Description

Technical Field

[0001] The utility model belongs to the technical field of hydrocyclones, and particularly relates to a peat classification hydrocyclone. Background Art

[0002] A hydrocyclone is a common separation and classification device, which commonly uses the principle of centrifugal sedimentation. When the two-phase mixed liquid to be separated enters the hydrocyclone tangentially from the periphery at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Due to the particle size difference between the coarse particles and the fine particles, the centrifugal force, centripetal buoyancy force, fluid drag force, etc. acting on them are different. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the underflow port of the hydrocyclone, while most of the fine particles are discharged through the overflow pipe, so as to achieve the purpose of separation and classification.

[0003] In the prior art, in order to avoid the blockage caused by the residue entering the hydrocyclone, resulting in the reduction or blockage of the sand sediment flow rate at the sand settling port of the hydrocyclone, an interception screen plate is often arranged at the feed pipe to intercept the coarse materials and sundries in the incoming liquid. The interception screen plate also needs to be cleaned after being used for a period of time. However, the cleaning work of the interception screen plate is mainly to manually use a brush to clean the coarse materials and sundries intercepted on one side of the interception screen plate, without other additional assistance, resulting in a slow cleaning speed of the interception screen plate and a long downtime of the equipment. Summary of the Utility Model

[0004] The utility model aims to provide a peat classification hydrocyclone to solve the problem that when cleaning the interception screen plate of the hydrocyclone in the prior art, it needs to be taken out after the machine is stopped, which affects the normal operation of the hydrocyclone, the downtime of the equipment is long, and the work efficiency is reduced.

[0005] A peat classification hydrocyclone in this solution includes a hydrocyclone and a feed pipe. One end of the feed pipe is communicated with the side wall of the hydrocyclone. Two cleaning grooves are arranged in the middle of the feed pipe. The two cleaning grooves are respectively located on opposite sides of the feed pipe. The feed pipe is communicated with the cleaning grooves. A filter frame is arranged in the cleaning grooves. The filter frame is slidably connected in the cleaning grooves and the feed pipe, and one end is always located in the feed pipe. The filter frame is connected with a driving component for driving its translation. Cleaning doors are hinged on the side walls of the two cleaning grooves on both sides. The cleaning doors are located on the side of the opening of the filter frame.

[0006] Working principle and beneficial effects of this solution: During use, start the driving component to drive the filter box to move horizontally, so that one end of the filter box moves into the cleaning groove on one side. At this time, one end of the filter box still remains in the feed pipe. When the peat slurry passes through the feed pipe, it enters the cyclone for separation only after being filtered by the filter box. If the separation efficiency of the cyclone decreases, resulting in excessive changes in the flow rate of the overflow port, the flow rate of the sand settling port, and the pressure of the feed pipe, the driving component can be started to drive the filter box to move towards the cleaning groove on the other side, so that the filtered part of the previous filter box enters the cleaning groove on the other side. At this time, the cleaning door can be opened to clean the filter box at the original filtered part. When the other end of the filter box is blocked, the above operation can be repeated to move the filter box into the cleaning groove on the opposite side for cleaning;

[0007] This cyclone can clean the filter box at the feed pipe without affecting the normal operation of the cyclone. It can be cleaned while running, without affecting the normal operation of the equipment, avoiding the downtime of the equipment, enhancing the working efficiency of the equipment, and ensuring the safety of maintenance personnel.

[0008] Furthermore, the sizes of the cleaning grooves at both ends of the feed pipe are the same as the size of the feed pipe. The length of the filter box is slightly greater than the length of the feed pipe and one of the cleaning grooves. That is, after one end of the filter box completely enters the cleaning groove, the other end still intercepts the cross-section of the feed pipe. The same-sized cleaning grooves and feed pipes can ensure that the filter box always blocks the cross-section of the feed pipe during translation, preventing the peat slurry water from entering the cyclone without being filtered and ensuring the particle size range of the coal slime.

[0009] Furthermore, a partition is fixedly connected to the middle of the filter box. The partition can separate the filter box located in the feed pipe from the filter box located in the cleaning groove. After the partition is provided, when the cleaning door is opened, the peat slurry water in the feed pipe will not enter the cleaning groove to affect the cleaning of the filter box.

[0010] Furthermore, an auxiliary frame is fixedly connected to the outside of one of the cleaning grooves. One end of the driving component extends out of the outside of the auxiliary frame, and the other end passes through the cleaning groove and is connected to the filter box. The auxiliary frame can stabilize the rotation of the driving component.

[0011] Furthermore, the driving component includes a threaded rod and a handle. One end of the threaded rod is fixedly connected to the outside of the filter box. The other end of the threaded rod extends out of the cleaning groove and the auxiliary frame and is threadedly connected to the cleaning groove and the auxiliary frame. The handle is fixedly connected to the other end of the threaded rod. During use, turning the handle can drive the threaded rod to rotate, thereby controlling the translation of the filter box.

[0012] Further, the driving component includes a threaded rod, a driving wheel, and a driven wheel. One end of the threaded rod is fixedly connected to the outside of the filter frame. The other end of the threaded rod extends out of the cleaning groove and the auxiliary frame and is threadedly connected to the cleaning groove and the threaded frame. The driven wheel is threadedly connected to the threaded rod and is always rotatably connected to the top of the auxiliary frame. The driving wheel and the driven wheel are meshed, and the driving wheel is fixedly connected to a motor that drives it to rotate. During use, the motor is started. The rotation of the motor drives the driving wheel to rotate, so that the driven wheel rotates. Since the threaded rod is threadedly connected to the driven wheel, the driven wheel drives the threaded rod to rotate, driving the filter frame to translate. Using a motor can more easily control the movement of the filter frame, and the motor can also be connected to an external controller. After sensing that the sand sediment in the cyclone becomes smaller, the motor is automatically controlled to drive the filter frame to move to the end that was not previously involved in filtration.

[0017] Embodiment 1:

[0018] Basically as shown in the attached Figure 1As shown: A peat classification cyclone includes a cyclone 2, a sand settling port 1, an overflow port 3, and a feed pipe 11. The sand settling port 1 is located at the bottom of the cyclone 2. The overflow port 3 is communicated with the top end of the cyclone 2. The feed pipe 11 is located on the side wall of the cyclone 2 and is communicated with the cyclone 2. Two cleaning grooves 7 are provided in the middle of the feed pipe 11. The two cleaning grooves 7 are respectively located on the opposite sides of the feed pipe 11, and both of the two cleaning grooves 7 are communicated with the feed pipe 11. The cross-sectional sizes of the two cleaning grooves 7 are the same as the cross-section of the feed pipe 11. A filter frame 9 is slidably connected in the cleaning groove 7. One side of the filter frame 9 is not closed. The size of the filter frame 9 is equal to the sizes of the feed pipe 11 and one cleaning groove 7. The filter frame 9 can always intercept the cross-sections of one of the cleaning grooves 7 and the feed pipe 11. A partition 10 is fixedly connected to the middle of the filter frame 9. The partition 10 is perpendicular to the filter frame 9. After one end of the filter frame 9 completely enters the cleaning groove 7, the partition 10 can separate and seal between the cleaning groove 7 and the feed port. Cleaning doors 8 are hinged to the side walls of the cleaning groove 7. The cleaning doors 8 are located on the side where the filter frame 9 is not closed;

[0019] A driving assembly is provided on one side of the filter frame 9. The driving assembly is provided with a threaded rod 5. One end of the threaded rod 5 is fixedly connected to the filter frame 9. The other end of the threaded rod 5 extends out of the cleaning groove 7 and is threadedly connected to the cleaning groove 7. An auxiliary frame 6 is fixedly connected to the outside of the cleaning groove 7 containing one end of the threaded rod 5. The threaded rod 5 extends out of the auxiliary frame 6 and is threadedly connected to the auxiliary frame 6. A handle 4 is fixedly connected to the top end of the threaded rod 5 extending out of the cleaning groove 7.

[0020] Embodiment 2:

[0021] Basically as shown in the appendix Figure 2 As shown: The difference from Embodiment 1 is that the driving assembly includes a driving wheel 14 and a driven wheel 12. The driven wheel 12 is rotatably connected to the auxiliary frame 6. The driven wheel 12 is threadedly connected to the threaded rod 5. The driving wheel 14 is meshed with the driven wheel 12. The driving wheel 14 is fixedly connected with a motor 13.

[0022] Taking Embodiment 2 as an example, the specific implementation process is as follows: When in use, start the motor 13 to drive the driving wheel 14 to rotate, so that the driven wheel 12 engaged with the driving wheel 14 rotates, thereby driving the threaded rod 5 to rotate, causing the threaded rod 5 to move up and down, and then driving the filter box 9 to move up and down until one end of the filter box 9 completely enters one of the cleaning grooves 7. At this time, the other end of the filter box 9 is located in the feed pipe 11 and completely surrounds the cross-section of the feed pipe 11. The partition plate 10 prevents the peat slurry water in the feed pipe 11 from entering the cleaning groove 7. At this time, the cleaning door 8 can be opened to clean the filter box 9 located in the cleaning groove 7. When it is felt that the sediment amount at the sediment outlet 1 decreases, the motor 13 can be started to reverse, driving the driving wheel 14 and the driven wheel 12 to reverse, causing the threaded rod 5 to reverse, thereby driving the filter box 9 to move into the other cleaning groove 7 until one end of the filter box 9 completely enters the other cleaning groove 7. The partition plate 10 closes the opening of the other cleaning groove 7 and the feed pipe 11, and then the cleaning door 8 can be opened to clean the filter box 9 here.

[0023] The above are only the embodiments of the present invention, and common knowledge such as the specific structures and characteristics known in the solutions is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
