Description

Technical Field

[0001] The invention relates to the technical field of soil pollution treatment, and in particular to a contaminated soil treatment stirring mechanism. Background Art

[0002] With the progress of urbanization, pollutants are discharged into the soil through various channels. The treatment of soil pollutants has always been the focus of environmental protection work. The leaching method is usually used to treat soil pollutants. The contaminated soil is pulped after pretreatment, and chemicals are added to the soil. The mixture is stirred to allow the soil and chemicals to fully react, and the pollutants in the soil are washed away. The soil is then concentrated and dehydrated to achieve mud-water separation.

[0003] The Chinese patent with the announcement number CN219771944U discloses a geotube filtration and dehydration device with a high-pressure rotary jet device, including a frame, a geotube filter fixedly installed between the top plate and the bottom plate of the frame, and a drill rod entering the geotube filter through the through hole on the top plate, wherein the drill rod is provided with a top opening for connecting an air pipe to pass high-pressure gas, and one or more air holes are opened around the end of the drill rod for spraying high-pressure gas. While the drill rod rotates and stirs the soil in the geotube through the stirring blade at the bottom, high-pressure gas is poured into the rotating hollow drill rod, and the high-pressure gas is ejected and discharged in the horizontal direction through the air hole at the end of the drill rod, so that the high-pressure gas penetrates the soil and discharges the moisture in the soil through the geotube, and the soil particles are still in the geotube, so that the soil is simultaneously subjected to high-pressure dehydration during the stirring process, so that the dehydration efficiency of the soil is improved.

[0004] Although the above-mentioned dehydration equipment improves the dehydration effect, when the high-pressure gas is ejected through the pores of the drill pipe to shear the soil, the injection path of the high-pressure gas will form a priority channel in the soil, so that the water is only discharged along the priority channel. The dehydration effect of the part of the soil that is not affected by the high-pressure gas injection is not obvious. The effective coverage area of ​​the drill pipe is small, and the stirring effect on the soil is limited, making it difficult to stir the soil evenly.

DETAILED DESCRIPTION

[0028] The following is a description of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0029] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions that the present invention can be implemented, so they have no substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effects that the present invention can produce and the purposes that can be achieved. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of the relative relationship should also be regarded as the scope of the implementation of the present invention without substantial changes in the technical content. The specific structure can be described with reference to the drawings of the patent application.

[0030] In order to solve the above technical problems, the present invention discloses a contaminated soil disposal mixing mechanism, such as Figure 1 and Figure 3 As shown, it includes: a disposal bin 1 and a dehydration injection assembly 2, the dehydration injection assembly 2 includes a drill rod 201, the drill rod 201 is used to horizontally inject high-pressure gas into the disposal bin 1, and the contaminated soil disposal mixing mechanism also includes a mixing assembly 3; the disposal bin 1 includes a frame 101 and a geotube 102, the geotube 102 is arranged on the surrounding walls of the frame 101, the top of the frame 101 is provided with a feed inlet 103, and the bottom of the frame 101 is provided with a discharge port 104; the drill rod 201 is arranged in the frame 101 to be lifted up and down; the mixing assembly 3 is arranged in the frame 101, and the mixing assembly 3 includes a rotating seat 301, a driven disc 302, a wire rope 303, a guide disc 304 and a first motor 305, and the driven disc 302 is rotated. The rotating seat 301 is arranged below the top wall 1011 of the frame 101, and is rotatably arranged at the bottom of the frame 101. The guide disc 304 is arranged between the driven disc 302 and the rotating seat 301. The guide disc 304 is provided with a spiral guide groove 3041, and the guide groove 3041 extends from the outer circumference of the guide disc 304 to the inner circumference. One end of the wire rope 303 is fixedly connected to the driven disc 302, and the other end of the wire rope 303 is fixedly connected to the rotating seat 301 after passing through the guide groove 3041. The output shaft of the first motor 305 is fixedly connected to the rotating seat 301. The first motor 305 drives the rotating seat 301 to rotate in the horizontal direction. The rotation center of the rotating seat 301 and the rotation center of the driven disc 302 are on the same vertical line.

[0031] Specifically, when the rotating seat 301 rotates, the wire rope 303 rotates with the rotating seat 301. Since one end of the wire rope 303 is fixedly connected to the rotating seat 301, and the other end of the wire rope 303 is fixedly connected to the driven disc 302, the wire rope 303 rotates and is tightened in the guide disc 304, pulling the driven disc 302 to rotate along, thereby stirring and vertically cutting the soil in the disposal bin 1, so that the soil is stirred evenly. At the same time, during the dehydration process, the wire rope 303 cuts the soil in the vertical direction, so that the tight structure formed between the soil particles is destroyed, thereby preventing the soil from sticking together and causing a decrease in dehydration efficiency.

[0032] After removing a part of the water, the concentration of solid particles in the soil increases, and a tighter structure is formed between the particles. The fluidity of the soil in the disposal bin 1 is relatively poor, resulting in a small change in the relative position between the soil in the disposal bin 1 and the drill rod 201. The high-pressure gas ejected from the drill rod 201 can only be ejected to part of the soil, so the dehydration efficiency of part of the soil can only be improved. In the present invention, the length direction of the steel wire rope 303 and the direction of the high-pressure gas ejected from the drill rod 201 are staggered, which can intermittently prevent the high-pressure gas from forming a priority channel in the soil. With the stirring of the steel wire rope 303, the position of the soil in the disposal bin 1 continues to change, that is, the soil corresponding to the position of the high-pressure gas ejected from the drill rod 201 is constantly changing. Even if the position of the drill rod 201 in the vertical direction remains unchanged, the high-pressure gas ejected from the drill rod 201 can also form a dehydration channel for different soils, making it easier to separate the residual water in different soils, improving the overall dehydration efficiency of the soil, and effectively removing the residual water in the soil, solving the technical problem that the existing soil leaching device cannot quickly remove the residual water in the soil.

[0033] The guide groove 3041 plays a role in sliding and guiding the steel wire rope 303. Preferably, the guide groove 3041 is in a clockwise spiral shape, such as Figure 6As shown, the direction indicated by the arrow is clockwise. When the rotating seat 301 rotates counterclockwise, the wire rope 303 moves along the guide groove 3041 from the inner circumference to the outer circumference of the guide disc 304, so that the wire rope 303 moves to the outer circumference of the guide groove 3041, and the rotation radius of the wire rope 303 increases, thereby expanding the cutting range of the wire rope 303 in the vertical direction. When the wire rope 303 rotates counterclockwise and is tightened in the guide disc 304, it pulls the driven disc 302 to rotate counterclockwise. When the wire rope 303 abuts against the groove wall of the guide groove 3041 on the outer circumference, the rotating seat 301 continues to rotate counterclockwise, and the wire rope 303 continues to rotate with the rotating seat 301 to push the guide disc 304 to rotate counterclockwise. When the rotating seat 301 rotates clockwise, the steel wire 303 moves along the guide groove 3041 from the outer circumference to the inner circumference of the guide disc 304, so that the steel wire 303 moves to the inner circumference of the guide groove 3041, and the rotation radius of the steel wire 303 is reduced, thereby reducing the cutting range of the steel wire 303 in the vertical direction; the steel wire 303 rotates clockwise and pulls the driven disc 302 to rotate clockwise when it is tightened in the guide disc 304. When the steel wire 303 and the groove wall of the guide groove 3041 on the inner circumference are against each other, the rotating seat 301 continues to rotate clockwise, and the steel wire 303 continues to rotate with the rotating seat 301 to push the guide disc 304 to rotate clockwise. By setting the guide disc 304, the vertical cutting range of the steel wire 303 in the disposal bin 1 can be adjusted, and the cutting range of the steel wire 303 can be set accordingly according to the conversion of the process and the change of fluidity of the soil during the dehydration process.

[0034] The slurried soil is injected into the disposal bin 1 from the feed port 103. The pore structure of the geotube bag 102 allows liquid to pass through. The water in the soil gradually seeps out from the geotube bag 102 on the surrounding walls. At this time, the drill rod 201 and the first motor 305 are turned on. When the drill rod 201 rotates, high-pressure gas is sprayed into the disposal bin 1 to accelerate the separation of the water from the soil. The first motor 305 drives the rotating seat 301 to rotate, and the wire rope 303 rotates with the rotating seat 301. When the wire rope 303 rotates, it pulls the driven disc 302 to rotate, so that the wire rope 303 cuts the soil, destroys the soil structure, and improves the dehydration efficiency. After dehydration is completed, the discharge port 104 is opened to discharge the soil.

[0035] Preferably, a transport passage for a transport vehicle to enter is provided below the frame 101 of the disposal bin 1. During discharge, the transport vehicle can enter the transport passage and be located below the discharge port 104, and the soil can be directly discharged onto the transport vehicle.

[0036] Preferably, if Figure 2As shown, a collection pool 9 is provided below the frame 101 of the disposal bin 1. The collection pool 9 is provided with a slope for the transport vehicle to enter. A vertical baffle 901 is detachably provided in the collection pool 9. The baffle 901 separates the collection pool 9 from a water storage area 902. Before adding the reagent for elution by elution, the baffle 901 is used to separate the collection pool 9 from the water storage area 902, and the slurried soil is added to the disposal bin 1. The reagent is added to the soil and the stirring component 3 is turned on to fully mix the reagent with the soil to achieve elution by elution, so that the pollutants in the soil are separated from the soil and enter the water body. After the elution is completed, the dehydration spray component 2 is turned on for dehydration. The water in the soil seeps out of the geotube bag 102 and flows into the water storage area 902. After the dehydration is completed, the water in the water storage area 902 is emptied by using a pump pipe, and the baffle 901 is removed. At this time, the transport vehicle can enter the transport channel from the slope to transport the dehydrated soil away, which is convenient for the treatment of the treated water and soil separately.

[0037] It should be noted that the structure of the drill rod 201 spraying high-pressure gas is the same as the structure of the drill rod spraying high-pressure gas in the Chinese patent publication number CN219771944U, which will not be described in detail here.

[0038] Furthermore, if Figure 3 and Figure 4 As shown, in one embodiment of the present invention, a cylinder 4 is fixedly provided on the top wall 1011, and the cylinder 4 vertically passes through the center of the top wall 1011 and the driven disc 302, and the driven disc 302 is movably sleeved on the cylinder 4, and the drill rod 201 passes through the cylinder 4, and the bottom end of the cylinder 4 is fixedly connected with a horizontally arranged bottom plate 401, and a spring 402 is arranged outside the cylinder 4, and the bottom end of the spring 402 is fixedly connected to the bottom plate 401, and the top end of the spring 402 is fixedly connected with a horizontally arranged top plate 403, and the top plate 403 is sleeved on the cylinder 4, and the top plate 403 can slide up and down relative to the cylinder 4, and the upper surface of the top plate 403 is against the lower surface of the driven disc 302.

[0039] The upper surface of the top plate 403 abuts against the lower surface of the driven disc 302, and the top plate 403 can support the driven disc 302. When the rotating seat 301 rotates, the wire rope 303 rotates around the central axis of the rotating seat 301, pulling the driven disc 302 to rotate accordingly, and the wire rope 303 will generate a downward pulling force on the driven disc 302. The wire rope 303 close to the outer peripheral side of the driven disc 302 will generate a downward pulling force on the outer peripheral side of the driven disc 302. When the outer peripheral side of the driven disc 302 is subjected to excessive pulling force, it will tend to bend downward and deform. At this time, the driven disc 302 moves downward to squeeze the top plate 403, the spring 402 is compressed, and the driven disc 302 and the top plate 403 move downward, which can slow down the deformation trend of the driven disc 302 and extend the service life of the driven disc 302.

[0040] Furthermore, if Figures 3 to 5As shown, in one embodiment of the present invention, a pulley 3021 is provided on the upper surface of the driven disc 302 , and an annular groove 1012 is provided on the lower surface of the top wall 1011 , and the pulley 3021 and the annular groove 1012 are slidably matched.

[0041] Specifically, the pulley 3021 is symmetrically arranged with the center of the driven disc 302 as the center. When the wire rope 303 rotates to pull the driven disc 302 to rotate, the pulley 3021 set on the driven disc 302 slides in the annular groove 1012, making the rotation of the driven disc 302 smoother, reducing the contact friction between the driven disc 302 and the top wall 1011 when rotating, and extending the service life of the driven disc 302.

[0042] Furthermore, if Figure 3 As shown, in one embodiment of the present invention, a plurality of steel wire ropes 303 are provided, and the plurality of steel wire ropes 303 are arranged at intervals between the rotating seat 301 and the driven disc 302; the rotating seat 301 is in the shape of a cone with the top facing upward, and the steel wire ropes 303 are connected to the conical surface of the rotating seat 301.

[0043] Specifically, four guide grooves 3041 are provided on the guide disc 304, and three steel wires 303 are interlaced through the guide grooves 3041 from the inner circumference to the outer circumference. The steel wires 303 arranged at intervals can simultaneously stir and cut the soil on the outer and inner circumference sides of the guide disc 304, thereby expanding the action range of the stirring assembly 3. When discharging, the soil in the disposal bin 1 can fall along the conical surface, effectively improving the smoothness of the discharging and reducing the residual soil in the disposal bin 1 when discharging.

[0044] Furthermore, if Figure 3 As shown, in one embodiment of the present invention, a steel pipe 3031 is sleeved on the section of the steel wire rope 303 below the guide disc 304 ; a clip 3032 is fixedly connected to the steel wire rope 303 below the guide disc 304 , and the clip 3032 is located above the steel pipe 3031 , and the clip 3032 is used to support the guide disc 304 .

[0045] When the rotating seat 301 rotates to move the wire rope 303 toward the inner circumference of the guide disc 304, the radius of rotation of the wire rope 303 decreases, and the wire ropes 303 may be entangled. During the rotation process, the wire ropes 303 are prone to rub against each other, which will affect the service life of the wire ropes 303. The steel pipe 3031 is sleeved on the wire rope 303 to prevent the wire rope 303 from rubbing against each other and causing the wire rope 303 to break, thereby extending the service life of the wire rope 303 and reducing the possibility of entanglement of the wire rope 303, thereby ensuring the normal operation of the equipment.

[0046] A clip 3032 is provided below the guide disc 304, and the distance between the clip 3032 and the upper end of the wire rope 303 is fixed, so that the guide disc 304 can be supported on the clip 3032. At the same time, when the rotating seat 301 rotates clockwise and counterclockwise, the guide disc 304 will move up and down with the clip 3032 when the wire rope 303 switches between the stretched and relaxed states.

[0047] Furthermore, if Figure 3 and Figure 6 As shown, in one embodiment of the present invention, a through hole 3042 is opened in the center of the guide disc 304, and the drill rod 201 extends to the bottom of the guide disc 304 through the through hole 3042; the through hole 3042 is a star-shaped hole, and the drill rod 201 is provided with a star-shaped wheel 2011, which cooperates with the through hole 3042.

[0048] When the soil moisture content is low, the fluidity of the soil is low, and the guide disc 304 is difficult to rotate due to the large pressure of the soil. The wire rope 303 needs a large force to drive the guide disc 304 to rotate. The wire rope 303 may be stuck in the guide groove 3041 and cannot continue to rotate, which may easily cause the first motor 305 to be damaged due to excessive torque. When the drill rod 201 is raised and lowered, when the star wheel 2011 and the through hole 3042 are at the same height, the rotating seat 301 and the drill rod 201 rotate in the same direction at the same speed, the star wheel 2011 can cooperate with the through hole 3042, and the guide disc 304 rotates with the rotating seat 301 and the drill rod 201 under the drive of the wire rope 203 and the star wheel 2011, so that the rotation of the guide disc 304 is partially borne by the drill rod 201. The load pressure of the first motor 305 is reduced and the stability of the equipment is improved.

[0049] Furthermore, if Figure 3 and Figures 7 to 9 As shown, in one embodiment of the present invention, an auxiliary disk 5 is provided above the rotating seat 301, and the auxiliary disk 5 includes a fixed ring 501 and a movable ring 502. The fixed ring 501 is fixedly connected to the inner wall of the frame 101, and an annular groove 5011 is provided on the inner wall of the fixed ring 501. A plurality of spokes 503 are fixedly provided symmetrically on the movable ring 502, and the spokes 503 are connected by a circular ring 504. One end of the spoke 503 away from the circular ring 504 is slidably matched with the annular groove 5011, and a driven rope 505 is connected between the movable ring 502 and the edge of the guide disk 304.

[0050] When the guide disc 304 rotates, the driven rope 505 rotates with the guide disc 304, and the driven rope 505 pulls the movable ring 502 to rotate relative to the fixed ring 501. The spokes 503 on the movable ring 502 slide along the annular groove 5011, and the spokes 503 stir the soil in the horizontal direction. The moisture in the soil will gather downward under the action of gravity. The spokes 503 stir the soil at the bottom of the disposal bin 1, so that the moisture adhering to the soil is separated, thereby improving the dehydration efficiency of the soil at the bottom of the disposal bin 1. At the same time, after the dehydration is completed, the fluidity of the soil is low, and the soil at the bottom of the disposal bin 1 is stirred, so that the soil at the bottom of the disposal bin 1 is quickly discharged from the discharge port 104, and the soil is prevented from blocking the discharge port 104. The driven rope 505 rotates and cuts the soil at the bottom of the disposal bin 1, expanding the range of stirring and cutting in the disposal bin 1 and improving the dehydration efficiency of the soil.

[0051] Furthermore, if Figure 3 As shown, in one embodiment of the present invention, a blanking plate 6 is arranged below the fixing ring 501, and the blanking plate 6 is provided with an inclined surface inclined toward the discharge port 104, the lower end of the blanking plate 6 is connected to the discharge port 104, and the upper end of the blanking plate 6 is connected to the side wall of the frame 101.

[0052] When the discharge port 104 is opened for discharge, the soil can fall with the inclined drop plate 6, reducing the amount of soil remaining in the disposal bin 1 after discharge, allowing the dehydrated soil in the disposal bin 1 to be discharged cleanly, improving the smoothness of discharge, and thus improving the discharge efficiency.

[0053] Furthermore, if Figure 3 As shown, in one embodiment of the present invention, the dehydration injection assembly 2 also includes a second motor 202, the drill rod 201 is rotatably connected to the frame 101, the output shaft of the second motor 202 is fixedly connected to the drill rod 201, and the second motor 202 drives the drill rod 201 to rotate; the contaminated soil disposal mixing equipment also includes a lifting assembly 7, the lifting assembly 7 includes a support frame 701, a third motor 702, a screw 703 and a sleeve 704, the support frame 701 is fixedly connected to the upper surface of the top wall 1011, the third motor 702 is arranged on the support frame 701, the screw 703 is connected to the output shaft of the third motor 702, the third motor 702 drives the screw 703 to rotate, the screw 703 is vertically arranged, the screw 703 is threadedly connected to the sleeve 704, and the sleeve 704 is fixedly connected to one side of the second motor 202.

[0054] The second motor 202 is used to drive the drill rod 201 to rotate, and the drill rod 201 rotates forward or reversely when high-pressure gas is sprayed in the disposal chamber 1, thereby enhancing the dehydration effect. The third motor 702 in the lifting assembly 7 drives the screw rod 703 to rotate, and the screw rod 703 rotates to drive the sleeve 704 to move up and down on the screw rod 703, driving the second motor 202 to move up and down, adjusting the height of the second motor 202, and synchronously adjusting the depth of the drill rod 201 descending in the disposal chamber 1, so that the drill rod 201 covers a larger working range.

[0055] To further illustrate, the rotating seat 301 and the drill rod 201 rotate in opposite directions, and the guide disc 304 rotates with the rotating seat 301 driven by the wire rope 303. The wire rope 203 and the drill rod 201 are crossed for stirring, so that the flow of the soil is more chaotic, which can improve the uniformity of soil stirring, and enable the drill rod 201 to spray different soils, thereby improving the overall dehydration efficiency of the soil. In addition, the rotating seat 301 and the drill rod 201 can also rotate in the same direction to achieve joint stirring; or when the rotating seat 301 rotates, the drill rod 201 does not rotate, and only the rotating seat 301 rotates forward or reversely to perform separate stirring.

[0056] Furthermore, if Figure 1 As shown, in one embodiment of the present invention, a fixed cover 8 is movably provided outside the disposal chamber 1 , and the fixed cover 8 is used to seal the disposal chamber 1 .

[0057] After the soil enters the disposal bin 1, the water in the soil will gradually seep out from the geotube bags 102 on the surrounding walls. The fixed cover 8 can be mounted outside the disposal bin 1. When the fixed cover 8 completely closes the disposal bin 1, the fixed cover 8 and the disposal bin 1 form a closed space. The water cannot pass through the fixed cover 8, and the water will accumulate in the disposal bin 1. In the soil dehydration process, after the soil enters the disposal bin 1, it is necessary to add flocculants to the disposal bin 1 to improve the dehydration efficiency. After adding the flocculants, in order to make the flocculants evenly distributed in the soil, it is necessary to stir the soil with the stirring component 3, which will accelerate the dehydration of the soil, and the flocculants will be discharged from the disposal bin 1 along with the water. The fixed cover 8 can close the disposal bin 1, and remove the fixed cover 8 after the flocculants are stirred in the soil until they are evenly distributed. After removing the fixed cover 8, the dehydration operation is performed. At the same time, the fixed cover 8 supports and restrains the geotube 102, preventing the undehydrated soil from entering the disposal bin 1 and exerting excessive pressure on the geotube 102, causing the geotube 102 to deform, thereby extending the service life of the geotube 102.

[0058] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
