[0002] With the continuous advancement of industrial technology, automation has become an important feature of modern industrial production. In a coking plant, the automation level of the coke oven directly determines the efficiency and quality of the entire coking production line. Coke oven automation is not only related to product productivity, but also closely linked to production costs. The improvement of the automation level of the coke oven means the reduction of manual intervention in the production process and the enhancement of machine intelligence. By introducing advanced control systems and automation equipment, the coke oven can more accurately control key parameters such as temperature, pressure and time, thereby improving the quality and output of coke. In addition, the introduction of the automation system can also reduce human operating errors, avoid safety hazards in the production process, and ensure the stable operation of the production line.

[0003] During the production process of coke oven equipment, the light beam emitted by the fiber optic transmitter in the code plate recognition system in harsh environments such as rain, fog, snow, excessive dust and smoke will encounter fog, rain, snow, smoke, dust and other particles in the atmosphere. These particles will scatter the light. The more particles there are in the atmosphere, the stronger the scattered light, the weaker the received light intensity or the light cannot be received at all, which ultimately causes the automatic alignment system to fail to correctly identify the code plate or fail to identify the code plate.

[0008] Furthermore, the solenoid valve is installed at the air compressor and the inlet of the purge pipeline.

[0009] Furthermore, a visual recognition unit is provided inside the reading head for selecting different purge modes according to the current state of the reading head.

[0010] Furthermore, the air compressor selects manual or automatic mode to start and stop the solenoid valve through a PLC program to achieve a purging effect.

[0011] Furthermore, the purge air hole is inside the reading head, and the particles in the atmosphere are purged by blowing out the high-pressure gas from the air compressor.

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0027] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0029] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0030] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0031] like Figure 1 to Figure 2 As shown, the utility model provides a purge device installed on the automatic alignment reading head of the coke oven equipment, characterized in that it includes: an air compressor, an air storage tank, a purge pipeline 1, a solenoid valve, and a purge air hole 2;

The solenoid valve is installed at the inlet of the air compressor purge pipeline 1, and the purge air hole 2 is located in the reading head 3.

[0033] Furthermore, the automatic alignment system of the coke oven equipment is composed of a code plate recognition system and a positioning code plate. The reading head 3 is located at the front end of the code plate recognition system, and the positioning code plate is fixed at the target position. A set of binary coding holes and a set of clock holes are drilled on the positioning code plate. When the equipment decelerates and runs to 200 mm away from the target position according to the speed curve set in the program, it slowly enters the positioning code plate area. At this time, some of the light beams emitted by the six optical fiber transmitters with different functions arranged in the reading head 3 will not be able to reach the reading head 3 due to the obstruction of the code plate, causing different changes in the state of the optical fiber sensor. The changed state is input into the PLC to correspond to the current furnace number value.

[0034] Furthermore, the solenoid valve is installed at the inlet of the air compressor and the purge pipeline 1.

[0035] Furthermore, a visual recognition unit is provided inside the reading head for selecting different purge modes according to the current state of the reading head.

[0036] Furthermore, the air compressor selects manual or automatic mode to start and stop the solenoid valve through a PLC program to achieve a purging effect.

[0037] Furthermore, the reading head 3 is provided with 8 purge air holes 2 inside.

[0038] Furthermore, the purge air hole 2 is inside the reading head 3 and purges particles in the atmosphere by blowing out high-pressure gas from the air compressor.

[0039] Furthermore, a code plate recognition system is installed in the reading head 3 to identify the furnace number value of the current equipment.

[0040] Furthermore, a visual recognition unit 4 is provided inside the reading head for selecting different purge modes according to the current state of the reading head.

[0041] Furthermore, in the automatic mode, the user can confirm the actual equipment working environment according to the visual recognition unit 4 and set the timed purge or pre-recognition purge by himself.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
