Description

Technical Field

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

[0002] In the soil element determination test, when determining certain elements, the soil sample needs to be burned to make it pyrolyzed at high temperature. Usually, the soil sample is spread flat on the bottom of the sample boat, and then sent to the burning furnace for heating and subsequent testing. After the test is completed, the sample boat needs to be cleaned before it is put into use. The sample boat usually uses a metal box body, and the inner wall surface becomes rough after long-term use. It is easy for local samples to sinter on the inner wall of the sample boat after high-temperature burning, making it difficult to clean. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a soil testing sample accommodating device, which forms a slight gap between the sample and the device after the test is completed, so as to facilitate cleaning after use.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a soil testing sample accommodating device, comprising a device body, an inner wall of the device body is provided with an anti-sticking layer, and a temperature-sensitive elastic layer is sandwiched between the anti-sticking layer and the inner wall surface of the device body.

[0005] Furthermore, the device body is configured as a groove body, the anti-sticking layer includes a plurality of anti-sticking units, and the plurality of anti-sticking units are respectively configured corresponding to a plurality of groove wall surfaces of the device body.

[0006] Furthermore, the temperature-sensitive elastic layer includes an elastic body and a plurality of temperature-sensitive expansion and contraction units, and the plurality of temperature-sensitive expansion and contraction units are distributed in the elastic body.

[0007] Furthermore, the elastic body is sandwiched between the joint surfaces of adjacent anti-sticking units.

[0008] Furthermore, the anti-sticking layer is made of a highly wear-resistant material.

[0009] Furthermore, the elastomer is an elastic structural layer formed by solidifying an adhesive, and the temperature-sensitive expansion and contraction unit is an air cavity structure built into the elastic structural layer.

[0010] Beneficial effects: The utility model provides a soil testing sample accommodating device, which relatively isolates the inner wall of the accommodating groove and the soil sample through a wear-resistant and smooth anti-sticking layer, and utilizes the temperature increase during the burning process so that the edge layer of the sample is elastically squeezed by the anti-sticking layer, making the edge mud layer relatively compact. After cooling, a slight gap is formed between the sample and the anti-sticking layer, reducing the adhesion of the sample to the groove wall, facilitating the separation of the sample from the groove body, and facilitating quick and easy cleaning.

[0012] Attached Figure 2 It is a partial cross-sectional schematic diagram of an embodiment of the utility model. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings.

[0014] As attached Figure 1-2 The soil detection sample accommodating device comprises a device body 1 , an anti-sticking layer 2 is arranged on the inner wall of the device body 1 , and a temperature-sensitive elastic layer 3 is sandwiched between the anti-sticking layer 2 and the inner wall surface of the device body 1 .

[0015] This solution uses an anti-sticking layer to isolate the soil sample from the inner wall of the device to avoid sintering that is difficult to clean. The temperature-sensitive elastic layer is used to sense temperature changes and produce corresponding elastic deformation. When high-temperature burning is performed, thermal expansion occurs. The slight expansion pushes the anti-sticking layer to squeeze the internal soil sample. Due to the small expansion difference, only the part of the soil layer close to the anti-sticking layer is squeezed. Since the anti-sticking layer is not easy to adhere to the soil sample, under the squeezing effect, the outer layer of the soil sample is more tightly adhered to the inner layer of the soil sample. When the temperature drops after the test, the temperature-sensitive elastic layer contracts, driving the anti-sticking layer to move slightly away from the soil sample. Since the adhesion force of the inner layer of the soil sample to the outer layer of the soil sample is greater than the adhesion force of the anti-sticking layer to the outer layer of the soil sample, the outer layer of the soil sample is separated from the anti-sticking layer to form a slight gap, which reduces the adhesion of the sample to the slot wall, facilitates the separation of the sample from the slot body, and is easy and quick to clean.

[0016] The device body 1 is configured as a slot body, the anti-adhesive layer 2 includes a plurality of anti-adhesive units 21, and the plurality of anti-adhesive units 21 are respectively configured corresponding to the plurality of slot walls of the device body 1. The temperature-sensitive elastic layer 3 includes an elastic body 31 and a plurality of temperature-sensitive expansion and contraction units 32, and the plurality of temperature-sensitive expansion and contraction units 32 are distributed in the elastic body 31.

[0017] It can be applied to the soil mercury test, and is set to the original sample boat structure size. The anti-sticking layer is composed of multiple anti-sticking units, which can enable each unit to move independently, avoiding excessive stress inside the anti-sticking layer due to the multi-directional expansion direction, thereby increasing the service life of the anti-sticking layer. The temperature-sensitive expansion and contraction unit refers to a structure that can expand and contract under the influence of temperature, which is confined in the elastic body and evenly distributed; the external trough adopts a metal structure, which can cooperate with the elastic body to constrain its thermal expansion direction and provide a certain elastic space, so that the thrust generated by the thermal expansion acts evenly on the corresponding anti-sticking unit, achieving the purpose of gathering and squeezing the edge of the soil sample inward.

[0018] Preferably, the elastic body 31 is sandwiched between the joint surfaces of the adjacent anti-adhesion units 21, which can provide an elastic range for the relative movement between the two adjacent anti-adhesion units and play a certain sealing role to prevent the soil sample from entering the gap of the anti-adhesion unit, thereby avoiding the formation of residues that affect the test results.

[0019] Embodiment: The anti-sticking layer 2 is made of a highly wear-resistant material. Preferably, the anti-sticking layer is made of highly wear-resistant ceramic sheets. The elastomer 31 is an elastic structure layer formed by solidifying an adhesive, and the temperature-sensing expansion and contraction unit 32 is an air cavity structure built into the elastic structure layer.

[0020] In practical applications, a ceramic sheet can be bonded to the inner wall of the sample boat based on the original sample boat. The sample boat and the ceramic sheet can be firmly connected by using a high temperature resistant resin adhesive as an adhesive, and a certain elasticity can be provided. Evenly distributed grooves are provided on the bonding surface of the ceramic sheet to facilitate the formation of evenly distributed tiny bubbles in the bonding surface, so that when burned at high temperature, the ceramic sheet is pushed to move by the thermal expansion of the air in the bubbles.

[0021] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
