Description

Technical Field

[0001] The utility model relates to the field of soil detection for abandoned sites, and particularly relates to a centrifugal soil detection sample preparation screening device for abandoned sites. Background Technique

[0002] Soil detection for abandoned sites is a comprehensive process aimed at evaluating the quality of the soil within the site, especially the presence of harmful substances or pollution, and the potential risks these substances may pose to the environment and human health. When conducting soil detection for abandoned sites, a screening device is required to separate different particle size particles in the soil sample, so as to prepare a soil sample that meets the detection requirements.

[0003] Most of the existing soil detection sample preparation screening devices for abandoned sites can only screen out large particle substances in the soil and cannot perform precise multi-stage screening, thus unable to meet the screening requirements for soils of different particle sizes. At the same time, they cannot accurately detect the soil of abandoned sites and cannot correctly evaluate the quality of the soil of abandoned sites.

[0004] Therefore, it is necessary to invent a centrifugal soil detection sample preparation screening device for abandoned sites to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a centrifugal soil detection sample preparation screening device for abandoned sites. By pouring the soil into the inner screening cylinder in the screening box, then turning on the drive motor switch to drive the rotation of the second transmission rod and the first transmission rod, the rotation of the first transmission rod drives the entire inner screening cylinder and the outer screening cylinder to rotate centrifugally. The large particle soil will be screened out by the inner screening cylinder and then discharged through the thick holes in the inner ring of the base into the inner discharge port. The smaller particles enter the inner screening cylinder and the outer screening cylinder for further centrifugal screening, and the soil screened out at this layer falls into the discharge bin and is discharged. Finally, the soil screened by centrifugation is in the screening box and is discharged through the second discharge port, so as to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A centrifugal soil detection sample preparation screening device for abandoned sites, including a screening box;

[0007] An inner screening cylinder and an outer screening cylinder are arranged inside the screening box for screening the soil of abandoned sites. Support frames are fixedly installed around the screening box. A base is fixedly installed below the inner screening cylinder and the outer screening cylinder. Thick holes are formed on the surface of the inner ring of the base, and fine holes are formed on the surface of the outer ring of the base. A first transmission rod is fixedly installed inside the base, and a convex block is fixedly installed above the first transmission rod;

[0008] The discharge bin is arranged below the screening box and is used for discharging the soil in the inner screening cylinder. An inner discharge port is opened on the lower surface of the screening box, a first discharge outlet is opened on one side below the discharge bin, and a second discharge outlet is opened on the other side surface below the screening box;

[0009] The upper cover is installed above the screening box. Bolts penetrate through both sides of the upper cover. A feed port is opened above the upper cover, and the feed port is used for pouring soil. A bracket is fixedly installed on one side of the screening box, and a driving motor is fixedly arranged at the upper end of the bracket. The output end of the driving motor is fixedly installed with a second transmission rod.

[0010] Preferably, the surface of the inner screening cylinder is a coarse mesh, and the surface of the outer screening cylinder is a fine mesh.

[0011] Preferably, the inner screening cylinder is used in cooperation with the coarse holes in the base, and the outer screening cylinder is used in cooperation with the fine holes in the base.

[0012] Preferably, the inner discharge port is communicated with the inside of the inner screening cylinder, and the discharge bin is communicated with the inside of the outer screening cylinder.

Through the settings of the screening box, inner screening cylinder, outer screening cylinder, base, coarse holes, fine holes, first transmission rod, inner discharge port, discharge bin, first discharge outlet and second discharge outlet, multi-level screening of soil from multiple waste sites can be realized, which not only improves the screening efficiency, but also meets the requirement of screening out soils of different sizes. By pouring the soil into the inner screening cylinder in the screening box, then turning on the driving motor switch to drive the second transmission rod and the first transmission rod to rotate, the rotation of the first transmission rod drives the entire inner screening cylinder and outer screening cylinder to rotate centrifugally. The large-particle soil is screened out by the inner screening cylinder and then falls into the inner discharge port through the coarse holes in the inner ring of the base and is discharged.

[0027] The present utility model provides a centrifugal waste yard soil detection sample preparation screening device as Figures 1-5 shown, including a screening box 1;

[0028] The inner screening cylinder 3 and the outer screening cylinder 4 are arranged inside the screening box 1 and are used for screening the soil of the abandoned site. The four sides of the screening box 1 are fixedly installed with support frames 2. The lower parts of the inner screening cylinder 3 and the outer screening cylinder 4 are fixedly installed with a base 5. The inner surface of the inner circle of the base 5 is provided with thick holes 6, and the outer surface of the outer circle of the base 5 is provided with fine holes 7. A first transmission rod 8 is fixedly installed inside the base 5, and a convex block 9 is fixedly installed above the first transmission rod 8;

[0029] The discharge bin 11 is arranged below the screening box 1 and is used for discharging the soil in the inner screening cylinder 3. An inner discharge port 10 is opened on the lower surface of the screening box 1, a first discharge outlet 12 is opened on one side below the discharge bin 11, and a second discharge outlet 13 is opened on the other side surface below the screening box 1;

[0030] The upper cover 14 is installed above the screening box 1. Bolts 15 penetrate through both sides of the upper cover 14. A feed inlet 16 is opened above the upper cover 14, and the feed inlet 16 is used for pouring in the soil. A support 17 is fixedly installed on one side of the screening box 1, a driving motor 18 is fixedly arranged at the upper end of the support 17, and an output end of the driving motor 18 is fixedly installed with a second transmission rod 19. By pouring the soil into the inner screening cylinder 3 in the screening box 1, then turning on the switch of the driving motor 18, driving the second transmission rod 19 and the first transmission rod 8 to rotate, driving the entire inner screening cylinder 3 and the outer screening cylinder 4 to rotate centrifugally through the rotation of the first transmission rod 8. The large-particle soil is screened out by the inner screening cylinder 3 and then falls into the inner discharge port 10 through the thick holes 6 in the inner circle of the base 5 and is discharged. The smaller particles enter the inner screening cylinder 3 and the outer screening cylinder 4 for continuous centrifugal screening, and the soil screened out at this layer falls into the discharge bin 11 and is discharged. Finally, the soil screened centrifugally is in the screening box 1 and is discharged through the second discharge outlet 13.

[0031] As Figure 2 shown, the surface of the inner screening cylinder 3 is a coarse mesh, and the surface of the outer screening cylinder 4 is a fine mesh. By using the inner screening cylinder 3 and the outer screening cylinder 4 with coarse and fine meshes, the soil can be classified and screened, thereby improving the screening efficiency.

[0032] As Figure 2 shown, the inner screening cylinder 3 is used in cooperation with the thick holes 6 in the base 5, and the outer screening cylinder 4 is used in cooperation with the fine holes 7 in the base 5. The soil remaining after being screened by the inner screening cylinder 3 is discharged through the thick holes 6 in the base 5. At the same time, the soil between the inner screening cylinder 3 and the outer screening cylinder 4 is also discharged through the fine holes 7 in the base 5.

[0033] As Figure 2 and Figure 3As shown, the inner discharge port 10 is internally connected to the inside of the inner screening cylinder 3, and the discharge bin 11 is internally connected to the inside of the outer screening cylinder 4. The soil remaining after screening by the inner screening cylinder 3 enters the inner discharge port 10 and is discharged, while the soil screened between the inner screening cylinder 3 and the outer screening cylinder 4 falls into the discharge bin 11 and is discharged.

[0034] As Figure 4 and Figure 5 shown, a spiral blade 20 is fixedly installed on the outside of the second transmission rod 19, and a groove 21 is formed on the lower surface of the second transmission rod 19. By pouring soil from the feed port 16, the drive motor 18 drives the second transmission rod 19 and the external spiral blade 20 to rotate, crushing some agglomerated soil to avoid clogging and making it inconvenient for screening.

[0035] As Figure 2 and Figure 5 shown, the convex block 9 is set as a square, and the convex block 9 is movably sleeved in the groove 21 below the second transmission rod 19. By sleeving the groove 21 below the second transmission rod 19 on the convex block 9 on the first transmission rod 8, the upper cover 14 can be easily disassembled for subsequent cleaning of the inside of the screening box 1.

[0036] The working principle of this utility model: First, connect to the external power supply, then turn on the switch of the drive motor 18 to drive the second transmission rod 19 and the external spiral blade 20 to rotate. At the same time, the rotation of the second transmission rod 19 drives the first transmission rod 8 below and the external inner screening cylinder 3 and outer screening cylinder 4 to rotate. Next, pour the soil from the waste yard into the feed port 16, and use the drive motor 18 to drive the second transmission rod 19 and the external spiral blade 20 to rotate to crush some agglomerated soil to avoid clogging and making it inconvenient for screening. Then the soil enters the inner screening cylinder 3, and through the overall centrifugal rotation of the inner screening cylinder 3 and the outer screening cylinder 4, the soil is screened. The large-particle soil will be screened out by the inner screening cylinder 3, and then fall into the inner discharge port 10 through the thick holes 6 in the inner ring of the base 5 and be discharged. The smaller particles are screened into the inner screening cylinder 3 and the outer screening cylinder 4 for further centrifugal screening, and the soil screened out at this layer falls into the discharge bin 11 and is discharged through the first discharge port 12. Finally, the soil is centrifugally screened in the screening box 1 and discharged through the second discharge port 13. Before screening, three collection frames are placed under the inner discharge port 10, the first discharge port 12, and the second discharge port 13 to facilitate the collection of the screened soil. Finally, when the soil screening is completed, turn off the switch of the drive motor 18, and finally cut off the external power supply. Just like this, the use process of this centrifugal soil detection and sample preparation screening device for waste yards is completed.

[0037] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
