Description

The invention relates to a technique for treating oil-containing wastewater, in particular, to devices for pneumatic cleaning of sewage disposal plants for washing plants, mainly used for washing cars, ashtobuses, etc.

A device for pneumatic cleaning of a soil drainage tank is known, comprising a soil drainage tank communicating through a valve with a tank for collecting sludge connected with pipelines with a source of compressed air and a loading hopper installed above floor level 1.

However, the device has insufficient reliability and low efficiency in operation. This is due to the fact that in order to dilute the packed sediment to the tanks, the water supply pipe is connected, which breaks the tightness of the tank, and dilution of the sediment leads to poor efficiency, as the feed silo enters the liquid sludge unsuitable for loading into a dump truck body, and its additional sludge dewatering is required.

In addition, in the known device, the valve of the tank is made with

by an electric drive under severe operating conditions - constant dampness, as a result of which the electric motor often fails.

The purpose of the invention is to increase efficiency in operation and operational reliability.

This goal is achieved by the fact that, in an installation containing a grinder, the servicemen, communicating tanks for collecting sludge with a receiving neck and a bolt, a loading hopper, compressed air pipelines, supplying wastewater Ji cleared, tanks are installed in a row, sequentially, and the soil drainage pans are made in the form of communicating, installed on the receiving neck, reservoirs of rectangular funnels, connected in the upper part between each other by branch pipes and with pipelines for the supply of sewage and discharge of water At the same time, inside the funnels, at the level of the upper edge, they are attached to their

25 side walls of several different height shields - suspended particles, with a gap between them and the base of the funnels, the greatest in the first of them relative to the direction

30 is the lowest in the sewage flow, and the valve is designed as a locking disc valve mounted with hinges on the receiving mouth of the tank with a drive through a rod hinged to it with a handle at its free end and a retainer. Figure 1 shows the installation of pneumatic cleaning of the soil drain trap, longitudinal section; in fig. 2 - the same plan view; in fig. 3 shows the node I in FIG. 1. Installation of pneumatic cleaning of soil debris washing devices, for example, in automobile transport enterprises contains several sealed reservoirs 1 mounted in one row for collecting sludge received from soil dewatering towers made also installed in a row on the receiving mouths of rectangular tanks 1 communicating funnels 2 connected in the upper part between each other by branch pipes 3 and with sewage supply pipelines 4 and. Drainage of 5 separated water. Inside the thieves are blocked by several shields of separators b preventing the free movement of suspended particles of sewage. The pins 6 are fastened at the level of the upper edges of the funnels to their side openings perpendicular to the pipelines and are made with different height dimensions that do not reach the base of the funnels and form the gap with them, the largest at the first cutter, considered in the direction of flow and the least - the last. Each tank 1 is supplied via pipeline 7 with compressed air, which is used to empty the tank 1 through pipe 8 attached to the bottom of the tank 1, the free end of pipe 8 is placed above the hopper 9 installed above the floor, with the possibility of filing under his auto dump (not shown). providing the necessary sealing of tank 1 when empty. From it, there is a locking disc valve 10 fixed by means of hinges, for example loops 1D, to the neck on the inner sides of the tank 1. The valve is controlled by means of a thrust 12, hinged to the eyelet 13 of the valve U and having a handle on the free end tku 14 and lock 15.. The installation works as follows. First of all, the valve 10 is closed by means of the thrust 12 and fixed in the secured position by the latch 15, thereby ensuring complete sealing of the tank 1, then the valve (not shown) of compressed air supply through the pipeline 7 to the cavity of the tank 1 filled determined by any of the known level gauges. After that, under the pressure of 3–4 ati, generated by compressed air, the sludge of any cavity, i.e. The packed, dehydrated, is pushed out of the pipe 8, water 8 into the bunker 9, from which it is discharged into the body of the dump truck. When the tank is empty, the compressed air supply is shut off and the shut-off valve opens, the process ends and the tank is ready to receive sludge. The proposed device for pneumatic cleaning of the soil drainage pans of the washing installation is characterized by efficiency and operational reliability. Claim 1, Installation of pneumatic cleaning of soil debris tanks containing land debris tanks, communicating with them to collect sludge from the receiving neck and valve mounted on it, loading hopper installed above the soil dewatering pipes, wastewater supply pipelines and drained clarified water, compressed air pipelines characterized in that, in order to increase efficiency in operation and operational reliability, the tanks are installed in series in series, and the ground debris is made in the form of ennyh throats for receiving tanks rectangular closed on top with vertical shields funnels Shutoff E r wherein c zeotstoyniki reported in series between a supply conduits of wastewater, and the height-shields stripper and the distance between them increases monotonically in the direction of flow of treated water. 2. Installation under item 1, characterized in that the valve is made in the form of a locking dish-shaped valve with loops fixed to the reservoir throat by a drive, pivotally connected to it with a pull, a handle and a lock.
