[0042] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] like Figures 1 to 2 As shown, an easily replaceable filtration system connected to a shielded pump includes:

[0045] The inlet end of the shielded pump 1 is connected to the outlet end of the filter 2;

[0046] The gas inlet 21 of filter 2 is connected to the gas injection assembly 3, and the material inlet 22 of filter 2 is connected to the material supply assembly 4; the gas from the gas injection assembly 3 can squeeze out the waste liquid of the material passing through filter 2; both the gas inlet 21 and the material inlet 22 are detachably connected to pipes 5.

[0047] This invention avoids damage to the shielded pump 1 caused by impurities in the material by installing a filter 2 at the shielded pump 1. In addition, this invention connects a gas injection assembly to the gas inlet end of the filter, and uses gas pressure to squeeze the waste liquid out of the filter, thereby achieving efficient waste liquid removal, reducing manual operation and improving processing efficiency.

[0048] In a preferred embodiment, such as Figure 1As shown, filter 2 includes a flange 25 and a filter element mounting structure 26; flange 25 is fixed to the top of filter element mounting structure 26. The filter element mounting structure 26 is the core part of the filter, used to house the filter element and achieve the filtration function. Flange 25 is a disc-shaped part commonly used to connect different components; its edge has bolt holes for fastening two flanges together with bolts, thereby achieving connection and sealing between the two components. Here, flange 25, as a component of filter 2, is fixed to the top of filter element mounting structure 26 to achieve a sealing effect.

[0049] In a preferred embodiment, such as Figure 1 and 2 As shown, the top of the flange 25 is provided with a gas inlet end 21, and the bottom of the filter element mounting structure 26 is provided with a waste liquid outlet 24. The gas inlet end 21 is located at the top of the flange 25, meaning that gas can directly enter the interior of the filter 2 from the flange 25. This design allows the gas injection assembly to be easily connected to the flange 25, thereby introducing gas into the filter. The gas is preferably nitrogen, which helps to drive liquid flow, clean the filter element, or discharge waste liquid.

[0050] In a preferred embodiment, such as Figure 2 As shown, the waste liquid outlet 24 is located at the bottom of the filter element arrangement structure 26, which allows the waste liquid to be discharged directly from the filter. This design helps ensure that the waste liquid flows out smoothly during the filtration process and avoids accumulation inside the filter 2.

[0051] In a preferred embodiment, such as Figure 2 As shown, the filter cartridge arrangement structure 26 includes a housing 261 and a filter cartridge 262; the filter cartridge 262 is housed within the housing 261, and the filter cartridge 262 contains the filter element. The housing 261 is the external protective structure of the filter cartridge arrangement structure, typically made of a robust and durable material, such as metal or plastic, to protect the internal filter cartridge 262 and filter element from damage. Additionally, the housing 261 provides a sealed environment, ensuring that liquids or gases during the filtration process do not leak into the surrounding environment. The filter cartridge 262 is the container for the filter element, typically made of perforated metal, plastic, or other materials to support the filter element and allow liquids or gases to pass through. The filter cartridge 262 is located inside the housing 261, and its design allows for the installation, replacement, and maintenance of the filter element.

[0052] In a preferred embodiment, such as Figure 2 As shown, the filter cartridge 262 includes a cover 262a and a cylindrical structure 262b; one side of the upper end of the cylindrical structure 262b is higher than the other side to form an inclined opening 262c; the cover 262a is inclinedly disposed on the cylindrical structure 262b and matches the inclined opening 262c.

[0053] In a preferred embodiment, such asFigure 2 As shown, the filter cartridge 262 has a material inlet end 22 and a material outlet end 23 on both sides. This inclined design can optimize the flow path of liquids or gases and reduce flow resistance.

[0054] In a preferred embodiment, such as Figure 2 As shown, both the cover 262a and the cylindrical structure 262b are provided with evenly distributed through holes 262c.

[0055] In a preferred embodiment, such as Figure 1 As shown, a vent port 51 is provided on one side of pipe 5. This vent port 51 is specifically designed to detect the gas or liquid state inside pipe 5. This vent port 51 can be used for pressure testing, leak detection, gas composition analysis, and other operations. Such a design is common in industrial piping systems to ensure the safe and efficient operation of the system.

[0056] In a preferred embodiment, such as Figure 1 As shown, the output end of the canned motor pump 1 is connected to an output pipe 11, and the output end of the output pipe 11 is connected to two material output pipes 111. The output of the canned motor pump 1 can be distributed to two different material output pipes through a branch pipe (T-type or Y-type connector). This configuration allows the pump to deliver materials to two different systems or containers simultaneously.

[0057] In a preferred embodiment, such as Figure 1 As shown, a pressure gauge 111 is installed on the output pipeline 11. The pressure gauge 111 can display the pump outlet pressure in real time, helping operators to determine whether the pump is working properly.

[0058] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described utility model concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
