Description

Technical Field

[0001] The utility model relates to the technical field of cyclones, in particular to a cyclone group. Background Art

[0002] A cyclone group is usually a system composed of multiple cyclones (or called cyclone separators) for the separation and treatment of liquids or gases. They separate heavier particles or substances through the centrifugal force generated by rotating the fluid and are widely used in the fields of mining, chemical industry, sewage treatment, etc.

[0003] After retrieval, the utility model patent with the publication number of CN211989214U discloses a new type of concentrated classification cyclone group. In this utility model, a stirring shaft with the functions of stirring and accelerating the raw coal mixture is arranged in the central barrel, which can not only ensure the uniformity of the raw coal mixture liquid, but also ensure that the raw coal mixture liquid discharged from the transverse inlet pipe has a large transverse cutting speed. In this way, the materials entering the cyclone can perform centrifugal sedimentation separation along the cyclone, ensuring the separation effect.

[0004] However, raw coal particles are likely to remain on the inner wall of the central barrel of this device. If these particles adhere for a long time, it will affect the uniformity of the fluid and may cause the thickness of the inner wall of the central barrel to increase, resulting in a reduction in its volume. In addition, the cyclone vibrates during operation, and this vibration may cause instability of the entire device, thus significantly affecting its normal operation and working efficiency.

Detailed implementation manners

[0029] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0030] Please refer to Figures 1-10, the utility model provides a hydrocyclone group, which includes a central barrel 1, hydrocyclones 3 and a sand settling box 4. The hydrocyclones 3 are annularly arranged outside the central barrel 1 through a shunt pipe 11. The sand settling box 4 is connected below the central barrel 1. Four groups of support legs 5 are fixedly connected to the lower surface of the sand settling box 4. The lower ends of the support legs 5 are fixedly connected with a base 51. A shock-absorbing base 6 is connected below the base 51. The shock-absorbing base 6 includes a movable ring seat 61 with an open bottom and a fixed ring seat 62 with an open top. The movable ring seat 61 is fixed on the lower surface of the base 51 by bolts. The fixed ring seat 62 is slidably connected to the outside of the movable ring seat 61. A plurality of damping rods 63 and elastic members 64 are connected between the movable ring seat 61 and the fixed ring seat 62. The plurality of damping rods 63 and the plurality of elastic members 64 are cross-distributed. The upper end of the damping rod 63 abuts against the inner top surface of the movable ring seat 61, and the lower end of the damping rod 63 is fixedly connected to the inner bottom surface of the fixed ring seat 62. An upper cover 2 is fixedly connected above the central barrel 1. A through hole 21 is formed on the upper surface of the upper cover 2. An activity cylinder 7 is rotatably connected inside the through hole 21. A stirring shaft 71 is rotatably connected inside the activity cylinder 7. A plurality of fixed rings 72 are fixedly sleeved outside the stirring shaft 71. Four stirring blades 73 are fixedly connected at equal intervals outside the fixed rings 72. The upper end of the stirring shaft 71 and above the upper cover 2 is connected with a speed reduction motor one 74 for driving the stirring shaft 71 to rotate. A fixing frame 22 for fixing the speed reduction motor one 74 is fixedly connected to the upper surface of the upper cover 2. One side of the activity cylinder 7 is connected with a scraping wall assembly 8. The scraping wall assembly 8 includes a connecting plate 81, a scraping wall plate 82 and a scraping bottom plate 83. The connecting plate 81 is fixedly connected to one side of the activity cylinder 7. The scraping wall plate 82 is fixed to the end of the connecting plate 81 away from the activity cylinder 7 by bolts. The scraping wall plate 82 fits on the inner side wall of the central barrel 1. The scraping bottom plate 83 is fixedly connected to the lower end of the scraping wall plate 82. The scraping bottom plate 83 fits on the inner bottom wall of the central barrel 1. One side of the activity cylinder 7 and above the upper cover 2 is connected with a driving member 85 for driving the activity cylinder 7 to rotate.

[0031] By arranging the damping rods 63 and the elastic members 64, the utility model can effectively relieve the vibration that may occur during the operation of the hydrocyclones 3. The damping rods 63 can absorb the vibration, and the elastic members 64 provide additional buffering. By arranging the stirring shaft 71, the speed reduction motor one 74 drives the stirring shaft 71 and the four stirring blades 73 outside to rotate, so as to fully stir the materials in the central barrel 1. By arranging the scraping wall assembly 8, the driving member 85 drives the activity cylinder 7 to rotate. The activity cylinder 7 drives the scraping wall plate 82 and the scraping bottom plate 83 to rotate through the connecting plate 81, so as to scrape the materials attached to the inner wall of the central barrel 1 and deposited at the bottom, making the material mixing more uniform, and at the same time avoiding the problem that the inner wall of the central barrel 1 becomes thicker due to the increase of the inner wall attachments.

[0032] Specifically, the stirring shaft 71 and the wall scraping assembly 8 adopt different drive sources and operate independently. The advantage of this setting is that the wall scraping assembly 8 can adjust the actual rotation speed, rotation times and rotation intervals according to the actual situation to save energy consumption.

[0033] Furthermore, a plurality of connecting seats 611 are annularly and fixedly arranged on the outer side of the movable ring seat 61. Pulley 612 is rotatably connected to both sides of the connecting seat 611. A plurality of T-shaped chutes 621 are opened on both inner sides of the fixed ring seat 62. The pulley 612 is slidably connected inside the T-shaped chute 621 at the corresponding position.

[0034] Specifically, during the operation of the cyclone 3, vibration will be transmitted to the movable ring seat 61. At this time, a relative position change will occur between the movable ring seat 61 and the fixed ring seat 62. The movable ring seat 61 drives the pulley 612 to slide inside the T-shaped chute 621. The T-shaped chute 621 plays a role in limiting the pulley 612, so that the movable ring seat 61 can only move along the path of the T-shaped chute 621, ensuring the stability of the operation of the cyclone 3, preventing the uncontrolled movement of the movable ring seat 61, and thus effectively reducing the impact of vibration on stability.

[0035] Furthermore, a T-shaped limiting block 622 is slidably connected inside the T-shaped chute 621 and above the pulley 612. The upper surface of the T-shaped limiting block 622 is fixedly connected to a square plate 623. The square plate 623 is fixed to the fixed ring seat 62 by bolts.

[0036] Specifically, the T-shaped limiting block 622 plays a role in limiting the pulley 612 to prevent the pulley 612 from sliding out of the T-shaped chute 621. At the same time, it also limits the slidable distance of the pulley 612 and keeps its vibration amplitude within a controllable range. Secondly, when it is necessary to separate the movable ring seat 61 from the fixed ring seat 62, only need to remove the bolts between the square plate 623 and the fixed ring seat 62 and take out the T-shaped limiting block 622 from the T-shaped chute 621, then the movable ring seat 61 can be conveniently taken out from the upper end of the fixed ring seat 62.

[0037] Furthermore, the elastic member 64 includes a bottom plate 641, a sleeve 642 and a sliding rod 643. The bottom plate 641 is fixedly connected to the inner bottom surface of the fixed ring seat 62. The sleeve 642 is fixedly connected to the upper surface of the bottom plate 641. The sliding rod 643 is slidably connected inside the sleeve 642. The upper end of the sliding rod 643 is fixedly connected to a top plate 644. The top plate 644 abuts against the inner top surface of the movable ring seat 61. A spring 645 is fixedly connected between the top plate 644 and the bottom plate 641. The spring 645 is sleeved outside the sleeve 642 and the sliding rod 643.

[0038] Specifically, the vibration generated by the operation of the cyclone 3 is transmitted to the top plate 644 through the movable ring seat 61. The top plate 644 drives the sliding rod 643 to slide inside the sleeve 642. At this time, the spring 645 undergoes elastic deformation, absorbing and weakening the vibration, thereby effectively alleviating the vibration impact.

[0039] Furthermore, an annular base plate 65 is fixedly connected to the outer side of the fixed ring seat 62, and a plurality of fixing grooves 651 are formed through the surface of the annular base plate 65.

[0040] Specifically, the fixed ring seat 62 is placed on the ground through the annular base plate 65. During fixed installation, only need to pass the bolt through the fixing groove 651. The arrangement of the plurality of fixing grooves 651 makes the installation position of the bolt unrestricted.

[0041] Furthermore, a movable seat 84 is fixedly connected to the upper surface of the scraping bottom plate 83, and the movable seat 84 is rotatably sleeved on the outer lower end of the stirring shaft 71.

[0042] Specifically, when the movable cylinder 7 indirectly drives the scraping bottom plate 83 to rotate, it will drive the movable seat 84 to rotate synchronously at the lower end of the stirring shaft 71. The mutual cooperation between the movable seat 84 and the stirring shaft 71 enables the scraping bottom plate 83 to rotate along the axis of the stirring shaft 71 when rotating, thus ensuring that the rotation trajectory of the scraping bottom plate 83 remains under control.

[0043] Furthermore, the driving member 85 includes a first gear 851, the first gear 851 is fixedly sleeved on the outer side of the movable cylinder 7, a second gear 852 is meshed with one side of the first gear 851, and the upper end of the second gear 852 is connected to a second reduction motor 853 through an output shaft. The second reduction motor 853 is fixedly connected inside the fixing frame 22.

[0044] Specifically, the second reduction motor 853 drives the second gear 852 to rotate through the output shaft, and the second gear 852 drives the first gear 851 meshed with it to rotate, thereby indirectly driving the movable cylinder 7 to rotate. Preferably, a timer can be installed at the control end of the second reduction motor 853 to achieve timed operation.

[0045] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
