Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment filter press. Background Art

[0002] When treating the sewage in the urban sewer, after the sewage flowing into the sewage treatment plant is treated by various systems in the plant, the sewage is purified and flows out from the polluted water quality to the clean water quality. A plate and frame filter press is usually used in sewage treatment. This device filters multiple sewage at multiple levels through the coincidence and counterpressure of multiple groups of water filtration, and at the same time, it is convenient to press the sludge into a mold for collection. However, in the actual treatment process, the pressed mud cake is inside the pressing component, which causes the blockage of the pressing component.

[0003] For the existing filter press, after the sewage is pressed and filtered, compared with the mud cake sticking to the filter plate frame, if the mud cake sticking to the filter cloth is not cleaned in time, the weight of the filtering equipment will increase, resulting in incomplete filtering. When the mud cake on the filter cloth does not fall off completely, and at the same time, because the filter cloth mesh holes are small and single, when multiple groups of filter cloths are arranged in an overlapping manner, it is extremely easy to affect the subsequent sewage transmission and filtration rate due to the blockage of a single group of filter cloths, thereby reducing the sewage treatment effect. Therefore, a sewage treatment filter press is proposed. Summary of the Utility Model

[0011] As a preferred technical solution of the present utility model, the stirring rod and the water level sensor are electrically connected through the second driving motor.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. For this sewage treatment filter, through the use of a static box at the top for primary filtration, larger objects cannot enter the interior of the filtering component, preventing the jamming of internal components caused by the inability to clean larger objects. A rotary filter disk is used in the filter box for segmented filtration, and the filter meshes in each segment of the filter disk are arranged in an array from large to small, effectively improving the filtration effect and preventing the omission of fine impurities. The rotary disk is conducive to shaking off the impurities attached to the filter disk.

[0014] 2. The sewage treatment filter effectively assists the filter screen in filtering by setting a central cylinder in the filter disc and opening filter holes on the outer wall of the central cylinder. The motor on the outer wall of the central cylinder drives the central cylinder, causing the turntable to rotate, which increases the working efficiency of the filter disc. At this time, when the water to be filtered flows out from the water outlet, the drive motor drives the central cylinder again, causing the side connecting rod to rotate along the cylinder wall. At this time, the rotating roller drives the vibration ring to rotate, causing the vibration ring to effectively strike the filter disc, making the dirt adsorbed on the filter screen fall into the barrel. The cleaning scraper on the other side of the connecting rod cleans along the cylinder wall, and the dirt to be cleaned enters the internal collection box of the scraper under force. Since the collection box is slidably connected to the scraper, it is more convenient to disassemble and remove the dirt during later cleaning, effectively avoiding the replacement of large components of the equipment due to the difficulty of disassembly and cleaning, improving the efficiency. The vibration ring set on the side effectively replaces the backwashing equipment, saving the water consumption cost.

[0015] 3. The sewage treatment filter also increases a purification component. There is a water level sensor inside the component. After the filtered sewage enters the inside of the box body, through the operation of the water level sensor, the medicine box on the inner wall of the chute controls the dosage according to the water level. The medicine is scattered into the box from the outlet, and the stirring component starts to mix and stir, making the filtered water become pure water, effectively saving costs and resources.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-6 , a sewage treatment filter, including a static box 1. A plurality of inclined plates 2 are provided on the inner wall of the static box 1. The plurality of inclined plates 2 are symmetrically distributed on the inner wall of the static box 1. A first water outlet 3 is provided on the outer wall of the static box 1. A first guide pipe 4 is provided on the inner wall of the first water outlet 3. A first water inlet 5 is provided on the outer wall of the first guide pipe 4. A filtration component 6 is provided at the bottom of the static box 1. The filtration component 6 includes a second water inlet 61 located at the bottom of the static box 1. A filtration box 62 is provided on the outer wall of the second water inlet 61. A plurality of filtration turntables 63 are provided on the inner wall of the filtration box 62. A plurality of filter screens 64 are provided on the surfaces of the plurality of filtration turntables 63. A central cylinder 65 is provided on the inner wall of the filtration turntable 63. A first drive motor 69 is provided on the outer wall of the central cylinder 65. A connecting rod 610 is provided on the outer wall of the first drive motor 69. A cleaning scraper 66 is provided on the outer wall of the connecting rod 610. A rotating roller 67 is provided on the outer wall of the connecting rod 610 on the side far from the cleaning scraper 66. A plurality of vibration rings 68 are provided on the outer wall of the rotating roller 67. Among them, the static box 1 is set at the top for primary filtration without removing large particulate matter in advance. When larger objects enter the interior of the filtration component, it not only increases the complexity and cost of the treatment process, but also causes internal component jams due to the inability to clean the larger objects, reducing the operating efficiency.

[0025] Please refer to Figure 3, the outer wall of the central cylinder 65 is provided with filtering holes 611. The central cylinder 65 is rotatably connected to the first driving motor 69 through a connecting rod 610. Among them, the arrangement of the filtering holes 611 effectively assists the segmented filtering of the turntable, greatly increasing the working efficiency. When the first driving motor 69 drives the connecting rod 610 to rotate, the central cylinder 65 rotates accordingly, effectively enhancing the filtering efficiency.

[0026] Please refer to Figure 4 , the bottom of the cleaning scraper 66 is provided with a groove 612. The inner wall of the cleaning scraper 66 is provided with a collection box 614. The top of the collection box 614 is fixedly connected with a limit lug 613. The bottom of the collection box 614 is provided with a baffle 615. The collection box 614 is slidably connected to the cleaning scraper 66 through the limit lug 613. Among them, the limit lug 613 arranged at the top of the collection box 614 enables the collection box 614 to be slidably connected to the cleaning scraper 66. After the equipment is cleaned, it is convenient to disassemble, saving time and increasing efficiency, eliminating complex procedures. The baffle 615 arranged at the bottom effectively prevents the dirt cleaned into the collection box from falling due to the angle problem when the scraper rotates.

[0027] Please refer to Figure 2 , the outer wall of the filtering component 6 is provided with a first water inlet 5. The outer wall of the first water inlet 5 is fixedly connected with a second guiding pipe 51. The outer wall of the second guiding pipe 51 is fixedly connected with a second water inlet 61. Among them, the connection of the second guiding pipe 51 to the second water inlet 61 enables the standing water to flow into the interior of the filtering component through the conduit for filtration.

[0028] Please refer to Figure 6 , the outer wall of the filtering component 6 is fixedly connected with a second water outlet 7. A purification component 8 is arranged on the outer wall of the second water outlet 7. The purification component 8 includes a water purification tank 81 located on the outer wall of the second water outlet 7. A second driving motor 82 is arranged on the outer wall of the water purification tank 81. A sliding groove 83 is arranged on the inner wall of the water purification tank 81. A medicine tank 84 is arranged on the outer wall of the sliding groove 83. A telescopic rod 85 is arranged on the outer wall of the medicine tank 84. A stirring rod 86 is arranged on the outer wall of the telescopic rod 85. A discharge port 87 is arranged on the outer wall of the stirring rod 86. A water level sensor 88 is arranged on the inner wall of the water purification tank 81. Among them, by arranging the water level sensor 88 on the inner wall, after the filtered sewage flows into the interior of the purification tank, through the operation of the water level sensor 88, the dosage of the medicine tank 84 can be effectively controlled. After an appropriate amount of medicine is discharged from the outlet, it is mixed by the stirring rod 86.

[0029] Please refer to Figure 4 , the cleaning scraper 66 and the vibration ring 68 are electrically connected through the connecting rod 610 and the first driving motor 69. Among them, driven by the first driving motor 69, the dirt falling off due to the vibration of the vibration ring 68 is directly cleaned by the cleaning scraper 66 at the other end, effectively improving the cleaning efficiency.

[0030] Please refer to Figure 4 , multiple vibration rings 68 are rotatably connected between the rotating roller 67 and the connecting rod 610. Among them, by rotating, the vibration rings 68 vibrate the filter disc in all directions, greatly reducing the dirt residue on the filter screen.

[0031] Please refer to Figure 6 , the stirring rod 86 is electrically connected to the water level sensor 88 through the second driving motor 82. Among them, the electrical connection of the second driving motor 82 can appropriately mix the sprayed chemicals, without wasting costs and effectively saving resources.

[0032] Working principle: When the device needs to be used, due to the setting of the inclined plate 2 in the top static box 1, larger impurities sink to the bottom of the static box 1. At this time, the initially filtered sewage enters the inside of the filter assembly 6 through the first guide pipe 4, and the first driving motor 69 starts to operate, driving the rotation of the central pipe 65. The central pipe drives the central cylinder 65 to rotate. Due to the setting of the segmented filter screen 64, for some extremely fine particulate matter in the sewage, especially the tiny particles close to or smaller than the pore size of the filter medium, the removal effect of an ordinary rotary filter may not be ideal. These fine particles may pass through the filter medium, resulting in the effluent water quality not fully meeting the higher standard requirements. By arranging each section of the filter screen 64 from large to small in sequence, the sewage can be effectively filtered, improving the filtration efficiency and avoiding the appearance of tiny particles. When the filtered sewage is discharged into the cleaning assembly 8, through the operation of the water level sensor 88, the chemical agent tank 84 controls the chemical agent spraying amount through the water level sensor 88, effectively saving resources. After the chemicals are sprayed from the discharge port 87, the stirring rod 86 starts to stir and mix. When cleaning is required, the first driving motor 69 starts to operate. Through the rotation of the connecting rod 610, the cleaning assemblies at both ends are driven to operate. The vibration ring 68 rotates on the rotating roller 67, enabling the 68 to vibrate the turntable more comprehensively. The dirt that falls off after vibration is cleaned by the cleaning scraper 66 at the other end. Pulling out the collection box 614 discharges the dirt out of the mechanism.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
