the sand and stone circulating assembly comprises a conveying platform 21 and a plurality of circulating material lifting plates 22 which are vertically arranged; a plurality of bosses 21a are arranged on the conveying platform 21 at equal intervals; each of the circulating material lifting plates 22 is hinged to one of the bosses 21a through a torsion spring, and the storage surface of each circulating material lifting plate 22 is perpendicular to the surface of the conveying platform 21 at the respective installation position.
In practice, the transfer platform 21 consists of two driving rollers and a conveying belt; the circulating material lifting plate 22 is driven by the conveying platform 21 to pass through the coarse sand outlet and reach the sand inlet at the top of the machine body 1.
In this way, the circulating material lifting plate 22 can receive coarse sand leaked from the coarse sand outlet and convey the coarse sand to a sand inlet at the top of the machine for secondary fine crushing.
Compared with the prior art, the dust-settling and sand-falling machine has the advantages that:
the sand and stone circulating component arranged on the machine body 1 can be used for carrying out secondary fine crushing on sand and stone which still do not meet the use standard after primary fine crushing; when the relatively coarse sand and stone after the first fine crushing fall into the circulating material lifting plate 22 along the coarse sand filter screen 11, the circulating material lifting plate 22 pours the coarse sand and stone into the machine body 1 again from the top of the machine; the manual sieving is not needed for pouring again, so that the time and the labor are saved.
Above-mentioned dust fall shakeout machine has simple structure, easy to carry out's advantage, is fit for installing and using at current foundry, and the cost of operation use is lower, can improve and make the benefit that rises.
Wherein, the top edge of the machine body 1 is fixedly connected with a feeding component communicated with a sand inlet;
the feeding assembly comprises a feeding plate 31 and a feeding roller 32; one end of the feeding plate 31 is fixedly connected with the top edge of the machine body 1 at a position corresponding to the circulating material lifting plate 22; the feed roller 32 is horizontally and rotatably connected to the other end of the feed plate 31, and the position of the feed roller 32 is in the ascending track of the circulating material lifting plate 22.
In practice, the feeding plate 31 is communicated with the sand inlet, and the sand brought by the feeding roller 32 can be guided into the machine body 1 by the feeding plate 31.
Therefore, when the circulating material lifting plate 22 reaches the sand inlet in the lifting process, the circulating material lifting plate 22 is in contact with the feeding roller 32, and at the moment, if the circulating material lifting plate 22 continues to ascend, the circulating material lifting plate 22 rotates and inclines clockwise around the boss 21a under the blocking of the feeding roller 32, and the sand on the circulating material lifting plate 22 slides to the feeding roller 32 due to the inclination; because of the action of the torsion spring, a certain positive pressure and friction force exist between the circulating material lifting plate 22 and the feeding roller 32, and the feeding roller 32 is a rotatable component, so that the circulating material lifting plate 22 can drive the feeding roller 32 to rotate through the friction force when ascending, and the feeding roller 32 rotates to carry the sliding sand to the feeding plate 31.
Compared with the method of directly blocking the blanking by using the feeding plate 31, the method for blocking the blanking by using the feeding roller 32 has the advantages that:
if only the feeding plate 31 is adopted, the feeding plate 31 needs to be an inclined plate, so that the falling gravels can enter the machine body 1 along the feeding plate 31, the circulating material lifting plate 22 rises in a parallel posture, so that the circulating material lifting plate 22 and the feeding plate 31 can form a blanking dead angle when the circulating material lifting plate and the feeding plate start to contact, the gravels falling into the blanking dead angle cannot enter the feeding plate 31, although the blanking dead angle can be reduced along with the lifting of the circulating material lifting plate 22, the gravels falling into the blanking dead angle can also form a certain thickness between the circulating material lifting plate 22 and the feeding plate 31, and the blanking dead angle is closed after delay, so that the blanking efficiency is low;
if the feeding roller 32 is adopted, the sand which is originally positioned at the blanking dead angle can be driven to the feeding plate 31 by the rotation of the feeding roller 32, and the blanking efficiency is improved.
A plurality of first convex lines 41 are arranged on the feeding surface of the feeding roller 32 at intervals along the circumferential direction of the feeding roller 32.
Thus, the lifting force of the feeding roller 32 to the sand in the blanking dead space during feeding is enhanced, and the friction force between the feeding roller 32 and the circulating material lifting plate 22 is increased.
A plurality of second convex lines 42 are arranged on the object placing surface of the circulating material lifting plate 22 at intervals corresponding to the position of the feeding roller 32.
Thus, the probability of sand falling from the blanking dead angle is reduced, and the friction force between the feeding roller 32 and the circulating material lifting plate 22 is further increased
The first convex lines 41 and the second convex lines 42 have the same structure; the first convex line strips 41 and the second convex line strips 42 are both straight line strips.
In practice, the second convex line 42 and the first convex line 41 are arranged in parallel with each other.
Thus, the mutually matched transmission between the first convex line 41 and the second convex line 42 can more easily transmit sand to the material conveying plate 31, and the stability of transmitting sand is improved.
Wherein, also include drive shaft 51 and sand roller 52; the transmission shaft 51 is penetratingly arranged on the side wall of the machine body 1; one end of the transmission shaft 51 outside the machine body 1 is in transmission connection with a driving motor arranged outside the machine body 1 through a transmission belt, the sand grinding roller 52 is rotatably installed in the machine body 1, and the sand grinding roller 52 is in transmission connection with one end of the transmission shaft 51 inside the machine body 1.
In practice, the sand roller 52 is used for finely crushing the sand by cooperating with a grinding table fixedly connected to the inner side wall of the machine body 1, and the distance between the surface of the sand roller 52 and the surface of the grinding table is not more than 3 mm.
Wherein, a liquid channel 61 is arranged in the sand grinding roller 52; the grinding surface of the sand grinding roller 52 is provided with a plurality of liquid guide holes 62, and each liquid guide hole 62 is communicated with the liquid channel 61.
Thus, the sand grinding roller 52 can humidify the sand by injecting water to the sand during grinding, thereby reducing dust generated during discharging of the sand.
The liquid channel 61 is connected with an output port of the water pump 7 through a water delivery pipe, and an input port of the water pump 7 is connected with a water source filled with reclaimed water through a pipeline.
In this way, the liquid passage 61 can obtain a continuous supply of water, and the degree of humidification can be adjusted by controlling the water pump 7.
Wherein, a single liquid guide film 63 is arranged at the outlet of each liquid guide hole 62.
In this way, sand is only present on the surface of the sand roller 52 and does not enter the drain hole 62 to cause blockage, and the sand on the surface of the sand roller 52 is better cleaned.
Wherein, also comprises a shakeout room 8; a sand outlet is formed in the bottom of the machine body 1 and penetrates into the shakeout room 8; a plurality of water sprinklers 81 are arranged on the inner wall of the shakeout room 8; each sprinkler 81 is connected with the output port of the water pump 7 through a water delivery pipe.
In implementation, the machine body 1 is installed in a wall body in a penetrating mode, and the shakeout room 8 is arranged at the lowest part of the wall body.
