Description

The claimed utility model relates to the field of housing and communal services and is intended for the collection of municipal solid waste (MSW), primarily in urban areas.

Recently, in foreign practice, to solve the issue of collecting municipal solid waste in places of their mass generation in urban conditions (squares, markets, etc.), underground waste disposal systems are being used. A technical solution is known (patent for the invention No. 2043276, 6 B65F 1/00, publ. 10.09.95, Bull. No. 25) of a device for collecting waste. One of the options for the practical implementation of this solution can be considered a complex of underground disposal of solid waste from the Finnish company Ecosir Ou.

The first experience of using such a system in the Russian Federation is the Sir-Lift equipment complex (the website of Ecosir Oy is www.ecosir.com), mounted in Victory Park in Moscow.

The equipment complex consists of 3 functional blocks: a metal underground chamber, a lifting device and a removable press compactor placed in it.

The benefits of underground waste collection are as follows:

- the equipment does not take up much space, fits well into the environment, only a small loading unit is located on the surface of the earth;

- there is no problem of smell, as well as the problem of vandalism;

- The system is designed for all types of waste.

The system operates as follows.

In the underground chamber, a vertical lifting-lowering device for a removable press container is mounted, as well as a hydraulic drive for this device.

A removable empty press container, which includes a hydraulic drive unit for moving waste (press), is delivered to the underground chamber, as a rule, by an automobile multi-elevator and with its help is installed on the base (platform) of the lifting device. Then the container is lowered into the underground chamber and the press is connected to the hydraulic drive system located in the underground chamber.

Municipal solid waste is periodically fed through a loading unit located on the roof of the lifting device, from where they enter the waste compactor of the press compactor, which, in turn, cyclically feeds them directly to the container as the transfer unit is filled.

After filling the container, it is vertically moved by a lifting device to the level of the earth's surface, it is disconnected from the electric and hydraulic drive systems, after which the container is shifted and loaded with a car multi-lift for subsequent removal.

The Sir-Lift system can be considered as a prototype of the claimed utility model.

The operating experience of Sir-Lift equipment revealed a number of its shortcomings:

- low maintainability, which consists in the fact that even minor repairs to hydraulic cylinders require complete lifting and dismantling of the lifting device, which is a non-separable monoblock, including a base, racks and a roof;

- the complexity and insecurity of operation (lack of emergency lighting system, light alarm lift, emergency lift system);

- the complexity of the maintenance of underground equipment;

- inconvenient descent into the chamber for staff through a horizontal hatch, as well as leaks in the maintenance hatch of the underground part of the equipment.

The proposed new technical solution is aimed at eliminating these shortcomings, as well as improving the conditions for its operation.

The solution of the technical problem is provided by the following design solutions:

- in order to simplify the initial installation and repair of equipment, the roof of the lifting device is made of a removable structure;

- to simplify the repair of lifting hydraulic cylinders, the latter are removable and can be dismantled through special technological hatches in the roof of the lifting device, which eliminates the need to use heavy-duty cranes for their repair and significantly reduces the repair time;

- to increase the convenience and safety of operation, the complex is equipped with emergency lift, emergency lighting and alarm systems;

- the maintenance hatch of the underground part of the equipment is combined with a loading device.

Technical solutions of the claimed utility model can be implemented using tools used in general engineering. The distinguishing features reflected in the formula of the utility model are necessary for its implementation and sufficient, because provide a solution to a technical problem.

In the future, the claimed utility model is illustrated by an example of its implementation, schematically depicted in the accompanying drawings, in which:

figure 1, 2 is a General diagram of a complex of equipment, respectively, in the lowered and raised positions;

figure 3 - diagram of the site combined service hatch and boot device;

4 is a diagram of the nodes of the removable roof and the removable hydraulic cylinder.

The composition and operation of the complex are as follows.

The equipment complex (Fig. 1) consists of an underground chamber 1 installed in a prepared foundation pit in a position below ground level. To service the underground part of the equipment, a service hatch 2 is installed in the upper part of the chamber.

A lifting device is installed in the chamber, consisting of a base (platform) 3 and struts 4 rigidly fixed on it, to the upper parts of which a removable roof 5 is attached, on top of which a loading device 6 is installed. The vertical movement of the lifting device is carried out by hydraulic cylinders 7, fed from the hydraulic station 8. The lift is controlled from the remote control installed in the niche of the boot device (not shown in the figure).

Based on 3 of the lifting device, a press compactor 9 is installed, consisting of a pressing device 10 and a container 11. The MSW is supplied to the pressing device 10 of the press compactor from the ground through a loading device 6.

To ensure the safe operation of the equipment complex, the latter is equipped with an emergency autonomous hydraulic pump 12 of a known design, which is activated in the event of failure of the hydroelectric station 8 or its de-energization.

The position of the lifting device in the upper position for installing or removing the press compactor is shown in Fig.2.

To work at night, the complex is equipped with a low-voltage lighting system 13 mounted on a lifting device, as well as sound systems 14 and light alarm 15, functioning in the process of lifting the press compactor.

For fixing the press compactor on the basis of the lifting device, a locking device 16 is provided.

As an embodiment of the complex (Fig. 3), the hatch for servicing the underground part of the equipment is performed combined with a loading device installed on the roof 5, which in this case consists of a solid waste supply shaft 17 and a shaft 18 for lowering personnel into chamber 1.

To simplify the repair and maintenance of hydraulic cylinders, the latter are made in a removable design (see figure 4). To this end, the housing of the hydraulic cylinders 7 freely rest on the supports 20 mounted on the base of the underground chamber 1, and the rods 21 of the hydraulic cylinders are pivotally mounted in brackets 22, which in turn are mounted on the roof 5 of the lifting device. To dismantle the hydraulic cylinders, the brackets 22 are disconnected from the removable roof 5, hydraulic hoses (not shown in the figure) and lifted by an autonomous load-lifting device.

To simplify the initial installation of equipment, the roof 5 of the lifting device (see Fig. 4) is removable and bolted 23 to the racks 4 of the lifting device, and is also equipped with load gripping devices 24. A technological removable hatch 25 is installed on top of the bracket 22 on the roof 5.
