Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete slurry recycling technology, and in particular to a concrete slurry recycling device. Background Technology
[0002] In the production of precast concrete components (such as riverbank revetment panels), concrete slurry collection devices are mainly used to recover the cement slurry removed during pouring, in order to reduce waste, lower costs, and ensure construction quality.
[0003] Currently, concrete slurry collection devices are generally composed of V-shaped guide plates and installed on the side of precast concrete components. During the pouring of precast concrete components, when the concrete is vibrated or pumped, highly fluid cement slurry (containing cement, water, and admixtures) may overflow from the formwork gaps or pre-set channels. At the same time, during the static setting of precast concrete components, water in the concrete rises to form a surface slurry. This slurry layer needs to be removed to avoid insufficient surface strength. Whether the surface slurry is removed during concrete vibration, pumping, or static setting, the excess material generated is directly collected into the concrete slurry collection device and flows into the collection bucket along the concrete slurry collection device for mixing for secondary use.
[0004] Existing concrete slurry collection devices are generally installed at an angle greater than or equal to 30° to the flat ground, allowing the overflowing concrete slurry to flow into the collection bucket under its own weight. However, the overflowing concrete slurry may contain aggregate (such as gravel). When the aggregate rolls along the concrete slurry collection device towards the collection bucket, the concrete slurry adhering to the bottom of the device increases the rolling resistance, causing the aggregate to remain inside the device instead of rolling into the collection bucket. If a large amount of aggregate accumulates in the device, it can easily cause blockage, leading to overflow of the concrete slurry due to poor flow, resulting in the loss and waste of concrete slurry. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a concrete slurry recycling device, which aims to improve the problems in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a concrete residue recycling device, comprising:
[0007] A guide plate is detachably installed on one side of a precast concrete component, and a discharge plate for discharging excess concrete slurry is fixedly installed at one end of the guide plate.
[0008] The anti-clogging component is installed inside the guide plate. It can move back and forth along the inside of the guide plate. When the anti-clogging component moves back and forth, it can scrape off the excess concrete slurry attached to the inner wall of the guide plate and push the scraped excess concrete slurry into the inside of the discharge plate.
[0009] As a further description of the above technical solution:
[0010] The anti-clogging component includes mounting strips and a push plate. Mounting strips are symmetrically fixedly installed on both sides of the inner cavity of the guide plate. Each mounting strip has a receiving groove. A threaded rod is rotatably installed in the inner cavity of one receiving groove, and a guide rod is fixedly installed in the inner cavity of the other receiving groove. A drive block is threadedly fitted onto the outer wall of the threaded rod, and a guide block is slidably fitted onto the outer wall of the guide rod. A sliding groove communicating with the receiving groove is opened at the bottom of each mounting strip. A push plate is provided in the inner cavity of the guide plate. The ends of the drive block and the guide block extending outside the sliding groove are fixedly connected to the top of the push plate.
[0011] As a further description of the above technical solution:
[0012] The tops of both mounting strips are inclined toward the central axis of the inner cavity of the guide plate.
[0013] As a further description of the above technical solution:
[0014] The top two sides of the guide plate are symmetrically fixed with diversion plates. One end of the diversion plate is attached to the outer wall of the precast concrete component, and the top of the diversion plate is close to the central axis of the guide plate.
[0015] As a further description of the above technical solution:
[0016] A collection box is installed on the outside of the discharge plate. The collection box is detachably installed directly below the discharge plate, and a conveyor belt for recycling excess concrete slurry is fixedly installed in the inner cavity of the collection box.
[0017] As a further description of the above technical solution:
[0018] Both sides of the top of the conveyor belt are fixedly fitted with annular limiting strips, which are made of rubber material.
[0019] This utility model has the following beneficial effects:
[0020] In this invention, the anti-blocking component can move back and forth along the inside of the guide plate. When the anti-blocking component moves back and forth, it can scrape off the excess concrete slurry attached to the inner wall of the guide plate and push the scraped excess concrete slurry into the inside of the discharge plate, preventing the aggregate from blocking the inside of the guide plate and causing the excess concrete to overflow to the outside of the guide plate, thus avoiding the loss and waste of excess concrete slurry.

[0027] 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.
[0028] Reference Figure 1-4 One embodiment of this utility model is a concrete slurry recycling device, comprising:
[0029] The guide plate 1 is detachably installed on one side of the precast concrete structure. The guide plate 2 is symmetrically fixed on both sides of the top of the guide plate 1. One end of the guide plate 2 is attached to the outer wall of the precast concrete structure. When the concrete structure is being constructed, the excess concrete slurry generated during the vibration or pumping of the concrete falls onto the top of the guide plate 2 and flows along the top of the guide plate 2 into the interior of the guide plate 1.
[0030] The top of the diversion plate 2 moves closer to the central axis of the guide plate 1, and the excess concrete slurry can flow quickly along the inclined outer wall of the diversion plate 2 into the interior of the guide plate 1, which increases the flow rate of the excess concrete slurry into the interior of the guide plate 1 and prevents the excess concrete slurry from accumulating on the top of the guide plate 1.
[0031] A discharge plate 4 for discharging excess concrete slurry is fixedly installed at one end of the guide plate 1. The guide plate 1 is inclined, and the inclination angle of the guide plate 1 is greater than or equal to 30°. At the same time, one end of the discharge plate 4 is fixedly connected to the bottom of the guide plate 1, and the included angle between the discharge plate 4 and one end of the guide plate 1 is greater than 45° (e.g., Figure 1 As shown in the figure, the excess concrete slurry flowing into the guide plate 1 can quickly flow into the discharge plate 4, preventing the excess concrete slurry from accumulating inside the guide plate 1 and the discharge plate 4, and increasing the flow rate of the excess concrete slurry.
[0032] Both the guide plate 1 and the discharge plate 4 are designed with a V-shaped structure to provide a flow channel for the residual concrete slurry and prevent overflow during the flow of the residual concrete slurry, thus limiting the flow of the residual concrete slurry.
[0033] A collection box 6 is provided on the outside of the discharge plate 4. The collection box 6 is detachably installed directly below the discharge plate 4, and a conveyor belt 5 for recycling concrete residue is fixedly installed in the inner cavity of the collection box 6. The concrete residue flows to the top of the conveyor belt 5 through the guide plate 1 and the discharge plate 4. As the conveyor belt 5 continues to rotate, the concrete residue accumulated on the top of the conveyor belt 5 can be concentrated and discharged into the mixing equipment. The concrete residue that enters the mixing equipment can be reused after being filtered and mixed.
[0034] Both sides of the top of the conveyor belt 5 are fixedly fitted with annular limiting strips 10. The annular limiting strips 10 are made of rubber material. The two annular limiting strips 10 can limit the concrete residue accumulated on the top of the conveyor belt 5, preventing the concrete residue falling on the top of the conveyor belt 5 from falling into the collection box 6 at the two sides of the conveyor belt 5 and causing waste of concrete residue.
[0035] The inner cavity of the guide plate 1 is symmetrically fixedly installed with mounting strips 3 on both sides. Each mounting strip 3 has a receiving groove. A threaded rod 8 is rotatably installed in the inner cavity of one of the receiving grooves. A drive motor is fixedly installed on the inner wall of the guide plate 1. The power output end of the drive motor is fixedly connected to one end of the threaded rod 8 that extends to the outside of the mounting strip 3. The drive motor can provide a power source for the rotation of the threaded rod 8.
[0036] Based on the applicant's understanding of the prior art, when aggregates (such as gravel) roll along the guide plate 1 towards the collection bucket, the concrete slurry adhering to the bottom of the guide plate 1 increases the resistance to its rolling, causing the aggregates to remain inside the guide plate 1 instead of rolling into the collection device. If a large amount of aggregates accumulates in the guide plate 1, it can easily cause blockage, resulting in the overflow of residual concrete slurry in the inner cavity of the guide plate 1 due to poor flow, thus causing the loss and waste of concrete slurry.
[0037] To solve the above technical problems, a guide rod 9 is fixedly installed in the inner cavity of another receiving groove. A drive block 11 is threadedly fitted onto the outer wall of the threaded rod 8. The outer wall of the drive block 11 has a threaded hole. The drive block 11 is fitted onto the outside of the threaded rod 8 through the threaded hole. When the threaded rod 8 rotates, the drive block 11 can move along the axial direction of the threaded rod 8 under the action of the threaded hole.
[0038] A guide block is slidably sleeved on the outer wall of the guide rod 9. The bottom of both mounting strips 3 is provided with sliding grooves that communicate with the receiving groove. A push plate 7 is provided in the inner cavity of the guide plate 1. The drive block 11 and the end of the guide block extending to the outside of the sliding groove are fixedly connected to the top of the push plate 7. When the inside of the guide plate 1 is blocked by a large amount of aggregate, causing the residual concrete slurry to be unable to flow inside the guide plate 1, the threaded rod 8 rotates when the drive motor is started. The drive block 11 moves along the axis of the threaded rod 8. At this time, the push plate 7 moves together with the drive block 11. When the push plate 7 moves along the inside of the guide plate 1, it can push the aggregate accumulated in the inner cavity of the guide plate 1 to the inner cavity of the discharge plate 4. The aggregate rolls down along the discharge plate 4 to the top of the conveyor belt 5, which can clear the guide plate 1 and prevent the aggregate from blocking the inside of the guide plate 1, causing the residual concrete to overflow to the outside of the guide plate 1, thus avoiding the loss and waste of residual concrete slurry.
[0039] The guide block has a guide hole on its outer wall. The guide block is sleeved on the outside of the guide rod 9 through the guide hole. When the push plate 7 moves along the axis of the threaded rod 8, the guide block moves along the axis of the guide rod 9. The movement trajectory of the push plate 7 can be limited by the cooperation of the guide block and the guide rod 9, so as to prevent the push plate 7 from shaking or tilting when it moves, and improve the stability of the push plate 7.
[0040] The pusher plate 7 is designed with a V-shaped structure. The straight distance between the outer wall of the pusher plate 7 and the inner wall of the guide plate 1 is no more than 1 mm. The pusher plate 7 can scrape off the concrete adhering to the inner wall of the guide plate 1, preventing a large amount of concrete from accumulating on the inner wall of the guide plate 1 and reducing the volume of the residual slurry flow channel, thereby increasing the flow rate of the residual concrete slurry inside the guide plate 1.
[0041] The tops of both mounting strips 3 are inclined towards the central axis of the inner cavity of the guide plate 1. When residual concrete enters the interior of the guide plate 1, some of the residual concrete will fall onto the top of the mounting strips 3. Under the action of gravity, the residual concrete slides down along the top of the mounting strips 3 into the interior of the guide plate 1, thereby preventing the residual concrete from accumulating on the top of the mounting strips 3.
[0042] The mounting strip 3, push plate 7, threaded rod 8, and drive block 11 constitute an anti-clogging component. The anti-clogging component can move back and forth along the inside of the guide plate 1. When the anti-clogging component moves back and forth, it can scrape off the excess concrete slurry attached to the inner wall of the guide plate 1 and push the scraped excess concrete slurry into the inside of the discharge plate 4. This prevents the aggregate from clogging the inside of the guide plate 1 and causing the excess concrete to overflow to the outside of the guide plate 1, thus avoiding the loss and waste of excess concrete slurry.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
