Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a human waste treatment device, and more particularly to a human waste treatment device provided with a human waste pretreatment device.

(Prior Art) In the conventional human waste processing apparatus, as shown in FIG. 4, the human waste collected by the collecting truck 24 is directly put into the input tank 25, and the foreign matter in the human waste is crushed by a crushing pump 26 or the like. , which is sent to the next processing step and subjected to purification treatment.

(Problem to be solved by the invention) Since the human waste is directly put into the input tank 25, there are cloths, plastic sheets, etc. mixed in the human waste on the upper part of the input tank 25.
Rubber, wood chips, and other foreign substances; lumps and scum formed by fermentation of these foreign substances and human waste; and sand, stones, metal objects, and relatively heavy foreign substances mixed in the human waste separated at the bottom of the input tank 25. It is becoming.

Therefore, in conventional human waste processing equipment, human waste is introduced from the lower part of the input tank 25 and the human waste is introduced into the crushing pump 2.
6, the foreign matter in the human urine is chopped up and removed in a later process.

When feeding the human waste from the input tank 25 to the next process, cloth, plastic, rubber, etc.
A crushing pump 26 having a function of crushing wood chips, etc. is used, but since the crushing pump 26 only crushes wood chips, etc., scum, solid sediments, etc. are formed in the input tank 25, and this causes the crushing. There were problems in that the pump 26 and the like caused mechanical troubles, and that management such as removing scum, solid sediment, etc. in the charging tank 25 required a lot of labor and cost.

The present invention was made in order to solve the above-mentioned conventional problems. ,
By installing an impeller in this primary chamber,
It is an object of the present invention to provide a human waste processing device equipped with a ``human waste pretreatment device'' that removes large foreign objects without chopping them up using a crushing pump as in the conventional method.

(Means for Solving the Problems) In order to achieve the above object, the human waste treatment device of the present invention is connected to a collecting truck via a hose, and separates human waste through a screen plate from human waste that passes through a screen plate and foreign matter that does not pass through. a primary chamber separated into two, a secondary chamber for receiving human waste passing through the screen plate, an impeller provided in the primary chamber adjacent to the screen plate and rotated by a rotating means, and discharging residual foreign matter from the primary chamber. A human waste pretreatment device is provided with a discharge means for discharging human waste.

(Function) In the human waste treatment device configured as described above, when the collecting car and the primary chamber are connected via a hose and the impeller is rotated by a rotating means, the impeller agitates and disintegrates the human waste and the screen plate is opened. Since the blockage is removed, the human waste that can pass through the screen plate is sent to the human waste processing device through the secondary chamber of the human waste pretreatment device.

On the other hand, large foreign objects such as cloth, plastic sheets, rubber, pieces of wood, etc. remain in the primary chamber, and the remaining foreign objects are discharged by the discharge means.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, A is a human waste collection vehicle, and the human waste collection vehicle A has a tank 2 mounted on a vehicle 1.
When the pressure inside the tank 2 is reduced by a vacuum pump (not shown), the human waste is collected by the hose 3, and when the pressure is increased, the hose 3 is used to collect the human waste from the tank 2.
It is designed to allow the human waste inside to be drained out.

B is a human waste pre-processing device, human waste pre-processing device B
schematically includes a primary chamber 4, a secondary chamber 7, and an impeller 1.
0, a discharge means 16, etc.

Reference numeral 4 denotes a sealed primary chamber in the human waste pretreatment apparatus B, and as shown in FIGS.
The hose 3 of the human waste collecting truck A is connected to the machine to send the collected human waste.

In the lower part of the other side of the primary chamber 4, there is a secondary chamber 7 which is separated from the primary chamber 4 by a screen plate 6 having a hole of 3 to 5 mm or a similar slit to separate human waste and foreign matter. Adjacent to the lower part of this secondary chamber 7 is connected a delivery pipe 8 for delivering the human waste sent through the screen plate 6 to an input tank 21 (to be described later), and this delivery pipe 8 is equipped with an on-off valve 9.

Reference numeral 10 denotes an impeller installed near the screen plate 6 of the primary chamber 4, as shown in FIG. This rotating shaft 11
The other end is connected to an external reducer motor 12 and a shaft joint 13.
When the reducer motor 12 is in operation, the impeller 10 is rotated at a high speed with a tip circumferential speed of 30 m/sec, and the human waste is stirred and disintegrated, and the impeller 10 is attached to the screen plate 6 side as shown in FIG. As shown, a blade member 14 for causing cavitation is attached, and the cavitation caused by this blade member 14 prevents clogging of the screen plate 6.

Reference numeral 15 denotes a water pipe connected to the upper part of the primary chamber 4 as shown in FIG. 2, which supplies water for cleaning into the primary chamber 4.

16 is a screen plate 6 of the primary chamber 4;
A means for discharging foreign matter (e.g., a discharge pipe 16) is provided on the opposite side as shown in FIG. An on-off valve 17 is provided to discharge foreign matter remaining in the primary chamber 4.

Reference numeral 18 denotes a foreign matter reservoir, which is placed at a position where foreign matter falls from the discharge pipe 16 as shown in FIG. The foreign matter is separated and returned to the primary chamber 4 by the return pump 20, and the accumulated foreign matter is incinerated in an incinerator (not shown).

Reference numeral 21 denotes a feeding tank for human waste from which foreign substances have been separated, and as shown in FIG. , which is fed to the next device that processes human waste.

In addition, in the conventional human waste pretreatment device (Fig. 4), the foreign substances in the human waste are crushed by the crushing pump 26, so that foreign substances that cannot be removed in the subsequent process, especially non-organic substances such as plastics and rubber, are contained. However, in the human waste treatment equipment of this embodiment, when making human waste into fertilizer, the human waste pre-processing device B is used to screen the human waste. Since it is possible to separate the human waste that passes through the plate 6 from the foreign matter that does not pass through, it is possible to eliminate the inhibiting factors that have conventionally occurred.

(Effects of the invention) Since the present invention is configured as described above, it produces the effects described below.

This is a human waste pre-treatment device that can separate human waste that passes through the screen plate from foreign matter that does not pass through, so the screen plate can remove many of the causes of sediment that conventionally occur. The labor and cost for removing scum, precipitates, etc. that have arisen can be reduced.

In addition, the human waste pre-processing device allows large foreign objects to be removed without breaking up the foreign objects using a crushing pump as in the conventional method, and also prevents breakdowns in the pumps used in the human waste processing device to transfer human waste. It has unique effects such as being able to.
