DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail through the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the scope of the utility model.

[0028] It should be noted that when an element is referred to as being "disposed on, provided with" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected, connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Fixed connection" means a fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this article. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only and do not represent the only implementation method.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art of the present invention. The terms used in the specification are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] Example 1, please refer to the attached manual Figure 1-5The utility model provides a technical solution: a ring-shaped feeding distribution distributor, including a feed barrel 1. In order to solve the problem that the distribution distributor in the prior art still has uneven distribution, a buffer barrel 2 is arranged inside the feed barrel 1, and a branch pipe 3 is arranged on the outer periphery of the feed barrel 1. When working, the material is first put into the buffer barrel 2 from the top of the buffer barrel 2. As the material continues to enter the buffer barrel 2 and accumulates, the material will overflow evenly from the top of the buffer barrel 2 around the circle, and the overflowed material will then enter the feed barrel 1 and be discharged through the branch pipe 3 on the feed barrel 1. The overflow distribution method is adopted to fully reduce the uneven distribution phenomenon caused by the impact force of the material.

[0031] Furthermore, a secondary feed distributor 4 is provided at the bottom of the branch pipe 3, and the secondary feed distributor 4 is used to realize the secondary distribution of materials. The secondary feed distributor 4 includes an upper plate 6, a lower plate 7 and a baffle plate 8. The upper plate 6 is in a circular ring structure and is fixedly arranged at the outer circle of the bottom of the branch pipe 3. The lower plate 7 is in a circular plate structure and is arranged below the upper plate 6. A discharge gap is formed between the upper plate 6 and the lower plate 7. A plurality of baffle plates 8 are provided, and the plurality of baffle plates 8 are connected between the upper plate 6 and the lower plate 7 in a circular array. When working, the material in the branch pipe 3 enters between the upper plate 6 and the lower plate 7, and the material is evenly discharged from the gap between the plurality of baffle plates 8, thereby realizing the purpose of secondary distribution. After two uniform distributions, the material at a high place, especially the material fed in one place, can be evenly distributed to a wider receiving surface at a low place.

[0032] In the utility model, the feeding barrel 1 is located in the material processing barrel 11 for use, and is particularly suitable for uniform material distribution.

[0033] It should be noted that a discharge hole 5 is provided at one end of the branch pipe 3 away from the secondary feed distributor 4, and the discharge hole 5 is connected to the interior of the feed barrel 1. The material overflowing from the upper end of the buffer barrel 2 enters the branch pipe 3 through the discharge hole 5. The branch pipe 3 is an L-shaped bend structure, and the bending part of the L-shaped bend structure is arc-shaped, which is conducive to the passage of materials.

[0034] In actual use, the buffer barrel 2 needs to meet the following conditions to achieve the purpose of reducing material impact and evenly distributing the material: the diameter of the buffer barrel 2 needs to be smaller than the diameter of the feed barrel 1, a first gap 9 is formed between the outer ring of the buffer barrel 2 and the inner wall of the feed barrel 1, the bottom of the buffer barrel 2 is fixedly connected to the bottom of the feed barrel 1, a second gap 10 is formed between the top of the buffer barrel 2 and the top of the feed barrel 1, and the discharge hole 5 is located on the outer periphery of the buffer barrel 2; when working, the material overflowing from the upper end of the buffer barrel 2 will first be discharged from the second gap 10 into the first gap 9 between the feed barrel 1 and the buffer barrel 2, and then enter the branch pipe 3; the specific dimensions of the feed barrel 1, the buffer barrel 2, the first gap 9 and the second gap 10 can be adjusted according to actual needs, which will not be repeated here.

[0035] It should also be noted that at least two branch pipes 3 are provided to achieve the purpose of uniform distribution of materials. There are two, four, six, eight, and twelve branch pipes, which are usually arranged in an even number.

[0036] It is worth noting that the upper ends of the feed barrel 1 and the buffer barrel 2 are open to allow materials to enter, and the bottoms of the feed barrel 1 and the buffer barrel 2 are closed to allow materials to enter the branch pipe 3 without leaking from the bottom of the feed barrel 1 and the buffer barrel 2.

[0037] Example 2, please refer to the attached manual Figure 6-7 The utility model provides a technical solution: a ring-shaped feeding distribution distributor. In order to further ensure that the amount of material discharged from the multiple branch pipes 3 is equal, a pressure sensor 12 is installed on the inner wall of the branch pipe 3. The pressure sensor 12 is used to monitor the material pressure in the branch pipe 3, so as to determine whether the amount of material in the multiple branch pipes 3 is equal. If the amount of material in the multiple branch pipes 3 is equal, the pressure values ​​of the pressure sensors 12 in the multiple branch pipes 3 are equal. If the amount of material in the multiple branch pipes 3 is not equal, the pressure values ​​of the pressure sensors 12 in the multiple branch pipes 3 are not equal. At this time, it proves that the material distribution is uneven and corresponding adjustments must be made.

[0038] Therefore, in the utility model, a pressurized pipe 13 is also provided on one side of the branch pipe 3, and a solenoid valve 14 and a filter element 15 are provided in the pressurized pipe 13. Multiple pressurized pipes 13 can be connected to a suction pump through a hose. When the pressure sensor 12 in one of the branch pipes 3 detects that the material pressure in the branch pipe 3 here is lower than the material pressure in other branch pipes 3, the suction pump and the corresponding solenoid valve 14 can be started, so that the suction force generated by the suction pump acts on the branch pipe 3, thereby having an attraction effect on the material, promoting the material in the feed barrel 1 to be discharged into this branch pipe 3, thereby achieving the purpose of automatically monitoring and controlling the material quantity balance in multiple branch pipes 3.

[0039] Furthermore, the pressurizing pipe 13 is located above the pressure sensor 12 , and the suction force generated has no effect on the material pressure at the lower end of the branch pipe 3 monitored by the pressure sensor 12 .

[0040] The filter element 15 is used to prevent the material from entering the pressurized pipe 13, ensuring that only suction can enter the pressurized pipe 13. The specific material of the filter element 15 can be determined according to the particle size of the material to ensure sufficient suction while preventing the material from entering the pressurized pipe 13. For example, when the material is 1-2CM particles, the filter element 15 can use a mesh plate with a pore size less than 0.8CM; when the material is powder, the filter element 15 can use a filter cotton block, etc. It can be adjusted according to actual usage requirements and will not be elaborated here.

[0041] It is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
