Description

A type of diesel-electric kiln for firing ceramics Technical Field

[0001] This invention relates to the field of kiln technology, specifically to a diesel-electric kiln for firing ceramics. Background Technology

[0002] Modern electric kilns simply use electricity to fire porcelain and do not have the function of burning wood, which limits the range of kiln transformation in porcelain.

[0003] In addition, when firing ceramics in electric or wood-fired kilns, the kiln door needs to be slightly opened after ignition and during cooling after firing. Slightly opening the kiln door after ignition helps to remove moisture. After removing the moisture, the kiln door should be completely closed for firing. Slightly opening the kiln door during cooling after firing helps to cool down. Currently, electric kilns require manual closing of the slightly opened kiln door during use, which can easily cause burns to workers.

[0004] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a wood-fired electric kiln for firing ceramics, which has the following advantages: the kiln does not require manual closing of the partially opened kiln door, thereby reducing the risk of burns to workers; and the electric kiln can burn wood during the ceramic firing process, increasing the range of kiln transformations.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention provides a diesel-electric kiln for firing ceramics, comprising a kiln body, a first sliding plate, a second sliding plate, and a kiln door hinged to one side of the kiln body for sealing the kiln opening. The first sliding plate is horizontally slidably connected to the bottom end of the kiln body, and the second sliding plate is horizontally slidably connected to the top end of the kiln body. The kiln body is provided with a power component for simultaneously pushing the first and second sliding plates horizontally. The first and second sliding plates move towards or away from the hinge point between the kiln door and the kiln body. The first and second sliding plates are provided with a first pushing component connected to the kiln door. When the first and second sliding plates move horizontally, the first pushing component drives the kiln door to rotate along the hinge point between the kiln door and the kiln body. Heating wires, which are silicon molybdenum wires, are embedded in the inner wall of the kiln body and the kiln door. A wood-fired furnace is provided at the bottom end of the kiln body, and several communicating grooves for communication with the wood-fired furnace are opened at the bottom end of the kiln body. An exhaust pipe is connected to the top end of the kiln body. Attached Figure Description

[0020] A diesel-electric kiln for firing ceramics, as shown in Figures 1, 2, and 9, includes a kiln body 1, a first sliding plate 2, a second sliding plate 3, and a kiln door 4 hinged to one side of the kiln body 1 for sealing the kiln opening. The first sliding plate 2 is horizontally slidably connected to the bottom end of the kiln body 1, and the second sliding plate 3 is horizontally slidably connected to the top end of the kiln body 1. The kiln body 1 is equipped with a power component for simultaneously pushing the first sliding plate 2 and the second sliding plate 3 horizontally. The first sliding plate 2 and the second sliding plate 3 move towards or away from the hinge point between the kiln door 4 and the kiln body 1. The first sliding plate 2 and the second sliding plate 3 are provided with a first pushing member connected to the kiln door 4. When the first sliding plate 2 and the second sliding plate 3 move horizontally, the first pushing member is used to drive the kiln door 4 to rotate along the hinge point between the kiln door 4 and the furnace body 1. Heating wires 31 are embedded on the inner wall of the furnace body 1 and the kiln door 4. The heating wires 31 are silicon molybdenum wires. A wood-fired furnace 32 is provided at the bottom of the furnace body 1. Several communicating grooves 33 that flow through the wood-fired furnace 32 are opened at the bottom of the furnace body 1. A flue pipe 37 is connected to the top of the furnace body 1.

[0021] As shown in Figures 1, 2, and 9, when firing ceramics, the ceramics are placed inside the furnace body 1, and then the kiln door 4 is pushed to rotate along the hinge point between the kiln door 4 and the furnace body 1 to close the kiln door 4. During the process of closing the kiln door 4, the kiln door 4 approaches the first pusher. As the kiln door 4 rotates, the kiln door 4 contacts the first pusher and automatically connects. At this time, there is a gap between the kiln door 4 and the furnace body 1 for the drainage of moisture inside the furnace body 1. At the same time, the position of the kiln door 4 can be restricted by the first pusher.

[0022] Then, when it is necessary to completely close the kiln door 4, the power component can simultaneously push the first sliding plate 2 and the second sliding plate 3 to move horizontally away from the hinge point between the kiln door 4 and the furnace body 1. At this time, the first pushing component on the first sliding plate 2 and the second sliding plate 3 can drive the kiln door 4 to continue to rotate along the hinge point between the kiln door 4 and the furnace body 1, so that the kiln door 4 is completely closed. There is no need to manually close the slightly open kiln door 4 completely, which solves the problem that workers are easily burned.

[0023] The firewood in the firewood combustion furnace 32 is ignited by the temperature inside the furnace body 1. At this time, the flue gas from the firewood combustion enters the furnace body 1 through each connecting groove 33 to carry out kiln transformation, that is, the flue gas affects the color of the ceramic surface and increases the range of kiln transformation.

[0024] When the ceramics in the furnace body 1 are fired and cooled down, the power component simultaneously pushes the first sliding plate 2 and the second sliding plate 3 horizontally close to the hinge point between the kiln door 4 and the furnace body 1, so that the first pushing component drives the kiln door 4 to rotate along the hinge point between the kiln door 4 and the furnace body 1, opening the kiln door 4 slightly to dissipate heat. After heat dissipation is completed, the kiln door 4 is fully opened, at which point the first pushing component and the kiln door 4 automatically disconnect.

[0025] As shown in Figures 1 and 2, the power unit includes an electric cylinder 5 located at the bottom of the furnace body 1 for pushing the first sliding plate 2 to move horizontally. The first sliding plate 2 and the second sliding plate 3 are connected on one side by a U-shaped connecting plate 6. The connecting plate 6 is located on the outside of the furnace body 1, and the vertical edge of the connecting plate 6 is close to the hinge point between the kiln door 4 and the furnace body 1. The purpose of this arrangement is that when it is necessary to push the first sliding plate 2 and the second sliding plate 3 to move horizontally at the same time, it is only necessary to open the electric cylinder 5. At this time, the piston rod of the electric cylinder 5 will push the first sliding plate 2 to move horizontally away from or towards the hinge point between the kiln door 4 and the furnace body 1. At this time, the first sliding plate 2 will drive the second sliding plate 3 to move synchronously through the connecting plate 6.

[0026] As shown in Figures 1 and 2, the first pushing component includes support plates 7 that are horizontally arranged on the side of the first sliding plate 2 and the second sliding plate 3 near the kiln door 4. The upper and lower ends of the kiln door 4 are provided with inclined grooves 8 along the length of the kiln door 4. One end of each groove 8 is inclined away from the furnace body 1. The ends of each groove 8 near the furnace body 1 are connected to one side of the kiln door 4. The kiln door 4 is located between the two support plates 7, and the ends of each support plate 7 near the kiln door 4 are provided with vertical push columns 9. The ends of each push column 9 away from the support plate 7 are respectively located in the two grooves 8.

[0027] As shown in Figures 1 and 2, during the process of closing the kiln door 4, the pusher 9 will approach the slide 8. As the kiln door 4 closes, the pusher 9 will enter the slide 8 from the end of the slide 8 that connects to the kiln door 4. Then the pusher 9 will contact one side wall of the slide 8. At this time, the kiln door 4 can no longer close. Then, the power component pushes the first sliding plate 2 and the second sliding plate 3 away from the hinge point between the kiln door 4 and the furnace body 1, so that the pusher 9 enters between the two opposite walls of the slide 8 (as shown in Figure 4). At this time, through the cooperation of the first sliding plate 2 and the second sliding plate 3, the two support plates 7, the two slides 8 and the two pushers 9, the kiln door 4 can be restricted, so that it cannot rotate due to vibration or external influence.

[0028] When it is necessary to completely close the kiln door 4, the power component continues to push the first sliding plate 2 and the second sliding plate 3 away from the hinge point between the kiln door 4 and the furnace body 1. At this time, because the slide 8 is set at an inclination, the kiln door 4 can be completely closed by the cooperation of the push column 9 and the slide 8.

[0029] When the ceramic firing in the furnace body 1 is completed and the kiln door 4 needs to be opened slightly for cooling, the first sliding plate 2 and the second sliding plate 3 are pushed close to the hinge point between the kiln door 4 and the furnace body 1 by the power component. At this time, the kiln door 4 can be opened slightly for heat dissipation and cooling by the cooperation of the push column 9 and the slide groove 8.

[0030] As shown in Figure 4, a sliding table 10 is horizontally slidably connected to the top of the furnace body 1. The sliding table 10 slides towards or away from the kiln door 4. A suspension plate 12 is provided above the side of the sliding table 10 that is close to the kiln door 4, and a ventilation mechanism is provided on the suspension plate 12. The second sliding plate 3 is located below the suspension plate 12. When the second sliding plate 3 moves horizontally, a second pushing member is provided on the second sliding plate 3 to push the sliding table 10 to move horizontally towards or away from the kiln door 4.

[0031] As shown in Figure 4, when the second sliding plate 3 moves away from the hinge point between the kiln door 4 and the furnace body 1, causing the kiln door 4 to be completely closed, the second sliding plate 3 will push the slide table 10 away from the kiln door 4 through the second pusher. At this time, the suspension plate 12 and the exhaust mechanism will move with the slide table 10. When the kiln door 4 is completely closed, the exhaust mechanism on the suspension plate 12 will be completely above the furnace body 1.

[0032] When the second sliding plate 3 approaches the hinge point between the kiln door 4 and the furnace body 1, causing the kiln door 4 to open slightly for heat dissipation and cooling, the second pusher pushes the sliding table 10 closer to the kiln door 4, so that the exhaust mechanism is located above the gap between the kiln door 4 and the furnace body 1. At this time, the exhaust mechanism extracts air between the kiln door 4 and the furnace body 1.

[0033] As shown in Figures 1, 3, and 7, the second pusher includes a fixed plate 13 disposed at the top of the furnace body 1, and the fixed plate 13 is located on the side of the slide table 10 away from the suspension plate 12. A compression spring 14 is provided between the fixed plate 13 and the slide table 10. A right-angled triangular plate 15 is provided on the slide table 10 below the suspension plate 12, and the inclined surface of the right-angled triangular plate 15 faces the second slide plate 3. The end of the second slide plate 3 near the right-angled triangular plate 15 is in contact with the inclined surface of the right-angled triangular plate 15.

[0034] As shown in Figures 1 and 3, when the second sliding plate 3 moves away from the hinge point between the kiln door 4 and the furnace body 1, causing the kiln door 4 to be completely closed, the second sliding plate 3 will push the right-angled triangle plate 15 through the inclined surface of the right-angled triangle plate 15, causing the slide table 10 to move away from the kiln door 4. At this time, the compression spring 14 is compressed, so that when the kiln door 4 is completely closed, the exhaust mechanism on the suspension plate 12 is completely above the furnace body 1.

[0035] When the second sliding plate 3 approaches the hinge point between the kiln door 4 and the furnace body 1, causing the kiln door 4 to open slightly for heat dissipation and cooling, the compressed spring 14 will push the slide table 10 closer to the kiln door 4, so that the exhaust mechanism on the suspension plate 12 is positioned above the gap between the kiln door 4 and the furnace body 1 (as shown in Figure 4). At this time, by adjusting the degree of opening of the kiln door 4, the exhaust position of the exhaust mechanism above the gap between the kiln door 4 and the furnace body 1 can be adjusted. When the kiln door 4 is fully opened, the compressed spring 14 is in its natural state, and the second sliding plate 3 separates from the inclined surface of the right-angled triangular plate 15.

[0036] As shown in Figures 1, 3, and 7, the ventilation mechanism includes several vertical cylinders 18 vertically arranged on the side of the suspension plate 12 away from the slide table 10. Each vertical cylinder 18 is spaced apart along the length of the suspension plate 12. Each vertical cylinder 18 is provided with a bracket 19, and each bracket 19 is rotatably connected to a fan 20. Each fan 20 is coaxially provided with a drive shaft 21. The slide table 10 is provided with a drive component for simultaneously driving each drive shaft 21 to rotate.

[0037] As shown in Figures 1, 3, and 7, when the second sliding plate 3 approaches the hinge point between the kiln door 4 and the furnace body 1, causing the kiln door 4 to open slightly for heat dissipation and cooling, the vertical cylinder 18 is located above the gap between the kiln door 4 and the furnace body 1 (as shown in Figure 4). At this time, the driving components simultaneously drive each driving shaft 21 to rotate, and each driving shaft 21 simultaneously drives each fan 20 to rotate, thus allowing air to be drawn between the kiln door 4 and the furnace body 1.

[0038] As shown in Figures 1, 3, 7, and 8, the top of each drive shaft 21 extends beyond the vertical cylinder 18. The drive components include first sprockets 23, each set at the top of the drive shaft 21, with the first sprockets 23 staggered vertically. The slide table 10 is provided with an inverted U-shaped fixing frame 24, and a rotating shaft 25 is rotatably connected between the top of the fixing frame 24 and the slide table 10. Several second sprockets 26 are coaxially arranged on the rotating shaft 25, with the number of second sprockets 26 being the same as the number of first sprockets 23. The second sprockets 26 are connected to the first sprockets 23 by a chain 27. The fixing frame 24 is provided with a motor 28 for driving the rotating shaft 25 to rotate.

[0039] As shown in Figures 9 and 10, a treatment box 34 containing water is provided on one side of the outer wall of the furnace body 1. The opening of the treatment box 34 is closed by a cover plate 35, and an exhaust port 36 is provided on the cover plate 35. The end of the exhaust pipe 37 away from the furnace body 1 passes through the cover plate 35 and extends into the water inside the treatment box 34. A furnace cover 38 for sealing the furnace opening of the firewood combustion furnace 32 is hinged on the firewood combustion furnace 32. Several air inlets 39 are provided on the side of the firewood combustion furnace 32 away from the furnace cover 38. A sliding cover 40 for sealing each air inlet 39 is horizontally slidably connected to the firewood combustion furnace 32.

[0040] An air pump (not shown in the figure) can be installed on the exhaust pipe 37 to facilitate the discharge of flue gas into the water in the treatment box 34. A drain pipe with a valve (not shown in the figure) is connected to the lower side of the treatment box 34 to facilitate the replacement of the water in the treatment box 34. The wood-burning stove 32 is equipped with an electric cylinder (not shown in the figure) for pushing the sliding cover 40 to move horizontally. When the electric cylinder is opened, the piston rod of the electric cylinder will push the sliding cover 40 to move horizontally, adjusting the number of air inlets 39 closed, without the need for manual pulling of the sliding cover 40.
