Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a filtration device for water treatment. Background Technology

[0002] Water is an essential resource for human life. People generate a large amount of domestic wastewater in their daily lives, and industrial and domestic wastewater is also produced during industrial production and other human activities. This wastewater usually contains a certain amount of suspended particles, requiring preliminary filtration to prevent accumulation and blockage of downstream equipment and pipelines, thus affecting production operations. Existing water treatment filtration devices are typically installed in the middle of the sewage pipe, with filter screens added to the device to trap impurities and particles in the wastewater.

[0003] However, existing filtration devices are prone to filter clogging by impurities during use, requiring frequent cleaning or replacement. Furthermore, many filtration devices use bolts and nuts to secure the filter screens, which can become covered in dirt and rust over time, making them difficult to loosen. This often results in cumbersome disassembly of the filter screens, requiring significant time and effort. In addition, some filtration devices are poorly designed, resulting in low filtration efficiency and an inability to effectively remove fine particles from wastewater, thus increasing the burden on subsequent treatment equipment and affecting the overall treatment effect. To address these issues, there is an urgent need for a more rationally designed water treatment filtration device that offers higher filtration efficiency and easier maintenance to improve the efficiency and effectiveness of wastewater treatment. Summary of the Invention

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a filtration device for water treatment, including a filter box 100 and a filtration mechanism 200 movably installed inside the filter box 100. The filtration mechanism 200 is provided with a double-layer filtration component. The primary filtration layer can initially intercept larger suspended particles and impurities, reducing the burden on subsequent filtration stages. The fine filtration layer can further filter smaller particles and suspended solids, improving filtration accuracy.

[0031] Specifically, the filter box 100 has an internal cavity 101. The filter box 100 has an inlet 102 on the left side. The output end of the inlet 102 is connected to a telescopic groove 103. The telescopic groove 103 has a telescopic pipe 104 installed inside. The input end of the telescopic pipe 104 is connected to the output end of the inlet 102. The output end of the telescopic pipe 104 is fixedly installed with a connecting ring 105. A tensioning component 106 is provided on the outside of the connecting ring 105. The filter box 100 has a drain outlet 107 on the right side. The input end of the drain outlet 107 is connected to the cavity 101.

[0032] The filter mechanism 200 is set inside the cavity 101. After the sewage enters through the inlet 102, it can be discharged into the filter mechanism 200 through the telescopic pipe 104. Under the action of the filter mechanism 200, the impurity particles in the sewage can be blocked at the top of the cavity, and the filtered water can be smoothly discharged through the outlet 107.

[0033] Furthermore, the filtration mechanism 200 includes a sealing cover 201 movably installed on the top of the filter box 100. A first connecting plate 202 and a second connecting plate 203 are symmetrically installed on the front and rear sides of the bottom end of the sealing cover 201. The two second connecting plates 203 are fixedly installed on the inner side of the two first connecting plates 202. An installation plate 204 is fixedly installed on the bottom end of the two first connecting plates 202. A small-diameter filter screen 205 is provided at the center of the installation plate 204. A large-diameter filter cartridge 206 is sleeved on the outer side of the two second connecting plates 203. A cover plate 207 is movably connected to the bottom end of the two second connecting plates 203 and the large-diameter filter cartridge 206.

[0034] In the filtration mechanism 200, a first filtration chamber 208 is formed between the large-pore filter cartridge 206 and the cover plate 207. An opening 206a is provided at the top left side of the large-pore filter cartridge 206, and the input ends of the telescopic tube 104 and the connecting ring 105 pass through the opening 206a and extend into the first filtration chamber 208. Therefore, the sewage entering from the inlet 102 can be discharged into the first filtration chamber 208 through the telescopic tube 104. Larger suspended particles and impurities in the sewage will be blocked by the large-pore filter cartridge 206 in the first filtration chamber 208, while the water source will be discharged into the cavity 101 through the filter holes of the large-pore filter cartridge 206. This achieves preliminary filtration, removes large particulate impurities, and reduces the entry of larger particles into subsequent filtration stages, preventing blockage of subsequent filtration equipment and protecting the normal operation of the equipment.

[0035] Furthermore, the outer wall of the mounting plate 204 in the filtration mechanism 200 fits against the inner wall of the cavity 101, forming a sealed structure. Therefore, the mounting plate 204, the small-aperture filter screen 205, and the upper part of the cavity 101 form a second filtration chamber 209. Combined with the preliminary filtration effect described above, the remaining wastewater is directly discharged into the second filtration chamber 209. In the second filtration chamber 209, the small-aperture filter screen 205 further filters the wastewater, removing smaller suspended particles and impurities to ensure that the effluent water quality meets the standards. Finally, after the fine filtration by the small-aperture filter screen 205, the filtered wastewater is discharged to the bottom of the cavity 101 and finally discharged to the outside of the device through the drain outlet 107, ensuring that the entire water treatment process is efficient and smooth, and improving the cleanliness of the effluent and the service life of the equipment.

[0036] In summary, the filtration process of this device is as follows:

[0037] First, wastewater enters through the inlet 102 on the left side of the filter box 100 and is discharged into the first filter chamber 208 of the filter mechanism 200 through the telescopic groove 103 and the telescopic pipe 104. The first filter chamber 208 is formed by a large-pore filter cylinder 206 and a cover plate 207. Larger suspended particles and impurities in the wastewater are blocked by the large-pore filter cylinder 206, achieving preliminary filtration. The water after preliminary filtration is discharged into the cavity 101 through the filter holes of the large-pore filter cylinder 206, reducing the entry of larger particles into subsequent filtration stages, preventing clogging of subsequent filtration equipment, and protecting the normal operation of the equipment.

[0038] Next, the remaining wastewater enters the second filtration chamber 209, which is formed by the mounting plate 204, the small-aperture filter screen 205, and the upper part of the cavity 101. The outer wall of the mounting plate 204 fits against the inner wall of the cavity 101 to form a sealed structure. The small-aperture filter screen 205 further filters the wastewater, removing smaller suspended particles and impurities to ensure that the effluent water quality meets the standards. Finally, after being finely filtered by the small-aperture filter screen 205, the filtered wastewater is discharged to the bottom of the cavity 101 and discharged to the outside of the device through the drain outlet 107 on the right side of the filter box 100. This ensures that the entire water treatment process is efficient and smooth, improving the cleanliness of the effluent and the service life of the equipment.

[0039] Example 2

[0040] Reference Figures 3-9 This is the second embodiment of the present invention. The difference between this embodiment and the previous embodiment is that a quick disassembly and assembly structure is added, which simplifies the disassembly, cleaning and replacement of the filter screen and reduces maintenance costs and operating difficulty.

[0041] Specifically, the mounting plate 204 is fixedly connected to the sealing cover 201 via the first connecting plate 202, while the small-aperture filter screen 205 is installed at the bottom of the mounting plate 204. Therefore, after removing the entire filter mechanism 200 through the handle at the top of the sealing cover 201, it is extremely convenient for staff to clean the small-aperture filter screen 205. The large-aperture filter cartridge 206 is sleeved on the outside of the two second connecting plates 203, and the bottom of the large-aperture filter cartridge 206 is sealed by the cover plate 207 to ensure that the large-aperture filter cartridge 206 will not slide down. Slots 207a are symmetrically installed on the front and rear sides of the top of the cover plate 207, and inserts 203a are fixedly installed at the bottom of the two second connecting plates 203. The inserts 203a are inserted into the slots 207a to ensure a stable connection of the cover plate 207. This design not only prevents the large-aperture filter cartridge 206 from slipping down, but also makes disassembly and cleaning more convenient. When the filter cartridge needs to be cleaned or replaced, the staff can easily remove the cover plate 207 for convenient and quick maintenance.

[0042] Furthermore, a placement groove 101a is provided at the top of the cavity 101, and positioning grooves 101b are symmetrically provided at the front and rear ends of the placement groove 101a. Positioning blocks 201a are symmetrically installed on the front and rear sides of the sealing cover 201, and the sealing cover 201 is placed in the placement groove 101a, and the two positioning blocks 201a are placed in the two positioning grooves 101b. This design allows the operator to accurately place the sealing cover 201 above the cavity 101, so that the opening 206a on the left side of the large-diameter filter cartridge 206 can be effectively aligned with the telescopic tube 104 on the left side, so that the telescopic tube 104 and the connecting ring 105 can smoothly enter the first filter chamber 208 when telescopic.

[0043] It is worth noting that in the above structure, the telescopic tube 104 and the connecting ring 105 are inserted into the first filter chamber 208. Therefore, when the operator needs to remove the entire filter mechanism 200, the operator needs to pull the entire filter structure upward through the handle at the top of the sealing cover 201. At this time, the large-diameter filter cartridge 206 cannot move upward due to the obstruction of the telescopic tube 104 and the connecting ring 105, and thus the filter mechanism 200 cannot be removed. To address this, we designed a tensioning component 106 that can stretch the input ends of the telescopic tube 104 and the connecting ring 105 into the telescopic groove 103, thereby removing the obstruction to the large-diameter filter cartridge 206 and the lower mounting plate 204, ensuring that the filter mechanism 200 can be removed smoothly.

[0044] Specifically, the tensioning assembly 106 includes pull rods 106a symmetrically installed at the front and rear ends of the left side of the connecting ring 105. The left ends of the two pull rods 106a penetrate the inner wall of the cavity 101 and extend to the outside of the filter box 100, where a pull ring 106b is fixedly connected. The outer surfaces of the left ends of the two pull rods 106a are fitted with telescopic springs 106c. The left ends of the two telescopic springs 106c are fixedly connected to the right side wall of the pull ring 106b, and the right ends of the two telescopic springs 106c are fixedly connected to the outer wall of the filter box 100. A limiting plate 108 is fixedly installed at the left end of the filter box 100, below the inlet 102. A slot 108a adapted to the pull ring 106b is provided on the left side of the limiting plate 108.

[0045] When the filter mechanism 200 needs to be removed, the operator first pulls the pull ring 106b installed on the outside of the filter box 100. The pull ring 106b is fixedly connected to the left end of the two pull rods 106a. Pulling the pull ring 106b will cause the pull rods 106a to move to the left. A telescopic spring 106c is sleeved on the outer surface of the left end of the pull rod 106a. When the pull ring 106b is pulled, the telescopic spring 106c will be stretched. The right end of the telescopic spring 106c is fixed to the outer wall of the filter box 100, and the left end is fixedly connected to the right side wall of the pull ring 106b. The function of the stretching spring is to ensure that when the pull ring 106b is pulled, the pull rod 106a can overcome the resistance of the spring and move smoothly. The pull rod 106a passes through the inner wall of the cavity 101 and extends to both ends of the connecting ring 105. Pulling the pull ring 106b will move the pull rod 106a to the left, while simultaneously moving the connecting ring 105. When the telescopic tube 104 retracts to the left into the telescopic groove 103, and the pull rod 106a moves, the connecting ring 105 and the telescopic tube 104 retract into the telescopic groove 103, releasing the obstruction to the large-diameter filter cartridge 206 and the mounting plate 204. In this way, the staff can easily lift and remove the entire filter mechanism 200 by using the handle at the top of the sealing cover 201. The fixation after stretching is achieved by the slot 108a. A limiting plate 108 is fixedly installed at the left end of the filter box 100, below the water inlet 102. The left side of the limiting plate 108 has a slot 108a that matches the pull ring 106b. After the pull ring 106b is pulled into place, it can be locked in the slot 108a to ensure that the pull rod 106a, the connecting ring 105 and the telescopic tube 104 remain in a retracted state and do not spring back during the entire maintenance process. After the card slot 108a fixes the pull ring 106b, it ensures that all components remain stable during maintenance, avoiding operational errors or injuries caused by accidental rebound.
