Beneficial Effects

[0009] 1. The guide pipe of the utility model is installed and fixed at the bottom of the filter body, and both ends of the filter body are connected to the pipe. The spring is sleeved on the guide pipe, and the guide pipe guides the spring to prevent the spring from bending when under pressure during petrochemical production filtration. The sliding plugging pipe is inserted into the filter body, and the spring uses the bottom of the filter body as a support to exert an upward elastic thrust on the sliding plugging pipe, so that the sliding plugging pipe has a tendency to slide upward. The positioning block is installed and fixed inside the filter body, and the positioning block limits the sliding of the sliding plugging pipe to prevent the sliding plugging pipe from continuously sliding upward during petrochemical production filtration. When the inner tube of the filter is taken out of the filter body, the sliding plugging pipe slides upward under the thrust of the spring until it fits with the positioning block. At this time, the sliding plugging pipe seals the side pipe of the filter to prevent the liquid in the pipeline from entering the filter body and leaking out of the filter body upward during petrochemical production filtration.

[0010] 2. The inner tube of the filter of the utility model is inserted into the filter body, and the inclined guide plate is an inclined structure, so that the liquid entering the filter body from the pipeline flows along the inclined direction of the inclined guide plate to the sedimentation groove, and then enters the water inlet from the sedimentation groove. The depth of the sedimentation groove is deep, so the liquid entering the water inlet is initially intercepted and precipitated in the sedimentation groove, so that the dirt is precipitated at the bottom of the sedimentation groove. The arc support bar is installed and fixed in the inner tube of the filter. The arc support bar is symmetrical up and down to position the outer frame of the filter screen, so that the outer frame of the filter screen is installed and fixed in the inner tube of the filter. The liquid entering the water inlet passes through the filter screen, and the filter screen is symmetrical to the liquid flowing through the filter screen. The liquid is filtered twice to make the liquid flowing out of the liquid outlet relatively clean. The circular cover plate is installed and fixed on the upper part of the filter body, and the strip limit plate is inserted into the limit slot. The strip limit plate is used to axially position the inner tube of the filter to ensure the direction of liquid entry and exit. In petrochemical production filtration, the inner tube of the filter is prevented from rotating in the filter body to cause liquid entry and exit dislocation. When the inner tube of the filter needs to be taken out to clean the filter screen, the bottom of the inner tube of the filter, to which the sliding plug is tightly attached, slides upward as the inner tube of the filter is taken out to seal the side pipe of the filter, so as to prevent leakage when the inner tube of the filter is disassembled and assembled in petrochemical production filtration.
