Abstract
The utility model provides a bicone drying unit, wherein the quality of the dried finished product is stable and does not pollute environment, the operation is easy, and the cost is low. The drying unit comprises a constant temperature jacket, a cone and filter element, wherein the upper surface and the lower surface of the cone are respectively provided with a feeding hole and a discharging hole; sealing devices are arranged on the feeding hole and the discharging hole; the constant temperature jacket is arranged outside the cone; the constant temperature jacket is provided with a medium-in pipe and a medium-out pipe; a pollution discharge valve is arranged at the lower part of the constant temperature jacket; the filter element is arranged in the cone and is connected with a vacuum system by a vacuum pipe; and the medium-in pipe and the vacuum pipe are arranged on a straight line and are connected at the left and the right ends. The device changes the conventional filtration by a filter bag, thereby lowering the cost effectively, reducing environmental dust pollution to largest amount, lowering the labor intensity of workers, reducing the failure rate and the overhaul rate of equipment, and prolonging the service life of the equipment.
Description
Technical field
The utility model belongs to a kind of drying equipment, relates in particular to a kind of drying equipment that is used for 7-amino-cephalosporanic acid.
Background technology
The abbreviation of 7-amino-cephalosporanic acid is 7-ACA, and he is the important intermediate of present domestic production cephalosporin analog antibiotic.
At present domestic common employing chemical method is produced 7-ACA, because the 7-ACA of chemical method production is having crystallization under the condition of solvent, filtration, washing, therefore its crystal formation is thicker, and contain solvent, after having filtered, moisture is about 20%, and is dry easily, so adopt oven drying and boiled bed drying to come dry products more.
7-ACA with Production by Enzymes is in the aqueous phase crystallization, crystal formation is more tiny, specific area is big, so water content is big, and traditional bipyramid is all used filter bag, promptly wrap filter cloth with the metal tube of making eyelet, will be with traditional double-cone dryer drying, the end product quality instability causes dust pollution easily, complicated operation, cost is higher.
The utility model content
It is stable, free from environmental pollution that the purpose of this utility model provides the end product quality that a kind of drying goes out, operation easily, lower-cost bipyramid drying equipment.
In order to achieve the above object by the following technical solutions: comprise constant temperature jacket, cone, filter core, the cone upper and lower faces is respectively arranged with charging aperture and discharging opening, on charging aperture and the discharging opening sealing device is set, in the cone outer setting constant temperature jacket is arranged, constant temperature jacket is provided with into medium pipeline and goes out medium pipeline, be provided with sewage draining valve in the constant temperature jacket bottom, filter core is arranged on cone inside, and by vacuum pipe connection vacuum system, advance medium pipeline and vacuum pipe setting point-blank, be connected the left and right two ends of cone.
Filter core is connected to being threaded earlier on one 4 hole base, base and bipyramid be connected the connection of employing flange, be connected with the vacuum system of outside by vacuum pipe again.
The pore size filter of filter core is the 500-800 order.
Each double cone dryer uses four filter cores, four rectangular distributions of filter core.
Filter core is one-time formed integral filter filter core, and material can be one of papery, metal material, organic material.
Filter core is the one-time formed integral filter filter core that stainless steel is made.
Medium in the constant temperature jacket is a hot water.
The utility model adopts constant temperature jacket to help satisfying in the 7ACA dry run the demand of temperature, adopts filter core as the vacuum filtration cover first.Conventional vacuum filtration cover is to wrap filter cloth with the metal tube of making eyelet, and we are to use one-time formed integral filter filter core to be used as vacuum (-tight) housing and filter.It also is difficult for stopping up under the sticking situation of material, can keep the vacuum in the bipyramid preferably, and cracky does not run material.Even under the very thin situation of material particles, also can be blocked in bipyramid, and advanced less than in the vacuum system.This system filter bag of breaking the normal procedure filters, and can effectively reduce cost, and the minimizing environment dust pollution of maximum reduces working strength of workers, reduces breakdown rate and maintenance rate, prolongs the service life of equipment.
Description of drawings
Accompanying drawing is the structural representation of the utility model bipyramid drying equipment.
The specific embodiment
Embodiment
A kind of bipyramid drying equipment, comprise constant temperature jacket 1, cone 2, filter core 3, the cone upper and lower faces is respectively arranged with charging aperture 4 and discharging opening 5, on charging aperture and the discharging opening sealing device is set, in the cone outer setting constant temperature jacket is arranged, constant temperature jacket is provided with into medium pipeline 6 and goes out medium pipeline 7, be provided with sewage draining valve 8 in the constant temperature jacket bottom, filter core is arranged on cone inside, and by vacuum pipe 10 connection vacuum systems 9, advance medium pipeline and vacuum pipe setting point-blank, be connected the left and right two ends of cone.When dry, adding needs dry product, the sealing of charging and discharging mouth, and cone serves as the axle rotation to advance medium pipeline and vacuum pipe, opens vacuum system, feeds heat medium in constant temperature jacket, impurity is discharged by filter core and vacuum pipe.
Filter core is connected to being threaded earlier on one 4 hole base, base and bipyramid be connected the connection of employing flange, be connected with the vacuum system of outside by pipeline again; The pore size filter of filter core is the 500-800 order.
Each double cone dryer uses four filter cores, four rectangular distributions of filter core, and cross section is that four filter cores are located on four summits of rectangle respectively.Filter core is the one-time formed integral filter filter core that stainless steel is made.Medium in the constant temperature jacket is a hot water.
Filter core also can be papery, organic material and other metal materials.Such as copper, aluminium, polyethylene etc.
Medium in the constant temperature jacket also can be other fluid media (medium)s, such as machine oil, glycerine, atoleine etc.
