Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a biological pool sludge scum crushing device. Background Art

[0002] Activated sludge biological method is a common method for sewage treatment, among which parameters such as sludge concentration, sludge age, and residual sludge discharge are important indicators for activated sludge control. In actual operation, due to the ever-changing water quality of sewage, biological pools often maintain high sludge concentrations and long sludge ages, and mechanical stirring or aeration is performed at the same time. After metabolism, some of the microorganisms in the activated sludge will eventually age and die, and too long a sludge age will cause a large amount of dead sludge to be unable to be discharged in time.

[0003] The microorganisms in the activated sludge are aggregated together by the colloids, filamentous bacteria, extracellular polysaccharides and other substances in the flocs. When the activated sludge ages, the microbial clusters in these flocs will break away to form free granular and flake-like activated sludge. This part of the activated sludge has poor coagulation properties and is small and light in weight. During the flow process, it is disturbed by the water flow and floats to the surface to form clumps of sludge. It combines with the fine floating scum that could not be removed by the front-end pretreatment and even aggregates to form large floating objects. Under the action of stirring and gas, it accumulates more and more on the water surface of the pool, which not only affects the treatment effect of the biological pool, but also affects the cleanliness and appearance of the pool surface.

[0004] Especially during the winter in northern regions, sewage treatment plants with lower water temperatures often maintain a high sludge concentration to ensure that treated water quality meets standards, which can easily cause sludge aging and induce sludge expansion and floating of filamentous and non-filamentous bacteria, sludge foam and other problems. In winter, these foam scums accumulate on the surface of the biological pool and even freeze into lumps, which are difficult to remove and may even cover the entire pool surface.

[0005] Usually, the above problems are dealt with by manual salvage. However, manual salvage has the problems of high labor intensity, low efficiency, and potential safety hazards. The salvage boats commonly used for river cleaning are difficult to move flexibly in sewage treatment plants due to the pool area and structure, and are not very applicable. Therefore, it is necessary to design a scum removal device for sewage treatment biological pools to break it up so that it can follow the water flow and smoothly enter the subsequent secondary sedimentation tank treatment unit, and be removed by the scraper through mud and water separation.

In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the utility model and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-6 , the preferred embodiments of the utility model are further described in detail:

[0026] like Figure 1-6As shown, the utility model is preferably a biological pond sludge scum crushing device, including a device body and a remote controller 1, the device body includes a pontoon base 2, the pontoon base 2 is provided with a control unit 3, a power supply assembly 4, a propulsion assembly 5 and a crushing assembly 6, the control unit 3 is connected to the propulsion assembly 5 through a cable for transmitting control signals, the power supply assembly 4 is connected to the control unit 3 and the propulsion assembly 5 through a cable, and is used to provide power for the operation of the control unit 3 and the propulsion assembly 5, the propulsion assembly 5 is used to drive the device body to realize straight travel, left turn and right turn functions on the water surface, the crushing assembly 6 is arranged in a circular array on the side of the pontoon base 2, and is used to crush and disperse the sludge scum on the water surface, and a protective shell 7 is also provided on the top of the pontoon base 2, the protective shell 7 and the pontoon base 2 are enclosed to form a closed space for protecting the components arranged above the pontoon base 2, the remote controller 1 is used to control the operation of the device body, and the remote controller 1 and the control unit 3 realize signal transmission by wireless transmission;

[0027] The crushing assembly 6 can be configured as a plurality of groups of crushing tooth rakes 608 arranged in a circular array on the sides of the pontoon base 2. The crushing tooth rakes 608 can be in the form of a single rake tooth structure or in the form of a plurality of rake teeth welded together;

[0028] Although the structure of directly fixing the crushing tooth rake 608 on the pontoon base 2 is simple, the pontoon base 2 of this structural form needs to be provided with a larger horizontal cross-sectional size to avoid the overturning problem, and the protruding crushing tooth rake 608 is not convenient for on-site operators to carry;

[0029] To this end, the structural form of the crushing assembly 6 can be optimized. At this time, the crushing assembly 6 includes a plurality of crushing buoys 607, which are arranged in a circular array on the sides of the pontoon base 2. The crushing buoys 607 are hollow structures, the lower part of the sphere is submerged in water, and the upper part of the sphere floats on the water surface. The inner end of the sphere is connected to the pontoon base 2 through a transmission secondary shaft 606, and a crushing tooth rake 608 is fixed to the outer end of the sphere near the waterline. The crushing tooth rake 608 can be a single rake tooth structure or a structure in which multiple rake teeth are welded together. The outwardly extended crushing buoys 607 can effectively increase the coverage area on the water surface and increase the anti-overturning ability of the device body. At the same time, it is also convenient to replace crushing buoys 607 of different sizes according to the self-weighting condition of the device body. The sides of the pontoon base 2 are smoother and convenient to carry, and the operator will not be scratched or stabbed by the crushing tooth rake 608 when carrying the machine body.

[0030] Under normal circumstances, the scum can be cut and separated only by the cutting force generated by the crushing tooth rake 608 as the device body moves. However, for agglomerated scum, the cutting and crushing effect of the cutting force generated by the crushing tooth rake 608 as the device body moves will be poor. Therefore, the crushing assembly 6 can be further optimized. Figure 6 As shown, the crushing assembly 6 also includes a crushing motor 601, a gear box 602, a driving main shaft 603, a main bevel gear 604 and a secondary bevel gear 605. The crushing motor 601 is connected to the control unit 3 and the power supply assembly 4 through a cable. The driving main shaft 603 is installed on the gear box 602 through a bearing. One end of the driving main shaft 603 extends out of the gear box 602 to connect with the crushing motor 601. The main bevel gear 604 is fixedly sleeved on the driving main shaft 603 in the gear box 602, and a plurality of secondary bevel gears 605 are meshed on the main bevel gear 604. The secondary bevel gear 605 is fixedly sleeved. It is arranged on the transmission secondary shaft 606, which is installed on the gear box 602 through a bearing and is perpendicular to the driving main shaft 603. One end of the transmission secondary shaft 606 extends out of the gear box 602 and is connected to the crushing float 607. The transmission secondary shaft 606 is installed on the buoy base 2 through a bearing. The crushing motor 601 can drive each transmission secondary shaft 606 to rotate at a certain speed through the cooperation of the gear box 602, the driving main shaft 603, the main bevel gear 604 and the secondary bevel gear 605, and then drive the crushing tooth rake 608 through the crushing float 607 to cut and separate the agglomerated slag.

[0031] The propulsion assembly 5 can adopt a structure of a left-drive motor and a right-drive motor, which are installed at the waterline position of the pontoon base 2, one on the left and one on the right, and propellers 503 are installed at the ends of the output shafts of the left-drive motor and the right-drive motor. The control unit 3 controls the straight-moving, left-turning and right-turning functions of the device body by controlling the working states of the left-drive motor and the right-drive motor.

[0032] Of course, in order to avoid the problem that the propulsion assembly 5 of the structural form of the left drive motor and the right drive motor has a high requirement for the draft depth, and to avoid the influence of the surface scum on the normal operation of the left drive motor and the right drive motor, the propulsion assembly 5 can also adopt the structural form of a pod propeller, such as Figure 5As shown, the pod-type propulsion device is suspended below the pontoon base 2 and submerged in the water, and is used to drive the device body to realize the functions of straight travel, left turn and right turn on the water surface. Specifically, the following structural form can be adopted. The pod-type propulsion device includes a pod body 501, a boom 502, a propeller 503, a propulsion motor 504, a main steering gear 505, a secondary steering gear 506 and a steering motor 507.

The bottom end of the boom 502 is fixed on the pod body 501, and a propulsion motor 504 is installed in the pod body 501. The output end of the propulsion motor 504 is installed with a propeller 503. The boom 502 is a hollow tube, and the transmission and control cables required by the propulsion motor 504 are arranged in the tube cavity. The propulsion motor 504 drives the propeller 503 to rotate to provide propulsion power. In order to realize the steering function, a secondary steering gear 506 is fixedly sleeved on the top of the boom 502, and a steering motor 507 is installed on the buoyancy tank base 2 on one side of the boom 502. A main steering gear 505 is installed on the output end of the steering motor 507, and the main steering gear 505 is meshed and connected with the secondary steering gear 506. The steering motor 507 drives the boom 502 to rotate through the meshed main steering gear 505 and the secondary steering gear 506, thereby realizing the change of the direction of the cabin 501, thereby realizing the left and right turn functions of the device body;

[0033] The power supply assembly 4 can directly adopt the structural form of the battery 401. Considering the green energy-saving and environmental protection requirements, the power supply assembly 4 can also include a photovoltaic panel 402. The battery 401 is arranged in a closed space formed by the protective shell 7 and the pontoon base 2. The photovoltaic panel 402 is electrically connected to the battery 401 through a cable, and the photovoltaic panel 402 is arranged on the top of the protective shell 7 as the top cover of the protective shell 7. The photovoltaic panel 402 converts solar energy into electrical energy and stores it in the battery 401. The output end of the battery 401 is connected to the input end of the DC / DC converter.
