A raw material impurity removal device for vegetable oil processing

Abstract

This utility model relates to the field of vegetable oil processing technology, and more particularly to a raw material impurity removal device for vegetable oil processing, comprising: a screening box and a blowing device; dust removal holes are opened on both sides of the screening box; the blowing device is located on the side of the screening box with dust removal holes; a vibrating screen is provided on the side of the screening box near the ground; the vibrating screen has screen holes; the diameter of the dust removal holes is smaller than the diameter of the screen holes. Traditional impurity removal methods leave smaller impurities such as dirt and dust inside the impurity removal device before removal, which can easily lead to a large accumulation of such impurities inside the device over time, causing problems such as screen hole blockage and equipment damage. Compared with the prior art, this utility model opens dust removal holes on both sides of the screening box, and the blowing device is located at the dust removal holes, creating airflow inside the screening box.

Description

Technical Field

[0001] This utility model relates to the field of vegetable oil processing technology, and in particular to a raw material impurity removal device for vegetable oil processing. Background Technology

[0002] Vegetable oils are made from soybeans, peanuts, rapeseed, and other raw materials, with rapeseed being a crucial component. During rapeseed harvesting, impurities such as stems, leaves, and husks can easily become mixed in. Furthermore, during transportation, rapeseed can easily introduce impurities like mud, stones, and dust. Therefore, the purity of the raw materials directly impacts the quality and safety of the final product during vegetable oil processing. Consequently, pre-processing the raw materials to remove impurities is of paramount importance.

[0003] The current main method for removing impurities from rapeseed involves first placing the rapeseed on a sieve with larger openings to block larger impurities, and then transporting the rapeseed to a sieve with smaller openings to remove smaller impurities. This method leaves smaller impurities, such as dirt and dust, inside the removal device until they are removed. Over time, this can lead to a buildup of these impurities inside the device, causing sieve blockage and equipment damage. Utility Model Content

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] according to Figure 1-3 This utility model provides a raw material impurity removal device for vegetable oil processing, including: a screening box 1, a blowing device 2, an impurity removal structure 3, and a dust collection box 4.

[0019] Dust removal holes 11 are provided on both sides of the screening box 1. A blower 2 is installed on the side of the screening box 1 with the dust removal holes 11. A vibrating screen 12 is provided on the side of the screening box 1 closest to the ground. The vibrating screen 12 has screen holes. The diameter of the dust removal holes 11 is smaller than the diameter of the screen holes.

[0020] When it is necessary to remove impurities from rapeseed, the blower 2 is activated, and rapeseed is introduced from the top of the screening box 1. The rapeseed will fall onto the vibrating screen 12. Since there are dust removal holes 11 on both sides of the screening box 1, when the blower 2 is activated, it will blow air from one side of the screening box 1 and enter the screening box 1 through the dust removal hole 11 (hereinafter referred to as dust removal hole 11A) on that side. Then it will blow out from the dust removal hole 11 (hereinafter referred to as dust removal hole 11B) on the other side of the screening box 1, so that there is an airflow in the screening box 1 from the dust removal hole 11A to the dust removal hole 11B. When the rapeseed passes through this airflow, the lighter dust and dirt will be carried by the airflow and discharged from the dust removal hole 11B to the outside of the screening box, that is, separated from the rapeseed. The heavier rapeseed will fall onto the vibrating screen 12, and the vibrating screen 12 will remove the larger impurities. The above structure allows impurities such as dust and mud in the rapeseed to be quickly removed when they enter the screening box 1. Furthermore, the airflow makes it difficult for these impurities to remain in the screening box 1, thus preventing them from causing problems such as screen hole blockage and equipment damage.

[0021] The screening box 1 also includes: stacked plates 13. There are several stacked plates 13. The stacked plates 13 are arranged opposite each other on both sides of the screening box 1. The stacked plates 13 are arranged from the side of the screening box 1 away from the vibrating screen 12 to the other side. The stacked plates 13 are arranged alternately. The stacked plates 13 are inclined from the side away from the vibrating screen 12 to the other side. Dust removal holes 11 correspond to the stacked plates 13. The vibrating screen 12 is inclined from one side to the other. The screening box 1 has a waste discharge port 14 on the lower side of the vibrating screen 12. The waste discharge structure 3 is arranged on the side of the screening box 1 near the waste discharge port 14.

[0022] When rapeseed enters the screening box 1 and falls onto the vibrating screen 12, the falling speed is relatively fast, and the time spent in the airflow is short, which may result in some dust not being blown away by the airflow. This utility model is equipped with stacked plates 13. When rapeseed enters the screening box 1, it will first fall on the stacked plate 13 closest to the top of the screening box 1, and then fall down the inclined surface of the stacked plate 13 and fall onto another stacked plate 13. By staggering the stacked plates 13 on both sides of the screening box 1, the rapeseed will fall from the lower side of one stacked plate 13 and then fall on the higher side of another stacked plate 13. By utilizing the height, the rapeseed slides down the multiple stacked plates 13 in sequence, so that the rapeseed has enough time to pass before falling onto the vibrating screen 12, so that the rapeseed has enough time to remove dust and other impurities. Dust removal holes 11 correspond to the stacked plate 13, so that the dust removal holes 11 are set on both sides of the stacked plate 13, so that the airflow just passes through part of the space on the upper surface of the stacked plate 13, so that the rapeseed can be blown by the airflow when it slides on the stacked plate 13. When the rapeseed falls onto the vibrating screen 12, the vibrating screen 12 can be started, so that the rapeseed falls through the screen holes of the vibrating screen 12, while larger impurities are blocked on the vibrating screen 12. Since the vibrating screen 12 is inclined towards the impurity discharge port 14, the larger impurities will gradually move towards the impurity discharge port 14 during the vibration and fall into the impurity discharge structure 3 to be discharged, so as to prevent these impurities from accumulating on the vibrating screen 12 and requiring the equipment to be stopped for cleaning.

[0023] The dust collection box 4 is located on the side of the screening box 1 away from the blowing device 2. The dust collection box 4 corresponds to the dust removal hole 11. The dust collection box 4 is connected to the waste removal structure 3. The screening box 1 also includes a discharge structure 15. The discharge structure 15 includes a discharge plate 151. The discharge plate 151 is located on the side of the vibrating screen 12 closest to the ground. The discharge plate 151 has a waste removal hole. The diameter of the waste removal hole corresponds to the diameter of the dust removal hole. The discharge plate 151 is inclined from the side away from the ground to the other side. The discharge structure 15 also includes a waste removal plate 152. The waste removal plate 152 is inclined from the side away from the ground to the other side. The higher side of the waste removal plate 152 is connected to the lower side of the discharge plate 151. The screening box 1 has a waste removal outlet 16 near the lower side of the waste removal plate 152. The waste removal outlet 16 corresponds to the waste removal structure 3.

[0024] After the rapeseed passes through the sieve holes of the vibrating screen 12, it will fall onto the discharge plate 151. Since there are some impurities with higher density such as stones in the rapeseed, these impurities are small but heavy and difficult to be blown away by the airflow. They will also pass through the sieve holes and fall onto the discharge plate 151 along with the rapeseed. However, these impurities will not stick to the inside of the impurity removal device. Impurity discharge holes can be opened on the discharge plate 151 so that these impurities fall into the impurity discharge holes, and the rapeseed will be discharged normally. When the impurities fall into the impurity discharge holes, they will fall onto the impurity discharge plate 152 and slide down the inclined impurity discharge plate 152 into the impurity discharge structure 3. This utility model also provides a dust collection box 4 on the side of the screening box 1 away from the blowing device 2, so that after the dust is blown out from the dust removal hole 11B, it will directly enter the dust collection box 4 to prevent the dust from spreading into the air and affecting the working environment. When the dust enters the dust collection box 4, the airflow will also enter, which can drive the dust out from the outlet of the dust collection box 4 and enter the impurity removal structure 3. By connecting each impurity discharge outlet with the impurity removal structure 3, the impurities can be collected and processed in a unified manner.

[0025] Working principle and usage process of this utility model:

[0026] When it is necessary to remove impurities from rapeseed, first turn on the blower 2 and the vibrating screen 12, then introduce rapeseed from the top of the screening box 1. After entering the screening box 1, the rapeseed falls onto the first stacked plate 13 and slides down the inclined surface of the stacked plate 13. At the same time, the air blown out by the blower 2 enters the screening box 1 through the dust removal hole 11A, and then blows away the dust, dirt and other impurities adhering to the rapeseed, and blows them out through the dust removal hole 11B. The blown-out impurities will enter the dust collection box 4, and then enter the impurity discharge structure 3. After the rapeseed falls from the stacked plate 13 onto the vibrating screen 12, the vibration of the vibrating screen 12 causes the rapeseed to fall through the screen holes of the vibrating screen 12 onto the discharge plate 151. Larger impurities are blocked on the vibrating screen 12 and gradually move towards the impurity discharge port 14 through the vibrating screen 12, and finally fall into the impurity discharge structure 3. After the rapeseed falls onto the discharge plate 151, it passes through the inclined outlet of the discharge plate 151. Some impurities such as stones fall onto the discharge plate 152 through the discharge hole of the discharge plate 151, and then reach the discharge outlet 16 through the inclined discharge plate 152, entering the discharge structure 3. Finally, all impurities are discharged together through the discharge structure 3.

[0027] In summary, this utility model creates airflow inside the screening box by opening dust removal holes on both sides of the screening box and placing the blowing device at the dust removal holes. When rapeseed passes through, lighter dust, dirt and other impurities are carried out of the dust removal holes by the airflow, thus avoiding dust adhering inside the impurity removal device and causing problems such as screen hole blockage and equipment damage.
