Description

Technical Field

[0001] This utility model relates to the field of foam elimination technology, and in particular to a foam elimination device for dampening solution. Background Technology

[0002] Dampening solution is a chemical solution used in offset printing to wet the printing plate and maintain the water-ink balance. It is also called dampening solution, water tank solution, or water fountain solution. Its main function is to ensure that the non-image areas of the printing plate are hydrophilic and oleophobic, and to prevent ink from spreading.

[0003] However, in existing technologies, dampening solutions are generally filled into dampening solution tanks for use by printing presses. When the dampening solution is poured into the tank, air is easily drawn into the liquid due to the liquid impact, forming foam. Once formed, the foam does not dissipate for a long time. To avoid supplying foamy dampening solution to the printing press and affecting printing quality, a dampening solution defoamer is usually added to the dampening solution tank at the same time to quickly remove the foam. In order to ensure that the dampening solution defoamer and dampening solution are evenly mixed to ensure the defoaming effect, the dampening solution with added defoamer is usually stirred. However, during the stirring process, new foam is usually generated, which affects the defoaming efficiency of the dampening solution. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies: In order to ensure the defoaming effect of the damping solution by uniformly mixing the defoamer with the damping solution, the damping solution with added defoamer is usually stirred. However, during the stirring process, new foam is usually generated, which affects the defoaming efficiency of the damping solution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fountain solution foam elimination device, comprising a fountain solution storage tank, wherein an inlet pipe and an outlet pipe are respectively fixedly connected through the upper surface and side surface of the fountain solution storage tank, and a solenoid valve is fixedly installed on the surface of the outlet pipe; a defoamer storage tank is fixedly installed on the side of the fountain solution storage tank away from the outlet pipe; a suction pipe is fixedly connected through the lower end of the defoamer storage tank, and a water pump is fixedly installed at one end of the suction pipe; a delivery pipe is fixedly installed at the output end of the water pump, and the delivery pipe is fixedly connected through the top of the fountain solution storage tank; a square ring pipe is fixedly connected through the delivery pipe at the connecting pipe end inside the fountain solution storage tank, and the square ring pipe is fixedly connected to the inner surface of the fountain solution storage tank; a cross pipe is fixedly connected through the surface of the square ring pipe, and nozzles are fixedly connected through the surfaces of both the square ring pipe and the cross pipe.

[0006] In a preferred embodiment, a funnel is fixedly connected to one end of the liquid inlet pipe.

[0007] In a preferred embodiment, the dampening solution storage tank has an opening on the front side, and a transparent glass is fixedly installed on the surface of the opening.

[0008] In a preferred embodiment, a fixing frame is fixed on the surface of the liquid delivery tube, and one end of the fixing frame is fixedly connected to the surface of the dampening solution storage tank.

[0009] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0010] This invention facilitates the extraction of defoamer from the damping solution storage tank using a suction pipe, a water pump, and a delivery pipe. The defoamer then flows gradually through the suction pipe, delivery pipe, square ring pipe, and cross pipe before being sprayed out from the nozzle. Because the square ring pipe and cross pipe are evenly arranged in multiple layers within the damping solution storage tank, the defoamer is uniformly mixed in the damping solution after being sprayed out, eliminating the need for stirring and reducing bubble formation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a fountain solution foam elimination device, including a fountain solution storage tank 1. An inlet pipe 2 and an outlet pipe 3 are respectively fixedly connected to the upper and side surfaces of the fountain solution storage tank 1. The fountain solution is poured into the fountain solution storage tank 1 through the inlet pipe 2 for storage, and flows out through the outlet pipe 3 to the printing press for use. A solenoid valve 4 is fixedly installed on the surface of the outlet pipe 3, which seals the internal passage of the outlet pipe 3 to prevent the fountain solution from flowing out when not in use. An defoamer storage tank 7 is fixedly installed on the side of the fountain solution storage tank 1 away from the outlet pipe 3. The defoamer storage tank 7 is used to store fountain solution defoamer. A suction pipe 8 is fixedly connected to the lower end of the defoamer storage tank 7, and a water pump 9 is fixedly installed at one end of the suction pipe 8. A delivery pipe 10 is fixedly installed at the output end of the water pump 9, and the delivery pipe 10 is fixedly connected to the top of the fountain solution storage tank 1. When the water pump 9 starts, it extracts the dampening solution defoamer stored inside the defoamer storage tank 7. During the extraction process, the dampening solution defoamer gradually flows through the extraction pipe 8, delivery pipe 10, square ring pipe 12, and cross pipe 13. Finally, the dampening solution defoamer is sprayed out from the nozzle 14 to defoam the dampening solution in the dampening solution storage tank 1. The delivery pipe 10 is located inside the damping solution storage tank 1 and is fixed with a square ring at the connecting pipe joint. The square ring tube 12 is fixedly connected to the inner surface of the dampening solution storage tank 1. A cross tube 13 is fixedly connected through the surface of the square ring tube 12. A nozzle 14 is fixedly connected through the surface of both the square ring tube 12 and the cross tube 13. Since the square ring tube 12 and the cross tube 13 are evenly arranged in multiple layers in the dampening solution storage tank 1, the dampening solution defoamer can be evenly mixed in the dampening solution after being sprayed from the nozzle 14, without the need for stirring, thus reducing the generation of bubbles.

[0019] Example 2

[0020] like Figure 1-3 As shown, a funnel 5 is fixedly connected to one end of the inlet pipe 2. With the help of the funnel 5, the opening at the upper end of the inlet pipe 2 is expanded, thereby effectively reducing the spillage of the damping solution during the process of pouring the damping solution into the inlet pipe 2. The front side of the damping solution storage tank 1 has an opening, and a transparent glass 6 is fixedly installed on the surface of the opening. The user can easily observe the inside of the damping solution storage tank 1 through the transparent glass 6 to understand whether there is foam on the damping solution in the damping solution storage tank 1. A fixing bracket 11 is fixed on the surface of the delivery pipe 10, and one end of the fixing bracket 11 is fixedly connected to the surface of the damping solution storage tank 1. With the help of the fixing bracket 11, the stability of the delivery pipe 10 installed on the damping solution storage tank 1 is improved.
