Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a high-temperature smoke extraction and retention fan device for fire protection. Background Technology

[0002] In the event of a fire, timely and effective removal of dense smoke is crucial for protecting lives and minimizing property damage. Therefore, smoke extraction fans are typically installed in fire escape routes to ensure proper smoke removal. However, traditional fire smoke extraction fans have the following problems:

[0003] Firstly, during the smoke exhaust process, the temperature of the dense smoke is high, which can adversely affect the performance of the fan when it comes into contact with it. For example, components such as the impeller may deform due to high temperature, thereby reducing the smoke exhaust efficiency.

[0004] Secondly, most existing smoke exhaust fans do not have an effective retention function and cannot effectively intercept harmful substances in the smoke (such as dust, toxic gas particles, etc.), which can easily cause secondary pollution. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1, referring to Figure 1-5 A high-temperature smoke extraction and retention fan device for fire fighting includes a support base 1 and a cooling mechanism;

[0030] In this embodiment, the support base 1 is fixedly connected to the wall by fasteners, and a smoke exhaust pipe 2 is fixedly connected through the support base 1. A smoke exhaust fan 3 is fixedly installed at one end of the smoke exhaust pipe 2.

[0031] In this embodiment, the cooling mechanism includes a water tank 4 fixedly connected to the top outer wall of the support base 1, a serpentine heat-conducting copper pipe 5 disposed in the water tank 4, a cooler 6 and a temperature sensor 7 fixedly installed on one side inner wall of the water tank 4, an agitation assembly, and a controller 8 fixedly installed on the front outer wall of the water tank 4.

[0032] Furthermore, the temperature sensor 7 and the cooler 6 are electrically connected to the controller 8, and the top of the water tank 4 is provided with a filling pipe, the top of which is threaded with a cap.

[0033] Furthermore, the top end of the serpentine heat-conducting copper pipe 5 penetrates the top of the water storage tank 4 and is sealed and fixedly connected to the water storage tank 4 through the first sealing element, the bottom end of the serpentine heat-conducting copper pipe 5 penetrates the lower part of one side of the water storage tank 4 and is sealed and fixedly connected to the water storage tank 4 through the second sealing element, and the bottom end of the serpentine heat-conducting copper pipe 5 is sealed and fixedly connected to the exhaust pipe 2.

[0034] Furthermore, the agitation assembly includes two agitator shafts 9 that are connected to the inner wall of the top of the water tank 4 through two sealed bearings, two spiral agitator blades 10 welded to the outer wall of the two agitator shafts 9, a support cover 11 fixedly connected to the outer wall of the top of the water tank 4, a drive motor 12 fixedly installed on the outer wall of the center of the top of the support cover 11, a drive gear 13 fixedly mounted on the output shaft of the drive motor 12, and two transmission gears 14 fixedly mounted on the top of the two agitator shafts 9 in sequence.

[0035] Furthermore, both spiral stirring blades 10 are located inside the water storage tank 4, and the spiral directions of the two spiral stirring blades 10 are opposite. The output shaft of the drive motor 12 passes through the top center of the support cover 11, and the drive gear 13 is located between the two transmission gears 14. Both transmission gears 14 mesh with the drive gear 13.

[0036] In this embodiment, the process is as follows: First, when high-temperature smoke flows into the serpentine heat-conducting copper pipe 5, the high-temperature heat is introduced into the cold water source in the water storage tank 4 by the serpentine heat-conducting copper pipe 5. The temperature sensor 7 detects the water temperature in the water storage tank 4 in real time and transmits the temperature signal to the controller 8. The controller 8 controls the cooler 6 to work to continuously ensure the cooling temperature of the cold water source. Second, the drive motor 12 drives the drive gear 13 to rotate. Subsequently, the two transmission gears 14 meshing with the drive gear 13 drive the two spiral stirring blades 10 on the two stirring shafts 9 to rotate together. Through the rotation effect of the two spiral stirring blades 10 with opposite spiral directions, the cold water source in the water storage tank 4 can be fully stirred to accelerate its flow rate, thereby helping to improve the cooling rate of the cold water source on the serpentine heat-conducting copper pipe 5. This facilitates the full cooling of high-temperature smoke during the smoke exhaust process, avoids the adverse effects of high temperature on the performance of the fan, and helps to ensure the smoke exhaust efficiency.

[0037] Example 2, refer to Figure 1-2 and Figure 6 This embodiment is an optimization based on embodiment 1. Specifically, it is: a high-temperature smoke extraction and retention fan device for fire protection, which also includes a smoke extraction mechanism. The smoke extraction mechanism includes a fixed cover 15 fixedly connected to the outer wall of the other side of the water storage tank 4, a rotating pipe 16 rotatably mounted on the fixed cover 15, a smoke extraction hood 17 fixedly connected to the lower end of the rotating pipe 16, a rotation drive assembly, and a retention and filtration assembly.

[0038] Furthermore, the filter assembly includes a coarse filter 22, an activated carbon filter 23, and a high-efficiency filter 24, which are sequentially fixed and installed inside the smoke hood 17. The coarse filter 22 is made of stainless steel wire and is used to intercept larger dust particles and debris. The activated carbon filter 23 can adsorb some of the toxic gases in the smoke. The high-efficiency filter 24 is made of glass fiber and can filter out tiny dust and harmful particles, ensuring that the exhaust smoke is relatively clean. In this way, the exhaust fan 3 has an effective retention function and can effectively intercept harmful substances in the smoke, avoiding secondary pollution.

[0039] Furthermore, the rotary drive assembly includes a servo motor 18 connected to the inner wall of the fixed cover 15 via a motor mount, a drive bevel gear 19 fixedly mounted on the output shaft of the servo motor 18, and a driven bevel gear 20 fixedly mounted on the rotary tube 16. The drive bevel gear 19 and the driven bevel gear 20 mesh with each other, and the smoke hood 17 can be controlled to reciprocate within a range of 120 degrees by an encoder outside the servo motor 18.

[0040] Furthermore, a rotary joint 21 is provided above the fixed cover 15, the top end of the rotary tube 16 is sealed and fixedly connected to the rotating end of the rotary joint 21, and the top end of the serpentine heat-conducting copper tube 5 is sealed and fixedly connected to the fixed end of the rotary joint 21.

[0041] In this embodiment, the servo motor 18 drives the active bevel gear 19 to rotate, and the driven bevel gear 20 meshing with the active bevel gear 19 drives the rotating tube 16 to rotate. As a result, the smoke hood 17 connected to the lower end of the rotating tube 16 swings back and forth, thereby effectively expanding the smoke range and improving the smoke exhaust efficiency of the entire smoke exhaust fan 3.

[0042] Working principle: First, fix the support 1 to the wall, pre-embed the smoke exhaust pipe 2 into the wall hole and make the smoke exhaust fan 3 connected to the outside. Then start the smoke exhaust fan 3 to start the smoke exhaust work. The smoke will pass through layers of the filter components in the smoke hood 17 to ensure that the smoke discharged later is relatively clean.

[0043] Secondly, the servo motor 18 drives the active bevel gear 19 to rotate, and then the driven bevel gear 20 meshing with the active bevel gear 19 will drive the rotating tube 16 to rotate. As a result, the smoke hood 17 connected to the lower end of the rotating tube 16 will swing back and forth, thereby effectively expanding the smoke range and improving the smoke exhaust efficiency of the entire smoke exhaust fan 3.

[0044] Finally, the smoke drawn in from the fume hood 17 passes through the rotating pipe 16 and the rotating joint 21 and enters the serpentine heat-conducting copper pipe 5, and is finally discharged from the exhaust pipe 2. During this process, when the high-temperature smoke flows into the serpentine heat-conducting copper pipe 5, the high-temperature heat is introduced into the cold water source in the water storage tank 4 by the serpentine heat-conducting copper pipe 5. The temperature sensor 7 detects the water temperature in the water storage tank 4 in real time and transmits the temperature signal to the controller 8. The controller 8 controls the cooler 6 to work to continuously ensure the cooling temperature of the cold water source. The stirring component can also fully stir the cold water source in the water storage tank 4 to accelerate its flow rate, thereby helping to improve the cooling rate of the cold water source on the serpentine heat-conducting copper pipe 5. This facilitates the full cooling of the high-temperature smoke during the exhaust process, avoids the adverse effects of high temperature on the performance of the fan, and helps to ensure exhaust efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
