Description

Technical Field

[0001] This application relates to the field of asphalt production technology, and in particular to a screening device for particulate materials. Background Technology

[0002] In today's building waterproofing field, modified bitumen waterproofing materials have captured a significant market share due to their excellent waterproofing performance, good durability, and relatively affordable cost, and are widely used in various waterproofing projects such as roofs, basements, and bridges. However, the quality of these materials largely depends on the selection and control of raw materials during the production process.

[0003] Traditional material selection methods often rely on manual screening, which is inefficient, difficult to guarantee accuracy, and labor-intensive for workers. For example, manual screening makes it difficult to accurately distinguish between sand and gravel fillers of different particle sizes, easily resulting in the mixing of excessively large or small particles. This leads to an unreasonable gradation of the modified asphalt mixture, which in turn affects the strength, flexibility, and waterproofing effect of the waterproofing material.

Detailed Implementation

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0027] In today's building waterproofing field, modified bitumen waterproofing materials have captured a significant market share due to their excellent waterproofing performance, good durability, and relatively affordable cost, and are widely used in various waterproofing projects such as roofs, basements, and bridges. However, the quality of these materials largely depends on the selection and control of raw materials during the production process.

[0028] Traditional material selection methods often rely on manual screening, which is inefficient, difficult to guarantee accuracy, and labor-intensive for workers. For example, manual screening makes it difficult to accurately distinguish between sand and gravel fillers of different particle sizes, easily resulting in the mixing of excessively large or small particles. This leads to an unreasonable gradation of the modified asphalt mixture, which in turn affects the strength, flexibility, and waterproofing effect of the waterproofing material.

[0029] To address the aforementioned technical problems, this application provides a screening device for granular materials, which can screen asphalt particles to improve the uniformity of particle size and thus improve the processing quality of subsequent granular materials.

[0030] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1 to 7 A detailed description of the screening device for granular materials is provided.

[0031] This application provides a granular material screening device, which includes: a shell 1 with a receiving space; a feed frame 2 disposed at the top of the shell 1; a receiving component 3 disposed at the bottom of the shell 1; a multi-stage filter component 4 located inside the shell 1 and slidably connected to the side wall of the shell 1; a stirring assembly 5, including a stirring component 51 and a power component 52, the power component 52 being disposed in the shell 1, one end of the stirring component 51 penetrating through the feed frame 2, and the other end of the stirring component 51 being connected to the power component 52; and a rotating pressing component 6 disposed inside the shell 1 and connected to the power component 52, wherein during rotation, at least a portion of the component presses against the multi-stage filter component 4 with each rotation.

[0032] Specifically, the granular material screening device includes a shell 1, a feed frame 2, a receiving component 3, a multi-stage filtration component 4, a stirring assembly 5, and a rotating pressing component 6. The feed frame 2 is located at the top of the shell 1, the receiving component 3 is located at the bottom of the shell 1, the multi-stage filtration component 4 is located inside the shell 1 and is slidably connected to the side wall of the shell 1, and the stirring assembly 5 includes a stirring component 51 and a power component 52. The power component 52 is located in the shell 1, one end of the stirring component 51 passes through the feed frame 2, and the other end of the stirring component 51 is connected to the power component 52. The power component 52 drives the stirring component 51 to rotate. The stirring component 51 is located at the port of the feed frame 2. After stirring and fully dispersing the granular material, it falls into the multi-stage filter element 4 inside the shell 1 for screening. Some particles are retained in the multi-stage filter element 4, while some granular material passes through the multi-stage filter element 4 and falls into the receiving element 3, thereby achieving the grading and screening of material particles. The rotating pressing element 6 is set inside the shell 1 and is connected to the power element 52. The power element 52 presses the rotating pressing element 6. During the rotation process, at least some parts of the rotating pressing element 6 press against the multi-stage filter element 4 with each rotation. This repeated action causes the multi-stage filter element 4 to vibrate up and down repeatedly, thereby accelerating the screening efficiency.

[0033] In some optional embodiments, the power unit 52 includes a dual-shaft motor 521, a conveyor belt 522, a drive wheel 523, and a driven wheel 524. The first output shaft of the dual-shaft motor 521 extends into the housing 1, and the second output shaft of the dual-shaft motor 521 is located outside the housing 1. The second output shaft is connected to the drive wheel 523, and the driven wheel 524 is connected to the stirring unit 51. The drive wheel 523 and the driven wheel 524 are respectively engaged with the conveyor belt 522.

[0034] Specifically, the housing 1 is also provided with a support plate 53, which is disposed on the outer surface of the housing 1 and is used to fix and support the dual-shaft motor 521. The first output shaft of the dual-shaft motor 521 extends into the housing 1, and the dual-shaft motor 521 drives the second output shaft to rotate. The second output shaft is connected to the conveyor belt 522 through the drive wheel 523, which drives the conveyor belt 522 to rotate. During the rotation of the conveyor belt 522, the stirring component 51 rotates. The stirring component 51 stirs at the port of the feed frame, and after the particulate material is fully dispersed, it falls into the multi-stage filter component 4 inside the housing 1 for screening. Some particles are retained in the multi-stage filter component 4, and some particulate material passes through the filter component and falls into the receiving component 3, thereby realizing the grading and screening of material particles. The first output shaft is used to connect the rotating pressing component 6. The dual-axis motor 521 drives the first output shaft to rotate, thereby driving the rotating pressing component 6 to rotate. During the rotation process, at least part of the rotating pressing component 6 presses against the multi-stage filter component 4 every time it rotates. This repeated action causes the multi-stage filter component 4 to vibrate up and down repeatedly, thereby accelerating the screening efficiency.

[0035] In some optional embodiments, the stirring component 51 includes a stirring shaft 511 and a plurality of stirring elements 512. The stirring shaft 511 is connected to the feed frame 2 via a bearing. The plurality of stirring elements 512 are arranged sequentially along the axial direction of the stirring shaft 511. The stirring shaft 511 is connected to the power component 52.

[0036] Specifically, the stirring shaft 511 passes through the feed frame 2 and is connected to the feed frame 2 via bearings. The stirring shaft 511 is equipped with a driven gear. The second output shaft of the dual-shaft motor 521 is connected to the drive wheel 523. The drive wheel 523 and the driven wheel 524 are respectively geared to the conveyor belt 522. The dual-shaft motor 521 drives the drive wheel 523 to rotate. During the rotation of the drive wheel 523, the conveyor belt 522 is driven to rotate. The conveyor belt 522 drives the driven wheel 524 to rotate. During the rotation of the driven wheel 524, the stirring shaft 511 is driven to rotate. The stirring shaft 511 drives multiple stirring elements 512 to rotate. The multiple stirring elements 512 stir at the port of the feed frame 2. After the particulate material is fully dispersed, it falls into the multi-stage filter component 4 inside the shell 1 for screening. Some particles are retained in the multi-stage filter component 4, and some particulate material passes through the filter component and falls into the receiving component 3, thereby realizing the grading and screening of material particles.

[0037] Furthermore, the stirring element 512 includes a bushing and a stirring rod. The bushing passes through the stirring shaft 511, and the stirring rod is connected to the bushing. The stirring rods of the multiple stirring elements 512 extend in different directions, so that the particulate material is more fully dispersed and falls into the shell 1. The multiple stirring elements 512 are evenly distributed on the stirring shaft 511 in an alternating pattern, so that the material can be continuously and fully dispersed by the alternating pattern.

[0038] In some alternative embodiments, the rotating pressing component 6 includes a bushing 61 and a pressing rod 62, the pressing rod 62 being disposed on the bushing 61, and the bushing 61 being disposed on the first output shaft.

[0039] Specifically, the first output shaft of the dual-axis motor 521 is used to connect the rotating pressing component 6. The dual-axis motor 521 drives the first output shaft to rotate. The bushing 61 is set on the first output shaft, and the pressing rod 62 is set on the bushing 61, thereby driving the rotating pressing component 6 to rotate. During the rotation of the rotating pressing component 6, the first output shaft rotates, driving the pressing rod 62 to rotate. Every time the rotating pressing component 6 rotates, the pressing rod 62 presses against the multi-stage filter component 4 at least once. This repeated action causes the multi-stage filter component 4 to vibrate up and down repeatedly, thereby accelerating the screening efficiency.

[0040] In some optional embodiments, the housing 1 includes a first sliding sidewall 11 and a second sliding sidewall 12, which are arranged face to face, and the multi-stage filter component 4 is connected to the first sliding sidewall 11 and the second sliding sidewall 12 respectively.

[0041] Specifically, the multi-stage filter component 4 is connected to the first sliding sidewall 11 and the second sliding sidewall 12 respectively. During rotation, the rotating pressing component 6 presses against the multi-stage filter component 4 at least partially with each rotation, causing the multi-stage filter component 4 to vibrate repeatedly, thereby accelerating the screening efficiency. The housing 1 includes a top wall 13, a bottom wall 14, and sidewalls, with the two ends of the sidewalls connected to the top wall 13 and the bottom wall 14 respectively. The storage component 3 is a storage drawer. The housing 1 also includes a support leg 15, which is connected to the bottom wall 14.

[0042] In some optional embodiments, the first sliding sidewall 11 includes a first sub-wall 111, a sliding sub-wall 112, a second sub-wall 113, and an elastic member 114. One end of the first sub-wall 111 and the sliding sub-wall 112 are slidably connected, and the other end of the sliding sub-wall 112 is slidably connected to the second sub-wall 113. The elastic member 114 connects the first sub-wall 111 and the sliding sub-wall 112.

[0043] Specifically, the sliding sub-wall 112 is provided with a second limiting groove 1121 that is recessed from the inner surface to the outer surface, and a protrusion 1111 is provided at the position corresponding to the second limiting groove 1121 of the first sub-wall 111. The protrusion 1111 is inserted into the second limiting groove 1121, and the elastic member 114 is connected to the bottom of the protrusion 1111 and the second limiting groove 1121 respectively.

[0044] Furthermore, one end of the multi-stage filter component 4 is connected to the elastic component 114, and the other end of the multi-stage filter component 4 is connected to the second sliding sidewall 12. A rotating pressing component 6 is disposed inside the housing 1 and is connected to a power component 52. The power component 52 presses the rotating pressing component 6. During rotation, at least a portion of the rotating pressing component 6 presses against the multi-stage filter component 4 with each revolution, thus providing a directional force to the multi-stage filter component 4. As the multi-stage filter component 4 moves, it causes the elastic component 114 to extend and retract. During this extension and retraction, the elastic component 114 causes the sliding sub-wall 112 to move upward. During this movement, the sliding sub-wall 112 slides upward against the first sub-wall 111 and the second sub-wall 113 respectively. When the rotating pressing component 6 no longer contacts the multi-stage filter component 4, the elastic component 114 retracts, causing the sliding sub-wall 112 to move downward. This process repeats, causing the multi-stage filter component 4 to vibrate repeatedly, thereby accelerating the screening efficiency.

[0045] In some alternative embodiments, the elastic component 114 includes a limiting plate 1141, a sliding rod 1142, a slider 1143, and a spring 1144. The sliding rod 1142 connects the first sub-wall 111 and the sliding sub-wall 112. The limiting plate 1141 and the sliding rod 1142 pass through the slider 1143. The sliding rod 1142 passes through the spring 1144, which is located between the slider 1143 and the sliding sub-wall 112.

[0046] Specifically, the slide bar 1142 is connected to the bottom of the protrusion 1111 and the second limiting groove 1121 respectively. The limiting plate 1141 and the slide bar 1142 pass through the slider 1143, so that the slider 1143 can move up and down along the limiting plate 1141 and the slide bar 1142. The limiting plate 1141 is used to close the second limiting groove 1121 to prevent particulate material from moving into the interior of the second limiting groove 1121. The slide bar 1142 is used to guide the slider 1143. One end of the multi-stage filter component 4 is connected to the slider 1143, and the other end is connected to the second sliding sidewall 12. During the rotation of the rotating pressing component 6, at least a portion of its position presses against the multi-stage filter component 4 with each rotation, thereby providing a directional force to the multi-stage filter component 4. During the movement of the multi-stage filter component 4, the elastic component 114 is stretched and contracted. During the extension of the elastic component 114, the slider 1143 is moved upward. During the upward movement of the slider 1143, the spring 1144 is stretched, thereby pulling the sliding sub-wall 112 upward. During the movement of the sliding sub-wall 112, it slides upward with the first sub-wall 111 and the second sub-wall 113 respectively. When the rotating pressing component 6 is no longer in contact with the multi-stage filter component 4, the spring 1144 retracts, thereby driving the sliding sub-wall 112 downward. This process is repeated, which causes the multi-stage filter component 4 to vibrate up and down repeatedly, thereby accelerating the screening efficiency.

[0047] In some optional embodiments, one of the first sub-wall 111 and the sliding sub-wall 112 is provided with a first sliding groove 115, and the other of the first sub-wall 111 and the sliding sub-wall 112 is provided with a first sliding plate 116, the first sliding plate 116 and the first sliding groove 115 being slidably connected; one of the second sub-wall 113 and the sliding sub-wall 112 is provided with a second sliding groove 117, and the other of the second sub-wall 113 and the sliding sub-wall 112 is provided with a second sliding plate 118, the second sliding plate 118 and the second sliding groove 117 being slidably connected; the handle assembly 7 is connected to the first sliding plate 116 and the second sliding plate 118.

[0048] Specifically, the first sub-wall 111 has a first sliding groove 115 at the end facing the sliding sub-wall 112, and the sliding sub-wall 112 has a first sliding plate 116 at the end facing the first sub-wall 111, with the first sliding plate 116 and the first sliding groove 115 slidably connected. The second sub-wall 113 has a second sliding plate 118 at the end facing the sliding sub-wall 112, and the sliding sub-wall 112 has a second sliding groove 117 at the end facing the second sub-wall 113, with the second sliding plate 118 and the second sliding groove 117 slidably connected.

The second sliding plate 118 is slidably connected to the second sliding groove 117.

[0050] In some alternative embodiments, the handle assembly 7 further includes a first handle 71, a connecting rod 72, and a second handle 73. The first handle 71 is connected to the first slide plate 116, the second handle 73 is connected to the second slide plate 118, and the connecting rod 72 is connected to the first handle 71 and the second handle 73 respectively.

[0051] Specifically, the handle assembly 7 is disposed on the outer surface of the housing 1. The first handle 71 is connected to the first slide plate 116, the second handle 73 is connected to the second slide plate 118, and the connecting rod 72 is connected to the first handle 71 and the second handle 73 respectively, thereby limiting the first slide plate 116 and the second slide plate 118 to prevent the first slide plate 116 and the second slide plate 118 from sliding too far due to inertia.

[0052] In some optional embodiments, the multi-stage filtration component 4 includes multiple filter plates 41 arranged sequentially in the height direction of the housing 1. Any two adjacent filter plates 41 are arranged at a preset angle. Any filter plate 41 and one of its adjacent filter plates 41 are connected to the first sliding sidewall 11, and the filter plate 41 and another adjacent filter plate 41 are connected to the second sliding sidewall 12.

[0053] Specifically, in the height direction of the housing 1, the multi-layer filter plates 41 are arranged in the height direction of the housing 1. Optionally, the multi-stage filter component 4 includes three layers of filter plates 41, and the pore size of each layer of filter plates 41 is different. From the top wall 13 to the bottom wall 14 of the housing 1, the pore size of the filter plates 41 becomes smaller and smaller. Among the three layers of filter plates 41, the filter plate 41 located in the middle position is set at a preset angle with the top filter plate 41, and the preset angle ranges from 0 to 90°. The filter plate 41 located in the middle position is set at a preset angle with the bottom filter plate 41, and the preset angle ranges from 0 to 90°. The filter plate 41 located in the middle position and the top filter plate 41 are connected to the slider 1143, and the filter plate 41 located in the middle position and the bottom filter plate 41 are respectively connected to the second sliding side wall 12.

[0054] Each filter plate 41 has a baffle 42 on its side, which is used to collect the particles in each layer.

[0055] In some optional embodiments, the second sliding sidewall 12 includes a first limiting groove 121, a third sliding plate 122 and a third handle 123. The second sliding sidewall 12 surrounds the first limiting groove 121 and a third sliding groove is provided around it. The third sliding plate 122 is slidably connected to the third sliding groove, and the third handle 123 is disposed on the third sliding plate 122.

[0056] Specifically, in the three-layer filter plates 41, the filter plate 41 in the middle position and the filter plate 41 at the top are set at a preset angle, with the preset angle ranging from 0 to 90°.
