Description

SP

00 to 4 The invention relates to filtering, in particular, to devices dp of cleaning a reverse flush filter with simultaneous shaking of the filter element, and can be used in various industries. A known filter comprising a housing, a filter element and a backwash device with an ultrasonic generator L-1. The disadvantages of this filter are the complexity of the design and unreliable operation due to the use of additional electric drive elements and complex switching electrical control circuits. Also known is a filter with automatic regeneration of filtering elements, comprising a housing with chambers inlet and outlet, a filtering element with a face cover and a vibrating device made in the form of a Ka ... L2. Valve. The disadvantages of the known filter are the cumbersome and complexity of the hinge-mounted valve-punching device, its intensity and unreliability of operation. The purpose of the invention is to simplify the device for cleaning the filter element, increase reliability of operation and reduce metal consumption. This goal is achieved by the fact that in the filter comprising a housing with an overhang of entry and exit, the filter element of the end cap has an orifice a vibration device, made in the form of a valve-hammer; the inlet and outlet nozzles, in the lid of the filtering element, are made of a valve chamber with openings connecting it to the inlet and outlet chambers, and a hammer valve is installed in the hole of the lid connecting the valve chamber with the outlet chamber. There is an annular hollow on the caper-drummer, and a saddle with a corresponding hollow in the annular protrusion on the lid of the filter element. In addition, the filter element has the possibility of axial movement. In FIG. 1 shows the filter in the operating mode, the general view; in fig. 2 position of the striker head, located on the top of the filter element, during backwashing. The filter consists of a housing 1, a filtering element 2, a spring 3 of a filtering element, a filtering mesh 4, a valve-hammer 5, eio spring 6, a torped mat 7 of the filtering element with a valve chamber 8, and a hole 9 and Y. a chamber 8 with an inlet chamber 11, and openings Ю connect the valve chamber 8 with the inlet chamber 12. There are also inlet 13 and outlet 14 nozzles and a throttle 15. The device operates as follows. In the operating mode, the contaminated fluid enters through the inlet 13 into the internal cavity of the filter element 2. Under the pressure of the liquid, the filter element 2 moves upward, compressing the spring 3 and opening the slit from the inlet chamber 12 into the output chamber 11 for the passage of the filtered liquid from nozzle 14 into the system. At the same time, dirt particles are trapped on the inner surface of the grid 4. At the same time, the filtered fluid flows through the openings under the lower end of the valve-hammer 5, pressing it against the crutch 7 and closing the opening 9. To flush the filter element 2, the return flow of the filter element 2 under a certain pressure and flow rate is controlled by the throttle 15 ,. From the pressure of the liquid and the spring 3, the cover 7 is pressed against the housing 1, closing the gap between them, the valve-hammer 5 goes down, overcoming the force of the spring 6, and through the gap formed above the valve and the opening 1O begins after the fluid flows through the grid 4 from the chamber 12 the internal cavity of the filter element 2 and further into the pipe 13 and drainage. This molt of fluid washes away particles of dirt accumulated on the inner surface of the mesh 4. As the flow rate increases, due to the shape of the surface of the striker 5, the liquid strings change their direction by almost 180, resulting in an increase in the instantaneous reactive force from the bottom up. on the valve-hammer 5, which is bursting when cutting, hitting the valve 7 of the filter element 2, shaking it. This force can vary quite abruptly depending on the position of the hammer-hammer 5 and the fluid flow rate, which drives the vibrator-valve (hammer-eye) 5 to the hammer-hammer 5 and shakes the pickup element 2.

From the blows of the valve-hammer 5

; the cover 7; the filter element 2 is mixed upward, compressing the spring E,; at the same time, through the shell formed by the cover 7 and the body 1, an additional flow of liquid rushes out, also performs the function of cleaning the grid 4 from dirt

Depending on the flow rate to the backflow fluid pressure, as well as the force of the spring 6, the frequency and energy of the blows of the valve 5 are selected, and the springs 3 and 6 compress the blow transfer on the housing 1.

By adjusting the throttle 15, it is possible to reduce the impact energy to zero by flushing the filter, if necessary, without shaking.
