21 pushes the slider 19 up by its own elastic force, so that it is re-installed at the feeding port 17 to prevent the steam inside the cylinder 1 from leaking. In addition, during the fumigation process, the movable door 22 can be opened at any time to continuously add grain material to the inside of the cylinder 1, so that the fumigation device can continue to perform fumigation processing, thereby improving the fumigation efficiency of the fumigation device and solving the problem of low fumigation processing efficiency of the existing fumigation device.
