Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] This embodiment provides an air supply device for a pyrolysis furnace, which is more conducive to external staff to determine and judge the air supply status in the air supply duct. Specifically, Figure 1-5As shown, it includes a blower 1, a fixing frame 2, a hollow plastic ball 3, a mounting frame 4, a pressure sensor 5 and an alarm 6. The air inlet and the air outlet of the blower 1 are respectively provided with an air inlet duct 11 and an air outlet duct 12. The surface of the air outlet duct 12 is penetrated with a through-port 121. The fixing frame 2 is arranged on the surface of the air outlet duct 12 and is located directly above the through-port 121. The top surface and the front surface of the fixing frame 2 are penetrated with a through-port 21 and a slot 22 respectively. Both sides of the fixing frame 2 are provided with convex plates 23. The surfaces of the two convex plates 23 are provided with two connecting members 24. The hollow plastic ball 3 is located in the fixing frame 2. The mounting frame 4 includes a connecting plate 1 41 and a connecting plate 2 42 that are connected to each other. The surface of the connecting plate 1 41 is penetrated with two through-ports 3 43, and through the two through-ports 3 43 is arranged between the outer sides of the two connecting members 24, the connecting plate 2 42 is located in the fixed frame 2, and a space is left between the outer side surface of the connecting plate 2 42 and the inner side surface of the fixed frame 2, the pressure sensor 5 is installed on the connecting plate 2 42, and the model of the pressure sensor 5 is JHHM-H1, the alarm 6 is installed on the connecting plate 1 41, and the model of the alarm 6 is LTE-1101J, and the alarm 6 is connected with the pressure sensor 5 by electrical signals, so that during the ventilation process of the air outlet duct 12, part of the wind energy enters the fixed frame 2 through the port 1 121, so that the hollow plastic ball 3 moves upward in the fixed frame 2, so that it is always located above the pressure sensor 5, so that the ventilation state in the duct is monitored in real time through the cooperation of the pressure sensor 5 and the alarm 6.

[0027] like Figure 1-5 As shown, in this embodiment, the connecting member 24 includes a spring steel sheet 241, which is arranged on the surface of the convex plate 23. The surface of the spring steel sheet 241 is provided with a convex block 2411, and the convex block 2411 is designed as a right-angled triangle structure. One side of the convex block 2411 contacts one side of the connecting plate 41, and the side of the spring steel sheet 241 away from the convex plate 23 protrudes to the outside of the connecting plate 41. There is a space between one side of the connecting plate 41 and one side of the fixed frame 2. One side of the fixed frame 2 is provided with two spring steel sheets 25, and the two spring steel sheets 25 are provided. One side of the protrusion 2411 protrudes between the connecting plate 41 and the fixed frame 2, and the two spring steel sheets 25 are both under pressure. A handle 44 is provided on the surface of the connecting plate 41, so that when the staff needs to separate the mounting frame 4 and the fixed frame 2, they can grasp and press the multiple spring steel sheets 241 at the same time, so that one side of the protrusion 2411 is away from the connecting plate 41, so that the connecting plate 41 loses the restriction of the protrusion 2411 and slides forward with the rebound of the spring steel sheet 25, and finally grasp the handle 44 to apply pressure outward to pull it out.

[0028] like Figure 3As shown, in this embodiment, a sealing strip 7 is provided on one side of the connecting plate 41, and the sealing strip 7 is located on the outside of the slot 22 opened by the fixed frame 2. One side of the sealing strip 7 is in close contact with the surface of the fixed frame 2, so that the sealing strip 7 can be effectively utilized to achieve a sealing effect on the slot 22, thereby avoiding a large amount of gas discharge during the air supply process.

[0029] like Figure 1-3 As shown, in this embodiment, a connection frame 8 is sleeved on the top of the outer side of the fixing frame 2 , and a filter screen 9 is provided on the inner side of the connection frame 8 to prevent foreign particles and debris from falling into the fixing frame 2 through the second opening 21 .

[0030] During the use of the above-mentioned pyrolysis furnace air supply device, the staff can first take out the mounting frame 4 from the fixed frame 2. After the mounting frame 4 is taken out, the blower 1 can be turned on to realize the air supply to the outside pyrolysis furnace. During the air supply process, the wind in the air outlet duct 12 can enter the fixed frame 2 through the opening 121, and realize the blowing effect on the hollow plastic ball 3, so that the hollow plastic ball 3 moves upward in the fixed frame 2, and is kept in the upper position in the fixed frame 2 under the action of strong wind. Then, the handle 44 can be grasped to insert the connecting plate 2 42 into the fixed frame 2 through the slot 22. During the insertion process, the spring steel sheet 1 241 enters the opening 3 43 opened by the connecting plate 1 41, and the inclined surface of the protrusion 2411 It contacts with the connecting plate 41 to achieve the squeezing effect on the spring steel sheet 241 until the sealing strip 7 is in close contact with the surface of the fixed frame 2, and the protrusion 2411 realizes the limiting effect between the mounting frame 4 and the fixed frame 2. When the connecting plate 42 is inserted into the fixed frame 2, the wind energy in the pipeline circulates through the space between the connecting plate 42 and the fixed frame 2, thereby achieving the blowing and pressurizing effect on the hollow plastic ball 3. If during the air supply process, an unexpected state occurs in the pipeline or the air supply device, resulting in the termination of the air supply, the hollow plastic ball 3 that loses the wind energy pressure moves downward and contacts with the pressure sensor 5. The alarm 6 that receives the pressure signal sends a light alarm, so that the external staff can discover the unexpected situation in time and deal with it.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
