Description

Technical Field

[0001] The invention belongs to the technical field of sand and gravel separation devices, and in particular relates to an energy-saving automatic concrete vibration sand and gravel separation system. Background Art

[0002] Concrete is widely used in the field of construction. Concrete generally contains fine aggregate and coarse aggregate. Fine aggregate is generally sand, while coarse aggregate is generally gravel. Concrete can be obtained by mixing sand and gravel with cement. In the mixing station that produces concrete, concrete is generally transported to the construction site by cement tank trucks for construction. However, the cement tank trucks cannot completely discharge all the concrete in the tank, or the concrete in the tank is not completely used up, resulting in the concrete being discarded after exceeding the best use time. At this time, the concrete in the tank needs to be poured out to prevent solidification. The discarded concrete contains a large amount of reusable resources such as sand and gravel. Separating them can reuse the resources and reduce the cost of purchasing raw materials.

[0003] The reuse of waste concrete requires the separation of sand and gravel from other materials in the concrete. The separation of concrete is generally carried out by a separator. Concrete separators are generally divided into two types: vibration separation and drum separation. Vibration separation is suitable for separating concrete sand and gravel with smaller particles such as fine sand and gravel, while drum separation is mainly suitable for separating concrete sand and gravel with larger particles. Vibration separation is a wastewater sand and gravel separation system for concrete production in Chinese patent CN114797270B, which includes a separation box, wherein a guide plate and a vibrating screen plate are movably connected and tilted in the separation box, and a sand and gravel discharge port is formed between one end of the vibrating screen plate and the inner wall of the separation box, and the guide end of the guide plate is located directly above the vibrating screen plate and is arranged away from the sand and gravel discharge port; the bottom of the guide plate is connected with a buffer mechanism to elastically buffer the impact force on the guide plate, and the buffer mechanism is connected with the separation box; a power mechanism is installed on the separation box, and the power mechanism is connected to the vibrating screen plate to drive the vibrating screen plate to screen the mixed material guided by the guide plate.

[0004] However, the concrete is not completely used up and gradually reaches the initial setting state before processing, gradually becomes viscous, and the cement gradually combines with sand and gravel. Therefore, it is easy to get stuck on the mesh of the vibrating screen plate when passing through the vibrating screen plate, causing the vibrating screen plate to gradually become blocked. Therefore, it needs to be cleaned frequently, resulting in low separation efficiency. Therefore, an energy-saving automated concrete vibration sand and gravel separation system is proposed.

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] like Figure 1-4 As shown, an energy-saving automatic concrete vibration sand and gravel separation system of the present invention comprises a shell 1, a motor 2, a sieve plate 5, a cleaning roller 17, a screw assembly and a rocker assembly, the motor 2 is arranged on the shell 1, the motor 2 is connected with a rotating shaft 3 in a transmission manner, the screw assembly is rotatably connected to the outer wall of the shell 1, the rocker assembly is arranged on the outer wall of the shell 1, the screw assembly and the rocker assembly are both connected with the rotating shaft 3 in a transmission manner, the sieve plate 5 is slidably arranged on the inner wall of the shell 1, the rocker assembly is connected to the sieve plate 5, the cleaning roller 17 is arranged on the screw assembly and the rim surface is in contact with the sieve plate 5, a plurality of teeth meshing with a plurality of meshes on the sieve plate 5 are arranged on the rim surface of the cleaning roller 17, the rocker assembly and the screw assembly respectively drive the sieve plate 5 and the cleaning roller 17 to alternately reciprocate to clean the sand and gravel blocked on the meshes of the sieve plate 5;

[0029] Since the unused concrete needs to be brought back by cement tank trucks and the concrete in the tank needs to be processed, and before the processing, the concrete in the tank has gradually reached the initial setting state and gradually become viscous, and the cement gradually combines with sand and gravel, so when passing through the vibrating screen plate 5, it is easy to get stuck on the mesh of the vibrating screen plate 5, causing the vibrating screen plate 5 to be gradually blocked, so the screen plate 5 needs to be cleaned frequently, resulting in low separation efficiency;

[0030] Therefore, by arranging a cleaning roller 17 below the sieve plate 5, the cleaning roller 17 penetrates the side wall of the shell 1 and is rotatably connected to the screw assembly, the sieve plate 5 is connected to the rotating shaft 3 through the rocker assembly, and the rotating shaft 3 is connected to the motor 2, so that the motor 2 drives the sieve plate 5 to form a horizontal reciprocating motion with a certain inclination angle, so that the concrete dropped on the sieve plate 5 separates the gravel and the sand when moving on the sieve plate 5. In this process, concrete is poured from the feed port on the top of the shell 1. As the concrete is poured, water for auxiliary separation is added to dilute the gradually solidified concrete, making it easier to separate. In the process of reciprocating movement of the sieve plate 5, the concrete is The screw assembly is transmission-connected to the rotating shaft 3, and the cleaning roller 17 is rotationally connected to the screw assembly. The screw assembly can drive the cleaning roller 17 to form a reciprocating motion, and the moving direction of the cleaning roller 17 is opposite to the moving direction of the screen plate 5, forming an alternating reciprocating motion in the horizontal direction. The teeth on the cleaning roller 17 will be inserted into the mesh holes on the screen plate 5 one by one during the rolling process, and the stuck stones or solids combined with stones and sand will be pushed away to prevent them from clogging the mesh holes. Therefore, the screen plate 5 can be cleaned by the cleaning roller 17, and the screen plate 5 and the cleaning roller 17 are both driven by a motor 2, which reduces the parts of the equipment and reduces the cost of use.

[0031] Since the general processing equipment has a large separation amount of concrete, the cleaning roller 17 also needs to continuously clean the screen plate 5. In order to realize the reciprocating motion of the cleaning roller 17, in one embodiment, the screw assembly includes a reciprocating screw 19, a slider 18 and a first bevel gear 11. The slider 18 is slidably arranged on the reciprocating screw 19, and the cleaning roller 17 is rotatably connected to the slider 18. The first bevel gear 11 is arranged at the end of the reciprocating screw 19. The second bevel gear 22 is arranged on the rotating shaft 3 for transmission. The first bevel gear 11 and the second bevel gear 22 are meshed and connected with each other through the bevel gear rod 10.

[0032] The structure of the reciprocating screw 19 and its connection with the slider 18 are both prior arts, so they are not elaborated here. The reciprocating screw 19 and the screen plate 5 are rotatably arranged on the outer wall of one side of the shell 1 at the same angle. The bevel gear rod 10 used to connect the first bevel gear 11 on the reciprocating screw 19 and the second bevel gear 22 on the rotating shaft 3 has two bevel gears at both ends. The bevel gear rod 10 is horizontally rotatably arranged on the outer wall of one side of the shell 1. Since only one reciprocating screw 19 is used to drive the slider 18, the other side of the cleaning roller 17 may not be able to withstand a large force and is prone to sagging after long-term use. Therefore, a slide bar with the same inclination angle as the reciprocating wire is set on the other side of the cleaning roller 17, and a slider 18 is also set on the slide bar, so that the slider 18 is rotatably connected to the other side of the cleaning roller 17, so that the synchronous movement of the two sides of the cleaning roller 17 can be achieved.

[0033] The rocker assembly for driving the sieve plate 5 to reciprocate comprises a third bevel gear 13, a rocker arm 12 and a sliding frame 14. The third bevel gear 13 is connected to the side wall of the housing 1, and the axis of the third bevel gear 13 is horizontal. The rocker arm 12 is eccentrically hinged to the side of the third bevel gear 13. The rocker arm 12 is hinged to the sliding frame 14. The sliding frame 14 is a semi-enclosed frame structure with two vertical rods vertically connected to the horizontal rod connected to the rocker arm 12. The two ends of the sieve plate 5 are respectively rotatably connected to the two vertical rods at the two ends of the sliding frame 14. A fourth bevel gear 23 is provided on the rotating shaft 3 for transmission, and the third bevel gear 13 is meshed with the fourth bevel gear 23.

[0034] When the rotating shaft 3 rotates under the action of the motor 2, the second bevel gear 22 and the fourth bevel gear 23 on the rotating shaft 3 both rotate. The rotation of the second bevel gear 22 and the fourth bevel gear 23 respectively drives the first bevel gear 11 and the third bevel gear 13 to rotate, thereby driving the rocker arm 12 and the reciprocating screw 19 to move alternately with each other. Through the relative movement of the two, the cleaning roller 17 can push away the stones and sand stuck on the screen plate 5 and the solids combined with hydraulic cement, so as to avoid the mesh on the screen plate 5 from being stuck.

[0035] In order to limit the sliding direction of the sliding frame 14 and prevent the sliding frame 14 from swinging unrestricted, in one embodiment, sliding grooves 20 are provided on the outer side walls of both sides of the shell 1, and the sliding frame 14 is slidably set in the sliding grooves 20. Sliding grooves 20 are respectively provided on the side walls of the shell 1 where the two vertical rods on the sliding frame 14 are located, and the vertical rods of the sliding frame 14 need to be set in the sliding grooves 20.

[0036] Since the sieve plate 5 in the above embodiment is driven by the rocker arm 12 assembly, the sieve plate 5 can only realize horizontal reciprocating motion. Although the sand and gravel can be separated, the sand and gravel cannot be completely separated due to the small and regular action force on the sand and gravel, and the cement solidified with the sand and gravel cannot be separated. In order to further improve the separation effect, in one embodiment, a vibration frame 6 is further included. The vibration frame 6 is arranged in the shell 1. Both ends of both sides of the vibration frame 6 are provided with curved grooves. Both ends of both sides of the sieve plate 5 are slidably arranged in the curved grooves. The sieve plate 5 vibrates up and down in the curved grooves as it slides horizontally.

[0037] The curved groove is a circular arc curve that reciprocates regularly or irregularly up and down along the moving direction of the screen plate 5. The curved groove is opened on both sides of the front and rear ends of the vibration frame 6, and four groups are respectively provided. When the circular shafts on both sides of the screen plate 5 are slidably set in the curved groove, the upper and lower axial surfaces of the circular shafts are slidably abutted against the curved groove. When the screen plate 5 moves left and right under the action of the rocker arm 12 assembly, the screen plate 5 will also move up and down under the limiting action of the curved groove, that is, it will move up and down while moving left and right, forming irregular vibration of the sand and gravel on the screen plate 5, which can further improve the vibration effect on the sand and gravel. The separation effect of sand and gravel under greater vibration will be more obvious. At the same time, some of the solidified cement will be shattered after vibration to avoid getting stuck in the sieve holes on the screen plate 5.

[0038] Since the round shafts on both sides of the sieve plate 5 slide and fit in the curved groove, if the device is in a low-power operating state, although it will move up and down with the curved groove, it cannot form a vibration effect. In order to form a good vibration effect even in a low-power state, in one embodiment, a plurality of springs 7 are provided on the inner wall of the housing 1, and the two ends of the vibration frame 6 are respectively provided on the springs 7;

[0039] Specifically, there are four springs 7 arranged in the shell 1, which are respectively arranged on the inner wall of the shell 1 at the four corner positions of the vibration frame 6, and the vibration frame 6 is arranged on the spring 7. Even in the low-speed state, when the rocker arm 12 assembly drives the screen plate 5 to reciprocate, the round axis of the screen plate 5 slides horizontally and up and down in the curved groove to compress the spring 7, and then release it, so that the vibration frame 6 is vibrated more through the spring 7, thereby improving the separation effect of sand and gravel.

[0040] In a general sand and gravel separation device, the separated sand and gravel can be discharged after filtering out the water, but there will still be some cement adhered to the separated sand, and the cement on the sand needs to be further cleaned to avoid affecting the performance of the concrete when the sand is reused. Therefore, in one embodiment, it also includes an auger 4, an arc tube and a fifth bevel gear 8, the auger 4 and the arc tube are both arranged in the shell 1, the side of the auger 4 is slidably abutted against the arc tube, the fifth bevel gear 8 is arranged at the end of the auger 4, and a sixth bevel gear 9 is arranged on the rotating shaft 3 for transmission, the auger 4 passes through the shell 1, and the fifth bevel gear 8 is meshed with the sixth bevel gear 9;

[0041] The fifth bevel gear 8 is driven to rotate by the motor 2 and the rotating shaft 3 connected to the motor 2, and the fifth bevel gear 8 drives the auger 4. At the same time, a plurality of drainage holes are arranged on the capstan of the auger 4. When the sand and water separated after the sand and gravel are screened by the screen plate 5 fall on the auger 4 and the arc pipe, the auger 4 rotates and gradually discharges the sand from the sand discharge port 16. The rolling of the auger 4 will turn over the sand, forming a cleaning effect similar to that of a washing machine. The cement adhered to the sand can be cleaned by constantly turning over the sand and water. When the sand is gradually transferred from one side of the auger 4 to the other side, it is basically cleaned and discharged at the same time, thereby improving the cleaning effect of the sand.

[0042] Therefore, a drain port and a sand discharge port 16 are provided on the shell 1, the drain port is connected to the arc pipe, the auger 4 is arranged from high to low from the sand discharge port 16 to the drain port, and the cleaned water flows out from the drain hole, and because the auger 4 is also arranged at an angle, the drain port is at a low position, and the sand discharge port 16 is at a high position, so as to avoid the cleaned sand from being immersed in the water again and causing pollution, and the cement cleaned from the sand is basically in powder form, which can be discharged from the drain hole on the capstan along with the water.

[0043] In the above embodiment, sand and gravel are separated by the sieve plate 5, and the separated sand falls on the arc tube and the auger 4 and is discharged through the sand discharge port 16. At the same time, the separated gravel also needs to be discharged. Therefore, in one embodiment, a stone discharge port 21 is opened on the side wall of the shell 1, and the sieve plate 5 is inclined in the shell 1. A stone discharge plate 15 is arranged in the shell 1 and below the lower end of the sieve plate 5. The stone discharge plate 15 is connected to the stone discharge port 21;

[0044] The stone discharge plate 15 is located between the sieve plate 5 and the auger 4, and the stone discharge plate 15 is at the lower end of the sieve plate 5. After the stones are separated, they are on the sieve plate 5. Under the action of vibration, the sieve plate 5 gradually moves the stones to a lower place until they fall on the stone discharge plate 15. The stone discharge plate 15 is connected with the stone discharge port 21. The section from the stone discharge plate 15 to the stone discharge port 21 is also inclined. Therefore, the stones are discharged from the stone discharge port 21 after falling on the stone discharge plate 15.

[0045] Working principle: concrete is poured into the shell 1 from the feed port while water is continuously added, so that the concrete and water are diluted and fall on the sieve plate 5, the sieve plate 5 is slidably arranged on the vibration frame 6, and the sieve plate 5 is reciprocated by the rocker assembly, and the curved groove on the vibration frame 6 makes the sieve plate 5 vibrate up and down during the reciprocating motion, and a spring 7 is arranged under the vibration frame 6 to increase the vibration effect, so that the low-frequency vibration is converted into a high-frequency vibration, and the sand and gravel are better separated by the high-frequency vibration, and the gravel is screened out by the sieve plate 5 and discharged from the stone discharge port 21 after falling on the stone discharge plate 15, and the sand falls on the arc tube, and the auger 4 turns the sand by rotating, so that the cement adhered to the sand is further cleaned, and the cleaned sand is discharged from the sand discharge port 16 by the rotation of the auger 4, and the cleaning water carries the cleaned powdered cement through the drainage hole on the capstan and is discharged from the drainage port, the above steps avoid the sieve holes on the sieve plate 5 from being blocked, and at the same time improve the separation efficiency and cleaning effect of sand and gravel.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
