Description

Technical Field

[0001] The utility model relates to the technical field of concrete recycling, and particularly relates to a residual concrete recycling device. Background Art

[0002] During the production process of a concrete mixing plant, residual and waste concrete is often generated. If the residual concrete sand and gravel and sewage are not properly treated, they will become solidified waste garbage, causing waste of resources and environmental pollution.

[0003] In a patent document with the patent publication number CN219376388U, a sand and gravel separation device for recycling residual concrete is disclosed, which relates to the field of separation devices. It includes a box body, a dilution box arranged on the box body, a plurality of rollers rotatably connected to the box body, and a screen tensioned on the outer periphery of the plurality of rollers. The dilution box is used to place sewage containing sand and gravel. An outlet is opened on the dilution box. The screen is located below the outlet. A cover plate is arranged on the dilution box, and the cover plate is used to cover the outlet. A receiving box is arranged on the box body. The screen conveys along the direction close to the receiving box. The rotation of the rollers drives the sand and gravel on the screen to move close to the receiving box, and the sand and gravel fall into the receiving box. This makes it difficult for the sand and gravel to accumulate on the screen, thereby reducing the situation of the screen being blocked by sand and gravel, and thus making it easier for the sewage to flow out from the screen holes, which is beneficial to the rapid separation of sand and gravel and sewage.

[0004] In the above technical solution, during the separation of sand and gravel, the sand and gravel adhered to each other will not be filtered sufficiently, and at the same time, the problem of screen blockage will also occur during the filtering process. Summary of the Utility Model

[0005] In view of this, the utility model provides a residual concrete recycling device, which solves the problems of insufficient sand and gravel filtration and easy screen blockage in the prior art by setting an auger and cooperating with the knocking action of the knocking component on the screen.

[0006] To solve the above technical problems, the utility model provides a residual concrete recycling device, including: an auger arranged obliquely upward, the auger having a feed inlet and a discharge outlet;

[0007] A screen is arranged on the inner bottom wall of the auger and arranged along the length direction of the auger;

[0008] A knocking component, including a knocking part and a blocking part, the knocking part is installed on the rotating shaft of the auger, and the blocking part is installed on the screen. When the auger rotates, the knocking part can hit the blocking part to make the screen vibrate.

[0009] The knocking part includes a push rod extending in the radial direction of the rotating shaft of the auger. The blocking part includes a fixed rod fixedly connected to the screen. A sleeve is fixedly arranged on the fixed rod, and a movable rod that can contact it is slidably arranged in the sleeve. The end of the movable rod extends upward and can contact the push rod. An elastic member is installed between the movable rod and the sleeve; through the vibration effect generated by the knocking assembly on the screen, materials such as gravel in the mesh holes of the screen are shaken off, avoiding screen blockage.

[0010] The knocking assembly is located at the discharge port, and the vertical cross-section of the fixed rod is conical; the knocking assembly is arranged at the discharge port to prevent concrete from adhering to the knocking assembly.

[0011] The screen is detachably arranged on the inner bottom wall of the auger; it is convenient to disassemble and replace the screen.

[0012] A diversion groove is arranged directly below the screen; by arranging the diversion groove, the fine particles and water falling from the screen are led out.

[0013] A receiving member is arranged directly below the discharge port for collecting the discharge from the discharge port; the materials discharged from the discharge port are collected by the receiving member.

[0014] The rotating shaft of the auger is hollow inside, and a plurality of through holes are evenly distributed on the rotating shaft. One end of the rotating shaft is connected to a high-pressure water pump; the blades of the auger are flushed to prevent concrete from adhering to the auger.

[0015] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0016] 1. When the auger rotates, it will drive the concrete to move inside the auger. The residual concrete will be filtered when passing through the screen. Diluted water and sand grains with reduced particles will flow down through the screen holes of the screen. Another part of the larger particles such as stones will move along with the auger towards the discharge port and finally fall from the discharge port. Under the continuous turning of the auger, the residual concrete is prevented from adhering together, resulting in insufficient filtration.

[0017] 2. During the rotation of the auger, the push rod rotates accordingly and pushes the movable rod to slide along the sleeve. When the push rod is separated from the sleeve, the movable rod rebounds under the action of the elastic member and impacts the sleeve. Since the sleeve is fixed on the fixed rod and the fixed rod is fixed on the screen, when the movable rod impacts the sleeve, the vibration will be transmitted to the screen, and the blocked gravel and other particles in the screen will fall off from the screen under the action of the vibration, avoiding screen blockage.

[0018] 3. By introducing diluted water into the rotating shaft of the auger, when diluting the residual concrete, the concrete attached to the blades of the auger can also be flushed. Description of the Drawings

Detailed Description of the Embodiments

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will combine the accompanying drawings of the embodiments of the present utility model Figures 1-5 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0026] As Figures 1-5 shown: This embodiment provides a residual concrete recycling device, including: an auger 1 arranged obliquely upward, the auger 1 having a feed inlet 11 and a discharge outlet 12;

[0027] A screen 2, arranged on the inner bottom wall of the auger and arranged along the length direction of the auger;

[0028] A knocking assembly 3, including a knocking part 31 and a blocking part 32, the knocking part 31 is installed on the rotating shaft of the auger 1, and the blocking part 32 is installed on the screen 2. When the auger 1 rotates, the knocking part 31 can hit the blocking part 32 to vibrate the screen 2.

[0029] In a specific embodiment of the present invention, the residual concrete is fed into the auger 1 through the feed port 11. During the rotation of the auger 1, the residual concrete and the dilution water are transported from the feed port 11 to the discharge port 12. During this process, the residual concrete is continuously turned over by the auger, so that the fine particles in the concrete are prevented from falling from the discharge port 12 along with the larger particles. Only the small particles and the added dilution water fall into the screen, and the screening effect is better. At the same time, when the auger rotates, the knocking part 31 continuously knocks the blocking part 32, and the vibration of the blocking part 32 shakes off the fine particles in the mesh of the screen 2, so as to avoid the clogging of the screen during the long-term operation of the present invention.

[0030] In a specific embodiment of the utility model, the knocking part 31 includes a push rod extending along the rotation axis diameter direction of the auger 1, and the blocking part 32 includes a fixed rod 321 fixedly connected to the screen 2, and a sleeve 322 is fixedly provided on the fixed rod 321. A movable rod 323 that can contact the sleeve 322 is slidably provided in the sleeve 322, and the end of the movable rod 323 extends upward and can contact the push rod.

[0031] During the rotation of the auger, the push rod rotates along with the rotation axis of the auger 1. During the rotation, the push rod contacts the movable rod 323 and pushes the movable rod 323 out of the sleeve 322 for a distance. During this process, the elastic member 324 gradually extends. When the push rod continues to push the movable rod 323 to move, the push rod will be out of contact with the movable rod 323. At this time, the movable rod 323 retracts under the action of the elastic member 324 and hits the fixed rod 321. In a specific embodiment, the elastic member 324 is a spring, one end of which is fixedly connected to the inner bottom wall of the sleeve 322, and the other end is connected to the movable rod 324. Since the fixed rod 321 is connected to the screen 2, the vibration of the screen 2 will shake off the fine particles blocked in the screen 2 to avoid clogging of the screen.

[0032] In a specific embodiment of the utility model, the knocking assembly 3 is located at the discharge port 12, and the vertical section of the fixed rod 321 is conical. The knocking assembly 3 is arranged at the discharge port 12 to prevent the knocking assembly 3 from affecting the discharge of the residual concrete. At the same time, the vertical section of the fixed rod 321 is set to be conical to prevent the residual concrete from accumulating on the fixed rod 321. Part of the concrete accumulated on the fixed rod 321 can also slide down under the vibration of the knocking assembly 3.

[0033] In another embodiment of the utility model, the screen 2 is detachably arranged on the inner bottom wall of the auger 1. In the specific implementation process, the screen 2 can be fixed on the auger 1 by screws, pins and other fixings. Since the screen 2 is a wear-prone part, by detachably arranging the screen 2 on the auger 1, the screen 2 can be replaced in time when it is damaged.

[0034] In another embodiment of the present utility model, a diversion trough 4 is provided directly below the screen 2; by arranging the diversion trough 4 below the screen 2, for the dilution water flowing down from below the screen 2, small particles flow out along the diversion trough 4, and a sedimentation pond can be arranged at the other end of the diversion trough 4 to facilitate the sedimentation of particles. The sedimentation pond is not shown in the figure. The diversion trough 4 is inclined to facilitate the outflow of the dilution water along the diversion trough 4.

[0035] In another embodiment of the present utility model, a material receiving member 5 is provided directly below the discharge port 12 for collecting the discharged materials from the discharge port 12; by arranging the material receiving member 5 at the bottom of the discharge port 12, the filtered materials at the discharge port 12 are collected. The material receiving member 5 can be a container such as a material receiving cylinder or a material receiving trough, or a conveying device such as a conveyor belt to directly convey the materials onto a transport vehicle and transport them away.

[0036] In another embodiment of the present utility model, the rotating shaft of the auger 1 is hollow inside, and a plurality of through holes 6 are evenly distributed on the rotating shaft. One end of the rotating shaft is connected to a high-pressure water pump; the dilution water can be input into the auger 1 through the feed port 11 to dilute the residual concrete, or water can be pumped into the auger 1 through the high-pressure water pump. While diluting the residual concrete, it can also wash the residual concrete adhered to the blades of the auger 1 to prevent the residual concrete from adhering to the blades of the auger 1.

[0037] The usage method of the present utility model:

[0038] When recovering the residual concrete, the residual concrete is put into the auger 1 from the feed port 1. The auger 1 rotates driven by a driving motor. At the same time, dilution water can be added into the auger 1 to reduce the possibility of the residual concrete sticking together. When the auger 1 rotates, it will drive the concrete to move inside the auger 1. When the residual concrete passes through the screen 2, it will be filtered. The dilution water and the reduced sand grains etc. will flow down through the screen holes of the screen 2. Another part of the larger particles such as stones will move towards the discharge port 12 following the auger 1 and finally fall from the discharge port 12. Under the continuous turning of the auger, the situation that the concrete adheres together and causes insufficient filtration is avoided; during the rotation of the auger 1, the push rod rotates accordingly and pushes the movable rod 323 to slide along the sleeve 322. When the push rod is disengaged from the sleeve 322, the movable rod 323 rebounds under the action of the elastic member 324 and impacts the sleeve 322. Since the sleeve 322 is fixed on the fixed rod 321 and the fixed rod 321 is fixed on the screen 2, the vibration generated when the movable rod 322 impacts the sleeve 322 will be transmitted to the screen 2, and the blocked sand and gravel etc. in the screen 2 will fall off under the action of the vibration, avoiding the blockage of the screen 2; by introducing dilution water into the rotating shaft of the auger 1, when diluting the residual concrete, it can also wash the concrete adhered to the blades of the auger 1.

[0039] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
