Description

Technical Field

[0001] This utility model relates to the field of soil treatment equipment technology, and in particular to a soil effective boron extraction device. Background Technology

[0002] In the field of soil nutrient testing, the extraction device is a key piece of equipment for obtaining effective components. First, the soil and the extractant are placed in the extraction bottle, and then the boron in the soil is released at high temperature. Because the soil is prone to clumping in the extraction bottle, it is necessary to manually shake it at regular intervals during operation. This is not only inconvenient to operate, but also only reduces the clumping phenomenon and cannot effectively break up the soil deposits, thus affecting the penetration of the extractant, resulting in a decrease in the dissolution rate of effective components and large deviations in the test results. Utility Model Content

[0003] The purpose of this invention is to provide an effective boron extraction device for soil, which can effectively break up soil deposits and clumps, and is easy to operate.

[0004] To achieve the above-mentioned objectives of this utility model, the soil effective boron extraction device adopts the following technical solution:

[0005] A soil effective boron extraction device includes a support frame with a water bath heating box above it. A support plate is fixed inside the water bath heating box, and a rotating disk is mounted above the support plate, rotatably connected to the support plate. The rotating disk has a rotating assembly for driving its rotation. Multiple elastic bases are evenly distributed along the circumference of the upper surface of the rotating disk, each elastic base for holding an extraction bottle. Multiple columns are arranged along the circumference of the edge of the rotating disk, with limit plates detachably mounted on the upper ends of the columns. The limit plates have through holes for the bottle necks to pass through. The extraction flask has a conical body and a cylindrical mouth. A retaining ring is detachably installed at the top of the mouth, and the outer diameter of the retaining ring is larger than the diameter of the through hole. A condenser tube is inserted into the mouth of the extraction flask. An elastic column is located at the center of the rotating disk. An upper connecting plate is detachably installed at the upper end of the elastic column, and the end of the upper connecting plate is fixedly connected to the upper end of the condenser tube by a clamp. A lower connecting plate is located at the lower end of the elastic column, and a mounting column is located on the inner side of the elastic base. The lower connecting plate and the mounting column are detachably connected.

[0006] Preferably, the elastic base includes a base body and a first spring. The base body has a placement groove for placing extraction bottles, the size of which is adapted to the extraction bottles. A mounting post is fixed to the base body, and the first spring is disposed between the base body and the rotating disk. The base body is slidably mounted on a sliding frame, which is vertically mounted on the rotating disk. The sliding frame has a vertically arranged sliding groove, and the base body has a sliding block that can be slidably mounted within the sliding groove. Under the action of the sliding groove, the extraction bottles can move vertically up and down.

[0007] Preferably, the elastic column includes a column body and a second spring. A sleeve is provided on the rotating disk, positioned below the lower connecting plate. The upper end of the column body passes through the lower connecting plate and the limiting plate, while the lower end extends into the sleeve. The second spring is located within the sleeve and positioned between the column body and the rotating disk. The condenser tube inserted into the bottle neck refluxes volatile components. When the base of the elastic base vibrates and moves up and down, the mounting column fixed inside it moves synchronously, driving the lower connecting plate, which is locked to it, to move up and down. The lower connecting plate forces the column body of the elastic column to compress or extend within the sleeve, and the column body buffers the vibration through the second spring. The upper end of the column body pushes the upper connecting plate to move, thereby achieving adaptive following of the condenser tube to the vibration of the extraction bottle through the clamp, effectively preventing the two from separating.

[0008] Preferably, the column and the limiting plate are connected by a first fastener, the mounting column and the lower connecting plate are connected by a second fastener, and the column body and the upper connecting plate are connected by a third fastener. The first fastener includes a first screw and a first nut. The first screw is provided at the top of the column, and the limiting plate has a first hole for the first screw to pass through. The first nut is threadedly engaged with the first screw for locking. The second fastener includes a second screw and a second nut. The second screw is provided at the top of the mounting column, and the lower connecting plate has a second hole for the second screw to pass through. The second nut is threadedly engaged with the second screw for locking. The third fastener includes a third screw and a third nut. The third screw is provided at the top of the column, and the upper connecting plate has a third hole for the third screw to pass through. The third nut is threadedly engaged with the third screw for locking. The use of screws and nuts for locking between the column and the limiting plate, between the mounting column and the lower connecting plate, and between the column body and the upper connecting plate enables quick disassembly and assembly without tools, significantly improving maintenance efficiency and equipment reusability.

[0009] Preferably, the mouth of the extraction bottle is threadedly connected to the retaining ring.

[0010] Preferably, the edge of the support plate is fixedly connected to the inner wall of the water bath heating box, and the support plate is provided with multiple flow holes. The flow holes promote heat convection within the water bath heating box, eliminate local temperature differences, ensure uniform heating of all extraction flasks, and guarantee consistent extraction reaction rates.

[0011] Preferably, the rotating assembly includes a motor disposed at the bottom of the support, the rotating disk is provided with a rotating shaft, the lower end of the rotating shaft extends out of the water bath heating box, and the output shaft of the motor is connected to the lower end of the rotating shaft.

[0012] Preferably, the lower end of the side wall of the water bath heating box is provided with a drain outlet.

[0013] Preferably, the bottom wall of the water bath heating box is provided with an electric heating wire.

[0014] Preferably, the extraction bottle has a first buffer layer at the bottle neck that can pass through a through hole, and a second buffer layer at the top of the bottle body. The first buffer layer and the second buffer layer are connected, and the diameter of the lower end of the second buffer layer is larger than the diameter of the through hole. The first buffer layer at the bottle neck passes through the through hole of the limiting plate, and the second buffer layer on the bottle body is locked in place to prevent detachment. This dual-stage buffering reduces rigid collisions between the extraction bottle and the metal parts, lowering the risk of breakage.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses a rotating disk to drive multiple extraction bottles to rotate at a uniform speed. Combined with the vertical floating degree of freedom provided by the elastic base, the soil inside the bottles is fully dispersed under the dual action of centrifugal force and vibration, which completely destroys the sediment and agglomerates. This significantly improves the penetration efficiency of the extractant and the dissolution rate of boron, thereby reducing detection deviation and ensuring data accuracy.

[0022] The specific working process and principle of this utility model are as follows: During operation, the extraction bottle 21 containing soil and extraction agent is placed in the placement groove of the elastic base, and then the limiting plate 12 is installed. The limiting plate 12 is installed on the column 20 by the first fastener. At this time, the bottle mouth 21a of the extraction bottle passes through the through hole 27 of the limiting plate 12 and the retaining ring 25 is tightened. Then, the condenser tube 6 is inserted into the bottle mouth and fixed to the upper connecting plate 10 by the clamp 7. After the extraction bottle 21 and the condenser tube 6 are installed, the motor 18 is started to drive the rotating disk 15 to rotate at a uniform speed. At the same time, water is added to the water bath heating box 5 and heated by the electric heating wire 19. The hot water flows from the flow hole 4 of the support plate 3 to the extraction bottle 21 to promote the dissolution of boron.

[0023] The rotation of the rotating disk 15 causes multiple extraction bottles 21 to move in a circular motion, generating centrifugal force to move the soil particles inside the bottles. At the same time, the seat 35 of the elastic base provides up-and-down vibration under the action of the first spring 34, thereby causing the extraction bottles 21 to vibrate up and down. The range of up-and-down movement of the conical bottle is between the retaining ring 25 and the second buffer layer 28. Therefore, the soil deposits and agglomerates can be broken up through the dual mechanical action of centrifugal force and vibration. Furthermore, the condenser tube 6 inserted into the bottle mouth refluxes volatile components. When the seat 35 of the elastic base vibrates and moves up and down, the mounting column 32 fixed inside it moves synchronously, driving the lower connecting plate 13 locked to it to move up and down. The lower connecting plate 13 forces the column 11 of the elastic column to compress or extend within the sleeve 14. The column 11 is buffered by the second spring 16. The upper end of the column 11 pushes the upper connecting plate 10 to move, thereby achieving adaptive following of the vibration of the extraction bottle 21 by the clamp 7, effectively preventing the two from separating.
