Description

The invention relates to devices for purifying a liquid, mainly milk, and can be used in a set of equipment for purifying milk from mechanical impurities in livestock farms and farms, as well as in milk collecting centers, dairy and cheese-making plants.

The aim of the invention is to reduce the complexity of manufacturing a filter device and increase its throughput.

Figure 1 shows a filtering device, a longitudinal section; in Fig.2 - view along arrow A in Fig.1; Fig. 3 is a frame, axonometric view.

The filtering device comprises a cylindrical housing 1 with inlet 2 and outlet 3 nozzles and a cylindrical frame coaxially mounted in it with filter sleeves 4. The cylindrical frame is formed by tubular elements 6 cantileverly attached to the supporting disk 5, having openings 7 for the passage of milk, for example, round , oval, slit-shaped or other shape. The casing 1. Is equipped with an outlet pipe located between its end wall 8c and a supporting disk 5 of the frame with a collection chamber 9, the cavity of which is in communication with the cavities of the tubular elements .6.

Tubular electrical elements 6 are connected in pairs by filtering sleeves 4. In this case, each filtering sleeve 4 with open ends is worn respectively on the tubular elements 6 constituting a pair, and the middle part 10 of the sleeve 4 is located between the cantilever ends of the tubular elements

6 above the level of the latter. The open ends of the filter sleeve 4 are fixed. On the supporting disk 5 of the frame by means of locking rings 11.

The tubular elements 6 can have a cross-sectional shape of a circle, .ovial or polygon, and can also be installed at different angles to the plane of the supporting disk 5 and have different linear sizes relative to each other.

The filter device is used as follows, j

} Monaco, flowing through the milk pipeline, enters, for example, tangentially through the inlet pipe 2 into the filter housing 1 of the filter device and washes the outer, inner and end surfaces of the frame. In this case, milk, washing the surface of the filter bags 4, seeps through the pores of the filter (bag) and the holes 7 of the tubular elements b into the cavity of the latter, leaving particles of dirt on the surface of the bag 4. Next, the filtrate from the cavities of the pipe elements 6 enters the collection chamber 9. B to the collection chamber 9, the filtrate flows coming into it are mixed, and then the poor filtrate is discharged from the collection chamber through the outlet pipe 3, for example, to a cooler. When washing the filter device, the sleeves 4 are removed from the frame and removed from the housing 1.

The proposed implementation of the filter device allows to increase it

throughput due to the implementation of a developed filter surface (perforated tubular elements with filter bags). However, the pairwise connection of the tubular elements with a filter sleeve contributes to the formation of an additional filter surface located in the plane of the cantilever ends of the tubular elements, which also leads to an increase in the throughput of the filter device. The implementation and laying of the filter sleeve allows 1.5 times to reduce labor costs for its manufacture due to the exclusion of 5 operations of transverse cutting-welding of the bag filter.
