[0035] Embodiment:

[0036] The application discloses a wastewater treatment filter for edible alcohol production, which comprises a water inlet pipe 10, a first filter part 20 for filtering solid impurities, a flow guide pipe 30, a second filter part 40 and a water outlet pipe 90 which are sequentially connected.

[0037] The second filter part 40 comprises a top plate 410, a box cover 420 and a second filter box 430, the box cover 420 is detachably connected to the top surface of the second filter box 430, the top plate 410 is detachably connected to the top surface of the box cover 420, and the inner cavity of the second filter box 430 is provided with active carbon filter parts 50 near the water inlet end and the water outlet end respectively, wherein a photocatalyst purification system is arranged between the two active carbon filter parts 50, and an electronic ballast group 80 is further arranged in the box cover 420, and the photocatalyst purification system is electrically connected with the electronic ballast group 80.

[0038] It is illustrated that the photocatalyst purification system is mainly composed of photocatalyst materials, which can produce catalytic reaction by exciting photocatalyst materials with light energy, so as to decompose organic pollutants in water. The photocatalyst material is usually titanium dioxide, which can produce strong oxidizing free radicals under ultraviolet light, effectively destroy the chemical bonds of organic matters and convert them into harmless small molecular substances such as carbon dioxide and water. The photocatalyst purification system is electrically connected with the electronic ballast group 80, and the electronic ballast group 80 is responsible for providing stable current to ensure that the photocatalyst material works in the best state.

[0039] It is worth mentioning that the active carbon filter parts 50 are mainly responsible for adsorbing suspended matters and part of organic matters in water. The active carbon has developed pore structure and large specific surface area, and can effectively adsorb impurities in water. Since the active carbon filter parts 50 are arranged in the inner cavity of the second filter box 430 near the water inlet end and the water outlet end, it can be ensured that the wastewater can be fully adsorbed when passing through the second filter box 430.

[0040] Specifically, in actual application, the wastewater first enters the first filter part 20 through the water inlet pipe 10 to remove most of the solid impurities. Then, the wastewater flows into the second filter box 430 through the flow guide pipe 30. In the second filter box 430, the wastewater first passes through the active carbon filter part 50 near the water inlet end to remove part of the organic matters and suspended matters. Then, the wastewater flows through the photocatalyst purification system to further decompose the organic pollutants. Finally, the wastewater passes through the active carbon filter part 50 near the water outlet end to further remove the residual impurities, and is finally discharged through the water outlet pipe 90. The whole filter is designed in consideration of the efficiency and practicability of wastewater treatment, and through the multi-stage filtering and purification system, it is ensured that the treated water quality reaches the discharge standard. Meanwhile, the detachable design of the second filter part 40 facilitates the maintenance and replacement of the filter material, and ensures the long-term stable operation of the equipment.

[0041] It is further worth mentioning that the water inlet pipe 10, the flow guide pipe 30 and the water outlet pipe 90 are all made of corrosion-resistant materials to ensure that the pipes will not affect the filtering effect or cause leakage due to corrosion when treating wastewater containing alcohol and other chemicals. The inlet end of the water inlet pipe 10 is provided with a mesh structure to prevent large-particle solid impurities from entering the filtering system.

[0042] In combination with the drawings Figure 1 - Figure 8 As shown, the activated carbon filtering component 50 includes filter mesh groove plates 510 and activated carbon filter meshes 520. The filter mesh groove plates 510 are provided at least two, one of which is fixedly installed on the bottom surface of the box cover 420, and the other is fixedly installed on the inner bottom surface of the second filtering box 430. The activated carbon filter meshes 520 are clamped in the first grooves provided on the two filter mesh groove plates 510.

[0043] It is explained that the main function of the filter mesh groove plate 510 is to provide a stable base for fixing and supporting the activated carbon filter mesh 520, so as to ensure that it is not easy to move or fall off during use. The design of the groove plate should ensure that an effective seal can be formed between the filter mesh and the groove plate to prevent unfiltered air from flowing. The activated carbon filter mesh 520 is used to remove impurities, odors and harmful substances in the air, and uses the adsorption characteristics of activated carbon to purify the air. The filter mesh is clamped in the first grooves provided on the two filter mesh groove plates 510 to ensure the stability of the filter mesh and the close combination of the filter mesh and the groove plate, so as to avoid air leakage from the side.

[0044] In combination with the drawings Figure 1 - Figure 8As shown, the box cover 420 is provided with a mounting convex surface 480 at the upper end position of the photocatalyst filter component 60 and the lamp tube component 70, and the electronic ballast group 80 is mounted on the top surface of the mounting convex surface 480. The photocatalyst purification system comprises at least two photocatalyst filter components 60 and three lamp tube components 70. The photocatalyst filter components 60 are arranged between the lamp tube components 70 and are mounted inside the second filter box 430. The lamp tube components 70 are electrically connected with the electronic ballast group 80. The photocatalyst filter component 60 comprises photocatalyst groove plates 610 and photocatalyst filter screens 620. The photocatalyst groove plates 610 are arranged in at least two and are respectively mounted on the top surface and the bottom surface of the second filter box 430. The photocatalyst filter screens 620 are clamped in the second grooves of the two photocatalyst groove plates 610. The lamp tube component 70 comprises lamp tube supports 710 and ultraviolet lamp tubes 720. The lamp tube supports 710 are mounted on the top surface of the second filter box 430. The ultraviolet lamp tubes 720 are arranged in at least four. The bottom ends of the ultraviolet lamp tubes 720 are clamped in the third grooves of the lamp tube supports 710. The top ends of the ultraviolet lamp tubes 720 are fixed on the mounting convex surface 480 and are electrically connected with the electronic ballast group 80.

[0045] As explained, the photocatalyst filter component 60 is designed to provide an effective catalytic reaction area. The photocatalyst filter screen 620 is composed of titanium dioxide aluminum-based honeycomb photocatalyst, which can react with ultraviolet light to generate strong oxidizing free radicals. These free radicals can effectively destroy organic pollutants in water and convert them into harmless small molecular substances. The structural design of the photocatalyst filter component 60 ensures that the wastewater can fully contact the photocatalyst material when flowing through, thereby improving the purification efficiency. In the lamp tube component 70, the ultraviolet lamp tubes 720 are the key components, which are responsible for providing ultraviolet light source to excite photocatalyst material to produce catalytic reaction. The number and layout of the ultraviolet lamp tubes 720 are carefully designed to ensure that the entire photocatalyst filter component 60 area can be uniformly irradiated by ultraviolet light. The structural design of the lamp tube support 710 enables stable installation of the lamp tube and facilitates replacement and maintenance.

[0046] In practical application, the filter can effectively treat the wastewater generated in the production process of edible alcohol, remove solid impurities, organic matter and suspended solids in the wastewater, and ensure that the wastewater meets the discharge standard. The design of the multi-stage filtering and purification system combines the advantages of physical filtration and chemical purification, improves the treatment efficiency and water quality, and ensures the stability and reliability of the filter in harsh environments due to the use of corrosion-resistant materials and the mesh structure that prevents debris from blocking.

[0047] In combination with the drawings Figure 1 - Figure 8As shown, the second filter component 40 further comprises second buckles 440, support feet 450, handles 460 and reinforcing rib plates 470, the top plate 410 and the box cover 420 are fixedly connected through a plurality of second buckles 440, the support feet 450 are installed at the bottom corners of the second filter box 430, the reinforcing rib plates 470 are connected to the bottom of the top plate 410, the handles 460 are provided at least four and are respectively arranged on the top surface of the reinforcing rib plates 470 and the side surface of the second filter box 430, and the water outlet pipe 90 is connected to the water outlet end of the second filter box 430.

[0048] It is explained that the second buckles 440 are used to fixedly connect the top plate 410 and the box cover 420, and the box cover 420 and the second filter box 430, to ensure the stability and sealing of the overall structure, prevent leakage, the support feet 450 are arranged at the four corners of the bottom of the second filter box 430, to improve the stability and support of the filter box, avoid tilting or deformation caused by weight or other external forces, at least four handles 460 are designed and distributed on the top surface of the reinforcing rib plates 470 and the side surface of the second filter box 430, to facilitate the user to move and operate, improve the user experience, the reinforcing rib plates 470 are connected to the bottom of the top plate 410, to increase the rigidity and strength of the structure, can bear greater load and prolong the service life of the equipment, the water outlet pipe 90 is connected to the water outlet end of the second filter box 430, to discharge the filtered water, ensure the normal operation of the filtering system.

[0049] In combination with the drawings Figure 1 - Figure 8As shown, the first filter component 20 includes a first filter box 210, a support frame 220, and a first lock 250. The water inlet pipe 10 is connected to the water inlet of the first filter box 210. The support frame 220 is fixedly connected to the bottom surface of the first filter box 210. The inside of the first filter box 210 is sequentially provided from top to bottom with a grid filter 260, a coarse sieve 270, and a fine sieve 280. The grid filter 260 is obliquely arranged. The first filter box 210 is provided with a discharge port corresponding to the oblique tail end of the grid filter 260. A flow baffle 230 is hingedly connected to the outside of the discharge port. The first filter box 210 is further provided with a rectangular plate 240 corresponding to the flow baffle 230. The open end of the flow baffle 230 is fixed to the end surface of the rectangular plate 240 through the first lock 250. One end of the flow guide pipe 30 is connected to the bottom surface of the first filter box 210, and the other end of the flow guide pipe 30 is connected to the water inlet of the second filter box 430. The grid filter 260 includes a grid filter plate 2610 and at least four flow slowing plates 2630, which are obliquely and fixedly installed on the grid filter plate 2610. First and second through holes 2620 and 2640 are respectively formed in the grid filter plate 2610 and the flow slowing plates 2630.

[0050] As an illustration, the inside of the first filter box 210 is sequentially provided from top to bottom with the grid filter 260, the coarse sieve 270, and the fine sieve 280. The coarse sieve 270 and the fine sieve 280 also use screens with different hole diameters to achieve a more refined filtering effect. In actual work, wastewater first enters the first filter box 210 through the water inlet pipe 10, and larger impurities are intercepted at the grid filter 260. Subsequently, the wastewater is further filtered through the coarse sieve 270 and the fine sieve 280. In the first filter box 210, the grid filter 260 is obliquely arranged, and the impurities in the wastewater gradually deposit near the discharge port at the oblique tail end along the direction of the water flow. By periodically opening the flow baffle 230 and the rectangular plate 240, these impurities can be easily cleaned. The wastewater treated by the first filter box 210 flows into the second filter box 430 through the flow guide pipe 30, where it is subjected to more refined filtering treatment. The grid filter 260 and the sieve of the second filter box 430 further intercept the remaining impurities, ensuring that the wastewater meets the discharge standard. Finally, the wastewater treated by the two filtering processes is discharged through the water outlet of the second filter box 430 and can be safely discharged or used for other production processes.

[0051] In conjunction with the drawings Figure 1 - Figure 8As shown, the coarse screen 270 includes a coarse screen mesh 2710, and the fine screen 280 includes a fine screen mesh 2810, and the third through hole 2720 and the fourth through hole 2820 are respectively arranged on the coarse screen mesh 2710 and the fine screen mesh 2810, and the third through hole 2720 has a larger aperture than the fourth through hole 2820.

[0052] It is explained that the coarse screen 270 includes a coarse screen mesh 2710, which is mainly used for preliminary screening of larger particle materials, and the fine screen 280 includes a fine screen mesh 2810, which is responsible for screening smaller particle materials, and the third through hole 2720 is located on the coarse screen mesh 2710, and the aperture is larger than that of the fine screen mesh 2810. This means that the through hole of the coarse screen mesh 2710 can allow larger particle materials to pass through, while providing a certain blocking effect on smaller particle materials, and the fourth through hole 2820 is located on the fine screen mesh 2810, and the aperture is smaller, which is used to pass smaller particle materials, while preventing larger particles from passing. This design can ensure that the materials can be effectively classified in different screening stages.

[0053] Specifically, during the material screening process, the larger particle materials are blocked by the coarse screen 270 (coarse screen mesh 2710), and the smaller particle materials pass through the third through hole 2720 into the fine screen 280 (fine screen mesh 2810), and then, in the fine screen 280, the smaller particle materials are further screened. Only the materials meeting the aperture standard of the fine screen mesh 2810 can pass through the fourth through hole 2820. Through the combination of screens with different apertures, efficient and accurate material separation can be achieved, and the staff can also flexibly adjust the aperture of the coarse screen 270 and the fine screen 280 according to different actual screening requirements, so as to meet the screening requirements of different particle materials.

[0054] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
