Description

Technical Field

[0001] The utility model relates to the field of powder pipeline cleaning, in particular to a powder material pipe wall cleaning device. Background Art

[0002] In the preparation process of dyes, it is often necessary to transport powder materials. Since many materials in the raw materials, intermediate products and products of dyes are relatively fine powders, closed pipelines are mostly used for transportation. Air flow is used for assistance during upward transportation, and gravity is used for material dropping through a chute when there is no feeding requirement. In the case of not cooperating with air flow transportation, if an inclined chute is used during the powder dropping process, it is very easy for materials to adhere to the lower side of the pipe wall. Especially, the hygroscopicity of dye powder is very high, making it difficult to clean the adhered materials on the pipe wall, resulting in the unevenness of the lower side peripheral surface of the chute inner wall, and even material accumulation, affecting the material dropping and causing maintenance problems. Content of the Utility Model

[0022] The following combines specific embodiments to further elaborate on the present invention. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by this application.

[0023] This device is specifically used for cleaning inclined powder conveying pipelines. The main structure includes a connecting frame. In this example, the connecting frame adopts a "Feng" - shaped structure, which is overall light and concise and not easy to hook and store materials. Specifically, the "Feng" - shaped connecting frame includes a longitudinal beam 1 arranged in the middle and along the length direction of the chute during use. A plurality of cross beams 2 perpendicular to and horizontally extending from the longitudinal beam 1 are provided in the center of the longitudinal beam 1. In this example, 3 cross beams 2 are provided, so it is in the shape of a "Feng", but it is not limited to this example, and multiple or one cross beam can also be used. The center of the cross beam 2 is fixedly connected to the longitudinal beam 1 and integrally formed, and the multiple cross beams 2 are equidistantly arranged.

[0024] A joint seat 3 is provided in the middle of one end of the longitudinal beam 1. A spherical cavity is provided at the end of the joint seat 3 away from the longitudinal beam 1. A ball head 4 is in rolling fit in the spherical cavity. The edge of the spherical cavity is inclined downward, which is convenient for adapting to the swing of the pull rod 14 when the counterweight ball 6 falls. A straight rod 5 is fixed on the ball head 4 in front of the joint seat 3. A counterweight ball 6 is fixed at the end of the straight rod 5 away from the joint seat 3. The counterweight ball 6 can be a smooth - surfaced metal ball, which drives the entire device to fall without power in the chute based on gravity, has a smooth contact with the inner wall of the chute, and does not damage the inner wall of the pipeline.

[0025] A scraper 7 is provided below the cross beam 2. Since 3 cross beams 2 are used in this example, three scrapers 7 arranged along the longitudinal beam 1 direction are provided below the connecting frame. The scraper 7 is an overall downward - arched conical surface. The two ends of the fixed scraper 7 are respectively fixedly connected to the two ends of the cross beam 2. The front side of the scraper 7 close to the joint seat 3 is the front side edge 8, and the rear side far from the joint seat 3 is the rear side edge 9. The front side edge 8 is an arc whose radian is adapted to the circumferential surface of the inner wall of the pipeline, and the rear side edge 9 is an arc coaxial with the front side edge 8 and with a diameter smaller than the inner diameter of the pipeline. Thus, the front side edge 8 of the scraper 7 passes through the bottom side of the pipe wall to realize scraping of the wall - hanging materials, and through the trumpet - shaped conical surface structure of the rear side edge 9 that converges, the scraped powder is scooped forward and pushed, better taking out the scraped materials from the pipeline.

[0026] Through the scraping in front of the triple scraper 7 and the pushing by the scraper 7, the residual powder at the bottom of the inner wall of the passing pipeline can be removed multiple times, thus quickly completing the maintenance of the inner wall cleaning of the pipeline.

[0027] Two hinge shafts 10 are also fixedly penetrated on the longitudinal beam 1. The hinge shafts 10 extend horizontally and are perpendicular to the longitudinal beam 1. The hinge shafts 10 are arranged side by side relative to the cross beam 2. H-shaped wheel frames are respectively hinged on the two hinge shafts 10. The wheel frame includes a top rod 11 and a connecting rod 12. The two ends of the hinge shaft 10 are respectively provided with top rods 11 rotatably connected thereto. The connecting rod 12 is a circular rod, and its two ends are respectively connected to the middle parts of the top rods 11 of the same hinge shaft 10. An H-shaped structure is formed by the top rod 11 and the connecting rod 12. The top end of the top rod 11 is rotatably connected with a pressing wheel 13. The top peripheral surface of the pressing wheel 13 is used for pressing and fitting on the top of the inner wall of the pipeline. A pull rod 14 is arranged between the two groups of wheel frames. The two ends of the pull rod 14 are respectively provided with sleeves 15 rotatably sleeved on the connecting rod 12. The distance between the two sleeves 15 corresponds to the distance between the two hinge shafts 10, so that the two groups of wheel frames form a stable parallelogram support structure through the pull rod 14.

[0028] An elastic member is arranged between the wheel frame and the connecting frame. The elastic member has an elastic force that makes the wheel frame swing upward, so as to tightly press and press on the inner wall of the pipeline, and assist in scraping the residual powder on the inner wall of the pipeline downward more forcefully with the scraper 7.

[0029] Specifically, the elastic member can be a torsion spring. A torsion spring is installed between the hinge shaft 10 and the top rod 11, so that the four top rods 11 respectively have an elastic force to swing upward.

[0030] Specifically, the elastic member can be a tension spring 16. A hanging rod 17 is fixed at the front end of the longitudinal beam 1. The front end of the tension spring 16 is hooked on the hanging rod 17, and the rear end of the tension spring 16 is hooked on the front-side connecting rod 12, so as to pull the wheel frame forward, make it swing upward and realize the cooperation with the peripheral surface of the top wall of the pipeline. This structure is convenient for disassembling the tension spring 16, thus being more beneficial for storage.
