[0034] An existing drying device includes a drying barrel 100, a ventilation cover 200 and an air inlet cover 400. The ventilation cover 200 is in an inverted cone shape. The ventilation cover 200 is located at the lower end of the drying barrel 100 and encloses the drying barrel 100 to form a drying chamber 300. The lower end of the ventilation cover 200 has a discharge port 210. The upper end of the drying barrel 100 has a feed port 110. The air inlet cover 400 is sleeved on the outer periphery of the ventilation cover 200. The air inlet cover 400 and the ventilation cover 200 enclose a blast chamber 500. The lower end of the air inlet cover 400 is provided with an air inlet 410. When the device is used, the material is put into the drying chamber 300 from the feed port 110, and the hot air is blown into the blast chamber 500 from the air inlet 410 from bottom to top, and is dispersed and blown into the drying chamber 300 through the inverted cone-shaped ventilation cover 200, so that the material can be air-dried. In the above equipment, the effect of the air permeable cover 200 in dispersing the hot air is not uniform enough, so that the drying effect of the material in the drying chamber 300 is not uniform enough, which affects the drying quality.

[0035] Reference Figures 1 to 3, is a uniform drying device of an embodiment of the utility model, comprising a drying barrel 100, a ventilation cover 200, an air inlet cover 400 and a throttle ring 600. The drying barrel 100 is provided with a feed port 110 at the upper end and an opening at the lower end; the ventilation cover 200 is provided on the drying barrel 100 and covers the lower end opening of the drying barrel 100, and the ventilation cover 200 and the drying barrel 100 are enclosed to form a drying chamber 300, the ventilation cover 200 is in an inverted cone shape, and a discharge port 210 is provided at the lower end of the ventilation cover 200; the air inlet cover 400 is provided on the outer periphery of the ventilation cover 200 and is enclosed with the ventilation cover 200 to form a blast chamber 500. 00, the air inlet hood 400 is in an inverted cone shape, and a downward-facing air inlet 410 is provided at the lower end of the air inlet hood 400; a plurality of throttle rings 600 are provided and are arranged in the area outside the upper and lower ends of the air hood 200, and the throttle rings 600 are arranged axially at intervals along the vertical center axis of the air hood 200, the throttle rings 600 are located in the blowing chamber 500 and are spaced apart from the air inlet hood 400, and the throttle rings 600 are arranged around the center axis of the air inlet 410.

[0036] The hot air enters the lower end of the blast chamber 500 from the air inlet 410 and flows upward. During the upward flow, the hot air gradually passes through the air cover 200 and is dispersed and blown into the drying chamber 300. In addition, since the horizontal cross-sectional area of ​​the blast chamber 500 increases from bottom to top, the pressure and flow rate of the hot air in the blast chamber 500 gradually decrease from bottom to top. The flow rate of the hot air passing through the air cover 200 and blowing into the drying chamber 300 gradually decreases from bottom to top. A throttling ring 600 is provided in the domain, so that when the hot air flows from bottom to top along the blast chamber 500, the local air flow pressure at the throttling ring 600 increases, so that the flow rate of the hot air in the vicinity of the air hood 200 corresponding to the throttling ring 600 blowing into the drying chamber 300 increases, and the difference in the flow rate of the hot air blowing into the drying chamber 300 from various parts of the air hood 200 is reduced. The air hood 200 disperses the hot air more evenly, thereby making the drying effect of the material in the drying chamber 300 more uniform, thereby improving the drying quality.

[0037] Specifically, the air cover 200 is a mesh structure, so that hot air can enter the drying chamber 300 from the blast chamber 500 through the air cover 200. It is understandable that the air cover 200 can also be an inverted cone-shaped plate with a plurality of air holes formed thereon.

[0038] In the embodiment, seven throttling rings 600 are provided. By providing multiple throttling rings 600, the local air flow pressure at multiple locations other than the upper and lower ends of the air hood 200 is increased, and the flow rate of hot air from multiple locations of the air hood 200 blowing into the drying chamber 300 is accelerated, thereby further equalizing the flow rate of hot air from various locations of the air hood 200 blowing into the drying chamber 300, and achieving a better and more uniform drying effect on the material in the drying chamber 300.

[0039] It is conceivable that the throttling ring 600 may be provided in other numbers, such as one, two, three or more than three, and those skilled in the art may configure the throttling ring 600 according to actual needs.

[0040] In the embodiment, the throttle ring 600 extends vertically, and the height of the throttle ring 600 tends to increase from bottom to top. The airflow pressure of the blast chamber 500 decreases slowly from bottom to top. By increasing the vertical length of the throttle ring 600, the airflow pressure at each throttle ring 600 arranged axially along the vertical center axis of the air hood 200 can be more balanced, so that the airflow pressure at multiple locations other than the upper and lower ends of the air hood 200 is relatively balanced, that is, the flow rate of hot air blowing into the drying chamber 300 through various locations of the air hood 200 is relatively uniform. It is conceivable that the vertical lengths of each throttle ring 600 can also be balanced.

[0041] In the embodiment, the distances between the connection ends of any two adjacent throttling rings 600 and the air permeable cover 200 are equal, so as to further even out the flow rate of hot air from all parts of the air permeable cover 200 blowing into the drying chamber 300 .

[0042] In the embodiment, the air inlet 410 is arranged around the discharge port 210 and is located on the outside of the discharge port 210, so that the air flow pressure around the inverted cone-shaped breathable hood 200 is relatively balanced, avoiding the situation where the air flow pressure is higher on one side of the inverted cone-shaped breathable hood 200 and the air flow pressure is lower at other positions, thereby causing a large difference in the flow rate of hot air blown into the drying chamber 300 from the four sides of the breathable hood 200. The structure is simple and easy to implement.

[0043] In the embodiment, the lower end of the breathable cover 200 is provided with a discharge pipe part 220, the discharge pipe part 220 forms the discharge port 210, the lower end of the air inlet cover 400 is provided with an air inlet pipe part 420, the air inlet pipe part 420 forms the air inlet 410, the air inlet pipe part 420 is sleeved on the outer periphery of the discharge pipe part 220, and the air inlet pipe part 420 is coaxially arranged with the discharge pipe part 220. The above structure forms the air inlet 410 arranged around the outer side of the discharge port 210, and because the air inlet pipe part 420 is coaxially arranged with the discharge pipe part 220, the air volume blown into the surrounding of the blast chamber 500 by the air inlet pipe part 420 through the air inlet 410 is relatively balanced, thereby improving the effect of hot air uniformly entering the drying chamber 300 through all parts around the breathable cover 200.

[0044] In the embodiment, the distance between the breathable cover 200 and the air inlet cover 400 tends to decrease from bottom to top, which is convenient for slowing down the flow rate and pressure attenuation rate of the hot air in the blast chamber 500 from bottom to top, and improving the ability of the breathable cover 200 to disperse the hot air.

[0045] In the embodiment, the device further includes a dispersion rack 700 and a rotary driver 800. The dispersion rack 700 is rotatably disposed on the drying barrel 100 and located in the drying chamber 300. The rotary driver 800 is disposed on the drying barrel 100 and is used to drive the dispersion rack 700 to rotate. The rotary driver 800 drives the dispersion rack 700 to rotate. When the material is put into the drying chamber 300, the dispersion rack 700 can continuously stir and disperse the material, so that the surface of the material particles can better contact the hot air blown into the drying chamber 300 from the air permeable cover 200, thereby achieving a better drying effect on the material.

[0046] Specifically, the dispersion rack 700 includes a vertically arranged rotating shaft and a plurality of rod bodies, the rod bodies are arranged along the radial direction of the rotating shaft, one end of the rod body is connected to the rotating shaft, the rotating driver 800 drives the rotating shaft to rotate, and the rotating shaft drives the plurality of rod bodies to rotate together; the rotating driver 800 uses a motor. It is conceivable that the dispersion rack 700 can also be other structures, for example, the dispersion rack 700 includes a connecting shaft and a plurality of inclined rod bodies, the lower end of the connecting shaft is connected to the upper end of the rod body, the rotating driver 800 drives the connecting shaft to rotate, and the connecting shaft drives the plurality of rod bodies to rotate to disperse the materials; the rotating driver 800 can also be a structure that uses an internal combustion engine or the like to output rotational power.

[0047] In the embodiment, the drying barrel 100 includes a barrel 120 and a cover 130, the upper end of the barrel 120 is provided with an opening, the cover 130 is detachably provided at the upper end of the barrel 120 and covers the upper end opening of the barrel 120, the cover 130 is provided with a feed port 110, the dispersion rack 700 is rotatably connected to the cover 130, and the rotary driver 800 is provided at the cover 130 and connected to the dispersion rack 700. When the drying chamber 300 needs to be cleaned when replacing the material, the cover 130 can be removed from the barrel 120, at which time the dispersion rack 700 and the rotary driver 800 are separated from the barrel 120 along with the cover 130, which can facilitate the production personnel to clean the internal space of the barrel 120, and can also clean the dispersion rack 700 to avoid the risk caused by mixing when the materials are dried.

[0048] Specifically, the cover 130 is placed on the upper end of the cylinder 120, so that the cover 130 is detachably arranged on the cylinder 120. It is conceivable that the cover 130 can also be screwed to the cylinder 120, and when the screws are removed, the cover 130 can be separated from the cylinder 120 to clean and maintain the drying chamber 300.

[0049] In the embodiment, a stabilizing frame 900 is further included. The upper portion of the dispersion frame 700 is rotatably connected to the cover body 130.

The stabilizing frame 900 is provided so that when the dispersion frame 700 stirs the dispersed material, the rotation of the dispersion frame 700 can be more stable and not easy to shake, thereby reducing the risk of excessive wear of the dispersion frame 700 and noise generation.
