Abstract

PURPOSE:To reduce noise remarkably by attaching a blower to an inside surface of a manhole cover of a septic tank. CONSTITUTION:A blower 4 is attached to the inside surface of a manhole cover 3 of a septic tank 1 so as to enable to blow compressed air for aeration forced by the blower 4 into filthy water in the septic tank 1. A diaphragm blower is mot suitable. By this constitution, selection of the area for setting the blower on the ground is no longer necessary; and generation of noise is reduced remarkably.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a septic tank device configured to suck compressed air for aeration fed from 107- to sewage inside the tank.
This is designed to prevent the noise of a small horsepower blower of about W to 60 W and to make the bump mounting device advantageous.

Pressurized aeration air is sucked into a septic tank used for home use, etc. from a small horsepower blower of about 30 W to 60 W.

I! ! The building is covered with pine trees and is protected from rain and dew, but at night there were conflicts with nearby residents, and the blower motor was turned off.
1) There are a lot of things to do (, @ Preventing noise is my 8th duty.

Since the submersible blower is not installed on land, it is extremely advantageous in terms of noise prevention.
There is no installation equipment for standard septic tanks, so use 1)! il
It is l. For the second reason, the present invention requires hanging the blower on the inner surface of the purification 11n manhole cover. [It is installed by attaching it directly to the manhole and is placed in the manhole, which eliminates the need to select a location on the ground for the tower, and experiments have shown that it can significantly reduce noise. .

Figure 1 is a drawing showing an embodiment in which a diaphragm type blower (4) is mounted in a carriage-style manner on the inner surface (lower surface) of a manhole cover (3) attached to a manhole (2) of a septic tank (1). This shows a person who installed the blower (4) with the mounting leg (5) facing upward, placing the cushion rubber (6) on the leg, and attaching it with the bolt (7) passed through the top of the manhole cover (3). However, as shown in Figure 2, the manhole profit (3
It is also possible to attach the stand (8) to the inner surface of ) with bolts (7) and attach the blower mounting legs (5) to the shoes (8). The t(10) is a suction silencer, and the t(11) is a discharge hose connected to the aeration pipe.

Figure 3 shows a hanging frame (12) on the inner surface of the manhole cover (3).
) and fix it by pol) (13) and collusion (1
2) A rotary set (or Roots type) brewer (1
4) and the mounting leg (15) is fixed on the table surface via cushion rubber (not shown). In this case, to prevent mist from being sucked in, the suction pipe (
16) Manhole! (3) “
Attach the eraser (17) to the discharge side hose (18).
Connect to the aeration pipe.

The most advantageous aspect of this device is the diaphragm type blower (4) as shown in Section 1.2. In other words, the diaphragm type corresponds to the outer surface of the diaphragm.

This is because there is a suction port and a discharge port, and even if mist generated from aeration of sewage is sucked into the suction air, no mist flow is applied to the internal diamond 7-ram drive machine hη.

The blowers (4) and (14) exemplified above use ones with an output of about 30 W, but up to an output of about 60 W are effective for noise prevention.

A diaphragm type blower with an output of 30W has a pressure of 0.
17kg/am2. It is a direct connection type with a rotation speed of 1750.

The Guya 7-ram type power supply shown in Fig. 1 (output 30W1)
The installation type with a pressure of 0.17/as" and the rotation speed of 1750) and the installation type on the Vi of the same type Guya 7 lamp power in the United States, both were installed at a distance of 1.5 - or the above odor. The background noise is the external noise measured after the blower is stopped, and in the case of the present invention, the noise when the blower is running is the same as the noise, and it is extremely effective for noise prevention. I was able to prove it.

In the present invention, the manhole M (
3) can effectively block noise leakage.

The present invention can also significantly improve the effect of external temperature on the blower, especially in the summer. 1111 In the case of a land-based installation in the United States, when the temperature is 35°C, the temperature of the blower that receives direct sunlight will exceed 80°C, and the motor and bearing
However, in the case of Fig. 1 of the present invention, even if the manhole (3) is exposed to direct sunlight, there is no flow of sewage inside the manhole (2). Because the surrounding area was underground, Bu97- itself did not rise above 65°C. Note that the above measurements were performed by pasting thermolabels, so there is a large error! !
The noise prevention effects and summer temperature effects shown in the table above are obtained by all embodiments of the present invention.

As clarified from the above description, the present invention provides a blower (4), ( 14) Attach the manhole (2)
A purifying M structure that makes you feel inside! It is a device that can prevent noise from small, low-horsepower blowers and makes it easy to find a place to install it.
