Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a multi-stage continuous mixing device. Background Technology

[0002] Mixing equipment is a type of general-purpose mechanical equipment that drives mixing components (such as stirring paddles, agitators, etc.) to rotate or reciprocate within a container, causing physical or chemical processes such as forced convection, mixing, dispersion, suspension, emulsification, or reaction of materials. It is widely used in industrial and civilian fields such as chemical, food, pharmaceutical, and water treatment. Its core function is to change the physical state of materials or promote the interaction between substances through mechanical energy transfer, so as to meet the requirements of material uniformity, reaction efficiency, etc. in the production process.

[0003] For example, the Chinese authorized patent CN222096608U, entitled "A Mixing Device," includes a mixing tank. The mixing tank is mounted on a support base, and its two ends are rotatably connected to the shaft seats on the support base via rotating shafts. A belt drive device is provided on one side of the outer periphery of the mixing tank on the support base, and a groove is formed around the other side of the mixing tank along its outer edge. The belt drive device drives the mixing tank to rotate in the forward direction, while the motor drives the rotating shaft in the opposite direction to the rotation of the mixing tank. While the mixing tank mixes the plastic particles inside, the plastic particles will sway at the bottom due to their weight.

[0004] While the existing technologies mentioned above can achieve the mixing and stirring of materials, they require the raw materials and auxiliary materials to be mixed in batches. If large-scale production is required, the only option is to increase the size of the mixing equipment or purchase multiple mixing equipment, which not only increases the equipment cost but also requires a lot of manpower. Therefore, they do not meet the current needs. In response, we propose a multi-stage continuous mixing equipment. Utility Model Content

[0005] The purpose of this invention is to provide a multi-stage continuous mixing device to solve the problem mentioned in the background art of how the mixing device can meet the requirements of mass production while ensuring the mixing effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage continuous mixing device, including a base, a horizontally arranged primary mixing mechanism fixedly installed on the top of the base, a feed cylinder at the front end of the primary mixing mechanism for adding the main raw materials, a premixing cylinder connected to the primary mixing mechanism at the rear end of the feed cylinder for mixing other auxiliary materials, a longitudinally distributed secondary mixing mechanism at the rear end of the upper surface of the base, a conveying pipe connecting the two sides of the end of the primary mixing mechanism to the two sides of the upper surface of the secondary mixing mechanism, a symmetrical mixing conveying mechanism inside the secondary mixing mechanism, and a discharge pipe at the middle position of the bottom of the secondary mixing mechanism.

[0007] Preferably, a first rotating shaft is rotatably mounted inside the primary mixing mechanism, and a plurality of equidistantly distributed first helical blades are provided on the outer wall of the first rotating shaft. A first motor for driving the first rotating shaft to rotate is fixedly provided at the front end of the primary mixing mechanism.

[0008] Preferably, a detachable top cover is installed at the upper end of the premixing cylinder, a second motor is fixedly installed at the top of the top cover, a central gear connected to the output shaft of the second motor is provided at the middle position of the inner cavity of the top cover, three planetary gears are provided around the central gear and mesh with the central gear, a toothed ring is provided on the wall of the inner cavity of the top cover and meshes with the planetary gears, and a stirring rod extending into the interior of the premixing cylinder is provided at the bottom of both the central gear and the planetary gears.

[0009] Preferably, the mixing and conveying mechanism includes a second rotating shaft, one end of which is rotatably connected to the secondary mixing mechanism, and the other ends of the second rotating shaft are connected to each other through a bearing joint, and the bearing joint is fixed to the secondary mixing mechanism. The outer side of the second rotating shaft is provided with a plurality of equidistantly distributed second spiral blades.

[0010] Preferably, a feeding trough is provided at the middle position of the bottom surface of the secondary mixing mechanism, and the feeding trough is connected to the discharge pipe.

[0011] Preferably, a material injection cylinder is installed on both sides of the front end face of the secondary mixing mechanism, a cylinder is installed at the front end of each material injection cylinder, and a feeding pipe is provided above the material injection cylinder.

[0012] Preferably, an electrically controlled flow valve is installed on the pipeline between the premixing cylinder and the primary mixing mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the cooperation of a primary mixing mechanism and a secondary mixing mechanism, can achieve continuous stirring and mixing of materials. The materials and some auxiliary materials are initially mixed in the primary mixing mechanism. After mixing, they enter the secondary mixing mechanism through conveying pipes on both sides of the end of the primary mixing mechanism. The secondary mixing mechanism can move the materials entering through the conveying pipes from both sides of the inner cavity towards the center position. During the movement, the materials are further mixed. At the same time, when the materials move to the center, the materials on both sides squeeze and collide with each other, achieving efficient mixing between different materials. Finally, the materials are discharged from the discharge chute at the center of the bottom of the secondary mixing mechanism for collection by the staff.

[0015] 2. This utility model incorporates a multi-directional stirring structure within a premixing cylinder above the primary mixing mechanism. By activating a second motor, the central gear rotates. The central gear is externally meshed with three ring-shaped planetary gears. These planetary gears mesh with the gear ring of the upper cover. As the central gear rotates, the planetary gears, while revolving around the central gear, maintain their own rotation. This causes the stirring rod below to perform complex movements within the premixing cylinder, ensuring rapid mixing of the auxiliary materials. This results in good uniformity of the materials before they enter the primary mixing mechanism, laying a solid foundation for continuous and efficient mixing in the subsequent primary and secondary mixing mechanisms. Simultaneously, it ensures thorough blending between different auxiliary materials, preventing inconsistent product quality due to uneven mixing.

[0016] 3. This utility model installs injection cylinders on both sides of the front end of the secondary mixing mechanism. The operator adds other raw materials to the internal part in advance through the feeding pipe. After the raw materials from the primary mixing mechanism enter the secondary mixing mechanism through the conveying pipe, the cylinder is opened, and the piston at the movable end injects other raw materials from the injection cylinder into the secondary mixing mechanism. This ensures that different raw materials participate in the mixing at the most appropriate stage, avoiding reaction deviations or uneven mixing that may be caused by early mixing. It also allows for flexible adjustment of the timing and amount of addition according to actual production needs, realizing dynamic and precise mixing operation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 An embodiment of this utility model provides a multi-stage continuous mixing device, including a base 1. A horizontally arranged primary mixing mechanism 2 is fixedly installed on the top of the base 1. A feed cylinder 4 is provided at the front end of the primary mixing mechanism 2 for adding the main raw materials. A premixing cylinder 5 connected to the primary mixing mechanism 2 is provided at the rear end of the feed cylinder 4 for mixing other auxiliary materials. An electrically controlled flow valve is installed on the pipe between the premixing cylinder 5 and the primary mixing mechanism 2. A longitudinally distributed secondary mixing mechanism 8 is provided at the rear end of the upper surface of the base 1. The two sides of the end of the primary mixing mechanism 2 are connected to the two sides of the upper surface of the secondary mixing mechanism 8 through a conveying pipe 7. A mixing conveying mechanism is symmetrically arranged inside the secondary mixing mechanism 8. A discharge pipe 10 is provided at the middle position of the bottom of the secondary mixing mechanism 8.

[0024] The main raw material enters through the feed cylinder 4. The flow rate of the pre-mixed auxiliary materials in the premixing cylinder 5 into the primary mixing mechanism 2 is controlled by the electrically controlled flow valve. The two materials are initially mixed in the primary mixing mechanism 2, and then enter the secondary mixing mechanism 8 through the conveying pipe 7. Under the action of the mixing and conveying mechanism, they are further mixed, and finally discharged from the discharge pipe 10. This achieves staged mixing of raw materials and auxiliary materials. The electrically controlled flow valve ensures precise control of the amount of auxiliary materials added. The multi-stage mixing mode improves the mixing uniformity, enhances the stirring efficiency and product quality, and the equipment layout is reasonable.

[0025] Please see Figure 1 and Figure 2 The first-stage mixing mechanism 2 has a first rotating shaft 18 rotatably mounted inside. The outer wall of the first rotating shaft 18 is provided with a plurality of first spiral blades 19 distributed at equal intervals. The front end of the first-stage mixing mechanism 2 is fixedly provided with a first motor 3 for driving the first rotating shaft 18 to rotate.

[0026] After the first motor 3 starts, it drives the first rotating shaft 18 to rotate. The first spiral blade 19 on the first rotating shaft 18 rotates accordingly, stirring the main raw materials and auxiliary materials entering the first-stage mixing mechanism 2 and pushing the materials to the end of the first-stage mixing mechanism 2 to achieve preliminary mixing. The continuous stirring and pushing action of the first spiral blade 19 enables the materials to be quickly and evenly mixed in the first-stage mixing mechanism 2, laying the foundation for subsequent second-stage mixing and improving the efficiency of the overall mixing process.

[0027] Please see Figure 2 The upper end of the premixing cylinder 5 is equipped with a detachable top cover 14. The top of the top cover 14 is fixedly installed with a second motor 6. The middle position of the inner cavity of the top cover 14 is provided with a central gear 15 connected to the output shaft of the second motor 6. The outer side of the central gear 15 is provided with three ring-shaped planetary gears 16, and the planetary gears 16 are meshed with the central gear 15. The inner wall of the top cover 14 is provided with a toothed ring that meshes with the planetary gears 16. The bottom of the central gear 15 and the planetary gears 16 are both provided with stirring rods 17 that extend into the interior of the premixing cylinder 5.

[0028] The second motor 6 is activated, driving the central gear 15 to rotate. The central gear 15 meshes with the planetary gear 16, which in turn meshes with the gear ring of the inner wall of the upper cover 14. This causes the central gear 15 to rotate while the planetary gear 16 revolves around it and maintains its own rotation. This, in turn, drives the bottom stirring rod 17 to perform a complex trajectory movement within the premixing cylinder 5, rapidly mixing the auxiliary materials. This breaks through the limitations of traditional unidirectional stirring. Through the complex movement trajectory of the stirring rod 17, the auxiliary materials can be quickly and thoroughly mixed, achieving good uniformity before entering the primary mixing mechanism 2. This improves the initial mixing quality of the entire mixing process and reduces the pressure of subsequent mixing.

[0029] Please see Figure 3 The mixing and conveying mechanism includes a second rotating shaft 20. One end of the second rotating shaft 20 is rotatably connected to the secondary mixing mechanism 8. The other ends of the second rotating shaft 20 are connected through a bearing joint, and the bearing joint is fixed to the secondary mixing mechanism 8. Multiple equally spaced second spiral blades 21 are provided on the outside of the second rotating shaft 20. A feeding trough 22 is provided at the middle position of the bottom surface of the secondary mixing mechanism 8, and the feeding trough 22 is connected to the discharge pipe 10.

[0030] The second rotating shaft 20 rotates under power drive, and the second spiral blades 21 on it convey the material entering the secondary mixing mechanism 8 from the conveying pipe 7 from both sides towards the center. During the conveying process, the material is further stirred and mixed. When the material moves to the center, the material on both sides squeezes and collides with each other, and finally is discharged from the discharge pipe 10 through the discharge chute 22. The mixing and conveying mechanism realizes the directional movement and deep mixing of the material from both sides towards the center in the secondary mixing mechanism 8. The squeezing and collision between the materials further enhances the mixing effect, ensures the uniformity and fullness of the material mixing, improves the product quality, and the design of the discharge chute 22 and the discharge pipe 10 facilitates the smooth discharge and collection of the material.

[0031] Please see Figure 1 and Figure 4 The secondary mixing mechanism 8 has two injection cylinders 11 installed on both sides of its front end. Each injection cylinder 11 has a cylinder 12 installed at its front end. A feeding pipe 13 is located above the injection cylinder 11. Operators pre-fill other raw materials into the injection cylinder 11 through the feeding pipe 13. When the raw material from the primary mixing mechanism 2 enters the secondary mixing mechanism 8 through the conveying pipe 7, the cylinder 12 is activated. The piston at the moving end of the cylinder 12 injects other raw materials from the injection cylinder 11 into the secondary mixing mechanism 8, mixing them with the already-entered material. The design of the injection cylinder 11 in conjunction with the cylinder 12 enables flexible storage and precise addition of other raw materials. It allows for control of the timing and amount of addition according to production needs, ensuring that different raw materials participate in mixing at the most appropriate stage and avoiding potential problems in the early stages of mixing.

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.
