Description

Technical Field

[0001] The invention relates to the technical field of soil leaching and restoration, and in particular to a coastal soil restoration and improvement device. Background Art

[0002] Coastal wetlands play a key role in conserving fresh water, regulating climate and maintaining biodiversity. With the increase of domestic garbage, it has caused certain damage to the coastal sea area and coastal soil environment. The content of inorganic matter and heavy metal substances in coastal soil exceeds the standard, which seriously affects the growth of vegetation and ecological balance in coastal soil. In this regard, special eluent can be used to spray coastal soil to solve some soil environmental problems, and the salinity of coastal soil can be reduced by spraying and flushing.

[0003] Chinese patent authorization announcement number CN116651915A discloses an apparatus and method for repairing heavy metal contaminated soil by elution combined with oxidation. A cabin is set up as a elution space, and a treatment tank is set up to discharge the waste liquid through a discharge pipe and an extraction pump through a waste liquid pipe after elution. At the same time, the gas generated during the reaction process is introduced into the treatment tank through a connecting pipe for collection to facilitate the reaction. The guide plate is set up to guide the soil, and the branch pipe and the nozzle are installed through a pipe rack.

[0004] The above-mentioned prior art solution has the following shortcomings: in the device, a vibration motor is used in conjunction with an inclined mesh plate to cause the soil to vibrate on the mesh plate to increase the uniform contact between the soil and the eluent. However, due to the inclined setting of the mesh plate and the continuous vibration of the mesh plate in this structure, the soil as a whole passes through the mesh plate for a short time, which makes it difficult for the eluent to fully contact and react with the soil, affecting the repair effect of the eluent. In addition, since the soil in the device is filtered and washed by the mesh plate only once, the treatment effect on impurities and pollutants in the soil is general, so there is room for improvement. Summary of the invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) Through the extension and retraction of the electric telescopic rod, the roller pushes one side of the swing plate back and forth, and cooperates with the elasticity of the spring 1 to realize the reciprocating swing of the swing plate. Under the action of the discharging mechanism, when the swing plate swings downward along the arc-shaped fixed plate, the coastal soil in the soil bucket can directly fall on the swing plate and the arc-shaped fixed plate for separate immersion. Due to the cooperation of the angle adjustment mechanism, the electric telescopic rod synchronously controls the flipping of the nozzle on the elution pipe, so that the elution liquid can be sprayed in the direction of the arc-shaped fixed plate, so that the coastal soil can be immersed in the cavity between the arc-shaped fixed plate and the swing plate and the U-shaped baffle, so as to improve the full reaction between the elution liquid and the soil, thereby improving the full soil repair effect;

[0019] As the swing plate flips along the arc-shaped fixed plate, the roller rubs against the arc-shaped surface of the arc-shaped fixed plate, causing the roller to rotate and reel in the pull rope. With the help of the guiding effect of the guide plate, the rolling ball hits the top surface of the swing plate from the inside to promote the vibration effect of the soil on the surface of the swing plate. When the swing plate flips downward, the vibration effect further promotes the full contact reaction between the soil and the elution liquid. When the swing plate flips upward, with the elasticity of the spring three, the swing plate vibrates continuously and promotes the transfer of soil to the vibration mesh plate to reduce the adhesion of soil on the surface of the swing plate.

[0020] Due to the action of the roller, a certain gap is generated between the two ends of the swing plate and the arc-shaped fixed plate. The gap is used to make the eluent flow slowly along the through hole during the soaking process, so that the eluent can discharge the heavy metal impurities in the soil, so as to achieve the initial repair effect of the soil.

[0021] (2) Through the cooperation of the vibrating mesh plate and the upper and lower vibrating mechanisms, the rotation of the cam realizes the up and down reciprocating movement of the rectangular frame, thereby realizing the continuous vibration of the vibrating mesh plate. By utilizing the structure of the vibrating mesh plate, the soil can be sprayed and washed again under the rolling of the surface of the vibrating mesh plate, thereby further improving the repair effect of coastal soil;

[0022] At the same time, the upper and lower vibration mechanisms simultaneously realize the vibration of the collection box, so that the soil mud falling inside the collection box after elution can produce vibration, and then with the help of the detachable filter, the mud is filtered again, so that the solid impurities are retained in the collection box for recycling, and the liquid can be recycled through the water treatment tank and circulated to the elution pipe for spraying again;

[0023] The function of the triangular guide block and the intercepting convex strip is to facilitate the preliminary treatment of the eluent falling on the triangular guide block. The special structure of the intercepting convex strip allows smaller solid impurities to be retained in the protrusions or grooves, thereby further improving the recovery of solid impurities and the pretreatment effect of liquid impurity removal.

[0039] A vibration immersion mechanism is provided inside the side of the swing plate 13 close to the arc-shaped fixed plate 12, and the vibration immersion mechanism includes a knocking assembly 32 and a reciprocating pulling assembly 33 provided inside the knocking assembly 32, the knocking assembly 32 includes a cavity 3201 opened on the side of the swing plate 13 close to the arc-shaped fixed plate 12, and four guide plates 3204 are installed at equal intervals at the bottom end of the cavity 3201, and the cross-section of the guide plate 3204 is triangular, and the two inclined surfaces of the triangle are arc-shaped surfaces, and a movable rod 3202 is movably installed on the side of the cavity 3201 close to the rotation center of the swing plate 13, and Rolling balls 3203 are sleeved at equal intervals on the outside of the movable rod 3202, and pull ropes 3302 are installed at both ends of the movable rod 3202. A roller 3301 is installed on the side of the cavity 3201 close to the arc-shaped fixed plate 12, and the outer wall of the roller 3301 is against the arc-shaped surface of the arc-shaped fixed plate 12.

[0040] The first support plates 4 are installed on the two opposite outer side walls of the U-shaped baffle plate 2, and the top ends of the inner walls of the two first support plates 4 are connected with soil buckets 5, which are located just above the arc-shaped fixed plate 12. A discharge mechanism 30 is provided at the bottom end of the soil bucket 5, and one side of the discharge mechanism 30 is connected to one side of the top end of the horizontal sliding plate 26, so that when the swing plate 13 is turned downward along the arc-shaped fixed plate 12, the soil falls from the bottom opening of the soil bucket 5 onto the arc-shaped fixed plate 12 and the swing plate 13;

[0041] The discharging mechanism 30 includes a discharging plate 3001 slidably mounted on the bottom of the soil bucket 5, and L-shaped connecting rods 3003 are mounted on both sides of the bottom of the discharging plate 3001, and L-shaped movable plates 3002 are mounted on both sides of the top of the horizontal sliding plate 26, and one side of the top of the two L-shaped movable plates 3002 extends to the bottom of the discharging plate 3001, and one end of the L-shaped movable plate 3002 is opened with a sliding hole 3004, and one end of the L-shaped connecting rod 3003 extends to the inside of the sliding hole 3004;

[0042] Second support plates 6 are installed on both outer walls of the U-shaped baffle plate 2, and a leaching pipe 7 is penetrated through the top of the inner wall of the two second support plates 6, and one end of the leaching pipe 7 is rotatably connected to a three-way pipe 8, a water treatment box 10 is installed on one side of the support platform 1, and a circulation pipe 9 is connected to one end of the three-way pipe 8 on one side of the top of the water treatment box 10, and the other end of the three-way pipe 8 is connected to an external leaching liquid supply device, and the bottom end of one side of the water treatment box 10 is connected to one side of the collection cabinet 3 through a connecting pipe 22, and a plurality of nozzles are arranged on the side wall of the leaching pipe 7 at equal intervals, and both ends of the leaching pipe 7 are connected to one side of the discharging mechanism 30 through an angle adjustment mechanism 31 to realize the rotation of the nozzle on the leaching pipe 7, so that the leaching liquid sequentially leaches the soil on the arc-shaped fixed plate 12 and the vibration mesh plate 11;

[0043] The angle adjustment mechanism 31 includes a gear ring 3103 sleeved on one end of the elution tube 7, and a gear plate 3102 is slidably installed on the inner wall of the U-shaped baffle 2 below the gear ring 3103, and the top of the gear plate 3102 is meshed with the outer side of the gear ring 3103, and a linkage plate 3101 is installed at one end of the gear plate 3102, and one end of the linkage plate 3101 is connected to one end of the L-shaped movable plate 3002 close to the sliding hole 3004. The left and right horizontal movement of the gear plate 3102 causes the gear ring 3103 to rotate left and right within a range of 70°.

[0044] In this embodiment, when in use, the soil from the coastal area is placed inside the soil bucket 5, and the electric telescopic rod 25 is started to shorten, so that the horizontal sliding plate 26 moves left again with the roller 27, so that one side of the swing plate 13 is turned down along the surface of the arc-shaped fixed plate 12 under the pull of its own weight and the elasticity of the spring 23. In this process, the L-shaped movable plate 3002 moves left synchronously, so that the L-shaped connecting rod 3003 slides along the sliding hole 3004, and moves left synchronously with the L-shaped movable plate 3002, so that the discharge plate 3001 is opened to allow the soil to fall between the swing plate 13 and the arc-shaped fixed plate 12 and the U-shaped baffle 2. At the same time, as the tooth plate 3102 moves left, the nozzle on the elution pipe 7 rotates, so that the elution liquid is directed to the arc-shaped fixed plate 12, so that the soil is infiltrated under the elution liquid. At the same time, part of the infiltration liquid removes impurities in the soil along the gap between the swing plate 13 and the arc-shaped fixed plate 12, and falls into the interior of the collection cabinet 3 along the through hole 28. During the rotation of the movable plate 13 along the arc-shaped fixed plate 12, the roller 3301 always rubs against the surface of the arc-shaped fixed plate 12. When the roller 3301 reels the pull rope 3302, the ball 3203 approaches the roller 3301 along the guide plate 3204. At the same time, due to the special structure of the guide plate 3204, the ball 3203 hits the top surface of the swing plate 13 from the inside to promote the vibration of the soil on the swing plate 13, on the one hand, to increase the full contact reaction between the soil and the eluent. When the electric telescopic rod 25 is extended and reset, the swing plate 13 is reset upward and the soil is transferred to the vibration mesh plate 11. In this process, due to the reverse friction rotation of the roller 3301 and the arc-shaped fixed plate 12, and under the elastic pull of the spring three 3303, the movable rod 3202 continues to knock on the top surface of the swing plate 13, thereby further promoting the sliding transfer of the soil to the vibration mesh plate 11, so as to avoid the adhesion and residue of coastal soil on the swing plate 13.

[0045] Embodiment 2

[0046] This embodiment is different from the first embodiment. The upper and lower vibration mechanisms 34 are used to achieve synchronous vibration of the vibration screen 11 and the collection box 18. On the one hand, the vibration screen 11 is used to separate the soil from the eluent. On the other hand, the separation of impurities in the eluent from the water body is promoted, so as to achieve water circulation and sufficient soil restoration and purification. Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 As shown:

[0047] A mounting groove 15 is provided on one side of the bottom end of the collection cabinet 3, and telescopic sleeves 16 are evenly installed inside the mounting groove 15, and the top ends of the multiple telescopic sleeves 16 are connected to a collection box 18, and the collection box 18 is located directly below the second through hole 29, and a detachable filter screen 19 is installed at the bottom end of one side of the collection box 18, and an up-and-down vibration mechanism 34 is provided inside the support platform 1 to drive the vibration screen plate 11 and the collection box 18 to vibrate up and down respectively;

[0048] The up-and-down vibration mechanism 34 includes a motor 3401 installed inside the support platform 1, and a cam 3402 is installed at the output end of the motor 3401, a rectangular frame 3403 is sleeved on the outside of the cam 3402, the inner top surface of the rectangular frame 3403 is against the top surface of the cam 3402, an upper push rod 3404 is installed at the top of the rectangular frame 3403, and the top of the upper push rod 3404 is against one side of the bottom end of the vibration mesh plate 11, a lower push rod 3405 is installed at the bottom end of the rectangular frame 3403, and a push block 3406 is installed on one side of the collection box 18 below the lower push rod 3405;

[0049] The width of the rectangular frame 3403 matches the diameter of the cam 3402, and the rectangular frame 3403 and the support platform 1 form an up-and-down sliding connection. Under the rotation of the cam 3402, the rectangular frame 3403 produces an up-and-down reciprocating movement;

[0050] A triangular guide block 20 is installed on the side of the bottom of the collecting cabinet 3 away from the collecting box 18, and the triangular guide block 20 is located below the detachable filter screen 19. The top surface of the triangular guide block 20 is inclined, and the height of the top surface of the triangular guide block 20 away from the collecting box 18 is lower. The top of the triangular guide block 20 is evenly installed with intercepting convex strips 21;

[0051] There are five intercepting ridges 21 , and the intercepting ridges 21 are evenly spaced on the triangular guide block 20 . The top end surface of the intercepting ridge 21 has an arc-shaped cross section, and an arc-shaped groove is provided on the top end surface.

[0052] In this embodiment, when the soil moves onto the vibrating mesh plate 11, the filter hole structure of the vibrating mesh plate 11 is used in conjunction with the elution effect of the nozzle on the elution pipe 7, so that the impurities in the soil can be further eluted and transferred to the collection box 18, thereby improving the soil repair effect. At the same time, the motor 3401 is started to rotate the cam 3402, so that it drives the rectangular frame 3403 to move up and down reciprocatingly, so that the upper push rod 3404 hits one end of the vibrating mesh plate 11, so that the soil on the vibrating mesh plate 11 vibrates and rolls down, and on the other hand, the elution liquid and impurities falling into the collection box 18 are vibrated, so as to improve the soil repair effect. It promotes further cleaning and separation between impurities and the elution liquid, and under the action of the detachable filter 19, the solid impurities are retained in the collection box 18, and part of the water moves along the triangular guide block 20 to the water treatment box 10, wherein the fine impurities remaining in the water are intercepted under the special structure of the interception ridge 21. When the water enters the water treatment box 10, it enters the circulation pipe 9 after treatment and circulates to the elution pipe 7 for elution use, thereby reducing the waste of water flow. At the same time, the collection cabinet 3 is opened to facilitate the separate recovery and treatment of the solid impurities separated from the soil.
