Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete preparation technology, and in particular to an active treatment device for waste slurry used in the preparation of recycled concrete. Background Technology
[0002] Existing concrete preparation processes generate a large amount of waste slurry. Waste slurry treatment is time-consuming and labor-intensive, and failure to treat it will cause environmental pollution. Therefore, it is proposed to use waste slurry to replace mixing water in a certain proportion to prepare recycled concrete. By using waste slurry to replace mixing water, the solid particles in the waste slurry can effectively improve the density and anti-bleeding ability of concrete, and the addition of active minerals will also improve the strength of concrete.
[0003] Before replacing the mixing water with waste slurry, the waste slurry needs to be revitalized. Appropriate types and qualities of modifiers are added to the waste slurry to match its composition. At the same time, before use, the solid content of the modified waste slurry needs to be within a suitable range according to the concrete process.
[0004] Existing modification devices are typically small-scale stirring devices, which have the following problems during use:
[0005] 1. Due to the large demand for mixing water, the small processing capacity results in low production efficiency of recycled concrete.
[0006] 2. It is difficult to control the solid content, and stirring and filtration are carried out separately;
[0007] 3. Residual solid matter inside the device is difficult to clean and can easily affect the active treatment of waste slurries with different components. Utility Model Content
[0008] This utility model provides an active treatment device for waste slurry in the preparation of recycled concrete, which aims to solve the problems of low processing capacity, difficulty in controlling solid content, and difficulty in cleaning the active treatment device for waste slurry used to replace mixing water in the process of recycled concrete production.
[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0010] An active treatment device for waste slurry in the preparation of recycled concrete includes a tank, a plate frame inside the tank, and sliding mechanisms at both ends of the top of the plate frame. The two ends of the plate frame are slidably engaged with the top of the tank through the sliding mechanisms. The plate frame divides the tank into two independent compartments. A filter plate is detachably installed inside the plate frame. The two independent compartments are interconnected through the filter plate. A blade is provided around one side of the filter plate, and the blade forms a scraper that is tangent to the inner wall of the tank.
[0011] Preferably, the blade is U-shaped and coaxial with the plate frame.
[0012] More preferably, the cross-section of the cutting edge is a right-angled triangle, with one right-angled side of the cutting edge forming a fixed fit with the outer side of the plate frame, and the other right-angled side of the cutting edge adhering to the inner wall of the groove.
[0013] Furthermore, the plate frame includes a T-shaped frame, which is arranged vertically. The top two ends of the T-shaped frame are slidably engaged with the top of the groove through a sliding mechanism, and the sidewalls of the T-shaped frame are tightly attached to the inner wall of the groove.
[0014] Furthermore, the T-shaped frame is provided with a mounting groove with a top opening, the mounting groove is parallel to the T-shaped frame, and the top opening of the mounting groove is located at the top middle position of the T-shaped frame. The filter plate is detachably embedded in the mounting groove.
[0015] Specifically, the T-shaped frame has a filter hole in the middle, which is perpendicular to and passes through the T-shaped frame, and the filter plate protrudes from the filter hole.
[0016] More specifically, a handle is provided at the top center of the filter plate.
[0017] In detail, the filter plate and the filter holes are arranged concentrically and coaxially, and the length of the filter holes is less than the length of the mounting groove, and the height of the filter holes is less than the height of the mounting groove.
[0018] More specifically, the sliding mechanism includes sliding grooves on both sides of the top of the groove body, and a traveling wheel is rotatably installed at both ends of the top of the T-shaped frame of the plate frame. The traveling wheel is embedded in the corresponding sliding groove. A motor is provided on both sides of the top of the T-shaped frame. The motor outputs synchronously at the same speed, and the output shaft of the motor is linked with the traveling wheel on the corresponding side.
[0019] The beneficial effects of this utility model are:
[0020] 1. This utility model uses a tank and a movable filter plate, which allows mixing and filtration to be carried out at the same time. Mixing is done first, followed by filtration, which increases the processing capacity and ensures the subsequent use of recycled concrete.
[0021] 2. This utility model, by changing the size of the filter plate, facilitates the control of the solid content, so that the filtered liquid meets production requirements.
[0022] 3. This utility model uses a blade belt to clean the inner wall of the tank, while concentrating solid waste to one side for easy cleaning. Attached Figure Description

[0031] The embodiments will be further described below with reference to the accompanying drawings.
[0032] like Figures 1-4 As shown in the preferred embodiment 1, the waste slurry activation treatment device for recycled concrete preparation includes a tank 1. A plate frame 2 is provided inside the tank 1. Sliding mechanisms 3 are provided at both ends of the top of the plate frame 2, and the two ends of the plate frame 2 are slidably engaged with the top of the tank 1 through the sliding mechanisms 3. The plate frame 2 divides the tank 1 into two independent tanks. A filter plate 4 is detachably provided inside the plate frame 2. The two independent tanks are interconnected through the filter plate 4. A blade 6 is provided around one side of the filter plate 4, and the blade 6 forms a scraper that is tangent to the inner wall of the tank 1.
[0033] During the active treatment, the plate frame 2 is moved by the sliding mechanism 3 so that the blade 6 is away from the inner wall of the opposite tank 1. Concrete waste slurry and the corresponding modifier are added. After stirring by adding an external mixing mechanism, the mixture is left to stand for active modification.
[0034] After the active modification treatment is completed, the plate frame 2 is moved by the sliding mechanism 3, so that the blade 6 is close to the inner wall of the opposite tank 1. During the process, the waste slurry liquid after active modification enters the independent tank where the blade 6 is located through the filter plate 4 and enters the independent tank where the blade 6 is not. The waste slurry and the solid sediment generated during the modification process are intercepted by the filter plate 4 and continuously collected during the movement of the plate frame 2. The residue on the inner wall is also scraped off by the blade 6 and collected into the independent tank where the blade 6 is located, which is convenient for cleaning and collection. When needed, the liquid in the independent tank where the blade 6 is not located can be directly pumped into the recycled concrete preparation system to replace part of the mixing water with waste slurry and improve the quality of concrete.
[0035] Meanwhile, the sieve plate 4 is easy to replace. By controlling the aperture of the sieve plate 4, the solid content in the modified waste slurry after filtration can be controlled to ensure the technical requirements when replacing the mixing water are met.
[0036] In a preferred embodiment 2, the blade 6 is U-shaped and coaxial with the plate frame 2.
[0037] The cross-section of the blade 6 is a right-angled triangle. One right-angled side of the blade 6 forms a fixed fit with the outer side of the plate frame 2, and the other right-angled side of the blade 6 is in contact with the inner wall of the groove 1. This ensures the formation of a scraper structure to scrape the inner wall of the groove 1, while simultaneously concentrating the scraped material towards the center of the plate frame 2.
[0038] As a preferred embodiment 3, the plate frame 2 includes a T-shaped frame 21, which is arranged vertically. The top two ends of the T-shaped frame 21 are slidably engaged with the top of the tank 1 through a sliding mechanism 3. The side wall of the T-shaped frame 21 is tightly attached to the inner wall of the tank 1. The T-shaped frame 21 and the tank 1 form a limiting sliding to ensure the filtration effect and reduce the amount of solids entering the filtered liquid.
[0039] The T-shaped frame 21 has a top-opening mounting groove 23, which is parallel to the T-shaped frame 21. The top opening of the mounting groove 23 is located at the top center of the T-shaped frame 21. The filter plate 4 is detachably embedded in the mounting groove 23, facilitating the installation and removal of the filter plate 4 for replacement according to actual requirements.
[0040] The T-shaped frame 21 has a filter hole 22 in the middle, which is perpendicular to and passes through the T-shaped frame 21, and the filter plate 4 protrudes from the filter hole 22. This ensures the filtration effect and efficiency.
[0041] A handle 5 is provided at the top center of the filter plate 4 for easy replacement of the filter plate 4.
[0042] The filter plate 4 and the filter holes 22 are arranged concentrically and coaxially, with the length of the filter holes 22 being less than the length of the mounting groove 23 and the height of the filter holes 22 being less than the height of the mounting groove 23. This ensures the filtration effect and prevents interference between installation and filtration.
[0043] In a preferred embodiment 4, the sliding mechanism 3 includes sliding grooves 31 located on both sides of the top of the groove 1. Both ends of the top of the T-shaped frame 21 of the plate frame 2 are rotatably mounted with traveling wheels 33, which are embedded in the corresponding sliding grooves 31. Motors 32 are located on both sides of the top of the T-shaped frame 21, and the motors 32 output synchronously at the same speed. The output shafts of the motors 32 are linked with the traveling wheels 33 on the corresponding sides, causing the traveling wheels 33 to move synchronously, thus moving the T-shaped frame 21.
[0044] Preferably, the motor 32 is installed vertically and the traveling wheel 33 is installed horizontally, with the output shaft of the motor 32 and the rotating shaft of the traveling wheel 33 forming a linkage through a bevel gear.
[0045] As a preferred embodiment 5, the bottom sides of the T-shaped frame 21 form a limiting sliding fit with the bottom of the inner wall of the groove 1 through the slide rail, which further ensures the stability of the sliding.
[0046] The working principle of this utility model:
[0047] During the active treatment, the plate frame 2 is moved by the sliding mechanism 3 so that the blade 6 is away from the inner wall of the opposite tank 1. Concrete waste slurry and the corresponding modifier are added. After stirring by adding an external mixing mechanism, the mixture is left to stand for active modification.
[0048] After the active modification treatment is completed, the plate frame 2 is moved by the sliding mechanism 3, so that the blade 6 is close to the inner wall of the opposite tank 1. During the process, the waste slurry liquid after active modification enters the independent tank where the blade 6 is located through the filter plate 4 and enters the independent tank where the blade 6 is not. The waste slurry and the solid sediment generated during the modification process are intercepted by the filter plate 4 and continuously collected during the movement of the plate frame 2. The residue on the inner wall is also scraped off by the blade 6 and collected into the independent tank where the blade 6 is located, which is convenient for cleaning and collection. When needed, the liquid in the independent tank where the blade 6 is not located can be directly pumped into the recycled concrete preparation system to replace part of the mixing water with waste slurry and improve the quality of concrete.
[0049] Meanwhile, the sieve plate 4 is easy to replace. By controlling the aperture of the sieve plate 4, the solid content in the modified waste slurry after filtration can be controlled to ensure the technical requirements when replacing the mixing water are met.
