[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0026] See also Figure 1-3A multi-stage vibration device for a carburizer comprises a screening box 1, a feed port 11 is arranged on the top of the screening box 1, the feed port 11 is connected to a feed pipe 12, a feed hopper 13 is arranged on the feed pipe 12, a bulk material dispenser 2 is arranged below the feed port 11, and a multi-stage screening structure 3 is arranged below the bulk material dispenser 2 in sequence, each stage of the screening structure 3 comprises a screen plate 31, a force sensor 32, a tension spring 33, a mounting plate 34, and a vibration guide rod 35, the screen holes of the screen plates 31 of each stage of the screening structure 3 installed from top to bottom gradually decrease, and the vibration The guide rod 35 is horizontally arranged in the screening box 1, and the two ends of the vibration guide rod 35 are horizontally inserted into the guide holes correspondingly arranged on the two side walls of the screening box 1. One end of the vibration guide rod 35 is provided with a vibration mechanism 4 for driving the vibration guide rod 35 to move horizontally back and forth in the guide hole. The two sieve plates 31 are symmetrically arranged on both sides of the mounting plate 34. The symmetrically arranged mounting plates 34 have the same sieve holes. The material is screened by diverting the material to the sieve plates 31 on both sides to prevent the material from accumulating and damaging the sieve plates. Each sieve plate 31 One end is hingedly connected to a first hinge seat provided on the side of the mounting plate 34, and the other end extends obliquely downward and extends out of the screening box 1 from a discharge port 14 correspondingly provided on the side wall of the screening box 1. A material receiving trough or a belt conveyor is installed at the corresponding discharge port 14 outside the screening box 1 to collect or transport the carbon enhancers of different mesh sizes to the packaging machine for packaging. A spring fixing seat is provided above each sieve plate 31, and the spring fixing seat is elastically connected to one end of a tension spring 33, and the other end of the tension spring 33 is connected to one end of a force sensor 32, and the other end of the force sensor 32 is hingedly connected to a second hinge seat provided on the side wall of the screening box 1. The suspended end of the sieve plate 31 is pulled on the side wall of the screening box 1 by the tension spring 33 and the force sensor 32. When the weight of the material on the sieve plate 31 changes, the weight signal is fed back to the controller, and the vibration intensity of the vibration mechanism 4 on the corresponding sieve plate 31 is controlled by the controller to achieve the purpose of energy saving and consumption reduction. At the same time, the loss of vibration to the sieve plate 31 can be reduced, and the utilization rate of the sieve plate 31 is high.
[0027] In this embodiment, the bulk motor 21 drives the bulk block 22 to rotate, and the recarburizer is evenly dispersed around, and is evenly unloaded onto the multi-stage screening structure 3 through the guide plate 5 for vibration screening in sequence. The vibration screening efficiency is high, and the screening rate of the recarburizer is increased, and excessive wear of the material on the screen plate 31 is reduced. At the same time, multi-stage screening can be achieved with a large screening range. The material on the screen plate 31 is sensed by the force sensor 32, and the corresponding screen plate is vibrated by the vibration mechanism for screening. This can reduce the energy consumption of the screening process and improve the utilization rate of the screen plate.
[0028] In this embodiment, see Figure 2The vibration mechanism 4 includes a vibration motor 41, a vibration plate 42, and a compression spring 43. A vertical vibration plate 42 is arranged at the outer end of the vibration guide rod 35. The middle part of the inner side of the vibration plate 42 is fixedly connected to the vibration guide rod 35. Two horizontal compression springs 43 are symmetrically arranged at the upper and lower ends of the inner side of the vibration plate 42. One end of each compression spring 43 is elastically connected to a first vibration spring seat arranged on the side wall of the screening box 1, and the other end is elastically connected to a second vibration spring seat arranged on the side of the vibration plate 42. Two vibration motors 41 are arranged at the upper and lower ends of the outer side of the vibration plate 42 to support each other. The vibration force generated by the two vibration motors 41 can drive the vibration guide rod 35 to reciprocate horizontally.
[0029] In this embodiment, see Figure 1 An inclined material guide plate 5 is arranged above each sieve plate 31, and the inclination direction of the material guide plate 5 is opposite to the inclination direction of the sieve plate 31. The upper end of the material guide plate 5 is fixedly connected to the inner wall of the screening box 1, and the other end is suspended above the sieve plate 31. The material is introduced into the upper end of the sieve plate 31 through the material guide plate 5, and can move downward by its own gravity.
[0030] In this embodiment, see Figure 3 A partition bar 51 is arranged on each guide plate 5 to evenly disperse the materials for screening, thereby increasing the utilization rate of the screen plate. A plurality of pneumatic vibrators 6 are arranged at the bottom of each guide plate 5 to speed up the falling time of the materials from the guide plate 5.
[0031] In this embodiment, see Figure 1 The bulk material distributor 2 comprises a bulk material motor 21, a bulk material block 22, a fixing rod 23 and a motor seat 24. The bulk material block 22 is a cone with a pointed end facing upward. The bulk material block 22 is located directly below the feed port 11. The bulk material motor 21 is arranged below the bulk material block 22. The output shaft of the bulk material motor 21 is coaxially fixedly connected with the bottom of the bulk material block 22. A motor seat 24 is arranged at the bottom of the bulk material motor 21. The motor seat 24 is fixedly connected with the inner side wall of the screening box 1 through a plurality of fixing rods 23 around it. The motor seat 24 drives the bulk material block 22 to rotate. The material falls on the conical surface of the bulk material block 22, and the material can be evenly dispersed around it.
[0032] In this embodiment, see Figure 1 A streamlined boss 221 is provided on the conical surface of the bulk block 22, so that the material can be evenly dispersed to a farther place.
[0033] In this embodiment, the pneumatic vibrator 6 is an existing commercially available device. The high-pressure gas discharged from the air compressor is connected to the air inlet of the pneumatic vibrator 6 through the air pipe. When the gas pushes the piston upward, the gas in the air chamber on the piston is squeezed, and the squeezed gas is discharged through the exhaust hole. When the piston moves upward to the end point, the gas automatically switches the ventilation direction through the groove and the airway, so that the gas enters the air chamber on the piston. The high-pressure gas pushes the piston downward to the end point, and the first cycle ends, and the second cycle begins. The continuous reciprocating cycle causes the vibrator to produce translation and shaking, thereby generating a vibration force on the sieve plate 31.
[0034] It can be seen from the above technical scheme that when in use, the carburizer is added from the feed hopper 13, and the carburizer enters the screening box 1 through the feed pipe 12 and the feed port 11, and first falls on the bulk material 2, and the bulk material block 22 is driven to rotate by the bulk material motor 21, and the material falling on the bulk material block 22 is scattered, and the scattered material falls on the guide plate 5, and is separated by the dividing bar 5 and falls evenly on the sieve plate 31, and the screened material is discharged from the discharge port 14, and the screened material passes through the sieve plate 31 and falls on the next-level guide plate 5 and is introduced into the upper end of the next-level sieve plate 31, and is driven to vibrate by two vibration motors 41. The movable plate 42 vibrates, causing the vibration guide rod 35 to reciprocate horizontally. The reciprocating movement of the vibration guide rod 35 drives the mounting plate 34 to swing, and the mounting plate 34 drives the sieve plates 31 on both sides to vibrate reciprocatingly at high frequency, so that the material can be screened quickly. When material falls on the sieve plate 31, the sieve plate 31 is slightly displaced under the action of the gravity of the material, driving the tension spring 33 to generate tension. At the same time, the force sensor 32 senses the tension, and the corresponding sieve plate 31 is driven by the corresponding vibration motor 41 to vibrate and screen the material. When a sieve plate 31 does not sense the material, it stops vibrating.
