Abstract

Pshpina for cleaning drainage wells from solid sediment can be used for sanitary cleaning of cities. The chain of the invention is to increase labor productivity by reducing the time to empty cis; are terrible. The machine contains a hook-on chassis 1, on which you install pressure-discharge piping 2, a vacuum pump 3, a distributing air outlet 4, a winding drum 5, an air nozzle 6, a tank 7, a drain window 10, and the rotary fittings P, end nozzles 12 with screw nozzles. The machine works as follows. An air nozzle 6 is lowered into a drainage well and air is supplied from a vacuum pump 3, which causes solid particles to be suspended, while vacuum 7 is created in the tank 7 and the solution is sucked into the tank until it is completely filled. Then the air is fed into the pressure-discharge piping; 2, and the Cwreze ilorethier flare inserts 11 and the end nozzle 12, the air enters the tank of the tank 7 and leads into the fluid and together with it the crumbled solid residue.

Description

And-; the invention relates to the rural nursery and pepioma and the commercial machine, it is particularly for sanitation machines of the city, and is an improvement of the invention according to the author. St. № 12014АЗ.

The goal is to increase labor productivity by shortening (time spent on emptying. Tanks.

Figure 1 shows a machine for cleaning drainage wells from solid sediment5 common in: the rear; FIG. 2 shows the kinematic scheme of the operation of the downstream aeration system; fig.z - iloaeric bell insert; Fig, 4 - end cap.

The machine contains a towing chassis 1, on which pressure pipes 2, a vacuum pump 3, an air distribution unit 4, a winding drum 5, an air nozzle 6, a tank 7, a viewing hatch 8, a lifting mechanism: m 9 well covers, are mounted - drain window 10 ,, nloaeririruyuschie rass-. inserts 11, end nozzles 12, suction air pipe 13, purge pipe 1A, tractor. 15, gate valve 165 inlet pipe 17, air 18 and spiral-shaped. 19 nozzles.

The machine works as follows.

The machine drives up to the cleaned drainage well, lifting mechanism 9 removes the cover of the well, into which it lowers the air cell 6, connected by a hose through the winding drum 5 with the dispensing unit 4, into which air is supplied from the vacuum pump 3. Simultaneously a vacuum is created in tank 7. After the solution has been created in the well, Go is opened uniformly on the suction pipe 13 and the solution is sucked into the tank 7 until it is completely filled. After that, the valve 16 is switched to the air supply from the vacuum pump 3 through the supply pipe 17 to the pressurized pressure pipe 2 mounted in the bottom of the tank 7.

If the pipeline is strung, it becomes loose with muddy scaffolds, open the rear of the 16 n purging port.

cabin 14 and the entire system is flushed. After the lero, the valve 16 is closed and the air through the pressure-discharge pipelines 2 enters the aeroelectric sockets 11 and the end nozzle 12 and through the nozzles 18 and 19 into the tank 7, drives the fluid and together with it compressed solid residue. The directionality of the holes of the nozzles 11 and KOHueBbFX nozzles 12 in one direction contributes to the unwinding of all the liquid in the container in a vertical plane, which leads to the effective shaking of the entire dense mass of the compacted particles. After this, the spillway window 10 opens and the homogeneous mass prepared under pressure is poured from the tank 7. In the most stressed part of the spillway hole, end plugs 12 form a vortex-like movement, facilitating better emptying of the container.

Such a constructive execution of the machine improves the reliability of the preparation of a homogeneous solution with a full lift of all packed residue, which significantly improves the operating conditions and reduces manual labor costs by 30–40%, reduces the time when unloading sludge from the tank by 5 times,
