Detailed Description
The following describes in further detail embodiments of the present invention.
As shown in fig. 1, the device for testing surface cleanliness of metal castings of the present invention comprises an upper bottle 10 and a lower bottle 12 with opposite bottle openings. The upper bottle 10 and the lower bottle 12 are glass bottles for easy production and observation. The diameters of the bottle openings of the upper bottle 10 and the lower bottle 12 are the same, and the outer sides of the bottle openings of the upper bottle 10 and the lower bottle 12 are provided with edges (not shown) protruding outwards. A filter paper (not shown) is disposed between the upper bottle 10 and the lower bottle 12, and the upper bottle 10 and the lower bottle 12 are connected together by a fastener 14.
In embodiment 1, the fastening member 14 is a clip including a U-shaped clamp portion 16 for clamping the edges of the mouths of the upper bottle 10 and the lower bottle 12, which can achieve quick fastening and improve efficiency.
In embodiment 2, the fastener 14 is a U-shaped anchor ear. The anchor ear is of a construction commonly known in the art and is therefore not shown in detail.
The upper bottle 10 is provided with a water inlet (not shown), the lower bottle 12 is provided with a water outlet 20, and further comprises a water storage tank 22, a water supply pump 30 feeds water in the water storage tank 22 into the upper bottle 10 through a water inlet pipe 24 penetrating through the water inlet, and a water discharge pump (not shown) discharges water in the lower bottle 12 into the water storage tank 22 through a water discharge pipe 26 penetrating through the water outlet 20. The drain pump is not an essential component and can also be used to effect drainage by direct siphoning, but at a slower rate, so the use of a drain pump is most effective.
A filter (not shown) is provided in the water storage tank 22, and the water supply pump feeds the water filtered by the filter into the upper bottle 10.
The bottom of the upper bottle 10 is open, and an upper cover 28 for closing the opening is provided, and the water inlet hole may be provided on the side wall of the upper bottle 10 or the upper cover 28.
The working principle is as follows: after the upper bottle 10 and the lower bottle 12 are fixed, the upper cap 28 is opened and the test piece 32 is placed. The water supply pump 30 then sends water to wash the test piece 32, and the impurities are collected by the filter paper. The dirty water flows into the lower bottle 12 and is pumped by the drain pump to the reservoir 22 for recycling. Drying and weighing the filter paper before use, and drying and weighing the filter paper after use, wherein the weight of impurities on the filter paper can be known through two weight comparisons; the used filter paper is photographed, and the number of impurities on the filter paper and the diameter of the filter paper can be obtained through the analysis of the image.
The above embodiment is only one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
