Description

 The invention relates to the metallurgical, cement, flour-grinding industry and municipal services, and may also find application in agriculture on farms and vegetable gardens, in summer cottages when watering beds with vegetable stands.

 A device is known by A.S. USSR 1100358, class E 01 H 1/00 1984 for dedusting the road surface, containing a water tank with a low temperature pipe mounted on a base machine with an internal combustion engine, etc., which cannot be used in the shops of a metallurgical plant because of its large size, and the internal combustion engine will emit carbon monoxide. The piston is connected to the spool by an elastic bond, which is unreliable and short-lived. The application of the device is local, i.e. dust is suppressed where the base machine is located. The device is complex, expensive and requires highly qualified staff. The capacity of the water tank requires local refueling.

 Until now, the problem of suppressing dust on the areas of many workshops of factories and city roads, as well as cleaning the air inhaled by people, has not been sufficiently solved. The existing regulation on air purification inside the plant’s workshop does not meet hygienic requirements, gives rise to a tendency to lung diseases and needs to be changed immediately. Ecological conditions are such that they require the preservation of the natural environment.

 SUMMARY OF THE INVENTION

 To achieve dust flushing from the surface of the area, as well as from the roadway, a technical solution is proposed - a mechanical device. The use of the proposed device will significantly improve the environment inside the workshop, and on the squares and roads - the urban environment, which will improve people's health, make a significant contribution to the ecology of the environment, and clean the air. This will be the technical result of using the invention.

 The proposed device for suppressing dust on squares and roads contains a housing with a working cylinder, pipelines with nozzles with water sprinklers and a dust suppression mechanism, consisting of a spring-loaded piston with cuffs and a rod attached to it with a washer to the meniscus with the possibility of reciprocating motion, the meniscus of the washer interacts with the inner arm of the rocker arm, the outer arm of which interacts with the stem of the spring-loaded valve, on the stem of which is attached a dog interacting with tank, fastened to the hinge, wherein the process water is scattered forsunkami- vodorazbryzgivatelyami placed on the pipe, each of which is provided with a valve controlled by a spring-loaded screw nut which is mounted on the bracket, and the guide - on the outer end of the beam.

 At the same time, to wash off dust from the roadway with water spray nozzles, technical water is supplied to the spring-loaded start valve from a periodically opened and closed samovar crane, which is used by moving a moving vehicle on rotor blades mounted on a swivel roller, mounted on a samovar crane.

The device is illustrated by drawings, where
in FIG. 1 schematically shows a device (general view);
in FIG. 2 schematically shows a nozzle arrangement;
in FIG. 3 - road console (front view);
in FIG. 4 - the same (view of the assembly in arrow A).

 The device contains a working metal cylinder 1, a piston 2 with rubber cuffs 3 with the possibility of their reciprocating motion are placed in a metal housing 4. A spring-loaded metal rod 5 is attached to the piston 2 with the possibility of its movement in the guide 6. A washer 6 is fixed to the rod 5 the meniscus 8, interacting with the inner arm 9 of the rocker arm 10 with its rotation on the hinge 11. The outer arm 12 of the rocker arm 10 interacts with the stem 13 of the spring-loaded valve 14, which is connected to the pipe 15 from the samovar of tap water of 16 technical stava 17. From the starting valve 14 via an inlet 18, water is brought to the working cylinder 1. Water outlet pipe carried in conduit 19 with nozzles 20 vodorazbryzgivatelyami-established for dust suppression. At the end of the shank 21 of the rod 5, a console 22 is mounted that interacts with the rod 23, the length of which is adjustable. The lower end of the rod 23 interacts with the spring-loaded outlet 24 of the dog 25 mounted on the hinge 26. The dog 25 interacts with the dog 27. The nozzle-water spray 20 includes a valve 28 connected to the inner arm of the rocker 29, turning on the hinge 30. The inner end 31 of the rocker 29 is connected with the center of the valve 28 using the shock 32, the outer end 33 of the rocker arm 29 has a guide 34 for passing the end of the adjusting screw 35 with the washer 36 mounted thereon for supporting the spring. The nut 37 of the screw 35 is mounted on the bracket 38 of the cage 39.

Suppression on roads, highways and other lands was carried out using a road attachment consisting of a roller 40, on which rotor blades 41 are mounted. One end of the roller rotates in the bearing 42, and the other is worn on a samovar crane 16. The rotators 41 must be installed at an angle 90 ^o relative to each other at a distance of 0.8 ... 0.9 m from each other. Remote control device - the wheel of a moving vehicle.

 The operation of the device.

 Technical tap water entering the samovar faucet 16 when it is opened moves under operating pressure to the valve 14 and, compressing its spring, feeds the rod 13 upwards (according to the diagram). Water fills the piston space of cylinder 1 and moves the piston 2 up. A washer 7, mounted on the stem 5, compresses the spring, and the meniscus 8 runs onto the end of the shoulder 9, closing the valve 14. At the same time, the dogs 25 and 27 are closed. The spring of the rod 5, cocked to failure, presses on the washer 7, and the piston 2 displaces water from cylinder 1 into the pipeline 19 with nozzles 20 located around the perimeter of the site, designed for dust suppression. At zero pressure under the above-piston space, the valve 14 opens under the action of the pressure of tap water. In this case, the dogs 25 and 27 are disconnected, since the rod 23 ran onto the spring-loaded outlet 24. The valve spring 14 is compressed and the water again fills the piston space of cylinder 1, and the cycle repeats.

 The operation of the spray nozzle.

 Water entering the pipeline 19 with nozzles 20 will only open the valves 28 of the nozzles 20 and will wash off the dust when there is an overpressure in the pipeline 19. The jet is adjusted with the adjusting screw 35. When it rotates clockwise, the spring elasticity increases and valve 28 increases with more force clamped, and vice versa, for greater water flow and a large halo of the jet, it is necessary to unscrew the screw 35 at a certain angle and lock it.

 The work of the road console.

 When dust is suppressed on roads, a roller 40 with turntables 41 mounted on it is periodically rotated in the bearing 42. When the wheel of a moving vehicle runs onto the turntable blade 41, painted in blue, the crane 16 opens and the device operates automatically, periodically pouring water onto the dusty road surface . If there is no need to water the surface of the road, the driver of the vehicle bumps into the blade of the adjacent turntable, painted in red (this closes the tap 16), the device shuts down and watering stops.

 The smallest particles of dust, which is suspended in the air, will be moistened by the foggy-dispersing halo of spray water formed from dust flushing, the air will be cleaned. To improve the process of cleaning air from dust, it is advisable to add a special substance to the process water - a coagulant, which helps to improve the wetting process.

 The shirt of the working cylinder should be made of cast iron, the core of the samovar tap should be made of bronze, the cuffs should be made of rubber, the remaining parts are made of steel.

 For a stable flow of water from the nozzles, it is possible to install an electromagnet on the piston rod instead of a spring.

 The device can also find application in the irrigation of agricultural farmland, as well as beds in summer cottages.
