A flocculant feeding device for sewage treatment

Abstract

This utility model discloses a flocculant dosing device for wastewater treatment, relating to the field of wastewater treatment technology. The utility model includes a cylinder. By pouring solid flocculant into the interior of a feeding assembly, and then activating a drive assembly to rotate a transmission assembly mounted on its output end, the transmission assembly drives an internally mounted stirring assembly to rotate. This stirring assembly agitates the water inside the cylinder. Simultaneously, the rotation of the transmission assembly causes the feeding assembly mounted on its outer surface to rotate, thus dispensing the flocculant into the water in response to the stirring assembly. This ensures that the feeding assembly slowly and regularly adds solid flocculant into the cylinder and mixes it with the agitated water, allowing for precise control of the solid flocculant dosage and improving the practicality of the wastewater treatment flocculant dosing device.

Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to a flocculant dosing device for wastewater treatment. Background Technology

[0002] Wastewater contains a large number of very small suspended solid particles and colloidal substances. By adding metal salt flocculants to the wastewater, it is hydrolyzed to form a large number of insoluble hydroxide precipitates, which effectively removes the small suspended solids and colloidal substances that are difficult to remove by natural sedimentation, and significantly reduces the turbidity and suspended solids concentration of the effluent.

[0003] In existing technologies, the agent is usually slowly poured into the dosing device manually to prepare the flocculant. This prevents the agent from not dissolving in time due to excessively rapid dosing, which can easily lead to the formation of agglomerated particles and affect the flocculant's effectiveness. However, when putting the agent into the dosing device, the operator needs to shake the hand repeatedly to prepare the agent, and it is impossible to control the dosage, which reduces its practicality. Utility Model Content

[0004] To address the problem that when adding chemicals to the dosing device, workers need to manually shake the device back and forth to prepare the chemicals, and it is impossible to control the dosage, thus reducing its practicality, this utility model proposes a flocculant dosing device for wastewater treatment to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a flocculant dosing device for wastewater treatment, comprising a cylinder:

[0007] The cylinder is equipped with a connecting assembly, a driving assembly, a transmission assembly, a stirring assembly, and a feeding assembly.

[0008] A connecting component, the interior of which is connected to the interior of the cylinder, so that the connecting component can load and unload materials into the interior of the cylinder;

[0009] The drive component has its output end fixedly mounted to one end of the transmission component, so that the drive component drives the transmission component to rotate.

[0010] The stirring assembly is fixedly installed on its outer surface and inside the transmission assembly so that the transmission assembly drives the stirring assembly to stir the medicine when it rotates;

[0011] The feeding assembly is fixedly installed inside the transmission assembly on the outer surface, so that the transmission assembly drives the feeding assembly to feed materials when it rotates.

[0012] Furthermore, the connecting components include an inlet pipe and an outlet pipe, both of which are internally connected to the interior of the cylinder, and both are equipped with solenoid valves.

[0013] Furthermore, the drive assembly includes a mounting bracket, the bottom end of which is fixedly mounted to the top end of the cylinder, and a motor is fixedly mounted on one side of the mounting bracket.

[0014] Furthermore, the transmission assembly includes a support frame, the bottom end of which is fixedly installed to the top end of the cylinder, and a connecting shaft is rotatably installed inside the support frame, one end of which is fixedly installed to the output end of the motor;

[0015] A first bevel gear is fixedly mounted on the outer surface of the connecting shaft, and a second bevel gear is meshed with the surface of the first bevel gear.

[0016] Furthermore, the stirring assembly includes a rotating seat, the bottom end of which is fixedly installed to the top end of the cylinder, a rotating shaft is rotatably connected inside the rotating seat, the outer surface of the rotating shaft is fixedly installed to the inside of the second bevel gear, and a stirring rod is fixedly installed on the outer surface of the rotating shaft.

[0017] Furthermore, the feeding assembly includes a feeding hopper, the bottom end of which is fixedly installed to the top end of the cylinder. A drive shaft is rotatably connected inside the feeding hopper, and a feeding roller is fixedly installed on the outer surface of the drive shaft. A feeding groove is formed on the outer surface of the feeding roller.

[0018] Furthermore, the feeding assembly also includes a drive gear, the interior of which is fixedly installed on the outer surface of the connecting shaft, and a driven gear meshing with the surface of the drive gear, the interior of which is fixedly installed on the outer surface of the transmission shaft.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model involves pouring solid agents into the inside of the feeding assembly, then activating the drive assembly to rotate the transmission assembly installed at the output end. This transmission assembly then drives the internally installed stirring assembly to rotate, thereby agitating the water inside the cylinder. Simultaneously, as the transmission assembly rotates, it drives the feeding assembly installed on the outer surface to rotate as well. This allows the feeding assembly to feed the solid agents into the cylinder slowly and regularly, mixing them with the agitated water inside. This enables precise control of the amount of solid agents added, improving the practicality of this flocculant dosing device for wastewater treatment.

[0021] 2. This utility model involves pouring solid medicine into the hopper. Since the inner wall of the hopper and the outer surface of the feeding roller are rotatably connected, and the outer surface of the feeding roller has a feeding groove, the solid medicine entering the hopper can enter the feeding groove. When the connecting shaft rotates with the motor, it drives the drive gear mounted on the outer surface to rotate. The drive gear then drives the driven gear meshing on the surface to rotate. When the driven gear rotates, it drives the internally mounted transmission shaft to rotate, which in turn drives the feeding roller mounted on the outer surface to rotate. This allows the feeding roller, in conjunction with the feeding groove, to quantitatively feed the solid medicine into the cylinder, thereby improving the stability of the solid medicine feeding process.

[0022] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0032] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0034] Please see Figures 1-6 As shown, this utility model is a flocculant dosing device for sewage treatment, including a cylinder 1:

[0035] The cylinder 1 is respectively equipped with a connecting component 2, a driving component 3, a transmission component 4, a stirring component 5, and a feeding component 6;

[0036] Connecting component 2 is internally connected to the interior of cylinder 1, so that connecting component 2 can load and unload materials into the interior of cylinder 1;

[0037] The output end of the drive component 3 is fixedly installed at one end of the transmission component 4 so that the drive component 3 drives the transmission component 4 to rotate.

[0038] The stirring assembly 5 is fixedly installed on its outer surface and inside the transmission assembly 4 so that the transmission assembly 4 drives the stirring assembly 5 to stir the medicine when it rotates;

[0039] The feeding component 6 is fixedly installed inside the transmission component 4 on the outer surface, so that the transmission component 4 drives the feeding component 6 to feed materials when it rotates.

[0040] In use, by connecting component 2 to an external pipe, an external water source can be added into the interior of cylinder 1 through component 2. The flocculant prepared inside cylinder 1 can also be added to the sewage tank through component 2. Solid agents are poured into the feeding component 6, and then the drive component 3 is activated to drive the transmission component 4 installed at the output end to rotate. This causes the transmission component 4 to drive the internally installed stirring component 5 to rotate, thus agitating the water inside cylinder 1. Simultaneously, when the transmission component 4 rotates, it drives the feeding component 6 installed on the outer surface to rotate, allowing the feeding component 6 to feed the solid agents into the agitated water source by the stirring component 5. This ensures that the feeding component 6 slowly and regularly adds the solid agents into the interior of cylinder 1 and mixes them with the agitated water inside, facilitating the preparation of the flocculant.

[0041] This invention involves pouring solid reagent into the feeding assembly 6, then activating the drive assembly 3 to rotate the transmission assembly 4 installed at the output end. This causes the transmission assembly 4 to rotate the internally installed stirring assembly 5, which in turn agitates the water inside the cylinder 1. Simultaneously, as the transmission assembly 4 rotates, it drives the feeding assembly 6 installed on the outer surface to rotate as well. This allows the feeding assembly 6 to feed the solid reagent into the cylinder 1 slowly and regularly, mixing it with the agitated water inside the cylinder 1. This enables precise control of the amount of solid reagent added, improving the practicality of this flocculant dosing device for wastewater treatment.

[0042] In one embodiment, the connecting component 2 includes an inlet pipe 201 and a outlet pipe 202. The interiors of both the inlet pipe 201 and the outlet pipe 202 are connected to the interior of the cylinder 1. Solenoid valves 203 are installed inside both the inlet pipe 201 and the outlet pipe 202.

[0043] By connecting the inlet pipe 201 to an external water source, when the solenoid valve 203 installed inside the inlet pipe 201 is activated, the external water source can enter the interior of the cylinder 1 through the inlet pipe 201. At the same time, one end of the outlet pipe 202 is connected to an external pump body. After the flocculant inside the cylinder 1 is prepared, the solenoid valve 203 installed inside the outlet pipe 202 is opened, and the pump body is activated to cooperate with the outlet pipe 202 to extract the flocculant inside the cylinder 1 and pump it into the interior of the sewage treatment tank.

[0044] In one embodiment, the drive assembly 3 includes a mounting bracket 301, the bottom end of which is fixedly mounted to the top end of the cylinder 1, and a motor 302 is fixedly mounted on one side of the mounting bracket 301.

[0045] The mounting bracket 301 is designed to support the motor 302 mounted on one side, thereby improving the stability of the motor 302 during operation.

[0046] In one embodiment, the transmission component 4 includes a support frame 401, the bottom end of which is fixedly installed with the top end of the cylinder 1, and a connecting shaft 402 is rotatably provided inside the support frame 401, one end of which is fixedly installed with the output end of the motor 302.

[0047] A first bevel gear 403 is fixedly mounted on the outer surface of the connecting shaft 402, and a second bevel gear 404 is meshed with the surface of the first bevel gear 403.

[0048] The connecting shaft 402 installed at the output end is driven to rotate by starting the motor 302. Since the outer surface of the connecting shaft 402 is rotated with the inside of the support frame 401, and the outer surface of the connecting shaft 402 is fixedly installed with the inside of the first bevel gear 403, when the connecting shaft 402 rotates, it can drive the first bevel gear 403 to rotate with the inside of the support frame 401 as the center. This causes the first bevel gear 403 to drive the second bevel gear 404, which is meshed with the first bevel gear 403, to rotate, thereby improving the stability of the first bevel gear 403 during transmission.

[0049] In one embodiment, the stirring assembly 5 includes a rotating seat 501, the bottom end of which is fixedly installed with the top end of the cylinder 1. A rotating shaft 502 is rotatably connected inside the rotating seat 501. The outer surface of the rotating shaft 502 is fixedly installed with the inside of the second bevel gear 404. A stirring rod 503 is fixedly installed on the outer surface of the rotating shaft 502.

[0050] When the second bevel gear 404 rotates along with the first bevel gear 403, it drives the internally mounted rotating shaft 502 to rotate. Since the outer surface of the rotating shaft 502 is rotatably mounted to the inside of the rotating seat 501, and the outer surface of the rotating shaft 502 is fixedly mounted to the inside of the stirring rod 503, when the rotating shaft 502 rotates, it drives the stirring rod 503 to rotate around the inside of the rotating seat 501 as the center, so that the stirring rod 503 can stir the medicine inside the cylinder 1, thereby improving the mixing efficiency of the medicine.

[0051] In one embodiment, the feeding assembly 6 includes a feeding hopper 601. The bottom end of the feeding hopper 601 is fixedly installed with the top end of the cylinder 1. A drive shaft 602 is rotatably connected inside the feeding hopper 601. A feeding roller 603 is fixedly installed on the outer surface of the drive shaft 602. A feeding groove 604 is opened on the outer surface of the feeding roller 603.

[0052] The feeding assembly 6 also includes a drive gear 605, the interior of which is fixedly installed on the outer surface of the connecting shaft 402, and a driven gear 606 meshing with the surface of the drive gear 605, the interior of which is fixedly installed on the outer surface of the transmission shaft 602.

[0053] By pouring solid medicine into the hopper 601, the solid medicine can enter the hopper 601 and then the hopper 601. Since the inner wall of the hopper 601 is rotatably mounted to the outer surface of the feeding roller 603, and the outer surface of the feeding roller 603 has a feeding groove 604, the solid medicine entering the hopper 601 can enter the feeding groove 604. Therefore, when the connecting shaft 402 rotates with the drive of the motor 302, the connecting shaft 402 drives the drive gear 605 mounted on its outer surface to rotate. This causes the drive gear 605 to drive the driven gear 606, which is meshed with the drive gear 606, to rotate. When the wheel 606 rotates, it drives the internally mounted transmission shaft 602 to rotate, which in turn drives the externally mounted feeding roller 603 to rotate. This allows the feeding roller 603, in conjunction with the feeding trough 604, to feed the solid agent quantitatively into the cylinder 1. Since the driving gear 605 and the driven gear 606 are set with a certain tooth ratio, the driving gear 605 can rotate multiple times to drive the driven gear 606 to rotate one revolution. The tooth ratio between the driving gear 605 and the driven gear 606 can be set according to actual use.

[0054] Through the above technical solution, 1. By pouring solid agent into the inside of the feeding component 6, and then starting the drive component 3 to drive the transmission component 4 installed at the output end to rotate, the transmission component 4 drives the internally installed stirring component 5 to rotate, thereby enabling the stirring component 5 to agitate the water inside the cylinder 1. At the same time, when the transmission component 4 rotates, it can drive the feeding component 6 installed on the outer surface to rotate, thereby enabling the feeding component 6 to feed the water in response to the stirring component 5. This ensures that the feeding component 6 slowly and regularly adds solid agent into the inside of the cylinder 1 and mixes it with the agitated water inside the cylinder 1, thereby enabling precise control of the amount of solid agent added and improving the practicality of the flocculant dosing device for sewage treatment.

[0055] 2. By pouring solid medicine into the hopper 601, the inner wall of the hopper 601 is rotatably mounted to the outer surface of the feeding roller 603, and the outer surface of the feeding roller 603 is provided with a feeding groove 604. The solid medicine entering the hopper 601 can then enter the feeding groove 604. When the connecting shaft 402 rotates with the drive of the motor 302, it drives the drive gear 605 mounted on the outer surface to rotate. The drive gear 605 then drives the driven gear 606, which in turn rotates, driving the transmission shaft 602 mounted inside. This, in turn, drives the feeding roller 603 mounted on the outer surface to rotate, allowing the feeding roller 603, in conjunction with the feeding groove 604, to quantitatively feed the solid medicine into the cylinder 1, thereby improving the stability of the solid medicine feeding process.
