The poor filtering effect is manifested in that if the flow rate is large, the nylon filter bag is easily damaged or falls off, and the large flow rate will also change the mesh size of the nylon filter bag. If there are too many impurities, the filtration speed is slow. Utility Model Content

[0019] The technical solution of the utility model will be clearly and completely described below through specific implementation methods.

[0020] The utility model provides a device for quickly filtering impurities from raw milk, comprising a temporary storage tank 1, the specific structure of which is as follows: Figure 1 As shown, it also includes a pipeline mechanism, a butterfly valve 2, a filter mechanism 3 and a centrifugal pump 4. The pipeline mechanism connects the temporary storage tank 1, the butterfly valve 2, the filter mechanism 3 and the centrifugal pump 4 in sequence; the filter mechanism 3 includes a filter cotton 5 and a filter screen 6 with a U-shaped cross section. The filter screen 6 is fixed inside the pipeline mechanism. A retaining ring 7 is provided along the circumference of the inner side of the filter screen 6. The retaining ring 7 and the bottom of the filter screen 6 form a filter layer 8, as shown in FIG. Figure 3 and 4 As shown, filter cotton 5 is arranged in the filter layer 8. The function of the retaining ring 7 is to retain the filter cotton in the filter layer to prevent improper installation or other reasons from separating from the filter layer and not achieving a good filtering effect.

[0021] Preferably, the outer pore size of the filter cotton 5 is 100-250 μm, and the working pressure is 50 KPa.

[0022] The pipeline mechanism of the utility model includes a first pipeline 9, a second pipeline 10 and a third pipeline 11. The first pipeline 9 connects the temporary storage tank 1 and one end of the butterfly valve 2; the second pipeline 10 connects the other end of the butterfly valve 2 and one end of the third pipeline 11; the other end of the third pipeline 11 is connected to the centrifugal pump 4. Figure 2 As shown, the connection part of the second pipeline 10 and the third pipeline 11 is fixed by a pipe clamp 12. The pipe clamp 12 is a detachable connection structure, which detachably connects the second pipeline 10 and the third pipeline 11, and can facilitate the installation and replacement of the filter cotton 5, as well as the cleaning of the filter screen 6. The fixing structure of the pipe clamp belongs to the prior art and will not be described in this embodiment. The centrifugal pump 4 is also connected to the milk truck through another pipeline so as to timely transport the filtered raw milk to the factory for processing.

[0025] In order to ensure the sealing performance during the raw milk filtration, a sealing gasket 13 may be provided on the connecting end faces of the second pipeline and the third pipeline during the connection. Figure 3 shown.

[0026] The butterfly valve of the utility model is a manual butterfly valve of model SMS51. The main function of the butterfly valve is to control the switch and the opening during filtering, so that it is convenient to close the pipeline in time when the filter screen needs to be cleaned or the filter cotton needs to be replaced.

[0027] The use principle of the utility model is as follows: before filtering the raw milk, filter cotton is installed in the filter screen, and the second pipeline and the third pipeline are fixedly connected by a pipe clamp. When filtering, the centrifugal pump and the butterfly valve are started, and the raw milk extracted by the centrifugal pump passes through the first pipeline and the second pipeline in sequence from the temporary storage tank, passes through the filter cotton and the filter screen at the end of the third pipeline, passes through the centrifugal pump from the third pipeline, and is then transported to the milk truck, thereby completing the filtering of the raw milk.
