[0031] A method for using a construction wastewater and construction waste recycling device, the method comprising the following steps:

[0032] Step 1: inject an appropriate amount of construction wastewater mixed with construction waste into the first box 1 from the feed inlet 3;

[0033] Step 2: Start the first motor 801 until the first driving mechanism 8 drives the screening mechanism 7 to complete the filtration and screening of the construction wastewater. After a period of time, under the action of the first driving mechanism 8, the filter residue enters the second box 9;

[0034] Step 3: Turn off the first motor 801;

[0035] Step 4: Discharge the filtered water from the first box 1 through the liquid outlet 5;

[0036] Step 5: Start the second motor 1202 and turn on the switch of the control electromagnet 14. The second motor 1202 drives the stirring mechanism 11 to operate, and the filter residue is stirred and turned up. After it contacts the magnetic second box door 13, the iron products are attracted.

[0039] Working principle: When the present invention is in use, after injecting an appropriate amount of construction wastewater into the first box body 1 from the feed port 3, the first motor 801 can be started. Driven by the first motor 801, the sliding rod 802 in the driving mechanism 8 is driven by the crank 812, and the slider 809 installed on the sliding rod 802 reciprocates in the vertical direction in the stepped groove 808, and causes the sieve plate 701 to reciprocate around its hinge point. In this way, the sieve plate 701 completes the screening and filtration of the construction wastewater, and the filter residue moves toward the discharge port 4 and finally enters the first box body 1. In the second box body 9, when the filter residue completely enters the second box body 9, the first motor 801 can be turned off, and the second motor 1202 and the electromagnet 14 can be started. Driven by the second motor 1202, the stirring mechanism 11 operates, and under the rotation of the spiral blade 1102, the filter residue is stirred and turned over. When it comes into contact with the second box door 13 which is already magnetic, the iron products therein are adsorbed onto the second box door 13. After a period of time, the second motor 1202 is turned off, and after opening the second box door 13, the electromagnet 14 is turned off, and the iron products in the wastewater can be collected.
