Description

Technical Field

[0001] The utility model relates to the technical field of heavy metal wastewater treatment, in particular to an integrated device for treating organic wastewater containing heavy metals. Background Art

[0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged from industrial production processes such as mining, machinery manufacturing, chemical engineering, electronics, and instrumentation. Heavy metal wastewater (such as those containing cadmium, nickel, mercury, and zinc) is one of the most serious industrial wastewaters that pollutes the environment and poses the greatest harm to humans. Its water quality and quantity are closely related to production processes.

[0003] At present, the precipitation method is mainly used to treat heavy metal wastewater. It mainly separates the heavy metals in the water from the water in the form of precipitation by adding various agents, such as flocculants, and then filters them through a filter to complete the removal of the heavy metals. However, during precipitation, the amount of flocculant added is difficult to control, resulting in the problem of too much or too little flocculant. Too much flocculant is likely to contaminate the wastewater again, while too little flocculant cannot completely remove the heavy metals in the heavy metal wastewater. For this reason, those skilled in the art have proposed an integrated device for treating organic wastewater containing heavy metals to solve the problems raised in the above background. Utility Model Content

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] See also Figures 1-4 , an integrated device for treating organic heavy metal-containing wastewater, comprising a box body 1; a water inlet pipe 2 is provided on one side of the top of the box body 1, a drain pipe 3 is provided on one side of the bottom of the box body 1, a liquid storage chamber 7 is provided on the other side of the top of the box body 1, the liquid storage chamber 7 is used to store flocculant, a liquid adding pipe 8 is provided on the liquid storage chamber 7, a drain pipe 9 extending into the interior of the box body 1 is provided at the bottom of the liquid storage chamber 7, a movable plate 13 is slidably provided in the drain pipe 9, a communication port 14 is provided on the movable plate 13, the size of the communication port 14 is the same as the inner diameter of the drain pipe 9, and further comprising:

[0023] A driving component is provided on one side of the water inlet pipe 2 and is activated by the flow of the falling heavy metal wastewater;

[0024] A swinging member, which is arranged outside the water inlet pipe 2 and is used to drive the movable plate 13 to swing;

[0025] A stirring component is provided in the box 1 and is used to stir and mix the injected heavy metal wastewater and flocculant;

[0026] A reset component is provided on the drain pipe 9 and is used to reset the movable plate 13 .

[0027] The heavy metal wastewater is poured into the box body 1 through the water inlet pipe 2. Under the impact force of the wastewater flowing downward, the driving component will be started, and the driving component will drive the swinging component connected to it to swing back and forth left and right, so that the movable plate 13 can move back and forth left and right, and the connecting port 14 on the reciprocating plate will be intermittently connected with the drain pipe 9, so that the flocculant in the liquid storage chamber 7 can be intermittently discharged from the drain pipe 9 into the bottom of the box body 1, and under the action of the stirring component, it is stirred, mixed and precipitated with the discharged heavy metal wastewater, so that the amount of flocculant discharged from the drain pipe 9 into the bottom of the box body 1 can be adjusted according to the inflow of heavy metal wastewater, thereby avoiding excessive or insufficient inflow of flocculant to affect the treatment effect of heavy metal wastewater. In addition, when the water inlet pipe 2 stops introducing heavy metal wastewater, the reset component will reset the movable plate 13, so that the movable plate 13 blocks the drain pipe 9.

[0028] In one case of this embodiment, the driving component includes a rotating shaft 4 rotatably arranged on one side of the water inlet pipe 2, a rotating column 11 is installed on the rotating shaft 4, and a plurality of impact plates 6 distributed in an annular manner are installed on the outer wall of the rotating column 11.

[0029] The heavy metal wastewater is pumped into the water inlet pipe 2 by a water pump and flows into the bottom of the box body 1 through the water inlet pipe 2. In the process of the heavy metal wastewater flowing downward along the water inlet pipe 2, the heavy metal wastewater will continuously impact the impact plate 6, thereby driving the impact plate 6 to rotate around the rotating column 11, causing the rotating shaft 4 to rotate, thereby driving the swinging component to drive the movable component to move back and forth left and right, so that the connecting port 14 on the movable plate 13 is intermittently connected with the drain pipe 9, so that the flocculant in the liquid storage chamber 7 can be intermittently discharged into the box body 1 and mixed with the heavy metal wastewater, so that the drain pipe 9 can be opened to discharge a certain amount of flocculant after the heavy metal wastewater impacts the impact plate 6 and drives the rotating shaft 4 to rotate a certain angle, that is, after a certain amount of heavy metal wastewater is discharged, the drain pipe 9 also discharges a certain amount of flocculant, so that the amount of flocculant discharged into the bottom of the box body 1 by the drain pipe 9 can be adjusted according to the inflow of heavy metal wastewater.

[0030] In one case of this embodiment, the swinging component includes a turntable 10 installed on one end of the rotating shaft 4 passing through the water inlet pipe 2, and a rotating column 11 is installed at the eccentric point of the turntable 10. Fixed cylinders 15 are installed on both sides of the discharge pipe 9. The fixed cylinders 15 are slidably connected to the limit rod 16, and the limit rod 16 is fixedly connected to the swing rod frame 12. The swing rod frame 12 is slidably connected to the rotating column 11.

[0031] When the rotating shaft 4 on the driving component rotates, it will drive the turntable 10 to rotate, so that the rotating column 11 on the turntable 10 rotates, and the swing arm frame 12 cooperates with it and cooperates with the fixed cylinder 15 and the limit rod 16 to drive the movable plate 13 to move back and forth left and right. When the movable plate 13 moves to the rightmost end, the movable plate 13 will block the drain pipe 9, and when the movable plate 13 moves to the leftmost end, the connecting port 14 will be completely connected with the drain pipe 9, so that the flocculant in the liquid storage chamber 7 can flow from the drain pipe 9 to the bottom of the box body 1, thereby realizing intermittent discharge.

[0032] In one aspect of this embodiment, the reset component includes an electromagnet 21 mounted on the side wall of the discharge pipe 9 , and a permanent magnet 20 is provided at the end of the limit rod 16 away from the swing rod frame 12 .

[0033] When the water inlet pipe 2 no longer needs to flow into heavy metal wastewater, the water pump is stopped. At this time, there is no wastewater impacting the impact plate 6. In order to make the movable plate 13 block the drain pipe 9, the electromagnet 21 can be energized to generate magnetism. The magnetism of the electromagnet 21 is the same as that of the near end of the permanent magnet 20, thereby generating repulsion, so that the movable plate 13 moves to the rightmost end and blocks the drain pipe 9, which has a better effect.

[0034] In one case of this embodiment, the stirring component includes a stirring shaft 18 rotatably arranged at the bottom of the box body 1, a stirring rod 19 is installed on the stirring shaft 18, and a motor 17 connected to the stirring shaft 18 is installed at the bottom of the box body 1.

[0035] By starting the motor 17 and driving the stirring shaft 18 to rotate, the stirring rod 19 can stir the heavy metal wastewater and the flocculant evenly, so that the flocculant can fully contact the heavy metals in the heavy metal wastewater, resulting in a better precipitation effect.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
