Description

Technical Field

[0001] This utility model relates to the field of magnesium ammonium phosphate precipitate filtration equipment, and in particular to a vacuum filter barrel. Background Technology

[0002] In the production of S-adenosylmethionine disulfonate, the pretreatment process requires filtering magnesium ammonium phosphate precipitate during the alkali adjustment stage. Due to the very fine particle size of the precipitate, a 0.45-micron layered filter membrane is generally used. However, with the increase in production capacity, this filtration method can no longer meet the production needs because the filtration speed is slow, the removal of filter residue takes a long time, and it requires the cooperation of three people to complete the task.

[0003] The original stacked filter equipment also has the following disadvantages: 1. Long filtration time and low capacity. Because this equipment uses pumps to circulate the liquid, causing the filter cake to slowly form after passing through each layer of filter membranes, each batch requires 2 hours to produce. 2. Inconvenient filter cake removal. Due to the stacked filtration, three people are needed to remove the filter cake and bag it; otherwise, filter cake leakage will occur, affecting the environment. 3. Increased labor costs. Utility Model Content

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a suction filter bucket, specifically including a bucket body assembly 100, which includes a bucket wall 101, a bucket bottom 102 fixed to the lower part of the bucket wall 101, and a mesh plate 103 fixed inside the bucket wall 101 and located above the bucket bottom 102; and a filter bag fixing assembly 200, which includes a fixing seat 201 fixed to the upper part of the inner wall of the bucket wall 101, a fixing block 202 slidably disposed in the fixing seat 201, and a card seat 203 fixed to the inner wall of the bucket wall 101 and located below the fixing seat 201.

[0027] It should be noted that a reinforcing plate is fixed between the perforated plate 103 and the bottom of the bucket 102 for supporting the perforated plate 103; an infusion pipe is connected to the bottom of the bottom of the bucket 102.

[0028] Furthermore, the fixing seat 201 includes a seat portion 201a and a connecting portion 201b that is fixed between the seat portion 201a and the barrel wall 101.

[0029] It should be noted that the upper surface of the seat 201a and the upper surface of the connecting part 201b can be flush, and the lower surface of the seat 201a is much deeper than the lower surface of the connecting part 201b.

[0030] The connecting part 201b can be as follows: Figure 3 The two symmetrical blocks shown can also be composed of multiple blocks, but the connecting part 201b cannot completely cover the space between the seat part 201a and the barrel wall 101, and a gap must be left.

[0031] Furthermore, the seat 201a is provided with a sliding groove K-1 that passes through the seat 201a, and a limiting cavity K-2 located in the middle of the sliding groove K-1.

[0032] It should be noted that both the slide groove K-1 and the limiting cavity K-2 are fan-shaped, and the thickness of the limiting cavity K-2 is greater than the thickness of the slide groove K-1.

[0033] Preferably, the card holder 203 is fixed below the connecting part 201b; the card holder 203 is provided with a card slot K-3.

[0034] It should be noted that the card slot K-3 is a fan-shaped slot, and the length of the slide K-1 is longer than the length of the card slot K-3.

[0035] In this embodiment, after the filter bag is fixed inside the barrel wall 101, the bottom of the filter bag is supported by the mesh plate 103. After the filter residue containing magnesium ammonium phosphate precipitate is transported to the suction filter barrel, the filter residue is filtered by the filter bag. The filtered liquid flows to the bottom of the barrel 102 after passing through the mesh plate 103 and is transported to other equipment through the infusion pipeline.

[0036] Example 2

[0037] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the fixing block 202 includes a sliding part 202a that is slidably disposed in the slide groove K-1, a pressing part 202b that is fixed to the end of the sliding part 202a and extends away from the barrel wall 101, and a locking part 202c that is fixed to the end of the sliding part 202a and extends close to the barrel wall 101.

[0039] It should be noted that the pressure part 202b can be as follows: Figure 4 The trapezoid shown can also be a circle or other shapes that are easy for the user to press. The pressing part 202b should have fewer sharp edges to prevent the user from being cut when pressing the pressing part 202b.

[0040] Card section 202c can be as follows Figure 4 The trapezoidal shape shown has rounded corners at the edges of the card part 202c to prevent damage to the filter bag.

[0041] Furthermore, the fixing block 202 also includes a limiting part 202d that is fixed in the middle of the sliding part 202a and slidably disposed in the limiting cavity K-2.

[0042] It should be noted that the limiting part 202d protrudes from the surfaces of the pressing part 202b and the locking part 202c, and is adapted to the shape of the limiting cavity K-2, preferably in the shape of a fan, to facilitate sliding.

[0043] In this embodiment, when the filter bag is placed inside the barrel wall 101 and needs to be fixed, the operator needs to pull the edge of the filter bag to between the seat 201a and the barrel wall 101 (i.e. below the connecting part 201b). After that, the operator needs to push the pressing part 202b so that the locking part 202c locks the edge of the filter bag into the locking groove K-3. At this time, the edge of the filter bag can present a "convex" shape, which can form good friction with the locking seat 203 to prevent slippage. The friction between the filter bag and the locking part 202c can fix the entire fixing block 202, thereby limiting the sliding of the fixing block 202.

[0044] It should also be noted that when it is necessary to remove the filter bag, the operator only needs to push the pressing part 202b in the opposite direction to release the filter bag from the fixation.

[0045] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
