According to the different media, it can be divided into wind classification and hydraulic classification. In hydraulic classification, soil and water are mixed into a solid-liquid mixed state, and the crushing efficiency is improved by softening the soil particles when they meet water. The problem with the existing technology is that the position of the soil sorting device is relatively fixed, and it cannot be dynamically adjusted according to the size of the soil particles, resulting in poor soil particle classification effect.

The device is configured to discharge small particles of soil from a second overflow port at a lower end of the surface, and comprises: an overflow liquid density detector, which is installed at the first overflow port or the second overflow port, and is used to detect the particle size of the discharged soil; a lifting component, wherein the output end of the lifting component is connected to the accommodating shell, and the inclination angle of the spiral shaft is controlled by its lifting action; wherein the lifting component adjusts the lifting action amplitude in real time according to the soil particle size detected by the overflow liquid density detector, so as to drive the soil particle size discharged from the first overflow port and the second overflow port to be within a preset particle size range.

DETAILED DESCRIPTION

[0016] The present invention will be further described below in conjunction with the accompanying drawings:

[0017] See also Figure 1-3This case provides an intelligent wet-method debulking device for soil remediation, which can adaptively adjust the inclination angle of the spiral shaft 2 according to the size of the discharged soil particles, so as to control the soil particle size discharged from the first overflow port 13 and the second overflow port 14 to always be within the preset particle size range, thereby achieving the final particle grading control effect. The preset particle size range mentioned here is an artificially set particle size range value, within which there may be one or more intervals of soil particles of different particle sizes. At the same time, the particle size range value can be changed or adjusted according to actual operating conditions. It should be pointed out that the soil referred to here is a solid-liquid mixed soil diluted by mixing soil particles of different particle sizes with clean water. Due to the difference in sedimentation velocity of the soil after solid-liquid mixing, under the rotation of the spiral shaft 2, soil particles of different particle sizes will flow out from the first overflow port 13 and the second overflow port 14 respectively, such as Figure 1 As shown, the housing 1 for assembling the spiral shaft 2 is tilted, and the spiral shaft 2 can discharge soil with larger particle sizes from the first overflow port 13 during rotation, and can discharge soil with smaller particle sizes from the second overflow port 14 at the same time. During the discharge process, the overflow liquid density detector 15 is used to detect the particle size of the discharged soil, so as to achieve the detection effect. The overflow liquid density detector 15 is also connected to the controller 10, and the data is fed back to the controller 10 in real time. The controller 10 determines the angle adjustment range of the spiral shaft 2 according to the preset particle size range value. When the inclination angle of the spiral shaft 2 is adjusted to an angle of 10°-20° with the horizontal plane, the particle size of the discharged soil can be effectively controlled and the classification effect can be achieved. The classification referred to here refers to dividing the soil particles into soil particles with larger particle sizes and soil particles with smaller particle sizes. Generally speaking, as the angle gradually increases, the particle size difference between the soil particles discharged at the first overflow port 13 and the second overflow port 14 becomes larger.

[0018] In order to further explain the improvements of this application, the following is a description of the relevant structures involved in this case:

[0019] See also Figure 1-2 ,

[0020] The intelligent wet deweighting device comprises a housing 1 and a spiral shaft 2. The housing 1 has a housing chamber 11 for accommodating and installing the spiral shaft 2. A first overflow port 13 communicating with the housing chamber 11 is formed at one end of the housing 1, and a second overflow port 14 communicating with the housing chamber 11 is formed at the other end. The spiral shaft 2 is used to discharge soil particles from the first overflow port 13 and the second overflow port 14 according to their particle sizes during its rotation. The spiral shaft 2 is tilted and discharges large particles of soil from the first overflow port 13 at the end with a higher horizontal plane, and discharges small particles of soil from the second overflow port 14 at the end with a lower horizontal plane. Generally speaking, the housing 1 used is a rectangular or cylindrical structure adapted to the length of the spiral shaft 2, which is not specifically limited in this case. Its upper end surface is set to be upper-open and form a housing chamber 11. A feed port 12 is set at the upper middle position of the housing 1. The solid-liquid mixed soil enters the housing chamber 11 through the feed port 12. In order to ensure that the solid-liquid mixed soil can be effectively discharged from the first overflow port 13 and the second overflow port 14, the feed port 12 is generally set at the middle position of the installation position of the spiral shaft 2. A motor 8 and a pulley 81 installed on the motor output shaft are set at the upper end of the housing 1. The end of the shaft body 21 of the spiral shaft 2 extends to the outside of the housing chamber 11 and is connected to the motor 8 through the pulley 81. At the same time, a motor speed detector 9 is also set on the motor 8, which can be used to detect the rotation speed of the spiral shaft 2, playing a detection and feedback effect.

[0021] In this embodiment, an overflow liquid density detector 15 is provided, and the overflow liquid density detector 15 is installed at the first overflow port 13 or the second overflow port 14, and the overflow liquid density detector 15 is used to detect the particle size of the discharged soil;

[0022] A lifting component, the output end of which is connected to the accommodating housing 1, and controls the inclination angle of the spiral shaft 2 through its lifting action;

[0023] It should be pointed out that, since the spiral shaft 2 is arranged in the accommodating chamber 11, the lifting assembly controls the position relationship of the accommodating shell 1 to adjust the spiral shaft 2. Specifically, a hydraulic component 6 is arranged at one end of the bottom of the accommodating shell 1, and a support frame 3 is fixedly connected to the bottom of the other end. A base 5 is also arranged. The hydraulic component 6 is installed on the base 5 through an externally arranged base 7. In practice, the hydraulic component 6 can be a hydraulic cylinder but is not limited thereto, and its cylinder body is fixedly connected to the base 5 through the base 7. , the end of its output shaft 61 is rotatably connected to the lower end surface of the accommodating shell 1, and a support frame 2 4 is vertically fixed at the other end of the base 5, and the support frame 2 4 is rotatably connected to the support frame 1 3, so that when the hydraulic component 6 at one end is lifted up by its output shaft 61, the accommodating shell 1 can be rotated around the connecting axis of the support frame 1 3 and the support frame 2 4. Similarly, the hydraulic component 6 can also rotate the accommodating shell 1 through the retraction action of the output shaft 61, and the effect of rotating the spiral shaft 2 to a preset tilt angle is achieved by the above;

[0024] The lifting component adjusts the lifting action amplitude in real time according to the soil particle size detected by the overflow liquid density detector 15, so as to drive the soil particle size discharged from the first overflow port 13 and the second overflow port 14 to be within a preset particle size range;

[0025] Here, those skilled in the art can understand that, before the initial use, the controller 10 provided in the present case has a preset adjustment instruction written in the storage unit of the controller 10, so as to make the automatic lifting and lifting amplitude action of the hydraulic component 6 according to the preset adjustment instruction. The lifting amplitude here can be understood as the telescopic length of the output shaft 61, and the control of the tilt angle is achieved by controlling the telescopic length;

[0026] For example, after the solid-liquid mixed soil enters the containing chamber 11 from the feed port 12, the spiral shaft 2 has an initial tilt angle at this time, and discharges the soil with different particle sizes from the first overflow port 13 and the second overflow port 14 respectively during the rotation process. During the discharge process, the overflow liquid density detector 15 detects the density of the solid-liquid mixed soil at the first overflow port 13 or the second overflow port 14 in real time, so as to determine the particle size of the discharged soil particles. The detection information at this time is sent to the controller 10, and the controller 10 calculates the current state of the spiral shaft 2 according to the preset algorithm model. At what inclination angle can the particle size of the discharged soil be within the preset range? Generally speaking, when the inclination angle is smaller (i.e., the spiral shaft 2 is closer to the horizontal), the particle size distribution of the soil discharged at the first overflow port 13 and the second overflow port 14 is closer. At this time, the inclination angle needs to be increased to drive the soil discharged from the first overflow port 13 and the second overflow port 14 to present the preset large and small particle distribution; conversely, the same applies; after the controller 10 calculates the corresponding adjustment information, it generates an adjustment instruction for controlling the telescopic length of the hydraulic component 6, and controls the hydraulic component 6 through the adjustment instruction, and finally achieves the classification effect of the soil particle size. Here we can see that the overflow liquid density detector 16 and the lifting assembly form a cooperative relationship, and the use of the controller 10 is combined to achieve the role of dynamic adjustment.

[0027] At the same time, a height detection sensor 18 can be installed at the bottom of the accommodating shell 1. During the lifting and adjustment process of the accommodating shell 1, the height position of the accommodating shell 1 can be dynamically detected in real time by the height detection sensor 18, so that the change of its inclination angle can be calculated according to the preset algorithm model. The height detection sensor 18 is electrically connected to the controller 10, and the controller 10 verifies whether the telescopic length of the hydraulic part 6 is accurate based on the height information fed back by the height detection sensor 18.

[0028] In another embodiment, the spiral shaft 2 includes a shaft body 21 arranged along the length direction of the accommodating chamber 11, the shaft body 21 having a first connecting end 211 and a second connecting end 212 away from the first connecting end 211, wherein the first connecting end 211 is connected to the pulley 81, and the second connecting end 212 is rotatably connected to one end of the accommodating shell 1, and the multiple blades 22 arranged in the direction from the first connecting end 211 to the second connecting end 212 and the shaft body 21 constitute a spiral shaft 2 with an overall configuration of a cone shape. Here, the blade 22 can be regarded as a semicircular sheet structure with a certain bending amplitude, the inner side of which is continuously bent and fixed around the circumference of the shaft body 21, and is seamlessly connected with the adjacent blades 22, and the outer side is formed with an arc-shaped edge surface 220. In this embodiment, the blade 22 close to the first overflow port 13 is regarded as the head blade 224, and the blade close to the second overflow port 14 is regarded as the end blade 223. The maximum length from the edge surface 220 of the two blades 22 to the shaft body 21 gradually increases as the head blade 224 points to the end blade 223, and forms a conical structure of the spiral shaft 2. Here, the multiple blades 22 arranged on the shaft body 21 are not limited to a specific number of settings, and at the same time, their edge surfaces 220 are equidistantly close to the bottom surface of the accommodating chamber 11. Such a close setting can effectively ensure that the solid-liquid mixed soil can flow to the first overflow port 13 and the second overflow port 14 respectively under the rotation of the spiral shaft 2;

[0029] A plurality of evenly spaced through holes 221 are provided at the end surface of the blade 22, and a plurality of evenly spaced semicircular grooves 222 are provided on the edge surface 220. The diameter range of the through holes 221 and the semicircular grooves 222 is set at 2 cm-5 cm. Such hole type and diameter range setting can facilitate the rapid discharge of moisture in coarse particles of the spiral shaft 2 during rotation, so as to reduce the moisture content of the solid-liquid mixed soil flowing out of the first overflow port 13.

[0030] Furthermore, the overflow liquid density detector 15 is installed at the second overflow port 14 or near the second overflow port 14. It should be pointed out that the accommodating chamber 11 can be divided into two interconnected first accommodating chambers 111 and second accommodating chambers 112 according to the spatial layout relationship, wherein the first accommodating chamber 111 is connected to the second overflow port 14, and the second accommodating chamber 12 is connected to the first overflow port 13. When the overflow liquid density detector 15 is only installed at one overflow port, the particle size at the other overflow port can be deduced based on the detection result at the overflow port. The reason is that since the density of the solid-liquid mixed soil injected into the accommodating shell 1 is relatively stable, under the tilt adjustment of the spiral shaft 2, the soil flowing out from the first overflow port 13 and the second overflow port 14 have a corresponding relationship in their respective particle sizes. Therefore, the effect can be achieved by only detecting the density of one of the overflow ports. On the other hand, the first overflow port 13 is arranged at an upper position toward the accommodating chamber 11, and the second overflow port 14 is arranged at a relatively lower position of the accommodating chamber. Therefore, the soil moisture content discharged from the second overflow port 14 is relatively high. Installing the overflow liquid density detector 15 here can detect the results more objectively and effectively, so as to improve the detection accuracy.

[0031] An overflow liquid flow rate detector 16 is also installed at the second overflow port 14 for detecting the flow rate of the soil. It should be noted that the overflow liquid flow rate detector 16 is also electrically connected to the controller 10, and the controller 10 controls the speed of the motor 8 according to the detection result. It should be understood that the faster the speed of the motor 8 is, the faster the flow rate of the solid-liquid mixed soil flowing out of the second overflow port 14 is, and vice versa.

[0032] Furthermore, a lining plate 17 is fixedly provided at the bottom surface of the accommodation chamber 11 . Generally speaking, the lining plate 17 can be made of tetrafluoroethylene material, but is not limited thereto, and can effectively prevent damage caused by friction at the edge of the blade 22 .

[0033] Furthermore, the taper range of the spiral shaft 2 is 1:8-1:6. This arrangement can effectively reduce the moisture content of the soil discharged from the first overflow port 13 and the energy consumption of the entire device, and effectively improve the use effect of this intelligent wet debulking device.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
