Description

Technical Field

[0001] The invention belongs to the technical field of silica gel waste recycling, in particular to a silica gel processing waste collection device. Background Art

[0002] In the production process of silicone products, some burrs and bad silicone materials are produced, which are called waste. These waste rubber materials are not simply abandoned and landfilled, but recycled by special waste recycling companies, thus avoiding the burden of these wastes on the environment.

[0003] With the growth of silicone product production and consumption, the amount of silicone production waste and processing waste is also considerable. The generation of these wastes not only occupies a lot of factory space, but also pollutes the environment and leads to rising costs. Therefore, recycling these waste silicones is of great significance to reducing environmental pollution and improving product economic benefits.

[0004] Among them, physical crushing is the most common method for recycling silica gel waste. It mainly crushes the recycled waste and makes it into granular silica gel powder, which is then used as filler to achieve the purpose of reducing product cost, power consumption and modification.

[0005] However, since the collected silicone wastes are of different sizes, there will be differences in the degree of crushing of the wastes during the crushing process. Large silicone wastes will be crushed unevenly, and small silicone wastes will be over-crushed. Summary of the invention

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] Embodiment 1:

[0049] like Figures 1 to 10 As shown, a silica gel processing waste collection device according to the present invention comprises a recovery bin 1; a support frame is installed at the bottom of the recovery bin 1;

[0050] A material guide bin 3511 is installed at the bottom of the recovery bin 1; a screen drum 2 is rotatably connected inside the recovery bin 1, and a plurality of rows of evenly arranged screen holes 21 are provided on the screen drum 2; both ends of the screen drum 2 are installed with ring plates, namely a first ring plate 22 and a second ring plate 23;

[0051] A first motor 12 is installed on the right side wall of the recovery bin 1; a knife shaft 13 is installed on the first motor 12, and the knife shaft 13 passes through the first ring plate 22 and extends to the inside of the screen drum 2; and evenly arranged cutters 14 are spirally installed on the knife shaft 13;

[0052] A material guide mechanism is installed on the left side wall of the recovery bin 1, and the material guide mechanism is used to guide the silica gel waste into the screen cylinder 2;

[0053] The two end portions of the screen drum 2 are fixedly connected to the limit rings 24, and the limit rings 24 rotate in the recovery bin 1; the top of the screen drum 2 is provided with an active roller 25, and the active roller 25 is located between the two limit rings 24;

[0054] A driving rod 26 is installed in the active roller 25; a second motor 15 is installed above the first motor 12, and the driving shaft of the second motor 15 extends into the recovery bin 1 and is fixedly installed with the driving rod 26;

[0055] The outer ring surface of the active roller 25 is fixedly connected with multiple rows of evenly arranged insertion rods 27; a row of insertion rods 27 close to the screen cylinder 2 is inserted into a row of screen holes 21 of the screen cylinder 2;

[0056] Specifically, when processing the silicone waste, first control the first motor 12 to rotate, the first motor 12 will drive the knife shaft 13 and the cutter 14 on the knife shaft 13 to circulate and rotate in the screen drum 2, and then use the material guide mechanism to guide the silicone waste into the screen drum 2. When the silicone waste enters the screen drum 2, the circularly rotating cutter 14 will cut the silicone waste. In the process of the cutter 14 continuously cutting the silicone waste, the silicone waste will be gradually broken. When the particle size of the crushed silicone waste is smaller than the inner diameter of the screen hole 21, the silicone waste smaller than the inner diameter of the screen hole 21 will fall from the screen hole 21 and fall into the material guide bin 3511. Then, the fallen silicone waste can be collected by using a container.

[0057] More specifically, in the process of crushing the silicone waste, the second motor 15 is also controlled to rotate, and the direction of the second motor 15 is the same as that of the first motor 12, so the second motor 15 will drive the active roller 25 to rotate, and the rotating active roller 25 will drive the multiple rows of plug rods 27 to rotate cyclically. During the rotation of the plug rods 27, the rotating multiple rows of plug rods 27 will be inserted into the multiple rows of sieve holes 21 in sequence, thereby driving the sieve drum 2 to rotate cyclically in the recovery bin 1. At the same time, when the plug rods 27 are inserted into the sieve holes 21 in sequence, the sieve holes 21 will be dredged, thereby preventing the silicone waste from being blocked in the sieve holes 21, thereby affecting the feeding process of the sieve holes 21;

[0058] Furthermore, since the first motor 12 and the second motor 15 have the same direction of rotation, when the insertion rod 27 is used to push the screen drum 2 to rotate, the rotation direction of the screen drum 2 is opposite to the rotation direction of the cutter 14. Therefore, during the rotation of the screen drum 2, the silicone waste will be lifted to a certain height by the screen drum 2 due to the centrifugal force and friction force, and then fall under the gravity of the silicone waste itself. The falling silicone waste will act on the rotating cutter 14, thereby improving the contact degree between the silicone waste and the cutter 14, thereby improving the cutting effect of the silicone waste and accelerating the crushing efficiency of the silicone waste.

[0059] By setting the sieve cylinder 2, when the particle size of the crushed silicone waste is smaller than the inner diameter of the sieve hole 21, the silicone waste smaller than the inner diameter of the sieve hole 21 will fall from the sieve hole 21. In this process, the silicone waste smaller than the aperture of the sieve hole 21 can be discharged in time, thereby avoiding excessive crushing of the silicone waste. At the same time, the silicone waste larger than the sieve hole 21 will continue to be cut by the cutter 14, thereby avoiding uneven cutting of the silicone waste.

[0060] Embodiment 2:

[0061] The material guiding mechanism comprises a feeding cylinder 3;

[0062] A circular groove 16 is provided on the left side wall of the recovery bin 1, and the feed cylinder 3 passes through the circular groove 16 and is inserted into the second ring plate 23; the second ring plate 23 is fixedly installed in the screen cylinder 2; the feed cylinder 3 is rotatably connected in the second ring plate 23;

[0063] The feed barrel 3 is provided with two leakage hole groups, namely a first leakage hole group 31 and a second leakage hole group 32; the distance between the center positions of the two leakage hole groups is 120 degrees; the leakage hole size of the first leakage hole group 31 is larger than the leakage hole size of the second leakage hole group 32;

[0064] The portion of the feed tube 3 between the first leakage hole group 31 and the second leakage hole group 32 is intact;

[0065] A first C-shaped cylinder 33 is provided on the top of the feed cylinder 3, and the opening of the first C-shaped cylinder 33 faces downward and is fixed to the side wall of the recovery bin 1; the feed cylinder 3 is located inside the first C-shaped cylinder 33 and fits with the first C-shaped cylinder 33, and the first leakage hole group 31 is located in the opening of the first C-shaped cylinder 33 in the initial state;

[0066] A feed trough 34 is provided on the side of the first C-shaped cylinder 33 away from the recovery bin 1; a bin 35 is installed on the top of the feed trough 34; an end plate 36 is fixedly connected to the side of the bin 35 away from the recovery bin 1;

[0067] A second C-shaped cylinder 37 is disposed inside the first C-shaped cylinder 33, and the opening of the second C-shaped cylinder 37 faces upward and is aligned with the feed slot 34; the second C-shaped cylinder 37 is partially inserted into the feed cylinder 3; the second C-shaped cylinder 37 is fixedly connected to the end plate 36 on one side close to the end plate 36;

[0068] The end plate 36 is fixedly connected with a third motor 38; the third motor 38 is mounted with an auger 39, and the auger 39 passes through the second C-shaped cylinder 37 and extends into the feed cylinder 3;

[0069] In this embodiment, between the two leakage hole groups and the second ring plate 23, evenly arranged tooth grooves 4 are provided on the outer ring surface of the feed tube 3, and the tooth grooves 4 are long strip-shaped;

[0070] A gear 41 is rotatably connected to the side wall of the recovery bin 1 below the feed barrel 3, and the gear 41 is meshed with the tooth groove 4; the gear 41 is driven by a fourth motor 42, and the fourth motor 42 is installed on the side wall of the recovery bin 1;

[0071] In this embodiment, a collection bin 43 is installed below the feed cylinder 3;

[0072] Specifically, when the silicone waste is introduced into the screen cylinder 2, the silicone waste is first poured into the silo 35, and the silicone waste in the silo 35 will fall into the second C-type cylinder 37, and then the third motor 38 is controlled to drive the auger 39 to rotate slowly, and the auger 39 will push the silicone waste in the second C-type cylinder 37 to move slowly, and then the silicone waste will move into the feeding cylinder 3. Since the first leakage hole group 31 is located in the opening of the first C-type cylinder 33 in the initial state, when the silicone waste enters the feeding cylinder 3, the silicone waste greater than the first leakage hole group 31 will be moved to the feeding cylinder 3. The silicone waste with the size of the leak hole of the first leak hole group 31 will continue to move in the feed cylinder 3, and the silicone waste with a size smaller than the leak hole of the first leak hole group 31 will fall from the leak hole of the first leak hole group 31, and the fallen silicone waste will fall into the collection bin 43 for collection, and then the silicone waste with a size larger than the leak hole of the first leak hole group 31 will continue to move in the feed cylinder 3 until it moves into the screen cylinder 2. In this process, the large silicone waste can be screened out first, and then the large silicone waste can be introduced into the screen cylinder 2 for separate crushing;

[0073] More specifically, when the large silica gel waste is crushed, the fourth motor 42 is controlled to rotate, and the fourth motor 42 drives the gear 41 to rotate. Since the gear 41 is meshed with the tooth groove 4, it drives the feed barrel 3 to rotate. During the rotation of the feed barrel 3, the first leakage hole group 31 will follow the feed barrel 3 and gradually turn into the first C-type barrel 33. At the same time, the second leakage hole group 32 will gradually emerge from the first C-type barrel 33. At the same time, the feed barrel 3 will rotate along the second C-type barrel 37. When the feed barrel 3 rotates 120 degrees, the second leakage hole group 32 is located at the opening of the first C-type barrel 33. Then, the feed cylinder 3 is controlled to stop rotating, and then the collected silica gel waste in the collecting bin 43 is introduced into the bin 35, and then the auger 39 drives the part of the silica gel waste to move. When the silica gel waste moves into the feed cylinder 3, the silica gel larger than the leakage hole size of the second leakage hole group 32 will continue to move in the feed cylinder 3, and the silica gel waste smaller than the leakage hole size of the second leakage hole group 32 will fall from the leakage hole of the second leakage hole group 32 and fall into the collecting bin 43. In this process, the medium silica gel waste can be screened out, and then the medium silica gel waste can be introduced into the screen cylinder 2 for separate crushing;

[0074] Further, after the medium-sized silica gel waste is crushed, the gear 41 and the tooth groove 4 are used to control the feed cylinder 3 to rotate 120 degrees. After the feed cylinder 3 rotates 120 degrees, the portion located between the first leakage hole group 31 and the second leakage hole group 32 rotates to the opening of the first C-shaped cylinder 33, and then the silica gel waste in the collection bin 43 is introduced into the bin 35. Then, the auger 39 will introduce this part of the silica gel waste into the screen cylinder 2 through the feed cylinder 3 for separate crushing.

[0075] By opening two leak hole groups with different leak hole sizes on the feed barrel 3, silicone waste of different sizes can be screened and divided into large silicone waste, medium silicone waste and small silicone waste, and the screened silicone waste is crushed in batches to avoid crushing silicone waste of different sizes together, which may easily lead to different crushing degrees of waste of different sizes during the crushing process, large silicone waste will be unevenly crushed, and small silicone waste will be over-crushed.

[0076] Embodiment three:

[0077] The side wall of the recovery bin 1 is provided with evenly arranged electric push rods 5, and the electric push rods 5 are installed on the same side as the first motor 12;

[0078] The electric push rod 5 extends to the inside of the recovery bin 1 and is fixed on the first ring plate 22; the first ring plate 22 is rotatably connected to the screen drum 2; first ring strips 51 are provided on both sides of the first ring plate 22, and the first ring strips 51 are fixedly connected to the inner ring surface of the screen drum 2;

[0079] In this embodiment, second annular strips 52 are provided on both sides of the second annular plate 23, and the second annular strips 52 are fixedly connected to the feed barrel 3;

[0080] In this embodiment, the driving rod 26 is a rectangular rod and slides inside the active roller 25;

[0081] In this embodiment, the insertion rod 27 is made of rubber material;

[0082] Specifically, during the crushing of the silicone waste, the electric push rod 5 is controlled to cyclically extend and retract, thereby pushing the first ring plate 22 to move back and forth. Since the first ring plate 22 is rotatably connected to the screen drum 2, the screen drum 2 will rotate along the first ring plate 22 during its rotation. At the same time, since the first ring plate 22 is provided with first annular strips 51 on both sides, the screen drum 2 will be driven to move back and forth in the recovery bin 1 during the back and forth movement of the first ring plate 22. During the back and forth movement of the screen drum 2, the silicone waste in the screen drum 2 will be driven to move back and forth, so that the silicone waste smaller than the screen hole 21 can be better screened out.

[0083] Since the second annular strips 52 provided on both sides of the second annular plate 23 are fixedly connected to the feed cylinder 3, the second annular plate 23 will be driven to move back and forth during the back and forth movement of the screen cylinder 2. At the same time, the second annular plate 23 drives the feed cylinder 3 to move back and forth through the second annular strips 52. During the back and forth movement of the feed cylinder 3, the feed cylinder 3 will move back and forth along the second C-shaped cylinder 37. During the back and forth movement of the feed cylinder 3, the silicone waste in the feed cylinder 3 will be driven to move back and forth, so that the silicone waste in the feed cylinder 3 can be better screened out from the leakage hole group, thereby improving the screening effect of silicone waste of different sizes;

[0084] When the screen drum 2 moves back and forth, the active roller 25 will be driven to move back and forth through the limit ring 24. Since the driving rod 26 is a rectangular rod, the active roller 25 will move back and forth on the driving rod 26, thereby preventing the insertion rod 27 from detaching from the screen hole 21; since the insertion rod 27 is made of rubber material, the friction between the insertion rod 27 and the screen hole 21 can be reduced, thereby preventing the screen hole 21 from being deformed due to the friction of the insertion rod 27 for a long time.

[0085] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
