Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention is intended for fiber handling factories that require treated fibers to be kept at a predetermined humidity, such as textile factories, yarn twisting factories, and others. be.

``Conventional technology'' Conventionally, a humidifier was installed in a factory, and a fan installed in the humidifier sucked the air inside the factory, which contained fluff, etc., into the container. , Humidify the air by passing it through a fountain in the container, separate and remove excess moisture, and release this air into the factory by the fan to maintain an appropriate humidity in the air in the factory. The separated and removed water is led to a wastewater tank, and then introduced into a freshwater tank through a filtering material, such as a filter net or a filter cloth, and the water in the freshwater tank is passed through a pump, for example, to the water supply tank. It was used to humidify the air inside the vessel, and when the water level in the tank fell below a predetermined water level, fresh water was replenished into the tank by the action of, for example, a float valve.

Then, the filter material becomes clogged due to fly fluff mixed in the waste water. Since the timing is generally known from experience, when that time comes, the timer is automatically activated or the sewage tank's on-off valve is opened manually, and the fresh water supply nozzle installed in the fresh water tank is turned on. For example, by opening the tap water tap and supplying tap water, the tap water from the nozzle is sprayed onto the filter material to flush out fluff, etc. that can clog the filter material, into the sewage tank. wash,
In addition, water for air humidification that is sent from the fresh water tank to the humidifier is stopped, thereby eliminating unnecessary wastewater flowing from the humidifier into the sewage tank.

By the way, the purpose of sucking the air inside the factory into a humidifier and releasing it into the factory is to keep the temperature inside the factory as constant as possible and prevent it from changing suddenly. This is because this is an essential condition for this type of factory.

"Problems to be Solved by the Present Invention" In the above case, the filter medium becomes clogged too quickly, and therefore it is necessary to frequently activate the activation timer or perform manual operation. Not only is this necessary, but it is also an unbearable hassle, and it is extremely inefficient because the operation of the humidifier has to be stopped each time, and the present invention aims to solve this problem.

"Means for Solving the Above Problems" In the present invention, the waste water led from the humidifier to the sewage tank is used, and the waste water is forced to flow out toward the filter material surface on the sewage tank side. A device was installed.

``Function'' By doing this, the waste water from the humidifier always cleans the filter material surface on the sewage tank side while flowing into the sewage tank, and this inflowing waste water itself is also protected from wind. Although cotton is mixed in, this fluff will also remain floating in the sewage tank.

``Example'' Air in a factory is sucked into a humidifier 2 through an intake port 1, and is discharged into the factory through a slit 4 using a fan 3, and this sucked air is guided from a fresh water tank 5. Humidification is performed with water spouting from the small mouth 7 of the clean water pipe 6, and excess water is separated by a separating blade 8 and allowed to fall.
0, and from this sewage tank through the filtration net 11 to the fresh water tank 5, and when the water level in the fresh water tank is about to drop below a predetermined level (the air discharged into the factory is filled with stagnant moisture) Float valve 12 operates to replenish fresh water into the tank. The present invention is based on the above, and the lower end is at the upper end of the sewage tank side surface of the filtration net 11 provided in the vertical direction, and the upper end is above the sewage tank 10. A slanted guide plate 13 is provided so that the waste water from the humidifier collides with this guide plate and flows down the filtering net surface in the sewage tank. For this reason, fly fluff, etc. are prevented from adhering to the filter net surface, and the fly fluff, etc., floats in the sewage tank. However, the filtration capacity of the filtration net will eventually disappear, or the filtration capacity will be lost.
When the water level significantly decreases, you should set a timer or manually open the sewage tank and shut off the flow of water from the fresh water tank to the humidifier.
In addition, at this time, a water pipe 18 is introduced into the fresh water tank, and a nozzle 19 is installed in this pipe, and when the humidifier stops, tap water is jetted from this nozzle toward the filter network for cleaning. It is effective. The opening and closing of the tap 21 of this water pipe is done by the timer or manually. Note that tap water is always sprayed in the air.

"Effects of the Invention" In the present invention, the surface of the filter net is constantly washed by the water flowing from the upper end, and fluff and the like do not easily adhere to the surface of the filter net. Therefore, the time it takes for the filtration net to become clogged is extremely long compared to conventional ones, which naturally makes it possible to operate the humidifier continuously for a long time, which improves the operating efficiency of the factory. will improve significantly. Furthermore, in the present invention, since the wastewater itself that is naturally sent from the humidifier to the sewage tank is effectively used, the amount of water used does not become particularly large, and it is extremely effective from an economic point of view. .

In addition, 14 and 15 in the figure are long and short electrode rods,
When the water level in the sewage tank rises and reaches the short pole rod 15, an electric circuit is closed between the two electrode rods, a timer (not shown) is activated, the solenoid 16 is energized, and the on-off valve 17 of the sewage tank 10 is opened. , the sewage from the sewage tank is discharged, and the fresh water tank 5 and the pipe 6 in the humidifier 2 are
and are now being cut off. In addition, in some cases, the water pipe 1 that has entered the fresh water tank 5
A pot 21 such as No. 8 is opened, and a nozzle 19 at the tip of this pipe is used to spray water onto the back side of the filter net to wash the filter net. Note that the operation of the knob 21 can also be performed manually if necessary.

Note that the filter net 11 is provided above the water level of the fresh water tank. The reference numeral 20 is an overflow pipe just in case. In addition, 22 is a pot installed on the pipe connecting the humidifier and the fresh water tank.
23 indicates a pump installed on the same pipe.
