Abstract
Description
Technical Field
[0001] This utility model belongs to the field of gas catalytic infrared heating technology, specifically relating to a gas catalytic infrared heating furnace device with zoned control. Background Technology
[0002] Gas-fired catalytic infrared heating technology is a flameless heating technology based on the catalytic oxidation reaction of combustible gases such as natural gas and liquefied petroleum gas. It releases heat through infrared waves and has broad application prospects in fields such as industrial baking. Currently, existing gas-fired infrared radiation furnaces usually adopt a box-type or parallel layout. In this type of layout, the contact area between the radiation area and the workpiece is relatively small during the workpiece baking process, which makes the workpiece heat up slowly and the baking time longer, resulting in difficulty in improving baking efficiency and failing to meet the needs of high-efficiency production.
[0003] Meanwhile, existing gas-fired catalytic infrared radiation panels generally control their output power through pulse control valve groups. Although the infrared radiation panels can be started and stopped individually, they lack regional start and stop control functions. This means that in practical applications, it is impossible to target the infrared radiation panels in different areas according to the specific location, shape, or baking requirements of the workpiece. All workpieces can only use the same baking parameters during the baking process, and the infrared radiation panels output the same proportion of power. This not only leads to energy waste and increases production costs, but also fails to achieve precise baking of different workpieces, affecting the baking quality. For workpieces with different shapes, different heat distribution and power output may be required in different areas, but existing technology cannot meet this requirement and can only output a uniformly high power, resulting in excessive energy consumption. In summary, there is an urgent need for a gas-fired catalytic infrared heating furnace device with zoned control. Utility Model Content

Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0016] like Figure 1As shown, this utility model discloses a zone-controlled gas catalytic infrared heating furnace device. The infrared heating furnace device is set inside a furnace frame 100. The furnace frame 100 and the furnace body 8 are made of high-temperature resistant material. The zone-controlled gas catalytic infrared heating furnace device includes a furnace body 8, a plurality of first infrared radiation plates 1 symmetrically arranged inside the furnace body 8, a plurality of third infrared radiation plates 3 arranged below the first infrared radiation plates 1, and a plurality of second infrared radiation plates 2 arranged between the first infrared radiation plates 1 and the third infrared radiation plates 3. The plurality of second infrared radiation plates 2 and the plurality of third infrared radiation plates 3 are symmetrically arranged inside the furnace body 8. A plurality of mutually symmetrical support platforms 9 are set at the bottom of the inner side of the furnace body 8. An inclined surface 7 is set on the support platform 9, and the third infrared radiation plates 3 are set on the inclined surface 7. By horizontally arranging the plurality of first infrared radiation plates 1, the top of the workpiece 300 can obtain uniform heat radiation, providing a basic temperature guarantee for the subsequent heating of the middle and lower zones. By horizontally arranging the plurality of second infrared radiation plates 2, the middle of the workpiece 300 can obtain uniform heat radiation. To achieve uniform heat radiation, multiple third infrared radiation plates 3 are arranged at an angle to increase the contact area between the bottom radiation energy and the bottom surface of the workpiece 300, thus compensating for the low heating efficiency of the bottom of traditional heating furnaces. This is especially suitable for processing scenarios where the bottom surface of the workpiece 300 requires high heating. At the same time, the partitioned layout of each infrared radiation plate, combined with different angle designs, can form a three-dimensional heat radiation field in the entire baking cavity, avoiding the heating blind spots existing in traditional heating furnaces and ensuring that the workpiece 300 is heated from all directions without dead angles. The first infrared radiation plate 1, the second infrared radiation plate 2, and the third infrared radiation plate 3 are respectively connected to the first pulse control valve 4, the second pulse control valve 5, and the third pulse control valve 6. The first pulse control valve 4, the second pulse control valve 5, and the third pulse control valve 6 are used to control the operation of the first infrared radiation plate 1, the second control plate, and the third control plate, respectively. The furnace body 8 is equipped with a main control module (not shown in the figure), and the first pulse control valve 4, the second pulse control valve 5, and the third pulse control valve 6 are all electrically connected to the main control module.
[0017] Furthermore, in the zone-controlled gas catalytic infrared heating furnace device of this utility model, the main control module is used to control the start and stop of the first pulse control valve 4, the second pulse control valve 5, and the third pulse control valve 6 respectively.
[0018] As one specific implementation, in the zone-controlled gas catalytic infrared heating furnace device of this utility model, the number of first infrared radiation plates 1 is 2 to 4. The first infrared radiation plates 1 are set in the middle of the furnace body 8. More specifically, the number of first infrared radiation plates 1 is 2. Of course, the specific number of first infrared radiation plates 1 can be set according to the specific working conditions such as the size of the top of the workpiece 300 during actual use.
[0019] In one specific embodiment, in the zone-controlled gas catalytic infrared heating furnace device of this utility model, the number of second infrared radiation plates 2 is 4 to 8. The second infrared radiation plates 2 are arranged in the lower part of the furnace body 8. More specifically, the number of second infrared radiation plates 2 is 4. Of course, the specific number of first infrared radiation plates 1 can be set according to the specific working conditions such as the size of the middle part of the workpiece 300 during actual use.
[0020] As one specific implementation, in the zone-controlled gas catalytic infrared heating furnace device of this utility model, the number of third infrared radiation plates 3 is 2 to 4, more specifically, the number of third infrared radiation plates 3 is 2. Of course, the specific number of third infrared radiation plates 3 and the tilt angle of the inclined surface 7 can be set according to the specific working conditions such as the size and shape of the bottom of the workpiece 300 during actual use.
[0021] The working principle of this utility model's zone-controlled gas catalytic infrared heating furnace device is as follows:
[0022] The main control module is connected to a scanning and identification module. Before heating, heating parameters for different workpieces 300 can be preset. After the workpiece 300 is lifted into the furnace body 8 by the lifting equipment 200, the scanning and identification module identifies the type of workpiece 300 and sends the size parameters of workpiece 300 to the main control module. The main control module sends start and stop signals to the pulse control valves in the corresponding areas according to the preset parameters. In this way, the device can perform different heating modes according to different workpieces 300 in actual use. When the identification module detects that there is no workpiece 300 in the furnace, the main control module automatically reduces the power of all infrared radiation plates to 10%. At this time, all infrared radiation plates are in heat preservation state to avoid idling and energy consumption.
[0023] In summary, compared with the prior art, the zone-controlled gas catalytic infrared heating furnace device of this utility model has the following advantages and beneficial effects:
[0024] This device employs a unique funnel-shaped inclined surface 7 layout, allowing the third infrared radiation plate 3 to be installed at an angle on the inclined surface 7 of the support platform 9 at the bottom of the furnace body 8. This significantly increases the contact area between the radiation area and the workpiece 300. Compared to the traditional layout, the heating rate of the workpiece 300 is significantly improved, greatly enhancing baking efficiency and meeting the high-efficiency requirements of large-scale production. Furthermore, this device divides the infrared radiation plate into upper, middle, and lower zones, achieving independent zone control through the setting of various pulse control valves and a main control module. It automatically matches the baking parameters of different workpieces 300, dynamically adjusting the power of the infrared radiation plates in each zone for workpieces 300 with different shapes such as curved parts and flat parts, achieving precise heat distribution and ensuring baking quality.
