Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a soil remediation agent spraying device with a quick-change nozzle. Background Technology

[0002] Soil remediation utilizes physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in soil, reducing their concentration to acceptable levels and restoring the soil to its normal function. Soil remediation typically involves incorporating remediation solutions and pollutant-decomposing microorganisms into the soil to degrade and dilute internal pollutants, hindering their spread. This requires a spraying device to apply the remediation solution. However, existing soil remediation spraying devices often suffer from problems. Since soil remediation agents are generally solid, they easily clump together during prolonged storage, leading to incomplete mixing and dissolution, resulting in unsatisfactory spraying effects. Furthermore, the remediation agent may settle at the bottom, affecting its effectiveness. Additionally, impurities may exist within the mixing tank, clogging the nozzles, reducing efficiency, and making nozzle replacement inconvenient. Overall, these methods are quite cumbersome.

Detailed Implementation

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

[0025] Please see Figure 1-5 This utility model provides a technical solution: a soil remediation agent spraying device with a quick-change nozzle, including a chassis 1, casters 2, handle 3, mixing box 4, rotating shaft 1 5, motor 6, mixing fan 1 7, scraper 8, cleaning brush 9, belt 10, feed box 11, rotating shaft 2 12, mixing fan 2 13, screen 14, water inlet pipe 15, filter screen 16, water pump 17, water outlet pipe 18, sealing ring 19, nozzle 20 and sleeve 21;

[0026] This soil remediation agent spraying device can dissolve the soil remediation agent. The specific implementation method is as follows:

[0027] A caster wheel 2 is installed at the bottom of the chassis 1, and a handle 3 is fixedly connected to one side of the chassis 1. A mixing tank 4 is fixedly connected to the surface of the chassis 1, and a rotating shaft 5 is rotatably installed inside the mixing tank 4. A motor 6 is connected to the surface of the mixing tank 4, and one side of the rotating shaft 5 passes through the mixing tank 4 and is connected to the output shaft of the motor 6. A stirring fan 7 and a scraper 8 are sleeved on the surface of the rotating shaft 5 and are located inside the mixing tank 4. A cleaning brush 9 is fixedly connected to the surface of the scraper 8. A belt 10 is sleeved on the surface of the rotating shaft 5 and is located on the outside of the mixing tank 4. The surface of the feed box 11 is embedded in the feed box 11, and the feed box 11 is rotatably mounted with a second rotating shaft 12. The surface of the second rotating shaft 12 is fitted with a second stirring fan 13, and the second rotating shaft 12 passes through the outside of the feed box 11 and is fitted with a belt 10. The inner wall of the feed box 11 is fixedly connected with a net 14. The first rotating shaft 5 is rotatably connected to the mixing box 4. The bottom of the scraper 8 is in contact with the bottom surface of the mixing box 4. The second rotating shaft 12 is rotatably connected to the feed box 11, and the feed box 11 is rotatably connected to the second stirring fan 13. The bottom of the second stirring fan 13 is in contact with the surface of the net 14, and the second stirring fan 13 is rotatably connected to the net 14.

[0028] The soil remediation agent is poured into the feed hopper 11 and falls onto the surface of the mesh screen 14. At this time, motor 6 is started, driving rotating shaft 5 to rotate. Rotating shaft 5 rotates inside the feed hopper 11 via rotating shaft 12, which in turn drives stirring fan 13 to rotate on the surface of the mesh screen 14. Water and reagents are then added from the feed hopper 11. The water and reagents carry smaller volumes of soil remediation agent through the holes in the mesh screen 14, falling into the mixing tank 4, ensuring thorough contact between the water and reagents and the soil remediation agent, and stirring. Fan 2 13 moves the soil remediation agent on the surface of the screen 14, causing it to collide with each other inside the feed box 11, reducing its volume. The agent then falls into the mixing box 4 through the holes in the screen 14. Motor 6 drives rotating shaft 1 5 to rotate, which in turn drives stirring fan 1 7 to rotate. Stirring fan 1 7 stirs the soil remediation agent, water, and reagents that have entered the mixing box, ensuring they are fully mixed. Rotating shaft 1 5 drives scraper 8 to rotate, which stirs the solution at the bottom of the mixing box 4 to prevent the soil remediation agent from settling.

[0029] The soil remediation agent spraying device allows for the replacement of the nozzle 20. The specific implementation method is as follows:

[0030] The inner wall of the mixing tank 4 is provided with a water inlet pipe 15, and a filter screen 16 is provided at the end of the water inlet pipe 15. A water pump 17 is installed on the surface of the mixing tank 4, and the other end of the water inlet pipe 15 passes through the mixing tank 4 and is connected to the water pump 17. A water outlet pipe 18 is connected to the surface of the water pump 17. A sealing ring 19 is embedded in the end of the water outlet pipe 18, and a nozzle 20 is fixedly connected to the end of the sealing ring 19. A sleeve 21 is fitted on the surface of the end of the water outlet pipe 18. The surface of the water outlet pipe 18 is provided with threads, and the water outlet pipe 18 and the sleeve 21 are threadedly connected. The sleeve 21 and the sealing ring 19 are slidably connected, and the sleeve 21 is fitted on the surface of the sealing ring 19. The sealing ring 19 and the water outlet pipe 18 are slidably connected, and the sleeve 21 is fitted on the surface of the sealing ring 19. The cleaning brush 9 is positioned correspondingly to the filter screen 16, and the filter screen 16 and the cleaning brush 9 are slidably connected.

[0031] The water pump 17 is started, and it absorbs the mixed solution from the mixing tank 4 through the inlet pipe 15. The filter screen 16 filters the solution entering the inlet pipe 15 to prevent particulate matter from entering and clogging the nozzle 20. As the scraper 8 rotates, it drives the cleaning brush 9 to rotate. When the cleaning brush 9 rotates to one side of the filter screen 16, it cleans the surface of the filter screen 16 to prevent clogging. The filtered solution enters the outlet pipe 18 through the water pump 17 and is finally sprayed out through the nozzle 20 onto the soil surface. When the nozzle 20 needs to be replaced, the sleeve 21 is rotated. 1. Move downwards along the threads on the surface of the water outlet pipe 18. At this time, the sleeve 21 moves downwards on the surface of the sealing ring 19, so that the sleeve 21 moves off the surface of the sealing ring 19. Then, remove the end of the sealing ring 19 from the inside of the water outlet pipe 18. The sealing ring 19 drives the nozzle 20 to be removed. Then, insert the new sealing ring 19 into the inside of the water outlet pipe 18. Install the nozzle 20 at the end of the water outlet pipe 18. Rotate the sleeve 21 in the opposite direction. The sleeve 21 moves upwards along the threads on the surface of the water outlet pipe 18, so that the sleeve 21 moves to the surface of the sealing ring 19, restricting the position of the sealing ring 19. At this time, install the nozzle 20 at the end of the water outlet pipe 18.

[0032] Working principle: When using this soil remediation agent spraying device with quick-change nozzles, a mixing fan 2 13 and a screen 14 are set up to dissolve the soil remediation agent, and a sleeve 21 and a sealing ring 19 are set up to replace the nozzles, which increases the overall practicality.
