Description

Technical Field

[0001] This application relates to the field of chemical separation technology, and in particular to a TGIC salt filtration device with adjustable filter cloth. Background Technology

[0002] In modern TGIC coating and salt bath processes, the salt filtration unit is a key piece of equipment to ensure the purity of the salt solution and the stability of the process. This unit is typically used to filter molten salt solutions containing impurities to prevent these impurities from entering subsequent processes or products. It is widely used in pre-coating treatment, metal surface treatment, and chemical salt production. With the increasing demands for uniform film thickness and coating quality in TGIC coatings, higher requirements are placed on the filtration efficiency, reliability, and ease of maintenance of the salt filtration unit. This is especially true on production lines where multiple sizes of filter cloth and filter cartridges are frequently replaced. The salt filtration unit must be able to quickly adapt to different filter cloth sizes, ensure a secure seal and prevent leakage, and minimize downtime for maintenance.

[0003] Existing TGIC (ThinPressed Filter) systems have significant shortcomings in terms of clamping and replacing filter cloth. They typically employ a single-size fixed clamping ring or threaded fastening method. This structure is only suitable for filter cloths of a predetermined size and cannot be flexibly adjusted to accommodate filter media of different diameters or thicknesses. This necessitates the preparation of multiple sets of specialized clamps when replacing filter cloth, increasing equipment investment and the workload of cloth replacement. Furthermore, the installation and disassembly of the filter cartridge largely rely on manual alignment and bolt tightening, which is not only time-consuming but also poses a high risk when operating in high-temperature or toxic environments. These deficiencies result in low efficiency in replacing filter media and high maintenance costs during actual use. Instable clamping can also lead to filter cloth loosening or leakage, affecting filtration efficiency and production safety. Utility Model Content

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses an adjustable filter cloth TGIC salt filtration device.

[0028] Please see Figures 1 to 4 An adjustable TGIC salt filtration device includes a clamping structure 2 for holding filter cloths of different specifications and a fixing structure 3 for quick filter cartridge replacement. The bottom of the clamping structure 2 is fixedly connected to the fixing structure 3, and a cylinder 1 is installed on the outside of the fixing structure 3. The clamping structure 2 includes a cylinder 21, a rubber pad 27 is fixedly connected to the top of the cylinder 21, a ring 26 is fixedly connected to the top of the rubber pad 27, a fixing ring 28 is fixedly connected to the top of the ring 26, a plurality of connecting blocks 210 are fixedly connected to the top of the fixing ring 28, a support column 29 is fixedly connected to one side of the fixing ring 28, a slide rod 25 is fixedly connected to the top of the support column 29, the slide rod 25 is slidably connected inside the slider 23, a limit ring 22 is fixedly connected to the top of the connecting block 210, and a clamping block 24 is provided on one side of the slide rod 25.

[0029] It should be explained that the cylinder 1 provides space for filtration operations, and the clamping structure 2 inside is used to adapt to filter cloths of different specifications. The top of the cylinder 21 is equipped with a rubber pad 27 to buffer the pressure of the filter cloth and prevent the filter cloth from being damaged during clamping. The rubber pad 27 is connected in sequence to a ring 26 and a fixing ring 28 to provide stable support for the clamping components. The top of the fixing ring 28 is connected to a limiting ring 22 via multiple connecting blocks 210, which can limit the displacement range of the filter cloth and ensure filtration stability. One side of the fixing ring 28 is connected to a sliding rod 25 via a support column 29. The sliding rod 25 slides in the slider 23, which drives the clamping block 24 next to the sliding rod 25 to move. By adjusting the position of the clamping block 24, filter cloths of different sizes can be flexibly clamped to ensure that the filter cloth fits tightly with the device and ensures the salt filtration effect. The fixing structure 3 connected to the bottom of the clamping structure 2 is used for quick replacement of the filter cartridge and optimizes the maintenance process of the salt filtration device.

[0030] Please see Figures 1 to 4The fixed structure 3 includes a base ring 31, a placement ring 33 is fixedly connected to the upper side of the base ring 31, a limiting groove 36 is opened inside the placement ring 33, a sliding groove 34 is provided on one side of the limiting groove 36, a slider 32 is slidably connected inside the limiting groove 36, and a protective ring 35 is provided at the upper end of the placement ring 33.

[0031] It should be explained that the fixed structure 3 allows for quick assembly and disassembly of the filter cartridge and ensures stable operation of the device. The base ring 31 provides a stable support point for the entire structure, and the upper fixed placement ring 33 provides a placement space for the filter cartridge 4. The limiting groove 36 inside the placement ring 33 can precisely limit the movement trajectory of the slider 32, ensuring that the slider 32 does not deviate when sliding. The sliding groove 34 on one side of the limiting groove 36 serves as the loading and unloading channel for the slider 32, facilitating its insertion or removal. The slider 32 slides within the limiting groove 36 and can cooperate with the adapter structure at the bottom of the filter cartridge 4, allowing for quick replacement of the filter cartridge. The protective ring 35 at the upper end of the placement ring 33 can prevent the filter cartridge 4 from shaking and shifting during operation, and can also block external debris from entering, ensuring stable operation of the filter cartridge 4 and improving the reliability and durability of the salt filtration device.

[0032] Please see Figures 1 to 4 The bottom of the cylinder 1 is fixedly connected to a base ring 2 7, and the upper end of the base ring 2 7 is provided with a circular ring 2 5.

[0033] It should be explained that the cylinder 1 provides a closed space for operations such as filter cloth filtration and salt solution separation. The base ring 2 7 fixedly connected to its bottom directly contacts the placement surface, increasing the contact area between the device and the support surface, dispersing the weight pressure of the cylinder 1 and the internal materials, preventing the cylinder 1 from sinking or tilting due to uneven force, and ensuring that the device is placed stably. The circular ring 2 5 set at the upper end of the base ring 2 7 can strengthen the connection strength between the base ring 2 7 and the upper structure, improve the overall structural stability, and make the salt filtration operation orderly and efficient.

[0034] Please see Figures 1 to 4 A second ring 5 is fixedly connected to the upper end of the cylinder 1, and a conveying port 6 is fixedly connected to the upper end of the second ring 5. The cylinder 1 is located at the bottom of the conveying port 6.

[0035] It should be explained that the ring 2 5 fixedly connected to the upper end of the cylinder 1 strengthens the structural strength of the opening at the upper end of the cylinder 1, prevents deformation under long-term stress, and provides stable support for the installation of the upper conveying port 6. The conveying port 6 fixed at the upper end of the ring 2 5 allows the salt solution to flow smoothly and evenly into the cylinder 1, reducing the risk of splashing and clogging, and ensuring a smooth salt filtration process.

[0036] Please see Figures 1 to 4 The bottom of the cylinder 1 is fixedly connected to a base ring 31, and a base ring 7 is provided at the bottom of the base ring 31.

[0037] It should be explained that the base ring 31 fixedly connected to the bottom of the cylinder 1 increases the contact area to distribute the weight of the cylinder 1 and the internal material, preventing the cylinder 1 from sinking or tilting due to excessive local stress, and ensuring that the device is placed stably. The base ring 7 set at the bottom of the base ring 31 expands the support range of the bottom of the device, enhances the stability of the device in complex working environments, reduces the impact of vibration on the salt filtration process, and allows the salt filtration operation to be carried out stably and continuously.

[0038] Please see Figures 1 to 4 The upper end of the base ring 31 is provided with a sliding groove 34, and the upper end of the sliding groove 34 is provided with a protective ring 35.

[0039] It should be explained that in the adjustable filter cloth TGIC salt filter device, the base ring 31 is an important support for the bottom structure of the device. The slide groove 34 set at the upper end provides a precise sliding path for the internal components of the device, ensuring that the components do not deviate in direction and are positioned more accurately when moving, which facilitates subsequent operations such as disassembling and assembling the filter cartridge. The protective ring 35 at the upper end of the slide groove 34 can prevent external dust, impurities and other debris from falling into the slide groove 34, avoiding affecting the smoothness of the component sliding, limiting and protecting the internal sliding components, preventing the components from falling out of the slide groove 34 range when sliding, and ensuring the stable operation of the bottom structure of the device.

[0040] Please see Figures 1 to 4 A circular ring 2 5 is fixedly connected to the outer side of the protective ring 35, and a filter cylinder 4 is fixedly installed inside the cylinder 1.

[0041] It should be explained that a filter cartridge 4 is fixed inside the cylinder 1. When the salt solution flows through, it allows the pure filtrate to pass through, completing the solid-liquid separation. The outer side of the protective ring 35 below the filter cartridge 4 is fixedly connected to the circular ring 2 5, which can enhance the structural strength of the protective ring 35. At the same time, it helps to connect the protective ring 35 with other components, making the bottom structure of the device more stable, reducing the risk of loosening or displacement of components, creating a stable environment for the normal operation of the filter cartridge 4, and enabling the salt filtration operation to be carried out continuously and efficiently.

[0042] The implementation principle of the adjustable filter cloth TGIC salt filtration device in this application embodiment is as follows:

[0043] First, select a filter cloth of suitable specifications and place it on top of the cylinder 21 of the clamping structure 2. Drive the slide bar 25 to slide within the slider 23, causing the clamping block 24 to move towards the edge of the filter cloth. During this process, the rubber pad 27 buffers the clamping pressure on the filter cloth, preventing damage, while the ring 26 and the fixing ring 28 provide stable support for the movement of the clamping block 24. Once the clamping block 24 has moved to the appropriate position, the edge of the filter cloth is firmly clamped, and the limiting ring 22 further restricts the displacement range of the filter cloth, ensuring a tight fit between the filter cloth and the device, thus completing the filter cloth installation.

[0044] Secondly, the salt solution flows evenly and smoothly into the interior of cylinder 1 through the inlet 6 at the top of cylinder 1. The salt solution first flows over the surface of the filter cloth, which traps solid impurities in the salt solution due to its porous structure, while the pure filtrate passes through the pores of the filter cloth and enters the filter cylinder 4 below. The filter cylinder 4 further filters the filtrate a second time to ensure that the filtrate reaches a higher purity, achieving effective separation of solids and liquids in the salt solution.

[0045] Finally, when the filtration efficiency of filter cartridge 4 decreases due to prolonged use or impurity accumulation, it needs to be replaced. At this time, the operator pushes slider 2 32 into the limiting groove 36 inside the placement ring 33. Sliding slider 2 32 moves along a preset trajectory, separating from the fitting structure at the bottom of filter cartridge 4, thus releasing the filter cartridge 4 from its fixation. The filter cartridge 4 can then be easily removed from the placement ring 33. When replacing with a new filter cartridge, the new filter cartridge is placed on the placement ring 33, and slider 2 32 is pushed again into the limiting groove 36, allowing it to engage with the fitting structure at the bottom of filter cartridge 4, completing the quick fixation of filter cartridge 4. The protective ring 35 prevents the filter cartridge 4 from shaking or shifting during operation and blocks external debris from entering, ensuring stable operation of filter cartridge 4, reducing device maintenance time, and improving salt filtration efficiency.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
