Description

Technical Field

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

[0002] During sludge treatment, sludge particles typically carry an electrical charge in water, creating electrostatic repulsion that keeps them dispersed and difficult to settle naturally. Therefore, flocculants are added to the sedimentation tank containing the sludge using a dosing device. These flocculants neutralize the surface charge of the sludge particles and bind multiple particles together to form larger flocs.

[0003] The dosing device mainly delivers chemicals into the sedimentation tank through pipelines. To prevent sludge from clogging the nozzles on the pipelines, the pipelines and nozzles are usually installed on top of the sludge. However, this method means that the chemicals can only be delivered to the surface of the sludge. For thicker sludge layers, it is difficult for the chemicals to penetrate the entire sludge mass by simply delivering them to the surface. When the chemicals cannot penetrate into the sludge, localized sedimentation will occur. This localized sedimentation may cause uneven accumulation of sludge in the sedimentation tank, affecting the normal operation of the sedimentation facilities. It may also lead to excessive suspended solids in the supernatant, requiring further treatment.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a dosing device for sludge sedimentation tanks to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a dosing device for a sludge sedimentation tank, including a sedimentation tank, a support cylinder fixedly connected to the bottom of the inner wall of the sedimentation tank, a separation component provided on the outside of the support cylinder, a dosing component provided on the top of the support cylinder, a plurality of separation ends of the separation component and dosing ends of the dosing component are provided correspondingly, and a rotating component is provided inside the support cylinder, and the rotating component is poweredly connected to the separation component.

[0008] The rotating component is used to drive the separation component to rotate inside the sedimentation tank so that the separation component can separate the sludge, while the dosing component adds chemicals to the separated sludge.

[0009] Furthermore, the separation assembly includes a rotating ring, which is rotatably connected to the outer surface of the support cylinder. A rotating plate is fixedly connected to the outer surface of the rotating ring, and a conical separation plate is fixedly installed at the bottom of the rotating plate. Multiple conical separation plates are provided at the bottom of the rotating plate. A support groove is provided on the inner wall of the sedimentation tank, and the rotating plate is rotatably connected to the support groove.

[0010] Furthermore, the dosing assembly includes a cartridge, which is disposed on the upper side of the support cylinder. A rotary joint is fixedly installed at the bottom of the cartridge, and a transport pipe is fixedly installed at one end of the rotary joint. A pesticide pump is fixedly installed at the top of the rotating plate. The transport pipe is fixedly installed together with the inlet of the pesticide pump. A main pipe is fixedly installed at the outlet of the pesticide pump. A branch pipe is fixedly connected to the outer surface of the main pipe corresponding to the conical separation plate. A nozzle is fixedly installed at the bottom end of the branch pipe.

[0011] Furthermore, a number of support plates are fitted onto the outer surface of the main pipe. The support plates are fixedly connected to the rotating plate. A spray groove is opened on the top of the rotating plate corresponding to the nozzle, and the nozzle is located inside the spray groove.

[0012] Furthermore, a support frame is fixedly installed on the outer surface of the sedimentation tank, the medicine cartridge is sleeved on the support frame, a stirring motor is fixedly installed on the top of the medicine cartridge, and a dosing pipe is fixedly connected to the outer surface of the medicine cartridge.

[0013] Furthermore, the rotating component has a rotating shaft and a fixed shaft, both of which are rotatably connected to the support cylinder. A drive gear is fixedly connected to the outer surface of the rotating shaft, and a connecting gear is fixedly connected to the outer surface of the fixed shaft. The drive gear and the connecting gear mesh with each other. An internal gear meshes with the outer surface of the connecting gear. The internal gear is fixedly connected to the rotating ring. A drive motor is fixedly installed inside the support cylinder, and the output end of the drive motor is fixedly connected to the rotating shaft.

[0014] Furthermore, a connecting pipe is fixedly connected to the top of the support cylinder, a cover is sleeved on the outer surface of the internal gear and the rotating ring, the cover is fixedly installed on the top of the connecting pipe, a sleeve is fixedly installed on the outer surface of the support cylinder, and the rotating ring is rotatably connected to the sleeve.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model uses a rotating component to drive a separation component to rotate inside the sludge, thereby separating the sludge. At the same time, a dosing component can atomize and inject chemicals into the separated sludge. After the separation component and the dosing component rotate past their positions, the separated sludge comes together again. At this time, the sprayed chemicals can be inside the sludge. In addition, the separation component and the dosing component can continuously rotate inside the sedimentation tank, so that the chemicals can be evenly injected into different depths of the sludge layer. The above-mentioned dosing method avoids the phenomenon of local sedimentation of sludge, thus ensuring the effect of sedimentation treatment when the sludge layer is thick.

[0017] 2. This utility model drives a drive motor, which in turn drives a rotating ring to rotate on the outer surface of the support cylinder via a rotating shaft, a drive gear, a connecting gear, and an internal gear. This causes the sludge layer to temporarily separate under the pressure of the conical separation plates. Simultaneously, nozzles corresponding to several conical separation plates spray chemicals into the separated sludge through spray channels. Since multiple conical separation plates and nozzles are arrayed on the rotating plate, and the rotating plate continuously drives the internal rotation of several conical separation plates, the chemicals sprayed by the nozzles can completely cover the sludge stored in the sedimentation tank. This design allows the chemicals to mix relatively evenly with the sludge stored in the sedimentation tank during the dosing operation.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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.

[0030] 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.

[0031] Please see Figures 1-7 As shown, this utility model is a dosing device for a sludge sedimentation tank, including a sedimentation tank 1. A support cylinder 2 is fixedly connected to the bottom of the inner wall of the sedimentation tank 1. A separation component 3 is provided on the outside of the support cylinder 2. A dosing component 4 is provided on the top of the support cylinder 2. Several separation ends of the separation component 3 and dosing ends of the dosing component 4 are provided corresponding to each other. A rotating component 5 is provided inside the support cylinder 2. The rotating component 5 is poweredly connected to the separation component 3.

[0032] The rotating component 5 is used to drive the separation component 3 to rotate inside the sedimentation tank 1 so that the separation component 3 can separate the sludge, while the dosing component 4 adds chemicals to the separated sludge.

[0033] When settling sludge inside sedimentation tank 1, rotating component 5 drives separation component 3 to rotate inside sedimentation tank 1. The rotating separation component 3 can separate the sludge inside sedimentation tank 1. At this time, dosing component 4 can spray chemicals into the separated sludge.

[0034] The rotating component 5 drives the separating component 3 to rotate inside the sludge, thereby separating the sludge. At the same time, the dosing component 4 can atomize the agent and inject it into the separated sludge. After the separating component 3 and the dosing component 4 rotate past their positions, the separated sludge comes together again. At this time, the sprayed agent can be inside the sludge. In addition, the separating component 3 and the dosing component 4 can continuously rotate inside the sedimentation tank 1, so that the agent can be evenly injected into different depths of the sludge. The above dosing method avoids the phenomenon of local sedimentation of sludge, thus ensuring the effect of sedimentation treatment when the sludge layer is thick.

[0035] In one embodiment, the separation component 3 includes a rotating ring 301, which is rotatably connected to the outer surface of the support cylinder 2. A rotating plate 302 is fixedly connected to the outer surface of the rotating ring 301. A conical separation plate 303 is fixedly installed at the bottom of the rotating plate 302. Multiple conical separation plates 303 are provided at the bottom of the rotating plate 302. A support groove 304 is provided on the inner wall of the sedimentation tank 1. The rotating plate 302 is rotatably connected to the support groove 304.

[0036] By rotating the rotating ring 301, the rotating ring 301 drives several conical separation plates 303 to rotate inside the sludge layer via the rotating plate 302. Because the conical separation plates 303 continuously rotate inside the sludge layer, the sludge layer can temporarily separate under the pressure of the conical separation plates. At this time, the dosing assembly 4 can deliver the reagent into the sludge layer. The shape of the conical separation plates 303 minimizes the resistance they encounter when rotating inside the sludge layer. When the rotating ring 301 drives the rotating plate 302 to rotate, the rotating plate 302 can rotate inside the support groove 304. With the support of the support groove 304, the stability of the rotating plate 302 during rotation is ensured.

[0037] In one embodiment, the dosing assembly 4 includes a cartridge 401, which is disposed on the upper side of the support cylinder 2. A rotary joint 402 is fixedly installed at the bottom of the cartridge 401. A transport pipe 403 is fixedly installed at one end of the rotary joint 402. A pesticide pump 404 is fixedly installed at the top of the rotating plate 302. The transport pipe 403 is fixedly installed together with the inlet of the pesticide pump 404. A main pipe 405 is fixedly installed at the outlet of the pesticide pump 404. A branch pipe 406 is fixedly connected to the outer surface of the main pipe 405 corresponding to the conical separation plate 303. A nozzle 407 is fixedly installed at the bottom end of the branch pipe 406.

[0038] When the rotating plate 302 drives several conical separation plates 303 to rotate, the chemical pump 404, main pipe 405, and branch pipes 406 can rotate together with the rotating plate 302. Simultaneously, the chemical pump 404 draws the chemical from inside the cartridge 401 through the transport pipe 403 and the rotary joint 402. The drawn chemical flows directly into the main pipe 405, where it is diverted and flows into the branch pipes 406. At this point, the nozzle 407 can atomize the chemical from the branch pipes 406 and spray it into the sludge that is being separated by the conical separation plates 303, allowing the chemical to contact sludge at different depths. In this configuration, the rotary joint 402 ensures that the connection between the transport pipe 403 and the cartridge 401 remains normal while the rotating plate 302 drives the chemical pump 404 to rotate.

[0039] In one embodiment, for the main pipe 405, a plurality of support plates 408 are sleeved on the outer surface of the main pipe 405. The support plates 408 are fixedly connected to the rotating plate 302. The top of the rotating plate 302 is provided with a spray groove 409 corresponding to the nozzle 407. The nozzle 407 is located inside the spray groove 409.

[0040] After the sludge is separated by the conical separation plate 303, the nozzle 407 can spray the agent inside the branch pipe 406 into the separated sludge through the spray groove 409. The support plate 408 can support the main pipe 405, so that the main pipe 405 will not shake when the rotating plate 302 drives the main pipe 405 to rotate, thus allowing the main pipe 405 and the branch pipe 406 to better transport the agent.

[0041] In one embodiment, for the sedimentation tank 1, a support frame 410 is fixedly installed on the outer surface of the sedimentation tank 1, the medicine cartridge 401 is sleeved on the support frame 410, a stirring motor 411 is fixedly installed on the top of the medicine cartridge 401, and a dosing pipe 412 is fixedly connected to the outer surface of the medicine cartridge 401.

[0042] The cartridge 401 is suspended above the support cylinder 2 under the support of the support frame 410. This arrangement ensures the stability of the cartridge 401 during use, and the support frame 410 does not interfere with the movement of the continuously rotating main pipe 405. The cartridge 401 is equipped with stirring blades, which are driven by a stirring motor 411, allowing the stirring blades to agitate the medicine inside the cartridge 401. By connecting the dosing pipe 412 to an external pipeline, the operator can deliver the medicine into the cartridge 401 through the external pipeline and the dosing pipe 412.

[0043] In one embodiment, for the aforementioned rotating component 5, the rotating component 5 has a rotating shaft 501 and a fixed shaft 502, both of which are rotatably connected to the support cylinder 2. A drive gear 503 is fixedly connected to the outer surface of the rotating shaft 501, and a connecting gear 504 is fixedly connected to the outer surface of the fixed shaft 502. The drive gear 503 and the connecting gear 504 mesh with each other. An internal gear 505 meshes with the outer surface of the connecting gear 504. The internal gear 505 is fixedly connected to the rotating ring 301. A drive motor 506 is fixedly installed inside the support cylinder 2, and the output end of the drive motor 506 is fixedly connected to the rotating shaft 501.

[0044] By driving the drive motor 506, the drive motor 506 can drive the drive gear 503 to rotate via the rotating shaft 501. The drive gear 503 drives the connecting gear 504 to rotate, and the rotating connecting gear 504 drives the internal gear 505 to rotate, so that the internal gear 505 can drive the rotating ring 301 to rotate on the outer surface of the support cylinder 2.

[0045] In one embodiment, for the support cylinder 2, a connecting pipe 507 is fixedly connected to the top of the support cylinder 2, a cover 508 is sleeved on the outer surface of the internal gear 505 and the rotating ring 301, the cover 508 is fixedly installed on the top of the connecting pipe 507, a sleeve 509 is fixedly installed on the outer surface of the support cylinder 2, and the rotating ring 301 is rotatably connected to the sleeve 509.

[0046] The shielding cover 508 can be installed on the top of the support cylinder 2 via the connecting pipe 507. In this case, the shielding cover 508 can shield the internal gear 505 and a portion of the outer surface of the rotating ring 301. Under the shielding effect of the shielding cover 508, dust will not accumulate on the surfaces of the meshing drive gear 503, connecting gear 504, and internal gear 505. The sleeve 509 can support a portion of the outer surface of the rotating ring 301. The sleeve 509 and the shielding cover 508 work together to support and limit the rotation of the rotating ring 301, thereby improving the stability of the rotating ring 301 during rotation.

[0047] Through the above technical solution, 1. The rotating component 5 drives the separation component 3 to rotate inside the sludge, thereby separating the sludge. At the same time, the dosing component 4 can atomize the agent and inject it into the separated sludge. After the separation component 3 and the dosing component 4 rotate past this position, the separated sludge comes together again. At this time, the sprayed agent can be inside the sludge. In addition, the separation component 3 and the dosing component 4 can continuously rotate inside the sedimentation tank 1, so that the agent can be evenly injected into different depths of the sludge. The above dosing method avoids the phenomenon of local sedimentation of sludge, thus ensuring the effect of sedimentation treatment when the sludge layer is thick; 2. By driving the drive motor 506, the drive motor 506 drives the rotating shaft 501 and the drive gear 503. The connecting gear 504 and the internal gear 505 drive the rotating ring 301 to rotate on the outer surface of the support cylinder 2, so that the sludge layer can be temporarily separated under the pressure of the conical separation plate 303. At the same time, the nozzles 407, which correspond one-to-one with the conical separation plates 303, can spray the agent into the separated sludge through the spray groove 409. Since there are multiple conical separation plates 303 and nozzles 407 arranged in an array on the rotating plate 302, and the rotating plate 302 continuously drives the conical separation plates 303 and nozzles 407 to rotate inside the sludge layer, the conical separation plates 303 and nozzles 407 can completely cover the sludge stored in the sedimentation tank 1. This arrangement allows the agent to be mixed more evenly with the sludge stored in the sedimentation tank 1 during the dosing operation.
