Technical Field

[0001] This utility model belongs to the technical field of submersible mixers, specifically a submersible mixer with a cutting function. Background Technology

[0002] In wastewater treatment, industrial wastewater treatment, and river dredging, submersible mixers are key equipment for achieving water circulation and mixing, and their performance directly affects treatment efficiency. However, in practical applications, water often contains a large amount of fibrous impurities, ribbon-like materials, and soft biomass. These substances can easily become entangled in the mixing blades or enter the equipment, leading to decreased mixing efficiency, motor overload, or even equipment damage, increasing maintenance costs and downtime.

[0003] To address this issue, submersible mixers with cutting capabilities have become a key research focus. Their core requirement is to efficiently cut away impurities while simultaneously achieving mixing, and to balance structural stability and ease of maintenance. Traditional cutting-type submersible mixers often suffer from insufficient cutting efficiency, such as incomplete cutting by a single set of blades and complex disassembly and assembly of the cutter head, requiring the disassembly of multiple components and resulting in cumbersome operation. Therefore, we propose a submersible mixer with cutting capabilities. Utility Model Content

[0004] The purpose of this invention is to provide a submersible mixer with a cutting function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a submersible mixer with a cutting function, comprising a submersible mixer, a turntable installed at the bottom of the mixing blades of the submersible mixer, a support plate placed at the bottom of the turntable, a block connected between the mixing blades of the submersible mixer and the turntable, a rotating shaft connected between the turntable and the support plate, a support ring installed on the outer ring of the support plate, a guide sleeve installed on the outer ring of the support ring, an anti-loosening bolt connected between the support ring and the guide sleeve, passive cutting blades evenly arranged between the support plate and the support ring, and active cutting blades evenly arranged on the outer side of the turntable, the active cutting blades corresponding to the passive cutting blades.

[0006] Preferably, the bottom of the mixing blades of the submersible mixer is provided with a square groove, and the square block is set on the top of the turntable and inserted into the square groove.

[0007] Preferably, the rotating shaft is located at the bottom of the turntable, and a connecting hole is provided at the top of the support plate, with the rotating shaft disposed within the connecting hole.

[0008] Preferably, a wear-resistant sealing ring is placed between the support plate and the turntable, and the wear-resistant sealing ring is sleeved on the outside of the rotating shaft.

[0009] Preferably, connecting columns are evenly arranged between the submersible mixer and the guide sleeve, and the mixing blades and active cutting blades of the submersible mixer are located inside the guide sleeve.

[0010] Preferably, the bottom of the guide sleeve is provided with an annular groove, the annular groove penetrates the inner side of the guide sleeve, the support ring is disposed in the annular groove, the outer side of the support ring is uniformly provided with threaded holes, the outer side of the annular groove is uniformly provided with through holes, and the anti-loosening bolt is threaded through the through holes and threaded holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by forming a "scissor-like" cooperation structure between the active cutting blade and the passive cutting blade, the active cutting blade moves relative to the passive cutting blade as it rotates with the stirring fan blade, cutting the impurities entering the guide sleeve. Compared with the cutting method of a single set of rotating blades, it can cut off stubborn impurities such as fibers and strips more thoroughly, greatly reducing the risk of entanglement. Furthermore, after unscrewing the anti-loosening bolt, the passive and active cutting blades can be quickly removed from the guide sleeve, thereby achieving the effect of quick disassembly and replacement of the blades, significantly simplifying the replacement and maintenance process of the cutter head, and reducing maintenance time and labor costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A submersible mixer with cutting function includes a submersible mixer 1. A turntable 17 is installed at the bottom of the mixing blades of the submersible mixer 1. A support plate 14 is placed at the bottom of the turntable 17. A block 19 connects the mixing blades of the submersible mixer 1 to the turntable 17. A rotating shaft 18 connects the turntable 17 and the support plate 14. A support ring 21 is installed on the outer ring of the support plate 14. A guide sleeve 12 is installed on the outer ring of the support ring 21. An anti-loosening bolt 1 connects the support ring 21 and the guide sleeve 12. 3. Passive cutting blades 15 are uniformly fixed between the support plate 14 and the support ring 21. Active cutting blades 16 are uniformly fixed on the outer side of the turntable 17. The active cutting blades 16 correspond to the passive cutting blades 15. A square groove is opened at the bottom of the mixing fan blade of the submersible mixer 1. A block 19 is fixedly set on the top of the turntable 17 and inserted into the square groove. The rotating shaft 18 is fixedly set on the bottom of the turntable 17. A connecting hole is opened on the top of the support plate 14. The rotating shaft 18 is rotatably set in the connecting hole.

[0020] A wear-resistant sealing ring 2 is placed between the support plate 14 and the turntable 17. The wear-resistant sealing ring 2 is sleeved on the outside of the rotating shaft 18. Lubricant can be injected into the connection hole of the support plate 14 to reduce the wear of the rotating shaft 18 in the connection hole. The wear-resistant sealing ring 2 seals the connection gap between the support plate 14 and the turntable 17. A connecting column 11 is evenly fixed between the submersible mixer 1 and the guide sleeve 12. The mixing blade and the active cutting blade 16 of the submersible mixer 1 are located inside the guide sleeve 12. An annular groove is opened at the bottom of the guide sleeve 12. The annular groove penetrates the inner side of the guide sleeve 12. The support ring 21 is slidably disposed in the annular groove. Threaded holes are evenly opened on the outer side of the support ring 21. Through holes are evenly opened on the outer side of the annular groove. Anti-loosening bolts 13 are screwed through the through holes and threaded holes. The anti-loosening bolts 13 are screwed through the through holes of the guide sleeve 12 and threaded holes of the support ring 21 to fix the support ring 21 in the annular groove of the guide sleeve 12.

[0021] Working principle: Place the turntable 17 at the bottom of the mixing blades of the submersible mixer 1, and insert the block 19 into the square groove. Then, place the support plate 14 at the bottom of the turntable 17, and insert the rotating shaft 18 into the connecting hole. At this time, the support ring 21 is located in the annular groove of the guide sleeve 12. Then, the anti-loosening bolt 13 passes through the through hole of the guide sleeve 12 and is screwed into the threaded hole of the support ring 21, thereby fixing the support ring 21 in the annular groove of the guide sleeve 12. This fixes the position of the passive cutting blade 15 and the support plate 14, thus making the turntable 17 stably limited on the support plate 1. Between the 4 and the mixing blades of the submersible mixer 1, when the mixing blades of the submersible mixer 1 rotate, the turntable 17 can be driven to rotate through the block 19. The turntable 17 is supported by the rotating shaft 18 to rotate stably. Then, the turntable 17 drives the active cutting blade 16 to rotate on top of the passive cutting blade 15. By adopting a "scissor-type" cooperation structure between the active cutting blade 16 and the passive cutting blade 15, the active cutting blade 16 forms a relative movement with the passive cutting blade 15 when it rotates with the mixing blades of the submersible mixer 1, and cuts the solid impurities that enter the guide sleeve 12.

[0022] After unscrewing the anti-loosening bolt 13, the support ring 21 can be moved downwards to separate from the guide sleeve 12. The guide sleeve 12 drives the support plate 14 to move downwards to separate from the turntable 17 through the passive cutting blade 15. At this time, the turntable 17 and the active cutting blade 16 can be moved downwards to be removed from the guide sleeve 12, thereby achieving the effect of quick disassembly and replacement of the cutting tool.
