Abstract
Description
Technical Field
[0001] This utility model relates to the field of vertical mixing technology, specifically to a three-dimensional vertical shaft mixer. Background Technology
[0002] A vertical shaft mixer is a device that uses the vertical shaft planetary mixing principle. The planetary mixing device revolves and rotates around the central main shaft, thereby driving the material to move and giving the material a complex and continuous mechanical action, achieving rapid and uniform mixing.
[0003] In some large-scale industrial production environments, materials often need to be efficiently transported from a low-level to a high-level mixing hopper using a auger-type feeding device. These materials flow naturally into the mixing equipment below through the mixing hopper. However, when processing materials with small particle diameters, the materials tend to accumulate inside the mixing hopper, which may cause blockage of the conveying pipe at the bottom of the mixing hopper. Ultimately, this prevents the materials from smoothly entering the mixer, affecting the subsequent production process. Utility Model Content

The top of the multi-stage telescopic rods is connected to the top plate, and springs are sleeved on the surface of the multi-stage telescopic rods. The two ends of the springs are fixedly connected to the top plate and the connecting frame, respectively.
[0010] Furthermore, two multi-stage telescopic rods are symmetrically fixedly connected to the surface of the connecting frame. The top of the multi-stage telescopic rods is connected to the top plate, and springs are sleeved on the surface of the multi-stage telescopic rods. The two ends of the springs are fixedly connected to the top plate and the connecting frame, respectively.
[0011] Furthermore, slots are provided on opposite sides of the inner wall of the rectangular groove, and a limiting strip is slidably connected to the inner wall of the slot, the limiting strip being fixedly connected to one side of the rack.

[0015] 1. This utility model, by setting up a moving mechanism, utilizes a ball and the groove on the ball, and together with a connecting rod, to achieve vertical up-and-down reciprocating movement in the premixing hopper, thereby avoiding the situation where materials easily accumulate inside the mixing hopper, causing blockage of the conveying pipe at the bottom of the mixing hopper, and ultimately preventing the materials from smoothly entering the mixer.

[0026] 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.
[0027] like Figures 1 to 2 As shown, an embodiment of this utility model provides a three-dimensional vertical shaft mixer, including two collection tanks 1. A bucket elevator 2 is provided at the inlet and outlet of the collection tank 1, and an auger feeder 3 for transporting materials is provided at the outlet of the collection tank 1. A pre-mixed hopper 5 is provided at the bottom of the outlet end of the auger feeder 3. An agitator 7 connected to the hopper by a pipe is provided on the hopper. The surfaces of the auger feeder, the pre-mixed hopper 5 and the agitator 7 are fixed to the ground by a receiving platform 4. A moving mechanism 6 for preventing material blockage is provided on the pre-mixed hopper.
[0028] Personnel can use the bucket elevator 2 to transport materials from the ground to the collection tank 1 for storage. At the same time, the materials in the collection tank 1 can be transported to the premixed mixing hopper 5 by the auger feeder, and finally flow into the mixer 7 for mixing. Meanwhile, a climbing ladder is set up on the side of the receiving platform 4, which personnel can use to observe and maintain the equipment.
[0029] More specifically, such as Figures 3 to 6As shown, the moving mechanism 6 includes a rectangular trough 601 formed on the premixed hopper 5. A bottom plate 604 and a top plate 602 are fixedly connected to the rectangular trough 601. A moving plate 603 that can move vertically is provided on the top plate 602 and the bottom plate 604. A connecting frame 606 is fixedly connected to the surface of the moving plate 603. Two multi-stage telescopic rods 605 are symmetrically fixedly connected to the surface of the connecting frame 606. The top of the multi-stage telescopic rods 605 is connected to the top plate 602. A spring is sleeved on the surface of the multi-stage telescopic rods 605. The two ends of the spring are fixedly connected to the top plate 602 and the connecting frame 606, respectively. A rack 607 is fixedly connected to one end of the connecting frame 606. A semi-circular gear 610 meshes with the surface of the rack 607. A stepper motor 609 is fixedly connected to the center position of one side of the semi-circular gear 610. By controlling the stepper motor 609, the semi-circular gear 610 can be moved. The rotation speed is controlled at 0. A rectangular bar 612 is fixedly connected to the side of the moving plate 603 away from the connecting frame 606. A connecting rod 613 is fixedly connected to the rectangular bar 612. A ball 614 is fixedly connected to one end of the connecting rod 613. Under the rotation of the stepper motor 609, the semi-circular gear 610 drives the rack 607, thereby indirectly driving the connecting rod 613 and the ball 614 to move vertically inside the premixed mixing hopper. At the same time, during the rotation of the semi-circular gear 610, there is a period of time when the semi-circular gear 610 is not engaged with the rack 607. During this period, the multi-stage telescopic rod 605 on the moving frame will be subjected to the elastic force of the spring, thereby performing a reset operation. The connecting rod 613 and the ball 614 will have periodic reciprocating motion throughout the process, thereby pushing the material blocked in the pipe of the premixed mixing hopper 5 into the mixer 7.
[0030] Meanwhile, in order to increase the stability of the stepper motor 609 during operation, such as Figure 5 As shown, the outer wall of the stepper motor 609 is connected to the outer arc surface of the premixed material via a fixing bracket 608.
[0031] It should be noted that, for example Figure 6 As shown, the surface of the sphere 614 is uniformly provided with grooves 615, and the length of the connecting rod 613 extends to the bottom of the premixed hopper 5 pipe. The grooves 615 can facilitate the sphere 614 to move vertically and reduce the resistance during movement. At the same time, the grooves 615 can increase the contact area between the sphere and the material, which can increase the effect of pushing the material to a certain extent. In addition, the length of the connecting rod 613 is long enough to better achieve the effect of unblocking the pipe.
[0032] like Figure 7As shown, in order to better increase the stability of the rack 607 and the semi-circular gear 610 during the meshing process, slots 611 are provided on both sides of the inner wall of the rectangular groove 601. The inner wall of the slot 611 is slidably connected to a limiting strip 616, which is fixedly connected to one side of the rack 607.
[0033] To further explain, such as Figure 4 As shown, the base plate 604, the movable plate 603 and the base plate 604 together form a complete arc plate, and the size matches the rectangular groove 601, thereby preventing the material in the premixed mixture hopper from flowing to the outside through the gap.
[0034] In this embodiment of the utility model (working principle), the material is transported to the collection tank 1 for storage by the bucket elevator 2, and then conveyed from low to high to the premixed mixing hopper 5 by the auger feeder 3. The rotation of the stepper motor 609 drives the periodic meshing between the rack 607 and the semi-circular gear 610. With the cooperation of the spring and the multi-stage telescopic rod 605, the ball 614 and the connecting rod 613 as a whole realize the periodic up and down reciprocating motion in the vertical direction.
[0035] 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.
