Description

Technical Field

[0001] This application relates to the technical field of concrete transportation equipment, and particularly relates to a water treatment pool for cleaning a concrete mixer truck. Background Art

[0002] At present, the concrete used in the construction industry is usually mixed in a concrete mixing plant and then transported to the construction site by a concrete mixer truck. Currently, in order to prevent sludge or concrete from adhering to the vehicle and being carried onto the road, it is necessary to wash the outside of the concrete mixer truck. At the same time, in order to prevent concrete from remaining in the tank, after the discharge of the concrete mixer truck is completed, it is also necessary to use water to wash the inside of the concrete tank. These waste waters are rich in a large amount of stone particles and fine sand. If directly discharged, it will cause waste of resources, and at the same time, it is easy to block the drainage pipeline. Moreover, for many construction sites in the construction stage, their water supply facilities are not yet operational. Therefore, some facilities for recycling waste water have been designed. For example, a Chinese patent with the application number 202020369124.8 discloses a concrete waste water precipitation and reuse device, which includes a primary filter tank, a flocculation sedimentation tank, and a reuse sedimentation tank that are connected in sequence. A plurality of hollow sealed balls are fixedly arranged on the pool wall of the flocculation sedimentation tank. The plurality of sealed balls are distributed along the height of the flocculation sedimentation tank. A hollow receiving ball is slidably arranged inside the sealed ball. The sealed ball is provided with a liquid inlet and a liquid outlet that communicate with the inner cavity of the receiving ball. The receiving ball is provided with a conversion port that communicates with its interior. The conversion port is arranged opposite to the liquid inlet. A floating rod is fixedly connected to the outside of the receiving ball. The primary sedimentation tank of this facility mainly filters the coarse and fine aggregates in the washing water through a filter plate. However, the content of aggregates in the waste water is relatively large, and it is easy to block the filter plate after long-term use, and regular maintenance is required. The aggregates are mostly sand and gravel, which are not easy to clean after being blocked. Therefore, a water treatment pool for cleaning a concrete mixer truck is needed. In the separation hopper of this pool, the aggregates in the washing water are left in the separation hopper through filtration and sedimentation, which can prevent blockage, facilitate the staff to clean the filter screen, and the separation hopper can be lifted from the treatment pool, which is convenient for cleaning and recycling the aggregates in the separation hopper and avoids waste of resources. Summary of the Utility Model

[0003] In order to solve the above problems, this application proposes a water treatment pool for cleaning a concrete mixer truck. In the separation hopper of this pool, the aggregates in the washing water are left in the separation hopper through filtration and sedimentation, which can prevent blockage, facilitate the staff to clean the filter screen, and the separation hopper can be lifted from the treatment pool, which is convenient for cleaning and recycling the aggregates in the separation hopper and avoids waste of resources.

[0004] This application is achieved through the following technical solutions:

[0005] The present application provides a cleaning water treatment tank for a concrete mixer truck, comprising: a treatment tank body, a separation hopper, and a limiting plate. A slope portion is provided on one side of the treatment tank body, the separation hopper is installed on the slope portion, the limiting plate is installed in the middle of the treatment tank body, one side of the separation hopper is closely attached to the side of the limiting plate, and the bottom of the separation hopper is in contact with the bottom of the treatment tank body; the inner cavity of the separation hopper is separated into a gravel filtration tank and a fine sand sedimentation tank by a partition plate. A communication groove is provided at the lower part of the partition plate, the gravel filtration tank and the fine sand sedimentation tank are communicated through the communication groove, and a filter screen is provided on the communication groove. An overflow port is provided at the upper part of the fine sand sedimentation tank.

[0006] Further, drainage grooves are provided on both sides of the fine sand sedimentation tank. A plurality of through holes are provided on the side of the drainage groove, and a geotextile layer is provided on the inner wall of the drainage groove. The lower part of the drainage groove is communicated with the treatment tank body.

[0007] Further, a guide plate is provided at the installation position of the filter screen in the fine sand sedimentation tank, and the guide plate is tilted upward by 20° to 40°.

[0008] Further, the aperture of the filter screen is 5 mm to 10 mm.

[0009] Further, sliding rods are provided on both sides of the separation hopper. Both ends of the sliding rods are fixedly connected to the separation hopper, and sleeves are installed on the sliding rods. The sleeves are connected to each other by a cross bar, and a hanging ring is provided on the cross bar.

[0010] Further, a locking bolt is provided on the sleeve. One end of the locking bolt passes through the sleeve and presses tightly on the sliding rod.

[0011] The beneficial effects of the present application: By providing a separation hopper on the water inlet side of the treatment tank body, after the cleaning water of the concrete mixer truck flows into the separation hopper and passes through the filter screen to filter out larger stone particles, other fine sand will settle at the lower part of the fine sand sedimentation tank due to the slow flow rate, thereby separating the sand and gravel in the cleaning water. The separated sand and gravel can be continuously used for the production of concrete. After the wastewater enters the treatment tank body, the impurities in the water can be precipitated by flocculation precipitation, and the supernatant can be reused for cleaning the concrete mixer truck, so that the cleaning water can be reused, reducing the consumption of water resources and facilitating the use at construction sites where water intake is inconvenient.

Specific embodiments

[0017] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Among them, the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings).

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the said features. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0020] As Figures 1 to 4 shown, an embodiment of the present utility model provides a water treatment tank for cleaning a concrete mixer truck, including: a treatment tank body 1, a separation hopper 2, and a limit plate 3. A slope portion is provided on one side of the treatment tank body 1. The separation hopper 2 is installed on the slope portion, and the limit plate 3 is installed in the middle of the treatment tank body 1. One side of the separation hopper 2 is closely attached to the side surface of the limit plate 3, and the bottom of the separation hopper 2 is in contact with the bottom of the treatment tank body 1. The inner cavity of the separation hopper 2 is separated into a sand and gravel filtration tank 5 and a fine sand sedimentation tank 6 by a partition plate 4. A communication tank 7 is provided at the lower part of the partition plate 4. The sand and gravel filtration tank 5 and the fine sand sedimentation tank 6 are communicated through the communication tank 7, and a filter screen is provided on the communication tank 7. An overflow port 8 is provided at the upper part of the fine sand sedimentation tank 6.

[0021] The external cleaning water of the concrete mixer truck and the cleaning water of the mixing tank are sent to the separation hopper 2 through a water channel or a drain pipe. The cleaning water first enters the sand and gravel filtration tank 5. Larger particles of sand and gravel in the cleaning water are blocked by the filter screen, so that the larger particles of sand and gravel are left in the sand and gravel filtration tank 5. There are gaps between the sand and gravel. The smaller fine sand follows the water flow through the gaps and the filter screen and flows into the fine sand sedimentation tank 6. When the water flow enters the fine sand sedimentation tank 6 through the connecting tank 7, the cross-sectional area of the pipeline increases, so that the water flow slows down. The fine sand in the cleaning water settles to the bottom of the fine sand sedimentation tank 6 under the action of gravity. Thus, the aggregates in the cleaning water of the concrete mixer truck are separated and left in the sand and gravel filtration tank 5 and the fine sand sedimentation tank 6, so as to recover the aggregates in the cleaning water, avoid pipeline blockage, and save aggregate resources at the same time. The cleaning water flows into the treatment tank body 1 through the overflow port 8 on the fine sand sedimentation tank 6. After the liquid level reaches a certain height, a flocculant is added to the treatment tank body 1 to quickly precipitate the suspended impurities in the cleaning water. Then, the upper clear liquid is pumped out by a water pump and stored in the clean water tank. At the same time, the sediment at the bottom of the treatment tank body 1 is regularly cleaned. This device can make the cleaning water recycled, reduce the consumption of water resources, and is convenient to use at construction sites where water intake is inconvenient.

[0022] The side of the separation hopper 2 is inclined, so that the sand and gravel filtration tank 5 has a structure with a larger upper part and a smaller lower part. When the cleaning water flows through the sand and gravel filtration tank 5, the flow rate will become faster at the bottom of the sand and gravel filtration tank 5, so as to wash the larger particles of sand and gravel, wash away the fine sand attached to the upper part of the larger particles of sand and gravel, and prevent the fine sand from accumulating in the sand and gravel filtration tank 5, so that all of it enters the fine sand sedimentation tank 6. The filter screen is mainly used to filter larger particles of sand and gravel, has a larger aperture, is not easy to be blocked, and is easy to clean. The fine sand is separated from the cleaning water by sedimentation, reducing the risk of blockage.

[0023] In a specific embodiment, as Figure 3 shown, drainage grooves 9 are provided on both sides of the fine sand sedimentation tank 6. A plurality of through holes are provided on the side of the drainage groove 9, and a geotextile layer 10 is provided on the inner wall of the drainage groove 9. The lower part of the drainage groove 9 is communicated with the treatment tank body 1. When the separated larger particles of sand and gravel and fine sand in the separation hopper 2 accumulate to a certain amount, they can be lifted by a crane or a chain block. After being lifted, the water in the separation hopper 2 is discharged from the separation hopper 2 through the drainage groove 9. The geotextile layer 10 can block the fine sand and only discharge the water. After the aggregates in the separation hopper 2 are cleaned, the separation hopper 2 is loaded into the treatment tank body 1. At this time, the bottom of the drainage groove 9 is attached to the bottom of the treatment tank body 1, and the pressure difference inside and outside the drainage groove 9 is balanced. The water in the fine sand sedimentation tank 6 will not flow through the drainage groove 9, so that the geotextile layer 10 is not easily blocked by the fine sand.

[0024] In a specific embodiment, as Figure 2As shown, the fine sand sedimentation tank 6 is provided with a guide plate 11 at the installation position of the filter screen. The guide plate 11 tilts upward by 20° to 40°, so that after the cleaning water enters the fine sand sedimentation tank 6, it flows upward through the guide plate 11, avoiding the water flow from scouring the fine sand at the bottom of the fine sand sedimentation tank 6, and enabling the sedimented fine sand to remain in the fine sand sedimentation tank 6.

[0025] In a preferred embodiment, the aperture of the filter screen is 5 mm to 10 mm. The filter screen is mainly used to filter larger particles of sand and gravel in the cleaning water. Therefore, the aperture is relatively large, making the filter screen not easily clogged and facilitating cleaning. Moreover, after the larger particles of sand and gravel accumulate at the bottom of the sand and gravel filtration tank 5, the gaps between the larger particles of sand and gravel can form an effect similar to a filter screen to filter the larger particles of sand and gravel in the cleaning water.

[0026] Specifically, as Figure 3 shown, sliding rods 12 are provided on both sides of the separation hopper 2. The two ends of the sliding rods 12 are fixedly connected to the separation hopper 2, and sleeves 13 are installed on the sliding rods 12. The sleeves 13 are connected to each other by a cross bar 14. A lifting ring 15 is provided on the cross bar 14. After connecting with the lifting ring 15 through a hoist or a crane on the gantry, the separation hopper 2 can be lifted. However, since the separation hopper 2 has an irregular structure and the proportion of sand and gravel in the muddy water is different, the weight proportion of the separated substances on the sand and gravel filtration tank 5 and the fine sand sedimentation tank 6 is also different. Therefore, by adjusting the position of the sleeve 13 on the sliding rod 12, it is possible to prevent the separation hopper 2 from tipping over after being lifted.

[0027] Specifically, a locking bolt 16 is provided on the sleeve 13. One end of the locking bolt 16 passes through the sleeve 13 and presses tightly on the sliding rod 12. After tightening the locking bolt 16, the sleeve 13 can be fixed on the sliding rod 12 to prevent the sleeve 13 from loosening during lifting.

[0028] Certainly, the present application can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by ordinary technicians in the art without any creative labor belong to the scope protected by the present application.
