[0030] An existing stirring dryer includes a drying barrel 100, a cover 200, a stirring frame 400 and a support frame 300. The cover 200 can detachably cover the opening of the drying barrel 100, the upper part of the stirring frame 400 is rotatably connected to the cover 200, the stirring frame 400 extends into the drying barrel 100, and the lower end of the stirring frame 400 is a free end 410, and the support frame 300 is installed in the drying barrel 100 and is used to support and stabilize the lower part of the stirring frame 400, so that the stirring frame 400 with a longer length is not easy to shake when rotating. After a long period of operation or before changing the type of material to be dried, it is necessary to disassemble and remove the cover 200 and the stirring frame 400 to clean the stirring frame 400 and the stirring chamber 110. However, in the above-mentioned stirring dryer, when cleaning the stirring chamber 110 of the drying barrel 100, the support frame 300 often blocks the movement of the cleaning tool, so that the production personnel need to operate the cleaning tool to frequently avoid the support frame 300, which is not convenient for cleaning the stirring chamber 110 of the drying barrel 100.

[0031] Reference Figures 1 to 3 , is a stirring dryer of an embodiment of the utility model, comprising a drying barrel 100, a cover body 200, a support frame 300 and a stirring frame 400. The drying barrel 100 is provided with a stirring chamber 110, and a clearance port communicating with the stirring chamber 110 is provided at the upper end of the drying barrel 100; the cover body 200 is detachably provided at the upper end of the drying barrel 100 and can cover or open the clearance port; the support frame 300 is detachably provided at the drying barrel 100 and is located in the stirring chamber 110, and the support frame 300 can enter or leave the stirring chamber 110 from the clearance port after being disassembled; the upper part of the stirring frame 400 is rotatably provided on the cover body 200, the stirring frame 400 is located in the stirring chamber 110, and the lower end of the stirring frame 400 is a free end 410; the lower part of the stirring frame 400 is rotatably provided on the support frame 300.

[0032] When the drying barrel 100 needs to be cleaned, the cover 200, the stirring frame 400 and the support frame 300 can be disassembled and removed. At this time, when cleaning the inside of the drying barrel 100, the support frame 300 no longer blocks the movement of the cleaning tool, making the cleaning process of the stirring chamber 110 in the drying barrel 100 smoother, thereby making the cleaning of the stirring chamber 110 of the drying barrel 100 relatively convenient.

[0033] Furthermore, a rotary driver is also provided on the cover 200, and the rotary driver is used to drive the stirring frame 400 to rotate. Specifically, the rotary driver can be a device that outputs rotational power, such as a motor or an internal combustion engine, and its output shaft can be directly connected to the upper end of the stirring frame 400, or can drive the stirring frame 400 to rotate by a pulley transmission, or drive the stirring frame 400 to rotate by a gear transmission.

[0034] Specifically, the size of the clearance opening is larger than the support frame 300 , so that the support frame 300 can enter or leave the stirring chamber 110 through the clearance opening.

[0035] Specifically, a feed port is provided on the side wall of the drying barrel 100, and a feed cover plate 500 is pivotally connected to the side wall of the drying barrel 100. The feed cover plate 500 can be rotated to open or close the feed port to facilitate feeding and prevent the material from flowing out through the feed port.

[0036] In the embodiment, the support frame 300 includes a shaft sleeve 310 and three support rods 320. The lower part of the stirring frame 400 is inserted into the shaft sleeve 310. The support rods 320 are evenly distributed around the rotation axis of the stirring frame 400. One end of the support rod 320 is connected to the outer periphery of the shaft sleeve 310, and the other end of the support rod 320 is detachably connected to the wall of the stirring chamber 110. The above-mentioned support frame 300 has a relatively firm support for the stirring frame 400, a relatively simple structure, and saves materials.

[0037] Specifically, a limiting step is provided at the lower portion of the stirring frame 400 , and the limiting step abuts against the upper side of the shaft sleeve 310 . The support frame 300 limits the vertical position of the stirring frame 400 through the limiting step.

[0038] Specifically, the cover 200, the stirring frame 400 and the support frame 300 are moved as a whole when disassembled, and the stirring frame 400 and the support frame 300 are not separated, so that the support frame 300 can be directly taken out during the process of taking out the stirring frame 400. It is understandable that the stirring frame 400 and the support frame 300 can also be separated from each other.

[0039] In the embodiment, the support rod 320 is provided with a plug-in slot 321, the cavity wall of the stirring cavity 110 is provided with a plug-in block 120, and the plug-in slot 321 is plugged into the plug-in block 120. By plugging the plug-in block 120 into the plug-in slot 321, the support frame 300 is detachably connected to the cavity wall of the stirring cavity 110 of the drying barrel 100, which has a simple structure and is easy to implement.

[0040] It is conceivable that a plug-in block 120 may be provided on the support rod 320, and a plug-in groove 321 may be provided on the cavity wall of the stirring chamber 110, and the plug-in block 120 may be inserted into the plug-in groove 321, so that the support frame 300 may be detachably connected to the cavity wall of the stirring chamber 110; or a hook may be provided on the support rod 320, and a groove may be provided on the cavity wall of the stirring chamber 110, and the hook may be detachably connected to the groove, so that the support frame 300 may be detachably connected to the cavity wall of the stirring chamber 110; or a groove may be provided on the support rod 320, and a hook may be provided on the cavity wall of the stirring chamber 110, and the hook may be detachably connected to the groove, so that the support frame 300 may be detachably connected to the cavity wall of the stirring chamber 110.

[0041] In the embodiment, the notch of the plug-in slot 321 is set downward, and the upper part of the plug-in block 120 is tapered with a small top and a large bottom. When the support frame 300 is loaded into the drying barrel 100, the support frame 300 is lowered, and then the tapered upper part of the plug-in block 120 guides the position of the plug-in slot 321, so that the plug-in block 120 is relatively accurately inserted into the plug-in slot 321, which facilitates the accurate insertion of the plug-in block 120 into the plug-in slot 321 without the need for particularly precise alignment and insertion; and the notch of the plug-in slot 321 is set downward, so that the material to be dried is not easy to remain in the plug-in slot 321, reducing the loss of the material to be dried.

[0042] In the embodiment, the upper portion of the support rod 320 is in a tapered shape with a small upper portion and a large lower portion, so as to facilitate guiding the material to be dried to fall without staying above the support rod 320 .

[0043] It is conceivable that the plug-in block 120 may also have a rectangular cross section; the support rod 320 may also have a rectangular cross section.

[0044] Specifically, the support rod 320 is a bent plate body, and the bent plate body forms a plug slot 321 with a notch facing downward, so that the support rod 320 is relatively easy to process and the overall weight of the support frame 300 is relatively light. It is conceivable that the support rod 320 can also be a solid rod body.

[0045] In the embodiment, the support rod 320 is arranged to extend radially along the rotation axis of the stirring frame 400, so that the length of the support rod 320 is as short as possible, the weight of the support frame 300 is reduced, and the structure of the support frame 300 is simplified. It is conceivable that the support rod 320 can also be arranged in a direction tangential to the rotation axis of the stirring frame 400.

[0046] Specifically, one end of the support rod 320 is welded and fixed to the shaft sleeve 310. It is conceivable that one end of the support rod 320 can also be connected to the shaft sleeve 310 by screw locking.

[0047] It is conceivable that the support frame 300 can also be other structures, for example, the support frame 300 includes a shaft sleeve 310 and two support rods 320, and the two support rods 320 are placed on opposite sides of the shaft sleeve 310; or the support frame 300 includes a shaft sleeve 310 and four or more support rods 320; or the support frame 300 includes a shaft sleeve 310 and four criss-crossed support rods 320, and the four support rods 320 form a "well" distribution, and the shaft sleeve 310 is connected to the middle of the four support rods 320; or the support frame 300 includes a vertical top shaft and two or more support rods 320, a rotating shaft hole is set at the lower end of the stirring frame 400, the top shaft is passed through the rotating shaft hole, the support frame 300 is located below the stirring frame 400, and the top shaft limits the shaking of the lower end of the stirring frame 400 when it rotates.

[0048] In the embodiment, the drying barrel 100 includes a tube body 130, an air hood 140 and a blow hood 150. The central axis of the tube body 130 is arranged vertically. The air hood 140 and the blow hood 150 are both arranged around the central axis of the tube body 130. The upper end of the blow hood 150 is connected to the lower end of the tube body 130, the upper end of the air hood 140 is connected to the upper end of the blow hood 150, the lower end of the air hood 140 is connected to the lower end of the air hood 140, the middle part of the air hood 140 is spaced apart from the middle part of the blow hood 150, the blow hood 150 is located on the outside of the air hood 140, the air hood 140 and the blow hood 150 enclose a blow chamber 160, and the blow hood 150 is provided with an air inlet.

[0049] The hot air enters the blast chamber 160 between the breathable cover 140 and the blast cover 150 from the air inlet. Since the breathable cover 140 and the blast cover 150 are both arranged around the central axis of the tube body 130, the blast chamber 160 is annular. At this time, the hot air can evenly pass through the breathable cover 140 into the stirring chamber 110 to form air intake all around, so that the material is dried more evenly during the drying process, further improving the drying effect of the stirring dryer on the material.

[0050] Specifically, the breathable cover 140 is a conical plate with fine mesh, and the blower cover 150 is a conical plate, which is sleeved outside the breathable cover 140. It is conceivable that the breathable cover 140 can also be a hemispherical plate with fine mesh, and the blower cover 150 is a hemispherical plate correspondingly.

[0051] Specifically, the blast hood 150 is connected to an air inlet pipe 170 , and the air inlet pipe 170 delivers hot air into the blast chamber 160 through an air inlet.

[0052] In the embodiment, the distance between the air hood 140 and the blast hood 150 has a tendency to increase first and then decrease in the direction from top to bottom. The blast chamber 160 formed by the air hood 140 and the blast hood 150 has a relatively good drying effect on the material in the drying barrel 100, has a simple structure, and is easy to implement. It is conceivable that the distance between the air hood 140 and the blast hood 150 can also be constant in the direction from top to bottom.

[0053] In the embodiment, a discharge hole 180 is provided at the lower end of the air permeable cover 140 to facilitate the delivery of the dried material out of the dryer to flow into the next process. The structure is simple and the delivery of the material is relatively convenient.

[0054] Specifically, the discharge hole 180 at the lower end of the air hood 140 can be connected to the feed holes of other equipment through a pipeline, and a baffle plate can be set below the air hood 140, and the baffle plate is movably connected to the blower hood 150. When the baffle plate is moved to completely cover the discharge hole 180, the material cannot leave the drying barrel 100; when the baffle plate is moved to partially or completely open the discharge hole 180, the material can leave the drying barrel 100.

[0055] In the embodiment, the blast hood 150 is detachably connected to the tube body 130, the upper end of the blast hood 150 is enclosed with the lower end of the tube body 130, the mounting groove 190 is annular, and the upper edge of the air hood 140 is provided with a mounting ring 141, and the mounting ring 141 is embedded in the mounting groove 190. When assembling the drying barrel 100, firstly, the upper edge of the air hood 140 is placed on the blast hood 150, and then the blast hood 150 is connected to the lower end of the tube body 130 and encloses to form the mounting groove 190, and the mounting groove 190 limits the position of the mounting ring 141, so as to install and fix the air hood 140, and the air hood 140 is fixed by the connection between the blast hood 150 and the tube body 130. When the air hood 140 needs to be cleaned and maintained, the blast hood 150 is disassembled, and the air hood 140 can be directly taken out. The above-mentioned connection structure has a relatively simple assembly structure and is relatively convenient to assemble and disassemble.

[0056] Specifically, the tube body 130 and the air hood 150 can be connected by screw locking, or by rotating a clamping block at the lower end of the tube body 130, which can be rotated to clamp the upper edge of the air hood 150 to achieve the connection between the two. When the clamping block is rotated to disengage from the upper edge of the air hood 150, the air hood 150 can be disassembled and separated from the tube body 130.

[0057] It is conceivable that the breathable hood 140 can also be connected to the blower hood 150 by other means, for example, the breathable hood 140 is connected to the blower hood 150 by screw connection; or the breathable hood 140 is connected to the blower hood 150 by welding; or the breathable hood 140 is connected to the blower hood 150 by riveting.
