Problems solved by technology

[0002] During the detection of electrical equipment, the detection equipment will emit high-intensity electromagnetic waves. If the substance in the concrete floor is an independent metal substance (electrically called suspension potential), it will be absorbed by the suspension potential. For a long time, The suspension potential will absorb more and more until it is saturated. During the detection of electrical equipment, the saturated suspension potential will release the absorbed electromagnetic waves. At this time, the detection equipment...

Abstract

The invention discloses a deironing filter of a concrete blender and relates to a construction plant of electrical equipment detection center indoor shielding ground concrete with a large-power power station serving as a core. The deironing filter comprises a neodymium iron boron magnet, a rectangular supporting frame, a nut, a shock absorber, angle iron, a flat vibration device, round bar steel and rubber leathers. In a using process, the flat vibration device is opened, materials self fall into a material receiving hopper, and the deironing filter enables metallics in macadam, sand and cement to be effectively absorbed and guarantees quality of shielding concrete.

Example Embodiment

[0012] The present invention will be described below in conjunction with specific embodiments.
[0013] in figure 1 Among them, 8# channel steel is made into a rectangular support frame with a cross-sectional size of 1230*1030, that is, the cross-sectional size of the discharge port is 400+300*2 (the actual size can be determined according to the power of the discharge machine) + two flat steel size 12mm+ The size of the two shock absorber rods is 8mm + installation error 10mm. Then use angle steel as a column to weld the support frame to the receiving opening. The support frame is 355mm higher than the upper opening of the receiving opening, that is, the base of the flat vibrator is 200mm + the size of the shock absorber is 150mm + the gap is 5mm.
[0014] Use 6# flat steel to make a rectangular frame with a side length of 1200*1000*200 (height), and then use Φ12 round steel with both ends of the wire in the middle of the frame to arrange the neodymium iron boron magnets at a vertical spacing of 100mm and a horizontal spacing of 45mm. The spacing is the best spacing obtained after many tests based on the iron absorption stone. The control method: cut the Φ20 galvanized steel pipe 4, the middle length is 45mm, the length of both ends is 27.5mm, and finally the plate vibrator is welded to the upper side of the frame . The function of the plate vibrator is to prevent sand and gravel from falling into the hopper quickly when passing through the iron removal part.
[0015] in figure 2 In the process, use a shock absorber to weld the support frame part and the iron removal part, and then use a soft rubber to seal the remaining 240mm ((1500-1020)/2) between the hopper and the iron removal filter. Just disconnect.
