Description

Technical Field

[0001] The utility model belongs to the technical field of soil monitoring, in particular to an air dryer for soil monitoring samples. Background Art

[0002] Soil monitoring refers to the determination of various physical and chemical properties of soil, such as iron, manganese, total potassium, organic matter, total nitrogen, available phosphorus, total phosphorus, moisture, total arsenic, available boron, fluoride, chloride, mineral oil and total salt, by using appropriate determination methods, so as to achieve the purpose of monitoring the current status of soil quality; monitoring soil pollution accidents; dynamic monitoring of land treatment of pollutants; soil background value investigation, etc. When soil is collected, the soil usually contains a certain amount of moisture, and the moisture content of the soil often affects the monitoring results of the soil. Therefore, an air dryer is needed before monitoring to dry the soil through airflow, so that the monitoring equipment can quickly monitor the soil samples and improve the processing efficiency. However, it still has the following disadvantages in actual use:

[0003] The utility model with publication number CN216847132U discloses a soil monitoring sample air-drying device, wherein a driving box is fixedly connected to the bottom of the inner cavity of the box, a frame is slidably connected to the top of the driving box, a bearing frame is placed in the inner cavity of the frame, the outer surface of the bearing frame is tightly fitted with the inner surface of the frame, and a rotating motor is fixedly connected to the bottom of the inner cavity of the driving box through a support plate. After the soil is placed in the air-drying device for air-drying, a small amount of soil often remains in the bearing structure, which needs to be cleaned in time before another portion of soil can be air-dried to avoid affecting the monitoring result of the next portion of soil, which is time-consuming and labor-intensive.

[0004] When monitoring the soil, it is usually necessary to collect multiple soil samples for monitoring, so the multiple soil samples need to be air-dried. After the soil is collected, the soil needs to be poured out of the collection device, placed in an inverted air dryer for processing, and then sent to the detection device for detection. This operation is time-consuming and labor-intensive. Utility Model Content

Through an air drying box, a support frame and a collecting tube, the utility model solves the problem that the bearing structure of the air dryer needs to be cleaned after each air drying process on the soil, which affects the processing speed. In addition, soil monitoring requires the collection of a large number of samples at the same time. After collection, the samples need to be poured from the collecting device into the air dryer and then inverted for detection by the detection device after air drying, which is time-consuming and laborious.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

The slide block is slidably connected to the inner side of the slide groove, and a plurality of the limiting holes are suspended on the top of a plurality of sealing plates.

[0014] A plurality of limiting holes can be plugged into a plurality of collecting tubes at the same time, so that the air dryer can perform air drying treatment on a plurality of soil samples at the same time, thereby improving the treatment efficiency.

[0015] Furthermore, a first threaded tube is clamped and fixed on the top of the collecting tube, a counterweight is clamped and fixed on the bottom edge of the one-way valve, the collecting tube is inserted through the top of the limiting hole, and the counterweight is attached to the upper side of the sealing plate;

[0016] The counterweight block can ensure that when the electromagnet adsorbs all the adsorption plates, the weight of the counterweight block can ensure that the collection tube is stably inserted into the limit hole. The staff inserts the collection tube filled with soil into the limit hole and dries it through an air drying box. After drying, the collection tube can be directly taken out and transported to the detection device for detection, and the air drying box can quickly dry the next batch of soil. The operation is simple and convenient, and there is no need to clean the air drying box before filling the next soil sample.

[0018] The air enters the hopper through the pressure valve, and the air cools and dries the soil when passing through the supporting mesh pipe, and then is discharged through the one-way valve. The supporting mesh pipe can support the soil so that the soil will not be discharged from the collection pipe with the air flow and cause pollution to the air drying box.

[0019] The utility model has the following beneficial effects:

[0020] The utility model solves the problem that after the soil is placed in the air-drying device for air-drying treatment, a small amount of soil often remains in the bearing structure, and it needs to be cleaned in time before another portion of soil can be air-dried to avoid affecting the monitoring result of the next portion of soil, which is time-consuming and laborious. After a certain amount of soil samples are collected, the collection tubes for placing multiple soil samples are placed inside the air-drying box for air-drying treatment, and air enters the hopper through a pressure valve. When the air passes through the supporting mesh pipe, the soil is air-cooled and dried, and then discharged through the one-way valve. The supporting mesh pipe can support the soil, so that the soil will not be discharged from the collection pipe with the airflow to pollute the air-drying box, and there is no need to clean the air-drying box before filling the next portion of soil sample. At the same time, a large number of collection tubes can be uniformly cleaned after all soil samples are monitored, thereby improving the processing efficiency.

[0021] The utility model solves the problem that, when monitoring the soil, it is usually necessary to collect multiple soil samples for monitoring, and thus the multiple soil samples need to be air-dried.
