Description

Technical Field

[0001] This utility model relates to the field of sand and gravel separation technology, specifically a sand and gravel separator with a multi-stage spiral screening structure. Background Technology

[0002] The production and use of concrete generate a large amount of wastewater and waste materials. Directly discharging this wastewater and waste materials not only pollutes the environment but also wastes resources. Before recycling the stones and coarse sand from concrete wastewater, it is necessary to separate the stones, coarse sand particles, and the remaining wastewater containing fine sand and powder from the wastewater.

[0003] Most existing sand and gravel separators separate sand, gravel, and wastewater in a single process, resulting in poor separation efficiency, specifically in the separation of sand and gravel from water. The separated sand and gravel lacks the ability for secondary separation, necessitating further separation steps during subsequent use. This prolongs the concrete recycling cycle and reduces the efficiency of sand and gravel recycling. Therefore, we propose a sand and gravel separator with a multi-stage spiral screening structure.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] like Figures 1-7 As shown, this utility model provides a technical solution: a sand and gravel separator with a multi-stage spiral screening structure, comprising: a frame 1; a conveying shell 2 installed above the frame 1, a primary separation mechanism 4 installed inside the conveying shell 2, the primary separation mechanism 4 being used for at least the initial separation of sand and gravel from water, a feed hopper 3 installed on one side of the top of the conveying shell 2, a separation box 5 installed inside one side of the frame 1, and the separation box 5 being located below one end of the conveying shell 2, the separation box 5 receiving the sand and gravel conveyed by the conveying shell 2; a vibration mechanism 6 installed on both sides of the separation box 5, a guide module 7 installed between the upper sides of the separation box 5 and the frame 1, the guide module 7 being used for at least the vertical linear sliding of the separation box 5, and a secondary separation mechanism 8 installed inside the separation box 5.

[0027] In this embodiment, the system includes: a frame 1; the frame 1 includes symmetrically distributed base supports 11, and a support arm 12 is fixedly provided on the top of the base supports 11. A connecting plate 13 is provided on the top of the support arm 12. There are two longer base supports 11 and two shorter base supports 11 in the middle. There are four support arms 12, two short and two long. The connecting plate 13 is provided on one long and one short support arm 12 and is placed at an angle. The connecting plate 13 is fixed to the outside of the conveying housing 2 by bolts.

[0028] In this embodiment, a conveying shell 2 is installed on the top of the frame 1. The conveying shell 2 includes a curved part 21 located at the bottom and a flat part 22 located at the top. The curved part 21 has a semi-circular structure, which better matches the spiral blade 43. The flat part 22 at the top better stores the material and prevents the material from overflowing from the conveying shell 2. End plates 23 are fixedly installed at both ends of the conveying shell 2. A drain pipe 24 is provided on one side of the bottom end of the conveying shell 2, and water in the sand and gravel is discharged from the drain pipe 24. The conveying shell 2 is equipped with a primary separation mechanism 4, which is used for the initial separation of sand and gravel from water. A feed hopper 3 is provided on the top side of the conveying shell 2. The operator pours the material into the feed hopper 3 and it falls into the conveying shell 2 from below. The helical blades 43 are used to convey and separate the sand and gravel. The primary separation mechanism 4 includes bearing seats 41 fixed at both ends of the conveying shell 2. The bearing seats 41 are equipped with a spindle 42 located inside the conveying shell 2. The helical blades 43 are fixedly installed on the outside of the spindle 42. A drive module 44 is fixedly provided at one end of the conveying shell 2. The drive module 44 consists of a gear set and a drive motor. The drive motor drives the gear set and the spindle 42 to rotate, so that the helical blades 43 rotate inside the conveying shell 2, thereby separating water from sand and gravel while also conveying and lifting the sand and gravel further.

[0029] In this embodiment, a separation box 5 is installed inside one side of the frame 1, and the separation box 5 is located below one end of the conveying shell 2. The separation box 5 receives the sand and gravel conveyed by the conveying shell 2. The separation box 5 includes an upper surrounding shell 51 and a lower shell 52. A discharge pipe 53 is provided at the bottom of the shell 52 for discharging smaller sand and gravel particles. A discharge hopper 54 is provided on one side of the surrounding shell 51 for discharging larger sand and gravel particles. A secondary separation mechanism 8 is installed inside the separation box 5. The secondary separation mechanism 8 includes several support rods 81 fixed inside the separation box 5, and a limiting sleeve 82 is fixedly provided at the end of the support rod 81. A transmission shaft 83 is provided inside the limiting sleeve 82, and a spiral blade 84 is provided on the outer wall of the transmission shaft 83. A drive module 85 connected to the transmission shaft 83 is provided above the separation box 5. The drive module 85 consists of a gear set and a drive motor. The drive motor drives the gear set and the transmission shaft 83 to rotate, so that the spiral blade 84 rotates inside the separation box 5, thereby realizing the separation of sand and gravel of different particle sizes.

[0030] In this embodiment, vibration mechanisms 6 are provided on both sides of the separation box 5. The vibration mechanism 6 includes a fixed seat 61 fixed inside the frame 1, and a spring 62 is provided above the fixed seat 61. The top of the spring 62 is provided with an ear plate 63 fixed to the outer wall of the separation box 5. A vibration motor 64 is provided above the ear plate 63. When the secondary separation mechanism 8 is used to separate sand and gravel inside the separation box 5, the vibration motor 64 is started, which can generate vibration above the ear plate 63. Under the elastic action of the spring 62, the entire separation box 5 moves up and down, thereby causing the sand and gravel inside the secondary separation mechanism 8 to vibrate. With the rotation of the secondary separation mechanism 8 and the vibration of the separation box 5, the effect and efficiency of sand and gravel separation are improved under the dual action. Guide modules 7 are provided between the upper sides of the separation box 5 and the frame 1. The guide modules 7 are used for the vertical linear sliding of the separation box 5. The guide modules 7 include a guide rail 71 fixed to the inner side of the frame 1 and a slider 72 set on the outer wall of the separation box 5. The slider 72 is slidably inserted into the inner side of the guide rail 71. When the separation box 5 vibrates, the slider 72 on the outer side of the separation box 5 slides inside the guide rail 71 on the frame 1, thereby realizing the vertical linear lifting of the separation box 5, effectively restraining the movement path of the separation box 5, and ensuring the stability of the movement of the separation box 5.
