Description

Technical Field

[0001] This utility model relates to the technical field of pectin liquid multi-stage fine filtration device, specifically a pectin liquid multi-stage fine filtration device. Background Technology

[0002] The multi-stage filtration device for pectin solution can effectively remove impurities, fine fruit residue, small molecule impurities, and inorganic salts from the pectin solution through multi-stage filtration, thereby improving the purity of the pectin solution.

[0003] For example, a multi-stage fine filtration device for pectin liquid, authorized by publication number "CN221579885U", achieves multi-stage filtration by setting cylindrical filter screens of different diameters and combining them with the conical lower part of the filter box. Since the filter screens are vertically arranged, individual screens can be easily removed, thus solving the problem of individual screen replacement in existing multi-stage pectin filtration equipment. However, in the use of this multi-stage fine filtration device, multiple interlocking screens concentrate the filtration of pectin liquid at the bottom of the screens. When the bottom of the screens becomes clogged, the pectin liquid in the multi-stage fine filtration device cannot continue to be filtered, requiring cleaning and secondary filtration. Utility Model Content

[0004] The purpose of this invention is to solve the problem that pectin liquid cannot be filtered further in a multi-stage fine filtration device, which requires cleaning and secondary filtration. Therefore, a multi-stage fine filtration device for pectin liquid is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A multi-stage fine filtration device for pectin liquid is designed, comprising a shell and a support. The outer wall of the shell is fixedly connected to the inner wall of the support. A fine filtration structure is connected to the inner wall of the shell. Multiple curved plates are fixedly connected to the four corners of the top of the shell. A material injection structure is connected to the inner wall of the curved plates. Curved blocks are fixedly connected to the top of the left and right sides of the shell.

[0007] In this configuration, the bottom of the outer shell is connected to the top. After the pectin liquid enters through the top of the outer shell 1 and is filtered, it will be discharged directly at the bottom of the outer shell.

[0008] Preferably, the fine filtration structure includes a square frame and vertical plates. The outer wall of the square frame is fixedly connected to the lower part of the inner wall of the outer shell. The top left and right sides of the square frame are respectively attached to the bottom of the two vertical plates. Multiple mesh plates are fixedly connected to the inner sides of the two vertical plates. A first round rod is fixedly connected to the upper inner side of the two vertical plates respectively.

[0009] This setting, with the screen plate angled, greatly increases the contact area between the pectin liquid and the screen plate, ensuring that the screen plate effectively filters the pectin liquid.

[0010] Preferably, a base is fixed to each of the four bottom corners of the bracket.

[0011] In this design, the base at the bottom of the bracket provides support, and the stability of the casing is ensured through the cooperation of the bracket and the base.

[0012] Preferably, the injection structure includes a top cover and a material inlet. The outer wall of the top cover is rotatably connected to the inner wall of the curved plate, the top of the top cover is connected to the bottom of the material inlet, and a second round rod is fixedly connected to the front and rear sides of the material inlet respectively.

[0013] This feature allows the top cover to flip upwards by gripping the second round rod and pulling it upwards, with the pulling force being transmitted to the material inlet.

[0014] Preferably, the bottom of the top cover fits into the top of the outer casing.

[0015] Preferably, the inner sides of the two top covers are fitted together.

[0016] The multi-stage fine filtration device for pectin solution proposed in this utility model has the following advantages: Pectin solution is poured into the inlet through the fine filtration structure. At this point, the pectin solution mainly contacts the uppermost mesh plate. Because the mesh plate is inclined in four directions, the pectin solution flows downwards along the inclined outer wall of the mesh plate, leaving larger fruit residue at the top. Then, the pectin solution passes through the uppermost mesh plate, where it contacts the middle mesh plate, leaving smaller fruit residue at the top. Finally, the pectin solution passes through the middle mesh plate and contacts the lowermost mesh plate, filtering out even finer impurities. This changes the original method of small filtration contact area, greatly increasing the contact range between the pectin solution and the mesh plates, ensuring continuous filtration of the pectin solution in the multi-stage fine filtration device, and reducing the need for secondary filtration after cleaning.

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] Please see Figure 1-5 In this embodiment, a pectin liquid multi-stage fine filtration device includes a shell 1 and a support 5. The outer wall of the shell 1 is fixedly connected to the inner wall of the support 5. The bottom of the shell 1 has an opening that communicates with the top. The inner wall of the shell 1 is connected to a fine filtration structure 2. Multiple curved plates 4 are fixedly connected to the four corners of the top of the shell 1. The inner wall of the curved plates 4 is connected to a material injection structure 3. Curved blocks 7 are fixedly connected to the top of the left and right sides of the shell 1.

[0025] The fine filter structure 2 includes a square frame 201 and vertical plates 202. The outer wall of the square frame 201 is fixedly connected to the lower part of the inner wall of the outer shell 1. The square frame 201 supports the vertical plates 202. The top left and right sides of the square frame 201 are respectively attached to the bottom of the two vertical plates 202. Multiple mesh plates 203 are fixedly connected to the inner side of the two vertical plates 202. The mesh plates 203 are made of stainless steel. A first round rod 204 is fixedly connected to the upper inner side of the two vertical plates 202. The first round rod 204 facilitates the vertical plates 202 to move up and down.

[0026] Pectin solution is poured into the feed inlet 302 through the fine filtration structure 2. At this time, the pectin solution will mostly come into contact with the uppermost screen plate 203. Since the screen plate 203 is inclined in four directions, the pectin solution will flow downward along the inclined outer wall of the screen plate 203, leaving large fruit residues at the top. Then the pectin solution passes through the uppermost screen plate 203, where it comes into contact with the middle screen plate 203, leaving smaller fruit residues at the top. Then the pectin solution passes through the middle screen plate 203 and comes into contact with the lowermost screen plate 203, filtering out even finer impurities in the pectin solution. This changes the original method of small filtration contact area, greatly increasing the contact range between the pectin solution and the screen plate, ensuring continuous filtration of pectin solution in the multi-stage fine filtration device, and reducing the need for secondary filtration after cleaning.

[0027] The four corners of the bottom of the bracket 5 are respectively fixed with bases 6. The injection structure 3 includes a top cover 301 and a material port 302. The outer wall of the top cover 301 is rotatably connected to the inner wall of the curved plate 4. The top plate 301 is rotated by the pin on the inner wall of the curved plate 4 under force. The top of the top cover 301 is connected to the bottom of the material port 302. The front and rear sides of the material port 302 are respectively fixed with second round rods 303. The bottom of the top cover 301 is in contact with the top of the outer shell 1. The inner sides of the two top covers 301 are in contact with each other.

[0028] Working principle:

[0029] Installation of a multi-stage fine filtration system for pectin solution:

[0030] Hold the second round rod 303 and pull it. At this time, the second round rod 303, together with the material port 302, opens the top cover 301 upward. At the same time, the outer wall of the top cover 301, together with the inner wall pin of the curved plate 4, rotates, so that the top of the outer shell 1 opens. At this time, the top of the top cover 301 is in contact with the top of the curved block 7. Then, hold the first round rod 204 and gradually insert the vertical plate 202 into the outer shell 1 from top to bottom. When the vertical plate 202 cannot be lowered, it means that the bottom of the vertical plate 202 is in contact with the top of the square frame 201. Then, flip the top cover 301 inward so that the bottom of the top cover 301 is in contact with the top of the outer shell 1.

[0031] The multi-stage fine filtration device for pectin solution is in operation:

[0032] Place the container below the outer shell 1, and pour the pectin solution into the inlet 302. At this time, the pectin solution will mostly come into contact with the uppermost mesh plate 203. Since the mesh plate 203 is inclined in four directions, the pectin solution will flow downward along the inclined outer wall of the mesh plate 203, leaving the larger fruit residue at the top. Then, the pectin solution passes through the uppermost mesh plate 203, where it comes into contact with the middle mesh plate 203, leaving the smaller fruit residue at the top. Then, the pectin solution passes through the middle mesh plate 203 and comes into contact with the lowermost mesh plate 203, filtering out the finer impurities in the pectin solution, completing the multi-stage fine filtration process. Finally, the pectin solution is discharged through the lowermost mesh plate 203 at the bottom of the outer shell 1 and falls into the container. Then, the container can be removed.

[0033] Cleaning of pectin solution multi-stage fine filtration device:

[0034] To perform the above operations, flip the top cover 301 open, then hold the first round rod 204 and lift it upwards, causing the first round rod 204 to move upwards along with the vertical plate 202, gradually disengaging it from the interior of the outer shell 1. Then, rinse the mesh plate 203 on the inner side of the vertical plate 202 to remove the pectin particles adhering to the surface of the mesh plate 203. Next, rinse the interior of the outer shell 1 with water, allowing the water to drain out at the bottom of the outer shell 1. The drained water is not a harmful substance and can be left to air dry on the ground. After the outer shell 1 and the mesh plate 203 have dried, insert the vertical plate 202 and the mesh plate 203 back into the outer shell 1, and flip the top cover 301 inwards to cover the top of the outer shell 1.
