Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification equipment, in particular to a smoke exhaust purification mechanism. Background Art

[0002] Existing automatic catering vending equipment can be divided into two categories. The first category cannot completely avoid manual operation, and the second category can be completely unmanned. Both can complete the preparation of dishes. Among them, some equipment directly installs a smoke exhaust pipe next to the pot, and extracts air through a set of integrated smoke hoods. When multiple groups of pots work at the same time, they also extract air through the same smoke hood and then discharge it through a set of corrugated smoke pipes. Since automatic vending equipment often runs at a high frequency and has a large smoke exhaust load, on the one hand, the integrated smoke hood cannot meet the smoke exhaust effect, and on the other hand, it is easy to cause smoke pipe leakage, pollute the equipment, and have a high maintenance frequency.

[0003] Therefore, there is an urgent need for a fume exhaust purification mechanism that can effectively improve the fume emission effect, avoid fume leakage, and improve the operating stability of the overall equipment. Utility Model Content

[0032] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0033] refer to Figure 1-2 The specific embodiment of the present utility model provides a smoke exhaust purification mechanism, including:

[0034] Smoke collector 1, which is installed on the main frame;

[0035] Smoking units, wherein a plurality of smoking units are connected to the peripheral sides of the smoke collector 1;

[0036] The movable air cover 5 is slidably connected to the main frame. The air inlet of the movable air cover 5 is axially sleeved on the air outlet of the smoke collector 1. The inner radial dimension of the movable air cover 5 is larger than the inner diameter of the air outlet of the smoke collector 1.

[0037] The flue gas purification unit is connected to the air outlet of the movable air hood 5.

[0038] Existing automatic vending equipment installs a smoke exhaust pipe directly next to the pot, and exhausts air through a set of integrated smoke hoods. When multiple pots are working at the same time, the air is also extracted through the same smoke hood and then discharged through a set of corrugated smoke pipes. Since automatic vending equipment often operates at a high frequency and the smoke exhaust load is large, on the one hand, the integrated smoke hood cannot meet the smoke exhaust effect, and on the other hand, the oil fume pressure can easily cause the smoke pipe to leak, pollute the equipment, and increase the maintenance frequency. In this application, a smoke collector 1 is installed, and several smoking units are connected to the periphery of the smoke collector 1. Each smoking unit corresponds to a pot. This arrangement can effectively draw away all the generated oil smoke; at the same time, a movable air hood 5 is also provided. Its main function is to push the movable air hood 5 when the exhaust volume suddenly increases, thereby reducing the pressure of the entire exhaust pipe, which is beneficial to protecting the entire exhaust pipe. In addition, the internal radial dimension of the movable air hood 5 is larger than the inner diameter of the air outlet of the smoke collector 1. This arrangement allows the smoke discharged from the air outlet of the smoke collector 1 to suddenly enter a larger space, and the pressure of the smoke is instantly reduced, effectively reducing the damage to the movable air hood 5; the main function of the smoke purification unit is to purify oil smoke and reduce pollution. Overall, this application can effectively improve the oil smoke emission effect, avoid oil smoke leakage, and improve the operating stability of the overall equipment and reduce the maintenance frequency.

[0039] To further optimize the solution, the smoking unit includes:

[0040] The smoking hood 4 is installed on the main frame, and the bottom of the smoking hood 4 is set corresponding to the pot;

[0041] The axial flow fan 2 is installed between the top of the smoke hood 4 and the smoke collector 1.

[0042] The bottom smoking port of the smoking hood 4 corresponds to the pot. Under the suction effect of the axial flow fan 2, the oil smoke generated during the cooking process can be effectively sucked away to prevent the oil smoke from polluting the equipment.

[0043] Further optimization plans also include:

[0044] Check valve 3, check valve 3 is installed between axial flow fan 2 and smoke hood 4.

[0045] The main function of the check valve 3 is to prevent the oil smoke in the movable air hood 5 and the fume purification unit from returning to the fume hood 4.

[0046] Further optimization plans also include:

[0047] The sealing ring is located between the air outlet of the smoke collector 1 and the air inlet of the movable air hood 5. The sealing ring is sleeved around the air outlet of the smoke collector 1 and axially slides with the inner side of the air inlet of the movable air hood 5.

[0048] The main function of the sealing ring is to prevent smoke leakage at the connection when the air outlet of the smoke collector 1 and the air inlet of the movable air cover 5 slide relative to each other.

[0049] To further optimize the solution, the flue gas purification unit includes:

[0050] The plasma fume purifier 7 is installed on the main frame and is communicated with the air outlet of the movable wind hood 5.

[0051] The plasma flue gas purifier 7 can remove the smell of oil smoke in the flue gas in a long-term and durable manner, reducing air pollution.

[0052] Further optimization plans also include:

[0053] The connecting hose 6 is fixedly connected between the air outlet of the movable air hood 5 and the air inlet of the plasma fume purifier 7.

[0054] By adopting the connecting hose 6, the movable air hood 5 can remain smooth during the sliding process, and at the same time, the connection between the movable air hood 5 and the connecting hose 6 can be prevented from being disconnected; under the action of the oil smoke pressure, the movable air hood 5 slides in the direction away from the smoke collector 1, squeezing the connecting hose 6, and the connecting hose 6 undergoes elastic deformation; when the smoke exhaust stops, the oil smoke pressure disappears, and under the rebound action of the connecting hose 6, the movable air hood 5 returns to its original position.

[0055] Further optimization plans also include:

[0056] The exhaust port 8 is provided at the air outlet of the plasma fume purifier 7;

[0057] The induced draft fan 9 is installed between the plasma flue gas purifier 7 and the exhaust port 8.

[0058] Under the action of the induced draft fan 9, the exhaust speed of the oil smoke is effectively increased, so that the oil smoke quickly passes through the plasma fume purifier 7 and is discharged from the exhaust port 8.

[0059] Further optimization plans also include:

[0060] The track 10 is fixedly connected to the main frame, and the movable wind cover 5 is axially slidably connected to the track 10.

[0061] The main function of the track 10 is to facilitate the smooth sliding of the movable air hood 5 on the main frame.
