Abstract

The utility model relates to a self-cleaning filter. A filter device is arranged in a tank body. The filter device is an inverse tapering type filter net arranged in the tank body. A balancing weight is arranged on the filter net. A spring is arranged on the filter net through a spring clip slice. The balancing weight is arranged at the lower end of the spring. The structure is simple. Solid impurities on the filter net can be automatically cleaned.

Description

The self-cleaning type filter

Technical field

The utility model relates to the filter of using in a kind of liquid one solid separation system, particularly relates to a kind of filter of using in the system oil system that leaches.

Technical background

In leaching the oily process of system, often contain a large amount of solid impurities such as material embryo in the miscella, be easy on evaporimeter fouling and cause vapo(u)rization system heat waste and liquid flooding, having a strong impact on the quality and the postorder processing of evaporation, solvent recovery and the crude oil of miscella.Therefore the miscella cleaning equipment is the key equipment that leaches in the oily process of system.In order to reach the purpose that miscella purifies, engineers and technicians, device fabrication producer and manufacturer successively design and have tested the cleaning equipment of many types.A kind of is tent formula filter, and it utilizes the deadweight of miscella to make miscella drop on automatic fitration on the tent formula filter from the immersion oil lattice, filter screen easily stop up and efficient low, simultaneously be contained in the infuser not easy to clean because of tent formula filter; Another kind is rotary (Asta-3746 formula) separator, and miscella enters rotary (Asta-3746 formula) separator under the pressure of pump, produces centrifugal force and separates, and is difficult to reach separating effect; Also having a kind of is salt solution precipitate and separate device, utilize suction such as the solid impurity of expecting embryo proportion to increase and precipitate and separate, but sediment can't utilize too greatly because of water content, and the while has also increased production cost because of the use of salt.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, the self-cleaning type filter that can remove solid impurity on the screen pack automatically.

For achieving the above object, the utility model adopts following technical scheme: a kind of self-cleaning type filter, filter is housed in tank body, and described filter is the reverse conical screen pack that is contained in the tank body, and balancing weight is housed on the screen pack.

Be equiped with spring by spring clip on screen pack, balancing weight is contained in the spring lower end.

The utility model is owing to be equipped with the reverse conical screen pack in tank body, balancing weight is housed on the screen pack, the impurity that adheres on screen pack so more for a long time, screen pack carries out the moment recoil, and counter-rotating is fallen under the gravity effect, and filter screen produces vibration under the balancing weight effect, to reach the purpose of slag dumping and certainly clear filter screen, the solid impurities such as material embryo that stop up screen pack fall into infuser material lattice, thereby have avoided the waste of material.Load onto spring on the screen pack its vibrating effect is strengthened, thereby improve the effect of contaminant removal.Behind the contaminant removal, screen pack reverses again and rises to original position, carries out normal filtration work.Because the utility model screen pack cleaning is automatically, need not dismantle, thereby avoid the leakage of solvent, reduced unsafe factor.Miscella enters self-cleaning type filter of the present utility model under the pressure of pump, filter pressure is big, efficient is high.Simultaneously, change screen pack arbitrarily at the big I of impurity granularity, to reach the filtration requirement, easy to operate.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A place enlarged drawing of Fig. 1.

The specific embodiment

As shown in Figure 1, the filter tank body is made up of upper shell 7, lower house 9, is respectively equipped with adpting flange 13 and following adpting flange 14 on the last lower house, and 13,14 of flanges are equipped with gasket seal 8, connect fastening with bolt 15.Be respectively equipped with miscella import 10, miscella outlet 1 and slag-drip opening 11 on the tank body.Reverse conical screen pack 6 and screen pack skeleton 4 are housed in tank body, and the periphery of screen pack 6 is fixing with the silk pressing 12 that is contained in 13,14 of flanges.Screen pack 6 is provided with spring clip 2, and spring 3 is contained on the spring clip 2, and balancing weight 5 is contained in spring 3 lower ends.The size of self-cleaning type reverse conical filter is decided with production scale.

Claims

1, a kind of self-cleaning type filter is equipped with filter in tank body, it is characterized in that, described filter is the reverse conical screen pack that is contained in the tank body, and balancing weight is housed on the screen pack.

2, self-cleaning type filter as claimed in claim 1 is characterized in that, is equiped with spring by spring clip on screen pack, and balancing weight is contained in the spring lower end.
