Description

Main Manhole for Vacuum Lorry}

The present invention relates to a main manhole for a vacuum lorry, and more specifically, to a main manhole for a vacuum lorry and a vacuum lorry that heats the inside of a tank to prevent operation stoppage and malfunction due to freezing of contents contained within the tank. It's about the main manhole.

Large amounts of sewage and wastewater are produced every day in everyday life and industrial sites.

Such sewage and wastewater flows into the septic tank, is stored for a certain period of time, is decomposed by bacteria, and is discharged to the sewage treatment plant along with the sewage through the drain pipe installed in the septic tank. The excrement and wastewater that flows into the sewage treatment plant and decomposes It is discharged to the outside through a purification process.

However, in addition to the discharged sewage, sludge such as excrement remains inside the septic tank. This sludge must be treated at regular intervals, but if this is not done in a timely manner, sludge continues to accumulate, resulting in a backlog of sludge.

If this backlog continues, it is impossible for the septic tank to perform its normal function. The inability of the septic tank to perform its normal function means that sewage that has not been completely decomposed flows into the sewage treatment plant, which also makes purification of sludge impossible, and the incompletely purified sewage is discharged to the outside, polluting the natural environment. may result in

To solve this problem, the sludge generated inside the septic tank is periodically collected to prevent sludge build-up and ensure the normal functioning of the septic tank.

Sewage collection is carried out periodically using a vacuum lorry, a specially designed vehicle for sewage and wastewater treatment.

These vacuum lorry vehicles are vehicles that collect not only sludge in the septic tank but also various wastewater into a vacuum lorry tank for excrement and sewage collection using high vacuum pressure. A level window is formed inside the vacuum lorry tank to check the level of sewage, and the waste is bubbled. It consists of several parts such as piping for suction into the lorry tank, an air separator, a vacuum lorry tank, and a vacuum pump.

To briefly explain the waste collection process of a vacuum lorry vehicle, sewage such as sewage, wastewater, and excrement is sucked into the vacuum lorry tank by the operation of the vacuum pump, and the inside of the vacuum lorry tank is filled with sewage by the continuous operation of the vacuum pump. When filled, the buoy rises to the top due to the water level of the sewage, and the raised buoy pushes the float valve upward, causing the float valve to close the inlet of the pipe, blocking the inflow of sewage due to the suction of the vacuum pump. .

Then, when the vacuum lorry vehicle reaches the destination, the hose is connected to the discharge valve installed at the lower end of the vacuum lorry tank, and the discharge 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 the main manhole installation plate formed on the upper side of the vacuum lorry tank. It is obvious 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 inserted into the vacuum lorry tank.

This prior art has problems in that it cannot clean the inside of the vacuum lorry tank and cannot prevent operation stoppage or malfunction of the opening/closing module due to sticking, icing, or freezing of the contained contents.

Next, the upper body of the shaft 430 is inserted through the through hole formed in the auxiliary guide portion 220 of the intermediate case 200 and coupled to the lower body of the shaft 430. Through this, since the opening and closing disk 440 is disposed on the upper part of the auxiliary guide part 220 of the intermediate case 200, the opening and closing disk 440 can lift and lower the floating ball 420 without being caught by the auxiliary guide part 220. Accordingly, the fourth open hole 451 of the sealed guider 450 can be opened and closed by moving up and down together.

Next, the upper part of the shaft 430 is coupled to the guiding part 452 provided in the sealed guider 450 so that the sealed guider 450 is seated on the seating part 213 formed in the middle case 200. Arrange it as much as possible.

Next, the upper case 300 is coupled to the upper part of the middle case 200. At this time, since the upper case 300 compresses the sealed guider 450 at the top, the sealed guider 450 can maintain a stably coupled state even without using a separate fixing device.

Next, the heating element 600 or the washing water coupling part 700 is coupled to the input means 500 provided on one side of the intermediate case 200 according to the usage condition. Of course, depending on the usage, the heating element 600 and the washing water coupling portion 700 may be simultaneously fastened to the plurality of input means 500 provided.

When the heating element 600 is installed, the heating unit 610 is fastened to the input means 500, and the power supply unit 620 connected to the heating unit 610 is connected to a power device such as a vehicle battery or a separately provided battery. Connect to supply power to the heating unit 610. The heating unit 610 connected in this way receives power from the power device and uses it to radiate heat.

When the washing water coupling part 700 is coupled, the valve is normally blocked to prevent contents from leaking through the washing water coupling part 700. When washing the inside of the tank, a hose for supplying washing water, etc. can be connected to the washing water coupling part 700, and then the valve can be opened to spray the washing water into the tank. If the distribution pipe 720 is provided in the washing water coupling part 700, the washing water coupling part 700 is fastened to the input means 500 before coupling the intermediate case 200 to the lid 100, The washing water coupling part 700 and the distribution pipe 720 are coupled so that the distribution pipe 720 is disposed inside the middle case 200. Afterwards, the middle case 200 is coupled to the lid 100.

Figure 6 is a cross-sectional view showing the usage mode of the main manhole for a vacuum lorry according to the present invention. The main manhole 10 for the vacuum lorry combined through the above-described process determines the additional inflow of the contents by having the floating ball 420 rise and fall as shown in FIG. 6 according to the capacity with which the contents inserted into the tank are filled. This is explained in more detail as follows.

First, the connector pipe is coupled to the connection flange formed on the upper case 300 of the main manhole 10 for the vacuum lorry connected to the tank. Contents such as external sewage and wastewater flow in through these connection pipes. The contents flowing in this way pass through the passage communicating with the flange portion of the upper case 300 and the third open hole 310, and into the second open hole 210 of the middle case 200 and the first open hole of the lid 100. (110), the opening and closing module 400 sequentially passes through the ball barrel 410 and flows into the inside of 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 inside the ball container 410 are filled with 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 and lowering of the floating ball 420, and the opening and closing disk 440 provided on the shaft 430 is also raised and lowered to correspond to it. . Here, the shaft 430, which goes up and down along with the rise and fall of the floating ball 420, can be stably raised and lowered through the auxiliary guide part 220 of the intermediate case 200 and the guiding part 452 of the sealed guider 450. Through this, the opening and closing disk 440 coupled to the shaft 430 can stably and accurately open and close the fourth open hole 451 of the sealing guider 450.

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

The contents filled inside the tank through the above-described process are moved to a sewage treatment device, etc., and then the contents filled inside the tank are discharged to the outside through a discharge valve provided on one side of the tank.

In winter, when temperatures are low, the contents may freeze during filling or transporting the tank. However, the main manhole 10 for the vacuum lorry according to the present invention is equipped so that the heating element 600 coupled through the input means 500 radiates heat. In this way, the heat emitted through the heating element 600 is used to increase the internal temperature of the tank as well as the internal temperature of the main manhole for the vacuum lorry (10) to prevent the contents from freezing.

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

After 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 easily clean the inside of the tank. Of course, a plurality of input means 500 are provided, and some of the input means 500 are equipped with a heating element 600, and some of the input means 500 are coupled with a washing water coupling part 700 to form the main manhole 10 for the vacuum lorry. The heating element 600 and the washing water coupling portion 700 may be provided at the same time. In this case, there is no need to separate the heating element 600 for cleaning, and cleaning can be performed while preventing the washing water from freezing inside the main manhole 10 or tank for the vacuum lorry during cleaning.

If both the heating element 600 and the washing water coupling part 700 are not used depending on the usage, they must be removed from the input means 500, and the open portion of the input means 500 can be sealed through the stopper 800. You can.
