Description

Technical Field

[0001] This invention relates to the field of hydrocyclones, and more specifically, to a hydrocyclone that facilitates stirring and a method of using it. Background Technology

[0002] Hydrocyclones are mainly used for dewatering various mineral slurries. Different structural designs are adopted according to different material characteristics and production / installation environments, offering advantages such as low pressure drop, large throughput, and high dewatering efficiency.

[0003] Hydrocyclones are currently widely used and effective fine particle classification devices, and are widely used in grinding systems. They employ the principle of centrifugal sedimentation to separate coarse and fine powders to achieve the desired grinding effect and meet the required standards.

[0004] When existing medium-density mortar enters the hydrocyclone, the internal pressure of the pipeline causes the mortar to collide with the hydrocyclone, generating centrifugal rotational force, which separates the coarse and fine powders in the mortar. However, due to the different particle sizes of the coarse and fine powders, the coarse and fine powders may separate or settle during pipeline transportation. When entering the hydrocyclone, the two cannot be fully mixed. Some fine powders are not affected by centrifugal force, centripetal buoyancy, or fluid drag and are easily discharged directly from the settling port with the coarse powder. This not only fails to achieve sufficient mixing before separation but also reduces the separation efficiency. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this invention is to provide a hydrocyclone that is easy to stir and a method of using it, which effectively solves the problem of uneven particle size of mortar before centrifugal separation and improves the grading efficiency of mortar.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A hydrocyclone that is easy to stir includes a hydrocyclone body, a feed pipe fixedly connected to the side wall of the hydrocyclone body, an overflow pipe fixedly connected to the top of the inner cavity of the hydrocyclone body, and a guide plate fixedly connected to the inner wall of the hydrocyclone body below the feed pipe.

[0010] The overflow pipe sidewall is rotatably connected to a collar, the collar sidewall is fixedly connected to several baffles, and the top of the collar is provided with a driving mechanism.

[0011] Each of the dial plates is equipped with a self-rotating stirring mechanism on its sidewall.

[0012] Furthermore, the drive mechanism includes a motor, the motor spindle is a hollow shaft, a first gear is fixedly connected to the bottom end of the motor spindle, an annular rack is fixedly connected to the end face of the collar, the first gear meshes with the annular rack, and a quick connector is rotatably connected to the top end of the motor spindle;

[0013] A protective cover is fixedly connected to the top surface of the inner cavity of the hydrocyclone cylinder. The protective cover is annular, and the first gear is located inside the protective cover.

[0014] The end face of the collar is provided with a rapid cleaning mechanism.

[0015] Furthermore, the rapid cleaning mechanism includes several through grooves, all of which are opened on the end face of the collar, and the end face of the deflector is provided with a guide hole, which is connected to the through groove, and a one-way valve is installed in each guide hole.

[0016] The through slots all correspond to the motor spindle.

[0017] Furthermore, the self-rotating stirring mechanism includes a rectangular groove, with a rotating shaft rotatably connected to each side wall of the rectangular groove. The bottom end of the rotating shaft passes through a deflector plate and is fixedly connected to a second gear. Several stirring blades are fixedly connected to the rotating shaft on the inner side wall of the rectangular groove. An arc-shaped rack is fixedly connected to the top surface of the guide plate, and the arc-shaped rack meshes with the second gear.

[0018] The top surface of the guide plate has several leakage holes on both sides of the arc-shaped rack.

[0019] Furthermore, two annular limiting blocks are fixedly connected to the inner wall of the collar, and two annular limiting grooves are opened on the side wall of the overflow pipe. The annular limiting blocks are rotatably connected to the annular limiting grooves.

[0020] Furthermore, a nozzle is fixedly connected to the bottom end of the motor spindle, and the nozzle is located below the first gear.

[0021] Furthermore, the sidewall of the collar is concave, and the angle between the lever and the collar is arc-shaped.

[0022] A method for using a hydrocyclone that facilitates stirring includes the following steps:

[0023] S1: When the mortar enters from the feed pipe, the motor is started. The motor drives the collar to rotate through the first gear. The collar drives the deflector plate to rotate quickly, which quickly guides the mortar to the inner wall of the hydrocyclone cylinder.

[0024] S2: The rotating of the paddle plate drives the second gear to rotate. When the second gear meshes with the arc-shaped rack, it can drive the mixing blade to rotate rapidly, mixing the mortar between the paddle plates.

[0025] S3: When the hydrocyclone cylinder stops, water can be injected into the motor shaft by connecting an external water pipe through a quick connector. When the through groove and the nozzle coincide, the water is injected into the through groove and sprayed out through the guide hole to rinse the hydrocyclone cylinder cavity.

[0026] S4: In addition, the water injection volume can be increased so that the water fills the sealing cover and the water can simultaneously fill the through groove and spray out from the guide hole.

[0027] 3. Beneficial Effects

[0028] Compared with the prior art, the advantages of this invention are:

[0029] (1) This technical solution uses the cooperation between the hydrocyclone cylinder, overflow pipe, collar, deflector and drive mechanism, etc. When the mortar enters the inside of the hydrocyclone cylinder, it can drive the collar and deflector to rotate quickly. On the one hand, it increases the impact force between the mortar and the hydrocyclone cylinder and shortens the time for centrifugal classification. On the other hand, the mortar collides with each other between the collar, deflector and hydrocyclone cylinder, so that powders of different particle sizes are mixed, which is beneficial to the classification efficiency.

[0030] (2) This technical solution uses the cooperation between the guide plate, the deflector plate and the self-rotating stirring mechanism. When the mortar enters between the deflector plates during the rapid rotation of the deflector plate, the stirring blade rotates at the same time, which further enhances the stirring effect on the mortar. At the same time, the centrifugal force generated by the rotation of the stirring blade can promote the formation of centrifugal force between the mortar and the hydrocyclone cylinder.

[0031] (3) This technical solution uses the cooperation between the collar, the deflector and the quick cleaning mechanism to inject water into multiple deflectors when the equipment is stopped, so as to wash away the mortar adhering inside the hydrocyclone cylinder, prevent the mortar from sticking together and affecting the smoothness of the inner wall of the hydrocyclone cylinder, and extend the service life of the inner wall material of the hydrocyclone cylinder.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] Example 1:

[0043] Please see Figure 1-7 A hydrocyclone that is easy to stir includes a hydrocyclone body 1, a feed pipe 2 fixedly connected to the side wall of the hydrocyclone body 1, an overflow pipe 3 fixedly connected to the top of the inner cavity of the hydrocyclone body 1, and a guide plate 4 fixedly connected to the inner wall of the hydrocyclone body 1 below the feed pipe 2.

[0044] A collar 5 is rotatably connected to the side wall of the overflow pipe 3. Two annular limiting blocks 21 are fixedly connected to the inner wall of the collar 5. Two annular limiting grooves 22 are opened on the side wall of the overflow pipe 3. The annular limiting blocks 21 and the annular limiting grooves 22 are rotatably connected, which can not only play a role in sealing and limiting, but also support the collar 5 and the lever plate 6. Several lever plates 6 are fixedly connected to the side wall of the collar 5. A driving mechanism is set at the top of the collar 5. The side wall of the collar 5 is concave. The included angle between the lever plate 6 and the collar 5 is arc-shaped. When the mortar enters between the lever plates 6, the mortar rotates with the lever plate 6 and collects between the lever plates 6. When the lever plate 6 rotates 180° from the direction of the feed pipe 2, it throws the mortar out. The arc-shaped included angle can facilitate the mortar to leave the lever plate 6, reduce mortar residue, and at the same time, it does not affect the discharge of fine powder from the overflow pipe 3. A self-rotating stirring mechanism is set on the side wall of the lever plate 6.

[0045] See Figure 2 and Figure 7The drive mechanism includes a motor 8, whose main shaft is a hollow shaft. A first gear 10 is fixedly connected to the bottom end of the motor 8 main shaft, and a ring rack 7 is fixedly connected to the end face of the collar 5. The first gear 10 meshes with the ring rack 7. A quick connector 11 is rotatably connected to the top end of the motor 8 main shaft. The quick connector 11 can be connected to an external water pipe to inject water into the motor 8 main shaft. The water is discharged from the guide hole 13 by the impact force of the water flow, rinsing the inner wall of the hydrocyclone cylinder 1. If the mortar remaining inside the hydrocyclone cylinder 1 is dry... After the slag has solidified, a large amount of mortar needs to be injected during the next operation to flush away the solidified mortar and allow it to fall out of the hydrocyclone cylinder 1. However, this method will cause a large amount of mortar to fail to generate centrifugal force inside the hydrocyclone cylinder 1 in the initial state, thus failing to achieve the grading effect. Therefore, cleaning and maintenance of the hydrocyclone cylinder 1 is essential. A nozzle 9 is fixedly connected to the bottom of the motor 8 spindle. The nozzle 9 is located below the first gear 10. The nozzle 9 can inject water into the through groove 12, so that the water is sprayed out from the guide hole 13.

[0046] Through the cooperation between the hydrocyclone cylinder 1, overflow pipe 3, collar 5, deflector 6 and drive mechanism, when the slurry enters the hydrocyclone cylinder 1, it can drive the collar 5 and deflector 6 to rotate rapidly. On the one hand, this increases the impact force between the slurry and the hydrocyclone cylinder 1, shortening the time for centrifugal classification. On the other hand, the slurry collides with each other between the collar 5, deflector 6 and hydrocyclone cylinder 1, causing powders of different particle sizes to mix, which is beneficial to the classification efficiency.

[0047] A protective cover is fixedly connected to the top surface of the inner cavity of the hydrocyclone body 1. The protective cover is annular, and the first gear 10 is located inside the protective cover.

[0048] A rapid cleaning mechanism is provided on the end face of the collar 5.

[0049] See Figure 3 and Figure 6 The rapid cleaning mechanism includes several through slots 12, all of which are opened on the end face of the collar 5. Each end face of the deflector plate 6 is provided with a guide hole 13, which is connected to the through slot 12. A one-way valve 14 is installed in each of the guide holes 13. The through slots 12 correspond to the main shaft of the motor 8. Through the cooperation between the collar 5, the deflector plate 6 and the rapid cleaning mechanism, when the equipment is stopped, water can be injected into multiple deflector plates 6 to wash away the mortar adhering inside the hydrocyclone cylinder 1, preventing the mortar from sticking together and affecting the smoothness of the inner wall of the hydrocyclone cylinder 1. At the same time, it can extend the service life of the inner wall material of the hydrocyclone cylinder 1.

[0050] See Figure 5 and Figure 6The self-rotating stirring mechanism includes a rectangular trough 15, with rotating shafts 16 rotatably connected to the side walls of the rectangular trough 15. The bottom end of the rotating shaft 16 passes through the deflector plate 6 and is fixedly connected to a second gear 17. Several stirring blades 18 are fixedly connected to the inner side wall of the rotating shaft 16. An arc-shaped rack 19 is fixedly connected to the top surface of the guide plate 4. The arc-shaped rack 19 meshes with the second gear 17. Through the mutual cooperation between the guide plate 4, the deflector plate 6, and the self-rotating stirring mechanism, when the deflector plate 6 rotates rapidly, the stirring blades 18 rotate simultaneously when the mortar enters between the deflector plates 6, further enhancing the stirring effect on the mortar. At the same time, the centrifugal force generated by the rotation of the stirring blades 18 can promote the formation of centrifugal force between the mortar and the hydrocyclone cylinder 1.

[0051] See Figure 5 The top surface of the guide plate 4 is provided with several drainage holes 20 on both sides of the arc-shaped rack 19. The drainage holes 20 can be used to facilitate the discharge of the leaking mortar. The mortar can be discharged with the water flow, avoiding the accumulation of mortar on the guide plate 4, which would affect the transmission efficiency of the second gear 17 and the arc-shaped rack 19.

[0052] Example 2:

[0053] Based on the rapid cleaning mechanism in Example 1, it has an additional operating mode:

[0054] When the density of the mortar injected into the hydrocyclone cylinder 1 through the feed pipe 2 is high, water can be injected into the main shaft of the motor 8 through the external water pipe. The water is sprayed out from the guide hole 13 through the through groove 12 to mix the incoming mortar, increase the moisture content of the mortar, thereby enhancing the grading efficiency of different particle sizes of the mortar. At the same time, it can also promote the centrifugal force, reduce the friction between the mortar and the hydrocyclone cylinder 1, and extend the service life of the inner wall material of the hydrocyclone cylinder 1.

[0055] Example 3:

[0056] Based on Examples 1-2, the rapid cleaning mechanism provides an additional cleaning method:

[0057] When the quick connector 11 is connected to the external water supply pipe, the water inlet of the external water pipe can be controlled, and the water volume can be increased to fill the inside of the sealing cover, so that the water flow can enter multiple through slots 12 at the same time and spray out from the guide hole 13 at the same time to rinse the inside of the hydrocyclone cylinder 1. Some of the water flow gathers on the guide plate 4 and can fall through the leakage hole 20 on the guide plate 4, which can also achieve the rinsing effect.

[0058] When in use: When the mortar enters from the feed pipe 2, the motor 8 is started. The motor 8 drives the ring rack 7 to rotate through the first gear 10. The ring rack 7 drives the collar 5 to rotate. The collar 5 drives the deflector plate 6 to rotate rapidly. When the mortar enters between the deflector plates 6, the mortar is quickly guided to the inner wall of the hydrocyclone cylinder 1 as the deflector plates 6 rotate, which further promotes the kinetic energy of the mortar and shortens the time for the mortar to form centrifugal force on the hydrocyclone cylinder 1.

[0059] While the agitator plate 6 rotates, it drives the second gear 17 to rotate. When the second gear 17 meshes with the arc-shaped rack 19, it can drive the stirring blade 18 to rotate rapidly, stirring and mixing the mortar between the agitator plates 6, thus avoiding problems such as stratification or sedimentation of the mortar due to particle size factors, which would lead to poor grading effect.

[0060] After the hydrocyclone cylinder 1 stops, water can be injected into the main shaft of the motor 8 by connecting an external water pipe through the quick connector 11. When the through groove 12 coincides with the nozzle 9, the water is injected into the through groove 12 and sprayed out through the guide hole 13 to rinse the cavity of the hydrocyclone cylinder 1. In addition, the water injection volume can be increased so that the water fills the sealing cover and the water can simultaneously fill the through groove 12 and spray out from the guide hole 13.

[0061] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
