JPH06424Y2 - Liquid fertilizer for human waste - Google Patents

Description

[Detailed Description of the Invention] (Industrial field of application) This device is installed in a domestic urine tank, and a sewage in the human urine tank is charged with a decomposition auxiliary agent containing bacteria as a main component to convert the sewage into liquid fertilizer. The present invention relates to a device which is used to deodorize human waste at the same time.

(Prior Art) There are many types of purifiers that decompose sewage in a human urine tank to release water and gas and discharge it out of the urine tank. In addition, various devices for composting human waste have been developed.

(Problems to be solved by the invention) However, the former wastes wastewater decomposed into bacteria even though it can be used as an excellent liquid fertilizer.

In addition, the latter is a heating device for a human waste tank, a stirring device, and a first
Equipment such as secondary and secondary fermentation tanks, peat moss as a main component mixed with aerobic bacteria, periodical introduction of compost base, etc., and a large amount of equipment costs, maintenance costs and labor are required, so at home There are drawbacks that cannot be easily implemented. Moreover,
Sludge is solidified and can be used as compost, but sewage is purified and then discharged, but like the former, insufficient management also contributes to river pollution.

(Means for Solving Problems) Therefore, the present invention is intended to be attached to a domestic night soil tank to decompose sewage to be used as fertilizer and to deodorize the night soil tank. The structure is as follows.

That is, an exhaust pipe equipped with an exhaust fan is connected to a main cylinder whose lower end is opened into the waste water of the urine tank and whose upper part is projected from the lid.

The inspection lid, which is detachably attached to the upper end of the main cylinder, is equipped with a decomposition auxiliary agent injection cylinder that opens into the main cylinder and decomposes sewage.

Further, along the main cylinder, a rising portion that projects from the inside of the human urine tank to the outside of the lid, and an upward ejection port and a downward ejection port that are bent from the lower end of the rising portion and are located below the opening of the lower end of the main cylinder. A blower pipe having a jetting part composed of and is connected to the blower, and the rising part is rotatably attached so that the jetting part can be moved to the outside below the opening.

(Function) A decomposition auxiliary agent containing bacteria that decomposes sewage as a main component is charged from the charging cylinder into the waste urine tank, and air is blown from the blower to the jetting portion through the blower pipe. The air ejected from the downward ejection port of the ejection unit stirs the sewage and decomposes the sewage into water and gas such as carbon dioxide. Further, the air jetted upward from the upward jet port cooperates with the exhaust fan of the exhaust pipe, and sends moisture and gas that have become bubbles from the opening to the main cylinder upward.

The bubbles sent from the main tube into the exhaust tube are separated into drain and gas, the drain drops from the exhaust tube through the main tube into the urine tank, and the gas is exhausted odorlessly by the exhaust fan.

The sewage that has become liquid fertilizer is moved to the outside of the opening below the main cylinder by rotating the rising part of the blower pipe, and then the removable inspection lid is removed to remove the submersible pump from the main cylinder. Take it down into the dirty water and take it out.

(Effect) Since the discharged sewage can be used as liquid fertilizer without being used so far, it can be effectively used for plant cultivation without causing river pollution.

In addition, power consumption is only one exhaust fan and one blower, so electricity costs are low, equipment costs are extremely low, maintenance is easy, and it is easy to implement for general households and farmers. it can.

(Example) Hereinafter, an example will be described with reference to the drawings.

Reference numeral 1 is a well-known domestic human waste tank, and 2 is a lid that can be opened and closed.

A main cylinder 3 has an inner diameter large enough to allow a small submersible pump to be taken in and out, and in the embodiment, an inner diameter of approximately 200 mm. The main cylinder 3 has an opening 5 at the lower end 4 that opens into the waste water W of the urine tank 1, and an upper portion 6 projects from the lid 2. An inspection lid 7 is detachably attached to the upper end of the main cylinder 3.

Reference numeral 8 denotes a disintegration auxiliary agent charging cylinder, which is attached to the inspection lid 7 and hangs down to open in the main cylinder 3. A vent 9 is provided in a lid 9 which is detachably attached to the insertion tube 8.

Reference numeral 10 denotes an exhaust stack, which is appropriately connected and formed by an elbow for the purpose of repair and inspection, and the base is connected to the upper part 6 of the main cylinder 3,
An exhaust fan 11 is attached to the upper end.

Reference numeral 13 denotes a blower pipe connected to the blower 12, and includes a rising portion 14 along the main tube 3 which projects from the inside of the human waste tank 1 to the outside of the lid 2, and an upward ejection port 15 and a downward ejection port 16. And a squirting part 17. This spout 17 is a rising part
The lower end of 14 is formed by connecting a chee to the horizontally bent end, and is located below the opening 5 of the main cylinder 3. Therefore, the upward ejection port 15 ejects air upward to form the sewage W into bubbles in the main cylinder 3, and the downward ejection port 16 ejects air downward to stir the sewage W.
Reference numeral 18 is a sound deadening pipe attached to the upward ejection port 15.

Further, the rising portion 14 is loosely fitted to the support fitting 19 and the lid 2 fixed to the lower end portion 4 of the main cylinder 3, and the upper end portion is connected to the elbow 20 without being glued.

Therefore, as shown in FIG. 2, the wastewater W in the human waste tank 1
To take out the liquid fertilizer as liquid fertilizer, the rising portion 14 is rotated to move the ejection portion 17 to the outside of the opening portion 5, and the submersible pump P is inserted into the main cylinder 3 from which the lid 2 is removed.
Liquid fertilizer is taken out about once a month.

In addition, as the decomposition aid for sewage, a commercially available product containing bacteria as a main component is used.
