  An object of the present invention is to provide a water treatment device that is operated by electric power from a generator using a gas cylinder as a gas source.

  In the water treatment apparatus of the present invention, a pump that takes in raw water, a filtration device through which water from the pump flows, and a generator that generates electric power for driving the pump are installed on a common base. In such a water treatment apparatus, the power generator is provided with a gas cylinder powered by a gas engine and supplying gas to the gas engine.

  According to one aspect of the present invention, an inverter controller for controlling the pump is provided.

  In one aspect of the present invention, the water discharged from the pump is supplied to the filtration device via a pressure tank (accumulator).

  In one aspect of the present invention, the gas cylinder is an LP gas container, and the LP gas container is disposed behind a partition provided on the base.

  In one embodiment of the present invention, the gas cylinder is a fuel container for a cassette stove (cassette cylinder), and the cassette cylinder is mounted on a cassette cylinder mounting portion provided in a cover case surrounding the generator.

  In one embodiment of the present invention, a mechanism for injecting a disinfectant is provided, and the disinfectant is mixed with the filtered water.

  In one embodiment of the present invention, a container that contains a solid disinfectant and through which the filtered water flows is provided.

  In one embodiment of the present invention, at least a part of the water contact member is transparent.

  The water treatment apparatus of the present invention can obtain purified water by operating a generator using gas in a gas cylinder even during a power outage.

It is a side view of a water treatment device concerning an embodiment.

  Hereinafter, an embodiment will be described with reference to FIG.

  Wheels 3 such as casters are provided on a base 2 of a box-shaped housing 1, and the housing 1 is movable. A partition wall 4 having legal strength is provided in the housing 1, and an LP gas container 6 is installed in a cylinder installation space 5 behind the partition wall 4 (right side in the figure).

  The front side (the left side in the figure) of the partition 4 is a device installation space 7.

  The equipment installation space 7 includes a three-way valve 10 to which a water intake 9 is connected, a pump unit 12 into which water is introduced from a first outlet of the three-way valve 10 via a pipe 11, and a pump unit 12. A filtration filter 16 into which water is introduced through a pipe 13, a check valve 14, and a pipe 15; an activated carbon filter 18 into which filtered water filtered by the filtration filter 16 is introduced through a pipe 17; A disinfectant mixing section 20 into which water passing through 18 is introduced via a pipe 19, and a supply pipe 21 for supplying water passing through the disinfectant mixing section 20 to the outside of the housing 1 are provided.

  The second outlet of the three-way valve 10 is connected to the pipe 15 via the pipe 22, the hand pump 23 and the pipe 24.

  The pump unit 12 includes a motor, a pump driven by the motor, and the like.

  In the equipment installation space 7, a generator unit 27 to which gas is supplied from the LP gas container 6 via a hose 26 is further installed. The generator unit 27 includes a gas engine and a generator that is driven to rotate by the gas engine. The motor of the pump unit 12 operates by the power generated by the generator.

  An operation panel 28 and a controller (not shown) for controlling the operation of the gas engine and the motor are provided at an upper portion of the housing 1. Preferably, the pump unit is controlled by inverter control. By controlling the pump unit with an inverter, the starting current can be suppressed, the generator can be downsized, and the discharge flow rate and pressure can be stabilized.

  A screen 29 composed of a liquid crystal panel or the like for displaying the operation status of each device is provided on the upper part of the housing 1. The screen 29 may be a multilingual display method.

  At the top of the housing 1, an indicator light 30 and an illumination 31 such as an LED are installed. The lamp of each color of the indicator lamp 30 may be turned on during operation to indicate the driving situation.

  As the filtration unit 16, a unit provided with a filter, a membrane, an adsorbent, and the like can be used, but is not limited thereto.

  A liquid disinfectant is injected into the disinfectant mixing section 20 using a pump or an ejector. As the disinfectant, since clean water may come into contact with the human body as a shower or the like, a disinfectant that can be used as a food additive is preferable.

A method using a solid agent as a disinfectant is also effective. Solid disinfectants have the advantage of less degradation upon storage.
In addition, in the case of the use which does not assume contact with a person, injection of a disinfectant can be omitted.

  It is preferable that the top surface and the peripheral side surface of the housing 1 be surrounded by a panel (not shown) to reinforce the housing 1 and protect each device. In addition, it is preferable that at least a part of the water contact members such as the filter, the cartridge, and the piping be transparent so that the flow of water can be visually observed.

  As the above-mentioned pump unit, one having a built-in inverter and a pressure tank (accumulator) is preferable. If a pressure tank is installed on the discharge side of the pump, the flow rate can be stably maintained even if the resistance on the discharge side changes.

  The provision of the partition wall 4 eliminates the necessity of taking a legally required 2 m separation, thereby reducing the installation space.

  The pipe 9 may be a pipe or a hose. It is preferable to install a coarse screen on the tip side (suction port) of the pipe 9 to take measures against stones, dust, and dead leaves.

  In the water treatment apparatus configured as described above, in the event of a disaster or the like, gas is supplied from the LP gas container 6 to the generator unit 27 to generate power, the pump unit 12 is operated, and the pool water, the water storage tank, the well water , Ponds, rivers, etc., can be purified by the filter 16 and the activated carbon filter 18, the disinfectant can be mixed in the disinfectant mixing section 20, and purified water can be supplied from the pipe 21. A gas water heater (not shown) for heating the purified water may be installed.

  In FIG. 1, the gas is supplied from the LP gas container 6 to the generator unit 27, but a generator unit having a cassette cylinder mounting portion may be used. In this case, the partition 4, the space 5, the LP gas container 6, and the hose 26 can be omitted.

  As such a cassette cylinder type generator unit, a commercially available product can be used. The gas cylinder mounting portion is provided in a cover case surrounding the generator and the pump, and is configured so that a cassette cylinder can be detached from the outside.
