Description

Technical Field

[0001] This application relates to the field of wheel sand washing machine technology, and in particular to a vibrating dewatering screen device for a wheel sand washing machine. Background Technology

[0002] In today's construction, road building, and various engineering projects, sand is an indispensable basic material, and its performance directly affects the overall quality and durability of the project. However, during the mining, transportation, and storage of sand, it often becomes contaminated with large amounts of impurities, soil, and moisture. Therefore, effective cleaning is crucial to ensure that the sand meets the standards and requirements for engineering applications.

[0003] Existing wheel-type sand washing machines can drive sand and cleaning fluid to tumble in the washing tank through the rotation of the impeller. At the same time, the impeller causes the sand and cleaning fluid to leave the washing tank during the rotation. The impeller is equipped with a sand scooping tank, which is equipped with a filter screen. During the process of the sand and cleaning fluid leaving the washing tank, dehydration is carried out to achieve the purpose of cleaning the sand.

[0004] However, in the existing wheel-type sand washing machine, the cleaning liquid can only flow out of the sand trough through the filter screen during the sand rotation dewatering process, resulting in low sand cleaning efficiency and poor sand cleaning effect. Utility Model Content

[0005] To address the problems in the prior art, this application provides a vibrating dewatering screen device for a wheel-type sand washing machine.

The transmission wheel frame is driven to rotate the elastic wheel frame and the cleaning wheel frame relative to the sand washing container, so as to synchronously rotate into and out of the accommodating space. The outer circumferential surface of the transmission wheel frame is provided with a three-stage tapered guide rail extending along the direction of the rotation axis of the transmission wheel frame; the cleaning wheel frame includes a plurality of first sliders and a plurality of abutting rods, the first sliders are slidably disposed on the three-stage tapered guide rails to allow the cleaning wheel frame to be slidably connected to the transmission wheel frame, the abutting rods are detachably abutting against the discontinuity structure, and are used to push the cleaning wheel frame toward the elastic wheel frame along the direction of the rotation axis of the transmission wheel frame and squeeze the elastic wheel frame; the elastic wheel frame includes a plurality of resetting members that can extend and retract along the direction of the rotation axis of the transmission wheel frame, and are used to push the cleaning wheel frame to reset when the abutting rods are separated from the discontinuity structure.

[0010] Optionally, a flexible waterproof material is provided between the first side panel and the second side panel.

[0011] By adopting the above technical solution, it is beneficial to isolate the reset component from the cleaning fluid, thereby reducing the probability of the reset component rusting during long-term use.

The plurality of abutment rods are located on the side of the cleaning wheel frame away from the elastic wheel frame along the rotation axis of the transmission wheel frame. The end of the abutment rod away from the elastic wheel frame is provided with a ball bearing, which is used to make separable contact with the discontinuity structure.

[0013] By adopting the above technical solution, the sand washing tank is used to carry the sand and washing liquid away from the containment space and allow the sand washing liquid to seep out during the rotation of the washing wheel frame.

[0014] When multiple abutting rods abut against the surface of the discontinuity structure, they are used to push the cleaning wheel frame to squeeze the elastic wheel frame along the direction of the rotation axis of the transmission wheel frame.

[0015] Optionally, the outer circumferential surface of the transmission wheel frame is provided with a single-stage guide rail, which extends in the same direction as the three-stage tapering guide rail and is separated by a second limiting block.

[0016] By adopting the above technical solution, it is beneficial to set the single-stage guide rail and the three-stage tapered guide rail in the same straight direction, which reduces the complexity of the transmission wheel frame and facilitates the later maintenance of the transmission wheel frame.

[0017] Optionally, a first limiting block is provided at the other end of the single-stage guide rail away from the three-stage tapered guide rail; A third limiting block is provided at the other end of the three-stage tapered guide rail away from the single-stage guide rail.

[0024] Optionally, the device further includes a protective component disposed above the rotating mechanism along the direction of gravity, for collecting sand or cleaning fluid thrown out by the cleaning wheel frame during the rotating sand washing process.

[0028] In summary, this application includes the following beneficial technical effects: When using this device for sand washing, the sand to be washed is placed into the receiving space. An elastic wheel frame and a washing wheel frame are mounted side-by-side along the direction of the rotation axis of the outer circumference of the transmission wheel frame. Rotation of the transmission wheel frame drives the elastic wheel frame and the washing wheel frame to rotate synchronously. The first slider of the washing wheel frame is slidably mounted on the three-stage tapered guide rail of the transmission wheel frame. The elastic wheel frame is detachably connected to the transmission wheel frame. The elastic wheel frame and the washing wheel frame abut against each other, and both rotate synchronously into and out of the receiving space under drive. The washing wheel frame includes multiple supporting rods, and multiple sequentially spaced discontinuity structures are provided on the outer shell of the sand washing container. When the supporting rods abut against the discontinuity structures, they can push the washing wheel frame towards the elastic wheel frame along the direction of the rotation axis of the transmission wheel frame and compress the elastic wheel frame. The elastic wheel frame includes multiple resetting members that can extend and retract along the direction of the rotation axis of the transmission wheel frame. When the supporting rods separate from the discontinuity structures, the resetting members push the washing wheel frame to reset. During this process, the washing wheel frame can vibrate to solve the problem that existing wheel sand washing machines cannot vibrate during the sand washing process, resulting in insufficient sand washing efficiency.

[0038] The following is in conjunction with the appendix Figures 1 to 8 This application will be described in further detail below.

[0039] The technical solutions in the embodiments of this application will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this application, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this application without creative effort are also within the protection scope of this application.

[0040] This application discloses a vibrating dewatering screen device for a wheel-type sand washing machine. (Refer to...) Figure 1 The vibrating dewatering screen device of the wheel sand washing machine includes a sand washing container 1 and a rotating mechanism 2.

[0041] The sand washing container 1 has an internal receiving space 10, and a plurality of sequentially spaced discontinuous structures 11 are provided on the outer shell of the sand washing container 1 surrounding the receiving space 10.

[0042] The rotating mechanism 2 includes a transmission wheel frame 21, an elastic wheel frame 22, and a cleaning wheel frame 23. The elastic wheel frame 22 and the cleaning wheel frame 23 are arranged side by side on the outside of the transmission wheel frame 21 along the direction of the rotation axis of the transmission wheel frame 21 and abut against each other. The transmission wheel frame 21 is driven to rotate the elastic wheel frame 22 and the cleaning wheel frame 23 relative to the sand washing container 1, so as to synchronously rotate into and out of the accommodating space 10.

[0043] The outer circumferential surface of the transmission wheel frame 21 is provided with a three-stage tapered guide rail 213 extending along the direction of the rotation axis of the transmission wheel frame 21; the cleaning wheel frame 23 includes a plurality of first sliders 233 and a plurality of abutting rods 232. The first sliders 233 are slidably disposed on the three-stage tapered guide rail 213 so that the cleaning wheel frame 23 is slidably connected to the transmission wheel frame 21. The abutting rods 232 are detachably abutted against the differential structure 11 and are used to push the cleaning wheel frame 23 toward the elastic wheel frame 22 along the direction of the rotation axis of the transmission wheel frame 21 and squeeze the elastic wheel frame 22; the elastic wheel frame 22 includes a plurality of resetting members 225 that can extend and retract along the direction of the rotation axis of the transmission wheel frame 21 and are used to push the cleaning wheel frame 23 to reset when the abutting rods 232 are separated from the differential structure 11.

[0044] The implementation principle of the vibrating dewatering screen device for a wheel-type sand washing machine according to an embodiment of this application is as follows: When using this device for sand washing, the sand to be washed is placed into the receiving space 10. An elastic wheel frame 22 and a washing wheel frame 23 are mounted side-by-side along the direction of the rotation axis on the outer circumference of the transmission wheel frame 21. Rotation of the transmission wheel frame 21 drives the elastic wheel frame 22 and the washing wheel frame 23 to rotate synchronously. A first slider 233 is slidably mounted on the three-stage tapered guide rail 213 of the transmission wheel frame 21. The elastic wheel frame 22 is detachably connected to the transmission wheel frame 21. The elastic wheel frame 22 and the washing wheel frame 23 abut against each other, and both rotate synchronously into and out of the receiving space 10 under drive. The washing wheel frame 23 includes multiple supporting rods 232, and multiple sequentially spaced discontinuous structures 11 are provided on the outer shell of the sand washing container 1. When the holding rod 232 abuts against the break structure 11, it can push the cleaning wheel frame 23 towards the elastic wheel frame 22 along the rotation axis of the transmission wheel frame 21 and compress the elastic wheel frame 22. The elastic wheel frame 22 includes multiple resetting members 225 that can extend and retract along the rotation axis of the transmission wheel frame 21. When the holding rod 232 separates from the break structure 11, the resetting members 225 push the cleaning wheel frame 23 to reset. During this process, the cleaning wheel frame 23 can vibrate to solve the problem of insufficient sand washing efficiency caused by the inability to vibrate during the sand washing process in existing wheel sand washing machines.

[0045] The sand washing container 1 includes a lower receiving structure 12 and an upper receiving structure 13 arranged at intervals, and the receiving space 10 is located in the lower receiving structure 12.

[0046] The lower receiving structure 12 includes a first semi-circular side plate 121, a second semi-circular side plate 122, and an arc plate 123, which enclose the receiving space 10. When the rotating mechanism 2 is located in the receiving space 10, the first semi-circular side plate 121 is located on the side of the cleaning wheel frame 23 away from the elastic wheel frame 22, and the second semi-circular side plate 122 is located on the side of the elastic wheel frame 22 away from the cleaning wheel frame 23. Multiple discontinuity structures 11 are provided on the side of the second semi-circular side plate 122 closest to the receiving space 10. The discontinuity structures 11 are arranged at intervals along the rotation direction of the cleaning wheel frame 23, and the discontinuity structures 11 protrude towards the receiving space 10 relative to the first semi-circular side plate 121.

[0047] The rotating mechanism 2 is located in the accommodating space 10, with the portion of the plane where the center of rotation is located below the direction of gravity. The rotating mechanism 2 indirectly contacts the sand washing container 1 through the accommodating space 10. The rotating mechanism is used to agitate the sand and cleaning fluid in the sand washing container 1.

[0048] The three-stage tapered guide rail 213 includes a primary rail 2131, a secondary rail 2132, and a tertiary rail 2133, which are sequentially arranged and connected along the rotation axis of the transmission wheel frame 21. The width of the tertiary rail 2133 is greater than that of the secondary rail 2132, and the width of the secondary rail 2132 is greater than that of the primary rail 2131. During the track change between the primary rail 2131 and the secondary rail 2132, the first slider 233 will experience physical vibration due to the change in track width. This change in track width provides a clearance and guidance for the cleaning wheel frame 23. During the track change from the secondary rail 2132 to the tertiary rail 2133, the change in track width will cause the cleaning wheel frame 23 to vibrate. An inclined guide surface is provided at the connection between the primary rail 2131 and the secondary rail 2132, and an inclined guide surface is also provided at the connection between the secondary rail 2132 and the tertiary rail 2133. The inclined guide surfaces are used to guide the first slider 233 to reciprocate along the three-stage tapered guide rail 213.

[0049] In some optional embodiments, the vibrating dewatering screen device of the wheel sand washing machine further includes a drive mechanism 3, which is drivenly connected to the rotating mechanism 2 for outputting rotational torque.

[0050] In this embodiment, the drive mechanism 3 includes a motor 31 and a drive rod 32. One end of the drive rod 32 is detachably connected to the motor 31, and the other end is detachably connected to the transmission wheel frame 21. The drive rod 32 is used to provide rotational driving force to the transmission wheel frame 21.

[0051] In some optional embodiments, a single-stage guide rail 211 is provided on the outer peripheral surface of the transmission wheel frame 21. The single-stage guide rail 211 and the three-stage tapered guide rail 213 extend in the same direction and are separated by a second limiting block 212.

[0052] In this embodiment, the outer ring surface of the transmission wheel frame 21 is provided with a three-stage tapered guide rail 213 and a single-stage guide rail 211 extending along the direction of the rotation axis of the transmission wheel frame 21. The three-stage tapered guide rail 213 and the single-stage guide rail 211 are separated by a second limiting block 212. This arrangement is beneficial because the single-stage guide rail 211 and the three-stage tapered guide rail 213 are set in the same straight line direction, reducing the complexity of the transmission wheel frame 21 and facilitating later maintenance of the transmission wheel frame 21.

[0053] In some optional embodiments, a first limiting block 214 is provided at the other end of the single-stage guide rail 211 away from the three-stage tapered guide rail 213; A third limiting block 215 is provided at the other end of the three-stage tapered guide rail 213 away from the single-stage guide rail 211.

[0054] In this embodiment, the first limiting block 214 cooperates with the second limiting block 212 to limit the sliding range of the second slider 224 within the single-stage guide rail 211, preventing it from deviating from the rail. Similarly, the second limiting block 212 cooperates with the third limiting block 215 to limit the sliding range of the first slider 233 within the three-stage tapered guide rail 213, preventing it from deviating from the rail.

[0055] In some optional embodiments, the elastic wheel frame 22 further includes a first side plate 221, a second side plate 222, and a plurality of reset members 225. The first side plate 221 is fixedly connected to the transmission wheel frame 21 by a plurality of locking members 223; The second side plate 222 is slidably connected to the transmission wheel frame 21 via multiple second sliders 224; The reset member 225 is clamped between the first side plate 221 and the second side plate 222 along the direction of the rotation axis of the transmission wheel frame 21, and the second side plate 222 is detachably abutted against the cleaning wheel frame 23.

[0056] In this embodiment, the first side plate 221 is bolted to the outer ring surface of the transmission wheel frame 21 near the drive mechanism 3 to fix the elastic wheel frame 22 and realize the coaxial rotation of the elastic wheel frame 22 and the transmission wheel frame 21.

[0057] The second side plate 222 is connected to the outer ring surface of the transmission wheel frame 21 near the drive mechanism 3 via multiple second sliders 224. The second side plate 222 is located on the side of the first side plate 221 away from the drive mechanism 3. The second side plate 222 is used to allow the elastic wheel frame 22 to slide on the outer ring surface of the transmission wheel frame 21.

[0058] Multiple reset elements 225 employ components with a restoring function, particularly springs. When the elastic wheel carrier 22 is compressed, the multiple reset elements 225 are used to restore the elastic wheel carrier 22 to its uncompressed state.

[0059] In some alternative embodiments, a flexible waterproof material 226 is disposed between the first side plate 221 and the second side plate 222.

[0060] In this embodiment, the flexible waterproof material 226 can be made of materials with waterproof and foldable properties such as fiberglass cloth or rubber cloth. The flexible waterproof material 226 is used to prevent the cleaning fluid from contacting the multiple reset components 225, thereby reducing the probability of the multiple reset components 225 rusting.

[0061] In some optional embodiments, the cleaning wheel frame 23 further includes a plurality of sand washing tanks 231, which are arranged sequentially at intervals on the outer peripheral surface of the cleaning wheel frame 23, and a plurality of through holes 235 are provided on the base plate connecting the plurality of sand washing tanks 231 and the cleaning wheel frame 23.

[0062] Multiple abutment rods 232 are spaced apart along the rotation direction of the cleaning wheel frame 23, and are located on the side of the cleaning wheel frame 23 away from the elastic wheel frame 22 along the rotation axis of the transmission wheel frame 21. A ball bearing 234 is provided at the end of the abutment rod 232 away from the elastic wheel frame 22, and the ball bearing 234 is used to make separable contact with the discontinuity structure 11.

[0063] In this embodiment, the sand washing tank 231 includes two first guard plates 236, two second guard plates 237, and a bottom plate 238. The two first guard plates 236 and two second guard plates 237 are detachably connected to the perimeter of the bottom plate 238, forming a truncated cone with one open end. The sand washing tank 231 is detachably connected to the cleaning wheel frame 23 via the bottom plate 238. The sand washing tank 231 is used to carry sand and cleaning fluid away from the receiving space 10 and allow the sand washing fluid to permeate during the rotation of the cleaning wheel frame 23.

[0064] The lengths of the multiple abutment rods 232 are set according to the distance between the sand washing tank 231 and the sand washing container 1, so that the multiple abutment rods 232 will not abut against the outer shell of the receiving space 10 when they are not rotated to the corresponding position of the differential structure 11; when the multiple abutment rods 232 are rotated to the corresponding position of the differential structure 11, they can abut against and squeeze the differential structure 11. The arc distance between the multiple abutment rods 232 is equal to the arc distance between the multiple differential structures 11, so that the multiple abutment rods 232 and the multiple differential structures 11 abut against or separate synchronously.

[0065] In some alternative embodiments, the discontinuity structure 11 is an arc-shaped protrusion structure used to provide axial displacement for the ball 234.

[0066] In this embodiment, the discontinuity structure 11 is configured as an arc-shaped protrusion, which facilitates the sliding contact between the discontinuity structure 11 and the ball 234. The arc-shaped protrusion can reduce the friction between the discontinuity structure 11 and the ball 234, and the discontinuity structure 11 causes the ball 234 to move in the direction of the rotation axis of the transmission wheel frame 21.

[0067] In some optional embodiments, the vibrating dewatering screen device of the wheel sand washing machine further includes a protective component 4, which is disposed above the rotating mechanism 2 along the direction of gravity and is used to collect the sand or washing liquid thrown out by the washing wheel frame 23 during the rotating sand washing process.

[0068] In this embodiment, the protective component 4 is used to collect the sand or cleaning fluid thrown out by the cleaning wheel frame 23 during rotation and guide the sand or cleaning fluid into the receiving space 10.

[0069] In some alternative embodiments, the device further includes a support mechanism 5, which includes a support frame 51 and a support base 52.

[0070] The support frame 51 is connected to the sand washing container 1 and is used to install the protective component 4.

[0071] The support base 52 is detachably connected to the sand washing container 1 and is used to support the sand washing container 1.

[0072] In this embodiment, the support frame 51 is detachably connected to the arc plate 123, and the support frame 51 is used to install the protective component 4.

[0073] The support base 52 includes a support vertical plate 521 and a support base 522. The support vertical plate 521 is detachably connected to the horizontally placed support base 522 along the direction of gravity.

[0074] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
