Description

Technical Field

[0001] The utility model relates to the technical field of concrete production and processing, in particular to a waste concrete separation device for concrete processing. Background Technique

[0002] Concrete is an engineering composite material in which aggregate is cemented into a whole by a cementing material. Generally speaking, concrete refers to cement concrete obtained by using cement as the cementing material, sand and stone as the aggregate, and mixing with water in a certain proportion and stirring. During the production and processing of concrete, due to reasons such as incorrect proportioning, equipment failure, and overproduction, waste concrete will be generated. Since waste concrete usually contains components such as sand, stone, and cement, it may also be mixed with impurities such as steel bars, wooden blocks, and plastics. To ensure environmental protection and subsequent utilization requirements, a separation device is needed to separate waste concrete.

[0003] Common waste concrete separation devices for concrete processing usually consist of an installation frame, a separation box, a feeding hopper, a screening component, a buffer component, etc. The separation box is installed on the installation frame, and the feeding hopper is arranged at the top of the separation box to add waste concrete into the separation box. The waste concrete is separated by the screening component, and the buffer component is used to buffer and unload the falling materials.

[0004] In traditional waste concrete separation devices for concrete processing, after waste concrete falls to the top of the screening component, the aggregate falls through the screening component, while impurities such as steel bars, wooden blocks, and plastics are intercepted at the top of the screening component. However, only relying on gravity to allow the cement and aggregate to naturally pass through the screening component can separate the cement and sand and gravel in the concrete, but the separation speed and effect are slow. To solve the above problems, some waste concrete separation devices for concrete processing add springs around the screening component and a cam and a motor at the bottom of the screening component. The motor drives the cam to squeeze the corresponding springs by the screening component, and the screening component vibrates under the action of the spring reset, thereby improving the separation speed and effect of the screening component. However, this method will accelerate the wear of the screening component due to the vibration method, shorten the service life of the screening component, and thus affect the separation efficiency and effect. For this reason, a waste concrete separation device for concrete processing is proposed. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides a waste concrete separation device for concrete processing to solve the above technical problems that the vibration method will accelerate the wear of the screening component, shorten the service life of the screening component, and thus affect the separation efficiency and effect.

[0007] (2) Technical solution

[0008] To achieve the above object, the utility model provides the following technical solution: A waste concrete separation device for concrete processing, comprising:

[0009] A device housing, and a connection cover plate provided at the top of the device housing, and a feed hopper is connected to the top of the connection cover plate in a communicating manner. A diversion seat is additionally provided at the bottom of the inner cavity of the device housing;

[0010] A separation screen plate is arranged at the upper, central and lower parts of the inner cavity of the device housing. The center of the top of the separation screen plate is rotatably connected to a rotating shaft, and stirring rods are evenly arranged on the surface of the rotating shaft;

[0011] A connecting shaft is arranged between adjacent separation screen plates and is connected to the rotating shaft. A driving motor is installed at the center of the bottom of the device housing and is coaxially connected to the connecting shaft. After waste concrete is conveyed into the device housing through the feed hopper, the waste concrete drops onto the top of the separation screen plate. The driving motor drives the stirring rods to rotate on the top of the separation screen plate through the connecting shaft and the rotating shaft, and stirs the waste concrete, so that the aggregate drops onto the diversion seat through the separation screen plate and rolls along the diversion seat to the outside of the device housing. On the one hand, by stirring the impurities with the stirring rods, it not only avoids the phenomenon that the impurities accumulate on the top of the separation screen plate and do not move to form a blockage, but also avoids the separation screen plate from vibrating, which may lead to accelerated wear of the screening assembly and affect the separation efficiency and effect; on the other hand, the stirring rods are integrally designed in an arc shape. When driving the impurities to rotate on the top of the separation screen plate, the impurities can be moved to the periphery of the top of the separation screen plate under the action of centrifugal force and fit with the inner wall of the device housing, so as to pre-treat the impurities and avoid the phenomenon that the impurities affect the separation speed and effect.

[0012] Preferably, discharge grooves are formed at the corresponding positions of the outer side of the device housing and the periphery of the top of the separation screen plate, and side blocking plates are additionally arranged in the inner cavities of the discharge grooves. The side blocking plates can be separated from the device housing, and the impurities concentrated on the periphery of the top of the separation screen plate can be removed to the outside of the device housing through the discharge grooves. It not only improves the separation efficiency of the separation screen plate and extends its service life, but also improves the working environment and product quality, and at the same time reduces the maintenance cost.

[0013] Preferably, receiving plates are installed around the lower part of the outer side of the device housing, and the position relationship between the receiving plates and the side blocking plates corresponds. After the impurities are removed to the outside, the receiving plates can collect some of the dropped impurities, avoiding the phenomenon that the impurities drop to the ground and splash around, making it difficult to find.

[0014] Preferably, a positioning groove is provided at the center of the bottom of the rotating shaft, and a positioning head is installed at the center of the top of the connecting shaft and corresponds to the positioning groove. When the rotating shaft is connected to the connecting shaft, the positioning head is inserted into the inside of the positioning groove, which facilitates the separation between the rotating shaft and the connecting shaft when the separation net plate is removed and replaced.

[0015] Preferably, a convex plate is added to the center of the upper part of the outer side of the side resistance plate, and the convex plate is rotatably connected to the equipment housing. The convex plate is designed with a lighter upper part and a heavier lower part, and a handle is installed on the outer side of the side resistance plate. The convex plate can fix the side resistance plate on the equipment housing, preventing the side resistance plate from separating from the equipment housing due to the impact of waste concrete and causing the leakage of waste concrete.

[0016] Preferably, guide columns are installed on both sides of the side resistance plate and connected to the equipment housing. The inner end of the back of the guide column is sleeved with a sliding block and connected to the side resistance plate. A limiting plate is installed at the outer end of the guide column, and a compression spring is sleeved on the surface of the guide column and fits between the sliding block and the limiting plate respectively. The convex plate can be rotated upward, and the side resistance plate can be driven to move through the handle, so that the sliding block moves in the same direction along the surface of the guide column and compresses the compression spring. This not only facilitates the separation operation of the side resistance plate from the equipment housing, but also facilitates the automatic reset operation of the side resistance plate under the action of the compression spring after the impurities are removed.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present utility model provides a waste concrete separation device for concrete processing, which has the following beneficial effects:

[0019] After the waste concrete is conveyed into the equipment housing through the feeding funnel in this waste concrete separation device for concrete processing, the waste concrete falls to the top of the separation net plate. The driving motor drives the stirring rod to rotate on the top of the separation net plate through the connecting shaft and the rotating shaft and stirs the waste concrete. The stirring rod is integrally arc-shaped. When driving the impurities to rotate on the top of the separation net plate, the impurities can be moved to the periphery of the top of the separation net plate under the action of centrifugal force and fit with the inner wall of the equipment housing, so as to pre-treat the impurities and prevent the phenomenon that the impurities affect the separation speed and effect. The aggregate falls onto the diversion seat through the separation net plate and rolls to the outside of the equipment housing along the diversion seat. By stirring the impurities with the stirring rod, not only the accumulation of impurities on the top of the separation net plate and blockage are avoided, but also the problem of accelerated wear of the screening assembly caused by the vibration of the separation net plate is avoided, thereby improving the service life of the screening assembly, that is, avoiding the phenomenon that affects the separation efficiency and effect.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 making creative efforts belong to the protection scope of the present utility model.

[0027] The present utility model provides a technical solution, a waste concrete separation device for concrete processing, including: Please refer to Figure 1 , Figure 2 , the equipment housing 1, and a connection cover plate 2 provided on the top of the equipment housing 1, and a feed hopper 3 is connected to the top of the connection cover plate 2 in a communicating manner, and a flow guide seat 11 is additionally provided at the bottom of the inner cavity of the equipment housing 1;

[0028] Please refer to Figure 3 , the separation screen plate 5, is provided in the upper, central, and lower parts of the inner cavity of the equipment housing 1, and the center of the top of the separation screen plate 5 is rotatably connected to a rotating shaft 6, and stirring rods 7 are evenly provided on the surface of the rotating shaft 6;

[0029] The connecting shaft 9 is arranged between adjacent separating mesh plates 5 and is connected to the rotating shaft 6. A driving motor 17 is installed at the center of the bottom of the equipment housing 1 and is coaxially connected to the connecting shaft 9. After the waste concrete is conveyed into the equipment housing 1 through the feeding hopper 3, the waste concrete falls onto the top of the separating mesh plate 5. The driving motor 17 drives the stirring rod 7 to rotate on the top of the separating mesh plate 5 through the connecting shaft 9 and the rotating shaft 6, and stirs the waste concrete, so that the aggregate descends onto the diversion seat 11 through the separating mesh plate 5 and rolls along the diversion seat 11 to the outside of the equipment housing 1. On the one hand, the stirring rod 7 stirs the impurities, which not only avoids the phenomenon that the impurities accumulate and block on the top of the separating mesh plate 5, but also avoids the vibration of the separating mesh plate 5, which may cause accelerated wear of the screening assembly and affect the separation efficiency and effect. On the other hand, the stirring rod 7 is integrally designed in an arc shape. When driving the impurities to rotate on the top of the separating mesh plate 5, the impurities can be moved to the periphery of the top of the separating mesh plate 5 under the action of centrifugal force and fit with the inner wall of the equipment housing 1, so as to pre-treat the impurities and avoid the phenomenon that the impurities affect the separation speed and effect.

[0030] Please refer to Figure 2 , discharge grooves are provided at the corresponding positions around the top of the separating mesh plate 5 on the outside of the equipment housing 1, and side blocking plates 4 are additionally provided in the inner cavity of the discharge grooves. The side blocking plates 4 can be separated from the equipment housing 1, and the impurities concentrated around the top of the separating mesh plate 5 can be removed to the outside of the equipment housing 1 through the discharge grooves. This not only improves the separation efficiency of the separating mesh plate 5 and extends its service life, but also improves the working environment and product quality, and at the same time reduces the maintenance cost. Receiving plates 19 are installed around the lower part of the outside of the equipment housing 1, and the position relationship between the receiving plates 19 and the side blocking plates 4 corresponds. After the impurities are removed to the outside, the receiving plates 19 can collect some of the dropped impurities, avoiding the phenomenon that the impurities fall to the ground and splash around, making them difficult to find.

[0031] Please refer to Figure 4 , a positioning groove 8 is provided at the center of the bottom of the rotating shaft 6, and a positioning head 10 is installed at the center of the top of the connecting shaft 9 and corresponds to the positioning groove 8. When the rotating shaft 6 is connected to the connecting shaft 9, the positioning head 10 is inserted into the inside of the positioning groove 8. When the separating mesh plate 5 is removed and replaced, it is convenient to separate the rotating shaft 6 from the connecting shaft 9.

[0032] Please refer to Figure 5, a convex plate 12 is additionally provided at the center of the upper part of the outer side surface of the side resistance plate 4, and the convex plate 12 is rotatably connected to the equipment housing 1. The convex plate 12 is designed with a lighter upper part and a heavier lower part, and a handle 13 is installed on the outer side surface of the side resistance plate 4. The side resistance plate 4 can be fixed to the equipment housing 1 by the convex plate 12, preventing the side resistance plate 4 from being separated from the equipment housing 1 due to the impact of waste concrete, thus avoiding the occurrence of waste concrete leakage. Guide columns 14 are installed on both sides of the side resistance plate 4 and are connected to the equipment housing 1. A sliding block 15 is sleeved on the inner end of the back surface of the guide column 14 and is connected to the side resistance plate 4. A limit plate 18 is installed at the outer end of the guide column 14, and a compression spring 16 is sleeved on the surface of the guide column 14 and is in contact with the sliding block 15 and the limit plate 18 respectively. The convex plate 12 can be rotated upward, and the side resistance plate 4 can be driven to move by the handle 13, so that the sliding block 15 moves in the same direction along the surface of the guide column 14 and compresses the compression spring 16. This not only facilitates the separation operation of the side resistance plate 4 from the equipment housing 1, but also enables the side resistance plate 4 to automatically reset under the action of the compression spring 16 after the impurities are removed.

[0033] In this solution: After waste concrete is conveyed into the equipment housing 1 through the feeding funnel 3, the waste concrete falls onto the top of the separation screen plate 5. The drive motor 17 drives the stirring rod 7 to rotate on the top of the separation screen plate 5 through the connecting shaft 9 and the rotating shaft 6, and stirs the waste concrete. The stirring rod 7 is integrally designed in an arc shape. When driving the impurities to rotate on the top of the separation screen plate 5, the impurities can be moved to the periphery of the top of the separation screen plate 5 under the action of centrifugal force, so that the aggregate descends through the separation screen plate 5 onto the diversion seat 11 and rolls along the diversion seat 11 to the outside of the equipment housing 1. The side resistance plate 4 can be fixed to the equipment housing 1 by the convex plate 12. The convex plate 12 is rotated upward, and the side resistance plate 4 can be driven to move by the handle 13, so that the sliding block 15 moves in the same direction along the surface of the guide column 14 and compresses the compression spring 16. After the impurities are removed to the outside, the receiving plate 19 can collect some of the dropped impurities. After the impurities are removed, the side resistance plate 4 automatically resets under the action of the compression spring 16.
