Abstract

The utility model relates to a molybdenum trioxide preparation system, comprising a configuration module, a reaction module, a low-temperature roasting module, a mother liquor recycling module, and an electric heating constant-temperature control module. The molybdenum trioxide preparation system is characterized in that the configuration module is connected with the reaction module; the reaction module is connected with the low-temperature roasting module; the low-temperature roasting module is connected with the mother liquor recycling module; and the electric heating constant-temperature control module is connected with the low-temperature roasting module. By adopting the electric heating constant-temperature control module, the molybdenum trioxide preparation system is more environment-friendly than a pushed-bat kiln of a gas, and high in thermal efficiency; an energy source is saved under the premise of ensuring the product quality; the resolution ratio of sodium molybdate solution is effectively improved by adopting a cycle decomposition mode; and the purity of the prepared molybdenum trioxide is greater than 99.5%.

Description

A kind of molybdic oxide preparation system

Technical field

The utility model relates to a kind of transmission mechanism, specifically relates to a kind of molybdic oxide preparation system.

Background technology

Common molybdic oxide preparation system is Powdered molybdic acid to be added in the rotary kiln calcine, this deficient mode exists drawback to have a lot, production time is long, production cost is high, thermo-efficiency is low, energy consumption is big, especially powder easily leaks, the shopwork environment is poor, influences the recovery of product, and other impurity can enter product simultaneously, influence quality product, the purity of product and granularity also are difficult to guarantee.

Summary of the invention

The utility model is at above problem, and a kind of environmental protection, low, the practical a kind of molybdic oxide preparation system of cost are provided.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of molybdic oxide preparation system, comprise configuration module, reaction module, low-temperature bake module, mother liquid recycling module, electrically heated thermostatic control module composition, it is characterized in that: configuration module ligation module, reaction module connects the low-temperature bake module, the low-temperature bake module connects the mother liquid recycling module, and electrically heated thermostatic control mould connects the low-temperature bake module.

The beneficial effects of the utility model are:

The utility model adopts electrically heated thermostatic control module, and than the pushed-bat kiln environmental protection more of combustion gas, the thermo-efficiency height is guaranteeing save energy under the product quality premise.And the mode that adopts circulation to decompose effectively improved the rate of decomposition of sodium molybdate solution, and the molybdic oxide purity of preparation is higher than 99.5%.

So the utility model compared with prior art has technical process weak point, mild condition, equipment is simple, energy consumption is low, pollute few characteristics.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a kind of structure iron of molybdic oxide preparation system.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing.

A kind of molybdic oxide preparation system, as shown in Figure 1, comprise configuration module, reaction module, low-temperature bake module, mother liquid recycling module, electrically heated thermostatic control module composition, it is characterized in that: configuration module ligation module, reaction module connects the low-temperature bake module, the low-temperature bake module connects the mother liquid recycling module, and electrically heated thermostatic control mould connects the low-temperature bake module.

When the utility model carries out work, the concentration that adds organics additive in the configuration module is the sodium molybdate aqueous solution of 15%-60%, then enter the operation of carrying out high pressure water thermal response, filtering separation, mother liquid evaporation crystal in the reaction module, the low-temperature bake module has adopted electrically heated thermostatic control technology, added electrically heated thermostatic control module, heat is imitated high, save energy, wherein, mother liquor decomposes by the circulation of mother liquid recycling module.

In sum, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
