Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass frosting, and specifically to a glass frosting device. Background Technology
[0002] Glass frosting is a processing technique that alters the surface properties of glass to create a matte finish. The frosting process involves applying a frosting solution to the glass surface. Traditional frosting equipment sprays the solution onto the glass surface, but the solution cannot be evenly distributed across all areas, resulting in varying degrees of frosting and a less aesthetically pleasing finish.
[0003] Later, a type of sandblasting water jet with improved residue removal, as disclosed in patent number CN217323883U, appeared. It consists of an inlet pipe, a base plate, end plates connected to both ends of the base plate, and a back plate connected to one side of the base plate. The two ends of the back plate are connected to the two end plates respectively. A first overflow plate, a second overflow plate, and a third overflow plate are vertically arranged between the two end plates. The first overflow plate is located between the second overflow plate and the back plate. The first overflow plate has an overflow hole. The height of the top of the end plate, the top of the second overflow plate, and the top of the third overflow plate decreases sequentially. The side of the third overflow plate away from the second overflow plate is arc-shaped, and the bottom of the side of the third overflow plate away from the second overflow plate is connected to the edge of the base plate. The outlet end of the inlet pipe is located between the first overflow plate and the back plate.
[0004] In the aforementioned waterjet frosting process, the frosting solution enters the equipment and passes through the first and second overflow plates sequentially, finally flowing down from the third overflow plate to form a water curtain. The water curtain is more stable due to the obstruction and limiting effect of the three overflow plates, allowing for more uniform frosting as the glass passes through it at a constant speed. However, in actual use, because the frosting solution mainly consists of supersaturated aqueous solutions of etchants such as hydrofluoric acid, grain-forming agents such as sodium sulfate, and suspending agents such as starch and glycerin, sedimentation occurs over prolonged use. Therefore, when using the aforementioned equipment, sedimentation occurs between the first and second overflow plates, and between the second and third overflow plates. This causes the frosting solution that crosses the second and third overflow plates to become thinner, resulting in a poorer frosting effect. Utility Model Content
[0005] The present invention aims to provide a glass frosting device to solve the problem that the frosting liquid becomes thinner and the frosting effect deteriorates.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a glass frosting device, including a water tank, a baffle is vertically provided in the water tank, the baffle divides the water tank into an inlet tank and an outlet tank, an inlet pipe is provided in the inlet tank, and an outlet for introducing frosting liquid into the water tank is provided on the inlet pipe, a notch is provided on the side wall of the outlet tank, an overflow plate is provided at the notch, a plurality of overflow holes are provided at the lower part of the baffle, all the overflow holes are distributed sequentially along the width direction of the overflow plate; the upper end of the overflow plate extends into the outlet tank and is fixed with a guide plate, the guide plate and the overflow plate are smoothly transitioned, and the top of the guide plate is higher than the overflow holes.
[0007] The beneficial effects of this plan are:
[0008] 1. The baffle in this design has an overflow hole at the bottom. When the frosting liquid in the inlet tank overflows the overflow hole, it will flow into the outlet tank from the overflow hole. Compared with the current design where the frosting liquid overflows the baffle and flows from the top of the baffle to the outlet tank, the overflow hole in this design is located at the bottom of the baffle. With the same baffle height, the overflow hole design allows the frosting liquid at a lower position to flow out. Even if the frosting liquid settles in the inlet tank, the sediment can flow from the overflow hole to the outlet tank. During this process, since the frosting liquid is in a flowing state, the sediment will dissolve back into the frosting liquid, preventing the frosting liquid from becoming thinner and thus maintaining a better frosting effect.
[0009] Compared to setting a strip-shaped opening below the baffle, the design of several overflow holes in this scheme can reduce the space for the frosting liquid to pass through the baffle, improve the baffle's blocking effect on the frosting liquid, and thus better buffer the frosting liquid, making the flow of the frosting liquid in the outlet tank more stable. The liquid surface of the frosting liquid in the outlet tank will not fluctuate, so the frosting liquid on the overflow plate flows downward evenly, and the frosting effect of all parts of the glass is more uniform.
[0010] 2. This design incorporates a guide plate. Because the guide plate is higher than the overflow hole, the level of the frosting solution in the tank is also higher than the overflow hole. The frosting solution entering the outlet tank from the overflow hole is less likely to form ripples on the surface, resulting in a uniform thickness of the frosting solution flowing out from all positions on the overflow plate. Secondly, the guide plate guides the outflowing frosting solution, allowing it to flow more smoothly and evenly onto the overflow plate, further promoting uniform outflow. Finally, because only one overflow plate is used, the frosting device in this design is narrower and occupies less space.
[0011] Furthermore, side plates are provided on both sides of the overflow plate.
[0012] The beneficial effect of this solution is that the side plate limits the frosting liquid on the overflow plate, thereby preventing the frosting liquid from leaking from the side of the overflow plate.
[0013] Furthermore, the lower and upper surfaces of the overflow plate form a "<" shape with gradually decreasing thickness at the lower end of the overflow plate.
[0014] The beneficial effects of this solution are as follows: the lower end of the overflow plate is the ridge where the upper and lower surfaces meet. After the frosting liquid flows to the lower end of the overflow plate, it will not flow along the rear side wall of the overflow plate to the side closer to the rear side wall, thus avoiding some of the frosting liquid splashing backward onto the glass that has already passed through the frosting liquid water curtain, which would cause uneven frosting.
[0015] Furthermore, multiple liquid inlet pipes are provided, and these multiple liquid inlet pipes are arranged sequentially along the width direction of the overflow plate.
[0016] The beneficial effect of this solution is that multiple inlet pipes can more evenly introduce the frosting solution into the water tank.
[0017] Furthermore, each inlet pipe has multiple outlets, which are distributed sequentially along the length of the inlet pipe, and outlets are distributed on both sides of the inlet pipe.
[0018] The beneficial effects of this solution are: multiple outlets allow the frosting solution to flow out of the inlet pipe more evenly, and the outlets are distributed on both sides of the inlet pipe, which enables the frosting solution entering the inlet tank to flow in the inlet pipe, thereby avoiding the sedimentation of the frosting solution.
[0019] Furthermore, the gap between adjacent overflow holes is 1.5~3cm.
[0020] Furthermore, the diameter of the overflow hole is 0.7~1.5cm.
[0021] The beneficial effects of this solution are as follows: The design of this solution allows the baffle to maintain a good shielding and buffering effect on the sanding liquid in the water inlet tank, while the overflow hole can also provide enough space for the sanding liquid to flow out along the overflow plate, making the flow of sanding liquid on the overflow plate more stable and uniform.
[0022] Furthermore, the lower end of the overflow plate extends to the bottom of the water tank.
[0023] The beneficial effects of this solution are as follows: During the frosting process, the glass to be treated passes under the water tank and the overflow plate. The lower end of the overflow plate in this solution is lower, so the distance between the overflow plate and the glass is smaller, and the frosting liquid will not splash due to excessive kinetic energy when it comes into contact with the glass. Attached Figure Description
[0024] Figure 1 This is a perspective view of an embodiment of the present utility model;
[0025] Figure 2 for Figure 1 Enlarged view of point A in the middle. Detailed Implementation
[0026] The following detailed description illustrates the specific implementation method:
[0027] The reference numerals in the accompanying drawings include: water tank 1, liquid outlet tank 11, liquid inlet tank 12, water inlet pipe 2, water outlet 21, baffle 3, overflow hole 31, overflow plate 4, side plate 41, and guide plate 5.
[0028] Example
[0029] The implementation examples are basically as follows Figure 1 and Figure 2 As shown, the glass frosting device includes a water tank 1, an overflow plate 4, and a baffle 3. The baffle 3 is vertically disposed in the water tank 1 and fixed to the side wall of the water tank 1, dividing the water tank 1 into an inlet tank 12 on the right and an outlet tank 11 on the left. The lower part of the baffle 3 is provided with a plurality of overflow holes 31 along the width direction of the water tank 1. In this embodiment, the diameter of the overflow hole 31 is 1cm, the distance between adjacent overflow holes 31 is also 1cm, and the distance between the bottom of the overflow hole 31 and the lower end of the baffle 3 is 2cm.
[0030] Four inlet pipes are provided in the inlet tank 12 along its width, and multiple outlets 21 are provided on the inlet pipes along their length. All outlets 21 are distributed on the front and rear sides of the inlet pipes, which promotes the flow of frosting liquid in the tank 1 and reduces sedimentation. The right end of the inlet pipe penetrates the rear side wall of the tank 1 and extends to the outside of the tank 1.
[0031] The left side wall of the outlet tank 11 has a notch, and the overflow plate 4 is located at the notch. The lower surface of the overflow plate 4 abuts against the notch to prevent the frosting liquid from flowing out between the lower surface of the overflow plate 4 and the left side wall of the outlet tank 11. In this embodiment, the overflow plate 4 is inclined with the left end lower than the right end, and the angle between the overflow plate 4 and the bottom of the water tank 1 is 45°. The lower end of the overflow plate 4 extends to the bottom of the water tank 1, and at the lower end of the overflow plate 4, the lower surface of the overflow plate 4 is inclined towards the side closer to the upper surface, forming a "<" shape with the thickness gradually decreasing from right to left. That is, the lower end of the overflow plate 4 is the edge where the upper and lower surfaces intersect.
[0032] Two side plates 41 are integrally fixed to the upper surface of the overflow plate 4. The side plates 41 are located on both sides of the overflow plate 4 and are used to limit the frosting liquid on the overflow plate 4 to prevent the frosting liquid from leaking from the front and rear sides of the overflow plate 4. A guide plate 5 is integrally formed at the upper end of the overflow plate 4. The guide plate 5 is horizontally set and the top of the guide plate 5 is slightly higher than the overflow hole 31, so that the liquid level of the frosting liquid in the liquid outlet tank 11 can be higher than the overflow hole 31. The upper surfaces of the guide plate 5 and the overflow plate 4 are smoothly transitioned.
[0033] The specific implementation process is as follows:
[0034] Initially, the frosting solution enters the inlet tank 12 through the inlet pipe. As more frosting solution enters, the liquid level in the inlet tank 12 gradually rises. Finally, the frosting solution flows through the overflow hole 31 into the outlet tank 11. When the liquid level in the outlet tank 11 is higher than the top of the guide plate 5, the frosting solution in the outlet tank 11 flows out through the guide plate 5 and flows downward along the overflow plate 4, forming a water curtain below the overflow plate 4. The frosted glass passes under the overflow plate 4 and is treated by the frosting solution as it passes through the water curtain.
