Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation, in particular to a pretreatment screening device for soil remediation. Background Art

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. This is to restore the ecological function and health of the soil and ensure that the soil can continue to support plant growth and human activities.

[0003] During the soil remediation process, a pretreatment screening device is required to separate the stones with larger particle sizes from the soil in order to facilitate the subsequent soil remediation steps. The pretreatment screening devices currently on the market screen the soil and stones through a vibrating screen. During the screening process, the stones are blocked above the screen because they cannot pass through the screen. This will cause the stones to accumulate on the screen. At this time, the user needs to manually clean the stones above it to ensure the normal working environment of the pretreatment screening device. However, the manual cleaning of the stones above the screen is not only too inefficient, but also time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a pretreatment screening device for soil remediation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In addition, a preferred structure is that the screening assembly is arranged obliquely, and the bottom surface of the movable plate is adapted to be provided with a slope corresponding to the obliquely arranged screening assembly.

[0008] In addition, a preferred structure is that a movable cavity is provided through the middle of the crossbeam, the movable plate is located in the movable cavity and moves up and down, and an anti-falling plate is fixedly provided on the top of the movable plate.

[0009] In addition, a preferred structure is that support columns are vertically arranged upward at both ends of the crossbeam, and the tops of the support columns on both sides are fixedly connected to the support plate.

[0010] In addition, a preferred structure is that a plurality of springs are vertically arranged downward from the bottom of the support plate, and the other ends of the springs are connected to the top of the anti-falling plate.

[0011] In addition, a preferred structure is that when the movable plate moves downward, the spring extends downward; when the movable plate moves upward, the spring is compressed upward.

[0012] The beneficial effects of the utility model are as follows: soil and stones can be sorted through the screening device body and the screening assembly. After the sorting is completed, the stones above the screening assembly can be cleaned through the matching setting between the slider, the movable plate and the spring to ensure the subsequent normal working environment of the screening device body. This cleaning method saves time and effort and is convenient for users. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-4A pretreatment screening device for soil remediation includes a screening device body 1, a screening assembly 2 is provided at the feed port of the screening device body 1, slide rails 3 are fixedly provided on both sides of the top of the screening device body 1, and sliders 31 are movably provided on the slide rails 3. A crossbeam 4 is movably provided on the top of the screening device body 1, both ends of the crossbeam 4 are fixedly connected to the slider 31, a movable plate 5 is movably provided on the upper and lower parts of the middle of the crossbeam 4, and a support plate 71 is provided on the top of the crossbeam 4. The slide rail 3 and the slider 31 are both of the seismic-resistant type, which are common seismic-resistant slide rails and seismic-resistant sliders on the market, so they are regarded as prior art and are not elaborated in the present utility model.

[0020] Among them, a vibration motor is provided on the screening device body 1, and the user can pour the soil to be sorted on the top of the screening component 2, so as to realize the sorting of the soil, and the soil after sorting is discharged from the discharge port at the bottom of the screening device body 1. It is worth noting that this sorting device is only a pretreatment equipment for sorting soil and stones, and the sorted soil needs to undergo other treatment processes later. In addition, the specific structure and working method of the screening device body 1 and the screening component 2 are all prior arts, and do not belong to the main technical problems solved in this technical solution, so they are not elaborated in this utility model.

[0021] The screening assembly 2 is tilted, and the bottom surface of the movable plate 5 is adapted to be provided with a slope corresponding to the tilted screening assembly 2. The tilted screening assembly 2 can prevent the soil from being shaken out during screening.

[0022] The middle of the crossbeam 4 is provided with an activity cavity 41, the activity board 5 is located in the activity cavity 41 and moves up and down, and an anti-drop plate 51 is fixedly provided on the top of the activity board 5. By providing the activity cavity 41, the activity board 5 can maintain its vertical state during the up and down movement, thereby ensuring the stability of the activity board 5.

[0023] Among them, support columns 7 are vertically arranged upward at both ends of the cross beam 4, and the tops of the support columns 7 on both sides are fixedly connected to the support plate 71. The support column 7 can support the support plate 71.

[0024] Among them, a plurality of springs 6 are vertically arranged downward at the bottom of the support plate 71, and the other ends of the springs 6 are connected to the top of the anti-dropping plate 51. Through the arrangement of the springs 6, the anti-dropping plate 51 can be always pushed downward, and with the self-gravity of the movable plate 5, the bottom of the movable plate 5 can always be in contact with the screening assembly 2. When the movable plate 5 moves downward, the springs 6 extend downward; when the movable plate 5 moves upward, the springs 6 are compressed upward.

[0025] In this embodiment, when the user needs to sort the soil and stones, the crossbeam 4 can be moved to the lower side of the screening assembly 2. Then the soil is poured onto the top of the screening assembly 2, so that the soil and stones can be sorted through the screening device body 1. When the sorting is completed, the soil passes through the screening assembly 2 and is discharged from the discharge port at the bottom of the screening device body 1, while the stones are scattered on the top of the screening assembly 2 because they cannot pass through the screening assembly 2.

[0026] Furthermore, at this time, the user can control the crossbeam 4 to move to the other side through the sliders 31 on both sides. When the crossbeam 4 moves to the other side, the movable plate 5 moves synchronously with the crossbeam 4. And because the height of the screening assembly 2 gradually increases during the movement, the movable plate 5 also gradually moves upward. During the upward movement of the movable plate 5, the spring 6 is continuously compressed and provides a downward force for the movable plate 5, so that the movable plate 5 can also contact the top surface of the screening assembly 2 during the movement. In this way, the stones on the top of the screening assembly 2 can be pushed out by the movement of the movable plate 5, so that the stones on the top of the screening assembly 2 can be quickly cleaned.

[0027] In the utility model, soil and stones can be sorted by the screening device body 1 and the screening assembly 2. After the sorting is completed, the stones above the screening assembly 2 can be cleaned through the coordination between the slider 31, the movable plate 5 and the spring 6 to ensure the subsequent normal working environment of the screening device body 1. This cleaning method saves time and effort and is convenient for users.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
