Description

Technical Field

[0001] The present application relates to the technical field of food processing and filtration, and specifically discloses a filtration device for food processing. Background Art

[0002] In the processing of wine and beverages, filtration technology is one of the essential processing steps. Filtering wine and beverages can effectively separate the solid and liquid, thereby obtaining clearer and purer wine and beverage products.

[0003] In the process of preliminary filtration of wine and beverages, including the filtration of raw materials and additional products, existing processing and filtration mechanisms usually use gauze or filter screens to filter impurities in wine and beverages.

[0004] However, during the initial filtration process, since a large amount of raw materials are mixed in the liquid in the form of clumps and piles, the raw materials will accumulate on the surface of the gauze or filter during filtration. The large amount of raw materials will not only cause blockage of the gauze or filter, but will also cause the gauze and filter to deform and break at the edges due to gravity, affecting the normal use of the filtration mechanism.

[0005] Therefore, in the prior art, during the filtering process of wine and beverages, it is necessary to regularly clean the accumulated and clumped raw materials on the gauze or filter screen, and during the cleaning process, the entire filtering equipment is in a shutdown state, resulting in a long processing time for the wine and beverage filtering process and low overall filtration efficiency.

[0006] Therefore, in view of this, the inventor provides a filtering device for food processing to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to solve the problem that in the traditional preliminary filtration process of wine and beverages, it is necessary to stop the machine regularly to clean the raw materials accumulated inside, resulting in a long processing time for the filtration process of the wine and beverage.

[0008] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides a filtering device for food processing, comprising a filtering tube, a power barrel fixedly connected to the top of the filtering tube, a slag collecting barrel fixedly connected to the bottom of the filtering tube, and a connecting water pipe coaxially fixedly connected to the filtering tube, wherein the top of the connecting water pipe is closed, and the bottom of the connecting water pipe extends out of the slag collecting barrel, and a slag discharge plate is detachably connected to the bottom of the slag collecting barrel;

[0009] The outer wall of the connecting water pipe located inside the filter pipe is circumferentially provided with a plurality of liquid inlet slots, and a plurality of isolation plate net structures are equidistantly arranged on the outer side of the connecting water pipe from both ends of the filter pipe inwardly, and the isolation plate net structures are, from top to bottom, a top fixed screen fixedly connected between the connecting water pipe and the inner cavity of the filter pipe, a middle movable screen rotatably connected between the connecting water pipe and the inner cavity of the filter pipe, and a bottom movable screen, a plurality of mutually parallel first net wires are equidistantly arranged in the top fixed screen, and a plurality of second net wires parallel to and corresponding to the first net wires are equidistantly arranged in the middle movable screen and the bottom movable screen;

[0010] A positioning structure for rotating and fixing the middle movable screen and the bottom movable screen is arranged on the filter tube.

[0011] Furthermore, it also includes a connecting shaft coaxially arranged in the connecting water pipe and a spiral water supply guide plate fixedly connected to the connecting shaft along the axial direction, and the outer wall of the spiral water supply guide plate is in contact with the inner wall of the connecting water pipe.

[0012] Furthermore, a continuous drainage spiral groove is provided in the spiral water supply guide plate, the end of the drainage spiral groove passes through the spiral water supply guide plate and extends to the bottom of the connecting water pipe, a plurality of filter holes connected to the drainage spiral groove are provided on the top surface of the spiral water supply guide plate, and a block for sealing the spiral water supply guide plate is detachably connected to the bottom of the connecting water pipe.

[0013] Furthermore, the connecting shaft is rotatably connected to the connecting water pipe, and a driving structure for driving the connecting shaft to rotate is provided on the top of the power barrel.

[0014] Furthermore, the driving structure includes a rotating shaft coaxially fixed to the connecting shaft and a driving motor fixed to the power barrel for driving the rotating shaft to rotate.

[0015] Furthermore, a plurality of stirring rods are fixedly connected circumferentially on the rotating shaft.

[0016] Furthermore, the isolation plate mesh structure is arranged outside the connecting water pipe between the two ends of the filter tube.

[0017] The principle and effect of this scheme are:

[0018] 1. Compared with the prior art, the present invention uses a filter tube, a power barrel and a slag collecting barrel to store the liquid to be filtered, and realizes multi-layer and multiple filtering through the isolation plate mesh structure installed in the filter tube. The filtered liquid is discharged through a connecting water pipe, and the filtered impurities are temporarily stored in the slag collecting barrel.

[0019] 2. Compared with the prior art, the present invention comprises a group of isolation plate mesh structures consisting of a top fixed mesh, a middle movable mesh and a bottom movable mesh. By rotating the middle movable mesh and the bottom movable mesh, an angle-stroke screen structure is formed between the middle movable mesh and the top fixed mesh. The aperture size of the screen structure can be changed by changing the size and spacing arrangement of the first mesh wire and the second mesh wire.

[0020] 3. Compared with the prior art, the present invention can rotate the middle movable screen and the bottom movable screen through the positioning structure, so that the second mesh wire inside it is offset from the first mesh wire at an angle to form mesh holes of different shapes and sizes. When the mesh holes formed by the three layers of mesh wires are smaller than the size of any raw material impurities, the filtering function of the raw material impurities can be completed; at the same time, the mesh hole spacing can be adjusted from top to bottom to form a gradual reduction, and has a trend of step-by-step reduction, and multi-layer and multiple step-by-step filtration can be achieved.

[0021] 4. Compared with the prior art, after a large amount of raw material impurities are stored on the installed isolation plate mesh structure, the present invention can also rotate the middle movable screen and the bottom movable screen in turn, driving the second mesh wires on the middle movable screen and the bottom movable screen to rotate, thereby expanding the size of the mesh formed by the first mesh wire and the two layers of second mesh wires below, so that the raw material impurities accumulated on the top enter the slag collecting barrel for temporary storage and then reset the three layers of mesh wires in turn, thereby realizing continuous filtration of the liquid without stopping the machine, solving the problem that in the traditional preliminary filtration process of wine and beverages, the machine needs to be shut down regularly to clean the raw materials accumulated inside, resulting in a long processing time for the filtration process of wine and beverages.

[0022] 5. Compared with the prior art, the present invention can achieve secondary fine filtration through the installed spiral water supply guide plate and the "sandwich" inside the spiral water supply guide plate, that is, the liquid discharge spiral groove, and can achieve rapid filtration through the liquid inlet slot opened on the connecting water pipe, thereby accelerating the liquid filtration speed.

[0031] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0032] The figure marks in the drawings of the specification include: filter tube 1, power barrel 2, first mesh cable 3, slide 4, second middle mesh cable 5, second bottom mesh cable 6, top filter tube 7, bottom filter tube 8, middle liquid inlet pipe 9, connecting shaft 10, liquid inlet slot 11, spiral water supply guide plate 12, and liquid discharge spiral groove 13.

[0033] A filtering device for food processing, for example Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown:

[0034] It includes a filter tube 1, a power barrel 2 installed at the top of the filter tube 1, a slag collecting barrel installed at the bottom of the filter tube 1, a connecting shaft 10 installed in the filter tube 1, and a connecting water component installed outside the connecting shaft 10. A liquid inlet is opened on the power barrel 2, and the liquid inlet is generally closed by a cover plate. A slag outlet is opened at the bottom of the slag collecting barrel, and a slag outlet plate is installed to block the slag outlet during filtering.

[0035] A cylindrical accommodating chamber is formed in the filter tube 1, and a connecting shaft hole is coaxially opened on the power barrel 2.

[0036] The connecting water assembly includes a spiral water supply guide plate 12 welded to the outside of the connecting shaft 10 in a spiral shape along the axial direction of the connecting shaft 10 and a connecting water pipe sleeved on the outside of the spiral water supply guide plate 12. The bottom end of the connecting water pipe passes through the slag collecting bucket and extends out of the bottom of the slag collecting bucket. The top of the connecting water pipe is closed and is at the same height as the top of the filter tube 1. The connecting shaft 10 and the spiral water supply guide plate 12 are the same length as the connecting water pipe and can rotate in the connecting water pipe. In this embodiment, a plurality of liquid inlet slots 11 are opened circumferentially on the outer wall of the connecting water pipe located inside the filter tube 1.

[0037] The connecting water pipe includes three sections connected in sequence from bottom to top: bottom filter pipe 8, middle liquid inlet pipe 9 and top filter pipe 7. The liquid inlet slot 11 is opened on the middle liquid inlet pipe 9, and the outer wall of the spiral water supply guide plate 12 fits the inner wall of the bottom filter pipe 8 and the middle liquid inlet pipe 9.

[0038] like Figure 2 As shown, four sets of isolation plate net structures are also installed on the middle liquid inlet pipe 9. Figure 3 and Figure 4 As shown, the specific composition of the same set of isolation plate net structures is shown, which includes, from top to bottom: a top fixed block net, a middle movable block net and a bottom movable block net.

[0039] Specifically, the top screen includes an inner fixed ring plate fixedly mounted on the outer wall of the middle liquid inlet pipe 9, an outer fixed ring plate fixedly mounted on the inner wall of the filter tube 1, and a plurality of first mesh wires 3 fixed between the inner fixed ring plate and the outer fixed ring plate perpendicular to the axial direction of the connecting shaft 10, and the spacing between the first mesh wires 3 is greater than the average size of the raw material particles;

[0040] The structure of the middle movable screen and the bottom movable screen is the same, both of which include an inner movable ring plate rotatably mounted on the outer wall of the middle liquid inlet pipe 9, a plurality of outer movable ring plates rotatably mounted on the inner wall of the filter tube 1, and a second mesh wire fixed between the inner movable ring plate and the outer movable ring plate perpendicular to the axial direction of the connecting shaft 10, the spacing between the second mesh wires is the same as the spacing between the first mesh wires 3, and the first mesh wires 3 and the second mesh wires are parallel to each other. Two first fixed connecting rods parallel to the first mesh wires 3 are also fixedly mounted between the inner fixed ring plate and the outer fixed ring plate, and two second fixed connecting rods parallel to the second mesh wires are also fixedly mounted between the inner movable ring plate and the outer movable ring plate.

[0041] In this embodiment, the first mesh wire 3 and the second mesh wire used are both nylon ropes, and are respectively stretched between the inner fixed ring plate and the outer fixed ring plate, and the inner movable ring plate and the outer movable ring plate. The thickness of the nylon rope is 1mm. At the same time, the thickness of the inner fixed ring plate, the outer fixed ring plate, the inner movable ring plate and the outer movable ring plate is 1cm. The spacing between the adjacent first mesh wire 3 and the second mesh wire, and between the second mesh wire and the second mesh wire is equal to the thickness of the nylon rope, which is slightly smaller than the average size of the raw material. Of course, in other embodiments, nylon ropes of suitable sizes can be selected arbitrarily, and different nylon rope installation spacings can be selected according to actual production, so that screen structures with different aperture sizes can be formed in this way. In this embodiment, the size of the liquid inlet slot 11 is smaller than the average size of the smallest raw material.

[0042] Two of the four groups of isolation plate net structures installed on the outside of the middle liquid inlet pipe 9 are located at both ends of the middle liquid inlet pipe 9, and the remaining two groups of isolation plate net structures are respectively located at the trisection lines of the middle liquid inlet pipe 9. The connecting water pipe is fixed in the filter pipe 1 by installing an outer fixed ring plate, an inner fixed ring plate and a first fixed connecting rod.

[0043] Four groups of slides are respectively provided on the filter tube 1, and each group of slides is arranged relative to each group of isolation plate net structures. Each group of slides includes two slide grooves 4, and each slide groove 4 is fan-shaped, and the angle of the fan shape is 45 degrees. The two ends of the slide grooves 4 between each group of slides are flush. On the outer wall of the outer movable ring plate in each group of isolation plate net structures, a shifting block that can extend out of the slide groove 4 is integrally formed. In this example, the thickness of the slide groove 4 is less than the thickness of the outer movable ring plate, and the outer wall of the outer movable ring plate can completely close the slide groove 4. A positioning plate is also integrally formed at both ends and the middle section of the slide groove 4, and bolt holes are coaxially provided on the shifting block and the positioning plate. The shifting block can be fixed by means of the bolt holes and the bolts. The shifting block, the positioning plate and the bolts form a positioning structure for fixing the middle movable fence and the bottom movable fence. When the staff manually rotates the shift block, the outer movable ring plate will be driven to rotate synchronously, and then the inner movable ring plate will be driven to rotate synchronously through the second fixed connecting rod. During the rotation process, the angle between the second mesh cable and the first mesh cable 3 can be adjusted.

[0044] When the second mesh wire is no longer parallel to the first mesh wire 3, an angle is formed, thereby forming a mesh hole with a variable size. By changing the size of the mesh hole, a barrier net with different apertures is formed. In this example, the second mesh wires in the same group of isolation plate mesh structures can be divided into: a second middle mesh wire 5 and a second bottom mesh wire 6 from top to bottom.

[0045] The spiral water supply guide plates 12 installed in the filter tube of this embodiment all have a double-layer structure. Figure 5 As shown, a continuous liquid discharge spiral groove 13 is provided in the spiral water supply guide plate 12. The liquid containing raw material impurities is initially filtered by the isolation plate mesh structure, and the liquid is secondary filtered through the liquid inlet slot 11 provided on the middle liquid inlet pipe 9. The upper end surface of the spiral water supply guide plate 12 is used for the liquid after the secondary filtration. The upper end surface of the spiral water supply guide plate 12 is also provided with a plurality of filter holes connected with the liquid discharge spiral groove 13 to achieve tertiary filtration, and the liquid after the tertiary filtration is discharged through the liquid discharge spiral groove 13.

[0046] In this embodiment, the spiral water supply guide plate 12 and the drainage spiral groove 13 both extend to the bottom of the connecting water pipe, and a block is installed at the bottom of the connecting water pipe, which can move synchronously with the spiral water supply guide plate 12 and is used to block the spiral water supply guide plate 12.

[0047] The top filter tube 7 extends to the top fixed fence, the bottom filter tube 8 is located below the bottom movable fence, and the outer wall of the connecting water pipe below the bottom filter tube 8 is not provided with a liquid inlet notch 11.

[0048] Furthermore, in this embodiment, a driving structure for driving the connecting shaft 10 to rotate is installed on the top of the power barrel 2. The driving structure includes a rotating shaft coaxially fixedly connected to the connecting shaft 10 and a driving motor fixedly installed on the power barrel 2 and used to drive the rotating shaft to rotate. When the connecting shaft 10 rotates, the spiral water supply guide plate 12 will be driven to rotate synchronously. In addition, a plurality of stirring rods are circumferentially installed on the outer wall of the rotating shaft above the top fixed block net. The rotating spiral water supply guide plate 12 can not only accelerate the liquid to pass through the filter hole into the liquid discharge spiral groove 13, but also drive the liquid in the connecting water pipe to move synchronously during the rotation process. When the liquid inlet slot 11 on the connecting water pipe is blocked on a large scale, the spiral water supply guide plate 12 can push the liquid inside the connecting water pipe to impact the blocked liquid inlet slot 11 to prevent blockage.

[0049] When the present invention is used, before introducing the liquid to be filtered into the liquid inlet, the shifting block of the bottommost isolation plate mesh structure is rotated to make the second middle mesh wire 5 perpendicular to the first mesh wire 3, and the second bottom mesh wire 6 is placed at the diagonal of the rectangular mesh formed by the second middle mesh wire 5 and the first mesh wire 3, so as to form a bottom mesh structure;

[0050] By adjusting the structure of the two intermediate isolation plates, various sizes of raw material impurities can be filtered:

[0051] The mesh size of the blocking net adjusted in the lower isolation plate mesh structure is smaller than the mesh size of the blocking net adjusted in the upper isolation plate mesh structure: the mesh size of the blocking net can be adjusted to be inclined and of different sizes by tilting the second middle mesh wire and the second bottom mesh wire, and the liquid to be filtered is introduced from the liquid inlet after the mesh size of the blocking net is adjusted, wherein the liquid can be wine, beverage, soy sauce, vinegar, etc.;

[0052] At this time, a large number of agglomerated raw material impurities will be retained on the top fixed fence. As the drive motor drives the shaft to rotate, the stirring rod rotates synchronously with the shaft, breaking up the agglomerated raw materials and causing them to fall and cover the isolation plate mesh structure below. The liquid will be filtered multiple times and enter the drain spiral groove 13 for discharge;

[0053] The raw material impurities accumulated in the middle moving fence can be dropped by rotating the outer moving ring plate, and enter the slag collecting bucket for storage, completing multiple filtrations of the liquid, and cleaning and temporary storage of raw material impurities without stopping the machine. After a batch of liquid is filtered, the slag discharge plate at the bottom of the slag collecting bucket is opened to achieve unified cleaning of raw material impurities.

[0054] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
