Description

Cutting and blockage clearing water washing type residual membrane separation device

Technical Field

The invention belongs to the field of agricultural machinery, and particularly relates to a cutting, blockage-removing and water-washing type residual membrane separation device for separating and recovering residual membranes from a cut membrane rod mixture.

Background

In recent years, the rapid popularization of mulching films remarkably promotes the development of agriculture in China, and meanwhile, the residue problem of agricultural mulching films is becoming more serious due to the difficult degradation of the mulching films, the incomplete recovery mechanism and the like. In order to solve the problem of serious white pollution caused by the increase of the usage amount of the mulching film, more and more people begin to develop and research the machinery for recovering the residual mulching film, and the problem of disposing the recovered and crushed mulching film is rarely researched. Most of the recovered residual film mixture is directly burned, which causes great resource waste and serious secondary pollution. The residual film is not recycled as a renewable material, mainly because the residual film after mechanical recycling is seriously wound with impurities such as cotton seeds, cotton stalks and the like and is difficult to separate, and the residual film can be recycled only by separating the residual film from the impurities.

At present, the traditional manual screening and film washing modes are mostly adopted for recovering the residual films, the working strength is high, the efficiency is low, large-scale operation cannot be realized, and especially the method is not designed by a tie for mechanically collecting the residual film mixture. Therefore, in order to solve the problems that the machine-harvested residual membrane mixture is difficult to treat and the residual membrane resource is wasted, a device capable of efficiently separating the residual membrane is urgently needed to be developed.

Detailed Description

The present invention will now be described in detail with reference to the drawings, which are given by way of illustration and explanation only and should not be construed to limit the scope of the present invention in any way.

As shown in figures 1-3, the cutting and blockage-removing water washing type residual membrane separation device comprises a box body 1; 2, fixing a cutter; 3 a gap type inner cylinder can be assembled, 3-1 a film inlet and 3-2 a cutting edge; 4, a feeding hole; 5, a motor; 6, feeding a cutter head; 7, a film collecting box; 8, filtering the plate; 9, a lower supporting limiting device, 9-1 bolts, 9-2 bases, 9-3 springs, 9-4 steel balls and 9-5 lower cutterheads; 10 a frame; 11 pump.

The use process of the cutting and blockage removing water washing type residual membrane separation device comprises the following steps: injecting water into the device to enable the water level to be slightly higher than the position of the fixed knife 2, feeding the water from the feeding hole 4, driving the assembled slit type inner cylinder 3 to rotate by the motor 5, so that the water in the stirring box body is in a vortex shape, and the posture of the mixture of the membrane impurities in the water is changed under the stirring action of the assembled slit type inner cylinder 3 after the mixture of the residual membrane and the impurities is crushed and subjected to primary impurity removal treatment. The bottom of the box body 1 is connected with a water pump 11, water flow with negative pressure enables residual films to enter the inner barrel 3 with an assembled slit through a small hole channel 3-1 on the inner barrel 3 with an assembled slit, the residual films enter a film collecting box 7 through a bottom water outlet, and a filter plate 8 is arranged in the film collecting box 7 to collect, separate and clean the residual films; impurities such as cotton stalks and the like cannot enter the assembled slit type inner cylinder 3 due to buoyancy and shape and size of the impurities, and are pushed outwards and upwards through the centrifugal action and buoyancy of water flow to be separated, so that the impurities such as the cotton stalks and the like are concentrated to four corners of the box body 1 and finally collected uniformly; silt, gravel and the like can settle to the bottom of the box body 1, so that the membrane impurity separation effect is realized.

In the rotating process, impurities such as cotton stalks and the like are adsorbed on small holes 3-1 on the surface of the assembled gap type inner cylinder 3 due to the negative pressure of water, at the moment, the assembled gap type inner cylinder 3 is equivalent to 12 moving blades, and a plurality of groups of cutting blades are formed by the assembled gap type inner cylinder 3 and the fixed blades 2 fixed on the frame, so that the cotton stalks and residual membranes can be cut open, and the cotton stalks float upwards under the buoyancy of the water and are pushed to four corners by centrifugal force to be collected uniformly.

The water flow with the residual film is sent to the film collecting box 7 by the water pump 11, the residual film is collected by the filter plate 8 with the aperture ratio smaller than that of the film inlet 3-1, and the water flow returns to the box body 1 through the bottom of the film collecting box 7, so that the water is recycled.

The method has the advantages that the principle is simple, the residual membrane is cleaned while the residual membrane is separated, two purposes are achieved, the water is recycled, the problem of residual membrane recovery can be solved, and the method has high practicability.

Finally, it should be noted that: the above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any other various modifications and improvements can be made by anyone in the light of the present invention.
