Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a building wastewater treatment device. Background Technology

[0002] Construction wastewater treatment equipment is suitable for various construction site scenarios, such as high-rise residential buildings, commercial complexes, municipal road and bridge construction areas, and industrial plant expansion projects. It can treat different types of wastewater, such as concrete mixing wastewater, foundation pit excavation mud water, and construction vehicle washing wastewater. It can also be applied to old city renovation and demolition areas to treat wastewater generated during construction waste transportation, ensuring that the drainage of the construction area meets the standards, avoiding direct discharge of sewage into surrounding rivers, soil and groundwater resources, and meeting the requirements of green construction and environmental protection.

[0003] According to the publicly available announcement (CN220201496U), a construction wastewater treatment device is disclosed. This technology discloses a design including a support plate, a support bracket fixedly connected to the left side of the upper part of the support plate (the upper end of the support bracket is annular), an inlet chamber fixedly connected to the upper end of the support bracket (the lower end of the inlet chamber is cylindrical), a support rod fixedly connected to the left side of the upper part of the support plate, a solid-liquid separation device at the upper end of the support rod, a liquid purification device in the middle of the upper part of the support plate, and a solid collection box on the right side of the upper part of the support plate. This invention achieves the technical effects of separating solids and wastewater from construction wastewater through the solid-liquid separation device for separate treatment, and fully mixing wastewater with chemicals through the liquid purification device for purification, thereby improving the treatment efficiency of construction wastewater.

[0004] However, existing technologies still have the following problems:

[0005] In existing building wastewater treatment technologies, single-stage or simple sedimentation devices still suffer from the problem of high turbidity in wastewater due to the lack of graded buffer space, making it difficult for natural sedimentation. Single-stage tanks cannot implement differentiated sedimentation for impurities of different particle sizes—coarse particles of silt accumulate rapidly at the inlet to form "channels," while fine particles continue to diffuse with the water flow, easily causing a vicious cycle of "local siltation + overall failure" in the sedimentation tank, requiring frequent shutdowns for dredging.

[0006] To address the aforementioned problems, the inventors propose a building wastewater treatment device. Utility Model Content

Detailed Implementation

[0023] 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.

[0024] Example: Figure 1-4As shown, this utility model provides a building wastewater treatment device, including a tank body 1. A sedimentation mechanism 2 is provided inside the tank body 1, and a sludge removal mechanism 3 is provided on the inner side of the sedimentation mechanism 2. The sedimentation mechanism 2 includes a primary sedimentation tank 20, a secondary sedimentation tank 24, and a tertiary sedimentation tank 25, which are sequentially arranged inside the tank body 1. An inlet 21 is provided on one side of the inner wall of the primary sedimentation tank 20, and a primary flow outlet 22 is provided on the other side of the inner wall of the primary sedimentation tank 20. A sedimentation pool 27 is fixedly provided on the lower inner wall of the secondary sedimentation tank 24. One side of the inner wall of the sedimentation pool 27 is fixedly connected to the primary flow outlet 22. Multiple filter ports 23 are provided on the outer side of the sedimentation pool 27. The inner wall of one side of the secondary sedimentation tank 24 is... A secondary flow outlet 26 is provided, which is fixedly connected to one side of the inner wall of the tertiary sedimentation tank 25. Wastewater enters the primary sedimentation tank 20 through the inlet 21 on one side of the inner wall of the primary sedimentation tank 20. Under the action of gravity, large particles of silt and other impurities in the wastewater begin to settle. At the same time, the wastewater flows through the primary flow outlet 22 into the sedimentation pool 27 fixed to the lower inner wall of the secondary sedimentation tank 24. Multiple filter outlets 23 on the outside of the sedimentation pool 27 perform preliminary filtration of the wastewater and further intercept impurities. The wastewater continues to settle in the sedimentation pool 27 and then flows into the tertiary sedimentation tank 25 through the secondary flow outlet 26, where it undergoes sedimentation treatment again. Through multi-stage sedimentation, silt and other impurities in the wastewater are effectively removed, achieving pretreatment before wastewater purification.

[0025] The sludge removal mechanism 3 includes a support frame 30, which is fixedly connected to the upper surface of the cylinder 1 and located above the primary sedimentation tank 20. A motor 31 is fixedly mounted on the upper surface of the support frame 30, and a rotating rod 34 is fixedly mounted on the output end of the motor 31. Multiple arc-shaped plates 38 arranged in a ring are fixedly mounted on the lower end of the rotating rod 34. Multiple breaking teeth 301 and brush bristles 39 are fixedly mounted on the lower surface of the arc-shaped plates 38. A sludge collection box 36 is fixedly mounted on the lower surface of the cylinder 1, and the upper surface of the sludge collection box 36 is fixedly connected to the lower inner wall of the primary sedimentation tank 20. A sludge suction pipe 35 is fixedly mounted on one side of the sludge collection box 36. A cover plate 302 is engaged on the lower surface of the primary sedimentation tank 20. When a certain amount of sludge accumulates in the primary sedimentation tank 20, most of the sewage is pumped out. The silt remaining at the bottom is removed. Then, using multiple lifting rings 303 fixed on the upper surface of the cover plate 302, the cover plate 302 is lifted by a hoisting device. After that, the motor 31 fixed on the upper surface of the support frame 30 is started. The output end of the motor 31 drives the rotating rod 34 to rotate. Multiple arc-shaped plates 38 fixed at the lower end of the rotating rod 34 rotate accordingly. Multiple crushing teeth 301 fixed on the lower surface of the arc-shaped plates 38 crush the hardened silt deposited at the bottom of the primary sedimentation tank 20, making it loose. At the same time, the brush 39 cleans the bottom of the primary sedimentation tank 20, sweeping the crushed silt into the sludge collection box 36. The sludge suction pipe 35 on one side of the sludge collection box 36 is connected to the external sludge suction equipment, and the sludge in the sludge collection box 36 is extracted by the sludge suction equipment.

[0026] A sedimentation chute 28 is provided on the lower inner wall of the primary sedimentation tank 20. The sedimentation chute 28 allows large particles of mud and sand and other impurities in the sewage in the primary sedimentation tank 20 to slide more smoothly down the chute during the flow process, which accelerates the sedimentation speed of impurities and improves sedimentation efficiency. At the same time, it avoids the local accumulation of impurities at the bottom of the tank, making the sedimentation effect more uniform.

[0027] Multiple sets of guardrails 37 are fixedly installed on the upper surfaces of the cylinder body 1 and the support frame 30. The guardrails 37 provide safety protection for workers when operating, maintaining or repairing the cylinder body 1 and the support frame 30, preventing workers from accidentally falling and ensuring their personal safety. They also avoid damage to the equipment that may be caused by accidental falls.

[0028] A mounting bracket 32 ​​is fixedly provided on the upper surface of the support frame 30. The upper surface of the mounting bracket 32 ​​is fixedly engaged with the motor 31. The mounting bracket 32 ​​provides a stable mounting platform for the motor 31, so that the motor 31 can be stably fixed on the support frame 30, reducing the vibration of the motor 31 during operation, ensuring the normal operation of the motor 31, extending the service life of the motor 31, and also contributing to the stability and reliability of the overall structure of the dredging mechanism 3.

[0029] A limiting frame 33 is fixedly provided on the lower surface of the support frame 30. The inner side of the limiting frame 33 is in rotational contact with the rotating rod 34. The limiting frame 33 plays a limiting and guiding role for the rotating rod 34, ensuring that the rotating rod 34 remains stable during rotation and will not shake or deviate. This ensures that the arc plate 38, the crushing tooth 301 and the brush bristles 39 can accurately carry out dredging operations at the bottom of the primary sedimentation tank 20, thereby improving the dredging effect and the stability of equipment operation.

[0030] Multiple lifting rings 303 are fixedly provided on the upper surface of the cover plate 302. The lifting rings 303 provide convenient leverage points for the lifting operation of the cover plate 302. When it is necessary to clean the silt in the sludge collection box 36, the cover plate 302 can be easily lifted by the lifting rings 303 through the lifting equipment, and the entrance of the sludge collection box 36 can be opened.

[0031] Among them, motor 31 is existing technology and will not be described in detail; at the same time, this utility model also includes power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail.

[0032] Working principle: Wastewater enters the primary sedimentation tank 20 through the inlet 21 on one side of the inner wall. Under the action of gravity, large particles of silt and other impurities in the wastewater begin to settle. At the same time, the wastewater flows into the sedimentation pool 27 fixed on the inner wall of the secondary sedimentation tank 24 through the primary flow port 22. Multiple filter ports 23 on the outside of the sedimentation pool 27 perform preliminary filtration of the wastewater and further intercept impurities. The wastewater continues to settle in the sedimentation pool 27 and then flows into the tertiary sedimentation tank 25 through the secondary flow port 26. In the tertiary sedimentation tank 25, sedimentation is carried out again. Through multi-stage sedimentation, silt and other impurities in the wastewater are effectively removed, realizing the pretreatment before wastewater purification.

[0033] When a certain amount of sludge accumulates in the primary sedimentation tank 20, most of the sewage is pumped out, leaving the sludge at the bottom. Then, using multiple lifting rings 303 fixed on the upper surface of the cover plate 302, the cover plate 302 is lifted by a hoisting device. After that, the motor 31 fixed on the upper surface of the support frame 30 is started. The output end of the motor 31 drives the rotating rod 34 to rotate. Multiple arc-shaped plates 38 fixed at the lower end of the rotating rod 34 rotate accordingly. Multiple crushing teeth 301 fixed on the lower surface of the arc-shaped plates 38 crush the hardened sludge deposited at the bottom of the primary sedimentation tank 20, making it loose. At the same time, the brush 39 cleans the bottom of the primary sedimentation tank 20, sweeping the crushed sludge into the sludge collection box 36. The sludge suction pipe 35 on one side of the sludge collection box 36 is connected to the external sludge suction equipment, and the sludge in the sludge collection box 36 is pumped out by the sludge suction equipment.
