AI Technical Summary
[0003]现有的混合机,在实际应用中存在明显不足:一方面,仅依赖筒体旋转的被动混合方式,物料间碰撞、剪切作用较弱,易导致团聚或分层,尤其在处理粘性或细粉物料时,混合均匀度难以满足高精度需求;另一方面,部分改进型设备虽通过增设独立驱动的搅拌部件(如搅拌桨、螺旋杆)提升混合效果,但需额外电机、传动机构等动力系统,不仅增加了设备复杂度与维护成本,还导致整体能耗上升,不符合绿色制造趋势
[0017] This invention features a stirring assembly in which one end of a fixed rod passes through a hinge shaft and is fixed to the base, not rotating with the cylinder. When the double-cone mixing cylinder rotates, the stirring rod fixed inside the cylinder rotates synchronously with the cylinder. The rotating rod on the stirring rod rotates freely in the material. Through the relative movement between the stirring rod and the material, the collision, shearing, and dispersion effects between the materials are increased, effectively breaking up material agglomeration. Combined with the convection and diffusion mixing generated by the rotation of the cylinder, the mixing uniformity is significantly improved, and no additional power is required for operation.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mixing technology, specifically relating to a double cone mixer. Background Technology
[0002] The working process of the double cone mixer is as follows: several materials to be mixed are put into the double cone body through vacuum conveying or manual feeding, the cylinder cover is closed, the equipment is turned on, the double cone and the stirring blades rotate at the same time, the rotating double cone causes the materials in the cylinder to turbulently roll and mix, and the high-speed rotating stirring blades break up the clumps of materials, so that the materials are quickly mixed in the cylinder.
[0003] Existing mixers have significant shortcomings in practical applications: Firstly, the passive mixing method, relying solely on the rotation of the drum, results in weak collision and shearing effects between materials, easily leading to agglomeration or stratification. This is particularly problematic when processing viscous or fine powder materials, where the mixing uniformity fails to meet high-precision requirements. Secondly, while some improved equipment enhances mixing by adding independently driven stirring components (such as impellers or augers), this requires additional motors, transmission mechanisms, and other power systems. This not only increases equipment complexity and maintenance costs but also leads to higher overall energy consumption, contradicting the trend of green manufacturing. Therefore, a double-cone mixer is needed to address this issue. Utility Model Content

[0025] 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.
[0026] This specific embodiment is a double cone mixer, such as... Figures 1-3 As shown, the double cone mixer includes a base 1, with two bases 1 symmetrically arranged. A crossbar 2 is fixed at the bottom between the two bases 1. An installation cavity is reserved between the two bases 1, and a double cone mixing cylinder 3 is arranged in the installation cavity. Both ends of the double cone mixing cylinder 3 are provided with hinge shafts. The double cone mixing cylinder 3 is hinged to the base 1 through the hinge shafts. A transmission assembly 14 that drives the double cone mixing cylinder 3 to rotate is installed on the base 1. The transmission assembly 14 includes a worm gear 17 fixed on a hinge shaft. A transmission motor 15 is installed inside the base 1. A worm 16 is installed at the front end of the shaft of the transmission motor 15. The worm 16 and the worm gear 17 cooperate to transmit power.
[0027] The transmission assembly 14 is designed with a worm gear 17 and a worm 16. By utilizing the unidirectional transmission characteristics of the worm gear 17 and worm 16, the stability of power transmission is ensured, and a self-locking function is also provided. When the drive motor 15 stops running, the meshing of the worm 16 and the worm gear 17 can prevent the double cone mixing cylinder 3 from rotating unexpectedly due to inertia or external force, ensuring accurate positioning of the cylinder during the mixing process and improving the safety of equipment operation.
[0028] The base 1 has an agitation chamber inside, and a number of blocking rods 9 are provided at both ends of the agitation chamber. The blocking rods 9 are arranged alternately inside the agitation chamber.
[0029] Multiple blocking rods 9 are staggered in the mixing chamber to form multi-level obstacles in the material movement path. When the material moves with the cylinder rotation, it changes its direction of movement after colliding with the blocking rods 9, forming complex turbulence and diversion, further dispersing the material flow, reducing dead zone areas in the mixing chamber, and ensuring that all materials can fully contact and participate in mixing.
[0030] The base 1 is equipped with an agitation assembly 10 for agitating auxiliary materials. The agitation assembly 10 includes a fixed rod 11 rotatably disposed in the middle section of the agitation chamber. Agitation rods 12 are symmetrically fixed on the fixed rod 11. The agitation rods 12 have a U-shaped rod structure. A rotating rod 13 is rotatably disposed on the agitation rods 12. One end of the fixed rod 11 passes through a hinge shaft and is fixed on a base 1. The rotating rod 13 is rotatably sleeved on the agitation rods 12.
[0031] With the agitation component 10, one end of the fixed rod 11 passes through the hinge shaft and is fixed to the base 1, and does not rotate with the cylinder. When the double cone mixing cylinder 3 rotates, the agitation rod 12 fixed inside the cylinder rotates synchronously with the cylinder. The rotating rod 13 on the agitation rod 12 rotates freely in the material. Through the relative movement between the agitation rod 12 and the material, the collision, shearing and dispersion between the materials are increased, effectively breaking up the material agglomeration. Combined with the convection and diffusion mixing generated by the rotation of the cylinder, the mixing uniformity is significantly improved, and no additional power is required to work.
[0032] like Figure 1 and Figure 4As shown, a feed inlet is provided at the top of the base 1. An inverted U-shaped fixing frame 5 is fixed at the feed inlet of the double cone mixing cylinder 3. A screw 6 is threaded on the fixing frame 5. A top cover 4 is provided at the feed inlet. The bottom of the screw 6 is pressed against the center of the top of the top cover 4. A discharge port is provided at the bottom of the base 1. A discharge pipe 7 is installed at the discharge port. A butterfly valve is installed inside the discharge pipe 7. An installation seat is installed on one side of the discharge pipe 7. A fixing seat 8 is rotatably installed inside the installation seat. The fixing seat 8 is fixed to one end of the butterfly valve. A fixing tooth 81 protrudes from the installation seat. A handle 82 is fixed on the fixing seat 8. A positioning tooth handle 83 is hinged on the handle 82.
[0033] In actual operation, the operator can rotate the handle 82 to drive the fixed seat 8 to rotate, adjust the opening of the butterfly valve, and lock the position by the cooperation of the positioning tooth handle 83 and the fixed tooth 81, so as to achieve precise adjustment of the discharge speed and flow rate. This structure not only avoids the sealing failure problem caused by frequent opening and closing of traditional discharge valves, but also improves the controllability of the discharge process.
[0034] Working principle:
[0035] The operator adds the materials to be mixed into the double cone mixing cylinder 3 through the feed port at the top of the base 1, and then covers the feed port with the top cover 4; rotate the screw 6 on the fixing frame 5 so that its bottom presses against the center of the top of the top cover 4, and the top cover 4 and the feed port are sealed and fixed through the threaded connection between the screw 6 and the fixing frame 5.
[0036] When the drive motor 15 is started, its shaft drives the worm 16 to rotate. The worm 16 meshes with the worm wheel 17 fixed on the hinge shaft of the double cone mixing cylinder 3, transmitting power to the double cone mixing cylinder 3 and driving it to rotate around the horizontal axis. When the cylinder rotates, the internal material undergoes a combined axial and radial motion along the cylinder wall under the combined action of centrifugal force and gravity, forming convection, shearing and diffusion mixing.
[0037] One end of the fixed rod 11 passes through the hinge shaft and is fixed to the base 1, and does not rotate with the cylinder. When the double cone mixing cylinder 3 rotates, the stirring rod 12 fixed inside the cylinder rotates synchronously with the cylinder. The rotating rod 13 on the stirring rod 12 rotates freely in the material. Through the relative movement between the stirring rod 12 and the material, the collision and shearing action between the materials are increased, breaking up the material agglomeration and improving the mixing uniformity. Multiple blocking rods 9 arranged in a staggered manner in the stirring chamber form obstacles on the material movement path. After the material collides with the blocking rods 9, it changes the direction of movement, further disperses the material flow, reduces mixing dead angles, and ensures that all materials are in full contact.
[0038] After mixing, rotate the handle 82 of the butterfly valve at the discharge port 7 to rotate the fixed seat 8, adjust the opening of the butterfly valve, and lock the position through the cooperation of the positioning teeth 83 and the fixed teeth 81 to control the discharge speed and flow rate. The material is discharged through the discharge port 7.
[0039] All technical features in this embodiment can be freely combined according to actual needs.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
