Description

Technical Field

[0001] This utility model relates to the field of molecular sieve processing, and in particular to a granulation device for molecular sieves. Background Technology

[0002] Molecular sieves are artificially synthesized hydrated aluminosilicates (zeolites) or natural zeolites that have the function of screening molecules. Structurally, they have many channels with uniform pore size and neatly arranged pores. Molecular sieves with different pore sizes separate molecules of different sizes and shapes. They have high adsorption capacity, strong selectivity, and high temperature resistance, and are widely used in organic chemical and petrochemical industries. They are also excellent adsorbents for coal gas dehydration. In addition, molecular sieves are increasingly valued for their application in waste gas purification. During the production process, molecular sieves need to be processed into granules using granulation equipment.

[0003] A search of Chinese Patent Publication No. CN221108129U reveals a granulation device for producing carbon molecular sieves. The device includes a base, a conveyor mounted on the top of the base via mounting columns, a mounting plate connected to the side wall of the conveyor, and a feed hopper mounted on the top of the conveyor. A pelletizing mechanism is provided on the mounting plate. A temporary holding plate is rotatably mounted on the side wall of the mounting plate away from the conveyor. A reciprocating lifting mechanism is provided between the temporary holding plate and the base. The temporary holding plate includes a heat-conducting plate, with a heat-conducting plate mounted on its top. A slot is formed in the top of the temporary holding plate, and a heater is installed within the slot. The heater contacts the bottom of the heat-conducting plate. The conveyor transports the material to the side wall of the mounting plate away from the conveyor. The pelletizing mechanism pelletizes the material at the discharge position on the mounting plate. The pelletized material falls onto the temporary holding plate, where the heater heats the heat-conducting plate, facilitating material drying and preventing material adhesion due to surface moisture during subsequent collection.

[0004] Although the aforementioned patent dries the material after pelleting, the molecular sieve that has just been cut is not yet fully shaped and may deform when shaken back and forth on the temporary plate, affecting the pelleting effect. Utility Model Content

A granulation cylinder 202 is fixedly connected to the support frames 201, and a feed funnel 203 is fixedly connected to the top of the granulation cylinder 202. A discharge mold 204 is fixedly connected to one side of the granulation cylinder 202. The discharge mold 204 has several through holes communicating with the inside of the granulation cylinder 202, so that the agglomerated raw material is squeezed out through the through holes.

[0027] The granulation cylinder 202 is equipped with an extrusion assembly, which includes an extrusion motor 301 bolted to the side of the granulation cylinder 202 away from the discharge mold 204. The output end of the extrusion motor 301 is connected to a rotating shaft 302 via a coupling. The rotating shaft 302 is rotatably connected between the inner walls of the granulation cylinder 202. A spiral blade 303 is fixedly connected to the rotating shaft 302.

[0028] A cutting assembly is provided at the discharge mold 204. The cutting assembly includes a mounting plate 401 fixedly connected to the top of the granulation cylinder 202. A rotary motor 402 is fixedly connected to one side of the mounting plate 401. Several circumferentially arranged cutters 403 are fixedly connected to the output shaft of the rotary motor 402. The cutters 403 abut against the discharge mold 204.

[0029] Below the cutting assembly is a collection assembly, which includes two vertical plates 501 fixedly connected to the top of the base 1. One end of the vertical plate 501 abuts against the support frame 201. An inclined guide plate 502 is fixedly connected between the two vertical plates 501. A vibration motor 503 is fixedly connected to the bottom of the guide plate 502. A collection box 504 is placed on the top of the base 1. The collection box 504 is located below the lower end of the guide plate 502.

[0030] An auxiliary mechanism is provided between the collecting component and the cutting component. The auxiliary mechanism includes an annular tube 601, which is fixedly connected to the top of the vertical plate 501. Several heating wires are fixedly connected between the inner walls of the annular tube 601, and several circumferentially arranged air nozzles 602 are fixedly connected between the inner walls of the annular tube 601. The annular tube 601 is inclined upwards, and there is an angle between the air nozzles 602 and the radial direction of the annular tube 601, so that the air blown out by the air nozzles 602 forms a vortex, which improves the full contact between the molecular sieve particles and the air, and improves the shaping effect.

[0032] Working principle: During use, the raw materials for producing molecular sieves are added to the granulation cylinder 202 through the feeding funnel 203. The extrusion motor 301 is started, which drives the rotating shaft 302 to rotate the spiral blades 303. While agglomerating and kneading the raw materials, the agglomerated raw materials are conveyed towards the discharge mold 204. Under the action of the discharge mold 204, the agglomerated raw materials are extruded into strips. The rotary motor 402 is started, which drives the cutter 403 to rotate, cutting the extruded molecular sieves into granules. Before the molecular sieve granules fall off... The blower 603 is started, and air is supplied to the annular pipe 601 through the air supply pipe 604. The air is blown out towards the molecular sieve particles through several air nozzles 602 to shape the molecular sieve particles. There is an angle between the air nozzles 602 and the radial direction of the annular pipe 601, and multiple sets of air nozzles 602 are arranged circumferentially, so that the blown air forms a vortex, which improves the full contact between the molecular sieve particles and the air and improves the shaping effect. Then the molecular sieve particles fall onto the guide plate 502 and slide down the guide plate 502 into the collection box 504 for collection under the action of the vibration motor 503.
