Description

Technical Field

[0001] This utility model relates to the field of flusulfanil hydrochloride production, and specifically to a flusulfanil hydrochloride filtration and separation device. Background Technology

[0002] In existing filtration and separation processes for flusulfanilamide aqueous solutions, conventional filtration devices are typically used. However, these conventional devices have the following main problems:

[0003] During the filtration process, sediment accumulates on the filter layer. However, due to the limited pore size of the filter layer, it is impossible to completely remove the moisture from the sediment. This results in the filtered sediment still containing a high moisture content, affecting subsequent processing and utilization.

[0004] Once the sediment on the filter layer accumulates to a certain level, the filter layer needs to be replaced. However, the filter layer replacement process in traditional devices is relatively complex and cumbersome, requiring shutdown and manual cleaning, which increases operation time and labor intensity.

[0005] Because the filter layer is prone to clogging, the filtration speed gradually decreases, affecting overall production efficiency. In addition, frequent replacement of the filter layer also increases production costs.

[0006] Existing equipment lacks an effective pressing function, which cannot further remove moisture from the sediment, resulting in resource waste and increased processing costs. Utility Model Content

[0007] The main objective of this invention is to provide a filtration and separation device for flusulfanilamide aqueous solution, thereby solving the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: it includes a collecting cone, a filter cylinder is fixed on the collecting cone, the bottom of the filter cylinder is triangular, and there are hinged rotating perforated plates on both sides of the filter cylinder. A filter bag is fitted on the bottom of the filter cylinder, and the two ends of the filter bag abut against the filter cylinder through the perforated plates.

[0009] Rotating the perforated plate allows you to press the sediment inside the filter bag.

[0010] Preferably, the outer side of the filter cartridge is fixedly connected to the collection cone by multiple support pillars.

[0011] Preferably, a storage tank is also provided, which is located above the filter cylinder. A first valve is provided at the discharge port at the bottom of the storage tank, and the discharge port is directly opposite the filter cylinder.

[0012] Preferably, a rotating shaft is fixed at the bottom of the filter cartridge, and the end of the perforated plate is fitted onto the rotating shaft for rotation.

[0013] Preferably, a pushing mechanism is provided between the orifice plate and the collecting cone, wherein the cylinder end of the pushing mechanism is hinged to the collecting cone, and the piston rod end is hinged to the orifice plate.

[0014] Preferably, the pushing mechanism is a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0015] Preferably, a second valve is fixed at the discharge port at the bottom of the collecting cone.

[0016] This utility model provides a filtration and separation device for flusulfanil aqueous solution, which has the following advantages:

[0017] 1. Filtering with filter bags effectively separates solid precipitates and liquid components from flumethrin aqueous solution, ensuring high purity of the filtered liquid. The filter cartridge is designed in a three-dimensional triangular shape, which helps precipitates concentrate in the center of the filter bag, reducing clogging of the filter layer and improving filtration speed.

[0018] 2. By pressing the precipitate inside the filter bag using a rotating perforated plate, the moisture in the precipitate can be further removed, increasing its dryness. This pressing process not only reduces the moisture content but also improves the precipitate's recovery rate and lowers processing costs.

[0019] 3. The filter bag is fixed to the filter cylinder at both ends by perforated plates. When replacing the filter bag, simply rotate the perforated plates to easily remove it, greatly reducing operation time and labor intensity. This simplifies the filter bag replacement process, reduces downtime caused by filter bag replacement, and improves production efficiency. Attached Figure Description

[0027] like Figures 1-5 As shown, a flusulfanilamide aqueous solution filtration and separation device includes a collecting cone 4, a filter cylinder 3 fixed on the collecting cone 4, the bottom of the filter cylinder 3 is triangular, and the two sides are provided with hinged rotating perforated plates 8. A filter bag 9 is sleeved on the bottom of the filter cylinder 3, and the two ends of the filter bag 9 abut against the filter cylinder 3 through the perforated plates 8.

[0028] Rotating the perforated plate 8 will press the sediment inside the filter bag 9.

[0029] Flufenoxam aqueous solution is introduced from the top of the filter cylinder 3. The solution passes through the filter bag 9 and the perforated plate 8 into the collecting cone 4. The precipitate is isolated and collected by the filter bag 9. After the filtration and separation operation is completed, rotating the perforated plates 8 on both sides contracts, which can press the precipitate in the filter bag 9 and squeeze out the aqueous solution from the precipitate. The precipitate can then be treated by replacing the filter bag 9. The filter bag 9 unfolds to match the bottom triangle of the filter cylinder 3, and both ends of the filter bag 9 are fixed to the filter cylinder 3 by the rotating perforated plates 8.

[0030] Flufenoxam aqueous solution is added from the top of filter cartridge 3. The solution is filtered through filter bag 9, separating the liquid portion from the solid precipitate. The filtered liquid flows into the collecting cone 4 below, while the solid precipitate remains inside filter bag 9. After filtration, pressure can be applied to the precipitate inside filter bag 9 by rotating the perforated plate 8, effectively pressing the precipitate. This process helps reduce the moisture content of the precipitate, making subsequent processing easier. After one filtration and pressing operation, filter bag 9 containing the precipitate can be removed and replaced with a new filter bag for the next cycle.

[0031] High-efficiency separation: The effective filtration of filter bag 9 allows for rapid separation of solids from liquids in aqueous solutions. Easy operation: A simple mechanical structure enables the pressing of sediments, making operation simple and maintenance costs low. Easy cleaning: The design of filter bag 9 makes sediment collection and cleaning simple and quick, reducing cleaning and maintenance time.

[0032] Preferably, the filter cartridge 3 is fixedly connected to the collecting cone 4 via multiple support pillars 5 on its outer side. The filter cartridge 3 and the collecting cone 4 are coaxially arranged so that the filtered water at the bottom of the filter cartridge 3 can smoothly enter the collecting cone 4.

[0033] The filter cartridge 3 is fixedly connected to the collecting cone 4 by multiple support pillars 5. These support pillars not only provide necessary support, ensuring the stability and structural strength of the filter cartridge 3, but also guarantee the robustness of the entire device. The filter cartridge 3 and the collecting cone 4 are coaxially arranged, which ensures that the filtered water can flow smoothly into the collecting cone 4, avoiding problems such as poor fluid flow or leakage caused by eccentricity.

[0034] Preferably, a storage tank 1 is also provided, which is located above the filter cylinder 3. A first valve 2 is provided at the discharge port at the bottom of the storage tank 1, and the discharge port is directly opposite the filter cylinder 3. Opening the first valve 2 allows the flumethrin aqueous solution in the storage tank 1 to enter the filter cylinder 3 for filtration and separation.

[0035] Preferably, a rotating shaft 10 is fixed at the bottom of the filter cylinder 3, and the end of the perforated plate 8 is sleeved on the rotating shaft 10 for rotation. The filter cylinder 3 is a three-dimensional triangle, with the rotating shaft 10 fixed between its two ends. The ends of the perforated plates 8 on both sides are sleeved on the rotating shaft 10, and the other end of the perforated plate 8 holds the filter bag 9 against the filter cylinder 3 for fixation.

[0036] Preferably, a pushing mechanism 6 is provided between the orifice plate 8 and the collecting cone 4, wherein the cylinder end of the pushing mechanism 6 is hinged to the collecting cone 4, and the piston rod end is hinged to the orifice plate 8.

[0037] Hinges are fixed to both sides of the outer side of the orifice plate 8 and the top of the collecting cone 4. The two ends of the pushing mechanism 6 are respectively hinged to the hinges by pins. The pushing mechanism 6 can drive the rotation of the orifice plate 8.

[0038] Preferably, the jacking mechanism 6 is a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The appropriate type can be selected based on the site conditions, making it widely applicable.

[0039] Preferably, a second valve 7 is fixedly installed at the discharge port at the bottom of the collecting cone 4. After the flumethrin aqueous solution is filtered and separated, opening the second valve 7 allows the flumethrin to be transferred.

[0040] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
