no. 1 approach

[0057] Refer to the picture: a resin treatment cylinder for soil available phosphorus detection, mainly including the following components: base cylinder 1, drain cap 2 and resin ball 3.

[0058] Wherein, the base cylinder 1 is a cylindrical structure with a closed bottom end and an open top end. The drain cover 2 is set on the top of the base tube 1, and the connection between the drain cover 2 and the base tube 1 can be: screwed on the base tube 1 through a thread structure or buckled on the base tube 1 through a buckle. Base cylinder 1 opening.

[0059] Wherein the end face of the draining cover 2 is provided with draining holes 2-1, and the draining holes 2-1 should be evenly distributed in a network shape, and its function is to discharge the liquid in the base cylinder 1. The resin ball 3 is freely arranged in the base cylinder 1 , that is to say, the resin ball 3 is placed in the base cylinder 1 and can roll in the base cylinder 1 . It should be noted that the size of...

no. 2 approach

[0069] As shown in the figure: a sample liquid preparation device for soil available phosphorus detection, which has: a soil sample processing component, the resin processing cylinder described in Example 1, and a resin regeneration processing component. The above-mentioned components are the core components of the sample liquid preparation device, not all components. It is foreseeable that at least it should include cabinets, intelligent control components (central processing unit, display screen, and operation buttons, etc.) and other necessary auxiliary accessories.

[0070]

[0071] The soil sample processing component is used for leaching and solid-liquid separation of soil samples, and the soil sample processing component has: an extraction cylinder 4, a filter plate 5, a first driving component and a second driving component.

[0072] Wherein, the extraction cylinder 4 is a cylindrical structure, the bottom end and the top end of the extraction cylinder 4 are all close...

Abstract

The invention discloses a resin treatment barrel for detecting available phosphorus in soil and a sample liquid preparation device. The resin treatment barrel is provided with a base barrel, a liquid draining cover and a resin ball. The sample liquid preparation device is provided with a soil sample treatment assembly used for extraction and solid-liquid separation of a soil sample, a resin treatment cylinder and a resin regeneration treatment assembly used for cleaning and regeneration treatment of resin balls. The resin regeneration treatment assembly comprises a cleaning part used for filling the resin treatment barrel with cleaning liquid and an acid leaching part used for filling the resin treatment barrel with acid soaking liquid. According to the invention, automatic preparation of the to-be-detected soil available phosphorus sample liquid can be realized, so that the working intensity of detection personnel is reduced, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for chemical analysis and determination, in particular to a resin treatment cylinder and a sample liquid preparation device for soil available phosphorus detection. Background technique [0002] Most of the phosphorus elements in plants are absorbed through the soil, but most of the phosphorus in the soil cannot be directly absorbed by plants, while the water-soluble phosphorus and weakly acid-soluble phosphorus in a small amount are easily absorbed and utilized by plants. Soil available phosphorus, also known as available phosphorus, is the phosphorus component in the soil that can be absorbed by plants, including all water-soluble phosphorus, some adsorbed phosphorus and organic phosphorus, and some soils also include some precipitated phosphorus. The determination of soil available phosphorus can understand the ability of the soil to supply phosphorus, which is of great significance...
