[0023] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the automatic regulating device for heating air of a coke oven of the utility model in conjunction with the accompanying drawings.

[0024] like Figure 1-7 As shown, the utility model of the automatic regulating device for heating air of the coke oven comprises an air cover plate 1, which is arranged on the air inlet 7 of the coke oven, and is connected to the trigger 3 through an regulating column 2, one end of the regulating column 2 is connected to the air cover plate 1, and the other end is connected to the lower part of the trigger 3, and the trigger 3 can control the size of the opening and closing gap of the air cover plate 1 through the regulating column 2, thereby controlling the amount of air entering the air inlet 7 of the coke oven, and an regulating scale 21 is marked on the regulating column 2, and the regulating scale 21 helps the operator to observe and control the size of the gap of the air cover plate 1 more intuitively and quantitatively, and a rotating shaft 4 is connected to the middle and lower part of the trigger 3, one end of the rotating shaft 4 passes through the trigger 3, and the other end passes through the trigger 3. The two are rotatably connected, and the rotating shaft 4 can be used as a central fulcrum to enable the handle 3 to rotate around the rotating shaft 4 when an external force acts. The other end of the rotating shaft 4 is fixed on the furnace column 71, and a reinforcing rib plate 41 is provided at the fixed end of the rotating shaft 4 and the furnace column 71. The reinforcing rib plate 41 makes the connection between the rotating shaft 4 and the furnace column 71 more secure and prevents the sinking and displacement of the rotating shaft 4. The upper end of the trigger 3 is connected to the pull rod 5, and the trigger 3 is slidably connected to the pull rod 5 and the adjusting column 2. The pull rod 5 is mounted on the outer wall of the furnace column 71 through the corresponding pull rod bracket 51. The trigger 3 rotates left and right around the rotating shaft 4 under the drive of the pull rod 5, thereby driving the adjusting column 2 at its lower end to adjust the opening and closing gap of the air cover 1.

[0025] The air cover 1 includes a plate frame 11, a fixed cover 12 and an adjusting cover 13, all of which are rectangular. The plate frame 11 corresponds to the air inlet 7 of the coke oven. The air cover 1 is fixedly installed at the air inlet 7 of the coke oven through the plate frame 11. The fixed cover 12 and the adjusting cover 13 are both embedded in the inner side of the plate frame 11. The fixed cover 12 is fixed to one side in the plate frame 11. One edge of the fixed cover 12 is open, and the remaining edges are integrally formed with the side wall corresponding to the plate frame 11 and fixedly connected. The fixed cover 12 is connected to the bottom of the corresponding side wall of the plate frame 11. The fixed cover 12 makes the inner side of the plate frame 11 on its installation side appear in a closed style. This end is the closed end of the plate frame 11, and the other corresponding side in the plate frame 11 is open, which is the open end of the plate frame 11. The area of ​​the adjusting cover 13 is not less than the area of ​​the open end of the plate frame 11. A guide groove 111 is provided on the side wall around the inner side of the plate frame 11 above the fixed cover 12. A guide protrusion 112 corresponding to the guide groove 111 of the plate frame 11 is provided on the side wall around the outer side of the adjusting cover 13. The guide protrusion 112 corresponds to the guide groove 111 of the plate frame 11, and the two are slidably connected. The guide protrusion 112 can slide in the guide groove 111, so that the adjusting cover 13 can move between the closed end and the open end of the plate frame 11, thereby controlling the amount of air entering the coke oven through the gap between the adjusting cover 13 and the plate frame 11. One end of the adjusting column 2 is connected to the upper end surface of the corresponding side of the adjusting cover 13 and the open end of the plate frame 11, as shown in FIG. Figure 4 As shown, the left side of the air cover 1 is a closed end, and the right side is an open end. The adjusting column 2 is connected to the middle position of the right side of the upper end surface of the adjusting cover 13. When the adjusting column 2 moves toward the open end of the plate frame 11 in the forward direction, a guide ring 14 corresponding to the adjusting column 2 is arranged above the side of the plate frame 11 corresponding to the adjusting column 2. The guide ring 14 is fixedly connected to the plate frame 11, and the adjusting column 2 passes through the guide ring 14. While the guide ring 14 provides a guiding effect for the adjusting column 2, the gap size between the adjusting cover 13 and the corresponding side of the plate frame 11 can be simply and intuitively observed through the adjustment scale 21 corresponding to the guide ring 14, so that it is easier to adjust the size of the gap between the two as needed, so that the air intake adjustment of the air cover 1 becomes quantitative and easier to control.

[0026] The trigger 3 includes a support column 31 in the middle, an upper slide plate 32 is arranged above the support column 31, and a lower slide plate 33 is arranged below the support column 31. The three are arranged in parallel, the upper end of the support column 31 is fixedly connected to the lower end of the upper slide plate 32, and the lower end of the support column 31 is fixedly connected to the upper end of the lower slide plate 33. A vertical slide groove 34 that passes through the upper and lower slide plates 32 and 33 is provided. The upper and lower ends of the slide groove 34 are both closed to prevent the pin 35 or pin 36 passing through the middle from falling off from the slide groove 34, thereby affecting the operation of the entire device. The pull bar 5 is connected with a pin 35 at the corresponding position of the slide groove 34 of the upper slide plate 32. One end of the pin 35 is fixedly connected to the pull bar 5, and the other end thereof passes through the slide groove 34 of the upper slide plate 32 and is connected to the corresponding nut. The pin 35 can slide up and down in the slide groove 34 of the upper slide plate 32. The pin 35 moves left and right with the action of the pull rod 5, and the upper slide plate 32 drives the trigger 3 to swing left and right around the rotating shaft 4. The rotating shaft 4 is connected to the middle and lower part of the support column 31, and the two are perpendicular to each other. The connecting end of the rotating shaft 4 and the trigger 3 passes through the support column 31 and is rotatably connected to the support column 31. The end of the adjusting column 2 connected to the trigger 3 is provided with a fixing ring 22. The adjusting column 2 is connected to the trigger 3 through the fixing ring 22. The fixing ring 22 is slidably connected to the sliding groove 34 of the lower slide plate 33 through a pin 36. The pin 36 passes through the fixing ring 22 and the sliding groove 34 of the lower slide plate 33 in turn and is tightened and connected with the corresponding nut, thereby connecting the adjusting column 2 and the trigger 3 together. When the upper slide plate 32 on the upper part of the trigger 3 swings left and right under the action of the pull rod 5, the lower slide plate 33 on the lower part of the trigger 3 performs a corresponding left and right swinging action, thereby driving the adjusting column 2 to move left and right.

[0027] like Figure 8 As shown, for a double-connected coke oven, a trigger 3 is arranged between its single and double air inlets 7, and the left and right adjusting columns 2 can be connected in series through a pin 36 on the slide slot 34 at the lower end of the trigger 3, and the other end of each adjusting column 2 is respectively connected to the air cover 1 of the corresponding air inlet 7. An auxiliary adjusting column 23 is added to the two adjusting columns 2. Unlike the adjusting column 2, the other end of the auxiliary adjusting column 23 is connected to the upper end surface of the corresponding side of the closed end of the adjusting cover 13 and the plate frame 11, and the guide ring 14 corresponding to the auxiliary adjusting column 23 is arranged above the corresponding side of the plate frame 11 in the forward direction when the auxiliary adjusting column 2 moves toward the closed end of the plate frame 11, so that a trigger 3 can simultaneously control the air cover 1 on the single and double air inlets 7, so that they are opened and closed synchronously, so that the air intake of the single and double air inlets 7 is the same.

[0028] like Figure 1-7As shown, a coke oven is generally composed of a plurality of groups of air inlets 7, and a plurality of corresponding triggers 3 can be provided as needed. The lower end of each trigger 3 is provided with a corresponding one or a corresponding pair of adjustment columns 2 and an air cover 1. The plurality of triggers 3 are connected together in series through a pull rod 5, so that one pull rod 5 can simultaneously control the air intake of a plurality of groups of coke oven air inlets 7.

[0029] The pull rod bracket 51 includes a fixed wheel 511 and a bracket body 512. The bracket body 512 is fixedly connected to the furnace column 71. The fixed wheel 511 is installed at the outer end of the bracket body 512. The fixed wheel 511 is a "U"-shaped groove fixed wheel 511. The pull rod 5 is arranged in the wheel groove of the fixed wheel 511. The fixed wheel 511 serves as a sliding track for the pull rod 5. The pull rod bracket 51 provides support for the pull rod 5 to prevent the pull rod 5 from sinking or displacement.

[0030] A control device 6 is provided at the end of the pull rod 5, and the control device 6 can be used to control the pull rod 5 to move forward or backward along its track direction. The control device 6 includes a hydraulic cylinder 61 with a telescopic rod 62. The telescopic rod 62 is parallel to the pull rod 5, and the top of the telescopic rod 62 is fixedly connected to the end of the pull rod 5. A hydraulic pump 63 is provided at the bottom of the hydraulic cylinder 61. The hydraulic cylinder 61 can be controlled by the hydraulic pump 63 to drive the telescopic rod 62 to perform telescopic action. The pull rod 5 moves left and right with the extension and retraction of the telescopic rod 62, thereby driving the handle 3 on the pull rod 5 to swing left and right around its rotating shaft 4, thereby making the gap of the air cover 1 larger or smaller under the drive of the corresponding adjustment column 2. The control device 6 is fixedly connected to the furnace column 71 through a support frame 64 fixedly connected thereto. The support frame 64 provides support for the control device 6 to prevent it from sinking or displacement. The hydraulic pump 63 of the control device 6 is connected to the corresponding computer system, and the hydraulic pump 63 can be controlled by the computer system.

[0031] When in use, first select the number of the trigger 3 and the adjusting columns 2 and air cover 1 below it according to the style of the coke oven and the number of its air inlets 7, set the pull rods 5 of corresponding lengths, and connect the trigger 3 in series to the corresponding pull rods 5. At this time, the automatic regulating device for heating air in the coke oven of the utility model can be used. The hydraulic pump 63 can be controlled by the corresponding computer system according to the needs of the coke oven. The working process of the hydraulic pump 63 can be preset in the system, or the operation of the hydraulic pump 63 can be directly controlled, thereby controlling the extension and retraction of the telescopic rod 62 on the hydraulic cylinder 61, and then controlling the swing of the trigger 3 through the pull rod 5, and finally adjusting the gap of the air cover 1 through the adjusting column 2. When the adjusting cover 13 is completely moved to the open end of the plate frame 11, the air cover 1 is in a closed state as a whole. At this time, air cannot enter the coke oven through the air inlet 7. As the adjusting cover 13 gradually moves toward the closed end of the plate frame 11, a gap gradually appears between it and the plate frame 11. The gap moves with the adjusting cover 1 3 gradually increases, and as the gap increases, the air can enter the coke oven through the air inlet 7. When the regulating cover 13 is completely moved to the closed end of the plate frame 11 and above the fixed cover 12, the air cover 1 is in a fully open state. At this time, the air inlet 7 is in a state where the maximum amount of air can enter the coke oven. The air cover 1 is fully opened. When it is necessary to reduce the amount of air intake, the regulating cover 13 is controlled to gradually move from the closed end of the plate frame 11 to the open end, narrowing the gap between the regulating cover 13 and the side of the plate frame 11 corresponding to the open end, thereby reducing the amount of air entering the coke oven through the air inlet 7. When the regulating cover 13 is completely moved to the open end of the plate frame 11, the air cover 1 is in a closed state again, and air can no longer enter the coke oven through the air inlet 7. The automatic regulating device for coke oven heating air of the utility model achieves the purpose of controlling the amount of air entering the coke oven by controlling the mutual movement of the regulating cover 13 at the closed end and the open end of the plate frame 11.

[0032] The utility model discloses an automatic regulating device for heating air of coke oven, which changes the regulation of the opening of air inlet doors at 7 places of the air inlet of coke oven from the original manual regulation to automatic regulation through mechanical device, and no longer needs manual remote transport of air cover plate and then high-altitude operation, thus realizing remote computer-controlled regulation, improving the safety factor of workers, reducing the time required for regulation, and making it possible to timely regulate the environmental protection index of the waste gas of coke oven, which is more conducive to the workers' control over the coke oven and its waste gas emission, and more conducive to environmental protection.
