[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figures 1 to 3, which is the first embodiment of the utility model, and this embodiment provides a technical solution: a heavy metal filtration and extraction device for industrial wastewater, comprising a main body 1 and a filter plate 2 fixed on the inner side of the main body 1, and a plurality of water filter holes are evenly opened on the filter plate 2, so that industrial wastewater can fall on the filter plate 2 and be filtered after entering the inner side of the main body 1, and the heavy metal particles in the wastewater will be blocked and filtered, and the wastewater will fall from the water filter holes to the inner bottom end of the main body 1, and the left side surface of the main body 1 is provided with a water inlet pipe 11, and the left side surface of the main body 1 is provided with a water inlet pipe 11. 11, a water inlet 12 is provided on the bottom surface of the main body 1, a drain port 13 is provided, and a sweeping structure is provided on the inner side of the main body 1, the sweeping structure includes an inclined slide 31, an inclined slide plate 32, a movable brush strip 33 and bristles 34, and inclined slides 31 are provided on the inner walls of both sides of the main body 1, and strip sliders are welded and fixed on the front and rear surfaces of the inclined slide plate 32, and the strip sliders are slidably located in the inclined slides 31, and the inclined slide plate 32 is slidably located on the inner side of the main body 1, and the inclined slide plate 32 is located above the filter plate 2, so that the inclined slide plate 32 can be on the filter plate 2. The upper part slides left and right, and a movable brush strip 33 is arranged on the surface of the inclined slide plate 32. The bottom end of the movable brush strip 33 penetrates to the bottom of the inclined slide plate 32 and is fixed with a plurality of bristles 34, so that after the movable brush strip 33 slides down, the bristles 34 will contact the top surface of the filter plate 2. At this time, the inclined slide plate 32 is slid to the right again, and the metal particles filtered and accumulated on the top of the filter plate 2 can be scraped and discharged to the slag discharge port 14, thereby completing the filtration and extraction of heavy metal particles in industrial wastewater. A slag discharge port 14 is provided on the right surface of the main body 1 relative to the bottom end of the filter plate 2. 4. A detachable sealing structure is provided at the slag discharge port 14, and the detachable sealing structure includes a sealing plate 41 and a rubber plug block 42. The rubber plug block 42 is glued and fixed to the left surface of the sealing plate 41, and the sealing plate 41 is fixed to the outer surface of the main body 1 by bolts, and the rubber plug block 42 is inserted into the inner side of the slag discharge port 14 to seal the slag discharge port 14. The slag discharge port 14 can be sealed during daily filtration of industrial wastewater to prevent wastewater leakage. When the metal particles filtered from the top of the filter plate 2 need to be scraped and collected later, the sealing plate 41 and the rubber plug block 42 can be removed.

[0019] Among them, bolt holes are opened on the two end surfaces of the sealing plate 41, and thread grooves are opened on the outer surface of the main body 1 relative to the top and bottom of the slag discharge port 14, so that the sealing plate 41 can be smoothly fixed to the outer surface of the main body 1 by two bolts.

[0020] The surface of the inclined slide plate 32 is penetrated with a through hole 321 corresponding to the movable brush bar 33, and an end plate 35 is welded and fixed to the top of the movable brush bar 33. The end plate 35 is located above the inclined slide plate 32. The interior of the inclined slide plate 32 is provided with an inner groove 36 relative to the left side of the through hole 321. A spring 37 and a telescopic block 38 are arranged in the inner groove 36. Two side grooves 39 corresponding to the telescopic block 38 are arranged on the left side surface of the movable brush bar 33. The telescopic block 38 is movably installed in the inner groove 36 by the spring 37, and the right end of the telescopic block 38 pops out into one of the side grooves 39, so that after the movable brush bar 33 slides up and down, the end of the telescopic block 38 will be in the spring Under the push of the spring 37, it is stuck in a side slot 39 to realize the locking limit after the movable brush strip 33 slides up and down. In actual use, industrial wastewater will be input into the inner side of the main body 1 through the water inlet pipe 11 and the water inlet 12, and fall on the top of the filter plate 2, so that the heavy metal particles in the wastewater are blocked and filtered, and the wastewater falls to the inner bottom end of the main body 1 and is discharged from the drain port 13. The heavy metal particles in the wastewater will be filtered on the top of the filter plate 2. When the heavy metal particles filtered from the top of the filter plate 2 accumulate to a certain extent, the operator first removes the two fixing bolts on the sealing plate 41, and then moves the sealing plate 41 sideways, so that the rubber plug block 42 is pulled out, and the slag discharge port 14 is opened. Then the movable brush bar 33 is pressed down forcefully so that the end of the telescopic block 38 is first squeezed into the inner side of the inner groove 36, so that the movable brush bar 33 can slide down smoothly until the end plate 35 is in contact with the top surface of the inclined slide plate 32. At this time, the end of the telescopic block 38 will be inserted into the other side groove 39 under the push of the spring 37, so as to achieve the locking limit after the movable brush bar 33 slides down. At this time, the bristles 34 will contact the top surface of the filter plate 2. The operator only needs to slide the inclined slide plate 32 down along the inclined slide 31, and the heavy metal particles on the top of the filter plate 2 can be swept to the slag discharge port 14 by the bristles 34 to complete the collection of heavy metal particles.

[0021] One end of the spring 37 is fixed to the inner wall of the inner groove 36 , and the other end of the spring 37 is fixedly connected to the telescopic block 38 to ensure the installation stability of the spring 37 .

[0022] Example 2

[0023] See also Figures 1 to 4 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the inclined slide plate 32 can be stably limited during daily use by setting an auxiliary limiting structure.

[0024] Specifically, an L-shaped rubber pad 310 is glued and fixed to the inner wall of the left side of the main body 1. The L-shaped rubber pad 310 is made of fluororubber and will undergo elastic deformation when squeezed. An auxiliary limiting structure is provided between the L-shaped rubber pad 310 and the inclined slide 32. The auxiliary limiting structure includes a triangular protrusion 311 and a rectangular slot 312. A triangular protrusion 311 is fixed to the top of the left end of the inclined slide 32. A rectangular slot 312 corresponding to the triangular protrusion 311 is provided on the bottom surface of the L-shaped rubber pad 310. The protrusion 311 is embedded in the rectangular groove 312, so that when the inclined slide plate 32 slides to the bottom of the L-shaped rubber pad 310, the triangular protrusion 311 will squeeze into the rectangular groove 312, thereby realizing auxiliary limiting of the inclined slide plate 32. If the inclined slide plate 32 is to be slid down to scrape the heavy metal isolation on the top surface of the filter plate 2 later, the inclined slide plate 32 only needs to be pushed forcefully to the lower right so that the triangular protrusion 311 is squeezed out of the rectangular groove 312, and the inclined slide plate 32 can be smoothly slid down to perform the scraping action.
