Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a bar screen for wastewater treatment. Background Technology

[0002] As is well known, a bar screen is a special water treatment device that can continuously and automatically intercept and remove debris of various shapes from fluids. It can be widely used in urban sewage treatment, tap water industry, power plant inlets, and can also be used as a pre-screening device in wastewater treatment processes in industries such as textiles, food processing, papermaking, and leather.

[0003] For example, Chinese patent application number CN202222303591.2 discloses a bar screen for sewage treatment, comprising a housing and a bar screen; the housing has an open structure on its left side, and a slag discharge pipe is provided at the slag discharge port on the upper right side of the housing. First rotating columns are rotatably connected between the front and rear inner walls of the housing via rotating shafts. The front and rear ends of the two first rotating columns are connected by synchronous belt drives, and toothed rake plates are provided between the two synchronous belts. A support cylinder is provided on the top wall of the slag discharge pipe, and a sliding column is slidably connected inside the support cylinder; the bar screen is installed in the mounting hole at the lower right side of the housing. This bar screen for sewage treatment can continuously separate solid pollutants from sewage, facilitating the adjustment of the bar screen gap without the need to replace the bar screen, reducing the adjustment time, making the overall device more widely applicable and more usable, and improving the sewage treatment efficiency.

[0004] However, in actual use, the above-mentioned device directly treats sewage through the screen. But sewage usually contains oil stains. If the oil stains are not absorbed in advance, the screen will easily become clogged after long-term use, eventually causing the screen to fail to filter and affecting the sewage treatment effect. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bar screen for sewage treatment. A U-shaped fixing rod drives the clamping frame to rise and fall, which in turn drives the clamping frame to bring polypropylene meltblown nonwoven fabric into full contact with the sewage to absorb oil stains. This effectively removes oil stains from the sewage, preventing them from affecting subsequent waste filtration due to prolonged use, thus improving the overall performance and effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a bar screen for sewage treatment, comprising a body fixedly connected to the front end of a sewage treatment system, wherein a slag discharge pipe is fixedly provided on the front side of the body;

[0007] The slag discharge pipe is equipped with an oil absorption component to absorb oil stains in the sewage.

[0008] The bottom of the slag discharge pipe is equipped with a grid assembly for filtering waste of different sizes;

[0009] The oil absorption assembly includes a threaded rod, and slots are opened inside both sides of the slag discharge pipe. The top and bottom ends of the threaded rod are connected between the top and bottom ends of a slot by bearings. A threaded block is connected to the threaded rod by threads. Two opposing snap-fit ​​frames are provided inside the slag discharge pipe, and the same polypropylene meltblown nonwoven fabric is snapped between the two snap-fit ​​frames.

[0010] Preferably, a limiting rod is fixed between the top and bottom of the other slot, a limiting block is slidably provided on the limiting rod, and a U-shaped fixing rod is fixed on one side of the top of the threaded block and the limiting block. Two limiting grooves are opened on both sides of the top of the slag discharge pipe, and the top of the U-shaped fixing rod passes through the two limiting grooves. The bottom end of the U-shaped fixing rod away from the groove is fixed on one side of the top of the snap-fit ​​frame, so that the U-shaped fixing rod can lift and lower to drive the snap-fit ​​frame to lift and lower.

[0011] Preferably, the bottom four corners of the snap-fit ​​frame are all threadedly connected with bolts for fixing the two snap-fit ​​frames together. A first motor is fixedly installed on one side of the top of the slag discharge pipe. The output shaft of the first motor passes through the slag discharge pipe and is fixedly connected to the top of the threaded rod, so that the first motor can rotate to drive the threaded rod to rotate.

[0012] Preferably, the grid assembly includes a fixing frame, a fixing frame is fixedly provided on one side of the fixing frame, and a plurality of rotating shafts evenly distributed vertically are connected between the two sides inside the fixing frame through bearings. A grid plate is fixedly provided on the rotating shaft, so that the rotating shaft can rotate to drive the grid plate to rotate.

[0013] Preferably, one end of each of the rotating shafts passes through the fixed frame and is connected to the inner wall of the fixed frame via bearings. Gears are fixedly mounted on the rotating shafts, and the gears mesh with each other and are disposed inside the fixed frame.

[0015] Compared with the prior art, the present invention provides a bar screen for sewage treatment, which has the following beneficial effects:

[0016] 1. This utility model uses the rotation of the threaded rod to drive the threaded block to rise and fall, which in turn causes the U-shaped fixing rod to drive the snap-fit ​​frame to rise and fall. The snap-fit ​​frame drives the polypropylene meltblown nonwoven fabric to fully contact the sewage to adsorb the oil stains in the sewage, thereby achieving the adsorption of oil stains. Furthermore, the polypropylene meltblown nonwoven fabric can be easily replaced by unscrewing the bolts, so as to remove oil stains from the sewage and avoid the oil stains from affecting the subsequent garbage filtration due to long-term use, thus improving the use effect.

[0017] 2. This utility model uses a second motor to drive several gears to mesh and rotate. The rotation of the gears will drive the rotating shaft to rotate, and the rotation of the rotating shaft will drive several grid plates on it to rotate, so that the grid plates are tilted to different angles. This allows users to filter garbage of different sizes according to the actual situation, thereby improving the effect of sewage treatment. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-6As shown, this utility model provides a bar screen for sewage treatment, including a body 1 fixedly connected to the front end of a sewage treatment system. A slag discharge pipe 2 is fixedly provided on the front side of the body 1. An opening is provided on the front bottom side of the slag discharge pipe 2. A guide plate 9 is fixedly provided at the bottom inside the slag discharge pipe 2 and is located behind the opening. A snap-fit ​​groove 6 is provided in the rear wall of the opening. A pull plate 7 is provided through the bottom front side of the slag discharge pipe 2 and is snapped into the snap-fit ​​groove 6 on the rear side.

[0028] like Figure 1-4 As shown, the slag discharge pipe 2 is equipped with an oil absorption component 3 for adsorbing oil stains in sewage. The oil absorption component 3 includes a threaded rod 31. The slag discharge pipe 2 has slots 10 on both sides. The top and bottom ends of the threaded rod 31 are connected to the top and bottom ends of one slot 10 through bearings. A threaded block 32 is threadedly connected to the threaded rod 31. The slag discharge pipe 2 has two opposing snap-fit ​​frames 36. The same polypropylene meltblown nonwoven fabric 37 is snapped between the two snap-fit ​​frames 36. The same limiting rod 33 is fixed between the top and bottom ends of the other slot 10. A limiting block 34 is slidably provided on the limiting rod 33. A U-shaped fixing rod 35 is fixed on one side of the top of the threaded block 32 and the limiting block 34.

[0029] Two limiting grooves 8 are provided on both sides of the top of the slag discharge pipe 2. The top of the U-shaped fixing rod 35 passes through the two limiting grooves 8. The bottom end of the U-shaped fixing rod 35, away from the groove 10, is fixed to the top side of the snap-fit ​​frame 36, so that the U-shaped fixing rod 35 can lift and lower, driving the snap-fit ​​frame 36 to lift and lower. The bottom four corners of the snap-fit ​​frame 36 are all connected by threads to bolts 38 for fixing the two snap-fit ​​frames 36. A first motor 39 is fixedly provided on the top side of the slag discharge pipe 2. The output shaft of the first motor 39 passes through the slag discharge pipe 2 and is fixedly connected to the top of the threaded rod 31, so that the first motor 39 can rotate and drive the threaded rod 31 to rotate. A control panel 5 for controlling the operation of the first motor 39 is fixedly provided on the front side of the slag discharge pipe 2.

[0030] By setting the oil suction component 3, this utility model is connected to the front end of the sewage treatment system. Sewage is filled into the machine body 1 and the slag discharge pipe 2. The control panel 5 controls the first motor 39 to work. The first motor 39 drives the threaded rod 31 to rotate and drives the threaded block 32 on it to rise and fall along the threaded rod 31, so that the U-shaped fixing rod 35 drives the snap-fit ​​frame 36 to rise and fall, and at the same time drives the limit block 34 to rise and fall along the limit rod 33 to limit the movement of the snap-fit ​​frame 36.

[0031] Based on the liquid level in the sewage discharge pipe 2, the snap-fit ​​frame 36 can be driven to move the polypropylene meltblown nonwoven fabric 37 up and down, allowing the polypropylene meltblown nonwoven fabric 37 to fully contact the sewage and absorb the oil stains in the sewage. At the same time, when the polypropylene meltblown nonwoven fabric 37 is close to saturation, the bolts 38 at the four corners of the snap-fit ​​frame 36 can be unscrewed, the bottom snap-fit ​​frame 36 can be removed and a new polypropylene meltblown nonwoven fabric 37 can be replaced, and then the two snap-fit ​​frames 36 can be fixed together, which facilitates the replacement of the polypropylene meltblown nonwoven fabric 37, so as to remove the oil stains in the sewage, avoid the oil stains from affecting the subsequent garbage filtration due to long-term use, and improve the use effect.

[0032] like Figure 1-3 As shown in Figure 5, the bottom of the slag discharge pipe 2 is provided with a grid assembly 4 for filtering garbage of different sizes. The grid assembly 4 includes a fixed frame 41, and a fixed frame 42 is fixedly provided on one side of the fixed frame 41. Several rotating shafts 43 are evenly distributed vertically between the two sides inside the fixed frame 41 through bearings. A grid plate 44 is fixedly provided on the rotating shaft 43 to facilitate the rotation of the rotating shaft 43 and drive the grid plate 44 to rotate. One end of several rotating shafts 43 passes through the fixed frame 42 and is connected to the inner wall of the fixed frame 42 through bearings. Gears 45 are fixedly provided on the rotating shafts 43, and several gears 45 mesh with each other and are arranged inside the fixed frame 42. A second motor 46 is fixedly provided on one side of the top of the fixed frame 42. The output shaft of the second motor 46 passes through the fixed frame 42 and is fixedly connected to one end of the top rotating shaft 43 to facilitate the second motor 46 to control the rotation of the rotating shaft 43. The second motor 46 is controlled by the control panel 5.

[0033] After the oil stains are absorbed by the grid assembly 4, the pull plate 7 is pulled out along the snap-fit ​​groove 6, allowing sewage and garbage to fall from the bottom of the slag discharge pipe 2 to the top of several grid plates 44. Since the several grid plates 44 are tilted, the garbage can slide down the several grid plates 44 to the bottom of the fixing frame 41 under its own weight. At the same time, the second motor 46 can be controlled by the control panel 5. The second motor 46 drives several gears 45 to mesh and rotate. The rotation of the gears 45 will drive the rotating shaft 43 to rotate. The rotation of the rotating shaft 43 will drive the several grid plates 44 on it to rotate, so that the several grid plates 44 are tilted to different angles. This allows the user to filter garbage of different sizes according to the actual situation, thereby improving the sewage treatment effect.
