Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an anti-blocking vibrating screen comprises a base 1 and a screen box 2, the screen box 2 is arranged at the upper end of the base 1, the screen box 2 is connected with the base 1 through a buffer seat 3, a screening chamber 4 and a screening chamber 5 are arranged inside the screen box 2, a screening wheel 6 is arranged in the middle of the screening chamber 4, the screening wheel 6 is composed of a wheel body 61, a wheel shaft 62, an annular net ring 63 and an annular side plate 64, the wheel shaft 62 is arranged on the wheel body 61, one end of the wheel shaft 62 is inserted into a shaft hole 21 formed in the side wall of the screen box 2, the annular net ring 63 is sleeved on the wheel body 61, the annular side plate 64 is arranged on the two side surfaces of the annular net ring 63, a scraper 7 is arranged on the outer side wall of the screening chamber 5, a scraping hair 71 is arranged at the bottom of the scraper 7, a discharge port 51 is formed in the inner side wall of the screening chamber 5, a movable door 8 is arranged in the discharge port 51 through a rotating shaft, a motor 9 is arranged on the outer side wall of one side of the screen box 2, an output shaft of the motor 9 is inserted into the shaft hole 21 in the side wall of the screen box 2, and is connected with a wheel shaft 62, the outer side wall of the other side of the screen box 2 is provided with a motor 10, and the output shaft of the motor 10 is provided with an eccentric wheel 11.

In the aforesaid, drive screening wheel 6 through motor 9 and rotate, start motor 10 drives eccentric wheel 11 simultaneously and rotates, and the centrifugal force that produces when utilizing the high-speed rotation of eccentric wheel 11 can transmit for motor 10 to act on sieve case 2 and produce the vibration, consequently with the gravel input sieve case 2 in and when falling on screening wheel 6, the gravel is sieved by annular net circle 63 under the effect of vibration.

Because the diameter of the mesh of the annular net ring 63 is less than or equal to 4.75 mm, gravel with different diameters is sieved by passing through the annular net ring 63, so that the sieving operation after raw materials are crushed is realized, and the large-diameter gravel sieved on the sieving wheel 6 is scraped by the scraping plates 71 to enter the sieving chamber 5 through the action of the scraping plates 7 so as to be collected and reprocessed in a centralized manner.

The buffer base 3 comprises an upper base plate 31, a lower base plate 32 and a spring 33, wherein the upper base plate 31 is installed at two ends of the screen box 2, the lower base plate 32 is installed at two ends of the screen base 1, the spring 33 is arranged between the upper base plate 31 and the lower base plate 32, one end of the spring 33 is connected with the upper base plate 31, and the other end of the spring 33 is connected with the lower base plate 32.

In the above, when the screen box 2 is in the vibrating process, the effect of the vibrating force is counteracted by the continuous deformation of the spring 33, so that the screen box 2 can still be kept stable in the vibrating state.

Because the bottom of scraper blade 7 is the cambered surface to with annular net circle 63 phase-match, the bottom of scraper blade 7 extends to on the annular net circle 63 to make the scratch 71 attach on the wire side of annular net circle 63, so when screening wheel 6 rotated, scrape out the gravel that gathers on annular net circle 63 through scratch 71, in order to avoid the wire side of annular net circle 63 to be blockked up by the gravel and influence the screening operation.

Because the middle part of frame 1 is equipped with stock chest 12, and stock chest 12 is just to the discharge gate of sieve case 2 bottom, so the gravel that the sieve filtered out is discharged through the discharge gate of frame 1 bottom to fall into the collection in stock chest 12.

This anti-blocking vibrating screen, with the grit input sieve incasement 2 and fall on screening wheel 6 in screening chamber 4, starter motor 9 and motor 10 this moment, drive screening wheel 6 through motor 9 and rotate and under scraper blade 7's effect, make the large-grained gravel that the screening was filtered out on screening wheel 6 scrape the brush play and get into screening chamber 5 by scraping hair 71, drive eccentric wheel 11 through motor 10 simultaneously and rotate, and the centrifugal force that produces when eccentric wheel 11 is high-speed rotatory can transmit for motor 10, thereby act on sieve case 2 and produce the vibration, realize that the screening of screening wheel 6 is strained and is scraped the brush and go on in step, so can effectively avoid screening wheel 6 the condition that blocks up to appear, accomplish the operation of straining to the gravel.

In summary, the following steps: this prevent stifled shale shaker, through the sieve case 2 of vibration and carry out the screening wheel 6 of screening operation, the screening that realizes screening wheel 6 is strained and is scraped the brush and go on in step, therefore can effectively avoid screening wheel 6 by the condition of the grit jam of gathering, improves the screening operation to the grit, solves prior art problem.
