DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, a multi-axis circular vibrating screen has a screening chamber 20, which is an inclined hollow rectangular shell.

An eccentric block 26 is fixedly connected, and the eccentric block 26 is a fan-shaped block. A spring assembly 27 is fixedly connected to the bottom of the rectangular block of the bracket 23. A plurality of brackets 23 are evenly arranged at the bottom of the screening chamber 20. Each bracket 23 is provided with the same rectangular block, drive motor 24, rotating shaft 25, eccentric block 26 and spring assembly 27. The drive motor 24 is electrically connected to the corresponding power supply. The spring assembly 27 is a rubber air spring of model 168132H-2. This is an existing technology, so it will not be described here.

[0031] like Figure 2 、 Figure 3 and Figure 4As shown, the efficiency-enhancing structure is arranged in the cavity of the screening chamber 20. The efficiency-enhancing structure can improve the efficiency of pearlite sand screening in the cavity of the screening chamber 20. The efficiency-enhancing structure includes: a sieve plate 30, a sieve hole 31, a limit block 32 and a limit slot 33. The sieve plate 30 is movably arranged in the middle section of the cavity of the screening chamber 20, the sieve hole 31 is opened at the top of the sieve plate 30, the limit block 32 is fixedly connected to the side wall of the sieve plate 30, and the limit slot 33 is opened on the side wall of the cavity of the screening chamber 20. The sieve plate 30 can move up and down in the cavity of the screening chamber 20.

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the sieve plate 30 is a rectangular plate, which can divide the upper and lower parts of the screening chamber 20 into separate spaces. The sieve holes 31 are circular holes, and multiple sieve holes 31 are evenly opened on the top of the sieve plate 30. A plurality of identical limit blocks 32 are evenly arranged on the walls on both sides of the sieve plate 30. The limit blocks 32 are right-angled trapezoidal blocks with the inclined surfaces facing upwards. The number of limit grooves 33 is consistent with that of the limit blocks 32. Each limit block 32 can slide up and down in the corresponding limit groove 33, and the limit groove 33 can adapt to the sliding of the limit block 32. The synergistic structure also includes a blocking block 34, a push rod 35, a push rod 36 and a discharge pipe 37. The blocking block 34 is fixedly connected to the top of the sieve plate 30 and is fixed by the push rod 35 The cam 36 is connected to the bottom of the sieve plate 30, the push rod 36 is fixedly connected to the arc surface of the rotating shaft 25, the discharge pipe 37 is fixedly connected to the front wall of the screening chamber 20, the blocking block 34 is a right triangle block, and a plurality of identical blocking blocks 34 are evenly arranged on the top of the sieve plate 30. The pushed rod 35 is a semi-arc rod, and the pushed rod 35 is respectively arranged on the bottom wall of the sieve plate 30 above the position of each rotating shaft 25. The push rod 36 is an arc rod, and the push rod 36 is respectively arranged on the arc surface of each rotating shaft 25. The arc surface of the push rod 36 can contact the arc surface of the bottom of the pushed rod 35, and the discharge pipe 37 is a U-shaped tube with an opening facing upward, and the wall surface of the discharge pipe 37 is also fixedly connected to the front wall of the sieve plate 30;

[0033] During specific use, the pearlite sand to be screened is added into the screening chamber 20 cavity from the feed port 21, and the power is turned on. After the pearlite sand is added into the screening chamber 20 cavity from the feed port 21, it will directly fall into the top of the screen plate 30. At this time, the driving motor 24 will drive the rotating shaft 25 to rotate when the power is turned on. The rotating shaft 25 can drive the eccentric block 26 to rotate at the same time when rotating. The eccentric block 26 can bring centrifugal force to the screening chamber 20 during rotation, so that the screening chamber 20 can shake in a circular trajectory. The screening chamber 20 can drive all the structures in the cavity to shake at the same time when shaking. The pearlite sand is on the top of the screen plate 30 and can pass through the sieve hole 31 to screen the pearlite sand as the screen plate 30 shakes. The pearlite sand with a size smaller than the sieve hole 31 will directly leak from the sieve hole 31 to the bottom of the screening chamber 20 cavity, and then as the screen The bottom of the chamber 20 moves to the discharge port 22 and is discharged from the screening chamber 20, while the pearlite sand that is not screened out by the sieve holes 31 can move along the top of the sieve plate 30 to the top opening of the discharge pipe 37 and then be discharged along the top of the discharge pipe 37. When the rotating shaft 25 is driven to rotate by the driving motor 24, the rotating shaft 25 can drive the abutting rod 36 to rotate at the same time. The abutting rod 36 can contact the arc surface of the bottom of the abutted rod 35 when it rotates upward, and then the abutted rod 35 can be pushed upward. The abutted rod 35 can drive the sieve plate 30 to move upward at the same time when it is pushed upward, and the sieve plate 30 can drive the limit block 32 to move in the limit groove 33 at the same time. At this time, the pearlite sand on the top of the sieve plate 30 can be vibrated by the movable sieve plate 30 in cooperation with the stop block 34, and the pearlite sand stuck in the sieve holes 31 will also be vibrated off.

[0034] In summary, by setting up a synergistic structure, the activity of pearlite sand during screening in the screening chamber 20 can be improved, because the synergistic structure can drive the eccentric block 26 to rotate through the rotating shaft 25 to perform circular trajectory shaking screening, and can also drive the push rod 36 to push the screen plate 30 upward so that the pearlite sand on the top of the screen plate 30 is vibrated to simulate the throwing of the pearlite sand, thereby effectively improving the screening efficiency of the device. Therefore, compared with the existing technology, the screening efficiency of this solution is higher.

[0035] like Figure 1 、 Figure 2 and Figure 5As shown, an adjustment structure is provided at the bottom of the bracket 23, and the adjustment structure includes a front frame 40, a front axle 41, a rear frame 42 and a rear axle 43. The front frame 40 is fixedly connected to the bottom of the symmetrical spring assembly 27 at the front, the front axle 41 is fixedly connected to the side wall of the front frame 40, and the front axle 41 is cylindrical. The rear frame 42 is fixedly connected to the bottom of the symmetrical spring assembly 27 at the rear position, and the rear axle 43 is fixedly connected to the bottom of the rear frame 42. The rear frame 42 is composed of a rectangular plate on the top and a symmetrical L-shaped rod at the bottom of the rectangular plate. The rear axle 43 is fixedly connected to the symmetrical L-shaped rod of the rear frame 42. The adjustment structure further includes a first transition piece 44, a second transition piece 45, a bottom plate 46 and an electric cylinder 47. The first transition piece 44 is rotatably connected to the wall of the rear axle 43, the second transition piece 45 is rotatably connected to the wall of the front axle 41, the bottom plate 46 is fixedly connected to the bottom of the second transition piece 45, and the electric cylinder 47 is rotatably connected to the top of the bottom plate 46. The front axle 41 can pass through the side wall of the second transition piece 45. The bottom plate 46 is a T-shaped plate. The bottom of the electric cylinder 47 can rotate with the top of the bottom plate 46. The top of the electric cylinder 47 is also fixedly connected to the bottom of the first transition piece 44.

[0036] During specific use, the electric cylinder 47 can be extended in length by turning on the power supply. The electric cylinder 47 is electrically connected to the corresponding power supply. When the device is working, the bottom plate 46 will be placed flat on the ground. When the electric cylinder 47 is extended in length, the electric cylinder 47 can push the first transition piece 44, and then the first transition piece 44 will rotate on the wall surface of the rear shaft 43. At this time, the rear frame 42 will be moved upward by the moved rear shaft 43, so that the inclination angle of the entire screening chamber 20 is steeper. When the length of the electric cylinder 47 is reduced, the screening chamber 20 will also be inclined more horizontally.

[0037] In summary, by setting up an adjustment structure, the inclination angle of the screening chamber 20 can be adjusted by adjusting the length of the electric cylinder 47, and when the screening chamber 20 is tilted, it can simultaneously drive the screen plate 30 for screening the pearlite sand to tilt at the same time. The smaller the inclination angle of the screening chamber 20, the slower the speed of the pearlite sand flowing on the top of the screen plate 30. Therefore, the inclination angle of the screening chamber 20 can be freely adjusted by the adjustment structure, thereby flexibly controlling the overall screening speed of the device.

[0038] Working principle: add the pearlite sand to be screened into the screening chamber 20 cavity from the feed port 21, and turn on the power. After the pearlite sand is added into the screening chamber 20 cavity from the feed port 21, it will directly fall into the top of the screen plate 30. At this time, the drive motor 24 will drive the rotating shaft 25 to rotate when the power is turned on. The rotating shaft 25 can drive the eccentric block 26 to rotate at the same time when rotating. The eccentric block 26 can bring centrifugal force to the screening chamber 20 when rotating, so that the screening chamber 20 shakes in a circular trajectory. The screening chamber 20 can drive all the structures in the cavity to shake at the same time when shaking. The pearlite sand is on the top of the screen plate 30 and can pass through the sieve hole 31 to screen the pearlite sand as the screen plate 30 shakes. The pearlite sand with a size smaller than the sieve hole 31 will directly leak from the sieve hole 31 to the bottom of the screening chamber 20 cavity, and then as the screening The bottom of the chamber 20 moves to the discharge port 22 and is discharged from the screening chamber 20, while the pearlite sand that is not screened out by the sieve holes 31 can move along the top of the sieve plate 30 to the top opening of the discharge pipe 37 and then be discharged along the top of the discharge pipe 37. When the rotating shaft 25 is driven to rotate by the driving motor 24, the rotating shaft 25 can drive the abutting rod 36 to rotate at the same time. The abutting rod 36 can contact the bottom arc surface of the abutted rod 35 when it rotates upward and then push the abutted rod 35 upward. The abutted rod 35 can drive the sieve plate 30 to move upward at the same time when it is pushed upward. The sieve plate 30 can drive the limit block 32 to move simultaneously in the limit groove 33. At this time, the pearlite sand on the top of the sieve plate 30 can be vibrated by the movable sieve plate 30 in cooperation with the blocking block 34, and the pearlite sand stuck in the sieve holes 31 will also be vibrated off.
