Abstract

The utility model discloses a soil alkaline hydrolysis nitrogen diffusion dish which comprises a diffusion dish and a diffusion dish cover, wherein an inner ring wall is arranged in the diffusion dish and adopts a conical structure; a groove is formed in the outer ring wall of the diffusion dish; the edge of the diffusion dish cover can be embedded into the groove. Due to adoption of the conical structure of the inner ring wall of the diffusion dish, the situation that a liquid on the outer side of the inner ring wall flows to the inner side of the inner ring wall because of maloperation or excessive vibration is effectively avoided; due to adoption of a handle arranged on the diffusion dish cover, the cover can be closed or taken out conveniently; the contact surface between the groove and the diffusion dish cover adopts a conical surface structure and is made of a frosted glass material, so that sealing between the diffusion dish and the diffusion dish cover is well realized. By adopting the diffusion dish, liquid pollution caused when a dish edge and frosted glass are rotated for being glued is effectively prevented, the experiment precision is improved, the re-doing rate is reduced, a procedure of boiling alkali glue is canceled, the structure is simple, the operation and washing are easy, and the technical requirements are low.

Description

A kind of diffusion boat of soil alkaline hydrolyzable nitrogen
Technical field
The utility model relates to a kind of diffusion boat of soil alkaline hydrolyzable nitrogen, belongs to experiment equipment technical field.
Background technology
At present, soil alkaline hydrolyzable nitrogen determination method: take wind desiceted soil, it is placed in to diffusion boat mistress equably, get 2% boric acid indicator solution and be put in chamber in diffusion boat, then coat alkaline glue at diffusion boat mistress edge, cover frosted glass, rotation for several times, makes ware limit and frosted glass completely bonding.Gradually turn-off frosted glass, makes diffusion boat mistress expose a slit on one side again, adds rapidly sodium hydroxide solution, cover tightly immediately, tighter with bungee circle, frosted glass is fixed, shake gently diffusion boat, alkali lye is fully mixed with soil.In operating process, prepare alkaline glue and be coated with alkaline glue at mistress edge, make experimental implementation loaded down with trivial details, glue coats rear ware limit and frosted glass plate rotation easily makes the contaminated aqueous solution in diffusion boat for several times, rework rate is high, high to operating personnel's technical merit requirement, affects work efficiency.
Summary of the invention
The purpose of this utility model is: the diffusion boat that a kind of practicality, convenience, succinct soil alkaline hydrolyzable nitrogen are provided, it can save the process of preparing alkaline glue, ware limit gluing, thereby can avoid causing liquid contamination in gluing process, to overcome the deficiencies in the prior art.
The technical solution of the utility model
A diffusion boat for soil alkaline hydrolyzable nitrogen, comprises diffusion boat and diffusion boat lid, is provided with internal ring wall in diffusion boat, and internal ring wall is pyramidal structure, on the external annulus of diffusion boat, is provided with groove, and diffusion boat cover rim limit can embed in groove.
In the diffusion boat of aforesaid soil alkaline hydrolyzable nitrogen, groove and diffusion boat lid contact site adopt glass frosted material to form.
In the diffusion boat of aforesaid soil alkaline hydrolyzable nitrogen, be provided with handle at diffusion boat tops.
In the diffusion boat of aforesaid soil alkaline hydrolyzable nitrogen, the surface of contact of described groove and diffusion boat lid is the conical surface.
Owing to adopting technique scheme, compared with prior art, the pyramidal structure of internal ring wall of the present utility model, can effectively prevent from because of misoperation or shake the too quickly liquid that causes internal ring wall outside flowing into internal ring wall inner side; By covering and be provided with handle at diffusion boat, facilitate covering tightly or taking out of lid, the surface of contact of groove and diffusion boat lid is that cone structure and this face are made up of glass frosted material, the fine sealing that realizes diffusion boat and diffusion boat lid of energy, the utility model can effectively prevent that ware limit and frosted glass from causing liquid contamination in gluing rotary course, improve experimental precision, reduced rework rate; Saved the operation that boils alkaline glue, simple in structure, easily, technical requirement is low for operation and cleaning.
