Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mixing technology, and in particular relates to a mixing device that avoids residual material. Background Technology
[0002] A mixing device generally refers to an operation that uses mechanical methods to disperse two or more materials to achieve a homogeneous state. It is used to accelerate heat transfer, mass transfer, and chemical reactions. It is also used to promote physical changes and produce many mixtures, such as solutions, emulsions, suspensions, and mixtures, which can be carried out in mixers and similar equipment.
[0003] In existing mixing devices, residual material adheres to the inside of the mixing drum during operation, requiring manual scraping by workers, which is a cumbersome process. Therefore, we propose a mixing device that avoids material residue. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned technical problems by providing a mixing device that avoids residual material and enables automatic scraping of residual material inside the mixing device.
[0005] In view of this, the present invention provides a mixing device to avoid residual material, comprising a mixing cylinder, an inlet installed on the outer wall of the mixing cylinder, a discharge port installed at the bottom end of the mixing cylinder, a mixing motor fixedly connected to the top end of the mixing cylinder, a mixing shaft fixedly connected to the output end of the mixing motor, an upper connecting rod welded to the outer wall of the mixing shaft, an upper telescopic rod penetrating through the inner wall of the upper connecting rod, an outer mixing plate welded to one end of the upper telescopic rod, a lower telescopic rod welded to the outer wall of the outer mixing plate, a lower connecting rod welded to the outer wall of the mixing shaft sleeved on the outer wall of the lower telescopic rod, an inner mixing plate welded to the connection part of the upper connecting rod and the lower connecting rod, a cleaning base sleeved on the outside of the mixing shaft fixedly connected to the inner wall of the mixing cylinder, a pneumatic push rod fixedly connected to the outer wall of the cleaning base, a lifting ring fixedly connected to the output end of the pneumatic push rod, a rotating ring fitted at the bottom end of the lifting ring, a support rod hinged to the bottom end of the rotating ring and hinged to the outer wall of the outer mixing plate, and a scraper fixedly connected to the side wall of the outer mixing plate.
[0006] Based on the above structure, the lifting ring slides and drives the rotating ring to slide synchronously. The rotating ring slides through the support rod and drives the upper and lower telescopic rods of the outer wall of the outer mixing plate to slide along the inner walls of the upper and lower connecting rods respectively, so that the outer mixing plate slides and drives the scraper to fit against the inner wall of the mixing cylinder. Then, the mixing motor works and drives the scraper through the mixing shaft to scrape off the residual material attached to the inner wall of the mixing cylinder.
[0007] Preferably, the bottom of the mixing cylinder is inverted conical, and the inner wall of the mixing cylinder is coated with a wear-resistant coating. In this embodiment, by setting the mixing cylinder with an inverted conical bottom, it is beneficial for the material to be discharged from the discharge port by its own gravity.
[0008] Preferably, the upper connecting rod and the lower connecting rod are parallel, and the outer mixing plate is perpendicular to the upper connecting rod and the lower connecting rod. In this embodiment, this helps to improve the stability of the connection of the outer mixing plate and avoid deformation of the outer mixing plate.
[0009] Preferably, the inner mixing plate and the outer mixing plate are parallel. In this embodiment, the rotation of the mixing shaft drives the outer mixing plate to rotate through the upper connecting rod and the lower connecting rod. At the same time, the rotation of the mixing shaft drives the inner mixing plate to rotate synchronously. Through the rotation of the outer mixing plate and the inner mixing plate, the mixture in the mixing cylinder is fully mixed.
[0010] Preferably, the central axes of the lifting ring and the rotating ring coincide. In this embodiment, collisions between the lifting ring and the rotating ring are avoided during material mixing.
[0011] Preferably, the upper telescopic rod forms a telescopic structure with the upper connecting rod through the rotating ring and the support rod. The outer shape of the outer mixing plate is the same as the cross-section of the mixing cylinder. In this embodiment, it is beneficial for the lifting ring to slide synchronously with the rotating ring. The sliding of the rotating ring drives the upper telescopic rod and the lower telescopic rod on the outer wall of the outer mixing plate to slide along the inner wall of the upper connecting rod and the lower connecting rod, respectively, through the support rod.
[0012] Preferably, the scraper has the same shape as the outer mixing plate, and the cross-section of the scraper is triangular. In this embodiment, the outer mixing plate slides to drive the scraper to fit against the inner wall of the mixing cylinder. Then, the mixing motor drives the scraper through the mixing shaft to scrape off the residual material attached to the inner wall of the mixing cylinder.
[0013] The beneficial effects of this utility model are:
[0014] 1. This mixing device, which avoids residual material, is equipped with an outer mixing plate and an inner mixing plate. The mixing motor drives the mixing shaft to rotate, and the rotation of the mixing shaft drives the outer mixing plate to rotate through the upper and lower connecting rods. At the same time, the rotation of the mixing shaft drives the inner mixing plate to rotate synchronously. Through the rotation of the outer and inner mixing plates, the mixture in the mixing cylinder is fully mixed.
[0015] 2. This mixing device, which avoids residual material, is equipped with a scraper. The lifting ring slides and drives the rotating ring to slide synchronously. The rotating ring slides through the support rod and drives the upper and lower telescopic rods on the outer wall of the outer mixing plate to slide along the inner walls of the upper and lower connecting rods, respectively. This causes the outer mixing plate to slide and drive the scraper to fit against the inner wall of the mixing cylinder. Then, the mixing motor works and drives the scraper through the mixing shaft to scrape off the residual material adhering to the inner wall of the mixing cylinder. Attached Figure Description

An upper connecting rod 6 is welded to the outer wall of the mixing shaft 5, and an upper telescopic rod 7 passes through the inner wall of the upper connecting rod 6. An outer mixing plate 8 is welded to one end of the upper telescopic rod 7, and a lower telescopic rod 9 is welded to the outer wall of the outer mixing plate 8. A component that is connected to the mixing shaft 9 is sleeved on the outer wall of the lower telescopic rod 9. The lower connecting rod 10 is welded to the outer wall of the mixing shaft 5. The upper connecting rod 6 and the lower connecting rod 10 are connected to an inner mixing plate 11. The inner wall of the mixing cylinder 1 is fixedly connected to a cleaning base 12 that is sleeved on the outside of the mixing shaft 5. The outer wall of the cleaning base 12 is fixedly connected to a pneumatic push rod 13. The output end of the pneumatic push rod 13 is fixedly connected to a lifting ring 14. The bottom end of the lifting ring 14 is fitted with a rotating ring 15. The bottom end of the rotating ring 15 is hinged to a support rod 16 that is hinged to the outer wall of the outer mixing plate 8. The side wall of the outer mixing plate 8 is fixedly connected to a scraper 17.
[0025] Based on the above structure, the lifting ring 14 slides and drives the rotating ring 15 to slide synchronously. The rotating ring 15 slides through the support rod 16 and drives the upper telescopic rod 7 and lower telescopic rod 9 of the outer wall of the outer mixing plate 8 to slide along the inner wall of the upper connecting rod 6 and the lower connecting rod 10 respectively, so that the outer mixing plate 8 slides and drives the scraper 17 to fit against the inner wall of the mixing cylinder 1. Then, the mixing motor 4 works and drives the scraper 17 through the mixing shaft 5 to scrape off the residual material attached to the inner wall of the mixing cylinder 1.
[0026] In one embodiment, the bottom end of the mixing cylinder 1 is inverted conical, and the inner wall of the mixing cylinder 1 is coated with a wear-resistant coating.
[0027] In this embodiment, by setting the mixing cylinder 1 with an inverted cone shape at the bottom, it is beneficial for the material to be discharged from the discharge port 3 by its own gravity.
[0028] In one embodiment, the upper connecting rod 6 and the lower connecting rod 10 are parallel, and the outer mixing plate 8 is perpendicular to the upper connecting rod 6 and the lower connecting rod 10.
[0029] In this embodiment, it is beneficial to improve the stability of the connection of the outer mixing plate 8 and avoid deformation of the outer mixing plate 8.
[0030] In one embodiment, the inner mixing plate 11 and the outer mixing plate 8 are parallel.
[0031] In this embodiment, the rotation of the mixing shaft 5 drives the outer mixing plate 8 to rotate via the upper connecting rod 6 and the lower connecting rod 10. At the same time, the rotation of the mixing shaft 5 drives the inner mixing plate 11 to rotate synchronously. Through the rotation of the outer mixing plate 8 and the inner mixing plate 11, the mixture in the mixing cylinder 1 is fully mixed.
[0032] In one embodiment, the central axes of the lifting ring 14 and the rotating ring 15 coincide.
[0033] In this embodiment, collisions between the lifting ring 14 and the rotating ring 15 are avoided during material mixing.

[0035] In this embodiment, the sliding of the lifting ring 14 facilitates the synchronous sliding of the rotating ring 15. The sliding of the rotating ring 15, through the support rod 16, causes the upper telescopic rod 7 and the lower telescopic rod 9 on the outer wall of the outer mixing plate 8 to slide along the inner walls of the upper connecting rod 6 and the lower connecting rod 10, respectively.
[0036] In one embodiment, the scraper 17 has the same shape as the outer mixing plate 8, and the cross-section of the scraper 17 is triangular.

Then, the mixing motor 4 works to drive the scraper 17 through the mixing shaft 5 to scrape off the remaining material attached to the inner wall of the mixing cylinder 1.
[0038] In this embodiment, the mixing device that avoids residual material is used in the following steps: First, the operator injects the mixture into the mixing cylinder 1 through the injection port 2. Then, the mixing motor 4 drives the mixing shaft 5 to rotate. The rotation of the mixing shaft 5 drives the outer mixing plate 8 to rotate through the upper connecting rod 6 and the lower connecting rod 10. At the same time, the rotation of the mixing shaft 5 drives the inner mixing plate 11 to rotate synchronously. Through the rotation of the outer mixing plate 8 and the inner mixing plate 11, the mixture in the mixing cylinder 1 is fully mixed.
[0039] Next, the staff opened the valve inside the discharge port 3, and the material was discharged through the discharge port 3.
[0040] Finally, the pneumatic push rod 13 drives the lifting ring 14 to slide vertically along the outer wall of the cleaning base 12. The sliding of the lifting ring 14 drives the rotating ring 15 to slide synchronously. The rotating ring 15 slides through the support rod 16 to drive the upper telescopic rod 7 and the lower telescopic rod 9 of the outer wall of the outer mixing plate 8 to slide along the inner wall of the upper connecting rod 6 and the lower connecting rod 10 respectively, so that the outer mixing plate 8 slides and drives the scraper 17 to fit against the inner wall of the mixing cylinder 1.
