Description

Technical Field

[0001] The invention relates to the technical field of membrane impurity separation machinery, in particular to a turbulent flow type post-crushed membrane impurity separation device. Background Art

[0002] The use of mulch covering technology in cotton planting can achieve the effects of heat preservation, moisture retention and increased production. However, after the cotton is harvested, the mulch film remains in the soil. As the content of mulch film in the soil increases, this reduces cotton production and causes environmental pollution. Therefore, residual film recovery machinery has been developed. After the residual film is recovered, it needs to be crushed-separated-washed-dried-granulated to achieve resource utilization of the residual film. After mechanized recovery, the residual film has a high impurity content, mainly impurities such as cotton stalks, cotton boll shells and soil. At present, there are few equipment for residual film separation on the market and the separation effect is poor, which cannot better serve the subsequent resource utilization, and ultimately causes the waste of polyethylene residual film resources. As a key link in the resource utilization of residual film, the separation operation of film impurities is also a bottleneck link in the resource utilization of residual film. It is urgent to carry out relevant technical research and equipment development. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a turbulent flow-type post-membrane impurity separation device, which can effectively solve the problems of large amounts of impurities in mechanically harvested residual membranes, inability to meet subsequent residual membrane resource utilization, small numbers of residual membrane separation devices and poor separation effects.

[0006] Furthermore, the membrane impurity feeding device includes a feeding fan, a suction pipe and a conveying pipe. One end of the suction pipe is provided with a suction port, and the other end thereof is connected to the feeding fan. One end of the conveying pipe is connected to the feeding fan, and the other end thereof is connected to the membrane impurity separation device.

[0007] Furthermore, the membrane-impurity separation device comprises a diffusion chamber, a spoiler, an airflow trajectory turning plate and a height adjustment plate. The diffusion chamber is a rectangular box structure, and a front end side plate is provided with a feed port, which is connected to the membrane-impurity feeding device, and a spoiler is hinged at the feed port. The spoiler forms an angle with the front end side plate of the diffusion chamber, and the broken-up residual film is diffused into the entire diffusion chamber through the spoiler. At the same time, the movement direction of the residual film is controlled by adjusting the angle between the spoiler and the front end side plate to achieve the purpose of separation. The bottom of the diffusion chamber is open, and the membrane-impurity conveying device is arranged at the bottom opening. There are three airflow trajectory turning plates, namely a first airflow trajectory turning plate, a second airflow trajectory turning plate and a third Three airflow trajectory turning plates, the first airflow trajectory turning plate is arranged at the bottom of the diffusion chamber and is located at two-thirds of the top of the stalk conveying device, the second airflow trajectory turning plate is arranged at one-third of the top plate of the diffusion chamber, and the third airflow trajectory turning plate is arranged at the rear end of the top plate of the diffusion chamber. The three airflow trajectory turning plates are used to reduce the influence of eddy currents on the residual film, so that the residual film moves backward according to a predetermined motion trajectory. The rear end side plate of the diffusion chamber is provided with a discharge port, and the discharge port is connected to the wind-gravity separation device, and a height adjustment plate that can be adjusted up and down is provided at the discharge port.

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] like Figure 1 , Figure 2 As shown, this embodiment provides a turbulent flow-type post-crushing film impurity separation device, including a frame 1 and a film impurity feeding device 2, a film impurity separation device 3, a stalk impurity conveying device 4, a wind-weight separation device 5 and an impurity collecting box 6 arranged on the frame 1.

[0026] like Figure 3 As shown, the membrane impurity feeding device 2 includes a suction pipe 201, a feeding fan 202 and a conveying pipe 203. One end of the suction pipe 201 is provided with a suction port, and the other end thereof is connected to the feeding fan 202. One end of the conveying pipe 203 is connected to the feeding fan 202, and the other end thereof is connected to the membrane impurity separation device 3. The feeding fan 202 provides suction to suck the membrane impurity materials from the suction port, and the materials are broken up by the high-speed rotating blades 2021 inside the feeding fan 202 and blown out through the conveying pipe 203 and transported to the membrane impurity separation device 3.

[0027] like Figure 4 , Figure 5As shown, the membrane impurity separation device 3 includes a spoiler 301, a diffusion chamber 302, an air flow trajectory turning plate and a height adjustment plate 304. The diffusion chamber 302 is a rectangular box structure, and a front end side plate thereof is provided with a feed port 3021, and the feed port 3021 is connected to the membrane impurity feeding device 2, and a spoiler 301 is hinged at the feed port 3021. The spoiler 301 forms an angle with the front end side plate of the diffusion chamber 302, and the broken up residual film is diffused into the entire diffusion chamber 302 through the spoiler 301. At the same time, by adjusting the angle between the spoiler 301 and the front end side plate, that is, the spoiler angle, the movement direction of the residual film is controlled to achieve the purpose of separation. The spoiler angle ranges from 30 degrees to 90 degrees. The bottom of the diffusion chamber 302 is open, and the impurity conveying device 4 is arranged at its bottom opening. There are three air flow trajectory turning plates, namely a first air flow trajectory turning plate 3031, a second air flow trajectory turning plate 3032, and a second air flow trajectory turning plate 3033. The first air flow trajectory turning plate 3031 is arranged at the bottom of the diffusion chamber 302 and is located at two-thirds of the top of the stalk conveying device 4, the second air flow trajectory turning plate 3032 is arranged at one-third of the top plate of the diffusion chamber 302, and the third air flow trajectory turning plate 3033 is arranged at the rear end of the top plate of the diffusion chamber 302. The three air flow trajectory turning plates are used to reduce the influence of eddy currents on the residual film, so that the residual film moves backward according to a predetermined motion trajectory. The rear end side plate of the diffusion chamber 302 is provided with a discharge port 3022, the discharge port 3022 is connected to the wind-weight separation device 5, and a height adjustment plate 304 that can be adjusted up and down is provided at the discharge port 3022. The overlapping width between the height adjustment plate 304 and the wind-weight separation device 5 is adjusted to control the position of the residual film falling into the wind-weight separation device 5.

[0028] The left side plate or the right side plate of the diffusion chamber 302 is a movable cover 305, which is hinged to the top plate of the diffusion chamber 302 and is opened and closed by hinges and support rods, so as to facilitate the removal of some materials accumulated inside and adjust the angle of the spoiler.

[0029] like Figures 6 to 8As shown, the stalk conveying device 4 includes a conveyor belt 401, a gathering baffle 402, an auxiliary blanking plate 403, a chain transmission device 404 and a power source 405. The conveyor belt 401 is arranged at the bottom of the membrane impurity separation device 3, and a chain transmission device 404 and a power source 405 for driving the conveyor belt to rotate are arranged at the rear end thereof. The gathering baffle 402 is arranged on the conveyor belt 401, and the gathering baffle is inclined at a certain angle to the conveyor belt 401. The square plate 4021 at the rear end thereof is connected to the wind-weight separation device 5. The cotton stalks and impurities that fall due to gravity are transported backwards by the conveyor belt 401, and the cotton stalks and impurities on the conveyor belt 401 are gathered to the middle of the conveyor belt 401 by the gathering baffle 402. The auxiliary blanking plate 403 is obliquely arranged inside the wind-gravity separation device 5 and is located obliquely below the rear end of the conveyor belt 401. The cotton stalks and impurities are thrown to the auxiliary blanking plate 403 through the conveyor belt 401, and then slide through the auxiliary blanking plate 403 to the impurity collection box 6 below.

[0030] like Fig. 9 As shown, the auxiliary blanking plate 403 is tilted inside the wind-gravity separation component and is located in front of the film outlet 501, with an inclination angle of 150 degrees. The cotton stalks and impurities thrown by the conveyor belt 401 slide into the impurity collecting box 6 through the auxiliary blanking plate 403, and can block the stalks and impurities thrown by the conveyor belt 401 to prevent them from being discharged from the film outlet 501.

[0031] The wind-gravity separation device 5 as a whole is a conical structure with a large front end and a small rear end. The front end is installed at the discharge port 3022 of the membrane-impurity separation device 3, and the rear end is the film discharge port 501. The wind-gravity separation device 5 shrinks and converges the airflow, thereby effectively reducing the impact of pressure and facilitating the movement of light-weight residual film along the upper inner half of the wind-gravity separation device 5 to the film discharge port 501.

[0032] The working principle of the present invention is as follows:

[0033] The film impurities are sucked in and broken up by the feeding fan from the suction port, and then blown into the film impurity separation device through the conveying pipe. Under the action of the spoiler of the membrane impurity separation device, the broken up residual film is diffused to the entire sealed diffusion chamber with the airflow. Impurities with larger specific gravity (such as cotton stalks, etc.) fall to the stalk impurity conveying device due to gravity, and are finally gathered by the gathering baffle and thrown to the auxiliary blanking plate, and then slide into the impurity collection box from the auxiliary blanking plate. The residual film with smaller specific gravity can be blown to the wind-weight separation device according to the predetermined route under the action of the airflow trajectory steering plate, so as to avoid the movement trajectory being affected by eddy currents. At the same time, since the wind-weight separation device adopts a conical structure with a large front end and a small rear end, it can shrink and gather the airflow, so that the residual film moves along the upper half of the wind-weight separation device and is finally discharged from the film outlet.

[0034] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and invention concept of the present invention within the scope disclosed by the present invention, which shall fall within the protection scope of the present invention.
