Abstract
The utility model discloses a plate-and-frame filter press device for production of D-ethyl ester. The plate-and-frame filter press device comprises a plate-and-frame filter press; a material pressing pipe of the plate-and-frame filter press is connected with a booster pump through a pipeline; the booster pump is connected with a water tank and is provided with an outlet valve; a pipeline between the material pressing pipe and the booster pump is provided with a material pressing adjustment valve; and the material pressing pipe is provided with a pressure gage. By the plate-and-frame filter press device, a filter cake can be pressed to be dried completely, the amount of liquid in the filter cake can be reduced, water pressure is stable, the obtained filter cake is high in purity, the subsequent treatment can be facilitated, the quality of a product is improved, and production cost is reduced.
Description
Technical field
The utility model relates to D-ethyl ester production technical field, is specifically related to the plate compression device that a kind of D-of being used for ethyl ester is produced.
Background technology
D-ethyl ester, full name D-are the intermediates of Thiamphenicol to methylsulfonyl benzene serine ethyl ester, mainly are used for producing Thiamphenicol or Florfenicol and continuity product.
At present, in the production process of D-ethyl ester, a lot of operations need use the plate compression device, and the product that especially needs is under the situation of filter cake, and pressing dry of filter cake required than higher.And in traditional plate compression device, adopt gas as pressure medium, and this device has satisfied not the required requirement of D-process for producing ethyl far away, causes product quality to reduce, and simultaneously, repeatedly press filtration has also improved cost.
The utility model content
The utility model technical problem to be solved provides and is used for the plate compression device that the D-ethyl ester is produced, and it guarantees that the press filtration of sheet frame filter cake is complete, thereby eliminates defective in the above-mentioned background technology.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
Be used for the plate compression device that the D-ethyl ester is produced, comprise plate and frame filter press, it is characterized in that the binder pipe of said plate and frame filter press utilizes pipeline to be connected with booster pump, said booster pump connects tank, and said booster pump is provided with outlet valve.
As a kind of improvement, the pipeline between said binder pipe and the booster pump is provided with the binder control valve.
As a kind of improvement, said binder pipe is provided with Pressure gauge.
Through practice, find that hydraulic pressure effect when weather is relatively warmer is very good, but winter, because weather is colder, the water in the pipeline can freeze, and to very big of the damage of plate and frame filter press; Therefore winter, need in the tank to use salt solution, can effectively solve the colder problem of freezing easily of wintry weather.
Owing to adopted technique scheme, the beneficial effect of the utility model is:
The plate compression device that the utility model provides; Be particularly useful for pressing dry of filter cake in the production of D-ethyl ester; It utilizes booster pump that water is squeezed in the binder pipe of plate and frame filter press, can guarantee that water evenly distributes in the binder pipe, makes filter cake in plate and frame filter press, press dry better effects if.
The plate compression device that the utility model provides, the pipeline between binder pipe and the booster pump is provided with the binder control valve, simultaneously; The binder pipe is provided with Pressure gauge; In order to observe the hydraulic pressure in the control binder pipe, guaranteed the security of device, can guarantee that also hydraulic pressure is steady simultaneously.
In sum, it is more complete that the utility model press dry filter cake, reduces the amount of liquid in the filter cake, and hydraulic pressure is steady, and the filter cake purity that obtains is high, utilizes subsequent treatment, has improved the quality of product, has reduced production cost.
Description of drawings
Accompanying drawing is the utility model structural representation;
Among the figure: 1. plate and frame filter press, 2. binder pipe, 3. booster pump, 4. tank, 5. outlet valve, 6. binder control valve, 7. Pressure gauge.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in accompanying drawing, be used for the plate compression device that the D-ethyl ester is produced, comprise plate and frame filter press 1, the binder pipe 2 of said plate and frame filter press 1 utilizes pipeline to be connected with booster pump 3, and said booster pump 3 connects tank 4, and said booster pump 3 is provided with outlet valve 5.The utility model utilizes booster pump 3 that water is squeezed in the binder pipe 2 of plate and frame filter press 1, can guarantee that water evenly distributes in binder pipe 2, makes filter cake in plate and frame filter press 1, press dry better effects if.
In the present embodiment, the pipeline between said binder pipe 2 and the booster pump 3 is provided with binder control valve 6, and said binder pipe 6 is provided with Pressure gauge 7.Based on above structure, operating personnel can observe the hydraulic pressure in the control binder pipe 2, have guaranteed the security of device, can guarantee that also hydraulic pressure is steady simultaneously.
Present embodiment find that hydraulic pressure effect when weather is relatively warmer is very good, but winter, because weather is colder, the water in the pipeline can freeze in practical work process, and to very big of the damage of plate and frame filter press 1; Therefore winter, need in the tank to use salt solution, can effectively solve the colder problem of wintry weather.
The utility model is not limited to the above-mentioned specific embodiment, and all are based on the technical conceive of the utility model, and the structural improvement of having done all falls among the protection domain of the utility model.
