Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device with high efficiency in sludge removal. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. This includes separating sludge and water through steps such as sedimentation and oxidation, purifying the water for secondary use, and drying and reusing the sludge.

[0003] A search revealed a patent document with publication number "CN220589033U" that discloses a high-efficiency sludge removal device for wastewater treatment. The device includes a wastewater sedimentation tank with inclined surfaces on all four sides at the bottom and a sludge removal trough. A sludge removal auger driven by a geared motor is installed inside the sludge removal trough. A sludge removal outlet is located at one end of the trough, and an electric shut-off valve is installed at the outlet pipe. The upper part of the sedimentation tank has a wastewater inlet and a drainage outlet. The wastewater inlet is connected to a wastewater pump via a pipe, and the drainage outlet is connected to a self-priming drainage pump via a pipe. A float-type suction port is connected to the inside of the drainage outlet via a flexible pipe. A flow sensor is installed on the outlet pipe of the self-priming drainage pump. The wastewater pump, self-priming drainage pump, geared motor, electric shut-off valve, and flow sensor are all electrically connected to a controller. This high-efficiency sludge removal device for wastewater treatment can automatically empty clarified water and automatically remove sludge, exhibiting high automation and high sludge removal efficiency.

[0004] Based on the above search and combined with existing technology, it was found that existing high-efficiency sludge discharge wastewater treatment devices set the bottom of the sedimentation tank into a funnel-shaped channel that gradually narrows from top to bottom in order to concentrate the settled sludge into the sludge discharge tank. However, since sludge generally has strong adhesion, some sludge will adhere to the inner wall of the channel during discharge, making it difficult to discharge smoothly and causing inconvenience to the sludge discharge operation. Therefore, there is a need for a wastewater treatment device with high-efficiency sludge discharge. Utility Model Content

[0005] The purpose of this application is to provide a wastewater treatment device with high efficiency in sludge discharge, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a wastewater treatment device for efficient sludge discharge, comprising a fixedly installed sedimentation tank and a forced sludge discharge pipe, a centralized sludge hopper between the sedimentation tank and the forced sludge discharge pipe, a sludge discharge pipe fixedly connected to the lower end of the forced sludge discharge pipe, a sludge discharge auger rotatably connected inside the forced sludge discharge pipe, and a drive motor for driving the sludge discharge auger to rotate fixedly installed on one side of the forced sludge discharge pipe.

[0007] Both ends of the centralized sludge hopper are connected to elastic connectors. The upper and lower ends of the centralized sludge hopper are elastically connected to the sedimentation tank and the forced sludge discharge pipe through two elastic connectors respectively. Elastic support components are installed on the outside of the centralized sludge hopper to elastically support the centralized sludge hopper.

[0008] A vibration generating mechanism is also installed on one side of the centralized sludge discharge hopper. The vibration generating mechanism generates vibration when sludge is discharged, and drives the centralized sludge discharge hopper to vibrate synchronously.

[0009] Preferably, the elastic connector includes a flexible connecting ring and a flexible connecting pipe. The flexible connecting ring is located between the upper end of the centralized sludge hopper and the sedimentation tank, and is fixed to the bottom of the sedimentation tank and the top of the centralized sludge hopper at its upper and lower ends, respectively.

[0010] Preferably, the elastic support includes an elastic damping support column, one end of which is rotatably connected to the outer wall of the centralized sludge hopper via a spherical universal connector, and the other end of which is rotatably connected to the surrounding foundation via a universal spherical support.

[0011] Preferably, the vibration generating mechanism includes a vibration motor, which is fixed to the outer wall of the centralized sludge hopper.

[0012] Preferably, the vibration generating mechanism includes a protruding post, a cylindrical cam, and a transmission component. The protruding post is fixed to one side of the outer wall of the centralized sludge hopper. The driving surface of the cylindrical cam slides against one end of the protruding post.

[0015] 1. In this utility model, by setting up a vibration generating mechanism, the vibration generating mechanism can drive the centralized sludge hopper to vibrate.

[0016] 2. In this utility model, the flexible connecting ring and flexible connecting pipe can meet the needs of the centralized sludge hopper to connect with the sedimentation tank and the forced sludge discharge pipe. At the same time, the elastic damping support column can provide reliable support for the centralized sludge hopper and allow the centralized sludge hopper to vibrate freely, thereby meeting the vibration requirements of the centralized sludge hopper and facilitating the improvement of sludge discharge efficiency and effect.

[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 1:

[0024] refer to Figures 1-2The wastewater treatment device for efficient sludge discharge shown includes a fixed sedimentation tank 1 and a forced sludge discharge pipe 3. The sedimentation tank 1 and the forced sludge discharge pipe 3 can be fixed to the ground by a bracket or directly fixed in the foundation. A centralized sludge hopper 2 is provided between the sedimentation tank 1 and the forced sludge discharge pipe 3. The lower end of the forced sludge discharge pipe 3 is fixed and connected to a sludge discharge pipe 4. A sludge discharge auger 6 is rotatably connected inside the forced sludge discharge pipe 3. A drive motor 5 for driving the sludge discharge auger 6 to rotate is fixedly installed on one side of the forced sludge discharge pipe 3.

[0025] Both ends of the centralized sludge hopper 2 are connected to elastic connectors. The upper and lower ends of the centralized sludge hopper 2 are elastically connected and communicated with the sedimentation tank 1 and the forced sludge discharge pipe 3 through two elastic connectors. Specifically, the elastic connectors include a flexible connecting ring 7 and a flexible connecting pipe 8. Both the flexible connecting ring 7 and the flexible connecting pipe 8 are flexible connecting rings (or pipes) with a certain degree of elasticity, such as metal corrugated pipes, cast iron flexible drainage pipes, etc., so as to achieve a stable and flexible connection between the centralized sludge hopper 2 and the sedimentation tank 1 and the forced sludge discharge pipe 3. The flexible connecting ring 7 is located between the upper end of the centralized sludge hopper 2 and the sedimentation tank 1. The upper and lower ends of the flexible connecting ring 7 are fixed to the bottom of the sedimentation tank 1 and the top of the centralized sludge hopper 2, respectively. The flexible connecting pipe 8 is located between the lower end of the centralized sludge hopper 2 and the upper end of the forced sludge discharge pipe 3. The upper and lower ends of the flexible connecting pipe 8 are fixed to the bottom of the centralized sludge hopper 2 and the top of the forced sludge discharge pipe 3, respectively. The flexible connecting ring 7 and the flexible connecting pipe 8 are fixed and sealed to the sedimentation tank 1, the centralized sludge hopper 2, and the forced sludge discharge pipe 3 through flanges 11.

[0026] An elastic support is installed on the outside of the centralized sludge hopper 2. The elastic support is used to elastically support the centralized sludge hopper 2. Specifically, the elastic support includes an elastic damping support column 10 (the elastic damping support column 10 is composed of a damping support rod / damper and a return spring, which can realize elastic damping support for the centralized sludge hopper 2). One end of the elastic damping support column 10 is rotatably connected to the outer wall of the centralized sludge hopper 2 through a spherical universal connector (the spherical universal connector is existing technology, and universal ball joint connectors, universal ball joint rods, etc. can be used. The specific structure and working principle are well known to those skilled in the art and will not be described in detail here). The other end of the elastic damping support column 10 is rotatably connected to the surrounding foundation (or fixed support, fixed base, etc.) through a universal spherical support (the universal spherical support is also existing technology, and universal anti-pull-out spherical support can be used. The specific structure and working principle are well known to those skilled in the art and will not be described in detail here).

[0027] A vibration generating mechanism is also installed on one side of the centralized sludge discharge hopper 2. The vibration generating mechanism generates vibration when discharging sludge and drives the centralized sludge discharge hopper 2 to vibrate synchronously. The vibration generating mechanism includes a vibration motor 9 (the vibration motor 9 is existing technology, and those skilled in the art can further select the appropriate motor model according to the usage requirements, which will not be described in detail here). The vibration motor 9 is fixed to the outer wall of the centralized sludge discharge hopper 2.

[0028] Based on the above structure, when the drive motor 5 starts, the vibration motor 9 starts synchronously. The drive motor 5 drives the sludge discharge auger 6 to rotate, thereby forcibly discharging the sludge concentrated in the forced sludge discharge pipe 3 to achieve a good sludge discharge effect. At the same time, the vibration motor 9 drives the centralized sludge hopper 2 to vibrate. When the centralized sludge hopper 2 vibrates, the sludge gathered in the centralized sludge hopper 2 is affected by the vibration and sinks quickly, thereby reducing the probability of sludge adhering to the inner wall of the centralized sludge hopper 2, further enhancing the sludge discharge effect of the sewage treatment device, and also accelerating the sludge discharge speed and improving the sludge discharge efficiency.

[0029] The flexible connecting ring 7 and the flexible connecting pipe 8 can meet the needs of the centralized sludge hopper 2 to connect with the sedimentation tank 1 and the forced sludge discharge pipe 3. At the same time, the elastic damping support column 10 can provide reliable support for the centralized sludge hopper 2 and allow the centralized sludge hopper 2 to vibrate freely, thereby meeting the vibration requirements of the centralized sludge hopper 2 and facilitating the improvement of sludge discharge efficiency and effect.

[0030] Example 2:

[0031] refer to Figure 3 The wastewater treatment device shown is a high-efficiency sludge removal device, which is based on Example 1, but differs from Example 1 in that:

[0032] The vibration generating mechanism includes a protruding post 12, a cylindrical cam 13 and a transmission component. The protruding post 12 is fixed to one side of the outer wall of the centralized sludge hopper 2. The driving surface of the cylindrical cam 13 slides against one end of the protruding post 12. The cylindrical cam 13 is rotatably connected to the surrounding foundation through a rotating shaft. The output shaft of the drive motor 5 drives the cylindrical cam 13 to rotate through the transmission component.

[0033] Specifically, the transmission component includes a transmission sprocket assembly 14, which includes two sprockets and a chain meshing with the two sprockets. The two sprockets of the transmission sprocket assembly 14 are respectively fixedly sleeved on the output shaft of the drive motor 5 and the rotating shaft of the cylindrical cam 13.

[0034] By setting up the convex post 12, the cylindrical cam 13, and the transmission sprocket set 14, when the drive motor 5 is started, the output shaft of the drive motor 5 not only drives the sludge discharge auger 6 to rotate, but also drives the cylindrical cam 13 to rotate through the transmission sprocket set 14. When the cylindrical cam 13 rotates, it drives the convex post 12 to slide back and forth. When the convex post 12 slides back and forth, it causes the concentrated sludge hopper 2 to move back and forth, thereby realizing the effect of using the power of the drive motor 5 to drive the concentrated sludge hopper 2 to generate reciprocating vibration. Compared with directly setting the vibration motor 9, it can save equipment costs and save energy.

[0035] The working principle of this utility model is as follows: During daily use, when the drive motor 5 starts, the vibration generating mechanism starts synchronously. The drive motor 5 drives the sludge discharge auger 6 to rotate, thereby forcibly discharging the sludge concentrated in the forced sludge discharge pipe 3 to achieve a good sludge discharge effect. At the same time, the vibration generating mechanism drives the centralized sludge hopper 2 to vibrate. When the centralized sludge hopper 2 vibrates, the sludge gathered in the centralized sludge hopper 2 is affected by the vibration and sinks quickly, thereby reducing the probability of sludge adhering to the inner wall of the centralized sludge hopper 2, further enhancing the sludge discharge effect of the sewage treatment device, and also accelerating the sludge discharge speed and improving the sludge discharge efficiency.

[0036] It should be further noted that the technical features involved in this utility model patent application, such as the drive motor, mud discharge auger, vibration motor, elastic damping support column, cylindrical cam, and transmission sprocket assembly, should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
