Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically a filtration device for industrial wastewater discharge. Background Technology

[0002] With the acceleration of industrialization, the amount of wastewater generated in industrial production activities is increasing day by day. Industrial wastewater contains various harmful substances, such as organic matter, heavy metals, chemicals and other pollutants. If these substances are discharged directly, they will cause serious pollution to the environment, threaten the ecological balance and may harm human health. Therefore, the development of wastewater treatment technology has become an important issue in industrial production. Among them, wastewater filtration treatment, as one of the basic steps, is of vital importance for removing suspended solids and certain dissolved substances from wastewater to meet wastewater discharge standards.

[0003] The shortcomings of existing technology:

[0004] Currently, when sewage flows through filter media, suspended solids are often trapped by the filter media due to their inherent size, shape, or physicochemical properties. Over time, these trapped suspended solids accumulate on or inside the filter layer, clogging the filter pores and causing the filtration speed to decrease or even stop completely, thus greatly reducing the filtration efficiency. Therefore, how to effectively address these technical challenges, further improve sewage filtration efficiency, and ensure the long-term stability of the filter media has become a critical issue that urgently needs to be addressed.

Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0045] 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 invention, "a number" means two or more, unless otherwise explicitly specified. Example

[0046] Please see Figure 1-10 As shown, the present invention provides a technical solution for an industrial wastewater discharge filtration device: an industrial wastewater discharge filtration device includes a wastewater channel 1, an interception mechanism 2 for removing large suspended particles is provided inside the wastewater channel 1, a support mechanism 3 for preventing the interception mechanism 2 from falling back is provided on both sides of the interception mechanism 2, and an unlocking mechanism 4 for matching the support mechanism 3 is provided on the side of the support mechanism 3.

[0047] The interception mechanism 2 includes an interception body 201, a water flow chamber 205, and several interception rods 206. The interception body 201 has a fulcrum end 202 and a free end 203 on each side. The side of the interception body 201 facing the fulcrum end 202 is rotatably connected to the inner wall of the sewage channel 1 via a fixed rotating rod 204. Both sides of the interception body 201 are connected to the support mechanism 3. The water flow chamber 205 is located inside the interception body 201. The interception rods 206 are fixedly connected to the inner side of the water flow chamber 205, and both ends of the interception rods 206 are fixedly connected to the interception body 201. The interiors of the interception body 201 and the interception rods 206 are hollow structures. During interception preparation, such as... Figure 1 As shown, the interceptor 201 is obliquely positioned in the sewage channel 1, with its fulcrum end 202 pointing upwards and its free end 203 pointing downwards. During the interception process, suspended solids drift towards the interceptor 201 along with the sewage. Upon contact with the interceptor 201, they are intercepted. As the suspended solids accumulate, subsequent suspended solids tend to move upwards or downwards. Because the interceptor 201 itself is inclined and its lower half is limited by the support mechanism 3, subsequent suspended solids will move upwards and reach the fulcrum end 202. Then, after continuous accumulation, the subsequent suspended solids, propelled by the water flow, will generate a force sufficient to lift the free end 203. When the free end 203 lifts, as... Figure 2As shown, the suspended object will be confined inside the interceptor 201, while the support mechanism 3 is self-locking to ensure that the interceptor 201 will not fall during subsequent retrieval of the suspended object. In this process, by setting the interceptor 201 to be combined with the flow direction of the suspended object, the suspended object can be naturally intercepted. By tilting the interceptor 201 and under the action of the support mechanism 3, the suspended object can be guided upward, and after accumulating to a certain extent, the free end 203 will be raised, thereby achieving further interception of the suspended object and facilitating subsequent removal. By designing the interceptor 201 and the interceptor rod 206 as a hollow structure, the structural weight can be reduced, the activity load of the support mechanism 3 can be reduced, and the thrust required to raise the free end 203 can be reduced.

[0048] The support mechanism 3 includes a rotating component 301, a receiving tube 302, a baffle plate 304, a limiting plate 307, and a connecting rod 308. The rotating component 301 is fixedly installed at the bottom of the sewage channel 1. The bottom of the receiving tube 302 is fixedly connected to the rotating component 301. The receiving tube 302 has a hollow structure, and a sliding groove 303 is formed on the tube wall. The baffle plate 304 is slidably disposed inside the sliding groove 303. The baffle plate 304 is semi-circular, and the opening diameter of the lower end face of the baffle plate 304 is larger than the opening diameter of the upper end face. A secondary pull rope 305 is connected to the side of the baffle plate 304, and the secondary pull rope 305 is connected to the unlocking mechanism 4. Springs 306 are fixedly connected to both ends of the baffle plate 304. The other end of the spring 306 is fixedly connected to the wall of the receiving tube 302. The inside of the receiving tube 302 is a hollow structure. The limiting plate 307 is fixedly connected to the inner side of the receiving tube 302. The side of the limiting plate 307 abuts against the side of the blocking plate 304. A movable end 9 is arranged at the bottom of the connecting rod 308. The movable end 9 of the connecting rod 308 is movably disposed inside the receiving tube 302. The other end of the connecting rod 308 is rotatably connected to a fixed rod 309. The fixed rod 309 is fixedly connected to the side of the interceptor 201. The cross-sectional area of ​​the movable end 9 is larger than the opening area of ​​the receiving tube 302 and smaller than the limit area of ​​the opening formed by the limiting plate 307 and the blocking plate 304. In this embodiment, the structure of the blocking plate 304 is as follows: Figure 8As shown, it includes two vertical side wings that abut against the side wall of the limiting plate 307. A ring-shaped opening is formed between the blocking plate 304 and the limiting plate 307, allowing the connecting rod 308 to pass through. When the free end 203 of the interceptor 201 tilts upward, the end portion of the connecting rod 308 rises along with it, while the movable end 9 located in the receiving tube 302 moves upward along its inner wall. When the movable end 9 is about to contact the blocking plate 304, the back of the interceptor 201 faces the water-facing direction. For the connecting rod 308... The tension will increase, and eventually, the movable end 9 will break through the restriction of the blocking plate 304, compress the spring 306, move above the blocking plate 304 and the limiting plate 307, and be confined in the space above them, thus supporting the interceptor 201. During this process, by setting the blocking plate 304 and the limiting plate 307, and setting the spring 306 on the side of the blocking plate 304, the connecting rod 308 can be self-locked after moving to the fixed position, which can effectively prevent the interceptor 201 from falling off and ensure the interception effect.

[0049] The unlocking mechanism 4 includes a movable cavity 401, a secondary steering wheel 402, a main pull rope 403, and a main steering wheel 404. The movable cavity 401 is located in the side wall of the sewage channel 1. The secondary steering wheel 402 is installed inside the movable cavity 401 and is located on the side of the secondary pull rope 305. The main pull rope 403 is arranged inside the movable cavity 401. The secondary pull rope 305 is connected to the main pull rope 403. The main steering wheel 404 is installed at the corner of the main pull rope 403 and is located on the side of the main pull rope 403. A hanging column 6 is provided on the upper surface of the side wall of the sewage channel 1. The end of the main pull rope 403 is sleeved on the hanging column 6. When unlocking the support mechanism 3, as... Figure 1-2 As shown, the worker needs to remove the main pull rope 403 from the hanging column 6 and then pull the end of the main pull rope 403. At this time, the main pull rope 403 will drive the auxiliary pull rope 305, causing the baffle plate 304 at the connecting end of the auxiliary pull rope 305 to retract and squeeze the spring 306. At this time, the movable end 9 of the connecting rod 308 is in the unlocked state. Under the push of the water flow, the movable end 9 will float slightly and slide down to the bottom of the receiving tube 302, and the interceptor 201 will reset. During this process, by opening the movable cavity 401 in the side wall of the sewage channel 1, the auxiliary steering wheel 402, the main pull rope 403, and the main steering wheel 404 can be accommodated inside the movable cavity 401, which can effectively reduce the space of the mechanism inside the sewage channel 1. By connecting the main pull rope 403 and the auxiliary pull rope 305 and with the assistance of the steering wheel, the locking of the support mechanism 3 can be quickly released by lifting, so as to facilitate the secondary interception work after cleaning.

[0050] Several limiting posts 5 are installed on the side wall of the sewage channel 1. By installing the limiting posts 5 on the side wall of the sewage channel 1, the interceptor 201 can be prevented from over-reversing, which could damage the receiving pipe 302.

[0051] Both the main steering wheel 404 and the auxiliary steering wheel 402 are equipped with baffles 7 on their sides. By installing baffles 7 on the sides of the main steering wheel 404 and the auxiliary steering wheel 402, it can be ensured that the pull rope will never detach from the surface of the guide wheel, thus ensuring stable operation.

[0052] The movable cavity 401 is provided with a limiting part 8. By providing the limiting part 8 inside the movable cavity 401, the receiving tube 302 can be prevented from overturning. On the other hand, it can provide support for the receiving tube 302 when the auxiliary pull rope 305 is pulled, so as to avoid damage to the inside of the receiving tube 302 when it is pulled.

[0053] The working principle of this invention is as follows:

[0054] In this embodiment, a filtration device for industrial wastewater discharge, during the interception preparation stage, has an interceptor body 201 obliquely positioned in the wastewater channel 1, with the fulcrum end 202 of the interceptor body 201 pointing upwards and the free end 203 pointing downwards. During the interception process, suspended solids drift towards the interceptor body 201 along with the wastewater. Upon contact with the interceptor body 201, they are intercepted. As suspended solids accumulate, subsequent suspended solids move upwards and reach the fulcrum end 202. Then, after continuous accumulation, the subsequent suspended solids, propelled by the water flow, generate a force sufficient to lift the free end 203. When the free end 203 lifts, such as... Figure 2As shown, suspended objects will be confined inside the interceptor 201. Meanwhile, the end of the connecting rod 308 will rise along with it, and the movable end 9 located in the receiving tube 302 will move upwards along its inner wall. When the movable end 9 is about to contact the baffle plate 304, the back of the interceptor 201 faces the water, increasing the tension on the connecting rod 308. Ultimately, the movable end 9 will break through the restriction of the baffle plate 304, compressing the spring 306 and moving above the baffle plate 304 and the limiting plate 307, confining it within the space above them, thus supporting the interceptor 201. When the support mechanism 3 needs to be unlocked, the main pull rope 403 on the hanging column 6 needs to be removed, and then the end of the main pull rope 403 is pulled. At this time, the main pull rope 403 will drive the auxiliary pull rope 305, causing the connecting end of the auxiliary pull rope 305 to... Plate 304 retracts and compresses spring 306. At this time, the movable end 9 of connecting rod 308 is in the unlocked state. Under the push of water flow, the movable end 9 will float slightly and slide to the bottom of receiving tube 302, and the interceptor 201 will be reset. This device can naturally capture suspended objects and guide them upward by setting interceptor 201. With the cooperation of support mechanism 3, the suspended objects can cause the free end 203 to tilt up after accumulating to a certain extent, making it easy to remove. The blocking plate 304, limiting plate 307 and spring 306 together ensure the self-locking of connecting rod 308 and prevent interceptor 201 from falling off. The movable cavity 401 simplifies the mechanism and saves space in sewage channel 1. In addition, by using the combination of main pull rope 403 and auxiliary pull rope 305, a quick unlocking function is realized, which facilitates the cleaning work after interception.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
