[0002] A wastewater treatment bar screen, usually referring to a wastewater bar screen or bar screen wastewater machinery, is a device specifically designed for water treatment, especially widely used in the field of urban wastewater treatment. A wastewater bar screen, also known as a bar screen wastewater machinery, is a special water treatment device that can continuously and automatically intercept and remove various shapes of debris from fluids.

[0003] A search revealed that utility model patent CN221287027U discloses a bar screen for sewage treatment. While this utility model patent solves the problem in the prior art where suspended solids cannot be collected and discharged in a timely manner, leading to blockage of the guide plate and backflow of waste, it has the following drawbacks:

[0004] 1. Due to the varying volumes of waste in sewage, different grid densities are required for different usage needs. The grid screen specifications of this utility model patent are fixed, making it inconvenient to adjust according to actual needs, which causes inconvenience during use.

[0005] Second, this utility model patent involves collecting garbage from the grating screen by pouring it into a garbage bin. When the garbage bin is full, it needs to be manually emptied by staff, which takes time. Furthermore, when the temperature is high, the damp garbage is prone to producing odors, causing environmental pollution.

[0006] Therefore, a bar screen for sewage treatment is proposed. Utility Model Content

[0007] In view of this, the present invention provides a bar screen for sewage treatment to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0008] The technical solution of this utility model is implemented as follows: A bar screen for sewage treatment includes a sewage tank. A support frame is fixedly connected to the outer wall of the sewage tank. A motor is fixedly connected to the inner side of the support frame. A support rod is fixedly connected to the output end of the motor. A gear is symmetrically fixedly connected to the outer wall of the support rod. A second support rod is rotatably connected to the inner wall of the sewage tank. A second gear is symmetrically fixedly connected to the outer wall of the second support rod. Both the second and first gears are meshed with chains. A bar screen is fixedly connected between the two sets of chains. Rake teeth are uniformly fixedly connected to one side of the bar screen. A T-shaped groove is opened inside the bar screen. A T-shaped slider is slidably connected to the inner wall of the T-shaped groove. A rotating seat is rotatably connected to one end of the T-shaped slider. A threaded rod is fixedly connected to one side of the rotating seat. The threaded rod is threadedly connected to the bar screen. Rake teeth are uniformly fixedly connected to the upper surface of the T-shaped slider.

[0009] In a further preferred embodiment, a support plate is fixedly connected to the top of the sewage tank, a cleaning net is fixedly connected to the upper surface of the support plate, a feeding hopper is provided at the bottom of the cleaning net, a storage box is connected to the bottom of the feeding hopper, the storage box is fixedly connected to the sewage tank, a second support frame is fixedly connected to the outer wall of the storage box, a second motor is fixedly connected to the inner side of the second support frame, a spiral blade is fixedly connected to the output end of the second motor, and a discharge port is opened on one side of the storage box.

[0010] More preferably, the bottom of the storage box is provided with a drainage outlet 1, the bottom of the storage box is fixedly connected with a water collection plate, the water collection plate is inclined towards the sewage tank, and the outer wall of the sewage tank is provided with a drainage outlet 2 on the side close to the water collection plate.

[0011] More preferably, the cleaning net is tilted toward the feed hopper.

[0012] More preferably, the grating is provided in multiple sets, and the multiple sets of grating are evenly distributed on one side of the chain.

[0013] More preferably, a handle is fixedly connected to the end of the threaded rod away from the rotating seat.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model adds a second rake tooth structure to a bar screen for sewage treatment to achieve the function of adjusting the spacing between the rake teeth. That is, the operator manually turns the handle, which drives the threaded rod to rotate, and the T-shaped slider moves, thereby adjusting the position of the second rake tooth. This allows for adjustment of the spacing between the rake teeth group composed of the first and second rake teeth, making it easy to adjust according to actual needs and convenient to use.

[0016] Second, when this utility model is used in a bar screen for sewage treatment, when the rake teeth one and two move to the cleaning screen, the staggered chain pushes the garbage off. The water in the garbage returns to the sewage tank through the cooperation of drain outlet one, water collection plate and drain outlet two, which prevents the damp garbage from producing odors and causing environmental pollution when the temperature is high. When the storage box is full of garbage, motor two drives the spiral blade to rotate and push the garbage out through the discharge port. There is no need for manual cleaning by the staff, and the cleaning process is relatively fast.

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, this utility model embodiment provides a bar screen for sewage treatment: including a sewage tank 1, a support frame 2 fixedly connected to the outer wall of the sewage tank 1, a motor 3 fixedly connected to the inner side of the support frame 2, a support rod 4 fixedly connected to the output end of the motor 3, gears 5 symmetrically fixedly connected to the outer wall of the support rod 4, a second support rod 6 rotatably connected to the inner wall of the sewage tank 1, gears 7 symmetrically fixedly connected to the outer wall of the second support rod 6, chains 8 meshing with the outer walls of both gears 7 and gears 5, a bar screen 9 fixedly connected between the two sets of chains 8, rake teeth 10 uniformly fixedly connected to one side of the bar screen 9, a T-shaped groove 11 opened inside the bar screen 9, a T-shaped slider 12 slidably connected to the inner wall of the T-shaped groove 11, a rotating seat 13 rotatably connected to one end of the T-shaped slider 12, a threaded rod 14 fixedly connected to one side of the rotating seat 13, the threaded rod 14 being threadedly connected to the bar screen 9, and rake teeth 16 uniformly fixedly connected to the upper surface of the T-shaped slider 12.

[0027] In one embodiment, a support plate 17 is fixedly connected to the top of the sewage tank 1. A cleaning net 18 is fixedly connected to the upper surface of the support plate 17. A feed hopper 19 is provided at the bottom of the cleaning net 18. A storage box 20 is connected to the bottom of the feed hopper 19. The storage box 20 is fixedly connected to the sewage tank 1. A second support frame 21 is fixedly connected to the outer wall of the storage box 20. A second motor 22 is fixedly connected to the inner side of the second support frame 21. A spiral blade 23 is fixedly connected to the output end of the second motor 22. A discharge port 24 is opened on one side of the storage box 20. Drainage outlets 25 are evenly opened at the bottom of the storage box 20. A water collection plate 26 is fixedly connected to the bottom of the storage box 20. The water collection plate 26 is inclined towards the sewage tank 1. Drainage outlets 27 are evenly opened on the outer wall of the sewage tank 1 near the water collection plate 26. The collection of debris and water in the storage box 20 is filtered by the cooperation of drainage outlets 25, water collection plate 26, and drainage outlets 27 to prevent odor. The cleaning net 18 is inclined towards the feed hopper 19. Multiple sets of grating plates 9 are evenly distributed on one side of the chain 8. Multiple sets of grating plates 9 ensure more thorough wastewater treatment. A handle 15 is fixedly connected to the end of the threaded rod 14 away from the rotating seat 13. Motor 1 3 and Motor 2 22 are electrically connected to an external power source.

[0028] In operation, this utility model works as follows: When sewage in sewage tank 1 needs to be treated by a sewage treatment bar screen, motor 3 is started. Motor 3 drives support rod 4, gear 5, support rod 6, gear 7, and chain 8 to rotate. This, in turn, drives the bar screen 9 and rake teeth 10 to move via chain 8. During the movement of rake teeth 10, debris is collected from sewage tank 1. When the debris in the sewage is small and difficult to collect by rake teeth 10, the operator manually rotates handle 15. Rotation of handle 15 drives threaded rod 14 to rotate. Since threaded rod 14 is threadedly connected to bar screen 9, rotation of threaded rod 14 drives T-shaped slider 12 to move, thereby adjusting the position of rake teeth 16 and thus adjusting the spacing of the rake teeth group composed of rake teeth 10 and rake teeth 16. The system is adjustable to suit actual needs and facilitates use. The chain 8 moves the rake teeth 10 and 16 upwards. When the rake teeth 10 and 16 reach the cleaning net 18, the staggered chain 8 pushes the garbage down, allowing it to enter the storage bin 20 along the cleaning net. Simultaneously, water within the garbage accumulates downwards and then returns to the sewage tank 1 through the combined action of drain outlet 25, water collection plate 26, and drain outlet 27. This prevents the damp garbage from producing odors and causing environmental pollution when temperatures are high. When the storage bin 20 is full, motor 22 is activated, driving the spiral blade 23 to rotate and push the garbage out through the discharge port 24. This eliminates the need for manual cleaning by staff, making the cleaning process relatively quick.

[0029] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
