Description
Technical Field
[0001] The utility model belongs to the technical field of rice processing, and particularly relates to a feeding and filtering device for rice processing. Background Technique
[0002] Rice refers to the edible rice obtained after removing the husk and bran from paddy. Rice is one of the most important food crops in the world, and is widely planted and consumed. Rice is mainly for human consumption and is also an important staple food in many cultures. The rice processing process is to first dehull the paddy and then separate the rice. After separation, processes such as selection, whitening, and brown rice processing are carried out. The rice obtained from the separation process often still contains impurities such as rice bran, and filtration is still required during subsequent processing feeding to ensure the quality of subsequent processing.
[0003] When processing rice, it is necessary to remove the impurities and a small part of the rice husks carried by the rice. Most of the existing rice feeding and filtering devices can only conduct preliminary filtration on the rice and perform air separation on the rice husks inside through a blower. During the air separation process, the side blowing method is mostly used. Due to the obstruction of the rice on one side, the filtering effect is very limited, and this process needs to be carried out continuously for many times to filter thoroughly, resulting in low filtering efficiency. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is that the existing filtering device will be blocked by a large number of overlapping rice during the air separation and filtration of rice, so the filtering efficiency is low.
[0005] To solve the above technical problem, the technical solution provided by the utility model is: a feeding and filtering device for rice processing, including a barrel body, a feeding hopper is arranged at the top of the barrel body, an aggregate hopper is arranged inside the barrel body below the feeding hopper, a blanking device is arranged at the bottom of the aggregate hopper, a distribution plate is arranged inside the barrel body below the blanking device. The distribution plate is in a herringbone structure as a whole, and a sieve mesh is arranged at the inclined surface of the herringbone structure of the distribution plate. A blower perpendicular to the sieve mesh is fixed inside the distribution plate through a bracket. A collection chamber is arranged in the barrel body in the vertical direction of the blower, and a plurality of exhaust plates are arranged in the vertical direction of the blower in the collection chamber. A slag discharge port is arranged at one side of the bottom of the collection chamber; a blanking port is formed between the two ends of the lower part of the distribution plate and the barrel body, and a magnet is arranged at the blanking port of the distribution plate. A receiving box is inserted at the middle position of the barrel body corresponding to the distribution plate. An aggregate trough is arranged at the bottom of the barrel body below the blanking port, a spiral feeding rod is arranged in the middle of the aggregate trough, and a discharge port is arranged at one end of the barrel body corresponding to the spiral feeding rod.
[0006] As an improvement, the shape of the aggregate hopper matches the inner shape of the barrel body, and the aggregate hopper is an inverted frustum cone structure.
[0007] As an improvement, the whole of the blanking device is of a hollow cylindrical structure, and a plurality of material distributing plates are connected inside the blanking device through a rotating shaft, and one end of the rotating shaft is connected with a first motor.
[0008] As an improvement, the shapes of the plurality of material distributing plates match the shape inside the blanking device, and the plurality of material distributing plates are arranged at equal angles around the rotating shaft. A feeding port is arranged at the bottom of the blanking device, and the shape of the feeding port matches the shape between two adjacent material distributing plates.
[0009] As an improvement, the collecting cavity protrudes from the outer wall of the barrel body, and the collecting cavity is communicated with the inside of the barrel body. The bottom of the collecting cavity is an inclined plane, and the height of the collecting cavity at the slag discharge port is the lowest.
[0010] As an improvement, the direction between the material dividing plate and the blanking device is perpendicular, and the shape of the material dividing plate matches the shape inside the barrel body.
[0011] As an improvement, the material receiving box is located at the middle position of the herringbone structure of the material dividing plate, and both sides of the material receiving box are abutted against the magnet positions of the material dividing plate.
[0012] As an improvement, the aggregate trough is a slope with a gradually decreasing height from both ends to the middle, and the spiral feeding rod is located at the lowest position above the aggregate trough. A second motor is arranged on the side of the spiral feeding rod away from the discharge port.
[0013] The advantages of the present utility model compared with the prior art are as follows:
[0014] 1. This filtering device caches the incoming rice through the aggregate hopper arranged inside the barrel body, and reduces the quantity of rice discharged simultaneously through the blanking device, thereby reducing the shielding received simultaneously during the subsequent air separation process. A material dividing plate is arranged below the blanking device, which can further divide the rice, and the rice is air-separated through the fan inside the material dividing plate. The lighter part moves with the wind into the collecting cavity, and after the wind is discharged from multiple exhaust plates, it drops into the collecting cavity for collection, thereby reducing the quantity of rice in a single air separation, further reducing the shielding received in a single air separation filtration, and increasing the efficiency of air separation;
[0015] 2. This filtering device is provided with magnets at the bottom of the material dividing plate, which can adsorb and filter items such as metals doped in the rice. At the same time, the sieve meshes on both sides of the material dividing plate can not only pass air but also filter the rice to a certain extent, enabling smaller debris to be filtered into the material receiving box inside the material dividing plate.

The blanking device 4 is an overall hollow cylindrical structure, and a plurality of material distributing plates 19 are connected inside the blanking device 4 through a rotating shaft 18.

The plurality of material distributing plates 19 match the shape inside the blanking device 4, and the plurality of material distributing plates 19 are arranged at equal angles with the rotating shaft 18 as the center. A feeding port 21 is arranged at the bottom of the blanking device 4, and the feeding port 21 matches the shape between two adjacent material distributing plates.
[0025] In the present utility model, a material distributing plate 5 is arranged below the blanking device 4 inside the barrel body 1. The material distributing plate 5 is perpendicular to the direction between the blanking device 4, and the material distributing plate 5 matches the shape inside the barrel body 1. The material distributing plate 5 is an overall herringbone structure, and a screen 6 is arranged at the inclined surface of the herringbone structure of the material distributing plate 5. A fan 8 perpendicular to the screen 6 is fixed inside the material distributing plate 5 through a support 7.

[0026] In the present utility model, blanking openings 12 are formed between the two ends of the lower part of the material distributing plate 5 and the barrel body 1, and magnets 13 are arranged at the blanking openings 12 of the material distributing plate 5. A receiving box 14 is inserted at the middle position of the barrel body 1 corresponding to the material distributing plate 5.
