Example 1
The present embodiment provides a concrete aggregate screening machine of different gradation, which includes a screening box 1 and legs 2, as shown in fig. 1.
Specifically, screening case 1 is rectangle box structure, and top one side of screening case 1 is equipped with the feeder hopper 3 with the inside intercommunication of screening case 1, and the outside fixed mounting of screening case 1 has vibrator 4, is equipped with four layers of sieve 5 in the screening case 1. The supporting leg 2 is of an I-shaped frame structure, and the supporting leg 2 is fixedly connected with four corners at the bottom of the screening box 1 through springs 9.
The specific arrangement of the four layers of sieve plates 5 is shown in fig. 2-3, and the four layers of sieve plates 5 divide the interior of the sieving box 1 into four sieving layers; four layers of sieve 5 are in screening 1 inside by the high to low slope setting, and are parallel to each other, sieve 5 and 1 inner wall fixed connection of screening case, and every layer of sieve 5's high point end all is located feeder hopper 3 below, and every layer of sieve 5's the equal fixedly connected with in low point end crosses the blown down tank 6 that sieves 1 lateral wall of separation case. As shown in fig. 3, the sieve plates 5 are provided with sieve holes 7, the aperture of the sieve hole 7 of each layer of sieve plate 5 arranged from high to low is gradually reduced, and the sieve plate 5 at the lowest position has no sieve hole 7; the sieve plate 5 is also provided with triangular baffles 8 which are arranged in a staggered manner.
The working principle of the concrete aggregate screening machine with different gradation is as follows:
firstly, starting a vibrating machine 4, wherein the vibrating machine 4 is matched with a spring 9 between a supporting leg 2 and a screening box 1 to enable the screening box 1 to generate elastic vibration; at this moment, can pour into the concrete aggregate in to screening case 1 through feeder hopper 3, when screening case 1 vibrates, screening case 1 is inside to the four layers of sieve 5 screening concrete aggregate that sets up by the height. Specifically, if the particle diameter of the concrete aggregate is larger than the aperture of the sieve pore 7 of the first-layer sieve plate 5, the concrete aggregate stays on the first-layer sieve plate 5, is vibrated by the sieve box 1 and moves from the high-point end of the sieve plate 5 to the low-point end of the sieve plate 5, and finally is discharged out of the sieve box 1 through the discharge chute 6; if the particle diameter of the concrete aggregate is smaller than the aperture of the sieve pore 7 of the first-layer sieve plate 5, the concrete aggregate enters the next sieve layer through the sieve pore 7 of the first-layer sieve plate 5 and is sieved by the lower-layer sieve plate 5. Because the aperture of the sieve pore 7 of the four layers of sieve plates 5 arranged from high to low is gradually reduced, the sieve plate 5 positioned at the lowest position has no sieve pore 7, and then the concrete aggregate with different particle diameters can be screened at the same time, and the screening efficiency is improved. In addition, because triangular baffle plates 8 are arranged on the sieve plates 5 in an staggered mode, the triangular baffle plates 8 prolong the retention time of concrete aggregate on the sieve plates 5, and the sieving precision of each layer of sieve plates 5 can be further improved.
