Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat recovery ventilation for cosmetic workshops, in particular to a heat recovery ventilation device for cosmetic workshops. BACKGROUND

[0002] Cosmetic workshops have strict requirements on temperature and humidity, and the air conditioning system needs to be continuously operated to maintain a stable environment, which consumes a high proportion of energy. Therefore, a heat recovery ventilation system becomes a key energy-saving configuration. The core of the system is to recover the energy in the workshop exhaust air (including cold or heat) through a heat exchange device, and then send the pre-processed fresh air into the workshop to reduce the air conditioning load.

[0003] The patent application with publication number CN1987225A discloses a heat exchange heater structure of a waste heat recovery type ventilation device. In order to perform heat exchange, the waste heat recovery type ventilation device using a heater is composed of: a plurality of thin pin tubes bent in a "U" shape and having their two sides extended to form openings on the extended sides, thereby being capable of storing refrigerant; a curved semi-ring-shaped tube connected to the end of the opening of the thin pin tube and guiding the flow of refrigerant inside the thin pin tube; and a plurality of heat absorption pins and heat release pins inserted at a predetermined interval and connected together through the thin pin tube to form a plate shape, thereby being capable of promoting heat absorption and heat release. The present application composed as described above has the advantage of reducing production processes.

[0004] In a cosmetic production workshop, in order to ensure product quality and the comfort of the production environment, a ventilation system is usually required to introduce fresh air and exhaust waste gas. In the prior art, a simple ventilation device has only one function, which can only exchange indoor and outdoor air. When the weather conditions are bad, such as cold outdoor in winter or hot outdoor in summer, directly introducing untreated outdoor air will cause significant temperature fluctuations in the workshop. In order to maintain a constant temperature environment, the heating or cooling system will bear additional load, resulting in huge energy consumption. In particular, the process equipment (such as reaction kettles and sterilization equipment) in the cosmetic workshop will continuously emit high-temperature waste gas. The heat energy contained in this part of waste gas is usually directly discharged into the atmosphere without any recovery, resulting in a waste of energy.

[0005] Therefore, one of the outstanding problems in the prior art is that the traditional workshop ventilation device has only one function and cannot effectively recover and utilize the heat energy in the waste gas emitted by the workshop process. At the same time, when ventilation is performed under extreme weather conditions, it will increase the energy load of the workshop temperature control system, resulting in high overall energy consumption. The lack of this energy recovery link not only increases the production and operation cost, but also does not conform to the current trend of green manufacturing and energy saving and emission reduction. SUMMARY

[0006] In view of the deficiencies of the prior art, the present application provides a heat recovery air exchange device for a cosmetic workshop to solve the problems raised in the above background art.

[0016] Preferably, the other end of the first pipeline is fixedly connected with a first fan, and a first support is fixedly connected between the first fan and the frame.

[0017] Preferably, the other end of the second pipeline is fixedly connected with the end of the gas conveying pipe.

[0018] Preferably, the outer wall of the gas conveying pipe is fixedly connected with a limiting assembly.

[0019] Preferably, the limiting assembly comprises a limiting bin fixedly connected with the outer wall of the gas conveying pipe, and the limiting assembly adopts a spring and baffle structure, which automatically pushes open the baffle when the high-temperature waste gas flows, allows the gas to pass through in one direction, and resets the baffle by the spring when the gas flow stops, preventing the backflow of the gas, ensuring the directionality of the waste gas emission, improving the reliability and safety of the system, and avoiding energy loss or cross contamination.

[0020] Preferably, the inner wall of the limiting bin is fixedly connected with a bearing, the outer wall of the bearing is rotatably connected with a baffle, and the baffle is fixedly connected with the spring between the inner wall of the limiting bin.

[0021] Preferably, the outer wall of the frame is fixedly connected with a fresh air mechanism.

[0022] Preferably, the fresh air mechanism comprises a horizontal bin, the fresh air mechanism is combined with a water tank and water-absorbing cotton, when the second fan works, the outdoor air sucked carries moisture when flowing through the water-absorbing cotton, thereby entering the indoor after humidification, which helps to reduce the indoor temperature and improve the humidity under hot and dry conditions, improves the comfort of the workshop environment, the water tank can be conveniently replenished with water or cleaned through the pull-out plate, the horizontal bin is fixedly connected with a second support between the frame, the end of the horizontal bin is fixedly connected with the second fan, the outer wall of the horizontal bin is fixedly connected with the water tank, the top of the water tank is inserted with the pull-out plate, the inner wall of the horizontal bin is fixedly connected with a third support, the outer wall of the third support is fixedly connected with the water-absorbing cotton, and the water-absorbing cotton extends into the interior of the water tank.

[0023] The application provides a heat recovery ventilation device for a cosmetic workshop.

[0024] 1. The heat recovery ventilation device for the cosmetic workshop, by the design of the heat exchange mechanism, the high-temperature waste gas discharged from the cosmetic workshop is used to heat the heat exchange box, when it is cold outdoors, the cold air introduced by the suction machine absorbs heat when flowing through the outer wall of the heat exchange box, thereby preheating and then entering the indoor, reducing the energy consumption required for additional heating; when it is hot outdoors, the suction machine works reversely, discharges the indoor hot air, and the hot air carries heat when flowing through the outer wall of the heat exchange box, thereby being discharged outdoors, realizing the effective recovery and utilization of heat, and improving the energy utilization efficiency.

[0025] 2. The cosmetic workshop uses a heat recovery ventilation device. The suction machine in the ventilation mechanism can adjust its rotation to be forward or reverse according to changes in ambient temperature. Fresh air is introduced from the outside when it is cold, and stale hot air is discharged from the inside when it is hot. This achieves flexible exchange of indoor and outdoor gases, adapts to different seasonal climate conditions, and ensures air circulation in the workshop.

[0026] 3. The cosmetic workshop uses a heat recovery ventilation device. Through the built-in filter plate, it can effectively filter particulate matter, dust and other impurities in the air, ensuring that the air entering the room is clean and meeting the strict air quality standards of cosmetic production workshops, reducing the risk of product contamination. At the same time, the filter plate can be easily viewed and replaced through the second door panel, making maintenance simple.

[0027] 4. The cosmetic workshop uses a heat recovery ventilation device. The first and second door panels on the frame are located near the suction machine and filter plate, respectively. This facilitates daily inspection of the suction machine's working status and replacement of the filter plate without disassembling the entire device, simplifying the maintenance process and reducing maintenance time and labor costs.

[0028] 5. The cosmetic workshop uses a heat recovery ventilation device. The fresh air system uses a combination of a water tank and absorbent cotton. When the second fan is working, the outdoor air drawn in carries moisture as it flows through the absorbent cotton, thus humidifying it before entering the room. Under hot and dry conditions, this helps to reduce the indoor temperature and increase the humidity, improving the comfort of the workshop environment. At the same time, the water tank can be easily replenished or cleaned through a pull-out panel.

[0029] 6. The heat recovery ventilation device used in this cosmetic workshop adopts a spring and baffle structure through the limiting component. When the high-temperature exhaust gas flows, the baffle is automatically opened to allow the gas to pass in one direction. When the airflow stops, the spring drives the baffle to reset, preventing the gas from flowing back. This ensures the directionality of exhaust gas emission, improves the reliability and safety of the system, and avoids energy loss or cross-contamination. Attached Figure Description

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0042] Example 1, please refer to Figures 1-7 The present invention provides a technical solution: a heat recovery ventilation device for cosmetic workshops, including a frame 1, an installation plate 2 fixedly connected to the outer wall of the frame 1, and a ventilation mechanism 3 fixedly connected to the outer wall of the frame 1.

[0043] Holes for this device are made in the wall, as shown in the attached diagram. Figure 1 As shown, mounting plate 2 is set into two sets, which are installed inside and outside the wall at the location of the wall hole, respectively;

[0044] The ventilation mechanism 3 includes:

[0045] The suction machine 31 is fixedly connected to the side of the frame 1;

[0046] The first air inlet 32 ​​is opened on the outer wall of the frame 1, and the second air inlet 33 is opened on the outer wall of the frame 1 at the opposite position of the mounting plate 2.

[0047] The first door panel 35 is rotatably connected to the outer wall of the frame 1 at a position adjacent to the side where the suction machine 31 is located;

[0048] The second door panel 36 is rotatably connected to the outer wall of the frame 1 on the other side of the suction machine 31.

[0049] Filter plate 34 is fixedly connected to the inner wall of frame 1;

[0050] With the mounting plate 2 installed, half of the frame 1 is inside the wall and half is outside the wall, so that the first air inlet 32 ​​is inside the wall and the second air inlet 33 is outside the wall.

[0051] A heat exchange mechanism 4 is fixedly connected to the inner wall of frame 1.

[0052] The heat exchange mechanism 4 includes a heat exchange box 43, which is fixedly connected to the inner wall of the frame 1 between the suction machine 31 and the filter plate 34. One end of the second pipe 45 is fixedly connected to the top of the heat exchange box 43, and one end of the first pipe 44 is fixedly connected to the bottom of the heat exchange box 43.

[0053] The other end of the first pipe 44 is fixedly connected to the first fan 41, and the first fan 41 is fixedly connected to the frame 1 by the first bracket 42.

[0054] The other end of the second pipe 45 is fixedly connected to the end of the gas transmission pipe 46.

[0055] A limit assembly 47 is fixedly connected to the outer wall of the gas pipeline 46.

[0056] The limiting component 47 includes a limiting chamber 471, which is fixedly connected to the outer wall of the gas supply pipe 46.

[0057] A bearing 473 is fixedly connected to the inner wall of the limiting chamber 471, and a baffle 474 is rotatably connected to the outer wall of the bearing 473. A spring 472 is fixedly connected between the baffle 474 and the inner wall of the limiting chamber 471.

[0058] When it is cold outdoors, the suction machine 31 is powered on and starts. The suction machine 31 draws in cold air from the outside through the second air outlet 33. After being filtered by the filter plate 34 in the frame 1, it is delivered to the room through the first air outlet 32. The working status of the suction machine 31 in the frame 1 can be viewed by opening the first door panel 35, and the filter plate 34 can be viewed and replaced by opening the second door panel 36.

[0059] The first fan 41 is connected to the high-temperature exhaust gas discharged from the cosmetic workshop. The first fan 41 delivers the exhaust gas to the heat exchange box 43 through the first pipe 44. The heat exchange box 43 is made of temperature-sensitive material. When the high-temperature exhaust gas passes through the heat exchange box 43, the temperature of the heat exchange box 43 will rise. After passing through the heat exchange box 43, the exhaust gas is discharged to the outside through the second pipe 45 and the gas delivery pipe 46. When the airflow passes through the limiting component 47, the airflow will push open the baffle 474. When the airflow stops, the elasticity of the spring 472 drives the baffle 474 to rotate and reset, thereby restricting the unidirectional flow of the high-temperature exhaust gas.

[0060] There is a gap between the outer wall of the heat exchange box 43 and the inner wall of the frame 1. When the suction machine 31 draws in the outdoor air, the airflow carries the heat generated by the heat exchange box 43 into the room.

[0061] Example 2, please refer to Figures 1-9 Based on Embodiment 1, the present invention provides a technical solution:

[0062] A fresh air system 5 is fixedly connected to the outer wall of frame 1.

[0063] The fresh air mechanism 5 includes a horizontal chamber 51, a second bracket 52 is fixedly connected between the horizontal chamber 51 and the frame 1, a second fan 57 is fixedly connected to the end of the horizontal chamber 51, a water tank 53 is fixedly connected to the outer wall of the horizontal chamber 51, a pull-out plate 54 is inserted into the top of the water tank 53, a third bracket 56 is fixedly connected to the inner wall of the horizontal chamber 51, and absorbent cotton 55 is fixedly connected to the outer wall of the third bracket 56, with the absorbent cotton 55 extending into the interior of the water tank 53.

[0064] When it is hot outdoors, the suction machine 31 is powered on and rotates in reverse, thereby drawing in indoor air through the first air outlet 32 ​​and then expelling it outdoors through the second air outlet 33, thus guiding the hot air out of the room.

[0065] The first fan 41 is connected to the high-temperature exhaust gas discharged from the cosmetic workshop. The first fan 41 delivers the exhaust gas to the heat exchange box 43 through the first pipe 44. The heat exchange box 43 is made of temperature-sensitive material. When the high-temperature exhaust gas passes through the heat exchange box 43, the temperature of the heat exchange box 43 will rise. After passing through the heat exchange box 43, the exhaust gas is discharged to the outside through the second pipe 45 and the gas delivery pipe 46. When the airflow passes through the limiting component 47, the airflow will push open the baffle 474. When the airflow stops, the elasticity of the spring 472 drives the baffle 474 to rotate and reset, thereby restricting the unidirectional flow of the high-temperature exhaust gas.

[0066] There is a gap between the outer wall of the heat exchange box 43 and the inner wall of the frame 1. When the suction machine 31 draws the gas in the room and passes through the frame 1, the airflow will carry the heat generated by the heat exchange box 43 to the outside.

[0067] When it is hot outdoors, the second fan 57 is activated. The second fan 57 draws in outdoor air through the transverse chamber 51. The transverse chamber 51 is located away from the air supply pipe 46 and the second air supply port 33, thereby reducing the re-drawing of hot air. During the process of the second fan 57 drawing outside air into the room, an appropriate amount of water is pre-filled in the water tank 53. The water-absorbing cotton 55 absorbs the water in the water tank 53. When the airflow in the transverse chamber 51 passes through, it blows onto the water-absorbing cotton 55, carrying some of the moisture in the water-absorbing cotton 55 into the room, thus accelerating the cooling of the room.

[0068] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
