Abstract

According to the present invention, disclosed is a manhole cleaning apparatus. If a wastewater absorption body absorbs wastewater from a manhole, a wastewater storage part on one side in a storage tank first stores the absorbed wastewater and the wastewater stored in the wastewater storage part is discharged to a cyclone filter part, a disc filter part, a first filtration filter part, a second filtration filter part and a third filtration filter part stage by stage. The wastewater is filtered five times during the procedure of staged discharge with the cyclone filter part, the disc filter part, the first filtration filter part, the second filtration filter part and the third filtration filter parts, so purified water can be obtained. The purified water is stored in a purified water storage part installed on the other side in the storage tank, and then, the stored purified water is sprayed to the manhole with high pressure to clean the inside of the manhole, so the use of water for cleaning the manhole can be minimized. Moreover, since an absorption pump and an absorption and discharge pump are operated at the same time when the wastewater absorption body absorbs the wastewater from the manhole, time for the absorption of the wastewater can be considerably shortened, and also, the wastewater stored in the wastewater storage part can be quickly discharged by the absorption and discharge pump after the completion of the manhole cleaning work, so workability and efficiency can be significantly increased.

Description

Cleaning truck for manhole with filtering device}

The present invention relates to a manhole cleaning vehicle for cleaning the inside of a manhole, and more particularly, a manhole to filter the sewage, including sludge generated during the cleaning of the manhole, and to reuse the filtered water to clean the inside of the manhole. It is about cleaning vehicles.

In general, the manhole is installed in the place where the change or direction of the pipeline is changed or the middle part of the long straight part for maintenance and repair of water / sewage pipe buried underground or underground pipe for laying electricity or communication underground. In addition, the conduit can be naturally connected through the outlet as well as the role of the passage that can be accessed by the worker.

Such manholes require periodic cleaning due to corrosion or foreign material inflow, and also clean the inside of the manholes before the worker enters the manholes to maintain and repair the electric or communication facilities that are buried. Mainly uses vacuum suction cars to spray high-pressure washing water into the manholes, and then cleans up by sucking the sewage containing sludge.

The conventional vacuum suction vehicle is divided into a water tank for storing water for high-pressure injection to clean the sludge and dirt, and a sludge tank for recovering sewage including sludge and dirt after spraying washing water, and a double tank is mounted on the vehicle. It consists of a high pressure pump and a washing water injection device for high-pressure spraying water in the water tank, and a vacuum pump for vacuum suction of sewage containing the sludge.

Manhole cleaning using a conventional vacuum suction vehicle is performed by spraying the water in the water tank with a high pressure pump using a high pressure pump to wash, and sewage collected by washing is sucked together with the sludge using a vacuum suction pump. Recover to sludge tank.

However, in the conventional vacuum suction car, when the sewage collected into the sludge tank reaches the full level, the sewage is discharged to the outside and reworked. When the water tank becomes insufficient, the water in the water tank has to be replenished. There is a problem of having to move from the cleaning work place to discharge the wastewater and supply the cleaning water for cleaning, and this takes a lot of work time and the cost of treating it separately due to the mixture of sludge and sewage is low, resulting in low economic efficiency. There is this.

Meanwhile, various techniques for cleaning the manhole have been devised.

For example, a sludge centrifugal separator for sewage manhole dredging car, which is registered in Korean Patent No. 10-1275881, has been settled, which is installed in a loading box of a vehicle and collects and stores sediments of sewers and stores sewage for sewage from the sediments. A processing apparatus, comprising: a storage means installed in the storage box of the vehicle, the storage means having a vacuum suction member, a storage tank having a storage space in which deposits are stored, by vacuum suctioning and storing deposits; and a deposit stored in the storage tank of the storage means. And a supply member connected to the reservoir for centrifuging the sludge and water in the sediment, and a separation member configured to receive the sediment supplied through the supply member and to centrifuge the received sediment to centrifuge sludge and sewage. As a means, the sludge collected from the manhole is filtered The separated over a water discharge to the outside and filtration sludges are to process and loaded separately.

However, such a prior art has a complicated configuration, such as a storage means and a centrifugal separation means, so that the manufacturing cost for the sewage treatment apparatus is increased, causing a cost burden, and space utilization is greatly increased as the space occupied by the vehicle increases. There is a problem of deterioration.

As another example, an integrated underground facility cleaning and inspection apparatus, which is registered as Korean Patent No. 10-1522658, has been devised, which includes a mobile vehicle having a loading unit and a fluid except for air by vacuum suctioning a fluid disposed in the loading unit and remaining in the underground facility. A vacuum suction tank configured to store the water, a water purifying means for receiving the vacuum sucked fluid into the vacuum suction tank, and filtering and purifying the purified water, and a water storage tank storing the purified water through the water purifying means; In a vehicle for cleaning and checking an underground facility having an injection means for injecting purified water stored in the purified water storage tank to the outside, it is disposed in the loading unit, and has a suction hose connected to a vacuum pump and introduced into the underground facility. The gas suction tank and the gas suction tank configured to vacuum suck the gas remaining in the underground facility Gas removal means having a filter for filtering and purifying the gas to be discharged, and a harmful gas detection sensor provided at the end of the suction hose to measure the concentration of harmful gas inside the underground facility. A gas sensor configured to detect and transmit the sensed data to the control means, and an inside of the suction hose provided at the end of the suction hose to acquire the image data by capturing the interior of the underground facility, and simultaneously transmitting the obtained image data to the control means. Transmitting means for transmitting the harmful gas concentration and image data of the underground facilities collected by the control means to the receiver set through the communication network, and the gas status of the underground facilities calculated by the control means through the receiver And display means for displaying image data in real time. In order to clean and check the interior space of underground facilities, the gas detection sensor and the internal photographing means recognize the state of the interior of the underground facilities to check whether the environment is accessible to the workers and to clean them in a safe location. And inspection work.

However, this conventional technique is to be purified by the purified water only by the purified water means to store the inside of the water storage tank, but the suction time of the sewage because the inhaled waste water passes through the water purification means first and then stored in the purified water storage tank The delayed problem is causing another problem of delayed working time.

As the sewage storage unit 21 is provided on one side of the storage tank 20 and the water purification unit 23 is provided on the other side of the storage tank 20, the sucked sewage is first stored in the sewage storage unit 21. The sewage is stored and stored by the cyclone filter unit 31, the disk filter unit 32, the first filtration filter unit 33, the second filtration filter unit 34, and the third filtration filter unit 35 of the present invention. Filtered in stages and stored in the purified water storage unit 23, the sewage sucked from the manhole side, such as the cyclone filter unit 31, the disk filter unit 32, the first filtration filter unit 33, Since the second filtration filter 34 and the third filtration filter 35 are filtered through five steps, the clean water required for manhole cleaning may be stored in the purified water storage unit 23, and thus the manhole cleaning process is performed. The use of wash water obtained by raw water, such as tap water, can be minimized.

The operation of the present invention made as described above will be described.

First, the dirty sewage remaining in the manhole is sucked by the sewage suction body 10 and stored in the sewage storage unit 21 provided at one side of the storage tank 20.

Thus, the sewage stored in the sewage storage unit 21 is discharged to the cyclone filter unit 31 through the sewage discharge pipe 22 of the present invention and is first filtered by the cyclone filter unit 31.

At this time, the sewage discharged through the sewage discharge pipe 22 is introduced into the cyclone filter unit 31 through the upper side of the cyclone filter unit 31, and thus the sewage is cyclone through the upper side. The reason for allowing the filter 31 to be introduced into the filter unit 31 is to easily and easily filter the sludge contained in the sewage introduced into the cyclone filter unit 31 by the centrifugal force of the cyclone filter unit 31.

The filtered water filtered by the cyclone filter part 31 as described above is connected to the other side of the primary filtration water discharge pipe 41 through a primary filtration water discharge pipe 41 connected to one side of the cyclone filter part 31. The disk filter unit 32 is connected to the inside of the disk filter unit 32 and filtered by the disk filter unit 32.

Since the filtrate is filtered by the filtration filter 35 in five stages, it is possible to obtain clean water for washing the manhole, and the cyclone filter 31, the disk filter 32, and the first filtration filter ( 33), the purified water obtained by the second filtration filter 34 and the third filtration filter 35 in five stages, the fifth filtration water discharge pipe connected to one side of the third filtration filter 35 Through the 45, the other side of the fifth filtration water discharge pipe 45 is introduced into and stored in the purified water storage unit 23 provided on the other side inside the storage tank 20.

In this way, the purified water stored in the purified water storage unit 23 is the cyclone filter unit 31, the disk filter unit 32, and the first by the high-pressure injection unit 50 connected to the purified water storage unit 23. The purified water filtered by the filtration filter unit 33, the second filtration filter unit 34, and the third filtration filter unit 35 may be injected at a high pressure into the manhole to wash the inside of the manhole.

The filtration process may be repeatedly performed to clean the inside of the manhole. When the manhole cleaning is completed, the first shunt valve 60 provided in the sewage discharge pipe 22 is operated to operate the sewage discharge pipe 22. Blocking the discharge of sewage to the cyclone filter unit 31 through the cyclone filter unit 31, the disk filter unit 32, the first filtration filter unit 33, the second filtration filter unit 34 In order to prevent filtration of filthy water by the third filtration filter part 35, the filthy water stored in the filthy water storage unit 21 may be drained out through the effluent drainage pipe 61 to be treated. The sewage drained out through the 61 is the cyclone filter unit 31, the disk filter unit 32, the first filtration filter unit 33, the second filtration filter unit 34, and the third filtration filter unit ( The manhole is discarded after washing the inside of the manhole by purified water filtered in 5 steps. Since the sewage in the filtered state is discarded, not the sewage in the state containing sludge before the washing operation, it is possible to prevent the environmental pollution by the waste water discarded.

When the manhole cleaning is completed, the purified water stored in the purified water storage unit 23 may be drained out through the purified water drain pipe 62 connected to the purified water storage unit 23.

In this case, it is possible to prevent the environment from being polluted by discarding the purified water stored in the purified water storage unit 23.
