Description

Technical Field

[0001] The utility model relates to the technical field of plant extraction, in particular to a plant extract filtering device. Background Art

[0002] Plants are rich in a variety of nutrients and active ingredients, which can be widely used in the pharmaceutical industry, food industry, health industry and beauty industry, etc. Therefore, it is necessary to extract and concentrate one or more active ingredients in the plants through physical or chemical extraction and separation processes without changing the properties of the active ingredients. When extracting medicinal plants, the plants are generally mixed with solvents by soaking, heating or boiling, and the required substances are extracted by the principle of like dissolves like. After the extraction, the extract needs to be filtered. The purpose of filtration is to remove impurities in the plant extract to facilitate packaging, transportation, storage, processing and use.

[0003] The existing patent (publication number: CN215195815U) discloses a plant extract filtering device, including a support plate 1, a filter barrel, a filter basket and a hydraulic rod, wherein a filter basket is installed in the filter barrel through a fixing member 1, a filter bag is installed in the filter basket through a fixing member 2, and extrusion plates are provided on both sides of the filter bag, a connecting rod is installed on the extrusion plate, and a hydraulic rod is installed on the connecting rod. The utility model provides extrusion plates on both sides of the filter bag, so that the filtrate to be filtered enters the filter bag in the filter basket along the feed port, and when a certain amount of filter residue is accumulated in the gauze, part of the filtrate entering later will accumulate in the residue, causing a waste of resources. At this time, the hydraulic rods installed on the support plates on both sides drive the extrusion plates to compress inward, thereby squeezing the residue in the gauze, and squeezing the extract retained inside out of the filter bag, thereby reducing the consumption of the filtration process and improving the economic benefits of the device.

[0004] When the above patented technology is in use, the hydraulic rod drives the squeezing plate to compress inward, thereby squeezing the residue in the mesh and squeezing the extract retained inside out of the filter bag. However, in actual use, the hydraulic rod drives the squeezing plate to squeeze from both sides. During the squeezing, the plant residue in the filter bag is displaced to the upper and lower sides by the squeezing force. Since the overall area of ​​the squeezing plate is limited and cannot be moved, the plant residue at both ends of the filter bag, especially the upper end, cannot be squeezed by the squeezing force of the squeezing plate, resulting in the inability to squeeze out the residual extract, resulting in a certain degree of waste of the extract. Therefore, a plant extract filtering device is proposed. Utility Model Content

The output ends of the two electric push rods 8 are fixedly connected with side U-shaped frames 9, and pressure rollers 10 are rotatably connected between the outer surfaces of the front and rear sides of the two side U-shaped frames 9. Specifically, the electric push rods 8 drive the side U-shaped frames 9 to clamp the filter bag 4, and the motor 6 drives the threaded rod 5 connected to its output end to rotate. When the threaded rod 5 rotates, it drives the threaded plate 7 to move, and drives the pressure rollers 10 to move, so that the pressure rollers 10 squeeze the filter bag 4 from top to bottom, and squeeze the plant residues remaining inside the filter bag 4 in all directions, so that there is no extrusion dead angle, so that the extract can be completely discharged, avoiding the waste of the extract.

[0027] In this embodiment, the top outer surface of the connecting plate 2 is located around the supporting sleeve 3 and is fixedly connected with four positioning rods 19 arranged in a circular array. Four positioning holes 20 are opened in a circular array at the bag opening of the filter bag 4. The insides of the four positioning holes 20 are fixedly connected with connecting rings. Specifically, the bag opening of the filter bag 4 is put on the supporting sleeve 3, and the positioning holes 20 are put on the positioning rods 19 to position the filter bag 4. The connecting ring is provided to prevent the positioning holes 20 of the filter bag 4 from being torn.

[0028] In this embodiment, the top outer surface of the filter box 1 is fixedly connected to a gantry 11, and a hydraulic cylinder 12 is fixedly installed on the top outer surface of the gantry 11. The mounting end of the hydraulic cylinder 12 is fixedly connected to the top outer surface of the gantry 11, and the output end of the hydraulic cylinder 12 is fixedly connected to a fixed disk. The bottom outer surface of the fixed disk is fixedly connected to a clamping sleeve 13, and the bottom outer surface of the clamping sleeve 13 is provided with four insertion holes 21 corresponding to the positioning rod 19. Specifically, the hydraulic cylinder 12 drives the clamping sleeve 13 to align the insertion holes 21 with the positioning rod 19 until the clamping sleeve 13 fixes the bag mouth of the filter bag 4 on the connecting plate 2, thereby fixing the filter bag 4 to prevent the filter bag 4 from detaching from the support sleeve 3 when the filter bag 4 is squeezed.

[0029] In this embodiment, a support plate 14 is fixedly connected to the middle end of the inner surface of the filter box 1, and the two threaded plates 7 are rotated to penetrate the support plate 14. The center of the support plate 14 is a steel mesh. Specifically, the bottom of the filter bag 4 is supported by the support plate 14, and the extract is discharged from the filter bag 4 and passes through the support plate 14 through the steel mesh.

[0030] In this embodiment, the bottom outer surfaces of the two threaded rods 5 are fixedly connected to the transmission wheels 17, and a belt 18 is wound between the two transmission wheels 17. Specifically, the motor 6 drives the threaded rod 5 connected to its output end to rotate, driving the transmission wheel 17 thereon to rotate, and under the action of the belt 18, drives the other threaded rod 5 to rotate, so that the two threaded rods 5 rotate at the same time.

[0031] In this embodiment, the inner surface of the filter box 1 is located below the support plate 14 and is fixedly connected to a support frame 15. A filter plate 16 is movably inserted inside the support frame 15. The filter plate 16 movably penetrates the front outer surface of the filter box 1. Specifically, after the extract is discharged from the filter bag 4, it is filtered again through the filter plate 16, thereby performing double filtration, which improves the filtering effect of the extract. When the filter plate 16 needs to be cleaned, the filter plate 16 can be directly pulled out for cleaning.

[0032] In this embodiment, an inverted V-shaped guide plate 22 is fixedly connected to the bottom outer surface of the support plate 14, and the inverted V-shaped guide plate 22 is located above the belt 18. Specifically, the inverted V-shaped guide plate 22 is provided to guide the extraction liquid to prevent the extraction liquid from dripping onto the belt 18 and affecting the transmission capacity of the belt 18.

[0033] In this embodiment, four sliding rods are fixedly connected between the relative outer surfaces of the connecting plate 2 and the supporting plate 14. The four sliding rods are respectively located on the front and rear sides of the two threaded rods 5. The two threaded plates 7 are respectively mounted on the outer surfaces of the four sliding rods. Specifically, during the rotation of the threaded rods 5, the threaded plates 7 are driven to move, so that the threaded plates 7 slide on the outer surfaces of the sliding rods, thereby preventing the threaded plates 7 from rotating with the rotation of the threaded rods 5.

[0034] Working principle: When the utility model is in use, the plant extract to be filtered is poured into the filter bag 4 for filtering. As the filtering work proceeds, a certain amount of plant residues will remain in the filter bag 4. At this time, the motor 6 is turned on, and the motor 6 drives the threaded rod 5 connected to its output end to rotate, driving the transmission wheel 17 thereon to rotate, and driving the other threaded rod 5 to rotate under the action of the belt 18, so that the two threaded rods 5 rotate at the same time. When the threaded rod 5 rotates, it drives the threaded plate 7 thereon to move, so that the threaded plate 7 is located at the top, and then the electric push rod 8 works, and the electric push rod 8 drives the side U-shaped frame 9 to make the pressure roller 10 and the filter bag 4 The filter bag 4 is in contact with the filter bag 4, and the filter bag 4 is clamped under the action of the two pressing rollers 10. The plant liquid in the plant residues remaining in the filter bag 4 is squeezed out under the squeezing force of the two pressing rollers 10. As the motor 6 works, the threaded plate 7 is driven to move, so that the pressing roller 10 moves from top to bottom to omnidirectionally squeeze the plant residues remaining inside the filter bag 4, so that there is no squeezing dead angle, so that the extract can be completely discharged, avoiding the waste of the extract. After the extract is discharged from the filter bag 4, it is filtered again through the filter plate 16, thereby performing double filtration, which improves the filtering effect of the extract, and finally falls into the bottom of the filter box 1 for collection.

[0035] When fixing the filter bag 4, first put the bag mouth of the filter bag 4 on the support sleeve 3, and make the positioning hole 20 sleeve on the positioning rod 19 to position the filter bag 4. When it is necessary to squeeze the filter bag 4 from top to bottom, the hydraulic cylinder 12 is operated, and the hydraulic cylinder 12 drives the clamping sleeve 13 to align the insertion hole 21 with the positioning rod 19 until the clamping sleeve 13 fixes the bag mouth of the filter bag 4 on the connecting plate 2 to fix the filter bag 4 to prevent the filter bag 4 from detaching from the support sleeve 3 when squeezing the filter bag 4. When the filter bag 4 needs to be replaced, it is only necessary to retract the hydraulic cylinder 12 and remove the filter bag 4 from the positioning rod 19 to clean and replace the filter bag 4.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
