Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically to a dual-rotor mixer. Background Technology

[0002] A twin-rotor mixer is a device used for mixing, stirring and dispersing materials. It mainly consists of two rotors, a mixing container, a drive unit and a control system.

[0003] However, when using existing dual-rotor mixers to mix raw materials, due to differences in the moisture content and viscosity of the raw materials, the inner wall of the mixer is prone to accumulating and hardening after long-term operation, resulting in resource waste. For example, when processing straw, the straw usually contains a certain amount of moisture. The straw after crushing and mixing has a certain stickiness and is very likely to accumulate and harden on the inner wall. In addition, the hardened raw material may fall off at any time and may contaminate the raw material for the next round of mixing.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0031] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0032] like Figures 1 to 4 As shown, an embodiment of this utility model provides a dual-rotor mixer, comprising:

[0033] The first rotating shaft 101 has two parts, with a transmission belt 102 sleeved on its outer surface. The end of the transmission belt 102 away from the first rotating shaft 101 is inserted into the second rotating shaft 103. The end of the second rotating shaft 103 away from the transmission belt 102 is fixedly connected to the first gear 104. The second gear 105 is meshed at the root of the first gear 104.

[0034] A threaded rod 106 has one end fixedly connected to a gear 104, and a support plate 107 is sleeved on the outer surface of the other end. A housing 108 is fixedly connected to the outer surface of the support plate 107.

[0035] The threaded rod 109 has a sliding block 110 slidably connected to its outer surface. An electric telescopic rod 111 is fixedly connected to the top of the sliding block 110. A flat plate 112 is fixedly connected to the top of the electric telescopic rod 111. A scraper 113 is fixedly connected to the side of the flat plate 112 near the housing 108. A U-shaped rod 114 is fixedly connected to the bottom of the flat plate 112 at its center. A rotating bar 115 is sleeved on the outer surface of the U-shaped rod 114. One end of the rotating bar 115 is rotatably connected to the sliding block 110, and the other end of the rotating bar 115 is rotatably connected to the sliding block 116.

[0036] In this embodiment of the present invention, when stirring the raw materials, the starting motor 201 drives the rotating shaft 101 to rotate, which drives the transmission belt 102 to drive the rotating shaft 103 to rotate, which drives the gear 104 and gear 105 to rotate in opposite directions at the same time, which drives the two threaded rods to rotate in opposite directions, which drives the slider 110 to slide along the threaded rod 109, and drives the scraper 113 to slide along the inner wall of the shell 108, scraping the raw materials that are hardened on the inner wall. When the slider 110 slides to the other end of the threaded rod 109, the electric telescopic rod 111 is started to drive the slider 110 to rise. Due to the restriction of the U-shaped rod 114, while the slider 110 rises, the slider 116 descends to the surface of the threaded rod 106. Since the two threaded rods rotate in opposite directions, the slider 116 slides back to its original position with the threaded rod 106, realizing the scraper 113 reciprocating scraping.

[0037] The two threaded rods are supported by a support plate 107 on the outer surface of the housing 108 and rotate within the support plate 107 to prevent unstable rotation. The extension and retraction of the electric telescopic rod 111 are remotely controlled by digital electrical signals. The start-up time interval is the same each time to ensure that the scraper 113 moves along the same trajectory. The remote control by digital electrical signals is existing technology and will not be explained in detail. Regarding the alternating sliding of slider one 116 and slider two 110, each time slider two 110 rises, slider one 116 falls. The thread at the bottom of slider one 116 is consistent with the threaded rod one 106. This can be achieved through installation and debugging and is existing technology, so it will not be explained in detail.

[0038] like Figures 1 to 4 As shown, one end of one of the two rotating shafts 101 is fixedly connected to the output shaft of motor 201, and the other end is fixedly connected to gear 3 202. The end of the other rotating shaft 101 is fixedly connected to gear 4 203, and gear 3 202 meshes at the root of gear 4 203.

[0039] In this embodiment of the utility model, when stirring the raw materials, the starting motor 201 drives the rotating shaft 101 to rotate, which drives the gear 3 202 and gear 4 203 to rotate in the opposite direction at the same time, which drives the stirring shaft 1 301 and stirring shaft 2 302 to rotate in the opposite direction at the same time, stirring and mixing the raw materials and pushing them. The stirred raw materials are pushed to the discharge port at the bottom of the shell 108, completing the stirring.

[0040] In particular, the raw materials are prone to caking during axial flow, accumulating on the inner wall of the shell 108 and affecting the mixing effect in the next round. The scraper 113 mentioned above can largely avoid this problem by cleaning the inner wall.

[0041] like Figures 1 to 4 As shown, a stirring shaft 301 is fixedly connected to the side of gear 3 202 away from motor 201, and a stirring shaft 302 is fixedly connected to the side of gear 4 203 away from motor 201. The ends of stirring shaft 301 and stirring shaft 302 are rotatably connected to housing 108.

[0042] In this embodiment of the utility model, when stirring the raw materials, the starting motor 201 drives the rotating shaft 101 to rotate, which drives the gear 3 202 and gear 4 203 to rotate in the opposite direction at the same time, which drives the stirring shaft 1 301 and stirring shaft 2 302 to rotate in the opposite direction at the same time, so as to stir, mix and push the raw materials.

[0043] The stirring shaft has several blades installed on its surface. The shape and installation angle of the blades allow the raw material to flow axially within the shell 108. As the raw material flows, it is sheared, which enhances the mixing.

[0044] like Figures 1 to 4 As shown, a groove 401 is provided on the top of the housing 108, a sliding block 402 is slidably connected to the inner wall of the groove 401, and a scraper 113 is fixedly connected to the top of the sliding block 402.

[0045] In this embodiment of the utility model, when cleaning by scraping with the scraper 113, the scraper 113 moves with the sliding block 402 and the plate 112, causing the sliding block 402 to slide in the groove 401, restricting the sliding block 402 to slide horizontally along the threaded rod, so that it will not rotate with the rotation of the threaded rod. At the same time, the sliding block 402 is embedded in the top of the housing 108, providing partial support for the scraper 113 and the like, so that it slides smoothly.

[0046] like Figures 1 to 4 As shown, the scraper 113 is provided in two places, and several protrusions 501 are fixedly connected to its outer surface.

[0047] In this embodiment of the present invention, when cleaning by scraping with scraper 113, although most of the agglomerated raw materials are broken up by the shearing force brought by the blades during the axial flow, some still flow to the edge of the shell 108. When scraper 113 scrapes along the inner wall of shell 108, it collides with the agglomerated raw materials in the opposite direction, breaking up some of the agglomerated raw materials and helping to mix them evenly.

[0048] The scraper 113 is installed on the inner walls of both sides of the housing 108 to continuously clean the areas where raw materials are most likely to accumulate.

[0049] like Figures 1 to 4As shown, a protective cover 601 is fixedly connected to the outer surface of the housing 108 near the motor 201, and a protective cover 602 is fixedly connected to the outer surface of the housing 108 near the gear 104.

[0050] In this embodiment of the invention, when the mixer is working, the top of the housing 108 is open to facilitate material feeding. When mixing drier raw materials, dust will continuously fly out. For the precision transmission motor 201, gears and transmission belt 102, etc., protective covers are needed to prevent dust and reduce the frequency of failure.

[0051] like Figures 1 to 4 As shown, the scraper 113 is L-shaped, and its surface is in contact with the inner wall of the housing 108.

[0052] In this embodiment of the utility model, when cleaning by scraping with the scraper 113, the shape of the scraper 113 fits against the inner wall of the housing 108, ensuring thorough scraping and uniform mixing of the raw materials.

[0053] like Figures 1 to 4 As shown, threaded rod 106 and threaded rod 209 are placed on the same horizontal line.

[0054] In this embodiment of the utility model, when cleaning by scraping with the scraper 113, slider 116 and slider 210 slide alternately on the threaded rod. The extension and retraction distance of the electric telescopic rod 111 is adjusted and fixed in advance. Then, slider 116 and slider 210 rise and fall to the same height each time. This method requires the two threaded rods to be on the same horizontal line, so as to ensure that the rotation of the threaded rod drives the sliding block 402 to slide smoothly and accurately.

[0055] Working principle: The starting motor 201 drives the rotating shaft 101 to rotate, which drives the transmission belt 102 to rotate the rotating shaft 103. This drives the gears 104 and 105 to rotate in opposite directions, which in turn drives the two threaded rods to rotate in opposite directions. This causes the slider 110 to slide along the threaded rod 109, and the scraper 113 to slide along the inner wall of the housing 108, scraping the hardened material on the inner wall. When the slider 110 slides to the other end of the threaded rod 109, the electric telescopic rod 111 is activated to raise the slider 110. Due to the restriction of the U-shaped rod 114, as the slider 110 rises, the slider 116 descends to the surface of the threaded rod 106. Because the two threaded rods rotate in opposite directions, the slider 116 slides back to its original position with the threaded rod 106, thus achieving the reciprocating scraping and cleaning by the scraper 113.

[0056] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
