Description

Technical Field

[0001] The present invention relates to the technical field of environmental governance, and in particular to a soil remediation system for environmental governance. Background Art

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. When managing the environment, physical, chemical and biological methods are generally used 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. At present, when remediating contaminated soil, the soil is mixed with a remediation agent to achieve the remediation effect.

[0003] After searching, the Chinese patent "A soil remediation device for environmental management" authorization announcement number "CN 216779836 U" is provided with a second servo motor. When the second servo motor works, the output shaft of the second servo motor can drive the rotating shaft to rotate, thereby driving a plurality of stirring rods to rotate, and then driving the stirring rods to mix the soil to be repaired and the repair liquid evenly.

[0004] In the above application, the soil and the repair liquid can be mixed. Since the soil itself has a certain viscosity, part of the soil will adhere to the inner wall of the repair box during the mixing and stirring process with the repair agent, which will cause insufficient mixing of the soil and the repair agent, thereby affecting the soil repair effect.

[0005] Therefore, a soil remediation system for environmental management is proposed to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a soil remediation system for environmental management in order to solve the above-mentioned problems, thereby improving the problem that due to the certain viscosity of the soil itself, part of the soil will adhere to the inner wall of the remediation box during the mixing and stirring process with the remediation agent, resulting in insufficient mixing of the soil and the remediation agent, thereby affecting the soil remediation effect.

[0007] The present invention achieves the above-mentioned purpose through the following technical scheme. A soil remediation system for environmental governance includes: a mounting frame, a mixing barrel is installed on the top of the mounting frame, and a stirring mechanism is arranged inside the mixing barrel; wherein the stirring mechanism includes a stirring rod rotatably connected to the inner wall of the mixing barrel, one end of the mixing barrel is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a first bevel gear, the surface of the first bevel gear is meshedly connected to two second bevel gears, one end of the stirring rod sequentially passes through the mixing barrel and one of the second bevel gears and is fixedly connected to one end of the other second bevel gear, the surface of the stirring rod is rotatably connected to a swivel, one end of the swivel passes through the mixing barrel and is fixedly connected to one end of one of the second bevel gears, the surface of the swivel is fixedly connected to two connecting rods, and the other end of the connecting rod is fixedly connected to a scraper.

[0008] Preferably, the stirring mechanism further comprises a mounting rod rotatably connected to the inner wall of the connecting rod, the surface of the mounting rod is fixedly connected to round rods distributed in equal rows, one end of the mounting rod passes through the connecting rod and is fixedly connected to a first gear, one end of the inner wall of the mixing barrel is fixedly connected to a gear ring, and the first gear is meshingly connected to the gear ring. When the scraper rotates to scrape and move the soil on the inner wall and edge of the mixing barrel, the interaction between the first gear and the gear ring facilitates the connecting rod to drive the mounting rod to rotate, and the mounting rod drives the round rod to rotate during the rotation process. The rotation of the round rod facilitates the stirring of the soil inside the scraper, thereby improving the stirring effect on the soil.

[0009] Preferably, a protective plate is fixedly connected to the surface of the rotating ring, the surface of the mounting rod is rotatably connected to the inner wall of the protective plate, and the surface of the protective plate is in contact with the inner wall of the mixing barrel, which is beneficial for protecting the first gear and the gear ring and ensuring the normal operation of the device.

[0010] Preferably, a cleaning rod is fixedly connected to the lower end of the surface of the mounting rod, and both sides of the cleaning rod form an angle with the vertical plane, which is conducive to scraping off the soil adhering to the inner surface of the scraper, which is conducive to fully mixing the soil, and at the same time improves the scraper's effect of scraping off the sticky soil on the inner wall of the mixing barrel.

[0011] Preferably, the surface of the scraper is curved in an arc shape, and the other end of the cleaning rod is in contact with the inner surface of the scraper. By setting the surface of the scraper to be arc-shaped, the scraper can be better used to move the soil on the edge of the mixing barrel. At the same time, under the action of the arc surface of the scraper and the cleaning rod, the cleaning effect of the cleaning rod on the inner surface of the scraper can be improved.

[0012] Preferably, one end of the scraper is fixedly connected to a mounting plate, and the vertical cross section of the mounting plate is a right triangle, thereby improving the scraper's effect of scraping away soil adhering to the inner wall of the mixing barrel.

[0013] Preferably, the surface of the protective plate is provided with an annular groove, and the inner wall of the annular groove is rotatably connected with circular rollers distributed in an annular shape, which is beneficial to reduce the contact area between the surface of the protective plate and the inner wall of the mixing barrel, and reduce the friction between the protective plate and the inner wall of the mixing barrel when rotating.

[0014] The beneficial effects of the present invention are:

[0015] 1. The setting of the stirring mechanism, the starting motor drives the two second bevel gears to rotate synchronously through the first bevel gear, so that the stirring rod rotates to stir the soil while the scraper rotates synchronously to scrape the soil adhering to the inner wall of the mixing barrel, which is conducive to fully stirring and mixing the soil in the mixing barrel with the repair agent. When the scraper rotates, under the action of the scraper arc surface, it is conducive to moving the soil at the edge of the mixing barrel to the center of the mixing barrel, which is conducive to making the soil at the edge of the inner wall of the mixing barrel fully contact with the stirring rod and stir, thereby improving the stirring effect of the soil, and under the action of the two second bevel gears, the scraper and the stirring rod rotate in opposite directions, so that the direction of the scraper moving the soil is opposite to the stirring direction of the stirring rod, which increases the force of the stirring rod when stirring the edge soil, which is conducive to fully mixing the soil in the mixing barrel with the repair agent, thereby improving the repair effect of the soil;

[0016] 2. When the scraper rotates to scrape and move the soil on the inner wall and edge of the mixing barrel, the interaction between the first gear and the gear ring is conducive to the connection rod driving the mounting rod to rotate, and the mounting rod drives the round rod to rotate. The rotation of the round rod is conducive to stirring the soil inside the scraper, thereby improving the stirring effect of the soil;

[0017] 3. By setting up the cleaning rod, it is helpful to scrape off the soil adhering to the inner surface of the scraper, which is conducive to fully mixing the soil, and at the same time improves the scraper's effect of scraping off the sticky soil on the inner wall of the mixing barrel.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] When implementing: Figure 1-5 As shown, a soil remediation system for environmental management comprises: a mounting frame 1, a mixing barrel 2 is mounted on the top of the mounting frame 1, and a stirring mechanism 3 is arranged inside the mixing barrel 2; wherein the stirring mechanism 3 comprises a stirring rod 31 rotatably connected to the inner wall of the mixing barrel 2, one end of the mixing barrel 2 is fixedly connected to a motor 32, an output shaft of the motor 32 is fixedly connected to a first bevel gear 33, two second bevel gears 34 are meshingly connected to the surface of the first bevel gear 33, one end of the stirring rod 31 passes through the mixing barrel 2 and one of the second bevel gears 34 in sequence and is fixedly connected to one end of the other second bevel gear 34, a swivel 35 is rotatably connected to the surface of the stirring rod 31, one end of the swivel 35 passes through the mixing barrel 2 and is fixedly connected to one end of one of the second bevel gears 34, two connecting rods 36 are fixedly connected to the surface of the swivel 35, and a scraper 37 is fixedly connected to the other end of the connecting rod 36.

[0026] A feed port is provided at the upper end of the surface of the mixing barrel 2. When the soil is remediated, the contaminated soil and the remediation agent are poured into the mixing barrel 2 from the feed port. A discharge port is provided at the lower end of the surface of the mixing barrel 2, and a sealing cover is provided at the outlet end of the discharge port. During the stirring process of the soil, the sealing cover seals the discharge port. After the stirring is completed, the sealing cover can be used to discharge the soil.

[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the stirring mechanism 3 also includes a mounting rod 38 rotatably connected to the inner wall of the connecting rod 36, and the surface of the mounting rod 38 is fixedly connected with round rods 39 distributed in equal rows, one end of the mounting rod 38 passes through the connecting rod 36 and is fixedly connected with a first gear 310, and one end of the inner wall of the mixing barrel 2 is fixedly connected with a gear ring 311, and the first gear 310 is meshingly connected with the gear ring 311.

[0028] When the contaminated soil and the repair agent are poured into the mixing barrel 2, the motor 32 is started by the controller, so that the output shaft of the motor 32 drives the first bevel gear 33 to rotate counterclockwise, and under the action of the first bevel gear 33, the two second bevel gears 34 are driven to rotate synchronously, and the rotation directions are opposite. One of the second bevel gears 34 drives the rotating ring 35 to rotate clockwise, and the other second bevel gear 34 drives the stirring rod 31 to rotate counterclockwise to stir the soil in the mixing barrel 2. When the rotating ring 35 rotates, the corresponding scraper 37 is driven to rotate clockwise synchronously through the two connecting rods 36. The two scrapers 37 are symmetrical with the center of the stirring rod 31. When the scraper 37 rotates, the scraper 37 will scrape the soil adhered to the inner wall of the mixing barrel 2 The soil is scraped off by the scraper 37. At the same time, the scraper 37 will push the soil on the edge of the mixing barrel 2 toward the center of the mixing barrel 2 during the rotation process, and the pushing direction of the soil is opposite to the stirring direction of the stirring rod 31, which will increase the force of the stirring rod 31 on the edge soil. At the same time, the connecting rod 36 drives the scraper 37 to rotate and drives the mounting rod 38 to rotate synchronously, so that the mounting rod 38 rotates with the stirring rod 31 as the center of the circle. At this time, under the action of the first gear 310 and the ring gear 311, the mounting rod 38 will be driven to rotate, so that the mounting rod 38 drives the round rod 39 to rotate to stir the soil inside the scraper 37. Two groups of round rods 39 are provided, and the two groups of round rods 39 are symmetrical about the center of the circle of the mounting rod 38.

[0029] like Figure 2 and Figure 5 As shown, the surface of the rotating ring 35 is fixedly connected with the protective plate 312, the surface of the mounting rod 38 is rotatably connected with the inner wall of the protective plate 312, and the surface of the protective plate 312 is in contact with the inner wall of the mixing barrel 2. An annular groove 315 is provided on the surface of the protective plate 312, and the inner wall of the annular groove 315 is rotatably connected with circular rollers 316 distributed in an annular shape. When the surface of the protective plate 312 is in contact with the inner wall of the mixing barrel 2, the surface of the circular roller 316 is in contact with the inner wall of the mixing barrel 2, and the surface of the mounting rod 38 is rotatably connected with the inner wall of the protective plate 312. When the rotating ring 35 rotates, the protective plate 312 is driven to rotate synchronously, and the circular roller 316 is caused to rotate.

[0030] like Figure 3 and Figure 4 As shown, the lower end of the surface of the mounting rod 38 is fixedly connected to a cleaning rod 313, and both sides of the cleaning rod 313 form an angle with the vertical plane. The surface of the scraper 37 is curved in an arc shape, and the other end of the cleaning rod 313 is in contact with the inner surface of the scraper 37. The center of the scraper 37 coincides with the center of the mounting rod 38, so when the mounting rod 38 drives the cleaning rod 313 to rotate, it will rotate in contact with the inner surface of the scraper 37, and when the mounting rod 38 rotates, it will drive the cleaning rod 313 to rotate synchronously, and when the cleaning rod 313 rotates, it will scrape off the soil adhered to the inner surface of the scraper 37.

[0031] like Figure 4 As shown, one end of the scraper 37 is fixedly connected to a mounting plate 314, and the vertical section of the mounting plate 314 is a right triangle. The end of the mounting plate 314 is in contact with the inner wall of the mixing barrel 2, and when the scraper 37 rotates, the mounting plate 314 will be driven to rotate synchronously.

[0032] When the present invention is used for soil remediation, the contaminated soil and the remediation agent are poured into the mixing barrel 2 from the feed port, and the motor 32 is started by the controller, so that the output shaft of the motor 32 drives the first bevel gear 33 to rotate counterclockwise, and drives the two second bevel gears 34 to rotate synchronously, so that one of the second bevel gears 34 drives the rotating ring 35 to rotate clockwise, and the other second bevel gear 34 drives the stirring rod 31 to rotate counterclockwise to stir the soil in the mixing barrel 2. When the rotating ring 35 rotates, the corresponding scraper 37 is driven by the two connecting rods 36 to rotate synchronously with the mounting plate 314 clockwise to scrape off the soil adhered to the inner wall of the mixing barrel 2. At the same time, the scraper 37 will mix the soil in the mixing barrel 2 during the rotation process. The soil at the edge of the mixing barrel 2 is pushed toward the center of the mixing barrel 2, and the pushing direction of the soil is opposite to the stirring direction of the stirring rod 31, which will increase the force of the stirring rod 31 on the edge soil. At the same time, the connecting rod 36 drives the scraper 37 to rotate and drives the mounting rod 38 to rotate synchronously. At this time, under the action of the first gear 310 and the ring gear 311, the mounting rod 38 will be driven to rotate, so that the mounting rod 38 drives the round rod 39 to rotate and stir the soil inside the scraper 37. At the same time, the mounting rod 38 will drive the cleaning rod 313 to rotate synchronously so that the cleaning rod 313 can scrape the soil adhered to the inner surface of the scraper 37, so that the soil in the mixing barrel 2 is fully mixed with the repair agent.

[0033] It should be noted that the motor 32 in the above description is a device with relatively mature application of existing technology. The specific model can be selected according to actual needs. At the same time, the motor 32 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
