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. An example of such a system is the Sir-Lift equipment complex (manufacturer Finnish company Ecosir Oy, website www.ecosir.com).

The equipment complex consists of 2 functional blocks: a metal underground chamber and a removable press container (compactor) placed in it.

The advantages of underground disposal, and in fact temporary storage of waste, are as follows:

- 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;

- installation of the system is simple and does not take much time.

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 it is installed on the platform of the device for lifting and lowering the container vertically. After that, the container is lowered into the underground chamber and the press is connected to the hydraulic drive system and the electrical system located in the underground chamber.

Municipal solid waste is periodically fed through a loading unit located on the surface of the earth, from where it enters the waste transfer unit (press), which, in turn, cyclically delivers it directly to the container as the transfer unit is filled.

After filling the container, it moves vertically to the level of the earth's surface, it is disconnected from the electric and hydraulic drive systems, after which it is shifted and loaded with an automobile multi-lift for subsequent export.

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

Sir-Lift equipment has several drawbacks.

1. An integral part of the removable container is the waste feeder (press), which occupies at least 30% of the length of this unit. In this regard, the possible useful volume of waste collection and transportation is reduced, which is extremely rational. In large cities, the transport component of the costs of collecting solid waste is predominant, and therefore, increasing the volume of containers, all other things being equal, is an urgent task.

2. The device (press) for feeding waste into the container is located at the bottom of the container, which does not provide a degree of filling of the container of more than 70%.

3. The complex of equipment does not provide separate collection of municipal solid waste.

4. When installing and removing the container, it is necessary to connect (disconnect) it with the power grid and hydroelectric station.

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:

- for a relative increase in the useful volume of the removable container, the waste transfer device is made in the form of a separate unit permanently installed in the underground chamber and is equipped with an adapter for connecting to the removable container. At the same time, there is no need for a permanent connection (separation) of the container with the power grid and hydroelectric station;

- to increase the degree of filling of the container, the waste transfer device is located in the upper part of the underground chamber with an angle to the container, and is also equipped with a system for controlling its filling with waste, which, in turn, is connected to the drive system of the waste transfer device;

- to improve operating conditions, the device for vertical lifting-lowering the container is equipped with a hydraulic drive with remote radio control;

- as an embodiment, the loading unit, the waste transfer device and the container are made in a sectional

performance and provide separate collection of at least 3 types of municipal solid waste (MSW).

The technical features 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 is a General diagram of a complex of equipment (the container is shown in the position lowered into the chamber);

figure 2 - diagram of a device for moving waste;

figure 3 is a top view of the waste transfer device;

4 is a diagram of a three-section container.

The equipment complex (Fig. 1) consists of an underground chamber 1 installed in a prepared foundation pit in a position below ground level. To receive solid waste on the roof of the chamber, a loading device 2 is installed, from which the waste enters the transfer device 3, which ensures their cyclic supply by the command of the fill sensor 4 using the hydraulic drive pusher 5 to a removable container 6. The transfer device 3 is mounted in the upper part of the underground chamber to provide supply of solid waste to the top of the container. The waste transfer device 3 is connected to the container 6 using a hydraulically driven mobile adapter 7. The removable container 6 is mounted on a vertical lifting-lowering device, which is a rigid spatial structure consisting of a base 8, vertical racks 9 and a roof 10. The device is raised and lowered using hydraulic cylinders 11, based on the bottom of the underground chamber 1.

The hydraulic cylinders 11 of the lifting-lowering device are driven by a hydraulic station 12 installed in the underground chamber 1, and a control system consisting of a control unit 13, also installed in the underground chamber, and a remote hand-held remote control 14.

The drive of the pusher 5 of the waste transfer device is also carried out from the hydraulic station in automatic mode by the command of the fill sensor 4.

The scheme of the device for moving waste 3 is presented in figure 2 and figure 3 (top view). The device consists of a housing 15, inclined mounted on the bracket 16 of the underground chamber 1. Inside the housing, a U-shaped pusher 5 is made in the form of a hollow box structure, driven by hydraulic cylinders 17 installed inside the pusher box.

The housing of the moving device is connected to the loading hatch 21 of the container (Fig. 4) through a movable adapter 7. The adapter is driven by a hydraulic cylinder 18.

A variant of the complex is possible to ensure separate collection of solid waste (paper packaging waste, polymeric materials, glass, aluminum cans). Figure 4 presents a diagram of a variant of a 3-section container for collecting three types of waste. In this case, the standard container is retrofitted with partitions 19, and the front door is replaced with three doors 20 (according to the number of compartments), and opening loading hatches 21 are equipped in the upper parts of the doors to receive certain types of solid waste. In addition, a 3-section loading device 2 and a pusher of the moving device 3 are also performed, and the number of adapters 7 corresponds to the number of sections of the container. Three sectional execution of these nodes is conditionally not shown.

Works complex equipment as follows.

An empty removable container 6 is delivered to the underground chamber 1 by an automobile multi-lift of a known design (not shown conventionally).

Using the remote control 14 carry out a vertical upward movement of the lifting device to align the base 8 with the ground level.

A multi-lift removes the container and pushes it onto the base 8. The loading hatches 21 of the container are opened, and then the container is lowered into the underground chamber.

Using the hydraulic cylinder 18, the adapter is moved to connect the waste transfer unit with the loading hatches of the container.

MSW periodically fall asleep in the boot device 2, from which they fall into the housing of the displacement unit. When the housing is filled with waste, the sensors 4 give the command to the control unit 13 to cyclically turn on the hydraulic cylinders 17 for moving the pusher 5, which shifts (moves) the waste into the container 6. After filling the container with waste, the adapters are withdrawn and the container is lifted to the ground for its removal multi-lift.
