Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a sand and gravel separation device for concrete production. Background Technology

[0002] Sand and gravel separation devices used in concrete production play a crucial role in the concrete manufacturing process. Their main purpose is to effectively separate sand and gravel from concrete so that these materials can be reused, reducing resource waste and improving the quality and efficiency of concrete production.

[0003] A sand and gravel separation device used in concrete production typically consists of a feeding system, a separation system, a drainage system, and a recycling system. Its working principle is that concrete waste is fed into the separation system through the feeding system, and sand and gravel are separated from slurry by means of vibrating screen or hydraulic flushing. The separated sand and gravel are conveyed to a designated location by a conveyor belt, while the slurry enters the drainage system for treatment. The device has a simple operation process, a high degree of automation, and can effectively improve separation efficiency.

[0004] However, in actual use, the existing equipment lacks an effective screening structure, making it difficult for materials to fully tumble and move during screening, resulting in slow sand and gravel separation speed. This fails to meet the high-efficiency supply requirements of sand and gravel raw materials for large-scale concrete production. At the same time, it does not adequately clean the sand and other impurities adhering to the stones, affecting the screening quality. In view of this, we propose a sand and gravel separation device for concrete production. Utility Model Content

[0005] The purpose of this invention is to provide a sand and gravel separation device for concrete production, so as to solve the problems mentioned in the background art.

[0016] Compared with the prior art, this utility model provides a sand and gravel separation device for concrete production, which has the following beneficial effects:

[0017] 1. This sand and gravel separation device for concrete production, in order to further achieve efficient sand and gravel separation, is equipped with a screening component. This component, together with a servo motor, drives a straight rod to rotate through a transmission component. The swing hammers at both ends of the straight rod cause the long box to vibrate. The feed funnel feeds the material into the long box. Under the action of vibration, the material is screened on the filter plate. The isolation strips on the filter plate prevent the mixing of materials of different specifications. The sand is guided to the conveying device through the sand trough of the filter plate and the stone is discharged along the stone guide plate, thus achieving efficient sand and gravel separation.

[0018] 2. The sand and gravel separation device used in concrete production is equipped with a cleaning component to reduce the impact of impurities on concrete performance. When the straight rod rotates, the long cylinder fixed on the straight rod rotates accordingly. Multiple sets of brushes on the long cylinder are located inside the long box. During the material screening process, the brushes continuously contact the stone and brush off the sand adhering to the stone. The brushed-off sand can be discharged through the sand filter trough to prevent it from mixing into the stone. The cleaned stone has a higher purity. Attached Figure Description

Furthermore, the term "above" may also be used in certain circumstances to indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances.

[0029] Please see Figure 1 - Figure 7 This utility model provides a technical solution:

[0030] A sand and gravel separation device for concrete production includes a support 1, a conveying device 2 is provided on the outside of the support 1, a drive drum rotates under the action of a power motor, and drives the conveyor belt to move through friction, so as to transport sand, gravel and other materials placed on the conveyor belt from one end to the other end, and a feed funnel 3 is fixedly installed on the top of the support 1.

[0031] In one embodiment of this utility model, a screening component 4 is provided on the support 1. The screening component 4 includes a long funnel 41 with an opening 42. A mounting plate 43 is fixedly installed on the support 1. A cylinder 44 is fixedly installed on the mounting plate 43. One end of a dense coil helical spring 45 is fixedly installed on the mounting plate 43. A support plate 46 is fixedly installed on the other end of the dense coil helical spring 45. A connecting rod 47 is fixedly installed on the support plate 46. A long box 48 is fixedly installed on the connecting rod 47. A long plate 49 is fixedly installed on the top of the long box 48. A servo motor 410 is fixedly installed on the long plate 49. A straight rod 411 is rotatably installed on the long box 48. A connection is provided between the straight rod 411 and the output shaft of the servo motor 410. The transmission assembly 412 has swing hammers 413 fixedly installed at both ends of the straight rod 411. The bottom of the long box 48 has a filter plate 414 fixedly installed. The filter plate 414 has a separator strip 415 fixedly installed on it. The filter plate 414 has a sand filter groove 416. The support 1 has a stone guide plate 417. Multiple sets of mounting plate 43, cylinder 44, dense coil helical spring 45, support plate 46 and connecting rod 47 are provided. The transmission assembly 412 consists of two sets of pulleys and belts. The conveying device 2 consists of a conveyor belt, drive roller, redirecting roller, idler roller, tensioning device, frame and power motor. The feed hopper 3 is set above the long box 48. The conveying device 2 is set below the long box 48. The long hopper 41 and opening 42 are set below the long box 48.

[0032] In this embodiment, the construction personnel first pour the material containing sand and gravel into the long box 48 through the feed funnel 3. The servo motor 410 drives the straight rod 411 to rotate via the transmission assembly 412. Simultaneously, the swing hammers 413, fixedly installed at both ends of the straight rod 411, rotate with it. Under centrifugal force, the swing hammers 413 continuously strike the long box 48, causing it to vibrate. Meanwhile, a filter plate 414 is fixedly installed at the bottom of the long box 48, and a separator strip 415 is fixedly installed on the filter plate 414. The separator strip 415 divides the filter plate 414 into different areas to prevent... Materials of different specifications are mixed during the screening process. When the long box 48 vibrates, the materials continuously roll and move on the filter plate 414. Since the sand particles are small, they can pass through the filter plate 414 and the sand trough 416 and fall down the long funnel 41 to the conveying device 2 below. However, the stone particles are large and cannot pass through the sand trough 416. They can only be discharged along the stone guide plate 417. The long funnel 41 and the opening 42 are set below the long box 48 to collect the sand falling from the filter plate 414 and prevent the sand from scattering. This achieves efficient separation of sand and gravel and provides standard sand and gravel raw materials for concrete production.

[0033] In one embodiment of this utility model, a cleaning component 5 is provided on the straight rod 411. The cleaning component 5 includes a long cylinder 51. The long cylinder 51 is fixedly installed on the straight rod 411. Brush bristles 52 are fixedly installed on the long cylinder 51. Multiple sets of brush bristles 52 are provided. The long cylinder 51 and multiple sets of brush bristles 52 are located inside the long box 48.

[0034] In this embodiment, when the straight rod 411 rotates, the long cylinder 51 fixed on the straight rod 411 rotates accordingly. During the material screening process, the stone material moves continuously on the filter plate 414, and the brush bristles 52 continuously contact the surface of the stone material. At the same time, the continuous rotation of the brush bristles 52 can brush off the sand adhering to the stone material. The brushed-off sand material will also be discharged through the sand trough 416 under the vibration of the long box 48, preventing it from mixing into the stone material. The cleaned stone material has higher purity, reduces the impact of impurities on the performance of concrete, improves the strength, durability and other indicators of concrete, provides better quality stone material for concrete production, and ensures the quality of construction projects.

[0035] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the conveying device 2 and the servo motor 410. All standard parts used in this application can be purchased from the market.

The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art.
