Description

Technical Field

[0001] This utility model relates to the field of molecular sieve processing technology, and in particular to an anhydrous co-processing device. Background Technology

[0002] The anhydrous co-processing unit is a device specifically designed for molecular sieve processing, primarily used for the anhydrous preparation of organic solvents and the efficient regeneration of molecular sieves. Molecular sieves, as porous materials, are widely used in adsorption, separation, and catalysis, playing a crucial role, especially in solvent dehydration. Traditional molecular sieve processing methods often employ static adsorption or simple dynamic circulation, resulting in low adsorption efficiency, incomplete regeneration, and high energy consumption. The anhydrous co-processing unit integrates spiral feeding, dynamic dispersion, and multi-stage calcination technologies, achieving uniform heating and dehydration of molecular sieves in a continuous flow state, significantly improving processing efficiency and product regeneration quality. This unit is particularly suitable for the production of high-purity organic solvents, such as pharmaceutical intermediates and electronic chemicals, and has broad market prospects.

[0003] Current molecular sieve dehydration technology has some problems in practical applications:

[0004] Uneven dispersion and excessively fast feeding: Traditional devices rely on gravity feeding, which makes molecular sieves prone to accumulating into clumps, resulting in uneven heating. In some areas, moisture is not completely removed, leading to poor regeneration. Due to incomplete dehydration, residual moisture may cause side reactions between the molecular sieve and the solvent, reducing product purity. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a waterless co-processing device, which overcomes the shortcomings of the prior art and effectively solves the problems of uneven dispersion and excessively fast feeding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A waterless co-processing device includes a calcining furnace stainless steel tube. The top outer wall of the calcining furnace stainless steel tube is provided with a feeding hopper for guiding molecular sieve feeding. The interior of the calcining furnace stainless steel tube is respectively provided with a spiral feeding assembly and a molecular sieve dispersion assembly, with the spiral feeding assembly located above the molecular sieve dispersion assembly.

[0008] The spiral feeding assembly includes a vertical pipe installed inside the stainless steel tube of the baking section furnace, spiral auger blades welded to the outer wall of the vertical pipe, a baffle plate welded to the bottom outer wall of the spiral auger blades, a feed inlet opened at the bottom of the outer wall of the vertical pipe, and a discharge cylinder welded to the bottom outer wall of the vertical pipe. The feed inlet is located on one side of the baffle plate, and the discharge cylinder has a discharge port located directly above the molecular sieve dispersion assembly on the bottom outer wall.

[0009] Preferably, the molecular sieve dispersion assembly includes a conical dispersion disk welded to the inner wall of the stainless steel tube of the baking furnace, guide plates evenly distributed on the outer wall of the conical dispersion disk, and positioning holes opened on the outer wall of the conical dispersion disk.

[0010] Preferably, a fixing ring is welded to the top of the outer wall of the stainless steel tube of the baking section furnace, and a support rod is welded between the fixing ring and the feeding hopper.

[0011] Preferably, a flange is welded to the outer wall of the bottom of the stainless steel tube of the baking section furnace.

[0012] Preferably, support frames are welded to the outer walls of both ends of the vertical pipe, and the support frames are welded to the inner wall of the stainless steel pipe of the baking furnace.

[0013] Preferably, the conical dispersion disc includes a ramp and a central plate, wherein the guide plate is disposed on the outer wall of the ramp, and the central plate is located at the top center of the ramp.

[0014] Preferably, a vent pipe is welded to one side of the outer wall of the stainless steel tube of the baking section furnace, and the vent pipe is located at the top of one side of the conical dispersion plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The anhydrous co-processing device designed in this invention utilizes the synergistic effect of the screw feeder and the molecular sieve dispersion assembly. During the feeding process, the molecular sieve is conveyed layer by layer by the screw conveyor blades, extending the feeding time and allowing it to dry thoroughly. Afterward, the molecular sieve is evenly dispersed by the guide plate of the conical dispersion disc, preventing accumulation. The dispersed molecular sieve is fully exposed to the thermal environment of the stainless steel tubes in the baking furnace, achieving comprehensive and uniform heating, further improving dehydration efficiency.

[0017] 2. The waterless co-processing device in this design slows down the feeding speed of the molecular sieve by coordinating the baffle plate and the feed port, further extending its residence time in the stainless steel tube of the baking section furnace. Combined with the directional airflow control of the vent pipe, it improves the overall heat preservation performance and reduces energy consumption. Attached Figure Description
