Description
Technical Field
The invention relates to the technical field of sand making equipment, in particular to a screen cleaner for automatically cleaning a screen of a vibrating screen.
Background
The high-rise building is raised around our body at a high speed, so that people can feel no more than exclamation. In recent years, the buildings in the city are built at four places, the places are modern reinforced cement and the figure of the road, and all the places cannot leave the sandstone for the construction engineering. The sandstone plays a role of aggregate in the building, but with the wide application of commercial concrete and mortar, the natural sand resource is in more and more shortage, and the natural sand is also made up by artificial sand. The sand screening equipment is an important component of machine-made sand equipment. The sand screening equipment of the sand making equipment on the market at present mainly takes a vibrating screen as a main part, and has the advantages of high screening efficiency, easy screen replacement, long material movement track and high screen surface utilization rate.
The working principle of the vibrating screen is that when the vibrating screen works, the motion trail of any point on the screen box is a straight line, namely when the eccentric block rotates, a force is generated on one aspect, and no couple exists, so that the vibrating screen only makes a reciprocating plane straight line along the direction. The rotary vibration sieve is characterized in that a heavy hammer (unbalanced hammer) is vertically arranged on a motor shaft, the rotary motion of the motor is converted into horizontal, vertical and inclined three-dimensional motion, and the motion is transmitted to a sieve surface, so that materials are subjected to outward-expanding involute motion on the sieve surface, and the vibration sieve is called as a rotary vibration sieve.
However, in the actual use process, due to different water content of raw materials, screen mesh holes on the vibrating screen can be slowly stuck by powder or blocked by particle objects to cause the low efficiency of the vibrating screen along with the long service life of the vibrating screen, and the gradation of the produced sand is also changed. At present, the screen is generally cleaned manually at regular intervals, so that the labor intensity is increased, and the production efficiency is influenced. At this time, an automatic screen cleaner is needed to automatically clean the powder or particle objects blocked by the screen mesh.
Disclosure of Invention
In order to solve the technical problems, the invention is realized by the following technical scheme:
a screen cleaner for automatically cleaning a screen of a vibrating screen comprises a motor, a transmission shaft and a rotary table, wherein the transmission shaft is horizontally arranged below the screen of the vibrating screen, two ends of the transmission shaft are fixed on a rack of the vibrating screen through bearing seats, the transmission shaft is of a hollow structure, the upper side surface and the lower side surface of the transmission shaft are respectively provided with a radial strip-shaped guide groove, and the guide grooves penetrate into the transmission shaft; an output shaft of the motor is connected with one end of a transmission shaft through a transmission belt, the other end of the transmission shaft is provided with a cylinder, a bearing is fixedly mounted at the end part of a piston rod of the cylinder, and the bearing can reciprocate in the transmission shaft; a through hole is formed in the middle of the rotary table, the rotary table is sleeved in the transmission shaft through the through hole, the inner side wall of the through hole is fixedly connected with the outer ring of the bearing through a connecting block, and the connecting block is positioned in the guide groove; impact balls are uniformly arranged on the edge of the turntable; the front end face of the piston rod is provided with a high-pressure air nozzle, an air outlet of the high-pressure air nozzle points to the screen, and the high-pressure air nozzle is connected with external air supply equipment through a pipeline.
The general idea of the invention is as follows: through the screen cloth below installation carousel at the shale shaker, the continuous screen cloth of hitting ball on the carousel, granule object and bonding powder in the screen cloth punchhole receive to hit and to beat the screen cloth and can break away from the punchhole under the condition, thereby reach the effect of automatic clearance screen cloth, set up high pressure air cock simultaneously and can make and blow to the screen cloth when hitting the screen cloth at the ball impact, accelerate the clearance speed of powder and granule object on the punchhole and break away from the screen cloth fast and avoid the secondary to fall into the punchhole.
In addition, the invention also provides the following auxiliary technical scheme:
furthermore, the impact ball is connected with the turntable through a chain. When need not clear up the screen cloth like this, the carousel is out of work, and the impact ball hangs on the carousel under the dead weight effect, avoids influencing the life of automatic screen cleaner because of the long-time vibration of shale shaker, and when the carousel rotated, the impact ball flies to get rid of and hits the screen cloth under the centrifugal force effect.
Further, the contact area of the impact ball when the impact ball collides with the screen is 1/4-1/2. The applicant verifies through a plurality of experiments that the effect of clearing the screen blockage is best under the condition that the spherical surface of 1/4-1/2 is contacted with the screen when the impact ball hits the screen; the contact area between the impact ball and the screen is too small to achieve the effect of cleaning the screen blockage, and the contact area between the impact ball and the screen is too large, so that adverse effects can be caused on the screen in the impact process.
Furthermore, the side surface of the transmission shaft is uniformly distributed with vent holes. The purpose of arranging the air vent can keep balance in the rotating process of the turntable.
Furthermore, the number of the impact balls is 2-6.
Furthermore, a speed regulating valve is installed on a connector of the air cylinder, and the movement speed of a piston rod of the air cylinder is 5-10 cm/s. The speed of the piston rod of the air cylinder is adjusted by the speed adjusting valve, and the turntable moves back and forth at a constant speed according to the specified speed.
Further, the transmission belt is a flat belt, a triangular belt or a toothed belt.
Further, the impact ball is a rubber ball or a steel ball.
Compared with the prior art, the invention has the beneficial effects that:
the automatic screen cleaner has simple and reasonable structural design and easy processing and manufacturing, can clean the screen by starting the automatic screen cleaner under the condition of no shutdown of the vibrating screen, does not influence the production efficiency, and can reduce the labor intensity of workers; meanwhile, an air cylinder is designed on one side of the transmission shaft, and a piston rod of the air cylinder drives the rotary table to do radial uniform reciprocating motion in a guide groove of the transmission shaft, so that cleaning along the radial direction of the transmission shaft can be realized, and the effect of cleaning the screen of the automatic screen cleaner disclosed by the invention is optimal.
