Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a sand separation device for screening a combination of a screen cylinder and a screen plate. Background Technology

[0002] Sand screening is a common material separation process in the construction and building industries, primarily used to separate impurities or particles of different sizes from sand. This process yields purer sand with more uniform particle size to meet diverse engineering needs.

[0003] Currently, sand screening is generally carried out using a rotating sand screening machine. Sand is fed into the machine, and the machine vibrates, causing the screen discs to vibrate. Smaller sand particles fall through the screen discs, while larger particles or impurities remain above the discs, thus achieving sand screening. However, in some large-scale construction projects, there is a need to rapidly screen large quantities of coarse construction sand while precisely separating fine sand for decorative purposes or special processes. Traditional sand screening machines cannot meet both of these demands. Utility Model Content

[0004] The main purpose of this utility model is to provide a sand separation device that combines a screen cylinder and a screen disc, aiming to solve the problem that traditional sand screening machines cannot meet multiple needs.

[0005] To achieve the above objectives, the technical solution proposed by this utility model is as follows:

The first roller group is at a higher horizontal level than the second roller group, and the first motor drives the first roller group. The first roller group and the second roller group are respectively used to abut against the outer wall of the screen cylinder to make the screen cylinder inclined. The first motor is used to drive the first roller group to rotate, so that the first roller group cooperates with the second roller group to drive the screen cylinder to rotate, so that the screen cylinder completes the initial sieving and sends the initially sieved sand into the screen plate.

[0008] Preferably, the first roller group includes two first rollers, the central axes of the two first rollers are parallel and spaced apart; the second roller group includes two second rollers, the central axes of the two second rollers are parallel and spaced apart, the horizontal height of the two first rollers is higher than that of the two second rollers; the two first rollers and the two second rollers respectively abut against the outer wall surface of the screen cylinder.

The end of the first connecting plate away from the driving structure extends out of the connecting chute and connects to the screen plate. The driving structure drives the first connecting plate to slide back and forth along the connecting chute, so that the first connecting plate drives the screen plate to vibrate back and forth, thereby sieving the sand that was sieved initially through the chute again.

[0012] Preferably, the driving structure includes a first hinge shaft, a second hinge shaft, a second connecting plate, a connecting disc, and a second motor.

[0031] This utility model proposes a sand separation device for screening using a combination of a sieve cylinder and a sieve disc.

[0032] like Figures 1 to 3The sand sieving device shown includes a frame 1, a screen cylinder 11, a screen disk 12, a first driver 2, and a second driver 3. The screen cylinder 11, the screen disk 12, the first driver 2, and the second driver 3 are all mounted on the frame 1. The screen cylinder 11 and the screen disk 12 are arranged vertically. Both ends of the screen cylinder 11 are open. The aperture of the screen cylinder 11 is larger than the aperture of the screen disk 12. The first driver 2 drives and connects to the screen cylinder 11, and the second driver 3 drives and connects to the screen disk 12.

[0033] The sieve cylinder 11 and sieve disc 12 are arranged vertically from top to bottom on the frame 1 so that the sand passes through the sieve cylinder 11 and sieve disc 12 in sequence, thereby achieving the single filtration of sand with multiple particle sizes to meet the needs of construction sand and fine decoration.

[0034] The first drive 2 includes a first roller group, a second roller group, and a first motor 23. The first roller group is at a higher horizontal level than the second roller group, and the first motor 23 drives the first roller group. The first roller group and the second roller group are respectively used to abut against the outer wall of the screen cylinder 11, so that the screen cylinder 11 is set at an inclination. The first motor 23 is used to drive the first roller group to rotate, so that the first roller group cooperates with the second roller group to drive the screen cylinder 11 to rotate, so that the screen cylinder 11 completes the initial sieving and sends the sand from the initial sieving into the screen plate 12. The first roller group abuts against the end of the screen cylinder 11 at a higher horizontal level, and the second roller group abuts against the end of the screen cylinder 11 at a lower horizontal level, so that the screen cylinder 11 is set at an inclination, so that the remaining sand after sieving can enter the next process.

[0035] The first roller group includes two first rollers 21, whose central axes are parallel and spaced apart. The second roller group includes two second rollers 22, whose central axes are parallel and spaced apart. The horizontal height of the two first rollers 21 is higher than that of the two second rollers 22. The two first rollers 21 and the two second rollers 22 respectively abut against the outer wall surface of the screen cylinder 11. The two first rollers 21 and the two second rollers 22 are sandwiched against the outer wall surface of the screen cylinder 11 in pairs, so that the screen cylinder 11 can be rotated when the two first rollers 21 and the two second rollers 22 rotate.

[0036] Specifically, one of the first rollers 21 and one of the second rollers 22 are coaxially arranged in the top view direction, and the other first roller 21 and the other second roller 22 are coaxially arranged in the top view direction.

[0037] The first driver 2 includes a connecting wheel 25 and a belt 26. The connecting wheel 25 and one of the first rollers 21 are fixedly connected by a connecting shaft, and the connecting wheel 25 and the connected first roller 21 are coaxially arranged. The belt 26 is respectively sleeved on the connecting wheel 25 and the output end of the first motor 23. The first motor 23 is used to drive the connecting wheel 25 to rotate through the belt 26, so that the connecting wheel 25 drives the first roller 21 to rotate through the connecting shaft. The first motor 23 drives the connected first roller 21 in sequence through the belt 26 and the connecting wheel 25, so that the connected first roller 21 drives the screen cylinder 11 to rotate. Then, in conjunction with the remaining first roller 21 and the two second rollers 22, the screen cylinder 11 rotates and passes through the screen.

[0038] The frame 1 is also equipped with two support frames 24, one of which is located between the two first rollers 21, and the other is located between the two second rollers 22. The screen cylinder 11 is located between the two support frames 24. The two support frames 24 have limiting grooves (not shown in the figure) on the side facing the screen cylinder 11. One end of the screen cylinder 11 is slidably inserted into the limiting groove of one support frame 24, and the other end of the screen cylinder 11 is slidably inserted into the limiting groove of the other support frame 24. The two support frames 24 clamp and limit the screen cylinder 11 through the two limiting grooves, fixing the screen cylinder 11 to the top side of the frame 1; at the same time, the two limiting grooves ensure that the screen cylinder 11 can rotate normally after being relatively fixed.

[0039] Specifically, the horizontal height of the support frame 24 located between the two first rollers 21 is higher than the horizontal height of the support frame 24 located between the two second rollers 22.

[0040] The second drive 3 includes a connecting chute 31, a first connecting plate 32, and a drive structure. The connecting chute 31 is arranged horizontally, with the screen 12 located at one end of the connecting chute 31 and the drive structure located at the other end of the connecting chute 31. The first connecting plate 32 is located inside the connecting chute 31, and the drive structure drives the first connecting plate 32. The end of the first connecting plate 32 away from the drive structure extends out of the connecting chute 31 and connects to the screen 12. The drive structure is used to drive the first connecting plate 32 to slide back and forth along the connecting chute 31, so that the first connecting plate 32 drives the screen 12 to vibrate back and forth, and sieves the sand that has been sieved the first time.

[0041] The driving structure includes a first hinge shaft 33, a second hinge shaft 34, a second connecting plate 35, a connecting disc 36, and a second motor 37. The connecting disc 36 is located at the end of the connecting groove 31 away from the screen plate 12. Both the first hinge shaft 33 and the second hinge shaft 34 are arranged vertically. One end of the second connecting plate 35 is rotatably connected to the first connecting plate 32 through the first hinge shaft 33, and the other end of the second connecting plate 35 is rotatably connected to the connecting disc 36 through the second hinge shaft 34. The second motor 37 is located on the side of the connecting disc 36 away from the second hinge shaft 34. The output end of the second motor 37 drives the connecting disc 36. The second motor 37 is used to drive the connecting disc 36 to rotate, so that the connecting disc 36 passes through the second hinge shaft 34, the second connecting plate 35, and the first hinge shaft 33 in sequence, driving the first connecting plate 32 to slide repeatedly along the connecting groove 31. The cooperation of the second connecting plate 35, the first hinge shaft 33 and the second hinge shaft 34 converts the mechanical energy of the connecting plate 36 in the rotation direction into the reciprocating mechanical energy of the first connecting plate 32, so as to realize the lateral vibration of the screen plate 12.

[0042] The frame 1 has two slide rails 13, located at the end of the connecting groove 31 away from the second motor 37. The two slide rails 13 are arranged parallel to each other and are parallel to the first connecting plate 32. Each slide rail 13 has at least one slide block 14, and the screen plate 12 is located between the two slide rails 13. Each slide block 14 is connected to the screen plate 12. The cooperation between the slide rails 13 and the slide blocks 14 further improves the stability of the screen plate 12 during sieving.

[0043] Specifically, one slide rail 13 is equipped with two slide blocks 14, and the other slide rail 13 is also equipped with two slide blocks 14.

[0044] The bottom of the frame 1 is equipped with casters 15. The casters 15 facilitate the overall movement of the frame 1.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
