Description

Waste agricultural film wind power separation device containing sundries

Technical Field

The utility model belongs to the field of recycling of agricultural waste agricultural films, and particularly relates to a waste agricultural film wind power separation device containing impurities.

Background

The agricultural film is one of important material data of agricultural production, the technical application of the agricultural film greatly promotes the improvement of agricultural yield and benefit, and also drives the change of agricultural production modes and the leap development of agricultural productivity, but with the continuous increase of the application amount and the service life of the agricultural film, the white pollution caused by a large amount of residual agricultural film also seriously influences the progress of agricultural production. For many years, people have tried to develop a processing device which can reduce white pollution and effectively separate membrane impurities to change the membrane impurities into valuables, but the effect is so little that the suspense is generated.

The agricultural film looks thin and thin, but has very great effects, not only can improve the ground temperature, preserve soil moisture, preserve soil and preserve fertilizer, but also has the functions of weeding, preventing diseases and insects, preventing drought and resisting waterlogging and the like, for the seedlings just coming out of the soil, the agricultural film has the effects of protecting roots and promoting growth and the like, most of users adopt agricultural film planting to improve the yield aiming at the factors limiting agricultural development such as low-temperature rain, drought and poor, short frost-free period and the like, although the agricultural film plays an important role in agricultural production, many users only see the benefits brought by the agricultural film, but ignore some hazards caused by residual film left at the field after the agricultural film is used.

Therefore, the recycling of the waste agricultural films becomes an important development situation, the agricultural films are required to be subjected to multi-step treatment before being reused, the rinsing is not negligible, the waste agricultural films can be rinsed cleanly, redundant dirt is removed, and the waste agricultural films are beneficial to the later treatment and utilization.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a waste agricultural film wind power separation device containing impurities, which is reasonable in structure, convenient to use, energy-saving and environment-friendly, can effectively separate the impurity-containing mulching film from the impurities such as straws, cotton bolls and flowers in a field, and meanwhile, can be used for carrying out centralized recovery on the agricultural film, effectively reducing white pollution and improving the working efficiency.

The purpose of the utility model is realized as follows: a wind power separator for the used agricultural film containing impurities is composed of a separating tank with a diameter reducing pipe at 90 deg. on its top, a sieving drum with through holes on its wall, a straight drum with a bottom opening, an air collecting chamber outside the sieving drum, an air exhausting pipe on its top, an agricultural film discharging outlet at its bottom opening, an annular air homogenizing pipe surrounding the tank, and a 90 deg. upward discharge outlet on the top wall of said air homogenizing pipe, the lower end of the separation tank body is provided with an inverted cone-shaped discharge hopper, and a discharge port positioned below the discharge hopper is internally provided with an air-lock valve driven by a motor.

The utility model is composed of a separation tank body, a reducing pipe, a screen cylinder, a straight cylinder, an observation and maintenance hole, a feeding pipe hole, a branch air pipe, an agricultural film discharge hole, a motor, an air lock, an air outlet and a centrifugal fan blast pipe. The feeding hole at the middle lower part of the separation tank body of the air-conveying separation device for the agricultural film containing impurities is a 90-degree bent pipe, so that the agricultural film containing impurities after being crushed can conveniently enter and then upwards spray; the lower air inlet holes are distributed on the outer periphery of the separation tank body, the outlet of each air inlet hole is connected with a 90-degree elbow for specifying the air outlet direction, the length of each air inlet hole extending in a straight line in the tank body has a specified limit value, and the wind energy of the air inlet holes supplies air to the air inlet holes by a centrifugal fan, so that the crushed agricultural film containing impurities moves upwards in a suspension state when entering the air inlet holes; the discharge hopper with the inverted conical bottom is used for transferring and collecting the separated impurities; an air-lock is arranged below the discharge hopper, a motor drives a rolling shaft, and a plastic blade is arranged on the rolling shaft and used for preventing the air quantity from leaking downwards and conveying the separated sundries; finally, the separated impurities enter the next link for treatment through an impurity discharge port; an elbow which is similar to a horn is arranged above the separation tank body and is called a reducing pipe for conveying the separated agricultural film and the air quantity moving upwards; the lower end of the reducing pipe is connected with a cylindrical screen drum for removing dust and discharging redundant wind energy; the outside of the screen drum is sealed with an air outlet for collecting dust entering the dust removal device and guiding the discharged air volume; the lower ends of the air outlet and the screen drum are connected with a straight drum for conveying the separated agricultural film to an agricultural film collecting machine; the middle lower part of the separation tank body is also provided with an observation and maintenance hole which can be used for observing the internal condition and overhauling equipment.

The working principle of the device is as follows: the agricultural film containing impurities is crushed and then is sent into the separation tank body through a feeding pipe hole, and the mulching film containing impurities is thrown to the high altitude under the action of positive pressure generated by a centrifugal fan through a positive pressure blast pipe; due to the height of the tank body, sundries heavier than the agricultural film are influenced by gradual rising and low wind speed and fall freely through the agricultural film discharge port and the air lock to the sundries discharge port; the agricultural film is lighter, blows through the reducing pipe along with positive pressure wind power for buffering, then enters the screen drum and falls down from the straight drum.

The utility model is convenient to use, energy-saving and environment-friendly; the method can effectively separate the miscellaneous mulching films from sundries such as straws, cotton bolls and flowers in the field, and simultaneously, the agricultural films are intensively recovered, the cleanliness of the recovered residual films reaches 99%, and the recovery rate reaches 99%. Effectively reduce white pollution, promote the development of green agriculture to obtain effectual processing, it is not only convenient but also labour saving and time saving, can also improve work efficiency.

The utility model has reasonable structure, convenient use, energy conservation and environmental protection, realizes the effective separation of the mulching film containing impurities from straw, cotton boll, flower and other impurities in the field, simultaneously carries out centralized recovery on the agricultural film, reduces white pollution and improves the working efficiency.
