Abstract

A heat gun for the cleaning and heat treatment of surfaces, joints, cracks and the like by the use of a hot blast jet produced by the exhaust jet of a jet engine, where aggregate injectors have been added in the engine jacket for the admixture of a cleaning medium, such as sand, granulate material or liquid. A heat gun according to figure A exhibits a lightweight jet engine arranged under an engine jacket 2, with an aggregate injector, which is capable of dosing a cleaning medium admitted into the hot exhaust jet, which is discharged through an exhaust nozzle 1 directed at the item to be treated. The engine is controlled electronically by a device 4 and is advanced on a lightweight frame 5, which may be fitted with a ballast weight 9 and spacer wheels 10, or be mounted on an advancing arrangement 8. The jet engine is powered by liquid fuel supplied from a tank 6. Intake air is cleaned and sound-damped in a filter unit 3, and the combustion takes place at a high pressure and is discharged hot and in a high velocity exhaust jet, to which cleaning media fed from a tank 7 are added.

Description

Heating and cleaning apparatus for surface treatment
The invention relates to an apparatus for heating and cleaning of items, surfaces, joints and similar where the intention is to remove weathering, wear and dirt or added coating. This is achieved in accordance with the invention by using a lightweight jet engine with a special engine housing to which has been added an aggregate injector that can dose aggregate materials into the exhaust jet, which thereby cleans and dries the blasted area while being advanced manually or by self-propulsion.
Mutually independent systems are often used in the methods known today. First, the area is cleaned by the use of a high-pressure system with air or water directly or with aggregate cleaning agents, such as, by way of example, sand, which are subsequently heat- treated with gas burners with a naked or indirect flame. In
principle, the known technique has the requisite characteristics, but it is inexpedient to first employ heavyweight high-pressure systems powered by diesel or petrol engines, which discharge large quantities of heat directly into the environment through their exhaust and cooling systems and to then employ a second source of energy for subsequent heat-treatment by gas burners supplied with propane from pressurised cylinder systems. These systems involve the disadvantage of handling and transporting "hazardous goods" and also constitute a serious security problem due to the risk of terrorism that has now led to the imposition of severe security requirements and restrictions on their use at mobile workplaces which use and store gas in pressurised cylinders and tanks.
It is known from patent publication Dl GB614725A that by employing a blast of hot exhaust air generated by a jet engine's exhaust, which, after being discharged through a pipe and hose system, is admitted to a work area where a dosing device for the admixture of sand or similar has been added to an exhaust nozzle for cleaning by
sandblasting can thereby be obtained.
In the case of the invention mentioned by way of introduction, an effective tool is provided for cleaning and heat-treatment in one operation, wherein the disadvantages of the known technique are remedied. This is achieved by use of a lightweight jet engine in which a liquid fuel, such as, by way of example, petrol or diesel oil, is injected under electronic control into a compressed
combustion chamber out of which the exhaust air is discharged from the engine housing by way of an aggregate injector for sand or similar cleaning medium, which is dosed and discharged through one or more nozzles to the area to be cleaned. The jet engine sucks in air through a filter unit that can be mounted directly on and around the engine unit, or disposed at a distance from the cleaning area, supplying the air through a flexible supporting structure. The exhaust nozzle can be adapted for various tasks: it can, by way of example, be elaborated as a narrow and long nozzle, for deep treatment of joints and cracks, or as a wide and short nozzle for treating large surfaces. When the exhaust jet is pointed at an item, the exhaust nozzle will be subjected to a counterforce that will attempt to press the nozzle away from the item. For this reason it may be expedient to use a ballast weight and spacer wheels for easy advance and for maintaining a suitable distance between the nozzle and item. A heating and cleaning apparatus in accordance with this invention can be executed for simple manual operation mounted on a lightweight frame or trolley, or two or more devices can be mounted together on a self-propelled manned or remote-controlled advancing arrangement .
The invention is further explained below with reference to a drawing in which:
Figure A illustrates a device in accordance with the invention for simple operation, with fuel and aggregate conveyed with it in a lightweight arrangement, where said fuel and aggregate are admitted through hose connections .
Figure B illustrates multiple devices mounted in an arrangement that can advanced remotely or be connected to a manned self-propelled vehicle.
In Figure A, an apparatus is seen with a lightweight jet engine mounted under an engine housing (2) , with an aggregate injector for admitting the cleaning medium into the hot exhaust jet which is discharged through a blast nozzle (1) . The intake air is led through an air-and-noise filter unit (3) , and the jet engine is here controlled by control device disposed in the handle (4) . Everything is here mounted on a simple mobile frame with an armrest (5) , where the fuel tank. (6) and aggregate container (7) are conveyed with it on a lightweight trolley (8) . The apparatus for heating and cleaning is illustrated here fitted with a ballast weight (9) and load- relieving and spacer wheels (10) .
In Figure B, a second embodiment of a apparatus for heating and cleaning is seen, with multiple engine units (2), with blast nozzles (1) and an intake filter (3), here mounted in an advancing
arrangement (8) which can carry with it fuel (6) and aggregate materials (7) and be advanced and controlled from a self-propelled manned or remote-controlled unit.
