[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 9 , the utility model provides a technical solution for a printing and dyeing wastewater treatment device.

[0033] A printing and dyeing wastewater treatment device, comprising:

[0034] A box body 1 is provided with a filter cavity 2 with an opening facing upwards, a water inlet pipe 36 is provided at the front end of the box body 1, and a water outlet pipe 37 is provided at the rear end;

[0035] A plurality of filter screens 3 are arranged in the filter cavity 2, and the filter screens 3 are arranged in sequence along the length direction of the box body 1;

[0036] A vertical moving device, the vertical moving device is fixed on the outside of the box body 1;

[0037] A transverse moving device, the transverse moving device is installed on the vertical moving device, and the vertical moving device is used to drive the transverse moving device to move horizontally;

[0038] The spraying device includes a spraying bracket 4, which is connected to the transverse moving device. A spraying vertical rod 5 is fixed to the spraying bracket 4. A spraying horizontal rod 6 is fixed to the lower end of the spraying vertical rod 5. A spraying cavity 7 is arranged in the spraying horizontal rod 6. A plurality of spraying holes 8 are arranged on the side walls on both sides of the spraying cavity 7. The spraying cavity 7 is connected to a water source.

[0039] like Figure 7 As shown, a connecting hole 38 communicating with the spray cavity 7 is provided on the spray vertical rod 5 , and water is supplied to the spray cavity 7 through the connecting hole 38 .

[0040] The waste water enters the filter cavity 2 through the water inlet pipe 36, and is discharged from the water outlet pipe 37 after being filtered by each filter screen 3. When the filter screen 3 needs to be cleaned, the waste water stops entering the water inlet pipe, and the water in the filter cavity 2 is drained. Then the transverse movement device drives the spray cleaning bracket 4 to move transversely, and drives the spray cleaning cross bar 6 to the side of the filter screen 3 that needs to be cleaned. Then the vertical movement device drives the spray cleaning cross bar 6 to move up and down. In this process, water from the water source is pumped into the spray cleaning cavity 7 by the water pump, and then water is sprayed out from the spray cleaning hole 8. The sprayed water sprays the dirt on the filter screen 3. During the spray cleaning process, the vertical movement device drives the spray cleaning cross bar 6 to move up and down, so that the same side of the filter screen 3 can be sprayed more cleanly. After the side is sprayed clean, the spray cleaning cross bar 6 is driven by the transverse movement device and the vertical movement device to spray the other side of the filter screen 3. The filter screen 3 is very convenient to clean.

The lifting device is used to drive the lifting rod 10 to move up and down.

[0042] Since a plurality of spray holes 8 are provided on the side walls of both sides of the spray cavity 7, when spraying the filter screen 3 on one side, the shielding rod 12 on the other side is driven to move so as to be in a shielding state, thereby shielding the spray holes 8 on the other side, so that the water pressure from the spraying side is greater and the spraying is cleaner. The lifting device is used to control the movement of the shielding rod 12 to control which side the water is sprayed from, so that the water pressure from the spraying side is greater.

When a lifting rod 10 needs to be driven to move downward, the rotating motor 14 drives the pressing rod 17 to rotate above the pressure rod 18 of the lifting rod 10, and then the electric push rod 13 drives the pressing rod 17 to move downward, and the pressing rod 17 drives the pressure rod 18 to move downward, thereby driving the lifting rod 10 to move downward, so that the shielding rod 12 at the lower end of the lifting rod 10 shields the water spray hole to complete the shielding. When shielding is not needed, the electric push rod 13 drives the pressing rod 17 to move upward, and the reset spring 15 drives the lifting rod 10 to move upward, so that the shielding rod 12 is not shielded.
