Description

A slag removal device and method for a slag crusher Technical Field

[0001] This application relates to the field of equipment maintenance technology, and mainly to a slag removal device and method for a slag crusher. Background Technology

[0002] During operation, coal-fired boilers are prone to producing coke lumps due to factors such as fuel characteristics, combustion conditions, and boiler structure. These coke lumps can affect the boiler's thermal efficiency and stable operation. A slag crusher can pre-crush the slag discharged from the bottom of the furnace to intercept large coke lumps and perform pre-cooling and pre-crushing, thereby improving the boiler's operating efficiency and stability. However, slag can easily adhere to the outlet of the slag crusher, causing blockages. Therefore, a slag removal device is needed to help remove the attached slag.

[0003] Although the inventors know of an automatic control rapping slag removal device that has achieved a certain degree of automation, its operating efficiency, stability and environmental performance are limited due to the lack of precise frequency control, intelligent feedback system and multi-dimensional sensors, which leads to increased equipment wear.

[0010] S3: The control unit analyzes sensor data, determines the current slag removal status, and adjusts the vibration intensity based on the amount of slag adhered.

[0011] S4: After the rapping is completed, the control terminal automatically evaluates the slag removal effect and repeats the rapping process if necessary until the slag removal is detected to be complete. Attached Figure Description

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this application. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Example 1, referring to Figures 1 and 2, is the first embodiment of this application. This embodiment provides a slag removal device for a slag crusher, including a monitoring component 100, a control terminal 200 electrically connected to the monitoring component 100, and a rapping structure 300 electrically connected to the control terminal 200. The monitoring component 100 monitors the temperature of the slag discharge channel of the slag crusher in real time to determine the operating status of the equipment, including the equipment temperature and the amount of slag accumulation inside the equipment. The monitoring structure also monitors the vibration, pressure, and slag adhesion of the slag crusher and transmits the data to the control terminal 200. The control terminal 200 uses the data transmitted by the monitoring structure to control the rapping frequency of the rapping structure 300 in real time to improve the slag removal efficiency and extend the equipment life.

[0020] Specifically, based on the equipment specifications, working conditions and slag characteristics, the vibration frequency, amplitude and pressure parameters are preset. The monitoring component 100 will monitor the operation of the slag crusher in real time, and the control terminal 200 will use the data transmitted by the monitoring structure to control the vibration frequency of the vibration structure 300 in real time.

[0021] The beneficial effects of this application are as follows: By incorporating technologies such as sensors, intelligent feedback systems, and automatic adjustment and control algorithms, the problems of inaccurate rapping force and frequency, rapid equipment wear, high dust pollution, and high energy consumption in the existing technology are solved, thereby improving slag removal efficiency, extending equipment life and enhancing operational stability. At the same time, energy consumption and environmental risks are reduced, and the overall efficiency of industrial slag removal operations is improved.

[0022] Example 2, referring to Figures 1-2, is the second embodiment of this application. Unlike the previous embodiment, as shown in Figure 2, k-1 is the outlet support of the crusher, k-2 is the bottom of the outlet channel of the crusher, and the monitoring component 100 includes a temperature sensor 101, a vibration sensor 102, and a pressure sensor 103. The temperature sensor 101 is located on the side of the slag outlet of the crusher and is electrically connected to the control terminal 200. The sensor monitors the temperature, vibration, pressure, and slag adhesion in real time and transmits the data to the control terminal 200. The temperature sensor 101 is installed around the outlet channel of the crusher to monitor the temperature of the equipment during operation to prevent the equipment from overheating and affecting the slag removal effect.

[0023] In one embodiment, the rapping structure 300 includes an installation ring 301 disposed at the bottom of the slag discharge channel of the crusher. A pneumatic hammer 302 is disposed on the inner wall of the installation ring 301. A vibrating plate 303 is disposed on the side of the pneumatic hammer 302. The vibrating plate 303 is in contact with the slag discharge channel of the crusher. An air pump is externally connected to the pneumatic hammer 302. The air pump is connected to a control terminal 200. The control terminal 200 can adjust the air delivery frequency of the air pump to adjust the rapping frequency.

[0024] In one embodiment, a vibration sensor 102 is disposed on the side of the pneumatic hammer 302 and electrically connected to the control terminal 200. The vibration sensor 102 is installed on the support structure near the rapping hammer and on the slag crusher outlet bracket to detect the vibration intensity and frequency during the rapping process in real time and provide feedback on the rapping effect. A pressure sensor 103 is disposed on the top of the pneumatic hammer 302 and electrically connected to the control terminal 200. The pressure sensor 103 is installed on the key support of the equipment and on the vibrating plate to detect the residue adhesion strength and equipment load, and to prevent damage to the equipment from excessive rapping.

[0025] Specifically, the slag crusher outlet is the main channel for residue discharge, where high-temperature residue or dust adheres and gradually accumulates. Sensors detect the distribution and thickness of the residue, providing accurate data on slag removal requirements. A pneumatic hammer 302 is installed in the slag crusher outlet area to vibrate and dislodge nearby residue. The supporting structure here must be robust enough to withstand the high-frequency vibrations generated by the vibration; therefore, installing a vibration sensor 102 effectively monitors the vibration intensity. Near the dry slag crusher outlet, key supports and fixing components need to withstand the impact of vibration and residue; these locations significantly affect the vibration effect and equipment stability.

[0026] Example 3, referring to Figures 1-2, is the third embodiment of this application. Unlike the previous embodiment, this embodiment provides a slag removal method, which includes the slag discharge device of a slag crusher described above, and further includes:

[0027] S1: Preset vibration frequency, amplitude, and pressure parameters;

[0028] S2: Monitors the structure's vibration, pressure, and temperature in real time and transmits the data to the control terminal 200;

[0029] S3: The control terminal 200 analyzes sensor data, determines the current slag removal status, and adjusts the vibration intensity according to the amount of slag attached.

[0030] S4: After the rapping is completed, the control terminal 200 automatically evaluates the slag removal effect and repeats the rapping process if necessary until the slag removal is detected to be complete.

[0031] In one embodiment, the monitoring structure monitors vibration, pressure, and temperature in real time and transmits the data to a control terminal 200, including:

[0032] T1: Temperature sensor 101 monitors the temperature of the equipment during operation to prevent overheating from affecting the slag removal effect;

[0033] T2: Vibration sensor 102 monitors the vibration intensity and frequency during the rapping process in real time and provides feedback on the rapping effect;

[0034] T3: Pressure sensor 103 monitors the amount of residue adhering and the equipment load in real time to prevent damage to the equipment from excessive vibration.

[0035] In one embodiment, the pressure sensor 103 monitors the amount of residue adhering to the equipment and the equipment load in real time to prevent damage to the equipment from excessive vibration, including:

[0036] X1: Pressure sensor 103 is installed on key supports and vibrating structures of the equipment to detect the adhesion strength of residue and the load on the equipment. The information is transmitted to control terminal 200, and control terminal 200 adjusts the rapping frequency.

[0037] X2: After the rapping is completed, the pressure sensor 103 detects the adhesion strength of the residue. If the cleaning is not completed, the rapping process is repeated until the residue removal is detected to be complete.

[0038] Specifically, sensor signals are combined with the control algorithm of the rapping system to form a feedback closed-loop system, which intelligently adjusts the rapping intensity and frequency. Based on sensor data (vibration, pressure, temperature, etc.), the rapping process is automatically optimized to achieve precise and efficient slag removal.

[0039] Real-time monitoring and alarm system: The system monitors signals from sensors via a data acquisition module. When abnormal vibration, excessive pressure, or other potential malfunctions occur, the system automatically issues an alarm and takes appropriate measures, such as adjusting the vibration frequency or stopping the equipment.
