Description

Technical Field

[0001] This utility model relates to the field of kiln firing technology, and in particular to a liftable electric-electric kiln. Background Technology

[0002] An electric-electric kiln is a dual-purpose kiln that can fire ceramics using both electric heating and open flame methods.

[0003] A search revealed a Chinese patent publication number, CN219178298U, which discloses a liftable electric-electric kiln. The kiln includes a furnace body, a support frame, a lifting base, a lifting drive, a gas nozzle, and an electric heating rod. The bottom of the furnace body has several insertion holes. The bottom of each insertion hole penetrates the furnace body, and a flip-top plate is provided at the top. The gas nozzle is vertically mounted on the lifting base and corresponds to each insertion hole. The lifting base moves the gas nozzle upwards, opening the flip-top plate and extending it into the firing chamber, or downwards and exiting the firing chamber. The electric heating rod is connected to a power source and installed inside the firing chamber. This invention, by providing a liftable and movable gas nozzle, avoids keeping the gas nozzle constantly heated, thus reducing wear and tear on the gas components.

[0004] Although the aforementioned patent allows for the lifting and moving of the gas-fired spray gun to fire products, the aforementioned liftable electric-electric kiln still has the following problems: Since the device fires products by lifting the spray gun, after firing, the spray gun is removed from the furnace and exposed to the external environment. Although the existing device can complete the basic combustion and heating functions, the spray gun is still exposed when the machine is stopped. In the industrial production environment, there is a lot of dust, ash, and oil around the kiln. The spray gun lacks closed protection when it is idle, and the nozzle area is easily covered or blocked by debris. It may even cause particles to fall in, leading to unstable secondary ignition. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a liftable electric kiln that protects the spray gun in standby mode.

[0006] This utility model is achieved through the following technical solution: a liftable electric-electric kiln, including a kiln body, a firing chamber inside the kiln body, a support base fixedly connected to the bottom of the kiln body, grooves on both sides of the support base, a bracket fixedly connected to the bottom of the support base, rollers at the bottom of the bracket, a protective box fixedly connected between the support base and the bracket, the interior of the protective box communicating with the interior of the kiln body, a support plate fixedly connected to the inner wall of the protective box, the support plate having a hollow structure, and a power adjustment device installed inside the support plate.

[0007] Furthermore, the power adjustment device includes a bidirectional threaded rod, which is rotatably connected to the inside of the support plate. The surface of the bidirectional threaded rod has two opposite threads, and a first bevel gear is fixedly connected to the surface of the bidirectional threaded rod. The first bevel gear is rotatably connected to the inside of the support plate through the bidirectional threaded rod.

[0008] Furthermore, the surface threaded connection of the bidirectional threaded rod has two protective plates, which are located on two opposite threads respectively.

[0009] Furthermore, both sides of the protective box are provided with movable grooves that communicate with their interiors. The interior of the movable grooves communicates with the interior of the recesses, and the protective plate is slidably connected to the interior of the movable grooves.

[0010] Furthermore, a motor is fixedly connected to the lower surface inside the protective box, and a threaded rod is fixedly connected to the output end of the motor. The top of the threaded rod rotates through the support plate and extends into it. A second bevel gear that meshes with the first bevel gear is fixedly connected to the top of the threaded rod.

[0011] Furthermore, a movable frame is threadedly connected to the surface of the threaded rod, a connecting bracket is fixedly connected to the inner wall of the movable frame, the connecting bracket has a cross-shaped cross section, and a spray gun is fixedly connected to the inner wall of the movable frame.

[0012] Furthermore, a limiting rod is fixedly connected to the lower surface inside the protective box, and the interior of the movable frame is slidably connected to the surface of the limiting rod.

[0013] Furthermore, a movable door is provided on one side of the protective box.

[0014] The beneficial effects of this utility model are as follows: This liftable electric-electric kiln can completely seal the top of the protective box by opening and closing two protective plates, forming a relatively sealed protective chamber. When the spray gun is not in use, it can prevent external dust, ash, and oil from entering the protective box. High-temperature ash, airborne particles, and material debris may accumulate on the spray gun nozzle, causing nozzle blockage, ignition failure, or even abnormal combustion.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Example 1 like Figures 1-4 As shown, a liftable electric-electric kiln includes a kiln body 1, which is an existing structure and will not be described in detail. The kiln body 1 has a firing chamber inside for firing and processing products. A support base 2 is fixedly connected to the bottom of the kiln body 1 to support the kiln body 1. Grooves 16 are provided on both sides of the support base 2. A bracket 3 is fixedly connected to the bottom of the support base 2. Rollers are provided at the bottom of the bracket 3 for moving the device. A protective box 4 is fixedly connected between the support base 2 and the bracket 3. The interior of the protective box 4 is connected to the interior of the kiln body 1. The protective box 4 can protect and transmit the internal parts. A support plate 10 is fixedly connected to the inner wall of the protective box 4. The interior of the support plate 10 is a hollow structure. A power adjustment device is provided inside the support plate 10.

[0020] The power adjustment device includes a bidirectional threaded rod 13, which is rotatably connected to the inside of the support plate 10. The surface of the bidirectional threaded rod 13 has two opposite threads. A first bevel gear 11 is fixedly connected to the surface of the bidirectional threaded rod 13. The first bevel gear 11 is rotatably connected to the inside of the support plate 10 through the bidirectional threaded rod 13. By rotating the bidirectional threaded rod 13, the bidirectional threaded rod 13 can drive the first bevel gear 11 to rotate. The surface of the bidirectional threaded rod 13 is threaded with two symmetrical protective plates 15, which are located on the two opposite threads respectively.

[0021] Both sides of the protective box 4 are provided with movable grooves 14 that communicate with the interior of the box. The interior of the movable grooves 14 communicates with the interior of the grooves 16. The protective plate 15 is slidably connected to the interior of the movable grooves 14. The movable grooves 14 can limit the movement of the protective plate 15, making it slide more smoothly and stably and less prone to tilting.

[0022] A motor 7 is fixedly connected to the lower surface inside the protective box 4. A power supply, wiring, controller, and microcomputer structure are installed to match the motor 7. The motor 7 is a reversible motor. Since the motor 7 is not a major structure, it will not be described in detail. A threaded rod 8 is fixedly connected to the output end of the motor 7. The top of the threaded rod 8 rotates through the support plate 10 and extends into it. A second bevel gear 12, which meshes with the first bevel gear 11, is fixedly connected to the top of the threaded rod 8. The operator starts the motor 7 via an external control device, and the output end of the motor 7 drives the threaded rod 8 to rotate in both directions. The output end of the threaded rod 8 drives the second bevel gear 12 to rotate. The second bevel gear 12 drives the bidirectional threaded rod 13 to rotate in both directions through meshing with the first bevel gear 11. The bidirectional threaded rod 13 can drive the two protective plates 15 to move relative to each other and in opposite directions. The surface of the threaded rod 8 is threadedly connected to a movable frame 5. The inner wall of the movable frame 5 is fixedly connected to a connecting frame 9 for supporting the movable frame 5. The cross section of the connecting frame 9 is "cross-shaped". Multiple spray guns 18 are fixedly connected to the inner wall of the movable frame 5. The product can be fired by starting the spray guns 18.

[0023] Multiple limiting rods 6 are fixedly connected to the lower surface inside the protective box 4. The inside of the moving frame 5 is slidably connected to the surface of the limiting rods 6. The limiting rods 6 can limit the moving frame 5, making it slide smoothly and stably. While the threaded rod 18 drives the bidirectional threaded rod 13 to rotate, the thread on its surface drives the moving frame 5 to move up and down synchronously under the limitation of the limiting rods 6. The moving frame 5 drives the spray gun 18 to slide up and down. The spray gun 18 can be moved into the kiln body 1 to fire the product, or it can be retracted into the protective box 4 for storage after firing. The spray gun 18 is a certain distance away from the inner wall of the protective box 4, so that the opening and closing of the protective plate 15 will not affect the raising and lowering of the spray gun 18.

[0024] By opening and closing the two protective plates 15, the top of the protective box 4 can be completely sealed, forming a relatively sealed protective chamber. This can prevent external dust, ash, and oil from entering the interior of the protective box 4. High-temperature ash, airborne particles, and material debris may accumulate on the nozzle of the spray gun 18, causing nozzle blockage, ignition failure, or even abnormal combustion.

[0025] A movable door 17 is provided on one side of the protective box 4. By rotating the movable door 17, the interior of the protective box 4 can be inspected and maintained in a timely manner.

[0026] This embodiment provides a liftable electric-electric kiln. In use, the operator first places the product to be fired inside the kiln body 1. Then, the motor 7 is started via an external control device. The output of the motor 7 drives a threaded rod 8 to rotate in both directions. When the threaded rod 8 rotates, it drives a second bevel gear 12 located at its end to rotate synchronously. The second bevel gear 12 meshes with a first bevel gear 11, causing the first bevel gear 11 to drive a bidirectional threaded rod 13 to rotate in both directions. When the bidirectional threaded rod 13 rotates, its opposing threaded structures simultaneously push... The two protective plates 15 move in opposite directions to achieve synchronous opening and closing of the protective plates 15. When the device enters the firing condition, the protective plates 15 are opened and the two sides separate outward, providing a fully open lifting space for the spray gun 18. At the same time, driven by the rotation of the bidirectional threaded rod 13, the threaded rod 8 connected to its transmission also rotates synchronously. The threaded rod 8 drives the moving frame 5 to move up and down in the vertical direction under the limiting action of the limiting rod 6 through its surface thread. The moving frame 5 drives the spray gun 18 to rise and fall stably, so that the spray gun 18 can rise into the kiln body 1 to heat and fire the placed products. After the spray gun 18 is completely retracted into the protective box 4, the bidirectional threaded rod 13 continues to rotate in the opposite direction. The two protective plates 15 close inward under the action of the threads, sealing the top of the protective box 4, thus forming a protective state for the spray gun 18 and preventing it from being affected by residual heat radiation from the furnace or external dust pollution when it is in standby mode.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
