Description
Technical Field
[0001] The utility model relates to the technical field of rapeseed oil processing equipment, in particular to a continuous screening device for rapeseed oil processing. Background Art
[0002] Rapeseed oil is a vegetable oil extracted from rapeseed, and is often used in multiple cooking methods such as frying, stir-frying, and deep-frying. During the processing of rapeseed oil, it is necessary to select high-quality rapeseed, clean it, and remove impurities. It is crushed by crushing equipment, and then heated and pressed to obtain crude oil. The crude oil contains more impurities, and the finished rapeseed oil is obtained after filtering. Rapeseed contains more impurities and empty rapeseed, which need to be removed before pressing. Generally, screening is carried out using a screening net. This method can only remove straw impurities in rapeseed, but cannot screen out empty rapeseed, and the effect is not ideal. Therefore, we designed a device that can remove impurities and empty rapeseed from rapeseed at the same time to improve the screening efficiency. Utility Model Content
[0003] In view of the technical problems existing in the background technology, the utility model provides a continuous screening device for rapeseed oil processing, which can continuously screen rapeseed, remove impurities and empty rapeseed in the rapeseed at the same time, and improve the screening efficiency.
[0004] The technical implementation scheme of the utility model is:
[0005] A continuous screening device for rapeseed oil processing comprises a fixed frame, a screening trough and a screening mechanism.

[0008] Optionally, the pneumatic separation mechanism includes a material guiding bottom plate, a guiding guard plate, a connecting plate, a blower, and a material guiding groove.

During the vibration process, the rapeseeds in the screening trough are screened. For the convenience of screening, the left and right ends of the screening trough are arranged in an inclined manner, which is convenient for the rapeseeds to pass through and discharge during vibration. Moreover, the inside of the screening trough is also inclined in the front and back directions.

Specific embodiments
[0024] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the accompanying drawings of the present utility model, and they do not specifically limit the present utility model.
[0025] As Figures 1 - 4 shown, a continuous screening device for rapeseed oil processing includes a fixed frame 1, a screening trough 2 and a screening mechanism 6. The fixed frame 1 is a rectangular frame structure. A screening trough 2 is arranged on the upper part of the fixed frame 1, and a screening mechanism 6 is arranged inside the screening trough 2. The screening mechanism 6 includes a screening trough 607, a fixing plate 603, a telescopic rod 604, an adjusting rod 605 and a driving mechanism. The bottom of the fixing plate 603 is connected to the connecting platform 8 inside the screening trough 2 through the telescopic rod 604. The upper part of the fixing plate 603 is connected to the screening trough 607 through the adjusting rod 605. The bottom of the fixing plate 603 is connected to the driving mechanism. The screening trough 607 is inclined and arranged on the upper part of the fixing plate 603. The discharge ends of the screening trough 607 are respectively provided with a first discharge trough 4 and a second discharge trough 5. The other end of the first discharge trough 4 is connected to the air separation mechanism 7.
[0026] It should be noted that our rapeseed is generally purchased from farmers. Due to the primitive processing technology, there are more straw impurities and empty rapeseed inside the rapeseed. If they are not screened out, it will affect the effect of subsequent heating and pressing. However, the existing screening method generally uses vibration to remove impurities on the upper part through a screening net. At that time, it was impossible to remove the empty rapeseed. Therefore, we designed a method that relies on gravity and can be screened by vibration according to different mass specific gravity. Among them, the screening slot 2 is set on the upper part of the fixed frame 1 and A screening mechanism 6 is arranged inside the screening trough 2, which can drive the upper screening trough 607 to vibrate through a driving mechanism, and the left and right sides of the screening trough 607 are inclined. During the vibration process, the rapeseed can move to the lower end, and in order to separate the impurities and empty rapeseed in the rapeseed according to the difference in gravity, the bottom of the screening trough 607 is also inclined. During the vibration process, the impurities and empty rapeseed are lighter in texture and will float to the upper part. Since the bottom of the screening trough 607 is in an inclined state, the impurities and empty rapeseed will enter the first discharge trough 4 to achieve screening.
[0027] like Figures 3 - 5 As shown, the adjustment rod 605 includes a bottom sleeve 601, a fine-tuning rod 602, a fixing ear 612 and a limiting hole 613. One end of the fine-tuning rod 602 is movably arranged inside the bottom sleeve 601, and the other end of the fine-tuning rod 602 is movably connected to a connecting block 606 on the screening trough 607 through the fixing ear 612. A rectangular opening is arranged on the outer wall of the bottom sleeve 601, and a plurality of limiting holes 613 are arranged inside the rectangular opening.
[0028] It should be noted that in order to achieve an inclined setting of the entire screening trough 607 on the fixed plate 603 with an adjustable inclination angle, the bottom of the screening trough 607 is movably connected to the bottom sleeve 601 on the fixed plate 603 through a fine-tuning rod 602, and is fixed by a limiting pin inside the limiting hole 613. The height of the entire fine-tuning rod 602 can be adjusted as needed, thereby adjusting the angle.
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the driving mechanism includes an auxiliary rotating wheel 609, a rotating shaft, a cam 610 and a driving motor 611 arranged at the bottom of the fixed plate 603. The rotating shaft is arranged inside the screening slot 2, and a cam 610 is arranged on the rotating shaft, and the cam 610 is connected to the auxiliary rotating wheel 609; one end of the rotating shaft is connected to the driving motor 611 through a coupling.
[0030] It should be noted that in order to achieve the vibration of the screening trough 607, we adopt the cam method. The driving motor 611 drives the cam 610 to rotate. The cam 610 is in contact with the auxiliary rotating wheel 609 on the fixed plate 603. Under the continuous rotation of the cam, the vibration is realized in cooperation with the telescopic rod 604 and the pressure spring 608.
[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 shown, the winnowing mechanism 7 includes a material guiding bottom plate 704, a guiding guard plate 705, a connecting plate 702, a blower 703 and a material guiding trough 707. The material guiding bottom plate 704 and the guiding guard plate 705 are both arranged inside the screening trough 2. The guiding guard plate 705 is arranged above the material guiding bottom plate 704 to form an air guiding channel structure. The material guiding trough 707 is arranged at the feeding port of the screening trough 2, and the upper part of the material guiding trough 707 is correspondingly arranged opposite to the first discharge trough 4. The connecting plate 702 is connected to one end of the screening trough 2 through a connecting rod 701, and a blower 703 corresponding to the material guiding trough 707 is arranged above the connecting plate 702. An air outlet 706 is arranged at the other end of the screening trough 2, and a connecting ring and a collecting cloth bag connected to the connecting ring are arranged at the edge of the air outlet 706.
[0032] It should be noted that the empty rapeseeds and impurities screened out by the screening trough 607 will contain smaller but relatively plump grains inside. They are only screened out because of their light texture. In order to recover this part of rapeseeds, we designed a winnowing mechanism 7. When the material falling from the first discharge trough 4 enters the material guiding trough 707, it can be winnowed by the blower 703. The impurities and empty rapeseeds are light in texture and can be separated by the wind. At this time, the impurities and empty rapeseeds enter the collecting cloth bag at the air outlet 706 through the guiding trough formed by the guiding guard plate 705. The relatively plump rapeseeds fall out from the bottom discharge port of the guiding trough and are collected.
[0033] As Figure 1 and Figure 7 shown, an elastic structure is formed by arranging a pressure spring 608 on the outer wall of the telescopic rod 604. The screening trough 607 is a rectangular cavity structure with an open upper part and one end. The bottom of the screening trough 607 is arranged in an inclined structure, and a partition plate 3 is arranged at the discharge port of the screening trough 607.
[0034] It should be noted that the telescopic rod 604 is used to connect the fixed plate 603 and the connecting platform 8. A pressure spring 608 is designed on it to form an elastic structure, and the vibration is realized in cooperation with the driving mechanism. The setting of the partition plate 3 at the discharge port of the screening trough 607 can separate the screened rapeseeds and enter the first discharge trough 4 and the second discharge trough 5.
[0035] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present utility model.
