External jacket is used for material is heated or cools off, double-deck agitating device is " soil " font agitating device, and filtering surface is pressed close to by its lower floor, can the ZOSU and the cleaning solution of solid be mixed fully like this, discharging device is a cone-shaped device, is convenient to material and emits.By the combination of end socket, top agitating device, filter and discharging device, realized enclosed filtration, washing, drying integrated production, this equipment has the advantage that solvent loss is few, production process is safe and reliable, easy to operate.
Also be provided with thermometer on the described end socket.
Described screen pack is located at the top of porous plate.
Described discharging device side is provided with nitrogen inlet.
Described double-deck the stirring is located on the end socket by mechanical seal.
Described double-deck the stirring is the setting of " soil " font, and the filtering surface of filter is pressed close to by its lower floor.
Filter and washing operation in, filter is retained in device top with solid, the filtrate filter of then flowing through enters the bottom discharging device.In drying process, nitrogen is entered by bottom discharging device side import, and the solid that the porous supporting plate of process filter and screen pack stir top purges, and removes and desolvates, and reaches the purpose of solid drying.After drying was finished, nitrogen still was blown into the top agitating device from the bottom discharging device through filter, from the discharging opening of the side of top agitating device solid-state ZOSU was blown out as product and entered packaging bag.
Advantage of the present invention is N-(benzyloxycarbonyl group) succinimide by the totally-enclosed filtration of the present invention's formation, washing, drying integrated device of refining, the N-that obtains (benzyloxycarbonyl group) succinimide product quality reaches primes, the isopropanol solvent loss is reduced to 3-5% from the loss 20-22% of prior art, easy to operate, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1, be used for the device of refining succinimide, it comprises end socket 1, top agitating device 1-9, filter 2 and discharging device 3; End socket 1 covers top agitating device 1-9, filter 2 is located between top agitating device 1-9 and the discharging device 3, end socket 1 is provided with charging aperture 1-1, gas phase pipe 1-2, phegma pipe 1-3 and the double-deck 1-5 of stirring, the double-deck 1-5 that stirs stretches in the agitating device 1-9 of top, top agitating device 1-9 is provided with chuck 1-7 outward, and agitating device 1-9 side, top is provided with discharging opening 1-8; Filter 2 comprises screen pack 2-1 and porous plate 2-2; Discharging device 3 is located at the below of filter 2, and discharging device 3 comprises liquid outlet 3-1.
Wherein, also be provided with thermometer T on the end socket 1.
Wherein, screen pack 2-1 is located at the top of porous plate 2-2.
Wherein, discharging device 3 sides are provided with nitrogen inlet 3-2.
Wherein, the double-deck 1-5 that stirs is located on the end socket 1 by mechanical seal 1-4.
Wherein, also be provided with interface 1-6a and the interface 1-6b that is used for heating and cooling on the chuck 1-7.
Wherein, double-deck stirring 1-5 is the setting of " soil " font, and the filtering surface of filter is pressed close to by its lower floor.
During work, the iso-propanol/toluene solidliquid mixture that contains ZOSU crystalline solid is pressed into the agitating device 1-9 of top with nitrogen from charging aperture 1-1, and the screen pack 2-1 that solid is filtered in the device 2 is trapped among the agitating device 1-9 of top.Solvent isopropyl alcohol and toluene then flow into bottom discharging device 3 through filter screen 2-1 and porous supporting plate 2-2, are discharged by liquid outlet 3-1.Finish filter operation thus.
