Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a compound wheat bran extractor. Background Technology

[0002] Wheat bran is the seed coat (i.e., wheat husk) that is sieved out after wheat is milled into flour. It is in the form of flakes or powder. In the processing of wheat bran flour, wheat bran can be fed into a flour extractor for crushing. Existing flour extractors usually use the combination of two grinding surfaces, inner and outer, to grind the raw materials. Due to the limited effective grinding area, the grinding efficiency of the raw materials is low.

[0003] Therefore, in order to improve the grinding and powder extraction efficiency of materials such as wheat bran, wheat, and corn, there is an urgent need for a powder extraction machine that can crush and grind these materials, improve the crushing and grinding efficiency, and be applicable to various fields such as chemical, feed, and grain processing, so as to improve the current material crushing and grinding efficiency. Utility Model Content

[0004] The purpose of this invention is to replace the use of a grinding mill, reduce operating costs, and increase the flour yield, and thus a compound wheat bran extractor is invented.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A compound wheat bran extractor includes a support plate. Two sets of sealing plates are fixed to the top outer wall of the support plate. Baffles are fixed to the opposite outer walls of the sealing plates. A top plate is fixed to the top outer walls of the baffles and sealing plates. A first mounting box and a second mounting box are fixed to one side outer wall of the sealing plates. A first motor and a second motor are fixed to one side outer wall of the first mounting box and the second mounting box. A first sealing cylinder and a second sealing cylinder are fixed to the opposite outer wall of the sealing plates. Rollers are rotatably connected to the inner walls of both ends of the first sealing cylinder and the second sealing cylinder. The output ends of the second motor and the first motor are respectively connected to the rollers via couplings. Multiple spirally distributed grinding discs are fixed to the outer wall of the rollers. Gear rings are opened on the outer wall of the grinding discs, and there is a gap between each adjacent spirally distributed grinding disc.

[0006] As a further embodiment of this utility model: a feed inlet is inserted into the top outer wall of the second sealing cylinder, a guide pipe is inserted between the first sealing cylinder and the second sealing cylinder, and a discharge port is inserted into the bottom outer wall of the first sealing cylinder.

[0007] As a further embodiment of this utility model: a second sealing bearing seat and a first sealing bearing seat are fixed to the inner wall of the sealing plate, and one end of the roller shaft is rotatably connected to the inner wall of the second sealing bearing seat and the first sealing bearing seat respectively.

[0008] As a further improvement of this utility model: the outer wall of the spirally distributed grinding disc has a rectangular through groove, and the outer wall of the spirally distributed grinding disc is provided with multiple grinding teeth.

[0009] As a further embodiment of this utility model: multiple sets of side-by-side grinding discs are fixed to the outer walls on both sides of the roller shaft, and the side-by-side grinding discs have the same structure as the spirally distributed grinding discs.

[0010] As a further improvement of this utility model, support legs are fixed at the four corners of the bottom outer wall of the support plate.

[0011] As a further improvement of this utility model, a hook is fixed to the top outer wall of the sealing plate.

[0012] As a further improvement of this utility model: an independent motor is fixed to the bottom outer wall of the support plate, and the output shaft of the independent motor is connected to a set of roller shafts through a V-belt.

[0013] The beneficial effects of this utility model are as follows: 1. By setting rectangular through grooves and grinding teeth on the outer wall of the spiral distributed grinding discs, the grinding teeth can crush the material passing through during rotation. The crushed material enters the gap between two adjacent spiral distributed grinding discs through the rectangular through grooves on the outer wall of the spiral distributed grinding discs. Then, the crushed material inside the gap is crushed by the spiral distributed grinding discs rotating at different times, thereby crushing the crushed material and improving the crushing and grinding efficiency of the material by multiple spiral distributed grinding discs in rotation. While improving the material grinding and processing efficiency, this powder extractor can replace the crushers, grinding mills and pellet mills on the market, thus improving the applicability of the powder extractor.

[0014] 2. By setting multiple sets of parallel grinding discs on both sides of the roller shaft, the rotating spiral grinding discs can simultaneously crush and grind the materials inside the first and second sealed cylinders, thereby further improving the crushing and grinding efficiency of the powder extractor.

Detailed Implementation

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0019] Example 1: A compound wheat bran extractor, such as Figure 1-10As shown, the system includes a support plate 1. Two sets of sealing plates 8 are fixed to the top outer wall of the support plate 1. Baffles 10 are fixed to the opposite outer walls of the sealing plates 8. A top plate 14 is fixed to the top outer walls of the baffles 10 and the sealing plates 8. A first mounting box 3 and a second mounting box 6 are fixed to one side outer wall of the sealing plates 8. A first motor 4 and a second motor 5 are fixed to one side outer wall of the first mounting box 3 and the second mounting box 6. A first sealing cylinder 21 and a second sealing cylinder 22 are fixed to the opposite outer wall of the sealing plates 8. Rollers 15 are rotatably connected to the inner walls of the first sealing cylinder 21 and the second sealing cylinder 22. The output ends of the second motor 5 and the first motor 4 are connected to the rollers 15 via couplings. Multiple spirally distributed grinding discs 17 are fixed to the outer wall of the rollers 15. Gear rings 16 are opened on the outer wall of the grinding discs 17. There is a gap between two adjacent spirally distributed grinding discs 17. The second sealing cylinder 22 has a feed inlet 9 inserted into the top outer wall, a guide tube 19 is inserted between the first sealing cylinder 21 and the second sealing cylinder 22, and a discharge port 13 is inserted into the bottom outer wall of the first sealing cylinder 21. The inner wall of the sealing plate 8 is fixed with a second sealing bearing seat 11 and a first sealing bearing seat 12, and one end of the roller shaft 15 is rotatably connected to the inner wall of the second sealing bearing seat 11 and the first sealing bearing seat 12 respectively. The outer wall of the spirally distributed grinding disc 17 has a rectangular through groove 20, and the outer wall of the spirally distributed grinding disc 17 is provided with multiple grinding teeth 23.

[0020] First, the material to be crushed and ground is fed into the second sealed cylinder 22 through the feed inlet 9. Then, the first motor 4 and the second motor 5 are started simultaneously, driving the upper and lower rollers 15 to rotate relative to each other. At this time, the material inside the second sealed cylinder 22 is conveyed forward by the rotation of multiple spirally distributed grinding discs 17. While the material is being conveyed forward, it is crushed by the extrusion of multiple rotating spirally distributed grinding discs 17 and toothed rings 16. When the material is pushed forward by the spirally distributed grinding discs 17, it is crushed by multiple spirally distributed grinding discs 17. When the crushed material moves to the other end of the second sealed cylinder 22, it will fall into the first sealed cylinder 21 through the guide pipe 19. Then, the rotating rollers 15 inside the first sealed cylinder 21 will convey the material to the side of the feed inlet 13 while continuing to grind the material by the rotating spirally distributed grinding discs 17 and toothed rings 16. The ground material will then be discharged out of the equipment through the discharge inlet 13, thus completing the crushing and grinding of materials such as wheat and corn. By setting rectangular through grooves 20 and grinding teeth 23 on the outer wall of the spiral distributed grinding disc 17, the grinding teeth 23 can crush the material passing through when rotating. The crushed material enters the gap between two adjacent spiral distributed grinding discs 17 through the rectangular through grooves 20 on the outer wall of the spiral distributed grinding disc 17. Then, the crushed material inside the gap is crushed by the spiral distributed grinding discs 17 rotating at different times, thereby crushing the crushed material and improving the crushing and grinding efficiency of the material by the multiple spiral distributed grinding discs 17 rotating in the process. While improving the material grinding and processing efficiency, this powder extractor can replace the effect of crushers and pellet mills on the market, thus improving the applicability of the powder extractor.

[0021] like Figure 3-4 As shown, multiple sets of parallel grinding discs 18 are fixed to the outer walls of both sides of the roller shaft 15. The parallel grinding discs 18 have the same structure as the spiral grinding discs 17. By setting multiple sets of parallel grinding discs 18 on both sides of the roller shaft 15, the materials inside the first sealing cylinder 21 and the second sealing cylinder 22 can be crushed and ground simultaneously in conjunction with the rotating spiral grinding discs 17, thereby further improving the crushing and grinding efficiency of the powder extractor.

[0022] like Figure 1-2 As shown, support legs 2 are fixed at the four corners of the bottom outer wall of the support plate 1.

[0023] The sealing plate 8 has a hook 7 fixed to its top outer wall; after the traction rope is fixed to the inner wall of the hook 7, the powder collector can be lifted as a whole by the traction rope, which facilitates the transportation of the powder collector.

[0024] In this embodiment, the toothed ring 16, the spirally distributed grinding disc 17, and the side-by-side distributed grinding disc 18 are made of metal or alloy.

[0025] In this embodiment, the hourly output of the compound wheat bran extractor can reach between 1.2 and 1.5 tons, and the speed of the first motor 4 and the second motor 5 is 1440 r / min, with a power between 4 and 5.5 kW. Working principle: The material to be crushed and ground is fed into the second sealed cylinder 22 through the feed inlet 9. Then, the first motor 4 and the second motor 5 are started simultaneously, driving the upper and lower rollers 15 to rotate relative to each other. At this time, the material inside the second sealed cylinder 22 is conveyed forward by the rotation of multiple spirally distributed grinding discs 17. While being conveyed forward, the material is crushed by the extrusion of multiple rotating spirally distributed grinding discs 17 and toothed rings 16. When the crushed material moves to the other end of the second sealed cylinder 22, it will fall into the first sealed cylinder 21 through the guide pipe 19. Then, the rotating rollers 15 inside the first sealed cylinder 21 will convey the material to the side of the feed inlet 13 while continuing to grind the material by the rotating spirally distributed grinding discs 17 and toothed rings 16. The ground material will then be discharged outside the equipment through the feed inlet 13.

[0026] Example 2: Dual-type wheat bran extractor, such as Figure 6 As shown, this embodiment makes the following improvements based on embodiment 1: An independent motor 24 is fixed to the bottom outer wall of the support plate 1, and the output shaft of the independent motor 24 is connected to a set of roller shafts 15 through a V-belt 25; a single motor can be used to drive the two roller shafts 15 inside the powder extractor to rotate synchronously through the V-belt 25, allowing users to choose between single-motor and dual-motor transmission methods for the powder extractor as needed, thus improving the applicability of the powder extractor. At the same time, corresponding protective covers can be set on the outer walls of the roller shafts 15 and the independent motor 24 to improve the service life of the roller shafts 15, the independent motor 24, and the V-belt 25.

[0027] In this embodiment, the power of the independent motor 24 is between 7.5-11kw, and the speed is 1440r / min.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
