Description

Technical Field

[0001] This utility model relates to a conveying pipe for viscous powdery materials, belonging to the field of conveying technology for viscous powdery materials. Background Technology

[0002] In the field of material conveying, bucket elevators are important equipment widely used for conveying various powdery and granular materials. The main function of this equipment is to vertically lift materials by continuously rotating buckets on a chain. However, in practical applications, especially for conveying fine granular materials such as limestone powder, some common technical challenges exist. Some materials have a certain degree of moisture, leading to particle agglomeration, which is mainly caused by liquid bridging forces.

[0003] For fine particulate materials, especially limestone powder with a particle size of 0.04mm-1mm, traditional bucket elevators typically use vibrators or air-blowing methods in the design of the discharge pipe to promote material descent, thereby reducing material adhesion and accumulation within the discharge pipe, preventing blockage, and achieving macroscopic particle separation. However, vibrators are ineffective for agglomerated, sticky materials and consume a lot of energy; while air-blowing with compressed gas is also ineffective and can easily cause material spillage.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing a conveying pipe for viscous powdery materials. It can unclog pipes, effectively prevent viscous materials from adhering to the inner wall of the pipe, and improve the material flow rate. It can also clean the inner wall of the pipe.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: A conveying pipe for viscous powdery materials includes a discharge pipe, wherein a rotating frame is rotatably installed inside the discharge pipe; The rotating frame includes two parallel angle steels, and multiple connecting rods are connected between the angle steels. The two angle steels and multiple connecting rods are combined to form a four-dimensional frame. Drive shafts extend outward from the middle of the connecting rods at both ends of the rotating frame. An upper connecting pipe is provided at the upper end of the feeding pipe, and a lower connecting pipe is provided at the lower end of the feeding pipe. The drive shafts at both ends of the rotating frame are rotatably mounted on the upper connecting pipe and the lower connecting pipe, respectively. The drive shafts are driven by a drive device.

[0007] Furthermore, the drive shaft is coaxially arranged with the central axis of the feed tube.

[0008] Furthermore, the upper connecting pipe and the lower connecting pipe are set at a certain angle to the feeding pipe, and mounting seats are provided on the pipe walls of both the upper connecting pipe and the lower connecting pipe, and the drive shaft is rotatably mounted on the mounting seats.

[0009] Furthermore, each angle steel is provided with a rotating shaft on its outer side, the rotating shaft being close to and parallel to the angle steel, and a strip brush being provided on the rotating shaft along its length direction.

[0010] Furthermore, extension rods are provided perpendicularly to both ends of the rotating shaft, and the strip brush is fixed to the outer end of the extension rods, causing the strip brush to extend a certain distance outward from the rotating shaft.

[0011] Furthermore, the angle steel is provided with hinge seats at both ends, and the two ends of the angle steel are rotatably mounted on the hinge seats.

[0012] Furthermore, the driving device includes a drive motor, a driving gear, and a driven gear. The driven gear is fixedly installed on the outer end of the drive shaft. The driving gear meshes with the driven gear for transmission, and the drive motor drives the driving gear to rotate.

[0013] Furthermore, a fixing plate is welded to the outside of the feeding pipe, and the drive motor is fixed on the fixing plate.

[0014] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: Driven by the drive device, the rotating frame rotates. The two parallel angle steels of the rotating frame rotate close to the inner wall of the feeding pipe, which plays a role in unblocking the pipe and effectively prevents sticky materials from adhering to the inner wall of the pipe. Moreover, the angle steels increase the flow rate of materials during the rotation process.

[0015] When the rotating frame rotates in the reverse direction, as shown in Figures 1 and 2, the extension rod is blocked on one side of the angle steel, thereby causing the strip brush to extend outward until it contacts the inner wall of the feed pipe. At this time, the strip brush plays a role in cleaning the inner wall of the feed pipe.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0020] like Figure 1-6 As shown, this utility model provides a conveying pipe for viscous powdery materials, including a feeding pipe 1, in which a rotating frame is rotatably installed; The rotating frame includes two parallel angle steels 4, and multiple connecting rods 9 are connected between the angle steels 4. The two angle steels 4 and the multiple connecting rods 9 are combined to form a four-deformation frame. Drive shafts 10 extend outward from the middle position of the connecting rods 9 at both ends of the rotating frame. The upper end of the feeding pipe 1 is provided with an upper connecting pipe 2, and the lower end of the feeding pipe 1 is provided with a lower connecting pipe 3. The drive shafts 10 at both ends of the rotating frame are rotatably mounted on the upper connecting pipe 2 and the lower connecting pipe 3, respectively. The drive shafts 10 are driven by a drive device.

[0021] The drive shaft 10 is coaxial with the central axis of the feed tube 1.

[0022] The upper connecting pipe 2 and the lower connecting pipe 3 are set at a certain angle to the feeding pipe 1, and each of the upper connecting pipe 2 and the lower connecting pipe 3 is provided with a mounting seat 11. The drive shaft 10 is rotatably mounted on the mounting seat 11.

[0023] Each angle steel 4 has a rotating shaft 5 on its outer side. The rotating shaft 5 is close to and parallel to the angle steel 4. A strip brush 8 is provided on the rotating shaft 5 along its length direction.

[0024] Extension rods 6 are provided perpendicularly to both ends of the rotating shaft 5, and the strip brush 8 is fixed to the outer end of the extension rods 6, so that the strip brush 8 extends a certain distance outward from the rotating shaft 5.

[0025] The angle steel 4 has hinge seats 7 at both ends, and the two ends of the angle steel 4 are rotatably mounted on the hinge seats 7.

[0026] The driving device includes a drive motor 14, a driving gear 13 and a driven gear 12. The driven gear 12 is fixedly installed on the outer end of the drive shaft 10. The driving gear 13 meshes with the driven gear 12 for transmission. The drive motor 14 drives the driving gear 13 to rotate.

[0027] A fixing plate 15 is welded to the outside of the feeding pipe 1, and the drive motor 14 is fixed on the fixing plate 15.

[0028] The specific working principle of this utility model: The rotating frame rotates under the drive of the drive device. The two parallel angle steels 4 of the rotating frame rotate close to the inner wall of the feed pipe 1, which plays a role in unblocking the pipe and effectively prevents sticky materials from adhering to the inner wall of the pipe. Moreover, the angle steels 4 increase the flow rate of materials during the rotation process.

[0029] Angle steel 4 has a rotating shaft 5 hinged to its outer side. The shaft 5 is connected to the strip brush 8 via an extension rod 6. The drive device can rotate the rotating frame in both directions. When rotating in the forward direction, as... Figure 6 As shown, the extension rod 6 detaches from the angle steel 4, allowing the strip brush 8 to work together with the angle steel 4 to convey materials; when rotating in the reverse direction, as... Figure 4 and Figure 5 As shown, the extension rod 6 is blocked on one side of the angle steel 4, so that the strip brush 8 extends outward to contact the inner wall of the feed pipe 1. At this time, the strip brush 8 plays a role in cleaning the inner wall of the feed pipe 1.
