Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0012] Such as figure 1 Shown: the present invention discloses a kind of digital proportional accurate rapid mixing fertilizer acid-base control liquid level device, which comprises:

[0013] The upper cover, the main body of the splash-proof tube, the splash-proof interlayer, the gas outlet cover, the large and small sealing rings, and the conduit. It includes a main body of the splash tube, an upper cover and a bottom sealing ring which are detachably arranged on the upper part of the main body of the splash tube. The upper cover is provided with an air outlet cover, an air inlet, and an air outlet. The air outlet cover is located at the connection between the upper cover and the main body of the splash-proof tube. The lower part of the main body of the splash-proof tube is provided with an anti-splash interlayer. The conduit runs...

Abstract

The invention relates to the field of a splash-proof tube for an azotometer, in particular to a splash-proof tube device for a fully automatic azotometer. The splash-proof tube device comprises a splash-proof tube main body, an upper cover detachably arranged at the upper part of the splash-proof tube main body and a bottom seal ring, wherein a gas outlet cover, a gas inlet and a gas outlet are formed in the upper cover; the gas outlet cover is located at the joint of the upper cover and the splash-proof tube main body; a splash-proof interlayer is arranged at the lower part of the splash-proof tube main body; the lower end of the gas inlet is communicated with a guide tube, and the guide tube penetrates through the splash-proof interlayer and penetrates to the outside of the bottom seal ring. The upper cover and the splash-proof tube main body are connected through a 360-degree mounting hole and rotate freely in 360 degrees foreach stage of mounting every 45 degrees; a seal ring is arranged at the bottom of the gas outlet cover; the guide tube is provided withtwo liquid charging ports on the splash-proof interlayer, and the liquid charging ports are communicated withambient pressure; casings of the splash-proof tube main body and the upper cover are both prepared from double-layer modified polypropylene through one-step molding.

Description

technical field [0001] The invention relates to the field of an anti-splash tube of an azotometer, in particular to a fully automatic anti-splash tube device for an azotometer. Background technique [0002] The anti-splash tube of the azotometer is mostly made of glass products in the existing environment, and it is easy to break under high temperature and high pressure. It is not strong in corrosion resistance to liquids or gases with strong acids and alkalis, and needs to be replaced frequently, which is troublesome to operate. Our product uses modified polypropylene material, which can effectively prevent cracking after a certain proportion. The installation of the upper and lower parts can be applied to the installation of various angles. The splash-proof interlayer at the bottom prevents the sample from splashing to a higher place, which will affect the data of the next experiment. The gas outlet interlayer is strictly used to control the amount of ammonia gas, so as n...
