[0001] The utility model belongs to the technical field of cleaning blades, in particular to a cleaning blade and a raw material mixing barrel. Background Art

[0002] In modern industrial production, efficient and environmentally friendly material handling and processing technology is one of the key factors driving the development of various industries. Especially in the fields of chemical industry, food processing, pharmaceutical industry, etc., the mixing and stirring process of raw materials is crucial to the quality and production efficiency of the final product. Traditional mixing equipment mostly uses single-structure mixing blades. These blades gradually show their limitations during long-term operation due to material wear, low power efficiency and difficulty in thorough cleaning. In recent years, with the advancement of materials science and the improvement of production environment requirements, the improvement of mixing blades and their supporting containers has become a research hotspot.

[0003] Most existing mixing blades are made of metal materials. Although they are strong, they are prone to corrosion and wear when handling corrosive or highly abrasive materials, especially serious wear and tear on the barrel wall, which shortens the service life. In addition, the single-structure blade is prone to form a dead zone during the mixing process, especially in the lower part, where raw materials are piled up and difficult to mix, reducing the mixing uniformity and affecting the product quality. Therefore, we propose a cleaning blade and a raw material mixing barrel. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a cleaning blade and a raw material mixing barrel. By providing an upper and lower double blades, the mixing is more uniform. By providing a ceramic wear-resistant plate and facilitating replacement, the wear resistance is enhanced. The overall strength of the lower blade is high, and the mixing can be more thorough.

[0005] The utility model is implemented as follows: a cleaning blade comprises an upper blade body, wherein the upper blade body is mounted on a main shaft, the lower part of the main shaft is detachably connected to the lower blade body via a connecting piece, the upper blade body comprises a supporting blade, the upper part of the supporting blade is connected to a reinforcing rib via bolts, the left side of the reinforcing rib is connected to a ceramic wear-resistant plate via bolts, the lower blade body comprises an upper mounting ring, a plurality of inclined plates are welded to the lower part of the upper mounting ring, and a lower mounting ring is welded to the lower part of the inclined plate.

[0006] Optionally, a reinforcing shaft is welded between the upper mounting ring and the lower mounting ring, and a screw hole is opened on the upper portion of the reinforcing shaft.

[0007] Optionally, the connecting member includes a first sleeve, which is connected to the lower end of the main shaft through bolts, and a plurality of connecting plates are welded to the lower part of the first sleeve, and the connecting plates are connected to the reinforcing shaft through bolts.

[0008] Optionally, a first water flow channel and a second water flow channel are provided between two adjacent inclined plates, and the width of the first water flow channel is greater than that of the second water flow channel.

[0009] Optionally, a fixed reinforcement ring is welded to the upper portion of the support leaf, and a second sleeve is welded to the upper portion of the support leaf.

[0010] Optionally, the second sleeve is connected to the main shaft via bolts, and the support leaf is provided with an opening for the main shaft to pass through.

[0011] In addition, the utility model also provides a raw material mixing barrel, including the cleaning blades and a mixing barrel body, wherein a motor is fixedly connected to the upper portion of the mixing barrel body, and the motor is connected to the main shaft via a coupling.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The modularity and maintainability of the blade structure are achieved by adopting a fixed connection between the upper blade and the main shaft, combined with the detachable design of the lower blade through the connector. This design allows for quick replacement of damaged parts in the face of different working conditions or wear conditions, reducing downtime and improving production efficiency. At the same time, the modular design facilitates flexible adjustment of the blade combination according to different material characteristics and mixing requirements, improving the versatility and adaptability of the equipment.

DETAILED DESCRIPTION

[0025] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown, a cleaning blade provided by an embodiment of the utility model includes an upper blade body 3, which is mounted on a main shaft 1, and the lower part of the main shaft 1 is detachably connected to a lower blade body 2 via a connecting piece 4, the upper blade body 3 includes a supporting leaf 31, the upper part of the supporting leaf 31 is connected to a reinforcing rib 34 via bolts, and the left side of the reinforcing rib 34 is connected to a ceramic wear-resistant plate 32 via bolts, and the lower blade body 2 includes an upper mounting ring 21, and a plurality of inclined plates 23 are welded to the lower part of the upper mounting ring 21, and a lower mounting ring 22 is welded to the lower part of the inclined plate 23.

[0027] First, the fixed installation of the upper blade 3 and the main shaft 1, and the detachable design of the lower blade 2 through the connector 4, reflect the application of modular thinking. This design is not only convenient for maintenance and replacement of worn parts, but also means that the blade configuration can be quickly adjusted according to different mixing tasks, which enhances the flexibility and versatility of the system and effectively solves the problems of difficult maintenance and poor adaptability of traditional integrated blades.

[0028] Secondly, the reinforcement ribs 34 are added to the support blades 31, and the ceramic wear-resistant plates 32 are fixed by bolts, which is a major breakthrough in the wear resistance of the utility model. The introduction of the ceramic wear-resistant plates 32 utilizes the excellent wear resistance of ceramic materials, significantly improves the durability of the blades when handling highly abrasive materials, reduces the frequent replacement due to wear, and reduces long-term operating costs. The combined design of the reinforcement ribs 34 and the ceramic wear-resistant plates 32 not only strengthens the blade structure, but also cleverly solves the technical problem of high strength and high wear resistance.

[0029] Furthermore, in the structural design of the lower blade body 2, the upper mounting ring 21 and the lower mounting ring 22 are formed by welding inclined plates 23, and the lower mounting ring 22 is further welded under each inclined plate 23. This design not only optimizes the material flow trajectory during stirring and reduces the stirring dead angle, but also enhances the mixing uniformity through the special arrangement of the inclined plates 23.

[0030] A reinforcing shaft 24 is welded between the upper mounting ring 21 and the lower mounting ring 22 , and a screw hole is formed at the upper portion of the reinforcing shaft 24 .

[0031] This design aims to enhance the overall rigidity and stability of the blade assembly, especially the shear force and torsion during high-speed mixing. The reinforcing shaft 24 is the core load-bearing structure, firmly fixed between the mounting rings by welding, and a screw hole is opened on its upper part to provide a convenient interface for connecting other components. This design goes beyond the traditional single blade fixing mode and significantly improves the reliability and service life of the mixing equipment under complex working conditions.

[0032] The connecting member 4 includes a first sleeve 42 , which is connected to the lower end of the main shaft 1 through bolts. A plurality of connecting plates 41 are welded to the lower portion of the first sleeve 42 , and the connecting plates 41 are connected to the reinforcing shaft 24 through bolts.

[0033] A novel adjustable fastening mechanism is formed by bolting the first sleeve 42 to the main shaft 1, supplemented by the cooperation between the connecting plate 41 and the reinforcing shaft 24. This design not only simplifies the installation and disassembly process of the lower blade 2, but also effectively disperses the working stress through the distributed loading of the connecting plate 41, avoiding structural damage caused by local overload, reflecting the rationality and practicality of the design, and solving the technical problem that the traditional fixing method is easily damaged under complex dynamic loads.

[0034] A first water flow channel 25 and a second water flow channel 26 are provided between two adjacent inclined plates 23. The width of the first water flow channel 25 is greater than that of the second water flow channel 26. The width of the first water flow channel 25 is greater than two centimeters, and the width of the second water flow channel 26 is greater than one centimeter. The larger width can prevent blockage.

[0035] The first water flow channel 25 and the second water flow channel 26 of different widths are arranged between adjacent inclined plates 23, which is an ingenious design based on the principle of fluid mechanics. The wider first water flow channel 25 helps to quickly discharge large particles, while the narrower second water flow channel 26 increases the flow rate to achieve strong flushing of the blade surface, effectively improving the cleaning efficiency. This design targets the pain point that traditional mixing equipment is difficult to clean thoroughly. Through the differentiated design of the flow channel, efficient self-cleaning is achieved, manual intervention is reduced, and the hygiene standards and use efficiency of the equipment are improved.

[0036] A fixing reinforcement ring 33 is welded to the upper portion of the support leaf 31 , and a second sleeve 35 is welded to the upper portion of the support leaf 31 .

[0037] The second sleeve 35 is connected to the main shaft 1 by bolts, and the support leaf 31 is provided with an opening for the main shaft 1 to pass through.

[0038] In addition, the utility model further provides a raw material mixing barrel, including cleaning blades and a mixing barrel body 5, the upper part of which is fixedly connected with a motor 6, and the motor 6 is connected to the main shaft 1 through a coupling.

[0039] When in use, the working principle of the utility model is as follows: first, the main shaft 1 drives the lower blade 2 to rotate through the lower connecting piece 4, and the inclined plate 23 on the lower blade 2 generates a complex flow field during rotation, effectively stirring the raw materials in the barrel and improving the mixing efficiency. Among them, the reinforcing shaft 24 welded between the upper mounting ring 21 and the lower mounting ring 22 not only strengthens the overall structure, but the screw holes preset on the upper part also provide a convenient access point for additional components, enhancing the scalability of the system.

[0040] At the same time, the connecting piece 4 is uniquely designed. The first sleeve 42 is firmly connected to the lower end of the main shaft 1 by bolts to ensure the stability of power transmission, and several connecting plates 41 welded at the bottom are connected to the reinforcing shaft 24 by bolts. This design effectively disperses the load during the mixing process and improves the durability and reliability of the system.

[0041] During the mixing process, the dual-channel design between adjacent inclined plates 23, namely the first water flow channel 25 and the second water flow channel 26, plays an important role. The first water flow channel 25 is relatively wide, which is convenient for quickly discharging larger particles or lumps generated during the mixing process, while the narrower second water flow channel 26 forms a strong flushing on the blade surface due to the increased flow rate, which significantly improves the self-cleaning ability and reduces the downtime for maintenance.

[0042] In addition, the upper part of the support blade 31 is fixed with the reinforcing ring 33 and the second sleeve 35 by welding, which not only strengthens the structural strength of the blade, but also ensures the firm positioning and rotational stability of the blade assembly by directly connecting the second sleeve 35 to the main shaft 1 through bolts. The opening design on the support blade 31 allows the main shaft 1 to pass through smoothly, optimizes the assembly process, and ensures the continuity and safety of the mixing operation.

[0043] In summary, the utility model achieves multiple goals of efficient stirring, self-cleaning, easy maintenance and structural strengthening through the above-mentioned structural design, significantly improves the comprehensive performance of the stirring equipment, and meets the high requirements for efficiency, cleanliness and durability in modern industrial production.
