Abstract
The invention discloses a discharging and reverting system of a chain grate, and the discharging and reverting system comprises a bin, a main conveyor belt and at least one discharging and reverting branch, wherein the discharging and reverting branch comprises a branch conveyor belt and at least one double-layer discharging valve of the chain grate, and the double-layer discharging valve, the branch conveyor belt and the main conveyor belt are respectively provided with a controller; said controllers respectively control the double-layer discharging valve, the branch conveyor and the main conveyor belt, such that materials can be conveyed from the discharging and reverting branch to the main conveyor belt through the branch conveyor belt, and then conveyed into the bin through the main conveyor belt.
Description
Technical field
The present invention relates to mixing system, especially relate to drying grate and unload grey revert system.
Background technology
It is link important in pelletizing production system that drying grate unloads ash, concrete, by the Double-deck cinder discharge valve door of drying grate, the operation of belt conveyor system, can effectively the dry returning charge of drying grate be transported in the feedstock pre-processing system before pelletizing, thus, improve the utilization rate of raw material, realize recycling and the closed cycle of raw material, reduce and to cause because returning charge is uneven material quality to fluctuate large, the affected problem of quality of green pellets, reach the object reduced costs.
In the prior art, drying grate unloads Double-deck cinder discharge valve in grey revert system and belt focus utilization control signal carries out centralized Control, thus, cause drying grate when returning pretreatment of raw material operation, returning charge amount is unstable, when returning charge is excessive, belt is easy sideslip again, thus cause device damage, meanwhile, raw material and pelletizing quality also can be affected.
Summary of the invention
Technical problem to be solved by this invention be in prior art because Double-deck cinder discharge valve and belt utilize a control signal to carry out centralized Control, cause that returning charge is unstable, belt deviation, thus cause device damage.
For overcoming the problems referred to above, the invention provides drying grate and unload grey revert system, comprise feed bin, main belt and at least one unload grey returning charge branch road, described at least one Double-deck cinder discharge valve door unloading grey returning charge branch road and comprise conveyer belt and drying grate along separate routes, described Double-deck cinder discharge valve door, along separate routes conveyer belt and main belt are respectively arranged with a controller;
Wherein, respectively Double-deck cinder discharge valve door, along separate routes conveyer belt and main belt are controlled by each controller, make material can be sent to main belt from unloading grey returning charge branch road through shunt conveyer belt, then be sent to feed bin by main belt.
Further, scope running time of described Double-deck cinder discharge valve door is 30 seconds-120 seconds, and dwell time scope is 30 seconds-1560 seconds.
Further, described feed bin is specially profit abrasive material storehouse and/or bypass feed bin.
The invention has the beneficial effects as follows: by the controller that Double-deck cinder discharge valve door, along separate routes conveyer belt and main belt are arranged respectively, can realize to Double-deck cinder discharge valve door, along separate routes conveyer belt and main belt independent, point other control, it is no longer a concentrated control signal, avoid the situation of returning charge instability, belt deviation, improve the service life of equipment, ensure that material is sent to feed bin uniformly and effectively, meanwhile, also ensure that raw material and pelletizing quality.
Accompanying drawing explanation
Fig. 1 is the structural representation that drying grate of the present invention unloads grey revert system.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme of the application is described in detail.
The drying grate of the application unloads grey revert system, comprise feed bin, main belt and at least one unload grey returning charge branch road, described at least one Double-deck cinder discharge valve door unloading grey returning charge branch road and comprise conveyer belt and drying grate along separate routes, described Double-deck cinder discharge valve door, along separate routes conveyer belt and main belt are respectively arranged with a controller.
By the controller that Double-deck cinder discharge valve door, along separate routes conveyer belt and main belt are arranged respectively, can realize to Double-deck cinder discharge valve door, along separate routes conveyer belt and main belt independent, point other control, it is no longer a concentrated control signal, avoid the situation of returning charge instability, belt deviation, improve the service life of equipment, ensure that material is sent to feed bin uniformly and effectively, meanwhile, also ensure that raw material and pelletizing quality.
In this application, as shown in Figure 1, drying grate unloads grey revert system, comprise feed bin 1, main belt 2 and at least one unload grey returning charge branch road.Difference according to the actual requirements, arrange the quantity of unloading grey returning charge branch road also different, the application does not limit.Material can be sent to main belt 2 by unloading grey returning charge branch road, then is sent to feed bin 1 by main belt 2.
Wherein, each at least one Double-deck cinder discharge valve door 3 unloading grey returning charge branch road and comprise conveyer belt 4 and drying grate along separate routes.Concrete, difference according to the actual requirements, the quantity of Double-deck cinder discharge valve door 3 is also different, and such as, unload in grey returning charge branch road and can comprise 13 Double-deck cinder discharge valve doors 3 etc., the application does not limit.
In the application, Double-deck cinder discharge valve door 3, along separate routes conveyer belt 5 and main belt 3 are respectively arranged with a controller (not shown).Such as, grey returning charge branch road is unloaded when system comprises two, and each unloading in grey returning charge branch road comprises 13 Double-deck cinder discharge valve doors 3, then, unload first on the shunt conveyer belt 4 in grey returning charge branch road and be provided with a controller, unload first on each Double-deck cinder discharge valve door 3 in 13 Double-deck cinder discharge valve doors 3 in grey returning charge branch road and be provided with a controller, unload second on the shunt conveyer belt 4 in grey returning charge branch road and be provided with a controller, to unload on each Double-deck cinder discharge valve door in 13 Double-deck cinder discharge valve doors 3 in grey returning charge branch road 3 second and be provided with a controller, in addition, main belt 2 is also provided with a controller.
In this application, each controller can control Double-deck cinder discharge valve door 3, along separate routes conveyer belt 4 and main belt 2 respectively.Thus, make material can be sent to main belt 2 from unloading grey returning charge branch road through shunt conveyer belt 4, then be sent to feed bin 1 by main belt 2.Wherein, feed bin 1 can be profit abrasive material storehouse and/or bypass feed bin.Because Double-deck cinder discharge valve door 3, along separate routes conveyer belt 4 and main belt 2 are controlled by different controllers, can realize independent, point other control, it is no longer a concentrated control signal, avoid the situation of returning charge instability, belt deviation, improve the service life of equipment, ensure that material is sent to feed bin uniformly and effectively, meanwhile, also ensure that raw material and pelletizing quality.
Preferably, scope running time of separate unit Double-deck cinder discharge valve door 3 is 30 seconds-120 seconds, and dwell time scope is 30 seconds-1560 seconds.
It should be noted that, utilize each controller can realize different control procedures, such as, when needing isolated operation along separate routes, utilize the controller on each shunt conveyer belt, the isolated operation of each shunt conveyer belt can be realized, when needing interlocked control along separate routes, utilize the controller on each shunt conveyer belt, each shunt conveyer belt can be realized and run simultaneously.
