Description

Technical Field

[0001] The invention relates to the technical field of waste recycling, and in particular to an environmentally friendly polyethylene waste wax recycling device. Background Art

[0002] Wax-impregnated boxes are usually used to transport various products that need to be waterproof and moisture-proof. The production process is usually to immerse ordinary corrugated boxes in molten wax liquid, so that the surface and interior of the corrugated box are filled with wax liquid, so that the box has the characteristics of strong waterproof and moisture-proof ability and good pressure resistance. Among them, polyethylene wax is used in the wax liquid. However, polyethylene wax is usually difficult to degrade in the natural environment. Therefore, during the recycling process of the wax-impregnated box, the wax liquid in the wax-impregnated box needs to be separated to realize the recycling of polyethylene wax. The existing recycling process of the wax-impregnated box usually uses a crushing mechanism to separate the wax-impregnated box. The box is broken into pieces, which are then transferred to a hot water pool through a conveyor belt for heating, so that the wax liquid in the wax immersion box is in a molten state, and the water and the wax liquid are separated by the difference in density between them, thereby realizing the recovery of the polyethylene wax. In this process, the broken wax in the wax immersion box fragments is easy to adhere to the conveyor belt, thereby reducing the amount of polyethylene recovered, and the wax immersion box fragments are easy to float on the surface of the hot water, and only a small part of the wax immersion box fragments is immersed in water, thereby reducing the melting rate of the wax in the wax immersion box, thereby reducing the collection efficiency of the polyethylene wax.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] Compared with conventional recycling methods, during the process of cutting the cardboard, a part of the cardboard is first immersed in water for heating, so that the cardboard can absorb hot water and avoid the cardboard floating on the water surface, thereby improving the heating efficiency of the cardboard and thus improving the collection efficiency of the polyethylene wax. At the same time, by immediately sending the cardboard into hot water for heating after breaking it, the process of conveying cardboard fragments by conveyor belt is reduced, thereby preventing the wax on the cardboard fragments from adhering to the conveyor belt, reducing the loss of polyethylene wax and increasing the recovery amount of polyethylene wax.

[0016] The cardboard pieces are clamped by the clamping pieces so that the cardboard pieces are perpendicular to the water surface. Compared with the cardboard pieces being parallel to the water surface, when the cardboard pieces sink downward, the contact area between the cardboard pieces and the wax liquid on the water surface is small, thereby reducing the wax liquid attached to the surface of the cardboard pieces, thereby improving the collection efficiency of the wax liquid.

[0017] The scraper continuously squeezes the paperboard, so that the wax liquid inside the paperboard is quickly discharged, improving the separation efficiency of the wax liquid and the paperboard, and the scraper scrapes the surface of the paperboard to scrape off the wax liquid remaining on the surface of the paperboard, improving the collection efficiency of the wax liquid;

[0018] When the paperboard is immersed in hot water, the through holes increase the contact area between the paperboard and the hot water, thereby increasing the melting speed of the wax inside the paperboard and facilitating the discharge of the wax liquid inside the paperboard through the through holes, thereby improving the separation efficiency of the polyethylene wax and the paperboard;

[0019] By making the surface of the cooling plate concave and convex, the speed of water flow and wax liquid flowing through the cooling plate is reduced, thereby extending the cooling time of the water flow and wax liquid, allowing the wax liquid to fully solidify. In addition, compared with a flat cooling plate, the contact area with the water flow and wax liquid is increased, further allowing the wax liquid to fully solidify, thereby improving the recovery efficiency of the polyethylene wax.

[0040] Usually the melting point of polyethylene wax is between 90℃ and 120℃. The following describes the process of recycling polyethylene wax in the wax dipping box:

[0041] First, hot water with a temperature higher than 90°C is transported to the water inlet 1001 through an external circulating water supply device, and the hot water flows into the melting chamber 1003 through the inclined surface 1005, so that the melting chamber 1003 is filled with hot water until the height of the hot water is higher than the highest point of the cooling plate 4. The hot water enters the recovery chamber 1004, flows along the cooling plate 4 to the water outlet 1002, and flows back to the external circulating water supply device through the water outlet 1002, so that the hot water in the melting chamber 1003 and the recovery chamber 1004 is in a state of continuous flow from front to back, and then the wax-impregnated box to be recycled is flattened by the carton flattening device, so that the wax-impregnated box becomes a flat cardboard 6, and the cardboard 6 is successively transferred to the front side of the first fixed roller 2 and the second fixed roller 3 by the conveyor belt. At this time, the cardboard 6 is in a downward tilted state, and the edge of the cardboard 6 is in contact with the connection between the first fixed roller 2 and the second fixed roller 3. Then, the motor 201 is controlled to start, and the gears between the motor 201 and the first fixed roller 2 and the second fixed roller 3 are meshed to transmit the first fixed roller 2 to the counterclockwise direction, thereby driving the four cutter rings 2001 to rotate counterclockwise, and at the same time, the second fixed roller 3 is rotated clockwise. The first fixed roller 2 and the second fixed roller 3 rotate in opposite directions, thereby driving the cardboard 6 to pass through the first fixed roller 2 and the second fixed roller 3 and be transmitted to the rear side. In this process, the cardboard 6 is cut by the counterclockwise rotation of the cutter ring 2001 to form a cutting seam. Since the cardboard 6 is in a downward tilted state, when the cardboard 6 is transmitted to the rear side, When the cardboard 6 is cut, the cut part is first immersed in the hot water of the melting chamber 1003, so that the wax in the cut part of the cardboard 6 is melted first, so that the cardboard 6 absorbs water and prevents the cardboard 6 from floating on the water surface. Then, as the cardboard 6 continues to be transmitted backward, until the cutting seam penetrates the cardboard 6, the cardboard 6 is cut into five small pieces of cardboard 6 by the cutting ring 2001, and the cardboard 6 is separated from the first fixed roller 2 and the second fixed roller 3. The cardboard 6 falls completely into the melting chamber 1003. Since the rear end of the cardboard 6 is first soaked in hot water, as the cardboard 6 continuously absorbs hot water, the cardboard 6 gradually sinks downward. At this time, the cardboard 6 is heated by the hot water in the melting chamber 1003, so that the polyethylene wax in the cardboard 6 is melted into a wax liquid state and separated from the cardboard 6. At the same time, due to the wax The density is less than that of water, therefore, the wax liquid separated from the cardboard 6 will float on the water surface, at the same time, the hot water in the melting chamber 1003 and the recovery chamber 1004 is in a state of continuous flow from front to back, thereby driving the wax liquid on the water surface to flow backward continuously, and then the impurities in the water flow and the wax liquid are intercepted by the filter 5 to ensure that there are no impurities in the water flow and the wax liquid flowing into the recovery chamber 1004, and then the wax liquid flows to the surface of the cooling plate 4 together with the water flow, and the cooling plate 4 is continuously cooled by the cooling device installed at the bottom of the cooling plate 4. It is explained here that the water flow flowing through the surface of the cooling plate 4 is in a relatively thin water curtain state, and the cooling plate 4 can fully cool the water flow and the wax liquid, thereby ensuring that the wax liquid solidifies when passing through the cooling plate 4, and the water continues to flow to the water outlet 1002,Then the separation of water and wax liquid is completed, and then the polyethylene wax solidified on the surface of the cooling plate 4 is manually shoveled out, so as to realize the recovery of the polyethylene wax in the wax immersion box. Compared with the conventional recovery method, in the process of cutting the cardboard 6, a part of the cardboard 6 is first immersed in water for heating, so that the cardboard 6 can absorb hot water and avoid the cardboard 6 floating on the water surface, thereby improving the heating efficiency of the cardboard 6 and thus improving the collection efficiency of the polyethylene wax. At the same time, by immediately sending the cardboard 6 into hot water for heating after breaking it, the process of conveying the cardboard 6 fragments by the conveyor belt is reduced, thereby avoiding the wax on the cardboard 6 fragments from adhering to the conveyor belt, reducing the loss of polyethylene wax and increasing the recovery of polyethylene wax.

[0042] As the cardboard 6 is continuously transferred to the melting chamber 1003, since the wax liquid is on the upper layer of the water surface, when the cardboard 6 transferred later completely falls into the melting chamber 1003, more wax liquid will be attached to the lower surface of the cardboard 6, so that the cardboard 6 will carry a part of the wax liquid downward while sinking downward. Therefore, when the cutter ring 2001 cuts the cardboard 6, the clamping plate 20301 on the fixed plate 203 is clamped on the cutting seam of the cardboard 6. As the cardboard 6 is continuously transferred backward, the cutting seam on the cardboard 6 is enlarged by the clamping plate 20301, so that the distance between two adjacent small pieces of cardboard 6 is enlarged, and the distance between the two adjacent small pieces of cardboard 6 is enlarged. At the same time, the small piece of cardboard 6 is located between two adjacent clips 210. When the cardboard 6 completely falls into the melting chamber 1003, the electric clamp 207 controls the two clamps 208 to move toward each other on the fixed shaft 209, so that the two clamps 208 squeeze the six clips 210 toward the middle, and the spring between the two adjacent clips 210 is compressed. The distance between the two adjacent clips 210 gradually decreases, and the small piece of cardboard 6 located between the two clips 210 is squeezed by the two adjacent inclined portions 21001. Since the inclined portion 21001 of each clip 210 is inclined to the left, Looking from the back to the front, the left clip 210 applies an upward force to the cardboard block 6 when squeezing the cardboard block 6, and the right clip 210 applies a downward force to the cardboard block 6 when squeezing the cardboard block 6, so that the cardboard block 6 is flipped clockwise, so that the upper surface of the cardboard block 6 faces the right clip 210, and the lower surface of the cardboard block 6 faces the left clip 210. As the two adjacent clips 210 continue to move toward each other, the two adjacent clips 210 clamp the corresponding cardboard block 6, and the cardboard block 6 is clamped by the clips 210. The cardboard pieces 6 are made to be perpendicular to the water surface. Compared with the cardboard pieces 6 being parallel to the water surface, when the cardboard pieces 6 sink downward, the contact area between the cardboard pieces 6 and the wax liquid on the water surface is small, thereby reducing the wax liquid attached to the surface of the cardboard pieces 6, thereby improving the collection efficiency of the wax liquid. In addition, the wax liquid melted from the inside of the cardboard 6 can float upward to the water surface after entering the water, thereby avoiding the cardboard pieces 6 blocking the wax liquid when it rises. At the same time, the hot water in the melting chamber 1003 flows from front to back, and the surface of the cardboard pieces 6 is flushed by the flowing hot water, thereby avoiding the residue of wax liquid on the surface of the cardboard pieces 6.

[0043] When the clamping plate 208 clamps the cardboard 6 small pieces so that the cardboard 6 small pieces are in a state of being vertical to the water surface, the driving member 206 is controlled to drive the electric clamp 207 and the connecting parts to move downward, so that the cardboard 6 small pieces quickly sink to the bottom of the melting chamber 1003, so that the cardboard 6 small pieces are quickly separated from the wax liquid on the upper side, so that the cardboard 6 small pieces are completely immersed in hot water, and the melting of the wax inside the cardboard 6 small pieces is accelerated. In the process of the cardboard 6 small pieces moving downward to the bottom of the melting chamber 1003, the clamping plate 208 is in a clamping state with the cardboard 6 small pieces, so that the cardboard 6 small pieces are all fitted with the adjacent clamping pieces 210, so there is a gap between two adjacent cardboard 6 small pieces, and Moreover, when two adjacent clips 210 are in a clamped state, the center distance between two adjacent scrapers 211 is equal to the center distance between two adjacent clips 210, so the scraper 211 is directly opposite to the gap between two adjacent cardboard pieces 6, and as the clip 210 drives the cardboard piece 6 to sink, the guide surface 21101 guides the cardboard piece 6 to be inserted between the two adjacent scrapers 211. At this time, the clip 210 is located at the rear side of the scraper 211. Since the distance between the facing surfaces of the two adjacent scrapers 211 is less than the thickness of the cardboard 6, the cardboard piece 6 is squeezed by the scraper 211, and then the electric slider 205 is controlled to move backward on the slide rail 204, thereby driving the driving member 206 and the electric clamp 206. 07 and its connecting parts move backward, so that the clamping piece 210 drives the small piece of cardboard 6 to move backward, and the scraper 211 continuously squeezes the cardboard 6, so that the wax liquid inside the cardboard 6 is quickly discharged, thereby improving the separation efficiency of the wax liquid and the cardboard 6, and the scraper 211 scrapes the surface of the cardboard 6, thereby scraping off the wax liquid remaining on the surface of the cardboard 6, thereby improving the collection efficiency of the wax liquid, as the clamping piece 210 drives the small piece of cardboard 6 to move to the rear side of the melting chamber 1003, at this time, the small piece of cardboard 6 is separated from the scraper 211, and then the electric clamp 207 is controlled to drive the two clamps 208 to move back to the initial position, so that the small pieces of cardboard 6 are scattered from each other, and the driving member 206 is controlled to drive the clamping piece 210 moves upward to the initial position, so that the clamping piece 210 is separated from the small piece of cardboard 6, and the small piece of cardboard 6 is soaked in the bottom of the rear side of the melting chamber 1003, so that the wax liquid remaining inside the small piece of cardboard 6 and the part clamped by the clamping piece 210 continue to melt, and at the same time, the electric slider 205 is controlled to move forward to the initial position, so as to facilitate clamping the subsequent cardboard 6, and so on. When a lot of cardboard 6 is accumulated on the rear side of the melting chamber 1003, the transmission of the cardboard 6 is first suspended, and then the wax liquid on the surface is brought to the recovery chamber 1004 by the hot water flowing in the melting chamber 1003, and then the cardboard 6 accumulated on the rear side of the melting chamber 1003 only needs to be taken out manually with a salvage tool, so as to facilitate the subsequent recovery of the cardboard 6.

[0044] In the process of the first fixed roller 2 and the second fixed roller 3 transmitting the cardboard 6, since the surface of the second fixed roller 3 is provided with spikes 3002, when the second fixed roller 3 rotates, the spikes 3002 are driven to rotate synchronously, so that the cardboard 6 is pierced by the spikes 3002, so that more through holes are left on the surface of the cardboard 6. When the cardboard 6 is immersed in hot water, the contact area between the cardboard 6 and the hot water is increased through the through holes, thereby increasing the melting speed of the wax inside the cardboard 6, and at the same time facilitating the discharge of the wax liquid in the cardboard 6 through the through holes, thereby improving the separation efficiency of the polyethylene wax and the cardboard 6.

[0045] Furthermore, in the process of the cardboard 6 being cut by the cutter ring 2001, the cutter ring 2001 and the second fixed roller 3 transfer the cardboard 6 through friction, so that wax is attached to the surface of the cutter ring 2001 and the surface of the second fixed roller 3, which is difficult to clean manually. Therefore, when it is necessary to clean the wax on the surface of the cutter ring 2001 and the surface of the second fixed roller 3, the surface of the cutter ring 2001 and the second fixed roller 3 are first controlled to stop rotating, and then hot water is transported to the right water supply connector 202 through the external circulating water supply device, so that the hot water is respectively The hot water flows into the first water delivery channel 2002 and the second water delivery channel 3003, and then the hot water is discharged from the left water supply connector 202 and flows back to the external circulating water supply device, so that the hot water is circulated in the first water delivery channel 2002 and the second water delivery channel 3003, so that the heat of the hot water is transferred to the surface of the cutter ring 2001 and the second fixed roller 3, so that the temperature of the surface of the second fixed roller 3 and the surface of the cutter ring 2001 increases, so that the wax remaining on the surface of the cutter ring 2001 and the surface of the second fixed roller 3 melts, and then the melted wax The wax drips downward into the melting chamber 1003. Compared with the conventional wax cleaning method, the cleaning efficiency of the cutter ring 2001 and the second fixed roller 3 is improved, and the workload of manual cleaning is reduced. Moreover, when the cutter ring 2001 and the second fixed roller 3 are transmitting and cutting the cardboard 6, hot water is circulated into the first water delivery channel 2002 and the second water delivery channel 3003, and the cardboard 6 is pre-dewaxed by the temperature of the surface of the cutter ring 2001 and the second fixed roller 3, so that the wax on the surface of the cardboard 6 is melted in advance, thereby improving the separation of the wax. On this basis, when hot water flows into the melting chamber 1003 from the inclined surface 1005, the second fixed roller 3 is arranged to be located on the upper side of the inclined surface 1005, so that the surface of the second fixed roller 3 is flushed with hot water, thereby flushing the wax on the surface of the second fixed roller 3 into the melting chamber 1003 for subsequent separation. Moreover, when the second fixed roller 3 stops rotating, the wax dripping from the surface of the second fixed roller 3 can be cleaned with hot water, thereby improving the cleaning effect of the second fixed roller 3.

[0046] In the process of water flow and wax liquid flowing through the surface of the cooling plate 4, the surface of the cooling plate 4 is made concave and convex, thereby reducing the speed of the water flow and wax liquid flowing through the cooling plate 4, thereby extending the cooling time of the water flow and wax liquid, allowing the wax liquid to fully solidify. In addition, compared with the cooling plate 4 being in a flat plate shape, the contact area with the water flow and wax liquid is increased, further allowing the wax liquid to fully solidify, thereby improving the recovery efficiency of the polyethylene wax.

[0047] Example 2

[0048] On the basis of Example 1, Figure 1 , Figure 7 and Figure 8 As shown, the suction system includes a support frame 301, an electric suction hood 302 and an air filter 303; two left-right symmetrical support frames 301 are fixedly connected to the fixed frame 1; an electric suction hood 302 is fixedly connected to the two support frames 301, and the electric suction hood 302 is located above the melting chamber 1003; the upper side of the electric suction hood 302 is connected to the air filter 303.

[0049] The air suction system also includes an air tank 304 and a hair dryer 305; the air tank 304 is connected to the air filter 303; a hair dryer 305 is arranged on the upper front part of the fixed frame 1, and the hair dryer 305 is opposite to the first fixed roller 2 and the second fixed roller 3; the air tank 304 and the hair dryer 305 are connected through a hose.

[0050] Since the temperature in the melting chamber 1003 is relatively high, water vapor is likely to appear during the soaking process of the paperboard 6. Furthermore, when the paperboard 6 contains some ink or other adhesive components, some volatile organic compounds will be released when the hot water is soaked in the paperboard 6. In order to prevent the volatile organic compounds from escaping and causing harm to the health of the staff, when the paperboard 6 is soaked, the electric suction hood 302 located on the support frame 301 is controlled to be turned on, so that the electric suction hood 302 sucks the air with a higher temperature above the melting chamber 1003, thereby sucking the water vapor and volatile organic compounds in the hot water into the electric suction hood 302, preventing the volatile organic compounds from escaping into the air, and preventing the staff from inhaling the volatile organic compounds and causing physical damage, and then the air filter 303 is used to filter the paperboard 6. The volatile organic compounds in the water vapor are filtered and sterilized, and then the filtered water vapor and high-temperature gas are transported to the gas storage tank 304. When the cardboard 6 is transmitted between the first fixed roller 2 and the second fixed roller 3, the hair dryer 305 is controlled to start working, so that the high-temperature gas and water vapor in the gas storage tank 304 are blown out from the hair dryer 305, and the high-temperature gas and water vapor are blown toward the first fixed roller 2 and the cardboard 6, so that the cardboard 6 is heated by the high-temperature gas and water vapor, and the temperature of the cardboard 6 is further increased, and the subsequent collection efficiency of the polyethylene wax is improved. At the same time, the high-temperature gas and water vapor are blown toward the first fixed roller 2, so that the impurities such as wax and paper scraps remaining on the surface of the cutter ring 2001 are cleaned, and the surface of the cutter ring 2001 is kept clean and smooth, thereby improving the cutting effect of the cutter ring 2001.
