Description

Technical Field

[0001] This utility model relates to the field of construction waste recycling and treatment technology, specifically to a waste concrete separation device. Background Technology

[0002] Waste concrete typically refers to discarded or surplus concrete material generated during construction projects. This concrete may be discarded due to excess, damage, non-compliance with specifications, or other reasons during construction. This waste concrete may include hardened concrete blocks, fragments, or other forms of waste concrete.

[0003] An existing patent (publication number: CN222754015U) discloses a waste concrete separation device. This patent facilitates the separation of waste concrete while also allowing for further flushing and separation. However, during the development of this utility model, the following problems were discovered with the existing technology:

[0004] Firstly, fixed screens are prone to adhesion and failure. When relying on fixed screens to screen concrete blocks, concrete debris easily sticks to the screen holes, causing the screening efficiency to decrease rapidly over time.

[0005] Secondly, the mud and water cleaning ability is lacking: the separation box is not equipped with a specific flushing structure, and mud and water are easy to accumulate in the corners of the box or under the screen, which increases the risk of equipment blockage.

[0006] Third, the steel bar separation is ineffective: no stripping mechanism was designed for the steel bars in the waste concrete, and the steel bars will enter the subsequent process along with the concrete blocks, affecting the quality of stone recycling. Therefore, there is an urgent need for a waste concrete separation device to solve the above problems. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides a waste concrete separation device that has the advantages of efficient steel bar separation, smooth stone screening, and convenient cleaning, solving the problems of incomplete steel bar separation, easy clogging of stone screening, and mud and water residue caused by the lack of a cleaning system.

[0009] (II) Technical Solution

[0010] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a waste concrete separation device, including a device shell, a steel bar separation mechanism is provided on the top of the device shell, and a stone separation mechanism is provided inside the device shell;

[0011] The rebar separation mechanism includes a sorting box fixedly connected to the top of the equipment housing. A first motor is fixedly installed on the side wall of the sorting box. A magnetic roller is fixedly connected to one end of the first motor that extends into the interior of the sorting box. A rebar separation port is opened on the side wall of the sorting box near the magnetic roller. A scraper that is in contact with the surface of the magnetic roller is fixedly connected inside the rebar separation port. A rebar screen is inclinedly arranged on the inner wall of the sorting box.

[0012] The stone separation mechanism includes a screening roller rotatably connected to the inside of the equipment housing via bearings. Screening plates are fixedly connected to the outside of the screening roller. A drive mechanism for driving the screening roller to rotate is provided on the outer wall of the equipment housing. A cleaning mechanism is provided inside the equipment housing for cleaning the stone and the inner cavity of the equipment housing.

[0013] The beneficial effects of this utility model are:

[0014] This waste concrete separation equipment uses a rotating magnetic roller to attract and adsorb steel bars in the mixture. A scraper attached to the surface peels the steel bars off the magnetic roller in real time. When the screening roller rotates synchronously, the screening plate continuously scrapes the screening surface, effectively removing the screen holes where concrete debris is stuck. Multiple rollers work together to disperse the material pressure and avoid local accumulation. The bottom sprayer matches the inclined shell bottom, and the spray direction is consistent with the angle of the bottom wall, which specifically washes the muddy and watery areas below the screening roller and at the bottom of the shell.

[0015] Based on the above technical solution, the present invention can be further improved as follows.

[0016] Furthermore, the cleaning mechanism includes a first sprayer fixedly installed on the top wall of the equipment housing, the bottom wall of the equipment housing is inclined, and a second sprayer is fixedly installed on the bottom wall of the equipment housing.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the first sprayer at the top pre-cleans the falling stones, removing most of the mud and water from the surface; the second sprayer with the inclined inner bottom wall sprays in the same direction as the inclined angle of the shell bottom, specifically flushing the mud and water area below the screening roller and the shell bottom, covering no dead corners and improving the cleaning efficiency.

[0018] Furthermore, a water tank is fixedly installed on the top of the equipment housing, and a water pump is fixedly installed on the side wall of the water tank. The outlet of the water pump is fixedly connected to a first delivery pipe and a second delivery pipe through a three-way pipe. The other end of the first delivery pipe is fixedly connected to a first sprayer, and the other end of the second delivery pipe is fixedly connected to a second sprayer. Solenoid valves are installed inside both the first delivery pipe and the second delivery pipe.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the water tank and water pump realize water supply, and the solenoid valve independently controls the spray intensity.

[0020] Furthermore, a steel bar discharge plate is provided at the steel bar separation port, and a feed funnel is fixedly connected to the top of the sorting box.

[0021] The beneficial effects of adopting the above-mentioned further scheme are that the feed funnel guides the material to enter evenly and avoids accumulation; the inclined steel bar discharge plate discharges the steel bars in an orderly manner, preventing jamming and ensuring continuous separation.

[0022] Furthermore, a stone discharge plate is provided on the side wall of the equipment housing, and a mud and water discharge port is provided at the bottom of the equipment housing.

[0023] The advantages of adopting the above-mentioned further solutions are that the inclined discharge plate facilitates the rapid discharge of stone materials and avoids accumulation; the bottom mud and water inlet collects the materials centrally, achieving convenient solid-liquid separation and reducing manual cleaning.

[0024] Furthermore, the drive mechanism includes a second motor fixedly installed on the front of the equipment housing, a transmission shaft fixedly connected to the output shaft of the second motor, the transmission shaft being fixedly connected to the screening roller, and the number of transmission shafts being several, with two adjacent transmission shafts being connected by a belt drive assembly.

[0025] The advantages of adopting the above-mentioned further solution are that a single motor drives multiple rollers to rotate synchronously via a belt, reducing energy consumption; uniform screening avoids excessive local pressure, prevents clogging, and improves stability.

[0031] 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.

[0032] In the embodiments, by Figure 1-4 A waste concrete separation device is provided, comprising a housing 1, a rebar separation mechanism on the top of the housing 1, a sorting box 2 fixedly connected to the top of the housing 1, a first motor 3 fixedly installed on the side wall of the sorting box 2, a magnetic roller 4 fixedly connected to one end of the first motor 3 extending into the interior of the sorting box 2, a rebar separation port 5 opened on the side wall of the sorting box 2 near the magnetic roller 4, a scraper 6 fixedly connected inside the rebar separation port 5 and in contact with the surface of the magnetic roller 4, a rebar screen 7 inclinedly arranged on the inner wall of the sorting box 2, a rebar discharge plate 12 provided at the rebar separation port 5, and a feed funnel 13 fixedly connected to the top of the sorting box 2.

[0033] In this embodiment, in actual use, the feeding funnel 13 guides the material to enter evenly to avoid accumulation. The inclined steel bar screen 7 guides the steel bars to the magnetic suction roller 4 at a lower position. The steel bars are attracted to the outside of the magnetic suction roller 4. The magnetic suction roller 4 is driven to rotate by the first motor 3. The scraper 6 scrapes off the steel bars outside the magnetic suction roller 4. The steel bars are discharged in an orderly manner by the inclined steel bar discharge plate 12 to prevent jamming and ensure continuous separation.

[0034] Specifically, refer to Figure 2 The equipment housing 1 is equipped with a stone separation mechanism, which includes a screening roller 8 rotatably connected to the inside of the equipment housing 1 via a bearing. Screening plates 9 are fixedly connected to the outside of the screening roller 8. A drive mechanism for driving the screening roller 8 to rotate is provided on the outer side wall of the equipment housing 1. A stone discharge plate 18 is provided on the side wall of the equipment housing 1. A mud and water discharge port 19 is opened at the bottom of the equipment housing 1.

[0035] In this embodiment, in actual use, the inclined stone discharge plate 18 facilitates the rapid discharge of stone, avoids accumulation, and the bottom mud and water inlet collects the stone, achieving convenient solid-liquid separation and reducing manual cleaning.

[0036] Specifically, refer to Figure 3 The drive mechanism includes a second motor 21 fixedly installed on the front of the equipment housing 1. A transmission shaft 20 is fixedly connected to the output shaft of the second motor 21. The transmission shaft 20 is fixedly connected to the screening roller 8. There are several transmission shafts 20. Two adjacent transmission shafts 20 are connected by a belt drive assembly 22.

[0037] In this embodiment, in actual use, the belt drive assembly 22 includes a pulley disposed outside the drive shaft 20. The two drive shafts 20 are connected to the belt drive through the pulley. A single motor drives multiple rollers to rotate synchronously through the belt. The screening roller 8 drives the screening plate 9 to rotate, thereby causing the screening plate 9 to scrape off the mud and sand on the outside of the stone. The cleaning effect is excellent. The uniform rotation driving force can avoid local accumulation of stone, prevent blockage of the screening channel, and improve the stability of stone screening.

[0038] Specifically, refer to Figure 2 The equipment housing 1 is equipped with a cleaning mechanism for cleaning the stone and the inner cavity of the equipment housing 1. The cleaning mechanism includes a first sprayer 10 fixedly installed on the inner top wall of the equipment housing 1. The inner bottom wall of the equipment housing 1 is inclined. A second sprayer 11 is fixedly installed on the inner bottom wall of the equipment housing 1.

[0039] In this embodiment, in actual use, the top first sprayer 10 pre-cleans the falling stones, removing most of the mud and water from the surface. The second sprayer 11, with its inclined inner bottom wall, sprays in the same direction as the inclined angle of the shell bottom, specifically flushing the mud and water area below the screening roller 8 and the bottom of the shell, covering no dead corners and improving cleaning efficiency.

[0040] Specifically, refer to Figure 2 A water tank 14 is fixedly installed on the top of the equipment housing 1. A water pump 15 is fixedly installed on the side wall of the water tank 14. The outlet of the water pump 15 is fixedly connected to a first delivery pipe 16 and a second delivery pipe 17 through a three-way pipe. The other end of the first delivery pipe 16 is fixedly connected to the first sprayer 10, and the other end of the second delivery pipe 17 is fixedly connected to the second sprayer 11. Solenoid valves are installed inside both the first delivery pipe 16 and the second delivery pipe 17.

[0041] Water tank 14 and water pump 15 provide water supply. The solenoid valve can independently control the opening and closing of the two sprayers and the spray intensity. A filter recycling pipeline can be added to connect to the mud and water discharge port to filter the mud and water and return it to the water tank, thus realizing water resource recycling.

[0042] Working principle:

[0043] Waste concrete mixture is generally crushed by a crusher and then falls into the sorting box 2 through the feed hopper 13. The first motor 3 drives the magnetic roller 4 to rotate, and the magnetic roller 4 adsorbs the steel bars in the mixture. The inclined steel bar screen 7 guides the fine steel bars to the bottom of the magnetic roller 4, and the scraper 6 scrapes off the steel bars on the surface of the magnetic roller 4. The steel bars are discharged along the steel bar discharge plate 12, realizing the separation of steel bars from concrete blocks.

[0044] After the concrete blocks are separated from the reinforcing bars, they fall to the stone separation mechanism. The second motor 21 drives multiple screening rollers 8 to rotate synchronously via belt drive, and the screening plates 9 scrape the mud and sand on the surface of the stone. At the same time, the water in the water tank 14 is pumped out by the water pump 15 and enters the first sprayer 10 through the first conveying pipe 16 to pre-clean the falling stone and remove the surface mud and water. The clean stone is discharged along the inclined stone discharge plate 18. The separated mud and water fall into the bottom of the equipment shell 1, and the second sprayer 11 washes the mud and water remaining at the bottom of the shell. Finally, the mud and water are discharged through the mud and water discharge port 19, completing the entire waste concrete separation process.
