[0030] This application provides a concrete mixer truck cleaning water recycling and treatment system, such as... Figure 1As shown, the concrete mixer truck washing water recycling and treatment system includes: a first treatment unit 1, a second treatment unit 2, and a third treatment unit 3. The first treatment unit 1 is equipped with a separation component, which washes the waste concrete powder screen in the mixer truck with washing water, and then sends the washed water back into the first treatment unit 1. The second treatment unit 2 is connected to the first treatment unit 1, and the washing water treated by the first treatment unit 1 enters the second treatment unit 2. The second treatment unit 2 is equipped with a transfer component, which transports the washing water from the second treatment unit 2 to the target location. The third treatment unit 3 is connected to the second treatment unit 2 and also connected to the first treatment unit 1. A portion of the washing water treated by the second treatment unit 2 enters the third treatment unit 3, where it undergoes further treatment before returning to the first treatment unit 1.

[0031] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the first processing unit 1 includes a sand and gravel separator 11, which is equipped with a separation component to separate sand, stones and other materials from the washing water.

[0032] For example, the first processing unit 1 can be configured to include a sand and gravel separator 11, which can be equipped with a separation component to separate large-sized sand, stones and other materials attached to the washing water.

[0033] For example, the separation assembly can be configured to include a first screen 111 and a second screen 112. The sand and gravel separator 11 has a water inlet at its top, through which waste concrete powder from the concrete mixer truck is washed with cleaning water. The washing water is then pumped into the sand and gravel separator 11 through the water inlet. The first screen 111 can be positioned closest to the water inlet within the sand and gravel separator 11. The first screen 111 has filter holes, through which large stones are separated.

[0034] A first conveying component can be set on the sand and gravel separator 11 at a position corresponding to the first screen 111. For example, the first screen 111 can be a vibrating screen. The large stones filtered out on the first screen 111 are conveyed to the side of the sand and gravel separator 11 by the vibration of the vibrating screen. A collection structure and a conveying structure can be set on the side of the sand and gravel separator 11 to separate, collect and convey the large stones.

[0035] In another example, the second screen 112 can be set below the first screen 111. The size of the filter holes of the second screen 112 can be smaller than the size of the filter holes of the first screen, that is, smaller sand can fall through the first filter screen onto the second filter screen. The sand separator 11 can be equipped with a second conveying component. For example, the second conveying component can be a conveyor belt structure or other structure with conveying function. The sand filtered on the second screen 112 is conveyed to the corresponding position through the second conveying component.

[0036] For example, the sand and gravel separator 11 has a discharge port and a collection bin is provided below the discharge port. The second conveying component pushes the sand on the second screen 112 from the discharge port into the collection bin.

[0037] In the above embodiments, since a first processing mechanism 1 is provided, stones, sand and other materials in the cleaning water can be separated and reused, which saves resources on the one hand and facilitates subsequent treatment of the cleaning water on the other.

[0038] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the second treatment unit 2 includes a sedimentation tank 21, which is connected to the outlet of the sand and gravel separator 11. A stirring tank 22 is connected to the top of the sedimentation tank 21, and a transfer component is provided in the stirring tank 22.

[0039] For example, the second processing unit 2 can be configured to include a sedimentation tank 21, wherein the sedimentation tank 21 is provided with a structure corresponding to the outlet of the sand and gravel separator 11, so that the water flow in the sand and gravel separator 11 can enter the sedimentation tank 21. A stirring tank 22 can be provided on one side of the sedimentation tank 21, and a notch is provided at the top of the sedimentation tank 21 near the stirring tank 22. This configuration allows water with fewer impurities from the upper part of the stirring tank 22 to be transported into the stirring tank 22.

[0040] Staff can clean the sediment at the bottom of sedimentation tank 21 regularly or irregularly, and the cleaned sediment will be disposed of according to the actual situation.

[0041] Another example, such as Figure 5 As shown, a transfer component can be set above the mixing tank 22. The transfer component can be configured to include a motor 221. For example, a cover plate can be installed above the mixing tank 22, and the motor 221 can be installed on the cover plate. The output shaft of the motor 221 is connected to a stirrer 222, which can be a spiral blade. The stirrer 222 mixes the liquid in the mixing tank 22 evenly and transports it.

[0042] It is understood that the number of motors 221 can be two or three. This application embodiment does not specifically limit the number of motors 221, and can set it according to the actual situation, for example, according to the size of the mixing tank 22.

[0043] In another example, the mixing tank 22 can be connected to a first water outlet pipe and a second water outlet pipe. Both the first and second water outlet pipes are connected to water pumps. The liquid in the mixing tank 22 is transported to other processing workshops through the first water outlet pipe, for example, to the commercial concrete plant 4, so that the cement slurry can be reused.

[0044] Furthermore, the liquid in the mixing tank 22 can be transported to the corresponding component of the third processing unit 3 through the second water outlet pipe for secondary processing of the liquid in the mixing tank 22.

[0045] In the above embodiment, the sedimentation tank 21 is provided to settle the liquid flowing out of the sand and gravel separator 11 and further separate the sand and other substances in the liquid; the mixing tank 22 is provided to distribute the slurry, with one part of the slurry used in other processes during concrete production and the other part transferred to the third processing unit 3 for further processing; the transfer component is provided to mix the slurry in the mixing tank 22, facilitating subsequent processing.

[0046] In some embodiments of this application, such as Figure 6 As shown, the third processing unit 3 includes a filter press 31. The inlet of the filter press 31 is connected to the second outlet pipe, and the incoming cleaning water is filtered through the filter press 31.

[0047] For example, the third processing unit 3 can be configured to include a filter press 31. The inlet of the filter press 31 can be connected to the second outlet pipe. After the slurry in the mixing tank 22 enters the filter press 31, the slurry is further processed by the filter press 31.

[0048] The filter press 31 is a mechanical device that uses a special filter medium to apply pressure to the material, causing the liquid to seep out; it belongs to the category of solid-liquid separation equipment. When the slurry in the mixing tank 22 enters the filter press 31, the filter press 31 compresses the mud and sand in the slurry into a dry cake 311 and seeps out the liquid from the slurry.

[0049] Furthermore, a collection box 33 or other parts with collection functions can be provided below the filter press 31. Taking the collection box 33 as an example, the dry cake 311 pressed out by the filter press 31 can be collected through the collection box 33.

[0050] In another example, the third processing unit 3 can be configured to include a clear water tank 32. The clear water tank 32 can be connected to the inlet of the sand and gravel separator 11 via a pipeline, and the clear water tank 32 can be connected to the filter press 31 via a pipeline. The filter press 31 filters out the liquid from the slurry and transports it to the clear water tank 32 through a corresponding pipeline. Then, the clear water in the clear water tank 32 is transported to the sand and gravel separator 11 for reuse through a pipeline.

[0051] In the above embodiments, since a filter press 31 is provided, part of the slurry in the mixing tank 22 is further processed by the filter press 31 to separate the solid and liquid; and the separated clear water is collected and reused by the clear water tank 32, thus saving resources.

[0052] The following describes the usage process of the concrete mixer truck cleaning water recycling and treatment system provided in this application. During use:

[0053] S100: First, the waste concrete in the concrete mixer truck is washed with washing water. The washing water is then transported to the sand and gravel separator 11. Large stones in the washing water are separated to a designated location by the first screen 111 and the first conveying assembly. Smaller sand in the washing water is separated to a designated location by the second screen 112 and the second conveying assembly. Then, the washing water flows out from the outlet of the sand and gravel separator 11 into the sedimentation tank 21.

[0054] S200: The washing water after being treated by the sand and gravel separator 11 enters the sedimentation tank 21. As the water level in the sedimentation tank 21 rises, the clearer washing water in the upper part of the sedimentation tank 21 flows into the mixing tank 22. The motor 221 is started, and the output shaft of the motor 221 drives the agitator 222 to rotate. The agitator 222 mixes the slurry in the sedimentation tank 21 evenly, and the evenly mixed slurry is transported to the commercial concrete plant 4 through one pipeline for reuse, and the evenly mixed slurry is transported to the filter press 31 through another pipeline for further treatment.

[0055] S300: After the slurry in the mixing tank 22 enters the filter press 31, the filter press 31 makes the mud and sand in the slurry into dry cake 311. While making the dry cake 311, the filter press 31 can separate the clear water from the slurry and transport the clear water to the clear water tank 32 through the pipeline. Then, the clear water in the clear water tank 32 is transported to the sand and gravel separator 11 and / or concrete mixer truck for further processing through the corresponding pipeline.
