Technical Field

The invention discloses a netless residue spitting machine and a drip irrigation tape manufacturing machine, and belongs to the field of plastic recycling and regenerating devices.

Background

A water ring granulating and pelletizing system is a pelletizing facility with the highest pelletizing efficiency after plastic is extruded. The operation process is that the materials are firstly melted in an extruder, the melted materials are extruded from a die head of a water ring granulating device, and after a rotating blade of the water ring granulating device cuts a material strip into particles, the material strip is immediately taken away by cooling water and is sent to a water material conveying device along a spiral structure pipeline of the device, and then is sent to a dehydrator. After water material enters the lower part of the dehydrator, the granular material is lifted to the upper end of the dehydrator along the axial direction of the dehydrator during spin-drying dehydration, the granular material is sent to the evaporator along the tangential direction, water flow is spun and filtered in the dehydrator, flows into a circulating water tank at the lower opening of the dehydrator, is pumped into a water ring granulating device through a circulating water pump after being cooled, and is reused. After entering the evaporator, the pellets fly in the tangential direction of the inner wall circle. Since the pellets are still hot at this point, the moisture carried on the pellets surface evaporates simultaneously in the evaporator while they spiral down the inner wall of the evaporator to the bottom. The granular materials are conveyed to a vibrating screen from a discharge port of the evaporator, and after being screened by the vibrating screen, the granular materials with qualified appearance are conveyed to a hopper by a granular material lifting device for temporary storage and waiting for packaging.

In the actual production process, the material forms the molten state in the extruder, before the die head of cutting the grain device from the water ring extrudes, need pass through microporous filter screen in the melting intracavity of extruder, because the material is formed by retrieving plastics processing, consequently probably contain impurity in the material, when the material passes through microporous filter screen, impurity will be blocked by microporous filter screen and remain on microporous filter screen, can guarantee the purity and the quality of the granule of rebuilding like this on the one hand, on the other hand also can protect water ring and cut the die head and the rotary blade of grain device. When impurity accumulation on the microporous filter is more, can influence microporous filter's function, influence production, need regularly wash or change, traditional way is shut down, unpack the extruder apart, take out microporous filter screen, with microporous filter screen sanitization or the microporous filter screen of more renewal, then will extrude the unit dress, start production, because the extruder structure is complicated, it wastes time and energy to dismantle and install, the production efficiency of production line down time long also can be to the enterprise produces the influence simultaneously. Therefore, whether to provide a cleaning scheme for the microporous filter screen without disassembling the extruder and stopping the production line becomes a problem to be solved urgently by those skilled in the art.

Detailed Description

The present invention is not limited by the following examples, and specific embodiments may be determined according to the technical solutions and practical situations of the present invention.

Example (b): as shown in figure 1, a netless residue spitting machine and a drip irrigation zone manufacturing machine comprises a die head base 1, a die head cover 2, a die head 3, a microporous filter plate 4 and a scraper 5, wherein a mounting groove 6 with an opening facing to the left is arranged in the die head base 1, the die head 3 and the microporous filter plate 4 are sequentially arranged in the mounting groove 6 from right to left, the feeding end of the die head 3 faces to the left, the discharging end of the die head 3 faces to the right, a transmission shaft 7 is axially arranged on the die head base 1, the transmission shaft 7 penetrates through the die head 3 and the microporous filter plate 4, the scraper 5 is fixedly arranged on the transmission shaft 7 on the left side of the microporous filter plate 4, the right end surface of the scraper 5 is contacted with the microporous filter plate 4, the die head cover 2 is detachably connected on the left side of the die head base 1, a plurality of micro-filter holes 8 are axially arranged, the deslagging hole 9 is positioned at the left side of the microporous filter plate 4, the lower end of the die head base 1 is provided with a deslagging pipe 10 communicated with the deslagging hole 9, and the lower end of the deslagging pipe 10 is provided with a gate or an end cover 11. The invention cancels the microporous filter screen in the existing extruder and replaces the microporous filter plate 4 with a plurality of miniature filter holes 8 on the plate surface, the aperture of the miniature filter holes 8 on the microporous filter plate 4 is equivalent to that of the filter holes on the traditional microporous filter screen, and the filtering effect is the same; meanwhile, the scraper 5 is arranged on the left side of the micro filter plate, the scraper 5 is driven to rotate on the left end face of the micro filter plate 4 through the transmission shaft 7, impurities and residues on the micro filter plate 4 can be scraped off, the scraped impurities and residues enter the residue discharge pipe 10 through the residue discharge port, and the impurities and the residues can be discharged by regularly opening the end cover 11. after the technical scheme provided by the invention is adopted, the service life of the micro filter plate 4 is longer than that of the micro filter screen, the micro filter screen is prevented from being frequently replaced, meanwhile, when the micro filter plate 4 is cleaned, an extruder is not required to be opened, only the feeding is required to be stopped, the scraper 5 is driven to rotate through the driving shaft, the residues and the impurities on the micro filter plate 4 can be scraped, the residues and the impurities enter the residue discharge pipe 10 through the residue discharge port, the production line is not required to be stopped, the extruder is not required to, the labor intensity is reduced, and the production efficiency and the discharging quality are improved.

Further, the scraper 5 includes a pair of blades which are centrosymmetric with respect to the drive shaft 7. Like this, the wearing and tearing of every blade are less, and the atress is more even, and transmission shaft 7 moves more steadily, can increase of service life.

Further, the blade is arc-shaped. Therefore, the blade can better scrape the residues and impurities on the microporous filter plate 4, and when the blade scrapes the residues, the residues which are contacted instantly each time are less, which is beneficial to reducing the abrasion of the scraper 5.

Further, the left side of the die head cover body 2 is provided with a feeding hole, and the feeding hole is communicated with the inside of the mounting groove 6.
