Description

Technical Field

[0001] The invention relates to the technical field of cement processing equipment, in particular to an intelligent kiln door. Background Art

[0002] Cement clinker is made of limestone, clay and iron raw materials as main raw materials, which are prepared into raw materials in appropriate proportions, burned until partially or completely melted, and cooled to obtain semi-finished products. The common processing method in the prior art is to heat the raw materials in a rotary kiln, and the carbonate inside it is further rapidly decomposed and a series of solid-phase reactions occur to generate minerals in cement clinker. As the material temperature rises, the minerals will turn into liquid phase, dissolve in the liquid phase and react, eventually generating a large amount of clinker.

[0003] At present, in the cement clinker burning system, the kiln head hood is the key position connecting the rotary kiln and the cooler. The reliability of the kiln door sealing is crucial to the stable production of the entire burning system. The existing kiln doors are mainly of two types: track-type sliding doors and embedded double-leaf doors. Gaps are easily generated between the track-type sliding doors and the end plates of the kiln head hood. During production, hot air and materials continuously flush the kiln door through the gap, causing it to deform, thereby affecting the sealing effect; the embedded double-leaf door has good sealing performance, but it is cumbersome to open and close during inspection and maintenance and there are certain safety hazards. Therefore, in response to the above problems, the present application will provide a smart kiln door to solve the problems existing in the above-mentioned prior art. Summary of the invention

[0037] The comprehensive monitoring system includes a comprehensive monitoring device 3, a temperature sensor, a pressure sensor and a gas sensor installed on the left kiln door 4. An observation window 8 is embedded in the right kiln door 7. A kiln door sealing device 17 is provided in the annular gap formed by the surface of the kiln head burner bushing 13 and the left kiln door 4 and the right kiln door 7. The kiln door sealing device 17 includes a high temperature resistant sealing filler, and the kiln door sealing device 17 is installed on the left kiln door 4.

[0038] The number of automatic locking devices is not less than two and they are evenly distributed between the kiln door installation surface 9 and the left kiln door 4 and between the right kiln door 7 and the kiln door installation surface 9;

[0039] The automatic locking device 6 is composed of a first automatic locking device body and a first locking buckle 14. The first locking buckle 14 is installed on the surface corresponding to the kiln door installation surface 9. The first automatic locking device body includes a secondary linear actuator and an inclined limit block connected to the output end of the secondary linear actuator, and the inclined limit block can be reciprocatedly locked or given way with the first locking buckle 14 in the transmission of the secondary linear actuator.

[0040] A driving device is provided on both sides of the kiln door installation surface 9, and the driving device can be drivingly connected with the movable end of the hinge mechanism 2 corresponding to the left kiln door 4 or the movable end of the hinge mechanism 2 corresponding to the right kiln door 7, so that the left kiln door 4 or the right kiln door 7 can be automatically turned over synchronously to close the internal space of the kiln door installation surface 9, and the driving device is composed of any one or two of an actuator, a pneumatic transmission system, and a hydraulic transmission system;

[0041] The driving device is composed of a linear actuator 1, and the linear actuator 1 is installed on the surface corresponding to the kiln door installation surface 9, and the output end of the linear actuator 1 can be transmission-connected with the movable end of the hinge mechanism 2 corresponding to the left kiln door 4 or the movable end of the hinge mechanism 2 corresponding to the right kiln door 7;

[0042] A safety detection probe 5 is installed on the kiln door mounting surface 9. The safety detection probe 5 specifically adopts a high-temperature resistant camera, and the safety detection probe 5 is electrically connected to the control device 10 through a wire and transmits real-time monitoring data to the control device 10. The control device 10 includes a display module, a processor module, an image recognition module and an alarm module. The safety detection probe 5 transmits the monitoring data of obstacles on the moving trajectory of the left kiln door 4 or the right kiln door 7 to the control device 10 and the image recognition module successfully identifies the obstacles, and the alarm module generates sound and light alarm prompts.

[0043] The working principle of this embodiment is as follows: when the rotary kiln is stopped for maintenance, the existing kiln head burner is first controlled to withdraw from the kiln head burner bushing 13, and the door opening command is input through the control device 10. The control device 10 reads the feedback data of the safety detection probe 5. After judging that the working condition meets the safe door opening condition, the automatic locking device 6 is unlocked and reset, that is, the auxiliary linear actuator inside it is closed and drives the inclined limit block to move downward, releasing the limit on the first locking buckle 14. Then, the linear actuator 1 corresponding to the left kiln door 4 and in the open state is closed, and the corresponding hinge mechanism 2 is driven by the linear actuator 1, and then the left kiln door 4 is driven to open. Similarly, the linear actuator 1 corresponding to the right kiln door 7 and in the open state is closed, and the hinge mechanism 2 is pulled by the linear actuator 1, and then the right kiln door 7 is driven to open. During this period, the two linear actuators 1 will feed back the working status to the control device 10 in real time. Once the pressure or current is abnormal, the switch action will be stopped immediately and an alarm will be issued;

[0044] After the inspection is completed, the door closing command is input through the control device 10, the linear actuator 1 corresponding to the right kiln door 7 is opened, and the linear actuator 1 pulls the hinge mechanism 2, which then drives the right kiln door 7 to close, and the linear actuator 1 corresponding to the left kiln door 4 is opened, and the linear actuator 1 drives the corresponding hinge mechanism 2, which then drives the left kiln door 4 to close;

[0045] After the right kiln door 7 and the left kiln door 4 are combined and closed, the automatic locking device 6 is activated, the first locking buckle 14 is locked and stabilized, so that the kiln door is close to the kiln door installation surface 9. Fig.13 As shown, after the right kiln door 7 and the left kiln door 4 are closed, a labyrinth sealing structure is formed between the right kiln door 7 and the left kiln door 4, and a kiln door sealing device 17 is arranged on the left kiln door 4, and the sealing filler inside the kiln door 17 can block the gap between the right kiln door 7 and the left kiln door 4 to prevent air leakage and material leakage;

[0046] By comparing Fig.12 The traditional track sliding door shown is different from the sliding door attached to the outer wall of the kiln head cover. The intelligent kiln door has its own door frame and is tightly sealed. It will not deform due to high temperature, ensuring a good sealing effect. Fig.11 Compared with the traditional embedded double-leaf kiln door shown in the figure, the intelligent kiln door adds a prime mover and two constraints. The opening and closing trajectory of the kiln door is determined, and the safety is high. The intelligent kiln door can be automatically locked after closing, while the traditional kiln door usually needs to be locked manually, which is time-consuming and labor-intensive. In addition, the height above the kiln door is high, the working space is small and the risk factor is high.
