Description

Crude product filtering and dissolving system

The technical field is as follows:

the utility model relates to a medicine production and chemical production technical field especially relate to a crude filters and dissolution system.

Background art:

and after the crude product is crystallized, carrying out vacuum filtration on the crystallized liquid by using a flat filter, shoveling out the crude product by using a stainless steel spoon after the vacuum filtration, and then filling the crude product into an aluminum tin. And adding drinking water into the crude product to stir and dissolve the crude product for subsequent operation.

At present, a laminated filter is adopted to replace a flat filter, the crystallization liquid is directly filtered by the laminated filter, and the crystallization liquid is dried by nitrogen after the filtration is finished. The crude product is retained on a laminated filter card, and then dissolved after drinking water is added to the laminated filter.

The current crude product filtration and dissolution process adopts vacuum filtration operation time for a long time, and complex operation, is difficult for large-scale production, and the vacuum filtration goes out the powder and opens the operation, is not conform to GMP requirement, and opens the menstruum and volatilizes, is unfavorable for staff healthy. After the suction filtration, the coarse powder needs to be shoveled out by a stainless steel spoon, so that the risk is very high, the product is easily polluted, the GMP requirement is not met, and the operation is complicated.

The utility model has the following contents:

in order to solve the problems, the utility model provides a crude product filtering and dissolving system, which comprises a cylinder, a slag storage frame, a screen plate, a reinforcing rod, a gland beam, a laminated filter, a feeding port pipe, an exhaust port, a discharging port pipe and a sampling valve;

the device comprises a barrel, a pressure gauge and a nitrogen gas drying port are respectively arranged on two sides of the upper end of the barrel, a cover lifting crane for conveniently taking the barrel is arranged in the middle of the upper end of the barrel, a slag storage frame is arranged at the lowest end in the barrel, a screen plate is arranged above the slag storage frame, each screen plate is arranged above the slag storage frame to form a combined filtering device, the combined filtering device is arranged on a reinforcing rod, a plurality of groups of combined filtering devices are arranged in the barrel from bottom to top, the slag storage frame is only arranged at the uppermost end of the barrel, the slag storage frame positioned at the uppermost end of the barrel is tightly pressed by a pressing cover cross beam and then is locked and fixed at a central pressing point, the barrel is tightly locked by bolts on the outer wall of the barrel, the barrel is fixedly arranged outside a laminated filter, a feeding port pipe is arranged at the left lower end of the laminated filter, an exhaust port is arranged at the right end of the feeding port pipe, and a discharge port pipe is connected at the middle end of the bottom of the laminated filter, and a sampling valve is arranged on the discharge port pipe.

Preferably, the slag storage frame and the screen plate are sequentially installed, and 16 slag storage frames and 15 screen plates are installed in total.

Preferably, the outer wall of the cylinder body is provided with a handrail.

The utility model discloses beneficial effect: the utility model discloses a crude product filters and dissolving system has combination filter equipment in range upon range of formula filter, and combination filter equipment contains the otter board and deposits the sediment frame and constitute, falls into crystal liquid and mother liquor liquid with the filter, and crystal liquid inlet port and filter device intercommunication, mother liquor discharge port and mother liquor liquid are straight-through. Because the filtering area of the mesh plate of the laminated filter is several times that of a flat filter, and in addition, the nitrogen pressure is used for replacing vacuum, the pressure is higher, and the filtering speed is higher. The filter is used for filtering the crude product, the working efficiency is greatly improved, the operation time is one fourth of the original operation time, and the filter is in accordance with large-scale production. Because the full-closed filtration is adopted, the contact of materials with the outside is less, the cross contamination is less, the risk is low, and the smell of the solvent is greatly reduced.

After the stacked filtration is finished, the crude product is retained in the filter residue storage frame, and the crude product is washed by drinking water to be directly dissolved, so that the operation is simple, and the working efficiency is improved. The laminated filter is fully sealed for filtering and dissolving, and has the advantages of large liquid filtering area, high speed, large flow, large particle storage capacity and high filtering precision.
