Technical Field

[0001] The present application relates to the field of aqueous slurry spraying equipment, and in particular, to a graphene aqueous slurry spraying device. Background Art

[0002] Air-energy heat pumps use the heat in the air to generate heat energy. They can provide the whole family with different hot water, heating and cooling needs with large water volume, high water pressure and constant temperature 24 hours a day, while consuming the least energy to meet the above requirements. Generally, when air-energy heat pumps are used in the cold north, due to the low temperature, many parts of the heat pumps are usually covered with protective covers with graphene materials to achieve better defrosting effect of the parts and speed up the defrosting time of the parts. Therefore, a layer of graphene water-based slurry is usually sprayed on the plastic protective cover to ensure the realization of such effects.

[0003] When spraying, the existing thin film spraying equipment, such as the graphene coating die-cutting device disclosed in China Publication No. CN116984192A, unwinds the film material to be coated through the unwinding device, crosses the surface of the unwinding roller in turn, and then is placed on the surface of the coating table for transportation, and the graphene slurry sprayed on the surface of the film material by the unloading mechanism is evenly spread on the surface of the film material through the coating roller installed on the surface of the fixed shaft, and the graphene slurry is stored and sprayed by the unloading mechanism, which solves the problem that the graphene slurry is exposed for a long time during each coating and printing process, affecting the humidity of the graphene slurry in the subsequent printing process, thereby affecting the coating effect of the device on the graphene. However, since the film is prone to static electricity and dust adhesion, the film has a poor spraying effect when spraying the graphene water-based slurry. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a graphene aqueous slurry spraying device, which aims to improve the problem that the film easily generates static electricity and thus adheres to dust, resulting in poor spraying effect when the film is sprayed with graphene aqueous slurry.

A plurality of temperature control zones are arranged in the drying chamber, and the temperature of each temperature control zone gradually rises and then falls from front to back.

[0007] In a specific embodiment, the static electricity removal component includes a first cylinder, which is installed on the U-shaped processing box located at the outer top of the electrostatic dust removal chamber. The output rod end of the first cylinder movably passes through the top wall of the U-shaped processing box and is installed with a static electricity removal rod. The static electricity removal rod is in contact with the upper surface of the film of the graphene aqueous slurry to be sprayed.

[0008] In a specific embodiment, the dust removal component includes a second cylinder, which is installed on the U-shaped processing box located on the outer top of the electrostatic dust removal chamber, and the second cylinder is located on the rear side of the first cylinder. The output rod end of the second cylinder movably passes through the top wall of the U-shaped processing box and is equipped with a sponge brush.

[0009] In a specific embodiment, two second inclined stabilizing rods are installed above both ends of the sponge brush, and both ends of the two second inclined stabilizing rods are respectively slidably connected to the inner walls on both sides of the electrostatic dust removal chamber.

[0010] In a specific embodiment, two first inclined stabilizing rods are installed above both ends of the static removal rod, and the top ends of the two first inclined stabilizing rods are slidably connected to the inner walls on both sides of the electrostatic dust removal chamber respectively.

[0011] In a specific embodiment, a plurality of partition plates are arranged inside the drying chamber, and each of the partition plates divides the drying chamber into a plurality of temperature control zones.

[0012] In a specific embodiment, a heating tube and a temperature controller are installed inside each temperature control zone, and the heating tube and the temperature controller inside each temperature control zone are electrically connected separately.

[0013] In a specific embodiment, support rollers are provided at both ends of the conveying roller.

[0014] Beneficial effects:

[0015] 1. Through the cooperation of anti-static parts and dust removal parts, the film can be cleaned before spraying to prevent static electricity from adhering to the film and affecting the subsequent spraying effect.

[0016] 2. The multiple temperature control zones set inside the drying chamber can dry the sprayed film and cool it down after drying, so that drying and cooling can be completed simultaneously during transportation, thereby improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1 , Figure 2 , Figure 3 and Figure 4, a U-shaped processing box 2 is installed on the conveyor roller 1, and the U-shaped processing box 2 is divided into an electrostatic dust removal chamber 4, an aqueous slurry spraying chamber 5 and a drying chamber 6 from front to back. The electrostatic dust removal chamber 4 is installed with a static removal component 8 and a dust removal component 9 from front to back. The aqueous slurry spraying chamber 5 is installed with a spraying device. Specifically, the spraying device adopts the existing spraying method and spraying structure for spraying, which is the prior art and will not be described in detail here. A plurality of temperature control zones are arranged inside the drying chamber 6, and the temperature of each temperature control zone gradually rises and then falls from front to back. Among them, when the film needs to be sprayed with graphene aqueous slurry, the film is first placed on the conveyor roller 1 for transportation into the electrostatic dust removal chamber 4, and the static removal component 8 and the dust removal component 9 are started to remove static electricity and dust from the film. After the end, the film enters the aqueous slurry spraying chamber 5 and is sprayed by the spraying equipment. The sprayed film enters the drying chamber 6 for drying and cooling, and then it can be rolled up. The cooperation of the static electricity removal component 8 and the dust removal component 9 can clean the film before spraying to prevent static electricity from adhering to the film and affecting the subsequent spraying effect. The multiple temperature control zones set in the drying chamber 6 can dry the sprayed film and cool it down after drying, so that drying and cooling can be completed simultaneously during transportation, thereby improving production efficiency.

[0026] In this embodiment, the static removal component 8 includes a first cylinder 81, which is installed on the outer top of the U-shaped processing box 2 located at the electrostatic dust removal chamber 4. The output rod end of the first cylinder 81 is movable through the top wall of the U-shaped processing box 2 and is installed with a static removal rod 82. Specifically, the output rod end of the first cylinder 81 is fixedly connected to the first mounting seat, and the static removal rod 82 is installed on the first mounting seat. Two first tilting stabilizing rods 83 are connected to the first mounting seat. The static removal rod 82 contacts the upper surface of the film to be sprayed with the graphene aqueous slurry. Two first tilting stabilizing rods 83 are also installed above the two ends of the static removal rod 82, and the tops of the two first tilting stabilizing rods 83 are respectively slidably connected to the inner walls on both sides of the electrostatic dust removal chamber 4. Among them, the first cylinder 81 makes the static removal rod 82 contact the upper surface of the film to achieve static elimination on the film. The setting of the first tilting stabilizing rod 83 makes the static removal rod 82 more stable when lifting.

[0027] In this embodiment, the dust removal part 9 includes a second cylinder 91, which is installed on the outer top of the U-shaped processing box 2 located at the electrostatic dust removal chamber 4, and the second cylinder 91 is located on the rear side of the first cylinder 81. The output rod end of the second cylinder 91 is movable through the top wall of the U-shaped processing box 2 and is installed with a sponge brush 92. Specifically, the output rod end of the second cylinder 91 is fixedly connected with a second mounting seat, and the sponge brush 92 is installed on the second mounting seat. Two second inclined stabilizing rods 93 are also installed above the two ends of the sponge brush 92, and the two ends of the two second inclined stabilizing rods 93 are respectively slidably connected to the inner walls on both sides of the electrostatic dust removal chamber 4. Among them, the film after static electricity is removed is brushed to remove dust by the sponge brush 92, so as to clean the film and improve the subsequent spraying efficiency of the film.

[0028] In this embodiment, a plurality of partition plates 7 are arranged inside the drying chamber 6, and each partition plate 7 is used to divide the drying chamber 6 into a plurality of temperature control zones. A heating tube 10 and a temperature controller 11 are installed inside each temperature control zone, and the heating tube 10 and the temperature controller 11 inside each temperature control zone are electrically connected separately. Specifically, the temperature of each temperature control zone can be increased and then decreased from front to back, such as the temperature of the first temperature control zone is 60 degrees Celsius, the temperature of the second temperature control zone is 70 degrees Celsius, the temperature of the third temperature control zone is 80 degrees Celsius, the temperature of the fourth temperature control zone is 70 degrees Celsius, and the temperature of the fifth temperature control zone is 60 degrees Celsius. The specific temperature setting is actually changed according to the actual degree of heating of the film, and the number of temperature control zones specifically set is also set according to actual production. Among them, each temperature control zone is heated and dried by each heating tube 10, and the temperature controller 11 can monitor the temperature inside the temperature control zone in real time to ensure that the temperature of each temperature control zone is at the set temperature.

[0029] In the specific configuration, support rollers 3 are provided at both ends of the conveying roller 1. The film is wound up by the two support rollers 3.

[0030] Working principle of the graphene aqueous slurry spraying device:

[0031] When the film needs to be sprayed with graphene aqueous slurry, the film is first placed on the conveyor roller 1 for transportation into the electrostatic dust removal chamber 4, and the static removal component 8 and the dust removal component 9 are started to remove static electricity and dust from the film. After completion, the film enters the aqueous slurry spraying chamber 5 and is sprayed with the film through the spraying equipment. The sprayed film enters the drying chamber 6 for drying and cooling, and then is rolled up. Through the cooperation of the static removal component 8 and the dust removal component 9, the film can be cleaned before spraying to prevent static electricity from adhering to the film and affecting the subsequent spraying effect. The multiple temperature control zones set inside the drying chamber 6 can dry the sprayed film and cool it after drying, so that drying and cooling can be completed simultaneously during transportation, thereby improving production efficiency.

[0032] It should be noted that the specific models and specifications of the first cylinder 81, the anti-static rod 82, the second cylinder 91, the heating tube 10 and the temperature controller 11 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
