Abstract
The invention discloses a drying device used for DHPPA. The drying device comprises a two-cone rotation drying unit and a heat supply unit, wherein the two-cone rotation drying unit comprises a support, a motor and a rotation drying cabin provided with two cones, the two cones of the rotation drying cabin are coupled with the support, the rotation drying cabin is provided with a heat supply circulating pipeline, a feed port, a discharge port and a through hole, the heat supply circulating pipeline is positioned on the inner wall of the rotation drying cabin, the pipeline port of the heat supply circulating pipeline is arranged at one cone, the feed port and the discharge port are oppositely arranged in the rotation drying cabin, the heat supply unit is communicated with the pipeline port of the heat supply circulating pipeline, the through hole is connected with a vacuum pipeline, the vacuum pipeline extends into the rotation drying cabin along the through hole, and a cloth bag is arranged at the pipeline port. After the drying device disclosed by the invention is applied, since the two-cone rotation drying unit is adopted, oxidation of products by air is blocked, the loss of the products is reduced due to the sealed environment, the moisture content and the appearance color of the products are effectively controlled, the yield of the products is improved, the consumption is reduced, and the pollution to the atmosphere is reduced.
Description
Technical field
The present invention relates to a kind of drying unit, relate in particular to a kind of drying unit for DHPPA, mainly belong to the technical field of chemical industry equipment.
Background technology
R-(+)-2-(4-hydroxyphenoxy) propionic acid ([chemical name] DHPPA) is crystallization in water finally, common product quality requirement moisture must not be greater than 0.3%, so require product just can meet quality standard through the drying room drying.
Drying equipment of the prior art is the pellet type drying oven, although the product moisture of oven dry can reach requirement, the product loss is large, and the dehumidified blower fan of partial material blows in atmosphere, causes atmosphere pollution; Appearance color yellow (being that portioned product is rotten), the outward appearance of product is poor.
Summary of the invention
The object of the invention is to propose a kind of drying unit for DHPPA.
Purpose of the present invention, to be achieved by the following technical programs: for the drying unit of DHPPA, it is characterized in that: comprise bipyramid rotary drying unit and heating unit, described bipyramid rotary drying unit comprises support, motor and rotary drying cabin, the bipyramid in described rotary drying cabin is coupling in support, and the rotary drying cabin is provided with thermal cycling pipe, charging aperture, discharging opening and openings, described thermal cycling pipe is located at rotary drying cabin inwall and pipeline opening is connected with heating unit through one of bipyramid, described openings connects vacuum pipe and is communicated with rotary drying cabin inner chamber through another cone, and openings is provided with cloth bag, described charging aperture be installed in rotary drying cabin vertical both sides relative to discharging opening.
Further, described heating unit comprises boiler, temperature controller, magnetic valve, the jet chimney that is connected to boiler and temperature-sensing probe, described temperature controller control connection magnetic valve and temperature-sensing probe, the controlled magnetic valve that is connected in of described jet chimney, described boiler is provided with return duct and the efferent duct be connected with thermal cycling pipe, and described efferent duct is provided with heat-exchanger pump.
Apply drying unit of the present invention, adopt bipyramid rotary formula drying unit, from having blocked the oxidation of air to product, the environment of sealing has reduced the loss of product, the content of moisture and the appearance color of product have effectively been controlled, improve product yield, reduced consumption, reduced the pollution to atmosphere.
The accompanying drawing explanation
Fig. 1 is the structural representation of the present invention for the drying unit of DHPPA.
The specific embodiment
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present invention is described in further detail, so that technical solution of the present invention is easier to understand, grasp.
As shown in Figure 1, for the drying unit of DHPPA, it comprises bipyramid rotary drying unit and heating unit 7 especially, and described bipyramid rotary drying unit comprises support 1, motor 11 and rotary drying cabin 2.The closed container of these rotary drying cabin 2 both sides tool bipyramids.The bipyramid in this rotary drying cabin is coupling in support 1, and motor 11 is fixed on support 1 and drives rotary drying cabin 2 axial rotation.This rotary drying cabin 2 is provided with thermal cycling pipe 3, charging aperture 4, discharging opening 5 and openings 6, wherein thermal cycling pipe 3 is located at rotary drying cabin 2 inwalls and pipeline opening and is connected with heating unit 7 through one of bipyramid, described openings 6 connects vacuum pipe 8 and is communicated with rotary drying cabin 2 inner chambers through another cone, and openings is provided with cloth bag 9, can prevents and run the material phenomenon.This charging aperture 4 be installed in rotary drying cabin 2 vertical both sides relative to discharging opening 5.
In addition, heating unit 7 comprises boiler 71, temperature controller 72, magnetic valve 73, the jet chimney 74 that is connected to boiler 71 and temperature-sensing probe 75, temperature controller 72 control connection magnetic valves 73 and temperature-sensing probe 75, the controlled magnetic valve 73 that is connected in of jet chimney 74, boiler 71 is provided with return duct 711 and the efferent duct 712 be connected with thermal cycling pipe 3, and efferent duct 712 is provided with heat-exchanger pump 76.
During concrete enforcement, carry out charging from the charging aperture in rotary drying cabin, close the rotary drying Cang Dege road mouth of pipe after charging, keep the rotary drying cabin in vacuum state, starter motor, the rotary drying cabin is turned round, start heating unit by thermal cycling pipe to the heat supply of rotary drying cabin, after heat supply a period of time, in the rotary drying cabin, liquid gas can occur and separate, tail gas can import exhaust gas treating device by vacuum pipe, the liquid separated can sample and detect moisture by discharging opening, and rear discharging up to standard gets final product.This dry run is clean and sanitary, and the amount of labour is little, and product color white out, without running the material phenomenon, without air pollution.
By above-mentioned character express, can find out, beneficial effect of the present invention: apply drying unit of the present invention, adopt bipyramid rotary formula drying unit, thereby blocked the oxidation of air to product, product color is white, and the environment of sealing has reduced the loss of product, the content of moisture and the appearance color of product have effectively been controlled, improve product yield, reduced consumption, reduced the pollution to atmosphere.
In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the present invention's scope required for protection.
