Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a multi-layer filtration wastewater sedimentation agent mixing device. Background Technology

[0002] Wastewater treatment is a crucial aspect of environmental protection, and chemical sedimentation with reagents is a commonly used chemical treatment method. Multi-layer filtration-type wastewater sedimentation reagent mixing equipment, as a key device in this type of treatment, integrates functions such as filtration, reagent dosing, and mixing reaction, and is widely used in the purification of industrial wastewater and domestic sewage.

[0003] During the operation of this type of equipment, the filter located above the motor plays a crucial role in intercepting impurities and larger particles in the polluted air, preventing impurities from entering the motor and affecting the mixing effect of the reagents or causing damage to the motor.

[0004] However, as the equipment operates for extended periods, the filter screen inevitably becomes clogged or damaged, requiring regular cleaning and replacement. In existing equipment structures, the installation and fixing methods for the filter screen are often relatively simple, such as using bolts, pressure plates, or clamps to secure it to the chamber or motor flange.

[0005] Traditional fastening methods reveal significant shortcomings when filter replacement is required. Maintenance personnel must loosen and remove multiple fasteners one by one, which is particularly inconvenient, time-consuming, and labor-intensive, especially in the confined and potentially damp interior of the equipment. Small parts (such as bolts and nuts) are also prone to being lost or falling off, requiring realignment and tightening upon reinstallation. The entire maintenance process is cumbersome, leading to extended equipment downtime and severely impacting the continuity of wastewater treatment and overall operational efficiency.

[0006] Therefore, this utility model proposes a multi-layer filtration wastewater sedimentation reagent mixing device to overcome the shortcomings of the prior art. Utility Model Content

[0008] This utility model provides a multi-layer filtration-type wastewater sedimentation reagent mixing device, including: a chamber, a motor fixedly connected to the top of the chamber, and a filter screen detachably disposed above the motor; as well as a quick-change mechanism and a groove assembly. The quick-change mechanism includes a bottom ring fixedly connected to the motor, a rotating ring rotatably connected to the bottom ring, a baffle slidably connected to the rotating ring, and a sliding column fixedly connected to the baffle. The groove assembly includes a rotating groove formed within the bottom ring, a sliding groove formed on the rotating ring, and a limiting groove; the rotating ring is slidably disposed within the rotating groove, the baffle is slidably disposed within the sliding groove, and the sliding column is slidably disposed within the limiting groove. The rotating ring drives the baffle and sliding column to move in their respective grooves, achieving rapid release and fixation of the filter screen.

[0009] Preferably, the quick-change mechanism further includes a mounting base fixedly connected to the motor; the groove assembly also includes threaded grooves and slots formed on the mounting base, which provide a structural basis for the quick installation of the protective component.

[0010] Preferably, the quick-change mechanism further includes a screw and a support; the screw is threaded into a threaded groove, the support is inserted into a slot, and the screw is used to quickly tighten and loosen the support by rotating it to abut or loosen it.

[0011] Preferably, the quick-change mechanism also includes a protective component, which is fixedly connected to the support column. Through the plug-in cooperation between the support column and the fixed seat, the protective component can be stably installed on the outside of the motor and can be quickly disassembled by loosening the screws when needed.

[0016] Preferably, a support leg is fixedly connected to the bottom of the chamber, which provides stable and solid physical support for the entire equipment, ensuring the smooth operation of the equipment.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem that filters are mostly fixed with bolts and the replacement process is cumbersome and time-consuming in the prior art by setting up a quick-change mechanism composed of a bottom ring, a rotating ring, a baffle and corresponding groove components.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Example: Reference Figures 1 to 4 This utility model provides a multi-layer filtration wastewater sedimentation agent mixing device, which aims to solve the structural defects in the prior art that result in low maintenance efficiency due to the cumbersome and time-consuming process of replacing filter screens and disassembling protective parts during equipment maintenance.

[0024] like Figure 1 and Figure 2 As shown, the system includes a chamber 1 and a motor 6 fixedly connected to the inner wall above the chamber 1. The chamber 1 serves as the main housing and reaction space for the entire equipment, handling the mixing and treatment of wastewater and chemicals. The motor 6 provides the power required for the equipment's operation. A filter screen 9 is detachably mounted above the motor 6, used for preliminary filtration of wastewater after it enters the chamber 1, removing impurities and improving the treatment effect.

[0025] The quick-change mechanism 7 is located in the connection area between the motor 6 and the filter 9, enabling convenient installation and removal of the filter 9. The quick-change mechanism 7 includes a bottom ring 71 fixedly connected to the bottom of the motor 6, serving as the basic support component. A rotating ring 72 is rotatably connected to the bottom ring 71; the circumferential movement of the rotating ring 72 is crucial for achieving the quick-change function. The quick-change mechanism 7 also includes a baffle 73 and a sliding column 74 fixedly connected to the baffle 73. The baffle 73 is slidably connected inside the rotating ring 72, and the sliding column 74 further assists in the sliding and positioning of the baffle 73.

[0026] The groove assembly 79 includes a rotating groove 791 formed on the inner wall of the bottom ring 71, with a rotating ring 72 slidably disposed within the rotating groove 791. The rotating groove 791 guides the rotating ring 72 to rotate smoothly in a circumferential direction. The groove assembly 79 also includes a sliding groove 792 and a limiting groove 793 formed on the upper surface of the rotating ring 72. A baffle 73 is slidably disposed within the sliding groove 792, and a sliding column 74 is slidably disposed within the limiting groove 793. When the filter screen 9 needs to be replaced, the rotating ring 72 is manually rotated, causing it to slide in the rotating groove 791, simultaneously driving the baffle 73 and the sliding column 74 to slide within the sliding groove 792 and the limiting groove 793, respectively. This linkage mechanism allows the baffle 73 to detach from its original position where the filter screen 9 is fixed, thus enabling the filter screen 9 to be easily removed and replaced, greatly improving the convenience of maintenance.

[0027] like Figure 1As shown, the quick-change mechanism 7 also includes a mounting base 75 fixedly connected to the motor 6. The groove assembly 79 also includes a threaded groove 794 and a slot 795 formed on the mounting base 75. The mounting base 75 serves as the mounting base for the protective structure of the motor 6, and the threaded groove 794 and slot 795 on it provide a foundation for the connection and positioning of subsequent components. The quick-change mechanism 7 also includes a screw 76 and a support 77. The screw 76 is threaded into the threaded groove 794, and the support 77 is inserted into the slot 795. The screw 76 is used to abut or loosen the support 77, thereby fixing or releasing the support 77. This design allows the support 77 to be pulled directly out of the slot 795 after loosening the screw 76 when disassembly is required. The quick-change mechanism 7 also includes a protective member 78, which is fixedly connected to the support 77. Through the cooperation between the support 77 and the mounting base 75 and the tightening or loosening of the screw 76, the protective member 78 can be quickly installed or removed. This structure greatly simplifies the repair and replacement process of the motor's six protective components, improving the efficiency and convenience of equipment maintenance.

[0028] The groove assembly 79 of the quick-change mechanism 7 also includes a threaded groove 794 and a slot 795 formed on the fixed base 75. The fixed base 75 is fixedly connected to the motor 6, and the threaded groove 794 and slot 795 provided thereon provide a structural basis for the quick installation and removal of the motor protective components.

[0029] The quick-change mechanism 7 also includes a screw 76 and a support column 77. The screw 76 is threaded into a threaded groove 794, and the support column 77 is inserted into a slot 795. By screwing in and out, the screw 76 can directly engage or disengage the support column 77, thus achieving fastening or release of the support column 77 without completely removing the screw 76. The cooperation between the support column 77 and the slot 795 ensures the stability of the protective component during installation and the smoothness of disassembly. The quick-change mechanism 7 also includes a protective component 78. The protective component 78 is fixedly connected to the support column 77. Through the synergistic action of the support column 77, the screw 76, and the fixing seat 75, the protective component 78 can be quickly installed in place to protect the motor, or quickly disassembled for motor maintenance or cleaning. It also includes a dispensing mechanism 8. A medicine inlet 5 is fixedly connected to the outer wall of the chamber 1, and the dispensing mechanism 8 is located at the medicine inlet 5. The feeding mechanism 8 includes a housing 81 and a drive block 82 fixedly connected to the housing 81. The drive block 82 serves as the power source for the feeding mechanism 8. The feeding mechanism 8 also includes a gear 83 and a gear ring 84 meshing with the gear 83. The drive end of the gear 83 is fixedly connected to the drive block 82. When the drive block 82 rotates, it directly drives the gear 83 to rotate. The gear ring 84 rotates in the same direction by meshing with the gear 83, forming a compact transmission chain.

[0030] The feeding mechanism 8 also includes a screw rod 85. The screw rod 85 is fixedly connected to the toothed ring 84 and extends through the inlet 5. When the toothed ring 84 rotates, the fixedly connected screw rod 85 also rotates within the inlet 5, using its spiral structure to push the agent into the chamber 1 at a constant flow rate, thereby achieving precise and quantitative agent dosing. An inlet 3 is fixedly connected to the top of the chamber 1 for the inflow of wastewater; an outlet 4 is fixedly connected to the bottom of the chamber 1 for the discharge of treated wastewater. The positions of the inlet 3 and outlet 4 ensure the smooth operation of the wastewater treatment process. A support leg 2 is fixedly connected to the bottom of the chamber 1. The support leg 2 ensures the stability of the multi-layer filtration wastewater sedimentation agent mixing equipment during operation.

[0031] The implementation principle of this embodiment is as follows: During normal operation, wastewater flows into the chamber 1 from the inlet 3 and undergoes multi-layer filtration, where impurities are retained. The chamber 1 is stably supported by support legs 2. Simultaneously, the reagent enters from the inlet 5. When the drive block 82 of the feeding mechanism 8 is activated, the drive block 82 drives the gear 83 to rotate. The gear 83 meshes with the gear ring 84, causing the gear ring 84 to rotate. Since the screw rod 85 is fixedly connected to the gear ring 84 and passes through the inlet 5, the screw rod 85 rotates accordingly, precisely delivering the reagent into the chamber 1. The motor 6 drives the internal stirring device to thoroughly mix the filtered wastewater and reagent, promoting flocculation reaction. The treated wastewater is discharged from the outlet 4.

[0032] When maintenance or replacement of filter 9 is required, the operator rotates the rotating ring 72. The rotating ring 72 slides in the rotating groove 791 opened in the bottom ring 71. The sliding groove 792 and the limiting groove 793 on the rotating ring 72 move accordingly, so that it slides in connection with the baffle 73. The baffle 73 slides in the sliding groove 792, and the sliding column 74, which is fixedly connected to the baffle 73, slides in the limiting groove 793. This linkage causes the baffle 73 to change from a state of firmly fixing filter 9 to a state of leaving the surface of filter 9 and sliding into the sliding groove 792. At this time, filter 9 can be easily removed and replaced.

[0033] When it is necessary to remove the protective component 78, the operator turns the screw 76. The screw 76 is threaded into the threaded groove 794 of the fixing seat 75. After the screw 76 is turned, it releases the locking position of the support column 77. Since the support column 77 is fixedly connected to the protective component 78, the support column 77 together with the protective component 78 can be removed from the slot 795 of the fixing seat 75, realizing the smooth removal of the protective component 78. This quick replacement and removal mechanism significantly improves the maintenance efficiency and convenience of the equipment.
