Description

Technical Field

[0001] The utility model relates to the technical field of sewage filter screens, in particular to a solid matter filter screen device in sewage. Background Technique

[0002] Screen filtration is a pretreatment method for removing large suspended solids and debris in wastewater to protect the normal operation of subsequent treatment facilities. The components of screen filtration include parallel rods, bars, metal meshes, grid meshes or perforated plates. Among them, those composed of parallel rods and bars are called grilles; those composed of wire fabrics or perforated plates are called screens. Among them, the grille removes the relatively large suspended solids that may block the water pump units and pipeline valves; while the screen removes the fine fibers in suspension that are difficult to remove with the grille.

[0003] The traditional solid matter filter screen device in sewage is a screen filter. The sewage is filtered by driving a drum screen through a motor. A scraper is arranged inside the screen filter to scrape the dirt on the surface of the drum screen. The filtered sewage is collected through a water collecting tank.

[0004] Such solid matter filter screen devices in sewage have the following disadvantages: The drum screen is fixedly arranged and cannot be disassembled, which is inconvenient for maintenance and replacement. Moreover, the angle of the scraper is fixed and the flexibility is poor. For this reason, we propose a solid matter filter screen device in sewage. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1-6 , this embodiment provides a technical solution: a solid matter filtering and screening device in sewage, including a filter sieve tank 1;

[0028] Filter sieve tank 1: A water inlet tank 2 is fixedly connected to the upper end of its rear side. A detachable drum sieve 3 is arranged in the middle of the right side wall of the filter sieve tank 1. Rotating shafts 15 are fixedly connected to the front ends of the left and right side walls of the filter sieve tank 1. A chute is provided in the middle of the rotating shaft 15 on the left side. A slider 19 is slidably connected in the chute. Uniformly distributed flat tooth-shaped inserts 20 are arranged at the right end of the slider 19. A rotating block 21 is rotatably connected to the right end of the chute. Uniformly distributed flat tooth-shaped inserts 20 are also arranged at the left end of the rotating block 21. The two flat tooth-shaped inserts 20 are inserted into each other. A pressing column 22 is arranged in the middle of the slider 19. The pressing column 22 passes through a circular hole 1 in the middle of the rotating block 21 and extends to the right side of the rotating shaft 15. A connecting rod 16 is rotatably connected to the outer surface of the rotating block 21 on the left side. A connecting rod 16 is also rotatably connected to the outer surface of the rotating shaft 15 on the right side. A brush 17 is provided on the bottom surface at the rear side between the two connecting rods 16. If it is necessary to adjust the angle of the brush 17, the pressing column 22 can be held. The pressing column 22 will squeeze the slider 19 into the chute under the pressing force. The slider 19 squeezes the spring 18 inward to make it contract. At this time, the two flat tooth-shaped inserts 20 will move away from each other, thus releasing the limit of the brush 17. After adjusting the angle of the brush 17, the pressing column 22 is released. The pressing column 22 loses the downward pressing force and returns to its original position under the action of the spring 18, so that the two flat tooth-shaped inserts 20 are inserted into each other, realizing the angle locking of the brush 17. A spring 18 is arranged between the left side of the slider 19 and the inner wall of the chute. A control switch group 14 is arranged at the upper end of the front side of the filter sieve tank 1. The input end of the control switch group 14 is electrically connected to an external power supply. A socket 23 is rotatably connected to the middle of the right side wall of the filter sieve tank 1. A toothed slot 10 is provided in the socket 23. A connecting shaft 7 is fixedly connected to the middle of the right side of the drum sieve 3. Uniformly distributed toothed inserts 9 are arranged on the outer surface of the connecting shaft 7. The toothed inserts 9 are inserted into the toothed slot 10. If it is necessary to replace the drum sieve 3 with different mesh sizes, the locking bolt 8 can be unscrewed to pull out the connecting shaft 7. Select a suitable drum sieve 3, align the toothed insert 9 at the upper end of the connecting shaft 7 with the toothed slot 10 in the socket 23 and insert it, and then tighten the locking bolt 8. Threaded holes are provided at the right ends of both the connecting shaft 7 and the socket 23. A locking bolt 8 is threadedly connected in the threaded hole. A motor 6 is arranged in the middle of the right side of the filter sieve tank 1. The output shaft of the motor 6 passes through a circular hole 2 on the right side of the filter sieve tank 1 and is fixedly connected to the socket 23. The input end of the motor 6 is electrically connected to the output end of the control switch group 14. A water outlet pipe 5 is arranged in the middle of the left side of the filter sieve tank 1. The right end of the water outlet pipe 5 is fixedly connected to a water inlet tank 4. The water inlet tank 4 is communicated with the water outlet pipe 5. The water inlet tank 4 is located inside the drum sieve 3. The water inlet of the water inlet tank 4 and the water outlet of the water inlet tank 2 are in the same vertical plane. A slag collection tank 13 is arranged at the lower left end of the filter sieve tank 1. The slag collection tank 13 is communicated with the filter sieve tank 1. An electric push rod 11 is arranged at the lower right end of the filter sieve tank 1. The left end of the telescopic end of the electric push rod 11 passes through a circular hole 3 on the right side of the filter sieve tank 1 and is fixedly connected to the right end of a scraper 12. The scraper 12 corresponds to the left and right positions of the slag collection tank 13. The input end of the electric push rod 11 is electrically connected to the output end of the control switch group 14.First, the motor 6 needs to be turned on by controlling the switch group 14. The motor 6 drives the rotary screen 3 to rotate. Then, connect the water outlet pipe 5 to an external water collection tank. After that, sewage can be poured into the water inlet tank 2. The sewage falls on the surface of the rotary screen 3 from the edge of the water inlet tank 2. Then, through the filtration of the rotary screen 3, the solid substances in the sewage fall on the surface of the rotary screen 3. The filtered sewage flows into the water inlet tank 4 inside the rotary screen 3 and then flows into the external water collection tank through the water outlet pipe 5. The solid substances on the surface of the rotary screen 3 will fall to the bottom of the filter screen pool 1 as the rotary screen 3 rotates. Since the bristles of the brush 17 are in contact with the surface of the rotary screen 3, the solid substances that adhere relatively firmly will be brushed off by the brush when the rotary screen 3 rotates to the lower end of the brush 17. At this time, the electric push rod 11 can be turned on by controlling the switch group 14. The electric push rod 11 drives the scraper 12 to push the solid substances at the bottom of the filter screen pool 1 into the slag collection pool 13 for easy treatment. The angle of the brush 17 can be adjusted to adapt to the screening and filtering of solid substances by rotary screens of different diameters. The rotary screen 3 is easy to disassemble, convenient for replacement and maintenance, and has strong flexibility.

[0029] The working principle of a solid substance filter screen device for sewage provided by the present utility model is as follows: When sewage solid substance filtration is required, the sewage solid substance filtration staff need to first turn on the motor 6 by controlling the switch group 14. The motor 6 drives the rotary screen 3 to rotate. Then, connect the water outlet pipe 5 to an external water collection tank. After that, sewage can be poured into the water inlet tank 2. The sewage falls on the surface of the rotary screen 3 from the edge of the water inlet tank 2. Then, through the filtration of the rotary screen 3, the solid substances in the sewage fall on the surface of the rotary screen 3. The filtered sewage flows into the water inlet tank 4 inside the rotary screen 3 and then flows into the external water collection tank through the water outlet pipe 5. The solid substances on the surface of the rotary screen 3 will fall to the bottom of the filter screen pool 1 as the rotary screen 3 rotates. Since the bristles of the brush 17 are in contact with the surface of the rotary screen 3, the solid substances that adhere relatively firmly will be brushed off by the brush when the rotary screen 3 rotates to the lower end of the brush 17. At this time, the electric push rod 11 can be turned on by controlling the switch group 14. The electric push rod 11 drives the scraper 12 to push the solid substances at the bottom of the filter screen pool 1 into the slag collection pool 13 for easy treatment. If a rotary screen 3 with different mesh sizes needs to be replaced, the locking bolt 8 can be unscrewed to pull out the coupling shaft 7. Select a suitable rotary screen 3 and insert the tooth-shaped plug 9 at the upper end of the coupling shaft 7 into the tooth-shaped slot 10 in the socket 23 and then tighten the locking bolt 8. If the diameter of the new rotary screen 3 changes, the angle of the brush 17 needs to be adjusted. The pressing column 22 can be held down. The pressing column 22 will be squeezed into the chute by the pressing force, and the slider 19 will squeeze the spring 18 inward to make it contract. At this time, the two flat tooth-shaped plugs 20 will move away from each other to release the limit of the brush 17. After adjusting the angle of the brush 17, release the pressing column 22. The pressing column 22 loses the downward pressing force and returns to its original position under the action of the spring 18, so that the two flat tooth-shaped plugs 20 are inserted into each other to lock the angle of the brush 17.

[0030] It should be noted that the electric push rod 11 disclosed in the above embodiments may be selected as ZBT, the motor 6 may be selected as 110BYGH1.8, and buttons corresponding to the motor 6 and the electric push rod 11 one by one and controlling their switches are provided on the control switch group 14.

[0031] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
