[0026] As Figure 1 The utility model embodiment provides a coal loading car with ignition function, which mainly includes car body 1 and coal supporting plate 4 and ignition device 6 respectively arranged on car body 1.

[0027] Among them, coal supporting plate 4 is used for bearing coal cake 3 and can move to the door of carbonization chamber 2 with car body 1, and coal supporting plate 4 can move relative to car body 1 to move the bearing coal cake 3 into carbonization chamber 2 or move out of carbonization chamber 2.

[0028] Ignition device 6 is located at the bottom of one end of coal supporting plate 4 close to the entrance of carbonization chamber 2, and is used for igniting the escaped raw gas in carbonization chamber 2.

[0029] The car body 1 of the coal charging car of the embodiment is provided with an ignition device 6 at the bottom of the end of the coal supporting plate 4 close to the inlet of the carbonization chamber 2, and the escaping raw gas in the carbonization chamber 2 is ignited through the ignition device 6, which can effectively prevent the continuous overflow of raw gas and reduce the emission of toxic and harmful gases and particulate matters.

[0030] In some embodiments, the car body 1 is provided with a supporting roller 5 supporting the coal supporting plate 4, and the coal supporting plate 4 can slide into or out of the carbonization chamber 2 under the support of the supporting roller 5. The car body 1 is provided with a driving mechanism (not shown in the figure) connected with the coal supporting plate 4, which can be used to drive the coal supporting plate 4 to move on the supporting roller 5. The connection mode of the driving mechanism and the coal supporting plate 4 belongs to the prior art and will not be described in detail.

[0031] In some embodiments, the ignition device 6 provided on the car body 1 is a plasma ignition device. The flame jet port of the plasma ignition device faces the inlet of the carbonization chamber 2, and the flame jet port of the plasma ignition device can ignite the raw gas escaping from the carbonization chamber 2. The plasma ignition device has high ignition energy and fast response speed, can quickly and reliably ignite the raw gas overflowing from the coal cake 3 in the carbonization chamber 2, greatly improves the success rate and stability of ignition. At the same time, the plasma ignition device has good adaptability and durability, can stably operate in a complex coke oven environment and is not easily disturbed by external factors. The single-point flame has a larger jet area and is more fully contacted with the raw gas, thereby effectively solving the problem that the raw gas cannot be effectively collected at the open door part of the carbonization chamber 2 during the alternating operation of the coal charging car and the coke pushing car, and greatly reducing the unorganized escape.

[0032] The plasma ignition device of the embodiment mainly consists of a plasma generator, a direct current power supply, an ignition burner, a control system and the like. The specific structure and working principle thereof belong to the prior art and will not be described in detail.

[0033] In addition, the car body 1 of the coal charging car also has a 220V power supply for connecting the plasma ignition device.

[0034] In some embodiments, the car body 1 is provided with a water storage tank 10 and a circulating water pump 9, the water outlet of the circulating water pump 9 is connected with the cooling water inlet of the ignition device 6, the cooling water outlet of the ignition device 6 is connected with the water inlet of the water storage tank 10, and the water outlet of the water storage tank 10 is connected with the water inlet of the circulating water pump 9.

[0035] The water storage tank 10 stores cooling water. Since the electric arc in the plasma ignition device occurs between the anode and cathode, the anode and cathode generate a large amount of heat under the influence of high current. Therefore, the circulating water pump 9 continuously injects the cooling water from the water storage tank 10 into the cooling water inlet of the ignition device 6 to cool the anode and cathode, preventing burn-out and deformation, and extending their service life. The pressure of the cooling water pumped by the circulating water pump 9 is above 0.3 MPa, and the flow rate is above 10 t / h, ensuring that the temperature of the anode and cathode in the plasma ignition device remains below 40℃.

[0036] Preferably, the water storage tank 10 can be used to store desalinated water.

[0037] In some embodiments, the vehicle body 1 is further provided with an air tank 11, which is connected to the air inlet of the plasma ignition device through a compressed air pipeline. The air tank 11 can provide carrier air to the plasma ignition device through the compressed air pipeline.

[0038] In some embodiments, a solenoid valve 12 may be provided on the compressed air pipeline. The solenoid valve 12 can be started or closed according to the command signal, thereby quickly completing the air supply and air closure actions of the compressed air pipeline.

[0039] In some embodiments, the plasma ignition device has an air inlet on the flame tube (not shown in the figure), which is close to the opening of the flame tube. The air tank 11 is also connected to the air inlet. The angle between the axis of the air inlet and the axis of the flame tube is an acute angle. The compressed air in the air tank 11 can enter the flame tube through the air inlet and be discharged through the flame tube. This can prevent external dust from accumulating in the flame tube and affecting the normal use of the device.

[0040] like Figure 1 As shown, in some embodiments, the coal loading car body 1 may also be equipped with a control room 7 and a control cabinet 8 located within the control room 7. A water storage tank 10, a circulating water pump 9, and an air storage tank 11 are respectively located on one side of the control room 7. The control cabinet 8 can be connected to the ignition device 6, the circulating water pump 9, and the solenoid valve 12, etc. Operators can start or stop the ignition device 6 and adjust parameters such as the cooling water and compressed air flow rates through the control cabinet 8 within the control room 7 to adapt to different working requirements.

[0041] In addition, the water tank 10, circulating water pump 9, air tank 11 and control room 7 are all located on the vehicle body 1, which makes it convenient for operators to observe on-site whether there is enough water in the water tank 10 and whether the pressure in the air tank 11 is within the normal range.

[0042] Preferably, the pipes connecting the circulating water pump 9 with the ignition device 6 and the compressed air pipes connecting the air tank 11 with the ignition device 6 are made of high-strength and corrosion-resistant materials, which can be used stably for a long time in harsh working environments to ensure that they will not be damaged or leak during long-term use.

[0043] Since the coal supporting plate 4 is used to support the compacted coal cake 3, and the vehicle body 1 will shake during the loading of the coal cake 3. In some embodiments, the plasma ignition device is connected with the vehicle body 1 through an elastic member for shock absorption (not shown in the figure). When the vehicle body 1 shakes, the plasma ignition device can be shock-absorbed through the elastic member.

[0044] In some embodiments, the front end of the plasma ignition device, i.e., the end close to its flame port, can be connected with the vehicle body 1 through an elastic member, and the rear end of the plasma ignition device, i.e., the end away from its flame port, can be movably connected with the vehicle body 1. In this way, not only the stability of the ignition device on the vehicle body 1 can be ensured to prevent the gun head from falling off during the running of the coal loading vehicle, but also the shock absorption effect can be achieved to prevent the internal components from being damaged. Preferably, the rear end of the plasma ignition device can be connected with the vehicle body 1 through a metal soft rope, so as to facilitate the installation and disassembly of the plasma ignition device.

[0045] For example, a fixed shaft can be arranged on the vehicle body 1, and the rear end of the plasma ignition device can be connected with the fixed shaft through a metal soft rope.

[0046] In some embodiments, the end of the vehicle body 1 opposite to the inlet of the carbonization chamber 2 is provided with two supporting wheels 5 arranged at intervals, which can be used to support the coal supporting plate 4, and the plasma ignition device is arranged between the two supporting wheels 5.

[0047] The shape and size of the plasma ignition device can be flexibly selected according to actual conditions to ensure that it can play the best plasma emission effect in different working scenarios. For example, in a relatively narrow space, a small and exquisite plasma ignition device with strong plasma emission capacity can be selected; and in a relatively open space, a larger plasma ignition device can be selected to expand the range of plasma emission.

[0048] The use method of the coal loading vehicle of the present embodiment will be described in detail as follows:

[0049] Preparation work: The operator enters the control room 7, and in the control room 7, the system of the entire coal loading vehicle can be checked and initialized by the control cabinet 8. This includes confirming whether each component is operating normally, such as whether the rotation of the supporting wheel 5 at the bottom of the coal supporting plate 4 is flexible, whether the circulating water pump 9 is working normally, etc.

[0050] Coal loading process: the vehicle body 1 moves to the position of the coal cake 3, and the coal loading equipment is operated through the control cabinet 8 to place the coal cake 3 on the coal supporting plate 4. The supporting wheel 5 serves to support and assist the movement of the coal supporting plate 4, ensuring that the coal cake 3 can be stably placed on the coal supporting plate 4 and balanced during the movement of the coal loading vehicle. The coal loading vehicle moves to the corresponding position of the carbonization chamber 2 with the coal cake 3.

[0051] Carbonization chamber 2 operation: the operator in the control room 7 controls the mechanical structure of the coal loading vehicle through the control cabinet 8 to make the coal supporting plate 4 slowly send the coal cake 3 into the carbonization chamber 2. This process requires precise control of speed and position to prevent damage or position deviation of the coal cake 3.

[0052] Process auxiliary operation: after the coal cake 3 slowly enters the carbonization chamber 2, the coal supporting plate 4 is slowly retracted, and after complete retraction, the ignition operation is performed through the plasma ignition device, the air storage tank 11 is used to provide carrier air to the ignition device 6, the electromagnetic valve 12 on the compressed air pipeline can quickly complete the air supply and air closing action according to the command signal, and the plasma is emitted, and the circulating water pump 9 can be started as needed to prevent damage to the equipment due to high temperature. The water in the water storage tank 10 provides water source for the circulating water pump 9. The operation of the plasma ignition device can be remotely controlled in the control room 7 through the control cabinet 8 to ensure the safety of the operator.

[0053] Subsequent monitoring and operation: during the carbonization process, the operator can observe the temperature, raw gas emission, and other parameters in the carbonization chamber 2 through the control cabinet 8 and related monitoring equipment in the control room 7, and make adjustments according to the actual situation. For example, if the temperature is too high, the cooling intensity can be increased through the circulating water pump 9; if a large amount of raw gas is emitted during carbonization, the air volume of the air storage tank 11 can be increased, and the electromagnetic valve 12 on the compressed air pipeline can quickly complete the air supply and air closing action according to the command signal to emit a large amount of plasma.

[0054] The above description is intended to be illustrative and not limiting, and those of ordinary skill in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more aspects thereof) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
