Description

Thiocarbohydrazide produces agitating paddle

Technical field

The utility model relates to chemical production fields, and in particular to a kind of thiocarbohydrazide production agitating paddle.

Background technique

Thiocarbohydrazide, also known as sulfur carbazide, sulphur carbazide, equal diamino thiocarbamide, 1,3- diamino thiocarbamide, N, N- be bis-- (2,4- dimethylimino methyl) methylamine, is widely used in organic synthesis, is the important life of high-efficiency broad spectrum herbicide-metribuzin Produce raw material.The production process of thiocarbohydrazide is reacted in totally-enclosed enamel reaction still, and stirring is all stirred using frame at that time It mixes, finds that frame type stirring is uneven in practice, cause local reaction violent, the reaction of some positions does not reach terminal, The crystallization of kettle wall, influences product yield and yield, simultaneously because reaction is to carry out in hermetically sealed reaction kettle, therefore part raw material adds The short time the phenomenon that raw material accumulation can occur when entering into reaction kettle, reaction is caused acutely to influence product quality.

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of thiocarbohydrazide production agitating paddle, The uniform stirring that thiocarbohydrazide may be implemented prevents it from accumulating the problem for causing local reaction violent.

The purpose of this utility model is achieved through the following technical solutions:

A kind of thiocarbohydrazide production agitating paddle, which includes stirring rod, agitating paddle, discharging impeller, separator, institute Agitating paddle stationary distribution is stated in the middle and lower part of stirring rod for realizing material stirring, on the separator is fixed in agitating paddle Portion, the discharging impeller are close to separator upper surface, and discharging impeller, which is actively socketed on agitating paddle, to be rotated around it, the stirring First gear is fixed on bar, the first gear is located above discharging impeller, and the corresponding discharging impeller is configured with second Gear passes through identical two gear drives of specification, the number of teeth of the second gear between the second gear and first gear The revolving speed of discharging impeller is greater than the revolving speed of separator thus by separator when the number of teeth less than first gear rotates stirring rod On material scraper under fall into the stirring region where agitating paddle, several through-holes are provided on the agitating paddle.

The through-hole open up angle and bore is different.

Identical two gears of the specification include gear three and gear four, and the gear three is engaged with first gear, institute It states gear four to be engaged with second gear, be connected between the gear three and gear four by drive rod, the drive rod activity peace It can be freely rotated on bracket and on bracket, the bracket is fixed on agitator side wall.

The agitating paddle number is the six roots of sensation in two layers of distribution, and three every layer, three agitating paddles are in spiral shell centered on stirring rod Revolve shape distribution.

The discharging impeller blade number is three and is spirally distributed that the width of every discharging impeller is from inside to outside gradually Become smaller.

The separator and the agitator that uses of stirring are circle, and shape between the edge of separator and agitator inner wall At gap between 1-5 centimetres.

The beneficial effects of the utility model are: the production method of thiocarbohydrazide is to close hydrazine hydrate at low temperature with C2S At production intermediate product, heating reaction product, which is decomposed, generates target product, and it is fixed that wherein hydrazine hydrate, which is liquid C2S, therefore It is usually to fill hydrazine hydrate in advance in agitator and then C2S is added in whipping process, this programme is started by separator in stirring Middle hydrazine hydrate and C2S separation are avoided into stirring before and both do not start to occur as soon as that local reaction that reaction is formed is violent asks Topic, the C2S that stirring starts on separator is uniformly distributed in hydrazine hydrate since centrifugal force disperses around automatically, while discharging Whole C2S on separator can be scraped in hydrazine hydrate while can also be prevented from blocking by impeller, further, since being distributed on agitating paddle The through-hole for thering are several shape size opening directions to be all different, so that the liquid for flowing through through-hole forms sinuous flow, further such that stirring Mix more uniform, effective solution local reaction violent problem.
