Description

Technical Field

[0001] The invention relates to the technical field of impurity removal devices, and in particular to an impurity removal device for making sand from construction solid waste and a construction method thereof. Background Art

[0002] Solid construction waste refers to the slag, abandoned soil, abandoned materials, silt and other wastes generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. The recycling process is to initially clean the construction waste, sort out the recyclable steel and wood, and then crush the bricks and cement concrete blocks into aggregates. After screening, the raw building materials with certain particle size requirements are formed. In the prior art, when sorting the metal fragments such as steel bars mixed in the solid construction waste, the metal fragments can only be taken out manually, and the metal fragments in the bricks or cement concrete can only be removed after the solid construction waste is crushed. A large amount of metal fragments will be mixed in the fragments of the accumulated construction waste. Only the metal fragments on the surface of the construction fragments can be adsorbed by magnetic force. The metal fragments in the garbage fragment pile cannot be adsorbed by magnetic force due to the gravity of the upper fragments, which is not conducive to the recycling of the metal fragments and reduces the recycling efficiency of the metal fragments. Summary of the invention

[0010] Preferably, a feed inlet is provided at the top of the impurity removal housing, and the feed inlet corresponds to the top position of the impurity removal filter.

[0011] A construction method of a construction solid waste sand making device, comprising the above-mentioned construction solid waste sand making device, and the specific operation is as follows:

[0012] When in use, when construction solid waste is crushed into construction debris, the impurity removal filter is used to block metal fragments and larger construction debris, while smaller construction debris pass through the filter holes of the impurity removal filter, and metal fragments and larger construction debris roll into the fixed frame along the inclined surface of the impurity removal filter by gravity, and the metal fragments will be adsorbed on the inclined surfaces of multiple sleeves by magnetic force by the magnet rod, while larger construction debris falls into the external environment along the inclined surfaces of multiple sleeves by gravity, which makes it convenient to remove metal fragments from construction debris and improves the impurity removal effect of construction solid waste after crushing.

[0013] A sleeve is provided on the surface of the magnet rod, and tube covers are threadedly provided at both ends of the sleeve. The two tube covers are movably connected to the inner side of the fixed frame. The sleeve can protect the outside of the magnet rod, reduce the wear of the magnet rod caused by the impact of gravel and metal fragments, and protect the magnet rod.

[0014] The two symmetrical inner sides of the fixed frame are both embedded with multiple first fixed shafts and worms through bearings, and one ends of the multiple first fixed shafts and worms are respectively installed on the ends of the multiple pipe covers through screws, and a driving mechanism is connected between the multiple worms. The driving mechanism includes a rotating shaft, and both ends of the rotating shaft are installed at the bottom of the fixed frame through bearing seats. A fixed sleeve on the surface of the rotating shaft is provided with multiple worm gears, and the multiple worm gears are respectively engaged with the multiple worms. One end of the rotating shaft is connected to a driving motor through a coupling. When the driving motor is energized, it drives the rotating shaft to rotate, and the rotating shaft drives the multiple worm gears to rotate. The multiple worm gears drive the multiple worms to rotate, and the multiple worms drive the multiple sleeves to rotate through the pipe covers. The metal scraps are brought into contact with the scraper through the rotation of the sleeve, so that the scraper can clean the metal scraps adsorbed on the sleeve conveniently.

[0015] A scraper is provided at the bottom of the sleeve. As the sleeve rotates, the metal scraps magnetically attracted by the magnet bar on the sleeve surface rotate synchronously. After the metal scraps rotate to the position corresponding to the scraper, the metal scraps will be blocked by the scraper. As the sleeve continues to rotate, the metal scraps fall off the sleeve due to the obstruction of the scraper, which facilitates the removal of the metal scraps on the sleeve and allows the sleeve to leave more vacant parts for contacting the metal scraps.

[0016] A mounting rod is installed at the bottom of the scraper by screws, and a fixed pipe fitting is movably provided at the bottom end of the mounting rod, and a compression spring is movably provided between the fixed pipe fitting and the surface of the mounting rod, and both ends of the compression spring are respectively installed at the top end of the mounting rod and the bottom end of the fixed pipe fitting by screws. The top of the scraper contacts the bottom of the sleeve, and the compression spring supports the scraper by its own elastic potential energy, so that the top of the scraper can contact the bottom of the sleeve, and the setting of the fixed pipe fitting and the mounting rod prevents the scraper from being displaced by the position when the sleeve rotates, thereby improving the stability of the scraper.

[0017] A discharge plate is installed through the side of the debris removal shell, and the discharge plate is arranged obliquely below the debris removal filter. The discharge plate is used to receive smaller building debris that fall from the debris removal filter. At the same time, a second opening for the discharge plate to pass through is opened on the side of the debris removal shell, and the discharge plate is arranged obliquely to facilitate the building debris to roll on the discharge plate to the external environment by gravity.

[0018] A feed inlet is provided at the top of the impurity removal shell, and the feed inlet corresponds to the top position of the impurity removal filter. The feed inlet can allow crushed construction solid waste to fall onto the impurity removal filter.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This solution sets up a debris removal filter to perform initial filtering on the crushed building debris, blocking the metal fragments and larger-sized building debris in the building debris at the top of the debris removal filter, while the metal fragments and larger-sized building debris roll into the fixed frame, and the metal fragments will be adsorbed by the multiple magnet bars in the fixed frame, while the larger-sized metal fragments will roll along the surface of the multiple magnet bars into the external environment, making it convenient to remove the metal debris in the building debris.

[0030] The surface of the magnet rod 13 is sleeved with a sleeve 8, and both ends of the sleeve 8 are threadedly sleeved with pipe covers 12.
