Description

Technical Field

[0001] The present invention relates to the technical field of waste incineration equipment, and particularly to a multi-stage anti-blocking oil gun device. Background Art

[0002] During the waste incineration process, if the fuel burns insufficiently and the temperature in the incinerator is not high enough, a certain amount of oil is usually sprayed into the incinerator through an oil gun to increase the fire in the incinerator. However, the oil guns in the prior art have the following problems: First, one end of the oil gun needs to be inserted into the incinerator for a long time. Affected by the high temperature in the incinerator, coking is likely to occur at the oil outlet port of the oil gun. Once coking occurs and is not cleaned in time, it is likely to cause the oil gun to be blocked, affecting the oil outlet efficiency of the oil gun and unable to play a role in adjusting the fire in the incinerator; Second, the atomization efficiency of the oil droplets sprayed by the oil guns in the prior art is insufficient, the air distribution direction is single, and the use efficiency of the oil gun is low. Summary of the Invention

[0003] To solve the above problems, the present invention provides a multi-stage anti-blocking oil gun device that can prevent the oil gun from being blocked, can reduce the diameter of the atomized particles of the oil droplets sprayed by the oil gun, and can change the air distribution direction.

[0004] Technical solution of the present invention: A multi-stage anti-blocking oil gun device, comprising an incinerator body, an oil gun body connected to the incinerator body, a flow valve connected to the oil gun body, a wind direction control device connected to the oil gun body, and a controller. The wind direction control device includes a blower, an intake pipe connected to the blower, a conversion head element connected to the intake pipe, and a first rotating motor for driving the conversion head element to rotate. A limiting hole is provided on the incinerator body. The conversion head element includes a stator element and a rotor element. The stator element is fixedly connected to the intake pipe, and the rotor element is movably connected to the limiting hole. The stator element is provided with ventilation grooves, and the rotor element is provided with a plurality of ventilation holes. The ventilation grooves are circular rings, and the diameter of the ventilation holes is less than or equal to the width of the ventilation grooves. The positions of the ventilation holes correspond to the positions of the ventilation grooves respectively. The controller is electrically connected to the blower, the first rotating motor, and the flow valve. With the above technical solution, when oil needs to be injected into the oil gun, first, the controller controls the flow valve to be in an open state, and the oil flows from the oil gun body into the incinerator body. Then, the controller controls the blower to supply wind to the intake pipe. When the wind enters the conversion head element, since the conversion head element includes a stator element and a rotor element, the wind enters the ventilation holes of the rotor element from the ventilation grooves in the stator element. The rotor element is driven to rotate by the first rotating motor. Therefore, the positions of the ventilation holes will also change. Therefore, the wind force will finally be in a spiral shape, and the wind force will drive the oil ejected from the oil pipe body to change its position to a certain extent, thereby changing the spraying position of the oil, avoiding insufficient oil injection effect of the oil gun due to too single spraying position of the oil, and at the same time, the wind force provided by the conversion head element will also cool down the oil gun body, avoiding coking at the end of the oil gun body due to too high temperature of the oil gun body, thereby avoiding blockage of the oil gun body.

[0005] Further setting of the present invention: There are four wind direction control devices, and the conversion head elements on the four wind direction control devices are respectively located in the up, down, left, and right directions of the oil gun body. With the above technical solution, since the conversion head elements on the four wind direction control devices are respectively located in the up, down, left, and right directions of the oil gun body, the range of the wind ejected by the conversion head elements can be increased, and the oil ejected from the oil pipe body can be secondarily atomized in four directions, making the oil droplet particles finer. In addition, the oil pipe body can be cooled more comprehensively, avoiding coking and blockage at the end of the oil pipe body.

[0006] Further setting of the present invention: The diameter of one end of the ventilation hole close to the center of the incinerator is larger than the diameter of the end of the ventilation hole far from the center of the incinerator.

[0007] With the above technical solution, since the diameter of one end of the ventilation hole close to the center of the incinerator is larger than that of the end away from the center of the incinerator, the coverage range of the wind force ejected by the adapter element can be increased, and further the coverage range of the oil ejected by the oil gun body can be increased, thereby improving the adjustment efficiency of the oil gun body on the fire of the incinerator.

[0008] Further setting of the present invention: The oil gun body includes a main oil inlet pipe, a connecting sleeve connected to the main oil inlet pipe, a return spring piece connected between the main oil inlet pipe and the connecting sleeve, and a filter screen connected to the end of the main oil inlet pipe. The surface of the return spring piece is corrugated.

[0009] With the above technical solution, since the oil gun body includes a main oil inlet pipe, a connecting sleeve connected to the main oil inlet pipe, a return spring piece connected between the main oil inlet pipe and the connecting sleeve, and a filter screen connected to the end of the main oil inlet pipe, and the surface of the return spring piece is corrugated, by sliding the position of the connecting sleeve, the overall length of the return spring piece is shortened, and the thickness of the return spring in the oil gun body will increase. This will increase the overall pressure in the oil gun body, thereby reducing the particle diameter of the oil droplets ejected by the oil gun body and further improving the adjustment efficiency of the oil gun body on the fire of the incinerator.

[0010] Further setting of the present invention: It further includes a water mist feeding device. The water mist feeding device includes a water inlet tank, a pressure pump connected to the water inlet tank, a water inlet pipe connected to the pressure pump, and a nozzle element connected to the water inlet pipe. The nozzle element is located above the oil gun body, and the nozzle element is directly below the adapter element. The pressure pump is electrically connected to the controller.

[0011] With the above technical solution, the controller controls the pressure pump to press the water in the water inlet tank into the nozzle element through the water inlet pipe, and then the formed water mist enters the incinerator. Since the nozzle element is located above the oil gun body and the nozzle element is directly below the adapter element, the water mist will adhere to the surface of the oil gun body under the influence of wind force. The water mist can absorb the heat at the end of the oil gun body to avoid coking and blocking at the end of the oil gun body. When the water droplets are vaporized again under the influence of high temperature, they will absorb the heat on the oil gun body again, further avoiding blockage of the oil gun body.

[0012] Further setting of the present invention: The nozzle element includes a device housing, a water inlet static joint connected to the device housing, a water inlet moving joint movably connected to the incinerator body, and a second rotating motor for driving the water inlet moving joint to rotate. The water inlet pipe is connected to the water inlet static joint. The water inlet moving joint is provided with a water outlet hole. The water inlet static joint and the water inlet moving joint are respectively provided with a first flow channel and a second flow channel. The second flow channel is respectively communicated with the first flow channel and the water outlet hole. The water inlet pipe is communicated with the first flow channel. The device housing is coaxially arranged with the oil gun body.

[0013] With the above technical solution, the controller controls the second rotating motor to drive the water inlet moving joint to rotate. Since the first flow groove and the second flow groove are respectively provided on the water inlet static joint and the water inlet moving joint, the second flow groove is respectively communicated with the first flow groove and the water outlet hole, and the water inlet pipe is communicated with the first flow groove. The water in the water inlet pipe will be sprayed out rotatably through the water outlet hole on the water inlet moving joint, so as to ensure that the sprayed water mist can be more comprehensively attached to the end of the oil gun body, avoid the coking phenomenon caused by the local high temperature at the end of the oil gun body, and further avoid the blockage of the oil gun.

Detailed Description of the Embodiment

[0019] Such as Figures 1-4As shown in the figure, a multi-stage anti-blocking oil gun device includes an incinerator body 1, an oil gun body 2 connected to the incinerator body 1, a flow valve 3 connected to the oil gun body 2, a wind direction control device 4 connected to the oil gun body 2, and a controller 5. The wind direction control device 4 includes a blower 6, an intake pipe 7 connected to the blower 6, a conversion head element 8 connected to the intake pipe 7, and a first rotary motor 9 for driving the conversion head element 8 to rotate. A limit hole 10 is provided on the incinerator body 1. The conversion head element 8 includes a stator element 11 and a rotor element 12. The stator element 11 is fixedly connected to the intake pipe 7, and the rotor element 12 is movably connected to the limit hole 10. A ventilation groove 13 is provided on the stator element 11, and a plurality of ventilation holes 14 are provided on the rotor element 12. The ventilation groove 13 is annular, the diameter of the ventilation hole 14 is less than or equal to the width of the ventilation groove 13, and the positions of the ventilation holes 14 correspond to the positions of the ventilation groove 13 respectively. The controller 5 is electrically connected to the blower 6, the first rotary motor 9, and the flow valve 3 respectively.

[0020] When oil needs to be fed into the oil gun, first, the controller 5 is used to control the flow valve 3 to be in an open state, and the oil flows from the oil gun body 2 into the incinerator body 1. Then, the controller 5 is used to control the blower 6 to supply wind to the intake pipe 7. When the wind enters the conversion head element 8, since the conversion head element 8 includes a stator element 11 and a rotor element 12, the wind enters the ventilation holes 14 of the rotor element 12 from the ventilation groove 13 in the stator element 11. The rotor element 12 is driven to rotate by the first rotary motor 9. Therefore, the positions of the ventilation holes 14 will also change. Therefore, the wind force will finally be in a spiral shape, and the wind force will drive the oil sprayed from the oil pipe body to change its position to a certain extent, thereby changing the spraying position of the oil, avoiding insufficient oil feeding effect of the oil gun due to overly single spraying position of the oil, and at the same time, the wind force provided by the conversion head element 8 will also cool the oil gun body 2, avoiding coking at the end of the oil gun body 2 due to too high temperature of the oil gun body 2, thereby avoiding blockage of the oil gun body 2.

[0021] The number of the wind direction control devices 4 is four, and the conversion head elements 8 on the four wind direction control devices 4 are respectively located in the up, down, left, and right directions of the oil gun body 2.

[0022] Since the conversion head elements 8 on the four wind direction control devices 4 are respectively located in the up, down, left, and right directions of the oil gun body 2, the range of the wind sprayed by the conversion head element 8 can be increased, and the oil sprayed from the oil pipe body can be secondarily atomized in four directions, making the oil droplet particles finer. In addition, the oil pipe body can be cooled more comprehensively, avoiding coking and blockage at the end of the oil pipe body. The diameter of one end of the ventilation hole 14 close to the center of the incinerator is larger than the diameter of the end of the ventilation hole 14 far from the center of the incinerator.

[0023] Since the diameter of the ventilation hole 14 at one end closer to the center of the incinerator is larger than the diameter of the ventilation hole 14 at one end farther from the center of the incinerator, the coverage range of the wind force ejected by the adapter element 8 can be increased, and further the coverage range of the oil ejected by the oil gun body 2 can be increased, thereby improving the adjustment efficiency of the oil gun body 2 on the fire of the incinerator.

[0024] The oil gun body 2 includes a main oil inlet pipe 15, a connecting sleeve 16 connected to the main oil inlet pipe 15, a return spring piece 17 connected between the main oil inlet pipe 15 and the connecting sleeve 16, and a filter screen 18 connected to the end of the main oil inlet pipe 15. The surface of the return spring piece 17 is corrugated.

[0025] Since the oil gun body 2 includes a main oil inlet pipe 15, a connecting sleeve 16 connected to the main oil inlet pipe 15, a return spring piece 17 connected between the main oil inlet pipe 15 and the connecting sleeve 16, and a filter screen 18 connected to the end of the main oil inlet pipe 15, and the surface of the return spring piece 17 is corrugated, by sliding the position of the connecting sleeve 16, the overall length of the return spring piece 17 is shortened, and the thickness of the return spring in the oil gun body 2 will increase. This will increase the overall pressure in the oil gun body 2, thereby reducing the particle diameter of the oil droplets ejected by the oil gun body 2 and further improving the adjustment efficiency of the oil gun body 2 on the fire of the incinerator.

[0026] It further includes a water mist feeding device 19. The water mist feeding device 19 includes a water inlet tank 20, a pressure pump 21 connected to the water inlet tank 20, a water inlet pipe 22 connected to the pressure pump 21, and a nozzle element 23 connected to the water inlet pipe 22. The nozzle element 23 is located above the oil gun body 2. The nozzle element 23 is directly below the adapter element 8. The pressure pump 21 is electrically connected to the controller 5.

[0027] The controller 5 controls the pressure pump 21 to press the water in the water inlet tank 20 into the nozzle element 23 through the water inlet pipe 22, and then the formed water mist enters the incinerator. Since the nozzle element 23 is located above the oil gun body 2 and the nozzle element 23 is directly below the adapter element 8, the water mist will adhere to the surface of the oil gun body 2 under the influence of the wind force. The water mist can absorb the heat at the end of the oil gun body 2 to avoid coking and blocking at the end of the oil gun body 2. When the water droplets are vaporized again under the influence of high temperature, they will absorb the heat on the oil gun body 2 again to further avoid blocking of the oil gun body 2.

[0028] The nozzle element 23 includes a device housing 24, a static water inlet joint 25 connected to the device housing 24, a dynamic water inlet joint 26 movably connected to the incinerator body 1, and a second rotary motor 27 for driving the dynamic water inlet joint 26 to rotate. The water inlet pipe 22 is connected to the static water inlet joint 25. The dynamic water inlet joint 26 is provided with water outlet holes 28. The static water inlet joint 25 and the dynamic water inlet joint 26 are respectively provided with a first flow groove 29 and a second flow groove 30. The second flow groove 30 is respectively communicated with the first flow groove 29 and the water outlet holes 28. The water inlet pipe 22 is communicated with the first flow groove 29. The device housing 24 is coaxially arranged with the oil gun body 2. The controller 5 controls the second rotary motor 27 to drive the dynamic water inlet joint 26 to rotate. Since the static water inlet joint 25 and the dynamic water inlet joint 26 are respectively provided with the first flow groove 29 and the second flow groove 30, and the second flow groove 30 is respectively communicated with the first flow groove 29 and the water outlet holes 28, and the water inlet pipe 22 is communicated with the first flow groove 29, the water in the water inlet pipe 22 will be sprayed out rotationally through the water outlet holes 28 on the dynamic water inlet joint 26. In this way, it can be ensured that the sprayed water mist can more comprehensively adhere to the end of the oil gun body 2, avoiding the coking phenomenon caused by the local high temperature at the end of the oil gun body 2, and further avoiding the blockage of the oil gun.
