Description

Technical Field

[0001] The invention relates to the technical field of contaminated soil restoration, and in particular to a liquid medicine spraying device for treating soil heavy metal pollution. Background Art

[0002] Heavy metal pollution in soil can destroy the physical, chemical and biological properties of the soil, affect the activity and diversity of soil microorganisms, reduce soil fertility and productivity. Heavy metals can also react with organic and inorganic matter in the soil to form insoluble compounds, reduce the effectiveness of nutrients in the soil, and affect plant growth and development.

[0003] For the restoration treatment of heavy metal contaminated soil, a liquid medicine spraying device can be used to spray the treatment liquid on the heavy metal contaminated soil. The sprayed treatment liquid can form a stable chelate with the heavy metal ions in the soil. The chelating agent molecule has multiple coordinating atoms and can form a ring structure with the heavy metal ions, thereby increasing the stability and solubility of the heavy metal ions. However, in the process of spraying the heavy metal contaminated soil with liquid medicine, due to improper operation and other reasons, excessive treatment liquid may be sprayed on part of the soil and cause them to adhere to each other, resulting in reduced air permeability and poor water permeability of the soil after treatment and restoration, and even the destruction of the soil structure, reducing the effect of restoring the contaminated soil.

[0034] The spray assembly includes a mounting seat 401 arranged outside the drum 1, a mounting tube 402 is fixed on the mounting seat 401, a storage tank 403 for liquid supply is detachably mounted on the upper end of the mounting tube 402 by means of a thread, an L-shaped liquid spraying tube 404 is fixed to the lower end of the mounting tube 402, a plurality of groups of spraying holes 405 are provided on the tube body of the L-shaped liquid spraying tube 404 located inside the drum 1, and a pumping assembly for pumping liquid is provided on the L-shaped liquid spraying tube 404;

[0035] It should be noted here that: in the process of using the liquid medicine spraying device to treat heavy metal contaminated soil, the treatment liquid medicine is sprayed onto the transported soil through the mutual cooperation of the support component, the rotating component and the spraying component to restore the heavy metal contaminated soil. In the process of treatment, through the mutual cooperation of the separation component and the treatment component, the soil that adheres to each other during the spraying treatment process can be separated, and the excess liquid medicine contained in the auxiliary clay soil can be separated under the action of vibration and fall back to the inside of the drum 1 for reuse, thereby reducing the probability of soil adhesion during the liquid medicine spraying treatment and restoration process, and ensuring the effect of restoring the contaminated soil.

[0036] Preferably, the rotating assembly includes a fixing frame 301 fixed to the outside of the mounting sleeve 201, the mounting seat 401 is fixed to the upper end of the fixing frame 301, the fixing frame 301 is rotatably connected with a rotating shaft 302, one end of the rotating shaft 302 is fixed with a gear 303, the outer sleeve of the drum 1 is fixed with a gear ring 304, the gear 303 and the gear ring 304 are meshed with each other, and a driving motor 305 for driving the rotating shaft 302 is installed on the fixing frame 301;

[0037] It should be noted here that: the gear 303 on the rotating shaft 302 is driven to rotate by driving the motor 305. During the rotation of the gear 303, the gear 303 and the gear ring 304 are meshed with each other to drive the roller 1 to move. During the force applied to the roller 1, the annular groove 203 and the annular plate 204 are connected in rotation to make the roller 1 rotate on each group of mounting sleeves 201. Since the roller 1 is arranged in an inclined state, during the rotation of the roller 1, the heavy metal contaminated soil put into the roller 1 is transported toward the inclined side of the roller 1.

[0038] Preferably, the pumping and pressure assembly includes an L-shaped pumping and pressure pipe 501 which is connected and fixed on the L-shaped liquid spraying pipe 404, two sets of one-way valves 502 are fixed inside the L-shaped liquid spraying pipe 404, one end of the L-shaped pumping and pressure pipe 501 is located between the two sets of one-way valves 502, and the two sets of one-way valves 502 are connected on the L-shaped liquid spraying pipe 404 from one end to the other end. The inside of the L-shaped pumping and pressure pipe 501 is slidably connected to a piston plate 503, and the end of the L-shaped pumping and pressure pipe 501 is slidably connected to a push rod 504, and one end of the push rod 504 The first end of the L-shaped pumping and pressing tube 501 is fixed to the piston plate 503, and a first extrusion assembly for extruding the push rod 504 is provided on the rotating shaft 302. A first spring 505 is sleeved on the outer side of the push rod 504, and the two ends of the first spring 505 are respectively connected to the inside of the L-shaped pumping and pressing tube 501 and the piston plate 503; the first extrusion assembly includes a first driving disk 601 fixed to the rotating shaft 302, and a plurality of first protrusions 602 for abutting and extruding against the end of the push rod 504 are fixed on the outer side of the first driving disk 601 in a state of an annular array;

[0039] It should be noted here that: during the rotation of the rotating shaft 302, the first driving disk 601 is driven to rotate. During the rotation of the first driving disk 601, each group of first protrusions 602 is sequentially abutted against one end of the push rod 504. Through the abutting and squeezing effect of each group of first protrusions 602 on one end of the push rod 504 and the reset effect of the first spring 505 on the push rod 504 after being stressed, the push rod 504 and the piston plate 503 reciprocate on the L-shaped suction and pressure tube 501 as the first driving disk 601 rotates. Due to the conduction of the two groups of one-way valves 502, the L-shaped spray pipe 404 leans against one end of the mounting pipe 402 to the other end. Through the reciprocating motion of the piston plate 503, the treatment liquid inside the mounting pipe 402 and the storage tank 403 is sucked and pressed between the two groups of one-way valves 502 of the L-shaped spray pipe 404 and sprayed out from each group of spray holes 405 through squeezing.

[0040] Preferably, the separation assembly includes a strip plate 701 disposed inside the drum 1, a mounting hole 702 is opened on the strip plate 701, and the strip plate 701 is sleeved and fixed on the outer side of the L-shaped liquid spraying pipe 404 under the action of the mounting hole 702, and a scraper 703 is connected to the strip plate 701 through an elastic component, and the scraper 703 is kept against the top of the inner side of the drum 1 under the elastic force of the elastic component;

[0041] It should be noted here that: because the scraper 703 is kept against the inner side of the rotating drum 1 under the elastic force of the elastic component, the scraper 703 is against the sticky soil adhering to the inner wall of the drum 1, so that the sticky soil is separated from the inner wall of the drum 1 and falls onto the material guide cover plate 901 under the action of gravity.

[0042] Preferably, the elastic component includes a plurality of groups of T-shaped rods 801 slidably connected to the strip plate 701, one end of each group of T-shaped rods 801 is fixed to the scraper 703, and a second spring 802 is sleeved on the outer side of the T-shaped rod 801, and both ends of the second spring 802 are respectively connected to one end of the T-shaped rod 801 and the strip plate 701;

[0043] It should be noted here that: each group of T-bars 801 facilitates the extension and retraction guidance of the scraper 703 after being stressed, and the elastic force of each group of second springs 802 and the connecting action of the T-bars 801 facilitate the scraper 703 to be pushed to maintain contact with the inner wall of the drum 1.

[0044] Preferably, two groups of processing components are provided, and the two groups of processing components are symmetrically arranged on both sides of the scraper 703. The processing components include a material guide cover plate 901 arranged inside the drum 1, the material guide cover plate 901 is arranged in an inclined state, and the inclination direction of the material guide cover plate 901 is consistent with that of the drum 1. The material guide cover plate 901 is provided with multiple groups of separation holes 902 for separating the liquid inside the soil after falling. The strip plate 701 is provided with a connecting component for connecting the material guide cover plates 901 on the two groups of processing components, and the rotating shaft 302 is provided with a second extrusion component for extruding the material guide cover plate 901;

[0045] It should be noted that: the scraper 703 and the sticky soil adhering to the inner wall of the drum 1 are offset against each other, so that the sticky soil is separated from the inner wall of the drum 1 and falls onto the guide cover plate 901 under the action of gravity. The two sets of guide cover plates 901 are driven to reciprocate and vibrate synchronously through the cooperation of the connecting component and the second extrusion component. Since the guide cover plates 901 are inclined, the sticky soil scraped and separated onto the guide cover plates 901 is transported on the guide cover plates 901 and finally moved to the guide cover plates 901 through the reciprocating motion and vibration of the guide cover plates 901. In the process of guiding the viscous soil through the guide cover plate 901, the vibration of the guide cover plate 901 can ensure the normal discharge of the viscous soil on the guide cover plate 901. Secondly, the vibration of the guide cover plate 901 can assist the separation of excess liquid medicine contained in the viscous soil transported on the guide cover plate 901 under the action of vibration and return it to the inside of the drum 1 through the separation hole 902 for reuse, thereby reducing the probability of soil adhesion during the process of liquid medicine spraying treatment and recovery, and ensuring the effect of restoring the contaminated soil.

[0047] It should be noted here that: the multiple sets of sleeves 1002 and slide rods 1003 facilitate the telescopic connection of the connecting plate 1001, and the third spring 1004 facilitates the reset of the connecting plate 1001 after the contraction movement.

[0048] Preferably, the second extrusion assembly includes a support frame 1101 fixed to the upper end of the strip plate 701, the support frame 1101 is rotatably connected to a transmission shaft 1102, a second drive disk 1103 is fixed to the transmission shaft 1102, a plurality of groups of second protrusions 1104 arranged in a circular array and used to press against the connecting plate 1001 are fixed to the outer side of the second drive disk 1103, and the transmission shaft 1102 is connected and transmitted to the rotating shaft 302 through a transmission assembly;

[0049] It should be noted here that: during the rotation of the rotating shaft 302, the transmission shaft 1102 and the second driving disk 1103 on the transmission shaft 1102 are driven to rotate through the connecting transmission action of the transmission assembly. During the rotation of the second driving disk 1103, the groups of second protrusions 1104 on the second driving disk 1103 are sequentially pressed against the connecting plate 1001 and the third spring 1004 on the connecting assembly resets the connecting plate 1001 after being squeezed, so that the connecting plate 1001 reciprocates up and down with the rotation of the rotating shaft 302 and vibrates under the elastic force of the third spring 1004.

[0050] Preferably, the transmission assembly includes pulleys 1201 fixed on the transmission shaft 1102 and the rotating shaft 302, and the two sets of pulleys 1201 are connected and transmitted via a belt 1202;

[0051] It should be noted here that: during the rotation of the rotating shaft 302 , the transmission shaft 1102 rotates along with the rotation of the rotating shaft 302 through the interaction between the belt 1202 and the two sets of pulleys 1201 .

[0052] In this scheme: a liquid spraying device for soil heavy metal pollution control includes the following steps:

[0053] In the process of treating heavy metal contaminated soil by a liquid medicine spraying device, the heavy metal contaminated soil to be treated is put into the interior of the drum 1. After being put in, the gear 303 on the rotating shaft 302 is driven to rotate by the driving motor 305. During the rotation of the gear 303, the drum 1 is driven to move by the mutual meshing transmission between the gear 303 and the gear ring 304. During the process of the drum 1 being stressed, the drum 1 is rotated on each group of mounting sleeves 201 through the rotation connection between the annular groove 203 and the annular plate 204. Since the drum 1 is arranged in an inclined state, during the rotation of the drum 1, the heavy metal contaminated soil put into the drum 1 is transported toward the inclined side of the drum 1.

[0054] During the rotation of the rotating shaft 302, the first driving disk 601 is driven to rotate. During the rotation of the first driving disk 601, each group of first protrusions 602 is sequentially abutted against one end of the push rod 504. Through the abutting and squeezing effect of each group of first protrusions 602 on one end of the push rod 504 and the reset effect of the first spring 505 on the push rod 504 after being stressed, the push rod 504 and the piston plate 503 reciprocate on the L-shaped pumping and pressure pipe 501 as the first driving disk 601 rotates. Due to the conduction of the two groups of one-way valves 502, the L-shaped liquid spraying pipe 404 is close to one end of the installation pipe 402 to the other end. , through the reciprocating motion of the piston plate 503, the treatment liquid inside the installation pipe 402 and the storage tank 403 is pumped and pressed between the two groups of one-way valves 502 of the L-shaped spray pipe 404 and sprayed outward from each group of spray holes 405 through extrusion, and the sprayed treatment liquid falls on the heavy metal contaminated soil transported inside the drum 1. The sprayed treatment liquid can form a stable chelate with the heavy metal ions in the soil. The chelating agent molecule has multiple coordinated atoms and can form a ring structure with the heavy metal ions, thereby increasing the stability and dissolution of the heavy metal ions, thereby achieving the restoration treatment of the heavy metal contaminated soil;

[0055] During the liquid spraying treatment process, part of the soil will adhere to each other due to the excessive amount of treatment liquid sprayed. The soil that adheres to each other will adhere to the inner side of the drum 1 due to its own viscosity and move synchronously with the rotation of the drum 1. Because the scraper 703 is kept against the inner side of the rotating drum 1 under the elastic force of the elastic component, the scraper 703 and the sticky soil adhered to the inner wall of the drum 1 are offset, so that the sticky soil is separated from the inner wall of the drum 1 and falls onto the guide cover plate 901 under the action of gravity. Similarly, during the rotation of the rotating shaft 302, the transmission shaft 1102 and the second driving disk 1103 on the transmission shaft 1102 are driven to rotate through the connection transmission action of the transmission component. During the rotation of the second driving disk 1103, the connecting plate 1001 is pressed against each other by each group of second protrusions 1104 on the second driving disk 1103 and the third spring 1004 on the connecting component resets the connecting plate 1001 after being squeezed. As the rotating shaft 302 rotates, it reciprocates up and down and vibrates under the elastic force of the third spring 1004. During the movement of the connecting plate 1001, the two sets of guide shield plates 901 are driven to reciprocate and vibrate synchronously. Since the guide shield plates 901 are arranged at an angle, the reciprocating motion and vibration of the guide shield plates 901 cause the viscous soil that is scraped and separated onto the guide shield plates 901 to be transported on the guide shield plates 901 and finally discharged outwards. In the process of guiding the material, the vibration of the material guide cover plate 901 can ensure the normal discharge of the sticky soil on the material guide cover plate 901. Secondly, the vibration of the material guide cover plate 901 can assist the separation of the excess liquid medicine contained in the sticky soil transported on the material guide cover plate 901 under the action of vibration and return it to the inside of the drum 1 through the separation hole 902 for reuse, thereby reducing the probability of soil adhesion during the process of liquid medicine spraying treatment and restoration, and ensuring the effect of restoring the contaminated soil.
