Liquid-adding mixing device for heptane preparation

Abstract

The invention provides a liquid-adding mixing device for heptane preparation. The device comprises a liquid-adding mechanism and a mixing mechanism, wherein the liquid-adding mechanism comprises raw material tanks, liquid-adding pipes and a liquid-adding pump; the raw material tanks are connected with the liquid-adding pump through the liquid-adding pipes; the cylinder number of the liquid-adding pump and the numbers of the liquid-adding pipes and the raw material tanks are same (at least two); the mixing mechanism comprises a mixing pipe, a mixing tank and a rotary mixing device, wherein the rotary mixing device comprises a rotary disc, a rotary motor, a mixing disc and a mixing motor; mixing grooves are uniformly formed in the upper part of the rotary disc; the rotary motor is connected to the bottom end of the rotary disc; the mixing disc is rotatably connected to the mixing grooves, and a mixing tank fixing groove is formed in the upper part of the mixing disc; the mixing tank is fixedly arranged in the mixing tank fixing groove; the mixing motor is fixedly arranged at the bottom of the rotary disc, and a rotary shaft of the mixing motor passes through the rotary disc and is connected with the mixing disc. The liquid-adding mixing device provided by the invention can be used for adding liquids of different raw materials at the same time, so that the liquid-adding time is shortened; the liquid-adding mixing device has the characteristics of being accurate to add liquid and efficient to mix.

Description

technical field [0001] The invention belongs to the field of mixing equipment, and in particular relates to a liquid-adding mixing device for heptane preparation. Background technique [0002] Heptane is a colorless and volatile liquid, which is often used as a standard and solvent for octane number determination, as well as for the preparation of organic synthesis and experimental reagents. Therefore, heptane exists in large quantities in laboratories and chemical companies. When preparing heptane or using heptane to prepare other reagents, more than one raw material needs to be mixed; the existing method is to take different amounts of raw materials according to the needs and then mix them. This method requires the operator to manually take the raw materials , so there must be a certain error in the amount of taking, and in order to make the error as small as possible, it must take too long to take the raw materials; at the same time, the subsequent mixing operation also h...

When preparing heptane or using heptane to prepare other reagents, more than one raw material needs to be mixed; the existing method is to take different amounts of raw materials according to the needs and then mix them. This method requires the operator to manually take the raw materials , so there must be a certain error in the amount of taking, and in order to make the error as small as possible, it must take too long to take the raw materials; at the same time, the subsequent mixing operation also has disadvantages such as long mixing time and poor effect
