(54) MACHINE FOR PNEUMATIC1 CLEANING EQUIPMENT AND PREMISES

I

The invention relates to machines for cleaning equipment and premises.

A known cleaning machine for premises and equipment, comprising a trolley, a housing mounted thereon with nozzles s and a filter chamber disposed therein, a pull booster and two cyclones, connected with a pull booster via an intermediate chamber 1. .-, -. ..,, -.-..-: ..

When using such a device for cleaning equipment and rooms from fibrous material, such as fluff, the efficiency of cyclones drops sharply due to the low mass of fibrous material. In addition, it is not possible to stepwise regulate the intake and suction of air, especially necessary when

cleaning of hard-to-reach areas, which affects the quality of cleaning.

A known machine for pneumatic cleaning of equipment and premises, comprising a housing mounted on a carriage in which thrust boosters and filters are located, and nozzles connected to the body for suction and air injection 2.

This machine also does not provide good housekeeping and equipment.

The purpose of the invention is to improve the quality of cleaning.

This is achieved by the fact that the proposed machine has at least three insulated chambers: cleaning and workers, each of which is penetrated through an opening with a damper, while the filters are placed in the cleaning chamber, the boosters are tapped in the working chambers, and housed with a pipe for injecting air.

In addition, the dampers are made in the form of non-return air valves, and in each of the working chambers there are successively located several boosters, for example two.

FIG. 1 shows the proposed machine, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

Claims (3)

The machine for pneumatic cleaning of equipment and premises contains a trolley case 1 mounted on the trolley, in which the boosters 2 are placed, the filters 3 and 4 are connected to the case 1 of the nozzle 5 for air suction and the nozzle 6 for air injection. The machine has at least three isolated chambers 7, 8 and 9. Chambers 7 and 8 are working, and chamber 9 is cleaning. Each of the working chambers 7 and 8 is connected with the cleaning chamber 9, the opening 10 with the flap 11. Filters 3 and 4 are placed in chamber 9, the boosters of thrust 2 are in working chambers 7 and 8, and the outlets of the latter are connected to the pipe 6 for air injection The flaps 11 are made in the form of check valves. In each of the working chambers 7 and 8 there are several motive power boosters, for example, two. The corresponding nozzles 12 are fixed to the nozzles 5 or 6 with the help of a flexible hose 13. The machine has a braking device 14 and a drum 15 for winding an electrical cable. For manual movement, the machine is equipped with a handle 16, and for movement by means of a pull-out gear, a bracket 17. The starting electric station is located in the housing 18. The machine operates as follows. To clean technological equipment, for example, weaving machines, the machine is placed in the free passage between the station, then its position is fixed in place by the braking device 14, the flexible pipes 13 are attached to the pipes 5 or 6, and the cable is unwound. drum 15 - and connect it to the electrical network. When working for injection with a small amount of air and low pressure, they put a hose 13 with a nozzle 12 onto the nozzle b and put into operation only one booster in one of the working chambers. In order to obtain more pressure, a second mover is turned on in the same working chamber. To obtain an air jet with a large jet. the amount of air include in the work of all:. Incentives for ti gi., The need for such adjustment of the air jet arises in the process of cleaning. For example, a tucked loom with working elements of complex configuration and different resistance for the passage of the injection jet. --When working Aspirating nozzle 6 frees from the flexible hose and the latter cadets onto nozzle 5. The necessary vacuum in nozzle 12 also regulate the succession or parallel connection of the impactors of draft 2. At the same time, down and dust are sucked into the cleaning chamber 9 and settle on the inner walls filter 3, and only purified air is supplied to the boosters. In separate cases, it is possible to work simultaneously with pressure and suction, with nozzles when putting on nozzles 6 and different hoses. At the end of the work, the cable with the power supply is disconnected, wound onto the drum 15, the braking device 14 is released, and the machine is transported to another processing facility. . When the filter is filled with 3, the lid and dust are removed together with the filter and another filter or the same but cleaned one is put on its place. Thus, the device provides stepwise regulation of the vacuum and pressure of the air jet in the nozzle and hoses due to the fact that the machine has several chambers, one of which is cleansing, and the rest are working, and in each of the working chambers the thrusters can be activated separately or at the same time. In addition, each working chamber can work independently or simultaneously with the neighboring one. When alternating operation of one or the other working chamber, an additional goal is achieved - cooling the mechanisms of booster thrusters, which contributes to greater reliability in operation of fans and electric motors rotating at high speed. The elimination of air from the working chamber 7 into the chamber 8 is prevented by the flaps 11 by air check valves located in the openings 10 between the working chambers and the cleaning chamber 9. When the valve is actuated in the working chamber, the valve automatically opens the opening 10 and passes through it clean air that has been cleaned in the cleaning chamber 9. When stopping the work of thrusting in one of the working chambers, the valve closes the opening 10 connecting the working and cleaning chambers. pneumatic cleaning equipment and premises, containing installed on. a carriage housing in which traction boosters and filters are placed, and nozzles connected to the housing for suction and air injection, characterized in that, in order to improve the quality of cleaning by providing stepwise regulation of air suction and air injection, it has at least Three isolated chambers: a cleaning chamber and workers, each of which is connected with a cleaning chamber through an opening with a damper, the filters are located in the cleaning chamber, the boosters of the hygienic chambers, and the outlets of the latter are connected with chopping. air charging. 2. The machine according to claim 1, wherein the dampers are designed as non-return air valves. 3. Machine on PP. I. and 2, characterized in that in each of the working chambers there is a series of cranes, for example two, located successively. Sources of information taken into account in the examination 1.
