[0002] Wastewater treatment equipment is a key facility used to treat various types of wastewater to meet environmental discharge standards or reuse standards. It typically includes multiple functional units, such as screens, which are used to initially intercept large suspended solids and debris in wastewater; and sedimentation tanks, which separate settleable solids in wastewater through gravity settling.

A frame is fixedly connected to the inner wall of the concave flow channel, and a filter screen is fixedly connected to the inner wall of the frame. Guide rods extend from both sides of the upper end of the frame.

An insert block is fixedly connected to the lower end of the horizontal plate, and a spring is fixedly connected between the upper end of the horizontal plate and the two baffles. The beneficial effect of this utility model is that when using a primary filter to pre-filter some visible impurities in industrial wastewater, it can intercept bag-shaped objects with a large surface area floating on the water surface or drifting near the water surface in front of the primary filter, preventing the bag-shaped objects from adhering to the surface of the primary filter and easily causing blockage. This is beneficial to wastewater treatment, and the intercepted bag-shaped objects are easy to remove.

[0004] Existing technologies often have the following drawbacks: during the actual use of wastewater treatment devices, dirt tends to accumulate on the bottom of the filter plates and grooved channels. This dirt is not easy to clean directly, thus affecting the filtration and treatment effect of wastewater.

[0005] Therefore, this utility model provides an environmental engineering wastewater treatment device. Utility Model Content

[0011] Preferably, a stop block is fixedly connected to the surface of the connecting plate.

[0012] The effect achieved by the above components is that the stop block prevents the slider on the guide frame from being pulled out from the inside of the groove.

[0013] Preferably, a conical rod is slidably connected inside the limiting frame, and a circular block is fixedly connected to the upper end of the conical rod.

[0014] The effect achieved by the above components is that the cone rod is inserted into the inside of the pull rope, thereby fixing the pull rope after it is pulled.

[0031] Reference Figure 1 As shown, this utility model provides a technical solution: an environmental engineering wastewater treatment device, including a grooved flow channel 1, a filter plate 2 fixedly installed on the inner side of the grooved flow channel 1, a plurality of first filter holes 3 evenly opened on the surface of the filter plate 2, a lifting structure 4 provided on the surface of the filter plate 2, and an adjustment device 5 provided on the inner side of the filter plate 2.

[0032] The following section will describe in detail the specific setup and function of its lifting structure 4 and adjusting device 5.

[0033] Reference Figure 1 and Figures 3-5As shown in this embodiment: the lifting structure 4 includes two slids 401 formed inside the grooved flow channel 1. Slider 405s are slidably connected to the inner sides of both slids 401. A guide frame 403 is fixedly installed on the side of the two sliders 405 that is close to each other. The lower side of the guide frame 403 has an inverted V-shaped structure. A pull rope 402 is fixedly connected to the inner side of the guide frame 403. A limit frame 411 is fixedly connected to the side wall of the grooved flow channel 1. The pull rope 402 is located inside the limit frame 411. A ball 404 is fixedly connected to the other end of the pull rope 402. A connecting plate 406 is fixedly connected to the surface of the filter plate 2. A rotating shaft 408 is fixedly connected inside the connecting plate 406. A pulley 410 is rotatably connected to the side wall of the rotating shaft 408. By setting up the lifting structure 4, the guide frame 403 is flexibly lifted, facilitating the periodic and flexible guidance and treatment of accumulated impurities, and avoiding the accumulation of a large amount of impurities. A retaining frame 409 is fixedly connected to the side wall of the rotating shaft 408, and the pull rope 402 is located between the retaining frame 409 and the pulley 410. The retaining frame 409 prevents the pull rope 402 from coming off the pulley. A stop block 407 is fixedly connected to the surface of the connecting plate 406. The stop block 407 prevents the slider 405 on the guide frame 403 from being pulled out from the inside of the groove 401. A conical rod 412 is slidably connected inside the limiting frame 411, and a circular block 413 is fixedly connected to the upper end of the conical rod 412. The conical rod 412 is inserted into the inside of the pull rope 402, thus fixing the pull rope 402 after it is pulled out. A spring 414 is sleeved on the surface of the conical rod 412, and the two ends of the spring 414 are fixedly connected to the circular block 413 and the limiting frame 411, respectively. The conical rod 412 is inserted into the inside of the pull rope 402 by the elastic force of the spring 414 between the limiting frame 411 and the circular block 413.

[0034] Reference Figures 1-2 and Figure 6 As shown, specifically, the adjusting device 5 includes an adjusting plate 51 slidably connected to the inner side of the filter plate 2. The surface of the adjusting plate 51 is evenly provided with a plurality of second filter holes 52, and both the first filter hole 3 and the second filter hole 52 are diamond-shaped holes. By setting the adjusting device 5, the misalignment adjustment of the first flow hole 3 and the second filter hole 52 is facilitated, enabling the filtration of different particulate impurities and meeting the needs of different users. A first auxiliary block 53 is fixedly installed on the upper surface of the adjusting plate 51, and a lead screw 55 is threadedly connected to the inside of the first auxiliary block 53. A second auxiliary block 54 is fixedly connected to the side wall of the filter plate 2, and the lead screw 55 and the second auxiliary block 54 are rotatably connected internally. Rotating the lead screw 55 allows the adjusting plate 51 inside the filter plate 2 to move, thus enabling the misalignment adjustment of the first filter hole 3 and the second filter hole 52.

[0035] Working principle: After sedimentation, impurities tend to settle on the inner side of the guide frame 403. When it is necessary to clean the impurities on the inner side of the guide frame 403, the cone rod 412 is pulled up first. At this time, the ball 404 is pulled, and the pull rope 402 slides on the surface of the pulley 410, which changes the direction of the pull force of the pull rope 402. The baffle 409 is set to prevent the pull rope 402 from coming off the pulley. At this time, the guide frame 403 can be lifted. The slider 405 moves inside the groove 401, which restricts the movement direction of the guide frame 403. The baffle 407 is set to prevent the slider 405 on the guide frame 403 from being pulled out from the inside of the groove 401. When the guide frame 403 moves beyond the surface of the groove channel 1, the impurities will flow down the lower side of the guide frame 403. The flow is directed to both sides of the groove channel 1 from the inclined surface, thus guiding the deposited impurities. At this time, the cone rod 412 is released, and the cone rod 412 will be inserted into the inside of the pull rope 402 by the elastic force of the spring 414 between the limiting frame 411 and the circular block 413, thus fixing the pull rope 402 after it is pulled out. This can temporarily support the guide frame 403 after it is lifted, which facilitates the treatment of impurities inside the guide frame 403. When the cone rod 412 is pulled out, the tip of the cone rod 412 is pulled out from the surface of the pull rope 402. At this time, the guide frame 403 will fall to the bottom of the groove channel 1 under its own weight. By setting the lifting structure 4, the guide frame 403 can be flexibly lifted, which facilitates the periodic and flexible guidance and treatment of accumulated impurities and avoids the accumulation of a large number of impurities.

[0036] By rotating the lead screw 55, the inner adjusting plate 51 of the filter plate 2 can be moved, which allows for the misalignment adjustment of the first filter hole 3 and the second filter hole 52. This facilitates the filtration of impurities of different particle sizes. Furthermore, when impurities become stuck between the filter plate 2 and the adjusting plate 51, the overlapping gap between them can be enlarged to clear the stuck impurities. By setting the adjusting device 5, the misalignment adjustment of the first filter hole 3 and the second filter hole 52 is facilitated, making it easier to filter impurities of different particle sizes and meeting the needs of different users.
