Description

Technical Field

[0001] The utility model relates to the technical field of kiln pressure regulation, in particular to a kiln combustion pressure regulation mechanism for improving the pressure relief accuracy. Background Technique

[0002] During the operation of the kiln, the internal pressure will gradually increase. In order to prevent the kiln from being unable to withstand the pressure, a pressure regulation device is installed on the kiln to control the internal pressure of the kiln.

[0003] According to the observation of the prior art, during the adjustment process, it is controlled by a control valve. By rotating the handle of the control valve, when the handle rotates, it can open the size of the valve, thereby playing a regulating function. However, the baffle of the valve is fixed by the friction force on the rotating rod. If the pressure is too large and pushes the valve baffle to move, the size of the valve opening cannot be accurately controlled, which will affect the heat retention and release inside the kiln during operation, and further affect the quality of the product production and processing inside the kiln.

It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0020] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model.

[0021] The following describes a kiln furnace combustion pressure regulating mechanism for improving pressure relief accuracy provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0022] Combined with Figures 1-3 As shown, a kiln furnace combustion pressure regulating mechanism for improving pressure relief accuracy provided by the present utility model includes a valve body 1. A sleeve 2 is fixedly connected to the top of the valve body 1. A rotating rod 3 is rotatably connected through the center position of the sleeve 2. One end of the rotating rod 3 is fixedly connected to a rotating handle 4. A cavity is provided at one end of the rotating handle 4. A rotating rod 5 is fixedly connected to the inner wall of the rotating handle 4. One end of the rotating rod 5 is rotatably connected to a rotating ring 6. A driving bevel gear 7 is fixedly connected to one side of the rotating ring 6. A driven bevel gear 8 is meshed and connected to the side of the driving bevel gear 7. A threaded rod 9 is fixedly connected to the center position at the bottom of the driven bevel gear 8. One end of the threaded rod 9 is threadedly connected through a threaded block 10. A connecting rod 11 is fixedly connected to one side of the threaded block 10. One end of the connecting rod 11 is fixedly connected to a fixing block 13;

[0023] One end of the connecting rod 11 is slidably connected through a limiting rod 12. One end of the limiting rod 12 is fixedly connected to a second connecting plate 21. The second connecting plate 21 is arranged in an L shape. One end of the second connecting plate 21 is fixedly connected to the bottom of the rotating handle 4. One end of the rotating rod 3 is fixedly connected to a blocking plate 24. The side wall of the blocking plate 24 is slidably attached to the inner wall of the valve body 1. Connecting rings 22 are fixedly connected to both ends of the valve body 1. A scale block 23 is fixedly connected to the top of the sleeve 2.

[0024] First Embodiment: When adjusting the rotary handle 4 and making one end of the rotary handle 4 point to the coordinates of the scale block 23, rotate the rotating ring 6. When the rotating ring 6 rotates, it can drive the driving bevel gear 7 to rotate. When the driving bevel gear 7 rotates, it can drive the driven bevel gear 8 to rotate. When the driven bevel gear 8 rotates, it can drive the threaded rod 9 to rotate. When the threaded rod 9 rotates, it can drive the threaded block 10 to move. When the threaded block 10 moves, it can drive the fixed block 13 on the connecting rod 11 into the fixing plate 19 in the arc groove 20, so as to ensure that the rotary handle 4 is fixed and will not move. When the pressure acts on the blocking plate 24 during pressure relief, it can ensure that the rotating rod 3 will not rotate, thus ensuring the stability during pressure relief, ensuring the accuracy of pressure relief, and then ensuring the normal adjustment of the pressure in the kiln, and further ensuring the quality of product production and processing.

[0025] The fixed block 13 is provided with a hollow interior. The inner wall of the fixed block 13 is symmetrically and fixedly connected with a fixing mechanism. The fixing mechanism includes a first connecting plate 14. One side of the first connecting plate 14 is fixedly connected with a spring telescopic rod 15. One end of the spring telescopic rod 15 is fixedly connected with an extrusion frame 16. One side of the extrusion frame 16 is fitted and slidably connected with a friction wheel 17. The central position of the friction wheel 17 is fixedly connected with a rotating shaft 18. The two ends of the rotating shaft 18 are rotatably connected to the inner wall of the fixed block 13. The side wall of the friction wheel 17 is fitted and slidably connected with a fixing plate 19. The two ends of the fixing plate 19 are fixedly connected with an arc groove 20. One side of the arc groove 20 is fixedly connected to the outer wall of the sleeve 2.

[0026] Second Embodiment: When the fixed block 13 enters the fixing plate 19, the friction wheel 17 will be extruded. Since the friction wheel 17 is made of a flexible material, it will produce a certain deformation. Subsequently, the friction wheel 17 will enter the groove in the fixing plate 19, and form a limit through the friction between the surface of the friction wheel 17 and the inner wall of the groove, so as to ensure the stability of the fixed block 13 and avoid the fixed block 13 moving and hitting the fixing plate 19 during the pressure relief process. The flexible friction wheel 17 has a certain shock absorption effect, thus ensuring the service life of the parts.

[0027] Working principle and usage process of the utility model: By adjusting the rotation handle 4 to drive the rotation rod 3 to rotate, when the rotation rod 3 rotates, it can drive the blocking plate 24 to move. When the blocking plate 24 moves, it can open the sealed valve body 1 to release pressure. The pressure release accuracy can be controlled by the pointing end of the rotation handle 4 and the scale block 23. After adjustment, by controlling the rotation of the rotation ring 6, when the rotation ring 6 rotates, it can drive the driven bevel gear 8 on the driving bevel gear 7 to rotate. When the driven bevel gear 8 rotates, it can drive the threaded rod 9 to rotate. The threaded rod 9 drives the threaded block 10 to move. When the threaded block 10 moves, it can drive the fixing block 13 on the connecting rod 11 to enter the fixing plate 19. When entering, the friction wheel 17 on the fixing block 13 will enter the groove of the fixing plate 19, and then use the friction force to form a limit. Moreover, the friction wheel 17 made of flexible material can also play a role in shock absorption.

The scope of the present utility model is defined by the claims and their equivalents.
