Concrete truck washing wastewater treatment device

Abstract

This utility model relates to a wastewater treatment device for concrete truck washing. In actual production, when wastewater from concrete truck washing needs treatment, it can be introduced into a sedimentation tank through a first inlet for sedimentation. Subsequently, silt and flocculent matter settle to the bottom of the sedimentation tank, separating from the water. Then, a lifting assembly is activated, lowering the suction head to the water surface in the sedimentation tank. Next, a pumping unit is activated, drawing the separated water from the sedimentation tank into a pumping pipe through the suction head. The water then enters a storage tank through a second inlet for collection. Operators can observe the sedimentation process through a viewing window and adjust the suction head's descent position accordingly to ensure clearer water. This allows for better wastewater treatment and recycling, reducing water waste during concrete truck washing and lowering production costs.

Description

Technical Field

[0001] This utility model relates to the field of concrete truck washing wastewater treatment technology, and in particular to a concrete truck washing wastewater treatment device. Background Technology

[0002] After a concrete mixer truck completes its transport mission and returns to the site, it needs to clean the concrete residue inside the mixing tank. The current cleaning method is to add water to the mixing tank for rinsing, which consumes a lot of water. At the same time, the wastewater produced contains cement, sand, gravel and various admixtures, so direct discharge will cause environmental pollution.

[0003] Traditional wastewater treatment requires separating sand and gravel from the wastewater before further treatment. Due to the large volume of wastewater, traditional treatment devices cannot effectively recycle the wastewater, resulting in significant waste of water resources and increased production costs.

[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figures 1 to 4 As shown, a concrete truck washing wastewater treatment device of the present invention includes a sedimentation tank 2, a frame 8 and a water resource recovery mechanism 7. The water resource recovery mechanism 7 is connected to the upper part of the sedimentation tank 2 through the frame 8. The upper part of the sedimentation tank 2 is provided with a first water inlet, and the outer side of the sedimentation tank 2 is provided with a viewing window 1.

[0029] The water resource recycling mechanism 7 includes a lifting assembly, a pumping assembly, and a water storage tank 704. The lifting assembly is connected to the frame 8. One end of the lifting assembly is driven to the pumping assembly, and the other end of the pumping assembly is connected to the water storage tank 704.

[0030] The water pumping assembly includes a pumping component 706, a pumping pipe 707, and a suction head 703. The lifting assembly is driven to the suction head 703. The suction head 703 is connected to one end of the pumping component 706 through the pumping pipe 707. A second water inlet is provided on the upper part of the water storage tank 704. The other end of the pumping component 706 is connected to the second water inlet.

[0031] The working principle of this utility model is as follows: In actual production and use, when it is necessary to treat the wastewater from washing concrete trucks, the wastewater can be introduced into the sedimentation tank 2 through the first inlet for sedimentation. Subsequently, mud, sand and flocculent matter settle to the bottom of the sedimentation tank 2, and the mud and sand are separated from the water. Then, the lifting component is operated, which drives the suction head 703 to descend to the water surface in the sedimentation tank 2. Then, the pumping component 706 is operated, which allows the water separated inside the sedimentation tank 2 to be pumped into the pumping pipe 707 through the suction head 703. Then, it enters the water storage tank 704 through the second inlet for collection. The operator can observe the sedimentation situation in the sedimentation tank through the viewing window 1 and adjust the descent position of the suction head 703 according to the sedimentation situation so that the pumped water can be clearer.

[0032] Furthermore, the lifting assembly includes a screw jack 701, a slide rod 705, and a lifting plate 702. Both sides of the lifting plate 702 are provided with slide rods 705. The frame 8 is provided with sliding holes adapted to the slide rods 705. One slide rod 705 is slidably connected to one of the sliding holes. The upper part of the screw jack 701 is connected to the frame 8, and the lower part of the screw jack 701 is linearly driven connected to the lifting plate 702. The water suction head 703 is located at the lower part of the lifting plate 702.

[0033] As can be seen from the above description, when it is necessary to extract and recycle the separated clear water, the screw jack 701 can be operated, so that the screw jack 701 drives the suction head 703 to descend through the lifting plate 702, so that the suction head 703 moves to a suitable position, and then the clear water separated in the sedimentation tank is pumped into the water storage tank 704 for collection.

[0034] Furthermore, it also includes a scale 5, which is provided from top to bottom on one side of the viewing window 1.

[0035] As can be seen from the above description, it is beneficial to better observe the sedimentation situation in the sedimentation tank 2. The boundary between the clear water and the sediment can be seen more intuitively through the scale 5, which makes it easier for the suction head 703 to move to a suitable position for pumping water.

[0036] Furthermore, it also includes a valve body 10, and a first water outlet is provided at the lower part of the sedimentation tank 2, with the valve body 10 disposed inside the first water outlet.

[0037] As can be seen from the above description, when it is necessary to discharge the sediment, the first outlet can be opened through the valve body 10, and then the sediment in the sedimentation tank 2 can be discharged to the outside of the device through the first outlet.

[0038] Furthermore, it also includes a feeding assembly, with one feeding assembly arranged opposite to each other on both sides of the first outlet, and the feeding assembly is connected to the sedimentation tank 2;

[0039] The feeding assembly includes a linear drive 4 and a pusher plate 9. The pusher plate 9 is slidably connected to the interior of the sedimentation tank 2, and the linear drive 4 is linearly driven connected to the pusher plate 9.

[0040] As can be seen from the above description, when it is necessary to better discharge the sediment, the linear drive 4 can be operated to drive the push plate 9 to push the sediment in the sedimentation tank 2 to the first outlet for discharge.

[0041] Furthermore, it also includes a water pump 6, and a second water outlet is provided at the lower part of the water storage tank 704, and the water pump 6 is provided on the second water outlet.

[0042] As can be seen from the above description, when the water in the water storage tank 704 needs to be used, the water pump 6 can be run to pump the water in the water storage tank 704 out through the second water outlet.

[0043] Furthermore, including support feet 3, several support feet 3 are fixedly connected to the bottom of the sedimentation tank 2.

[0044] As can be seen from the above description, this is conducive to more stable operation of the device and allows the sediment to be discharged more effectively from the first outlet.

[0045] Furthermore, it also includes a PLC controller, which is electrically connected to both the lifting assembly and the pumping assembly.

[0046] As can be seen from the above description, it is beneficial to adjust the parameters of the concrete truck cleaning wastewater treatment device through the PLC controller, and to make it more convenient for operators to operate the concrete truck cleaning wastewater treatment device.
