Embodiment, belong to the scope of protection of the invention.
It is an object of the invention to provide a kind of screening plant, screening component has multiple, is also correspondingly arranged on multiple frequency modulators
With multiple sensors, vibrating motor power output is controlled to make itself and aggregate so as to adjust the vibration frequency of screen cloth by frequency modulator
Intrinsic frequency is same or like, so as to reach resonance or close to resonance, screening plant separate operatons at different levels, not interfere with each other, mutually
Independently working, screening efficiency efficiency high, screening process are more accurate, have very high practical value.
In order to facilitate the understanding of the purposes, features and advantages of the present invention, it is below in conjunction with the accompanying drawings and specific real
Applying example, the present invention is further detailed explanation.
The present invention provides a kind of screening plant, as shown in Figure 1, Figure 2 and Figure 3, including a feed opening 1, cover 2, shell 3,
Vibrating motor 4, vibrating shaft 5 and screening component 7, feed opening 1 are opened in the top of cover 2, and cover 2 is placed in the top of shell 3, screening portion
Part 7 is disposed with multiple from top to bottom, and each screening component 7 is correspondingly arranged on a vibrating shaft 5 and vibrating motor 4, respectively shakes
Dynamic motor 4 is both secured on shell 3, and each screening component 7 may be contained within the corresponding top of vibrating shaft 5 and can be connect with vibrating shaft 5
Touch, the output shaft of each vibrating motor 4 connects with corresponding vibrating shaft 5.In the screening process of actual reproduction aggregate, regeneration aggregate
Enter from feed opening, successively by the screening component set gradually from top to bottom, screening component separate operatons at different levels, do not do mutually
Disturb, the screening efficiency efficiency high of regeneration aggregate, screening process are more accurate, have very high practical value.
In order to realize steady vibrations of the screening component in screening process, in the specific embodiment of the present invention, vibrating shaft 5
Including the first axle be arrangeding in parallel and the second axle, being set for parallel lines twin shaft, first axle is connected with the second axle by universal driving shaft 6,
The both ends of first axle or the second axle are corresponding to be connected with vibrating motor 4, and vibrating motor 4 is connected with when first axle both ends are corresponding
When, because first axle is connected with the second axle by universal driving shaft 6, the first shaft vibration drives universal driving shaft 6 to vibrate, and universal driving shaft 6 drives the
Two shaft vibrations, when the second axle both ends, which correspond to, is connected with vibrating motor 4, because first axle and the second axle pass through the phase of universal driving shaft 6
Even, the second shaft vibration drives universal driving shaft 6 to vibrate, and universal driving shaft 6 drives the first shaft vibration, and both modes, which can be realized, synchronously shakes
Dynamic, the vibration of overall screening component is more uniform.
In the specific embodiment of the present invention, each screening component 7 includes screen cloth 7-1, movable bracket 7-2 and elastomeric element
7-3, movable bracket 7-2 are fixedly arranged on vibrating shaft 5, and movable bracket 7-2 both ends are connected by elastomeric element 7-3 with shell 3,
Screen cloth 7-1 is located in shell 3 and is arranged on movable bracket 7-2.When vibrating shaft 5 vibrates, because movable bracket 7-2 consolidates
On vibrating shaft 5, therefore movable bracket 7-2 receives upward thrust, and then movable bracket 7-2 is popped up, now, screen cloth
7-1 is popped up, and elastomeric element 7-3 is pulled generation elastic deformation, and regeneration aggregate receives upward thrust and moved upwards, this
When, elastomeric element 7-3 resiliences, drive movable bracket 7-2 and screen cloth 7-1 to move downward, and so on move, can be to Regenerated Bone
Material is sieved, and screening efficiency efficiency high, screening process are more accurate.
Preferably, in the specific embodiment of the present invention, elastomeric element 7-3 is spring, and simple and easy to get, cost is relatively low.From
The aperture for each screen cloth 7-1 that top to bottm is set gradually tapers into, therefore, regeneration aggregate when the superiors' screen cloth is sieved,
Primary screener can be carried out, the regeneration aggregate of greater particle size is screened out to come, then, the regeneration aggregate after being screened is in the second layer
Screen cloth is screened, and can be screened the regeneration aggregate of the greater particle size after first time screens again, under sieving successively
Go, progressive, screening process is each independent, and screening efficiency is higher.
In order to preferably be separated the regeneration aggregate screened, each screening component 7 is both with respect to horizontal plane
Set, angle of inclination is 10 °, and the opening position that shell 3 corresponds to the least significant end of each screening component 7 is provided with a discharging opening
14, therefore, the regeneration aggregate after screening can be discharged from each self-corresponding discharge outlet.
In order to which the regeneration aggregate after screening is transported, a belt conveyor is provided with each discharging opening 14
13, one end of belt conveyor 13 is fixed on shell 3, and the regeneration aggregate after screening is arranged from each self-corresponding discharging opening
After going out, fall on the feed belt of each self-corresponding belt conveyor, and as feed belt transports carry out post-processing.
In order to improve the accuracy of screening process, each screening component 7 is correspondingly arranged on a frequency sensor 8, a frequency modulation
The control cabinet 10 of device 9 and one, each frequency sensor 8 are installed on corresponding screen cloth 7-1 tops, and control cabinet 10 is fixedly arranged on shell 3, respectively
Frequency modulator 9 may be contained within control cabinet 10, and each frequency sensor 8 electrically connects with corresponding frequency modulator 9, and each frequency modulator 9 passes through
Lead-out terminal electrically connects with corresponding vibrating motor 4.Therefore, in screening process, frequency sensor can detect vibration in real time
The vibration frequency of part, frequency modulator controls vibrating motor power output according to the output signal of frequency sensor, so as to adjust
The vibration frequency of screen cloth, make it same or like with aggregate intrinsic frequency, so as to reach resonance or be imitated close to resonance, screening efficiency
Rate is high, screening process is more accurate.
For the ease of the observation to screening process, each screening component 7 is correspondingly arranged on a monitoring device 15 and a control
Device, each monitoring device 15 are electrically connected with the controller, and each monitoring device 15 is fixedly arranged on shell 3, and each monitoring device 15 is set respectively
In the high-end tops of corresponding screen cloth 7-1, each monitoring device 15 includes camera, lighting device and rain brush, camera and
Lighting device is arranged in glass outer, and rain brush is arranged at outside glass outer and contacted with glass outer, each camera, each
Lighting device and each rain brush are electrically connected with the controller.The setting of camera, can more clearly reflect screening process, one
There is screening inaccuracy in denier, can make adjustment in time, when insufficient light, lighting device can supplement light, can be more
Clearly monitor screening process.The setting of glass outer, can illumination apparatus and camera protected well, prevent bone
Material beats equipment and collided damage, and the setting of rain brush can be cleared up the laying dust of glass outer in time.
In the specific embodiment of the present invention, chassis 11 and crawler type advance system 12 are additionally provided with, chassis 11 is fixedly arranged on
The positive bottom of shell 3, crawler type advance system 12 are located at the bottom on chassis 11, and compact, device is simple, realize screening system
