Raw material mixing machine for petroleum refining catalyst zeolite molecular sieve production

Abstract

The invention discloses a raw material mixing machine for petroleum refining catalyst zeolite molecular sieve production. The raw material mixing machine structurally comprises a mixing cylinder, a sealing cover, a feeding hole, a discharge hole, a discharge control valve, a servo motor, a reducer, an energy-saving mixing transmission device, a main mixer and an auxiliary mixer; the mixing cylinder is of a conical structure; the sealing cover is arranged on the mixing cylinder and is in sealing connection with the mixing cylinder through electric welding; the feeding hole is formed in the upper left side of the mixing cylinder and is in penetration connection with the sealing cover through electric welding; and the discharge hole is formed in the lower side of the mixing cylinder and is ofan integral forming structure with the mixing cylinder. For the raw material mixing machine provided by the invention, by arranging the energy-saving mixing transmission device, the mixing machine isautomatically started to work when a raw material is added; a working mode can be automatically selected according to the amount of the mixed raw material; when the amount of the raw material is less, the main mixer is started only, so that energy and electricity conservation are realized; and when the amount of the raw material is relatively large, the auxiliary mixer is started and perform fullmixing on the raw materials, so that the working efficiency is improved, and the mixing effect is ensured.

Description

technical field [0001] The invention relates to the field of zeolite molecular sieve production equipment and technology, more precisely, it relates to a raw material mixer for the production of petroleum refining catalyst zeolite molecular sieve. Background technique [0002] Zeolite molecular sieve is an inorganic crystal material, which is widely used in the fields of catalysis, adsorption and ion exchange because of its regular pore structure, strong acidity and high hydrothermal stability, and plays an irreplaceable role. People's research on the artificial synthesis of zeolite molecular sieves can be traced back to the 1940s. Barrer et al. realized the artificial synthesis of zeolite molecular sieves for the first time through the study of the phase transition of natural minerals in hot salt solution. The prelude to zeolite molecular sieves. . However, there are the following disadvantages in the raw material mixer for the production of the petroleum refining catalys...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a raw material mixer for the production of petroleum refining catalyst zeolite molecular sieve, so as to solve the problem that the raw material mixer for the production of petroleum refining catalyst zeolite molecular sieve in the prior art only has a single mixer, and the mixing effect It is poor, and cannot automatically control the working status of one or two mixers according to the amount of raw materials. Manual control is required. Often, when there are few raw materials, the two mixers are in the open state, wasting electric energy, or when there are many raw materials, they are still only turned on. A mixer with slower mixing speed and less effective flaws
