Description

Technical Field

[0001] This utility model relates to the field of coking technology, specifically to a coke cake temperature detection device based on infrared colorimetric thermometry, used to monitor the transverse temperature, center temperature and overall temperature distribution of the coke cake in real time during the coking process. Background Technology

[0002] In the coking process of a coke oven, accurate detection of coke cake temperature is crucial for optimizing the heating process and improving coke quality. Traditional temperature detection methods often use single-point or a small number of temperature probes, which are insufficient to comprehensively reflect the temperature distribution of the coke cake, especially with technical bottlenecks in high-precision detection of the center temperature. Furthermore, the high temperature and dusty environment of a coke oven makes existing temperature measuring devices susceptible to environmental interference, leading to data distortion. Insufficient probe installation stability and poor gas path sealing further affect long-term reliable operation.

[0003] Therefore, there is an urgent need for a temperature detection device that can cover multiple areas of the coke cake, has strong anti-interference capabilities, and is securely installed, in order to solve the shortcomings of existing technologies such as large detection blind spots, low accuracy, and difficult maintenance.

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a coke oven cake temperature detection device. Through distributed probe layout, modular installation structure and efficient sealing design, it solves the problems of large detection blind spots, low accuracy and poor environmental adaptability of traditional methods. It significantly improves the comprehensiveness of temperature detection (covering the upper, middle, lower and central areas of the coke cake), stability (installation accuracy ±1mm) and anti-interference ability (temperature measurement error <±2℃). It is suitable for fine temperature monitoring and control in the coke oven pushing process.

[0006] 2. Technical Solution:

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A coke oven cake temperature detection device, comprising:

[0009] Seven sets of infrared colorimetric temperature probes are used. Six sets are symmetrically installed on the brackets on the left and right sides of the coking grid, with three sets on each side located at the upper, middle, and lower positions, respectively, to detect the lateral temperature of the coke cake. The seventh set is installed on the dust cover opposite the outlet of the coking grid to detect the center temperature of the coke cake.

[0010] An embedded processing host is electrically connected to the infrared colorimetric temperature probe, and its output is connected to a wireless transmission module through a signal transmitting device.

[0011] A cooling air pump is connected to the infrared colorimetric temperature probe via an air pipe assembly;

[0012] The probe bracket includes a support plate welded to the wall panel of the coke blocking vehicle and a mounting base. The support plate is a steel plate or channel steel with a thickness of 1cm, a width of 10cm and a length of 13cm. The mounting base is a steel plate with a thickness of 1cm, a width of 5cm and a length of 10cm and two holes, which is vertically welded to one side of the support plate.

[0013] The three-dimensional adjustment frame is fixed to the mounting base by bolt assembly, and the infrared colorimetric temperature probe is connected to the three-dimensional adjustment frame through a flange.

[0014] The distribution box is welded to the steel plate frame or angle iron of the coke quenching car and fixed with bolts;

[0015] The dust cover passes through a 7cm diameter observation hole in the wall panel of the coke quenching vehicle and connects to the three-dimensional adjustment frame;

[0016] The galvanized gas pipe assembly includes a tee connector and a four-way connector. One end of the tee connector is connected to the cooling gas pump outlet hose, and the other end is connected to the upper probe galvanized gas pipe, the middle probe galvanized gas pipe, and the lower probe galvanized gas pipe respectively through the four-way connector. The cable passes through the additional port of the tee connector and is fixed by the locking head.

[0017] A further improvement is that the three-dimensional adjustment frame is connected to the flange of the infrared colorimetric temperature probe by three sets of bolts, with washers added to the bolt heads, and the thread direction of the three-dimensional adjustment frame matches that of the bolts.

[0018] A further improvement is that the welding edge between the support plate and the coke chute wall plate is a side edge with a width of 10cm, and the welding edge of the mounting base is a side edge with a length of 10cm and is far away from the opening side of the base.

[0019] A further improvement is that the steel plate frame of the distribution box is a 2.5mm thick welded steel plate, or it can be directly welded to the coke quenching car using perforated angle iron.

[0020] A further improvement is that the additional opening of the tee joint of the galvanized gas pipe assembly is filled with sealant, and the cable passes through a high-temperature resistant pipe and a locking head into the main control box or distribution box.

[0040] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0041] I. Component Installation Steps

[0042] 1. Install the probe bracket 2

[0043] step:

[0044] Weld a support plate 11 (preferably channel steel) with a thickness of 1cm, a width of 10cm and a length of 13cm to the bracket 2 at the designated position on the coke chute wall panel, ensuring that the welding edge is a side edge with a width of 10cm.

[0045] The mounting base 12 (1cm thick, 5cm wide, 10cm long, with two holes) is vertically welded to the unwelded side of the support plate 11, with the welding edge being a 10cm long side edge away from the opening side of the base.

[0046] Effects: Provides a stable installation base, has strong vibration resistance, and ensures long-term stable operation of the probe.

[0047] 2. Fix three-dimensional adjustment frame 14

[0048] step:

[0049] The three-dimensional adjustment bracket 14 is attached to the side of the mounting base 12 away from the wall panel and fixed by the bolt 16 assembly. The thread direction matches the bolt to avoid reverse screwing.

[0050] A washer is added to the head of bolt 16 to prevent the bolt from loosening due to the large inner hole.

[0051] The three-dimensional adjustment frame 14 includes adjustment bolts in the X, Y and Z directions. The spatial position of the infrared colorimetric temperature probe 1 can be finely adjusted by rotating the bolts, with an adjustment accuracy of ±1 mm.

[0052] Effect: Enables precise fine-tuning of the probe's spatial position (accuracy ±1mm), adapting to different working conditions.

[0053] 3. Assemble an infrared colorimetric temperature probe 1

[0054] step:

[0055] An observation hole 13 with a diameter of 7cm is made directly opposite the dust cover 17 on the wall panel of the coke chute.

[0056] Pass the probe through the dust cover 17 and the observation hole 13, and align its flange 15 with the three-dimensional adjustment frame (14).

[0057] The flange 15 is connected to the three-dimensional adjustment frame 14 by three sets of bolts 16, forming a "three-push and three-pull" structure to ensure that the probe is firmly fixed.

[0058] Effects: The dust cover 17 blocks more than 90% of dust, extending the probe's service life; the flange connection structure is vibration-resistant, avoiding displacement errors.

[0059] 4. Install 61 galvanized gas pipe assemblies

[0060] step:

[0061] Connect one end of the cooling air pump outlet hose 62 to the three-way connector 64, and the other end is branched through the four-way connector 63 to the upper probe air tube 632, the middle probe air tube 631, and the lower probe air tube 633.

[0062] Insert the cable through the additional port of the tee connector 64, secure the cable with the metal locking head 65, and fill with high-temperature resistant sealant to ensure airtightness.

[0063] The cable is fitted with a red high-temperature resistant tube and a galvanized flexible tube, and then crimped with terminals or crystal heads after passing through the main control box or distribution box.

[0064] Effects: The gas path is isolated from the circuit to prevent gas leakage from interfering with the temperature measurement accuracy (error < ±2℃); the high-temperature resistant tube protects the cable and reduces the impact of environmental heat radiation.

[0065] 5. Install the distribution box 4

[0066] step:

[0067] Weld a 2.5mm thick steel plate frame or perforated angle iron to the reserved position on the coke quenching car to ensure a smooth welding surface.

[0068] Attach the distribution box 4 to the steel plate frame or angle iron, align the fixing holes, and then tighten it with bolts 16.

[0069] Internally, connect the power cord, signal cord, and wireless transmission module according to the wiring diagram.

[0070] Benefits: Modular design supports quick assembly and disassembly, reducing maintenance difficulty; centralized circuit management avoids malfunctions caused by messy wiring.

[0071] II. Operational Procedure

[0072] 1. System startup

[0073] Turn on the cooling air pump, which delivers cooling gas to each infrared colorimetric temperature probe 1 through the galvanized air pipe assembly 61 to reduce the probe's operating temperature.

[0074] When the embedded processing host 3 is powered on, it automatically receives the temperature signal collected by the infrared colorimetric temperature probe 1.

[0075] 2. Temperature detection and data processing

[0076] Six sets of transverse infrared colorimetric temperature probes 1 detect the transverse temperature of the coke cake at three points (top, middle, and bottom) in real time, while a seventh set of central infrared colorimetric temperature probes 1 detects the central temperature of the coke cake.

[0077] The embedded processing host 3 filters, corrects, and averages the temperature data to generate a temperature distribution map.

[0078] 3. Data transmission and central control linkage

[0079] The processed temperature data is transmitted to the central control room via a wireless transmission module to guide operators in adjusting the coke oven heating parameters.

[0080] The central control system dynamically optimizes the coke pushing speed and heating strategy based on the temperature distribution.

[0081] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
