Technical Field
[0001] The utility model relates to the technical field of powder material mixing, in particular to a dual-power high-speed flying knife type material mixing device. Background Art
[0002] A mixer is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials.
[0003] Among them, powder mixer is suitable for chemical, food, medicine, feed, ceramics, metallurgy and other industries, and its mixed raw materials are mainly powders.
[0004] The basic form of powder mixers on the market has been finalized, usually including an external barrel and internal stirring blades. The powdered materials are mixed evenly through the two-way stirring of the barrel and the stirring blades.
[0005] At present, the main problems faced by powder mixers are the improvement of mixing efficiency and the diversified mixing needs. The core needs are mainly reflected in: the requirements for the flexibility of adjusting the speed of the barrel and mixing blades, and the requirements for the degree of mixing adequacy.
[0006] There are currently three problems that need to be solved in existing conventional powder mixers:
[0007] The first is that the power input is only a single motor, which is distributed to the barrel and mixing blades through gear matching, and the speed adjustment flexibility is insufficient;
[0008] The second is that the shape of the barrel used for mixing and stirring is poorly matched with the stirring mechanism, the stirring degree and stirring efficiency are insufficient, dead corners are prone to occur, and it is not easy to discharge the material;
[0009] The third is that some mixing operations require the addition of liquid components, and current mixing equipment does not have this function.
[0010] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content
[0011] The utility model aims to provide a dual-power high-speed flying knife type material mixing device with sufficient power and sufficient material mixing in view of the deficiencies in the prior art.
[0012] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a dual-power high-speed flying knife type material mixing device, including a bracket, a barrel, a rotating shaft, a flying knife module and a barrel driving module;
[0013] The barrel is a closed barrel structure with an upper cylindrical portion, a lower conical portion, and a top cover being a flat top cover. The upper cylindrical region of the barrel is rotatably mounted on the bracket via a rotating shaft, so that the lower conical region of the barrel naturally droops under the influence of eccentric force;
[0014] A discharge port is arranged at the bottom end of the lower cone-shaped area, and a feed port is arranged on the top cover;
[0015] The barrel driving module is installed on the bracket and is used to drive the barrel to rotate through the rotating shaft;
[0016] The flying knife modules are distributed on the top cover, and each flying knife module comprises an independent driving motor installed on the upper end of the top cover and a flying knife blade assembly installed on the lower end of the top cover and driven by the driving motor.
[0017] Based on the above, the number of the flying knife modules is at least 1. When the number of the flying knife modules is ≥ 2, the flying knife modules are evenly distributed along the circumferential direction of the top cover.
[0018] Based on the above, the flying knife blade assembly includes a blade shaft and a blade, the main body of the blade is perpendicular to the blade shaft, and the end of the blade is bent downward to form an obtuse angle.
[0019] Based on the above, the horizontal deflection angle of two adjacent blades on the same blade shaft is 90°.
[0020] Based on the above, the blade shaft is directly connected to the output shaft of the driving motor for transmission.
[0021] Based on the above, the barrel driving module is a reduction motor, and the output shaft of the reduction motor is directly connected to the rotating shaft.
[0022] Based on the above, the side walls and the top cover of the barrel are provided with injection nozzles connected to the inside of the barrel, a liquid injection rotary joint is installed on the barrel at the position where it cooperates with the rotating shaft, and a liquid injection mechanism is installed on the bracket. The liquid injection mechanism rotates with the liquid injection rotary joint, and the liquid injection rotary joint is connected with each liquid injection nozzle through a pipeline.
[0023] Based on the above, the lower end of the flying knife blade assembly exceeds or does not exceed the height of the rotating shaft.
[0024] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model has the following advantages:
[0025] 1. Since the rotation frequencies of the barrel and the flying cutter are quite different and difficult to match, an independent drive module is set for the barrel, and an independent drive motor is set for each flying cutter module, so that both have sufficient driving power to ensure high-efficiency mixing.
[0026] 2. The barrel is designed to have a cylindrical top and a conical bottom. The conical bottom can droop naturally in a natural state, so that during the barrel flipping process, the material can be broken up and evenly distributed in the entire barrel by relying on the flipping action, the influence of material gravity and the rotating action of the flying knife. After stopping, the material can naturally fall to the bottom of the barrel and gather. It can be used to solve the mixing problems of fiber powder, clumping materials, easy-to-cake materials, and materials with added trace elements.
[0027] 3. The blade structure design and blade distribution design of the high-speed flying knife can make the blade more efficient in breaking up the material and greatly improve the mixing efficiency.
[0028] 4. Add injection nozzles, injection rotary joints and injection mechanisms to inject liquid medium into the interior while stirring to achieve different mixing requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0037] The technical solution of the utility model is further described in detail below through specific implementation methods.
[0038] Example 1
[0039] like Figure 1-Figure 5 As shown, a dual-power high-speed flying knife type material mixing device includes a bracket 1, a barrel 2, a rotating shaft 3, a flying knife module 4 and a barrel driving module 5.
[0040] The barrel 2 is a closed cylindrical structure with a cylindrical upper portion, a conical lower portion, and a top cover 6 which is a flat top cover. The upper cylindrical region of the barrel 2 is rotatably mounted on the bracket 1 via a rotating shaft 3, so that the lower conical region of the barrel 2 naturally droops under the influence of eccentric force.
[0041] A discharge port 7 is arranged at the bottom end of the lower cone-shaped area, and a feed port 8 is arranged on the top cover 6 .
[0042] The barrel driving module 5 is installed on the bracket 1 and is used to drive the barrel 2 to rotate through the rotating shaft 3. In this embodiment, the barrel driving module 5 is a reduction motor, and the output shaft of the reduction motor is directly connected to the rotating shaft 3 to provide stable and continuous power.
[0043] The flying knife modules 4 are distributed on the top cover 6 , and each flying knife module 4 includes an independent driving motor 41 installed on the upper end of the top cover 6 and a flying knife blade assembly installed on the lower end of the top cover 6 and driven by the driving motor.
[0044] In this embodiment, the flying knife blade assembly includes a blade shaft 42 and a blade 43. The main part of the blade 43 is perpendicular to the blade shaft, and the end of the blade 43 is bent downward at an obtuse angle. The horizontal deflection angle of two adjacent blades on the blade shaft 42 is 90° to increase the peeling density.
[0045] In other embodiments, the flying knife blade assembly may also conventionally include a blade shaft and ordinary blades, and there is no limitation on the number of blades and the length of the blade shaft.
[0046] In this embodiment, the lower end of the flying knife blade assembly exceeds or does not exceed the height of the rotating shaft.
[0047] The number of the flying knife modules is at least 1. When the number of the flying knife modules is ≥ 2, the flying knife modules are evenly distributed along the circumferential direction of the top cover.
[0048] In this embodiment, the number of the flying knife modules 4 is four evenly distributed. In other embodiments, the number of the flying knife modules can also be two, five or six, depending on the size of the barrel and the size of the flying knife modules.
[0049] The blade shaft 42 is directly connected to the output shaft of the driving motor 41 to achieve high-speed rotation.
[0050] Working principle description:
[0051] The fibers and fractions to be mixed are fed into the barrel 2 through the feed port 8 in the required proportion, the feed port 8 is closed, the drive motor of the flying knife module and the reduction motor of the barrel drive module are started, the barrel 2 performs a flipping motion along the rotating shaft, and the blades in the flying knife module perform a horizontal high-speed rotation motion along the blade axis. The fed materials are flipped in the barrel 2, and are cut and stirred by the rotating blades during the flipping process, so that the materials are convectively diffused in the cavity of the barrel 2, and are broken up and mixed under the action of the blades and evenly distributed in the barrel.
[0052] When the mixing is completed, the barrel 2 returns to its original position under the action of its own weight, and the evenly mixed materials inside are gathered to the discharge port 7 under the action of gravity and the conical surface, and the discharge port 7 is opened to discharge the materials.
[0053] Example 2
[0054] like Figure 6 and Figure 7 As shown, the main difference between this embodiment and embodiment 1 is that: a liquid injection nozzle 9 connected to the inside of the barrel is arranged on the side wall and the top cover 6 of the barrel 2, a liquid injection rotary joint 10 is installed on the barrel 2 at the position where it cooperates with the rotating shaft, and a liquid injection mechanism 11 is installed on the bracket 1. The liquid injection mechanism 11 is rotatably matched with the liquid injection rotary joint 10, and the liquid injection rotary joint 10 is connected with each liquid injection nozzle 9 through a pipeline 12. While the mixed material is rotated, liquid can be injected into the barrel 2 through the liquid injection rotary joint 10 and the liquid injection nozzle 9 through the liquid injection mechanism 11.
[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
