Description

Technical Field

[0001] The utility model relates to the technical field of wastewater filtration, in particular to a solid bubbling rotor sheet for a wastewater filter. Background Art

[0002] Wastewater filters are a key piece of equipment in the pulp manufacturing industry, designed to efficiently treat wastewater, separating and purifying impurities such as fibers, fiber bundles, and sand, allowing wastewater from the papermaking process to be recycled back into the system. The filtered wastewater can also be recycled through an alkali recovery system to recover chemicals for reuse in cooking. This effectively reduces production costs, minimizes resource waste, and improves production efficiency, playing a key role in the sustainable development of the pulp industry.

[0003] The wastewater filter is equipped with a rotor and a screen drum. The screen drum generally uses micropores of about 0.3mm, and the rotor pieces are polygonal or trapezoidal structures, which are different from each other. The manufacturing is relatively complex, the cost is high, and it is easy to wear. After wear, the gap between the screen drum and the rotor increases, the filtration efficiency is greatly reduced, and the screen drum is easily blocked, resulting in high maintenance costs and low filtration efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a solid bubbling rotor sheet for a wastewater filter. It adopts a solid structure and has a more precise spiral distribution, smoother arc transition, gentler and more efficient pulses, and is more wear-resistant as a whole compared to the bubbles formed by traditional stamping.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a solid bubbling rotor sheet for a wastewater filter, comprising a bubbling rotor sheet body and a rotor cylinder, wherein the bubbling rotor sheet body is a solid structure, and the bubbling rotor sheet body has a spherical arc working surface, a spherical arc transition surface, a welding surface, a mounting surface and a positioning surface, wherein the spherical arc working surface is located at the top of the bubbling rotor sheet body, the spherical arc transition surface is located between the welding surface and the spherical arc working surface, the mounting surface is located at the bottom of the welding surface, the positioning surface is located on the surface of the mounting surface, the positioning surface cooperates with the positioning hole bored on the rotor cylinder, and the welding surface is welded and fixed to the cylinder section of the rotor cylinder.

[0006] As a preferred embodiment of the solid bubbling rotor piece for a wastewater filter of the present invention, the mounting surface is a small plane, and the welding surface is a cylindrical plane.

[0007] As a preferred solid bubbling rotor piece for a wastewater filter of the utility model, the spherical arc working surface is a spherical arc surface.

[0008] As a preferred solid bubbling rotor piece for a wastewater filter of the present invention, the spherical arc transition surface adopts a spherical arc shape and smoothly transitions with the spherical arc working surface.

[0009] As a preferred solid bubbling rotor piece for a wastewater filter of the present invention, the bubbling rotor piece body is distributed on the surface of the rotor cylinder in a spiral form.

[0010] As a preferred solid bubbling rotor piece for a wastewater filter of the present invention, the bubbling rotor piece body is formed by casting.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model has a spherical smooth surface, and its structural shape has better streamline and better fluid properties. The solid bubbling rotor piece body is distributed on the surface of the rotor cylinder in a spiral form, which can make the rotor produce a gentler and more efficient turbulent effect during rotation. The smooth outer structure of the bubbling rotor piece body can reduce the resistance to rotor rotation and make the rotor rotation more stable, so that the fiber can be better separated from the water, and a good positive pressure effect can be generated, so that qualified water can better enter the sieve drum micropores; and the bubbling rotor piece body can generate more regular and efficient positive and negative pressure pulses to clean the fibers around the sieve drum sieve holes, thereby cleaning the sieve drum micropores, so that the screening and purification efficiency of the rotor can also be improved.

[0013] 2. The traditional bubbling rotor is formed by stamping. Due to the characteristics of stamping, the head of the bubble extends more violently, resulting in a thinner working surface and a hollow interior. Especially in the recently widely used chemical mechanical pulp and waste paper pulp lines, the pulp characteristics are relatively hard. After a period of use, the working surface will be worn through and the service life is short. The utility model adopts a solid bubbling rotor sheet body structure, which has a more precise spiral distribution and a smoother arc transition than the bubble formed by traditional stamping. The generated pulse is gentler and more efficient, and the overall wear resistance is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figure 1-3A solid bubbling rotor sheet for a wastewater filter comprises a bubbling rotor sheet body 1 and a rotor barrel 2. The bubbling rotor sheet body 1 is a solid structure. The bubbling rotor sheet body 1 has a spherical arc working surface 101, a spherical arc transition surface 102, a welding surface 103, a mounting surface 104 and a positioning surface 105. The spherical arc working surface 101 is located at the top of the bubbling rotor sheet body 1, the spherical arc transition surface 102 is located between the welding surface 103 and the spherical arc working surface 101, the mounting surface 104 is located at the bottom of the welding surface 103, and the positioning surface 105 is located on the surface of the mounting surface 104. The positioning surface 105 cooperates with the positioning hole bored on the rotor barrel 2, and the welding surface 103 is welded and fixed to the barrel section of the rotor barrel 2.

[0019] The bubbling rotor piece body 1 uses a spherical arc to transition to the spherical arc working surface 101, forming a closed hemispherical structure. The overall transition is very smooth and has better fluid properties, which can reduce the resistance of the rotor operation, thereby achieving energy-saving effects. The solid design can generate continuous and stable shear force and eddy current, making it easier to separate the fibers and fixed particles in the slurry from the liquid part, thereby improving the overall screening ability of the rotor. The bubbling rotor using this solid bubbling rotor piece body 1 can improve stable and continuous positive and negative pressure pulses through its high-speed rotation, which can effectively prevent the accumulation of solid particles around the filter holes on the screen drum. , which can continuously clean the surface of the screen drum and maintain the continuity and stability of the screening process. The positioning surface 105 cooperates with the rotor positioning hole to make the distribution of the rotor bubbling rotor sheet body 1 more accurate. At the same time, the positioning surface 105 also makes the bottom of the bubbling rotor sheet body 1 have a positioning pin structure, which can be positioned more easily and accurately. Through the setting of the mounting surface 104, the bubbling rotor sheet body 1 does not need to follow the change of the diameter of the rotor cylinder 2, and can be used for a variety of equipment of different sizes. The welding surface 103 can provide a more regular cylindrical welding space for welding, making the welding combination of the bubbling rotor sheet body 1 and the rotor more firm and stable.

[0020] Furthermore, the mounting surface 104 is a small plane, and the welding surface 103 is a cylindrical plane;

[0021] The small facet can be closely fitted with the small facet bored from the rotor cylinder 2 , and the cylindrical plane welding surface 103 can make the bubbling rotor sheet body 1 more firmly installed.

[0022] Furthermore, the spherical arc working surface 101 is a spherical arc surface;

[0023] The spherical arc surface is smooth and has better fluid properties. During the screening process, it can produce a gentler and more efficient turbulent effect.

[0024] Furthermore, the spherical arc transition surface 102 adopts a spherical arc shape and smoothly transitions with the spherical arc working surface 101;

[0025] This design enables the spherical arc transition surface 102 to cooperate with the spherical arc working surface 101 to produce a uniform negative pressure pulse effect; through the two-section spherical arc design of the spherical arc working surface 101 and the spherical arc transition surface 102, a very good negative pressure pulse effect can be produced, which can better clean the fibers in the sieve holes, greatly reduce the clogging of the sieve holes, and eliminate the situation of stopping the machine for cleaning due to clogging of the sieve holes, thereby increasing the filtration efficiency.

[0026] Furthermore, the bubbling rotor sheet body 1 is distributed on the surface of the rotor cylinder 2 in a spiral form;

[0027] The spiral distribution can make the rotor produce a gentler and more efficient turbulence effect during the rotation process, and the precise spiral arrangement, coupled with the overall spherical design of the solid bubbling rotor body 1, makes the overall rotation of the rotor more stable and has smaller rotational resistance, allowing the rotor to achieve efficient screening and washing effects at relatively low energy consumption, thereby reducing the energy consumption of the entire screening system.

[0028] Furthermore, the bubbling rotor plate body 1 is formed by casting;

[0029] With this design, the structure and size of the bubbling rotor body 1 are stable and easy to control, and the manufacturing is relatively simple and can be mass-produced.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
