Description

Technical Field

[0002] With the rapid development of my country's information industry and electronics industry, circuit boards, as one of the foundations of the electronics industry, are increasing at a rate of about 20% each year and have become one of the important industries in the electronics industry. The amount of wastewater generated by circuit boards is very large. The sources of wastewater are numerous and the composition is complex. It often contains heavy metals and other harmful substances. It cannot be discharged directly. It needs to be scientifically filtered, degraded, and precipitated to ensure that the heavy metals and other harmful substances in the wastewater meet the discharge standards before discharge.

[0003] When treating the wastewater generated by the circuit board, the wastewater will first be filtered in multiple stages through multiple filtering mechanisms, and then the filtered wastewater will be discharged into the sedimentation tank. After that, flocculants will be added to the inside of the sedimentation tank to flocculate and precipitate the impurities in the wastewater. After sedimentation, the wastewater above the sediment will be discharged first, and then the sediment at the bottom of the sedimentation tank will be taken out and the inside of the sedimentation tank will be cleaned.

[0004] However, since the sedimentation tank has a certain depth, the user needs to take the sediment in the sedimentation tank out from the bottom of the tank again and again when cleaning the sediment.

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

A circuit board production wastewater treatment device comprises: a sedimentation tank 1;

[0034] A discharge port 11 is provided on the front of the sedimentation box 1. Two limiting rods 12 are fixedly installed on the inner side of the sedimentation box 1.

[0035] The side plates 2 are respectively fixedly mounted on both sides of the sedimentation box 1, and a chute 21 is opened inside the side plate 2. The bottom of the inner side surface of the chute 21 is rotatably connected with a screw rod 23. The top of the screw rod 23 is fixedly mounted with a first drive motor 24, and the bottom of the first drive motor 24 is fixedly mounted on the top of the side plate 2. The outer side surface of the screw rod 23 is threadedly connected with a movable plate 25, and the top of the movable plate 25 is fixedly mounted with a second drive motor 26. The output end of the second drive motor 26 is fixedly mounted with a stirring shaft 27, and the stirring shaft 27 is provided at the top of the movable plate 25. A fixing rod 28 is fixedly mounted on the bottom of the movable plate 25, and the fixing rod 28 is provided on one side of the stirring shaft 27. The bottom of the fixing rod 28 is fixedly mounted on the top of the filter plate 16;

[0036] A fixed frame 3 is fixedly mounted on the top of the sedimentation tank 1. A movable frame 31 is slidably connected to the interior of the front of the fixed frame 3. A metal mesh 33 is fixedly mounted on the bottom of the inner side of the movable frame 31. A sponge layer 32 is provided on the top of the metal mesh 33. Electric telescopic rods 34 are fixedly mounted on both ends of the top of the fixed frame 3. A pressing plate 35 is fixedly mounted on the movable end of the electric telescopic rod 34. The pressing plate 35 is provided on the top of the sponge layer 32.

[0037] The mounting frame 4 is fixedly mounted on the top of the fixing frame 3 , and an electromagnetic filter plate 42 is fixedly mounted on the inner side surface of the mounting frame 4 .

[0038] A valve is installed on the back of the sedimentation box 1 for discharging the wastewater inside the sedimentation box 1; the setting of the limit rod 12 can limit the scraper 13 when in use, and can also increase the stability of the movement of the scraper 13;

[0039] The movable plate 25 slides on the outer side of the slide rod 22, thereby increasing the stability of the movable plate 25 in moving up and down, and the movable plate 25 can drive the filter plate 16 to move upward through the fixed rod 28, so that the filter plate 16 moves from the bottom of the inner side of the sedimentation box 1 to the top of the sedimentation box 1;

[0040] The second drive motor 26 drives the stirring shaft 27 to rotate on the inner side of the sedimentation tank 1, so that after the flocculant is added into the sedimentation tank 1, the flocculant and the wastewater are stirred and mixed, and after the mixing, the second drive motor 26 is stopped.

[0041] The two sides of the movable plate 25 are fitted to the two sides of the inner side of the slide groove 21. The interior of both sides of the movable plate 25 is slidably connected with a slide rod 22, and the top and bottom of the slide rod 22 are fixedly installed on the top and bottom of the inner side of the slide groove 21 respectively.

[0042] The bottom of the stirring shaft 27 is disposed on the top of the filter plate 16 .

[0043] A first feed pipe 36 is fixedly mounted on the bottom of the fixing frame 3 , and a second feed pipe 41 is fixedly mounted on the bottom of the mounting frame 4 . The output end of the second feed pipe 41 is disposed on the top of the pressing plate 35 .

[0044] The size of the pressing plate 35 is the same as the size of the inner side surface of the moving frame 31 .

[0045] There are multiple leakage holes on the top of the pressing plate 35, so that the wastewater flowing out from the first discharge pipe 36 can flow through the pressing plate 35 to the top of the sponge layer 32, thereby filtering impurities in the wastewater through the sponge layer 32, and the wastewater can be filtered again through the metal mesh 33. When the metal mesh 33 and the sponge layer 32 need to be replaced and cleaned, the user can directly pull the movable frame 3 to move the movable frame 3 out from the inner side of the fixed frame 3.

[0046] The working principle of the wastewater treatment device for circuit board production provided by the present invention is as follows:

[0047] During use, the user pours the wastewater generated by the circuit board production into the inner side of the installation frame 4. At this time, the magnetic impurities in the wastewater are adsorbed by the electromagnetic filter plate 42, and then the wastewater is discharged into the inner side of the fixed frame 3 through the second discharge pipe 41, and flows to the top of the sponge layer 32 through the pressing plate 35. At this time, the impurities in the wastewater are further filtered by the sponge layer 32. After filtering, the user starts the electric telescopic rod 34, so that the moving end of the electric telescopic rod 34 drives the pressing plate 35 to move downward, so that the pressing plate 35 presses the sponge layer 32, squeezes out the wastewater in the sponge layer 32, and makes the wastewater flow into the inner side of the sedimentation tank 1 through the first discharge pipe 36;

[0048] After that, the user pours the reagent into the inner side of the sedimentation tank 1, and then starts the second drive motor 26, so that the second drive motor 26 drives the stirring shaft 27 to stir and mix the wastewater inside the sedimentation tank 1, and then the wastewater is precipitated. When the wastewater is precipitated, the user starts the first drive motor 24, so that the first drive motor 24 drives the screw rod 23 to rotate, so that the screw rod 23 is threadedly connected inside the movable plate 25, driving the movable plate 25 to move upward, so that the movable plate 25 drives the fixed rod 28 to move upward, and the fixed rod 28 drives the filter plate 26 to move upward, thereby driving the flocculent to move upward until the filter plate 16 moves to the bottom of the scraper 13, and then the user pulls the pulling plate 15, thereby driving the scraper 13 to move on the top of the filter plate 16 through the pull rod 14, thereby pulling the impurities on the filter plate 16 to the position of the discharge port 11 for discharge, and then the water inside the sedimentation tank 1 is discharged through the valve.

[0049] Compared with related technologies, the circuit board production wastewater treatment device provided by the present invention has the following beneficial effects:

[0050] Through the cooperation of structures such as the sedimentation box 1, the discharge port 11, the scraper 13, the pull rod 14, the pulling plate 15, the filter plate 16, the side plate 2, the chute 21, the slide rod 22, the screw rod 23, the first drive motor 24, the movable plate 25 and the fixed rod 28, when in use, the rotation of the first drive motor 24 can drive the filter plate 16 to move from the inner side of the sedimentation box 1 to the top of the sedimentation box 1, so that the user can clean the flocculants settled inside the sedimentation box 1, thereby facilitating the use of the user, increasing work efficiency and reducing the physical exertion of the staff.

[0056] The working principle of the wastewater treatment device for circuit board production provided by the present invention is as follows:

[0057] After long-term use, when it is necessary to clean the impurities adsorbed by the electromagnetic filter plate 42, the user can push the two push plates 58 toward the middle, so that the two push plates 58 drive the two sliders 56 to move toward the middle, so that the slider 56 drives one end of the push rod 57 to move out from the inner side of the positioning hole 52, and then the user lifts the two push plates 58 upward to remove the electromagnetic filter plate 42 from the inner side of the mounting frame 4, and then the user turns off the power of the electromagnetic filter plate 42 to stop the electromagnetic filter plate 42 from generating magnetic force, so that the impurities on the electromagnetic filter plate 42 fall off.
