Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically a novel high-efficiency chemical leaching device for soil remediation. Background Technology

[0002] Soil is an important component of the ecosystem and the material basis for human survival and development. However, in recent years, due to industrial wastewater discharge, excessive use of pesticides and fertilizers, and improper disposal of solid waste, a large amount of pollutants have entered the soil environment, leading to a decline in soil quality and damage to ecosystem functions.

[0003] Chemical leaching technology utilizes the physical and chemical reactions between the leaching solution and pollutants in the soil to separate and dissolve the pollutants from the soil and remove them with the leaching solution, thereby achieving the purpose of soil remediation. Its basic principles include dissolution, ion exchange, and complexation.

[0004] Current chemical leaching devices for soil remediation are relatively simple, mainly consisting of a leaching solution storage tank, a delivery pipeline, and a spraying device. Operators manually control the flow rate and spraying range of the leaching solution to spray it onto the surface of the contaminated soil, allowing it to penetrate into the soil for leaching.

[0005] In traditional chemical leaching operations for soil remediation, manual spraying requires operators to hold spraying equipment and walk back and forth in the contaminated soil area to spray. For large-scale contaminated soil remediation projects, operators need to perform high-intensity physical labor for a long time, which can easily lead to fatigue, affecting work efficiency and quality, resulting in low work efficiency. Moreover, prolonged exposure to chemical leaching solutions may also cause health hazards to operators, such as skin allergies and respiratory irritation.

[0006] Therefore, in response to the above problems, the applicant needs to design a new and efficient chemical leaching device for soil remediation to solve the problem. Utility Model Content

[0007] The purpose of this invention is to provide a novel and efficient chemical leaching device for soil remediation, in order to solve the problems mentioned in the background section.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel high-efficiency chemical leaching device for soil remediation, comprising a support frame, and rollers are provided on the support frame.

[0009] It also includes: a water storage tank placed on a support frame, and a connecting pipe connected to the water storage tank; a rinsing mechanism is fixedly installed at the end of the connecting pipe away from the water storage tank; the rinsing mechanism is used to rinsing the soil; the rinsing mechanism includes a connecting pipe, and a rinsing pipe is fixedly connected to the outlet end of the connecting pipe; an extension pipe is connected to the rinsing pipe, and both the extension pipe and the rinsing pipe are equipped with rinsing nozzles for rinsing the soil; a buffer component is installed at the inlet end of the connecting pipe, and the buffer component is used to mix chemical agents and clean water.

[0010] Furthermore, a support column is fixedly installed on the extended pipe, and an installation component is installed on the support column, with the installation component fixedly connected to the support frame.

[0011] Furthermore, the buffer component includes a mixing chamber that is fixedly connected to the connecting pipe, and the mixing chamber is fixedly connected to the support frame. The mixing chamber is provided with a liquid inlet pipe, and the liquid inlet pipe is integrally connected to the connecting pipe.

[0012] Furthermore, the mixing chamber is equipped with a feed hopper for dispensing chemical agents, and the feed hopper is hinged with a movable cover, which is equipped with a fixed handle.

[0013] Furthermore, the connecting pipe is equipped with a detachable double-connector.

[0014] Furthermore, an extension rod is fixedly installed on the support frame, and a push-pull handle is fixedly installed at the end of the extension rod away from the support frame.

[0015] Furthermore, a waterproof compartment is provided below the partition box, and the interior of the waterproof compartment is filled with alumina ceramic powder.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this novel high-efficiency soil remediation chemical leaching device facilitates the mixing of chemical agents and water, and makes it easy to leach the soil with the mixture. It is convenient to operate and has high working efficiency. The specific details are as follows:

[0017] When using this new high-efficiency chemical leaching device for soil remediation, the operator first adds chemical agents to the mixing chamber through the feed hopper. At the same time, clean water from the storage tank is fed into the mixing chamber through connecting pipes and liquid inlet pipes, achieving initial mixing of the agents and clean water to form a leaching solution. The mixed leaching solution flows into the connecting pipes and is then distributed to the leaching pipes and extension pipes. Finally, it is sprayed onto the surface of the contaminated soil through evenly distributed leaching nozzles. Under the action of gravity and permeation, the leaching solution penetrates deep into the soil layer, separating pollutants from soil particles through dissolution, ion exchange, or complexation, and migrating them with the liquid flow, thereby completing the remediation. During the process, the operator can push and pull the support frame with rollers to flexibly move the device to cover a large working area. The mixing chamber of the buffer component ensures uniform chemical activity of the leaching solution, while the support columns and mounting parts maintain the stability of the spraying structure. The double-joint facilitates pipeline maintenance. The overall design realizes automatic mixing of agents, precise spraying, and efficient coverage, reducing the intensity of manual operation and health risks. Attached Figure Description

[0023] 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.

[0024] like Figures 1-4As shown, this utility model discloses a novel high-efficiency chemical leaching device for soil remediation, comprising a support frame 1 with rollers 10 on it, and a water storage tank 11 placed on the support frame 1. A connecting pipe 12 is connected to the water storage tank 11, and a leaching mechanism 2 is fixedly installed at the end of the connecting pipe 12 away from the water storage tank 11. The leaching mechanism 2 is used for leaching soil. The leaching mechanism 2 includes a connecting pipe 21, and a leaching pipe 22 is fixedly connected to the outlet end of the connecting pipe 21. An extension pipe 23 is connected to the leaching pipe 22, and both the extension pipe 23 and the leaching pipe 22 are equipped with leaching nozzles 24 for leaching soil. A buffer component 20 is installed at the inlet end of the connecting pipe 21, and the buffer component 20 is used to mix chemical agents and clean water.

[0025] A support column 25 is fixedly installed on the extension pipe 23, and an installation component 26 is installed on the support column 25. The installation component 26 is fixedly connected to the support frame 1. By setting the support column 25 and the installation component 26 to fix the extension pipe 23 to the support frame 1, the structural stability of the rinsing pipe 22 and the extension pipe 23 is enhanced. This effectively prevents the pipe from shifting or vibrating due to water pressure or external interference during the rinsing operation, ensuring that the spraying range of the rinsing nozzle 24 accurately covers the target soil area, improving the uniformity of rinsing and the repair effect, while reducing the risk of wear caused by mechanical vibration of the equipment.

[0026] The buffer component 20 includes a mixing chamber 200, which is fixedly connected to the support frame 1. The mixing chamber 200 is equipped with an inlet pipe 204, which is integrally connected to the connecting pipe 12. The integrated design of the mixing chamber 200 and the inlet pipe 204 realizes the pre-mixing function of chemical agents and water before entering the rinsing pipe 22, so that the agents and water can fully contact and react in the buffer space, avoiding the direct entry of insufficiently mixed agents into the soil, which would cause uneven local concentration. This improves the chemical activity uniformity of the rinsing solution, enhances the efficiency of pollutant dissolution or complexation, and ultimately improves the quality of soil remediation.

[0027] The mixing chamber 200 is equipped with a feed hopper 201 for dispensing chemical agents. A movable cover 202 is hinged to the feed hopper 201, and a fixed handle 203 is provided on the movable cover 202. The feed hopper 201, together with the hinged movable cover 202 and the fixed handle 203, provides a convenient and safe operating entrance for dispensing chemical agents. The movable cover 202 can be opened and closed quickly, which can prevent external impurities from contaminating the agents in the mixing chamber 200 and also prevent the escape of volatile gases from the rinsing liquid, reducing the risk of operators coming into contact with harmful chemicals. The fixed handle 203 facilitates operation, improves operational safety and agent addition efficiency.

[0028] The connecting pipe 12 is equipped with a detachable double joint 13. The design of the detachable double joint 13 gives the connecting pipe 12 modular characteristics. When the pipe is blocked or needs maintenance, the faulty section can be quickly disassembled and cleaned, avoiding the shutdown of the entire system due to local blockage. At the same time, it simplifies the pipe expansion or reorganization process, adapts to the layout requirements of different operating scenarios, and greatly reduces equipment maintenance costs and time loss.

[0029] An extension rod 14 is fixedly installed on the support frame 1, and a push-pull handle 15 is fixedly installed at the end of the extension rod 14 away from the support frame 1. The addition of the extension rod 14 and the push-pull handle 15 greatly optimizes the mobility and maneuverability of the equipment. Operators do not need to directly contact the main body of the equipment. They can move the device flexibly in the contaminated area by pushing and pulling the handle 15, thus ensuring operational safety.

[0030] Working Principle: When using this new high-efficiency chemical leaching device for soil remediation, the operator first adds chemical agents into the mixing chamber 200 through the feed hopper 201. Simultaneously, clean water from the water storage tank 11 is fed into the mixing chamber 200 via the connecting pipe 12 and the liquid inlet pipe 204, achieving initial mixing of the agents and water to form a leaching solution. The mixed leaching solution flows into the connecting pipe 21 and is then distributed to the leaching pipe 22 and the extension pipe 23. Finally, it is sprayed onto the surface of the contaminated soil through evenly distributed leaching nozzles 24. Under the influence of gravity and infiltration, the leaching solution penetrates deep into the soil layer. The process involves separating pollutants from soil particles through dissolution, ion exchange, or complexation, and migrating them with the liquid flow to complete the remediation. During the process, operators can push the support frame 1 with rollers 10 to move the device flexibly by pushing and pulling the handle 15, covering a large working area. The mixing chamber 200 of the buffer component 20 ensures uniform chemical activity of the rinsing solution. The support column 25 and the mounting component 26 maintain the stability of the spraying structure. The double-connector 13 facilitates pipeline maintenance. The overall design realizes automatic mixing of agents, precise spraying, and efficient coverage, reducing the intensity of manual operation and health risks.

[0031] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
