Abstract
The utility model discloses a press filter for preparing amantadine hydrochloride, which comprises a tank body and filters arranged in the tank body, wherein a liquid inlet is formed in the tank body; liquid outlets formed in the lower part of the tank body are communicated with outlets formed in the bottom of the filter through a horizontal pipeline. Through the utilization of the press filter for preparing amantadine hydrochloride, the liquid outlets are formed in the bottom of the tank body, and flush with the horizontal pipeline connected with the filter outlets, so that part of compressed air can be reduced by the pressure difference of the liquid in the press filter; the pressure in the tank is enabled to be kept to be 0.2 MPa, even smaller when the press filter is in operation; the production requirements can be satisfied; not only can the energy consumption be reduced, but also the dangerousness of the equipment operation can be lowered.
Description
Technical field
The utility model belongs to and prepares the amantadine hydrochloride technical field, relates in particular to a kind of pressure filter for the preparation of amantadine hydrochloride.
Background technology
Amantadine hydrochloride is a kind of three cyclic amine of symmetry, can suppress virus and penetrate host cell, and the shelling of impact virus, suppress its breeding, play treatment and preventing viral infection effect.
The refining link of amantadine hydrochloride, need to use filtering equipment.The production technology of its refining link is: water, hydrochloric acid, aminate are dropped in dissolving tank and react under the uniform temperature certain hour, react after complete material is imported in pressure filter and filters, filtered the laggard standing certain hour in standing tank that enters, then feed liquid is pressed into concentrated distillation still and carries out distillation and concentration, after material is atherosclerotic, the cooling crystallization, centrifugal rejection filter and with acetone washing then, the gained pure substance is amantadine hydrochloride.
As shown in Figure 1, in the time of in working order, it is even higher that the pressure in equipment need to reach 0.6Mpa to the filtering equipment that uses in prior art, consume more electric energy, and higher pressure increased the danger of equipment operating.
Summary of the invention
The purpose of this utility model is to provide a kind of pressure filter for the preparation of amantadine hydrochloride, has solved the above-mentioned problems in the prior art.
In order to realize the purpose of this utility model, the utility model provides a kind of pressure filter for the preparation of amantadine hydrochloride, comprise tank body and be located at the interior filter of tank body, described tank body is provided with inlet, and the liquid outlet of being located at described tank body lower part communicates by horizontal pipe with the outlet of the bottom of being located at described filter.
Wherein, described filter is one or more.
Wherein, described tank body is provided with the pressure gauge for pressure in the monitoring tank body.
Wherein, described liquid outlet is one or more.
The pressure filter for the preparation of amantadine hydrochloride that utilizes the utility model to provide, the position of liquid outlet is located at the bottom of tank body and with the horizontal pipe that is connected filter outlet, is flushed, in pressured like this filter, the pressure differential of liquid can be saved the Partial shrinkage air, thereby make pressure filter when work, it is even less that the interior pressure of tank remains on 0.2Mpa, just can meet the needs of production, namely save energy resource consumption, reduce again the danger of equipment operating.
Description of drawings
Fig. 1 is the structural representation of pressure filter in prior art.
Fig. 2 is structural representation of the present utility model.
In figure, 1 pressure gauge, 2 tank bodies, 3 liquid outlets, 4 pipelines, 5 filters, 8 inlets.
The specific embodiment
, in order to make the purpose of this utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be understood to specific embodiment described herein only in order to explain the utility model, be not limited to protection domain of the present utility model.
The utility model provides a kind of pressure filter for the preparation of amantadine hydrochloride, comprise tank body and be located at the interior filter of tank body, described tank body is provided with inlet, and the liquid outlet of being located at described tank body lower part communicates by horizontal pipe with the outlet of the bottom of being located at described filter.The pressure filter for the preparation of amantadine hydrochloride that utilizes the utility model to provide, the position of liquid outlet is located at the bottom of tank body and with the horizontal pipe that is connected filter outlet, is flushed, in pressured like this filter, the pressure differential of liquid can be saved the Partial shrinkage air, thereby make pressure filter when work, it is even less that the interior pressure of tank remains on 0.2Mpa, just can meet the needs of production, namely save energy resource consumption, reduce again the danger of equipment operating.
Filter is one or more.Filter can arrange a plurality of according to the actual requirements, effective a plurality of filter is set can promotes the efficiency of filter liquide.
Tank body is provided with the pressure gauge for pressure in the monitoring tank body.Pressure gauge is set for the pressure in the monitoring tank body on the tank body of pressure filter, prevents that pressure is excessive, tank body exists explosion dangerous, and too little pressure is filtered slowly, and operating efficiency is low.
Liquid outlet is one or more.Liquid outlet can arrange a plurality of equally, and when the pressure filter internal filter was more, liquid outlet may can not meet the timely discharge of liquid less; According to actual conditions, a plurality of liquid outlets can be set.
Pressure filter in work, first injects material to be filtered, and injecting compressed air in tank body, compression liquid wherein, by after filter,, through piping, are discharged from liquid outlet, and described pressure filter is typically provided with carbon outlet, for the material that will comprise carbon, discharges.
The above is only preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
