Detailed implementation manners

[0042] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0043] As Figures 1 - 12 shown, a chemical addition auxiliary device applicable to a township sewage treatment plant includes a support frame, on which a feed hopper 4, a mixing pipe 3 and a stirring tank 1 that are connected in sequence from top to bottom are installed, and the bottom end of the stirring tank 1 is connected with a discharge pipe 2;

[0044] At least one set of bearing components is also installed on the support frame;

[0045] The bearing component includes a weighing seat 6 with a weighing device, a bearing frame 7 with a bearing through port 28 at the inner end, and an encapsulation block 8 whose outer end face can close the bearing through port 28. The outer end face of the encapsulation block 8 is arranged in an arc shape. A material groove notch 9 that can communicate with the input end of the feed hopper 4 is opened at the top end of the encapsulation block 8. Connecting brackets 11 are connected to both the front and rear sides of the bearing frame 7, and the ends of the connecting brackets 11 are hinged to the outer surface of the feed hopper 4;

[0046] The bearing component further includes a feeding drive assembly, and the feeding drive assembly acts on the bearing frame 7 to enable the bearing frame 7 to rotate around the end of the connecting bracket 11 as the axis and along the outer end face of the encapsulation block 8 until the bearing through port 28 communicates with the material groove notch 9.

[0047] It should be noted that the outer side mentioned in this embodiment refers to the side far from the feed hopper 4; the inner side refers to the side close to the feed hopper 4.

[0048] In this embodiment, through the setting of the connecting bracket 11, there is actually an active connection relationship between the bearing frame 7 and the encapsulation block 8. To achieve the hinge connection between the end of the connecting bracket 11 and the feed hopper 4, a hinge pin 36 that can be rotatably connected to the feed hopper 4 can be provided at the inner end of the end of the connecting bracket 11.

[0049] During application, first, the position of the bearing frame 7 is adjusted through the feeding drive assembly so that it is in a state of being placed on the weighing seat 6. The medicament is first put into the bearing frame 7. The weighing seat 6 can detect the weight of the put medicament. When the appropriate feeding amount is reached, then start the feeding drive assembly to drive the bearing frame 7 to rotate along the outer end face of the encapsulation block 8 until the bearing through-port 28 is communicated with the trough notch 9. At this time, the medicament in the bearing frame 7 will be introduced into the feed hopper 4. During the rotation of the bearing frame 7, due to the setting of the connecting bracket 11, the outer end face of the encapsulation block 8 is always in a state of sealing the bearing through-port 28 until the bearing through-port 28 moves to be directly opposite the trough notch 9, and then the encapsulation block 8 releases the aforementioned sealing state.

[0050] After the medicament in the bearing frame 7 is completely put in, then reset the feeding drive assembly, and the bearing frame 7 can gradually reset to the weighing seat 6 under its own weight.

[0051] To achieve the communication between the trough notch 9 and the input end of the feed hopper 4, preferably, a feed through-port 10 that can be communicated with the trough notch 9 is provided on the side wall of the input end of the feed hopper 4.

[0052] To further improve the stability of the active connection between the bearing frame 7 and the encapsulation block, guide rails 32 can be provided on the outer end face of the encapsulation block 8, and sliding grooves 33 that can be slidably matched with the guide rails 32 are provided on the inner end face of the bearing frame 7.

[0053] As another preferred method, two limiting edges 37 can also be provided on the outer end face of the encapsulation block 8. The bearing frame 7 is located in the area between the two limiting edges 37. Limiting sliding grooves 38 are provided on the limiting edges 37, and limiting protrusions (not shown in the figure) that can cooperate with the limiting sliding grooves 38 are provided on the bearing frame 7.

[0054] To achieve the active sealed connection between the encapsulation block 8 and the bearing frame 7, an elastic layer can be provided on the outer end face of the encapsulation block 8 or the inner end face of the bearing frame 7. The elastic layer can be made of materials such as silica gel and rubber.

[0055] In practice, the medicament may be in a liquid state, or may be in a fixed state such as granular, flaky, or powdery. The bearing assembly described in this embodiment can put and weigh liquid medicaments, but is more suitable for solid medicaments. The liquid medicaments can be weighed separately and externally connected to a hose or introduced into the feed hopper 4 through other containers through the trough notch 9.

[0056] When there are many types of solid medicaments to be dispensed, each type of solid medicament can be weighed one by one through the carrier frame 7. After being dispensed into the feed hopper 4 one by one, they are then uniformly conveyed into the mixing pipe 3 and the mixing tank 1 for mixing and stirring, and then output from the discharge pipe 2. The discharge pipe 2 can be externally connected to a hose for output.

[0057] Preferably, two sets of loading components can also be provided, and the two sets of loading components are respectively connected to both sides of the feed hopper 4. The two sets of loading components can be started synchronously to weigh and dispense appropriate amounts of different types of solid medicaments.

[0058] To realize the driving of the loading driving component for the rotation of the carrier frame 7, preferably, the support frame includes a support plate 22;

[0059] The loading driving component includes two loading driving devices 12 respectively located on the front and rear sides of the feed hopper 4. The output end of the loading driving device 12 is connected with a linkage frame 13, and the loading driving device 12 can act on the linkage frame 13 to move up and down relative to the feed hopper 4;

[0060] The linkage frame 13 has two linkage blocking sections 29 arranged at intervals, and a linkage relief groove 30 is formed between the two linkage blocking sections 29;

[0061] The two connecting brackets 11 respectively pass through the two linkage relief grooves 30.

[0062] In this embodiment, the loading driving device 12 can be selected as an electric push rod. During application, when the loading driving device 12 is started to move the linkage frame 13 upward, the connecting bracket 11 will move upward. Under the hinge action of the connecting bracket 11, the carrier frame 7 will rotate around the hinge point of the connecting bracket 11 as the axis. During the movement, the connecting bracket 11 will also slide relative to the linkage relief groove 30 to compensate for the positional relationship of the rotation angle. After the medicament in the carrier frame 7 is dispensed, the loading driving device 12 is used to move the linkage frame 13 downward, and the carrier frame 7 that loses the support of the linkage frame 13 will reset to the weighing seat 6 under its own weight.

[0063] Preferably, in the same linkage frame 13, a downward pulling elastic member 34 is sleeved on the tops of the two linkage blocking sections 29.

[0064] As Figures 10 - 11 shown, the downward pulling elastic member 34 can be selected as an elastic rope sleeved on the two linkage blocking sections 29. To prevent the elastic rope from moving accidentally, limiting grooves 35 for limiting the downward pulling elastic member 34 can be provided on the surfaces of the two linkage blocking sections 29.

[0065] During application, the carrier frame 7 can be made of a lightweight material. When the loading driving device 12 moves the linkage frame 13 downward, the downward pulling elastic member 34 can gradually pull the carrier frame 7 until it resets to the weighing seat 6.

[0066] As Figure 12 shown, an elastic block 39 can also be connected between the top ends of the two interlocking blocking sections 29.

[0067] Preferably, the bearing assembly further includes a limiting plate 23 connected to the feeding hopper 4. The limiting plate 23 is inclined, and its height gradually increases from the inside to the outside;

[0068] The bottom end of the limiting plate 23 is connected with a pressing plate 24 through a plurality of reset elastic members 25.

[0069] In this embodiment, the pressing plate 24 has two functions. One is: it can limit the extreme position of the rotation of the bearing frame 7 to prevent it from rotating excessively and spilling out the medicament; the other is: when the bearing frame 7 needs to be reset to the weighing seat 6, the feeding driving device 12 can appropriately lift the linkage frame 13 to lift the bearing frame 7 until the pressing plate 24 compresses the reset elastic member 25, and then lower the linkage frame 13. During the reset process of the reset elastic member 25, an elastic force for downward rotation will be given to the bearing frame 7, and then the bearing frame 7 can be reset under its own weight.

[0070] Preferably, a feeding pipe 31 is communicated with the feeding hopper 4 or the stirring tank 1.

[0071] In this embodiment, the feeding pipe 31 is used to put the liquid medicament. When the feeding pipe 31 is arranged on the feeding hopper 4, the liquid medicament can wash the solid medicament from top to bottom, reducing the residue of the solid medicament during the conveying process; when the feeding pipe 31 is arranged on the stirring tank 1, the liquid medicament can directly participate in the mixing effect and reduce the loss of the liquid medicament.

[0072] Preferably, the top end of the feeding hopper 4 has a cover plate 14;

[0073] A mixing driving device 18 is installed on the cover plate 14. The output end of the mixing driving device 18 is connected with a rotating shaft 15 passing through the cover plate 14. The bottom end of the rotating shaft 15 sequentially passes through the feeding hopper 4, the mixing pipe 3 and is located in the stirring tank 1;

[0074] A spiral blade 16 located in the mixing pipe 3 is connected to the rotating shaft 15;

[0075] A plurality of stirring rods 17 located in the stirring tank 1 are also connected to the rotating shaft 15.

[0076] In this embodiment, the mixing driving device 18 is a motor.

[0077] When in use, the spiral blade 16 is equivalent to a dragon. When the mixing drive device 18 is started, the solid medicine put into the feed hopper 4 can be transported to the mixing tank 1. During the transportation process, the spiral blade 16 can prolong the mixing time of the solid medicine, and then the liquid medicine is added. Through the action of the stirring rod 17, multiple medicines can be fully stirred and mixed, and then discharged from the discharge pipe 2.

[0078] In order to achieve sufficient and uniform mixing, a solenoid valve may be provided at the discharge pipe 2, and the mixture is discharged into the sewage treatment pool after being mixed for a specific time.

[0079] In order to improve the stability of the rotation of the rotating shaft 15, preferably, the bottom end of the rotating shaft 15 is connected to a limit ring 26 through a bearing, and the outer ring surface of the limit ring 26 is equipped with a plurality of limit posts 27 connected to the inner wall of the mixing tank 1. Similarly, the top end of the rotating shaft 15 can also be rotatably connected to the cover plate 14 through a bearing. In this way, the rotating shaft 15 can be prevented from accidentally shaking or trembling.

[0080] In order to ensure the stability of the operation of each functional structure of this embodiment, preferably, the support frame includes a mounting ring 19 connected to the mixing tank 1 and a plurality of supporting feet 20 for supporting the mounting ring 19;

[0081] The support frame also includes two support plates 5 for supporting two groups of bearing components respectively;

[0082] The mounting ring 19 is provided with a plurality of supporting legs 21 for supporting the supporting plate 5 .

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
