Description

Technical Field

[0001] This invention relates to heating equipment, and more particularly to a shuttle-type burner furnace for the burner process of MLCCs. Background Technology

[0002] Most existing end-burning furnaces are mesh belt end-burning furnaces, which are continuous production equipment with the advantages of high production efficiency and simple operation. They are widely used in atmosphere end-burning.

[0003] However, after its widespread use, the mesh belt furnace has also revealed many drawbacks, causing considerable trouble for users and manufacturers. These drawbacks include:

[0004] 1. As it is a semi-open furnace, it relies on the air curtain formed by continuous nitrogen injection to block outside air from entering the furnace. This results in a large amount of additional nitrogen support required for the production process, which greatly increases the production cost. This is particularly prominent for some products with small batches or experimental nature.

[0005] 2. A common problem with semi-open furnaces is that the furnace atmosphere is significantly affected by external factors. Changes in external temperature and pressure affect both the furnace temperature and pressure, which can lead to incomplete glue removal and cracking in the product. This necessitates that many companies place their firing furnaces in air-conditioned rooms to eliminate the influence of external temperature and pressure differences on the firing process in order to obtain high-quality products. Furthermore, to control the furnace atmosphere from external influences, additional equipment configurations are required, such as oxygen content sampling and atmosphere mass flow control, indirectly increasing equipment production costs.

[0006] 3. The continuous frictional movement of the mesh belt within the furnace leads to wear and tear on both the mesh belt and the furnace chamber. Replacing the mesh belt every 3-5 years represents a significant expense for the user. Furthermore, mesh belt structures place high demands on the manufacturer's manufacturing and debugging capabilities; otherwise, it will significantly impact equipment lifespan and the frequency of parts replacement.

[0007] 4. After prolonged use, the conveyor belt generates metal dust due to friction with the furnace chamber, which can affect the quality of some sensitive products. Additionally, the conveyor belt picks up dust during its return journey outside the furnace, which can also affect products inside the furnace. Therefore, the workshop where the equipment is located must be a cleanroom to prevent external dust from affecting the products and improve product quality.

[0008] 5. Maintenance is inconvenient. Replacement of insulation materials, furnace lining, and air intake structure all require specialized equipment from manufacturers, resulting in high maintenance costs and long repair times. Furthermore, cleaning the air intake furnace requires significant manpower and frequent cleaning.

[0009] Given the above shortcomings, it is important for small businesses, laboratories, and companies that pursue high quality to find a burner that meets the needs of low production capacity, is easy to maintain, energy-saving, and low-cost. Summary of the Invention

[0063] A shuttle-type burner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0064] refer to Figure 1 , Figure 2 and Figure 3 The present invention aims to provide an embodiment of a shuttle-type burner.

[0065] Structurally, this embodiment mainly includes a furnace car 100 and a furnace chamber 110. The furnace car 100 is used to transfer and carry the product to be heated, while the furnace chamber 110 forms a heating space to accommodate the furnace car 100.

[0066] Specifically, the furnace chamber 110 includes a furnace liner 120, a furnace body 130, and a furnace frame 150.

[0067] The furnace liner 120 is capable of accommodating the furnace car 100 or a portion thereof. The furnace liner 120 accommodating the furnace car 100 means that the entire furnace car 100 enters the furnace liner 120 and is then sealed with a door. The furnace liner 120 accommodating a portion of the furnace car 100 means that, in the illustration of this embodiment, only a portion of the furnace car 100 carrying a portion of the product enters the furnace liner 120, sufficient to meet usage requirements; it is not necessary for the entire furnace car 100 to enter the furnace liner 120.

[0068] As for the furnace body 130, the furnace body 130 is used to house the furnace liner 120, and the furnace body 130 can move relative to the furnace liner 120 to expose the furnace liner 120.

[0069] In other words, when it is necessary to heat the product, the product is placed on the furnace cart 100, and then a part of the furnace cart 100 is pushed into the furnace chamber 120. Next, the furnace body 130 is moved so that the furnace body 130 covers the furnace chamber 120. The heating components set in the furnace body 130, furnace frame 150, etc., heat the furnace chamber 120 to complete the heating and glue removal of the product.

[0070] After heating is completed, the furnace body 130 is moved first to cool down the furnace chamber 120, thereby rapidly reducing the temperature of the furnace cart 100 and the product. As a result, the furnace cart 100 is moved out of the furnace chamber 120 to reduce heat radiation to employees when taking products out and putting them in.

[0071] In summary, this embodiment, by setting up the furnace chamber 120, forms a furnace chamber inside the furnace chamber 120, creating a sealed cavity for containing products with a simple structure. This effectively prevents the influence of external airflow on the furnace atmosphere, saves nitrogen, reduces manufacturing difficulty, and facilitates use.

[0072] Secondly, by setting up the furnace body 130 in this embodiment, and making the furnace body 130 movable relative to the furnace chamber 120, on the one hand, the assembly of the furnace body 130 and the furnace chamber 120 can be carried out in two separate areas without affecting each other, which is convenient for assembly; on the other hand, the maintenance of the furnace body 130 and the furnace chamber 120 can be carried out in two separate areas without affecting each other, which is convenient for maintenance.

[0073] Furthermore, when the furnace body 130 is far from the furnace chamber 120, the furnace chamber 120 can be exposed to quickly reduce the product temperature, facilitate transportation, and at the same time, reduce the initial heating temperature to prevent the product from heating up too quickly and cracking, thus meeting the heating requirements.

[0074] In some preferred embodiments, the furnace chamber 110 may further include a furnace bottom 140, which is located at the bottom of the furnace shell 120. The furnace bottom 140 and the furnace body 130 cooperate to form a semi-enclosed cavity for accommodating the furnace shell 120.

[0075] Understandably, by setting the furnace bottom 140 in this embodiment, the furnace bottom 140 can cooperate with the furnace body 130 to form a semi-enclosed cavity, thereby reducing external heat dissipation, reducing energy consumption, and facilitating the heating of the furnace chamber 120 and the product to a suitable temperature.

[0076] In some preferred embodiments, the top of the furnace bottom 140 may abut against the bottom of the furnace liner 120.

[0077] Understandably, the furnace bottom 140 abuts against the furnace liner 120, which can support the furnace liner 120, prevent the furnace liner 120 from being suspended in the air, reduce the risk of deformation of the furnace liner 120, and enable the furnace liner 120 to support more products and be durable.

[0078] In some preferred embodiments, the furnace bottom 140 may have a lower heater.

[0079] Understandably, by setting up a lower heater in this embodiment, the number of heating positions can be increased, and multi-point heating can be achieved in conjunction with the furnace body 130, resulting in balanced heating and high efficiency.

[0080] In some preferred embodiments, the furnace bottom 140 may have a lower insulating brick.

[0081] Understandably, by setting up the lower insulating bricks in this embodiment, heat dissipation from the furnace bottom 140 can be reduced, heat loss can be reduced, and the ambient temperature can be lowered.

[0082] In some preferred embodiments, individual of the lower insulating bricks may abut against the furnace liner 120.

[0083] As can be understood, this embodiment facilitates heat diffusion by using individual lower insulating bricks to support the furnace 120, which means that the furnace 120 can be heated evenly, and it also facilitates subsequent maintenance and replacement of the lower heater.

[0084] In some preferred embodiments, the furnace chamber 110 may further include an L-shaped furnace frame 150, the furnace frame 150 having a horizontal portion 160 and a vertical portion 170, the vertical portion 170 for mounting the furnace liner 120, and the horizontal portion 160 for supporting the furnace body 130.

[0085] Understandably, in this embodiment, the furnace frame 150 is L-shaped, which facilitates the arrangement of the furnace liner 120 and the furnace body 130, making it easy to install and simplifying the layout.

[0086] In some preferred embodiments, the horizontal portion 160 may be positioned to house the furnace bottom 140.

[0087] It is understandable that the horizontal section 160 is set with the furnace bottom 140 so that the horizontal section 160 and the furnace bottom 140 partially overlap, making full use of space and resulting in a compact structure.

[0088] In some preferred embodiments, the horizontal portion 160 may be provided with a first guide rail that supports the furnace body 130.

[0089] Understandably, setting the first guide rail can reduce the resistance to the movement of the furnace body 130. At the same time, the first guide rail can be used to form the horizontal part 160, reducing the number of parts.

[0090] In some preferred embodiments, two first guide rails may be arranged side by side.

[0091] Understandably, by setting two first guide rails, the furnace body 130 can be supported on both sides, further reducing the resistance to the movement of the furnace body 130.

[0092] In some preferred embodiments, the two first guide rails can be disposed on opposite sides of the furnace liner 120.

[0093] It is understandable that placing the two first guide rails on opposite sides of the furnace liner 120 allows the furnace body 130 to move smoothly to the furnace liner 120, reducing movement resistance and preventing the furnace body 130 from tipping over.

[0094] In some preferred embodiments, the furnace body 130 may have a first roller that abuts against the first guide rail.

[0095] Understandably, by setting up the first roller, the contact area can be reduced, movement noise can be reduced, and it is also durable and easy to maintain.

[0096] In some preferred embodiments, the furnace chamber 110 may also include a power assembly 180 for moving the furnace body 130, the power assembly 180 including a power motor and a transmission chain.

[0097] Understandably, this embodiment sets up a power assembly 180, which includes a power motor and a transmission chain, thereby using chain drive to move the furnace body 130, which is convenient and quick, and the switching of the furnace body 130's direction of movement is very smooth.

[0098] In some preferred embodiments, the horizontal portion 160 may be provided with a front gear shaft and a rear gear shaft that support the transmission chain, with the front gear shaft located at the front end of the horizontal portion 160 and the rear gear shaft located at the rear end of the horizontal portion 160.

[0099] Understandably, this embodiment, by setting a front gear shaft and a rear gear shaft, can easily support the transmission chain and meet the layout requirements.

[0100] In some preferred embodiments, the power motor can be located at the bottom of the furnace body 130, and the power motor can be located at the end of the horizontal part 160 away from the vertical part 170, that is, the power motor can be located at the rear end of the horizontal part 160.

[0101] It is understandable that the motor is kept away from the furnace body 130, furnace liner 120 and furnace bottom 140 where they are heated, to avoid overheating and damage to the motor.

[0102] In some preferred embodiments, the furnace chamber 110 may also include a power assembly 180 for moving the furnace body 130, the power assembly 180 including a power motor, gears and racks.

[0103] Understandably, this embodiment forms a power assembly 180 by setting up a power motor, gears and racks, providing a variety of application forms.

[0104] In some preferred embodiments, an upper heater may be provided inside the furnace body 130.

[0105] Understandably, installing a heater inside the furnace body 130 can simultaneously heat the top of the furnace chamber 120, achieving rapid heating and even heating, while also being extremely convenient to arrange.

[0106] In some preferred embodiments, the furnace body 130 may have a plurality of first heat-insulating bricks, which form the inner surface of the furnace body 130, and the inner surface of the furnace body 130 includes the top wall and side wall of the furnace body 130.

[0107] Understandably, this embodiment can enhance the heat insulation effect and reduce heat loss by using several first heat insulation bricks, making it easier to concentrate energy to heat the products inside the furnace 120, so that the furnace 120 can have a higher heating temperature, such as 1000 degrees Celsius.

[0108] In some preferred embodiments, the first insulating brick and the lower insulating brick can be stacked vertically for heat insulation.

[0109] Therefore, the first insulating brick and the lower insulating brick work together to reduce the heat loss from the bottom of the furnace body 130.

[0110] In some preferred embodiments, the lower insulating brick may be fitted to form a protrusion, and the first insulating brick may be fitted to form a recess that accommodates the protrusion.

[0111] Therefore, by placing the insulating bricks, the lower insulating brick and the first insulating brick can overlap, which is simple to arrange and easy to implement.

[0112] Reference Figure 4 In some preferred embodiments, the furnace liner 120 may be provided with an exhaust pipe 190, the exhaust pipe 190 including a gas collecting pipe 200 located inside the furnace liner 120 and a gas outlet pipe 210 connected to the gas collecting pipe 200. The gas outlet pipe 210 is connected to the outside. The gas collecting pipe 200 is provided with a plurality of gas collecting holes 220.

[0113] Therefore, when the product is heated and the colloid is discharged, the gaseous colloid enters the gas collecting hole 220, and then is discharged through the gas collecting pipe 200 and the gas outlet pipe 210, reducing the colloid residue.

[0114] In some preferred embodiments, the gas outlet pipe 210 may include a vertical pipe and a horizontal pipe. The vertical pipe passes through the furnace liner 120 and is connected to the outside. The horizontal pipe is located inside the furnace liner 120. One end of the horizontal pipe is provided with a slag removal port and a plug to seal the slag removal port. The other end of the horizontal pipe is connected to the gas collecting pipe 200. The radial outer surface of the horizontal pipe is connected to the bottom end of the vertical pipe.

[0115] Therefore, by improving the design of the exhaust pipe 210, this embodiment facilitates exhaust and cleaning maintenance, while minimizing the impact on the operation of the furnace.

[0116] In some preferred embodiments, the gas collecting pipe 200 may be disposed on the top wall of the furnace 120, the gas outlet pipe 210 may extend along the length direction of the furnace 120, and the gas collecting pipe 200 may be disposed along the width direction of the furnace 120.

[0117] Therefore, this embodiment can extend the length of the gas collecting pipe 200 and expand the distribution area of ​​the gas collecting holes 220, making it convenient and quick to collect colloidal waste gas.

[0118] Meanwhile, this embodiment can reduce the space occupied by the exhaust pipe 190 through the above arrangement, and reduce the effective space inside the furnace 120 by a small amount, without affecting the product's load capacity.

[0119] In some preferred embodiments, the gas collecting pipe 200 may have a first bottom wall and two first side walls connecting opposite sides of the first bottom wall, with the top edge of the first side wall connected and fixed to the furnace liner 120.

[0120] Understandably, by setting the first bottom wall and the first side wall in this embodiment, the gas collecting pipe 200 can be easily formed, reducing the difficulty of manufacturing and layout. It also allows the gas collecting pipe 200 to serve as a structure to reinforce the furnace liner 120 and improve the strength of the furnace liner 120.

[0121] In some preferred embodiments, the first bottom wall may be provided with the air collection hole 220.

[0122] It is understandable that a gas collecting hole 220 is provided on the first bottom wall, which is convenient for processing and also facilitates the smooth entry of adhesive-containing gas into the gas collecting hole 220.

[0123] In some preferred embodiments, the first sidewall may be provided with a first notch, which, together with the furnace liner 120, forms a gas collecting hole 220.

[0124] Understandably, on the one hand, increasing the number of vent holes 220 improves exhaust capacity, and on the other hand, facilitates welding and fixing of the first sidewall to the furnace liner 120, reducing welding deformation.

[0125] In some preferred embodiments, the furnace liner 120 may be equipped with a thermocouple, and the detection end of the thermocouple may be fixed to the gas collecting pipe 200.

[0126] Understandably, this embodiment uses thermocouples to monitor the temperature inside the furnace chamber 120 in real time, preventing the product from being overheated or underheated.

[0127] In some preferred embodiments, one end of the thermocouple may be installed on the gas collecting pipe 200.

[0128] Understandably, placing the thermocouple in the gas collecting pipe 200 simplifies installation and allows the temperature measuring point to be closer to the center of the furnace for more accurate detection.

[0129] In some preferred embodiments, the furnace car 100 may include a rack 240 and a car body 230 connected to one side of the rack 240. The rack 240 is used to place products to be heated and overlaps the inner surface of the furnace liner 120.

[0130] In other words, in this embodiment, it is not necessary for the furnace car 100 to enter the furnace chamber 120 completely, nor is it necessary to set a furnace door. The furnace car 100 can be used to cooperate in achieving the sealing of the furnace chamber 120.

[0131] In some preferred embodiments, a second guide rail may also be included to support the vehicle body 230.

[0132] Understandably, by setting a second guide rail, the movement of the vehicle body 230 can be guided, the movement trajectory of the vehicle body 230 can be limited, and accidental collisions or bumps between the vehicle body 230 or the load rack 240 and the furnace liner 120 can be avoided.

[0133] In some preferred embodiments, the second guide rail may be made of angle steel.

[0134] It is understandable that using angle steel to manufacture the second guide rail makes it easier to lay and reduces manufacturing costs.

[0135] In some preferred embodiments, the furnace car 100 may include a rack 240 for placing products to be heated. The rack 240 is provided with an air inlet 250 and an air inlet pipe 260 connecting the air inlet 250. The air inlet is used to blow gas into the furnace liner 120.

[0136] Understandably, by providing an air outlet 250 in the carrier 240, this embodiment allows the gas to be closer to the product, thereby facilitating the release of the colloid and ensuring that the colloid is completely discharged.

[0137] In some preferred embodiments, the air intake pipe 260 may be arranged around the edge of the shelf 240, and the air intake pipe 260 may be provided with a plurality of air inlets 250.

[0138] In other words, on the one hand, the air inlet pipe 260 can form a guardrail to prevent the product from falling, and on the other hand, it can increase the number of air outlets 250 so that more products can be blown by the gas.

[0139] In some preferred embodiments, the furnace car 100 may include a rack 240 for placing products to be heated, and the rack 240 has a sealing portion 270 for sealing the furnace liner 120.

[0140] Understandably, this embodiment provides a sealing part 270, which works in conjunction with the furnace liner 120 to insulate against heat, reduce heat loss, and prevent the colloid from being directly released into the outside air.

[0141] In some preferred embodiments, the sealing portion 270 may include a first plug that matches the inner surface of the furnace liner 120.

[0142] Therefore, in a specific configuration, a first plug can be provided to form a sealing part 270, thereby achieving a matching seal in terms of contour.

[0143] In some preferred embodiments, the sealing portion 270 may include a first baffle located on the side of the first plug body near the furnace liner 120.

[0144] Therefore, in the specific design, the first baffle can participate in heat insulation without needing to match the inner shape of the furnace liner 120, while reducing the manufacturing difficulty.

[0145] In some preferred embodiments, a first baffle that cooperates with the first baffle body can be provided on the inner side of the furnace liner 120, and the first baffle body and the first baffle body cooperate to insulate against heat.

[0146] Therefore, by setting the first baffle in this embodiment, it can not only work with the first baffle body to provide heat insulation, but also provide internal support for the furnace liner 120, thereby reducing the deformation of the furnace liner 120.

[0147] In some preferred embodiments, the first baffle may be disposed on the top wall of the furnace liner 120.

[0148] Therefore, in this embodiment, the first baffle is set on the top wall of the furnace chamber 120, which does not affect the entry and exit of the rack 240, nor does it affect its use.
