Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge cyclone technology, specifically to a heavy sludge cyclone separation system. Background Technology
[0002] Hydrocyclones, as a commonly used classifying and thickening device, are characterized by large processing capacity, high classification efficiency, small footprint, low operating costs, and flexible installation. They are widely used in mining, metallurgy, petroleum, and chemical industries. The unique form of slurry movement generates high tangential velocity, large velocity gradient, and strong turbulence in the radial direction, creating a centrifugal force field tens, hundreds, or even thousands of times larger than gravity, enormous shear stress, and intense mixing. This allows them to perform multiple separation functions, including classification, separation, concentration, clarification, washing, and mass transfer, and they are widely used in many technological fields of the national economy. Looking at the current development trend, for any two-phase slurry separation project involving differences in particle size, density, and shape, hydrocyclones are undoubtedly one of the preferred equipment options.
[0003] However, existing hydrocyclone separators do not effectively disperse heavy sludge during the treatment of heavy sludge, resulting in poor hydrocyclone separation performance. Utility Model Content
[0004] The purpose of this invention is to provide a heavy sludge cyclone separation system to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A heavy sludge hydrocyclone separation system includes a hydrocyclone and a pretreatment component. An inlet pipe is installed on the left side of the upper end of the hydrocyclone. A cyclone rod is installed inside the hydrocyclone. A drive motor is installed in the middle of the upper part of the hydrocyclone. The drive end of the drive motor passes through the hydrocyclone and is connected to the cyclone rod. A coarse material discharge pipe is provided at the lower end of the hydrocyclone. An overflow pipe is installed on the right side of the hydrocyclone.
[0007] The pretreatment assembly includes a barrel cover and a connecting frame. The connecting frame is installed below the barrel cover, and its lower end is connected to the inner cavity of the liquid inlet pipe. A rotating motor is fixedly installed inside the barrel cover, and the drive shaft of the rotating motor is connected to the upper grinding disc. A feeding pipe is installed in the middle of the upper grinding disc. A lower grinding disc is installed inside the connecting frame. The upper grinding disc and the lower grinding disc are directly opposite each other. Liquid inlet holes are provided on the surfaces of the lower grinding disc and the connecting frame.
[0008] Preferably, a reinforcing frame is installed at the lower end of the liquid inlet pipe, and the reinforcing frame is connected to the side wall of the hydrocyclone.
[0009] Preferably, a filter cover is installed on the inner cavity side surface of the hydrocyclone, and the end of the overflow pipe is located inside the filter cover.
[0010] Preferably, the filter cover is mounted on the inner wall of the hydrocyclone via a connecting plate, a waterproof electric push rod is mounted on the connecting plate, a cleaning brush ring is movably sleeved on the outer surface of the filter cover, an installation ring is provided on the outer surface of the cleaning brush ring, and the telescopic end of the waterproof electric push rod is connected to the installation ring.

[0012] This invention provides a heavy sludge hydrocyclone separation system. It offers the following advantages: An upper and lower grinding disc are stacked, with the upper disc rotating under motor drive. Two feed pipes respectively transport heavy sludge and dilution water, assisting the upper and lower grinding discs in breaking up the heavy sludge for subsequent hydrocyclone separation. A connecting frame secures the lower grinding disc and seamlessly connects to the tank cover. A drain hole transports the diluted and broken sludge to the inlet pipe. A cyclone rod rotates within the hydrocyclone for heavy sludge hydrocyclone separation. During the upward swirling of the water, larger particles and other impurities form an outer vortex and, under gravity, deposit towards the coarse feed pipe at the bottom of the hydrocyclone. The filter cover filters and screens smaller impurities. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0020] Example 1, as Figure 1-3 As shown, a heavy sludge hydrocyclone separation system includes a hydrocyclone 1 and a pretreatment component 3. An inlet pipe 2 is installed on the left side of the upper end of the hydrocyclone 1. A cyclone rod 5 is installed inside the hydrocyclone 1. A drive motor 13 is installed in the middle of the upper part of the hydrocyclone 1. The drive end of the drive motor 13 passes through the hydrocyclone 1 and is connected to the cyclone rod 5. A coarse material discharge pipe 6 is provided at the lower end of the hydrocyclone 1. An overflow pipe 8 is installed on the right side of the hydrocyclone 1.
[0021] The pretreatment component 3 includes a barrel cover 31 and a connecting frame 35. The connecting frame 35 is installed below the barrel cover 31, and its lower end is connected to the inner cavity of the liquid inlet pipe 2. A rotating motor is fixedly installed inside the barrel cover 31, and the drive shaft of the rotating motor is connected to the upper grinding disc 32. A feeding pipe 33 is installed in the middle of the upper grinding disc 32. A lower grinding disc 34 is installed inside the connecting frame 35. The upper grinding disc 32 and the lower grinding disc 34 are vertically aligned. Both the lower grinding disc 34 and the connecting frame 35 have liquid outlet holes 36 on their surfaces. The barrel cover 31 and the connecting frame 35 are the same size, and the connecting frame 35 is circular in shape.
[0022] Working principle:
[0023] In use, heavy sludge and dilution water are conveyed to the upper grinding disc 32 and the lower grinding disc 34 through the feeding pipe 33. The upper grinding disc 32 rotates under the drive of the rotating motor, so that the upper grinding disc 32 and the lower grinding disc 34 break up the heavy sludge for subsequent cyclone separation. The broken up and diluted sludge is conveyed to the liquid inlet pipe 2 through the liquid outlet 36. The liquid inlet pipe 2 then sends the sludge to the hydrocyclone 1. The drive motor 13 drives the cyclone rod 5 to rotate in the hydrocyclone 1 for the cyclone separation of heavy sludge. In the process of upward cyclone flow of water, larger particles and other impurities form an external cyclone and are deposited towards the coarse material discharge pipe 6 at the bottom of the hydrocyclone 1 under the action of gravity. During the cyclone flow, the liquid with fewer impurities enters the overflow pipe 8 and is discharged.
[0024] In Example 2, as a further preferred embodiment of Example 1, a reinforcing frame 4 is installed at the lower end of the inlet pipe 2, and the reinforcing frame 4 is connected to the side wall of the hydrocyclone 1. The reinforcing frame 4 and the inlet pipe 2 form a triangle to ensure the stability of the inlet pipe 2 and the pretreatment component 3.
[0025] In Example 3, as a further preferred embodiment of Example 1, a filter cover 7 is installed on the inner surface of the hydrocyclone 1, and the end of the overflow pipe 8 is located inside the filter cover 7. The filter cover 7 can filter and screen smaller impurities.
[0026] In Example 4, as a further preferred embodiment of Example 3, the filter cover 7 is mounted on the inner wall of the hydrocyclone 1 via a connecting plate 11. A waterproof electric push rod 12 is mounted on the connecting plate 11. A cleaning brush ring 10 is movably fitted onto the outer surface of the filter cover 7, and a mounting ring 9 is provided on the outer surface of the cleaning brush ring 10. The telescopic end of the waterproof electric push rod 12 is connected to the mounting ring 9. Therefore, after a period of use, the cleaning brush ring 10 can be moved axially along the filter cover 7 by controlling the waterproof electric push rod 12, thereby effectively preventing impurities from accumulating on the outside of the filter cover 7 and affecting the use of the overflow pipe 8.
[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
