Description

DETAILED DESCRIPTION OF THE INVENTION Mutojia relates to a sewage discharge device that is capable of discharging only sewage out of sludge water sucked into a tank in sludge soil.

Generally, in the case of sludge (1), since a large amount of sludge is stored in the tank, only the sewage is separated from the sucked sludge water and then discharged.

By the way, in a conventional sewage discharge device, a perforated plate is installed as a partition wall in the front part of a tank having an opening/closing M at the rear, and a sewage chamber is formed in a curved part of the tank by the partition wall, and sewage is sucked into the tank. 11 so that the sewage out of the FC sludge water is led to the sewage chamber through the partition wall, and the sewage is discharged from the sewage chamber to the outside of the tack.

However, cleaning the sewage room requires a great deal of labor and time, as it must be carried out after the sludge in the tank has been discharged and the first wall of the ward has been removed from the tank.

In order to eliminate the drawbacks mentioned above, the sewage chamber is provided on the opening/closing lid side, so that the sewage chamber can be opened at the same time as the opening/closing lid is opened.

Hereinafter, the F embodiment will be explained with reference to the drawings. +114- is a sludge truck, and the sludge truck (1) is equipped with a tank (3) and a vacuum pump (4) on the N stock (2).

The tank (3) has a cylindrical tank body (5) and an opening/closing lid (7) that closes an opening part (6) at the rear of the tank body (5).
).

@a The tank body (5) is equipped with a vacuum pump + 41, a hose (8) for communicating with the IC, and a suction pipe (9), and furthermore, the tank body (5) is equipped with a hydraulic pressure shaft that is pivotally supported on the vehicle body f21 side. The front two opening/closing lids (7), which are supported backwards by the cylinder 11D14, are bowl-shaped and both have a vertical bracket at the top (111) to allow upward rotation. Changed VC cylinder: / 'y (X (Hydraulic cylinder 02 with a shaft support force on the 51 side) ic and mounted on the upper side (b).

Fix a pair of left and right partition walls (131+131) in the vertical direction on the inner surface of the gf+ opening/closing lid,
It has a 1131 li cross-section shape, and a seal plate (141 (14)) is stretched on the flat part facing the opening (6) side.

(15) is a separation plate that prevents passage of sludge;
15) Seal board! 141 +141 to close the space between the pair of C compartment walls 13 (13), thereby forming a sewage chamber (16) on the opening/closing lid (7) side.

11 is fixed to the shaft (22) near the opening (6) at the upper part of the tank (5) so that the separating plate (15) is suspended inside the tank (5). It has become.

Among the hooks t21+ +211, the shaft C2)
A horizontal part t23+ +231 is formed at the part that comes into contact with (-

In addition, a pair of drawing boards 11 force (the lower part of 1η is the partition wall 1131

The opening/closing lid (7) is rotated upward fl, 7' (
At this time, the separation plate f15) can also be lifted up in a state where it is optically separated from the opening/closing lid 17).

(25) is an auxiliary plate removably provided at the 'F part between the pair of partition walls (13+ (131), and this auxiliary plate τ circle -F part plate of the separation plate (15)! 19) 'I: surface is tank +
31! Even if it is separated by a light distance from the 79th plane, it is possible to prevent sludge from entering the sewage chamber 116).

(26) is a discharge pipe for discharging sewage from the sewage room (1G) to the outside of the tank (3), and this discharge pipe + 26)t/'i opening/closing lid (7)K is provided, and an opening/closing valve is installed in the middle. There is an intervention.

Note that the structure of the dividing plate II'i is not limited to the structure as in the embodiment, and any structure that prevents sludge from entering the sewage chamber can have the same effect.

Uninvented (r'i) When we explain the operation next with the structure as in
In the state shown by the solid line in the figure, operate the vacuum pump +41 and tank 1.
3) After reducing the pressure of the tank to a low pressure, sludge water is sucked into the tank (3) from the suction piping (9).

The sludge in the sucked sludge water is separated by a separation plate! 151 I
Since entry into the sewage chamber +16 from C is blocked, the sewage collects in the tank i' body (5) and flows through the separation plate f15.
1? The water passes through and is stored in the dirty water chamber (16).

At this time, the pressing force of the sludge water acts on the molecule @ plate 151, and the hook f21 that hangs the separation plate f15)
Since the horizontal section (213) is formed with a horizontal section (231), the separation plate (5) is pressed against the sealing plate (141) of the partition wall (131+131) to ensure the sealing of the sewage chamber (16). It looks like this.

The sewage contained in the sewage chamber +]61[/C'rL is discharged by opening the on-off valve (27) of the discharge pipe (26+).

By repeating the above operations, only sludge can be efficiently stored in the tank (3).

Next, while discharging the sludge, a hydraulic cylinder 11 (J21'f
l-Extend and rotate the opening/closing lid (7) upwards to open the tank,
Open the body +5+ opening 1 part (6).

At that time, since the lower part of the separation plate (19) is connected to the opening/closing lid j71 Ill by the chain (241+2411),
The separation plate (15) can also be rotated upward together with the opening/closing lid (7) to the dashed line in FIG. 2, allowing the opening part (6) to be fully opened.

Furthermore, since the opening/closing lid (7) and the separation plate 115) have different centers of rotation, the front surface of the wastewater chamber (16) is also opened.

After that, extend the hydraulic cylinder jig (10) to remove the tank i.
3) Drain the sludge inside the tank body (5) by tilting the hole.

After the sludge has been discharged, the tank body (
5) Inside (C) Spray water to clean. Also, open/close lid (7)
Since the separation plate 115) of the wastewater chamber (16) on the side is also automatically opened, the wastewater chamber (16) can be left in the open state.
Prisoners can be cleaned by spraying them with water.

At that time, a pair of partition walls (13)! 13) By removing and peeling off the auxiliary plate (251) that is engaged between the two, the cleaner can be removed more easily.

As described above, the great invention forms a sewage chamber on the opening/closing lid side, suspends the separation plate, which is a part of forming the sewage chamber, on the tank body side, and at the same time, separates the separating plate and the opening/closing lid side. Since the connector is connected by a chain, there is no need to manually move the dividing plate to clean the inside of the tank and the sewage chamber (cleaning inside the tank can be done in a short time with little effort). be able to.
