Description

Technical Field

[0001] This utility model relates to the field of fluid separation and classification technology, and in particular to a hydrocyclone with adjustable overflow pipe depth. Background Technology

[0002] Hydrocyclones utilize centrifugal force to achieve solid-liquid, liquid-liquid, or solid-solid separation. They offer advantages such as simple structure, large processing capacity, and high separation efficiency, and are widely used in mineral processing, wastewater purification, and oil drilling mud treatment. In actual operation, the overflow pipe, serving as a fine particle discharge channel, plays a decisive role in the separation effect due to its positional parameters. For example, in mineral classification, the overflow pipe depth directly affects the recovery rate of target particle size; in wastewater treatment, its depth relates to the accuracy of suspended solids separation and the clarity of the overflow liquid.

[0003] Currently, most hydrocyclones on the market use a fixed-depth overflow pipe structure, which has significant limitations. Firstly, the fixed depth cannot adapt to different material characteristics, such as particle size, density, concentration, and operating conditions, leading to low separation efficiency. For example, when processing slurries with high fine particle content, an overly shallow overflow pipe can easily cause coarse particles to mix into the overflow product; conversely, when processing coarse-particle materials, an overly deep overflow pipe will cause fine particles to be lost in the underflow. Secondly, traditional hydrocyclones struggle to cope with fluctuations in operating conditions during production, such as changes in feed flow rate and pressure. They cannot dynamically adjust the overflow pipe position to maintain optimal separation, thus affecting product quality stability.

[0004] In addition, the existing few adjustable overflow pipe structures have problems such as low adjustment accuracy, complicated operation and poor sealing performance, resulting in poor practical application effect. Therefore, a hydrocyclone with adjustable overflow pipe depth is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a hydrocyclone with adjustable overflow pipe depth to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0006] The technical solution of this utility model embodiment is implemented as follows: A hydrocyclone with adjustable overflow pipe depth includes a hydrocyclone body and a second pipe installed on one side of the hydrocyclone body, and further includes:

[0009] in:

[0010] The second pipe is provided with a fixing groove, and a fixing plate is provided inside the fixing groove.

The bevel gear is meshed with a bevel gear, and a rotating rod is fixedly installed in the middle of the bevel gear.

[0019] I. This utility model achieves flexible adjustment of the overflow pipe insertion depth, enabling it to adapt to different material characteristics, such as particle size, density, and concentration, as well as working conditions, such as changes in feed flow rate and pressure. This solves the problem that a fixed-depth overflow pipe cannot handle multiple separation scenarios, improving the equipment's adaptability to complex working conditions.

[0031] Some technical issues, main solutions, minor technical issues and their solutions

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 1-4 As shown, this utility model embodiment provides a hydrocyclone with adjustable overflow pipe depth, including a hydrocyclone body 1 and a pipe 7 installed on one side of the hydrocyclone body 1, and further including:

[0034] Rotating assembly 14 is installed on pipe 2 7;

[0035] The movable component 15 is mounted on the rotating component 14;

[0036] in:

[0037] The pipe 2 7 is provided with a fixing groove 12, and a fixing plate 13 is provided inside the fixing groove 12. The rotating component 14 includes a knob 141. A rotating rod 142 is provided on one side of the knob 141. A bevel gear 143 is fixedly installed on the outside of the rotating rod 142. A bevel gear 144 is meshed with the bevel gear 143. A rotating rod 145 is fixedly installed in the middle of the bevel gear 144.

[0038] In this embodiment, the rotating assembly 14 drives the rotating rod 145 to rotate, which in turn drives the lead screw 151 to rotate. Since the lead screw 151 is threadedly engaged with the slider 152, the slider 152 moves along the axial direction of the lead screw 151, which drives the overflow pipe 9 to move synchronously. The overflow pipe 9 slides with the slider 153 and the sliding rod 154 to ensure stable movement direction.

[0039] Specifically, the moving component 15 includes a lead screw 151, one side of a rotating rod 145 is connected to the lead screw 151, a slider 152 is threadedly connected to the outside of the lead screw 151, an overflow pipe 9 is installed on the side of the slider 152 away from the lead screw 151, a slider 153 is connected to the side of the overflow pipe 152 away from the slider 152, a sliding rod 154 is slidably connected to the side of the slider 153 away from the overflow pipe 9, and a groove 3 is provided on the pipe 7.

[0040] In a preferred embodiment, the rotating rod 142 is rotated by an external manual knob 141 or an electric drive component. Since the rotating rod 142 passes through and rotates on the fixed plate 13, it can stably transmit torque. The bevel gear 143 on the rotating rod 142 rotates accordingly, meshing and driving the bevel gear 144 and the rotating rod 145 to rotate synchronously, thereby achieving precise lifting and lowering of the overflow pipe.

[0041] Specifically, slider 153 and slider 154 are provided with three sets of sliding grooves, and four sets of pipes are provided in the sliding grooves. Screw 151 and slider 154 are located in the sliding grooves. A folded pipe 8 is installed on one side of overflow pipe 9. Pipe 4 is installed on the side of folded pipe 8 away from overflow pipe 9. The outer side of pipe 4 is installed on pipe 7.

[0042] As a preferred implementation, the folded tube 8 stretches or contracts as the overflow tube 9 moves, adapting to changes in length and enabling adjustment of the overflow tube depth within the pipe 11. The overflow tube depth is precisely controlled by the precision transmission of the lead screw 151 and the slider, and the guide limit of the slide rod 154, meeting the adjustment requirements of the overflow position under different working conditions and improving the adaptability of the device to complex working conditions.

[0043] Specifically, one side of pipe 2 7 is fixedly connected to cylindrical section 2 104. Pipe 3 11 is provided inside cylindrical section 2 104. Overflow pipe 1 9 slides inside pipe 3 11. An O-ring seal 10 is provided at the connection between overflow pipe 1 9 and pipe 3 11.

[0044] As a preferred implementation, when the overflow pipe 9 slides inside the pipe 11, the O-ring 10 continuously fills the gap between them, preventing fluid leakage; the O-ring 10 solves the sealing problem of the dynamic fit between the overflow pipe and the pipe 11.

[0045] Specifically, the hydrocyclone body 1 includes a cylindrical section 101, a conical section 102 is installed on one side of the cylindrical section 101, an underflow port 103 is installed on the side of the conical section 102 away from the cylindrical section 101, and the other side of the cylindrical section 101 is installed on a cylindrical section 2 104.

[0046] In a preferred embodiment, the fluid enters from the feed port 2 of the cylindrical section 2 104. In the main chamber formed by the cylindrical section 101 and the conical section 102, solid-liquid separation is achieved by centrifugal force according to the principle of hydrocyclone. After separation, the underflow is discharged from the underflow port 103.

[0047] Specifically, a limiting groove 6 is provided on pipe 2 7, and a flange seal 5 is provided on the limiting groove 6. Pipe 1 4 and pipe 2 7 are fixed together by the flange seal 5.

[0048] As a preferred implementation, the flange seal 5 is used to secure and seal the connection between pipe 4 and pipe 7 through the flange structure to prevent fluid leakage between the pipes. The flange seal 5 solves the static sealing problem of the pipe connection and together ensures the closed fluid environment inside the device, avoiding leakage from affecting the separation effect, causing resource waste or environmental pollution.

[0049] Specifically, the rotating rod 142 passes through and rotates on the fixed plate 13.

[0050] As a preferred embodiment, the fixed plate 13 limits the rotation of the rotating rod 142, ensuring stable transmission of the rotating assembly 14.

[0051] Specifically, a feed inlet 2 is provided on one side of the cylindrical section 2 104.

[0052] In this embodiment, the present invention operates as follows: When the overflow pipe depth needs to be adjusted, the operator manually rotates knob 141. Knob 141 drives rotating rod 142 to rotate on fixed plate 13. The bevel gear 143 on the outer side of rotating rod 142 rotates accordingly, driving bevel gear 144 and rotating rod 145 to rotate synchronously through meshing transmission. Rotating rod 145 drives the connected lead screw 151 to rotate. Since the lead screw 151 is threadedly engaged with slider 152, slider 152 moves axially along lead screw 151, thereby driving the overflow pipe 9 connected to it to move synchronously. Slider 153 on the other side of overflow pipe 9 moves on slide rod 154. The upward sliding ensures stable movement. Simultaneously, the folded tube 8 stretches or contracts as the overflow tube 9 moves to adapt to length changes. Once the overflow tube 9 is adjusted to the required depth, the fluid enters the cylindrical section 104 from the inlet 2, and then flows into the cylindrical section 101 and conical section 102 of the hydrocyclone body 1. Under centrifugal force, solid-liquid separation is achieved. The underflow after separation is discharged from the underflow port 103, while the overflow is discharged through the overflow tube 9, the folded tube 8, and the pipe 4. During this process, the O-ring seal 10 ensures the sealing at the connection between the overflow tube 9 and the pipe 11, and the flange seal 5 ensures a tight connection between the pipe 4 and the pipe 7 to prevent fluid leakage.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
