Description

Technical Field

[0001] The present invention belongs to the technical field of resource recovery, and particularly relates to a paper-plastic separator. Background Art

[0002] Paper-plastic separation refers to separating some plastics containing paper, which is an environmental protection means for recycling paper. The wet separation method is a common means of paper-plastic separation. It mainly separates the crushed paper-plastic materials through friction. By filling a softening medium such as water, the paper is softened and then melted and separated from the plastic under the action of friction. The shredded pulp flows out from the small holes in the sieve, and the remaining plastic is discharged from a separation outlet. At present, in order to meet the high-volume processing requirements, the general separator is often large in size. Since the speed space of friction and feeding is fixed, whether the separation rate meets the standard often depends on the separation space length of the equipment. However, in some small places, it is easy to have the problem that the equipment occupies too much space and it is difficult to adjust the friction and feeding separately according to the state characteristics of the paper-plastic materials. Summary of the Invention

[0003] The purpose of the present invention is to provide a paper-plastic separator to solve the problems mentioned in the background art.

[0004] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows: A paper-plastic separator includes a bracket and a separation barrel. The separation barrel is arranged on the bracket in a horizontal state. The upper and lower sides of the separation barrel are respectively provided with a feed inlet and a slag discharge port relatively. A recovery hopper communicating with the inner cavity is arranged in the middle of the lower side of the separation barrel. A spray head communicating with an external water source is arranged on the upper side in the separation barrel. A separation mechanism is arranged in the separation barrel; The separation mechanism includes a paper rubbing assembly, a spiral guide vane and a sieve. The sieve is integrally in a cylindrical structure and is fixedly arranged in the separation barrel with an empty window at the feed inlet. The paper rubbing assembly and the spiral guide vane are respectively arranged in the separation barrel from the inside to the outside along the axis of the separation barrel. The driving ends of the paper rubbing assembly and the spiral guide vane are respectively arranged at both ends of the separation barrel and are in transmission connection with an external transmission device; The paper rubbing assembly includes a roller and a paper rubbing knife group. The roller is integrally hollow. The number of the paper rubbing knife groups is several and they are evenly arranged on the roller. The paper rubbing knife group is composed of several floating paper rubbers evenly distributed along the axis of the roller. The floating paper rubbers are slidably and sealingly connected to the side perpendicular to the axis of the roller. The position of the paper rubbing knife group corresponds to and matches that of the spiral guide vane.

[0005] The roller is provided with an installation cavity matching the material rubbing knife group. The floating paper rubbing device is composed of a floating plate and a spring. The floating plate is slidably and sealingly connected to the installation cavity. The spring is arranged between the lower end of the floating plate and the bottom wall of the installation cavity. The adjacent floating plates are slidably and sealingly connected. One end of the floating plate facing the forward rotation direction of the spiral guide piece is an inclined surface.

[0006] The inclined surface end of the floating plate is in a spiral inclination state from top to bottom, and the inclination direction is the same as the spiral direction of the spiral guide piece.

[0007] The sieve holes of the sieve mesh are distributed below the horizontal line of the axis of the sieve mesh.

[0008] A main shaft is arranged in the middle of the roller. The main shaft rotates and seals through the separation barrel. Both ends of the spiral guide piece are provided with connecting rings.

The plug body is slidably and sealingly arranged in the stepped cavity. The connecting rod is connected to the plug body and extends out of the stepped cavity and then is connected to the synchronous plate.

[0010] A U-shaped oil passage is opened in the middle of the main shaft. One end of the U-shaped oil passage is located outside the separation barrel. A plurality of branch oil passages communicating with the hollow part of the separation barrel are evenly opened on the side of the separation barrel. The plurality of branch oil passages correspond to the plurality of paper rubbing components one by one.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1: Figures 1-6 As shown, a paper-plastic separator comprises a support 1 and a separation barrel 2. The separation barrel 2 is arranged on the support 1 and is in a horizontal state. A feed inlet 21 and a slag discharge outlet 22 are arranged on the upper and lower sides of the separation barrel 2, respectively. A recovery hopper 23 connected to the inner cavity is arranged in the middle of the lower side of the separation barrel 2. A nozzle connected to an external water source is arranged on the upper side of the separation barrel 2. A separation mechanism is arranged in the separation barrel 2. The separation mechanism includes a paper picking assembly, a spiral guide sheet 3 and a screen 4. The screen 4 is a cylindrical structure as a whole and is fixedly arranged in the separation barrel 2 and has a window at the feed inlet 21. The paper picking assembly and the spiral guide sheet 3 are respectively arranged in the separation barrel 2 from the inside to the outside along the axis of the separation barrel 2. The transmission ends of the paper picking assembly and the spiral guide sheet 3 are respectively arranged at both ends of the separation barrel 2 and are transmission-connected to an external transmission device. The paper feeding assembly includes a roller 5 and a paper feeding knife group. The roller 5 is hollow as a whole. The number of the paper feeding knife groups is several and they are evenly arranged on the roller 5. The paper feeding knife group is composed of several floating paper feeders evenly distributed along the axial direction of the roller 5. The floating paper feeders are slidably and sealingly connected to the side of the roller 5 in the direction perpendicular to the axis. The position of the paper feeding knife group corresponds to and matches that of the spiral guide vane 3.

[0023] During the paper-plastic separation process, an external water source uses a water pump to pump water, and then it is input into the separation barrel 2 through a spray head arranged on the upper side inside the separation barrel 2. The material to be separated is input into the separation barrel 2 through the feed inlet 21. At this time, an external transmission component such as a motor or a belt pulley drives the separation mechanism to rotate. When the paper feeding assembly rotates, the rotation of the roller 5 will drive and rub the material between the roller 5 and the screen 4 inside the separation barrel 2 by using the paper feeding knife group on the roller 5. Combined with the softening of the paper by water, the paper and the plastic are separated. Finally, the screen 4 blocks the plastic, and the melted paper passes through the screen and is discharged from the recovery hopper 23, while the separated plastic is discharged through the slag discharge port 22. During the paper feeding and separation process, the rotation direction of the spiral guide vane 3 is opposite to that of the entire roller 5. Since the paper feeding knife group on the roller 5 is composed of several floating paper feeders, when the spiral guide plate abuts against the floating paper feeder, it will cause the floating paper feeder to produce a telescopic action. On the one hand, it can act as an avoidance action with the spiral guide plate, and on the other hand, the telescopic action of the floating paper feeder can produce a pushing action on the material, which can further improve the separation effect. In this way, the paper feeding does not affect the conveying and discharging of the material, and the paper feeding power and the conveying speed of the material can be separately adjusted by controlling the paper feeding assembly and the spiral guide vane 3 respectively. It is especially suitable for environments where the processing site is small and the length of the separator is insufficient. In this way, the number of secondary separations and the separation rate of a single separation can be reduced, which is more conducive to the processing requirements. The water pump for supplying external water source, the power components such as motors for driving the separation mechanism, and the control devices required for the starting device, such as tablet computers, control boxes with specific logic circuits, computers or switches, mentioned in this application are all common prior art devices in the prior art field. For example, the transmission of the motor can adopt direct transmission or belt pulley transmission. In this application, these technical features are not the technical problems to be solved by this application, but as the necessary content required to implement this application, only a simple technical interpretation is made here and no more technical details are elaborated, but it does not mean that those skilled in the art cannot use relevant or similar devices to implement or that those skilled in the art cannot implement.

[0024] The roller 5 is provided with an installation cavity 51 that matches the material rubbing knife group. The floating paper rubbing device consists of a floating plate 52 and a spring 53. The floating plate 52 is slidably and sealingly connected to the installation cavity 51. The spring 53 is arranged between the lower end of the floating plate 52 and the bottom wall of the installation cavity 51. The adjacent floating plates 52 are slidably and sealingly connected. One end of the floating plate 52 facing the advancing direction of the spiral guide piece 3 is an inclined surface 54.

[0025] The inclined surface 54 end of the floating plate 52 is in a spiral inclination state from top to bottom, and the inclination direction is the same as the spiral direction of the spiral guide piece 3.

[0026] The spring 53 in the floating paper rubbing device is used to support and connect the floating plate 52, so that it always maintains a state of protruding from the installation cavity 51 to be able to push the material for paper-plastic separation. When the floating plate 52 is pushed by the spiral guide piece 3, it retracts downward into the installation cavity 51 under the guidance of the inclined surface 54 of the floating plate 52 to achieve an avoidance effect and then reset. To limit the displacement stroke and distance of the floating plate 52, corresponding guide ribs can be set in the installation cavity 51 to further limit the floating plate 52. The inclined surface 54 of the floating plate 52 is in a spiral structure of inclined torsion state, which can better match the movement guiding and pushing effect of the spiral guide piece 3, reduce the abutting friction between the floating plate 52 and the spiral guide piece 3, and improve the guiding property; At the same time, due to the guiding effect of the inclined surface 54 of the floating plate 52, compared with the straight floating plate 52 structure, it is easier to generate pushing force on the material rather than guiding friction. It can further guide the material in the separation barrel 2 to move towards the end of the floating plate 52 and improve the friction effect.

[0027] The sieve holes of the sieve mesh 4 are distributed below the horizontal line of the axis of the sieve mesh 4.

[0028] This can reduce the entry of water, pulp, impurities, etc. into the upper side of the separation barrel 2, resulting in an increase in subsequent cleaning time and area.

[0029] A main shaft 6 is provided in the middle of the roller 5. The main shaft 6 rotates and seals through the separation barrel 2. Connecting rings 61 are provided at both ends of the spiral guide piece 3. One of the connecting rings 61 is rotatably and sealingly sleeved on the main shaft 6 and extends out of the separation barrel 2. Driving belt wheels 62 are respectively provided at the opposite ends of the main shaft 6 and the connecting ring 61.

[0030] The main shaft 6 plays a role in supporting the entire paper rubbing assembly, and the spiral guide piece 3 and the two connecting rings 61 cooperate to form an integral support. The main shaft 6 and one of the connecting rings 61 are rotatably sleeved, which can improve the support stability between the main shaft 6 and the connecting ring 61. The driving belt wheels 62 are respectively provided on the main shaft 6 and the connecting ring 61 on the opposite side. In this way, corresponding transmission devices can be set on both sides of the entire device for independent control to meet the needs of different production parameter adjustments.

[0031] The screen 4 is evenly provided with a number of abrasive strips 8 that match the material rubbing knife group.

[0032] This can enable the paper rubbing assembly to make the material generate a better frictional pushing action when passing through the abrasive strip 8, improving the effect of paper rubbing.

[0033] Embodiment 2: As Figures 2-4 shown, it is a further improvement based on Embodiment 1. The material rubbing knife group further includes a regulator. The regulator includes a synchronous plate 7 and a number of piston parts. The synchronous plate 7 is slidably and sealingly arranged at the inner bottom of the installation cavity 51. A spring 53 is arranged at the upper end of the synchronous plate 7. The piston parts are evenly distributed along the length direction of the roller 5. The piston part includes a plug cylinder 71, a plug body 72 and a connecting rod 73. The plug cylinder 71 is integrally formed with the roller 5 and is provided with a stepped cavity 74 communicating with the installation cavity 51. The plug body 72 is slidably and sealingly arranged in the stepped cavity 74. The connecting rod 73 is connected to the plug body 72 and extends out of the stepped cavity 74 and then is connected to the synchronous plate 7.

[0034] A U-shaped oil passage 75 is opened in the middle of the main shaft 6. One end of the U-shaped oil passage 75 is located outside the separation barrel 2. A number of oil distribution passages 76 communicating with the hollow part of the separation barrel 2 are evenly opened on the side of the separation barrel 2. The number of oil distribution passages 76 corresponds to the number of paper rubbing assemblies one by one. The oil distribution passages 76 are connected to the lower end oil passages of the plug cylinders 71 of the regulators at corresponding positions through oil pipes, so that the hydraulic oil fills the space between the lower end of the stepped cavity 74 and the lower end of the plug body 72. The bracket 1 is fixedly provided with an oil distribution cover 77 that is rotatably sleeved with the main shaft 6 and corresponds to the U-shaped oil passage 75.

[0035] Furthermore, in order to meet different types of paper-plastic materials, such as some paper-plastic waste will be smaller in volume or in a non-belt structure during crushing and recycling. Therefore, at this time, the hydraulic oil in the oil distribution cover 77 can be pumped, so that the hydraulic oil is input into the U-shaped oil passage 75 through the oil distribution cover 77, and finally is input into the regulator through a number of oil distribution passages 76 connected to the U-shaped oil passage 75 to realize the adjustment of the material rubbing knife group; Among them, when the hydraulic oil is input, the hydraulic oil in the plug cylinder 71 of the regulator increases, thereby pushing the plug body 72 to move upward, and the whole synchronous plate 7 is pushed to move upward through the connecting rod 73, so that the position of the whole group of material rubbing knife groups moves upward. Since the highest position of the floating plate 52 is restricted by the guiding ribs, after reaching the maximum height position, only the spring 53 is compressed and adjusted. In this way, after the protruding height of the floating plate 52 rises, the interval between the floating plate 52 and the screen 4 can be reduced, so as to achieve the effect of increasing the frictional force applied to the material pushing or meet the needs of some materials with smaller volume; On the contrary, when the hydraulic oil is pumped out, the height position of the floating plate 52 will drop under the influence of negative pressure, so as to meet the separation needs of some materials with larger volume. At the same time, since the oil distribution cover 77 is sleeved around the main shaft 6, the oil distribution cover 77 itself does not affect the transmission of the main shaft 6, and the regulator in the separation barrel 2 is not affected during rotation.

[0036] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
