This sludge tank 110 is to be able to temporarily store the sludge in the sump to be cleaned. The sludge tank 110 is connected to the first pump 120. The first pump 120 is for pumping the sludge in the sump to be cleaned to the sludge tank 110. The first pump 120 is a vacuum pump for discharging the air in the sludge tank 110 to the outside so that the negative pressure is applied to the sludge tank 110. Of course, in some cases, generally used pumping pump may be used as the first pump 120. The sludge tank 110 is provided with a manhole 112 that can be accessed by a person to clean the inside of the tank and a drain valve 114 for discharging water, etc., washed out of the tank.

As shown, the vehicle 100 is provided with a frame 130 having a rail 132. As shown in FIG. 2, the rails 132 are installed at a predetermined height in parallel with a pair at intervals. As the rail 132, a channel having a “c” cross section is suitable. On the rail 132, the auxiliary rail 134 is formed to protrude upward. This auxiliary rail 134 is for guiding the movement of the pressure plate 140 described later. A stopper 142 is provided at one end of the rail 132. This is to support the opposite side when the filter plate 150 to be described later is pressed by the pressure plate 140 so that each filter plate 150 can be in close contact with the filter cloth 160 therebetween.

As illustrated, a plurality of filter plates 150 surrounded by the filter cloth 160 on both sides thereof are mounted on the rail 132 so as to be movable. The internal structure of the filter plate 150 surrounded by the filter cloth 160 will be described in more detail later with reference to FIGS. 3 and 4.

The pressure plate 140 is to close the filter plate 150 surrounded by the filter cloth 160 to provide a space for accommodating sludge between the respective filter plates 150. That is, when the pressure plate 140 pushes the filter plate 150 surrounded by the filter cloth 160 at one edge toward the filter plate 150 at the opposite end, the filter plate 150 surrounded by both sides of the filter cloth 160 is the filter cloth. The spacer 160 is in close contact with each other along an edge thereof, and a space in which sludge is accommodated is formed between each filter plate 150. The spaces formed between the respective filter plates 150 are connected to each other through the sludge through-hole 152 formed in each filter plate 150 and the hole 162 formed in the filter cloth 160.

As described above, the pressure plate 140 may use the hydraulic device 170 having the cylinder 172.

The sump cleaning vehicle 100 according to the present invention includes a second pump 180. The second pump 180 injects and pressurizes the sludge in the sludge tank 110 into the space formed between each filter plate 150 so that the water contained in the sludge is filtered out through the filter cloth 160 to escape to the outside. It is to make it possible. As the second pump 180, a pressure pump is suitable.

3 is a cross-sectional view of the filter plate surrounded by the filter cloth, Figure 4 is a cross-sectional view showing a state in which the filter plate surrounded by the filter cloth is pressed by the pressure plate.

As can be seen in FIGS. 3 and 4, an empty space 154 is formed inside the filter plate 150. An edge 156 is formed along the outer edge of the filter plate 150, and recesses 158 are formed on both sides of the edge 156 to be concave. The concave portion 158 provides a space for injecting sludge, and a plurality of inflow holes 151 at the bottom thereof to allow water that has passed through the filter cloth 160 to enter the empty space 154 therein. Is provided. In addition, the lower end of the filter plate 150 is provided with a discharge hole 153 for discharging water introduced into the inlet hole 151. The water discharged to the discharge hole 153 is discharged through the valve 157 after moving to the edge along the lower channel 155. The side of the filter plate 150 is formed with a locking projection 159 is caught on the rail 132.

As shown, the filter plate 150 is covered with the filter cloth 160. The filter cloth 160 surrounds both sides of the filter plate 150. This filter cloth 160 is intended to allow only the water contained in the sludge to pass through.

The process of cleaning the sump using the sump cleaning vehicle 100 according to the present invention is as follows.

First, the sludge stored in the water collection tank is pumped up to the sludge tank 110 using the first pump 120. On the other hand, the hydraulic device 170 is driven to bring the filter plates 150 surrounded by the filter cloths 160 mounted on the rails 132 with the pressure plate 140 to be in close contact with each other. Accordingly, the sludge receiving space 105 by the recess 158 is formed between the filter plates 150. In this state, the sludge receiving space 150a is connected to each other through the sludge passing hole 152.

After the above process, the second pump 180 is driven to inject sludge temporarily stored in the sludge tank 110 into the sludge accommodating space 150a formed between each filter plate 150. Accordingly, the sludge is sequentially passed through the sludge passing holes 152 of each filter plate 150 to the innermost sludge accommodating space 150a, thereby filling the entire sludge accommodating space 150a. As the sludge is injected into the sludge accommodating space 150a sufficiently by the second pump 180, the internal pressure increases, and in this state, the water is filtered through the filter cloth 160, the inlet hole 151, the internal space 154, and the discharge. Out through the ball 153, the solid residue is left in the sludge storage space (150a) in a cake state.

After a certain time, the hydraulic device 170 is driven to retreat the pressure plate 140, and then each filter plate 150 is moved one by one to spread the gaps between the filter plates 150, thereby remaining solid wastes remaining in a cake state therebetween. Shake it out, put it in a bag and transfer it to the required place for disposal.

By repeating the above process, sludge of large tank can be treated.

5 is a cross-sectional view illustrating a modification of FIG. 4.

In some cases, an air pipe 200 connected to the inner empty space 154 may be installed at the innermost filter plate 150, and the air pipe 200 may be connected to the air pump 210 to constitute the present invention. . As the air pump, the first pump 120 may be used, or a separate air pump 210 may be further installed. In this case, when the sludge is injected into the sludge accommodating space 150a by the second pump 180, the sludge is not smoothly injected to the innermost filter plate 150. That is, before the sludge is injected into the sludge accommodating space 150a or in the process of being injected, negative pressure is applied to the sludge accommodating space 150a so that the sludge can be sufficiently injected to the innermost space. In addition, when the sludge is sufficiently injected, the internal pressure may be increased by blowing air into the sludge accommodating space 150a. The rest is the same as described previously.

As described above, the water tank cleaning vehicle according to the present invention can move to a place where the water tank needs to be cleaned and directly remove water from the sludge of the water tank at the site, thereby reducing the time and effort of transporting the sludge containing a large amount of water. It allows for savings.

In addition, the negative pressure is applied to the sludge storage space through the air pipe connected to the vacuum pump so that the sludge can be smoothly injected to the innermost filter plate, and when the sludge is sufficiently filled in the sludge storage space, air is supplied to the sludge storage space. By increasing the pressure of the sludge storage space by blowing, the dewatering rate of the sludge can be increased.
