[0001] The invention relates to a propeller blade connection structure and a dryer thereof, belonging to the technical field of drying equipment. Background Art

[0002] In the industrial field of material stirring, mixing and processing, traditional equipment often uses fixed-structure blades for operation. The gaps between these blades are fixed and difficult to flexibly adjust according to material characteristics and process requirements. This fixed gap design limits the fluidity and mixing uniformity of the material during the stirring process, resulting in low material processing efficiency and difficulty in meeting diverse process requirements. In this context, the present invention proposes a propeller blade connection structure and a dryer thereof. Summary of the invention

[0003] The object of the present invention is to provide a propeller blade connection structure and a dryer thereof to solve the problems raised in the above background technology.

[0004] In order to achieve the above object, the present invention adopts the following technical solution: a propeller blade connection structure and a dryer thereof, comprising:

[0005] Rotating shaft;

[0006] A plurality of paddles, wherein the plurality of paddles are evenly distributed on the rotating shaft along the axial direction of the rotating shaft, and a gap capable of accommodating materials is provided between two adjacent paddles;

[0007] Wherein, each of the blades comprises:

[0008] A fixed blade, wherein the fixed blade is fixedly connected to the rotating shaft;

[0009] A movable blade, wherein the movable blade is slidably connected to the fixed blade along the axial direction of the rotating shaft;

[0010] When the movable blade slides on the fixed blade and enlarges the second heat chamber, the gap between two adjacent blades decreases;

[0011] When the movable blade slides on the fixed blade and reduces the second heat chamber, the gap between two adjacent blades expands.

[0012] Preferably, support plates for supporting the ends of the rotating shaft are provided at both ends of the rotating shaft, and bolt holes are provided on the support plates.

[0013] Preferably, a sliding groove is provided on the side wall of the rotating shaft along the axial direction of the rotating shaft;

[0014] A sliding rod is fixed on the inner hole wall of the plurality of movable blades, and the sliding rod is slidably connected inside the sliding groove;

[0015] Both ends of the rotating shaft are slidably sleeved with sliding rings, and the two sliding rings are fixedly connected to the ends of the sliding rod;

[0016] An oil cylinder is fixedly mounted on the side wall of any supporting plate, a ring sleeve is fixed on the output shaft of the oil cylinder, and the ring sleeve is rotatably connected to the sliding ring at the same end.

[0017] Preferably, a first heat chamber is provided inside the rotating shaft, and a second heat chamber is provided between the fixed blades and the movable blades;

[0018] A first heat hole for connecting the first heat chamber and the second heat chamber is provided on the side wall of the rotating shaft.

[0019] Preferably, a plurality of heat pipes are arranged inside the second heat chamber, the center lines of the plurality of heat pipes are arranged parallel to the axis of the rotating shaft, one end of the plurality of heat pipes is fixedly connected to the side wall of the movable blade, and one end of the plurality of heat pipes passes through the fixed blade and extends into the gap;

[0020] The heat pipe is hollow in shape, and a second heat hole capable of introducing heat in the second heat cavity into the heat pipe is provided on the side wall of the heat pipe.

[0021] Preferably, stirring blades are evenly distributed on one end surface of the movable blade away from the fixed blade.

[0022] Preferably, the end surface of the blade is inclined.

[0023] The present application also provides a dryer, comprising the propeller blade connection structure described in any of the above technical solutions.

[0024] Beneficial effects of the present invention:

[0025] The present invention evenly arranges a plurality of blades along the axial direction on the rotating shaft, and each blade is composed of a fixed blade and a movable blade. The fixed blade is firmly connected to the rotating shaft and serves as a reference for the sliding of the movable blade; the movable blade can slide freely along the axial direction on the fixed blade, allowing the size of the gap between adjacent blades to be adjusted by sliding the movable blade. When the movable blade slides to expand the second heat chamber inside it, the gap between adjacent blades naturally decreases, and vice versa. This dynamic adjustment mechanism greatly improves the mixing efficiency of the material in the gap, ensuring that the material can be mixed and processed more evenly and fully.

[0026] The present invention constructs a stable sliding mechanism by providing a slide groove on the side wall of the rotating shaft and slidingly connecting the slide rod fixed in the movable blade in the slide groove. At the same time, the sliding rings slidably sleeved at both ends of the rotating shaft are fixedly connected to the ends of the slide rod, ensuring the synchronization of the sliding of the movable blade. In particular, the cylinder installed on the side wall of any support plate has a ring sleeve fixedly connected to its output shaft and is rotatably connected to the sliding ring at the same end. This design enables the cylinder to drive the sliding ring and the slide rod to move along the axis of the rotating shaft when pushing or pulling the ring sleeve, thereby driving the movable blade to slide on the fixed blade to achieve the adjustment of the gap.

[0039] Embodiment 1

[0040] like Figures 1 to 5As shown, in this embodiment, an air intake disk and a filter thereof are provided, comprising a rotating shaft 1, on which a plurality of blades 2 are evenly distributed along the axial direction of the rotating shaft 1, the end faces of the blades 2 are inclined, and a gap capable of accommodating materials is provided between two adjacent blades 2; wherein each blade 2 comprises a fixed blade 201 and a movable blade 202, wherein the fixed blade 201 is fixedly connected to the rotating shaft 1; and the movable blade 202 is slidably connected to the fixed blade 201 along the axial direction of the rotating shaft 1, as shown in FIG. Figure 3 and Figure 4 As shown, in order to further improve the efficiency of stirring the material in the gap, stirring blades 10 are evenly distributed on one end surface of the movable blade 202 away from the fixed blade 201;

[0041] When the movable blade 202 slides on the fixed blade 201 and enlarges the second heat chamber 203, the gap between two adjacent blades 2 decreases;

[0042] When the movable blade 202 slides on the fixed blade 201 and reduces the second heat chamber 203, the gap between two adjacent blades 2 expands.

[0043] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in order to install the rotating shaft 1 in the dryer in a rotatable manner, support plates 6 for supporting the ends of the rotating shaft 1 are provided at both ends of the rotating shaft 1.

Bolt holes are opened on the support plate 6, and the bolt holes are used to cooperate with bolts to fix the support plate 6 to the dryer.

[0044] Embodiment 2

[0045] like Figure 3-Figure 5 As shown, on the basis of the first embodiment, in order to enable multiple movable blades 202 to slide synchronously, a slide groove 3 is opened on the side wall of the rotating shaft 1 along the axial direction of the rotating shaft 1; a slide rod 4 is fixed on the inner hole wall of the multiple movable blades 202, and the slide rod 4 is slidably connected inside the slide groove 3; both ends of the rotating shaft 1 are slidably sleeved with a sliding ring 5, and the two sliding rings 5 ​​are fixedly connected to the end of the sliding rod 4; an oil cylinder 7 is fixedly installed on the side wall of any support plate 6, and a ring sleeve 8 is fixed on the output shaft of the oil cylinder 7, and the ring sleeve 8 is rotatably connected to the sliding ring 5 at the same end, as shown in FIG. Figure 3 and Figure 4 As shown, a ring groove is provided on the sliding ring 5 connected to the ring sleeve 8, and the ring groove is adapted to the ring sleeve 8.

At the same time, the support plate 6 is provided with two oil cylinders 7, which operate synchronously, and the output axes of the two oil cylinders 7 are symmetrically fixed on the ring sleeve 8.

[0046] The operation process is:

[0047] Process 1: During normal drying, the shaft 1 rotates (a motor for driving the shaft 1 to rotate may be installed on the dryer, and the output shaft of the motor may be connected to the shaft 1 through a transmission member such as a gear or a chain), and the shaft 1 rotates with the fixed blades 201 and the movable blades 202, and the material may be stirred at this time. During this process, the sliding ring 5 rotates synchronously with the shaft 1, and the ring sleeve 8 remains stationary relative to the support plate 6.

[0048] Process 2: When adjusting the gap between two adjacent blades 2, start the oil cylinder 7. At this time, the output shaft of the oil cylinder 7 pulls or pushes the ring sleeve 8 to move along the axis of the rotating shaft 1, causing the ring sleeve 8 to drive the sliding ring 5 to slide. In this way, the sliding ring 5 will slide with the sliding rod 4 inside the sliding groove 3, causing the sliding rod 4 to slide with the movable blade 202 on the fixed blade 201, thereby adjusting the gap between the two blades 2.

[0052] The heat pipe 9 is hollow in shape, and a second heat hole 901 is provided on the side wall of the heat pipe 9 , which can introduce the heat in the second heat cavity 203 into the heat pipe 9 .

[0053] The heat pipe 9 not only efficiently transfers the heat in the second heat chamber 203 to the gap, but also stirs the material in the gap.
