Description

Technical Field

[0001] This utility model relates to the field of hydrocyclone technology, and in particular to an anti-clogging blade assembly for a sludge reduction hydrocyclone. Background Technology

[0002] A hydrocyclone separator is a device that separates solid particles from a suspension using the principle of centrifugal sedimentation. The main body of the device consists of a cylinder and a cone. The suspension enters the cylinder tangentially through the inlet pipe and moves downwards in a spiral motion. Solid particles, under the influence of inertial centrifugal force, are thrown against the wall of the separator and descend with the downward swirling flow to the outlet at the bottom of the cone. The concentrated liquid discharged from the bottom is called the underflow. The clear liquid or liquid containing fine particles forms an upward inner swirling flow and is discharged from the central pipe at the top, called the overflow.

[0003] However, it was found that when using sludge reduction hydrocyclones, weeds, plant roots and various strip-shaped entanglements mixed in the wastewater tend to get tangled on the cyclone blades or drive shaft when the guide blades rotate. As the entanglements accumulate, they gradually hinder the rotation of the blades and may even cause power transmission to be blocked, leading to equipment jamming. Utility Model Content

[0024] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-5 The anti-clogging blade assembly of the sludge reduction hydrocyclone separator includes a connecting seat 1, which is fixed inside the sludge reduction hydrocyclone separator by bolts or welding, and a cyclone blade body 3 connected to the connecting seat 1 via a lower base 2. It should be noted that the function of the cyclone blade body 3 is to separate sludge from wastewater, which is existing technology. The connecting seat 1 contains a power source, preferably a servo motor, for driving the rotation of the cyclone blade body 3. An upper base 4 is located above the connecting seat 1, and an anti-winding mechanism is located above the upper base 4. The anti-winding mechanism includes two symmetrically arranged hollow turntables 12, which are rotatably connected. Each hollow turntable 12 has several cutting blades 14 on its sidewall for cutting weeds, plant roots, and other strip-shaped entanglements. It should be noted that the cutting blades 14 on the two hollow turntables 12 are staggered. The connecting seat 1 contains a drive mechanism for driving the anti-winding mechanism.

[0026] During the operation of the hydrocyclone separator, the two hollow turntables 12 are driven by the drive mechanism to move in opposite directions. Each hollow turntable 12 drives multiple cutting blades 14 on it to rotate. The two cutting blades 14, which are close to each other, cut the weeds, plant roots and other strip-shaped entangled materials in the sludge in a manner similar to scissors, so as to avoid them from getting tangled on the main body of the hydrocyclone blade 3 and the shaft that drives the main body of the hydrocyclone blade 3 to rotate, thus preventing blockage.

[0027] Furthermore, a mounting frame 15 is provided at the bottom of the cyclone blade body 3, and a plurality of extension rods 16 are provided on the side wall of the mounting frame 15. Each extension rod 16 is provided with a scraper 17 at the end away from the mounting frame 15. It should be noted that the length of the extension rod 16 is adapted to the size of the mud and sand outlet in the cyclone separator, and the extension rod 16 is preferably connected to the mounting frame 15 and the scraper 17 by welding. This allows the mounting frame 15 to rotate during the rotation of the cyclone blade body 3, thereby causing the extension rod 16 to drive the scraper 17 to rotate at the edge of the mud and sand outlet of the cyclone separator, thus avoiding the problem of mud and sand accumulation and blockage.

[0028] Furthermore, the drive mechanism includes a first rotating shaft 6 rotatably connected to the upper base 4, and the connecting seat 1 is provided with a power source for driving the first rotating shaft 6 to rotate, preferably a servo motor. The first rotating shaft 6 is provided with a driving bevel gear 7, which meshes with a first transmission bevel gear 10. The first transmission bevel gear 10 is connected to a second transmission bevel gear 11 through a second rotating shaft 9. Each hollow turntable 12 has a third transmission bevel gear 13 on its inner wall. The second transmission bevel gear 11 meshes with the third transmission bevel gear 13, and the second transmission bevel gear 11 is located in the middle position between the two third transmission bevel gears 13.

[0029] The servo motor drives the first rotating shaft 6 to rotate, which in turn drives the active bevel gear 7 to rotate, which in turn drives the first transmission bevel gear 10 that meshes with it to rotate. The first transmission bevel gear 10 drives the second rotating shaft 9 to rotate, which in turn drives the second transmission bevel gear 11 to rotate. The second transmission bevel gear 11 then drives the third transmission bevel gear 13 that meshes with it to rotate, which in turn drives the two hollow turntables 12 to rotate in opposite directions.

[0030] Furthermore, two limiting blocks 5 are provided above the upper base 4 to limit the movement of the two hollow turntables 12 and prevent them from moving up and down.

[0031] Furthermore, a support frame 8 is provided between the two limiting blocks 5, and the second rotating shaft 9 is rotatably connected to the support frame 8, which can prevent the second rotating shaft 9 from revolving.

[0032] Furthermore, the hollow turntable 12 and the insert block 19 are fixed together by bolts 20. The hollow turntable 12 and the insert block 19 are provided with matching threaded grooves for connecting and installing the insert block 19 onto the hollow turntable 12. The cutting blade 14 can be removed from the hollow turntable 12 by tools and the dulled cutting blade 14 can be replaced.

[0033] Furthermore, a limiting mechanism is provided between the hollow turntable 12 and the cutting blade 14; the limiting mechanism includes an insert block 19 fixedly connected to the end of the cutting blade 14, preferably connected by welding. The insert block 19 is provided with a strip-shaped adapter block 21, and the hollow turntable 12 is provided with a slot 18 that matches the insert block 19 and the strip-shaped adapter block 21. It should be noted that the purpose of the strip-shaped adapter block 21 is to limit the insertion of the insert block 19 after it is inserted into the slot 18, so as to avoid the problem that the hollow turntable 12 and the part connected to the bolt 20 are subjected to force and the edge of the thread groove is worn when the hollow turntable 12 rotates instantaneously and drives the cutting blade 14 on the insert block 19 to rotate.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
