(54) DEVICE FOR MECHANICAL WATER PURIFICATION

12

The invention relates to the purification of water coming from open water

Sources to RAIN and WATERING

machines designed for irrigation.

A device for mechanical purification of water is known, comprising a frame, an inclined grate, a drum with a lead and a traction cable and cleaning, a working member made in the form of a tine, which is hingedly attached to the lifting and lowering carriage Cl, which changes in the guides.

However, this device is inconvenient in operation and has insufficient bandwidth.

Closest to the present invention is a device for the mechanical purification of water, comprising a housing, a grill, a paddle wheel with an axle, connected by a chain drive to a conveyor shaft with brushes fixed on it and scrapers 12}.

A disadvantage of the known device is its low throughput.

The purpose of the invention is to increase the capacity of the device.

The goal is achieved by the fact that the device for mechanical

25 impeller 4 with axis 5 mounted in slots 6 of housing 1. On axis 5, an asterisk 7 is rigidly fixed, which by means of a chain gear 8 is connected to an asterisk 9 fixed to the driven shaft 10 of a chain conveyor 11, which has spans 12 and 13 and sprockets 14-17 and 18, 19 and equipped with scrapers 20 and brushes 21. The blade wheel axis 5 and the chain conveyor shaft 10 are interconnected by strips 22, with the strips attached to the shaft 10 for rotation. A pulley 23 is rigidly fixed on the shaft 10 and connected by means of a belt 24 to a pulley 25 mounted on the auger shaft 26. The device has a mechanism for raising and lowering the impeller, which includes rods 27 and 28, which are hinged to the slats 22 by one end and by means of toothed racks 29 and 30 are kinematically connected with gears 3 and 32, fixed on the top 33, which has a handle 34. To install the paddle wheel in a certain position, the mechanism has a retainer consisting of a ratchet wheel 35 mounted on the shaft 36 and 37 dogs, set ennoy n rail 30. The apparatus operates as follows The apparatus is installed in a special camera head portion kana or directly into the tray. Work em it due to a water drop of 10 20 cm in front of the paddle wheel and behind it. The flow of water, the passage through the grid 2, leaves trash on it and, falling on the impeller 4, drives it in rotation. The wheel, in its turn, through the chain drive 8 and the driven shaft 10 drives the chain conveyor 11, as a result of which the scrapers 20 and brushes .21, moving from bottom to top on the surface of the grid, collect the settled debris and move it to the upper part of the conveyor, from where the garbage enters the receiving tray of the auger 26. At the same time, the rotation of the driven shaft 10 is transmitted by means of a V-belt transmission to the shaft of the auger 26, which moves the incoming garbage into the receiving hopper overboard the canal or tray. When skipping through the channel of maximum water flow, it is necessary to move the impeller 4 with the axis 5 along slot 6 to the upper position by rotating the handle 34 through the gear-rack drive. The dog 37 of the ratchet wheel 35 will lock the impeller in the desired position. Due to the lifting of the impeller, the proposed device is used on irrigators with different irrigation water consumption. The annual economic effect of its use is more than 14 rubles per hectare. 1. Device for mechanical cleaning of water, comprising a housing, a grill, a impeller with an axis connected by a chain drive to a conveyor shaft with brushes and scrapers fixed on it, characterized in that, in order to increase the capacity of the device, equipped with a mechanism for raising and lowering of the impeller, including the strips, one end of which is connected to the conveyor shaft, and the other end is connected to the axis of the impeller pivotally connected to the slats, with the toothed racks attached at the ends An atomic wheel that engages with the rack teeth, a retainer and a screw with a V-belt drive connecting it to the conveyor shaft, while the casing is made with a groove in which the impeller axis is located, 2. The POP.1 device, characterized by that the retainer is designed as a ratchet mechanism. Sources of information taken into account during the examination 1. USSR author's certificate 622922, cl.
