Abstract
Description
Technical Field
[0001] This utility model relates to an atomizing circulating spraying device. Background Technology
[0002] The production process of freeze-dried facial masks involves: immersing the wide membrane cloth in the base solution (completely soaking the membrane cloth in the solution) → drying the membrane cloth (to a semi-dry state to prevent the medicine from flowing out) → cutting the membrane cloth (cutting one wide membrane cloth into three narrow membrane cloths) → spraying the narrow membrane cloth with active ingredients → cutting the narrow membrane cloth into face shapes → freeze-drying the face-shaped facial mask in the freeze-drying room. Before the freeze-drying process, a small amount of active ingredients needs to be evenly sprayed onto the surface of the freeze-dried facial mask, and the amount of active ingredients attached cannot be too much. Currently, the methods of spraying active ingredients or immersing active ingredients into the surface of the mask are mostly used. However, the amount of active ingredients attached is not easy to control and is uneven. In addition, the volatilization and overflow of active ingredients are relatively serious, and the volatilization and overflow of active ingredients will pollute other infrastructure. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an atomizing circulating spraying device that can atomize active ingredients into tiny droplets, which are then guided by an atomizing circulating flow guiding mechanism to adhere in small quantities and evenly to the surface of a freeze-dried mask. The device also condenses and recovers any overflowing atomized active ingredient gas, which can significantly reduce the volatilization of active ingredients and the pollution of other infrastructure caused by overflowing active ingredients.
[0004] The technical solution to achieve the above objective is: an atomizing circulating spraying device, comprising a frame, a condensation and collection outer cavity, a membrane cloth guiding mechanism, and two sets of atomizing circulating guiding mechanisms, wherein:
[0005] The two sets of atomizing circulation guiding mechanisms are arranged on the frame, one on the left and one on the right.
[0006] Each atomizing circulation guiding mechanism includes an atomizing circulation inner cavity, a wall-mounted liquid return pipe, a vacuum guide device one, a vacuum guide device two, a condensate collection bottle one, a condensate collection bottle two, and four condensers. The atomizing circulation inner cavity is located inside the condensate collection outer cavity. The atomizing circulation inner cavity is composed of a circulating airflow buffer cavity, an atomizing cavity, and a return cavity connected sequentially from top to bottom, and there is a gap between the atomizing cavity and the return cavity for the membrane cloth to pass through. The four condensers are condenser one, condenser two, condenser three, and condenser four arranged sequentially from back to front. The cold water inlets and cold water outlets of condenser one, condenser two, condenser three, and condenser four are connected in series through pipes.
[0007] An atomizer is installed inside the atomizing chamber. The atomizing chamber is provided with an atomizer liquid inlet and an atomizer air inlet connected to the atomizer. A wall-mounted liquid collection tank is provided on the inner wall of the atomizing chamber. A liquid collection trough is provided at the bottom of the condensate collection outer chamber. One end of the wall-mounted liquid collection trough is connected to the wall-mounted liquid return pipe, and the other end of the wall-mounted liquid return pipe is connected to the liquid collection trough. The liquid collection trough is connected to the condensate collection bottle through a pipe.
[0008] The gas inlet of the first condenser is connected to the reflux chamber via a pipe; the gas outlet of the first condenser is connected to the suction end of the first vacuum guide; the blowing end of the first vacuum guide is connected to the circulating airflow buffer chamber; and the liquid outlet of the first condenser is connected to the second condensate collection bottle.
[0009] The gas inlets of condensers two, three, and four are connected to the condensate collection chamber via pipes; the gas outlets of condensers two, three, and four are connected to the suction end of vacuum guide valve two via pipes, and the blowing end of vacuum guide valve two is open to the outside atmosphere; the liquid outlets of condensers two, three, and four are connected to condensate collection bottle one via pipes.
[0010] The atomizing circulation cavities of the two sets of atomizing circulation guiding mechanisms are arranged adjacent to each other.
[0011] The membrane guide mechanism is mounted on the frame and is used to guide the membrane through the gap between the atomization chamber and the return chamber.
[0012] In the aforementioned atomizing circulating spraying device, a buffer mesh plate is provided between the circulating airflow buffer chamber and the atomizing chamber.
[0013] In the aforementioned atomizing circulating spraying device, an atomizer mounting bracket is vertically arranged inside the atomizing chamber, and the atomizer is adjustable up and down on the atomizer mounting bracket.
[0014] In the aforementioned atomizing circulating spraying device, the film guiding mechanism includes a plurality of film guiding rollers arranged in a Z-shape, and the film guiding rollers are mounted on the frame.
[0015] In the aforementioned atomizing circulating spraying device, the four condensers are fixed to the frame via condenser mounting brackets.
[0016] In the aforementioned atomizing circulating spraying device, an acrylic cover plate is provided at the top of the condensation collection outer cavity.
[0017] In the aforementioned atomizing circulating spraying device, the left and right sides of the condensation collection outer cavity are respectively provided with mounting ports, and mounting plates are covered on the mounting ports.
[0018] In the aforementioned atomizing circulating spraying device, the vacuum guide blows gas into the circulating airflow buffer chamber and then into the atomizing chamber. Active ingredient raw materials and compressed air enter the atomizer through the liquid inlet and air inlet of the atomizer, respectively. The atomizer atomizes the active ingredient raw materials into tiny droplets that disperse within the atomizing chamber. These atomized droplets are then propelled by the gas flowing from the circulating airflow buffer chamber to the membrane cloth within the atomizing chamber. The atomized droplets adhere evenly to the membrane cloth, forming a wall-hanging effect on the inner wall of the atomizing chamber. This active ingredient liquid flows into the wall-hanging liquid collection tank. The active ingredient liquid in the wall-hanging liquid collection tank flows through the wall-hanging liquid return pipe to the condensate collection outer chamber and then along the collection trough and pipe to the condensate collection bottle.
[0019] Most of the atomized gas flows to the condenser one through the return cavity. After the atomized gas is condensed by the condenser one, part of the evaporated active material condenses into liquid, forming a wall-hanging effect on the condenser one, and then flows back to the condensate collection bottle two through the pipe. The other part of the atomized gas that has completed condensation exits the condenser one and flows to the suction end of the vacuum guide one through the pipe to complete most of the internal airflow circulation.
[0020] The remaining atomized gas overflows into the condensation and collection outer cavity through the gap between the atomization chamber and the return chamber, and is then transported through pipes to condensers two, three, and four. After being condensed by condensers two, three, and four, a portion of the evaporated active material condenses into liquid, forming a wall-mounting effect in each condenser before flowing back through pipes to the condensate collection bottle one. After condensation, the atomized gas exits each condenser and flows through pipes to vacuum guide valve two, where it is discharged into the outdoor atmosphere under the guidance of vacuum guide valve two, thus completing the condensation and recovery of active material in the condensation and collection outer cavity.
[0021] In the aforementioned atomizing circulating spraying device, under the action of the second vacuum guide, the internal air pressure of the condensation and collection outer cavity is lower than the external atmospheric pressure, and the atomized gas in the condensation and collection outer cavity will not flow out from the gaps of the condensation and collection outer cavity. The active material formed on the inner wall of the condensation and collection outer cavity and the active material flowing out from the wall liquid return pipe will be collected in the liquid collection tank, and then flow through the pipeline to the first condensate collection bottle.
[0022] The atomizing circulating spraying device of this utility model has the following beneficial effects:
[0023] (1) After the active ingredient is atomized, the atomization circulation guide mechanism can attach a small amount (note: the amount of active ingredient attached is not necessarily the more the better) and evenly to the surface of the freeze-dried mask. Compared with spraying or immersing the active ingredient to the surface of the mask, the amount of active ingredient attached can be greatly reduced and its uniformity of attachment can be guaranteed.
[0024] (2) The use of concentrated atomization adhesion can reduce the volatilization of atomized gas in the atomization chamber, improve the adhesion rate, and improve the utilization of atomized gas in circulation;
[0025] (3) The condenser can condense and recover the active liquid that has evaporated into the air, which can improve the utilization rate of the active material and reduce the pollution of other equipment caused by the outflow and solidification of the active material, thus avoiding cleaning dead spots or damage to other equipment.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, its specific embodiments are described in detail below with reference to the accompanying drawings:
[0033] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The preferred embodiment of this utility model is an atomizing circulating spraying device, which includes a frame 1, a condensation and collection outer cavity 2, a membrane cloth guiding mechanism 7, and two sets of atomizing circulating guiding mechanisms.
[0034] Two sets of atomizing circulation guiding mechanisms are set on the frame 1, one on the left and one on the right;
[0035] Each atomizing circulation guiding mechanism includes an atomizing circulation inner cavity 3, a wall-mounted liquid return pipe 4, a vacuum guide 1 5, a vacuum guide 2 6, a condensate collection bottle 1 16, a condensate collection bottle 2 17, and four condensers. The atomizing circulation inner cavity is located inside the condensate collection outer cavity 2. The atomizing circulation inner cavity 3 is composed of a circulating airflow buffer cavity 31, an atomizing cavity 32, and a return cavity 33 connected sequentially from top to bottom. A buffer mesh plate 37 is provided between the circulating airflow buffer cavity 31 and the atomizing cavity 32. A slit for the membrane cloth to pass through is provided between the atomizing chamber 32 and the return chamber 33. The four condensers are arranged sequentially from back to front: condenser 11, condenser 2 12, condenser 3 13, and condenser 4 14. The cold water inlets and outlets of condensers 11, 2 12, 3 13, and 4 14 are connected in series via pipes. Cooling water flows in from the cold water inlet 15 of condenser 4 14, flows sequentially through condensers 4 14, 3 13, 2 12, and 11, and then flows into condenser 11 from the cold water inlet / outlet 16. The four condensers are fixed to the frame 1 by condenser mounting brackets 18 and are located outside the condensation collection outer chamber 2.
[0036] An atomizer 9 is installed inside the atomizing chamber 32. Specifically, an atomizer mounting bracket 91 is vertically installed inside the atomizing chamber 32, and the atomizer 9 is mounted on the atomizer mounting bracket 32 in an adjustable manner.
[0037] The atomizing chamber 32 is provided with an atomizer liquid inlet 34 and an atomizer air inlet 35 connected to the atomizer 9. The inner wall of the atomizing chamber 32 is provided with a wall-mounted liquid collection tank 36. The bottom of the condensation collection outer chamber 2 is provided with a liquid collection tank 21. The wall-mounted liquid collection tank 36 is connected to one end of the wall-mounted liquid return pipe 4, and the other end of the wall-mounted liquid return pipe 4 is connected to the liquid collection tank 21. The liquid collection tank 21 is connected to the condensate collection bottle 16 through a pipe.
[0038] The gas inlet of condenser 11 is connected to the reflux chamber 33 via a pipe; the gas outlet of condenser 11 is connected to the suction end of vacuum guide 5; the blowing end of vacuum guide 5 is connected to the circulating airflow buffer chamber 31; and the liquid outlet of condenser 11 is connected to the condensate collection bottle 17.
[0039] The gas inlets of condenser 2 12, condenser 3 13 and condenser 4 14 are connected to the condensation collection outer cavity 2 via pipes; the gas outlets of condenser 2 12, condenser 3 13 and condenser 4 14 are connected to the suction end of vacuum guide 2 6 via pipes, and the blowing end of vacuum guide 2 6 is open to the outside atmosphere; the liquid outlets of condenser 2 12, condenser 3 13 and condenser 4 14 are connected to condensate collection bottle 1 16 via pipes.
[0040] The atomizing circulation chambers 3 of the two sets of atomizing circulation guiding mechanisms are arranged adjacent to each other.
[0041] A membrane fabric guiding mechanism 7 is mounted on the frame 1 to guide the membrane fabric 8 through the gap between the atomization chamber 32 and the return chamber 33. The membrane fabric guiding mechanism 7 includes several membrane fabric guide rollers 71 arranged in a Z-shape, which are mounted on the frame 1. The membrane fabric 8 passes through the gap between the atomization chamber 32 and the return chamber 33 via the membrane fabric guide rollers 71, facilitating the atomizer 9 to attach the atomized active material to the surface of the membrane fabric.
[0042] An acrylic cover plate 22 is provided at the top of the condensation collection outer cavity 2. Installation ports are provided on the left and right sides of the condensation collection outer cavity 2, and installation plates 23 are covered by these ports. Operators can install and clean the equipment through the acrylic cover plate 22 and the installation ports.
[0043] Please see Figure 6 Clean compressed air is injected through vacuum guide 5, causing the air at the suction end 51 (lower end) of vacuum guide 5 to flow to the blowing end 52 (upper end) of vacuum guide 5. The suction gas is 3 times the amount of clean compressed air, and the blowing gas is 4 times the amount of clean compressed air, that is, the suction gas is 75% of the blowing gas.
[0044] In this invention, the atomizing circulating spraying device operates with two sets of atomizing circulating flow guiding mechanisms working simultaneously. Vacuum guide 5 blows gas into the circulating airflow buffer chamber 31 and then into the atomizing chamber 32. Active ingredient raw materials and compressed air enter the atomizer 9 through the liquid inlet 34 and air inlet 35, respectively. The atomizer 9 atomizes the active ingredient raw materials into tiny droplets that disperse in the atomizing chamber 32. These atomized droplets then flow from the circulating airflow buffer chamber 31... Under the blowing of the gas, the liquid is delivered to the membrane cloth 8 in the atomization chamber 32. The atomized droplets are evenly attached to the membrane cloth 8, forming a wall-hanging effect on the inner wall of the atomization chamber 32. When the droplets accumulate to a certain size, they flow into the wall-hanging liquid collection tank 36 of the atomization chamber 32 under the action of gravity. The active liquid in the wall-hanging liquid collection tank 36 flows to the condensation collection outer chamber 2 through the wall-hanging liquid return pipe 4, and then flows along the liquid collection tank 21 through the pipe to the condensate collection bottle 16.
[0045] Most of the atomized gas (approximately 75%) flows to condenser 11 through return chamber 33. After being condensed by condenser 11, a portion of the evaporated active material condenses into liquid, forming a wall-mounting effect on condenser 11, and then flows back to condensate collection bottle 17 through a pipe. The other portion of the condensed atomized gas exits condenser 11 and flows through a pipe to the suction end of vacuum guide 5 to complete 75% internal airflow circulation.
[0046] The remaining atomized gas (approximately 25%) overflows into the condensation and collection outer chamber 2 through the gap between the atomization chamber 32 and the return chamber 33, and is then transported through pipes to condenser 2 12, condenser 3 13, and condenser 4 14. After being condensed by condenser 2 12, condenser 3 13, and condenser 4 14, a portion of the evaporated active material condenses into liquid, forming a wall-mounting effect in each condenser, and then flows back through pipes to the condensate collection bottle 1 16. After condensation, the atomized gas exits each condenser and flows through pipes to vacuum guide 2 6, where it is discharged to the outdoor atmosphere under the guidance of vacuum guide 2 6, thus completing the condensation and recovery of active material in the condensation and collection outer chamber 2.
[0047] Under the action of vacuum guide 26, the internal air pressure of condensation collection outer cavity 2 is lower than the external atmospheric pressure. The atomized gas in condensation collection outer cavity 2 will not flow out from the gaps of condensation collection outer cavity 2. The active material formed on the inner wall of condensation collection outer cavity 2 and the active material flowing out from the wall liquid return pipe 4 will be collected in the liquid collection tank 21 and then flow into the condensate collection bottle 16 through the pipeline.
[0048] The condensation surface of a single condenser is 0.9m. 2 The condensing surface of the condenser-11, composed of two sets of atomizing circulation guiding mechanisms, is 1.8m. 2 The condensation surface formed by the two sets of atomizing circulation guiding mechanisms—condenser 2 (12), condenser 3 (13), and condenser 4 (14)—is 5.4 m². 2 This ensures the condensation effect of the entire device, significantly reducing the volatilization and overflow of active materials.
[0049] In summary, the atomizing circulating spraying device of this invention can atomize the active ingredient into tiny droplets, which are then uniformly and in small quantities applied to the surface of the freeze-dried mask under the guidance of the atomizing circulating flow guiding mechanism. Furthermore, the overflowing atomized active ingredient gas is condensed and recovered for reuse. The yield of active ingredient in the mask can reach over 87.5%, which is more than 10 times higher than that of existing technologies. This significantly reduces the volatilization of active ingredients and the pollution of other infrastructure caused by overflowing active ingredients.
