Description

Technical Field

[0001] This utility model relates to the field of old cement pavement material separation technology, specifically to an efficient old cement pavement material separation device. Background Technology

[0002] Used cement pavement materials refer to waste materials generated during the repair, renovation, or expansion of cement concrete pavements. These mainly include broken concrete blocks, gravel, sand, and small amounts of reinforcing steel and asphalt residue. With the rapid development of my country's transportation infrastructure, early-built cement pavements are gradually entering their major and minor repair cycles, generating tens of millions of tons of used cement pavement materials annually. If these materials are arbitrarily dumped or landfilled, they not only occupy a large amount of land resources but also cause environmental pollution due to the difficulty in the natural degradation of concrete blocks. Furthermore, they represent a serious waste of non-renewable resources such as sand, gravel, and cement. Therefore, it is necessary to screen and process used cement pavement materials.

[0003] For example, Chinese utility model patent application number 202421549430.4 discloses a waste concrete separation device for concrete processing. After being crushed, the waste concrete is fed into a separation box. The concrete falls onto a baffle plate, and under the force of gravity, it causes the baffle plate to rotate downwards, opening the feed inlet. The concrete then falls into the separation box through the feed inlet. Subsequently, under the action of an elastic element, the baffle plate rotates upwards to close the feed inlet, thus reducing the possibility of dust escaping from the feed inlet. Furthermore, the action of a stop block limits the rotation angle of the baffle plate, facilitating its closure of the feed inlet. However, this device still has certain shortcomings.

[0004] It can only perform one-stage screening of concrete waste and cannot perform multi-stage screening. It can only roughly separate materials with large particle size differences, which is not convenient for multi-size screening of old cement pavement materials according to actual conditions, thus reducing the resource utilization efficiency of old materials.

[0005] Therefore, we propose a high-efficiency separation device for old cement pavement materials to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a high-efficiency separation device for old cement pavement materials, in order to solve the problem mentioned in the background art that the current market can only perform single-stage screening of concrete waste materials, and cannot perform multi-stage screening. It can only roughly separate materials with large particle size differences, which is not convenient to realize multi-size screening of old cement pavement materials according to actual conditions, thus reducing the resource utilization efficiency of old materials.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency separation device for old cement pavement materials, comprising a base and a first screening plate. The first screening plate is mounted on the top of the base via a support plate. Support frames are mounted on both the front and rear sides of the upper surface of the base. A second screening plate and a movable frame are sequentially arranged below the first screening plate, and the second screening plate and the movable frame are connected by a connecting block. Connecting plates are mounted on both the front and rear sides below the movable frame, and pulleys are mounted below each connecting plate. A side plate is mounted on the upper left side surface of the base, and an electric push rod is mounted on the right side of the side plate.

[0008] A water tank is installed on the left side of the side panel, and a water pump is installed above the water tank. A water distribution box is installed on the upper right side of the side panel, and an atomizing nozzle is installed on the right side of the water distribution box.

[0009] Preferably, a protective plate is installed on the side of the first screening plate, and a vibration pump is installed on the protective plate. The rear side of the first screening plate is designed to be open, and the upper surface of the first screening plate is designed to be inclined.

[0010] With the above structural design, the vibration pump is installed on the protective plate and drives the inclined first screening plate to vibrate, so that the old material moves along the inclined surface during vibration. Larger particles are discharged from the rear opening. The protective plate prevents the old material from splashing and ensures that the initial screening is carried out in an orderly manner.

[0011] Preferably, a first collection box is installed on the upper surface of the base, and the first collection box is located below the opening of the first sieve plate.

[0012] With the above structural design, the first collection box is located directly below the opening of the first screening plate, receiving the larger particles of old material discharged from the first screening plate, realizing the centralized collection of primary separated materials, which facilitates subsequent processing.

[0013] Preferably, both the second sieve plate and the movable frame are designed to tilt to the right, and the mesh size of the second sieve plate is smaller than that of the first sieve plate.

[0014] With the above structural design, the mesh size of the second screening plate is smaller than that of the first screening plate, and both the second and third plates are tilted to the right. This allows the fine old material that has been screened by the first screening plate to be separated again, and even smaller particles to fall into the movable frame through the second screening plate, thus achieving multi-stage size separation.

[0015] Preferably, the upper surfaces of both the front and rear sides of the support frame are provided with sliding grooves, and the pulleys roll in the sliding grooves.

[0016] With the above structural design, the groove of the support frame provides a sliding track for the pulley, so that the movable frame and the second screening plate can move smoothly under the drive of the electric push rod, ensuring the stability of the separation process.

[0017] Preferably, the electric push rod is connected to the connecting block, and the right sides of the second screening plate and the movable frame are staggered with openings. Both the second screening plate and the movable frame are provided with baffles. The upper surface of the base is equipped with a second collection box and a third collection box, which are located below the openings of the second screening plate and the movable frame, respectively.

[0018] With the above structural design, the electric push rod pushes the connecting block, which drives the second screening plate and the movable frame to move back and forth. The staggered openings on the right side of the two respectively discharge old materials of different particle sizes into the second collection box and the third collection box below, realizing the classified collection of multi-level cement pavement old materials.

[0019] Preferably, the water pump is equipped with an inlet pipe and an outlet pipe on its front and right sides, respectively. The inlet pipe is connected to the inside of the water tank, and the outlet pipe is connected to the inside of the water distribution box.

[0020] With the above structural design, the water pump draws water from the water tank through the inlet pipe, delivers it to the water distribution box through the outlet pipe, and then sprays it out by the atomizing nozzle, which suppresses the dust generated during the screening process and improves the working environment.

[0023] Dust suppression and stable operation, optimizing the working environment: Water in the water tank is pumped to the water distribution box and formed into water mist through atomizing nozzles, effectively suppressing the dust generated during the screening process and reducing air pollution; the sliding groove and pulley of the support frame cooperate to ensure the smooth movement of the second screening plate and the movable frame, and the protective plate prevents material splashing. Multiple structures ensure operational stability and safety, reducing health risks to operators. Attached Figure Description

[0031] Please see Figures 1-5This utility model provides a technical solution: a high-efficiency separation device for old cement pavement materials, including a base 1, a support plate 2, a first screening plate 3, a protective plate 4, a vibration pump 5, a first collection box 6, a support frame 7, a second screening plate 8, a movable frame 9, a connecting block 10, a connecting plate 11, a pulley 12, a chute 13, a side plate 14, an electric push rod 15, a second collection box 16, a third collection box 17, a water tank 18, a water pump 19, an inlet pipe 20, an outlet pipe 21, a water distribution box 22, and an atomizing nozzle 23. The first screening plate 3 is installed on the top of the base 1 via the support plate 2. The protective plate 4 is installed on the side of the first screening plate 3, and the vibration pump 5 is installed on the protective plate 4. The rear side of the first screening plate 3 is open, and the upper surface of the first screening plate 3 is inclined. The structure is designed such that a vibration pump 5 is installed on a protective plate 4, driving the inclined first screening plate 3 to vibrate, causing the old material to move along the inclined surface during vibration. Larger particles are discharged from the rear opening. The protective plate 4 prevents old material from splashing, ensuring that the initial screening proceeds in an orderly manner. A first collection box 6 is installed on the upper surface of the base 1, and the first collection box 6 is located below the opening of the first screening plate 3. The first collection box 6 is located directly below the opening of the first screening plate 3, receiving the larger particles of old material discharged from the first screening plate 3, realizing the centralized collection of primary separated materials for subsequent processing. Support frames 7 are installed on both the front and rear sides of the upper surface of the base 1. A second screening plate 8 and a movable frame 9 are arranged sequentially below the first screening plate 3. Both the second screening plate 8 and the movable frame 9 are designed with a rightward inclination. The mesh size of the sieve plate 8 is smaller than that of the first sieve plate 3, and the mesh size of the second sieve plate 8 is smaller than that of the first sieve plate 3. Both the second sieve plate 8 and the movable frame 9 are designed to tilt to the right, allowing the fine old material after being screened by the first sieve plate 3 to be separated again. Smaller particles pass through the second sieve plate 8 and fall into the movable frame 9, achieving multi-stage size separation. The second sieve plate 8 and the movable frame 9 are connected by a connecting block 10. Connecting plates 11 are installed on the front and rear sides of the lower part of the movable frame 9, and pulleys 12 are installed below the connecting plates 11. The upper surfaces of the front and rear sides of the support frame 7 are provided with grooves 13, in which the pulleys 12 roll. The grooves 13 of the support frame 7 provide sliding tracks for the pulleys 12, allowing the movable frame 9 and the second sieve plate 8 to move smoothly under the drive of the electric push rod 15, ensuring the separation process. The process is stable. A side plate 14 is installed on the upper left side of the base 1, and an electric push rod 15 is installed on the right side of the side plate 14.

Both the second screening plate 8 and the movable frame 9 are equipped with baffles. The upper right side of the base 1 is equipped with a second collection box 16 and a third collection box 17. The second collection box 16 and the third collection box 17 are located below the openings of the second screening plate 8 and the movable frame 9, respectively. The electric push rod 15 pushes the connecting block 10, causing the second screening plate 8 and the movable frame 9 to move back and forth.

[0033] Working principle: When using this high-efficiency separation device for old cement road materials, firstly, the old cement road materials are put into the first screening plate 3, and the vibration pump 5 is started to drive the inclined first screening plate 3 to vibrate. The old materials move along the inclined surface under the action of vibration. Larger particles are discharged from the opening at the rear of the first screening plate 3 and fall into the first collection box 6 below to complete the primary separation. The protective plate 4 can prevent the old materials from splashing.

[0034] Fine waste material after being screened by the first screening plate 3 falls into the second screening plate 8 below. The electric push rod 15 is activated, which pushes the connecting block 10 to drive the second screening plate 8 and the movable frame 9 to move back and forth along the slide groove 13 of the support frame 7. Medium-sized waste material is discharged into the second collection box 16 from the opening on the right side of the second screening plate 8 during vibration and movement, while smaller particles pass through the second screening plate 8 and fall into the movable frame 9, and finally enter the third collection box 17 from the opening on the right side of the movable frame 9, thus achieving three-stage screening.

[0035] During the screening process, water pump 19 is activated, drawing water from water tank 18 through inlet pipe 20, and then delivering it to water distribution box 22 through outlet pipe 21. Atomized water is then sprayed out by atomizing nozzle 23 to suppress dust diffusion. The entire process, through multi-stage separation and linkage design, achieves efficient classification and recycling of waste materials while ensuring a clean working environment, thus completing a series of tasks. Content not described in detail in this specification constitutes prior art known to those skilled in the art.
