Description

Technical Field

[0001] This invention relates to the field of soil remediation, and more particularly to a soil crushing, dosing and mixing device for soil remediation. Background Technology

[0002] Soil remediation refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. With the rapid development of industrialization, urbanization, and intensive agriculture, large amounts of untreated waste are transferred to the soil system and, under the influence of natural factors, accumulate and remain in the soil environment, making the current soil environmental quality worrying. Therefore, it is urgent to increase efforts in soil remediation.

[0003] For soils with mild heavy metal pollution, chemical amendments can be sprayed to convert heavy metal ions in the soil into insoluble substances, thereby reducing their concentration in the soil and minimizing harm to plants. However, current soil remediation devices generally mix the soil and chemical amendments directly when spraying them. But because some soil clumps are large and not completely broken up, the soil within the clumps does not come into contact with the chemical amendments, so they cannot be fully mixed, resulting in unsatisfactory soil remediation effects. Summary of the Invention

[0004] In view of this, the present invention provides a soil crushing and chemical mixing device for soil remediation, which can more fully and uniformly mix soil and chemical amendments, more effectively reduce the concentration of heavy metal ions in the soil, and thus more effectively improve the efficiency of soil remediation.

[0005] The technical solution is: a soil crushing, dosing and mixing device for soil remediation, comprising support legs, a working box, a feed hopper, a crushing mechanism and a mixing mechanism. The working box is fixedly connected between the tops of the two support legs. A cleaning door is provided on one side of the working box. Several discharge pipes are provided at the bottom of the working box. The feed hopper is fixedly connected to the top of the working box and communicates with the working box. The crushing mechanism and the mixing mechanism are provided on the working box.

[0006] Furthermore, the crushing mechanism includes a support frame, a dual-shaft motor, a rotating shaft, an extrusion frame, a rotating cam, stirring rods, and a worm gear. The support frame is fixedly connected to the bottom of the working box, and the dual-shaft motor is fixedly connected to the support frame. The rotating shaft is fixedly connected to the output shaft above the dual-shaft motor. The rotating shaft is rotatably connected to the working box. The extrusion frame is slidably connected to the rotating shaft and is located inside the feed hopper. The rotating cam is fixedly connected inside the working box. The upper surface of the rotating cam is provided with several protrusions, and the rotating shaft is rotatably connected to the rotating cam. Several stirring rods are fixedly connected to the rotating shaft, and a worm gear is fixedly connected to the rotating shaft.

[0007] Furthermore, the mixing mechanism includes a spray pipe, a delivery pipe, a rotating shaft, and a worm gear. The spray pipe is fixedly connected to the upper part of the inner wall of the working box, and the delivery pipe is fixedly connected to the working box. The delivery pipe communicates with the spray pipe. Two rotating shafts are rotatably connected to the working box. Each rotating shaft is provided with several short rods. A worm gear is fixedly connected in the middle of each rotating shaft. The worm is located between the two worm gears and meshes with the two worm gears.

[0008] Furthermore, the medicine tube is equipped with several spray nozzles.

[0009] Furthermore, it also includes a stirring mechanism. The working box is equipped with a stirring mechanism, which includes a guide rod, a support rod, a stirring plate, gears, and racks. Two guide rods are fixedly connected to the working box, and two support rods are slidably connected to each guide rod. Each support rod is threadedly connected to a rotating shaft. A stirring plate is rotatably connected between the two support rods. Gears are fixedly connected to both ends of each stirring plate. Two racks are fixedly connected to the inner wall of the working box, and each gear meshes with a rack.

[0010] Furthermore, it also includes an anti-blocking mechanism. The working box is equipped with an anti-blocking mechanism, which includes a sliding frame and a rotating disk. The sliding frame is slidably connected between several discharge pipes of the working box. The rotating disk is fixedly connected to the output shaft below the dual-axis motor. The rotating disk is equipped with a short rod, and the short rod of the rotating disk is slidably connected to the sliding frame.

[0011] Furthermore, it also includes a diversion tube, a drug inlet tube, and nozzles. The drug delivery tube is fixedly connected to the diversion tube and the drug delivery tube is in communication with the diversion tube. The lower end of the diversion tube is fixedly connected to the drug inlet tube and the diversion tube is in communication with the drug inlet tube. The drug inlet tube is rotatably connected to both rotating shafts and the drug inlet tube is in communication with both rotating shafts. Several nozzles are fixedly connected to several short rods on each of the rotating shafts and the several nozzles are in communication with the rotating shafts.

[0012] Furthermore, it also includes a scraper frame, on which several scraper frames are fixedly connected, and each scraper frame is in contact with the inner wall of the discharge pipe of the working box.

[0013] The beneficial effects of this invention are as follows: 1. This invention uses a rotating and reciprocating pressing frame to crush and disperse the soil, allowing small soil particles to enter the working chamber along the pressing frame. Simultaneously, the rotation of the worm gear causes the rotating shaft to rotate, further crushing the soil. The chemical amendments sprayed from several nozzles of the spraying pipe come into uniform contact with the crushed soil, thereby reducing the concentration of heavy metal ions in the soil and improving the efficiency of soil remediation.

[0014] 2. In this invention, the rotating shaft drives the support rod to move back and forth, causing the stirring plate to move back and forth and stir the soil in the working box. This allows the working box to come into full contact with the chemical amendment. At the same time, the stirring plate will rotate back and forth and stir the soil in the working box more thoroughly, and make the soil in the lower part come into more full contact with the chemical amendment. This results in a more thorough and uniform mixing of the soil and the chemical amendment, further improving the efficiency of soil remediation.

[0015] 3. This invention uses a rotating disc to drive a sliding frame to move back and forth repeatedly. This back-and-forth movement of the sliding frame scrapes away soil from several discharge pipes at the bottom of the working box, preventing soil from clogging these pipes and allowing the mixed soil to be discharged quickly. Simultaneously, the back-and-forth movement of the sliding frame also drives several scraping frames to move back and forth repeatedly, further scraping the inner walls of the discharge pipes on the working box. This more effectively prevents the discharge pipes from becoming blocked, allowing the soil to be discharged more smoothly and thus improving the efficiency of soil remediation.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1: A soil crushing, dosing and mixing device for soil remediation, such as... Figures 1-7 As shown, it includes support legs 1, a working box 2, a feed hopper 3, a crushing mechanism, and a mixing mechanism. The working box 2 is bolted between the tops of the two support legs 1. A cleaning door is provided on one side of the working box 2. Several discharge pipes are provided at the bottom of the working box 2. The feed hopper 3 is bolted to the top of the working box 2 and communicates with the working box 2. The working box 2 is equipped with a crushing mechanism and a mixing mechanism. The crushing mechanism is used to crush the soil, and the mixing mechanism is used to mix the soil.

[0026] The crushing mechanism includes a support frame 41, a dual-shaft motor 42, a rotating shaft 43, an extrusion frame 44, a rotating cam 45, stirring rods 46, and a worm gear 47. The bottom of the working box 2 is bolted to the support frame 41. The dual-shaft motor 42 is bolted to the support frame 41. The output shaft above the dual-shaft motor 42 is bolted to the rotating shaft 43. The rotating shaft 43 is rotatably connected to the working box 2 and is vertically arranged. The extrusion frame 44 is slidably connected to the rotating shaft 43 and is located inside the feed hopper 3. The rotating cam 45 is bolted to the working box 2. The upper surface of the rotating cam 45 is provided with several protrusions, and the rotating shaft 43 is rotatably connected to the rotating cam 45. Several stirring rods 46 are bolted to the rotating shaft 43, and a worm gear 47 is fixedly connected to the rotating shaft 43.

[0027] The mixing mechanism includes a spray pipe 51, a delivery pipe 52, a rotating shaft 53, and a worm gear 54. The spray pipe 51 is fixedly connected to the upper part of the inner wall of the working box 2. The delivery pipe 52 is bolted to the working box 2 and communicates with the spray pipe 51. Two rotating shafts 53 are rotatably connected to the working box 2. Each rotating shaft 53 is provided with several short rods. A worm gear 54 is fixedly connected in the middle of each rotating shaft 53. The worm 47 is located between the two worm gears 54 and meshes with the two worm gears 54.

[0028] The medicine tube is equipped with several spray nozzles.

[0029] The operator first starts the dual-axis motor 42. The output shaft above the dual-axis motor 42 rotates, which drives the rotating shaft 43 to rotate. The rotation of the rotating shaft 43 drives the extrusion frame 44, the worm gear 47, and several agitator rods 46 to rotate together. At the same time, the rotating extrusion frame 44 contacts one of the protrusions on the rotating cam 45. The protrusion pushes the extrusion frame 44 upward. As the extrusion frame 44 continues to rotate, it disengages from the protrusion and moves downward under the influence of gravity. This process repeats, causing the extrusion frame 44 to move up and down during rotation. The rotation of the worm gear 47 drives two worm wheels 54 to rotate, which in turn drives the rotating shaft 53 to rotate. Then, the operator pours the soil with light heavy metal contamination into the feed hopper 3 and simultaneously introduces a chemical amendment into the delivery pipe 52. The chemical amendment in the delivery pipe 52 enters the spray pipe 51 and is then... Several nozzles spray out soil, which first comes into contact with the extrusion frame 44 after being poured in. The extrusion frame 44 rotates and moves up and down to compress the soil, initially dispersing it. Small soil particles enter the working chamber 2 along the extrusion frame 44, while large soil particles are further crushed in the feed hopper 3. After entering the working chamber 2, the small soil particles are first stirred by the stirring rod 46, and then stirred by several short rods on the rotating shaft 53, further dispersing the soil in the working chamber 2. The chemical amendment sprayed from several nozzles of the spray pipe 51 comes into uniform contact with the dispersed soil, thereby reducing the concentration of heavy metal ions in the soil and improving the efficiency of soil treatment. The soil is discharged through several discharge pipes at the bottom of the working chamber 2. After the soil treatment is completed, the staff turns off the dual-shaft motor 42 and opens the cleaning door of the working chamber 2 to clean out the soil remaining in the working chamber 2.

[0030] Example 2: Based on Example 1, such as Figures 3-6 As shown, it also includes a stirring mechanism. The working box 2 is equipped with a stirring mechanism, which includes a guide rod 61, a support rod 62, a stirring plate 63, a gear 64, and a rack 65. Two guide rods 61 are bolted to the working box 2. Two support rods 62 are slidably connected to each guide rod 61. Each support rod 62 is threaded to the rotating shaft 53. A stirring plate 63 is rotatably connected between the two support rods 62. Gears 64 are connected to both ends of each stirring plate 63 by a flat key. Two racks 65 are bolted to the inner wall of the working box 2. Each gear 64 meshes with a rack 65.

[0031] As the rotating shaft 53 rotates, it first drives the two support rods 62 to move closer together. This movement of the support rods 62 causes the stirring plate 63 and gear 64 to move together. The movement of the two stirring plates 63 agitates the soil in the working chamber 2, ensuring full contact between the working chamber 2 and the chemical amendment. Simultaneously, the gear 64 rotates along the rack 65, causing the stirring plate 63 to rotate. This rotation further agitates the soil in the working chamber 2. The continued rotation of the rotating shaft 53 then causes the two support rods 62 to return to their original positions, moving away from each other. When lever 62 resets, it causes agitator 63 and gear 64 to reset together. As gear 64 resets, it reverses along rack 65. The reversal of gear 64 causes agitator 63 to reverse, and this process repeats, causing the two agitator 63 to move back and forth and rotate. This more thoroughly agitates the soil in working box 2, breaking up the soil more completely and continuously turning it over, so that the soil at the bottom can fully contact the chemical amendment. This allows for a more thorough and uniform mixing of the soil and the chemical amendment, further improving the efficiency of soil remediation.

[0032] Example 3: Based on Example 2, such as Figures 1-6 As shown, it also includes an anti-blocking mechanism. The working box 2 is equipped with an anti-blocking mechanism, which includes a sliding frame 71 and a rotating disk 72. The sliding frame 71 is slidably connected between several discharge pipes of the working box 2. The rotating disk 72 is fixedly connected to the output shaft below the dual-axis motor 42. The rotating disk 72 is equipped with a short rod, and the short rod of the rotating disk 72 is slidably connected to the sliding frame 71.

[0033] It also includes a scraper 9, and several scraper 9s are bolted to the sliding frame 71. Each scraper 9 is in contact with the inner wall of the discharge pipe of the working box 2.

[0034] When the dual-axis motor 42 starts, the output shaft below the dual-axis motor 42 rotates, which drives the rotating disk 72 to rotate. The rotation of the rotating disk 72 pushes the sliding frame 71 to move back and forth through the short column. The back and forth movement of the sliding frame 71 scrapes several discharge pipes of the working box 2, thereby preventing soil from clogging the discharge pipes at the bottom of the working box 2, so that the mixed soil can be discharged quickly. At the same time, the back and forth movement of the sliding frame 71 drives several scraping frames 9 to move back and forth. The back and forth movement of the scraping frames 9 scrapes the inner wall of the discharge pipes on the working box 2 more thoroughly and repeatedly, thereby more effectively preventing the discharge pipes of the working box 2 from being blocked, so that the soil can be discharged more smoothly, thereby more effectively improving the efficiency of soil treatment.

[0035] Example 4: Based on Example 3, as shown in Figure X, it further includes a diversion pipe 8, a drug inlet pipe 81, and nozzles 82. The drug delivery pipe 52 is connected to the diversion pipe 8 by bolts, and the drug delivery pipe 52 is connected to the diversion pipe 8. The lower end of the diversion pipe 8 is connected to the drug inlet pipe 81 by bolts, and the diversion pipe 8 is connected to the drug inlet pipe 81. The drug inlet pipe 81 is rotatably connected to both rotating shafts 53, and the drug inlet pipe 81 is connected to both rotating shafts 53. Several nozzles 82 are bolted to several short rods on each rotating shaft 53, and several nozzles 82 are connected to the rotating shaft 53.

[0036] Initially, a portion of the chemical amendment in the delivery tube 52 enters the diversion tube 8, and then flows through the inlet tube 81 and two rotating shafts 53 to several nozzles 82. The nozzles 82 spray the chemical amendment more comprehensively into the surrounding soil. At the same time, the rotation of the rotating shafts 53 drives the nozzles 82 to rotate together, expanding the spraying range of the chemical amendment and thus avoiding the situation where the chemical amendment is not completely sprayed into the soil. This ensures that the soil in the working box 2 is sprayed with the chemical amendment, thereby more effectively reducing heavy metal ions in the soil and improving the soil treatment efficiency.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
