Description

Technical Field

[0001] This utility model relates to the field of V-type mixer technology, specifically a volumetric mixing device with a guide flow diversion structure. Background Technology

[0002] A V-type mixer is a commonly used material mixing equipment. It consists of two cylinders that are connected at an incline in a V-shape. The cylinder can rotate around a horizontal axis. During operation, the material is loaded into the V-shaped barrel and lifted to a high position as the barrel rotates. Then, it falls to the lowest point of the V by gravity. Mixing is achieved through repeated splitting, merging, and flipping.

[0003] A search revealed Chinese patent CN222489775U, which discloses a V-type mixer for producing mixed feed additives. The mixer includes a support frame with a main control box mounted on its left side. The bottom end of the main shaft penetrates a corresponding position in the top plate, and a tilting frame is connected to the bottom end of the main shaft. Rotating shafts are inserted into the lower inner side of the tilting frame. A V-type mixing drum is installed inside the rotating shaft, and an active bevel gear is sleeved on the outside of the rotating shaft. A pulley is coaxially connected to the left end of both the connecting shaft and the rotating shaft. This V-type mixer for producing mixed feed additives uses a first motor to drive the rotation of the main shaft, which in turn causes the tilting frame to rotate. Simultaneously, the active bevel gear drives the rotation of the driven bevel gear, which in turn drives the rotation of the pulley via the connecting shaft. This increases the centrifugal force for mixing the feed additives inside the V-type mixing drum, preventing material agglomeration caused by simple up-and-down tumbling.

[0004] The above-mentioned device uses centrifugal force to mix the materials inside the mixing device, reducing the agglomeration of materials inside the mixing device. However, when the materials in the V-shaped mixing drum are mixed, the materials fall from the top to the bottom. The materials in the two mixing drums fall and impact each other under the action of the inclined plane. Some materials will be carried to the other side chamber as the drum rotates, but more materials are prone to forming a "pile-slide" cycle at the lowest point. In particular, materials with higher density are prone to local stagnation at the intersection angle, resulting in low efficiency and poor uniformity of materials entering from both sides. At this time, most materials repeatedly enter the original chamber.

[0005] To address this, we propose a volumetric mixing device with a guided flow splitting structure. Summary of the Invention

[0006] The purpose of this invention is to provide a volumetric mixing device with a guiding and diverting structure to solve the problems raised in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a volumetric mixing device with a guiding and diverting structure, including a control box, a rotating shaft connected inside the control box, a mixing tank fixedly installed on the outer surface of the rotating shaft, and a sealing cap detachably connected to one end of the mixing tank;

[0008] The mixing tank is rotatably connected to a fixed shaft inside, and a rotating ring is rotatably connected to the outside of the fixed shaft. A flow divider is fixedly installed on the outer surface of the rotating ring, and a partition is fixedly installed on the inner wall of the mixing tank.

[0009] The sealing cover is rotatably connected to an installation shaft, and a stirring rod is fixedly installed on the outer surface of the installation shaft. A barrier plate is fixedly installed on the inner wall of the mixing tank.

[0010] Preferably, the rotating rings are symmetrically arranged outside the fixed shaft, one end of the diverter plate is in contact with the inner wall of the mixing tank, and a bottom plate is fixedly installed on the inner wall of the mixing tank.

[0011] Preferably, multiple sets of the diverting plates are provided inside the mixing tank, and the multiple sets of diverting plates are arranged in opposite directions and staggered inside the mixing tank, and the width of the diverting plates is smaller than the radius of the mixing tank.

[0012] Preferably, a mounting bracket is fixedly installed on the inner wall of the mixing tank, a pin is rotatably connected inside the mounting bracket, and a fixing rod is rotatably connected to the outer surface of the pin.

[0013] Preferably, a second mounting bracket is fixedly installed on the outer surface of the diverter plate, and a second fixing rod is hinged inside the second mounting bracket. The outer surface of the second fixing rod is slidably connected to the inner wall of the first fixing rod.

[0014] Preferably, a spring is fixedly installed on the inner wall of the first fixing rod, and the other end of the spring is fixedly installed on the outer surface of the second fixing rod.

[0015] Preferably, the partition is located below the rotating ring, and the partition is arranged coaxially with the diverter plate.

[0016] Preferably, a drive motor is installed on the outside of the sealing cover, the output end of the drive motor is connected to one end of the mounting shaft, and the outer surface of the stirring rod is slidably connected to the outer surface of the barrier plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application utilizes the cooperation between the diverter plate and the fixed shaft. The diverter plate can rotate outside the fixed shaft. When the mixing tank is placed upright, the diverter plate contacts the inner wall of the mixing tank. At this time, under the action of gravity, part of the material inside enters the bottom side through the guide plate, and the material on the other side will enter the other side. When the mixing tank is inverted, the materials on both sides will enter different mixing tanks respectively, which can make the materials cross-mix and realize the function of diverting and guiding the internal materials of the mixing tank. This is beneficial to improving the stability of the material circulating on both sides of the mixing tank.

[0019] 2. This application incorporates components such as springs and stirring rods. The springs can push the fixed rod to move. When the mixing tank is placed upright, the springs push the diversion plate to fit against the inner wall of the mixing tank. When the mixing tank is inverted, the diversion plate will disengage from the mixing tank. At this time, the material on one side can flow into one end of the mixing tank below the diversion plate. When the mixing tank is placed upright, the material enters the bottom of the mixing tank. At this time, the stirring rod rotates to stir the material while simultaneously using the tangential contact between the stirring rod and the baffle plate to chop the material, reducing material agglomeration.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a volumetric mixing device with a guiding and diverting structure. Example

[0028] Please see Figure 1 , Figure 2 The system includes a control box 1, with a rotating shaft 2 connected inside the control box 1. A mixing tank 3 is fixedly installed on the outer surface of the rotating shaft 2. A sealing cover 4 is detachably connected to one end of the mixing tank 3. The control box 1 is equipped with a speed-changing structure and a power structure. A protective handle is installed on the outside of the control box 1. The mixing tank 3 has a V-shaped structure and long mixing and storage spaces on both sides. The materials can be fully mixed inside the long storage spaces. Multiple sets of sealing covers 4 are installed on the outside of the mixing tank 3. The sealing covers 4 can be used to quickly feed materials into the mixing tank 3.

[0029] Please see Figure 1 , Figure 2A fixed shaft 5 is rotatably connected inside the mixing tank 3. A rotating ring 6 is rotatably connected outside the fixed shaft 5. A flow divider 7 is fixedly installed on the outer surface of the rotating ring 6. Multiple sets of flow dividers 7 are arranged inside the mixing tank 3, and these multiple sets of flow dividers 7 are arranged in opposite directions and staggered. The width of the flow divider 7 is smaller than the radius of the mixing tank 3. A baffle 8 is fixedly installed on the inner wall of the mixing tank 3. The baffle 8 is located below the rotating ring 6 and is arranged coaxially with the flow divider 7. The rotating ring 6 is symmetrically arranged outside the fixed shaft 5. One end of the flow divider 7 is in contact with the inner wall of the mixing tank 3. A bottom plate 12 is fixedly installed on the inner wall of the mixing tank 3. The bottom plate 12 is located above the flow divider 7. The flow divider 7 and the bottom plate 12 guide the material inside the mixing tank 3 on both sides. Some materials flow under the guidance of the diversion plate 7, while others flow normally under the action of the bottom plate 12. The contact position between the bottom plate 12 and the inside of the mixing tank 3 is set to be inclined towards the middle. Therefore, when the mixing tank 3 is inverted, the materials inside are not easy to settle in the angle of the bottom plate 12. The overall mixing tank 3 has a Y-shaped structure. Under the action of the diversion plate 7, some materials enter the vertical space at the bottom. Since the bottoms of the two diversion plates 7 are oriented to intersect each other, the materials will cross into one side of the space when flowing. Then, when the mixing tank 3 is inverted, the materials in the bottom space enter the mixing area of ​​the space below the diversion plate 7, guiding the materials from one side of the chamber to the other side, realizing the cross-dispersion of the materials, which is beneficial to improving the uniformity of mixing. Example

[0030] Please see Figure 3 , Figure 4 An installation bracket 13 is fixedly installed on the inner wall of the mixing tank 3. A pin 14 is rotatably connected inside the installation bracket 13. A fixing rod 15 is rotatably connected to the outer surface of the pin 14. An installation bracket 2 16 is fixedly installed on the outer surface of the diversion plate 7. A fixing rod 2 17 is hinged inside the installation bracket 2 16. The outer surface of the fixing rod 2 17 is slidably connected to the inner wall of the fixing rod 15. The fixing rod 15 and the fixing rod 2 17 can guide the rotation of the diversion plate 7. The installation bracket 13 and the installation bracket 2 16 have a large internal space. The fixing rod 15 and the fixing rod 2 17 can rotate inside the installation bracket 13 and the installation bracket 2 16. At this time, the fixing rod 15 and the fixing rod 2 17 are relatively wide from the inner walls on both sides. Therefore, the material is not easy to accumulate inside the installation bracket 13 and the installation bracket 2 16, reducing the residue of the internal material.

[0031] A spring 18 is fixedly installed on the inner wall of the fixing rod 15. The other end of the spring 18 is fixedly installed on the outer surface of the fixing rod 17. The diverter plate 7 is made of stainless steel. When the mixing tank 3 is upright, the spring 18 pushes and the gravity of the diverter plate 7 controls the diverter plate 7 to stick to the inner wall of the mixing tank 3. At this time, when the material flows in the forward direction, it can enter the bottom of the mixing tank 3 from top to bottom. The spring 18 can increase the stability of the diverter plate 7 when it rotates, and prevent the material from causing rotational obstruction to the diverter plate 7 when it is deposited inside the mounting frame 13 and the mounting frame 16. Example

[0032] Please see Figure 5 The sealing cover 4 is rotatably connected to the mounting shaft 9. The outer surface of the mounting shaft 9 is fixedly mounted with a stirring rod 10. The inner wall of the mixing tank 3 is fixedly mounted with a barrier plate 11. The outer side of the sealing cover 4 is mounted with a drive motor 19. The output end of the drive motor 19 is connected to one end of the mounting shaft 9. The outer surface of the stirring rod 10 is slidably connected with the outer surface of the barrier plate 11. When the mixing tank 3 is placed upright, the material can enter the bottom space. The drive motor 19 can be a product with its own battery. The rotation of the stirring rod 10 can stir and mix the material entering the bottom space. The tangency between the stirring rod 10 and the barrier plate 11 can break up the material inside the space, reduce the adhesion of the internal material, and improve the stability during mixing.

[0033] Working principle: When the mixing tank 3 is upright, the spring 18 pushes the diversion plate 7 to fit against the inner wall of the mixing tank 3. At this time, a part of the material is guided by the diversion plate 7 into the space on the other side of the bottom. The internal stirring rod 10 and the baffle plate 11 can stir, mix and crush the material at the bottom. Then the mixing tank 3 is inverted. At this time, the material inside falls from the bottom space into the two ends space. The diversion plate 7 rotates under the action of gravity. At this time, the material at the bottom can enter the space on the other side, realizing the cross movement of the material and making the mixing more uniform.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
