Description

Technical Field

[0001] The utility model belongs to the technical field of rapeseed oil processing, and particularly relates to a pressing and filtering device for rapeseed oil. Background Art

[0002] Rapeseed oil, also known as rapeseed oil and coriander oil, is an edible oil squeezed from rapeseed. With the development of society and technological progress, machines have gradually replaced manual labor, and traditional manual oil pressing has also been replaced by machines. Various types of oil presses have emerged in an endless stream.

[0003] In the process of producing rapeseed oil, rapeseed needs to be squeezed and filtered. Although the existing rapeseed oil squeezing and filtering devices can meet the basic needs of squeezing and filtering rapeseed, in the process of filtering the mixture of oil residue and oil after squeezing, the filter structure can usually only be vibrated by the vibration structure to filter the mixture of oil residue and oil, but it is not convenient to filter the mixture of oil residue and oil. As a result, some oil mixed in the oil residue is difficult to filter out, resulting in a technical problem that the oil cannot be filtered sufficiently.

[0004] For example, the patent document with the announcement number CN213624031 U discloses a squeezing and filtering device for rapeseed oil production. In the technical solution of this patent, under the action of a stepping motor, the driving wheel rotates, thereby driving the driven wheel to rotate, thereby rotating the cam. Under the interference cooperation between the cam and the contact plate, the filter frame is driven to swing left and right along the rotating shaft, thereby filtering the mixture of oil residue and oil. However, since the mixture of oil residue and oil cannot be press-filtered, the oil retained in the oil residue cannot be effectively filtered, which affects the thoroughness of the oil filtration treatment, and therefore cannot fully meet people's usage needs.

[0035] like Figure 4As shown, the drive module includes two drive motors 201 arranged on the rear side wall of the processing box 101, and the output shafts of the two drive motors 201 are respectively provided with driving pulleys 202, and the rear ends of the two connecting shafts 105 are respectively provided with driven pulleys 203 adapted to the driving pulleys 202, and transmission belts 204 are respectively provided between the two driving pulleys 202 and the corresponding driven pulleys 203.

[0036] like Figure 3 As shown, a guide slot 301 is provided on the inner wall of the processing box 101 , and a guide slider 302 slidably connected to the guide slot 301 is provided on the outer wall of the mounting frame 109 .

[0037] like Figure 2 、 Figure 3 and Figure 5 As shown, the left and right sides of the mounting frame 109 are respectively provided with connecting chutes 305 with open front ends, and the left and right sides of the filter cartridge 110 are respectively provided with connecting slides 306 that are slidably connected to the connecting chutes 305. The connecting chutes 305 are also provided with first hand-tightening bolts 307 for threading and fixing the connecting slides 306. The connecting slides 306 are provided with first threaded connection holes that match the first hand-tightening bolts 307. After the filter column and the mounting frame 109 are slidably connected together through the connecting chutes 305 and the connecting slides 306, the connection between the connecting chutes 305 and the connecting slides 306, as well as the connection between the filter cartridge 110 and the mounting frame 109, can be flexibly fixed by the cooperation between the first hand-tightening bolts 307 and the first threaded connection holes.

[0038] like Figure 1 and Figure 2 As shown, the cover 119 is clipped and fixed to the front end of the processing box 101. The processing box 101 is provided with an inlet and outlet 309 that are compatible with the cover 119. The cover 119 is also provided with a second hand-tightening bolt 310 for threadedly securing the processing box 101. The processing box 101 is provided with a second threaded connection hole that is compatible with the second hand-tightening bolt 310. By simply clipping and fixing the cover 119 to the front end of the processing box 101, and then passing the second hand-tightening bolt 310 through the side wall of the cover 119 and connecting with the second threaded connection hole, the connection between the cover 119 and the processing box 101 can be flexibly fixed. The connection between the cover 119 and the processing box 101 can be released by simply separating the second hand-tightening bolt 310 from the second threaded connection hole, and the cover 119 can then be removed from the processing box 101.

[0039] like Figure 1 and Figure 2As shown, the box cover 119 is also provided with a handle 311 and a transparent observation window 312. By means of the handle 311, the box cover 119 can be easily moved, and the clamping fixation of the box cover 119 and the processing box 101 can be easily realized or released.

[0040] The user can first remove the box cover 119 from the processing box 101, and then pass the filter cartridge 110 through the inlet and outlet 309, so that the connecting slide 306 is slidably connected with the connecting slide 305, and then the first hand-tightening bolt 307 can be passed through the side wall of the connecting slide 305 and screwed to the second threaded connection hole to flexibly fix the filter cartridge 110 to the mounting frame 109, and then the box cover 119 can be fixed to the processing box 101 again.

[0041] After that, the two driving motors 201 can be started, and the two connecting shafts 105 can be rotated through the cooperation of the active pulley 202, the driven pulley 203 and the transmission belt 204, so that the two grinding rollers 106 are ready to grind the rapeseed. At the same time, multiple vibration motors 111 can be started, and with the cooperation of multiple springs 108, and the sliding guide cooperation of the guide slider 302 and the guide chute 301, the mounting frame 109 and the filter drum 110 are vibrated to prepare for screening the mixture of oil residue and oil, and the guide hopper 113 can vibrate with the mounting frame 109, so as to prepare to receive the mixture of ground oil residue and oil.

[0042] After that, the rapeseed can be gradually added to the processing box 101 through the feed hopper 104. After the oil residue falls onto the two grinding rollers 106, it will be ground by the two grinding rollers 106 to become a mixture of oil residue and oil. Most of the mixture of oil residue and oil will pass through the two grinding rollers 106 and directly fall into the guide hopper 113. A small part of the mixture of oil residue and oil will adhere to the outer wall of the grinding roller 106, but the scraper plates 120 on the left and right sides will scrape and clean the small part of the mixture of oil residue and oil adhering to the outer wall of the grinding roller 106 and make it fall into the guide hopper 113.

[0043] Since the guide hopper 113 can vibrate under the drive of the mounting frame 109, the mixture of oil residue and oil can be smoothly and efficiently introduced into the filter cartridge 110. During the vibration operation, the filter cartridge 110 can smoothly perform vibration screening on the mixture of oil residue and oil, so that the oil passes through the filter holes of the filter cartridge 110 and falls into the lower end of the interior of the processing box 101, and leaves the processing box 101 through the discharge pipe 102. The oil residue will be retained in the filter cartridge 110 because it cannot pass through the filter holes of the filter cartridge 110.

[0044] After a period of time, when a large amount of mixture of oil residue and oil is retained in the filter cartridge 110, the addition of new rapeseed to the feed hopper 104 can be stopped, and the vibration motor 111 can be stopped. Then, the output shaft of the first telescopic push rod 115 is extended downward by a certain length, and the pressing plate 118 is moved downward by a certain distance. The mixture of oil residue and oil remaining in the filter cartridge 110 is subjected to filter pressure treatment, so that the oil mixed in the oil residue is squeezed out and passes through the filter holes of the filter cartridge 110 and falls into the lower end of the interior of the processing box 101. At the same time, the pressing plate 118 can be rotated and adjusted by adjusting the motor 116, and the vertical position of the pressing plate 118 can be adjusted by the first telescopic push rod 115, so that the pressing plate 118 can filter the mixture of oil residue and oil in different areas of the filter cartridge 110 in turn, thereby achieving sufficient filter pressing of the mixture of oil residue and oil in the filter cartridge 110, so that the oil mixed in the oil residue can be fully squeezed out, thereby achieving sufficient filtering of the oil.

[0045] After that, the box cover 119 can be removed again, so that the first hand-tightening bolt 307 is separated from the first threaded connection hole, and the connection between the connecting groove 305 and the connecting slide 306 is released. Then, the filter cartridge 110 can be taken out of the mounting frame 109, and then the filter cartridge 110 can be taken out of the processing box 101. After that, the oil residue remaining in the filter cartridge 110 can be cleaned.

[0046] As for the oil residue adhering to the pressing plate 118 , the motor 116 can be adjusted to rotate the pressing plate 118 , so that the adhering oil residue falls off from the pressing plate 118 through centrifugal action and falls into the filter cartridge 110 .

[0047] According to another embodiment of the present invention, Figure 2 、 Figure 3 and Figure 5As shown, the fixed frame 107 is further vertically provided with a plurality of second telescopic push rods 303, and the output shafts of the plurality of second telescopic push rods 303 are commonly provided with a support plate 304 for supporting the mounting frame 109. During the process of filtering the mixture of oil residue and oil in the filter cartridge 110, the vibration motor 111 can be first suspended, and then the output shafts of the plurality of second telescopic push rods 303 are extended to a certain length so that the support plate 304 is supported on the bottom of the mounting frame 109, so that the mounting frame 109 and the filter cartridge 110 are maintained at a corresponding height. After that, the mixture of oil residue and oil in the filter cartridge 110 can be subjected to pressure filtration. This avoids excessive downward displacement of the mounting frame 109 and the filter cartridge 110 due to lack of support during the pressure filtration process, thereby avoiding affecting the effect and efficiency of the pressure filtration and preventing pressure damage to the plurality of springs 108.

[0048] When the vibration motor 111 stops working, the output shafts of the multiple telescopic push rods can be synchronously extended to a certain length, so that the support plate 304 is close to or in contact with the bottom of the mounting frame 109, and the mounting frame 109 is assisted in vibration prevention, so that the mounting frame 109 stops vibrating more quickly, allowing the user to easily remove the filter cartridge 110 from the mounting frame 109.

[0049] According to another embodiment of the present invention, Figure 2 、 Figure 3 and Figure 5 As shown, the front end of the filter cartridge 110 is also provided with a handle 308. When the box cover 119 is opened, the filter cartridge 110 can be easily placed in or taken out of the processing box 101 by the handle 308, and the feed barrel can also be easily moved, so that the user can easily clean the collected oil residue.

[0050] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
