Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, and in particular to a drying oven with a rapid cooling function. Background Technology

[0002] In industrial production, drying ovens are commonly used material handling equipment, widely applied in industries such as chemicals, food, and building materials. Their main function is to dry materials by evaporating moisture or other volatile substances through heating. However, materials are usually at high temperatures after drying. If they are not cooled quickly and promptly, it will not only affect the efficiency of subsequent processing, such as the inability to collect, package, or further process the materials in a timely manner, but may also adversely affect the quality of the materials. Therefore, cooling operations are necessary for the drying ovens.

[0003] Existing drying ovens typically use cold air blowing for cooling during the drying process. The fans or cooling pipes are usually fixed to the outside of the oven, making the overall structure bulky. The cooling device cannot function as an independent unit for cooling and heat dissipation, hindering convenient disassembly and assembly, and impacting the ease of operation. Furthermore, the heat dissipation methods of drying ovens often involve simple heat sinks on the outside of the oven body or just a few ventilation openings for air convection. This cooling method cannot quickly remove heat from the oven and materials, resulting in excessively long cooling times. The rapid heat dissipation and heat adjustment capabilities of the drying oven are relatively poor, making the cooling method inefficient and the cooling time long, thus affecting subsequent production efficiency and increasing production costs. Therefore, we propose a drying oven with rapid cooling function to solve the above problems. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Please see Figures 1-6 A drying oven with rapid cooling function includes a drying oven body 1, and an air-cooling rack 2 is provided on the outer side of the drying oven body 1.

[0029] Multiple air-cooled blowing components 3 are provided on both sides of the air-cooled frame 2, and air-cooled flow guiding components 4 connected to the air-cooled blowing components 3 are provided on both sides of the drying oven body 1, and hot air outlet components 5 are provided on the top of the drying oven body 1.

[0030] Among them, the main body 1 of the drying oven is equipped with a temperature monitoring and control component 6, and the top of the air-cooled frame 2 is equipped with an air cooler 7 that is connected to multiple air-cooled blowing components 3.

[0031] The beneficial effects of this solution are as follows: Air-cooled air-blowing components 3 are provided on both sides of the air-cooled frame 2. The air-cooled air-blowing components 3 can blow external air-cooled pressurized cooling into the air-cooled air-guiding component 4, and blow high-speed flowing cold air into the drying oven body 1 for rapid air-blowing cooling. Then, the hot air outlet component 5 blows the hot air out of the oven body, thereby achieving rapid hot and cold air interaction for heat dissipation. The temperature monitoring and control component 6 can measure and control the oven body temperature. When the oven body heats up to the specified temperature, the air cooler 7 can be controlled to generate cold air and blow it into the air-cooled air-blowing component 3, which reduces the temperature of the cold air blown out by the air-cooled air-blowing component 3, greatly accelerating the oven body temperature cooling efficiency. While ensuring efficient heat dissipation, it can also prevent the oven body from cracking due to contact between the high-heat oven body and the low-temperature air.

[0032] The bottom support legs of the air-cooled frame 2 are equipped with casters 21, which facilitates the movement and displacement of the air-cooled frame 2. The air-cooled blower assembly 3 and the air-cooled airflow guide assembly 4 are connected in a movable manner, which is convenient for disassembly and assembly. The air-cooled frame 2, the air-cooled blower assembly 3 and the air-cooled machine 7 are a whole cooling device. When cooling is not required, disassembly and assembly are convenient, allowing the device to adjust the heat dissipation temperature according to temperature changes. It has good rapid cooling capacity, high heat dissipation uniformity, and convenient disassembly and assembly of heat dissipation components, which is convenient for construction and use.

[0033] Furthermore, the main body 1 of the drying oven is installed on the inner side of the air-cooled frame 2, and multiple air-cooled blowing components 3 are connected to the air-cooled flow guide component 4 and the main body 1 of the drying oven and the hot air outlet component 5. The bottom of the air-cooled frame 2 is provided with casters 21.

[0034] Specifically, the bottom support legs of the air-cooled frame 2 are equipped with casters 21, which facilitates the movement and displacement of the air-cooled frame 2, making the overall movement of the cooling equipment convenient, suitable for mobile operation, and easy to use.

[0035] Furthermore, the air-cooled blower assembly 3 includes an air-cooled air hopper 31, a flow guide pipe 32, and a blower 33. The blower 33 is installed on the inner side of the air-cooled air hopper 31, and the air-cooled air hopper 31 is fixedly installed on both sides of the air-cooled frame 2. One end of the flow guide pipe 32 is installed on the air-cooled air hopper 31, and the other end of the air-cooled air hopper 31 is sleeved and sealed on the air-cooled flow guide assembly 4.

[0036] Specifically, the blower 33 can pressurize external air and blow it into the air-cooled hopper 31 when blowing air. Since the air-cooled hopper 31 is funnel-shaped, it plays the role of blowing cold air when pressurizing. The end of the air-cooled hopper 31 is provided with a flow guide pipe 32, which can be sleeved on the air-cooled flow guide component 4. The air-cooled flow guide component 4 blows the high-speed flowing cold air into the drying oven body 1 for rapid blowing and cooling. Then, the hot air outlet component 5 blows the hot air out of the oven body, thereby achieving rapid hot and cold air interaction for heat dissipation, rapid heat dissipation of the oven body, high heat dissipation efficiency, and good heat dissipation uniformity.

[0037] Furthermore, the air-cooled flow guiding component 4 includes a flow guiding heat-resistant pipe 41 and a switch plate 42. One end of the flow guiding heat-resistant pipe 41 is connected to and fixed to the side of the drying oven body 1, and the other end of the flow guiding heat-resistant pipe 41 is connected to the air-cooled blower component 3. The switch plate 42 is inserted into the flow guiding heat-resistant pipe 41, and a ventilation flow guiding hole 43 is provided on the switch plate 42.

[0038] Specifically, one end of the heat-resistant guide pipe 41 is connected to the heat-connecting pipe 32 to facilitate airflow connection. A switch plate 42 is inserted into the heat-resistant guide pipe 41. The switch plate 42 has corresponding ventilation guide holes 43. When the main body of the drying oven 1 is performing drying operations, the heat-resistant guide pipe 41 can be closed by the switch plate 42. When cooling operations are required, the switch plate 42 can be pulled to connect the ventilation guide holes 43 on the switch plate 42 with the inner diameter of the heat-resistant guide pipe 41, thereby allowing the cold air in the heat-resistant guide pipe 41 to be quickly blown into the main body of the drying oven 1, completing the cold air blowing in, which is convenient to use.

[0039] Furthermore, a positioning lifting sleeve 44 is slidably sleeved on the switch plate 42, and the diameter of the ventilation guide hole 43 is smaller than the inner diameter of the heat-resistant guide pipe 41.

[0040] Specifically, the switch plate 42 can be positioned and fixed by the positioning and lifting sleeve 44 on the switch plate 42, which facilitates the lifting and fixing of the switch plate 42. The positioning and lifting sleeve 44 can be interference-fitted to the switch plate 42 and can slide up and down at the switch plate 42, making adjustment and operation convenient.

[0041] Furthermore, the hot air outlet assembly 5 includes an outlet pipe 51, an outlet anti-scalding pipe 52, and an anti-scalding insert 53. The outlet pipe 51 is fixed to the top of the drying oven body 1. The outlet anti-scalding pipe 52 is connected to the top of the outlet pipe 51. The outlet anti-scalding pipe 52 extends out to the air cooling frame 2. The air cooling frame 2 is made of flexible hose. The anti-scalding insert 53 is inserted and positioned on the side of the outlet pipe 51.

[0042] Specifically, the hot air inside the furnace can be discharged to the outside of the furnace through the outlet pipe 51 and the air outlet anti-scalding pipe 52. The air outlet anti-scalding pipe 52 can discharge the hot air into the air to prevent the hot air from harming the workers. The anti-scalding plate 53 plays the role of opening and closing the outlet pipe 51, which facilitates the switching between drying and cooling operations of the furnace.

[0043] Furthermore, the temperature monitoring and control component 6 includes a temperature detector 61 and a switch controller 62. Both the temperature detector 61 and the switch controller 62 are installed on the outside of the drying oven body 1. The output terminal of the temperature detector 61 is electrically connected to the input terminal of the switch controller 62. The output terminal of the switch controller 62 is electrically connected to the air-cooled blower component 3 and the air cooler 7, respectively.

[0044] Specifically, the temperature detector 61 can measure and monitor the temperature of the oven body 1 in real time. Then, the switch controller 62 controls the operation of the air-cooled blower assembly 3 and the air cooler 7. The air cooler 7 is controlled to run and generate cold air. The cold air is then discharged from the cold air outlet box 71 on the air cooler 7 and evenly and quickly blown into the air-cooled blower assembly 3 through the cold air output pipes 72 on both sides. This reduces the temperature of the cold air blown out by the air-cooled blower assembly 3 and greatly accelerates the cooling of the temperature inside the oven body 1.

[0045] Furthermore, the air cooler 7 is fixedly installed on the top of the air cooler frame 2. Both sides of the air cooler 7 are provided with cold air outlet boxes 71. Both cold air outlet boxes 71 are provided with multiple cold air output pipes 72. The multiple cold air output pipes 72 are respectively connected to the pipe bodies of multiple air-cooled blower components 3.

[0046] Specifically, the air cooler 7 can perform air cooling. The cooled air can be introduced into the cold air output pipe 72 through the cold air outlet box 71. The multiple cold air output pipes 72 are guided to the multiple air-cooled blowing components 3, which reduces the temperature of the cold air blown out by the air-cooled blowing components 3 and greatly accelerates the temperature cooling inside the drying oven body 1.

[0047] How to use and how to work this device:

[0048] By providing an air-cooled frame 2 on the outside of the main body 1 of the drying oven, and providing casters 21 on the bottom legs of the air-cooled frame 2, the movement and displacement of the air-cooled frame 2 can be facilitated.

[0049] Air-cooled air-blowing components 3 are provided on both sides of the air-cooled frame 2. The air-cooled air-blowing components 3 include an air-cooled air hopper 31, a flow guide pipe 32, and a blower 33. When blowing air, the blower 33 can pressurize the external air and blow it into the air-cooled air hopper 31. Since the air-cooled air hopper 31 is funnel-shaped, it plays the role of blowing cold air when the air is pressurized. The flow guide pipe 32 is provided at the end of the air-cooled air hopper 31. The flow guide pipe 32 can be sleeved on the air-cooled flow guide component 4. The air-cooled flow guide component 4 blows the high-speed flowing cold air into the drying oven body 1 for rapid air blowing and cooling. Then, the hot air outlet component 5 blows the hot air out of the oven body, thereby achieving rapid hot and cold air interaction for heat dissipation and rapid heat dissipation of the oven body.

[0050] The air-cooled airflow guiding assembly 4 includes an airflow guiding heat-resistant pipe 41 and a switch plate 42. One end of the airflow guiding heat-resistant pipe 41 is connected to the airflow connecting pipe 32 to facilitate airflow connection. The switch plate 42 is inserted into the airflow guiding heat-resistant pipe 41 and can be positioned and fixed by the positioning and lifting sleeve 44 on the switch plate 42. The switch plate 42 is provided with ventilation guiding holes 43. When the drying oven body 1 is performing drying operations, the airflow guiding pipe 41 can be closed by the switch plate 42. When cooling operations are required, the switch plate 42 can be pulled to make the ventilation guiding holes 43 on the switch plate 42 connect with the inner diameter of the airflow guiding heat-resistant pipe 41, so that the cold air in the airflow guiding heat-resistant pipe 41 can be quickly blown into the drying oven body 1 to complete the cold air blowing in.

[0051] Furthermore, since the heat-resistant guide pipe 41 and the guide connecting pipe 32 are movably connected, the overall air-cooled frame 2 can be easily disassembled and moved, and the disassembly and assembly operations are convenient. The air-cooled frame 2, the air-cooled blower assembly 3 and the air-cooled machine 7 are an integrated cooling device. When cooling operations are not required, the integrated cooling device can be removed, and the disassembly and assembly are convenient.

[0052] The top of the drying oven body 1 is equipped with a temperature monitoring and control component 6, which can measure and control the oven body temperature. When the air-cooled blower component 3 blows air, it reduces the temperature of the drying oven body 1 from a high temperature state to a non-high temperature state. The temperature monitoring and control component 6 directly measures the temperature and controls the air cooler 7 to run and generate cold air. The cold air is then discharged from the cold air outlet box 71 on the air cooler 7 and evenly blown into the air-cooled blower component 3 through the cold air output pipes 72 on both sides. This reduces the temperature of the cold air blown out by the air-cooled blower component 3 and greatly accelerates the cooling of the temperature inside the drying oven body 1.

[0053] The hot air exhaust assembly 5 serves to exhaust hot air. It includes an outer exhaust pipe 51, an anti-scalding exhaust pipe 52, and an anti-scalding insert 53. Hot air inside the furnace can be exhausted to the outside of the furnace through the outer exhaust pipe 51 and the anti-scalding exhaust pipe 52. The anti-scalding exhaust pipe 52 can exhaust hot air into the air to prevent hot air from harming workers. The anti-scalding insert 53 acts as an open and close valve for the outer exhaust pipe 51, facilitating the switching between drying and cooling operations of the furnace. It is convenient to use and allows the device to adjust the heat dissipation temperature according to temperature changes. It has good rapid cooling capacity, high heat dissipation uniformity, and the overall assembly and disassembly of the heat dissipation device are convenient for construction and use.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
