Embodiment 1

[0036] In the first embodiment, the conversion assembly 20 includes an inverted U-shaped mounting bracket 28. The mounting bracket 28 is provided with a power device 29. The power device 29 is used to provide vertical feeding power, which can be a hydraulic rod or a guide rail screw slide table. ; A number of filter screen sealing blocks 25 are arranged in a vertical line and fixed with the execution part of the power unit 29. Once the filter screen 15 is used for about 6 hours, it will be blocked by the power unit 29. Replace it every 6 hours. , to meet the production needs of a single shift.

Embodiment 2

[0037] In the second embodiment, the conversion assembly 20 includes a power device 29 and a turret 30; the power device 29 can be a motor, and its motor shaft is matched with the center of the turret 30; The frame 30 is fixed, and in this embodiment, the number of filter screen sealing blocks 25 can be four, six or eight; after the primary filter screen 15 on a single filter screen sealing block 25 is blocked, the power unit 29 is rotated to a predetermined angle ; For example, if the number of filter screen sealing blocks 25 is four, the power unit 29 rotates 90 degrees at a time; if the number of filter screen sealing blocks 25 is six, the power unit 29 rotates 60 degrees at a single time; Replacement; change every 6 hours to meet the production needs of a single shift.

[0038] like Figure 12-13 As shown, the secondary filter assembly 2 of the present application is used to filter and block a small part of the small particle impurities existing in the raw material of the...

Abstract

The invention relates to the technical field of drip irrigation tape extrusion molding, in particular to an alternate drip irrigation tape extrusion filtering system. Comprising a replaceable primary filtering assembly for coarsely filtering molten drip irrigation tape raw materials, a secondary filtering assembly for finely filtering the molten drip irrigation tape raw materials, and a device for heating all parts in the system, the driving device is connected with the primary filtering assembly for driving extrusion; the filtering gap of the primary filtering assembly is larger than that of the secondary filtering assembly; a metering pump is arranged between the primary filtering assembly and the secondary filtering assembly; a first pressure sensor for detecting the pressure of the water-cooling extrusion head is arranged between the secondary filtering assembly and the water-cooling extrusion head; therefore, the service life of a single filter screen is prolonged, the service time of a single filter screen is prolonged, the screen replacement frequency of single team production is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of drip irrigation belt extrusion molding, in particular to a rotary drip irrigation belt extrusion filtration system. Background technique [0002] Drip irrigation tape is made of soft plastic processed into a thin tube, and infiltration holes are processed on the thin tube; A kind of hose belt made by winding, there is a drip hole at a certain distance, and the water in the thin tube is transported to the root of the crop through the infiltration hole for local irrigation. This process is uniform and slow, and it can achieve precise irrigation. . [0003] At present, the forming process of drip irrigation belt is that the material is first formed into a molten state in the melting furnace, and the molten material is extruded from the water-cooled extrusion head through the filter screen; because the material is made of recycled plastic, the material contains impurities. , When the material passes through...
