Стоимость одного фильтра меньше стоимости прототипа более, чем в 2 раза.The automatic mesh filter is characterized by simplicity of design, high reliability and does not require additional energy to ensure operability, in addition to the energy of the falling liquid stream, it does not require any scarce materials, it is accessible to small workshops in the manufacture, the purified liquid chamber is completely protected from the ingress of the original dirty liquid . The cost of one filter is less than the cost of the prototype more than 2 times.

Claims

The invention relates to filtering, in particular to screen filters, and can be used to clean all kinds of liquids, such as wastewater from livestock breeding complexes, from coarse suspended and floating impurities, as well as in water supply, subsurface irrigation, environmental protection systems. environment, and in chemical production. A strainer is known, including a mesh inlet chamber, a chamber of purified liquid supplying, discharging and sludge pipes and a drive. The disadvantage of this filter is the low reliability, complexity of the design and the need for additional energy to ensure its operability. a filter including a mesh, an inlet chamber, a hinge, a chamber of purified liquid and a feed, discharge and sludge pipes 2. The disadvantages of the known filter are the complexity of the design and the juicing the need for work to provide seals at the inlet of the mesh chamber and the presence of special elements for washing the ax, as well as the need to bring 1 | additional energy to ensure its efficiency. The purpose of the invention is to increase the reliability of the design and reduce energy consumption. The goal is achieved by the fact that in a filter containing a mesh inlet chamber: a measure installed on a hinge, a collection chamber 11p of purified liquid, supplying, discharging and sludge pipes, the inlet chamber is made in the form of a trough of an evenly balanced triangular profile with a lower edge long sides and located above the chamber for collecting the purified liquid, while the hinge is placed on the lower edge of the trough, and the supply pipe is directed to the short cToiioHy trough by the outlet. The trough is provided with a magnetic lock of the horizontal position, a tipping over limiter and vacuums attached to the inner surface of the trough. The drawing shows the automatic filter screen, a general view. The filter contains a mesh inlet chamber 1 in the form of a triangular profile trough with a hinge 2 on its lower edge, a chamber for receiving the purified liquid 3, a supply pipe 4 with an outlet under the short side of the trough profile, a discharge pipe 5, a slurry pipe 6, a magnetic fixator 7 horizontal position of the inlet chamber, tilting limiter; 8 of the inlet chamber and vacuum tube 9 In the initial position of the grid chamber (trough) 1 does not contain sediment and is fixed in horizontal position by a magnetic latch 7. Work filter is as follows Gy zna fidkst supplied through the pipe 4 and into the jet falls setchatun) camera 1 at its short side. During the fixation of the liquid through the network, sediment accumulates from previously suspended substances on it, and the cleaned liquid enters the downstream liquid collection chamber 3, as a result of accumulation of sediment in the chamber, which focuses mainly on the elongated, side profile - trough, up to a certain weight value, the force of the magnetic latch 7 becomes insufficient to keep the trough in a horizontal position. It tilts and limiter 8 holds it in such a position that the dirty fluid from pipe 4 continues to fall on the short side of the trough profile, and in the trough there will be a flush liquid flow directed by B to the slurry pipe 6. The sediment is dumped with dirty liquid sludge pipe 6 down the drain. After flushing the bent, the elongated side of the coil profile returns to its original weight and under the action of a falling jet of liquid on the short side of the trough profile is rotated around the hinge 2 in a horizontal position and fixed by a magnetic retainer 7, The liquid cleaner is discharged through the pipe 5 creating a vacuum flow through the grid behind each rail, which helps to extract (suck out) sediment particles stuck in the grid cells. Each rail can have a different lateral profile close to the direct triangle. Reiki secured with a certain step. An automatic screen filter is characterized by simplicity of design, high reliability and does not require additional energy to ensure operability, except for the energy of a falling jet of liquid, does not require any deficient materials, is available in manufacturing by a small workshop, the chamber of the purified liquid is completely protected from penetration of the original the heat of the liquid. The cost of one filter is less than the cost of the prototype more than 2 times. Claims 1 .. An automatic fluid screen filter containing a mesh inlet chamber mounted on a hinge, a chamber for collecting purified fluid supplying, discharging, and sludge tubing, characterized in that in order to increase the reliability of the design and reduce the cost of energy. The inlet chamber is made in the form of a trough of non-equilateral triangular profile with an edge at the junction of the short and long sides and is installed above the chamber to collect the purified liquid, while the hinge is placed on the lower edge of the trough, and the supply pipe the outlet is directed to the short side of the trough. 2. The filter according to claim 1, characterized in that the trough is provided with a magnetic lock of the horizontal position, a tilt limiter and avkum-strips attached to the inner surface of the trough.
