Technical Field
The invention belongs to the field of vibrating screening machinery, and mainly relates to a large inclined screen surface projection penetrating linear screen which is provided with two vibrators and is provided with a crossbeam, and the exciting force of the large inclined screen surface projection penetrating linear screen is vertical to a screen surface.
Background
The existing grading sieve with the inclined sieve surface has the advantages that the movement track adopts a circular track, the vibration exciter adopts a single-shaft structure and a double-shaft structure to be arranged more, the vibration parameters are generally small, the inclined sieve surface grading sieve with the structure is frequently blocked in holes when difficult-to-sieve materials and fine particle materials are processed, and the sieving rate is low. In addition, due to the centralized arrangement and installation of the vibrators and the small number of bearings, the whole screening machine is weak in rigidity, the bearings are more in heating damage, and the screening machine cannot be designed in a large scale. The chinese patent office discloses a patent application of "large linear vibrating screen", because the screen surface of the linear vibrating screen is horizontally arranged and the mounting plane of the vibrator forms a certain angle with the screen surface, the resultant force of vibration forming a certain angle with the screen surface is not beneficial to the screen surface. The material difficult to screen is more adverse, and the improvement of the screening efficiency is directly influenced. In addition, two sets of a plurality of biax vibrators are arranged on a mounting beam in parallel, although the intensity of vibration of shale shaker has been increased, because the vibrational force of high strength concentrates on acting on the reel, greatly reduced the life-span of reel, be unfavorable for the large-scale development of shale shaker.
Disclosure of Invention
The invention aims to provide a large inclined screen surface projection penetration linear screen which has the advantages of large exciting force, strong bearing capacity, uniform stress of a screen frame, convenience for large-scale development of screening area and good screening penetration performance.
The invention is realized by the following technical scheme, which comprises a screen frame, a screen surface, a box type gear forced vibrator, a vibrator mounting girder, a vibration damping supporting device and a motor transmission device, and is characterized in that: two vibrator mounting girders are mounted above the screen frame in parallel and symmetrically arranged on two sides of the gravity center G of the screen frame; a vibrator mounting plane on the vibrator mounting crossbeam is parallel to the screen surface, a box-type gear forced vibrator group is mounted on the vibrator mounting plane of each vibrator mounting crossbeam, and each box-type gear forced vibrator group is formed by mounting 2-4 box-type gear forced vibrators in series; the box-type gears on the two vibrators mounted on the girder force the vibrator groups to operate in a self-synchronizing way, and the generated resultant force line L is vertical to the screen surface, so that the screen frame generates a linear motion track.
The box type gear forcing vibrator is a double-vibration-shaft vibrator, each vibration shaft is provided with a block eccentric vibrator, and the two vibration shafts are connected through a gear. The screen surface comprises 1-2 layers, and the inclination angle alpha of the screen surface is = 20-30 degrees. One end or two ends of each vibrator group are forced to be connected with the motor transmission device by a box-type gear on each vibrator mounting girder; the vibration reduction supporting devices on the two sides of the screen frame are composed of 2-3 groups. The distance between the two box gears on the two vibrator mounting girders forces the vibrator groups to be equal to one third of the length of the screen frame.
The invention has the beneficial effects that two vibrators are adopted to install the beams, and two groups of box-type gear forced vibrators are respectively installed on the two vibrator installation beams to drive the screen frame to run along a self-synchronizing linear track. The problem of high strength's vibrational force concentrate on the reel, the harm that causes the reel is solved. The screen frame is evenly stressed, and the service life of the screen frame is prolonged. The sieve frame has high integral rigidity, large exciting force, increased number of bearings and enhanced bearing capacity. The resultant force generated by the vibrator is vertical to the screen surface, and the material particles have strong capability of penetrating through the screen and are not blocked. The problems that the rigidity of a screen frame of the existing grading screen with the inclined screen surface is weak, the vibration force is small, the materials are easy to block holes during screening operation, the screening penetration rate is low, and the service life of a bearing of a vibration exciter is short are solved. The screening machine has the characteristics of reasonable structure, good performance, uniform stress, high screening rate and convenience for large-scale development of screening area of the screening machine, and is suitable for screening various materials in the fields of mines, coal mines, road building and life.
