Abstract
Riboflavine sodium phosphate is after completing high vacuum dry closedown bipyramid vacuum pipe valve, and the vacuum in bipyramid higher than the vacuum in vacuum pipe, when opening atmospheric valve emptying tank body, can bring double-cone dryer into the impurity in air, polluted product material.The utility model provides a kind of high vacuum double-cone dryer for Riboflavine sodium phosphate drying, be made up of main frame, condenser, vacuum buffer tank, vacuum-pumping system, heating system and control system, it is characterized in that vacuum buffer tank has all independently been installed at the vacuum pipe place of each bipyramid at high vacuum double-cone dryer.By installing the improvement of vacuum buffer tank additional to high vacuum double-cone dryer, avoid because double-cone dryer causes material brought into contaminating impurity by air or cause material moisture content to uprise because damp atmosphere enters drying machine in antiaircraft air underfilling operation, decrease production rework rate; Its structure is simple, with low cost, improves the product percent of pass of Riboflavine sodium phosphate.
Description
Technical field:
The utility model relates to field of pharmaceutical equipment, specifically refers to a kind of high vacuum double-cone dryer for Riboflavine sodium phosphate drying.
Background technology:
Bicone revolution vacuum desiccator, because its internal structure is simple, easy cleaning, easy and simple to handle, the feature such as easy to maintenance, and higher dry materials speed and drying efficiency, evenly dry object can be reached, be thus widely used in the granulars of industry such as pharmacy, chemical industry, food or the drying of crystal material and mixing.
Carry out after Riboflavine sodium phosphate drying terminates at use bicone revolution vacuum desiccator, after closing bipyramid vacuum pipe valve, vacuum in bipyramid can higher than the vacuum in vacuum pipe, when opening atmospheric valve emptying tank body time (abbreviation emptying), once misoperation, not only can cause damage to the equipment of double conic rotary vacuum dryer, impurity in air may be brought into double-cone dryer in addition, thus polluted product material; And be introduced into damp atmosphere in drying machine material moisture content also can be caused to uprise.
Utility model content:
For solving the problem, the utility model discloses a kind of high vacuum double-cone dryer for Riboflavine sodium phosphate drying, be made up of main frame, condenser, vacuum buffer tank, vacuum-pumping system, heating system and control system, it is characterized in that vacuum buffer tank has all independently been installed at the vacuum pipe place of each bipyramid at high vacuum double-cone dryer; Described main frame forms primarily of rotating cylinder, vacuum suction pipeline, left and right gyroaxis, transmission device and frame; Described vacuum buffer tank is connected with the vacuum pipe of Vacuum Roots pump and two bipyramid inside respectively by pipeline; Described vacuum buffer tank is vertical, and exit is provided with filter.
The Main Function of vacuum buffer tank is buffer gas pressure; because the body bulk of surge tank is more much larger than the volume of pipeline; so during pressure instantaneous variation inside pipeline; pressure change inside jar is very little; so just than being easier to the pressure controlling surge tank outlet, steady pressure, reduce the impact impact of pulse; proterctive equipment, can effectively prevent suck-back phenomenon.
The beneficial effects of the utility model are:
1., by carrying out the technological improvement of dry high vacuum double-cone dryer to Riboflavine sodium phosphate, avoid and after closedown vacuum pipe valve, the foreign matter in pipeline or moisture content are introduced in material;
2. at the vacuum buffer tank arrangement that the vacuum pipe place of each bipyramid independently installs, reduce further Riboflavine sodium phosphate membrane filtration and moisture content disqualification rate in postorder production process, effectively reduce because membrane filtration and the defective product caused of material moisture content are done over again the waste of caused human and material resources;
3. the production equipment modified node method that does of the utility model is simple, with low cost, effectively improves operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model, wherein:
1. vacuum buffer tank, 2. filter, 3. atmospheric valve, 4. rotating cylinder
Detailed description of the invention
The utility model discloses a kind of high vacuum double-cone dryer for Riboflavine sodium phosphate drying, be made up of main frame, condenser, vacuum buffer tank, vacuum-pumping system, heating system and control system, it is characterized in that vacuum buffer tank 1 has all independently been installed at the vacuum pipe place of each bipyramid at high vacuum double-cone dryer; Described main frame forms primarily of rotating cylinder 4, vacuum suction pipeline, left and right gyroaxis, transmission device and frame; Described vacuum buffer tank 1 is connected with the vacuum pipe of Vacuum Roots pump and two bipyramid inside respectively by pipeline; Described vacuum buffer tank 1 is vertical, is provided with filter 2 in exit.
Before carrying out Riboflavine sodium phosphate drying operation, first condenser, vacuum buffer tank 1, vacuum-pumping system, heating system and control system are checked one by one, check that whether each device is normal; Then, Riboflavine sodium phosphate is added in container, after closing charging port lid and vacuum pipe valve, open Vacuum Roots pump, make in rotating cylinder 4 in 600 – 755mmHg negative pressure state; Then power turn-on switch, start drying machine motor, rotating cylinder 4 starts rotary work, then starts heater, carries out drying to Riboflavine sodium phosphate; After drying completes, first close heater, then in interlayer, inject cooling water, be cooled to after normal temperature until Riboflavine sodium phosphate, stopping vacuumizes, and closes bipyramid vacuum pipe valve respectively, opens atmospheric valve 3 and vacuum buffer tank 1, close drying machine motor, stop drying machine rotating, open port lid discharging.Independently vacuum buffer tank arrangement is installed by the vacuum pipe place at each bipyramid, reduce further Riboflavine sodium phosphate membrane filtration and moisture content disqualification rate in postorder production process, effective minimizing to be done over again the waste of caused human and material resources because of membrane filtration and the defective product caused of material moisture content, improves operating efficiency.
