Description
Technical field
The utility model relates to pharmaceutical chemistry technical field, refers more particularly to a kind of phenylethyl barbituric acid crude product centrifugal device.
Background technology
Phenylethyl barbituric acid, a kind of long-acting barbiturate, there is calmness, hypnosis, anticonvulsant action, and can anti-epileptic, epilepsy grand mal and limitation to be shown effect and epileptic state has good effect, can be used for calmness, hypnosis, anticonvulsion, anti-epileptic, preanesthetic medication, with antipyretic and analgesic fit applications, treat hyperbilirubinemia of newborn, and on clinical controlling good effect, enjoy attracting attention of Ge great drugmaker.
Disclosed phenylethyl barbituric acid bulk drug isolation technique adopts common link-suspended basket centrifuge at present, and can produce a large amount of inorganization tail gas in phenylethyl barbituric acid centrifugal process, main component is methyl alcohol, ethanol and hydrogen sulfide.Wherein, ethanol is inflammable, volatile, has pungency, and its steam and air can form explosive mixture, meets naked light, high heat energy and causes combustion explosion, with oxidising agent generation chemical reaction or cause burning; Methyl alcohol has severe toxicity, volatile; Hydrogenchloride has asphyxiant smell, has strong stimulation to the upper respiratory tract, and have corrosion to eye, skin, mucous membrane, proportion is greater than air, meets malaria and produce white mist, very easily water-soluble.These tail gas volatility above-mentioned are large, atmosphere pollution, and harm humans is healthy, there is occupational health potential safety hazard, meanwhile, need to administer by manpower, thus increase the consumption of manpower in phenylethyl barbituric acid centrifugal process.
Therefore, be badly in need of a kind of novel centrifugation, the consumption of manpower can be lowered, improve production capacity and guarantee that tail gas is collected absorption in a organized way and recycles.
Utility model content
The purpose of this utility model is to provide a kind of phenylethyl barbituric acid crude product centrifugal device, to avoid tail gas to leak, and then reduces environmental pollution, improves Working environment, guarantee the healthy and job safety of employee.
For achieving the above object, the utility model is by the following technical solutions:
A kind of phenylethyl barbituric acid crude product centrifugal device, comprise Full automatic closed whizzer, the opening for feed of Full automatic closed whizzer is connected for the preparation of the neutralization pot of phenylethyl barbituric acid bulk drug with one, discharge port is connected with a Receiving bin, liquid discharge outlet is connected with a wastewater disposal basin, gas discharge outlet is connected with the inlet mouth of a condenser, the liquid outlet of condenser is connected with a solvent catch tank, water-in is connected with chilled brine pipeline with water outlet, non-condensable gas outlet above solvent catch tank is connected with a device for absorbing tail gas, and solvent outlet and a solvent of below receive bucket and be connected.
According to the utility model, the water-in of described condenser and water outlet are respectively equipped with a water intaking valve and outlet valve, and the solvent outlet of solvent catch tank is provided with a solvent outlet valve, and the drain hole of neutralization pot is provided with a baiting valve.
Phenylethyl barbituric acid crude product centrifugal device of the present utility model, its beneficial effect is the consumption that can reduce manpower in existing phenylethyl barbituric acid centrifugal process, guarantee that the tail gas neutralizing pot discharge is collected and high efficiente callback in a organized way, avoid alcohol gas, methanol gas and hydrogen sulfide leakage, environmental pollution is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of phenylethyl barbituric acid crude product centrifugal device of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, phenylethyl barbituric acid crude product centrifugal device of the present utility model is described in further detail.
As shown in Figure 1, for a kind of phenylethyl barbituric acid crude product centrifugal device of the present utility model, comprise Full automatic closed whizzer 1, the opening for feed 11 of Full automatic closed whizzer 1 is connected for the preparation of the neutralization pot 2 of phenylethyl barbituric acid bulk drug with one, discharge port 12 is connected with a Receiving bin 3, liquid discharge outlet 13 is connected with a wastewater disposal basin 4, gas discharge outlet 14 is connected with the inlet mouth 51 of a condenser 5, the liquid outlet 52 of condenser 5 is connected with a solvent catch tank 6, water-in 53 is connected with chilled brine pipeline 7 with water outlet 54, non-condensable gas outlet 61 above solvent catch tank 6 is connected with a device for absorbing tail gas 8, the solvent outlet 62 of below receives bucket 9 with a solvent and is connected.
According to the utility model, the water-in 53 of described condenser 5 and water outlet 54 are respectively equipped with a water intaking valve 71 and outlet valve 72, and the solvent outlet 62 of solvent catch tank 6 is provided with a solvent outlet valve 63, and the drain hole 21 of neutralization pot 2 is provided with a baiting valve 22.
Phenylethyl barbituric acid crude product centrifugal device of the present utility model use procedure is as follows:
Open the water intaking valve 71 on chilled brine pipeline 7 and outlet valve 72, close solvent outlet valve 63, open the baiting valve 22 of neutralization pot 2, phenylethyl barbituric acid crude product is delivered to Full automatic closed whizzer 1 by action of gravity, phenylethyl barbituric acid, waste water is effectively separated with tail gas simultaneously, phenylethyl barbituric acid precipitates under the influence of centrifugal force, discharge from discharge port 12 and enter Receiving bin 3, waste water enters wastewater disposal basin 4 from liquid discharge outlet 13, tail gas enters condenser 5 from gas discharge outlet 14, be frozen after salt solution fully cools and be collected into solvent catch tank 6, noncondensable gas enters device for absorbing tail gas 8.
When the liquid level in solvent catch tank 6 arrives 2/3, open solvent outlet valve 63 and collect, can guarantee that the solvent that solvent receives in bucket 9 does not contain noncondensable gas.Centrifugal process of the present utility model does not interrupt, fully-closed, until tail gas is collected complete in a organized way.
In sum, phenylethyl barbituric acid crude product centrifugal device of the present utility model can be widely used in producing phenylethyl barbituric acid bulk drug, and compared with existing centrifugal device, manpower consumption is few, and reclaim fully, it is practical.
