Description

  The present invention relates to a vacuum cleaner, and more particularly, to a compressed air-actuated composite vacuum cleaner that can quickly discharge various foreign substances in a storage tank.

  A conventionally known vacuum cleaner drives a fan connected to a shaft of a drive motor provided in a sealed case of an electrically operated vacuum cleaner to reduce the internal pressure of the case to a lower pressure than the outside. While the pressure is reduced, dust is sucked from the outside using the reduced internal pressure of the case and is filtered by a filter provided in the case.

  However, such a conventional vacuum cleaner frequently breaks down during long-term use and generates a large noise. Also, when it rains, water is discharged from the shipbuilding blocks (part of the hull) stacked in the shipyard. When used to discharge water, there is a great risk of electric shock, and since the failure rate at the time of flooding is high, it is not practically commercialized.

  For this reason, recently, vacuum cleaners have been developed that use the ejector principle to collect various foreign substances with high-pressure compressed air. That is, the vacuum cleaner using compressed air forms a vacuum inside the main body according to the ejector principle, and sucks and collects foreign matters such as chips, dust and fluid in the storage tank.

  However, since such a conventional vacuum cleaner has a drain unit for removing various foreign substances arranged at the upper part of the storage tank, it is necessary to clean it in order to discharge the collected foreign substances from the storage tank. It was necessary to interrupt the operation of the machine and tilt the storage tank 90 degrees or more. Therefore, in such a conventional vacuum cleaner, the discharge process becomes troublesome for the operator and the discharge speed is slow, so that cleaning work is delayed, and various foreign substances can be completely removed from the storage tank. There was a bug that it was not possible.

  Therefore, the present invention is directed to a compressed air actuated composite vacuum cleaner that can substantially eliminate one or more problems due to limitations and disadvantages of the prior art.

  An object of the present invention is to provide a compressed air-operated vacuum cleaner capable of instantaneously and quickly discharging various foreign substances collected inside a storage tank.

  Another object of the present invention is to provide a compressed air-operated vacuum cleaner that can be easily moved.

To achieve these and other advantages and objectives of the present invention, a compressed air actuated vacuum cleaner is provided, as embodied and broadly described.

  Referring to FIG. 1, the ejector 10 evacuates the storage tank 32. The ejector 10 is connected to a pipe. This pipe is provided with a valve 12. The valve 12 opens and closes the flow path of the compressed air hose 14 connected to the pipe. The compressed air hose 14 is used to evacuate the interior of the storage tank 32 using compressed air as the power source 14, and enables suction of foreign matter. A cleaning hose 52 for sucking in foreign matter is provided on one side of the storage tank 32.

  The storage tank 32 is attached to the main body 16 of the vacuum cleaner and stores (or collects) various kinds of coarse foreign matters such as chips, particles, fluid, or mud. The storage tank 32 is opened at the bottom, and the ejector 10 is attached to the top.

  The lid 24 is attached to the bottom of the storage tank 32. The storage tank 32 opens and closes at the bottom when the lid 24 is opened and closed. The air cylinders 20 and 28 are fixed on both lower sides of the storage tank 32 via brackets 22 and 30. The lid 24 is connected to the rods 20a and 28a of the air cylinders 20 and 28 at both end portions thereof. With this configuration, various foreign substances can be quickly discharged from the storage tank 32 when the lid 24 is opened and closed.

  First, compressed air is supplied to the control system 18 from an external compressor via a supply hose 50. The compressed air passes through the compressed air hose 14 and activates the ejector 10 under the control of the control system. At the same time, the valve 12 of the compressed air hose 14 is opened. The ejector 10 evacuates the storage tank 32 and introduces various foreign substances through the cleaning hose 52. Foreign matter is collected inside the storage tank 32, and the storage tank 32 is filled with foreign matter as time passes. Inside the storage tank 32, the float 34 gradually rises around the hinge 38. As a result, the rotating bar 36 provided on the float 34 operates the contact rib 42.

  Thereafter, the contact rib 42 switches the limit switch 44 “on”. In response to this switching operation, the control system 18 closes the cylinder valve, i.e. interrupts the operation of the ejector and shuts off the supply of compressed air to the compressed air hose 14.

  Thereafter, the air cylinders 20 and 28 are operated. The lid 24 is opened when the air cylinders 20 and 28 are operated. That is, the rods 20a and 28a of the air cylinders 20 and 28 move downward. Therefore, when the lid 24 connected to the rods 20a and 28a moves downward, the bottom of the storage tank 32 is opened. By doing so, the collected various foreign matters are quickly discharged from the storage tank 32.

  After the foreign matter is discharged, the lid 24 closes in about 3 seconds. The cylinder valve inside the control system 18 is opened by an air-type timer, and compressed air is supplied to the ejector 10 via the compressed air hose 14. At the same time, the ejector 10 is operated, a vacuum is formed, and a cleaning operation can be performed. By operating the automatic system, it is possible to perform suction and discharge without a separate manual operation. Therefore, it is possible to perform the cleaning work continuously alone.

  As described above, according to the present invention, all foreign matters can be quickly discharged by using the lid and the air cylinder provided at the lower portion of the storage tank, and thus labor costs due to labor loss can be reduced. As well as safe accidents. In addition, according to the present invention, various kinds of coarse substances such as chips, particles, fluid, or mud can be collected, so that there is an advantage that it can be applied to multiple purposes. In addition, according to the present invention, a caster can be attached to the bottom of the vacuum cleaner, and there is an advantage that various foreign matters can be quickly removed anytime and anywhere.
