Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt processing and application technology, and in particular to an anti-sticking spiral mixing blade and its mixing structure. Background Technology
[0002] In the production process of industries such as asphalt, it is often necessary to use mixing equipment to mix materials. Spiral mixing blades are an important component of mixing equipment, and their performance directly affects the mixing effect and production efficiency.
[0003] However, in the existing spiral mixing blades, materials tend to stick to the blade surface during the mixing process, which not only affects the uniformity of mixing and reduces mixing efficiency, but also requires regular cleaning of the blades, increasing labor costs and downtime. This problem is particularly serious for some highly viscous materials, which greatly restricts the normal operation of the mixing equipment. Therefore, this utility model proposes an anti-sticking spiral mixing blade and its mixing structure. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an anti-sticking spiral stirring blade and its stirring structure, so as to solve the problem that existing spiral stirring blades are prone to sticking to materials.
[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing an anti-sticking spiral stirring blade and its stirring structure, including a spiral blade body, wherein the spiral blade body is made of polytetrafluoroethylene material, and the surface of the spiral blade body is coated with a polytetrafluoroethylene anti-stick coating to fill the surface defects of the spiral blade body after integral manufacturing. The upper surface of the spiral blade body is arc-shaped from the middle to both sides to allow asphalt to slide off.
[0006] A stirring structure for anti-sticking spiral stirring blades includes a drive shaft to drive the rotation of multiple spiral blade bodies. Fixed sleeves are respectively installed at both ends of multiple helical blade bodies, and the opposite faces of multiple sets of fixed sleeves are fixedly connected to the drive shaft; Bolts are installed on the flow guide assembly at the end face of the fixed sleeve to draw asphalt away from the center of the mixing zone toward the center.
[0007] The above technical solution facilitates the rotation of multiple spiral blades via a fixed sleeve, continuously lifting and tumbling the internal asphalt. Then, an external guide component guides the tumbled asphalt to the center, thereby achieving circular tumbling and mixing and improving the overall mixing efficiency.
[0008] The present invention is further configured such that the plurality of helical blade bodies are arranged in three, and are evenly distributed around the drive shaft in the circumferential direction, while the inner wall of the helical blade body is far away from the outer wall of the drive shaft.
[0009] The above technical solution facilitates the rapid lifting and mixing of the asphalt at the center using three spiral blades, preventing the low mixing efficiency of a single spiral blade. At the same time, the inner wall of the spiral blade body does not contact the drive shaft, ensuring that the asphalt on the blade can slide off and prevent it from sticking to the blade.
[0010] The present invention is further configured such that: the flow guiding assembly includes a flow guiding plate, and connecting rods are bolted to both ends of the flow guiding plate, and the two connecting rods are respectively installed inside the fixed sleeve.
[0011] The above technical solution facilitates the rotation of the connecting rod by using the fixed sleeve, thereby causing the set guide plate to rotate. The set tilt angle continuously guides the asphalt from the periphery to the center to participate in the mixing operation, thereby improving the mixing efficiency of the asphalt.
[0012] The present invention is further configured such that: a movable groove is provided inside the fixed sleeve, the connecting rod is inserted into the inside of the fixed sleeve through the movable groove, and a bolt threaded through the outer wall of the fixed sleeve is used to abut against the outer wall of the connecting rod.
[0013] The above technical solution allows the connecting rod to move inside the fixed sleeve when adapting to different mixing chambers, thereby achieving the radius of rotation and improving convenience in the asphalt mixing process.
[0014] The present invention is further configured such that: the guide plate is generally arc-shaped, and both ends of the guide plate are fixedly connected to a rotating shaft, which is rotatably connected to a positioning hole near the end face of two connecting rods through the rotating shaft.
[0015] The above technical solution facilitates the continuous guidance of asphalt from the outer periphery to the inner center during asphalt mixing using an arc-shaped setting. Furthermore, when adjusting the angle, the asphalt can be rotated using a rotating shaft to adjust the guiding angle and achieve stable rotation within the positioning hole.
[0016] The present invention is further configured such that: locking grooves are symmetrically provided at both ends of the guide plate near the side wall, and adjusting grooves are provided at the corresponding positions of the two connecting rods and the locking grooves, and are threadedly connected to the locking grooves by bolts passing through the adjusting grooves.
[0017] The above technical solution facilitates the angle adjustment of the guide plate, which can move inside the adjustment groove and is fixed in position by bolt connection and locking groove, thereby continuously guiding the external asphalt to the center for mixing during use.
[0018] The beneficial effects of this utility model are as follows: 1. The present invention proposes an anti-sticking spiral stirring blade and its stirring structure by coating the surface of the spiral blade made of polytetrafluoroethylene with a polytetrafluoroethylene coating, which can fill the defects on the surface of the blade, making the blade surface smooth and preventing asphalt from sticking to the surface of the blade during the stirring process. 2. The present invention proposes an anti-sticking spiral mixing blade and its mixing structure, which is equipped with a flow guiding component on the outside of the anti-sticking blade, so that it can guide the asphalt far from the center to the center, thereby improving the mixing efficiency of the asphalt.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0022] like Figure 1 and Figure 2As shown, an anti-sticking spiral mixing blade includes a spiral blade body 2, which is made of polytetrafluoroethylene (PTFE) material. The surface of the spiral blade body 2 is coated with a PTFE anti-stick coating to fill the surface defects of the spiral blade body 2 after integral manufacturing. The upper surface of the spiral blade body 2 is arc-shaped from the middle to both sides to allow asphalt to slide off, thereby preventing asphalt from sticking to the outer wall of the spiral blade body 2.
[0023] like Figures 1-4 As shown, a stirring structure for an anti-sticking spiral stirring blade includes a drive shaft 1 to drive the rotation of multiple spiral blade bodies 2. The multiple spiral blade bodies 2 are arranged in three parts and are evenly distributed around the drive shaft 1 in the circumferential direction. At the same time, the inner wall of the spiral blade body 2 is far away from the outer wall of the drive shaft 1, which facilitates the rapid lifting and stirring of the asphalt at the center by the three spiral blade bodies 2, preventing the low stirring efficiency of a single spiral blade. Meanwhile, the inner wall of the spiral blade body 2 does not contact the drive shaft 1, which can ensure that the asphalt on the blade can slide off and prevent it from sticking to the blade. Fixed sleeves 3 are installed at both ends of multiple spiral blade bodies 2, and the opposite faces of multiple sets of fixed sleeves 3 are fixedly connected to the drive shaft 1. The fixed sleeve 3 has a movable groove inside, and the connecting rod 42 is inserted into the inside of the fixed sleeve 3 through the movable groove. The bolts that are threaded through the outer wall of the fixed sleeve 3 are pressed against the outer wall of the connecting rod 42. This allows the connecting rod 42 to move inside the fixed sleeve 3 when adapting to different mixing chambers, thereby realizing the radius of rotation and improving the convenience in the asphalt mixing process.
[0024] like Figure 3 and Figure 4As shown, the guide assembly 4, bolted to the end face of the fixed sleeve 3, directs asphalt away from the center of the mixing zone towards the center. The guide assembly 4 includes a guide plate 41, which is arc-shaped. Both ends of the guide plate 41 are fixedly connected to a rotating shaft 411, which is rotatably connected to two connecting rods 42 near the end face of the positioning holes 422. This allows the asphalt to be continuously guided to the center during mixing by utilizing the arc shape. Furthermore, the angle can be adjusted by rotating the shaft 41 to adjust the guiding angle. The flow can be further adjusted within the positioning holes 422. Stable rotation is achieved by bolting connecting rods 42 to both ends of the guide plate 41, with the two connecting rods 42 respectively installed inside the fixing sleeve 3. This allows the fixing sleeve 3 to drive the connecting rods 42 to rotate, thereby causing the guide plate 41 to rotate. The inclined angle of the guide plate continuously guides the asphalt from the periphery to the center for mixing, improving the mixing efficiency of the asphalt. The guide plate 41 has symmetrical locking grooves 412 at both ends near the side wall. The two connecting rods 42 have adjusting grooves 421 at corresponding positions to the locking grooves 412, and are threaded into the locking grooves 412 by bolts passing through the adjusting grooves 421.
[0025] In use, the angle of the guide plate 41 is first adjusted so that it can move inside the adjustment groove 421, and its position is fixed by bolts connecting to the locking groove 412. This allows the external asphalt to be continuously guided to the center for stirring during use. Then, the drive shaft 1 drives the rotation of multiple spiral blade bodies 2 through the fixing sleeve 3, continuously lifting and turning the internal asphalt. The external guide assembly 4 then guides the turned asphalt from the periphery to the center, thereby achieving circular turning and stirring and improving the overall stirring efficiency.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
