Description

Technical Field

[0001] This utility model relates to the field of chemical equipment and liquid purification technology, specifically a chemical liquid purification device with a detachable filter element. Background Technology

[0002] Chemical liquid purification equipment is a key device used to remove impurities or harmful components from liquids. It is widely used in chemical, pharmaceutical and other fields to improve the purity of liquids through physical or chemical methods, thereby ensuring production safety and product quality.

[0003] A search revealed existing technology (publication number: CN113521805B), which describes "a purification device for ammonia in liquid sodium cyanide." This utility model combines an ammonia removal tower with a purification tower, and uses a heating mechanism to maintain the liquid temperature to improve the ammonia removal efficiency.

[0004] However, while existing technologies have certain advantages in continuous operation and thermal efficiency, they still have some shortcomings: their overall structural design is relatively fixed and no modular filter cartridges have been introduced. This design results in insufficient adaptability of the equipment when processing liquids of different concentrations or compositions. At the same time, the replacement of filter media after saturation or failure is complicated and may affect purification efficiency and the overall service life of the equipment.

[0010] The equipment cover assembly also includes: a snap-fit ​​assembly, the upper half of which is fixed to one side of the cover and the lower half of which is fixed to one side of the purification chamber, for locking the cover; a handle, fixed to the cover, for lifting the cover; a liquid inlet, which is fixed to the cover and is used to deliver the liquid to be purified into the heating element; and a gas outlet, which is fixed to the cover and is used to discharge the gas generated during the purification process.

[0011] As a further description of the above technical solution:

[0012] The filter element assembly also includes: a connecting rod, fixed to the multi-layer filter media, for driving the multi-layer filter media to rotate; and a motor, fixed to the cover, with its output end rotatably connected to the cover and threadedly connected to the connecting rod, for driving the connecting rod to rotate.

[0013] As a further description of the above technical solution:

When processing liquids with special components, a dedicated adsorption filter media module can be replaced, enabling rapid switching of purification solutions. This improves the processing efficiency of complex liquids compared to traditional fixed filter cartridges. The motor-driven rotary filtration design ensures even stress distribution across all parts of the filter cartridge, preventing premature saturation and failure in certain areas, and extending the filter cartridge's lifespan.

[0021] 2. The sliding connection and handle structure shorten the filter media replacement time, and the snap-fit ​​assembly allows for quick opening and closing of the equipment cover, enabling rapid filter element maintenance; the heating element keeps the liquid at the optimal purification temperature, reducing the impact of temperature fluctuations on filter element performance, ensuring long-term stable operation of the equipment, and reducing overall maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0032] like Figures 1 to 5 As shown, this embodiment provides a chemical liquid purification device with a detachable filter element, comprising: a main body assembly including a purification chamber 101 for containing purified liquid; a device cover assembly including a cover 201 disposed on the purification chamber 101 for sealing the purification chamber 101; a filter element assembly including multiple layers of filter media 301 slidably connected inside the purification chamber 101 for filtering the liquid to be purified; a support assembly including a bracket 401 fixedly connected below the purification chamber 101 for supporting the purification chamber 101; and a liquid outlet assembly including a motor 501 disposed below the purification chamber 101.

[0033] In this embodiment, the filter element assembly and the liquid outlet assembly constitute a chemical liquid purification device with a detachable filter element according to this application.

[0034] It should also be noted that this equipment can be used for any chemical liquid that requires purification, and this application does not limit the specific type of chemical liquid.

[0035] Specifically, the main components also include a heating element 102, which is fixed to the inner surface of the purification chamber 101 and is used to heat the purified liquid.

[0036] In this embodiment, after the heating element 102 heats up, it heats the chemical liquid in the purification chamber 101, reduces the viscosity of the liquid, promotes the separation of impurities, optimizes the purification process through heating, and improves the filtration efficiency.

[0037] Specifically, the equipment cover assembly also includes: a snap-fit ​​assembly 202, the upper half of which is fixed to one side of the cover 201 and the lower half of which is fixed to one side of the purification chamber 101, for locking the cover 201; a handle 203, fixed to the cover 201, for lifting the cover 201; a liquid inlet 204, which is fixed to the cover 201, for conveying the liquid to be purified into the heating element 102; and a gas outlet 205, which is fixed to the cover 201, for discharging the gas generated during the purification process.

[0038] In a preferred embodiment, the upper and lower parts of the snap-fit ​​assembly 202 are fixed together by snap-fit, and the cover 201 is locked by the snap-fit ​​assembly 202. The liquid to be purified flows in from the liquid inlet 204, and the gas generated during the purification process is discharged from the gas outlet 205. The handle 203 facilitates the removal and installation of the cover, thereby achieving cavity sealing, liquid input, gas discharge and convenient operation. Example

[0039] Based on Example 1, in order to further improve the purification efficiency, a filter element assembly is arranged in the purification chamber 101;

[0040] Specifically, the filter element assembly also includes: a connecting rod 302, which is fixed to the multi-layer filter medium 301 and is used to drive the multi-layer filter medium 301 to rotate; and a motor 303, which is fixed to the cover 201, with the output end of the motor 303 rotatably connected to the cover 201 and the output end of the motor 303 threadedly connected to the connecting rod 302, for driving the connecting rod 302 to rotate.

[0041] In this embodiment, when the motor rotates, it drives the connecting rod 302 and the multi-layer filter medium 301 to rotate through the threaded connection, so that the liquid is filtered faster under the action of centrifugal force, while preventing impurities from clogging the filter screen. The rotation filtration improves the purification efficiency and reduces filter element clogging.

[0042] Specifically, the threads on the output end of the motor 303 and the connecting rod 302 are opposite to the direction of motor rotation.

[0043] With this configuration, the output end of motor 303 is opposite to the thread direction of connecting rod 302, ensuring a tighter threaded connection during rotation and a stable connection of the filter element during rotation.

[0044] Specifically, the support assembly also includes: a support leg 402, which is fixedly connected to the underside of the bracket 401 to support the bracket 401; a side plate 403, which is fixedly connected to the underside of the bracket 401, and a second motor 501 is fixedly connected to the lower part of the side plate 403 to support the second motor 501.

[0045] In addition, the bracket 401 and the support leg 402 form a stable support structure, and the side plate 403 provides an installation base for the motor 501, ensuring the stable placement of the equipment and supporting the weight of each component. Example

[0046] Based on Example 2, in order to further improve the purification efficiency, a liquid outlet assembly is arranged below the purification chamber 101.

[0047] Specifically, the liquid discharge assembly also includes: a discharge regulating valve 503, which is rotatably connected to the lower part of the purification chamber 101 and is used to discharge the purified liquid in the purification chamber 101; a linkage rod 502, one end of which is fixedly connected to the output end of the motor 501, and the other end is rotatably connected to the purification chamber 101, and the discharge regulating valve 503 is fixedly connected to the linkage rod 502 and is used to control the opening and closing of the discharge regulating valve 503.

[0048] In this embodiment, motor 2 501 drives linkage 502 to rotate, which in turn drives the discharge regulating valve 503 to switch on and off, thereby controlling the liquid discharge flow rate and realizing automated discharge control of the purified liquid.

[0049] In actual use, when the equipment is working: the chemical liquid to be purified is delivered to the purification chamber 101 of the main component through the liquid inlet 204 of the equipment cover assembly; the gas generated during the purification process is discharged through the gas outlet 205; the cover 201 is locked to the main component by the snap-fit ​​assembly 202; and the handle 203 facilitates opening the cover 201; then the motor 303 starts, and its output end, due to the threaded connection with the connecting rod 302 (the thread is opposite to the direction of motor rotation), drives the connecting rod 302, which is fixed with multiple layers of filter media 301, to rotate. The multi-layer filter medium 301 filters the liquid to be purified in the purification chamber 101. At the same time, the heating element 102 can heat the purified liquid to assist in purification. The bracket 401 and support leg 402 of the support component firmly support the main body of the equipment, and the side plate 403 provides installation support for the second motor 501. In the liquid discharge stage: the second motor 501 starts and drives the discharge regulating valve 503 to rotate through the linkage rod 502, opening the liquid discharge channel. The purified liquid is discharged from the purification chamber 101 through the discharge regulating valve 503, realizing the purified output of chemical liquid.

[0050] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
