Description

Technical Field

[0001] The present invention relates to the technical field of wastewater purification, and in particular to a device and method for purifying construction wastewater. Background Art

[0002] Construction site wastewater refers to various wastewater generated in construction and civil engineering related construction activities. This type of wastewater contains soil, sand, concrete residues, oil, chemicals, heavy metals, paint and other construction material residues. If it is discharged directly without treatment, it will cause serious pollution to the environment, including water quality deterioration, soil pollution and ecosystem damage. In order to prevent these pollutants from entering the water body and affecting the environment and human health, appropriate professional wastewater purification equipment must be used for treatment. Generally, various methods such as biological treatment, chemical treatment and physical treatment are used for comprehensive treatment to ensure that the wastewater is fully purified and will not have a negative impact on the surrounding environment. Filters are usually used for filtration.

[0003] In the existing patent CN221254340U, a pulp wastewater purification device is disclosed, including a box body, a mounting plate is fixedly welded on the upper end of the box body, the upper end of the mounting plate is open, and a positioning plate is fixedly welded on the inner wall of the mounting plate. The utility model supports and connects the filter screen cover through a cylinder frame and is installed inside the mounting plate as a whole. The cylindrical filter screen cover has a larger filtering area. When the wastewater is introduced into the filter screen cover, the inclined filter screen cover concentrates the bottom end of the filtered large particle suspension, and the motor drives the driving gear to rotate, thereby driving the matching meshing gear ring, so that the cylinder frame and the filter screen cover rotate as a whole, so that the rolling filter screen cover performs all-round filtering, and at the same time avoids large particle suspensions from blocking the filter mesh holes on a single side. The rotating filter screen cover allows the upper filtered suspended matter to roll and gather at the bottom, which is convenient for concentration. The filter screen cover at a higher position can cooperate with gravity for rapid filtering.

[0004] In the above structure, the filter can be used for filtering, but after being used for a long time, the filter will become clogged and need to be disassembled. However, when disassembling, the device needs to be shut down, and then the staff will disassemble and replace the filter. Periodic shutdown is required, and the filter cannot be replaced during the operation of the equipment, which is not conducive to the continuous filtration of the wastewater. The wastewater to be filtered has to wait for a long time, which makes the filter more easily clogged, reducing the filtration efficiency, which is not conducive to the device's treatment of wastewater, and the filtration process is seriously affected, increasing the company's production costs.

[0060] Embodiment three:

[0061] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the present invention proposes a method for purifying construction wastewater. The device is connected to the construction wastewater source through the input pipe 3, so that the wastewater is continuously passed into the filter water tank 2. The wastewater in the filter water tank 2 is filtered out by the arc filter screen 606 on the filter assembly 6, so that the water enters the receiving water tank 1, and the filtered water is centrally processed through the output pipe 4, while the filter residue remains on the arc filter screen 606;

[0062] At this time, the squeezing plate 803 contacts the working arc filter screen 606, and the driving mechanism 7 is started. Under the action of the movable component 10, the squeezing component 8 is forced to squeeze the filter residue on the working arc filter screen 606, so that the filter residue is concentrated at the conveying component 11. When the filter residue reaches a certain level, the conveying component 11 is started, so that the filter residue is continuously output to the outside of the filter water tank 2 for centralized treatment;

[0063] Since the squeeze plate 803 separates the filter water tank 2, when the filter residue is processed, the squeeze plate 803 returns to its original position. At this time, the rotating mechanism 5 is started to drive the filter water tank 2 to rotate. Under the action of the transmission component 9, the movable component 10 drives the squeeze plate 803 to move on the slider 801, so that the squeeze plate 803 is separated from the arc filter screen 606, and the waste water is passed into various places of the filter water tank 2. Then, the squeeze plate 803 is restored to its original position, and the filter water tank 2 is shaken to quickly filter the water in the filter residue.

[0064] When the working arc filter 606 is blocked, it is necessary to disassemble the working arc filter 606, start the rotating mechanism 5 to drive the filtered water tank 2 to rotate at a right angle, and under the action of the transmission component 9, the movable component 10 drives the extrusion plate 803 to move on the slider 801 until the two arc filter screens 606 exchange working states and positions, so that the idle extrusion plate 803 and the idle arc filter screen 606 rotate at a right angle and contact to form a working state, and the working extrusion plate 803 and the working arc filter screen 606 rotate at a right angle and separate to form an idle state, and the working arc filter screen 606 is replaced to achieve continuous filtration.

[0065] Working principle: The device is connected to the construction wastewater source through the input pipe 3, so that the wastewater is continuously passed into the filter water tank 2, and the wastewater in the filter water tank 2 is filtered out by the arc filter screen 606 on the filter assembly 6, so that the water enters the receiving water tank 1, and the filtered water is centrally processed through the output pipe 4, while the filter residue remains on the arc filter screen 606;

[0066] At this time, the squeezing plate 803 contacts the working arc filter screen 606, and the driving mechanism 7 is started. Under the action of the movable component 10, the squeezing component 8 is forced to squeeze the filter residue on the working arc filter screen 606, so that the filter residue is concentrated at the conveying component 11. When the filter residue reaches a certain level, the conveying component 11 is started, so that the filter residue is continuously output to the outside of the filter water tank 2 for centralized treatment;

[0067] Since the squeeze plate 803 separates the filter water tank 2, when the filter residue is processed, the squeeze plate 803 returns to its original position. At this time, the rotating mechanism 5 is started to drive the filter water tank 2 to rotate. Under the action of the transmission component 9, the movable component 10 drives the squeeze plate 803 to move on the slider 801, so that the squeeze plate 803 is separated from the arc filter screen 606, and the waste water is passed into various places of the filter water tank 2. Then, the squeeze plate 803 is restored to its original position, and the filter water tank 2 is shaken to quickly filter the water in the filter residue.

[0068] When the working arc filter 606 is blocked, it is necessary to disassemble the working arc filter 606, start the rotating mechanism 5 to drive the filtered water tank 2 to rotate at a right angle, and under the action of the transmission component 9, the movable component 10 drives the extrusion plate 803 to move on the slider 801 until the two arc filter screens 606 exchange working states and positions, so that the idle extrusion plate 803 and the idle arc filter screen 606 rotate at a right angle and contact to form a working state, and the working extrusion plate 803 and the working arc filter screen 606 rotate at a right angle and separate to form an idle state, and the working arc filter screen 606 is replaced to achieve continuous filtration.
