Description

Technical Field

[0001] The present invention relates to the technical field of soil treatment, and in particular to a purification device for treating heavy metal pollution in soil. Background Art

[0002] Improper industrial discharge of wastewater and waste residue from industries such as metallurgy, electroplating, and chemical industry, as well as agricultural pollution caused by the long-term use of pesticides and fertilizers containing heavy metals (such as cadmium in phosphate fertilizers) and sewage irrigation are the main sources of heavy metal formation in the soil. They not only directly destroy soil microbial communities and reduce fertility, but also accumulate through the food chain, affecting the growth of animals and plants and posing a threat to human health.

[0003] Prior to mixing the chemical with the soil, existing technologies often rely on simple stirring or tilling to pre-treat the soil to improve the uniformity of the chemical-chemical contact reaction. However, in practice, the lack of an efficient pre-crushing step prevents large clumps of soil from reacting with the chemical, resulting in low reaction efficiency. This approach is particularly unsuitable for heavy clay soils. Summary of the Invention

[0004] The purpose of the present invention is to provide a purification device for controlling heavy metal pollution in soil. The conical spiral column and the vibrating barrel form a coordinated transmission, which can feed the soil to the vibrating barrel while using the crushing teeth to perform preliminary crushing of the soil. The curved circular slide and the sliding wheel form rolling contact, driving the vibrating barrel to form a reciprocating up and down movement in a rotating state, and using the raking component to perform multiple crushing operations on the soil before it enters the reaction barrel, so that the soil can be fully crushed before reacting with the agent, and using the cooperation of the lifting component and the vibrating scattering component to realize the lifting and turning of the soil particles entering the reaction barrel during the spraying of the agent by the agent spraying component, thereby improving the uniformity of the reaction contact between the agent and the soil particles.

[0005] The objective of the present invention is achieved through such a technical solution, a purification device for treating heavy metal pollution in soil, comprising a processing frame assembly, an internal reaction barrel assembly, a vibrating bulk material assembly, a raking and dispersing component, a drug spraying assembly and a lifting component, wherein the processing frame assembly comprises a main barrel body and crushing teeth, the internal reaction barrel assembly comprises a reaction barrel, the vibrating bulk material assembly comprises a vibrating barrel, a curved circumferential slideway and a sliding wheel, the raking and dispersing component comprises a raking claw, the drug spraying assembly comprises a spraying pipe, and the lifting component comprises a lifting claw;

[0006] A conical spiral column is screwed onto the top wall of one side of the main barrel body, and crushing teeth are provided on the spiral outer surface of the conical spiral column. The reaction barrel is screwed onto the inner bottom end of the main barrel body, and a hexagonal column is screwed onto the middle part of the inner upper end of the main barrel body. The inner middle part of the vibrating barrel is upwardly elastic and slidably connected with the hexagonal column, and the curved circumferential slide is fixedly connected to the outside of the vibrating barrel. The bottom surfaces of the sliding wheels screwed onto the inner wall of the main barrel body are all rollingly connected to the top surface of the curved circumferential slide, and the top end of the curved circumferential slide is transmission-connected to the top end of the conical spiral column, and the rake claw is downwardly elastic and slidably connected to the inner upper part of the main barrel body.

[0007] A Y-shaped fixed pipe is fixedly connected to the inner middle part of the main barrel body, the spraying pipe is installed in the branch pipe of the Y-shaped fixed pipe, the outer bottom of the vibrating barrel is screwed with a top connecting rotary seat, and the top ends of the arranged lifting claws are respectively slidably connected to the Y-shaped fixed pipe and are all fixed to the top connecting rotary seat.

[0008] The use process of the technical solution of the present invention is as follows:

[0009] When the conical spiral column rotates, the soil to be processed outside can be transported to the inner top of the main barrel by the conical spiral column and fall into the inner groove of the vibrating barrel. The bottom of the vibrating barrel is provided with a vibrating sieve hole. When the conical spiral column rotates, it can synchronously drive the hexagonal column to form a rotating action, and the hexagonal column drives the vibrating barrel to rotate. When the vibrating barrel rotates, it can drive the vibrating barrel to move back and forth up and down along the undulating path of the curved circumferential slideway fixed to the vibrating barrel through the upward elasticity and the coordinated transmission formed by the sliding wheel, thereby driving the vibrating barrel to move up and down along the undulating path of the curved circumferential slideway itself during rotation, and performing a vibrating sieve action on the soil falling into the inner groove of the vibrating barrel;

[0010] Within the range of the vibrating barrel's up and down reciprocating movement, the bottom end of the rake claw always elastically contacts the inner groove surface of the vibrating barrel. In conjunction with the rotation and up and down reciprocating movement of the vibrating barrel itself, the rake claw can crush the soil that enters the inner groove of the vibrating barrel.

[0011] The crushed soil particles fall down into the inner cavity of the reaction barrel. When they accumulate to a certain level, the external agent supply device connected to the spraying pipe is activated, so that the treatment agent is sprayed downward from the outlet of each group of spraying pipes into the inner cavity of the reaction barrel.

[0012] The agent interacts with heavy metals in the soil to dissolve the heavy metals. The heavy metals can be recovered through subsequent soil leaching and remediation processes, thus achieving the purification of heavy metals in the soil.

[0013] After a layer of soil particles is spread on the bottom of the inner cavity of the reaction barrel, the external reagent supply device connected to the spraying pipe can be started, so that as the soil particles fall from the vibrating barrel to the reaction barrel, the reagents continuously sprayed from the spraying pipe can evenly contact and react with the soil particles;

[0014] In addition, the reaction barrel itself can also rotate automatically, and cooperate with the vibrating barrel to move back and forth, which can drive the top connecting rotary seat and lifting claws that are slidably connected to the Y-shaped fixed tube and screwed to the outer bottom of the vibrating barrel to form a reciprocating up and down movement, so that the lifting claws can form a lifting and flipping action on the soil particles that fall into the reaction barrel, so that the contact reaction between the soil particles in the reaction barrel and the reagent is more uniform.

[0015] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0016] (1) The purpose of the present invention in providing a tapered spiral column with a variable pitch structure is to provide a larger accommodation space through the large diameter of the inlet end to prevent soil accumulation and blockage. At the same time, the crushing teeth provided on the outer surface of the spiral column can utilize the conical surface to generate radial extrusion force, thereby promoting frictional crushing of soil particles.

[0017] (2) When the conical spiral column rotates, the present invention can also synchronously drive the hexagonal column to form a continuous rotation movement. The vibrating barrel that is elastically slidably connected to the hexagonal column upwards, in conjunction with the rolling contact formed by the curved circumferential slideway on the outside of the vibrating barrel and the sliding wheel at a fixed position, can drive the vibrating barrel to form a reciprocating up and down movement while rotating; the reciprocating up and down movement of the vibrating barrel itself can not only form a vibrating sieve effect, but also, in conjunction with the rotation of the vibrating barrel itself, will cause the rake claws that are always in contact with the inner groove surface of the vibrating barrel to form a rake-scattering operation on the soil that falls into the inner groove of the vibrating barrel, thereby efficiently crushing the soil;

[0018] (3) After the soil particles fall from the vibrating barrel into the reaction barrel, the reciprocating up and down movement of the vibrating barrel can also drive the lifting claws located in the inner cavity of the reaction barrel to form a lifting action in conjunction with the spraying operation of the spray pipe, thereby improving the uniformity of the contact reaction between the soil particles and the reagent.

[0040] like Figures 1-16 As shown, a purification device for treating heavy metal pollution in soil is provided. A conical spiral column 105 is screwed to the top wall of one side of the main barrel body 102 in the processing frame assembly 1. The conical spiral column 105 is not only a conical structure, but also has a pitch that gradually decreases toward the main barrel body 102, which can realize the feeding work from a low position to a high position. The outer surface of the spiral of the conical spiral column 105 is provided with a crushing tooth 111. The reaction barrel 202 is screwed to the inner bottom of the main barrel body 102. At the end, a hexagonal prism 304 is screwed to the middle of the inner upper end of the main barrel body 102, and the inner middle part of the vibrating barrel 307 is upwardly elastic and slidably connected to the hexagonal prism 304. A curved circumferential slide 308 is fixed to the outside of the vibrating barrel 307. The bottom surfaces of the screwed sliding wheels 309 arranged on the inner wall of the main barrel body 102 are all rollingly connected to the top surface of the curved circumferential slide 308. The top end of the curved circumferential slide 308 is transmission-connected to the top end of the conical spiral column 105.

[0041] The curved circumferential slideway 308 is formed by connecting a plurality of curved paths with the same undulating path. The bottom surfaces of the plurality of sliding wheels 309 arranged and screwed on the inner wall of the main barrel 102 can be rollingly connected to the same position of the top of each group of curved paths with the same undulating path in the curved circumferential slideway 308.

[0042] The rake claw 405 is slidably connected to the inner upper part of the main barrel 102 by sliding downward, and the bottom of the rake claw 405 is inserted into the inner groove of the vibrating barrel 307;

[0043] A Y-shaped fixed pipe 505 is fixedly connected to the inner middle of the main barrel 102, and the Y-shaped fixed pipe 505 is located directly above the reaction barrel 202. The spray pipe 503 is installed in the branch pipe of the Y-shaped fixed pipe 505 and is connected to the external drug supply device;

[0044] The outer bottom of the vibrating barrel 307 is screwed with a top connecting seat 603. The top ends of the arranged lifting claws 605 are respectively slidably connected to the Y-shaped fixed tube 505 and fixedly connected to the top connecting seat 603, and extend into the inner cavity of the reaction barrel 202.

[0045] Here’s how it works:

[0046] When the conical spiral column 105 rotates, the soil to be processed externally can be transported to the inner top of the main barrel 102 by the conical spiral column 105 and fall into the inner groove of the vibrating barrel 307. The bottom of the vibrating barrel 307 is provided with a vibrating sieve hole, and since the top of the hexagonal column 304 is connected to the top of the conical spiral column 105 by transmission, when the conical spiral column 105 rotates, it can synchronously drive the hexagonal column 304 to form a rotation action, and the hexagonal column 304 drives the vibrating barrel 307 to rotate. 07 is elastically slidably connected with the hexagonal prism 304 upward, and the top end of the curved circumferential slideway 308 is always in elastic rolling contact with the sliding wheel 309. When the vibrating barrel 307 rotates, the upward elastic movement of the curved circumferential slideway 308 fixed to the vibrating barrel 307 and the coordinated transmission formed by the sliding wheel 309 can drive the vibrating barrel 307 to move up and down along the undulating path of the curved circumferential slideway 308 itself during rotation, thereby vibrating and screening the soil that falls into the inner groove of the vibrating barrel 307;

[0047] Furthermore, driven by the downward springing of the rake claws 405, within the range of the up-and-down reciprocating movement of the vibrating barrel 307, the bottom end of the rake claws 405 always elastically abuts against the inner groove surface of the vibrating barrel 307. In conjunction with the rotation and up-and-down reciprocating movement of the vibrating barrel 307, the rake claws 405 can crush the soil entering the inner groove of the vibrating barrel 307, thereby eliminating lumps in the soil and forming uniform granules, which facilitates the soil to enter the reaction barrel 202 in the form of granules for the drug spraying treatment operation.

[0048] The crushed soil particles fall downward into the inner cavity of the reaction barrel 202. When they accumulate to a certain level, the external agent supply device connected to the spraying pipe 503 is activated, so that the treatment agent is sprayed downward from the outlet of each group of spraying pipes 503 into the inner cavity of the reaction barrel 202.

[0049] The agent interacts with heavy metals in the soil to dissolve the heavy metals. The heavy metals can be recovered through subsequent soil leaching and remediation processes, thus achieving the purification of heavy metals in the soil.

[0050] The dosage of the spray agent is determined by the processing capacity of the reaction barrel 202. After a layer of soil particles is evenly spread on the bottom surface of the inner cavity of the reaction barrel 202, the external agent supply device connected to the spray pipe 503 can be activated. As the soil particles fall from the vibrating sieve of the vibrating barrel 307 to the reaction barrel 202, the agent continuously sprayed from the spray pipe 503 can evenly contact and react with the soil particles.

[0051] Furthermore, the reaction barrel 202 itself can also rotate automatically, cooperating with the reciprocating up and down movement of the vibrating barrel 307, which can drive the top connecting rotary seat 603 and the lifting claw 605, which are slidably connected to the Y-shaped fixed tube 505 and screwed to the outer bottom of the vibrating barrel 307, to form a reciprocating up and down movement. Due to the unique arrow-shaped structure of the lifting claw 605 itself, the lifting claw 605 can form a lifting and flipping action on the soil particles that fall into the reaction barrel 202, so that the contact reaction between the soil particles in the reaction barrel 202 and the reagent is more uniform;

[0052] The bottom of the reaction barrel 202 is provided with a normally closed outlet, which can discharge the soil particles after being treated with the chemical.

[0055] The soil to be processed is poured into the feeding box 103. After the conical spiral column 105 rotates, it cooperates with the crushing teeth 111 provided on the spiral outer surface of the conical spiral column 105 to crush and transport the soil entering the conical barrel 104.

[0056] The soil particles initially crushed by the conical spiral column 105 enter the feed box 107 and then fall downward from the feed hole 109 into the inner groove of the vibrating cylinder 307.

The coil spring 705 can form a supporting elastic force for the rotation of the discharge rotary plate 703 relative to the fixed shaft 702, so that when there is no external force, the discharge rotary plate 703 will rotate to a position that covers the discharge hole 701, and the positioning arm 706 just contacts the positioning block 707, so that the reaction barrel 202 can safely process soil particles.

[0074] The pushing slide 709 is fixedly installed at the lower end of the side wall of the main barrel body 102, and the pushing rack 710 is slidably connected to the pushing slide 709. A side rod 711 is fixedly connected to one side of the pushing slide 709, and a travel switch 712 is installed and fixed on the top of the side rod 711 in pairs. A trigger block 713 is fixedly installed on the top of the pushing rack 710. A pushing motor 714 is fixed on one side of the base 101. A pushing gear 715 is inserted and fixed in the rotating shaft of the pushing motor 714, and the pushing gear 715 is engaged with the pushing rack 710, which can drive the pushing rack 710 to form a sliding action in the pushing slide 709, and the touching of the two sets of travel switches 712 by the trigger block 713 can control the moving stroke of the pushing rack 710, so that when the reaction barrel 202 is in the state of processing soil particles, the pushing rack 710 moves to a position where it does not contact the opening gear 708 and does not interfere with the rotation of the reaction barrel 202;

[0075] The reaction barrel 202 itself can achieve a fixed stop relative to the rotation position of the rotary sleeve 201. There are many methods for controlling the fixed-point rotation and stop of the reaction barrel 202. This can be achieved by a servo driver connected to the servo motor 205. It can also be achieved by installing a touch switch between the reaction barrel 202 and the main barrel body 102. This is a prior art and will not be described in detail.

[0076] The outer wall of the discharge hopper 801 is fixedly connected to the bottom main body of the main barrel body 102, and the discharge auger 802 is screwed to the inner lower end of the discharge hopper 801. Side rotating seats 803 are fixedly installed at both ends of the lower side wall of the discharge hopper 801. The two ends of the rotating shaft of the discharge auger 802 are respectively rotatably connected to the side rotating seats 803 at different positions. The bottom end of the main rotating shaft 301 is plugged and fixed with a discharge transmission bevel gear 805, and one side of the discharge transmission bevel gear 805 is meshed with a discharge bevel gear 804. The discharge bevel gear 804 is plugged and fixed to the outer end of the rotating shaft of the discharge auger 802;

[0077] After the soil particles in the reaction barrel 202 have been reacted and processed, the reaction barrel 202 rotates to a position where the discharge hole 701 is directly opposite to the top opening of the discharge hopper 801 in conjunction with its own fixed-point rotation stop. The trigger block 713 touches the travel switch 712 to push the rack 710 inward to a position where it meshes with the opening gear 708. The rack 710 cooperates with the opening gear 708 to overcome the supporting elastic force of the coil spring 705, and the discharge rotary plate 703 rotates to a position where the discharge hole 701 is opened.

[0078] The processed soil particles in the reaction barrel 202 fall downward from the discharge hole 701 into the discharge hopper 801. During the rotation of the main rotating shaft 301, it can not only drive the lifting claw 605 through the transmission mechanism to perform a reciprocating lifting operation in the reaction barrel 202 to prevent the processed soil particles from piling up in the reaction barrel 202, but also drive the rotation of the discharge auger 802 to automatically discharge the soil particles into the discharge hopper 801.
