Description

A high-speed powder mixer Technical Field

[0001] This utility model relates to the field of mixer technology, specifically a high-speed powder mixer. Background Technology

[0002] A powder mixer is a key piece of equipment that achieves uniform mixing of powders through efficient mechanical action. It is used in pharmaceuticals, food, chemicals, powder metallurgy and other fields. The high-speed rotating blades cut agglomerated powders into micron-sized particles, significantly increasing the contact area. The blades cause the material to circulate under the action of centrifugal force and gravity, avoiding dead corner accumulation.

[0003] Existing powder mixers integrate the mixing tank, scraper motor, and high-speed motor onto a tilting shaft. The tilting shaft is fixed to the frame in a cantilever manner. The tilting shaft needs to withstand a large bending moment, and the bearings mated with the shaft also bear a large load, which can easily lead to wear and fatigue. In addition, the tank and motor parts require wiring, and the cables and pipelines share the same outlet, which can have a certain impact on the transmission and stability between them. Summary of the Invention

[0004] The purpose of this invention is to provide a high-speed powder mixer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-speed powder mixer includes a frame, a support plate on the outside of the frame, a support member on the top of the support plate, a rotating shaft rotatably connected between two support members, a mixing tank mounted on the rotating shaft, a high-speed motor and a wall-scraping motor mounted outside the mixing tank, the high-speed motor connected to a shearing blade, and the wall-scraping motor connected to a wall-scraping blade, both ends of the rotating shaft having cavities, a cable installed inside one cavity of the rotating shaft, and a connecting pipe installed inside the other cavity of the rotating shaft, the connecting pipe being connected to a water pipe and an oil pipe on the tank, a fixing plate on the frame, a rotating motor mounted on the fixing plate, and a transmission mechanism between the rotating motor and the rotating shaft, the rotating motor driving the rotating shaft and the mixing tank to rotate through cooperation with the transmission mechanism.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: the transmission mechanism includes a pulley and a transmission belt, the pulley is provided at the end of the flipping shaft near the flipping motor, and a transmission belt is provided between the drive end of the flipping motor and the pulley.

[0009] In one alternative: the outer wall of the mixing tank is provided with a side plate, the scraper motor is mounted on the side plate, and the scraper motor is used to drive the scraper blade to rotate.

[0010] In one alternative: the bottom of the mixing tank is provided with a base plate, and the high-speed motor is mounted on the base plate.

[0011] In one alternative: the top of the mixing tank is provided with a feed pipe for feeding materials.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The high-speed powder mixer supports the two ends of the tilting shaft through the frame. The support structure at both ends greatly increases the structural strength of the tilting shaft, which greatly improves its stress condition, increases the load-bearing capacity of the tilting shaft, improves the wear and fatigue condition of the bearings, and extends the service life of the bearings. The support structure at both ends ensures the stability of the overall equipment when it is running at high speed, thereby reducing its vibration to a certain extent.

[0014] 2. Both ends of the flip shaft are equipped with cavities, allowing cables, water pipes, and oil pipes to be arranged separately. This eliminates unnecessary isolation measures and removes the mutual influence between them, ensuring the stability and safety of transmission. The support structure at both ends has higher strength and smoother operation, making it convenient to increase the size and capacity of the product, and suitable for large-scale industrial production.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0019] In one embodiment, as shown in Figure 1, a high-speed powder mixer includes a frame 1. A support plate 11 is provided on the outside of the frame 1. A support member 12 is provided on the top of each of the two support plates 11. A rotating shaft 5 is rotatably provided between the two support members 12. That is, the rotating shaft 5 is mounted on the frame 1 through the support structures at both ends. A mixing tank 2 is provided on the rotating shaft 5. A high-speed motor 4 and a wall scraping motor 3 are provided on the outside of the mixing tank 2. The high-speed motor 4 is connected to a shearing blade, and the wall scraping motor 3 is connected to a wall scraping blade.

[0020] To avoid external cables from getting tangled and to facilitate cable routing, the tilting shaft 5 is designed as a hollow structure. The cable 6 is led out from the left side of the tilting shaft 5, and the water pipe and oil pipe connected to the tank are led out from the other side of the tilting shaft 5. A fixing plate 9 is provided on the frame 1, and a tilting motor 7 is provided on the fixing plate 9. A transmission mechanism is provided between the tilting motor 7 and the tilting shaft 5. The tilting motor 7 drives the tilting shaft 5 and the mixing tank 2 to rotate through cooperation with the transmission mechanism.

[0021] The high-speed powder mixer supports both ends of the tilting shaft 5 via the frame 1. The structure of supporting both ends greatly increases the structural strength of the tilting shaft 5 and increases its load-bearing capacity. The cables of the tank and each motor are led out through the cavity at the left end of the tilting shaft 5, and the water pipes and oil pipes of the tank are led out from the cavity at the right end of the tilting shaft 5 and connected to the corresponding electrical control box or other pneumatic and hydraulic devices. As an example, the left, right and up and down positions of the various components shown in the attached figure are only one arrangement method, and the specific positions are set according to specific needs.

[0022] In one embodiment, as shown in FIG1, the transmission mechanism includes a pulley 13 and a transmission belt 10. The pulley 13 is provided at one end of the flip shaft 5 near the flip motor 7. The transmission belt 10 is provided between the drive end of the flip motor 7 and the pulley 13. The high-speed motor 4 drives the shearing blade, the wall scraping motor 3 drives the wall scraping blade, and the flip motor 7 drives the transmission mechanism to drive the flip shaft 5 to rotate according to the set logic program.

[0023] In one embodiment, as shown in FIG1, the outer side wall of the mixing tank 2 is provided with a side plate 14, and the scraper motor 3 is mounted on the side plate 14. The scraper motor 3 is used to drive the scraper blade to rotate.

[0024] In one embodiment, as shown in FIG1, a bottom plate 15 is provided at the bottom of the mixing tank 2, and the high-speed motor 4 is mounted on the bottom plate 15.

[0025] In one embodiment, as shown in FIG1, a feed pipe 16 for feeding is provided on the top of the mixing tank 2.

[0026] The existing powder mixer integrates the mixing tank 2, scraper motor 3, and high-speed motor 4 onto the tilting shaft 5, as shown in Figure 2. The tilting shaft 5 is fixed to the frame 1 in a cantilever manner and supported by the frame 1. The tilting shaft 5 is subjected to uneven stress and needs to withstand a large bending moment. The bearings mated with the shaft also bear a large load, which easily leads to wear and fatigue. The tilting shaft 5 has a cavity inside, which weakens its strength to a certain extent and is even more detrimental to the cantilever structure. The equipment is prone to vibration when running at high speed, which affects its service life and stability. Because the tank and motor parts require wiring, the cables and pipelines share a common outlet, which will have a certain impact on the transmission and stability between them. Appropriate isolation measures need to be adopted. When the equipment is small or has low power, the above-mentioned effects are less significant. However, when the model is increased and the capacity is expanded, the above-mentioned effects are more obvious, making it unsuitable for large-scale industrial production.

[0027] The above embodiments of this utility model provide a high-speed powder mixer. The end support structure significantly increases the structural strength of the tilting shaft 5, greatly improving its stress condition and increasing its load-bearing capacity. Because the bearings are arranged at both ends of the shaft, they share the load, improving wear and fatigue conditions and extending bearing life. The end support structure provides reliable stability for the entire equipment during high-speed operation, thereby reducing vibration to a certain extent. Cavities are provided at both ends of the tilting shaft 5, allowing cables, water pipes, and oil pipes to be arranged separately, eliminating unnecessary isolation measures and preventing mutual interference, thus ensuring transmission stability and safety. The end support structure has higher strength and smoother operation, facilitating larger product models and expanded capacity, making it suitable for large-scale industrial production.

[0028] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
