Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crushing equipment, and particularly relates to a preparation device for rubber asphalt. BACKGROUND

[0002] The rubber asphalt is formed by processing waste tires into rubber powder particles, combining according to a certain coarse-fine gradation ratio, adding various high polymer modifiers, and fully mixing and reacting with base asphalt at a certain high temperature. At present, the rubber asphalt needs to be taken out from the inside of the reaction kettle after preparation, but the molten rubber asphalt has certain viscosity and is easy to block the discharge port on the side wall of the reaction kettle, which is not convenient for workers to take out the rubber asphalt.

[0003] To solve the above problems, a rubber asphalt preparation device is disclosed in Chinese Patent No. CN116870852A, which comprises a base, a cover and a reaction kettle. The base is provided with oppositely distributed supports, the reaction kettle is rotationally connected with the supports and is connected with a rotating mechanism, the rotating mechanism is used to drive the rotation of the reaction kettle, the cover is connected with the base through oppositely distributed extension rods, and a crushing mechanism is arranged on the cover and used to crush the rubber asphalt. A heating mechanism is arranged at the bottom of the reaction kettle. The device melts the rubber asphalt through the heating mechanism at the bottom of the reaction kettle, and during the preparation of the rubber asphalt, the cover is closed, and then the rubber asphalt is crushed by the crushing mechanism, so that the rubber asphalt can be fully melted. When the rubber asphalt is prepared, the cover is driven upward by the extension rods, the rotating mechanism drives the rotation of the reaction kettle, and then the reaction kettle is inclined. At this time, the rubber asphalt can flow out from the inside of the reaction kettle, which is convenient for workers to take out the rubber asphalt in the reaction kettle.

[0004] The above device has the following problems in actual use: When the device is used, the feeding of the rubber asphalt is mainly performed by workers. Therefore, if the workers place a large amount of rubber asphalt at a time during the feeding of the rubber asphalt into the reaction kettle, the melting effect of the heating mechanism will be weakened, the flow efficiency of the hot gas between the rubber asphalt will be low, and the melting quality of the rubber asphalt will be affected. If the workers place a small amount of rubber asphalt at a time, the melting efficiency will be reduced and the melting time will be prolonged. In addition, if the workers place a certain amount of rubber asphalt into the reaction kettle at a time, the working intensity of the workers will be increased. With the passage of time, the workers will feel tired. On the one hand, the workers cannot control the amount of rubber asphalt, which brings certain troubles to the melting operation of the rubber asphalt. On the other hand, the rubber asphalt will fall and the utilization rate of the rubber asphalt will be reduced. SUMMARY

[0016] The principle and advantages of the present scheme are as follows:

[0017] The rubber asphalt on the screening plate is cut by the cutter; during the cutting of the cutter, the rubber asphalt is cut into a plurality of rubber particles, and is screened by the screening plate; the rubber particles with qualified particle size fall through the screening plate into the bottom of the preparation cylinder for heating and melting; the rubber particles with unqualified particle size are retained on the screening plate, so that they are cut again by the cutter until the particle size of the rubber particles is qualified.

[0018] The feeding disc rotates synchronously with the rotating shaft during the screening of the rubber asphalt, thereby changing the position of the through hole communicated with the screening plate, so that the feeding position of the rubber particles changes constantly. Through the above movement, the rubber particles are uniformly distributed at the bottom of the preparation cylinder, thereby enhancing the melting effect of the heating plate on the rubber asphalt and improving the melting efficiency of the heating plate.

[0019] By changing the position of the through hole communicated with the feeding disc, the rubber particles can be intermittently and quantitatively dropped at the bottom of the preparation cylinder, on the one hand, realizing small-batch and intermittent feeding, thereby ensuring that the heating plate can melt the rubber particles comprehensively and completely during the melting process, on the other hand, since the amount of rubber particles dropped is moderate, the hot gas can efficiently circulate among the rubber particles in the molten state, thereby speeding up the melting speed of the rubber particles, i.e., further enhancing the melting effect of the rubber particles and shortening the melting time.

[0020] The screening plate can be shaken under the vertical reciprocating movement of the auxiliary block. During the shaking of the screening plate, the rubber particles blocked in the screen hole can be made to do vertical reciprocating movement, thereby ensuring that the rubber particles will not be blocked in the screen hole, enhancing the screening effect of the screen hole and improving the screening efficiency of the screen hole. Moreover, during the shaking of the screening plate, the position of the rubber asphalt accumulated on the screening plate can be changed, so that the rubber asphalt is more uniformly and comprehensively distributed on the screening plate, further enhancing the cutting effect of the cutter and improving the cutting efficiency.

[0021] During the vertical reciprocating movement of the auxiliary block, the elastic block can do vertical reciprocating movement relative to the auxiliary block. During the vertical reciprocating movement of the elastic block, the elastic block has a certain force, and the elastic block can extend into the screen hole, thereby the elastic block pushes the rubber particles blocked in the screen hole to do vertical movement and finally falls on the screening plate, thereby realizing cleaning of the rubber particles blocked in the screen hole and ensuring that the rubber particles will not be blocked in the screen hole.

[0022] The auxiliary block is driven by the arc-shaped block to do reciprocating movement along the arc length direction of the arc-shaped guide cylinder, thereby the auxiliary block can preliminarily scatter the rubber particles during the movement of the rubber particles from top to bottom, so that the rubber particles are dispersed and fall within the action range of the crushing cutter, thereby preparing for secondary crushing of the rubber particles, thereby enhancing the action effect of the crushing cutter and improving the crushing efficiency of the crushing cutter.

[0023] After the rubber particles are scattered by the auxiliary block, the crushing cutter performs secondary crushing on the rubber particles, so that the particle size of the rubber particles is reduced again, thereby realizing finishing of the crushing of the rubber particles. Through the above movement, after the particle size of the rubber particles is reduced again, the heating and melting effect of the heating plate on the rubber particles can be further enhanced, and the heating and melting efficiency can be improved.

[0024] The rubber particles are dispersed by the dispersing block after being secondly crushed, the diffusion block reciprocates along the arc length direction of the arc-shaped groove and the vertical reciprocation of the arc-shaped block, so that the diffusion block has stronger force and beating effect, the diffusion block can further diffuse the rubber particles, and the rubber particles are more evenly dispersed in the preparation cylinder, that is, the dispersion effect of the rubber particles is ensured, and the dispersion efficiency of the rubber particles is improved.

[0025] The rubber particles are dispersed by the dispersing block after being secondly crushed, the diffusion block reciprocates along the arc length direction of the arc-shaped groove and the vertical reciprocation of the arc-shaped block, so that the diffusion block has stronger force and beating effect, the diffusion block can further diffuse the rubber particles, and the rubber particles are more evenly dispersed in the preparation cylinder, that is, the dispersion effect of the rubber particles is ensured, and the dispersion efficiency of the rubber particles is improved.

[0026] During the movement of the diffusion block, the stirring shaft moves synchronously. During the circumferential movement of the stirring shaft, the molten rubber particles are continuously stirred, the melting effect of the rubber particles is enhanced, and the melting efficiency of the rubber particles is improved. At the same time, during the movement of the stirring shaft along the arc length direction of the arc-shaped groove and the vertical reciprocation of the stirring shaft, the stirring shaft can draw several grooves in the molten rubber particles. The grooves can increase the contact area of the molten rubber particles and the hot gas, further shorten the melting time of the rubber particles, and improve the melting quality of the rubber particles; and the grooves can also widen the flow range of the hot gas, so that the hot gas can flow efficiently in the molten rubber particles, thereby enhancing the melting effect of the hot gas on the rubber particles and improving the melting efficiency.

[0058] Specific implementation process:

[0059] After the sealing cover is opened, the rubber asphalt is put into the preparation cylinder 1. After the rubber asphalt is placed, the sealing cover is closed, and the motor and the heating plate 2 are started. During the rotation of the motor, the output shaft of the motor drives the rotating shaft 3 to rotate. During the rotation of the rotating shaft 3, the cutter 57 rotates synchronously. During the rotation of the cutter 57, the rubber asphalt is cut into a plurality of rubber particles, and is screened by the screening plate 4, so that the rubber particles with qualified particle size fall through the screening plate 4 and fall into the bottom of the preparation cylinder 1 for heating and melting; the rubber particles with unqualified particle size are retained on the screening plate 4, so that they are cut again by the cutter 57 until the particle size of the rubber particles is qualified.

[0060] During the screening of the rubber asphalt by the screening plate 4, the discharge disc 5 rotates synchronously with the rotating shaft 3, so that the position of the through hole communicated with the screening plate 4 can be changed, thereby changing the discharging position of the rubber particles. Through the above movement, the rubber particles are uniformly distributed in the bottom of the preparation cylinder 1, thereby enhancing the melting effect of the heating plate 2 on the rubber asphalt and improving the melting efficiency of the heating plate 2.

[0061] Meanwhile, during the continuous change of the relative position of the through hole and the discharge disc 5, the rubber particles can be intermittently and quantitatively dropped into the bottom of the preparation cylinder 1. On the one hand, small-batch and intermittent feeding is realized, so that the heating plate 2 can comprehensively and completely melt the rubber particles during the melting of the rubber particles. On the other hand, since the amount of the dropped rubber particles is moderate, the hot gas can efficiently flow among the rubber particles in the molten state, thereby accelerating the melting speed of the rubber particles, i.e. further enhancing the melting effect of the rubber particles and shortening the melting time.

[0062] During the rotation of the discharging disc 5, the fifth gear 43 meshes with the third arc-shaped gear rack 58, thereby driving the linkage shaft 41 to rotate. During the rotation of the linkage shaft 41, the fourth gear 42 rotates synchronously. During the rotation of the fourth gear 42, the fourth gear 42 meshes with the second arc-shaped gear rack 44, thereby driving the arc-shaped guide block 16 to move along the arc length direction of the arc-shaped guide cylinder 15, and the fourth spring is compressed. When the fifth gear 43 no longer meshes with the third arc-shaped gear rack 58, the fourth spring drives the arc-shaped guide block 16 to reset. Therefore, the arc-shaped guide block 16 can reciprocate along the arc length direction of the arc-shaped guide cylinder 15.

[0063] During the movement of the arc-shaped guide block 16, the arc-shaped block 8 moves synchronously. During the movement of the arc-shaped block 8, the rotating shaft 31 moves synchronously. During the movement of the rotating shaft 31, the second gear 33 meshes with the annular gear rack 30, thereby driving the rotating shaft 31 to rotate. During the rotation of the rotating shaft 31, the first cam 32 rotates synchronously.

[0064] During the rotation of the first cam 32, when the protruding part of the first cam 32 abuts against the slide plate 9, the slide plate 9 moves vertically upward, and the second spring 34 is compressed; when the protruding part of the first cam 32 no longer abuts against the slide plate 9, the slide plate 9 resets under the action of the second spring 34, and the slide plate 9 moves vertically downward. Therefore, the slide plate 9 can reciprocate vertically.

[0065] The slide plate 9 reciprocates vertically, and the auxiliary block 10 moves synchronously. Through the vertical reciprocating movement of the auxiliary block 10, the screening plate 4 can be shaken. During the shaking of the screening plate 4, the rubber particles blocked in the screen holes can be made to move vertically and reciprocally, so as to ensure that the rubber particles will not be blocked in the screen holes, enhance the screening effect of the screen holes, and improve the screening efficiency of the screen holes. Moreover, during the shaking of the screening plate 4, the position of the rubber asphalt accumulated on the screening plate 4 can be changed, so that the rubber asphalt is more evenly and comprehensively distributed on the screening plate 4, further enhancing the cutting effect of the cutter 57 and improving the cutting efficiency.

[0066] During the vertical reciprocating movement of the slide plate 9, the auxiliary shaft 35 moves synchronously. During the movement of the auxiliary shaft 35, the auxiliary shaft 35 rotates through the meshing of the third gear 37 and the first gear rack 36. During the rotation of the auxiliary shaft 35, the second cam 38 rotates synchronously. During the rotation of the second cam 38, when the protruding part of the second cam 38 abuts against the side plate 39, the side plate 39 drives the auxiliary plate 13 to move vertically upward, and the third spring is stretched; when the protruding part of the second cam 38 no longer abuts against the side plate 39, the auxiliary plate 13 resets under the action of the third spring. Therefore, the auxiliary plate 13 can reciprocate vertically.

[0067] Through the above movement, that is, during the vertical reciprocating movement of the auxiliary block 10, the elastic block 14 can be vertically reciprocated relative to the auxiliary block 10. During the vertical reciprocating movement of the elastic block 14, the elastic block 14 has a certain force, and the elastic block 14 can extend into the sieve hole, and then the elastic block 14 will push the rubber particles blocked in the sieve hole to move vertically, and finally fall on the screening plate 4, thereby realizing the cleaning of the rubber particles blocked in the sieve hole, and ensuring that the rubber particles will not be blocked in the sieve hole.

[0068] And, by the arc-shaped block 8 driving the auxiliary block 10 to reciprocate along the arc length direction of the arc-shaped guide cylinder 15, the auxiliary block 10 can preliminarily scatter the rubber particles during the movement of the rubber particles from top to bottom, so that the rubber particles are dispersed and fall within the action range of the crushing knife 23, thereby preparing for the secondary crushing of the rubber particles, thereby enhancing the action effect of the crushing knife 23 and improving the crushing efficiency of the crushing knife 23.

[0069] During the movement of the arc-shaped block 8, the first arc-shaped rack 21 moves synchronously. During the movement of the first arc-shaped rack 21, the first arc-shaped rack 21 is engaged with the first gear 20, thereby driving the short shaft 18 to rotate. During the rotation of the short shaft 18, the short shaft 18 drives the crushing shaft 19 to rotate under the action of the belt 22. During the rotation of the crushing shaft 19, the crushing knife 23 rotates synchronously.

[0070] During the rotation of the crushing knife 23, the crushing knife 23 can secondarily crush the rubber particles scattered by the auxiliary block 10, so that the particle size of the rubber particles is reduced again, thereby realizing the finishing of the crushing of the rubber particles. Through the above movement, after the particle size of the rubber particles is reduced again, the heating and melting effect of the heating plate 2 on the rubber particles can be further enhanced, and the efficiency of heating and melting is improved.

[0071] During the vertical reciprocating movement of the sliding plate 9, the sliding plate 9 drives the second rack 46 to move synchronously through the fixed block 45. During the movement of the second rack 46, the second rack 46 is engaged with the sixth gear 48, thereby driving the power shaft 47 to rotate. During the rotation of the power shaft 47, the incomplete bevel gear 49 rotates synchronously. During the rotation of the incomplete bevel gear 49, the incomplete bevel gear 49 is engaged with the first bevel gear 50 and the second bevel gear 51 in turn, thereby enabling the dispersing shaft 24 to swing intermittently. During the movement of the dispersing shaft 24, the dispersing block 25 moves synchronously.

[0072] During the movement of the dispersing block 25, the dispersing block 25 can scatter the secondarily crushed rubber particles, further promoting the distribution of the rubber particles in the preparation cylinder 1, thereby reducing the probability of accumulation of rubber asphalt, improving the storage effect of the preparation cylinder 1, and ensuring that the rubber particles can be evenly distributed in the preparation cylinder 1.

[0073] During the rotation of the first cam 32, when the first cam 32 abuts against the slider 26, the slider 26 moves along the arc length direction of the arc-shaped slot 52, and the fifth spring is compressed; when the protruding part of the first cam 32 no longer abuts against the slider 26, the slider 26 is reset under the action of the fifth spring. Therefore, the slider 26 can reciprocate along the length direction of the arc-shaped slot 52. During the movement of the slider 26, the arc-shaped moving block 59 moves synchronously. During the movement of the arc-shaped moving block 59, the arc-shaped plate 55 moves synchronously.

[0074] During the movement of the arc-shaped plate 55, the third rack 60 can reciprocate vertically through the meshing of the sixth gear 48 and the third rack 60. During the movement of the third rack 60, the third rack 60 can further drive the arc-shaped plate 55 to reciprocate vertically through the mutual cooperation with the sixth spring 56. Therefore, the arc-shaped moving block 59 reciprocates along the arc length direction of the arc-shaped slot 52, and the arc-shaped moving block 59 can also reciprocate vertically. During the movement of the arc-shaped moving block 59, the diffusion block 28 moves synchronously.

[0075] Therefore, after the rubber particles are dispersed by the dispersion block 25, the diffusion block 28 has stronger acting force and beating effect through the reciprocation of the diffusion block 28 along the arc length direction of the arc-shaped slot 52 and the vertical reciprocation of the arc-shaped block 8, so that the diffusion block 28 can further diffuse the rubber particles, promote the more comprehensive and uniform dispersion of the rubber particles in the preparation cylinder 1, ensure the dispersion effect of the rubber particles, and improve the dispersion efficiency of the rubber particles.

[0076] During the movement of the diffusion block 28, the stirring shaft 29 moves synchronously. During the circumferential movement of the stirring shaft 29, the molten rubber particles can be continuously stirred, the melting effect of the rubber particles is enhanced, and the melting efficiency of the rubber particles is improved. Meanwhile, during the movement of the stirring shaft 29 along the arc length direction of the arc-shaped slot 52 and the vertical reciprocation of the stirring shaft 29, the stirring shaft 29 can draw several grooves in the molten rubber particles. The grooves can increase the contact area of the molten rubber particles and the hot gas, further shorten the melting time of the rubber particles, improve the melting quality of the rubber particles, expand the flow range of the hot gas, enable the hot gas to flow efficiently in the molten rubber particles, enhance the melting effect of the hot gas on the rubber particles, and improve the melting efficiency.

[0077] In summary, the efficient crushing of the rubber asphalt, the control of the number of rubber particles, and the uniform distribution of the rubber particles at the bottom of the preparation cylinder 1 are realized, so that the heating plate 2 can more comprehensively and completely melt the rubber asphalt during the melting of the rubber asphalt.

[0078] After the rubber asphalt is prepared, the rubber asphalt can be taken out along the conduit 7 to prepare for further processing of the rubber asphalt.
