Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for recycling water used for cleaning cement mixer trucks. Background Technology

[0002] As we all know, with the rapid development of infrastructure construction in my country, cement mixer trucks, as key equipment in concrete transportation and construction, are being used more and more frequently. In daily operations, cement mixer trucks need to be cleaned after each concrete transportation task to prevent residual concrete from solidifying in the tank and affecting the next use.

[0003] The cleaning process generates a large amount of wastewater containing cement particles, sand, plastic bags and other impurities. Traditional cleaning methods usually discharge this wastewater directly to the ground or drainage system, which not only wastes a lot of water resources, but also pollutes the surrounding environment and increases the burden of wastewater treatment. In addition, if a filtration device is installed, its portability for maintenance must also be considered. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4A water recycling device for cleaning cement mixer trucks includes a filter box 1, a water storage tank 2, a water inlet frame 3, a grid 4, a secondary filter layer 5, a tertiary filter layer 6, a lifting device, and a moving device. The water storage tank 2 is installed on the bottom wall of the filter box 1. A conveying pipe 7 is installed on the side wall of the filter box 1, and the other end of the conveying pipe 7 is connected to the top wall of the water storage tank 2. The water inlet frame 3 is installed on the top wall of the filter box 1. The grid 4 is slidably installed inside the water inlet frame 3. Fixed plates 8 are installed at the four corners of the top wall of the grid 4. Adjustable frames 9 with side openings are installed on the left and right side walls of the water inlet frame 3. The adjustable frames 9 are connected to the top walls of the four sets of fixed plates 8 through the lifting device. The filter box 1 is equipped with a secondary filter layer 5 and a tertiary filter layer 6 installed from top to bottom. An L-shaped outlet pipe 10 is installed on the top wall of the water storage tank 2 near the end of the conveying pipe 7. A pump body 11 is installed on the outer wall of the L-shaped outlet pipe 10. A controller 12 is installed on the outer wall of the filter box 1. The moving device is installed at the four corners of the bottom of the water storage tank 2. In this embodiment, during use, the device is moved to the outlet of the cement mixer truck using the moving device to guide the wastewater generated from cleaning the cement mixer truck into the inlet frame 3. The wastewater first passes through a screen 4 for filtration. The screen 4 is slidably installed inside the inlet frame 3 to intercept larger impurities such as stones, plastic bags, and other large particles. To facilitate cleaning of the screen 4... The adjusting frame 9 and the lifting device work together to remove debris. The controller 12 controls the lifting device to move the fixed plate 8 up and down, thereby raising the screen 4 from the inlet frame 3, making it easier for operators to clean up debris. After passing through the screen 4, the sewage enters the filter box 1 and passes through the secondary filter layer 5 and the tertiary filter layer 6 for further filtration. The secondary filter layer 5 can effectively remove larger suspended particles in the water, and the tertiary filter layer 6 is used to further remove fine particles and some organic matter, improving water cleanliness. The tertiary filter layer 6 can be selected for installation and use according to actual needs. If the water quality requirements are not high, it can be omitted. The clean water after multi-stage filtration flows through the delivery pipe 7 into the bottom water storage tank 2 for storage. When the cleaning water needs to be reused, the pump body 11 on the outer wall of the L-shaped outlet pipe 10 is started to pressurize and transport the water in the water storage tank 2 to the cleaning point, realizing the recycling of water resources. The operation of the entire system can be automatically managed by the controller 12, which improves the convenience and efficiency of operation. The screen 4 adopts a sliding installation method and is equipped with a lifting device, which makes it easy to remove and clean quickly, preventing blockage from affecting the filtration efficiency. By recycling and filtering the cleaning water, the consumption of fresh water sources is greatly reduced, and the amount of wastewater discharged during construction is reduced, which meets the requirements of green construction and sustainable development. A mobile device is provided below the water storage tank 2, which gives the entire device good mobility and is suitable for flexible arrangement in different sites.

[0025] Preferably, in this embodiment, the lifting device includes a drive motor 13, a threaded rod 14, a slider 15, a connecting column 16, and a horizontal plate 17. The threaded rod 14 is rotatably installed inside two sets of adjusting frames 9. The drive motor 13 is installed through the bottom wall of each set of threaded rods 14, and the slider 15 is threaded onto the outer wall of the threaded rod 14. The connecting column 16 is installed on the side walls of both sets of sliders 15. A horizontal plate 17 is installed at the end of each set of connecting columns 16 away from the slider 15. The two ends of the bottom wall of each set of horizontal plates 17 are fixedly connected to the top walls of the corresponding two sets of fixing plates 8. In the initial state, the grille 4 is located inside the water inlet frame 3 to intercept large particles of impurities in the wastewater generated by the cement mixer truck. At this time, the slider 15 is located at a certain position of the threaded rod 14 (usually near the bottom), so that the grille 4 is in the working position, i.e., submerged in the wastewater for preliminary filtration. After the water is filtered, the large particles on the grille 4 need to be further filtered. During cleaning, the drive motor 13 is started by the controller 12. The drive motor 13 is installed on the bottom wall of the adjustment frame 9 and connected to the threaded rod 14. The two sets of drive motors 13 start to rotate at the same time, driving the two sets of threaded rods 14 to rotate synchronously. Since the slider 15 is installed on the threaded rod 14 through threaded engagement, when the threaded rod 14 rotates, the slider 15 will move up or down along the threaded rod 14. During this process, the direction of movement of the slider 15 depends on the rotation direction of the drive motor 13. In order to lift the grid 4, the drive motor 13 will cause the threaded rod 14 to rotate counterclockwise, thereby causing the slider 15 to move up along the threaded rod 14. As the slider 15 rises, the connecting column 16 and the horizontal plate 17 also rise. The bottom walls of each set of horizontal plates 17 are fixedly connected to the top walls of the corresponding two sets of fixed plates 8, which means that the fixed plates 8 will also rise with the horizontal plates 17. When the horizontal plates 17 rise, the grid 4 will also be lifted together and gradually leave the water inlet frame 3 until it is fully raised to a height that is convenient for the operator to clean.

[0026] Preferably, in this embodiment, the drive motor 13 is a servo motor. The servo motor allows for precise adjustment of the rotation speed, which can ensure that the threaded rods 14 on both sides rotate at completely consistent speeds and angles, thereby driving the slider 15, connecting column 16 and horizontal plate 17 to rise or fall synchronously. This allows the rising or falling speed of the grille 4 to be dynamically adjusted according to specific application requirements, ensuring both operational efficiency and equipment safety.

[0027] Preferably, in this embodiment, the secondary filtration layer 5 is a quartz sand filtration layer. Quartz sand is a common filter material with good physical stability. Its particle structure can effectively trap suspended particulate matter in the water, including cement particles, fine sand and gravel, and other impurities, thereby purifying the water quality. Quartz sand has high hardness and wear resistance, and is not easily worn or broken under normal use conditions, resulting in a long service life and further reducing the cost of replacing filter materials.

[0028] Preferably, in this embodiment, the third-stage filtration layer 6 is an activated carbon adsorption layer. Activated carbon has a highly developed pore structure and a huge specific surface area, which enables it to effectively adsorb organic compounds, trace pollutants and odor substances in water. When the water treated by activated carbon adsorption is used to clean the cement mixer truck again, the residual organic matter and odor in the water are reduced.

[0029] Preferably, in this embodiment, the moving device includes casters 18 and a brake assembly 19. The casters 18 are installed at the four corners of the bottom of the water tank 2, and the brake assembly 19 is installed on the casters 18. The brake assembly 19 is adapted to the casters 18. The casters 18 allow the water tank 2 to move in any direction, which greatly improves the convenience of transferring the equipment between different construction sites. It can be easily pushed on both flat ground and slightly uneven surfaces. When it reaches the designated position, the operator can immediately lock the casters 18 with the brake assembly 19 to prevent the equipment from sliding due to accidental collisions or other external forces, thus ensuring safety during use.

[0030] Preferably, in this embodiment, a liquid level sensor 20 is installed in the water storage tank 2. The liquid level sensor 20 can monitor the water level in the water storage tank 2 in real time and provide accurate water level information.

[0031] Preferably, in this embodiment, a protective shell 21 is installed on the top of the controller 12. The protective shell 21 can protect the top of the controller 12 and prevent foreign objects from hitting the controller 12 and causing unnecessary damage.

[0032] To illustrate the possible application scenarios, technical principles, implementable specific solutions, and achievable objectives and effects of this application in detail, the following description, in conjunction with the listed specific embodiments and accompanying drawings, provides a detailed explanation. The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.
