Description
Technical Field
The utility model mainly relates to a circuit board preparation field is particularly, is a spiral stopper that prevents back flow swirl.
Background
In the manufacture of printed circuit boards, some manufacturing processes need to use a chemical water immersion method, the chemical water in the tank is conveyed into an immersion box by a water pump through a pipeline, and the chemical water in the immersion box can also flow back into a chemical water tank through a return pipe, so that the cyclic utilization of the chemical water is realized. When liquid medicine in the box that soaks flows back in the liquid medicine groove through the back flow, the mouth of pipe liquid that flows back in the box that soaks can produce the swirl, and the production of swirl can be followed and inhaled the air, makes and produces the foam in the liquid medicine groove, and the production of foam can accelerate the consumption of liquid medicine, also can influence the quality of preparation circuit board.
The above disadvantages need to be solved.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a spiral plug for preventing backflow vortex.
The technical scheme of the utility model as follows: the spiral plug is characterized by comprising a panel, wherein one surface of the panel is connected with a connecting column, the cross sectional area of the panel is larger than that of the connecting column, at least two flow guide strips are arranged on the connecting column, and the flow guide strips are spirally wound on the surface of the connecting column.
According to above-mentioned structure the utility model discloses, its characterized in that still lies in, the quantity of water conservancy diversion strip is 3, and evenly distributed in on the spliced pole.
According to the structure of the utility model discloses, its still characterized in that, the panel with the shape of spliced pole is cylindrical.
Further, the cross-sectional diameter of the panel is larger than the cross-sectional diameter of the connecting column.
According to the above structure the utility model discloses, its still characterized in that, the spliced pole is located the positive intermediate position of panel one side.
According to above-mentioned structure the utility model discloses, its effect lies in, the utility model discloses when the preparation circuit board is soaked with liquid medicine, make partial liquid medicine flow back from the guiding gutter that forms between two adjacent water conservancy diversion strips of side, prolonged the backward flow route of liquid medicine to reduce the impact of liquid medicine backward flow, also slowed down the speed that liquid medicine flows back, reduced because of the probability that liquid medicine backward flow produced the foam, practiced thrift printed circuit board's time, improved printed circuit board's efficiency. The utility model discloses the structure is small, simple to operate, and is easy and simple to handle, safe and reliable moreover, low cost for the user provides convenience, does use on the device that needs prevent liquid reflux.
Drawings
Fig. 1 is a side view of the present invention.
Fig. 2 is a front view of the present invention.
Fig. 3 is a schematic view of the usage status of the present invention.
In the figure: 1. a panel; 2. connecting columns; 3. a flow guide strip; 4. a liquid medicine tank; 5. a soaking box; 6. a return pipe.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1-2, the utility model discloses a prevent spiral plug of back flow vortex, including panel 1, the one side of panel 1 links to each other with spliced pole 2, and the cross-sectional area of panel 1 is greater than spliced pole 2's cross-sectional area, is equipped with two at least water conservancy diversion strips 3 on the spliced pole 2, and 3 spiral windings of water conservancy diversion strip are on spliced pole 2 on the surface.
The number of the flow guide strips 3 is 3, and the flow guide strips are uniformly distributed on the connecting column. The quantity of water conservancy diversion strip can change according to the size of actual spliced pole diameter, and the flow of liquid medicine is big more, and the diameter of spliced pole is big more, and the quantity of water conservancy diversion strip is just more. A diversion trench is formed between two adjacent diversion strips, and the diversion trench is arranged to allow the liquid medicine to pass through the diversion trench, so that the flow path of the liquid medicine is increased, and the generation of vortexes in the liquid medicine is reduced.
The panel 1 is cylindrical in shape and the connecting column 2 is cylindrical in shape. The cylindrical shape can make the liquid medicine flow more smoothly, and the phenomenon of jam is difficult to produce.
The cross section diameter of panel 1 is greater than the cross section diameter of spliced pole 2, and spliced pole 2 is located the positive middle position of panel 1 one side. The cross section diameter of panel is greater than the cross section diameter of spliced pole, the panel has played the effect of a jam like this, can prevent flowing down of liquid medicine, can also effectually block flowing down of some liquid medicines after extracting the panel, slow down the speed of rivers, be used for reducing the production of swirl in the liquid medicine, and the spliced pole setting is on the position in the middle of the panel, the liquid medicine stream on both sides can be very even from flowing through, not only reached the smooth pleasing to the eye effect of exterior lines, perfect speed that has slowed down the liquid medicine stream again.
Fig. 3 is the utility model discloses need use the embodiment in the water immersion method at printed circuit board, the one end of back flow 6 is connected to the bottom of soaking box 5, and liquid medicine groove 4 is connected to the other end of back flow 6, and the bottom of soaking box 5 is installed with the place that back flow 6 is connected the utility model discloses a plug screw, wherein, liquid medicine flows according to the direction of arrow point in the picture. The utility model discloses the effectual distance that increases the liquid medicine backward flow has slowed down the speed of liquid medicine backward flow, the successful production that has prevented the liquid medicine foam.
The utility model discloses when preparation circuit board and soak with liquid medicine, make partial liquid medicine flow back from the guiding gutter that forms between two adjacent water conservancy diversion strips of side, prolonged the backward flow route of liquid medicine to reduce the impact of liquid medicine backward flow, also slowed down the speed that liquid medicine flows back, reduced because of the probability of liquid medicine backward flow production foam, practiced thrift printed circuit board's time, improved printed circuit board's efficiency. The utility model discloses the structure is small, simple to operate, and is easy and simple to handle, safe and reliable moreover, low cost for the user provides convenience, does use on the device that needs prevent liquid reflux.
