Description

Technical Field

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

[0002] The concrete production process generates a large amount of wastewater containing cement particles, aggregate residues, and chemical additives. Direct discharge of this wastewater would cause serious environmental pollution and resource waste. With tightening environmental policies and increasing demands for green production, wastewater recycling and treatment have become a crucial aspect of the concrete industry's sustainable development. Current wastewater treatment equipment needs to integrate multi-stage processes such as solid-liquid separation, sedimentation, and deep filtration. Traditional equipment often suffers from low treatment efficiency and high maintenance costs due to structural design flaws. Therefore, there is an urgent need to develop a highly efficient, reliable, and easy-to-maintain concrete production wastewater recycling and treatment system to meet the demands of continuous production and environmental standards.

[0003] Existing concrete wastewater treatment equipment typically uses mechanical bar screens for initial solid-liquid separation. The working principle is to intercept larger solid particles through fixed bar screens, then use sedimentation tanks to separate suspended fine particles by gravity settling, and finally remove dissolved pollutants through filter media such as activated carbon or quartz sand. The bar screen part is mostly constructed by welding or bolting.

[0004] However, existing bar screens are prone to clogging of the screen gaps by fibrous or sticky debris during long-term operation, resulting in a reduction in water passage and a significant decrease in separation efficiency. Furthermore, the bar screens are mostly rigidly fixed, requiring machine shutdown and specialized tools for disassembly and cleaning, making the maintenance process cumbersome and time-consuming. This seriously affects the continuous operation capacity and production rhythm of the equipment, and fails to meet the dual requirements of high efficiency, stability and rapid maintenance of the wastewater treatment system for concrete production lines. Therefore, a concrete production wastewater recycling and treatment equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a concrete production wastewater recycling and treatment equipment, which aims to improve the problem that the existing technology mostly uses a rigid fixing method for the bar screen, which requires machine shutdown and special tools for disassembly and cleaning, making the maintenance process cumbersome and time-consuming, and seriously affecting the continuous operation capacity and production rhythm of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A concrete production wastewater recycling and treatment device includes a sedimentation frame, a separation frame fixedly connected to the top of the sedimentation frame, a grid frame slidably connected inside the separation frame, a handle fixedly connected to the top of the grid frame, a fixing hole provided on the side wall of the grid frame, and a hollow column fixedly connected inside the separation frame, with a positioning component provided inside the hollow column.

[0008] The positioning component includes a fixed column and a sliding column. The fixed column is slidably connected inside the hollow column. One end of the sliding column is fixedly connected to one end of the fixed column, and the other end of the fixed column engages with the fixing hole. An unlocking component is provided on the outer wall of the sliding column. A connecting pipe is fixedly connected to the side wall of the sedimentation frame. A filter frame is fixedly connected to one end of the connecting pipe. An adsorption plate is slidably connected inside the filter frame. A drain pipe is fixedly connected to the side wall of the filter frame. A disassembly component is provided inside the filter frame.

[0009] As a further description of the above technical solution:

[0010] The unlocking assembly includes a first disc and a third disc. The inner wall of the first disc is fixedly connected to the outer wall of the first sliding column. The inner wall of the third disc is fixedly connected to the outer wall of the first sliding column. A second disc is fixedly connected inside the hollow column. The first sliding column is rotatably connected inside the second disc. A locking pin is fixedly connected inside the first sliding column. The locking pin engages with the hollow column. A reset assembly is sleeved on the outer wall of the first sliding column.

[0011] As a further description of the above technical solution:

[0012] The reset assembly includes a spring, one end of which is fixedly connected to one side wall of the disk, and the other end of which is fixedly connected to the other side wall of the disk.

[0013] As a further description of the above technical solution:

[0014] The disassembly assembly includes a positioning post, which is slidably connected inside the filter frame. The side wall of the adsorption plate has a positioning hole, and the positioning post engages with the positioning hole.

[0015] As a further description of the above technical solution:

[0016] A hollow frame is fixedly connected to the outer wall of the filter frame, and a sliding post 2 is slidably connected inside the hollow frame. One end of the sliding post 2 is fixedly connected to the side wall of the positioning post.

[0017] As a further description of the above technical solution:

[0018] One end of the sliding post is rotatably connected to an unlocking handle, which is slidably connected to the outer wall of the hollow frame.

[0019] As a further description of the above technical solution:

[0020] A second spring is fitted on the outer wall of the sliding column 2. One end of the second spring is fixedly connected to the side wall of the positioning column, and the other end of the second spring is fixedly connected to the inner wall of the hollow frame.

[0021] As a further description of the above technical solution:

[0022] A pull rod is slidably connected inside the sedimentation frame, and a scraper is fixedly connected to one end of the pull rod. A drain frame is fixedly connected to the bottom of the sedimentation frame, and a sealing cover is slidably connected inside the drain frame.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the hollow column fixed inside the separation frame drives the fixed column in the positioning component to slide along the hollow column, so that the fixed column engages with the fixing hole on the side wall of the grid frame, realizing the stable positioning of the grid frame within the separation frame; subsequently, when it is necessary to clean the solid particles inside the grid frame, the sliding column of the unlocking component drives the locking column to disengage from the locking structure of the hollow column, and at the same time drives the fixed column to disengage from the fixing hole, thereby allowing the grid frame to be smoothly removed from the separation frame through the top handle, and the large particles of debris trapped inside can be cleaned, thus achieving the effect of convenient disassembly of the grid frame and efficient removal of trapped debris, solving the problem that traditional grid devices are prone to blockage by debris affecting separation efficiency and difficult disassembly and maintenance, improving the ease of maintenance of the equipment and the continuity of solid-liquid separation.

[0025] 2. In this utility model, a sliding rod inside the sedimentation frame drives a scraper to move within the sedimentation frame, scraping away the sediment accumulated at the bottom of the frame. The scraped sediment can be discharged through a drain frame and a sealing cover at the bottom of the sedimentation frame. Subsequently, wastewater is transported to the filter frame through a connecting pipe fixed to the side wall of the sedimentation frame. The adsorption plate inside the filter frame further filters and purifies the wastewater. When the adsorption plate is saturated, the unlocking handle of the disassembly component drives the sliding column two to slide within the hollow frame, thereby causing the positioning column to disengage from the positioning hole on the side wall of the adsorption plate. This allows the adsorption plate to be removed from the filter frame for replacement, achieving the dual functions of efficiently removing sediment and ensuring filtration effect. This solves the problems of sediment accumulation affecting sedimentation efficiency and the inconvenience of replacing saturated adsorption plates leading to a decrease in filtration effect, thus improving the wastewater treatment quality and operational stability of the equipment.

[0038] Reference Figure 1 - Figure 7The disassembly assembly includes a positioning post 24, which is used to engage with the positioning hole 22 of the adsorption plate 21 to achieve its installation and fixation. The positioning post 24 is slidably connected inside the filter frame 20. The side wall of the adsorption plate 21 has a positioning hole 22, which is used to receive the positioning post 24 to achieve precise positioning and fixation of the adsorption plate 21.

One end of the sliding post 25 is fixedly connected to the side wall of the positioning post 24, and the other end of the sliding post 25 extends to the operating area. One end of the sliding post 25 is rotatably connected to an unlocking handle 27, which is used to provide operating force.

[0039] Working principle: Concrete production wastewater first enters the grid frame 3 inside the separation frame 2 for preliminary filtration to intercept large particles of debris. The fixed column 6 inside the separation frame 2 drives the fixed column 7 in the positioning component to slide along the inner wall of the hollow column 6, so that one end of the fixed column 7 is engaged in the fixing hole 5 on the side wall of the grid frame 3, realizing the stable positioning of the grid frame 3 in the separation frame 2. When it is necessary to clean the debris inside the grid frame 3, the sliding column 8 of the unlocking component drives the fixed locking column 12 inside it to disengage from the locking structure of the hollow column 6. At the same time, the sliding column 8 drives the fixed fixed column 7 to disengage from the fixing hole 5. Then, the handle 4 fixed on the top of the grid frame 3 drives the grid frame 3 to slide along the inner wall of the separation frame 2 to be removed. After cleaning, the operation is reversed to make the fixed column 7 re-engage in the fixing hole 5 to complete the reset.

[0040] After preliminary filtration, the wastewater enters the sedimentation frame 1 and settles. After the sediment accumulates, the pull rod 16, which is slidably connected inside the sedimentation frame 1, drives the scraper 17, which is fixed at one end, to move horizontally within the sedimentation frame 1 to scrape off the sediment at the bottom of the sedimentation frame 1. Then, the sediment is discharged from the drain frame 14 by sliding the sealing cover 15 inside the drain frame 14, which is fixed at the bottom of the sedimentation frame 1. The settled wastewater is then transported to the filter frame 20 through the connecting pipe 19 fixed to the side wall of the sedimentation frame 1. The adsorption plate 21, which is slidably connected inside the filter frame 20, performs deep filtration and purification on the wastewater. The purified wastewater is discharged for reuse through the drain pipe 18 fixed to the side wall of the filter frame 20.

[0041] When the adsorption plate 21 is saturated, by rotating the unlocking handle 27 connected to one end of the sliding column 25, the sliding column 25 is driven to slide along the inner wall of the hollow frame 23 fixed on the outer wall of the filter frame 20. The sliding column 25 drives the positioning column 24 fixed at one end to disengage from the positioning hole 22 on the side wall of the adsorption plate 21, and then drives the adsorption plate 21 to slide along the inner wall of the filter frame 20 to be removed for replacement. After replacement, the unlocking handle 27 is pushed in the opposite direction, and the elastic force of the spring 26 drives the positioning column 24 to re-engage with the positioning hole 22, thereby realizing the fixed reset of the adsorption plate 21.
