Description

Technical Field

[0001] This utility model relates to the field of furnace plate technology, specifically a furnace plate. Background Technology

[0002] In food processing, multiple stages require high-temperature heating using boilers. These boilers typically require stable temperatures, so improvements to the boiler itself are necessary. Traditional gas combustion devices generally use a high-powered stove design, where combustible gas mixes with oxygen outside the burner for combustion. This method only drives the movement of the combustion gases without introducing additional oxygen. However, this method commonly suffers from insufficient mixing, low thermal efficiency, and safety hazards. Traditional combustion devices also premix the gas with air before delivering the premixed gas to the burner for combustion, resulting in high combustion efficiency. However, uneven mixing or backfire design in these devices increases the risk of failure.

[0003] Meanwhile, the contact pattern between the flame and the bottom of the pot is crucial to heat transfer efficiency. Fixed burners are difficult to adapt to pots with different curvatures, resulting in heat loss. In addition, uneven gas distribution can cause local blockages, which can further reduce combustion stability. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model proposes the following technical solution: A furnace tray includes an air pipe, on which a ring pipe frame for distributing gas is fixedly installed. Four gas distribution boxes are fixedly installed on the ring pipe frame, and the four gas distribution boxes are evenly distributed on the outer wall of the ring pipe frame. Multiple arc-shaped gas boxes for evenly distributing gas are fixedly installed on the gas distribution boxes. The ring pipe frame, gas distribution boxes, and arc-shaped gas boxes constitute a gas delivery pipeline.

[0005] Furthermore, the arc-shaped gas box is a quarter arc shape, and the arc-shaped gas boxes are evenly distributed on the gas distribution box. The diameters of the arc-shaped gas boxes on the gas distribution box are all different. Among the multiple arc-shaped gas boxes, the one closest to the ring pipe support has the smallest diameter, while the one farthest from the ring pipe support has the largest diameter.

[0006] Furthermore, the distance between the arc-shaped gas boxes and the annular pipe frame on the gas distribution box is also uniformly distributed. Among the multiple arc-shaped gas boxes, the arc-shaped gas box with the smallest diameter is closest to the annular pipe frame, and the arc-shaped gas box with the largest diameter is farthest from the annular pipe frame.

[0007] Furthermore, the ring frame is provided with multiple sets of gas delivery pipelines, each gas delivery pipeline including a gas pipe and a distribution ring pipe. The gas pipe and the distribution ring pipe are fixedly connected. The distribution ring pipe is fixedly connected to the bottom outer side of the arc-shaped gas box. The outer wall of the distribution ring pipe is fixedly connected to the gas distribution box. One distribution ring pipe and one gas pipe constitute a set of gas delivery pipelines.

[0008] Furthermore, the diameters of the rings formed by the diversion rings in the multiple sets of gas delivery pipelines are all different, and the diversion rings are fixedly connected to the corresponding arc-shaped gas boxes.

[0009] Furthermore, multiple connecting bolt tubes are fixedly installed on the diversion ring tube. Each connecting bolt tube has an internal through hole to facilitate the passage of gas. The connecting bolt tubes are evenly distributed on the diversion ring tube, and the number of connecting bolt tubes on the diversion ring tube increases with the diameter of the diversion ring tube. The connecting bolt tubes are set inside an arc-shaped gas box, and a heat-resistant cylinder is set inside the arc-shaped gas box. One end of the connecting bolt tube is set inside the heat-resistant cylinder.

[0010] Furthermore, the heat-resistant cylinder has multiple vent holes on its arc surface inside the arc-shaped air box. The vent holes on the heat-resistant cylinder are arranged horizontally on the heat-resistant cylinder, and the central axis of the heat-resistant cylinder is aligned with the central axis of the connecting bolt pipe.

[0011] Furthermore, a fixing nut is provided inside the heat-resistant cylinder. The fixing nut is connected to the outer wall of the connecting bolt tube by threads. The fixing nut and the connecting bolt tube confine the heat-resistant cylinder inside the arc-shaped gas box. The fixing nut is in the shape of a regular hexagonal prism and is provided with six gas holes. The gas holes on the fixing nut are arranged horizontally on the fixing nut.

[0012] The advantages of this utility model compared with the prior art are: (1) This device can not only improve the combustion efficiency of the gas by mixing oxygen and gas in a heat-resistant cylinder, but also allow the gas mixed with oxygen to burn directly without transportation or storage, thus reducing its risk factor; (2) This device uses a trapezoidal arc-shaped gas box to allow the flame after combustion to fit more closely to the arc-shaped pot surface, thereby allowing the outer flame of the flame to contact the bottom of the pot and improving the utilization rate of the gas.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] like Figures 1 to 4 As shown, a furnace plate includes an air pipe 101 and a gas pipe 201. One end of the air pipe 101 is connected to an external fan. A ring pipe frame 102 is fixedly installed on the air pipe 101. The ring pipe frame 102 is set for gas distribution. Four gas distribution boxes 103 are fixedly installed on the ring pipe frame 102. The four gas distribution boxes 103 are evenly distributed on the outer wall of the ring pipe frame 102. A bracket 104 is slidably installed on the outer wall of the gas distribution box 103. The bracket 104 is fixed to an external support frame by bolts during use. The gas distribution box 103 and the bracket 104 are also fixed by multiple bolts during use. By loosening these bolts, the position of the bracket 104 on the gas distribution box 103 can be adjusted, thereby facilitating the installation of the bracket 104.

[0027] like Figures 1 to 7 As shown, multiple arc-shaped gas boxes 105 for uniformly distributing gas are fixedly installed on the gas distribution box 103. The annular pipe frame 102, the gas distribution box 103, and the arc-shaped gas boxes 105 constitute a gas delivery pipeline. The arc-shaped gas boxes 105 are quarter-arc shapes and are evenly distributed on the gas distribution box 103. The diameters of the arc-shaped gas boxes 105 on the gas distribution box 103 are all different. Among the multiple arc-shaped gas boxes 105, the one closest to the annular pipe frame 102 has the smallest diameter, while the arc-shaped gas box 105 farthest from the annular pipe frame 102 has the smallest diameter. The arc-shaped gas box 105 has the largest diameter. It is worth noting that the curvature of all the arc-shaped gas boxes 105 must be kept the same to prevent uneven placement of the arc-shaped gas boxes 105. The distance between the arc-shaped gas boxes 105 and the annular tube frame 102 on the gas distribution box 103 is also evenly distributed to control the uniformity of heating of the pot bottom. The arc-shaped gas box 105 with the smallest diameter is closest to the annular tube frame 102, while the arc-shaped gas box 105 with the largest diameter is farthest from the annular tube frame 102. This is to ensure that the distance between the arc-shaped gas boxes 105 and the arc-shaped pot bottom is the same.

[0028] like Figure 5 and Figure 6 As shown, the gas pipe 201 consists of multiple pipes and a turning joint. One end of the gas pipe 201 is connected to an external gas delivery device. A diversion ring pipe 202 is fixedly installed at one end of the gas pipe 201. The diversion ring pipe 202 is fixedly connected to the bottom outer side of the arc-shaped gas box 105. The outer wall of the diversion ring pipe 202 is fixedly connected to the gas distribution box 103. One diversion ring pipe 202 and one gas pipe 201 form a gas delivery pipeline. This device includes multiple gas delivery pipelines. The diameters of the rings formed by the diversion ring pipes 202 in the multiple gas delivery pipelines are all different. The diversion ring pipe 202 with the smallest diameter is fixedly connected to multiple arc-shaped gas boxes 105 with the smallest diameter, while the diversion ring pipe 202 with the largest diameter is fixedly connected to multiple arc-shaped gas boxes 105 with the largest diameter.

[0029] like Figures 7 to 11As shown, multiple connecting bolt pipes 203 are fixedly installed on the diversion ring pipe 202. Each connecting bolt pipe 203 has an internal through hole to facilitate the passage of gas. The connecting bolt pipes 203 are evenly distributed on the diversion ring pipe 202, and the number of connecting bolt pipes 203 on the diversion ring pipe 202 increases with the diameter of the diversion ring pipe 202. The connecting bolt pipes 203 are disposed within an arc-shaped gas box 105, and a heat-resistant cylinder 205 is disposed within the arc-shaped gas box 105. The heat-resistant cylinder 205 is fixedly connected to the arc-shaped air box 105 by screws. Multiple vent holes are provided on the arc surface inside the arc-shaped air box 105. The vent holes on the heat-resistant cylinder 205 are horizontally arranged. The central axis of the heat-resistant cylinder 205 is aligned with the central axis of the connecting bolt tube 203. A fixing nut 204 is provided inside the heat-resistant cylinder 205. The fixing nut 204 is threadedly connected to the outer wall of the connecting bolt tube 203. 203. The heat-resistant cylinder 205 is confined within the arc-shaped gas box 105. One end of the connecting bolt tube 203 is located inside the heat-resistant cylinder 205. The fixing nut 204 is in the shape of a regular hexagonal prism and has six gas holes. The positions of the gas holes inside the heat-resistant cylinder 205 correspond to the positions of the vent holes. The six gas holes on the fixing nut 204 are arranged on six rectangular planes of the fixing nut 204. The gas holes on the fixing nut 204 are horizontally positioned on the fixing nut 204. In this configuration, during use, oxygen in the arc-shaped gas box 105 enters the heat-resistant cylinder 205 through the vent holes on the heat-resistant cylinder 205, while the gas in the diversion ring pipe 202 enters the fixing nut 204 through the connecting bolt pipe 203 and the six gas holes on the fixing nut 204. This allows the gas and oxygen to mix in the heat-resistant cylinder 205 before combustion, which can improve the combustion efficiency of the gas. A 107 is fixedly installed on the inner side of the ring pipe frame 102, and the 107 is used to ignite the device.

[0030] Working principle: When in use, this device supplies oxygen through air pipe 101 and gas through gas pipe 201. Multiple gas pipes 201 are installed on external gas pipes. When the device is in use, the oxygen supply device will be activated first. At this time, oxygen enters the ring pipe frame 102 through air pipe 101. Then, the oxygen is evenly distributed into each arc-shaped gas box 105 through the ring pipe frame 102 and the gas distribution box 103. Then, the oxygen forms a certain pressure in the arc-shaped gas box 105. Then, the oxygen enters the heat-resistant cylinder 205 through the vent on the heat-resistant cylinder 205. Finally, the oxygen will collect in each heat-resistant cylinder 205 and then rush out of the heat-resistant cylinder 205.

[0031] When oxygen rushes out of the heat-resistant cylinder 205, the gas also enters the gas pipe 201, and then enters the distribution ring pipe 202, thus filling the distribution ring pipe 202 with gas. The gas then enters the fixing nut 204 through the connecting bolt pipe 203 on the distribution ring pipe 202, and then rushes into the heat-resistant cylinder 205 through the gas hole on the fixing nut 204 to mix with the oxygen. After the gas and oxygen are mixed in the heat-resistant cylinder 205, they rush out of the heat-resistant cylinder 205. At this time, the gas mixed with oxygen can be ignited by 107 for combustion. The force of the oxygen and gas rushing out of the heat-resistant cylinder 205 together will keep the flame burning above the heat-resistant cylinder 205. This allows the gas and oxygen to mix and burn immediately after mixing in the heat-resistant cylinder 205, which not only ensures complete combustion of the gas, but also reduces the danger of the gas and oxygen mixture.

[0032] When shutting down this device, the gas supply is shut off first, followed by the oxygen supply. This allows the oxygen to carry away the residual gas inside the heat-resistant cylinder 205, while the pressurized oxygen also extinguishes the flame.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
