Description

Waste vinyl dehydration device using centrifugal force with improved dewatering performance}

The present invention relates to a waste vinyl dewatering apparatus using centrifugal force with improved dehydration performance, and more specifically, waste using improved centrifugal dehydration performance to collect high-purity waste vinyl by removing moisture and foreign substances by centrifugal force of waste vinyl. It relates to a vinyl dewatering device.

Generally, vinyls are subdivided into bags, packaging films, and agricultural films. Packaging films are categorized into food, electrical products, pharmaceuticals, and other industrial films, and packaging films or films discharged from industries can be said to be less polluted and more highly recycled than agricultural ones.

In addition, various types of vinyl discharged from daily life or vinyl used for agriculture in rural areas are generally treated as landfill or burned after use.

However, it is known that when landfilling vinyl, it takes at least several decades to dissolve and absorb naturally.

In addition, even in the case of vinyl made of biodegradable plastics, it decomposes only after about 30 years after landfill, and has become a major cause of serious environmental pollution.

Moreover, when the waste vinyl is burned and treated, there is a feature that can be utilized in the industry by using a heat source generated when burning, but the harmful gas generated when burning the vinyl is a serious problem that seriously pollutes the atmosphere.

In order to prevent such environmental pollution and air pollution, governments and corporations have introduced and implemented various support systems to recycle waste vinyl, but in reality, various measures for recycling have not been proposed.

As a commonly known recycling method, a method of recycling waste vinyl as a raw material capable of recycling the waste vinyl through the order of washing, grinding, heating, and compression is proposed, but all devices for recycling conventional waste vinyl Their structure was complicated, and their productivity was low, so recycling was expensive, resulting in low economic efficiency.

This is a picture showing the device's support bracket.

1 to 7, the waste vinyl dewatering apparatus using centrifugal force with improved dehydration performance of the present invention is largely a support frame 100, a dehydrator body 200, a screen 300, a drum 400, It includes a support bracket 500.

The lower portion of the support frame 100 is fixed to the ground, and the upper portion of the support frame 100 is installed to be inclined at a predetermined angle relative to the ground.

When the support frame 100 is formed to be inclined at a predetermined angle, when the waste vinyl is dehydrated, the waste vinyl is scattered by centrifugal force due to the rotation of the drum 400 to be described below, and moisture and foreign substances attached to the waste vinyl are reduced. After being seated under the dehydrator body 200 by gravity in the photo dehydrator body 200, the waste vinyl is scattered again by centrifugal force by the rotation of the drum 400, thereby effectively removing moisture and foreign substances attached to the waste vinyl. can do.

That is, the length of time that the waste vinyl stays in the dewatering device is increased to remove moisture and foreign matter attached to the waste vinyl, which goes to the next process without removing foreign matter attached to the waste vinyl that has been buried for a long time. This is to prevent the problem that the waste vinyl cannot be recovered, and consequently, the residence time of the waste vinyl is increased to completely remove moisture and foreign substances attached to the waste vinyl, thereby recovering high purity waste vinyl.

The dehydrator body 200 is installed in an inclined shape at a predetermined angle on the support frame 100, and the dehydrator body 200 may be formed integrally, but the upper cover 210 and the lower cover 220 By being installed separately, it is easy to perform maintenance by separating the upper cover 210 and the lower cover 220 during maintenance of the dehydrator body 200.

At this time, the upper cover 210 may be manufactured in a semi-circular shape more curved toward the upper side, and the lower cover 220 is manufactured in a semi-circular shape until the scattered waste vinyl is scattered to the upper side and sinks to the lower side. The residence time is improved, and thus, the weight of a large amount of waste vinyl seated on the drum 400 can be dispersed, thereby preventing overload generated in the drum 400.

One side of the dehydrator main body 200 is provided with an inlet 240 through which waste vinyl with moisture and foreign matter is attached, and an outlet 250 for discharging waste vinyl from which dehydration and debris have been removed by a dehydrator, and the dehydrator main body (200) A plurality of drain holes 230 are formed on one side of the lower side to discharge moisture and foreign substances, and the tank for collecting moisture and foreign substances under the drain hole 230 or purification to purify the collected moisture and foreign substances The device can be installed separately.

The cross-section of the dehydrator main body 200 is formed in an elliptical shape, and the cross-section of the dehydrator main body 200 is formed in an elliptical shape, so that when dehydrated waste vinyl, the cross-section of the dehydrator main body 200 is more circular than the case where the cross-section is circular. The residence time until it sinks and sinks to the lower side is improved, and accordingly, the weight of a large amount of waste vinyl seated on the drum 400 can be dispersed, thereby preventing overload generated in the drum 400.

The screen 300 is provided in an oval shape on the inner circumferential surface of the dehydrator body 200, and the screen 300 may be integrally formed, but is divided into an upper screen 300-1 and a lower screen 300-2. By being provided, it is easy to maintain by separating the upper screen 300-1 and the lower screen 300-2 during maintenance of the screen 300.

A plurality of perforations are formed on the screen 300, and moisture and foreign matters are discharged to the outside through the perforations, and foreign matters attached to the waste vinyl can be removed through the perforations by friction.

In the oval screen 300, waste vinyl increases the residence time with the drum 400 to remove moisture and foreign matter attached to the waste vinyl. The foreign matter attached to the waste vinyl is not removed and then proceeds to the next process. This is to prevent the problem of not being able to recover high-purity waste vinyl, and consequently, by increasing the residence time of the waste vinyl, it is effective in recovering high-purity waste vinyl by completely removing moisture and foreign substances attached to the waste vinyl. will be.

The reason why the cross-section of the screen 300 is oval is that the waste vinyl is rotated with the drum 400 to contact with the “U” shaped round bar 310 of the lower screen 300-2 to remove moisture and foreign matter. The waste vinyl, which is lighter in weight, is scattered as it moves toward the upper screen (300-1) where the oval starts, and increases the residence time moving to the drum (400) after contact with the support bracket (500), thereby increasing the amount of water and moisture attached to the waste vinyl. This is to remove foreign substances.

As illustrated in FIG. 3, a plurality of “U” shaped round bars 310 are installed in the longitudinal direction on the lower inner circumferential surface of the screen 300, and the “U” shaped round bars 310 are in a diagonal direction (of the drum of waste vinyl. It is installed in the direction of movement according to the rotational direction), and when the waste vinyl is moved, the plurality of “U” shaped round bars 310 limit the gradual movement, thereby controlling the amount of waste vinyl and simultaneously removing moisture and foreign matter from the waste vinyl. It is possible to remove moisture and foreign substances from waste vinyl.

The drum 400 is provided inside the dehydrator main body 200 and is coupled to the motor 420 and the shaft 422, and can be directly coupled to the motor 420, and the drum 400 and the motor 420 are coupled. ) The drum 400 receives power from the motor 420 and rotates by a separate pulley 421 installed on one side.

2 or 4, a spiral screw 410 is formed in the longitudinal direction of the outer circumferential surface of the drum 400, and the screw 410 adjusts the angle based on the cross section of the drum 400. The angle of the screw 410 can be adjusted according to the amount, type, and moisture content of waste vinyl, and the angle of the screw 410 can be selectively adjusted from an angle between 30 and 90°.

In addition, the pitch (Pitch) of the screw 410 is at least 1/2 ~ 1/5, that is, it is preferably formed about 72 ~ 180 ° relative to the center of the drum 400 and is installed in a spiral, the screw ( When the pitch of 410) is 1/2 or less, the number of the screws 410 is small, so the number of times that the waste vinyl and foreign substances come into contact with the screws 410 is not many, so the load on the drum 400 is small. , There was a problem in that the removal efficiency of moisture and foreign substances contained in the waste vinyl was lowered because the number of times the waste vinyl and the foreign matter contacted the screw 410 was relatively small.

In addition, when the pitch (Pitch) of the screw 410 is 1/5 or more, the number of the screws 410 is high, so that the number of waste vinyl and foreign matters is in contact with the screw 410, and thereby the drum 400 There was a problem that an overload occurred, leading to damage to the drum 400 and the motor 420.

Therefore, the pitch of the screw 410 is preferably at least 1/2 to 1/5, that is, formed about every 72 to 180° based on the center of the drum 400, and the pitch of the screw 410 It turns out that (Pitch) can be changed by those skilled in the art.

In addition, as shown in FIG. 5, the drum 400 is formed by welding a screw 410 to a metal steel pipe, and a scraper 430 may be installed on one side of the screw 410.

The scraper 430 is in direct contact with the waste vinyl when the drum 400 is rotated. When the drum 400 is rotated, the scraper 430 hits the waste vinyl and foreign substances so that the waste vinyl and foreign substances are It is intended to compensate for the problem that the screw 410 or the drum 400 is worn due to abrasion caused by the blow and the entire screw 410 or the drum 400 needs to be replaced.

At this time, the scraper 430 is manufactured in a form that can be attached and detached and assembled by bolting or assembled by a separate detachable port, and the scraper 430 has a predetermined length ( It is made to protrude as much as L) to prevent wear of the screw 410 end.

In addition, when the scraper 430 is worn, it can be replaced immediately to prevent wear and damage of the screw 410, and an unworn scraper 430 is installed to attach to the waste vinyl by hitting waste vinyl and foreign materials at all times. It is possible to improve the removal efficiency of the moisture and foreign matter.

6 to 7, the support bracket 500 is in a diagonal direction (moving direction according to the rotational direction of the drum of waste vinyl) inside the upper screen 300-1 inside the upper cover 210 of the dehydrator body. A plurality is provided, but the waste vinyl that is introduced is scattered by the rotation of the drum 400 and the waste vinyl that is scattered toward the upper screen 300-1 is blown to one end surface of the support bracket 500, thereby causing moisture and foreign matter. By removing the, and then the process of contacting the drum 400 after the blown waste vinyl falls, it is possible to prevent the overload generated in the drum 400.

That is, when a large amount of waste vinyl containing moisture and foreign substances is brought into contact with one end surface of the scraper 430 and stays in the scraper 430, the drum 400 is overloaded and thus the drum 400 is damaged due to overload. This is to prevent it.

In addition, the width of the support bracket 500 is wider from one side to the other, so that the waste vinyl can be hit to fit the fluid flow due to the rotation of the drum 400.

In addition, the lower surface of the support bracket 500 may be formed in a straight or round shape. When formed in a straight shape, a load may be generated on one end surface of the supporting bracket 500 when stagnant waste vinyl is stagnant. When formed in a round shape, after the stagnant waste vinyl is stagnated, the movement flow of the waste vinyl to the round shape can be smoothly reduced, thereby reducing the load generated on one end surface of the support bracket 500.

The support bracket 500 may be able to adjust the direction from the outside depending on whether or not moisture is attached to the waste vinyl, and is installed in a diagonal direction on the inner circumferential surface of the screen 300 to be external at an angle of about 30-50° (θ). It can be moved through the operation in the embodiment of the support bracket 500 can be changed by those skilled in the art.

Accordingly, according to the waste vinyl dewatering apparatus using centrifugal force with improved dewatering performance according to the present invention, a scraper 430 that can be attached and detached is installed on one side of the screw 410 to continuously blow the scattered waste vinyl to waste vinyl. There is an effect of preventing the wear of the screw 410 and maximizing the recycling of waste vinyl by discharging the contained moisture and foreign matter, the "U" shaped round bar 310 and the support bracket 500 on the inner circumferential surface of the screen 300 It is effective to prevent overload generated in the drum 400 by dispersing a large amount of waste vinyl weight, each of which is installed.

The configurations shown in the embodiments and drawings described in this specification are only the most preferred embodiments of the present invention and do not represent all of the technical spirit of the present invention, and various equivalents that can replace them at the time of this application It should be understood that there may be and variations.
