Description

Technical Field

[0001] This utility model relates to the field of reactor filtration technology, specifically to a filtration mechanism for a UV resin reactor. Background Technology

[0002] UV resin, also known as photosensitive resin, is a mixture of prepolymers that undergo rapid physical and chemical changes in a short time after being exposed to light. In the production process of UV resin, fluid resin and composite agent are mixed. The resin is heated and softened to form fluid resin. The fluid resin may solidify during transportation. In order to ensure the degree of mixing between fluid resin and composite agent, the solidified resin must be filtered out when the fluid resin is put into the reaction vessel for mixing and reaction.

[0003] A search revealed a utility model patent in China with patent number CN27567688U, which discloses a filtration mechanism for a UV resin reactor. By combining the filter element with a steel frame, it helps prevent the filter element from being deformed by the pressure of the UV resin during use. In addition, the filter element uses a cone-shaped filter screen, which can increase the filtration area of ​​the UV resin and avoid clogging.

[0004] However, in actual use, the above-mentioned device is inconvenient to disassemble the filter element. It requires first removing the screws and nuts, then separating the upper and lower pressure plates to remove the filter element. The disassembly process is complicated and not conducive to quick disassembly. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a filtration mechanism for a UV resin reactor, which effectively solves the problem that existing technologies require disassembling screws and nuts first, then separating the upper and lower pressure plates to remove the filter components, resulting in a complex disassembly process and low disassembly efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a filtration mechanism for a UV resin reactor, including an upper cavity. A second filter bucket is disposed at the bottom of the upper cavity, and a first filter bucket is disposed above the second filter bucket. A limiting component is disposed on the side of the first filter bucket that is attached to the upper cavity. The limiting component includes a connecting block fixedly installed on the first filter bucket. A guide plate is fixedly connected to the end of the connecting block away from the first filter bucket. A movable block is slidably connected to the guide plate. One end of an elastic plate is fixedly installed on the side wall surface of the upper cavity. The other end of the elastic plate is engaged with the movable block. A lower cavity is slidably connected to the upper cavity. The lower cavity is fixedly installed on a base plate, and a discharge port is opened on the surface of the lower cavity.

[0008] Furthermore, the inner wall of the upper cavity is provided with an internal thread, and the outer wall of the second filter bucket is provided with an external thread. The internal thread and the external thread are mutually adapted to each other, and the internal thread and the external thread are threadedly connected.

[0009] Furthermore, the limiting components are provided in two sets, and the two sets of limiting components are symmetrically arranged.

[0010] Furthermore, an installation cavity is provided on the top surface of the upper cavity, a spring is fixedly installed at the bottom of the installation cavity, and a movable block and a connecting block are slidably connected to the installation cavity.

[0011] Furthermore, a sliding groove is formed on the side wall surface of the upper cavity, and the sliding groove is slidably connected to the elastic plate.

[0012] Furthermore, the upper cavity is fixedly equipped with multiple sets of retaining posts, which are arranged in a circumferential array.

[0013] Furthermore, the base plate is fixedly installed with multiple sets of retaining sleeves, which are mutually adapted to the base plate, and the base plate and retaining sleeves are slidably connected.

[0014] Furthermore, a flow cavity is provided between the second filter bucket and the first filter bucket, and the top of the second filter bucket is in a non-accessible state.

[0015] Beneficial effects

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] I. This utility model forms a double-layer filtration structure by setting a second filter bucket at the bottom of the upper cavity and a first filter bucket above it, which effectively improves the filtration effect. At the same time, the limiting component ensures that the position of the first filter bucket is fixed during the filtration process, thereby enhancing the stability of the filtration mechanism. In addition, the limiting component makes it easy and quick to disassemble and install the first filter bucket, which is convenient for users to clean and replace the filter bucket, thus improving the maintainability of the filtration mechanism.

[0018] Second, this utility model, through the flow chamber set between the second filter bucket and the first filter bucket, allows some raw materials to flow directly to the next stage through the holes on the surface of the first filter bucket, while other raw materials enter the flow chamber through the through holes at the bottom of the first filter bucket and then flow out through the holes on the surface of the second filter bucket. This not only reduces the workload of the first filter bucket, but also effectively avoids the problem of decreased filtration efficiency caused by the blockage of the holes on the surface of the first filter bucket, thus improving the overall filtration effect.

[0019] Third, this utility model achieves a detachable connection through the sliding connection of the locking post and the locking sleeve. During disassembly, the upper cavity and the lower cavity separate first, and the locking post and the locking sleeve separate later, which avoids the material in the lower cavity being brought out when the upper cavity is pulled out, thereby preventing environmental pollution and ensuring the safety and environmental protection of the disassembly process.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] A filtration mechanism for a UV resin reactor, see attached figure. Figure 1 - Figure 6 The system includes an upper cavity 1, with a second filter bucket 12 located at the bottom of the upper cavity 1. A first filter bucket 6 is located above the second filter bucket 12. A limiting component is provided on one side of the first filter bucket 6 that is in contact with the upper cavity 1. The limiting component includes a connecting block 14 fixedly installed on the first filter bucket 6. A guide plate 19 is fixedly connected to the end of the connecting block 14 away from the first filter bucket 6. A movable block 18 is slidably connected to the guide plate 19. One end of an elastic plate 7 is fixedly installed on the side wall surface of the upper cavity 1. The other end of the elastic plate 7 is engaged with the movable block 18. The upper cavity 1 is slidably connected to the lower cavity 2, which is fixedly installed on the base plate 3. The surface of the lower cavity 2 is provided with a discharge port 5. Raw materials are added to the upper cavity 1 and filtered by the first filter 6 and the second filter 6. The filtered raw materials enter the lower cavity 2 and are discharged from the discharge port 5. When the first filter 6 needs to be disassembled, the elastic plate 7 is pulled outward to release the locking limit between the elastic plate 7 and the movable block 18, thereby realizing the disassembly of the first filter 6 and facilitating the user to clean the filter 6.

[0031] It is worth noting that the inner wall of the upper cavity 1 is provided with an internal thread 8, and the outer wall of the second filter bucket 12 is provided with an external thread 9. The internal thread 8 and the external thread 9 are mutually compatible and are threadedly connected. When it is necessary to disassemble the second filter bucket 12, the threaded connection between the two can be released by separating the upper cavity 1 from the lower cavity 2 and rotating the second filter bucket 12, which facilitates the user's disassembly of the second filter bucket 12 and improves the disassembly efficiency.

[0032] In the above technical solution, two sets of limiting components are provided, and the two sets of limiting components are symmetrically arranged. An installation cavity 16 is opened on the top surface of the upper cavity 1. A spring 15 is fixedly installed at the bottom of the installation cavity 16. The installation cavity 16 is slidably connected to the movable block 18 and the connecting block 14. A sliding groove 10 is opened on the side wall surface of the upper cavity 1. The sliding groove 10 is slidably connected to the elastic plate 7. When installing the first filter hopper 6, the movable block 18 is aligned with the installation cavity 16 and inserted into the installation cavity 16. When the movable block 18 contacts the elastic plate 7, the elastic plate 7 slides outward in the sliding groove 10. The movable block 18 moves towards the connecting block 14 on the guide plate 19 until the movable block 18... The opposite surfaces of the movable block 18 and the connecting block 14 are completely overlapped, allowing the movable block 18 to pass smoothly through the elastic plate 7. During this process, the elastic plate 7 is deformed by force. When the movable block 18 slides past the elastic plate 7, it moves downward to the bottom of the guide plate 19 due to its own weight, creating a new gap between the movable block 18 and the connecting block 14. This gap is then filled by the elastic plate 7, which has recovered its deformation, thus fixing the first filter hopper 6. During disassembly, since the spring 15 is in a compressed state, when the elastic plate 7 does not limit the movable block 18, the spring 15 recovers its deformation and drives the first filter hopper 6 to move upward, thus popping out the first filter hopper 6 and further improving the disassembly efficiency.

[0033] Furthermore, the upper cavity 1 is fixedly equipped with multiple sets of locking posts 11, which are arranged in a circumferential array. The base plate 3 is fixedly equipped with multiple sets of retaining sleeves 4, which are mutually compatible with the base plate 3 and are slidably connected. When it is necessary to disassemble the upper cavity 1 and the lower cavity 2, the upper cavity 1 is lifted upward to separate the upper cavity 1 and the lower cavity 2. The upper cavity 1 and the lower cavity 2 are separated first, and the locking posts 11 and retaining sleeves 4 are separated later, to avoid the raw materials in the lower cavity 2 being brought out when the upper cavity 1 is pulled out, which would cause environmental pollution.

[0034] In addition, a flow chamber 13 is provided between the second filter hopper 12 and the first filter hopper 6. The top of the second filter hopper 12 is not accessible. Some raw materials flow smoothly to the next stage through the holes on the surface of the first filter hopper 6, while other raw materials flow directly to the flow chamber 13 through the through holes at the bottom of the first filter hopper 6 and then smoothly flow to the next stage through the holes on the surface of the second filter hopper 12. This reduces the workload of the first filter hopper 6 and avoids the decrease in filtration efficiency caused by the blockage of the holes on the surface of the first filter hopper 6.

[0035] Working principle: After the raw material is added to the upper cavity 1, it enters the lower cavity 2 through the double filtration of the first filter bucket 6 and the second filter bucket 12, and is finally discharged from the outlet 5. The first filter bucket 6 is fixed by the snap-fit ​​between the movable block 18 and the elastic plate 7. The first filter bucket 6 is popped out by the recovery of the deformation of the spring 15, which improves the disassembly efficiency. The second filter bucket 12 is disassembled by rotating it to release the thread restriction. At the same time, the upper cavity 1 and the lower cavity 2 are detachably connected by the sliding connection of the locking post 11 and the locking sleeve 4, which facilitates cleaning and maintenance.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
