Abstract

The utility model discloses a vacuum filter which comprises a casing (1), wherein a filter board (2) is transversely arranged in the casing (1), the inner part of the casing (1) is divided into a solid-liquid separating tank (3) and a filter liquid tank (4) from top to bottom by the filter board (2), and the filter liquid tank (4) is connected with a filter liquid outlet hole (5) and a vacuum tube (6) which is connected with a vacuum pump (7). The utility model utilizes a vacuum pumping and filtering principle to separate solid and liquid in solid-liquid mixture, has the advantages of simple structure and low cost, is suitable for small-separating quantity or intermittent separating process, avoids the problem of material wasting existing in the prior art, overcomes resource wasting phenomena and directly reduces the production cost of the vacuum filter.

Description

Vacuum filter

Technical field:

The utility model relates to a kind of filter plant that solidliquid mixture separates that is used for, especially a kind of simple in structure, cost is low, is applicable to the vacuum filter that less fractional dose or batch (-type) separate.

Background technology:

At present, being applied to the solidliquid mixture separation equipment in the industrial production, all is relatively to be suitable for the centrifugal separation technology of big fractional dose or continous way separation or to force extrusion technique, its complex structure, cost height basically.If this equipment is applied to less fractional dose or batch (-type) separation,, production cost of products is improved relatively with regard to existing the problem of equipment making and cost of use waste.

Summary of the invention:

The utility model is in order to solve existing in prior technology wasting of resources problem, provide a kind of simple in structure, cost is low, is applicable to the vacuum filter that less fractional dose or batch (-type) separate.

Technical solution of the present utility model is: a kind of vacuum filter, housing 1 is arranged, in housing 1, be horizontally arranged with filter 2, filter 2 will be separated into solid-liquid separation tank 3, filtrate receiver 4 up and down in the housing 1, be connected to filtrate with filtrate receiver 4 and portal 5 and vacuum tube 6, vacuum tube 6 joins with vavuum pump 7.

Described vavuum pump 7 is a water ring vacuum pump, and water ring vacuum pump places in the interlayer 8 below the filtrate receiver 4, is water ring vacuum pump below the interlayer 8 with tank 9, and non-return valve 10 is connected in vacuum tube 6 pipelines.

The utility model is to utilize the vacuum filtration principle that the solid in the solidliquid mixture is separated with liquid, simple in structure, cost is low, be applicable to less fractional dose or batch (-type) separating technology, avoid the existing in prior technology problem of " wasting one's talent on a petty job ", overcome wasting of resources phenomenon, directly reduce production cost of products, had high social and economic benefit.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment.

The specific embodiment:

Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: the housing 1 of making the end and upper shed with anti-corrosion materials such as PVC, geometries such as that housing 1 can be is square, circle, horizontally set one filter 2 in housing 1, filter 2 can be composited by poroid filter plate and industrial filter paper, and filter 2 will be separated into solid-liquid separation tank 3, filtrate receiver 4 up and down in the housing 1.Be connected to filtrate (liquid 5 and vacuum tube 6 with filtrate receiver 4, vacuum tube 6 joins with vavuum pump 7.Filtrate (liquid 5 is preferably disposed on the bottom of filtrate receiver 4, can with filtrate (liquid 5 valve 11 that joins, vacuum tube 6 is answered encapsulation process with housing 1 junction.Vavuum pump 7 can be the conventional vacuum pump, is placed on housing 1 side; Also can use water ring vacuum pump, can interlayer 8 be set below liquid bath 4, water ring vacuum pump is placed in it, be water ring vacuum pump below the interlayer 8 with tank 9, for preventing that the water in the water ring vacuum pump from driving in the wrong direction to filtrate receiver 4, is connected to non-return valve 10 in vacuum tube 6 pipelines.

The course of work:

Solidliquid mixture is put into separating tank 3 from the upper shed of housing 1, valve-off 11, start vavuum pump 7, filtrate receiver 4 is vacuumized, liquid in the separating tank 3 is under the effect of gravity and negative pressure, to enter in the filtrate receiver 4 by filter plate 2, solid is then stayed on the filter 2, reaches the purpose of Separation of Solid and Liquid.Open valve 11, filtrate is flowed out; Solid then can take out by the upper shed of housing 1.Can change the industrial filter paper on the poroid filter plate as required.

Claims

1. vacuum filter, housing (1) is arranged, it is characterized in that: in housing (1), be horizontally arranged with filter (2), filter (2) will be separated into solid-liquid separation tank (3), filtrate receiver (4) up and down in the housing (1), be connected to filtrate portalling (5) and vacuum tube (6) with filtrate receiver (4), vacuum tube (6) joins with vavuum pump (7).

2. vacuum filter according to claim 1, it is characterized in that: described vavuum pump (7) is a water ring vacuum pump, water ring vacuum pump places in the following interlayer (8) of filtrate receiver (4), be water ring vacuum pump tank (9) below the interlayer (8), non-return valve (10) is connected in vacuum tube (6) pipeline.
