Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fine sand recovery and treatment, and relates to fine sand recovery and treatment equipment. Specifically, it relates to a fine sand recovery screening and separation system for separating fine sand from slurry. Background Art
[0002] In the process of engineering construction and sand raw material production, some waste materials are usually generated. Due to the limited river sand resources, the cost of using river sand increases. Machine-made sand is widely used in actual production because of its low use cost. However, since the content of fine sand in machine-made sand is relatively high, when recovering machine-made sand during waste separation, the fine sand, due to its small particle size, will enter the waste water tank along with the sewage and is difficult to recycle.
[0003] Currently, in the process of fine sand extraction, the screening and separation of sand and gravel mainly rely on sieves. Due to the small particle size and high mud content of fine sand particles, these sieves often become blocked. On the one hand, the blockage of the sieve results in low screening efficiency of the equipment and reduces the fine sand recovery efficiency. On the other hand, the blocked sieve needs to be cleaned frequently, increasing the maintenance frequency and cost of the equipment. Summary of the Utility Model

[0031] In the fine sand recovery screening and separation system of the present utility model, the vibrating screen mesh adopted is designed as a hump structure. Compared with the traditional flat structure of the vibrating screen mesh, on the one hand, it is not easy to be blocked, does not need to be frequently cleaned, and only needs to be regularly maintained, saving time and effort and having a high resource utilization rate; on the other hand, the screening area is greatly increased, improving the screening efficiency; on the other hand, the number of screen holes on the surface of the vibrating screen mesh increases, enabling the processing capacity of the vibrating screen mesh to be improved and meeting the screening requirements for a large processing capacity.
[0032] In some embodiments, the vibrating screen body includes a frame sequentially connected by four connecting pieces in sequence. Support rods are respectively connected between the left and right side walls and between the front and rear side walls of the frame. The vibrating screen mesh is detachably installed on the support rods. The detachable installation between the vibrating screen mesh and the vibrating screen body is convenient for replacement when the vibrating screen mesh is worn.
[0033] In some embodiments, the vibrating screen mesh is buckled or clamped on the support rods.
[0034] In some embodiments, the mesh holes of the vibrating screen mesh are set to be not limited to circular, or oval, or square, or diamond-shaped.
[0035] It should be noted that when the mesh holes are designed as diamond-shaped, it is not easy to be blocked and the screening effect is the best.
[0036] In some embodiments, at least one vibrating screen mesh is provided.
[0037] In some embodiments, when two or more vibrating screen meshes are provided, multiple vibrating screen meshes are arranged in a queue. For example: when 15 vibrating screen meshes are provided, they are arranged in 3 rows and 5 columns (see Figure 2 ), and can also be arranged in 5 rows and 3 columns. When 10 vibrating screen meshes are provided, they are arranged in 2 rows and 5 columns (see Figure 3 ), and can also be arranged in 5 rows and 2 columns. When 5 vibrating screen meshes are provided, they are arranged in 1 row and 5 columns (see Figure 4 ), and can also be arranged in 5 rows and 1 column. When 5 vibrating screen meshes are provided, they are arranged in 3 rows and 1 column (see Figure 4 ), and can also be arranged in 1 row and 3 columns. If one of the vibrating screen meshes is worn or damaged, directly replacing the vibrating screen mesh can reduce the maintenance cost. It should be noted that the number of vibrating screen meshes can be set according to actual needs, and the arrangement method is not limited to being arranged in a queue.
[0038] In some embodiments, the above-mentioned fine sand recovery screening and separation system further includes a silo 4, which is arranged at the discharge port end of the box body 1 for storing the screened fine sand.
[0039] In some embodiments, the above-mentioned fine sand recovery screening and separation system further includes a control device. The control device includes a controller 5 and a sensing device. The controller 5 is electrically connected to the sensing device and the vibration motor 3 respectively. The sensing device is arranged at the feed port end of the box body 1 for sensing fine sand waste.

[0040] In some embodiments, referring to Figure 9 , the sensing device includes a support frame 61 and a position sensor 62 installed on the support frame 61. The position sensor 62 is electrically connected to the controller 5. Whether the waste containing fine sand enters the vibrating screen is sensed by the position sensor. When it senses that the waste containing fine sand enters the vibrating screen, the obtained signal is sent to the controller, and the controller controls the vibration motor to start working according to the signal, automatically controlling the screening and recovery of fine sand.
[0041] Specifically, in some embodiments, the support frame is installed on the box body and is located at the feed port end of the box body.
[0042] In some embodiments, continuing to refer to Figure 1 , the above-mentioned fine sand recovery screening and separation system further includes a control cabinet 7, which is placed on one side of the box body 1, and the controller is placed in the control cabinet. Placing the controller in the control cabinet is used to protect the normal operation of the controller.
[0043] The working process of the above-mentioned fine sand recovery screening and separation system is as follows:
[0044] When the sensing device senses that the waste containing fine sand enters the vibrating screen, the obtained signal is sent to the controller. The controller controls the vibration motor to start working. The waste containing fine sand falls onto the vibrating screen mesh. After screening, the fine sand enters the silo orderly through the vibrating screen mesh, and the remaining material without fine sand after screening enters the box body.
[0045] In the whole treatment process of the above-mentioned fine sand recovery screening and separation system in this embodiment, full-automatic control is realized through the controller, with simple operation, safety and reliability, and high treatment efficiency.
