Loose joint type pipeline filter
Technical Field
The utility model relates to a pipeline filtering device, in particular to a loose joint type pipeline filter.
Background
The pipeline filter is a filtering device for removing solid impurities in the process of conveying liquid through a pipeline, when the liquid flows through the pipeline filter, the impurities in the liquid are blocked, and the impurities in the liquid can be prevented from entering the water control valve and other equipment, so that the normal work of the water control valve and other equipment is ensured. Periodic maintenance is required to remove impurities from the pipe filter. The prior basket filter is a relatively common pipeline filter, and the prior basket filter(Basket type filter)Mainly comprises a connecting pipe, a main pipe, a filter basket, a flange cover and a fastenerAfter liquid enters the filter basket through the main pipe, solid impurity particles are blocked in the filter basket, and clean fluid passes through the filter basket and is discharged from the filter outlet. The prior basket filter has the following technical defects: the parts are more, and the structure is more complicated, and the processing cost is higher.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of complex structure and high processing cost of the existing basket filter, the utility model provides the loose joint type pipeline filter, which combines a filter basket with a loose joint body, eliminates the parts such as a flange, a flange cover, a fastener and the like, has the characteristics of simple structure, convenient installation and disassembly and low processing cost, and simultaneously has the function of pipeline loose joint.
The technical scheme of the utility model is as follows: the loose joint type pipeline filter comprises a loose joint body and a filter basket, wherein the filter basket comprises a filter basket seat and a filter screen, the filter basket seat and the filter screen respectively extend into the loose joint body from two ends of the loose joint body and are inserted together, a gap is formed between the extending position of the filter basket seat and the filter screen and the inner wall of the loose joint body, and a water passing channel is arranged on the side wall of the filter basket seat.
The loose joint body is cylindrical, and the upper end and the lower end of the loose joint body are both provided with external thread joints.
The filtering basket is a multi-stage filtering basket.
The filter basket is two-stage filter basket, and wherein the filter screen comprises one-level filter screen and second grade filter screen, and the one-level filter screen is the coarse filter screen, and the second grade filter screen is fine filter screen.
The utility model has the following beneficial effects: by adopting the scheme, the filter basket is combined with the loose joint body, and parts such as flanges, flange covers, fasteners and the like are eliminated, so that the filter basket has the characteristics of simple structure, convenience in mounting and dismounting and low processing cost, and simultaneously has the function of loose joint of the pipeline.

Fig. 3 is a schematic structural view of another embodiment of the filter basket 2 of the present invention.
In the figure, 1-a loose joint body, 2-a filter basket, 21-a filter basket seat, 22-a filter screen, 221-a first-stage filter screen, 222-a second-stage filter screen, 3-a water channel and 4-an external thread joint.
Detailed Description
The utility model will be further described with reference to the accompanying drawings in which:
as shown in fig. 1 to 3, a loose joint type pipeline filter includes a loose joint body 1 and a filter basket 2, the filter basket 2 includes a filter basket seat 21 and a filter screen 22, the filter basket seat 21 and the filter screen 22 respectively extend into the loose joint body 1 from two ends of the loose joint body 1 and are inserted together, a gap is formed between the inserted portion of the filter basket seat 21 and the filter screen 22 and the inner wall of the loose joint body 1, and a water passage 3 is formed in the side wall of the filter basket seat 21. Due to the adoption of the technical scheme, when the filter basket is used, the loose joint body 1 is directly connected in a pipeline, the loose joint body 1 can be used as a loose joint, liquid enters from one end of the loose joint body 1 and flows out from the other end of the loose joint body 1 after passing through the filter basket 2, the purpose of filtering impurities in the liquid is achieved, the loose joint body 1 is detached during maintenance, the filter basket seat 21 and the filter screen 22 are taken out and then are cleaned, then the loose joint body 1 is installed in the pipeline, and the maintenance and the cleaning are convenient. The utility model combines the filter basket 2 with the loose joint body 1, eliminates the components such as a flange, a flange cover, a fastener and the like, has the characteristics of simple structure, convenient assembly and disassembly and low processing cost, and simultaneously has the function of pipeline loose joint.
The loose joint body 1 is cylindrical, and the upper end and the lower end of the loose joint body are both provided with external thread joints 4. Can be directly connected in a pipeline through the external thread joint 4 and is used as a loose joint.
The filter basket 2 is a multi-stage filter basket. During the design, according to the impurity content that operating mode liquid contains, adopt multi-stage filtration can effectively avoid straining basket 2 to block up.
The filter basket 2 is a two-stage filter basket, wherein the filter screen 22 is composed of a first-stage filter screen 221 and a second-stage filter screen 222, the first-stage filter screen 221 is a coarse filter screen, and the second-stage filter screen 222 is a fine filter screen. The embodiment is an optimal mode, and two-stage filtration is adopted, so that larger-particle impurities are blocked during one-stage filtration, and smaller-particle impurities are blocked during two-stage filtration.
The above-described embodiments are not intended to limit the present invention, and any product which is substantially the same as the spirit and substance of the present invention should be construed as being within the scope of the present invention.
