Description

Technical Field

[0001] This invention relates to the field of grain and oil processing and grinding technology, specifically an energy-saving grinding equipment for rice bran production and processing. Background Technology

[0002] Rice bran, as an important by-product of rice processing, has extremely high comprehensive utilization value in the fields of food, feed and light chemical industry. In order to meet the requirements of different application scenarios for the fineness of rice bran powder, it is usually necessary to use grinding equipment to process it further.

[0003] However, some problems still exist in actual use:

[0004] However, existing conventional rice bran grinding equipment, especially in terms of energy saving, consumption reduction, and grinding efficiency, is unable to meet the demands of modern high-yield production. In terms of energy consumption control, traditional equipment often adopts a decentralized power layout with multiple motors independently driven to achieve bidirectional grinding and material conveying. This not only leads to redundant electrical configurations and excessively long transmission links, but also generates a large amount of mechanical friction loss and wasted energy during operation, seriously deviating from the original design intention of energy saving and environmental protection. In terms of the crushing mechanism, the conventional unidirectional rotary grinding structure has a single shearing force on rice bran, and the material is very easy to escape or crush dead corners in the grinding zone, resulting in a low one-time forming qualification rate and poor fineness of the finished product. It is often necessary to repeatedly cycle grinding to achieve the fineness requirements. This inefficient crushing mode further amplifies the overall energy consumption of the equipment. In the feeding matching stage, existing equipment often adopts static single-point centralized feeding, and rice bran is very easy to accumulate and clump above the high-speed rotating grinding parts. This not only causes local overload or even machine jamming and shutdown risks, but also results in extremely uneven force in the grinding zone, which seriously restricts the development of rice bran grinding equipment towards high efficiency, continuous operation, and deep energy saving. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of existing rice bran grinding equipment, such as high energy consumption due to multi-motor drive, low efficiency of unidirectional grinding, poor fineness of finished product, and easy accumulation and agglomeration of static feed, which affects continuous production.

[0007] Technical solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving grinding equipment for rice bran production and processing, comprising;

[0009] Grinding jar, the grinding jar being provided as a container for grinding rice bran;

[0010] An energy-saving coaxial counter-rotating grinding assembly is fixedly connected to the bottom of the grinding tank, and the grinding end of the energy-saving coaxial counter-rotating grinding assembly extends into the inside of the grinding tank and cooperates with its inner wall to grind rice bran.

[0011] A uniform material spreading component is fixedly connected to the top of the energy-saving coaxial counter-rotating grinding component, and the output end of the uniform material spreading component extends directly above the grinding end of the energy-saving coaxial counter-rotating grinding component, for uniformly spraying rice bran raw materials onto the surface of the energy-saving coaxial counter-rotating grinding component.

[0012] The feeding assembly has its output end rotatably connected to the top of the uniform spreading assembly, and is fixedly installed at the bottom of the grinding tank to transport rice bran raw materials into the interior of the grinding tank.

[0013] Furthermore, the bottom of the grinding jar is fixedly connected to several support legs for stable support of the entire equipment. The bottom of the grinding jar is fixedly connected to a discharge pipe, which is interconnected with the interior of the grinding jar for discharging the ground rice bran. The bottom of the grinding jar is fixedly installed with a mounting frame, and the feeding component is fixedly connected to the mounting frame. The top of the grinding jar has a through hole for connecting the feeding component and the uniform spreading component.

[0014] Furthermore, the energy-saving coaxial anisotropic rotary grinding assembly includes;

[0015] A drive motor is fixedly connected to the bottom of the grinding jar and serves as the sole drive device for grinding.

[0016] A drive rod, which is fixedly connected to the output end of a drive motor via a coupling;

[0017] Two bevel gears, the two bevel gears being arranged symmetrically;

[0018] Two drive wheels are arranged symmetrically, and the two drive wheels mesh with two bevel gears.

[0019] The lower bevel gear shaft is fixedly connected to the outside of the drive rod, and the upper bevel gear shaft is fixedly connected to a sleeve. The drive rod passes through the inside of the sleeve and is movably connected by a bearing at the connection point, so that when the drive rod rotates, it only drives the lower bevel gear.

[0020] Furthermore, the two drive wheels, with their shafts away from the bevel gears, are movably connected to a stabilizer frame via a rotating shaft. The stabilizer frame is U-shaped, and its upper and lower ends are movably connected to the drive rod and the outer side of the sleeve via collars, respectively. This is used to allow one bevel gear to drive the other bevel gear to rotate in the opposite direction via the drive wheels. A protective cover is fitted on the outer side of the drive wheels, and the upper and lower ends of the protective cover are movably connected to the outer side of the sleeve and the drive rod via bearings, respectively, for the protection of the transmission connection parts.

[0021] Furthermore, the energy-saving coaxial counter-rotating grinding assembly also includes;

[0022] A primary grinding block, wherein the primary grinding block is in the form of a double cone;

[0023] A fine grinding block, wherein the fine grinding block is in the form of a double cone, and the fine grinding block and the primary grinding block are arranged opposite each other vertically;

[0024] The primary grinding block has grinding teeth on its edge, and the fine grinding block has grinding teeth on its edge and bottom surface. The fine grinding block and the primary grinding block are adapted to the internal space of the grinding tank for grinding rice bran multiple times. The axis of the primary grinding block is fixedly connected to the outside of the sleeve, and the axis of the fine grinding block is fixedly connected to the outside of the drive rod, so that the fine grinding block and the primary grinding block rotate in opposite directions when driven by the same drive motor.

[0025] Furthermore, the uniform material spreading component includes;

[0026] The mounting plate is fixedly connected to the top of the drive rod via a gearbox to reduce the rotational speed of the mounting plate, and the mounting plate is located directly below the through hole;

[0027] Four feeding pipes, each with a feeding head installed at its bottom, are arranged in a circular array to evenly deliver rice bran to the top of the primary grinding block.

[0028] The mounting plate has a distribution groove on its surface, and the top ends of the four material dispensing pipes are fixedly connected to the bottom of the mounting plate and pass through the mounting plate and communicate with the distribution groove.

[0029] Furthermore, grooves are provided on both sides of the distribution groove, and the cross-section of the grooves is T-shaped, for connecting the conveying end of the feeding assembly.

[0030] Furthermore, the feeding assembly includes;

[0031] A conveyor, which is fixedly connected to the surface of the mounting frame, is used to transport rice bran into the interior of the grinding tank;

[0032] A feed hopper, which is fixedly installed at the feed inlet of the conveyor;

[0033] Two conveying pipes, one end of which is fixedly connected to the output end of the conveyor via a tee;

[0034] The other end of each of the two conveying pipes is fixedly connected to a sealing cap, and the outer side of the conveying pipe is fixedly connected to the outer side of the grinding tank through a connector for conveying rice bran.

[0035] Furthermore, the sealing cover is annular, and sliding strips are fixedly connected to both the inner and outer sides of the sealing cover. The sealing cover is located at the top of the distribution groove, and the sliding strips are slidably connected to the inside of the groove. This is to prevent the conveying pipe from obstructing the installation plate from rotating and spreading the four spreading pipes evenly when conveying rice bran.

[0036] Compared with existing technologies, this energy-saving grinding equipment for rice bran production and processing has the following advantages:

[0037] I. This invention, through its energy-saving coaxial counter-rotating grinding component, breaks away from the complex mode of traditional equipment where multiple motors drive each component separately. It innovatively uses only one drive motor as the sole core power source. Through precise bevel gear and transmission wheel transmission, the single motor not only efficiently achieves high-speed coaxial counter-rotation of the primary grinding block and the fine grinding block, but also synchronously links the top gearbox to drive the uniform material spreading component to operate at low speed. This multi-functional power distribution mechanism fundamentally simplifies the transmission chain, reduces energy loss, and significantly reduces the overall operating power of the equipment while ensuring powerful grinding power, achieving a significant and long-lasting energy-saving effect.

[0038] II. This invention enhances the pulverization and refinement of rice bran through a two-stage anisotropic grinding structure constructed by the cooperation of a primary grinding block and a fine grinding block. Utilizing the unique double-cone shape and the high-speed, coaxial, opposite-rotation characteristics of both, the rice bran entering the grinding zone is subjected to significantly increased relative shear and compressive forces. The rice bran is first coarsely crushed by the intense tearing of the grinding teeth at the edge of the primary grinding block, and then flows downwards along the double-cone guide surface into the fine grinding zone, where it is thoroughly refined by the secondary deep grinding of the dense grinding teeth at the edge and bottom of the fine grinding block. This effectively overcomes the problems of material escape or uneven pulverization caused by traditional unidirectional grinding, resulting in a high one-time finished product qualification rate and significantly improving the fineness and processing quality of the finished rice bran.

[0039] Third, this invention perfectly solves the interference problem between static continuous feeding and dynamic rotating feeding by using a dynamic sliding seal between the uniform feeding component and the conveying component. During the feeding process, the rotating mounting plate uses centrifugal force to evenly distribute the rice bran falling into the distribution trough to the four feeding pipes, achieving ring-shaped spraying without dead angles. This eliminates the phenomenon of material accumulating and clumping at a single point or local overload, ensuring uniform force in the grinding zone. At the same time, the annular sealing cover at the bottom of the conveying pipe adaptively slides within the T-shaped groove through inner and outer sliding strips. This ensures a continuous supply of material to the rotating plate while forming a reliable dynamic seal, never interfering with the free operation of the mounting plate. This achieves efficient and continuous production operation with the equipment grinding as it feeds in.

[0040] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] like Figure 1-9 As shown, the present invention provides a technical solution: an energy-saving grinding equipment for rice bran production and processing, comprising: a grinding tank 1, wherein the grinding tank 1 provides a rice bran grinding container;

[0053] Energy-saving coaxial counter-rotating grinding component 2 is fixedly connected to the bottom of grinding tank 1, and the grinding end of the energy-saving coaxial counter-rotating grinding component 2 extends into the interior of grinding tank 1 and cooperates with its inner wall to grind rice bran.

[0054] The uniform material spreading component 3 is fixedly connected to the top of the energy-saving coaxial counter-rotating grinding component 2, and the output end of the uniform material spreading component 3 extends directly above the grinding end of the energy-saving coaxial counter-rotating grinding component 2, and is used to uniformly spray rice bran raw materials onto the surface of the energy-saving coaxial counter-rotating grinding component 2.

[0055] The feeding component 4 is rotatably connected to the top of the uniform spreading component 3, and is fixedly installed at the bottom of the grinding tank 1 to transport rice bran raw materials into the interior of the grinding tank 1.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, several support legs 5 are fixedly connected to the bottom of the grinding tank 1, providing a solid foundation for the overall stability of the equipment. This ensures that the equipment will not vibrate or shift when the internal grinding components rotate at high speed in opposite directions, greatly improving operational safety. A mounting frame 7 is fixedly installed at the bottom of the grinding tank 1, and the feeding component 4 is fixedly connected to the mounting frame 7. This stable external mounting structure effectively ensures the structural stability of the feeding component 4 during continuous conveying of rice bran, preventing loosening of the conveying mechanism due to long-term operation. A through hole 8 is provided at the top of the grinding tank 1 for... The connection between the feeding component 4 and the uniform spreading component 3 provides a reliable channel for the material to smoothly cross from the external conveying pipe 403 to the internal rotating spreading component. The bottom of the grinding tank 1 is fixedly connected to the discharge pipe 6, and the discharge pipe 6 is interconnected with the inside of the grinding tank 1. The qualified rice bran powder after the upper double-stage grinding falls smoothly to the bottom of the grinding tank 1 under its own gravity, and is finally continuously discharged through the discharge pipe 6. This realizes the fully automatic production line flow of rice bran from feeding, grinding to discharging, which significantly improves the production continuity and processing efficiency of the whole set of equipment.

[0057] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the energy-saving coaxial counter-rotating grinding assembly 2 includes a drive motor 201 fixedly connected to the bottom of the grinding jar 1. This motor, as the sole driving device for grinding, drives the drive rod 202 to rotate in the forward direction, effectively reducing the number of power devices and significantly lowering the energy consumption of the equipment. The drive rod 202 is fixedly connected to the output end of the drive motor 201 via a coupling. When rotating, it drives the lower bevel gears 203, which are symmetrically arranged on the outer side, to rotate. Because the drive rod 202 passes through the sleeve 205 and the connection is made via a bearing, it ensures that when the drive rod 202 rotates, it only drives the lower bevel gears 203 and does not interfere with the movement of the sleeve 205. At this time, the two symmetrically arranged transmission wheels 204 and the two bevel gears 203... 03. The two transmission wheels 204 are meshed with each other. The shafts of the two transmission wheels 204 away from the bevel gear 203 are movably connected to the U-shaped stabilizer 206 through a rotating shaft. The upper and lower ends of the stabilizer 206 are respectively movably connected to the outer side of the drive rod 202 and the sleeve 205 through collars. Under this limiting cooperation, one bevel gear 203 drives the other bevel gear 203, which is fixedly connected to the sleeve 205 at the shaft center, to rotate in the opposite direction through the transmission wheel 204. The outer side of the transmission wheel 204 is covered with a protective cover 207. The upper and lower ends of the protective cover 207 are respectively movably connected to the outer side of the sleeve and the drive rod 202 through bearings. The transmission connection parts are isolated and protected simultaneously, ensuring the safety and service life of the complex transmission structure.

[0058] The energy-saving coaxial counter-rotating grinding assembly 2 also includes a primary grinding block 208 and a fine grinding block 209 in the form of a double cone. The fine grinding block 209 and the primary grinding block 208 are arranged opposite each other and adapted to the internal space of the grinding tank 1. As the sleeve 205 and the drive rod 202 rotate in opposite directions, the primary grinding block 208, which is fixedly connected to the outside of the sleeve 205 at the center, and the fine grinding block 209, which is fixedly connected to the outside of the drive rod 202 at the center, achieve coaxial counter-rotation at high speed inside the grinding tank 1, so that the fine grinding block 209 and the primary grinding block 208 rotate in opposite directions when driven by the same drive motor 201.

[0059] The primary grinding block 208 has grinding teeth on its edge, and the fine grinding block 209 also has grinding teeth on its edge and bottom surface. This is used to grind the rice bran multiple times. The rice bran is first crushed under the strong shearing and compression of the grinding teeth on the edge of the primary grinding block 208, which is a double cone. Then, it enters the area of ​​the fine grinding block 209 along the double cone structure and is then ground a second time in a deep and fine manner using the grinding teeth on its edge and bottom surface. This synergistic effect of dual anisotropic grinding effectively overcomes the limitations of traditional unidirectional grinding and significantly improves the efficiency of rice bran grinding and the fineness of the finished product.

[0060] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, the uniform spreading component 3 includes a mounting plate 301. The mounting plate 301 is fixedly connected to the top of the drive rod 202 via a gearbox and is located directly below the through hole 8. This gearbox connection design effectively reduces the rotational speed of the mounting plate 301, preventing rice bran from splashing outwards due to excessive centrifugal force. A distribution groove 304 is provided on the surface of the mounting plate 301. T-shaped sliding grooves 305 are provided on both sides of the distribution groove 304 for connecting the conveying end of the feeding component 4. The rice bran falling into the distribution groove 304 can be uniformly guided under the stable centrifugal force of low-speed rotation, providing a reliable basic structural guarantee for subsequent uniform spreading.

[0061] Four feeding pipes 302 are evenly distributed in a ring array. Their top ends are fixedly connected to the bottom of the mounting plate 301 and pass through the mounting plate 301 and are interconnected with the distribution groove 304. Each of the four feeding pipes 302 has a feeding head 303 installed at its bottom. After the rice bran is evenly distributed into the four feeding pipes 302, it is finally evenly transported to the top of the primary grinding block 208 through the feeding head 303. This ring array spraying method effectively avoids the local accumulation and clumping of materials in a static state, ensuring that the rice bran can enter the two-stage anisotropic grinding area in all directions evenly, which greatly improves the smoothness of continuous feeding operation and the uniformity of overall grinding processing.

[0062] like Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 As shown, the feeding assembly 4 includes a conveyor 401 fixedly connected to the surface of the mounting frame 7, and a feeding hopper 402 is fixedly installed at the feed inlet of the conveyor 401. After the operator puts the rice bran raw material into the feeding hopper 402, the conveyor 401 provides stable lifting and conveying power, realizing the automated and continuous feeding operation of rice bran into the grinding tank 1, effectively reducing the labor intensity of manual feeding and improving the feeding efficiency.

[0063] One end of each of the two conveying pipes 403 is fixedly connected to the output end of the conveyor 401 via a tee. The other end of each of the two conveying pipes 403 is fixedly connected to a sealing cap 404. The outer side of each conveying pipe 403 is fixedly connected to the outer side of the grinding tank 1 via a connector for conveying rice bran. The rice bran is smoothly diverted from the output end of the conveyor 401 to the two conveying pipes 403 via a tee. This parallel diversion design of the two pipes effectively balances the material flow pressure when conveying with a single pipe, avoids congestion inside the pipe, and ensures that the rice bran is continuously and stably conveyed to the top of the grinding tank 1.

[0064] The sealing cover 404 is annular and located at the top of the distribution groove 304. Sliding strips 405 are fixedly connected to both the inner and outer sides of the sealing cover 404, and the sliding strips 405 are slidably connected to the inside of the sliding grooves 305 on both sides of the distribution groove 304. When the conveying pipe 403 continuously conveys rice bran downwards, the annular sealing cover 404 dynamically slides adaptively in the sliding grooves 305 through the sliding strips 405, which resolves the motion interference between the statically fixed conveying pipe 403 and the high-speed rotating mounting plate 301. This not only achieves effective flow guidance and leakage prevention in the material conveying process, but also completely avoids the conveying pipe 403 from hindering the mounting plate 301 from driving the four spreading pipes 302 to rotate and spread material evenly, ensuring the efficient and coordinated operation of the entire static feeding and dynamic spreading system.

[0065] Working principle: Before the equipment feeds rice bran, the system pre-starts the only driving power source, namely the drive motor 201. After the drive motor 201 starts, it drives the drive rod 202 to rotate in the forward direction. The bevel gear 203 at the bottom of the drive rod 202 rotates accordingly. Through the cooperation of the transmission wheel 204 and the stabilizer 206, it drives the upper bevel gear 203 and the sleeve 205 to rotate in the opposite direction. At the same time, the gearbox at the top of the drive rod 202 drives the mounting plate 301 to start rotating at a low speed. The four feeding pipes 302 and the feeding head 303 rotate synchronously. At this time, the primary grinding block 208 and the fine grinding block 209 inside the grinding tank 1 are in a standby working state of high-speed opposite rotation, ready for continuous feeding.

[0066] After the grinding components are pre-started, the feeding operation begins. The operator puts the rice bran raw material into the feed hopper 402 of the feeding component 4. The rice bran is then conveyed to the top of the grinding tank 1 by the conveyor 401 through two conveying pipes 403. At this time, since the mounting plate 301 is already rotating, the sealing cover 404 fixed at the bottom of the conveying pipe 403 achieves dynamic sliding sealing in the T-shaped sliding groove 305 of the mounting plate 301 through the sliding strips 405 on its inner and outer sides. This structural design allows the rice bran to continuously fall into the rotating distribution groove 304 without hindering the rotation of the mounting plate 301. After entering the distribution groove 304, the rice bran is evenly distributed into the four sprinkling pipes 302 under the action of the centrifugal force of rotation. Finally, it is evenly sprayed in a ring shape by the sprinkling head 303 directly above the high-speed rotating primary grinding block 208, effectively preventing the material from accumulating and clumping in a static state.

[0067] In the two-stage counter-rotating grinding and discharge stage, the evenly sprinkled rice bran is instantly rolled into the high-speed counter-rotating grinding area. As the sleeve 205 and the drive rod 202 drive the primary grinding block 208 and the fine grinding block 209 to rotate in opposite directions, the rice bran first completes primary crushing under the shearing and squeezing of the grinding teeth on the edge of the double-cone primary grinding block 208.

[0068] Subsequently, the rice bran after primary crushing flows downward along the double-cone structure and enters the fine grinding block 209 area. It undergoes a second deep fine grinding using the grinding teeth on the edge and bottom surface of the fine grinding block 209. The qualified rice bran powder after double counter-rotating grinding falls to the bottom of the grinding tank 1 under the action of gravity and is finally continuously discharged through the discharge pipe 6. Throughout the process, the equipment uses a single motor to achieve the linkage of coaxial counter-rotation and uniform material spreading, realizing grinding as it feeds in, which greatly improves the efficiency and fineness of rice bran grinding and effectively reduces the energy consumption of the equipment.
