The utility model discloses a stone vibrating screen for asphalt production, which relates to the field of stone screening devices and comprises an operation cylinder, a first screen drum, a second screen drum and a third screen drum are mounted in the operation cylinder, and a plurality of screening holes are formed in the inner bottom walls of the first screen drum, the second screen drum and the third screen drum. The inner bottom walls of the first screen drum, the second screen drum and the third screen drum are arranged to be inclined faces, and a vibration screening mechanism is installed on the inner bottom wall of the operation drum. The rotating disc drives the eccentric convex shaft to rotate, then the first concentric-square-shaped plate and the connecting plate are driven to integrally move up and down, the connecting plate drives the second concentric-square-shaped plate to move up and down, the sliding block is stressed, the first screen drum, the second screen drum and the third screen drum are driven to move up and down together, vibration is generated, and the inner diameters of the screening holes are sequentially decreased from top to bottom. The stone screening device has the advantages that the multiple screening nets can be driven to vibrate, and the screening effect is achieved.

The utility model relates to the technical field of sludge treatment, and discloses a sludge treatment system which comprises a frame, a motor is fixedly connected to the middle upper portion of the front side of the frame, a connecting rod is fixedly connected to the output end of the motor, a driving chain wheel is fixedly connected to the rear end of the connecting rod, and two rotating rods are rotatably connected to the inner side of the frame at equal intervals. A driven chain wheel is fixedly connected to the front end of the rotating rod on the left side, the driving chain wheel is in transmission connection with the driven chain wheel through a chain, screens are arranged on the outer sides of the two rotating rods, a stirring mechanism is installed at the left end of the front side of the frame, and the stirring mechanism is used for stirring sludge and other chemical agents. According to the garbage screening device, the motor drives the driving chain wheel, the chain and the driven chain wheel to rotate through the connecting rod, so that the rotating rod is controlled to drive the screen to rotate, the effect of screening large-size garbage is achieved, and centralized treatment in the later period is facilitated.

The invention discloses a four-micro-ring band-pass filter which comprises a first linear waveguide, a second linear waveguide and a third linear waveguide which are parallel to one another and are sequentially arranged in a first direction, and the first linear waveguide, the second linear waveguide and the third linear waveguide extend in a second direction perpendicular to the first direction; the first micro-ring and the second micro-ring are arranged between the first linear waveguide and the second linear waveguide and are sequentially arranged along a first direction; and the third micro ring and the fourth micro ring are arranged between the second linear waveguide and the third linear waveguide and are sequentially arranged along the first direction. By cascading the two double-ring filters with different radiuses and utilizing the vernier effect, the ultra-large FSR of the C wave band is realized while the low loss is ensured, the structure is compact, the process is mature, and the thin-film lithium niobate optical chip is suitable for preparation and application of a large-scale thin-film lithium niobate optical chip.

The utility model discloses a multi-stage vibration screening device for activated clay, which comprises a screening box, a plurality of vibrating motors, a plurality of vibrating screens and a plurality of vibrating screens, the base is used for placing the screen box on the ground, and a plurality of springs are arranged between the screen box and the base; wherein a plurality of sieve plates which are vertically distributed at equal intervals are arranged in a cavity of the sieve box, a plurality of strip-shaped holes which are distributed at equal intervals are formed in the sieve plates in a penetrating mode, the strip-shaped holes are transverse to the moving tracks of activated clay particles on the sieve plates, and the width of the strip-shaped holes in the sieve plate located on the upper portion is larger than that of the strip-shaped holes in the sieve plate located on the lower portion. According to the activated clay particle screening device, the effect of screening activated clay particles with different particle size ranges can be achieved, so that the activated clay particles with different particle size ranges can be conveniently subjected to different crushing treatments subsequently, and the risk of reworking treatment is reduced while the quality of finished activated clay particles is guaranteed.
