[0019] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.
[0020] like Figure 1-4 The illustrated high-efficiency and safe filtration device includes a protective cylinder 1. The protective cylinder 1 has support feet 12 at its bottom. The protective cylinder 1 consists of upper and lower sections connected by quick-release clamps 10, making it simple to use, easy to maintain, and highly safe. The protective cylinder 1 is made of metal and provides support and protection for the entire device.
[0021] It also includes a filter cartridge 3 located inside the protective cylinder 1, with end caps 11 welded to the upper and lower ends of the filter cartridge 3. The filter cartridge 3 forms a sealed cavity structure, which can prevent leakage of the filter medium and ensure safety. The filter cartridge 3 is made of high-temperature resistant PFA material. The filter cartridge 3 is a disposable structure. When replacement is needed, the quick-release clamp 10 can be opened directly to replace the entire filter cartridge 3. The whole process is very safe, and no contaminants will be introduced during replacement, and it is not easy to cause chemical spills, ensuring the safety of operators. It is especially safe and reliable for filtering corrosive filter media. The entire device filters pure materials and has good high-temperature resistance.
[0022] The end cap 11 is provided with an inlet / outlet pipe 111 and an exhaust pipe 112, and the protective cylinder 1 is provided with an opening for the inlet / outlet pipe 111 and the exhaust pipe 112 to pass through. Regarding the inlet / outlet pipe 111, the one located above the filter cylinder 3 is the inlet pipe, and the one located below the filter cylinder 3 is the outlet pipe.
[0023] The filter cylinder 3 is provided with three guide plates 31, and several guide holes are evenly distributed on the guide plates 31. The purpose is to divert the upstream liquid as it flows from top to bottom, so that the liquid flow is more uniform and the high-temperature liquid can fill the entire cavity more evenly.
[0024] like Figure 5 As shown, the filter also includes a filter adsorption material 6 filled inside the filter cylinder 3. The filter adsorption material 6 comprises several layers of stacked activated carbon fibers 61, resulting in high filtration efficiency. The shape and size of the activated carbon fibers 61 are the same as the cross-sectional shape and size of the filter cylinder 3, allowing the edges of the activated carbon fibers 61 to adhere to the inner wall of the filter cylinder 3. This avoids wasting activated carbon fiber 61 material while ensuring orderly filling of the filter cylinder 3, thus guaranteeing filtration efficiency. Using activated carbon fibers 61 to fill the filter cylinder 3 also ensures that the filter adsorption material 6 remains stable during transportation and does not shake.
[0025] Activated carbon particles 62 are filled between adjacent activated carbon fibers 61, thus leaving gaps between adjacent activated carbon fibers 61, which does not affect the flow rate of liquid in the filter cylinder 3 and improves the filtration efficiency of activated carbon fibers 61.
[0026] The filter adsorption material is located below the uppermost guide plate 31. It also includes a threaded pressure rod 2, which is inserted into the inlet / outlet pipe 111 at the upper end of the filter cylinder 3 and abuts against the uppermost guide plate 31 to prevent the filter adsorption material from shaking during transportation. The activated carbon fiber 61 adheres to the guide plate 31, preventing activated carbon particles 62 from leaking out from the guide holes on the guide plate 31. In use, the threaded pressure rod 2 is removed, and the liquid inlet is connected to the upstream liquid.
[0027] It also includes a filter 4 located at the bottom of the filter cylinder 3. The filter 4 includes an inner frame 45, an outer frame 43, a filter layer 44 sandwiched between the inner frame 45 and the outer frame 43, and an upper cover 41 and a lower cover 42 welded to the inner frame 45, the outer frame 43, and the filter layer 44. The upper cover 41 covers the inner frame 45, the outer frame 43, and the filter layer 44 to prevent the filter medium from entering the filter 4 from the top. The lower cover 42 is welded to the end cap 11, and the lower cover 42 is provided with a liquid outlet 46, which is connected to the inlet and outlet pipes 111. The function of the filter layer 44 is to prevent the upstream micro-filter adsorption material from flowing into the lower layer, thus playing a secondary interception and purification role.
[0028] The filter medium enters from the outer frame 43, passes through the filter layer 44, and then enters the interior of the filter 4 through the inner frame 45. It flows out from the outlet 46 and enters the next process through the inlet and outlet pipes 111. Together with the filter adsorption materials, multiple interceptions are formed, which can effectively ensure the purity of the filter medium flowing downstream.
[0029] High-temperature liquid enters the filter cylinder 3 through the inlet, is purified by the filter adsorption material, and then flows out through the inlet / outlet pipe 111 after passing through the lower filter 4. The filtration effect is excellent and the filtration is pure. The filter medium is purified by the filter adsorption material and then filtered by the filter, forming multiple interceptions, which can effectively ensure the purity of the filter medium flowing downstream.

All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
