Specific embodiment
Technology contents, construction feature, the objects and the effects for detailed description technical solution, below in conjunction with specific reality
It applies example and attached drawing is cooperated to be explained in detail.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, the present embodiment provides a kind of lime stone multistage sizing equipments, including the first screen-dividing machine
Structure 10, the second sub-sieve mechanism 20, feed hopper 30, discharge nozzle 40 and rack 50, the first sub-sieve mechanism and the second screening mechanism are by upper
It is mounted on the rack under.First sub-sieve mechanism includes sub-sieve cavity 11, blowing unit 12 and delivery pipe 13, and blowing unit is sieve
Thatch air blower, lateral flow type blower or multistage centrifugal blower.Second sub-sieve mechanism structure setting identical as the first sub-sieve mechanism.It will
Feed hopper is mounted on the top surface of the sub-sieve cavity of the first sub-sieve mechanism, or installation, on blast pipe 14, blast pipe is to be used for
Connect the pipeline of blowing unit and sub-sieve cavity.Passing through guiding tube 15 for the sub-sieve cavity and the second sub-sieve of the first sub-sieve mechanism
The sub-sieve cavity of mechanism connects, and the sub-sieve cavity of the first sub-sieve mechanism can also be connect with the blast pipe of the second sub-sieve mechanism.
Reach to be delivered in the second sub-sieve mechanism by the lime stone of the first sub-sieve mechanism sub-sieve and carries out sub-sieve.And thin after point solarization
Grain lime stone, which is then guided by delivery pipe, to be stored, the delivery pipe of delivery pipe and the second sub-sieve mechanism for the first sub-sieve mechanism it
Between conducting is attached by connecting tube 16, achieve the purpose that through a delivery pipe output.
Therefore when carrying out sub-sieve, first the lime stone of sub-sieve will be needed to be delivered in sub-sieve cavity via feed hopper, and open
Blowing unit is opened by blast pipe towards drying in sub-sieve cavity, so that the lime stone of sub-sieve cavity is driven by air-flow towards conveying
The direction of pipe is flowed, and has Screening Network in sub-sieve cavity, therefore fine grain lime stone is exported by sub-sieve by delivery pipe, and
Coarse grained lime stone can then be fallen in guiding tube due to heavier-weight, and be delivered to the second sub-sieve mechanism again by guiding tube
Secondary carry out sub-sieve.Then, coarse grained lime stone is exported via discharge nozzle, and fine grain lime stone and the first sub-sieve mechanism
Delivery pipe be conducted conveying, achieved the purpose that abundant sub-sieve lime stone.
Sub-sieve cavity includes seal box 111 and sub-sieve unit 112 in the present embodiment, and sub-sieve unit includes sliding frame 1121
With Screening Network 1122, sliding frame includes screening area 1123 and spare sieve subregion 1124, sub-sieve cavity further include vibration motor
1125, the vibration motor is arranged on the hull outside face of sub-sieve cavity.Feed inlet, fine grained lime are offered on seal box
The outlet of fine grained lime stone is open by stone outlet, granular limestone outlet and air inlet by sub-sieve unit with other three
It separates, i.e., sub-sieve unit is arranged in the outlet of fine grained lime stone.In order to avoid Screening Network blocking causes entire sub-sieve to set
Standby shutdown maintenance, therefore Liang Ge sub-sieve area is opened up on sliding frame, area and spare sieve subregion are respectively sieved, while sieving
Screening Network is installed in area, spare Screening Network 1126 is installed on spare sieve subregion, Screening Network and spare Screening Network are all for screening
The diameter of net, mesh can be suitable for fine sub-sieve between 0.074mm-5mm；Or the diameter of mesh is in 5mm-10mm
Between, suitable for the sieving being fed greatly.Sliding frame is installed through the two sides of seal box, thus can with and change screening area and spare
Screening area is in carrying out sub-sieve in seal case, and one circle rubber of installation is close on the position contacted between sliding frame and seal case
Packing or rubber seal, it is ensured that leakproofness when sub-sieve in seal box.Sub-sieve is carried out using the Screening Network in screening area, when this
When Screening Network blocks, by pushing or pull on sliding frame, spare sieve subregion is moved in seal box, spare sieve is passed through
Subnetting carries out sub-sieve.Screening Network can be placed in outside simultaneously, therefore in the case where not influencing sub-sieve, can also to Screening Network into
Row cleaning is spare, improves sub-sieve component efficiency.
Vibration motor 1125 is installed on sub-sieve cavity in the present embodiment, and bullet is installed between sub-sieve cavity and rack
Spring 1127, by way of hanging in the present embodiment, by eight apex angles hanging of rectangular sub-sieve cavity in rack, because
, when opening vibration motor, vibration motor can shake entire sub-sieve cavity for this, can will then be delivered in screening cavity
Lime stone shaken, and the air of air blower is combined to flow, carries out lime stone and air to be sufficiently mixed sub-sieve.It shakes simultaneously
Dynamic motor can also shake sub-sieve, effectively avoid or reduce the probability of Screening Network blocking.And delivery pipe, guiding tube and
The part that feed hopper is connect with sub-sieve cavity is telescopic bellows, therefore when being shaken, not will drive each pipeline and tremble
It is dynamic, improve the practicability of sub-sieve.
In order to avoid the blocking of pipeline Screening Network is in time knows that accident occurs in the present embodiment, pipe is provided in delivery pipe
Road air monitoring device 131, the model of air velocity duct monitor can be 923 hot-wire array measuring instrument of Fluke.At first point
One air velocity duct monitor is respectively installed in the delivery pipe of screening mechanism and the second sub-sieve mechanism, passes through the screen of air velocity duct monitor
The wind speed in pipeline can be monitored in real time in curtain, if the numerical value of the air velocity of detection reduces suddenly in the case where normal work
It is more, then can be determined that Screening Network blocking or conveyance conduit rupture, can timely shutdown maintenance, avoid the generation of accident, reach
The purpose of safety detection is arrived.
In the present embodiment in order to ensure lime stone in sub-sieve cavity abundant sub-sieve, on guiding tube install valve 151, out
Discharge valve 41 is mounted in expects pipe, valve and discharge valve can be butterfly valve, ball valve or check-valves etc..By closing valve
Door makes sub-sieve cavity form a closed cavity, and time opening valve conveys coarse grained lime stone by guiding tube
Sub-sieve again is carried out in the second sub-sieve mechanism, without stopping the charging of feed hopper, to improve the efficiency of lime stone sub-sieve.
Valve and discharge valve can be set simultaneously not open simultaneously, therefore can directly be fallen to avoid the lime stone of feed hopper in charging
The possibility for entering discharge nozzle improves the practicability of lime stone multistage sizing equipment.And at sub-sieve fine grained lime stone then pass through it is defeated
It send pipe to be delivered in cloth bag 60, because cloth bag has the function of breathing freely, fine grain lime stone can be collected, and be discharged
Air achievees the purpose that good collection.
It should be noted that being not intended to limit although the various embodiments described above have been described herein
Scope of patent protection of the invention.Therefore, it based on innovative idea of the invention, change that embodiment described herein is carried out and is repaired
Change, or using equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, it directly or indirectly will be with
Upper technical solution is used in other related technical areas, is included within the scope of protection of the patent of the present invention.
