Description

Technical Field

[0001] The present invention relates to the technical field of kilns, and particularly relates to a mobile energy-saving kiln. Background Art

[0002] At present, most of the common kilns on the market adopt the working mode of fixing the kiln body and running the kiln car. The firing and transportation of products are realized by moving the kiln car. When facing some products with large volume or large weight, it is very difficult to ensure the stability of kiln tools or products during the process of the kiln car entering and leaving the kiln body, and there are some operation safety risks. At the same time, in addition to the need for its own track for the kiln car to run, the traditional kiln also requires a running vehicle, auxiliary tracks, etc., which occupy a large area of equipment and waste working space. Summary of the Invention

[0003] Aiming at the defects existing in the above-mentioned prior art, the technical problems solved by the present invention are:

[0004] How to ensure the safety and stability of products with large volume or large mass during the operation process, and how to save the occupied space of the kiln.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] A mobile energy-saving kiln, including a kiln body and a kiln bed. Guide rails are provided on both sides of the kiln bed. A plurality of kiln body placement areas are provided between the guide rails. Two kiln doors are provided on the kiln body. A moving mechanism is provided at the bottom end of the kiln body. The moving mechanism is controlled by a hydraulic system to lift or move linearly. When the hydraulic system drives the moving mechanism to move linearly, the moving mechanism drives the kiln body to move on the guide rails. When the hydraulic system drives the moving mechanism to move up and down, the kiln body and the kiln body placement area form a sealed product firing chamber.

[0007] Further, a kiln side pipe is provided on the kiln body. A smoke exhaust fan is provided on the kiln side pipe. The smoke exhaust fan is connected with a smoke exhaust interface. A kiln wall is provided on one side of the kiln body. A smoke exhaust branch pipe is provided on the kiln wall. When the kiln body moves to the kiln body placement area, the smoke exhaust interface is docked with the smoke exhaust branch pipe. There are a plurality of the smoke exhaust branch pipes, and the plurality of smoke exhaust branch pipes converge into a smoke exhaust main pipe.

[0008] Further, a gas pipeline and a combustion-supporting pipeline are also provided on the kiln body. The kiln side pipe, the smoke exhaust branch pipe, the smoke exhaust main pipe, the gas pipeline and the combustion-supporting pipeline form a kiln combustion system.

[0009] Further, the kiln wall and the kiln bed are connected as a whole.

[0010] Further setting: A plurality of regenerative burners are provided on the side wall of the kiln body. The regenerative burner includes a burner brick, a regenerator box, and a smoke exhaust port. The power of the regenerative burner increases successively from bottom to top.

[0011] Further setting: The moving mechanism includes a hydraulic cylinder. A kiln shaft is provided at the bottom end of the hydraulic cylinder. A wheel seat and wheels are provided at the bottom end of the kiln shaft. The wheels are connected to the side wall of the wheel seat through a wheel shaft. A driven gear is further connected to the wheel shaft. A motor and a main gear are further provided on the wheel seat. A chain is provided between the main gear and the driven gear.

[0012] Further setting: A wheel mounting plate is fixed on the hydraulic cylinder. The wheel mounting plate is connected to the kiln body. A protective sleeve is sleeved on the kiln shaft. The protective sleeve is fixedly connected to the wheel mounting plate.

[0014] Further setting: A burner controller is provided at the burner.

[0015] Further setting: A fence is provided at the top end of the kiln body. A corridor frame is provided on the fence. A ladder is connected to the corridor frame.

[0016] Further setting: A combustion-supporting fan is provided on the combustion-supporting pipeline.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] (1) By adopting the working mode of the kiln body running and the products being fixed in the kiln placement area, the loss caused by the movement of products with heavier mass or larger volume is greatly reduced, the stability and yield of the products are ensured, the damage of kiln furniture, etc. is avoided, and the safety risk of operation is reduced.

[0019] (2) There is no need to adopt auxiliary tools such as kiln cars, transfer cars, and traction tracks. Only one guide rail is designed to realize the operation of the kiln furnace, which not only saves costs, but also greatly reduces the occupied area of the entire kiln furnace. Compared with the traditional kiln furnace, the present invention only needs 1 / 2 of the occupied area to achieve the same production capacity.

[0020] (3) By setting a plurality of kiln placement areas, after the present invention completes the firing of one kiln placement area, it can immediately move to the next kiln placement area to continue working. Repeating like this, it has high safety, convenient operation, and effectively improves the production efficiency of the kiln furnace.

[0021] (4) Adopt regenerative combustion technology, which can achieve a thermal efficiency of about 60-70% in the field of high-temperature kilns. Set regenerative burners, integrating burner bricks, regenerative boxes and exhaust ports, with a compact structure, small volume and space saving. It is not only convenient for the movement of the kiln body, but also saves more than 30% energy compared with traditional kilns.

[0022] (5) Cleverly design the moving mechanism to make it perfectly match with the guide rails and the kiln body placement area, achieving the purpose of lifting and linear movement of the kiln body. BRIEF DESCRIPTION OF THE DRAWINGS

There are 2 kiln doors 5 on the kiln body 1, and a moving mechanism 6 is provided at the bottom end of the kiln body 1. The moving mechanism 6 is controlled by a hydraulic system 7 to lift or move linearly. When the hydraulic system 7 drives the moving mechanism 6 to move linearly, the moving mechanism 6 drives the kiln body 1 to move on the guide rails 3. When the hydraulic system 7 drives the moving mechanism 6 to move up and down, the kiln body 1 and the kiln body placement area 4 form a sealed product firing chamber.

[0032] A kiln side pipeline 8 is provided on the kiln body 1. A smoke exhaust fan 9 is provided on the kiln side pipeline 8, and a smoke exhaust interface 10 is connected to the smoke exhaust fan 9. A kiln wall 11 is provided on one side of the kiln body 1. The kiln wall 11 is integrally connected to the kiln bed 2. A smoke exhaust branch pipe 12 is provided on the kiln wall 11. When the kiln body 1 moves to the kiln body placement area 4, the smoke exhaust interface 10 is docked with the smoke exhaust branch pipe 12. There are multiple smoke exhaust branch pipes 12, and the multiple smoke exhaust branch pipes 12 converge into a smoke exhaust main pipe 13. The number of the exhaust branch pipes 12 is the same as the number of the kiln body placement areas 4, ensuring that there is a corresponding smoke exhaust branch pipe 12 when the kiln body 1 is fired in each kiln body placement area 4. A gas pipeline 14 and a combustion-supporting pipeline 15 are also provided on the kiln body 1. The above-mentioned kiln side pipeline 8, smoke exhaust branch pipe 12, gas pipeline 14 and combustion-supporting pipeline 15 constitute the kiln combustion system. In addition, an electrical system and detection instruments are also provided on the kiln body 1. The combustion system, electrical system and detection instruments all move together with the kiln body 1.

[0033] A combustion-supporting fan 21 is provided on the combustion-supporting pipeline 15.

[0034] A plurality of regenerative burners 16 are provided on the side wall of the kiln body 1, and the power of the regenerative burners 16 increases sequentially from bottom to top. As Figure 5 shown, the regenerative burner 16 includes a burner brick 1601, a regenerative box 1602 and a smoke exhaust port 1603. The burner brick 1601 is arranged inside the kiln body 1, and the regenerative box 1602 and the smoke exhaust port 1603 are arranged outside the kiln body 1. The smoke exhaust port 1603 is connected to the kiln side pipeline 8, and a burner controller 17 is provided at the burner 16.

[0035] A fence 18 is provided at the top end of the kiln body 1. A corridor frame 19 is provided on the fence 18, and a ladder 20 is connected to the corridor frame 19.

[0036] Embodiment 1

[0037] As Figure 4 shown, the kiln body placement area 4 is set to 2.

[0038] Figure 6Among them, the moving mechanism 6 includes a hydraulic cylinder 601. At the bottom end of the hydraulic cylinder 601, there is a kiln jacking shaft 602. At the bottom end of the kiln jacking shaft 602, there are a wheel seat 603 and a wheel 604. The wheel 604 is connected to the side wall of the wheel seat 603 through a wheel axle 605. A driven sprocket 606 is also provided on the wheel axle 605. A motor 607 and a main sprocket 608 are provided on the wheel seat 603. A chain 609 is provided between the main sprocket 608 and the driven sprocket 606. At the same time, a wheel mounting plate 610 is fixed on the hydraulic cylinder 601. The wheel mounting plate 610 is connected to the kiln body 1. A protective sleeve 611 is sleeved on the kiln jacking shaft 602. The protective sleeve 611 is fixedly connected to the wheel mounting plate 610.

[0039] Working principle:

[0040] Place the product in the kiln body placement area 4. The hydraulic cylinder 601 makes an extending action to jack up the wheel mounting plate 610. Since the wheel mounting plate 610 is installed together with the kiln body 1, the entire kiln body 1 starts to rise. When the kiln body 1 rises in place, the motor 607 makes a rotating action, and drives the wheel 604 to rotate on the guide rail 3 through the chain 609 and the sprocket components. The entire kiln body 1 moves forward. When it moves to the kiln body placement area 4, the motor 607 stops rotating. The hydraulic cylinder 601 makes a retracting action. The bottom end of the kiln body 1 and the kiln body placement area 4 form a sealed product firing chamber. When the kiln furnace is firing in one kiln body placement area 4, the user can load and unload in another kiln body placement area 4. After the kiln furnace finishes firing, open the two kiln doors 5, and it can immediately move to the next kiln body placement area 4 to continue firing. Repeat this process to achieve a very high working efficiency.

[0041] This embodiment does not need to adopt auxiliary tools such as kiln cars, transfer cars, and traction tracks, which not only saves costs but also reduces the occupied area of the entire kiln furnace. At the same time, the regenerative burner 16 with the burner brick 1601 and the regenerator box 1602 integrated further improves the space utilization rate.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
