Description

Technical Field

[0001] The utility model relates to the technical field related to plant fermentation filtration, and in particular to a fermentation liquid filtration device. Background Art

[0002] Vitamin C mainly comes from fresh fruits and vegetables. It has two isomers, L-type and D-type. Only the L-type has physiological functions, and both the reduced and oxidized types have physiological activities. Vitamin C is a colorless and odorless flaky crystal that is easily soluble in water but insoluble in organic solvents. Oxidase is generally found in high levels in vegetables, so vegetables are lost to varying degrees during storage. However, the bioflavonoids contained in some fruits can protect its stability. The fermentation of vitamin C refers to the process of converting raw materials into vitamins through fermentation and then separating and purifying them from the fermentation broth through biological separation technology to obtain vitamin C products that meet the requirements.

[0003] The utility model patent "A fermentation liquid filtering device for health food production" with the publication number of CN218900996U in my country discloses a fermentation liquid filtering device for health food production. The fermentation liquid enters the box body through the feed pipe, and the motor is started to drive the rotating shaft to rotate. The rotating shaft drives the stirring rod to rotate to stir the fermentation liquid in the box body, so that the fermentation liquid is uniform and not easy to precipitate, and some impurities can be separated from the filter screen during rotation. When the first filter plate is blocked after long-term operation, the motor is first turned off to make the impurities flow through the first filter plate. The first filter plate is taken out by the handle for cleaning, and the slide plate is moved to the top opening of the box body to seal the box opening. At this time, the second filter plate is responsible for filtering. After the first filter plate is cleaned, the slide plate is moved again to be put in through the top opening of the box body. At this time, the second filter plate is taken out by the handle. When the second filter plate is taken out, one side of the bottom end slides with one side of the first filter plate, and the impurities between the first filter plate and the second filter plate can be taken out. This device can clean the filter screen without stopping during the fermentation liquid filtration, thereby improving the work efficiency.

[0004] However, the above patent still has the following shortcomings: although the alternating use of two filter plates facilitates cleaning to solve the problem of filter clogging, the residue in the fermentation liquid presses against the surface of the filter plate due to the pressure difference during filtration. However, when the filter plate is taken out upward, the residue adsorbed on the filter plate is easy to fall into the fermentation liquid again, and the residue in the box is not easy to clean, so it is necessary to design a fermentation liquid filtering device.

[0028] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0029] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0030] like Figure 1-6 As shown, a fermentation liquid filtering device comprises: a main support, a horizontal support ring 1 fixedly mounted on the top of the main support, a filter bag 2, an annular mounting mechanism detachably mounted on the open end of the filter bag 2 and capable of being placed on the support ring 1, a bottom plate 3 assembled in the middle of the main support and arranged coaxially with the support ring 1, an annular liquid collecting member 4 whose inner edge is fixedly fitted to the bottom plate 3, and an extrusion unit for extruding the outer wall of the filter bag 2;

[0031] The extrusion unit includes a motor 5 mounted on the chassis 3 through a mounting frame, a rotating shaft 6 fixedly connected to the output shaft of the motor 5 and coaxially arranged with the chassis 3, a connecting disk 7 coaxially fixedly mounted on the rotating shaft 6, a plurality of extrusion rods 8 evenly distributed along the circumferential direction of the connecting disk 7 and hinged to the connecting disk 7 at the lower ends, and a swing transmission mechanism mounted on the mounting frame and connected to the plurality of extrusion rods 8, and used for driving the plurality of extrusion rods 8 to swing back and forth around corresponding hinges when the connecting disk 7 rotates.

[0032] The fermentation liquid is transported to the filter bag 2, and the residue contained therein will be intercepted in the filter bag 2, and the liquid will pass through the filter bag 2 and flow into the annular liquid collecting member 4. When the filter bag 2 is filled with the fermentation liquid, the outer wall of the filter bag 2 will contact the extrusion rod 8, and the motor 5 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives a plurality of extrusion rods 8 to rotate around the axis of the rotating shaft 6 through the connecting plate 7. The extrusion rod 8 rotates in contact with the outer wall of the filter bag 2, so that the residue in the filter bag 2 is separated from the inner wall of the filter bag 2. Because a swing transmission mechanism is provided, the extrusion rod 8 will reciprocate around the hinge while rotating around the rotating shaft 6. The purpose of rotating the extrusion rod 8 around the rotating shaft 6 and around the hinge is to keep the lower half of the filter bag 2 in motion, thereby preventing the internal residue from clogging the filter bag 2. Because the lower half of the filter bag 2 is in motion, it is beneficial for the residue adhering to the inner wall of the filter bag 2 to separate from the inner wall of the filter bag 2 and settle to the bottom of the filter bag 2.

[0033] When cleaning the residue, the filter bag 2 and the annular mounting mechanism are removed, and the filter bag 2 is turned over, so that all the residue inside the filter bag 2 can be poured out, and the cleaning is convenient and quick.

[0034] When the filter bag 2 needs to be replaced, the annular mounting mechanism is removed from the filter bag 2 and assembled onto a new filter bag 2 .

[0035] The top of the rotating shaft 6 is coaxially connected to a support plate 9 located above the connecting plate 7 and used for supporting the bottom of the filter bag 2 through a bearing.

[0036] The support plate 9 is used to hold the top of the filter bag 2. When the motor 5 drives the rotating shaft 6 to rotate, because the support plate 9 is connected to the rotating shaft 6 through the bearing, the fermentation liquid in the filter bag 2 will exert pressure on the support plate 9. Under the action of the filter bag 2 and the pressure, the rotation of the rotating shaft 6 will not drive the support plate 9 to rotate.

[0037] The outer diameter of the support plate 9 is larger than the outer diameter of the connecting plate 7. The lower end of the extrusion rod 8 is fixedly connected with a bending piece 10. The bending part of the bending piece 10 is assembled on the connecting plate 7 through a hinge seat. The end of the bending piece 10 away from the extrusion rod 8 is connected to the swing transmission mechanism.

[0038] The swing transmission mechanism drives the extrusion rod 8 to rotate by driving the bending member 10 to reciprocate around the hinge seat.

[0039] The swing transmission mechanism includes an annular guide rail 11 fixedly mounted on the mounting frame and coaxially arranged with the connecting plate 7, the annular guide rail 11 is provided with a plurality of curved portions 12 spaced apart in the circumferential direction and protruding toward the rotating shaft 6, each bending member 10 is hingedly connected to a connecting rod 13 at one end away from the extrusion rod 8, and the connecting rod 13 is hingedly connected to a sliding member 14 slidably assembled on the annular guide rail 11 at one end away from the bending member 10.

[0040] When the motor 5 drives the connecting plate 7 to rotate via the rotating shaft 6 , each extrusion rod 8 will drive the axis of the rotating shaft 6 to rotate, and at the same time, the connecting plate 7 will also drive the sliding member 14 to slide on the annular guide rail via the connecting rod 13 .

[0041] When the sliding member 14 slides into the bending portion 12 from the annular guide rail 11, the sliding member 14 moves close to the axis of the rotating shaft 6, and the sliding member 14 pulls the bending member 10 to rotate through the connecting rod 13, and the bending member 10 drives the upper end of the extrusion rod 8 to rotate away from the axis of the rotating shaft 6; when the sliding member 14 slides out of the bending portion 12, the sliding member 14 moves away from the axis of the rotating shaft 6, and the sliding member 14 pushes the bending member 10 to rotate in the opposite direction through the connecting rod 13, thereby driving the upper end of the extrusion rod 8 to move close to the axis of the rotating shaft 6.

[0042] The upper end of the extrusion rod 8 is bent away from the axis of the chassis 3 to form a rounded portion 15. The cross-section of the extrusion rod 8 is circular, which can reduce the friction force of the extrusion rod 8 on the filter bag 2 when the extrusion rod 8 contacts the filter bag 2, avoid the extrusion rod 8 directly scratching the filter bag 2, and increase the service life of the filter bag 2.

[0043] An inclined guide plate 16 is fixedly attached to the extrusion rod 8 , and the inclined upper end of the guide plate 16 is located below the support plate 9 . A U-shaped flow limiting portion protrudes upward from the edge of the guide plate 16 , and the notch of the flow limiting portion is located at the inclined lower end of the guide plate 16 .

[0044] Because the extrusion rod 8 is in contact with the outer wall of the filter bag 2, part of the liquid will flow downward along the extrusion rod 8, and the guide plate 16 will guide the liquid to flow away from the rotating shaft 6. The function of the flow limiting part is to allow the liquid to flow out only from the inclined lower end of the guide plate 16.

[0045] A first tubular shell 17 is fixedly provided on the edge of the support plate 9 , the extrusion rod 8 passes through the first tubular shell 17 , and a limiting sleeve portion protrudes upward from the base plate 3 and is inserted into the inner side of the first tubular shell 17 .

[0046] The first tubular shell 17 and the limiting sleeve portion function to prevent the filtered liquid from entering the vicinity of the motor 5 . The liquid splashes onto the first tubular shell 17 and the limiting sleeve portion and also flows into the annular liquid collecting member 4 .

[0047] The main bracket is fixedly equipped with a second tubular housing 18 which is sleeved on the outside of the filter bag 2 and located just above the annular liquid collecting member 4 .

[0048] The function of the second tubular shell 18 is to intercept the liquid filtered from the filter bag 2 so that the liquid sprayed outward onto the inner wall of the second tubular shell 18 will flow downward into the annular liquid collecting member 4 .

[0049] The annular mounting mechanism includes an upper ring plate 19 , a lower ring plate 20 connected to the upper ring plate 19 by a plurality of bolts, and a middle ring plate 21 located between the upper ring plate 19 and the lower ring plate 20 , and the open end of the filter bag 2 can be sleeved on the middle ring plate 21 .

[0050] When the filter bag 2 needs to be replaced, the bolts are loosened and removed, and the upper ring piece 19, the middle ring piece 21 and the lower ring piece 20 can be separated. Then the open edge of the new filter bag 2 is put on the middle ring piece 21, and then the upper ring piece 19 and the lower ring piece 20 clamp the middle ring piece 21 from both sides, and the upper ring piece 19 and the lower ring piece 20 are fixed together by bolts.

[0051] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0052] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0053] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
