Description
Technical field
Lime production technical field is the utility model is related to, is specially that a kind of lime shaft preheater blanking automatically controls dress
Put.
Background technology
At present, in rotary kiln lime production technology, the control of preheater blanking is execute-in-place work according to output demand,
By kiln temperature situation, preheater blanking and corresponding adjustment rotary kiln rotating speed, shortcoming are controlled manually：Labor intensity is big, work
Efficiency is low, for this reason, we have proposed a kind of lime shaft preheater blanking automatic controller.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of lime shaft preheater blanking automatic controller
The problem of labor intensity proposed in background technology is big, and work efficiency is low.
To achieve the above object, the utility model provides following technical solution：A kind of lime shaft preheater blanking is automatic
Control device, including PLC system, it is spacing that the electrical input of the PLC system is connected with kiln temperature monitoring system, blanking push rod
Device, the PLC system are connected with HMI touch-screens by PROFINET buses, and electrically output is connected with preheating to the PLC system
Device blanking device.
Preferably, the PLC system is S7-1200PLC systems.
Preferably, the HMI touch-screens are LEDHMI touch-screens.
Compared with prior art, the beneficial effects of the utility model are：Controlled automatically by the blanking of this lime shaft preheater
The setting of device processed, can replace operative employee to control, and reduce operative employee's labor intensity, and work efficiency is high.
Brief description of the drawings
Fig. 1 is utility model works schematic diagram；
Fig. 2 is the utility model control principle drawing.
In figure：It is 1 PLC system, 2 kiln temperatures monitoring system, 3 blanking push rod limiting devices, 4 HMI touch-screens, 5 pre-
Hot device blanking device.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
- 2 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of lime shaft preheater blanking automatically controls
Device, including PLC system 1, it is spacing that the electrical input of the PLC system 1 is connected with kiln temperature monitoring system 2, blanking push rod
Device 3, the PLC system 1 are connected with HMI touch-screens 4 by PROFINET buses, and electrically output is connected with the PLC system 1
Preheater blanking device 5.
Wherein, the PLC system 1 is S7-1200PLC systems, and control effect is good, and the HMI touch-screens 4 touch for LEDHMI
Touch screen, good energy-conserving effect.
Operation principle：This lime shaft preheater blanking automatic controller, it includes control device and Site Detection is set
Standby, signal and parameters of technique process according to Site Detection cell feeds back control controller switching equipment after 1 computing relatively of PLC system,
Realize automatically controlling for shaft preheater blanking.HMI touch-screens 4 may be alternatively mounted at control room according to technological requirement or scene is controlled
On chamber door processed, it is connected by PROFINET buses with the programmable PLC system 1 in control cabinet, display charging ram working status (position
Put), real-time discharge quantity, accumulative discharge quantity, preheater blanking putter action interval time, the control cabinet of programmable PLC system 1
In be also equipped with air switch, intermediate relay and its input, output interface, the input interface of PLC system 1 connects blanking respectively
Output demand signal, the kiln temperature that limit signal, the DCS of the transmission of push rod limiting device 3 are sent monitor time that system 2 is sent
With kiln end temperature signal in rotary kiln kiln, rotary kiln is interior and kiln end temperature signal is used for determining whether combustion position has in rotary kiln
It is close to for the working condition requirement under the setting yield and according to temperature change dynamic adjustment yield and reaches setting output demand,
PLC system 1, according to production requirement, sets the daily output and preheater using the S7-1200 of Siemens Company on HMI touch-screens 4
Push rod single discharge quantity, live rotary kiln is interior and kiln end temperature enters PLC systems by DCS system 4~20mA of outputting standard signals
System 1, in PLC system 1 computing draw the blanking putter action interval time of preheater blanking device 5, pass through output driving control
Blanking push rod electromagnetism valve events processed, complete automatic blanking.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from the principle of the utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
