[0036] Example 2

[0037] On the basis of Example 1, the preferred embodiment of the drying device for producing mancozeb provided by the utility model is as follows Figures 1 to 6 As shown: the anti-blocking component 8 includes a slide bar 801, which is fixedly connected to the bottom end of the heating sleeve 6 on one side of the discharge pipe 5, a return spring 803 is wound on one side of the surface of the slide bar 801, and a slider 802 is movably connected to the surface of the slide bar 801 at one end of the return spring 803, and a slide plate 805 is fixedly connected to the bottom end of the slider 802, and a rubber block 804 is fixedly connected to the upper and lower ends of one side of the slide plate 805, and a driving block 806 is fixedly connected to the middle position of the other side of the slide plate 805, and a driving motor 808 is fixedly connected to the bottom end of the heating sleeve 6 on one side of the slide bar 801, and a cam 807 is fixedly connected to the output end of the driving motor 808 through a coupling. When the driving motor 808 is started, the cam 807 is driven to rotate and periodically contact the driving block 806, and the elastic force of the return spring 803 is used to make the sliding plate 805 slide back and forth to drive the rubber block 804 to slide and collide with the surface of the discharge pipe 5, thereby facilitating the vibration-proof discharge of the discharge pipe 5.

[0038] In this embodiment, a sliding structure is formed between the slider 802 and the surface of the slide bar 801, and the bottom end of the slider 802 and the top end of the slide plate 805 are welded into an integrated structure. The sliding of the slider 802 and the surface of the slide bar 801 makes the sliding of the slide plate 805 more stable and smooth.

[0039] In this embodiment, one side of the rubber block 804 is arc-shaped, and the other side of the rubber block 804 is fixedly connected to one side of the sliding plate 805 by bolts. The arc-shaped rubber block 804 is used to facilitate contact and collision with the surface of the discharge pipe 5.

[0040] In this embodiment, the driving block 806 is arc-shaped in top view, and the driving block 806 and the cam 807 are in the same horizontal plane. The driving block 806 and the cam 807 are in the same horizontal plane so that they are in closer rotational contact to drive the sliding plate 805 to slide.

[0041] In addition, the cross-section of the turning rod 12 is T-shaped, and the turning rods 12 are evenly spaced and cross-distributed on the upper and lower ends of the surface of the stirring rod 11. The T-shaped turning rod 12 can be used to stir and dry the mancozeb along the surface of the stirring rod 11, and the tip of the turning rod 12 can also break up the blocky mancozeb, which is convenient for subsequent drying treatment.

[0042] The working principle and use process of the utility model are as follows: firstly, mancozeb is added into the drying cylinder 7 through the feed hopper 2, and at this time, steam is transported into the heating jacket 6 through the air inlet pipe 9, so as to heat and dry the mancozeb in the drying cylinder 7, and at the same time, the servo motor 10 is started to drive the stirring rod 11 to rotate, so that the turning rod 12 rotates to stir and dry the mancozeb, and the tip of the turning rod 12 can also break the blocky mancozeb, so as to facilitate the subsequent drying process;

[0043] At the same time, during the drying process, the circulating fan 103 is started to suck the hot air containing moisture in the drying cylinder 7 into the dehumidification box 102, and the silica gel drying plate 104 is used to adsorb and remove the moisture, and then the dried hot air is transported to the inside of the drying cylinder 7 again to achieve a circulating drying process, thereby avoiding the heat loss caused by the direct discharge of this part of the heat, and improving the environmental protection of the device and the efficiency of drying mancozeb;

[0044] When the drying of mancozeb is completed and the material is discharged through the discharge pipe 5, the driving motor 808 can be started to drive the cam 807 to rotate, and periodically contact the driving block 806, so that the sliding plate 805 slides to drive the slider 802 to slide on the surface of the slide rod 801 to compress the return spring 803, until the rubber block 804 is driven to collide with the surface of the discharge pipe 5. After the cam 807 rotates away, the elastic force of the return spring 803 is used to make the slider 802 slide and drive the sliding plate 805 to return to its original position, and then the back and forth sliding of the rubber block 804 and the collision and collision with the surface of the discharge pipe 5 are used to facilitate the vibration-proof discharge of the discharge pipe 5, so as to avoid the blockage of the powdered mancozeb inside the discharge pipe 5 and the poor discharge.

[0045] And after the drying operation is completed, the positioning frame 108 is toggled to drive the sliding block 109 to slide and compress the fixing spring 111 until it completely disengages from the inside of the positioning hole 107. Then, the silica gel drying plate 104 is taken out of the dehumidification box 102 through the sealing plate 101, which is convenient for replacing the silica gel drying plate 104 with saturated adsorption. During installation, the sealing plate 101 is snapped into the installation groove 105, and the sealing ring 106 is used to improve the sealing performance between the lower end of the sealing plate 101 and the inside of the installation groove 105. At the same time, by using the elastic force of the fixing spring 111, the sliding block 109 slides to drive the positioning frame 108 to slide and snap into the inside of the positioning hole 107, realizing the firm and stable limit of the snap-fit installation of the sealing plate 101.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
