Abstract
Description
Technical Field
[0001] This utility model relates to the field of filtration equipment, and in particular to an industrial wastewater filtration device. Background Technology
[0002] Industrial wastewater filtration equipment is a key device used to remove suspended solids, particles, colloids, and partially dissolved impurities from industrial wastewater to meet wastewater discharge standards or achieve wastewater reuse. This includes a bar screen, which can trap larger suspended and floating solids in wastewater to prevent blockages in subsequent pipes. It is typically installed before the inlet of the treatment system or pumping station, placed at an angle within the wastewater channel for easy removal of trapped material.
[0003] However, existing bar screen storage machines are prone to clogging by long fibers, plastic bags, and other easily entangled debris, leading to a reduction in the screen cross-section, increased flow velocity, decreased interception efficiency, and even overflow of the screen channel. Furthermore, traditional bar screens have large gaps, making them unable to intercept small debris, thus increasing the load on subsequent processing units. The rake teeth also lack sufficient penetration force for large pieces of debris, resulting in unsatisfactory cleaning performance.
[0004] Therefore, this utility model proposes an industrial wastewater filtration device. Utility Model Content

The bar screen mechanism, located within the filter tank, is used to transfer waste materials from the wastewater. The waste bin, fixedly located at the top of the filter tank below the outlet of the bar screen mechanism, is used to collect waste materials. The longitudinal compression mechanism, located within the filter tank, is used to compress the waste materials from both top and bottom. The longitudinal compression mechanism includes a drive component; an upper pressure plate is mounted on the drive component; the upper pressure plate is driven to move up and down by the drive component; a lower pressure plate is fixedly connected to the bottom of the filter tank directly below the upper pressure plate. The transverse compression mechanism, mounted on the longitudinal compression mechanism, is used to compress the waste materials from both left and right sides.

The compressed waste materials are also more easily intercepted and transported as they pass through the chain conveyor, preventing excessively large waste materials from being caught by the rake teeth or excessively small waste materials from slipping through the gaps in the chain conveyor, thereby improving filtration efficiency. Simultaneously, due to the reduced risk of chain conveyor blockage, the frequency of chain conveyor cleaning is correspondingly reduced, thereby lowering manual cleaning costs and equipment downtime.

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.
[0027] like Figure 1-5 As shown in the figure, an industrial wastewater filtration device provided by this utility model includes a filter tank 1, a bar screen mechanism 2, a waste bin 3, a longitudinal compression mechanism 4, and a transverse compression mechanism 5. The filter tank 1 has an inlet on one side and an outlet on the other side. The bar screen mechanism 2 is installed inside the filter tank 1 for conveying waste materials in the wastewater. The waste bin 3 is fixedly installed at the upper end of the filter tank 1, below the outlet of the bar screen mechanism 2, for collecting waste materials. The longitudinal compression mechanism 4 is installed inside the filter tank 1 for squeezing the waste materials from both the top and bottom. The longitudinal compression mechanism 4 includes a driving component; an upper pressure plate 45 is installed on the driving component; the upper pressure plate 45 is driven to move up and down by the driving component; a lower pressure plate 48 is fixedly connected to the bottom of the filter tank 1 directly below the upper pressure plate 45. The transverse compression mechanism 5 is installed on the longitudinal compression mechanism 4 for squeezing the waste materials from both the left and right sides; the transverse compression mechanism 5 includes two side pressure plates 54; the two side pressure plates 54 are driven to move laterally relative to each other by the driving component.
[0028] Further explanation: The bar screen mechanism 2 includes side plates 21 fixedly mounted on both sides of the filter tank 1; multiple rotating shafts 23 are rotatably connected between the two side plates 21; a motor 24 is provided on one side of the side plate 21; the drive end of the motor 24 is connected to one of the rotating shafts 23; sprockets 22 are provided on both sides of the multiple rotating shafts 23; chains 25 are wound around the sprockets 22 on the same side; a chain belt 26 is connected between the chains 25 on both sides; multiple rake teeth 27 are evenly provided on the chain belt 26. The chain belt 26 is inclined as a whole; by starting the motor 24, the connected rotating shafts 23 can be rotated, thereby driving the sprockets 22 to rotate, and then driving the chain belt 26 to drive the multiple rake teeth 27 to transport the waste obliquely upwards, and finally dump the waste into the waste bin 3 for collection.
[0029] To further explain, multiple sets of longitudinal compression mechanisms 4 are equidistantly arranged within the filter tank 1; correspondingly, multiple sets of transverse compression mechanisms 5 are also equidistantly arranged. This allows for simultaneous longitudinal and transverse compression of waste materials in multiple locations within the filter tank 1, resulting in high compression efficiency. The driving components include fixed frames 41 respectively fixedly mounted on both sides of the filter tank 1; each fixed frame 41 is rotatably connected to a lead screw 42; each fixed frame 41 is also equipped with a second motor 43; the two second motors 43 operate synchronously; the drive ends of the second motors 43 are respectively connected to the corresponding lead screws 42; each lead screw 42 is threadedly connected to a first connecting frame 44; the other ends of both first connecting frames 44 are connected to an upper pressure plate 45. Grooves are provided at the lower end of the upper pressure plate 45 and the upper end of the lower pressure plate 48. By starting the second motor 43, the connecting frame 44 and the upper pressure plate 45 can be driven to press down, and finally the upper pressure plate 45 and the lower pressure plate 48 will abut against each other, so that the upper pressure plate 45 and the lower pressure plate 48 cooperate to squeeze the waste material and make the waste material form a groove shape.
[0030] To further explain, multiple binding rods 46 are evenly fixed to the lower end of the upper pressure plate 45; multiple through holes 49 are opened on the lower pressure plate 48; the multiple binding rods 46 and the multiple through holes 49 are correspondingly inserted into each other. The multiple binding rods 46 can intercept waste material in advance, and at the same time, they can be inserted into the waste material during the pressing process to prevent the waste material from escaping during the compression. Each binding rod 46 has a collar 47 on its side wall. The collar 47 can limit the waste material on the multiple binding rods 46, and when the upper pressure plate 45 moves the multiple binding rods 46 upward, the waste material moves upward with the multiple binding rods 46. This prevents the waste material from accumulating in the lower pressure plate 48 and causing blockage. Two sets of uprights 410 are fixedly installed at the bottom of the filter tank 1. The two sets of uprights 410 are respectively set on both sides of the lower pressure plate 48, and the upper ends of the uprights 410 are fixedly connected to the limit plates 411. Each limit plate 411 has an elastic plate 412 on one side. The two sets of uprights 410 are slidably connected to the discharge plate 413. The discharge plate 413 has multiple through holes 414. The multiple through holes 414 are inserted into multiple collars 47 one by one. The upper end of the discharge plate 413 is in contact with the inner wall of the groove at the lower end of the upper pressure plate 45. When the upper pressure plate 45 is pressed down, the discharge plate 413 can move down with the upper pressure plate 45. When the upper pressure plate 45 moves up, the waste is limited on multiple tie rods 46, which can drive the discharge plate 413 to move up. When the unloading plate 413 moves to abut against the limiting plate 411, the upper pressure plate 45 continues to move upward, while the unloading plate 413 is locked in multiple elastic plates 412, thereby preventing the waste from moving upward and unloading the waste from multiple tie rods 46, so that the extruded waste can flow with the water flow to the grid mechanism 2.
[0031] Further explanation: The transverse compression mechanism 5 includes mounting boxes 51 fixedly installed on both sides of the filter tank 1; each mounting box 51 has a slider 52 slidably connected inside; the upper side of the slider 52 is provided with a ramp, and a sliding rod 53 is fixedly connected to one side; the other end of the sliding rod 53 passes through the filter tank 1 and is connected to the side pressure plate 54; the lower end of the side pressure plate 54 is in contact with the inner wall of the groove opened on the lower pressure plate 48; when the upper pressure plate 45 and the lower pressure plate 48 abut against each other, the cross-section of the cavity formed by the two grooves matches the cross-section of the side pressure plate 54; a spring 55 is connected between the side of the slider 52 facing the filter tank 1 and the mounting box 51. A connecting bracket 56 is also threadedly connected to the lead screw 42; the lower end of the connecting bracket 56 passes through the mounting box 51 and is fixedly provided with a connecting plate 57; the connecting plate 57 abuts against the ramp provided on the slider 52. By starting motor 43, connecting frame 56 and connecting plate 57 can be moved downwards, thereby pushing the sliders 52 on both sides to move towards each other and compress spring 55. At the same time, the sliding rods 53 and side pressure plates 54 on both sides move towards each other to laterally compress the waste material. After the compression is completed, the spring 55 rebounds and drives the sliders 52 to reset.
[0032] The vertical compression mechanism 4 and the horizontal compression mechanism 5 work together to compress the waste material from both the horizontal and vertical directions, forming it into a compact, elongated shape. This reduces the accumulation and entanglement of loose waste on the chain belt 26, lowering the risk of blockage and allowing the screen mechanism 2 to operate continuously and stably, thus improving wastewater throughput. The compressed waste material is also more easily intercepted and transported as it passes through the chain belt 26, preventing it from being too large to be caught by the rake teeth 27 or too small to slip through the gaps in the chain belt 26, thereby improving filtration efficiency. Simultaneously, the reduced risk of blockage in the chain belt 26 decreases the frequency of cleaning it, thus reducing manual cleaning costs and equipment downtime.
[0033] The working principle of this utility model is as follows: During operation, the starting motor 43 drives the lead screw 42 to rotate, thereby driving the connecting frame 44 and the upper pressure plate 45 to press down. This causes the upper pressure plate 45 and the lower pressure plate 48 to abut against each other, thus allowing the upper pressure plate 45 and the lower pressure plate 48 to cooperate in longitudinally compressing the waste material. The rotation of the lead screw 42 synchronously drives the connecting frame 56 to move downward, thereby pushing the sliders 52 on both sides to move towards each other and compress the spring 55. At the same time, it drives the sliding rods 53 on both sides and the side pressure plate 54 to move towards each other to laterally compress the waste material. After compression, when the upper pressure plate 45 moves upward, the waste material is limited on multiple tie rods 46, thereby driving the unloading plate 413 to move upward. When the unloading plate 413 moves to abut against the limiting plate 411, the upper pressure plate 45 continues to move upward, while the unloading plate 413 is engaged within multiple elastic plates 412, thereby preventing the waste material from moving upward and unloading it from the multiple tie rods 46, allowing the extruded waste material to flow with the water flow to the grid mechanism 2. At the same time, the spring 55 rebounds, causing the slider 52 to reset.
[0034] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
