实施例Example

下面结合附图对本实用新型的技术方案作进一步阐述。Below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.

如图1所示，一种用于流体系统管道中的过滤器，外部是外筒5，外筒5的进口端与出口端的尺寸可以相同或不相同，不相同时在进口端设置变径管4同短接管3相连接。外筒5通过进口法兰1和出口法兰8，使设备连接在管道和管道、管道和设备、设备和设备之间。进口法兰1和出口法兰8的规格尺寸可以相同也可以不同。滤网6采用单层或多层各种规格的丝网卷制而成，通过进口压紧件2和端部压紧件8压紧在支撑结构7上，其入口端固定在外筒5的内壁上，并形成密封，尾端连接排污管10。在外筒体5后端连接反冲水(气)进口接管11。As shown in Figure 1, a filter used in fluid system pipelines, the outside is an outer cylinder 5, the size of the inlet end and the outlet end of the outer cylinder 5 can be the same or different, and if they are different, a reducing tube is provided at the inlet end 4 is connected with the short connection pipe 3. The outer cylinder 5 passes through the inlet flange 1 and the outlet flange 8, so that the equipment is connected between pipelines, pipelines and equipment, equipment and equipment. The specifications and dimensions of the inlet flange 1 and the outlet flange 8 can be the same or different. The filter screen 6 is made of single-layer or multi-layer wire mesh of various specifications, and is pressed on the support structure 7 through the inlet pressing part 2 and the end pressing part 8, and its inlet end is fixed on the inner wall of the outer cylinder 5 and form a seal, and the tail end is connected to the sewage pipe 10. The recoil water (air) inlet connecting pipe 11 is connected at the rear end of the outer cylinder body 5 .

使用时，被过滤流体从进口流入过滤器，其中的杂质留在滤网6上，流体则穿过滤网从出口流出。对于较大的颗粒状杂质，在流体流动过程中，将被冲刷到过滤器滤网6的尾部，通过打开排污管10的阀门，可以直接在线排放，不影响整个流体系统的运行。当吸附的杂质较多，影响到流体流量时，过滤器的阻力就会增大，通过压力表的监测，可以判断过滤器是否堵塞。当过滤器阻力增大，流体通过率降低时，停闭主流系统，将过滤器两侧主流系统关闭，开启反冲水(气)进口接管11阀门和排污管10阀门，通过鼓入与主流体相同的介质或压缩空气等不影响流体介质的气体，反向冲刷滤网6，使吸附在滤网6上的杂质脱离，然后沿排污管10排放，实现顺利清洗和排污。During use, the filtered fluid flows into the filter from the inlet, and the impurities therein remain on the filter screen 6, and the fluid flows out from the outlet through the filter screen. Larger particulate impurities will be washed to the tail of the filter screen 6 during the fluid flow process, and can be directly discharged online by opening the valve of the sewage pipe 10 without affecting the operation of the entire fluid system. When the adsorbed impurities are more and affect the fluid flow, the resistance of the filter will increase. Through the monitoring of the pressure gauge, it can be judged whether the filter is blocked. When the resistance of the filter increases and the fluid passing rate decreases, shut down the main flow system, close the main flow systems on both sides of the filter, open the valve 11 of the backwash water (air) inlet connection pipe and the valve 10 of the sewage pipe, and pass through the main fluid The same medium or compressed air and other gases that do not affect the fluid medium reversely flush the filter screen 6 to remove the impurities adsorbed on the filter screen 6, and then discharge them along the sewage pipe 10 to achieve smooth cleaning and sewage discharge.

本结构还可以实现在滤网6损坏或不能完全冲洗干净的情况下，通过拆开进口法兰1和出口法兰8，松开进口压紧件2和端部压紧件8后，对滤网6进行更换，装入新滤网6。This structure can also realize that when the filter screen 6 is damaged or cannot be completely rinsed clean, by disassembling the inlet flange 1 and the outlet flange 8, loosening the inlet pressing piece 2 and the end pressing piece 8, the filter Net 6 is replaced, and new filter screen 6 is packed into.
