Description

The present invention relates to an industrial vacuum cleaner for absorption

  of dust, debris and liquids, comprising a suction system driven by motor, connected to a receptacle for at least dust and liquids and provided with a

  engine tuning and starting equipment.

  On already known vacuum cleaners of this type, the suction fan which generates the vacuum is driven by a motor.

  electric powered by mains, so that these devices

  reils present a cable for connection to the network. Their industrial use, cleaning of large areas for example

  such as sports centers, residential complexes, workshops

  liers etc .... therefore requires cables of a very long length, 50 m most often or more. The use of these

  devices is far from being facilitated by such lengths.

  The same drawback appears with shorter cables

  which must be reconnected frequently, the.local to be cleaned -from-

  before having a relatively large number of

  taken. The cleaning work carried out with these devices

  reils, therefore in all cases require considerable time

  corn. To avoid any risk of deterioration,

  also handle the connection cable with care

  difficult to meet with staff

  often changing auxiliary. With industrial vacuum cleaners

  three already known, the absorption of residual rainwater

  on tennis courts for example, after a rain of

  brief but abundant summer rabies, requires particularly high labor, duration and cost; the accumulation of energy required for the engine is indeed expensive, the purchase and maintenance of this reserve, represented by

  rechargeable batteries, being also very expensive.

  As the batteries are very heavy, transport and handling

  ment of already known industrial vacuum cleaners is particularly

long and inconvenient.

  The present invention aims to create an industrial vacuum cleaner of the type described above, characterized by a very high suction power on the one hand, usable easily, quickly and at any time with unlimited mobility in

space on the other hand.

  According to an essential characteristic of the invention, the

  engine, consisting of a portable internal combustion engine

  small and compact, shaped with the fan of the

  suction system, a fuel tank, a disposi-

  ignition and a relief valve, a single component mounted on a common support which covers a

opening of the receiving tank.

  The suction fan of the device according to the invention is driven by an internal combustion engine; the latter, the aforementioned fan and other elements of the vacuum cleaner are mounted on a common support which rests on the receiving tank. As this configuration makes any electrical connection cable redundant, the industrial vacuum cleaner can be moved in any way when cleaning premises and large areas, without its freedom of movement being hampered or hampered by the presence of a connection cable. Since it is useless to pay attention to the cable or reconnect it to move the device, cleaning work is greatly facilitated and carried out in essentially reduced time. he

  the result is a significant saving of money.

  The internal combustion engine according to the invention pre-

  also feels the following advantage: at equal power, its form of construction, and therefore its weight, are reduced by

  compared to that of an electric motor, so that the trans-

  port and handling of the vacuum cleaner are considerably facilitated. The power of the combustion engine is also

  unlimited, while that of an electric motor runs

  tionnant in alternative cannot generally exceed

  2000 W. Any risk of short circuit on wet ground is

  end avoided. This small combustion engine, light but powerful, being mounted on the support with the suction fan and

  other parts of the device, forming a system of

  complete piracy and in working order, it can have a universal use. It can be assembled with

  the most diverse receptacles, to constitute aspira-

  industrial producers of any size and shape. The receptacle can be small and pot-shaped for example, the vacuum cleaner can be easily handled by one person. It is also possible to use a bin

  large and long receiver, mounted on a vehicle.

  In a preferred form of construction of the invention

  tion, the internal combustion engine is an

magician by spark.

  In another preferred version, the combustion engine

internal tion is a Diesel engine.

  In a third advantageous form of construction, the internal combustion engine is represented by an engine with

liquefied gas.

  On the vacuum cleaner according to the invention, in which the

  extractor fan is connected to a transmission, a

  sure judicious lies in the assembly of the latter on

the support.

  Another judicious measure is represented by the ring

  profile provided on the circular support, to which it

  fère a waterproof support on a rim of the opening of the receptacle. Another advantage of the present invention is that the profiled ring is formed by a shoulder-shaped rim

protruding from one side of the support.

  A particularly advantageous measure lies in an ele-

  ring-shaped seal, mounted inside

the profiled ring.

  In a preferred form of construction of the invention

  tion, the support has at least a quick closure, preferably four in the form of hooks and distributed at a

  equal peripheral distance, this measurement making it possible to obtain

  nir a removable assembly of the support and the receiving tank.

  A final advantage is finally that the support has a

  handle at least, two preferably diametrically opposite

  sées. The invention will be better understood using an example of

  construction illustrated in the appended drawings, which represent

  tent: Figure 1: a partial section of an industrial vacuum cleaner

  according to the invention, with a vacuum system

  with engine in working order and mounted on a

  horizontal receiving tank, partially shown

  tee, Figure 2: a top view of the industrial vacuum cleaner of Figure 1, Figure 3: the motor vacuum system of Figure 1, mounted on a vertical tank, Figure 4: the motor vacuum system in Figure 1 with a receptacle attached to a vehicle. FIGS. 1 to 4 represent a suction system with an engine 1 with a support 2, on which are mounted an internal combustion engine 3 equipped with a fuel tank 4,

  a suction fan 5 and a transmission 6. The available

  auxiliary devices known per se (not shown), such as a starter, igniters, adjustment and control equipment, essential for the functioning of the suction system, are also fixed on the support 2. The latter is preferably represented by a circular disc (Figure 2), with a peripheral rim 8 in the form of a shoulder outwards and bent downwards. This rim constitutes a profiled ring 8a which has an L-shaped section, protrudes from the face 7 of the support 2 opposite the suction system 1 and fits hermetically on a vertical rim 9, projecting upwards, from an opening. 10 of a receiving tank

  11. In order to compensate for any manufacturing tolerances

  tion and ensuring a hermetic assembly between the support 2 and the opening 10, an elastic sealing ring 12,

  mounted inside the profiled ring 8a, is essential

  partially embedded between the latter and a ring

  dull radial 8 '. To get a fixed assembly, but

  easily removable at any time between the vacuum system

  motor ration 1 and the receiving tank 11, ld periphery of the support 2 preferably has four quick fasteners 13, 13 'to 13 "', distributed at equal diatance from each other and provided with pivoting hooks 21, which s '' engage in counter-closing elements 14 fixed on the upper face 18 of the receiving tank 11. In order to prevent the liquid absorbed and collected in the tank II from entering the suction system with motor 1, a valve safety 15 known per se, mounted in the support 2, acts as a relief valve Transport and handling of the industrial vacuum cleaner are facilitated by two diametrically opposed handles 16, 16 '(figure 2), provided on the profiled ring 8, preferably on the vertical rim 8a. As a result of its compactness, the suction system 1 can have universal use and extreme profitability.

  receiver required in each case is simple and fast.

  To suck rainwater on tennis courts, it is for example possible to mount the motorized suction system 1 on a vertical receiving tank 11 (Figure 3), to which it is hermetically fixed using quick-release closures 13, 13 '. The movement of the container 11 can be facilitated by rollers.

  In the construction form of FIG. 4, the receptacle

  11 ′, bulky, is mounted on a sled 19 which can be combined with a towing vehicle (not shown). The tank it 'has a tube 22, the rim of which engages in the profiled ring 8 of the suction system 1 and comprises

  the counter-closing elements 14, provided for the hooks

  chets 21 quick closings. System 1 is fixed on

  the tubing 22 as previously described.

  The receiving tanks 11, 11 ′ are fitted with a connection tube 23, 23 ′ to a flexible hose (not shown), the free end of which is provided with a nozzle for suction.

  dust, debris or liquids on the surface to be cleaned

  yer. The vacuum is generated by the suction fan

  5, which the internal combustion engine 3 drives by the

  intermediate of the transmission 6. The latter has a return shaft 24 which supports at its two ends an intermediate pinion 25, 26. By means of a continuous transmission, by chain, belt or cable for example, the lower pinion is connected to a pinion leading 28 from a tree

  combustion engine engine 3. The advantage of a trans-

  belt or cable mission lies in a stability of

  high walking and low noise.
