Description

Technical Field

[0001] The invention belongs to the technical field of soil analysis devices, and in particular relates to a pre-treatment device for analyzing soil in species habitats. Background Art

[0002] In recent years, a series of habitat ecological and environmental problems caused by environmental pollution have seriously affected the survival and development of wild species. Soil remediation is a technical measure to restore the normal function of polluted soil. According to the pollution situation of the habitat, physical, chemical and biological methods are used to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to transform toxic and harmful pollutants into harmless substances. Among them, the pollution situation of the habitat is determined based on the soil analysis results of the polluted area of ​​the habitat by scientific researchers.

[0003] Soil analysis is a qualitative and quantitative determination of the composition and physical and chemical properties of soil. However, some impurities in the soil are not pollutants, but will affect the soil analysis process and results, such as obvious domestic garbage and large stones. In addition, traditional soil analysis devices need to soak and extract the soil to analyze the soil. The amount of extractant used is too large, and the soaking time is long, which leads to a slow soil analysis process. Therefore, we provide a pre-treatment device for species habitat soil analysis. Summary of the invention

[0004] In order to solve the above problems, the primary purpose of the present invention is to provide a pre-treatment device for soil analysis of species habitats.

[0005] The above purpose is achieved by the following preparation process:

[0006] The present invention provides a pretreatment device for species habitat soil analysis, comprising a shell and a sample inlet and a sample outlet located on the shell, wherein the shell is provided with an extract inlet pipe, a separation net cylinder, a grinding assembly, an extract separation assembly and a liquid storage tank in sequence from top to bottom, one end of the separation net cylinder is rotatably connected to the inner wall of the shell, the sample inlet is communicated with the separation net cylinder, the sample outlet is arranged at one end of the liquid storage tank, and the separation net cylinder and the grinding assembly share a set of driving mechanisms;

[0007] When the pretreatment device performs soil pretreatment, the soil to be treated enters the rotating separation net cylinder from the sampling port to separate impurities and soil. At the same time, the extract is sprayed downward from the extract inlet pipe. The extract and soil enter the grinding component to be fully mixed and then fall into the extract separation component for solid-liquid separation. The liquid required for soil analysis falls into the liquid storage tank and is then discharged from the sampling port.

[0008] As a further improvement of the above technical solution, the separation net cylinder includes a cylinder body and a drawer plate clamped on the cylinder body, the cylinder body and the drawer plate form a cylinder as a whole, a movable plate is provided under the injection port, the curvature of the movable plate is greater than the curvature of the drawer plate, when the drawer plate rotates to the movable plate area, the movable plate is opened to draw the drawer plate away from the cylinder body.

[0009] As a further improvement of the above technical solution, a screen is provided between the separation net cylinder and the grinding assembly, and inspection doors are provided at both ends of the screen, and the screen is slidably arranged in the shell.

[0010] As a further improvement of the above technical solution, the grinding assembly includes a rotating shaft, a plurality of rotating disks fixedly arranged on the rotating shaft, a fixed disk slidably mounted on the rotating shaft and matching the rotating disk, and two limiting rods symmetrical to each other and passing through all the fixed disks. Both ends of the limiting rods are provided with spring cylinders for enabling the limiting rods to be extended and retracted in the horizontal direction. When the rotating shaft drives the rotating disk to rotate, the rotating disk and the fixed disk are in an intermittent opening and closing state, so that the extract and soil entering between the rotating disk and the fixed disk can be fully mixed.

[0011] As a further improvement of the above technical solution, a protrusion is provided on the rotating disk, an annular groove is provided on the fixed disk at a position overlapping with the protrusion, and a protrusion is provided in one section of the annular groove, and the limiting rod is located outside the annular groove.

[0012] As a further improvement of the above technical solution, the protrusion on the rotating disk slides in the annular groove of the fixed disk, and the rotating disk and the fixed disk overlap at this time, so that the extract and soil entering between the rotating disk and the fixed disk can be fully mixed. When the protrusion rotates to the protrusion on the annular groove, the rotating disk and the fixed disk are separated, and the extract and soil mixture falls.

[0013] As a further improvement of the above technical solution, the grinding assembly is provided with two levels, and the rotating disks and fixed disks of the upper and lower levels are staggered as a whole.

[0014] As a further improvement of the above technical solution, the driving mechanism includes a servo motor, a driving wheel located at the output shaft end of the servo motor and connected to the driving end of the separation net cylinder, a driven wheel located at the driving end of the rotating shaft of the grinding assembly, and a transmission member that uses the driving wheel to drive the driven wheel to rotate.

[0015] As a further improvement of the above technical solution, the extract separation component includes a liquid collection tray slidably arranged in the shell and a plurality of overflow pipes evenly distributed on the liquid collection tray, and an overflow net and a protective cover are provided at the upper end of each overflow pipe.

[0016] The beneficial effects of the present invention are:

[0017] (1) The separation net cylinder provided in the present invention requires corresponding pre-treatment before soil analysis to remove impurities in the soil that may affect the analysis;

[0018] (2) The present invention uses a grinding assembly to fully grind the extract and soil, especially some agglomerated soil blocks, so that the extract and soil can be fully mixed. On the premise of ensuring that the soil is fully extracted, the use of the extract is reduced, the soaking time is reduced or omitted, and the speed of soil analysis is accelerated;

[0019] (3) The present invention uses the principle of sand sedimentation to naturally separate the extracted liquid and sand through the set extraction liquid separation component to obtain the liquid required for soil analysis;

[0020] (4) The present invention arranges the extracting liquid inlet pipe, the separation net cylinder, and the grinding assembly in the housing in order from top to bottom. On the one hand, the flushing force of the extracting liquid is used to avoid soil residue in the separation net cylinder and the grinding assembly. On the other hand, the extracting liquid is broken into continuous droplets through the separation net cylinder, which can be better mixed with the soil to prevent soil agglomeration. At the same time, it is also convenient to clean the separation net cylinder and the grinding assembly inside the housing later. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1 As shown, the pretreatment device for species habitat soil analysis of this embodiment includes a shell 1 and an inlet 2 and an outlet 8 located on the shell 1. The shell 1 is provided with an extract inlet pipe 3, a separation net tube 4, a grinding assembly 5, an extract separation assembly 6 and a liquid storage tank 7 from top to bottom. One end of the separation net tube 4 is rotatably connected to the inner wall of the shell 1. An annular boss is provided on the inner wall of the shell 1, and a groove is provided at the front end of the annular boss. One end of the separation net tube 4 is engaged with the groove. When the separation net tube 4 rotates, one end of the separation net tube 4 rotates in the groove. The inlet 2 is connected to the separation net tube 4, so that the soil to be treated directly enters the interior of the separation net tube 4. The outlet 8 is provided at one end of the liquid storage tank 7.

[0031] When the pre-treatment device performs soil pre-treatment, the following steps are included:

[0032] 1. Put the soil to be treated from the sample inlet 2 into the rotating separation net cylinder 4, and separate the large impurities (garbage and large stones) from the soil by centrifugal force. At the same time, the extract is sprayed downward from the extract inlet pipe 3, pre-mixed with the soil, and the soil and extract mixture falls from the separation net cylinder 4;

[0033] 2. After the soil and extract mixture falls, it enters the grinding component 5 for grinding, so that the extract and soil are fully mixed, and then falls into the extract separation component 6 for precipitation and soaking. After reaching a certain liquid level, solid-liquid separation is automatically performed. The liquid required for soil analysis falls into the liquid storage tank 7 and is then discharged from the sample outlet 8 to the soil analysis process.

[0034] like Figure 4As shown, the extract separation assembly 6 includes a liquid collection tray 601 slidably arranged in the housing 1 and a plurality of overflow pipes 602 evenly distributed on the liquid collection tray 601. Each overflow pipe 602 is provided with an overflow net 603 and a protective cover 604 at the upper end. The protective cover 604 prevents objects from falling directly into the overflow pipe 602. Inspection doors are provided at both ends of the liquid collection tray 601, so that the internal conditions of the liquid collection tray 601 can be observed at any time. When the soil and extract mixture ground by the grinding assembly 5 falls into the liquid collection tray 601, it first falls on the liquid collection tray 601. During the process of slowly accumulating, the extract can soak the soil to obtain further extraction. When the liquid level is greater than the height of the overflow pipe 602, the extract overflows downward along the overflow pipe 602 to the liquid storage tank 7 for storage. When the sediment in the liquid collection tray 601 is observed to accumulate to the upper limit from the inspection door, the inspection door is opened, the liquid collection tray 601 is slid out along the housing 1, and the sediment is processed in the next step.

[0035] Example 2

[0036] Based on the above embodiments, as preferred, Figure 2 As shown, the grinding assembly 5 includes a rotating shaft 501, a plurality of rotating disks 502 fixedly arranged on the rotating shaft 501, a fixed disk 503 slidably mounted on the rotating shaft 501 and matching with the rotating disk 502, and two symmetrical limiting rods 504 passing through all the fixed disks 503, and both ends of the limiting rod 504 are provided with a spring cylinder 505 for enabling the limiting rod 504 to be extended and retracted in the horizontal direction, as shown in FIG. Figure 3 As shown, a protrusion 5021 is provided on the rotating disk 502 , an annular groove 5031 is provided on the fixed disk 503 at a position overlapping with the protrusion 5021 , and a protrusion 5032 is provided in one section of the annular groove 5031 , and the limiting rod 504 is located outside the annular groove 5031 . When the rotating shaft 501 drives the rotating disk 502 to rotate, the rotating disk 502 and the fixed disk 503 are in an intermittent disconnection state, and the protrusion 5021 on the rotating disk 502 slides in the annular groove 5031 of the fixed disk 503. At this time, the rotating disk 502 and the fixed disk 503 overlap, so that the extract and soil entering between the rotating disk 502 and the fixed disk 503 can be fully mixed. When the protrusion 5021 rotates to the protrusion 5032 on the annular groove 5031, the rotating disk 502 and the fixed disk 503 are separated, and the fixed disk 503 drives the limiting rod 504 and the spring cylinder 505 to move in the horizontal direction, and the extract and soil mixture falls from the gap generated by the separation of the rotating disk 502 and the fixed disk 503 due to gravity.

[0037] The grinding assembly 5 of this embodiment is provided with two stages, and the rotating disks 502 and the fixed disks 503 of the upper and lower stages are staggered as a whole to prevent insufficient grinding of the first-stage grinding assembly 5.

[0038] Example 3

[0039] On the basis of Example 1 and Example 2, as preferred, Figure 1 As shown, the separation net cylinder 4 and the grinding assembly 5 share a set of driving mechanisms, which include a servo motor 11, a driving wheel 12 located at the output shaft end of the servo motor 11 and connected to the driving end of the separation net cylinder 4, a driven wheel 14 located at the driving end of the rotating shaft 501 of the grinding assembly 5, and a transmission member 13 that uses the driving wheel 12 to drive the driven wheel 14 to rotate. The output shaft end of the servo motor 11 is connected to the driving wheel 12, and the other end of the driving wheel 12 is connected to the driving end of the separation net cylinder 4. The rotation of the servo motor 11 drives the separation net cylinder 4 to rotate. The driving wheel 12 and the driven wheel 14 are connected through the transmission member 13. The driven wheel 14 drives the rotating shaft 501 of the grinding assembly 5 to rotate to realize the grinding process.

[0040] Among them, the driving wheel 12 and the driven wheel 14 include but are not limited to any mechanical parts that can realize transmission connection, such as gears and sprockets, and the transmission parts 13 include but are not limited to any mechanical parts that can realize power transmission, such as belts, chains, racks, etc.

[0041] Example 4

[0042] Based on the above embodiments, as preferred, Figure 1 As shown, a screen 10 is provided between the separation net cylinder 4 and the grinding assembly 5, and inspection doors are provided at both ends of the screen 10. The screen 10 is slidably arranged in the shell 1 for easy removal. At the same time, when the soil and the extract are lowered, they can be further crushed to increase the contact area, which is beneficial to the mixing of the two.

[0043] like Figure 5-6 As shown, the separation net cylinder 4 includes a cylinder 401 and a drawer plate 402 clamped on the cylinder 401, the cylinder 401 and the drawer plate 402 form a cylinder as a whole, one end of the cylinder 401 and the drawer plate 402 are embedded in the groove on the surface of the annular boss on the inner wall of the shell 1, and a movable plate 9 is provided below the cylinder 401 and the drawer plate 402. The groove is connected to the movable plate 9 area, and the curvature of the movable plate 9 is greater than the curvature of the drawer plate 402. After the current processing device is finished, the drawer plate 402 is rotated to the movable plate 9 area, and the movable plate 9 is opened to pull the drawer plate 402 away from the cylinder 401. At this time, the impurities in the cylinder 401 fall onto the screen 10. After observation through the inspection door, the inspection door is opened to slide the screen 10 out along the shell 1, and the impurities are processed in the next step.

[0044] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
