Description

Technical Field

[0001] This utility model relates to the technical field of bar screen machines, and in particular to a bar screen machine for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. For suspended solids in wastewater, bar screens are needed for treatment. Rotary bar screens use fixed bar screens to block debris and rely on circulating rake teeth to feed and collect garbage and waste. Then, the screen rotates to remove the collected garbage from the wastewater tank.

[0003] Existing wastewater treatment bar screens use a second motor to drive a rotating shaft. The rotation of the shaft causes the connecting seat to rotate, which in turn drives the brush. The brush can rotate in contact with the surface of the screen, thus brushing off debris that is difficult to remove from the screen and achieving a self-cleaning function. However, the degree of contact between the brush and the screen surface is fixed and cannot be adjusted. When encountering highly adhesive debris, the brush's cleaning ability is low. Utility Model Content

[0004] The purpose of this utility model is to provide a bar screen for wastewater treatment to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A bar screen for wastewater treatment includes: a bar screen body, the bar screen body comprising: an intercepting net disposed inside a mounting frame; a protective box disposed on the top of the mounting frame; a drive assembly disposed on the protective box; a motor disposed on one side of the protective box; a cleaning roller disposed at the output end of the motor and located inside the protective box; an adjustment assembly disposed on the cleaning roller, the adjustment assembly comprising: a fixing sleeve symmetrically disposed at both ends of the cleaning roller; a support frame disposed outside the fixing sleeve and extending through the top of the protective box; an electric push rod disposed at the top of the protective box and located on one side of the support frame; a first sliding groove extending through the outside of the protective box and located at the output end of the motor; a positioning plate disposed between the motor and the cleaning roller and rotatably connected to the output end of the motor, wherein the first sliding groove has a positioning groove that mates with the positioning plate.

[0007] Optionally, a slider is provided at one end of the cleaning roller and is rotatably connected to the cleaning roller, and a second groove is provided on the inner side wall of the protective box to cooperate with the slider.

[0008] Optionally, rubber baffles are provided on the first and second slides.

[0009] Optionally, the bottom of the support frame is provided with a support rod, and the top of the protective box is provided with a third sliding groove that cooperates with the support rod.

[0010] Optionally, the outer side of the support rod is provided with threads, and a threaded sleeve is provided on the threads.

[0011] Optionally, the bottom of the threaded sleeve is provided with a compression plate and is sleeved on the outside of the support rod.

[0012] Optionally, an anti-slip pad is provided between the extrusion plate and the top of the protective box.

[0013] Optionally, the protective box is provided with a guide plate that works with the cleaning roller.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By activating the electric actuator, the actuator, through the support frame and in conjunction with the positioning plate and positioning groove, pushes the cleaning roller and motor to one side. This causes the brushes on the cleaning roller to press against the intercepting screen, increasing the friction between the brushes and the screen surface. This allows the rotating cleaning roller to brush off some sticky debris, facilitating the adjustment of the fit between the cleaning roller and the screen, and increasing the flexibility and practicality of the wastewater treatment bar screen.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Given that the adhesion between the brush and the surface of the interception net is fixed in the current technology and cannot be adjusted, the brush has a low cleaning efficiency when encountering highly adhesive debris.

[0027] like Figures 1-4As shown, this utility model embodiment provides a bar screen for wastewater treatment, including: a bar screen body 1, the bar screen body 1 including: an intercepting net 14 disposed inside the mounting frame 11; a protective box 12 disposed on the top of the mounting frame 11; a drive assembly 13 disposed on the protective box 12; a motor 15 disposed on one side of the protective box 12; a cleaning roller 16 disposed at the output end of the motor 15 and located inside the protective box 12; an adjustment assembly 2 disposed on the cleaning roller 16, the adjustment assembly 2 including: a fixing sleeve 22 symmetrically disposed at both ends of the cleaning roller 16; a support frame 21 disposed outside the fixing sleeve 22 and penetrating the top of the protective box 12; an electric push rod 23 disposed at the top of the protective box 12 and located on one side of the support frame 21; a first sliding groove 24 penetrating the outside of the protective box 12; a positioning plate 25 disposed between the motor 15 and the cleaning roller 16 and rotatably connected to the output end of the motor 15, the first sliding groove 24 having a positioning groove 251 that cooperates with the positioning plate 25 inside.

[0028] In use, the wastewater treatment bar screen is installed at the inlet of the water channel. Then, the drive assembly 13 is started, driving the interceptor screen 14 to rotate. The rotating screen 14 intercepts debris in the wastewater. After the debris intercepted by the screen 14 rotates back to the top, the debris hanging on the screen 14 falls out of the discharge hopper. Simultaneously, the starter motor 15 drives the cleaning roller 16 to rotate. The rotating cleaning roller 16 adheres to the surface of the screen 14, brushing off debris that is difficult to remove from the screen 14. When staff observe... After the intercepting net 14 has been rotated and some debris remains, the electric push rod 23 is activated. The electric push rod 23, through the support frame 21, works with the positioning plate 25 and the positioning groove 251 to push the cleaning roller 16 and the motor 15 to one side. This causes the brush on the cleaning roller 16 to squeeze the intercepting net 14, increasing the friction between the brush on the cleaning roller 16 and the surface of the intercepting net 14. This allows the rotating cleaning roller 16 to brush off some sticky debris, making it easier to adjust the fit between the cleaning roller 16 and the intercepting net 14. This increases the flexibility and practicality of the bar screen for wastewater treatment.

[0029] Specifically, impurities include: plant debris such as twigs, leaves, and weeds; algae clumps; lightweight plastic products such as plastic bags, plastic bottles, and foam boards; and household waste such as hair, paper towels, and wet wipes.

[0030] Specifically, the drive assembly 13 includes: a first motor fixedly connected to the upper surface of the mounting frame; an output shaft fixedly connected to the output end of the first motor; a belt sleeved on the outer surface of the output shaft; a driven shaft provided on the inner surface of the belt; the rear end face of the driven shaft slidingly penetrating the mounting frame; a drive roller fixedly connected to the rear end face of the driven shaft; a driven roller rotatably connected to the inner surface of the mounting frame; and an interception net 14 provided between the outer surfaces of the driven roller and the drive roller. Starting the motor can drive the output shaft to rotate, and the output shaft can drive the driven shaft to rotate through the belt drive. The rotation of the driven shaft can drive the drive roller to rotate, and the combined rotation of the drive roller and the driven roller can drive the interception net 14 to rotate. Through the rotation of the interception net 14, debris in the water body can be intercepted. After the debris intercepted by the interception net 14 rotates to the top, the debris hanging on the interception net 14 will fall out from the sewage hopper. This section is not shown in the accompanying drawings of the specification.

[0031] Furthermore, a slider 26 is provided at one end of the cleaning roller 16 and is rotatably connected to the cleaning roller 16. A second sliding groove 261 that matches the slider 26 is provided on the inner side wall of the protective box 12, so that the cleaning roller 16 is slidably connected to the protective box 12, thereby increasing the stability of the movement of the cleaning roller 16.

[0032] Specifically, the cleaning roller 16 is usually supported by an elongated component (roller core) that extends along the longitudinal axis. The material is mostly nylon rods, and the surface of the roller core is covered with brushes.

[0033] Furthermore, rubber baffles 27 are provided on the first chute 24 and the second chute 261 to block the openings of the first chute 24 and the second chute 261, so as to prevent debris from entering the first chute 24 and the second chute 261 and affecting the movement of the cleaning roller 16.

[0034] Furthermore, a support rod 28 is provided at the bottom of the support frame 21, and a third sliding groove 281 that cooperates with the support rod 28 is provided at the top of the protective box 12 to support the cleaning roller 16 and reduce the weight borne by the electric push rod 23 on the cleaning roller 16.

[0035] Furthermore, the outer side of the support rod 28 is provided with a thread 29, and a threaded sleeve 291 is provided on the thread 29. When the electric push rod 23 pushes the cleaning roller 16 to move through the support frame 21, the threaded sleeve 291 is rotated. The rotating threaded sleeve 291 moves downward through the thread 29 to squeeze the top of the protective box 12, and squeezes and fixes the support frame 21, increasing the stability of the cleaning roller 16 after it moves.

[0036] Furthermore, a compression plate 292 is provided at the bottom of the threaded sleeve 291 and is sleeved on the outside of the support rod 28, which increases the area of ​​the top of the compression protection box 12 of the threaded sleeve 291 and improves the stability of the compression and fixing of the support frame 21.

[0037] Furthermore, an anti-slip pad 293 is provided between the top of the extrusion plate 292 and the top of the protective box 12 to increase the anti-slip properties of the extrusion plate 292 pressing the top of the protective box 12.

[0038] Specifically, the anti-slip pad 293 is a ring-shaped piece made of polyurethane (PU).

[0039] Furthermore, the interior of the protective box 12 is equipped with a guide plate 17 that works with the cleaning roller 16 to block the impurities swept down by the cleaning roller 16 and guide them to the sewage hopper.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
