Description

The dry sieve separating device of polyacrylamide gel particles

Technical field

The utility model relates to the macromolecule field of fine chemical, is specially a kind of separating device of the dry sieve for polyacrylamide gel particles.

Background technology

Polyacrylamide (PAM) is acrylamide (Acrylamide, AM) homopolymers or with other monomer copolymerizations the general designation of line polymer, comprise anionic (APAM), cationic (CPAM), the physical aspects such as liquid state, glue, powdery are arranged.Polyacrylamide is a kind of water-soluble polymer of line style, it is one of most widely used kind in water soluble polymer, have a wide range of applications in industries such as oil exploitation, water treatment, textile printing and dyeing, papermaking, ore dressing, coal washing, medicine, sugaring, cultivation, building materials, agriculturals, the title of " all trades auxiliary agent ", " omnipotent product " is arranged.Polyacrylamide belongs to fine chemical product, also belongs to the new material category.Wherein the extra high molecular weight polyacrylamide is one of eight large fine chemical products of first developing of country, is also one of former State Planning Commission new material hi-tech industrialization key project.Polyacrylamide mainly is used in the fields such as oil exploitation, water treatment, papermaking, in industries such as weaving, metallurgy, sugaring, medicine, also is widely used simultaneously.Aspect oil exploitation, be mainly to use high molecular anion type polycrylamide; On water treatment applications with cationic use amount maximum; Cationic in paper-making industry, anionic has application.The process route that PAM produces generally, from acrylonitrile (AN) is raw material, is produced the AM aqueous solution through the AM device, then after the AM polymerization, generates the PAM blob of viscose, then through operations such as granulation, drying, grinding, screening, packings, obtains product; At present the device of domestic supporting drying, screening is also immature, can not meet industrial serialization production, and the yield of product is low, and quality can not meet the needs of subsequent handling.

The utility model content

The purpose of this utility model just is to provide the dry sieve separating device of the polyacrylamide gel particles that a kind of screening simple in structure, reasonable in design, dry is effective, the serialization degree is high and equipment investment is few.

The concrete technical scheme of the utility model is: comprise fluid bed dryer with and the top cyclone separator group of installing, the hot-air pipeline that install bottom; The import of described fluid bed dryer connects the polyacrylamide gel particles feeding line, outlet connects vibratory sieve and the first cyclone separator successively, the top of the first cyclone separator by pipeline connect filter, bottom connects sifter by pipeline; Described sifter is provided with three outlets and connects respectively grinder, fine powder hopper and mixed-hopper group; The bottom of described grinder connects the first cyclone separator by pipeline; The bottom line of described mixed-hopper group also connects rear connection blender, overhead line and connects rear connection the second cyclone separator, the top of described the second cyclone separator by pipeline connect filter, bottom connects the first cyclone separator by pipeline; Described blender bottom connects packing machine.

Such scheme also comprises:

Connect successively heat exchanger and pressure fan on the hot-air pipeline, on described heat exchanger, connect steam pipe line.

Described fluid bed dryer is the attention of horizortal oscillaing fluided bed drying machine.

Described blender is double-cone mixer.

Described vibratory sieve is linear vibrating screen.

Described grinder is excellent hammer mill.

Described packing machine is totally enclosed Semi-automatic quantitative packing machine.

The utility model screening simple in structure, reasonable in design, dry is effective, the serialization degree is high, can improve yield and the quality of polyacrylamide, thereby improves the technical indicator of subsequent handling product, reduces production costs.

The specific embodiment

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

Referring to Fig. 1, a kind of separating device of the dry sieve for polyacrylamide gel particles, comprise fluid bed dryer 1 with and the top cyclone separator group 3 of installing, the hot-air pipeline 2 that install bottom; The overhead line of cyclone separator group 3 also connects rear connection vent line 15; Connect successively heat exchanger 18 and pressure fan 16 on hot-air pipeline 2, connect steam pipe line 17 on heat exchanger 18; The import of fluid bed dryer 1 connect top that polyacrylamide gel particles feeding line 19, outlet connect vibratory sieve 4 and the first cyclone separator 5, the first cyclone separators 5 successively by pipeline connect filter 6, bottom connects sifter 7 by pipeline; Sifter 7 is provided with three outlets and connects respectively grinder 9, fine powder hopper 8 and mixed-hopper group 10; The bottom of grinder 9 connects the first cyclone separator 5 by pipeline; The bottom line of mixed-hopper group 10 top that connects rear connection blender 11, overhead line and connect rear connection the second cyclone separator 13, the second cyclone separators 13 by pipeline connect filter 14, bottom connects the first cyclone separator 5 by pipeline; Blender 11 bottoms connect packing machine 12.Each device is preferably: fluid bed dryer 1 is the attention of horizortal oscillaing fluided bed drying machine; Blender 11 is double-cone mixer; Vibratory sieve 4 is linear vibrating screen; Grinder 9 is excellent hammer mill; Packing machine 12 is totally enclosed Semi-automatic quantitative packing machine.

The workflow of this device is: after polyacrylamide gel particles enters drier, its water content is down to 10% of solid shape PAM, the NH that dry run produces from 75% of colloid ₃, H ₂O vapour and air together enter high-altitude by vent line.Dry complete PAM particle enters vibratory sieve, and from vibratory sieve, product out is transported to cyclone separator through negative-pressure pneumatic, and the material of cyclone separator bottom advances sifter, through sifter, is divided into three parts, and fine powder advances the fine powder hopper and enters bag; Coarse granule advances grinder and again grinds, then delivers to cyclone separator; Satisfactory particle transport, to the mixed-hopper group, makes the Product mix of differential responses still obtain even product, then by packing machine, measures pack.

For those skilled in the art, under the prerequisite that does not break away from the utility model principle, likely to concrete size, or partial structurtes make some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
