Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-4 The present invention provides a technical solution: a device for removing water and iron from recycled plastic granules of waste household appliances, comprising a housing 1, wherein a support film 2 in a bent and folded state is arranged inside the housing 1, and an adsorption film 3 in a bent and folded state is sleeved on the outside of the support film 2. The support film 2 and the adsorption film 3 are connected by multiple iron removal components 9, so that the bent and folded state of the adsorption film 3 is basically consistent with the bent and folded state of the support film 2; one end of the support film 2 is attached to and wrapped around the outside of a guide block 4, the guide block 4 is located on the inner wall of the housing 1, and the guide block 4 has a T-shaped structure, and each corner of the guide block 4 is provided with a rounded chamfer; the ends of the support film 2 and the adsorption film 3 away from the guide block 4 are clamped by a clamping component 5 and formed into a sealed state.

[0029] An exhaust component 6 is provided below the adsorption membrane 3. The exhaust component 6 is used to spray gas onto the adsorption membrane 3 and agitate the adsorption membrane 3, thereby simultaneously agitating the supporting film 2. The supporting film 2 is made of plastic or rubber, while the adsorption membrane 3 is made of cotton fabric.

[0030] The inner side of the supporting film 2 and the guide block 4 form a receiving cavity 21 for placing plastic particles. The top of the receiving cavity 21 is open. The top opening of the receiving cavity 21 is used to add the plastic particles to be processed into the receiving cavity 21. To facilitate the addition and guidance of the plastic particles, a feeding hopper 7 is provided near the middle position of the top opening of the receiving cavity 21. The feeding hopper 7 is fixed on the inner wall of the box body 1.

[0031] Please see Figure 5 Both the support film 2 and the adsorption film 3 have multiple small holes 8, and the small holes 8 on the support film 2 and the adsorption film 3 are staggered from the position of the iron removal component 9. The diameter of the small holes 8 is much smaller than the minimum diameter or width of the plastic particles.

[0032] Please see Figure 6 The iron removal assembly 9 includes a first retaining ring 91 and a second retaining ring 92, which are detachably connected. Preferably, the first retaining ring 91 and the second retaining ring 92 form a snap-fit ​​connection, that is, the first retaining ring 91 and the second retaining ring 92 are male and female snap-fit ​​parts respectively. In addition, the first retaining ring 91 and the second retaining ring 92 can also be threaded.

[0033] The first buckle 91 is fixed to the supporting film 2. The end of the first buckle 91 away from the second buckle 92 extends into the cavity 21 with a length of 1-3mm. The end of the second buckle 92 away from the first buckle 91 is fixed to the inner side of the adsorption film 3, which can be fixed by adhesive bonding. The first buckle 91 has a first guide hole 911 coaxially arranged inside, which passes through both ends of the first buckle 91. The second buckle 92 has a mounting hole 922 and a second guide hole 921 coaxially arranged inside. The mounting hole 922 and the second guide hole 921 pass through both ends of the second buckle 92, respectively. The mounting hole 922 passes through the end of the second buckle 92 closest to the first buckle 91, and the two ends of the mounting hole 922 are connected to the first guide hole 911 and the second guide hole 921, respectively. A strong magnetic column 93 is placed inside the mounting hole 922. The strong magnetic column 93 is used to adsorb small iron particles adsorbed and bonded to the plastic particles.

[0034] Both the first guide hole 911 and the second guide hole 921 are frustum-shaped holes. The inner diameter of the end of the first guide hole 911 adjacent to the second retaining ring 92 is smaller than the inner diameter of the end of the first guide hole 911 away from the second retaining ring 92, and the large diameter end of the first guide hole 911 is much smaller than the minimum diameter or width of the plastic particles to be processed; the inner diameter of the end of the second guide hole 921 adjacent to the first retaining ring 91 is smaller than the inner diameter of the end of the second guide hole 921 away from the first retaining ring 91; that is, the large diameter end of the first guide hole 911 faces the receiving cavity 21, and the large diameter end of the second guide hole 921 faces the inner side of the adsorption membrane 3; The minimum inner diameter of the first guide hole 911 and the second guide hole 921 is smaller than the inner diameter of the mounting hole 922. The minimum inner diameter of the first guide hole 911 and the second guide hole 921 is also smaller than the diameter of the strong magnetic column 93. At the same time, the diameter of the strong magnetic column 93 is set to be smaller than the inner diameter of the mounting hole 922, and the height of the strong magnetic column 93 is smaller than the depth of the mounting hole 922. When the first buckle 91 and the second buckle 92 are spliced, the magnetic column is limited due to the blocking effect at both ends of the mounting hole 922. When the first buckle 91 and the second buckle 92 are separated, it is convenient to remove and place the magnetic column.

[0035] See Figures 1-6Since the exhaust assembly 6 sprays gas onto the adsorption membrane 3, thus agitating the adsorption membrane 3, the agitation of the adsorption membrane 3 facilitates the agitation of the supporting film 2. When plastic particles are added to the supporting film 2, the agitation helps to ensure that the plastic particles are more evenly distributed in the receiving cavity 21. Secondly, since the gas enters the receiving cavity 21 through the small holes 8 on the adsorption membrane 3 and the supporting film 2 during the gas spraying process of the exhaust assembly 6, the agitation of the plastic particles facilitates the drying of the plastic, thereby improving the dehydration and drying effect. In addition, since the first Both the first guide hole 911 and the second guide hole 921 are frustum structures. The large diameter end of the first guide hole 911 faces the receiving cavity 21, and the large diameter end of the second guide hole 921 faces the inner side of the adsorption membrane 3. Utilizing the guiding effect of the frustum structure, under the influence of disturbance, it is also convenient for small iron particles on the plastic granules to be adsorbed onto the strong magnetic column 93 through the first guide hole 911, and to drive the strong magnetic column 93 to move inside the mounting hole 922. This facilitates the falling of iron particles that have accumulated on the strong magnetic column 93 into the second guide hole 921, thereby improving the adsorption and iron removal effect.

[0036] In addition, the adsorption membrane 3 is made of cotton cloth, which facilitates the absorption of water vapor and the adhesion of iron particles.

[0037] See Figure 2 , Figure 3 , Figures 7-8 The clamping assembly 5 includes a first clamping piece 52 and a second clamping piece 55. A connecting rod 51 connects the first clamping piece 52 to the inner wall of the housing 1, and the first clamping piece 52 is vertically arranged. A limiting screw 53 is vertically fixed on the first clamping piece 52. The limiting screw 53 passes through the through hole 10 provided at the corner of the supporting film 2 and the adsorption film 3. The second clamping piece 55 is sleeved on the outside of the limiting screw 53. A limiting nut 54 is sleeved on the outside of the limiting screw 53. The limiting nut 54 and the limiting screw 55 are connected to the limiting screw 53. The positioning screw 53 is connected by a threaded engagement. The first clamping piece 52 and the second clamping piece 55 are used to clamp the two sides of the adsorption film 3 away from the guide block 4. The positions of the first clamping piece 52 and the second clamping piece 55 are aligned, and the position of the limiting nut 54 on the limiting screw 53 is adjusted to press the second clamping piece 55 close to the first clamping piece 52, thereby clamping the supporting film 2 and the adsorption film 3 away from the guide block 4, so that the supporting film 2 and the adsorption film 3 are in a sealed state away from the guide block 4.

[0038] When the limiting nut 54 is unscrewed and the second clamping piece 55 is removed, the clamping of the supporting film 2 and the adsorption film 3 at the end away from the guide block 4 can be released. Furthermore, by removing the supporting film 2 and the adsorption film 3 from the limiting screw 53, the end of the supporting film 2 and the adsorption film 3 away from the guide block 4 can be separated from the clamping assembly 5.

[0039] A limiting groove 41 is provided at the middle position of the side of the guide block 4, and the limiting groove 41 is set along the outline of the guide block 4; an elastic strip 22 is inserted inside the limiting groove 41, and the elastic strip 22 is made of rubber; the outer side of the elastic strip 22 is connected to the inner side of the supporting film 2.

[0040] The two ends of the elastic strip 22 are adjacent to the top of the guide block 4, and the two ends of the elastic strip 22 are detachably mounted on the guide block 4 by a screw 42. Specifically, the screw 42 penetrates the elastic strip 22 and is connected to the guide block 4 through a threaded connection. The two ends of the elastic strip 22 are fixed to the guide block 4 by the two screws 42, thereby limiting the entire elastic strip 22 in the limiting groove 41, so that the supporting film 2 is attached and wrapped around the outside of the guide block 4. At the same time, by unscrewing the two screws 42, the elastic strip 22 can be disassembled, thereby disassembling one end of the supporting film 2. And when the supporting film 2 and the adsorption film 3 are separated from the clamping assembly 5 at the end away from the guide block 4, the supporting film 2 and the adsorption film 3 can be disassembled as a whole.

[0041] See Figure 1 , Figure 2 and Figures 9-11 The exhaust assembly 6 includes a support base 61 disposed on the outer wall of one side of the housing 1. A sealing plate 63 is movably disposed on the support base 61. Specifically, the bottom of the support base 61 and the sealing plate 63 are connected by a linear guide rail. An inlet and outlet 12 are disposed on the side of the housing 1 where the support base 61 is disposed. The sealing plate 63 passes through the inside of the inlet and outlet 12. An adjustment assembly 64 is also disposed on the support base 61. The adjustment assembly 64 is used to adjust the sealing plate 63 to move into the inlet and outlet 12 and just close the inlet and outlet 12.

[0042] The inner side of the sealing plate 63 is provided with two supports 651. A sleeve 65 passes through the interior of each support 651, and a gas guide hose 62 passes through the interior of each sleeve 65. The gas guide hoses 62 are fixed inside the sleeves 65 by adhesive bonding and are used to connect to an external air source. Specifically, the two gas guide hoses 62 are used to connect to the two exhaust outlets of the same air pump to introduce gas at the same pressure. Each sleeve 65 is provided with a compression port 652, and a cam 66 is correspondingly provided on one side of each compression port 652. During the rotation of wheel 66, the air guide hoses 62 corresponding to the two extrusion ports 652 are squeezed respectively, resulting in a change in the pressure of the gas discharged from the air guide hoses 62. At the same time, the installation angles of the two cams 66 are different, so the pressure changes of the gas discharged from the two air guide hoses 62 are also different. The two air guide hoses 62 are located below the adsorption membrane 3. By spraying gas with changing pressure to both sides of the bottom of the adsorption membrane 3, it is easy to disturb the adsorption membrane 3 to make irregular fluctuations, thereby improving the irregular disturbance effect on the plastic particles inside the supporting film 2, which helps to improve the water and iron removal effect.

[0043] Below each of the two cams 66, a support plate 631 is respectively provided, located inside the sealing plate 63. A rotating shaft 67 passes through the interior of each of the two cams 66, and the two rotating shafts 67 are rotatably connected to the two support plates 631. The bottom ends of the two rotating shafts 67 penetrate the two support plates 631, and each rotating shaft 67 is fitted with a pulley 671, which is connected by a belt 69. A drive motor 68 is installed on one side of the bottom of the sealing plate 63, and the output end of the drive motor 68 is connected to the bottom end of one of the rotating shafts 67. The drive motor 68 drives the rotating shaft 67 connected to it to rotate. Under the action of the belt 69 and the pulley 671, the two rotating shafts 67 rotate synchronously, thereby driving the rotation of the two cams 66 and achieving a cyclic compression effect on the two air guide hoses 62.

[0044] The adjusting assembly 64 includes an adjusting motor 641 mounted on a support base 61. An adjusting screw 642 is connected to the output end of the adjusting motor 641. The adjusting screw 642 is movably connected to the support base 61 via a bearing. A threaded sleeve 643 is threaded onto the outside of the adjusting screw 642, and the threaded sleeve 643 is connected to the sealing plate 63. Therefore, by rotating the adjusting screw 642 via the adjusting motor 641, the threaded sleeve 643 is moved, thereby moving the sealing plate 63 into the inlet / outlet 12 and sealing the inlet / outlet 12. In the closed state, by unscrewing the limiting nut 54 and the screw 42 near the limiting nut 54, and removing the second clamping piece 55, the elastic strip 22 can easily detach from the limiting groove 41 under the gravity of the plastic particles, and one corner of the supporting film 2 and the adsorption film 3 can detach from the limiting screw 53 (if one corner of the supporting film 2 and the adsorption film 3 does not detach from the limiting screw 53 in time, it can be manually pushed out). Therefore, it is convenient for the plastic particles to fall into the box 1 after water removal and removal of small iron particles, which is convenient for subsequent collection and processing.

[0045] To facilitate the subsequent collection of processed plastic granules, a sealing door 11 is movably installed on one side of the container 1. The sealing door 11 can be opened and closed, specifically by using a hinged mechanism with a door lock. Opening the sealing door 11 facilitates the subsequent collection and processing of the plastic granules inside the container 1. After the plastic inside the container 1 has been processed, the sealing plate 63 is reset by adjusting the motor 641. Figure 2 or Figure 10 The state shown.

[0046] Working principle: Plastic granules to be processed are fed into the receiving cavity 21 through the feed hopper 7. Simultaneously, gas is injected into the bottom of the adsorption membrane 3 through the air guide hose 62. The drive motor 68 drives the rotating shaft 67 connected to it to rotate. Under the action of the belt 69 and pulley 671, the two rotating shafts 67 rotate synchronously, thereby driving the rotation of the two cams 66 to achieve a cyclic squeezing effect on the two air guide hoses 62. During the rotation of the cams 66, the air guide hoses 62 corresponding to the two squeezing ports 652 are squeezed respectively, thus causing the gas pressure discharged from the air guide hoses 62 to change. At the same time, the installation angle of the two cams 66 changes. Because the pressure changes of the gas discharged from the two air guide hoses 62 are different, the adsorption membrane 3 is disturbed and fluctuates irregularly, thereby improving the irregular disturbance effect on the plastic particles inside the supporting membrane 2. Through the disturbance effect, firstly, it is easier to make the plastic particles more evenly distributed in the receiving cavity 21; secondly, it is easier to improve the dehydration and drying effect of the plastic particles; in addition, it is easier for small iron particles on the plastic particles to be adsorbed onto the strong magnetic column 93 through the first feed hole 911, and through the second feed hole 921, it is easier for a large number of iron particles accumulated on the strong magnetic column 93 to fall into the second feed hole 921, thereby improving the adsorption and iron removal effect.

[0047] The water and iron removal device of the present invention performs water and iron removal simultaneously. The adsorption membrane 3 is made of cotton cloth, which is convenient for absorbing water vapor and for the adhesion of iron particles. After a suitable treatment time, the gas is stopped from being introduced into the air guide hose 62, and the adjusting screw 642 is rotated by the adjusting motor 641, thereby moving the threaded sleeve 643. This moves the sealing plate 63 into the inlet and outlet 12 and just closes the inlet and outlet 12. In this state, by unscrewing the limiting nut 54 and the screw 42 on the side near the limiting nut 54, and removing the second clamping piece 55, the elastic strip 22 is disengaged from the limiting groove 41, and one corner of the supporting film 2 and the adsorption membrane 3 is disengaged from the limiting screw 53. At this time, after water removal and removal of small iron particles, the plastic particles fall into the box 1, which is convenient for subsequent collection and treatment.

[0048] By unscrewing the two screws 42, the elastic strip 22 can be disassembled, thereby disassembling one end of the supporting film 2. After the supporting film 2 and the adsorption film 3 are separated from the clamping assembly 5 at the end away from the guide block 4, the supporting film 2 and the adsorption film 3 can be disassembled. Since the first buckle 91 and the second buckle 92 are detachable, and the strong magnetic column 93 is easily removed after the first buckle 91 and the second buckle 92 are separated, it is convenient to clean the supporting film 2 and the small iron particles adsorbed on the adsorption film 3 and the strong magnetic column 93.
