An improved enzymatic reaction catalyst adding device

Abstract

The invention provides an improved enzymatic reaction catalyst adding device which is characterized by comprising an aggregate bin, a feed pipe, a vibrator and a material scattering hopper, wherein a feed inlet is formed at the bottom of the aggregate bin; the feed pipe is connected with the bottom of the aggregate bin and a catalyst falling channel is formed inside the feed pipe; the vibrator is in hard connection with the feed pipe and is internally provided with a vibrating ball chamber, the vibrating ball chamber is internally provided with a steel ball, a gas inlet pipe and a gas outlet pipe which are communicated with the vibrating ball chamber are formed, a water inlet pipe which is communicated with the gas outlet pipe is arranged, and an atomizing nozzle is formed at the outlet of the gas outlet pipe; the material scattering hopper is connected with the feed pipe, a screen is arranged at the bottom, and an opening is formed in the side wall of the screen in a manner of corresponding to the atomizing nozzle. The powdery catalyst is quickly and uniformly scattered to a detection face sequentially through the aggregate bin, the feed pipe and the material scattering hopper under the action of a vibrating force of the vibrator. According to a vibrating method of a special structure, the vibration frequency is high and the vibration force is large and controllable; water vapor sprayed out from the atomizing nozzle is used for humidifying the catalyst, so that the improved enzymatic reaction catalyst adding device is quite applicable to adding catalysts with requirements for certain humidity.

Description

technical field [0001] The invention relates to a feeding device, in particular to an improved adding device of an enzymatic reaction catalyst. Background technique [0002] Organophosphorus pesticides are widely used in agricultural production. They have high acute toxicity and cause great harm to the environment and human health. Recently, the problem of excessive organophosphorus pesticide residues has brought serious hidden dangers to the safety of fruits and vegetables. Controlling pesticides One of the most effective ways to detect residues is to strengthen the detection of pesticide residues. The most commonly used detection method is enzymatic detection. The detection principle is: the enzyme catalyst catalyzes the substrate to undergo a hydrolysis reaction, and the hydrolyzed product reacts with the chromogenic agent to produce a yellow substance, while the organophosphorus pesticide inhibits the activity of the enzyme catalyst, thereby affecting The amount of hydr...

Problems solved by technology

There are special requirements for the time and amount of enzyme catalyst added during the detection process. The titration method can be used for catalysts whose physical state is fluid, but this is not applicable to the addition of catalysts whose physical state is powder, especially for the requirements The addition of powdered catalyst with a certain humidity, the present invention is an improvement for this defect, and provides an auxiliary device for adding powdered catalyst with a certain humidity
