It is about the main manhole for the dragon.

A large amount of sewage and wastewater is produced every day in everyday life and industrial sites.

Such sewage and wastewater are introduced into the septic tank and stored for a certain period of time, decomposed by bacteria and discharged to the sewage treatment plant together with the sewage water in the septic tank through the drain pipe installed in the septic tank. It is discharged to the outside through the purification process.

However, in addition to the discharged sewage, sludge such as excreta remains inside the septic tank. Such sludge should be treated at regular intervals, but if this is not done in a timely manner, the sludge will accumulate continuously, resulting in sludge accumulation.

If this congestion phenomenon continues, it is impossible to perform the normal function of the septic tank. The impossibility of performing the normal function of the septic tank means that undecomposed manure flows into the sewage treatment plant, which makes it impossible to purify the sludge in the sewage treatment plant as well, and the incompletely purified sewage is discharged to the outside, causing pollution of the natural environment. may cause

To solve this problem, by periodically collecting the sludge generated inside the septic tank, the sludge accumulation phenomenon is prevented in advance so that the normal function of the septic tank is performed.

Sewage collection is also carried out periodically by means of specially designed vehicles for wastewater and wastewater treatment, namely, the Vacuum Lorry.

This vacuum lorry vehicle collects not only the sludge in the septic tank but also various wastewater into a vacuum lorry tank for manure and filth collection using high vacuum pressure. It is composed of several parts such as a pipe for suction into the lorry tank, an air separator, a vacuum lorry tank, and a vacuum pump.

Briefly explaining the waste collection process of the vacuum pump, the vacuum pump is driven into the vacuum pump, and the waste water or manure is sucked into the vacuum pump. When it is filled, the buoy rises to the top by the level of filth, and the raised buoy pushes the float valve upward, and the float valve closes the inlet of the pipe to block the inflow of filth by suction of the vacuum pump. .

Then, when the vacuum lorry vehicle reaches its destination, the hose is connected to the discharge valve installed at the lower end of the vacuum lorry tank, and the drain valve is opened to discharge the waste stored in the vacuum lorry tank.

Such a valve device for a waste collection vehicle is generally referred to as a main manhole for a vacuum lorry, and this main manhole for a vacuum lorry is firmly mounted on a main manhole installation plate formed on the upper side of the vacuum lorry tank. It is self-evident that the main manhole installation plate of the vacuum lorry tank is open so that the main manhole for the vacuum lorry can be installed while being inserted into the vacuum lorry tank.

The prior art has a problem in that it is not possible to clean the inside of the vacuum lorry tank, and it is not possible to prevent the operation stop and malfunction of the opening/closing module due to sticking, freezing, or freezing of the contents being accommodated.

6 is a cross-sectional view showing the mode of use of the main manhole for vacuum lorry according to the present invention. In the main manhole 10 for vacuum lorry combined through the above-described process, the floating ball 420 ascends and descends as shown in FIG. 6 according to the capacity to be filled with the contents inserted into the tank, and determines the additional inflow of the contents. This will be described in more detail as follows.

First, the connecting pipe is coupled to the connecting flange formed in the upper case 300 of the main manhole 10 for the vacuum lorry connected to the tank. Contents such as external sewage and wastewater are introduced through this connection pipe. The contents introduced in this way are the second opening hole 210 of the middle case 200 and the first opening hole of the lid 100 through a passage communicating with the flange portion of the upper case 300 and the third opening hole 310 . (110), the opening/closing module 400 sequentially passes through the ball barrel 410 and is introduced into the tank.

When the contents are continuously filled in this way, the inside of the tank is filled, and when the contents corresponding to the capacity of the tank are filled, the floating balls 420 provided in the ball barrel 410 are filled by the contents as shown in FIG. 6 . , become wealthy.

At this time, the shaft 430 coupled to the upper part of the floating ball 420 is raised and lowered together with the lifting of the floating ball 420 , and the opening/closing disk 440 provided on the shaft 430 is also raised to correspond thereto. . Here, the shaft 430, which ascends and descends together with the lifting of the floating ball 420, can be stably raised and lowered through the auxiliary guide 220 of the intermediate case 200 and the guiding portion 452 of the closed guider 450. Through this, the opening/closing disk 440 coupled to be connected to the shaft 430 can open and close the fourth opening hole 451 of the sealing guider 450 stably and accurately.

As described above, when the contents are continuously filled into the tank and the floating ball 420 rises to the maximum, that is, when the contents of the capacity corresponding to the storage capacity of the tank are filled, the opening/closing disk 440 is closed guider 450 ) to close the fourth open hole 451 to prevent further inflow of contents.

After the contents filled into the tank through the above-described process are moved to a sewage treatment device, the contents filled in the tank are discharged to the outside through a discharge valve provided on one side of the tank.

In winter when the temperature is low, the tank may be filled with contents or the contents may be frozen during transport. However, the main manhole 10 for vacuum lorry according to the present invention is provided so that the heating element 600 coupled through the input means 500 dissipates heat. As such, by using the heat emitted through the heating element 600 to increase the internal temperature of the tank as well as the internal temperature of the main manhole 10 for the vacuum lorry, the contents are prevented from freezing.

Through this, freezing of the contents being filled or the contents contained in the tank is prevented, and the process of injecting and discharging contents is performed smoothly.

After the transport of the contents is completed, the heating element 600 coupled to the input means 500 is removed, and the washing water coupling part 700 is coupled to the input means 500 to facilitate cleaning of the inside of the tank. Of course, a plurality of input means 500 are provided, some input means 500 are provided with a heating element 600 , and some input means 500 are coupled with a washing water coupling part 700 to the main manhole 10 for vacuum lorry. The heating element 600 and the washing water coupling part 700 may be provided at the same time. In this case, it is not necessary to separate the heating element 600 for washing, and washing can be performed while preventing the washing water from freezing in the main manhole 10 for the vacuum lorry or the inside of the tank during washing.
