Abstract

Usage: water supply, operation of water wells. SUMMARY OF THE INVENTION: A cylinder with a lid in the form of a continuous membrane, on which the anvil is placed, is mounted with a clearance above the sludge collector, which is open above. A drummer in the form of a core exciter made in the form of an electromagnet periodically interacts with an anvil. At the same time, cuffs of elastic material are installed on the outer surface of the cylinder and sludge collector, the outer diameter of which is larger than the inner diameter of the filter. And the mounting device is made in the form of an elastic element. 2 s.p. f-ly, 1 ill.

WITH

The invention relates to the operation of water wells.

An object of the invention is to increase the cleaning efficiency of a water well filter.

The drawing shows a structural diagram of a device for cleaning well filters with an electromagnetic exciter.

The device for processing wells consists of a cylindrical body 1 made of magnetic material, inside of which there are coils 2, 3, a guide 4 and a hammer 5, which is capable of translating. The hammer 5 periodically interacts with the anvil 6, which is rigidly connected to the lid 7 and mounted between the housing 1 and the matching unit 16 with the possibility of axial movement. The coordination node 16 consists of two cameras - the upper 8 and

bottom 9, reinforced with a gap and attached to them by disks 10, 11, 12, 13, part of which is made in the form of a cuff of elastic material. Camera 9 was on. mono-accumulator, designed to collect sludge and other comatose particles knocked out during operation of the device.

The device is suspended on a cardboard cable or cable and power cable 14, through which the coils 2, 3 are supplied with the help of an elastic element 15. The exciter can be of another type: hydraulic, pneumatic, etc.

A device for processing well filters operates as follows.

Voltage pulses are alternately applied to coils 2, 3, and, by the action of electromagnetic force, measles 5 makes a reciprocating motion, and the reaction force acts on the housing

A device that also performs a reciprocating movement, moreover, if the core vibration frequency coincides with the natural frequency of the vibrational link (the elastic element of the suspension is a device), resonance occurs and thereby a vibrational effect is exerted on the well filter. Anchor 5, in turn, when moving downward strikes the anvil 4, which transmits the received impulse to the matching unit 15. The matching unit forms, using cuffs 10, 11, 12, 13, an active gap, directing the pulse to the well filter, while contact breaks down. Upon completion of the impact, the anvil returns to its original position, while a rarefaction is created in the active gap and the particles of colmatant are drawn into the sludge collector 9.

Thus, the simultaneous pulsed and vibrational effects on the well filter significantly increase the processing efficiency. Unlike devices such as pulsed or pneumatic explosive, in the proposed device, the regulation of pulse energy can
