Description

Technical Field

[0001] This utility model relates to the field of rice cleaning technology, and in particular to a vibrating cleaning screen for separating broken rice. Background Technology

[0002] After the rice milling process is completed, although brown rice has basically been transformed into white rice, some new impurities may be mixed in during this process, such as debris produced by the wear and tear of the rice milling equipment itself, a small amount of unremoved brown rice bran, or other fine particles.

[0003] Therefore, it is necessary to use a vibrating cleaning screen to screen out and remove impurities mixed in with rice, thereby improving the quality of rice, making it cleaner and tidier in appearance, better in taste, and more in line with the corresponding quality standards, thus improving the quality and competitiveness of finished rice products in the market.

[0004] When using a vibrating cleaning screen to sieve rice, the bran of the brown rice can easily get stuck in the filter holes, causing blockages and some problems:

[0005] First, the effective screening area of ​​the screen is reduced due to clogging, which greatly reduces screening efficiency and significantly decreases the amount of rice that can be processed per unit time, seriously affecting the production schedule.

[0006] Secondly, due to the clogging of the brown rice bran, the fine impurities that should have been screened out may not be separated properly due to the clogging of the screen, resulting in excessive impurities in the finished rice product, affecting the purity and quality of the rice.

[0007] Furthermore, if the blockage problem is not resolved in time, it will increase the load on the vibrating cleaning screen, leading to higher energy consumption and increased production costs. Utility Model Content

[0008] The purpose of this invention is to provide a vibrating cleaning screen for separating broken rice grains. By using this device, the above-mentioned problems can be solved.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rice breakage separation vibrating cleaning screen, including a cleaning box, vibrating springs and a vibrating motor. Vibrating springs are provided at the front and rear ends of both sides of the cleaning box, and a vibrating motor is provided at the middle position of both sides of the cleaning box. A vibrating screen is provided inside the cleaning box, and a guide inclined block is provided at the bottom of the cleaning box. A discharge port one is provided at the rear end of the cleaning box, located at the lowest position of the vibrating screen. A discharge port two is provided below the discharge port one, located at the rear end of the cleaning box and at the lowest position of the guide inclined block. A feeding pipe is provided at the front end of the top of the cleaning box, and a blowing component is provided at the front end of the cleaning box. A suction component is provided at the rear end of the feeding pipe.

[0010] The top of the injection pipe is equipped with an injection hopper, the rear end of the injection pipe is provided with a side groove, and the front end of the injection pipe is provided with an inclined groove. The inclined groove is located below the side groove, and the inclined groove is inclined upward and faces the side groove. A baffle net is provided at the highest point of the inclined groove.

[0011] The blowing assembly includes a blower installed at the front end of the cleaning box, an air duct installed at the top of the blower, an air guide plate at the inclined end of the front end of the injection pipe, and the air inlet end of the air guide plate connected to the air duct.

[0012] The suction assembly includes a waste box located at the rear end of the injection pipe, a fan installed at the rear end of the waste box, a connecting pipe installed at the front end of the waste box, one end of the connecting pipe being connected to a side channel, and a filter screen installed inside the waste box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model provides a vibrating cleaning screen for separating rice bran. By effectively separating most of the brown rice bran before the rice enters the subsequent key screening stage, it can prevent the brown rice bran from clogging the screen, thus reducing the effective screening area and significantly decreasing the screening efficiency. This results in a significant decrease in the amount of rice that can be processed per unit time, seriously affecting the production schedule. Secondly, filtering the brown rice bran can prevent fine impurities that should be screened out from failing to separate properly due to screen blockage, which could lead to excessive impurities in the finished rice product, affecting the purity and quality of the rice. Finally, it can reduce the load on the vibrating cleaning screen to a certain extent. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0023] Combination Figures 1 to 5 As shown, this utility model discloses a rice breakage separation vibrating cleaning screen, including a cleaning box 1, vibrating springs 2, and a vibrating motor 3. Vibrating springs 2 are provided at the front and rear ends of both sides of the cleaning box 1, and vibrating motor 3 is provided at the middle position of both sides of the cleaning box 1. A vibrating screen 14 is provided inside the cleaning box 1, and a guide inclined block 13 is provided at the bottom of the cleaning box 1. A discharge port 11 is provided at the rear end of the cleaning box 1, located at the lowest position of the vibrating screen 14. A discharge port 12 is provided below the discharge port 11, located at the rear end of the cleaning box 1 and at the lowest position of the guide inclined block 13. A feeding pipe 4 is provided at the front end of the top of the cleaning box 1, and a blowing component is provided at the front end of the cleaning box 1. A suction component is provided at the rear end of the feeding pipe 4.

[0024] The top of the injection pipe 4 is provided with an injection hopper 41, the rear end of the injection pipe 4 is provided with a side groove 42, the front end of the injection pipe 4 is provided with an inclined groove 43, the inclined groove 43 is located below the side groove 42, the inclined groove 43 is inclined upward and faces the side groove 42, and a baffle net 44 is provided at the highest point of the inclined groove 43.

[0025] The blowing assembly includes a blower 5 installed at the front end of the cleaning box 1. An air duct 51 is installed at the top of the blower 5. An air guide plate 52 is provided at the end of the inclined groove 43 at the front end of the injection pipe 4. The air inlet end of the air guide plate 52 is connected to the air duct 51.

[0026] The suction assembly includes a waste box 6 located at the rear end of the injection pipe 4. A fan 61 is installed at the rear end of the waste box 6, and a connecting pipe 62 is installed at the front end of the waste box 6. One end of the connecting pipe 62 is connected to the side groove 42, and a filter screen 63 is installed inside the waste box 6.

[0027] Working principle:

[0028] Start the blower 5, exhaust fan 61 and vibration motor 3. Use the blower 5 to blow gas into the inclined chute 43 through the air duct 51 and the air guide plate 52. The gas is blown upward into the injection pipe 4.

[0029] The milled rice is fed into the feeding hopper 41 and enters the feeding pipe 4. It is blown upwards by the gas. Under the action of the gas, the brown rice bran mixed in with the milled rice is blown upwards to the side groove 42. The exhaust fan 61 generates sufficient suction and, together with the connecting pipe 62, sucks the brown rice bran blown to the side groove 42 into the waste box 6. The filter screen 63 adsorbs the brown rice bran on its surface and collects it. In this way, the brown rice bran mixed in with the milled rice is removed to a certain extent, reducing the problem of brown rice bran getting stuck in the filter holes and causing filter blockage.

[0030] After the rice bran is removed, the milled rice falls onto the vibrating screen 14. When the vibrating cleaning screen is working, the eccentric block inside the vibrating motor 3 generates a periodically changing centrifugal force as the motor rotates, causing the motor to vibrate and transmitting the vibration force to the cleaning box 1. The vibrating spring 2 supports the cleaning box 1 and the weight of the material, buffers the vibration, and protects the foundation. In conjunction with the vibrating motor 3, the spring 2 adjusts the vibration frequency and amplitude of the vibrating screen 14 according to its elastic coefficient, so that the vibrating screen 14 vibrates stably. The material jumps on the vibrating screen 14. Large particles such as rice are difficult to pass through the screen holes due to their size, while small particles such as impurities and rice fragments can fall down, thereby achieving the purpose of cleaning.
