Description
Technical field
The invention belongs to the technical field of campaign-styled sieve, particularly relate to a kind of centrifugal sifting machine for rubber particle.
Background technology
China is big producing country and the consumption big country of rubber in the world, and along with waste old is cumulative, the solid problem of environmental pollution caused is more and more serious, therefore, the regeneration of waste old, to protection of the environment, make rational use of resources significant.Reclaimed rubber technique is by waste old through break process, and the technique such as coarse crushing, magnetic separation obtains rubber powder, and rubber powder, through screening, makes it revert to from elastic stage and has plasticity and viscosity
,again through new rubber that over cure is made again.
Existing rubber screening machine, usually by screen box, screen cloth, vibrating motor forms, and vibrating motor drives screen box vibration, by screen filtration rubber.But because the noise of vibrating motor is very large, long-term work, very easily causes staff's mood irritated, even affects the hearing of staff, cause noise pollution.
Summary of the invention
The invention provides a kind of centrifugal sifting machine for rubber particle, select to solve traditional shaker the problem that machine noise is large.
In order to solve the problem, the invention provides following technical scheme: a kind of centrifugal sifting machine for rubber particle, comprise support spring and screen box, also comprise the first screen drum, second screen drum, first fixed bar, second fixed bar, piston cylinder, piston, connecting rod and bent axle, first screen drum, second screen drum and screen box are the cylindrical shell that one end is closed, first screen drum is placed in the second screen drum, second screen drum is placed in screen box, first screen drum is fixed on the end face of the second screen drum by the first fixed bar, second screen drum is fixed on the end face of screen box by the second fixed bar, piston and piston cylinder are slidably connected, one end of connecting rod is connected on piston, the other end is connected on bent axle, one end of support spring is connected on the end face of bent axle, the other end is connected on screen box.
Principle of the present invention is: piston is at piston cylinder rectilinear motion, drive crankshaft rotating, bent axle drives screen box, the second screen drum and the first screen drum to rotate, due to the effect of centrifugal force, rubber particle in first screen drum and the second screen drum screens through the side of the first screen drum and the second screen drum, one end of support spring is connected on screen box, the other end is connected on the end face of bent axle, due to not exclusively unstable when the first screen drum, the second screen drum and screen box rotate, cause support spring to vibrate, thus drive the vibration of rubber particle.
Beneficial effect of the present invention is: drive piston linear motion by hydraulic pressure thus drive crankshaft rotating, the first screen drum, the second screen drum and screen box is finally driven to rotate, compared with the mode driving screen cloth vibration filtering with conventional vibration motor, overall noise is very little, one end of support spring is connected on screen box, the other end is connected on the end face of bent axle, and can also form vibration, filter effect is outstanding.
Further, the side of the first screen drum and the second screen drum and bottom surface are all provided with equally distributed sieve aperture, and the aperture of the sieve aperture of the first screen drum is greater than the aperture of the sieve aperture of the second screen drum, first carry out coarse filtration by the first screen drum, carefully filter at the second screen drum, filter effect is better again.
Further, piston cylinder is hydraulic cylinder, stable movement and noise is little.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of the embodiment of a kind of centrifugal sifting machine for rubber particle of the present invention.
Detailed description of the invention
Reference numeral during accompanying drawing illustrates is hydraulic cylinder 1, piston 2, connecting rod 3, bent axle 4, the first screen drum 5, second screen drum 6, screen box 7, the first fixed bar 8, second fixed bar 9, support spring 10.
As shown in Figure 1, the present embodiment provides a kind of centrifugal sifting machine for rubber particle, comprise support spring 10 and screen box 7, also comprise the first screen drum 5, second screen drum 6, first fixed bar 8, second fixed bar 9, piston cylinder 1, piston 2, connecting rod 3 and bent axle 4, first screen drum 5, second screen drum 6 and screen box 7 are the cylindrical shell that one end is closed, first screen drum 5 is placed in the second screen drum 6, second screen drum 6 is placed in screen box 7, first screen drum 5 is fixed on the end face of the second screen drum 6 by the first fixed bar 8, second screen drum 6 is fixed on the end face of screen box 7 by the second fixed bar 9
Piston 2 and piston cylinder 1 are slidably connected, and one end of connecting rod 3 connects on the piston 2, and the other end is connected on the end face of bent axle 4, and one end of support spring 10 is connected on bent axle 4, and the other end is connected on screen box 7.
Piston 2 is at hydraulic cylinder 1 rectilinear motion, band dynamic crankshaft 4 rotates, bent axle 4 drives screen box 7, second screen drum 6 and the first screen drum 5 to rotate, due to the effect of centrifugal force, the rubber particle of the first screen drum 5 and the second screen drum 6 li screens through the side of the first screen drum 5 and the second screen drum 6, one end of support spring 10 is connected on screen box 7, the other end is connected on the end face of bent axle 4, due to not exclusively steady when the first screen drum 5, second screen drum 6 and screen box 7 rotate, cause support spring 10 to vibrate, thus drive the vibration of rubber particle.
During use, in the first screen drum 5, send into rubber particle, and to injection liquid force feed in hydraulic cylinder 1, piston 2 does linear reciprocating motion in piston cylinder 1, band dynamic crankshaft 4 rotates.Owing to being hydraulic-driven, comparing and common vibrating screener, move more steady, and noise is very little, few on the impact of operating personnel.Bent axle 4 drives screen box 7, second screen drum 6 and the first screen drum 5 to rotate, and side and the bottom surface of the first screen drum 5 and the second screen drum 6 are all provided with equally distributed sieve aperture, and the diameter of the sieve aperture of the first screen drum 5 is greater than the diameter of the sieve aperture of the second screen drum 6.Due to the effect of centrifugal force, rubber particle first screens roughly through the first screen drum 5, and then enter after the second screen drum 6 carries out second time fine screening and fall into screen box 7, screening effect is better.One end of support spring 10 is connected on screen box 7, the other end is connected on the end face of bent axle 4, owing to can play pendulum when the first screen drum 5, second screen drum 6 and screen box 7 rotate, cause and steadily do not rotate, to such an extent as to the power of vertical direction can be had to support spring 10, the power of vertical direction and the elastic force of support spring 10 interact, and cause the first screen drum 5, second screen drum 6 and screen box 7 to vibrate, thus drive the vibration of rubber particle, make screening effect more outstanding.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
