According to the utility model, the problem that the storage temperature of initiators rises is effectively solved, the deterioration of initiators is prevented, the uniformity and stability of initiator feeding are improved, and the stationarity of the polymerization conversion ratio is significantly increased; and meanwhile, a phenomenon of flash polymerization caused by that the separated crystal is taken in a polymerizer in winter is avoided, thereby avoiding potential safety hazards.
Description
Technical field
The utility model relates to a kind of additive feeding device, relates in particular to a kind of paracril initiator inking device.
Background technology
Initiator is mainly used in generating in the paracril polyreaction initial active centre, trigger monomer and carries out polyreaction, and quality and flow when it adds paradigmatic system directly affect the activity of polyreaction, and then affect quality product.
First a certain amount of de-salted water is beaten to the initiator configured slot, pressed formula ratio and add specified amount initiator (Potassium Persulphate), stir stand-by after 4 hours.Before adding before the divinyl, in polymeric kettle only have liquid phase part because the divinyl of gas-liquid mixed not yet adds this moment, and polymeric kettle is vacuumized, and utilizes vacuum tightness that the power extraction initiator is provided, and metering is finished by scale tank.
The initiator feeding device comprises in the old production technique of my company: configured slot cell body, configured slot groove lid, configured slot outlet valve, scale tank, scale tank outlet valve, strainer, polymeric kettle feed valve, blow-down pipe, blow-off valve.At first open the configured slot outlet valve before the charging, the qualified initiator of configuration is put into the initiator scale tank, a certain amount of rear valve-off.During charging polymeric kettle is vacuumized, after vacuum tightness acquires a certain degree, open polymeric kettle feed valve, scale tank outlet valve, initiator can be drawn in the polymeric kettle, closes each valve of opening behind the quantitative initiator of suction, and charging is finished.
This kind technique is the use through 2 years in my company, finds to exist following problems:
1, summer temp is higher, when temperature is higher than 35 ℃, contacts with oxygen for a long time, and initiator not only can occur to decompose rotten, so that the amount of the initiator of actual participation reaction is lower than formula ratio, affects polymerization activity, has affected the steady rate of polymerisation conversion; Bring hidden danger also for simultaneously the safety in production of device.
2, the situation that solute is separated out can occur after the temperature variation in initiator in configured slot, has more crystal settling after for some time in configured slot, and during charging, the part crystal can be drawn in the polymeric kettle, affects polyreaction.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of paracril initiator inking device of safety and precise to be provided.
The utility model is achieved through the following technical solutions:
A kind of paracril initiator inking device, include configured slot, there is the groove lid configured slot top, groove covers and is provided with blow-down pipe, on the blow-down pipe with blow-off valve, the configured slot bottom also is provided with discharge nozzle, on the discharge nozzle with bleeder valve, described groove covers and is provided with the nitrogen inlet pipe, on the nitrogen inlet pipe with the nitrogen feed valve, configured slot is filled nitrogen, keep malleation, reduce oxygen to the impact of initiator, the outside of groove lid is provided with the U-shaped jacket pipe, what be connected with the U-shaped jacket pipe has water inlet pipe and a water outlet pipe, on the described water inlet pipe with the cooling water inlet valve and the hot water inlet valve that connect side by side, on the described water outlet pipe with the cooling water outlet valve and the hot water outlet valve that connect side by side, can pass into circulating water or hot water, the initiator storage-temp is controlled, also be provided with thermometer on the described configured slot, for the temperature of initiator is weighed.
Described a kind of paracril initiator inking device is characterized in that: also be provided with tensimeter on the described configured slot, show the configured slot internal pressure.
Principle of work of the present utility model is: when temperature is higher than 15 ℃ within thermometer shows the initiator configured slot; Slightly open a little blow-off valves, first a certain amount of de-salted water is beaten to the initiator configured slot, press formula ratio and add specified amount initiator (Potassium Persulphate), shut configured slot groove lid, stir open the nitrogen feed valve after 4 hours and pass into 0.1-0.2Mpa nitrogen after, close the nitrogen feed valve, keep malleation in the still, stand-by.When temperature is higher than 25 ℃ within thermometer shows the initiator configured slot, open 7 ℃ of cooling water inlet valves and cooling water outlet valve, pass into recirculated cooling water and lower the temperature, keeping the interior temperature of configured slot is the 20-30 degree.
When temperature is lower than 15 ℃ within thermometer shows the initiator configured slot, at first a certain amount of de-salted water is beaten to the initiator configured slot, open hot water inlet valve and hot water outlet valve, when passing into circulating hot water the de-salted water temperature being risen to 20-25 ℃, press formula ratio and add specified amount initiator (Potassium Persulphate), shut configured slot groove lid, stir after the nitrogen valve feed valve passes into 0.1-0.2Mpa nitrogen after 4 hours, close the nitrogen feed valve, keep malleation in the still, stand-by.
The utility model has the advantages that: the utility model efficiently solves the problem that the initiator storing temp raises, prevent the rotten of initiator, so that reinforced homogeneity, the stability of initiator is improved, the steady rate of polymerisation conversion also increases substantially, also avoid the winter crystal to separate out and be brought into polymeric kettle and cause cruelly poly-, solved potential safety hazard.
