Abstract

The utility model discloses a novel filter which comprises a filtering barrel and a main body seat. Filter elements are installed inside the filtering barrel, an upper cover is installed on the filtering barrel, the filter elements installed inside the filtering barrel are more than 20 in number, and the filter barrel and the main body seat are integrally formed by one shot. The novel filter can eliminate drawbacks existed in employment of threaded connection and welded mode, can improve production environment, and protects safety of operators. And the novel filter can increases filter area and filter capacity, and needs no central columns, thereby bringing more convenience for operations.

Description

A kind of novel filter

Technical field

The utility model relates to a kind of filter, particularly a kind of filter that is applied in the chemical industry.

Background technology

The filter that adopts in traditional chemical industry, the common maximum of its filtration yield can only reach 20 tons (can only adorn 18-19 in the filter vat at most and prop up filter core), and the assembling of lauter tub and base is normally adopted and is threaded and mode such as welding, the fixing of filter core all is to adopt spring of a filter core simultaneously, compress filter core by newel and nut again, to reach sealing effectiveness.Can bring following all disadvantage disappearances based on above technology: the restriction of lauter tub size can not be satisfied the demand of client to big traffic filtering fully, and it is higher relatively again that many filter costs are installed; Because filter medium is strong acid and strong base or the strong chemical liquid of corrosivity normally, and work characteristics with HTHP, therefore adopt aforesaid way to be threaded and to weld, long-term use may cause variety of problems such as leakage and cracking, and it is seriously unfavorable that production environment and operating personnel's safety is brought; Use newel and nut to compress filter core, operate loaded down with trivial details relatively, and can be because long-term the use cause newel fracture and screw to slide disadvantages such as tooth.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides the filter that a kind of filter capacity is big, security performance is good.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of novel filter comprises lauter tub and main body base, and filter core is installed in the lauter tub, and loam cake is installed on the lauter tub, it is characterized in that the described filter core that is installed in the lauter tub is more than 20, lauter tub and main body base one ejection formation.

As the utility model improvement of the technical scheme, in the described lauter tub pressing plate is installed, between pressing plate and the loam cake spring is installed, pressing plate at roof pressure under the effect of spring force on each filter core.

The filter core that the utility model adopts can reach 25.

The beneficial effects of the utility model are: the utility model is made of one piece by lauter tub and base, thereby can stop to adopt all disadvantage disappearances that exist when being threaded with welding manner, shape of product and weight are not limited, structural rigidity is sturdy and durable by force, there is not the doubt of stress pressure distortion yet, there is not manpower processing assembling may cause the problem of carelessness, be applicable to any harsh environment, thereby effectively solve original filter vat under the HTHP row culture and leakage or problems of crack in the working media of severe corrosive, thereby can improve production environment, protection operating personnel's safety; The lauter tub diameter that the utility model adopts can reach 500mm, and 25 of the 20 inch filter cores of can once packing in the bucket have improved filter area, the increase filtration yield greatly.Broken through the restriction that the 18-19 that in the past can only pack into props up filter core, made filtration yield bring up to 30 tons from 20 tons restriction.Can satisfy the demand of market, avoid causing the unnecessary wasting of resources because of flow uses many filters inadequately to big traffic filtering machine; The utility model need not newel, directly adopts loam cake to lock and compresses spring, makes pressing plate stressed average, and the filter core sealing effectiveness is better.Can avoid because of newel or sliding tooth of nut and newel breakage problem, it is also more convenient to operate, and only need open loam cake, just can take out filter core and clean, and has reduced before the time of unclamping the nut of newel.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that loam cake of the present utility model is in the cutaway view under the releasing orientation;

Fig. 2 is that loam cake of the present utility model is in the cutaway view under the locking releasing orientation;

Fig. 3 is the structural representation of lauter tub;

Fig. 4 is the vertical view of Fig. 3;

Fig. 5 is the structural representation of lauter tub and main body base.

The specific embodiment

With reference to figure; 3; Fig. 4; Fig. 5; a kind of novel filter; comprise lauter tub 1 and main body base 2; main body base is provided with filtrate import 7 and outlet 8; filter core 3 is installed in lauter tub 1; loam cake 4 is installed on the lauter tub 1; the filter core 3 that is installed in the lauter tub 1 is 25, and lauter tub 1 and main body base 2 one ejection formations, thereby can stop to adopt all disadvantage disappearances that exist when being threaded with welding manner; shape of product and weight are not limited; structural rigidity is sturdy and durable by force, does not also have the doubt of stress pressure distortion, does not have manpower processing assembling may cause the problem of carelessness; be applicable to any harsh environment; thereby effectively solve original filter vat under the HTHP row culture and leakage or problems of crack in the working media of severe corrosive, thereby can improve production environment, protection operating personnel's safety; improved simultaneously filter area greatly; increased filtration yield, broken through the restriction that the 18-19 that in the past can only pack into props up filter core, made filtration yield bring up to 30 tons from 20 tons restriction.Can satisfy the demand of market, avoid causing the unnecessary wasting of resources because of flow uses many filters inadequately to big traffic filtering machine.

With reference to Fig. 1, Fig. 2, pressing plate 5 is installed in the lauter tub 1, between pressing plate 5 and the loam cake 4 spring 6 is installed, make pressing plate 5 roof pressures on each filter core 3 by spring 6, therefore the utility model need not newel, directly adopt loam cake to lock and compress spring, make pressing plate stressed average, the filter core sealing effectiveness is better.Can avoid because of newel or sliding tooth of nut and newel breakage problem, it is also more convenient to operate, and only need open loam cake, just can take out filter core and clean, and has reduced before the time of unclamping the nut of newel.

Certainly, the filter core that the utility model adopts is not limited to 25, is satisfying under the big flow prerequisite, and increase or minimizing that filter core also can be suitable are not described further at this.

Claims
