Description

Technical Field

[0001] The invention belongs to the technical field of squeezing and filtering, in particular to a rapeseed oil filter press. Background Art

[0002] Among the current edible oils, there are peanut oil, sunflower oil and rapeseed oil. The absorption rate of rapeseed oil by the human body is very high. Rapeseed oil has certain effects of softening blood vessels and delaying aging. Since the raw material for oil extraction is plant seeds, it generally contains certain seed phospholipids. Rapeseed oil has less cholesterol, so people who control their cholesterol intake can eat it with confidence. In the manufacturing process of rapeseed oil, it needs to be pressed and filtered.

[0003] A patent with publication number CN219028623U discloses a rapeseed oil press. By laying a filter membrane, the oil outlet part at the bottom can be blocked and a filtering effect can be provided. The filter membrane can be directly replaced after use, and there is no need to clean the blocked position, which reduces the pressure of subsequent cleaning.

[0004] In the above-mentioned prior art, the rapeseed oil needs to be filtered after being squeezed out, and the squeezed rapeseed oil needs to be transferred to a filtering device for filtering, which is time-consuming and labor-intensive. The filtering device is set next to the press, which occupies a large space. The above-mentioned scheme only filters the rapeseed oil once, and the filtering effect is limited. Although the traditional multi-layer filter structure can improve the filtering effect, the rapeseed oil needs to pass through multiple layers of filter screens during filtration, and the multi-layer filter screens are more troublesome to clean and inconvenient to use. At the same time, the filtered particulate impurities also contain a small amount of rapeseed oil, and the impurities need to be removed and then squeezed a second time, which is more cumbersome.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] Embodiment 1: Figure 1-4As shown, a rapeseed oil filter press according to an embodiment of the present invention comprises a first cylinder 1, a first ring 11 is fixedly connected to the upper end of the first cylinder 1, a hollow cylinder 12 is arranged in the middle of the first cylinder 1, the upper end of the hollow cylinder 12 is fixedly connected to the first ring 11, a first cylindrical block 121 is fixedly connected to the lower end of the hollow cylinder 12, a second ring 13 is fixedly connected to the outer side of the lower end of the first cylinder 1, a third ring 132 is fixedly connected to the four corners of the lower end of the second ring 13 through a first arc block 131, a fifth cylinder 133 is fixedly connected to the upper end of the third ring 132, a first filter assembly is arranged at the lower end of the hollow cylinder 12, and the first filter assembly comprises a first cylindrical block 121 fixedly connected to the outer side of the first cylindrical block 121 An annular hollow plate 14, the outer side of which is fixedly connected to the fifth cylinder 133, a stainless steel filter screen 141 is installed on the upper end of the annular hollow plate 14, the inner upper end of the annular hollow plate 14 is an inclined surface, the lower end of the third ring 132 is fixedly connected to the third cylinder 2 through the second arc block 17, the lower end of the third cylinder 2 is fixedly connected to the bottom plate 4, one side of the upper end is fixedly connected to a cylindrical rod 115, the upper end of the cylindrical rod 115 is rotatably connected to a cover plate 111, the middle part of the cover plate 111 is slidably penetrated by an extrusion plate 114, the upper end of the extrusion plate 114 is fixedly connected to the output end of a hydraulic rod 113, and the hydraulic rod 113 is fixedly connected to the cover plate 111 through a U-shaped support block 112.

[0030] Specifically, when processing rapeseed oil, it is necessary to squeeze the rapeseed to squeeze out the rapeseed oil. Since the rapeseed particles are small, the rapeseed may contain impurities, and the squeezed rapeseed oil needs to be filtered. The existing machine first squeezes the rapeseed, and then transfers the squeezed rapeseed oil to a filtering machine for filtration. During the transfer process, more impurities may fall into the rapeseed oil, and the rapeseed oil needs to be transferred, which is relatively laborious. When using the present invention, the rapeseed is poured into the hollow cylinder 12, and then the cover plate 111 is driven to rotate to the upper end of the first ring 11, and then the hydraulic rod 113 is driven to extend, driving the squeezing plate 114 to extend into the hollow cylinder 12, and the rapeseed inside the hollow cylinder 12 is squeezed. The squeezed rapeseed oil is filtered by the hollow cylinder 12. Some small holes flow out and flow to the upper end of the stainless steel filter screen 141, and the stainless steel filter screen 141 filters the squeezed rapeseed oil. The filtered rapeseed oil passes through the annular hollow plate 14 and flows to the lower end for collection. The annular hollow plate 14 is set to have an upwardly inclined shape inside so that the stainless steel filter screen 141 is close to the annular hollow plate 14. When the rapeseed oil passes through the stainless steel filter screen 141 for filtering, the filtered impurities slide to the lower end of the annular hollow plate 14 through the beveled edge provided inside the annular hollow plate 14, so that impurities will not accumulate on one side of the bevel of the stainless steel filter screen 141, thereby preventing the stainless steel filter screen 141 from being blocked, thereby solving the problem of the need to transfer the squeezed rapeseed oil for filtration, which is time-consuming and labor-intensive, and preventing the stainless steel filter screen 141 from being blocked during filtration.

[0031] like Figure 4As shown, in this embodiment, the lower end of the second circular ring 13 is rotatably connected to the fifth circular ring 16, and the first rectangular bars 161 are fixedly connected to both sides of the lower end of the fifth circular ring 16, the ends of the first rectangular bar 161 are fixedly connected to the second rectangular bars 162, and the ends of the second rectangular bar 162 are fixedly connected to the arc scraper 163, and the arc scraper 163 is attached to one side of the upper inclined surface of the stainless steel filter 141.

[0032] Specifically, when there are many impurities, the fifth ring 16 is driven to drive the first rectangular bar 161 to rotate, and the first rectangular bar 161 drives the arc scraper 163 to rotate through the second rectangular bar 162, so that the arc scraper 163 rotates along the inclined side of the stainless steel filter screen 141, which can scrape off the impurities remaining on the stainless steel filter screen 141, and further prevent the obstruction of the inclined side of the stainless steel filter screen 141.

[0033] like Figure 4 As shown, in this embodiment, the upper end of the third ring 132 is provided with an extrusion assembly, and the extrusion assembly includes a fourth ring 15 rotatably connected to the upper end of the third ring 132, and telescopic rods 151 are respectively fixedly connected on both sides of the upper end of the fourth ring 15, and a first spring 152 is sleeved on the outer side of the telescopic rod 151. A U-shaped block 154 is fixedly connected to the upper end of the telescopic rod 151, and a roller 155 is rotatably connected to one side of the U-shaped block 154, and the roller 155 is fitted on the upper end of the stainless steel filter screen 141.

[0034] Specifically, the impurities filtered out from above the stainless steel filter 141 also contain a small amount of rapeseed oil, which can be further extracted. When using the present invention, the fourth ring 15 is driven to rotate to drive the telescopic rod 151 to rotate, and the telescopic rod 151 drives the roller 155 to rotate along the upper end of the stainless steel filter 141 through the U-shaped block 154. A first spring 152 is provided to drive the roller 155 to be close to the upper end of the stainless steel filter 141. The roller 155 rotates and squeezes the impurities on the upper end of the stainless steel filter 141 at the same time. The rapeseed oil with impurities is squeezed out by driving the roller 155, thereby saving resources.

[0035] like Figure 6 As shown, in this embodiment, a fourth cylinder 21 is provided in the middle of the third cylinder 2 , and a first funnel 3 is fixedly connected in the middle of the fourth cylinder 21 .

[0036] Specifically, the squeezed rapeseed oil falls into the third cylinder 2 and is collected uniformly through the first funnel 3.

[0037] like Figure 3 , 5 As shown in FIG. 6 , a clamping assembly is provided on the opposite side of the fourth cylinder 21 and the third ring 132 in this embodiment. The clamping assembly includes a sixth ring 22 fixedly connected to one side of the fourth cylinder 21 , and filter paper 25 is installed in the middle of the two sixth rings 22 .

[0038] Specifically, the stainless steel filter 141 can perform preliminary filtration of impurities in the rapeseed oil, and then the rapeseed oil needs to be finely filtered to further reduce impurities. When using the present invention, filter paper 25 is installed in the middle of the two sixth rings 22, and the rapeseed oil falls into the upper end of the filter paper 25 for filtration. The rapeseed oil filtered by the stainless steel filter 141 directly falls to the upper end of the filter paper 25 for filtration, which can perform secondary filtration while reducing the volume of the equipment.

[0039] like Figure 3 , 5 As shown, in this embodiment, the upper end of the sixth circular ring 22 located at the upper end is fixedly connected to the seventh circular ring 26, and the third rectangular blocks 261 are fixedly connected on both sides of the seventh circular ring 26. The two sides of the third circular ring 132 are fixedly connected to the first rectangular blocks 1321, and the first rectangular blocks 1321 are connected to the third rectangular blocks 261 by bolts.

[0040] Specifically, the filter paper 25 is a disposable item and needs to be replaced after use. When using the present invention, the driving bolt is rotated to drive the seventh ring 26 to move upward through the third rectangular block 261, and the seventh ring 26 drives the sixth ring 22 above to move upward, then the filter paper 25 is removed and replaced with a new filter paper 25, and then the bolt is driven to rotate again to drive the sixth ring 22 above to move downward through the seventh ring 26 until the filter paper 25 is clamped, and the replacement is completed.

[0041] like Figure 3 As shown, in this embodiment, the lower end of the first cylindrical block 121 is rotatably connected to a cylindrical bar 122 , and the end of the cylindrical bar 122 is fixedly connected to a scraper 123 .

[0042] Specifically, when impurities are attached to the top of the filter paper 25, the speed of the filter paper 25 will slow down. When using the present invention, the cylindrical bar 122 is driven to drive the scraper 123 to rotate, and the scraper 123 can scrape the impurities attached to the upper end of the filter paper 25 to prevent the filter paper 25 from being blocked.

[0043] like Figure 3 As shown, in this embodiment, an air pump 5 is installed on one side of the upper end of the bottom plate 4, and the air pump 5 passes through one side of the third cylinder 2 and the fourth cylinder 21.

[0044] Specifically, by starting the air pump 5 to extract the air in the fourth cylinder 21 and the air at the lower end of the filter paper 25 , the filtering efficiency of the filter paper 25 can be increased.

[0045] like Figure 5As shown, the clamping assembly described in this embodiment also includes rectangular grooves 221 respectively provided on the four sides of one side of the sixth circular ring 22, and one side inside the rectangular grooves 221 is fixedly connected to the rectangular slider 224 through a second spring 223, and first arc strips 23 are respectively provided at both ends of one side of the sixth circular ring 22, and a second arc strip 24 is slidably connected between two adjacent first arc strips 23, and the first arc strip 23 and the second arc strip 24 are respectively fixedly connected to the relative rectangular sliders 224.

[0046] Specifically, the first arc strip 23 and the second arc strip 24 are flexible deformable materials, and the filter paper 25 is clamped by the first arc strip 23 and the second arc strip 24. When the filter paper 25 is blocked and the air permeability becomes poor, the air pump 5 continues to inhale air, which may cause the filter paper 25 to fall off. When using the present invention, when the filter paper 25 has been used for a long time and the air permeability becomes poor, the middle part of the filter paper 25 is concave downward, and at the same time, the two ends of the second arc strip 24 are driven to slide toward the inside of the first arc strip 23 at the same time, and the rectangular slider 224 is driven to slide toward the middle of the sixth ring 22, and the second spring 223 is stretched at the same time. When the middle part of the filter paper 25 is concave downward, the first arc strip 23 and the second arc strip 24 drive the edge of the filter paper 25 to buffer toward the middle to prevent the filter paper 25 from falling off.

[0047] Embodiment 2: Figure 5-6 As shown, compared with Example 1, another implementation of the present invention is: a circular hole 222 is respectively provided on one side of the rectangular groove 221, and the rectangular slider 224 is respectively fixed with a rope 31, and the rope 31 passes through the circular hole 222, and the rope 31 is fixed with a second funnel 32 at one end away from the rectangular slider 224, and a hollow circular plate 33 is fixed to the middle of the second funnel 32, and a conical block 34 is fixed to the upper end of the hollow circular plate 33, and the conical block 34 is located at the lower end of the first funnel 3.

[0048] Specifically, when the filter paper 25 is blocked and drives the rectangular slider 224 to slide toward the middle of the sixth ring 22 at the same time, the rectangular slider 224 drives the second funnel 32 to move upward through the rope 31, and the second funnel 32 drives the hollow circular plate 33 and the conical block 34 to move upward. When the air permeability of the filter paper 25 deteriorates, it drives the conical block 34 to move upward and slide to the inside of the lower end of the first funnel 3, shrinking the hole at the lower end of the first funnel 3, thereby reducing the suction force on the filter paper 25. The distance between the conical block 34 and the first funnel 3 can be automatically adjusted according to the air permeability of the filter paper 25, so as to control the air intake port at the lower end of the first funnel 3 to become smaller, adjust the suction force of the filter paper 25, and further prevent the filter paper 25 from falling off.

[0049] Working principle: during processing, rapeseed is poured into the hollow cylinder 12, and then the cover plate 111 is driven to rotate to the upper end of the first ring 11, and then the hydraulic rod 113 is driven to extend, driving the extrusion plate 114 to extend into the hollow cylinder 12, and the rapeseed inside the hollow cylinder 12 is squeezed, and the squeezed rapeseed oil flows out from the small holes provided around the hollow cylinder 12, and flows to the upper end of the stainless steel filter 141, and the stainless steel filter 141 filters the squeezed rapeseed oil, and at the same time, the fifth ring 16 is driven to drive the first rectangular bar 161 to rotate, and the first rectangular bar 161 drives the arc scraper 163 to rotate through the second rectangular bar 162, so that the arc scraper 163 rotates along one side of the inclined surface of the stainless steel filter 141, so that the impurities remaining on the stainless steel filter 141 can be scraped off, and the obstruction of the oblique side of the stainless steel filter 141 can be further prevented;

[0050] Then, the fourth ring 15 is driven to rotate to drive the telescopic rod 151 to rotate, and the telescopic rod 151 drives the roller 155 to rotate along the upper end of the stainless steel filter 141 through the U-shaped block 154. A first spring 152 is provided to drive the roller 155 to be close to the upper end of the stainless steel filter 141. The roller 155 rotates and squeezes the impurities on the upper end of the stainless steel filter 141. The rapeseed oil with impurities is squeezed out by driving the roller 155, and the squeezed rapeseed oil falls into the third cylinder 2 and is uniformly collected by the first funnel 3;

[0051] Then the rapeseed oil falls into the upper end of the filter paper 25 for filtration, and the rapeseed oil filtered by the stainless steel filter screen 141 falls directly onto the upper end of the filter paper 25 for filtration, and performs secondary filtration. When impurities are attached to the upper end of the filter paper 25, the speed of the filter paper 25 will slow down. When the present invention is used, the cylindrical bar 122 is driven to drive the scraper 123 to rotate, and the scraper 123 can scrape the impurities attached to the upper end of the filter paper 25 to prevent the filter paper 25 from being blocked;

[0052] By starting the air pump 5 to extract the air in the fourth cylinder 21 and the air at the lower end of the filter paper 25, the filtering efficiency of the filter paper 25 can be accelerated. When the air permeability of the filter paper 25 deteriorates after a long period of use, the middle of the filter paper 25 sags downward, and at the same time drives both ends of the second arc strip 24 to slide toward the inside of the first arc strip 23, and at the same time drives the rectangular slider 224 to slide toward the middle of the sixth ring 22, and at the same time stretches the second spring 223. When the middle of the filter paper 25 sags downward, the first arc strip 23 and the second arc strip 24 drive the edge of the filter paper 25 to buffer toward the middle to prevent the filter paper 25 from falling off. At the same time, the rectangular slider 224 drives the second funnel 32 to move upward through the rope 31, and the second funnel 32 drives the hollow circular plate 33 and the conical block 34 to move upward. When the air permeability of the filter paper 25 deteriorates, the conical block 34 is driven to move upward and slide to the inside of the lower end of the first funnel 3, thereby reducing the hole at the lower end of the first funnel 3, thereby reducing the suction force on the filter paper 25. The distance between the conical block 34 and the first funnel 3 can be automatically adjusted according to the air permeability of the filter paper 25, thereby controlling the air intake port at the lower end of the first funnel 3 to become smaller, adjusting the suction force of the filter paper 25, and further preventing the filter paper 25 from falling off.
