Description

Technical Field

[0001] This utility model belongs to the technical field of filtration devices, and in particular relates to a filtration device for large-scale production. Background Technology

[0002] In the production of food, oils, beverages, and pharmaceutical intermediates, decolorization and filtration processes are frequently used. Currently, powdered activated carbon is commonly used in the food, pharmaceutical, and chemical industries for decolorization and filtration to improve product purity and color. Publication number CN219942003U discloses an automatic decolorization and filtration device, including a decolorizing machine and a filter, connected by a connecting pipe. The bottom of the filter is equipped with a discharge hopper, and the interior of the discharge hopper is equipped with a cleaning structure, which includes an infusion pipe. The infusion tube is horizontally installed inside the hopper, and a nozzle is installed in the middle of the infusion tube inside the hopper. The automatic decolorizing and filtering device of this utility model sprays foreign objects or impurities falling through the nozzle, preventing them from adhering to the inner wall of the hopper. The protective cover prevents foreign objects from falling onto the nozzle and causing blockage. When a large amount of material accumulates in the hopper and causes the nozzle to become blocked, the rotating cover can be rotated in advance to cover the nozzle with the protective cover and the rotating cover, preventing foreign objects from entering the nozzle.

[0003] However, existing technologies have some problems: Currently, conventional activated carbon decolorization involves adding activated carbon into a reaction vessel for decolorization, and then filtering out the activated carbon after decolorization. This process is complex and the reaction vessel is difficult to clean, affecting work efficiency. In addition, among the filtration devices commonly used in factories, the CUNO circulating filtration device uses fixed activated carbon as its packing material, which is irreplaceable and can only be used for decolorization, resulting in a single function and a narrow range of applications. Therefore, we propose a filtration device for large-scale production. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a scale-up filtration device. The feed pipe and discharge pipe connected to the inlet and outlet of the filter press can be disassembled. When activated carbon or silica gel decolorization fails to produce a qualified product in one attempt, the direction of the connecting pipe can be reversed to achieve circulating filtration, ensuring the filtration effect. Furthermore, the filter press is equipped with layers of activated carbon, silica gel, diatomaceous earth, microcrystalline cellulose, quartz sand, and activated alumina balls, etc., and the packing materials are easy to replace. It can perform multiple functions such as decolorization and purification to meet different filtration needs.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0028] like Figures 1 to 4As shown in the figure, the present invention provides a scale-up filtration device, comprising: a first reaction vessel 1, a filter press 2, and a second reaction vessel 3. The first reaction vessel 1 is connected to the filter press 2 via a first discharge pipe 7, and the second reaction vessel 3 is connected to the filter press 2 via a second discharge pipe 13. Activated carbon layers 9 are provided in multiple sets, all of which are disposed inside the filter press 2. Filter paper 10 is provided on the lower surface of the inner wall of the filter press 2. A temperature controller 12 is provided on one side of the filter press 2, and a self-cleaning control panel 17 is provided on the upper surface of the filter press 2.

[0029] Specifically, such as Figures 1 to 4 As shown, the material is poured into the first reactor 1 and, under stirring, enters the filter press 2 through the first discharge pipe 7 at the bottom of the first reactor 1, which increases the discharge speed and effectively reduces material loss. The material enters the filter press 2, passes through the activated carbon layer 9 for decolorization, and then enters the second reactor 3 through the second discharge pipe 13 connected to the bottom of the filter press 2. If the material is qualified, it is discharged; if it is not qualified, the second discharge pipe 13 is disassembled, the direction of the second discharge pipe 13 on the filter press 2 is changed, and the second discharge pipe 13 is connected to the lower end of the second reactor 3. In this way, the material re-enters the filter press 2 through the second discharge pipe 13 at the bottom of the second reactor 3 for secondary decolorization / purification. This cycle is repeated until the material is qualified.

[0030] It is worth noting that the discharge pipes connected to the second set of feed inlets 8 of the filter press 2 are all detachable. If a qualified product cannot be obtained after one decolorization / purification, the direction of the first discharge pipe 7 can be reversed to achieve circulating filtration and ensure the filtration effect. For example, one end of the first discharge pipe 7 can be placed in the first set of feed inlets 4 to achieve single-reactor circulation until a sample is taken inside the first discharge pipe 7. After the product is tested and found to be qualified, it is then loaded into the second reaction vessel 3.

[0031] The activated carbon layer 9 inside the filter press 2 can be filled with various fillers such as activated carbon, silica gel, diatomaceous earth, microcrystalline cellulose, quartz sand, and activated alumina balls. The fillers are replaceable and can be mixed according to usage requirements. In addition, filter paper 10 can be added inside the filter press 2. By adjusting different grades of filter paper 10, the first pass rate can be ensured. It has a wide range of applications and improves the filtration effect.

[0032] It should be noted that when the filter press 2 needs to filter other products quickly, it can be operated using the self-cleaning control panel 17 on the upper part of the filter press 2 to achieve self-cleaning of the internal pipes of the filter press 2. The cleaned filtrate can be discharged through the second discharge pipe 13. The self-cleaning control panel 17 achieves backwashing of the internal pipes by opening the control hydraulic valve and the action of the hydraulic cylinder piston, thereby achieving the effect of convenient cleaning after use.

[0033] Furthermore, a first set of feed inlets 4 are provided on the upper surface of the first reactor 1, a second set of feed inlets 8 are provided on the upper side of one side of the filter press 2, one end of the first discharge pipe 7 is fixedly installed at the lower end of the first reactor 1, and the other end of the first discharge pipe 7 is connected to the second set of feed inlets 8.

[0034] Furthermore, a stirring paddle 5 and a first temperature detector 6 are installed inside the first reaction vessel 1.

[0035] Furthermore, the second reactor 3 has a third set of feed inlets 14 at its upper end, one end of the second discharge pipe 13 is located at the lower end of the other side of the filter press 2, and the other end of the second discharge pipe 13 is located inside the third set of feed inlets 14. The lower end of the second reactor 3 is provided with a discharge valve 15, and the second reactor 3 is provided with a second temperature detector 18.

[0036] Furthermore, the filter press 2 has an opening on one side, and a packing replacement valve 16 is provided at the opening. The packing replacement valve 16 is set in a corresponding manner to the activated carbon layer 9.

[0037] Specifically, such as Figure 4 As shown, when the activated carbon layer 9 needs to be replaced after use, the packing replacement valve 16 can be opened to quickly replace the activated carbon layer 9. This facilitates the replacement of the activated carbon layer 9 and effectively solves the problem of easily replacing the activated carbon layer 9 in the filter device to achieve the desired filtration effect.

[0038] Furthermore, a heat insulation layer 11 is provided on the outer surface of the filter press 2, and the temperature controller 12 is provided in a corresponding manner with the heat insulation layer 11;

[0039] Specifically, such as Figure 4 As shown, the heat insulation layer 11 and temperature controller 12 installed on the outside of the filter press 2 can heat and keep different chemical products warm, realizing the multi-purpose of the filtration device. For example, some chemicals require heat filtration, and different chemical products can be filtered at a certain temperature, thus realizing the multi-purpose of the filtration device.

[0040] Furthermore, multiple sets of filter paper 10 can be provided, and the filter pore radii on the surfaces of the multiple sets of filter paper 10 are different.

[0041] Specifically, such as Figure 4 As shown, before use, the number of filter paper 10 groups can be selected according to the usage situation, and filter paper 10 with different pore sizes can be set at the bottom of the filter press tank 2, thereby achieving the effect of convenient filtration and improved filtration speed.
