[0002] Rapeseed oil is what we commonly call rapeseed oil, also known as rapeseed oil, coriander oil, canola oil, sesame oil, and canola oil. It is an edible oil squeezed from rapeseed. It is one of the main edible oils in my country, mainly produced in the Yangtze River Basin and southwest and northwest areas, and its output ranks first in the world. Rapeseed oil is obtained after pressing, and it still contains a lot of impurities, so it needs to be processed. Generally, rapeseed oil crude oil screening refers to the process of screening and separating the crude rapeseed oil extracted initially. The residual solid impurities and sediments are removed by crude oil screening, thereby improving the quality of the oil and making it purer. Common screening methods include filtration, centrifugal separation and sedimentation. Generally speaking, filtration is the most commonly used method. However, existing filtration equipment still has defects. After the crude oil is filtered, a lot of impurities remain on the filter screen, which is difficult to remove manually. In addition, the impurities also assist part of the oil on the upper part, and direct removal will cause waste.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0023] like Figure 1-Figure 5 As shown, the crude oil separation device for rapeseed oil production includes a fixed bracket 1, a screw 2, a drive box 6, a screening mechanism 4 and a scraping mechanism 5. The upper part of the fixed bracket 1 is provided with a screening mechanism 4, and the screening mechanism 4 includes a material trough 41, a screening trough 44, a screening net 46, a first discharge port 45 and a second discharge port 42. The material trough 41 is a rectangular hollow structure with an upper opening, and the material trough 41 is provided with a screening trough 44 inside, and the screening trough 44 is provided with a screening net 46 inside. , first discharge ports 45 are provided on both sides of the screening trough 44, and the first discharge ports 45 are provided corresponding to the second discharge ports 42 on the trough 41; a scraper mechanism 5 is provided on the upper part of the trough 41, and the scraper mechanism 5 includes a movable bracket 51, a telescopic rod 53 and a scraper plate 55, and the movable bracket 51 is connected to the screw 2 on the fixed bracket 1 through a screw hole 56 at the bottom, and a telescopic rod 53 and a scraper plate 55 connected to the telescopic rod 53 are provided on the upper part of the movable bracket 51.

[0024] It should be noted that during the processing of rapeseed oil, it is generally necessary to undergo primary rapeseed screening, pressing, crude oil filtration and finished oil collection. Generally, we use physical screening to filter the crude oil. After long-term use, we found that the existing screening equipment adheres to the screen after filtering out impurities, and the impurities contain oil, which is difficult to clean. Therefore, a device that can automatically remove impurities is designed to improve the applicability and convenience of the equipment. We designed a screening trough 44 inside the material trough 41, with a built-in screening net 46. The crude oil enters the screening net 46 for filtration, and the impurities mixed in the crude oil can be filtered on the surface of the screening net 46, and are introduced into the first discharge port 45 through the scraping mechanism 5, and fall into the filter tank 47 inside the second discharge port 42. Not only can the impurities be automatically discharged, but the impurities can also be left to stand and filter again after entering the filter tank 47. After the filtration is completed, it is convenient for the operator to export it, which is convenient for use.

[0025] It needs to be further explained that, in order to realize automatic scraping and discharge of impurities attached to the screening net 46, our mobile bracket 51 is set on the screw 2 phase, and is moved under the drive of the drive box 6, and a telescopic rod 53 and a scraper plate 55 connected to the telescopic rod 53 are arranged inside the mobile bracket 51. After the scraper plate 55 contacts the screening net 46, it moves with the mobile bracket 51, and during the movement, the impurities are introduced into the first discharge port 45 on both sides of the screening net 46, thereby realizing the purpose of automatic scraping.

[0026] like Figure 3 and Figure 4 As shown, the first discharge port 45 is arranged on the side of the screening net 46. The screening net 46 is a semi-arc net, and a plurality of through holes are arranged on the upper part of the screening net 46.

[0027] It should be noted that, since the crude oil is relatively viscous, the screening net 46 adopts a semi-arc structure and is in a concave state when placed, which can carry more crude oil and facilitate filtering.

[0028] It should be further explained that, in order to match the screening mesh 46, the bottom of our scraper plate 55 also adopts a semi-arc structure, which matches the shape of the screening mesh 46 to facilitate scraping.

[0029] like Figure 3 and Figure 4 As shown, an L-shaped filter tank 47 is disposed inside the second discharge port 42 , a plurality of through holes 43 are disposed at the bottom of the filter tank 43 , and the edge of the filter tank 43 is connected to the first discharge port 45 .

[0030] It should be noted that the filter tank 47 is arranged at the second discharge port 42 on the side of the material tank 41, and is used to receive impurities scraped off the screening net 46 for storage and static filtration. It can not only guide the oil into the interior of the material tank 41 during the static process, but also facilitate the operator to export it.

[0031] like Figure 3 and Figure 5 As shown, the scraper plate 55 is arranged at one end of the telescopic rod 53, and a pressure spring 54 is arranged on the outer wall of the telescopic rod 53 to form an elastic structure; the scraper plate 55 is a triangular rectangular plate, and a rubber sheet is arranged at the bottom of the scraper plate 55, which is arranged at the connection between the rubber sheet and the screening net 46 inside the screening slot 44.

[0032] It should be noted that a pressure spring 54 is arranged on the upper part of the telescopic rod 53 to form an elastic structure, so that when the scraper plate 55 at the lower part contacts the surface of the screening net 46, partial elastic force can be generated, and there is space for expansion and contraction, so that the scraper plate 55 always relies on the pressure spring 54 to contact the surface of the screening net 46. In addition, in order to facilitate scraping, impurities are transported to the first discharge port 45 on both sides. The scraper plate 55 is arranged in a triangular shape to facilitate the pushing of impurities.

[0033] like Figure 1 and Figure 2 As shown, the screw 2 is connected to the fixed bracket 1 through the bearing seat 3, and one end of the bearing seat 3 is connected to the drive box 6; the interior of the drive box 6 is provided with synchronous wheels respectively connected to one end of the screw 2, and the two synchronous wheels are connected through a synchronous belt, and the outside of the drive box 6 is provided with a drive motor 7, and the output shaft of the drive motor 7 is connected to a screw 2 through a coupling; the drive box 6 is arranged on a fixed plate 8 at one end of the fixed bracket 1.

[0034] It should be noted that the entire screw rod 2 is connected to the driving box 6 via a connecting piece, which facilitates the driving of the screw rod 2, thereby driving the entire upper movable bracket 51 to move, thereby realizing automatic scraping.

[0035] like Figure 1 and Figure 3 As shown, a discharge port 9 is provided at the bottom of the material trough 41, and a valve is provided on the discharge port 9.

[0036] It should be noted that the outlet 9 provided at the bottom of the trough 41 facilitates the outlet of the filtered oil. The above describes the embodiments of the utility model in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the utility model.
