[0002] In the production of foam ceramics, due to the process of foam ceramics, foam ceramics need to be supported and transported by kiln cars through a short-distance high-temperature zone in the tunnel kiln (the working temperature is generally 1100℃) for high-temperature firing, and then pass through a long-distance cooling zone (the working temperature is generally 700℃) for porcelain treatment. In order to cope with the firing of foam ceramics, the existing kiln structure usually has to be lengthened so that the kiln has a 700℃ cooling zone for foam ceramics porcelainization, making the total length of the kiln up to more than 900 meters. Such a kiln structure has very strict requirements on the plant site, and there is an unreasonable layout of the plant, resulting in low space utilization of the plant, causing increased investment and cost increases for the enterprise. In addition, the product turnover distance out of the kiln is long, affecting the production efficiency of foam ceramics. Summary of the invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0020] In the description of the present invention, it is to be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.
[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] Reference below Figures 1 to 6 A highly efficient and energy-saving rotary tunnel kiln provided according to an embodiment of the present invention is described.
[0023] like Figures 1 to 6As shown, the energy-efficient rotary tunnel kiln according to the embodiment of the present invention can be applied to the firing of foam ceramics. Without losing the firing temperature, the floor space requirement of the plant for the layout of the energy-efficient rotary tunnel kiln can be reduced, the turnover distance of the fired products out of the kiln can be shortened, the production efficiency can be improved, and the heat loss can be reduced to achieve energy saving and environmental protection.
[0024] The energy-efficient rotary tunnel kiln has a first direction, a second direction and an up-down direction, wherein the first direction, the second direction and the up-down direction are perpendicular to each other. In this embodiment, it is assumed that the first direction is the front-back direction and the second direction is the left-right direction.
[0025] The high-efficiency and energy-saving rotary tunnel kiln comprises a tunnel kiln body, a heat-insulating box 500, a heat-insulating wall, a translation device 600 and a push-pull device.
[0026] The structure of the tunnel kiln body includes a first kiln body 410 and a second kiln body 420. The length of the first kiln body 410 extends along the first direction, and the length of the second kiln body 420 also extends along the first direction. The first kiln body 410 and the second kiln body 420 are arranged side by side along the second direction. Moreover, the first kiln body 410 and the second kiln body 420 are both provided with an opening structure on the same side along the first direction.
[0027] It is understandable that the length dimensions of the first kiln body 410 and the second kiln body 420 may be the same or different. The spacing between the first kiln body 410 and the second kiln body 420 in the second direction may be zero, that is, the first kiln body 410 and the second kiln body 420 are arranged closely together, or may be non-zero. Both the first kiln body 410 and the second kiln body 420 have a kiln cavity capable of accommodating the kiln car 210, and the kiln cavity extends and penetrates along the first direction to form an opening of the kiln cavity. A high temperature zone of 1100°C may be arranged in the first kiln body 410, and a cooling zone of 700°C may be arranged in the second kiln body 420.
[0028] In this embodiment, the rear side of the first kiln body 410 and the rear side of the second kiln body 420 are both provided with an opening structure, and the size of the opening structure can allow the kiln car 210 to pass through. The kiln cavity opening located at the front side of the first kiln body 410 is the first inlet, the kiln cavity opening located at the rear side of the first kiln body 410 is the first outlet, the kiln cavity opening located at the rear side of the second kiln body 420 is the second inlet, and the kiln cavity opening located at the front side of the second kiln body 420 is the second outlet. Both the first outlet and the second inlet are opening structures. Then, the front end of the first kiln body 410 is the kiln head of the high-efficiency and energy-saving rotary tunnel kiln, and the front end of the second kiln body 420 is the kiln tail of the high-efficiency and energy-saving rotary tunnel kiln.
[0029] A first hydraulic propeller 100 is provided at the front side of the first inlet, and the first hydraulic propeller 100 is fixed on the ground. The function of the first hydraulic propeller 100 is to push the kiln car 210 from the kiln head into the kiln cavity. When the first hydraulic propeller 100 is working, the push head of the first hydraulic propeller 100 can slowly push the kiln car 210, so that the kiln car 210 carrying the foam ceramic blank 300 enters the first kiln body 410. The kiln car 210 coming out of the first kiln body 410 will enter the second kiln body 420 through the second inlet with the foam ceramic blank 300. When the kiln car 210 leaves the second kiln body 420 from the second outlet, the kiln car 210 reaches the kiln tail, and it is necessary to unload the fired foam ceramic products from the kiln car 210, so that the empty kiln car 210 can carry the foam ceramic blank 300 again and re-enter the first kiln body 410 from the kiln head.
[0030] It can be understood that the energy-efficient rotary tunnel kiln is divided into two sections as a whole, which can reduce the floor space of the energy-efficient rotary tunnel kiln in the first direction, reduce the floor space requirements of the energy-efficient rotary tunnel kiln for the factory building, and improve the space utilization rate of the factory building. Moreover, it can shorten the turnover distance of the foam ceramic products out of the kiln, so that the kiln car 210 can return to the kiln head faster after unloading the products and reload the foam ceramic blank 300. Then, the kiln car 210 brings the foam ceramic blank 300 into the energy-efficient rotary tunnel kiln to complete the firing work.
[0031] The heat preservation box 500 is located at one side of the first kiln body 410 along the first direction. The heat preservation box 500 is hollow inside to form a cavity. The shape and size of the cavity can meet the requirements of accommodating the kiln car 210. The opening of the cavity is open to the other side of the first kiln body 410 along the first direction. The heat preservation box 500 can move along the second direction relative to the first kiln body 410 and the second kiln body 420, so that the cavity of the heat preservation box 500 can be connected with the opening structure of the first kiln body 410, so that the kiln car 210 can be transferred from the first kiln body 410 to the heat preservation box 500, or connected with the opening structure of the second kiln body 420, so that the kiln car 210 can be transferred from the heat preservation box 500 to the second kiln body 420.
[0032] In this embodiment, the heat preservation box 500 is disposed at the rear side of the first kiln body 410 and the second kiln body 420. The heat preservation box 500 is in a cubic shape, and the opening of the cavity is open to the front side of the heat preservation box 500, and the opening of the cavity can allow the kiln car 210 to pass through. The heat preservation box 500 is made of heat preservation materials such as heat preservation bricks, etc., and the heat preservation box 500 has good heat preservation performance and can prevent heat from being lost.
[0033] Insulation walls are provided on both sides of the insulation box 500 along the second direction, and the insulation walls are connected to the insulation box 500, and the insulation walls can move together with the insulation box 500. The insulation walls are configured to cover the opening structure. It can be understood that the size of the insulation wall is larger than the size of the opening structure, and the insulation wall can block and seal the corresponding opening structure to prevent a large amount of heat energy from being lost through the opening structure.
[0034] In this embodiment, if Figure 3 , Figure 4 and Figure 6 As shown, there are two insulation walls, one of which is located on the right side of the insulation box 500, and is set as the first insulation wall 810. The first insulation wall 810 can shield the opening structure of the first kiln body 410; the other insulation wall is located on the left side of the insulation box 500, and is set as the second insulation wall 820. The second insulation wall 820 can shield the opening structure of the second kiln body 420.
[0035] It is understandable that when the heat preservation box 500 is docked with the first kiln body 410, the heat preservation box 500 can cover the opening structure of the first kiln body 410, and at the same time, the second heat preservation wall 820 covers the opening structure of the second kiln body 420; when the heat preservation box 500 is docked with the second kiln body 420, the heat preservation box 500 can cover the opening structure of the second kiln body 420, and at the same time, the second heat preservation wall 820 covers the opening structure of the first kiln body 410. Such a design can prevent a large amount of heat energy in the first kiln body 410 and the second kiln body 420 from being lost, thereby reducing the use of energy such as gas, and ensuring that the temperature fluctuation in the first kiln body 410 and the second kiln body 420 is small.
[0036] The translation device 600 is arranged at the bottom of the heat preservation box 500, and the heat preservation box 500 is fixed relative to the translation device 600. Moreover, the translation device 600 is configured to drive the heat preservation box 500 and the heat preservation wall to move along the second direction, so as to adjust the positions of the heat preservation box 500 and the two heat preservation walls relative to the first kiln body 410 and the second kiln body 420, so that the opening of the cavity is opposite to and connected with one of the opening structures, and the other opening structure is arranged opposite to the corresponding heat preservation wall. It can be understood that the translation device 600 can be a mobile trolley, which can carry the heat preservation box 500 to move along the second direction, so as to promote the heat preservation box 500 to accurately dock with the first kiln body 410 or the second kiln body 420.
[0037] In this embodiment, the structure of the translation device 600 includes a translation frame 610 and a translation drive mechanism. The heat preservation box 500 and the translation drive mechanism are both arranged on the translation frame 610. The translation frame 610 is provided with a support rail 690. The length of the support rail 690 extends along the first direction. There are two support rails 690. The function of the support rail 690 is to support the wheels of the kiln car 210. The translation drive mechanism is configured to drive the translation frame 610 to move along the second direction. Figure 5 As shown, the support rail 690 is in an I-shape, and the wheels of the kiln car 210 can roll on the support rail 690 .
[0038] It is understandable that double rails extending in the first direction are provided in both the first kiln body 410 and the second kiln body 420, so that the kiln car 210 can move linearly along the double rails. When the heat preservation box 500 is docked with the first kiln body 410 or the second kiln body 420, the two support rails 690 on the translation frame 610 can be connected with the double rails, so that the kiln car 210 can move stably between the support rails 690 and the double rails. The translation drive mechanism can be a hydraulic cylinder, a gear rack drive device, etc., as long as it can meet the requirements of driving the translation frame 610 to move linearly. In the case where the translation frame 610 is provided with the support rails 690, the cavity passes through the lower wall of the heat preservation box 500.
[0039] Further, such as Figures 3 to 6 As shown, the energy-efficient rotary tunnel kiln further includes a guide rail 640. There are at least two guide rails 640, all of which are arranged side by side along a first direction, and all of which extend along a second direction. The guide rails 640 can be installed in a ground tunnel.
[0040] A plurality of groups of first running wheels 630 are provided at the bottom of the translation device 600, and the plurality of groups of first running wheels 630 are arranged at certain intervals along the first direction. Moreover, the plurality of groups of first running wheels 630 are respectively rollingly connected to a plurality of guide rails 640, and each guide rail 640 is provided with a group of first running wheels 630. A second running wheel 840 is provided at the bottom of the insulation wall, and the second running wheel 840 is rollingly connected to the guide rail 640 close to the opening structure, so that the insulation wall can be arranged close to the opening structure and can cover the opening structure. By the first running wheel 630 rolling on the guide rail 640 and the second running wheel 840 rolling on the corresponding guide rail 640, the translation device 600 can drive the insulation box 500 and the insulation wall to move along the second direction, and the friction resistance of the movement is small.
[0041] In this embodiment, two groups of first running wheels 630 are provided, and each group of first running wheels 630 includes four first running wheels 630. Three second running wheels 840 are provided at the bottom of each insulation wall. The translation drive mechanism includes a rotation drive device 681 and a transmission structure 682, wherein the rotation drive device 681 includes a motor and a reducer, and the transmission structure 682 is a chain 623 transmission component, and the chain 623 transmission component is respectively connected to the reducer and one of the first running wheels 630, so that the motor drives the chain 623 transmission component to operate through the reducer, so that the chain 623 transmission component can drive the first running wheel 630 to rotate.
[0042] The push-pull device is disposed on the translation device 600 , and is configured to pull the kiln car 210 from the first kiln body 410 into the cavity, and push the kiln car 210 from the cavity into the second kiln body 420 .
[0043] It can be understood that the kiln cars 210 in the first kiln body 410 are moved backwards one by one. In order to prevent the kiln wall of the first kiln body 410 or the side wall of the heat preservation box 500 from being damaged by the obstruction of the kiln car 210 when the heat preservation box 500 moves along the second direction, a push-pull device is added to the translation device 600. When the heat preservation box 500 is docked with the first kiln body 410, the kiln car 210 located at the opening structure is pulled by the push-pull device to pull the kiln car 210 into the cavity of the heat preservation box 500, and the kiln car 210 is pulled away from the kiln car 210 located in front of it by a certain distance. Then, the heat preservation box 500 moves in a straight line toward the second kiln body 420 with the kiln car 210 driven by the translation device 600. When the heat preservation box 500 is docked with the second kiln body 420 , the kiln car 210 located in the cavity is pushed by the push-pull device to push the kiln car 210 into the second kiln body 420 .
[0044] In some embodiments, the push-pull device includes a first linear drive device, a second linear drive device and a force-applying head. Among them, a slot with an opening facing downward is provided at the bottom of the kiln car 210, and the first linear drive device and the second linear drive device can be a hydraulic cylinder, a cylinder, etc. The first linear drive device is provided on the translation device 600, and the output end of the first linear drive device is connected to the second linear drive device, which can drive the second linear drive device to move in the up and down directions, and the output end of the second linear drive device is connected to the force-applying head, which can drive the force-applying head to move in the first direction. Therefore, through the cooperation of the first linear drive device and the second linear drive device, the force-applying head can be inserted into the slot of the kiln car 210, and then, the kiln car 210 is subjected to a pulling force or a thrusting force through the force-applying head, so that the kiln car 210 can move in the first direction.
[0045] In other embodiments, the structure of the push-pull device includes a pulling mechanism and a pushing mechanism. The pulling mechanism and the pushing mechanism are both arranged on the translation device 600 and can move along the second direction following the translation device 600. Moreover, the pulling mechanism is configured to drive the kiln car 210 near the opening structure to move from the first kiln body 410 to the cavity, and the pushing mechanism is configured to drive the kiln car 210 located in the cavity to move to the second kiln body 420.
[0046] Specifically, Figure 2 and Figure 5 As shown, the pulling mechanism includes a translation seat 650, a hook 660, a first driving component and a second driving component. The first driving component is arranged on the translation device 600, and the first driving component is configured to drive the translation seat 650 to move along a first direction. The first driving component can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder or other linear driving devices.
[0047] In this embodiment, if Figure 2 and Figure 5 As shown, the structure of the first driving component includes a chain 623, a rotating driving member 621 and two sprockets 622. The chain 623 is wound between the two sprockets 622, and the two sprockets 622 are installed at opposite ends of the translation frame 610 along the first direction, and the chain 623 is fixedly connected to the translation seat 650. A plurality of rollers 651 are arranged on both sides of the bottom of the translation seat 650 along the second direction. Correspondingly, the translation frame 610 is provided with two guide rails 670 extending along the first direction, and the plurality of rollers 651 are respectively and correspondingly connected to the guide rails 670 in a rolling manner, so that the friction resistance of the movement of the translation seat 650 can be reduced, and the translation seat 650 can be stably moved along the first direction.
[0048] The rotary drive member 621 is disposed on the translation device 600, and the rotary drive member 621 is configured to drive the chain 623 to drive the translation seat 650 to move along the first direction. The rotary drive member 621 includes a drive shaft 625, a drive wheel 626, a reducer and a motor. The motor is connected to the drive shaft 625 through the reducer, the reducer is installed on the translation frame 610 through bolts, the drive shaft 625 is installed on the translation frame 610 through a bearing seat, the drive shaft 625 extends along the second direction, the drive wheel 626 is disposed on the drive shaft 625, and the chain 623 is meshed and connected with the drive wheel 626. Therefore, when the motor is running, the drive wheel 626 can drive the chain 623 to drive the translation seat 650 to move along the first direction.
[0049] Further, such as Figure 2As shown, the structure of the first driving component also includes a tension spring 624. One of the sprockets 622 is arranged on the translation device 600, and the sprocket 622 is set as a fixed wheel. Another sprocket 622 is movably arranged on the translation device 600, and the sprocket 622 is set as a movable wheel, and the sprocket 622 can move along the first direction relative to the translation device 600. The tension spring 624 extends along the first direction, one end of the tension spring 624 is fixedly connected to the translation frame 610, and the other end of the tension spring 624 is fixedly connected to the sprocket 622, and the tension spring 624 is configured to drive the two sprockets 622 away from each other to tension the chain 623.
[0050] Specifically, the movable wheel is mounted on the support plate, and the support plate is mounted on the translation frame 610 through bolts, the bolts can slide along the first direction relative to the translation frame 610, and the tension spring 624 is sleeved on the bolts, one end of the tension spring 624 abuts against the translation frame 610, and the other end abuts against the nut on the bolt. It can be understood that by screwing the nut to adjust the distance between the movable wheel and the fixed wheel, the chain 623 can be in a tensioned state.
[0051] The hook 660 is hinged to the upper part of the translation seat 650 through a hinge shaft, and the hinge axis of the hook 660 extends along the second direction, so that the hook 660 can swing relative to the translation seat 650. The second driving component is disposed on the translation seat 650, and the second driving component is configured to drive the hook 660 to rotate around the hinge axis, so that the hook 660 is engaged with or separated from the kiln car 210.
[0052] It can be understood that the second driving component can be a cylinder or a hydraulic cylinder, etc. The second driving component can drive the hook 911 to swing upward according to the working condition, so that the hook 911 can produce a clamping effect with the kiln car 210, so that the hook 911 can drag the kiln car 210 from the first kiln body 410 to the insulation box 500 during the movement with the translation seat 650, and can drive the hook 911 to swing downward according to the working condition, so that the hook 911 releases the clamping effect between it and the kiln car 210, so that the cart mechanism can push the kiln car 210 from the insulation box 500 to the second kiln body 420.
[0053] The first driving component is disposed at the bottom of the translation frame 610 to prevent the first driving component from being affected by high temperature and obstruction of the kiln car 210, and to facilitate the routing of the first driving component.
[0054] Specifically, Figures 1 to 3As shown, the pusher mechanism includes an auxiliary kiln car 220 and a third driving component. The heat preservation box 500 is provided with a bottom opening 510, which is located on the side of the heat preservation box 500 away from the opening structure. The bottom opening 510 and the opening of the cavity are arranged opposite to each other along the first direction, and the bottom opening 510 can allow the auxiliary kiln car 220 to pass through. The auxiliary kiln car 220 is movably arranged on the translation device 600, and the auxiliary kiln car 220 is partially located in the cavity. The function of the auxiliary kiln car 220 is to apply a thrust to the kiln car 210 located in the cavity, so as to push the kiln car 210 from the heat preservation box 500 to the second kiln body 420.
[0055] In this embodiment, the structure of the auxiliary kiln car 220 is consistent with that of the kiln car 210 . A support frame is disposed on the upper portion of the kiln car 210 , and the foam ceramic body 300 is placed on the support frame.
[0056] It is understandable that the auxiliary kiln car 220 can be installed on the translation device 600 through a slide rail and a slider pair. In addition, the bottom of the auxiliary kiln car 220 can also be provided with a running wheel, which can roll on the support rail 690. The auxiliary kiln car 220 is partially located in the cavity, and there is a small vertical spacing between the upper wall surface of the bottom opening 510 and the auxiliary kiln car 220, which can reduce the heat lost from the bottom opening 510, and at the same time, can reduce the size of the insulation box 500 in the first direction, thereby reducing the weight of the insulation box 500 and reducing the workload of the translation device 600. In addition, the translation device 600 is provided with a limit block for the auxiliary kiln car 220 to limit the movement distance of the auxiliary kiln car 220 in the first direction, so as to avoid the kiln car 210 from colliding with the rear side wall of the insulation box 500.
[0057] The third driving component is configured to drive the auxiliary kiln car 220 to move toward the cavity, so as to push the kiln car 210 to move into the second kiln body 420. Figure 1 and Figure 3 As shown, the third driving component is fixedly arranged, and is located outside the translation device 600 , for example, the third driving component is installed on the ground, and is located on a side of the auxiliary kiln car 220 away from the heat preservation box 500 along the first direction.
[0058] It is understandable that the trolley mechanism adopts such a structural setting, which can reduce the load-bearing capacity of the translation device 600, and can reduce the floor space and overall weight of the translation device 600, thereby reducing the working performance requirements of the first driving component; at the same time, the auxiliary kiln car 220 is exerted with force through the third driving component, and the auxiliary kiln car 220 is used to push the kiln car 210 in the insulation box 500, so that the kiln car 210 in the insulation box 500 is easier to be pushed, avoiding excessive concentration of force on the kiln car 210, which increases the difficulty of pushing, and can also avoid the push rod of the third driving component from bending and breaking due to directly pushing the heavy kiln car 210, thereby reducing the maintenance frequency and cost of the trolley mechanism. Furthermore, when the kiln car 210 is transferred into the heat preservation box 500, the kiln car 210 can exert a thrust on the auxiliary kiln car 220, causing the auxiliary kiln car 220 to move backward into position. At this time, the auxiliary kiln car 220 can be used to ensure that the kiln car 210 moves into position in the heat preservation box 500, thereby preventing the kiln car 210 from hitting the rear side wall of the heat preservation box 500.
[0059] The third driving component is disposed opposite to the second kiln body 420 along the first direction, and the number of the third driving component is not limited to one.
[0060] The third driving component has a push rod, which is configured to be retractable along the first direction, and can exert a thrust on the auxiliary kiln car 220, so that the third driving component drives the auxiliary kiln car 220 to move toward the cavity, so that the auxiliary kiln car 220 can push the kiln car 210 located in the cavity. The third driving component can be, but is not limited to, the second hydraulic propulsion machine 700.
[0061] Of course, it is not excluded that in other embodiments, the third driving component is disposed on the translation device 600 . In this case, the third driving component can move along with the translation device 600 along the second direction.
[0062] In some embodiments, Figure 3 , Figure 4 and Figure 6As shown, the high-efficiency and energy-saving rotary tunnel kiln also includes an auxiliary wall 830. The first kiln body 410 and the second kiln body 420 are arranged at a certain interval along the second direction, one end of the auxiliary wall 830 along the second direction is fixedly connected to the outer side surface of the first kiln body 410, and the other end of the auxiliary wall 830 along the second direction is fixedly connected to the outer side surface of the second kiln body 420, and the rear side surface of the auxiliary wall 830 is flush with the same side end surface of the first kiln body 410 and the second kiln body 420 along the first direction. Therefore, the gap between the front side surface of the insulation box 500 and the rear end surface of the first kiln body 410, the gap between the front side surface of the insulation box 500 and the rear side surface of the auxiliary wall 830, and the gap between the front side surface of the insulation box 500 and the rear end surface of the second kiln body 420 are all the same, and the auxiliary wall 830 can be made of insulation materials such as insulation bricks.
[0063] It is understandable that when the insulation box 500 moves along the second direction between the first kiln body 410 and the second kiln body 420, the auxiliary wall 830 can cooperate with the first kiln body 410 and the second kiln body 420 to enclose the cavity opening of the insulation box 500, thereby avoiding a large amount of heat energy in the insulation box 500 being dissipated outward through the cavity opening, resulting in large temperature fluctuations in the insulation box 500, causing a large temperature difference between the insulation box 500, the first kiln body 410 and the second kiln body 420, and affecting the quality of the foam ceramic product.
[0064] Further, such as Figure 4 and Figure 6 As shown, a detachable connection mechanism is provided between the heat preservation box 500 and the heat preservation wall. The detachable connection mechanism includes a hook 911, a connecting shaft 920 and a fourth driving component. The hook 911 can be snap-connected or released with the connecting shaft 920. The length of the connecting shaft 920 extends along the first direction, and the connecting shaft 920 is a round shaft. The hook 911 is hingedly mounted. Moreover, one of the hook 911 and the connecting shaft 920 is arranged on the top of the heat preservation box 500, and the other is arranged on the top of the heat preservation wall. The fourth driving component is configured to drive the hook 911 to swing around its hinge axis so that the hook 911 can be snap-connected to the connecting shaft 920 or detached from the connecting shaft 920.
[0065] It is understandable that the fourth driving component can be a device such as a cylinder, an electric cylinder, a hydraulic cylinder, a rotary cylinder or a motor that can drive the hook 911 to rotate. When the hook 911 is set on the top of the insulation box 500 and the connecting shaft 920 is set on the top of the insulation wall, the fourth driving component is set on the top of the insulation box 500; if the fourth driving component is a cylinder, one end of the cylinder is hinged to the insulation box 500, and the other end is hinged to the hook 911. When the hook 911 is set on the top of the insulation wall and the connecting shaft 920 is set on the top of the insulation box 500, the fourth driving component is set on the top of the insulation wall.
[0066] When the insulation box 500 is docked with the first kiln body 410 and the kiln car 210 is transferred to the insulation box 500, the insulation box 500 will move toward the second kiln body 420. At this time, the second insulation wall 820 blocks the opening structure of the second kiln body 420. The corresponding fourth driving component will drive the hook 911 to swing and can hook the connecting shaft 920 on the first insulation wall 810, prompting the insulation box 500 and the first insulation wall 810 to establish a fixed connection relationship, so that the insulation box 500 and the first insulation wall 810 can move toward the second kiln body 420 under the driving action of the translation device 600. During this movement, the insulation box 500 can push the second insulation wall 820 to move.
[0067] Moreover, after the insulation box 500 moves a certain distance, the corresponding fourth driving component can be used to drive the hook 911 to rotate and engage with the connecting shaft 920 on the second insulation wall 820, so that a fixed connection relationship is established between the insulation box 500 and the second insulation wall 820, thereby avoiding the second insulation wall 820 being pushed too far when the insulation box 500 is docked with the second kiln body 420, resulting in the insulation box 500 being unable to connect with the second insulation wall 820 through the detachable connecting mechanism.
[0068] When the first insulation wall 810 moves into position and covers the opening structure of the first kiln body 410, the corresponding fourth driving component will drive the hook 911 to swing, causing the hook 911 to disengage from the connecting shaft 920 on the first insulation wall 810, so that the insulation box 500 and the first insulation wall 810 are separated, thereby reducing the workload of the translation device 600 and saving energy.
[0069] When the insulation box 500 is moved into place and docked with the second kiln body 420, the insulation box 500 and the second insulation wall 820 maintain a good connection. At the same time, the first insulation wall 810 is separated from the insulation box 500 and blocks the opening structure of the first kiln body 410 to prevent a large amount of high-temperature gas in the first kiln body 410 from leaking out.
[0070] Similarly, when the insulation box 500 moves from the second kiln body 420 to the first kiln body 410, the conditions between the insulation box 500 and the first insulation wall 810 and between the insulation box 500 and the second insulation wall 820 are opposite to the above conditions, which will not be described in detail here.
[0071] Moreover, the size of the first insulation wall 810 and the second insulation wall 820 in the second direction can be set according to the opening structure of the first kiln body 410 and the opening structure of the second kiln body 420. In the case of adding a detachable connection mechanism, the size of the first insulation wall 810 and the second insulation wall 820 in the second direction can be reduced, thereby reducing the manufacturing cost of the energy-efficient rotary tunnel kiln.
[0072] In this embodiment, if Figure 4 and Figure 6 As shown, the structure of the fourth driving component includes a guide wheel 912 and a guide block 930. Among them, the top of the heat preservation box 500 is provided with hooks 911 on both sides along the second direction, and the hooks 911 are arranged near the opening of the cavity. One end of the hook 911 is hinged to the heat preservation box 500 through a hinge shaft, and one end of the hook 911 extends downward to form a connecting arm, and the connecting arm and the hook 911 can be integrally formed.
[0073] The guide wheel 912 is rotatably disposed on the connecting arm, and the guide wheel 912 can rotate relative to the hook 911, and the rotation axis of the guide wheel 912 extends along the first direction. The total gravity of the guide wheel 912 and the connecting arm is greater than the gravity of the hook 911, so that when not affected by external forces, the connecting arm is vertically arranged, the hook 911 is tilted upward, and the bayonet of the hook 911 is downwardly arranged. In addition, a guide surface for guiding the connecting shaft 920 is arranged at one end of the hook 911 away from the connecting arm, and the guide surface is tilted from top to bottom toward the bayonet of the hook 911. Moreover, the hook 911 is configured to swing downward under the gravity of the connecting arm and the guide wheel 912, and be clamped to the connecting shaft 920.
[0074] It can be understood that when the insulation box 500 contacts and pushes one of the insulation walls, the guide surface of the hook 911 will contact the connecting shaft 920 on the insulation wall and produce a guiding effect, causing the hook 911 to swing upward under the force of the connecting shaft 920 until the connecting shaft 920 moves along the guide surface to the hook of the hook 911. The hook 911 will then swing downward by itself due to the gravity of the connecting arm and the guide wheel 912, causing the hook 911 to hook the connecting shaft 920.
[0075] Guide blocks 930 are provided on both sides of the top of the auxiliary wall 830 along the second direction, and the guide blocks 930 are fixed to the surface of the auxiliary wall 830 close to the heat preservation box 500 along the first direction. The ends of the two guide blocks 930 that are away from each other are provided with guide lifting surfaces; specifically, the guide block 930 located on the left side of the auxiliary wall 830 has a guide lifting surface, the guide lifting surface is located on the left side of the guide block 930, and the guide lifting surface is inclined from top to bottom to the left; the guide block 930 located on the right side of the auxiliary wall 830 has a guide lifting surface, the guide lifting surface is located on the right side of the guide block 930, and the guide lifting surface is inclined from top to bottom to the right.
[0076] In this embodiment, if Figure 4 and Figure 6 As shown, the guide block 930 is in the shape of an isosceles trapezoid.
[0077] Moreover, the guide block 930 is configured to contact with the guide wheel 912, and drive the guide wheel 912 to drive the hook 911 to swing upward, so that the hook 911 is separated from the connecting shaft 920. It can be understood that when one of the insulation walls moves into place under the driving action of the insulation box 500 and blocks the corresponding opening structure, the corresponding guide wheel 912 on the insulation box 500 will contact the guide lifting surface of the corresponding guide block 930, and the guide wheel 912 will roll along the guide lifting surface, prompting the guide wheel 912 to drive the hook 911 to swing upward, so that the hook 911 is separated from the corresponding connecting shaft 920, thereby separating the insulation wall from the insulation box 500.
[0078] The installation positions of the guide block 930 and the hook 911 can be set according to actual conditions, as long as the condition that the hook 911 can be separated from the connecting shaft 920 is met when the insulation wall just covers the corresponding opening structure.
[0079] The fourth driving component adopts the above-mentioned structure, and can automatically drive the hook 911 to separate from the connecting shaft 920, without using energy, saving energy and being environmentally friendly, and having low cost.
[0080] like Figures 1 to 6 As shown, the use process of the high-efficiency and energy-saving rotary tunnel kiln provided by the embodiment of the present invention is as follows: the first hydraulic pusher 100 located at the kiln head drives the push head to move linearly through the hydraulic cylinder, so that the push head can steadily push the kiln car 210 with the foam ceramic blank 300, so that the kiln cars 210 move backward one by one in the first kiln body 410. At this time, any two adjacent kiln cars 210 are close to each other, such as Figure 1 and Figure 2 When one of the kiln cars 210 moves to the opening structure of the first kiln body 410 , the heat preservation box 500 just docks with the first kiln body 410 , so that the kiln cavity of the first kiln body 410 is connected with the cavity of the heat preservation box 500 .
[0081] Next, since the first hydraulic propulsion machine 100 is still working, the kiln car 210 is pushed toward the heat preservation box 500 by the kiln car 210 in front of it. At this time, the first driving component runs and drives the translation seat 650 to drive the hook 660 and the second driving component to move forward. When the hook 660 moves into place, the hook 660 is located below the kiln car 210. The second driving component will start and drive the hook 660 to rotate, so that the hook 660 can have a certain clamping effect with the kiln car 210.
[0082] Then, the first driving component is started again and drives the translation seat 650 to move backward, so that the hook 660 can be dragged into the cavity of the kiln car 210 to the heat preservation box 500, so that the kiln car 210 is pulled away from the kiln car 210 in front of it by a certain distance, so that the heat preservation box 500 will not be hindered by the kiln car 210 during the movement in the second direction.
[0083] Subsequently, the translation device 600 operates and drives the heat preservation box 500, the kiln car 210 and the auxiliary kiln car 220 to move linearly along the second direction until the heat preservation box 500 and the second kiln body 420 can be docked. During the movement of the heat preservation box 500, since the heat preservation box 500 is connected to the first heat preservation wall 810 through a detachable connection mechanism, the first heat preservation wall 810 can move synchronously with the heat preservation box 500, such as Figure 6 When the guide wheel 912 on the right side of the heat preservation box 500 passes the guide block 930 on the right side of the auxiliary wall 830, the guide wheel 912 drives the hook 911 to swing upward under the guidance of the guide block 930, so that the hook 911 is separated from the connecting shaft 920 on the first heat preservation wall 810, so that the first heat preservation wall 810 can stay at the opening structure of the first kiln body 410, and the opening structure of the first kiln body 410 is sealed.
[0084] After the first insulation wall 810 is separated from the insulation box 500, the insulation box 500 continues to move under the driving action of the translation device 600, and is able to push the second insulation wall 820 located at the opening structure of the second kiln body 420. At this time, the hook 911 located on the left side of the insulation box 500 swings upward due to its guide surface contacting the connecting shaft 920 on the second insulation wall 820, and automatically swings downward under the action of the gravity of the guide wheel 912 and the connecting arm, so that the hook 911 hooks the connecting shaft 920 on the second insulation wall 820, as shown in FIG. Figure 4 shown.
[0085] When the heat preservation box 500 just docks with the second kiln body 420, the translation device 600 stops running, and the second heat preservation wall 820 is pushed away from the opening structure of the second kiln body 420. At this time, the second hydraulic propulsion machine 700 is started, which can push the auxiliary kiln car 220, so that the auxiliary kiln car 220 can push the kiln car 210 in the cavity and push the kiln car 210 into the second kiln body 420. At the same time, the hook 660 rotates in the opposite direction under the driving action of the second driving component, so that the hook 660 is in a horizontal state, thereby releasing the clamping effect between the hook 660 and the kiln car 210, so that the hook 660 will not hinder the kiln car 210 from moving along the first direction to the second kiln body 420.
[0086] When the kiln car 210 is transferred from the heat preservation box 500 to the second kiln body 420, the hydraulic cylinder of the second hydraulic propulsion machine 700 is retracted, and the hook 660 is rotated under the driving action of the second driving component, so that the hook 660 is in a tilted state and can be engaged with the auxiliary kiln car 220. Then, the first driving component is operated, so that the translation seat 650 can drive the hook 660 to move backward, so that the hook 660 can drag the auxiliary kiln car 220 to move backward, so that the auxiliary kiln car 220 and the kiln car 210 in the second kiln body 420 are pulled away by a certain distance.
[0087] Then, the translation device 600 runs in the reverse direction, and the translation device 600 can drive the heat preservation box 500, the auxiliary kiln car 220 and the second heat preservation wall 820 to move together in the second direction until the heat preservation box 500 is docked with the first kiln body 410. During the movement, when the guide wheel 912 located on the left side of the heat preservation box 500 passes the guide block 930 located on the left side of the auxiliary wall 830, the guide wheel 912 drives the hook 911 to swing upward under the guidance of the guide block 930, so that the hook 911 is separated from the connecting shaft 920 on the second heat preservation wall 820, so that the second heat preservation wall 820 stays at the opening structure of the second kiln body 420, and the opening structure of the second kiln body 420 is sealed.
[0088] When the second insulation wall 820 is separated from the insulation box 500, the translation device 600 will drive the insulation box 500 to continue to move, so that the insulation box 500 can contact and push the first insulation wall 810 located at the opening structure of the first kiln body 410. At this time, the hook 911 located on the right side of the insulation box 500 contacts the connecting shaft 920 on the first insulation wall 810 and swings upward, and due to the gravity of the guide wheel 912 and the connecting arm, it swings in the opposite direction by itself, so that the hook 911 can hook the connecting shaft 920 on the first insulation wall 810.
[0089] When the insulation box 500 is just connected to the first kiln body 410, the first insulation wall 810 is pushed away from the opening structure of the first kiln body 410, and the insulation box 500 seals the opening structure of the first kiln body 410 and waits for the next kiln car 210 to enter.
[0090] In the energy-efficient rotary tunnel kiln provided by the embodiment of the present invention, when the kiln car 210 carries the foam ceramic body 300 and moves to the opening structure of the first kiln body 410 along the extension direction of the first kiln body 410, the heat preservation box 500 is driven by the translation device 600 to move to the opening structure of the first kiln body 410, so that the opening of the cavity is connected to the inside of the first kiln body 410, then, the kiln car 210 located at the opening structure can be dragged from the first kiln body 410 to the cavity through the action of the push-pull device; then, the translation device 600 is operated to drive the heat preservation box 500 and its The kiln car 210 on the kiln body 420 moves along the second direction to the opening structure of the second kiln body 420, so that the opening of the cavity is connected with the interior of the second kiln body 420. Then, with the help of the push-pull device, the kiln car 210 located in the cavity is pushed from the heat preservation box 500 to the second kiln body 420. Such a design can make the tunnel kiln body have a two-stage structure, which not only ensures that the foam ceramic blank 300 on the kiln car 210 can complete the firing work, but also can reduce the land occupation requirement of the factory building, improve the space utilization rate of the factory building, and at the same time, can shorten the turnover distance of the foam ceramic product out of the kiln and improve production efficiency.
[0091] Moreover, during the operation of the translation device 600, the insulation wall can move along with the insulation box 500. When the insulation box 500 is docked with one of the opening structures to realize the transfer of the kiln car 210, the insulation box 500 can cover the opening structure. At the same time, one of the insulation walls can cover the other opening structure, which can reduce the heat dissipated to the outside by the first kiln body 410 and the second kiln body 420, thereby achieving the purpose of energy saving and environmental protection.
