Description

Technical Field

[0001] The invention relates to the technical field of cooking utensils, in particular to an integrated meat-boiling boiler. Background Art

[0002] The production and processing of large quantities of meat products often requires long cooking times, consuming a lot of fuel. Existing meat cookers mostly use a split structure, separated from the stove. The pot is large, but the heated area at the bottom is relatively small, resulting in uneven heating. Prolonged overheating of the bottom can easily lead to the formation of a nodular oxide layer, reducing heat transfer efficiency. Split stoves have low thermal efficiency, poor air flow within the furnace during heating, and the flame is often oxygen-deficient, resulting in incomplete combustion. The high temperature of the flame is concentrated in a small, localized area for a long time, further reducing the utilization rate of thermal energy. When the meat cooker is large, the water temperature is higher in areas with better heat transfer performance and higher flame temperatures, while the water temperature is lower in areas with poor heat transfer performance and lower flame temperatures. This results in uneven temperature distribution within the pot, which can easily lead to undercooked or undercooked products. Summary of the Invention

[0003] In view of the above problems, the present invention provides an integrated meat-boiling boiler with high furnace combustion thermal efficiency, uniform heating of the pot bottom, low heat loss, and stable and reliable product quality.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows: the integrated meat cooking boiler described in the present invention includes an open pot, the bottom of the open pot is fixedly connected to a stove shell, and the inner cavity of the stove shell is provided with a furnace, an air uniforming plate and a return air duct. The air uniforming plate is a hollow plate arranged around the furnace, and the side wall of the air uniforming plate facing the furnace is provided with ventilation holes, and the blower is connected to the inner cavity of the air uniforming plate through a pipe; the return air duct is a U-shaped air duct tightly attached to the bottom of the open pot, one end of the return air duct is connected to the rear end of the furnace, and the other end is connected to the exhaust pipe.

[0005] The cross-section of the open pot is U-shaped, and the front end of the open pot is provided with a front end plate and the rear end is provided with a rear end plate. The lower ends of the front end plate and the rear end plate extend downward to respectively form the front and rear ends of the stove shell; the furnace is located in the middle below the open pot, and the front end of the furnace is provided with a furnace door installed on the front end plate at the front end of the stove shell. A uniform air plate parallel to the axis of the open pot is provided on each side of the furnace, and a partition is provided between the upper end of the uniform air plate and the bottom of the open pot.

[0006] The rear end of the stove shell is provided with a return air bin connected to the furnace and the return air duct, and the front end of the stove shell is provided with a smoke exhaust bin connected to the return air duct and the smoke exhaust pipe.

[0007] The bottom of the open pot is provided with axially distributed fins.

[0008] An induced draft fan is installed on the smoke exhaust pipe.

[0009] Due to the adoption of the above structure, the stove and the cooking pot of the integral meat-boiling boiler adopt a connected integral structure, which has low heat loss and high thermal efficiency; the air balancing plate is used to supplement air into the furnace to assist combustion, so that the fuel burns fully and exhaust gas pollution can be effectively reduced; the air supplemented by the air balancing plate flows in an orderly manner under the action of the induced draft fan and fully exchanges heat with the bottom of the cooking pot, thereby improving the thermal efficiency and evenly distributing the heat to the bottom of the pot, avoiding local overheating of the bottom of the pot, and preventing nodules from forming on the bottom of the pot, and the product quality is stable and reliable.

[0014] like Figure 1 、 Figure 2 As shown, the integrated meat-boiling boiler of the present invention comprises an open pot 1, constructed entirely of welded steel plates, offering excellent thermal conductivity. The pot 1 has a U-shaped cross-section, with an open top and a curved bottom. The front end of the pot 1 is provided with a front plate 11 and a rear plate 12. To enhance the heat exchange capacity of the pot bottom, the bottom of the pot 1 is provided with axially distributed fins 10. These fins 10 increase the surface area of the pot bottom and improve heat exchange efficiency.

[0015] The bottom of the open pot 1 is fixedly connected to the stove housing 2. The stove housing 2 is a rectangular frame formed by welding four vertical panels: front, rear, left, and right. The lower ends of the front and rear panels 11, 12 extend downward to form the front and rear ends of the stove housing 2, respectively. Of course, the front and rear ends of the stove housing 2 can also be welded to the front and rear panels 11, 12, respectively. The upper ends of the left and right vertical panels of the stove housing 2 are welded to the left and right sides of the open pot 1, respectively, so that the bottom of the open pot 1 is seamlessly connected to the upper end of the stove housing 2, forming a sealed space inside the stove housing 2, which can reduce heat loss.

[0016] The inner cavity of the stove shell 2 is provided with a furnace 3, an air distribution plate 4 and a return air duct 5. The furnace 3 is located in the middle below the open pot 1 and is a space enclosed by the air distribution plate 4 for placing fuel. The air distribution plate 4 is a hollow plate arranged around the furnace 3. It can be made of welded steel plates, or it can be made of refractory bricks or integrally formed of refractory materials. The side wall of the air distribution plate 4 facing the furnace 3 has a plurality of evenly distributed ventilation holes 41. If there is a certain gap between the upper end of the air distribution plate 4 and the bottom of the open pot 1, ventilation holes can also be provided at the upper end of the air distribution plate 4. The air distribution plate 4 in this embodiment is a long strip profile with a rectangular cross-section. Two air distribution plates 4 are symmetrically arranged on the left and right sides of the furnace 3, and the front end of the air distribution plate 4 is connected to the front plate of the stove shell 2 and the rear end is connected to the rear plate of the stove shell 2. The blower 7 is connected to the inner cavity of the air distribution plate 4 through a pipe. The blower 7 can be connected to the front end of the air distribution plate 4 or to its rear end. When in operation, the blower 7 blows air into the air distribution plate 4 and then into the furnace 3 through the ventilation holes 41, oxygenating the burning fuel and promoting combustion, thereby ensuring more complete combustion and reducing exhaust pollution. The return air duct 5 is a U-shaped duct that is tightly attached to the bottom of the open pot 1. One end of the return air duct 5 is connected to the rear end of the furnace 3 and the other end is connected to the exhaust pipe 6. The front end of the furnace 3 has a furnace door 31 mounted on the front end plate 11 at the front end of the stove housing 2 for adding fuel to the furnace.

[0017] The structure of the return air duct 5 can be various, such as Figure 1 、 Figure 2 In this embodiment, a uniform air plate 4 is positioned on each side of the furnace 3, parallel to the axis of the open pot 1. A partition 42 is positioned between the upper end of the uniform air plate 4 and the bottom of the open pot 1. The lower end of the partition 42 is connected to the upper end of the uniform air plate 4, and the upper end of the partition 42 abuts the bottom of the open pot 1 or is directly welded to the open pot 1. In this way, the uniform air plate 4 and the partition 42 form a single unit, enclosing the furnace space between the two partitions 42 and isolating the space inside and outside the partitions 42. The enclosed space between the outer sides of the partitions 42 and the left or right vertical plate of the stove housing 2 constitutes the return air duct 5. The upper end of the furnace 3 directly contacts the bottom of the open pot 1, allowing the flame and high-temperature exhaust gas in the furnace 3 to contact and heat the bottom of the open pot 1. The upper end of the return air duct 5 also directly contacts the bottom of the open pot 1, allowing the high-temperature exhaust gas in the return air duct 5 to contact and exchange heat with the bottom of the open pot 1.

[0018] like Figure 3As shown, as another embodiment of the structure of the return air duct 5, when the height of the air uniform plate 4 is such that its upper end is sufficient to contact the bottom of the open pot 1, the air uniform plate 4 itself can play the role of separating the inner and outer spaces. At this time, the space between the two air uniform plates 4 forms the furnace 3, and the enclosed space between the outer side of the air uniform plate 4 and the left vertical plate or the right vertical plate of the stove shell 2 is the return air duct 5.

[0019] like Figure 4 As shown, when the height of the air uniform plate 4 is insufficient for the upper end to contact the bottom of the open pot 1, there is a certain gap between the upper end of the air uniform plate 4 and the bottom of the open pot 1. In this case, a partition 42 can be provided on the outside of each air uniform plate 4. The upper end of the partition 42 contacts the bottom of the open pot 1 and the lower end is connected to the bottom plate of the stove shell 2, thereby separating the inner and outer spaces. In this way, the enclosed space between the partition 42 and the left or right vertical plate of the stove shell 2 is the return air duct 5.

[0020] like Figure 1 、 Figure 2 In the described embodiment, the rear end of the stove shell 2 is provided with a return air bin 8 connecting the furnace 3 and the return air duct 5. The return air bin 8 is a chamber welded on the rear end plate 12, and its cross-section can be rectangular or circular. The area covered by the return air bin 8 on the rear end plate 12 is sufficient to cover the rear end of the furnace 3 and the rear end of the return air duct 5. Furnace ventilation holes 13 and air duct ventilation holes 14 are provided on the rear end plate 12 at positions corresponding to the return air bin 8, wherein the furnace ventilation holes 13 are located at the rear end of the furnace 3, and the air duct ventilation holes 14 are located at the rear end of the return air duct 5. The exhaust gas generated by the combustion of fuel in the furnace 3 can pass through the furnace ventilation holes 13 into the return air bin 8, and then pass through the air duct ventilation holes 14 from the return air bin 8 into the return air duct 5. The front end of the stove shell 2 is provided with a smoke exhaust bin 9 that connects the return air duct 5 and the smoke exhaust pipe 6. The smoke exhaust pipe 6 is equipped with an induced draft fan 15. When the induced draft fan 15 is in operation, it creates a negative pressure in the smoke exhaust pipe 6 and the smoke exhaust bin 9, sucking the exhaust gas from the furnace and promoting the orderly flow of the exhaust gas, which is finally discharged through the smoke exhaust pipe 6. The smoke exhaust bin 9 is a chamber welded to the front end plate 11. The area covered by the front end plate 11 is sufficient to cover the front ends of the left and right return air ducts 5. The front end plate 11 covered by the smoke exhaust bin 9 has a smoke bin vent. The inner end of the smoke bin vent is connected to the return air duct 5, and the outer end is connected to the smoke exhaust bin 9. In this way, the exhaust gas in the left and right return air ducts 5 passes through the smoke bin vent and is concentrated in the smoke exhaust bin 9, and is finally discharged through the smoke exhaust pipe 6.

[0021] During use, the furnace door 31 is opened to add fuel to the furnace, and the blower 7 and induced draft fan 15 are turned on. The blower 7 blows air into the inner cavity of the air uniform plate 4, and then blows air into the furnace through the ventilation holes 41 on the air uniform plate 4 to assist combustion. Under the suction of the induced draft fan 15, the exhaust gas produced by the fuel combustion moves from front to back, and the flame and high-temperature airflow pass over the bottom of the open pot 1, heating the open pot 1. The flame heating area is large and dispersed, which can effectively avoid the phenomenon of pot bottom ablation and nodule formation caused by localized concentrated heating. At the same time, it can ensure that the pot body is heated evenly, avoiding the phenomenon of undercooked or undercooked products. The exhaust gas reaching the rear end of the furnace 3 still has a relatively high temperature. After being guided into the return air duct 5 by the return air bin 8, it flows from the rear end to the front end. During this process, the high-temperature exhaust gas passes over the bottom of the open pot 1 again, exchanging heat with the bottom of the pot, and fully absorbing the remaining heat in the exhaust gas. The temperature of the exhaust gas that finally reaches the front end of the return air duct 5 has been greatly reduced, and finally the low-temperature exhaust gas is discharged from the exhaust pipe 6, which has less pollution. Of course, in order to further reduce the exhaust gas pollution, a cyclone dust collector 16 can be connected to the rear end of the exhaust pipe 6 to further reduce the particulate pollutants in the exhaust gas. Figure 3 、 Figure 4 The working principle of the embodiment is the same as above and will not be described again here.
