Description

Sewage leakage prevention device of the compressed trucks {A DEVICE OF PREVENT OUTFLOW FOR WASTE WATER}

The present invention relates to a compressed chariot, and more particularly, the amount of sewage generated and stored from food waste contained in garbage in the process of being compressed in a loading box for transporting household waste generated at home or a restaurant. The present invention relates to a sewage spill prevention device for improving the problem of sewage spillage caused by exceeding the capacity of the existing sewage tank.

In general, compressed chariots serve to collect and compress food waste or dirt discarded at a place such as a general home or a restaurant, and transport them to a fixed place. And, the cylinder for moving forward and backward of the shield plate, and the operating lever for operating and controlling the cylinder is configured, when the load exceeds the set pressure (loading pressure) when the cylinder is automatically contracted, the loading is made and discharged Move the lever to advance the shield to push the garbage out and place it.

On the other hand, the food culture of Korea is composed of soup-based diets such as stew, vegetables, and fruits, so that a large amount of sewage is generated from food waste, and there is not much problem in collecting and transporting such food waste.

Therefore, in recent years, by installing a sewage collection tank having a predetermined capacity in the bottom of the loading bin, it is possible to store (process) the sewage discharged during the compression process of the waste containing a lot of water as described above.

However, in the summer months, many household wastes containing fruit peels and other water are thrown away at homes, and garbage from agricultural and fish market is a waste that contains a lot of water or is used in water. Because the water contains a lot of water, more than 550 liters of water is generated during one-time collection of 5 tons vehicle.

The sewage tanks of all compressed and developed vehicles in Korea have a storage capacity of only 300ℓ. If the storage capacity of the sewage exceeds this, the sewage is sprinkled on the roadside from the trash box during transportation, causing odor and The roadside was a problem such as damage to the pedestrians.

In addition, in order to solve the above problem, in order to increase the internal capacity of the sewage tank, a new large-capacity tank must be installed, which requires excessive replacement cost of the tank, and even if the tank is replaced, the lower space of the loading box is no longer used. There was a difficulty in increasing the dose.

The present invention has been proposed to solve the above problems in the prior art, while maximizing the storage capacity of the sewage while using the sewage tank of the compressed propulsion vehicle that is conventionally spread as is generated during the collection, compression process of household waste Even if the amount of sewage exceeds the capacity of the existing sewage tank, the purpose is to prevent leakage to the outside.

The object of the present invention is to provide a compressed vehicle in which a sewage collection tank having a predetermined capacity is provided at the bottom of the bottom surface of a loading box of a cleaning vehicle:

At the bottom of the loading box, an auxiliary tank connected to the sewage collection tank and the sewage guide pipe is mounted, and a sensor for detecting the level of sewage is provided in the auxiliary tank;

The upper storage tank is equipped with an upper storage tank connected through the auxiliary tank and the sewage transfer pipe;

The auxiliary tank is provided with a submersible pump for forcibly conveying to the upper storage tank when the sewage flowing into the auxiliary tank exceeds a predetermined amount.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, looking at the overall configuration of the sewage outflow prevention device according to the embodiment through FIG. 1 as follows.

As shown, a sewage collection tank 1 of 300 l capacity, which has been previously installed, is located at the bottom of the loading box 10 of the true car, and an auxiliary capacity of 72 l connected to the sewage guide pipe 7 at a position adjacent thereto. The tank 2 is newly installed, and the upper storage tank 6 having a capacity of 270 L connected to the auxiliary tank 2 and the sewage pipe 8 is installed at the upper portion of the loading box 10.

In particular, as shown in an enlarged view in FIG. 2, in the auxiliary tank 2, a foreign matter removing device 5 made of a fine mesh is formed on the inflow side of the sewage from the sewage guide pipe 7. Water level sensor (3) is attached to detect the level of sewage to be stored, and the submersible pump (4) for forcibly conveying to the upper storage tank (6) when the amount of sewage flowed in with a certain amount Each is equipped to be operated by a 24V DC motor.

And, as shown in a perspective view by cutting a part to help the understanding of the internal structure of the upper storage tank 6 in Figure 3, the sewage transfer pipe 8 is connected to one side to the upper storage tank (6) The sewage discharge pipe 9 is configured at the lower end of the opposite side, and the gas discharge port 13 for discharging the gas generated from the sewage to the outside can be confirmed.

In particular, the interior of the upper storage tank (6) partitioned a large number of internal spaces by forming a diaphragm (12) at regular intervals to prevent the sewage of stored sewage transported to the inside as shown in part cut in Figure 3, Each space is communicated through the lower portion of the diaphragm 12 located at a predetermined height so that the sewage can move freely.

In the drawings, reference numerals 11 and 14 denote sewage discharge valves, and 15 denote vehicle batteries.

In this way, the sewage storage process and the effects of the seismic leakage preventing device is constructed in the compressed vehicle development will be described below.

First, the sewage generated during the compression process for transporting the collected household waste is first flowed into the sewage collection tank 1 and is stored. If the sewage generated in this way exceeds a predetermined amount, the sewage guide pipe (7 ) Flows into the auxiliary tank (2) located at the lower end.

And the sewage to be transported to the auxiliary tank (2) is passed through the foreign matter removal device (5) to filter foreign matters, such as suspended solids contained in the sewage of household waste, such inflow of the auxiliary tank (2) gradually increases When the water level in the tank reaches a predetermined height, the water level sensor 3 detects this and sends an operation signal ON to the submersible pump 4.

When the submersible pump 4 is operated by the operation signal, the sewage stored in the auxiliary tank 2 is forcibly moved to the upper storage tank 6 through the sewage transfer pipe 8. As the operation of (4) takes place for a certain period of time, when the amount of sewage in the auxiliary tank (2) falls below the set range of the level sensor (3), the sensor sends a stop signal (OFF) to the submersible pump (4) again. Will stop the operation. As the pump is repeatedly started and stopped by applying the signal from the water level sensor 4, the auxiliary tank 2 can maintain the water level within a certain range while preventing the overflow of sewage.

On the other hand, the sewage that is moved to the upper storage tank (6) through the sewage transfer pipe (8) is filled from the sewage discharge pipe (9) connected downward from the lower side of the tank in the inner space of the upper storage tank (6) The filthy water stored in the tank may be prevented from being shaken by a plurality of diaphragms 12 formed in the tank at a predetermined interval even if the vehicle shakes. In addition, as stored for a long time in the upper storage tank (6) toxic gas that can be generated from the sewage is discharged to the outside through the gas outlet (13).

In addition, since the sewage is stored in the upper storage tank (6), the sewage transfer pipe (8) connected to one side of the sewage discharge pipe (9) connected to the lower end of the opposite side is connected to the upper end of the tank Therefore, it can be seen that the backflow of the sewage does not occur until the sewage is completely filled in the inner space of the upper storage tank 6.

And when the collection and transportation of household waste is completed, the operator to discharge the stored sewage to the sewage treatment tank, the operator discharge valves (11, 14) installed at the lower end of each of the auxiliary tank (2) and sewage discharge pipe (9) Will open.

As a result, as the discharge valves 11 and 14 are opened, the sewage stored in the upper storage tank 6, the auxiliary tank 2, and the sewage collection tank 1 is discharged to an external sewage treatment tank. As a result, the final treatment of sewage generated during the collection of household waste is completed.

Therefore, the sewage spill prevention apparatus of the present invention uses a low-capacity sewage collection tank that has been used in the past, but a separate storage to improve the problem of increasing the capacity of the tank further due to the narrow space of the lower compartment of the truck. By installing an additional tank on top of the loading box, it maximizes the storage capacity of sewage at low installation cost.

That is, the sewage storage capacity of the Jinjak according to the embodiment is 300 liters of the sewage collection tank (1) + 72 liters of the auxiliary tank (2) + 270 liters of the upper storage tank (6) to be able to store up to approximately 642 liters at the maximum. As a result, it can be seen that the generation of sewage can cover 550 L, which occurs especially at many times.

In addition, the bottom space of the storage box in which the auxiliary tank (2) serving to move the sewage to the upper part by using the submersible pump and the collection tank (1) where the sewage is initially collected is located close to the road floor. Since it is impossible to increase the capacity any more because it must be maintained above a certain height, it is preferable that the upper storage tank 6 can be increased in capacity by any amount, so that the upper storage tank 6 is manufactured and installed with the necessary capacity for the purpose of the vehicle to be used. can do.

In addition, as there is no worry of spillage of overflowing wastewater, the worker can smoothly collect and transport household waste, and in particular, prevents spillage when the vehicle is running on slopes. It confirmed that it showed the advantage of shortening more than 20 minutes.

In addition, although specific embodiments of the present invention have been described above, it is obvious that the apparatus for preventing sewage leakage of the present invention may be modified and implemented in various forms by those skilled in the art.

However, such modified embodiments should not be individually understood from the technical spirit or the prospect of the present invention, and such modified embodiments shall fall within the appended claims of the present invention.

As described above, the present invention prevents the sewage generated in the process of collecting and transporting household garbage by using a compressed chariot to prevent spillage on the road during transportation, thereby preventing environmental pollution (water pollution, living odor, etc.). It will have the effect of improving the adverse effects and creating a clean urban environment.

In particular, it can be seen that the spill prevention apparatus of the present invention can be installed at a low cost by maximizing the storage capacity of the sewage while still using the existing sewage collection tank.

Along with this, the work time required for garbage collection can be shortened, thereby improving the work efficiency of the worker.
