Technical Field

[0001] This utility model relates to the field of cookware processing technology, and in particular to a device for durable curing treatment of cookware surfaces. Background Technology

[0002] Cookware processing involves multiple stages, including material handling, molding, surface coating, and curing. The equipment for cookware curing mainly involves curing ovens and related supporting equipment. Its core function is to achieve the physicochemical curing of coatings or materials by controlling temperature, time, and environmental conditions.

[0003] Currently, when curing ovens perform heat curing treatment on cookware coatings, the heat required for curing is generated by external energy input. The exhaust gas discharged through the waste gas treatment system still contains a large amount of unused waste heat. Due to the lack of heat recovery devices, the residual heat of these high-temperature exhaust gases cannot be recycled back into the curing oven through the heat exchange system, nor can it be converted into an auxiliary heat source for other processes, resulting in significant energy waste.

[0004] Therefore, this application proposes an apparatus for durable curing treatment of cookware surfaces. Utility Model Content

[0005] The present invention mainly addresses the technical problem of the inability to recover and utilize heat in the exhaust gas, resulting in energy waste, by providing a device for durable curing treatment of cookware surfaces.

[0007] Furthermore, the processing assembly also includes a partition plate and a connecting pipe. The partition plate is fixedly connected to the inner wall of the processing box in a spiral shape, and the connecting pipe is fixedly connected to the inner wall of the processing box. The exhaust pipe extends to the inner wall of the processing box and is connected to the center of the connecting pipe.

[0008] Furthermore, a filter plate for filtering exhaust gas is installed on the inner wall of the connecting pipe, and the filter plate has multiple filter holes arranged in a circular pattern.

[0009] Furthermore, the air intake assembly includes an air intake pipe and an air intake port. The air intake pipe is connected to the inner wall of the processing chamber, and the air intake port is fixedly connected to the end of the air intake pipe away from the processing chamber.

[0010] Furthermore, the emission assembly includes an emission pipe and a filter layer. The emission pipe is fixedly connected to the top of the curing oven body on the side away from the exhaust pipe, and a filter layer for filtering exhaust gas is installed on the top of the inner wall of the emission pipe.

[0011] Furthermore, the conveying assembly includes a second conveying pipe and two first conveying pipes.

[0022] Example 1: An apparatus for durable curing treatment of cookware surfaces, such as... Figure 1 As shown, the device includes a curing oven body 10. A conveyor belt 11 for conveying cookware is installed on the inner wall of the curing oven body 10. Specifically, a control center 12 for controlling the curing oven body 10 is installed on the side wall of the curing oven body 10. A sensor for detecting internal temperature and humidity is installed on the control center 12. A control button for operation is also installed on the control center 12. A curing component for heating and curing cookware is installed on the bottom inner wall of the curing oven body 10. When curing is required, the cookware is placed on top of the conveyor belt 11, and the control center 12 controls the conveyor belt 11 to move the cookware to the inner wall of the curing oven body 10. The control center 12 adjusts the temperature of the curing component to cure the cookware. After curing, the cookware can be removed from the curing oven body 10 along with the conveyor belt 11.

[0023] like Figure 2 and Figure 3 As shown, an exhaust pipe 20 for exhausting waste gas is installed on the top of the curing oven body 10. The exhaust pipe 20 has an L-shaped cross-section. A treatment component for recovering waste heat from the waste gas is installed on the top of the curing oven body 10 on one side of the exhaust pipe 20. The treatment component includes a treatment box 30 fixedly connected to the top of the curing oven body 10. The exhaust pipe 20 is connected to the treatment box 30. An air intake component for external air to enter is connected to the treatment box 30. The air is delivered to the treatment box 30 through the air intake component and heated by the heat of the waste gas to recover waste heat.

[0024] like Figure 4 and Figure 5 As shown, a conveying assembly for discharging exhaust gas and heated air is installed at the other end of the processing box 30, and a discharge assembly for treating and discharging exhaust gas is installed on the top side of the curing oven body 10 away from the exhaust pipe 20. The conveying assembly is connected to the curing oven body 10 and the discharge assembly. The exhaust gas after waste heat recovery can be discharged after being treated by the discharge assembly, and the heated air is conveyed to the curing oven body 10 through the conveying assembly to heat the curing oven body 10.

[0025] like Figure 2As shown, the processing assembly also includes a partition plate 31 and a connecting pipe 32. The connecting pipe 32 is made of copper. The partition plate 31 is fixedly connected to the inner wall of the processing box 30 in a spiral shape. The partition plate 31 fits against the inner walls on both sides of the processing box 30. The partition plate 31 can divide the space inside the processing box 30 into a spiral channel. The inner wall of the processing box 30 has a spiral fixed groove. The connecting pipe 32 is fixedly connected to the inner wall of the fixed groove on the processing box 30. The exhaust pipe 20 extends to the inner wall of the processing box 30 and is connected to the center of the connecting pipe 32. When the exhaust gas is discharged through the exhaust pipe 20, it can enter the center of the connecting pipe 32 through the exhaust pipe 20. The exhaust gas can then be transported along the spiral connecting pipe 32.

[0026] The inner wall of the connecting pipe 32 is equipped with a filter plate 33 for filtering exhaust gas. The filter plate 33 has multiple filter holes arranged in a circle. Impurities in the exhaust gas can be filtered through the filter holes, and the impurities in the exhaust gas can be pre-treated. When the exhaust gas passes through, the filter holes can force the gas to disperse, reduce the flow rate of the exhaust gas, and increase the residence time of the exhaust gas in the connecting pipe 32.

[0027] By using the connecting pipe 32 and the filter plate 33, the spiral design of the connecting pipe 32 and the dispersion of the exhaust gas by the filter plate 33 can increase the residence time of the exhaust gas in the connecting pipe 32, increase the time for heating the air, and thus improve the efficiency of heat recovery from the exhaust gas.

[0028] like Figure 3 As shown, the air intake assembly includes an air intake pipe 40 and an air intake port 41. The air intake pipe 40 is connected to the inner wall of the processing box 30, and the connection point of the air intake pipe 40 is located at the center of the channel inside the processing box 30. The air intake port 41 is trumpet-shaped and fixedly connected to the end of the air intake pipe 40 away from the processing box 30.

[0029] More specifically, the intake assembly also includes an intake channel 42 and overflow vents 43. The intake channel 42 is located at the connection between the intake pipe 40 and the intake port 41. The overflow vents 43 are linearly arranged and alternately located at both ends of the intake channel 42, and both ends of the overflow vents 43 are connected to the intake channel 42. The cross-section of the overflow vents 43 is arc-shaped at both ends, and the opening of the cross-section of the overflow vent 43 near the intake port 41 is smaller than the opening of the cross-section away from the intake port 41. Specifically, when gas in the intake port 41 enters through the intake channel 42, this... The small cross-section at the top of the overflow hole 43 prevents gas from entering the overflow hole 43. The gas can then enter the intake pipe 40 along the intake channel 42. When the gas in the intake pipe 40 is discharged, the large cross-section at the bottom of the overflow hole 43 allows the gas to enter the overflow hole 43. This creates an inflow and outflow within the overflow hole 43, preventing the gas in the intake pipe 40 from being discharged from the intake channel 42. This forms a one-way air intake, preventing hot air from being discharged from the intake port 41 and affecting the recovery and utilization of waste heat.

[0030] like Figure 5 As shown, the emission assembly includes an emission pipe 50 and a filter layer 51. The emission pipe 50 is fixedly connected to the top of the curing furnace body 10 on the side away from the exhaust pipe 20. The top of the inner wall of the emission pipe 50 is equipped with a filter layer 51 for filtering the exhaust gas. The filter layer 51 is made of activated carbon.

[0031] like Figure 4 As shown, the conveying assembly includes a second conveying pipe 61 and two first conveying pipes 60. The first conveying pipe 60 passes through the processing box 30 and is connected to the tail end of the connecting pipe 32. The other end of the first conveying pipe 60 is connected to the inner wall of the curing oven body 10. One end of each of the two first conveying pipes 60 is connected to the inner wall of the processing box 30. The other end of the second conveying pipe 61 is connected to the inner wall of the discharge pipe 50 and is located at the bottom of the filter layer 51. Multiple linearly arranged binding straps 62 are sleeved on the outer walls of the first and second conveying pipes 60 and 61, binding the second conveying pipe 61 and the first conveying pipe 60. Together, the heat from the exhaust gas in the second conveying pipe 61 can further heat the air in the first conveying pipe 60. The second conveying pipe 61 can then convey the exhaust gas to the discharge pipe 50, and after being filtered through the filter layer 51, it will be discharged. The first conveying pipe 60 can then convey the heated air to the curing oven body 10, heating the inner wall of the curing oven body 10. Since the gas inside the curing oven body 10 has a high heat value and the gas pressure of the hot gas is lower than that of the outside air, a negative pressure can be generated. Then, through the negative pressure, the air is drawn into the processing box 30 through the first conveying pipe 60, the processing box 30, and the air inlet pipe 40.

[0032] In summary, by using the processing components, conveying components, and air intake components, air can be drawn into the processing box 30 by the negative pressure of the hot gas inside the curing oven body 10. The heat of the waste gas is used to heat the air drawn into the processing box 30, and the heated air is then transported into the curing oven body 10 to heat the interior of the curing oven body 10. This allows for the recovery and utilization of the waste heat in the waste gas, reducing energy input.

[0033] The working principle of this utility model is as follows: When curing is required, the pot is placed on the conveyor belt 11. The control center 12 controls the conveyor belt 11 and the fixing components inside the curing oven body 10. The pot can then enter the curing oven body 10 with the conveyor belt 11 and be heated and cured by the curing components. After curing, the pot is then transported out by the conveyor belt 11.

[0034] At this time, the exhaust gas in the curing oven body 10 can be transported to the connecting pipe 32 in the processing box 30 through the exhaust pipe 20, and then transported to the processing box 30 through the air inlet 41 and the air inlet 32. The exhaust gas in the connecting pipe 32 heats the air, and the exhaust gas can be transported to the discharge pipe 50 through the second conveying pipe 61 and discharged after being filtered through the filter layer 51. The heated air can be transported to the curing oven body 10 through the first conveying pipe 60 to heat the curing oven body 10.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
