Description

Liquid filter

The technical field is as follows:

the present invention relates to a filtration technique.

Background art:

the existing liquid filter for continuously filtering solid impurities in liquid generally comprises a cavity with an inlet and outlet interface and an access cover and a cylindrical filter arranged in the cavity, wherein during filtering, liquid enters the cavity from the inlet interface, flows out from the outlet interface after being filtered by the filter, and when the filter is blocked by the filtered solid impurities to influence the filtering efficiency, the access cover is opened to replace a new filter. Since the existing liquid filter is static filtration, the filter is quickly blocked by solid impurities, and therefore, the filter needs to be replaced or cleaned frequently, which not only causes high use cost (more obvious when the labor cost is higher and higher), but also causes the situation that the filter cannot be replaced frequently (such as liquid food raw material which is exposed to air as much as possible to avoid being polluted by bacteria in the air).

The invention content is as follows:

the object of the invention is to provide a liquid filter which does not require frequent replacement or cleaning of the filter while ensuring the filtration efficiency.

The invention is realized in such a way, and comprises a containing cavity with an inlet interface, an outlet interface and an access cover, and a cylindrical filter arranged in the containing cavity, and is characterized in that a vibrator is fixed on the containing cavity, a one-way driving structure is arranged between the containing cavity and the cylindrical filter, the one-way driving structure comprises a fluted disc and a positioning ring, the fluted disc is fully distributed with one-way teeth on the periphery, the fluted disc is fixedly connected with the end part of the cylindrical filter, the positioning ring is arranged on the containing cavity and vibrates along with the vibration of the containing cavity, and the fluted disc at the end part of the.

In the working process, liquid enters the containing cavity from the inlet interface, and flows out from the outlet interface after being filtered by the cylindrical filter, in the filtering process, the vibrator drives the containing cavity to vibrate, the containing cavity passes through the positioning ring, the fluted disc transmits the vibration to the cylindrical filter, thus, the vibration force can not lead the solid impurities in the liquid to be covered on the filtering hole of the cylindrical filter for a long time, thereby improving the filtering efficiency of the cylindrical filter, and simultaneously, the service life of the cylindrical filter is greatly prolonged, moreover, when the positioning ring transmits the vibration to the fluted disc, because the positioning ring is directly contacted with the unidirectional teeth of the fluted disc, the vibration force inevitably drives the fluted disc to rotate in the vibration force, because of the action of the unidirectional teeth, the unidirectional teeth can only be driven to rotate in one direction, thereby the vibration force drives the cylindrical filter to rotate in one direction through the unidirectional teeth, thereby effectively avoiding the solid impurities from being gathered at the same position of the cylindrical filter to lead the cylindrical The filtering capacity is lost, the effective service life of the cylindrical filter is further prolonged greatly, and the service life of the cylindrical filter is prolonged greatly, so that the aim of no need of frequent replacement or cleaning is fulfilled under the condition of ensuring the filtering efficiency.

The one-way teeth of the fluted disc at the end of the cylindrical filter close to the access cover are one-way teeth distributed along the periphery of the circular disc, the corresponding positioning rings are circular positioning rings and are fixed on the access cover, the one-way teeth on the circular disc are positioned on the inner side wall of the circular positioning rings, the one-way teeth of the fluted disc at the end of the cylindrical filter far away from the access cover are one-way teeth distributed along the inner wall of the hole of the circular disc, the corresponding positioning rings are inverted T-shaped positioning rings and are fixed on a pipe fixedly connected with the inlet interface, the transverse parts of the inverted T-shaped positioning rings are positioned in the hole of the circular disc, the vertical parts of the inverted T-shaped positioning rings lean against the outer side of the circular disc and cover the one-way teeth, and the one-way teeth on the inner wall. Therefore, the cylindrical filter is positioned between the access cover and the inverted T-shaped positioning ring, and driven by the unidirectional teeth under the action of the vibration force of the inverted T-shaped positioning ring and the annular positioning ring to rotate along a single direction, and meanwhile, liquid materials led in by the inlet joint are led into the cylindrical filter through the pipe, filtered by the cylindrical filter and led out from the outlet joint.

Compared with the prior art, the invention has the advantage that the filter does not need to be replaced or cleaned frequently under the condition of ensuring the filtering efficiency.
