Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and more specifically, to a soil remediation agent mixing device. Background Art

[0002] Soil remediation is a technical measure to restore contaminated soil to its normal function. It refers to the use of physical, chemical, and biological methods to transfer, absorb, degrade, and transform pollutants in the soil, reducing their concentration to acceptable levels, or converting toxic and harmful pollutants into harmless substances. Fundamentally, contaminated soil remediation technologies include: altering the form of pollutants in the soil or their binding method, reducing their mobility and bioavailability in the environment; and reducing the concentration of harmful substances in the soil. Chemical methods of soil remediation require the preparation of chemical agents, which often need to be prepared on-site.

[0003] For example, the existing patent CN213528490U describes a soil remediation agent mixing device. The soil remediation agent is put into the inner cavity of the mixing box, and impurities in the agent are removed by filtering through a filter screen. Then, the stirring rod drives the stirring blade to rotate and mix the remediation agent. Although this device has many beneficial effects, the mixing efficiency of the stirring blade is relatively slow when mixing the remediation agent. In view of this, we propose a soil remediation agent mixing device. Utility Model Content

[0004] The purpose of this invention is to provide a soil remediation agent mixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A soil remediation agent mixing device includes a mixing box, a rotating shaft is provided inside the mixing box and rotatably connected to the mixing box, and a sliding groove is provided on both sides of the rotating shaft. The sliding groove has a T-shaped cross-section and a sliding strip is provided inside the sliding groove. A cavity is formed between the two ends of the sliding strip along its length direction and the end of the sliding groove. An elastic element is provided at the end of the sliding strip.

[0007] Multiple stirring shafts are provided on the outside of the slide bar, and multiple blades are provided on the stirring shafts. The blades have a spiral structure.

[0008] Preferably, a motor is installed on the top of the mixing tank, and the output shaft of the motor is connected to the rotating shaft.

[0009] Preferably, the bottom of the mixing box is a downward-sloping arc-shaped concave surface, with a discharge port in the middle of the arc-shaped concave surface, and an arc-shaped stirring rod assembly is provided at the end of the rotating shaft.

[0010] Preferably, a plurality of connecting pipes are provided through the top surface of the mixing chamber, and a nozzle is connected to one end of the connecting pipes extending into the mixing chamber.

[0011] Preferably, an regulating vent is provided on one side of the top surface of the mixing tank, and a valve is provided on the regulating vent.

[0012] Preferably, a support frame is provided at the bottom of the mixing chamber, and a temperature regulating cavity is provided on the inner wall of the mixing chamber, with a spiral tube installed inside the temperature regulating cavity.

[0013] Preferably, the elastic element is a spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention features a sliding strip that engages with a groove on a rotating shaft, and a spiral-shaped blade. As the blade rotates, the liquid is agitated from different directions, facilitating rapid and uniform mixing of the repair agent and water. When water flows over the blade, it pushes the sliding strip along the groove. An elastic element at the end of the sliding strip causes it to reciprocate when it slides along the groove, causing the blade to move vertically. This multi-directional flow of liquid within the mixing chamber improves the mixing efficiency of the repair agent and water. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example:

[0022] Please see Figure 1-3A soil remediation agent mixing device includes a mixing box 1, a rotating shaft 2 inside the mixing box 1, the rotating shaft 2 being rotatably connected to the mixing box 1, and a sliding groove 201 on both sides of the rotating shaft 2. The sliding groove 201 has a T-shaped cross-section and a sliding strip 3 is provided inside the sliding groove 201. The sliding strip 3 is slidably engaged with the sliding groove 201. The T-shaped sliding groove 201 and the sliding strip 3 are engaged to prevent the sliding strip 3 from disengaging from the sliding groove 201. A cavity is formed between the two ends of the sliding strip 3 along its length direction and the end of the sliding groove 201. The cavity facilitates the sliding of the sliding strip 3 along the length direction of the sliding groove 201. An elastic element 301, which is a spring, is provided at the end of the sliding strip 3.

[0023] Multiple stirring shafts 4 are provided on the outer side of the slide bar 3, and multiple blades 5 are provided on the stirring shafts 4. The blades 5 have a spiral structure. The rotating shaft 2 drives the stirring shafts 4 and the blades 5 to rotate, so as to mix the soil remediation agent and water in the mixing tank 1 evenly. The spiral structure of the blades 5 can agitate the liquid in different directions when the blades 5 rotate, which facilitates the rapid and even mixing of the remediation agent and water. When the water flow washes over the blades 5, it will push the slide bar 3 to slide along the slide groove 201. When the elastic element 301 touches the slide groove 201, the elastic force of the elastic element, i.e., the spring, can make the slide bar 3 move back and forth, thereby driving the blades 5 to move in the vertical direction. This allows the liquid in the mixing tank 1 to flow in multiple directions, thereby improving the mixing efficiency of the remediation agent and water.

[0024] In this application, a motor 6 is provided on the top of the mixing box 1. The output shaft of the motor 6 is connected to the rotating shaft 2, and the rotating shaft 2 is driven to rotate by the motor 6.

[0025] In this application, the bottom of the mixing tank 1 is a downwardly sloping arc-shaped concave surface, and a discharge port 102 is opened in the middle of the arc-shaped concave surface. An arc-shaped stirring rod assembly 7 is provided at the end of the rotating shaft 2. By setting the bottom of the mixing tank 1 to an arc-shaped concave surface, it is convenient for the liquid to flow to the discharge port 102, and at the same time, it is convenient for the arc-shaped stirring rod assembly 7 to stir the bottom of the mixing tank 1, preventing the repair agent from settling.

[0026] In this application, a plurality of connecting pipes 8 are provided through the top surface of the mixing tank 1. One end of the connecting pipe 8 extends into the mixing tank 1 and is connected to a nozzle. The plurality of connecting pipes 8 are used to connect external soil remediation agents. Through the cooperation of the connecting pipes 8 and the nozzle, the required different soil remediation agents and water are delivered into the mixing tank 1.

[0027] In this application, an adjustment vent 101 is provided on one side of the top surface of the mixing box 1. A valve is provided on the adjustment vent 101. The opening and closing of the adjustment vent 101 is controlled by the valve. During the preparation of the soil remediation agent mixture, the pressure inside the mixing box 1 can be adjusted by adjusting the vent 101.

[0028] In this application, a support frame 9 is provided at the bottom of the mixing box 1, and a temperature regulating cavity 103 is provided on the inner wall of the mixing box 1. A spiral tube is provided in the temperature regulating cavity 103, and the spiral tube is connected to an external water pipe. The temperature of the water in the water pipe is adjusted as needed, thereby achieving the purpose of controlling the internal temperature of the mixing box 1.

[0029] In one possible embodiment, a filter screen is installed inside the mixing tank 1 below the nozzle to filter the repair agent and remove impurities. The filter screen is movably connected to the cover of the mixing tank 1 for easy disassembly and replacement. A scraper can be connected to the outside of multiple stirring shafts on the same side. A telescopic rod is provided between the scraper and the stirring shaft to facilitate contact between the scraper and the inner wall of the mixing tank 1 for cleaning. This allows for the removal of residual agents adhering to the inner wall of the mixing tank 1 when mixing different agents next time. The telescopic rod is provided to adjust the distance between the scraper and the inner wall of the mixing tank 1 when cleaning is not required.

[0030] Working Principle: In use, the required soil remediation agent is connected to connecting pipe 8. The agent is then fed into mixing tank 1 via connecting pipe 8 and a nozzle. Water is introduced into mixing tank 1 through an inlet pipe. Motor 6 drives rotating shaft 2, which in turn drives stirring shaft 4 and blades 5 to mix the soil remediation agent and water evenly. Because blades 5 have a spiral structure, they agitate the liquid in different directions as they rotate. During agitation, the water flow impacts blades 5, causing slider 3 to slide along groove 201. When elastic element 301 contacts groove 201, its elasticity causes slider 3 to reciprocate, thus moving blades 5 vertically. This multi-directional flow of liquid within mixing tank 1 improves the mixing efficiency of the remediation agent and water.
