Description

Technical Field

[0001] This utility model belongs to the field of sodium lactate secondary positive pressure filtration technology, and more specifically, it relates to an auxiliary device for secondary positive pressure filtration. Background Technology

[0002] Sodium lactate is processed after initial filtration or purification, and requires secondary positive pressure filtration using a positive pressure filter to ensure the quality and stability of the final product. A positive pressure filter is a device that achieves solid-liquid separation by applying positive pressure to push the liquid through a filter medium (such as filter cloth). It usually consists of an upper filter chamber, a lower filter chamber, corresponding inlet and outlet ports, and lifting eye bolts that fix the upper and lower parts.

[0003] Existing application number: CN202420350840.X, this utility model discloses a heat-insulating positive pressure filter device, belonging to the field of filter technology, including a filter tank; a heat-insulating layer, including a heat-insulating sleeve, which is fitted over the filter tank and detachably connected to it, with a heat-insulating cavity inside the sleeve, and a liquid inlet component and a liquid outlet component disposed on the sleeve, both of which are in communication with the heat-insulating cavity; and a flow guiding component disposed inside the heat-insulating cavity to guide the liquid within the cavity. This utility model can maintain good heating and heat preservation effects on the filter tank, thereby preventing material solidification and improving the filtration effect.

[0004] Based on the above, during the maintenance of a positive pressure filter, it is necessary to separate the upper and lower filter chambers in order to replace the filter media located at the top of the lower filter chamber. This operation involves flipping multiple lifting eye bolts downwards one by one to disassemble them. After replacing the media, these lifting eye bolts are flipped upwards and the corresponding lifting eye is rotated to tighten the upper and lower filter chambers. This series of tedious steps greatly increases the complexity of the maintenance work and consumes a lot of time. Utility Model Content

This operation involves flipping multiple lifting eye bolts downwards one by one to disassemble the filter, and after replacing the media, flipping these lifting eye bolts upwards and rotating the corresponding lifting eye to tighten the upper and lower filter chambers. This series of cumbersome steps greatly increases the complexity of the maintenance work and consumes a lot of time.

[0006] The purpose and effectiveness of this utility model's auxiliary device for secondary positive pressure filtration are achieved through the following specific technical means:

[0007] An auxiliary device for secondary positive pressure filtration includes a lower main body;

[0008] The support legs are provided in three pieces, which are distributed and fixedly connected to the lower part of the main body.

[0009] An upper main body is disposed on top of a lower main body;

[0010] The mating components are provided in multiple parts, and the multiple mating components are distributed and fixedly connected to the bottom of the upper main body;

[0011] The first slider is provided in two parts, and the two first sliders are respectively slidably connected to the inside of the two rear support legs;

[0012] A movable ring, which is fixedly connected to the outside of the two first sliders;

[0013] An upward-lifting fitting component is disposed at the bottom of the upper main body;

[0014] A falling drive component is disposed above the lower main body.

[0015] Furthermore, the lifting and engaging component includes:

[0016] An operating handwheel is rotatably connected inside a front outrigger.

[0017] A drive bevel gear, which is coaxially and fixedly connected to the rear end of the operating handwheel;

[0018] Driven bevel gear, which is rotatably connected inside a front support leg, and meshes with driving bevel gear.

[0019] Furthermore, the lifting and engaging component also includes:

[0020] A transmission screw is coaxially and fixedly connected to the driven bevel gear, and the transmission screw is rotatably connected inside a front support leg.

[0021] The second slider is slidably connected inside the front support leg, the second slider is threadedly connected to the transmission screw, and the second slider is fixedly connected to the moving ring.

[0022] Furthermore, the lifting and engaging component also includes:

[0023] The fixing box is provided in multiple parts, and the multiple fixing boxes are distributed and fixedly connected inside the moving ring;

[0024] The jacking block is provided in multiple parts, and the multiple jacking blocks are slidably connected inside the multiple fixed boxes.

[0025] Furthermore, the lifting and engaging component also includes:

[0026] A connecting spring is provided, wherein multiple connecting springs are provided, the inner ends of the multiple connecting springs are respectively fixedly connected to the outer side of the multiple push-in blocks, and the outer ends of the multiple connecting springs are respectively fixedly connected to the inside of the multiple fixing boxes;

[0027] The connector is provided in multiple parts, which are distributed and fixedly connected to the outer side of the lower main body;

[0028] The lifting eye bolts are provided in multiple pieces, and the lower ends of the multiple lifting eye bolts are respectively hinged to the interior of multiple connecting pieces.

[0031] A driving magnet is provided, and multiple driving magnets are respectively fixedly connected to the inner end of multiple connecting rods.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] First, when it is necessary to fix the lower body and the upper body, operate the handwheel and combine it with the lifting assembly to drive the moving ring to move upward. The upward movement of the moving ring causes the lifting eye bolts on the moving ring to flip upward. As the multiple jacking blocks move upward, the multiple lifting eye bolts can be pushed into the openings of the multiple mating parts respectively. Then, the lifting eye bolts on the multiple lifting eye bolts can be locked, without having to flip the lifting eye bolts one by one.

[0034] Secondly, when the moving ring moves downward and the jacking block releases the restriction on the eye bolt, the magnetic force of the metal screw in the eye bolt is attracted by the driving magnet, and the eye bolt automatically tilts outward to open. It is no longer necessary to manually open multiple eye bolts outward at once, making the operation simpler and less labor-intensive.

[0035] When the driving ring moves upward, multiple lifting eye bolts simultaneously flip upward and enter the opening of the mating part, eliminating the need for them to flip upward one by one. After the moving ring moves downward and releases the restriction, the driving magnet attracts the metal screw in the lifting eye bolt, causing it to automatically tilt outward and open. This eliminates the need for manual operation, simplifying the operation process and making it more labor-saving and convenient. Attached Figure Description

Detailed Implementation

[0044] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0045] Example 1:

[0046] As attached Figure 1 To be continued Figure 6 As shown:

[0047] This utility model provides an auxiliary device for secondary positive pressure filtration, including a lower main body 1;

[0048] Support legs 101, three support legs 101 are provided, and the three support legs 101 are distributed and fixedly connected to the lower main body 1 below;

[0049] Upper main body 2 is set on top of lower main body 1;

[0050] The mating parts 201 are provided in multiple parts, and the multiple mating parts 201 are distributed and fixedly connected to the bottom of the upper main body 2.

[0051] The first slider 3 has two parts, and the two first sliders 3 are respectively slidably connected to the inside of the two rear support legs 101.

[0052] The movable ring 7 is fixedly connected to the outside of the two first sliders 3;

[0053] The lifting assembly is located at the bottom of the upper main body 2.

[0054] The lifting assembly includes:

[0055] The operating handwheel 5 is rotatably connected to the inside of the front support leg 101;

[0056] The active bevel gear 501 is coaxially and fixedly connected to the rear end of the operating handwheel 5.

[0057] Driven bevel gear 601 is rotatably connected inside the front support leg 101. Driven bevel gear 601 meshes with driving bevel gear 501. The function of driving bevel gear 601 is that turning the operating handwheel 5 can drive driven bevel gear 601 to rotate through the bevel gear transmission mechanism formed by the meshing of driven bevel gear 601 and driving bevel gear 501.

[0058] The lifting assembly also includes:

[0059] The transmission screw 6 is coaxially and fixedly connected to the driven bevel gear 601, and the transmission screw 6 is rotatably connected to the inside of the front support leg 101.

[0060] The second slider 4 is slidably connected inside the front support leg 101. The second slider 4 is threadedly connected to the transmission screw 6 and fixedly connected to the moving ring 7. The function is that when the driven bevel gear 601 rotates, it will drive the moving ring 7 to move up and down through the threaded transmission mechanism formed by the second slider 4 and the transmission screw 6.

[0061] The lifting assembly also includes:

[0062] The fixing box 8 is provided in multiple parts, and the multiple fixing boxes 8 are distributed and fixedly connected inside the moving ring 7.

[0063] The push-in block 9 is configured with multiple parts, and each of the multiple push-in blocks 9 is slidably connected inside the multiple fixed boxes 8. The effect is that the up-and-down movement of the moving ring 7 will drive the fixed box 8 and the push-in block 9 to move up and down synchronously.

[0064] The lifting assembly also includes:

[0065] Connecting spring 901, multiple connecting springs 901 are provided, the inner ends of the multiple connecting springs 901 are respectively fixedly connected to the outer side of the multiple top-feeding blocks 9, and the outer ends of the multiple connecting springs 901 are respectively fixedly connected to the inside of the multiple fixing boxes 8.

[0066] Connector 102, multiple connectors 102 are provided, and multiple connectors 102 are distributed and fixedly connected to the outside of the lower main body 1;

[0067] The lifting eye bolt 103 is provided in multiple parts, and the lower ends of the multiple lifting eye bolts 103 are respectively hinged to the interior of multiple connecting parts 102. The function is that when the moving ring 7 moves downward, the push block 9 will release the restriction on the lifting eye bolt 103, so that the lifting eye bolt 103 can flip down and open along the hinge part with the connecting part 102 as the axis. The connecting spring 901 can ensure that the push block 9 moves outward a certain distance when passing the hinge protrusion of the lifting eye bolt 103 and the connecting part 102, and then can continue to move downward without being stuck.

[0068] The specific usage and function of this embodiment are as follows:

[0069] In use, if it is necessary to separate the lower main body 1 and the upper main body 2, first twist the lifting ring above the lifting eye bolt 103 upwards to release the lifting ring from pressing on the mating part 201. Then, turn the operating handwheel 5. This will drive the driven bevel gear 601 to rotate through the bevel gear transmission mechanism formed by the meshing of the driven bevel gear 601 and the driving bevel gear 501. The rotation of the driven bevel gear 601 will drive the moving ring 7 to move downwards through the threaded transmission mechanism formed by the second slider 4 and the transmission screw 6. The downward movement of the moving ring 7 will drive the fixed box 8 and the push block 9 to move downwards synchronously, which will release the push block 9 from restricting the lifting eye bolt 103, thus allowing the lifting eye bolt 103 to move along the connecting part. The hinge part of 102 flips down and opens. The connecting spring 901 ensures that the push block 9 moves a certain distance outward when passing the hinge protrusion of the eye bolt 103 and the connecting piece 102, and can then continue to move downward to avoid being stuck. After that, the upper body 2 can be removed upward. When the upper body 2 needs to be installed on the lower body 1, simply turn the operating handwheel 5 in the opposite direction. Then, the upward movement of the moving ring 7 will cause the eye bolt 103 on the moving ring 7 to flip upward. As the multiple push blocks 9 move upward, the multiple eye bolts 103 are pushed into the openings of the multiple mating parts 201 respectively. Then, the eye bolts on the multiple eye bolts 103 are locked.

[0070] Example 2:

[0071] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, it also includes a falling drive component, which is positioned above the lower main body 1.

[0072] The falling drive components include:

[0073] Connecting rod 10, the connecting rod 10 has an "L" shaped structure, and multiple connecting rods 10 are provided, which are distributed and fixedly connected to the moving ring 7;

[0074] A drive magnet 1001 is provided, and multiple drive magnets 1001 are respectively fixedly connected to the inner end of multiple connecting rods 10.

[0075] The specific usage and function of this embodiment are as follows:

[0076] When the moving ring 7 moves downward and the jacking block 9 releases its restriction on the eye bolt 103, the connecting rod 10 and the driving magnet 1001 move downward synchronously. When the jacking block 9 moves below the hinged part between the eye bolt 103 and the connecting piece 102, the eye bolt 103 automatically tilts outward and opens due to the magnetic attraction of the metal screw in the eye bolt 103 by the driving magnet 1001. This eliminates the need for manual opening of multiple eye bolts 103 at once, making the operation simpler and less strenuous.
