Abstract
Description
Technical Field
[0001] The utility model discloses a biscuit baking smoke exhaust backflow prevention device, belonging to the technical field of food production and processing equipment. Background Art
[0002] In the production process of biscuits, baking is a key process. Baking is generally carried out in a baking oven, and the performance of the baking oven will directly affect the quality and production efficiency of the baked biscuits. Since the baking oven is relatively long (the total length is generally around 60 meters), the tunnel oven in the existing biscuit processing equipment must be equipped with a smoke exhaust duct at each interval to discharge the hot steam in the oven and reduce the moisture content of the biscuits when they are out of the oven.
[0003] At present, the exhaust duct of the baking furnace in the existing biscuit processing equipment is generally L-shaped. The hot steam generated during the baking process of biscuits contains a large amount of oil smoke. When the oil smoke is discharged through the exhaust duct, it is easy to re-liquefy and condense at the elbows and the rear section of the duct. This part of the oil will flow back into the baking furnace through the exhaust duct, polluting the production environment and even the product.
[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0007] By adopting the above technical scheme, when the smoke exhaust pipe discharges the oil smoke, the oil smoke enters from the air inlet end of the smoke exhaust pipe, passes through the center of the three blocking rings when passing through the elbow of the smoke exhaust pipe, and is finally discharged from the air outlet end of the smoke exhaust pipe. The truncated cone-shaped structure with the center of the blocking ring running through it and the design of the end with a smaller diameter facing the smoke exhaust pipe enable the oil smoke to flow back after liquefaction and condensation, and the side wall of the blocking ring can effectively block the dirty oil. The three blocking rings are respectively arranged at the two ends and the middle part of the elbow of the smoke exhaust pipe, which can fully block the dirty oil, further improve the anti-backflow effect and ensure the production quality. The three blocking rings are inclined so that the blocked dirty oil can flow and converge to the lower end of the blocking ring under the action of gravity, and then flow into the collection box through the oil discharge pipe, avoiding excessive overflow of the backflow dirty oil from the blocking ring. The setting of the ball valve can conveniently release the dirty oil collected in the collection box and clean it, thereby improving the convenience of using the device.

[0009] By adopting the above technical scheme and setting up a cleaning mechanism, the water source is sprayed out from three spray pipes after the water distribution pipe is connected to the water source, and the three spray pipes correspond to the positions of three blocking rings respectively. When the water source is sprayed out from the spray pipe, the water source is sprayed on the high end of the blocking ring on the side that blocks the oil stains, so that the water source can flow along the circumferential surface of the blocking ring to the low end, and the blocking ring is fully cleaned. The cleaned water source flows into the collection box along the oil discharge pipe, which prevents the cleaning water source from flowing back along the smoke exhaust pipe to the production equipment, and at the same time improves the convenience of cleaning the blocking ring.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0027] A biscuit baking smoke exhaust backflow prevention device, such as Figure 1-Figure 2 As shown, it includes an L-shaped smoke exhaust pipe 1, and a blocking mechanism is arranged at the elbow in the smoke exhaust pipe 1. The blocking mechanism includes three blocking rings 2, and the three blocking rings 2 are respectively arranged at both ends and the middle of the elbow. The blocking ring 2 is a truncated cone structure with a central penetration, and the ends of the three blocking rings 2 with smaller diameters are all facing the end of the smoke exhaust pipe 1 where air is discharged. When the smoke exhaust pipe 1 discharges the oil smoke, the oil smoke enters from the air inlet end of the smoke exhaust pipe 1, passes through the center of the three blocking rings 2 when passing through the elbow of the smoke exhaust pipe 1, and is finally discharged from the air outlet end of the smoke exhaust pipe 1. The truncated cone structure with a central penetration and the design of the end with a smaller diameter facing the smoke exhaust pipe 1 make it possible for the oil smoke to effectively block the dirty oil through the side walls of the blocking ring 2 when it flows back after liquefaction and condensation, and the three blocking rings 2 are respectively arranged on the two ends of the elbow of the smoke exhaust pipe 1 The design of the end and the middle part can fully block the dirty oil, further improve the anti-backflow effect and ensure the production quality. The three blocking rings 2 are all tilted, and a collecting mechanism is arranged on the outside of the smoke exhaust pipe 1, and the collecting mechanism is arranged on one side of the lower end of the blocking ring 2. The collecting mechanism includes a collecting box 3 and a ball valve 4. The collecting box 3 is arranged at the elbow of the smoke exhaust pipe 1, and the smoke exhaust pipe 1 is provided with a plurality of oil discharge pipes 5 connected with the collecting box 3. The ball valve 4 is arranged at the lower end of the collecting box 3. The three blocking rings 2 are tilted so that the blocked dirty oil can flow and converge to the lower end of the blocking ring 2 under the action of gravity, and then flow into the collecting box 3 through the oil discharge pipe 5, so as to avoid excessive backflow of dirty oil from overflowing from the blocking ring 2, and the setting of the ball valve 4 can conveniently release the dirty oil collected in the collecting box 3 and clean it, thereby improving the convenience of using the device.
[0028] The smoke exhaust pipe 1 is provided with a cleaning mechanism, which is arranged at the elbow and located on the high end side of the blocking ring 2. The cleaning mechanism includes a water distribution pipe 6 and three spray pipes 7. The water distribution pipe 6 is arranged at the elbow of the smoke exhaust pipe 1. The three spray pipes 7 are arranged on the water distribution pipe 6 and one end is connected with the water distribution pipe 6 and the other end extends into the smoke exhaust pipe 1. The positions of the three spray pipes 7 correspond to the positions of the three blocking rings 2. One end of the three spray pipes 7 extending into the smoke exhaust pipe 1 is respectively located on one side of the high end of the three blocking rings 2 and is located at a smaller diameter of the blocking ring 2. On the other hand, through the setting of the cleaning mechanism, the water distribution pipe 6 is connected to the water source and the water is sprayed out from the three spray pipes 7, and the three spray pipes 7 correspond to the positions of the three blocking rings 2 respectively. When the spray pipe 7 sprays the water source, the water source is sprayed on the high end of the blocking ring 2 on the side that blocks the oil stains, so that the water source can flow to the low end along the circumference of the blocking ring 2, and the blocking ring 2 is fully cleaned. The cleaned water source flows into the collecting box 3 along the oil discharge pipe 5, which prevents the cleaning water source from flowing back to the production equipment along the smoke exhaust pipe 1, and at the same time improves the convenience of cleaning the blocking ring 2.
[0029] The water distribution pipe 6 is connected to the water inlet pipe 8, and the water distribution pipe 6 is connected to the water pump through the water inlet pipe 8. The water inlet pipe 8 is provided with a solenoid valve 9. Through the setting of the water inlet pipe 8 and the solenoid valve 9, the operation of the cleaning mechanism can be accurately controlled to improve the overall safety and reliability. The three spray pipes 7 are provided with spray heads at one end extending into the smoke exhaust pipe 1. Through the setting of the spray heads, the coverage area of the water source sprayed by the spray pipe 7 can be effectively increased, and its cleaning efficiency can be improved. A blocking net 10 is provided at one end of the smoke exhaust pipe 1. By setting the blocking net 10 at the air outlet end of the smoke exhaust pipe 1, it can effectively prevent debris from clogging the smoke exhaust pipe 1, ensure the smooth flow of the smoke exhaust pipe 1, and facilitate its long-term stable operation. The three blocking rings 2 are all made of stainless steel. The use of stainless steel blocking rings 2 increases the corrosion resistance and durability of the device and extends its service life.
[0030] When the smoke exhaust pipe 1 generates dirty oil backflow during use, the dirty oil flows downward toward the processing equipment under the influence of gravity at the elbow of the smoke exhaust pipe 1. At this time, the blocking ring 2 can block the dirty oil to prevent the dirty oil from flowing further downward. After being blocked by the blocking ring 2, the dirty oil flows toward the lower end of the blocking ring 2 along the inclined structure of the blocking ring 2 under the influence of gravity, thereby flowing into the oil exhaust pipe 5 on the smoke exhaust pipe 1, and finally flows into the collecting box 3, thereby effectively collecting the dirty oil and preventing the dirty oil from flowing back, ensuring the cleanliness of production and processing and improving the production quality. When it is necessary to clean the blocking ring 2, by starting the solenoid valve 9, the water pumped out by the water pump is output to the spray pipe 7 through the water inlet pipe 8 and the water distribution pipe 6, and is sprayed through the spray head on the spray pipe 7, the blocking ring 2 can be cleaned, and the cleaned water can flow into the collecting box 3 along the blocking ring 2, while ensuring the cleaning quality and improving the convenience of cleaning.
