Description

[0002] The powder-liquid mixing process is widely used in many fields, especially an essential process in the industrial raw material processing link. For the pulp industry, in order to make the pulp meet the requirements of uniformity and refinement, an efficient pulping system is usually selected. As the core components of the efficient pulping system, the structural design of the rotor impeller and the stator is the key to determining whether the pulp can be evenly dispersed.

[0003] Currently, the existing rotor impellers in the industry solutions are usually made of metal materials, which have poor corrosion resistance and wear resistance. Furthermore, adding a surface coating on the outside of the rotor impeller during the research and development process can improve the corrosion resistance and wear resistance to a certain extent, prevent the generation of metal particles and avoid cavitation and corrosion. However, due to the too high shear linear velocity on the shear side during the rotation of the rotor impeller and the strong impact friction force of the pulp, the life of the surface coating is not long, it is easy to fall off, and metal particles will also be generated, which affects the quality of the pulp and the life of the rotor impeller cannot be guaranteed.

[0004] Therefore, how to ensure the production quality of the pulp and the service life of the rotor impeller is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0034] The following will describe in detail the embodiments of the present invention. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0035] The core of the present utility model is to provide a rotor impeller assembly and an efficient pulping system, which can ensure the production quality of the pulp and the service life of the rotor impeller.

[0036] In order to enable those skilled in the art to better understand the technical solutions provided by the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Specifically, please refer to Figures 1-7 , a rotor impeller assembly provided by the present utility model includes a rotor main body 100, a plurality of blade sleeve blocks 200, and a rotor cover plate 300.

[0038] The rotor main body 100 includes a main board 101 and a plurality of sleeve block fixing columns 102 provided at least on one side of the main board 101. The main board 101 has a transmission shaft mounting hole 103 penetrating through both ends thereof. The shape of the main board 101 is usually circular, and other shapes such as oval or others can also be selected according to the actual situation. The shape of the sleeve block fixing column 102 can be cylindrical, and can also be conical, rectangular or other shapes. When it is conical, the thinner end is inserted into the blade sleeve block, and the thicker end is connected to the main board 101. The main board 101 and the plurality of sleeve block fixing columns 102 are manufactured by welding connection or integral casting molding process.

[0039] The blade sleeve blocks 200 are all made of non-metallic materials. At least one sleeve block through hole 201 for inserting the sleeve block fixing column 102 is provided on the blade sleeve block 200. A shear groove for dispersing and shearing the pulp is formed between the plurality of blade sleeve blocks 200.

[0040] The rotor cover plate 300 is used to connect the sides of the plurality of blade sleeve blocks 200 facing away from the rotor main body 100, so that the connection of the ends of the blade sleeve blocks 200 is more stable.

[0041] For a rotor impeller assembly provided by the present utility model, by providing a plurality of sleeve block fixing columns 102 on the main board 101 of the rotor main body 100, one end of the blade sleeve block 200 is sleeved on the sleeve block fixing column 102, and the other ends of the blade sleeve blocks 200 are connected together through the rotor cover plate 300 to form a rotor impeller capable of uniformly dispersing the pulp. Also, the blade sleeve blocks 200 that realize the main mixing function are made of non-metallic materials, changing the material in contact with the pulp, improving corrosion resistance and wear resistance, thereby increasing the shear efficiency, ensuring the production quality of the pulp and the service life of the rotor impeller. At the same time, by adopting the form of inserting the blade sleeve block 200 and the sleeve block fixing column 102, the overall processing difficulty and cost of the blade sleeve block 200 can be reduced, the qualified rate of the finished product can be improved, which has a positive significance for cost control.

[0042] The above settings can simultaneously solve the defects of poor wear resistance of the metal rotor impeller and short service life of the non-metallic coating.

[0043] In a specific embodiment, a plurality of sleeve block fixing columns 102 are provided on one side of the main board 101, or a plurality of sleeve block fixing columns 102 are provided on both sides of the main board 101. Specifically, it can be selected according to the actual required mixing degree and working efficiency.

[0044] Furthermore, the plurality of sleeve block fixing columns 102 are arranged in multiple inner and outer circles. The multiple circles can be concentrically arranged. The sleeve block fixing columns 102 on each circle are equally spaced, the adjacent circles are equally spaced, and the shear grooves on the adjacent circles can be arranged opposite to each other or staggered.

[0045] Furthermore, one end of at least two blade sleeves 200 is connected and the other end is separated to form a sleeve block assembly, and a shear groove is formed between the other ends of the adjacent two blade sleeves 200.

[0046] It should be noted that one blade sleeve 200 is a minimum blade unit for realizing slurry shearing. It can be independently arranged for multiple blade sleeves 200, or at least two blade sleeves 200 can be connected into one body. Preferably, as Figure 3 shown, a sleeve block assembly is formed by connecting two blade sleeves 200 into one body, and the shear groove on the sleeve block assembly is a U-shaped groove. A sleeve through hole 201 is provided at one end of the blade sleeve 200, and the sleeve block fixing column 102 passes through the sleeve through hole 201 of the blade sleeve 200, so that one end face of the blade sleeve 200 fits against the surface of the rotor main body 100.

[0047] In the first specific embodiment, the rotor main body 100 is made of a metal material to form the rotor main body. Both the main board 101 and the sleeve block fixing column 102 are made of a metal material that is easy to process. The sleeve block fixing column 102 is used as the inner layer, and the outer layer is sleeved with a blade sleeve 200 made of a non-metal material with high hardness and good wear resistance, which can resist the friction and corrosion of the slurry.

[0048] In the second specific embodiment, it is also possible to adopt the method in which both the rotor main body 100 and the blade sleeve 200 are made of non-metal materials. Relatively speaking, the structural strength of the rotor main body 100 made of a metal material is higher than that of the rotor main body 100 made of a non-metal material.

[0049] Among them, the non-metal material used for the blade sleeve 200 can specifically be a ceramic material. In the first specific embodiment, the sleeve block fixing column 102 and the blade sleeve 200 of the rotor impeller assembly are composed of two inner and outer layers. The inner layer is made of a metal material that is easy to process, is easily subject to the friction and corrosion of the slurry, and the shear side outer ring that is easy to process can be made of a ceramic material with high hardness and good wear resistance. When it is necessary to replace the outer blade sleeve 200, it can be replaced by disassembling and reinstalling, which can reduce the overall processing rejection rate and processing cost of the outer material.

[0050] The non-metallic material in this application can be a ceramic material, a plastic material, or other composite materials, and can be adaptively selected according to actual needs.

[0051] In a specific embodiment, the rotor cover plate 300 is in an annular structure or a disc shape. A number of cover plate fixing keys 301 are arranged at intervals on the annular structure, and an installation position for embedding the blade sleeve block 200 is formed between two adjacent cover plate fixing keys 301. The cover plate fixing keys 301 protruding from the surface of the cover plate are designed on the rotor cover plate 300 for positioning the blade sleeve block 200.

[0052] When multiple sleeve block fixing columns 102 are arranged in multiple inner and outer circles, the number of rotor cover plates 300 is consistent with the number of circles of the sleeve block fixing columns 102.

[0053] The cover plate fixing keys 301 can integrally exist on the rotor cover plate 300 and are used to insert into the gap between two blade sleeve blocks 200.

[0054] In a specific embodiment, the blade sleeve block 200 is connected to the rotor cover plate 300 and the rotor body 100 by glue. After each component is processed, after the blade sleeve block 200 is positioned by combining with the sleeve block through hole 201 and the sleeve block fixing column 102, all the blade sleeve blocks 200 are sequentially sleeved on the rotor body 100. After all the blade sleeve blocks 200 on one side of the rotor body 100 are sleeved, glue is applied at the joint, and then the corresponding rotor cover plate 300 is buckled. After fine-tuning the position to make it fit for installation, glue is applied again at the joint. After it is firmly combined, the rotor body 100 is reversed, and the rotor body 100, the blade sleeve block 200, and the rotor cover plate 300 on the other side are also sequentially installed and combined with glue.

[0055] The present utility model also provides an efficient pulping system, including a stator and a rotor impeller assembly as in the above specific embodiment.

[0056] Obviously, the efficient pulping system with the above rotor impeller assembly has the same beneficial effects and will not be elaborated here.

The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
