Description

Technical Field

[0001] This utility model relates to a quenching furnace, specifically a three-section continuous fluidized particle steel wire isothermal quenching furnace. Background Technology

[0002] The three-section continuous fluidized particle steel wire isothermal quenching furnace is a continuous quenching furnace, and fluidized particles can be added as a medium during the use of the quenching furnace. During the continuous heat treatment of the workpiece, the quenching oil used will evaporate at high temperature and mix with the harmful gases in the furnace.

[0003] Announcement No. CN221877107U proposes a continuous heat treatment quenching furnace. It utilizes an internal circulation fan to sequentially pass oil-containing gases within the furnace through high-temperature resistant oil-absorbing cotton located in each oil fume filter box, purifying and filtering the air inside the furnace and reducing the amount of harmful gases emitted. A motor drives a linkage rod to rotate, causing the front circular plate to rotate and move closer to the rear circular plate, causing the high-temperature resistant oil-absorbing cotton to be in a twisted state. This facilitates the expulsion of absorbed oil and fumes from the relevant pipes, solving the complex problem of handling oil fumes and harmful gases inside the quenching furnace.

[0004] However, during the implementation of this device, the device squeezes out the e-liquid through rotation and extrusion. However, due to the setting of the fan-shaped hole on the rear circular plate, the squeezed e-liquid will enter the rear of the rear circular plate, thus affecting the subsequent discharge of the e-liquid. To solve the above problem, a three-stage continuous fluidized particle steel wire isothermal quenching furnace is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies where squeezed-out e-liquid enters behind the rear circular plate, thus affecting subsequent discharge of e-liquid, this invention provides a three-stage continuous fluidized particle steel wire isothermal quenching furnace.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses a three-section continuous fluidized particle steel wire isothermal quenching furnace, comprising a quenching furnace body, a fixed frame fixedly connected to the surface of the quenching furnace body, a fixed tube fixedly connected to the surface of the fixed frame, fixed shells arranged at equal intervals fixedly connected to the surface of the fixed tube, a fixed plate fixedly connected inside the fixed shells, a sliding plate slidably connected inside the fixed shells, high-temperature resistant oil-absorbing soft cotton provided between the sliding plate and the fixed plate, a rotating rod slidably connected inside the fixed tube and in contact with the inside of the fixed plate, the surface of the rotating rod being fixedly connected to the inside of the sliding plate, and a threaded rod threadedly connected inside the rotating rod.

[0008] As a preferred embodiment of this utility model, the surface of the sliding plate is fixedly connected to a limiting block that is slidably connected to the inside of the fixed shell.

[0009] As a preferred embodiment of this utility model, a stop bar is fixedly connected to the surface of the sliding plate, and a through hole corresponding to the stop bar is opened on the surface of the fixed plate.

[0010] As a preferred embodiment of this utility model, a motor is fixedly connected to the surface of the quenching furnace body, and the output end of the motor is fixedly connected to a threaded rod via a coupling.

[0011] As a preferred embodiment of this utility model, a discharge pipe is fixedly connected to the lower end of the fixed shell, and a ring plate is fixedly connected inside the discharge pipe.

[0012] As a preferred embodiment of this utility model, the discharge pipe is provided with a cone-shaped baffle plate inside.

[0013] As a preferred embodiment of this utility model, a sliding rod is fixedly connected to the surface of the shielding plate and slidably connected to the inside of the ring plate. A return spring is movably sleeved on the surface of the sliding rod, and the two ends of the return spring are fixedly connected to the sliding rod and the ring plate, respectively.

[0014] As a preferred embodiment of this utility model, a connecting rod is fixedly connected to the surface of the shield, and a trapezoidal fixing block is fixedly connected to the surface of the connecting rod.

[0015] The beneficial effects of this utility model are as follows: This three-section continuous fluidized particle steel wire isothermal quenching furnace, by starting the motor, causes the threaded rod to drive the rotating rod and the sliding plate, so that the sliding plate squeezes the high-temperature oil-absorbing cotton, removing the grease on the high-temperature oil-absorbing cotton, avoiding twisting of the high-temperature oil-absorbing cotton and reducing damage to the cotton. At the same time, the through holes are blocked, reducing the situation where grease enters behind the fixed plate, thereby reducing the situation where grease returns to the equipment after being blown by the fan.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model discloses a three-section continuous fluidized particle steel wire isothermal quenching furnace, including a furnace body 1. A fixed frame 7 is fixedly connected to the surface of the furnace body 1 to provide installation space for subsequent structures. A fixed pipe 5 for conveying oil fumes is fixedly connected to the surface of the fixed frame 7. Fixed shells 6, arranged at equal intervals to provide installation space for subsequent structures, are fixedly connected to the surface of the fixed pipe 5. A fixed plate 9 for passing oil fumes is fixedly connected inside the fixed shells 6. A sliding plate 11 for pushing and squeezing subsequent installation structures is slidably connected inside the fixed shells 6. A high-temperature resistant oil-absorbing soft cotton 10 is provided between the sliding plate 11 and the fixed plate 9 to absorb oil fumes. The high-temperature resistant oil-absorbing soft cotton 10 can absorb the oil fumes generated during processing. This will be described in a comparative example, therefore, it will not be further elaborated upon. The explanation is as follows: the fixed tube 5 has a sliding connection inside which a rotating rod 4 is driven for subsequent structures. The surface of the rotating rod 4 is in contact with the interior of the fixed plate 9. The surface of the rotating rod 4 is fixedly connected to the interior of the sliding plate 11. The rotating rod 4 has a threaded connection inside which a threaded rod 3 is driven. The surface of the sliding plate 11 has a fixed connection to a limiting block 12 that restricts the sliding plate 11. The surface of the limiting block 12 is slidably connected to the interior of the fixed shell 6. Through the restriction of the limiting block 12, the limiting block 12 blocks the sliding plate 11, thereby blocking the rotation of the rotating rod 4. As a result, when the threaded rod 3 rotates, the rotating rod 4 does not rotate with the threaded rod 3, but slides with the rotation of the threaded rod 3. Thus, the rotating rod 4 drives the sliding plate 11 to slide.

[0024] The quenching furnace equipment body 1 is started by a fan, which causes the oil fumes to circulate and be absorbed and filtered by the high-temperature resistant oil-absorbing cotton 10. This is described in the comparative case, so it will not be explained again.

[0025] A baffle 16 for sealing subsequent structures is fixedly connected to the surface of the sliding plate 11. A through hole 15 for oil fume to pass through is provided on the surface of the fixed plate 9, corresponding to the baffle 16. Figure 2 As can be seen, the fixed shell 6 has grooves to allow oil fumes to pass through normally.

[0026] A motor 2, which controls the operation of the device, is fixedly connected to the surface of the quenching furnace equipment body 1. The output end of the motor 2 is fixedly connected to the threaded rod 3 through a coupling.

[0027] The lower end of the fixed shell 6 is fixedly connected to an exhaust pipe 8 for discharging e-liquid. Inside the exhaust pipe 8, an annular plate 17 is fixedly connected to provide installation space for subsequent structures. Inside the exhaust pipe 8, a baffle plate 19 is provided to block subsequent structures. The baffle plate 19 is conical. A sliding rod 18 for connecting subsequent installation structures is fixedly connected to the surface of the baffle plate 19. The sliding rod 18 is slidably connected to the inside of the annular plate 17. A return spring 20 for controlling the sliding rod 18 is movably sleeved on the surface of the sliding rod 18. The two ends of the return spring 20 are fixedly connected to the sliding rod 18 and the annular plate 17, respectively. A connecting rod 13 for providing installation space for subsequent structures is fixedly connected to the surface of the baffle plate 19. A fixing block 14 for pushing the connecting rod 13 is fixedly connected to the surface of the connecting rod 13. The fixing block 14 is trapezoidal.

[0028] When cleaning the e-liquid on the high-temperature absorbent cotton 10 during operation, the operator starts the motor 2. The output end of the motor 2 drives the threaded rod 3 to rotate. The threaded rod 3 drives the rotating rod 4. Under the obstruction of the limiting block 12, the rotating rod 4 slides as the threaded rod 3 rotates, thereby driving the sliding plate 11 to slide. The sliding plate 11 slides and squeezes the high-temperature absorbent cotton 10, causing the e-liquid to flow out. At the same time, the sliding plate 11 drives the baffle 16 to move, so that the baffle 16 inserts into the through hole 15 and seals the through hole 15.

[0029] When the sliding plate 11 slides, it presses against the inclined surface of the fixed block 14, which in turn pushes the connecting rod 13. The connecting rod 13, under pressure, slides and pushes the baffle plate 19, causing the baffle plate 19 to no longer contact the ring plate 17, thus no longer blocking the exhaust pipe 8. This allows the compressed e-liquid to be discharged through the exhaust pipe 8. At the same time, the baffle plate 19 drives the sliding rod 18 to move, which compresses the return spring 20. When the fixed block 14 is no longer pressed, the baffle plate 19 returns to its original position under the elastic force of the return spring 20, blocking the exhaust pipe 8 again. This prevents the e-liquid from entering the exhaust pipe 8 during the oil fume circulation process, thereby reducing the amount of oil fume discharged to the outside.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
