Description

Technical Field

[0001] This utility model discloses a heating mechanism for a waste gas treatment device, belonging to the technical field of waste gas treatment equipment. Background Technology

[0002] Kitchen waste refers to the waste generated in daily life, food processing, catering services, and catering services provided by institutions. Kitchen waste is often treated by incineration in waste treatment furnaces. The waste produced after incineration will generate a large amount of waste gas, which contains many harmful gases and needs to be treated before it can be directly discharged into the atmosphere.

[0003] Currently, the common process for treating waste gas requires high-temperature heating to decompose harmful gases at a certain temperature, thereby achieving purification. The heating element of general waste gas treatment devices uses tungsten wire as the heating source. However, for the treatment of waste gas from kitchen waste, very high temperatures are required. Therefore, heating devices often install a large number of heating wires. However, when tungsten wire is densely arranged, the center temperature is high, which can easily cause the heating wire to break, affecting the heating effect of the device and increasing the treatment cost.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a heating mechanism for a waste gas treatment device that can prevent the heating wire from melting, in order to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a heating box connected to a processing device, wherein the heating box has openings at both the top and bottom, a connecting plate is provided at the front end of the heating box, and a plurality of support rods are provided on both the left and right sides of the rear end of the connecting plate. The plurality of support rods extend to the rear end of the heating box and are arranged opposite each other in pairs. A plurality of support plates are arranged horizontally between the support rods in the heating box. A plurality of grooves are provided at both the top and bottom ends of the plurality of support plates. A plurality of heating wires are provided in the grooves of the support plates in the heating box. One end of each heating wire is connected to the connecting plate and the other end extends rearward. The plurality of heating wires are made of graphene and iron-chromium-aluminum alloy and are arranged alternately.

[0007] By adopting the above technical solution, the openings at the top and bottom of the heating box allow the exhaust gas to enter the heating box for heating after it is connected to the treatment device. The support rod, support plate, and grooves on the support plate allow the heating box to fix and connect the heating wires through the grooves, improving the stability and durability of the heating wire installation. At the same time, the support plate and grooves can separate several heating wires, increasing the heating area between the heating wires and preventing the heating wires from melting due to mutual heating. Graphene has excellent thermal conductivity, and iron-chromium-aluminum alloy also has good high temperature resistance and heating performance. The combination of the two can improve heating efficiency, allowing the exhaust gas to be heated to the required temperature more quickly in the treatment device, which is conducive to the exhaust gas treatment process. In addition, the heating wires of different materials have different specific heat capacities and can store different amounts of heat. With the staggered arrangement design, the heat received by the heating wires can be evenly distributed, further preventing the heating wire in the center from melting due to heat.

[0008] Preferably, each of the support plates is provided with an annular fixing ring in the groove, and the heating wire is disposed in the fixing ring.

[0009] By adopting the above technical solution, the setting of the fixing ring can ensure that the heating wire is stably fixed in the groove, avoid displacement or falling off during the heating process, and improve the working stability of the heating wire.

[0010] Preferably, the connecting plate is provided with a controller connected to the heating wire, and a control panel is provided on the front side of the connecting plate, the control panel being connected to the controller.

[0011] By adopting the above technical solution and setting the controller and control panel, the heating wire can be automatically controlled, making the control of the heating wire more convenient and efficient.

[0012] Preferably, a temperature sensor is provided at the front end of several of the heating wires, and the temperature sensor is connected to the control panel.

[0013] By adopting the above technical solution, the temperature of the heating wire can be monitored in real time through the setting of temperature sensors, and the heating temperature can be precisely controlled according to the needs of waste gas treatment, so as to avoid the adverse effects of excessively high or low temperatures on the waste gas treatment effect.

[0014] Preferably, the heating box is provided with a cover plate at both the upper and lower ends of the opening, the cover plate is provided with an air inlet, and the cover plate is provided with bolt holes for connecting with the processing device.

[0015] By adopting the above technical solution, this design enables the device to adapt to different working environments and facilitates connection and fixation with processing devices, thereby improving the convenience of operation.

[0016] Preferably, the connecting plate has several heat dissipation holes.

[0017] By adopting the above technical solution and setting several heat dissipation holes, the heat conducted from the heating wire to the connecting plate can be effectively reduced while ensuring the normal operation of the heating mechanism, preventing damage to components due to overheating, and further improving the reliability of the entire heating mechanism.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, by using heating wires made of graphene and iron-chromium-aluminum alloy in an alternating arrangement, the heating efficiency can be significantly improved. At the same time, the support plate inside the heating box can separate the heating wires. Combined with the design of alternating heating wires of the two materials, the mutual heating between the heating wires can be reduced, thereby effectively preventing the heating wires from melting during long-term operation.

[0020] Secondly, the heating mechanism is equipped with several support rods and support plates, as well as a ring-shaped fixing ring. These designs enhance the structural stability of the heating box. The support rods and support plates can evenly distribute the weight and heat of the heating wire, preventing the heating box from deforming or being damaged due to uneven heating. The fixing ring can ensure that the heating wire is stably fixed in the groove, avoiding displacement or falling off during the heating process.

[0021] Thirdly, the heating mechanism is equipped with a temperature sensor and control panel, which allows operators to monitor the temperature inside the heating chamber in real time and adjust it as needed. This not only improves the flexibility of the heating mechanism but also ensures the temperature stability during the waste gas treatment process, thereby improving the treatment effect.

[0022] Fourth, the heating box is equipped with cover plates at both the top and bottom, and bolt holes are provided on the cover plates for connecting with the processing device. This makes the heating mechanism easy to install and disassemble. At the same time, components such as heating wires and temperature sensors can be connected and replaced after the cover plates are removed, which facilitates maintenance and upkeep.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] A heating mechanism for a waste gas treatment device, such as Figures 1-2 As shown, the device includes a heating box 1 connected to a processing unit. The heating box 1 has openings at both its top and bottom, allowing exhaust gas to enter and be heated after connection to the processing unit. A connecting plate 2 is located at the front end of the heating box 1. Several support rods 3 are located on the left and right sides of the rear end of the connecting plate 2, extending to the rear end of the heating box 1. The support rods 3 are arranged opposite each other in pairs. Several support plates 4 are horizontally arranged between the support rods 3. Several grooves are located at both the top and bottom of the support plates 4. Several heating wires 5 are installed in the grooves on the support plates 4. One end of each heating wire 5 is connected to the connecting plate 2, and the other end extends rearward. The support rods 3, support plates 4, and grooves on the support plates 4 allow the heating box 1 to be fixed and connected to the heating wires 5, improving heating efficiency. The installation of the heating wires 5 ensures stability and durability. The support plate 4 and grooves separate the heating wires 5, increasing their heating area and preventing them from melting due to mutual heating. The heating wires 5 are made of graphene and iron-chromium-aluminum alloy, and are arranged alternately. Graphene has excellent thermal conductivity, while iron-chromium-aluminum alloy has good high-temperature resistance and heating performance. The combination of these materials improves heating efficiency, allowing the exhaust gas to be heated to the required temperature more quickly, thus facilitating the exhaust gas treatment process. Furthermore, the different materials of the heating wires 5 have different specific heat capacities and can store different amounts of heat. The alternating design ensures that the heat received by the heating wires 5 is evenly distributed, further preventing the central heating wire 5 from melting due to heat.

[0028] Several support plates 4 are each equipped with annular fixing rings 6 within their grooves. Heating wires 5 are positioned within these fixing rings 6. The fixing rings 6 ensure that the heating wires 5 are stably fixed within the grooves, preventing displacement or detachment during heating and improving the stability of the heating wires 5. A controller connected to the heating wires 5 is mounted on the connecting plate 2. A control panel 7 is mounted on the front side of the connecting plate 2 and is connected to the controller. Through the controller and control panel 7, automated control of the heating wires 5 is achieved, making the control of the heating wires 5 more convenient and efficient. Temperature sensors 8 are mounted on the front ends of several heating wires 5 and are connected to the control panel 7. The temperature sensors 8 allow for real-time monitoring of the temperature of the heating wires 5, enabling precise control of the heating temperature according to the requirements of waste gas treatment, and preventing excessively high or low temperatures from adversely affecting the waste gas treatment effect.

[0029] The heating box 1 has cover plates 9 at both the top and bottom ends with openings. The cover plates 9 have air inlets 10 and bolt holes 11 for connecting with the processing device. This design allows the device to adapt to different working environments and facilitates connection and fixation with the processing device, improving the convenience of operation. The connecting plate 2 has several heat dissipation holes 12. By setting several heat dissipation holes 12, while ensuring the normal operation of the heating mechanism, the heat conducted from the heating wire to the connecting plate 2 can be effectively reduced, preventing damage to components due to overheating, and further improving the reliability of the entire heating mechanism.

[0030] When the heating mechanism is used to treat the exhaust gas, it is connected to the treatment device through the bolt holes 11 on the two cover plates 9, so that the exhaust gas introduced into the treatment device can enter the heating box 1. Then, according to the type of exhaust gas to be treated, the preset heating temperature is adjusted through the control panel 7 and the heating wire 5 is controlled to work. At the same time, the temperature sensor 8 at the front end of the heating wire 5 can monitor the temperature inside the heating box 1 in real time and feed it back to the control panel 7, so that the heating box 1 can accurately heat the exhaust gas. The design of several heating wires 5 in the heating box 1, which are made of graphene and iron-chromium-aluminum alloy materials, can disperse the heat of the entire heating wire 5 and effectively avoid the impact of the heating wire 5 melting.
