[0002] In chemical production processes, reaction vessels are one of the core pieces of equipment for carrying out chemical reactions. However, traditional reaction vessels often face problems such as incomplete filtration and easy clogging when processing raw materials containing impurities. These problems not only affect the purity and quality of the product, but may also lead to a decrease in equipment operating efficiency and an increase in maintenance costs.

[0003] A search revealed existing technology (publication number: CN220590004U), which describes "a chemical reaction vessel with filtration function." This utility model uses an activated carbon adsorption plate and a water pump circulation system installed inside the shell to filter and purify the liquid in the reaction vessel after it is transported through pipelines, thereby removing impurities and improving the purity of the liquid.

[0004] However, in the existing technology, it is inconvenient to replace the components, and the activated carbon adsorption plate and the placement plate need to be replaced after long-term use. Utility Model Content

[0033] Example 1:

[0034] like Figures 1 to 6 As shown, this embodiment provides a chemical reactor with a multi-layer filtration structure, including: a reactor 1, with a discharge valve 12 at the bottom of the reactor 1; a lid 2, which is opened and closed at the top of the reactor 1; a stirring assembly 3, which is disposed at the top of the lid 2 and whose bottom is located inside the reactor 1; and a filtration module 4, which is disposed on one side of the top of the lid 2.

[0035] In this embodiment, the stirring assembly 3 and the filtration module 4 constitute a chemical reactor with a multi-layer filtration structure as described in this application.

[0036] It should also be understood that the drive motor 31 is common knowledge in the field, and it is only used without modification, so the control method and circuit connection will not be described in detail.

[0037] It should be noted that the cover 2 is sealed to the reactor 1 through the flange 21 and locking bolts 22, the filter screen 23 performs preliminary filtration, the stirring component 3 stirs the material, and the filtration module 4 performs multi-layer filtration of the material to realize the reaction and filtration of chemical materials.

[0038] In addition, in this embodiment, the user first connects the feed pipe 41 to the feed port 42 through flange bolts, then adds the material into the filter element 43 inside the feed port 42 for primary filtration, and then the material enters the filter element 43 inside the reactor 1 for further fine filtration. Then, it is spirally discharged to the bottom of the reactor 1 through the filter screen 23. At the same time, the drive motor 31 is started, and the rotating shaft 32 drives the stirring blade 34 to rotate and stir the material. After stirring is completed, the bottom discharge valve 12 is opened to discharge the material.

[0039] Specifically, the stirring assembly 3 includes: a drive motor 31, which is located at the top center of the cover 2; a rotating shaft 32, which passes through the center of the cover 2 and rotates inside the reactor 1, and whose top is keyed to the output end of the drive motor 31; a spiral channel 33, which is located inside the reactor 1 and on the rotating shaft 32; and stirring blades 34, which rotate inside the reactor 1 and are bolted to the bottom of the rotating shaft 32 for stirring chemical materials.

[0040] In a preferred embodiment, the drive motor 31 drives the rotating shaft 32 to rotate, the spiral channel 33 guides the material flow, and the stirring blades 34 stir the material to ensure that the material is fully mixed and reacted.

[0041] Example 2:

[0042] Based on Example 1, when it is necessary to clean or replace the filter screen 23 and filter element 43, the user can press the two sets of connecting blocks 445 towards the middle. The connecting blocks 445 will drive the two side locking blocks 442 to slide towards the middle inside the filter element 43. The spring 444 is compressed until the end of the locking block 442 away from the spring 444 is released from the locking groove 443. The filter element 43 can then be pulled out for cleaning or replacement. Then, by rotating the four sets of locking bolts 22, the connection between the top of the reactor 1 and the flange 21 is released. Then, the cover 2 is opened upwards to clean or replace the filter screen 23.

[0043] Specifically, the cover 2 includes: a flange 21, which is located at the top of the reactor 1 and at the bottom of the cover 2; four sets of locking bolts 22, which are threaded to the four corners of the flange 21; and a filter screen 23, which is located at the top inside the reactor 1 and at the bottom of the cover 2.

[0044] In this embodiment, flange 21 and locking bolt 22 fix cover 2, and a sealing ring is provided inside. Filter screen 23 filters materials, seals reaction vessel 1 and performs filtration.

[0045] Specifically, the filter module 4 includes: a feed pipe 41, which is located on one side of the top of the mixing assembly 3; a filling port 42, which is located on one side of the top of the mixing assembly 3 and is bolted to the flange of the feed pipe 41; a filter element 43, which is located inside the filling port 42; and a disassembly assembly 44, which has two types and is located on both sides of the top of the filter element 43.

[0046] In this embodiment, the material enters the inlet 42 through the feed pipe 41, the filter element 43 filters the material, and the disassembly assembly 44 facilitates the disassembly of the filter element 43 to perform fine filtration of the material, which is convenient for the maintenance and replacement of the filter element 43.

[0047] Specifically, the disassembly assembly 44 includes: a pinching groove 441, which is formed on both sides of the top of the filter element 43; four sets of snap-fit ​​blocks 442, which slide telescopically on both sides of the top of the filter element 43; four sets of snap-fit ​​grooves 443, which are formed on both sides of the top of the filling port 42; four sets of springs 444, which are located inside both sides of the top of the filter element 43, with one end abutting against the snap-fit ​​block 442; and a connecting block 445, which slides inside the pinching grooves 441 on both sides of the top of the filter element 43, and whose two ends are connected to the two sets of snap-fit ​​blocks 442.

[0048] With this configuration, by pinching the connecting block 445, the elastic force of the spring 444 is overcome, causing the locking block 442 to retract into the filter element 43, thus allowing the filter element 43 to be removed. This makes it easy and quick to remove the filter element 43, facilitating replacement and cleaning.

[0049] In actual use, the user first connects the feed pipe 41 to the inlet 42 via flange bolts. Then, the material is added to the filter element 43 inside the inlet 42 for primary filtration. Afterward, the material enters the reactor 1 and is further finely filtered by the filter element 43. It then spirals through the filter screen 23 to the bottom of the reactor 1. Simultaneously, the drive motor 31 is started, and the rotating shaft 32 drives the stirring blades 34 to rotate and stir the material. After stirring, the bottom discharge valve 12 is opened to discharge the material. When it is necessary to clean or replace the filter screen 23 and filter element 43, the user can press the two sets of connecting blocks 445 towards the center. The connecting blocks 445 will cause the two side locking blocks 442 to slide towards the center inside the filter element 43, compressing the spring 444 until the end of the locking block 442 away from the spring 444 is released from the locking groove 443. The filter element 43 can then be pulled out for cleaning or replacement. Next, the connection between the top of the reactor 1 and the flange 21 is released by rotating the four sets of locking bolts 22. Then, the cover 2 is opened upwards to clean or replace the filter screen 23.

[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.
