Description

Technical Field

[0001] The utility model relates to the technical field of soil pollution detection, in particular to a soil pollution detection liquid extraction device. Background Art

[0002] With the acceleration of industrialization and the increasing frequency of agricultural activities, soil pollution has become increasingly prominent, posing a serious threat to the ecological environment and human health. Soil pollution leads to a decline in soil quality and affects crop yield and quality. Therefore, it is particularly important to accurately and quickly detect and evaluate soil pollution. The soil pollution detection liquid extraction device came into being and became an important tool for solving the problem of soil pollution detection. The device can efficiently extract pollutants from the soil and provide reliable samples for subsequent pollution detection and evaluation. Its working principle is mainly based on physical and chemical principles. Through specific extraction agents and operating methods, pollutants in the soil are separated to form liquid samples for analysis.

[0003] For example, the Chinese authorized patent "A soil pollution detection liquid extraction device" with announcement number CN220367300U includes an extraction cylinder, a flushing filter box and a lifting assembly; the extraction cylinder is used to hold the extraction liquid and use the extraction liquid to extract the polluted components from the soil to be tested; the flushing filter box is used to hold the soil to be tested, and the flushing filter box is installed on the inner wall of the extraction cylinder by sliding up and down; the lifting assembly is connected to the flushing filter box in a transmission manner, and the lifting assembly is used to drive the flushing filter box to move up and down in the extraction liquid. The reciprocating lifting of the flushing filter box can make the soil to be tested fully contact with the extraction liquid, so that the extraction liquid can fully extract the pollutants and obtain the detection liquid, and the upper clear liquid can be taken out in conjunction with the detection liquid valve.

[0004] Although the above-mentioned existing technology can realize the extraction of soil detection liquid, the extraction method is relatively complicated and cannot quickly separate the soil and the extraction liquid in one test, which not only affects the detection efficiency but also creates a burden for subsequent cleaning. Therefore, it does not meet the existing needs. In this regard, we propose a soil pollution detection liquid extraction device. Utility Model Content

[0005] The purpose of the utility model is to provide a soil pollution detection liquid extraction device to solve the problem that the soil pollution detection liquid extraction device proposed in the above background technology cannot quickly separate the soil and the extraction liquid in one detection.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil pollution detection liquid extraction device, comprising a mounting frame, a crushing cylinder is installed inside the mounting frame, and the crushing cylinder is fixed to the mounting frame, and a stirring and conveying cylinder is arranged below the crushing cylinder; and further comprising:

[0007] A conical mesh cylinder is arranged at one end of the stirring and conveying cylinder, and the conical mesh cylinder is connected with the stirring and conveying cylinder. A rotating shaft is rotatably installed inside the stirring and conveying cylinder, and the rotating shaft extends to the inside of the conical mesh cylinder. A spiral conveying blade is welded and fixed to the outside of the rotating shaft, and a plurality of spiral conveying blades are arranged;

[0008] An infusion ring, which is arranged outside the stirring and conveying cylinder, and a nozzle is installed inside the infusion ring, and the nozzle extends to the inside of the stirring and conveying cylinder;

[0009] The collecting box is arranged outside the conical mesh cylinder, and a drainage pipe is installed at the bottom of the collecting box.

[0010] Preferably, a driving seat is installed inside the crushing barrel, a driving shaft is rotatably installed inside the driving seat, active bevel gears are fixedly installed on both sides of the outside of the driving shaft, crushing knives are rotatably installed on both sides above the driving seat, a driven bevel gear is installed on the shaft at the bottom of the crushing knife, and the driven bevel gear is meshed with the active bevel gear, a first motor is installed below one side of the crushing barrel, and the output shaft of the first motor is fixed to the driving shaft.

[0011] Preferably, a dust hood is installed at the upper end of the other side of the crushing cylinder, and the dust hood is limited on the inner wall of the crushing cylinder, a dust collecting box is installed on one side of the dust hood, and a negative pressure fan is installed on one side of the dust collecting box.

[0012] Preferably, a liquid guiding groove is provided at the bottom of the inner cavity of the collecting box, and the liquid guiding groove is in an inclined structure, an extrusion plate is provided on one side of the inner cavity of the collecting box, and a mud discharge port is provided below the extrusion plate.

[0013] Preferably, the diameter of the conical mesh cylinder gradually decreases from one end close to the stirring and conveying cylinder to the other end, and the adjacent diameters of the spiral conveying blades inside the conical mesh cylinder gradually decrease from one end close to the stirring and conveying cylinder to the other end.

[0014] Preferably, the infusion rings are connected by an infusion tube, and one end of the infusion tube is connected to the extractant storage tank.

[0015] Preferably, a second motor is fixedly mounted on the other end of the stirring and conveying cylinder, and the output shaft of the second motor is fixed to the rotating shaft via a coupling.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model is provided with a crushing cylinder, and the sampled soil is poured into the inside from the addition port at the top. By turning on the first motor, its output shaft drives the driving shaft to rotate at a high speed, thereby driving the active bevel gear to rotate. Under the friction between the active bevel gear and the driven bevel gear, the shaft at the bottom of the crushing knife is driven to rotate, forming a high-speed rotation of the crushing knife. Then, when the soil entering the crushing cylinder contacts the crushing knife, it can be quickly broken up, thereby avoiding the occurrence of caking. This mechanism can keep the soil to be tested in a loose state, thereby facilitating full contact with the extractant and improving the detection accuracy.

[0018] 2. The utility model is provided with a stirring and conveying cylinder. By turning on the second motor, its output shaft drives the rotating shaft equipped with spiral conveying blades to rotate. The scattered soil enters the stirring and conveying cylinder through the connecting pipe and moves to one side under the push of the spiral conveying blades. During the movement, the pump is turned on to convey the extractant in the extractant storage tank to the infusion ring through the conveying pipe, and enters the interior of the stirring and conveying cylinder through the nozzle to form contact with the soil. At the same time, the spiral conveying blades are used to stir the soil, so that the extractant is fully mixed with the soil. Finally, the soil containing the extractant enters the conical mesh cylinder. As the diameter of the inner cavity gradually shrinks, the spacing between adjacent spiral conveying blades also gradually decreases, so the soil is continuously squeezed. At this time, the extract can be separated from the soil and enter the collection box through the conical mesh cylinder, which is convenient for the staff to collect it in a centralized manner. After the soil loses moisture, it is discharged in a solid state at the outlet, so that the staff can handle it independently. The stirring and conveying cylinder can complete the transportation, injection, stirring and separation of the soil at one time, which not only reduces the difficulty of operation, but also quickly realizes the collection of the extract, providing a guarantee for efficient detection work.

During the movement, the pump is turned on to convey the extractant in the extractant storage tank to the infusion ring 22 through the conveying pipe, and enters the interior of the stirring and conveying cylinder 3 through the nozzle 23 to form contact with the soil.
