Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a water treatment device for underground wastewater sedimentation and filtration. Background Technology

[0002] Coal mining underground generates a large amount of wastewater (such as tunneling wastewater, equipment cooling water, dust suppression water, etc.), which contains a large amount of solid particulate impurities such as coal slime and rock powder. Direct discharge of this wastewater will pollute the underground working environment and may even cause equipment failure or safety hazards. Current technologies mostly employ centralized surface treatment for underground wastewater, but this approach has the following drawbacks:

[0003] The sedimentation process is difficult to clean: Traditional sedimentation tanks have a flat bottom structure, making it difficult for solid particles to accumulate quickly. The sludge after sedimentation adheres to the bottom of the tank, requiring manual cleaning or mechanical excavation, which is labor-intensive and can easily cause secondary pollution.

[0004] Cleaning after filtration is difficult: Most traditional filters have built-in filter screens. When too much impurities accumulate on the filter screen, it can only be cleaned by disassembly, which is time-consuming and laborious. Utility Model Content

[0005] A water treatment device for sedimentation and filtration of sewage in wells includes a water sedimentation device and a water filtration device installed above the water sedimentation device. The water sedimentation device includes a sedimentation platform above the ground, a sedimentation tank installed on the sedimentation platform, a sewage pipe connected to the sedimentation tank and leading out from the sedimentation platform, and at least one drainage pipe connected to the sedimentation tank and higher than the sewage pipe. A sedimentation trough connected to the sewage pipe is opened in the center of the bottom of the sedimentation tank. The bottom of the entire sedimentation tank slopes down towards the location of the sedimentation trough.

[0006] By adopting the above scheme, when the wastewater of the water treatment equipment is filtered and enters the sedimentation tank, the bottom of the tank gradually decreases from the periphery to the center of the sedimentation tank, forming a slope, which facilitates the natural collection of sludge into the sedimentation tank. Later, the sewage pipe can be directly opened to discharge all the impurities, making it more convenient to clean the impurities.

[0007] As a preferred embodiment of a water treatment device for underground sewage sedimentation and filtration, an automatic cleaning mechanism for cleaning the bottom of the sedimentation tank is provided above the center of the sedimentation tank in a rotating manner to facilitate automatic cleaning of the tank bottom. The automatic cleaning mechanism includes a mounting frame, a motor fixed above the mounting frame, and a cleaning frame concentrically connected to the motor shaft and always in contact with the bottom of the tank. During cleaning, the cleaning frame is driven by the motor to rotate and clean the bottom of the tank. The cleaning frame consists of two sets of symmetrical cleaning frames on the left and right sides. Each set of cleaning frames can cover half of the bottom of the sedimentation tank and there are no dead angles when rotating.

[0008] As a preferred embodiment of a water treatment device for sedimentation and filtration of underground sewage, the sedimentation tank is composed of multiple modular tank walls spliced ​​together. The modular tank walls are standardized prefabricated components that can be quickly sealed and spliced ​​by bolts or clips, making it easy to adjust the size of the sedimentation tank according to the size of the underground tunnel.

[0009] The second technical problem this invention aims to solve is to provide a water treatment device for sedimentation and filtration of underground sewage that can easily clean impurities in the filter tank.

[0010] The technical solution of this utility model is implemented as follows:

[0011] Based on the above scheme, the water filtration equipment includes a stand installed directly above the sedimentation tank, a filter tank fixedly installed above the stand, and an inlet pipe connected to one end of the filter tank. The filter tank has an outlet at the end away from the inlet pipe, which is located outside the sedimentation tank. After filtration, the impurities in the wastewater can be directly discharged or enter the subsequent treatment system, making it more convenient to clean the impurities. The filter tank slopes down from the end where the inlet pipe is located to the end where the outlet is located, with an inclination angle of 5°-15°, which facilitates the natural flow of wastewater and improves the filtration efficiency.

[0012] As a preferred embodiment of a water treatment device for sedimentation and filtration of underground sewage, vertical baffles are provided on both sides of the filter tank. The baffles are made of stainless steel or high-strength plastic. The height of the vertical baffles is higher than the height of the outlet of the inlet pipe, which can prevent sewage from splashing out or impurities from splashing during filtration.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] 1. When the wastewater of this water treatment equipment is filtered and enters the sedimentation tank, the bottom of the tank gradually decreases from the periphery to the center of the sedimentation tank, forming a slope, which facilitates the natural collection of sludge into the sedimentation tank. Later, the sewage pipe can be directly opened to discharge all the impurities, making it more convenient to clean the impurities.

[0015] 2. To facilitate automatic cleaning of the bottom of the sedimentation tank, an automatic cleaning mechanism that rotates to clean the bottom of the tank is installed above the center of the sedimentation tank. The cleaning frame is driven by a motor to rotate and clean the bottom of the tank, and there are no blind spots when rotating.

[0016] 3. The sedimentation tank is composed of multiple modular tank walls, which are standardized prefabricated components, making it easy to adjust the size of the sedimentation tank according to the dimensions of the underground tunnel.

[0017] 4. The water filtration equipment uses an external filter tank for filtration. After the wastewater is filtered, the impurities can be directly discharged or enter the subsequent treatment system, which makes it more convenient to clean the impurities. In addition, the filter tank is tilted and lowered to facilitate the natural flow of wastewater and improve the filtration efficiency. Attached Figure Description

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.

[0027] like Figures 1 to 4As shown, a water treatment device for sedimentation and filtration of underground sewage is provided. It is used to treat sewage such as tunneling wastewater, equipment cooling water, and dust suppression spraying. Specifically, it includes a water sedimentation device and a water filtration device installed above the water sedimentation device. The water sedimentation device includes a sedimentation platform 1 (constructed with reinforced concrete, 0.8m high, 6m×6m×1.2m in size) above the ground, a sedimentation tank 2 (4.5m in diameter) installed on the sedimentation platform 1, a sewage pipe 3 (200mm in diameter) connecting the sedimentation tank 2 and leading out from the sedimentation platform 1, and three drainage pipes 4 (200mm in diameter) connecting the sedimentation tank 2 and being higher than the sewage pipe 3. A sedimentation trough 5 (1.5m in diameter, 0.5m deep) connected to the sewage pipe 3 is opened in the center of the bottom of the sedimentation tank 2. The bottom of the entire sedimentation tank 2 slopes down towards the sedimentation trough 5 as the center. When the wastewater from this water treatment equipment is filtered and enters the sedimentation tank 2, the bottom of the tank gradually decreases from the periphery to the center of the sedimentation tank 5, forming a slope, which facilitates the natural collection of sludge into the sedimentation tank 5. Later, the sewage pipe 3 can be directly opened to discharge all the impurities, making it more convenient to clean the impurities. When the water level reaches the location of the drain pipe 4, the purified water will flow out of the drain pipe 4.

[0028] like Figures 3 to 4 , Figure 6 As shown, to facilitate automatic cleaning of the bottom of the sedimentation tank 2, an automatic cleaning mechanism that rotates to clean the bottom of the tank is provided above the center of the sedimentation tank 2. The automatic cleaning mechanism includes a mounting frame 6 (height 1.5m), a motor 7 (power 1.5kW, speed 30r / min) fixed above the mounting frame 6, and cleaning frames 8 (each set is 3m×0.8m in size) concentrically connected to the rotating shaft of the motor 7 and always in contact with the bottom of the tank. The bottom of the cleaning frame is equipped with nylon bristles (hardness 60A, length 20mm), and the contact pressure with the bottom of the tank is 0.1MPa. During cleaning, the cleaning frame 8 is driven by the motor 7 to rotate and clean the bottom of the tank. The cleaning frame 8 consists of two sets of symmetrical cleaning frames on the left and right sides. Each set of cleaning frames can cover half of the bottom of the sedimentation tank 2, and there are no dead angles when rotating.

[0029] like Figures 1 to 4 As shown, sedimentation tank 2 is composed of twelve modular tank walls. The modular tank walls are standardized prefabricated components that can be quickly sealed and assembled using bolts or clips, making it easy to adjust the size of sedimentation tank 2 according to the dimensions of the underground tunnel.

[0030] like Figures 5 to 6As shown, the water filtration equipment includes a stand 9 (2.0m high) installed directly above the sedimentation tank 2, a filter tank 10 (5.5m × 0.8m × 0.3m) fixedly installed above the stand 9, and an inlet pipe 11 (150mm in diameter) connected to one end of the filter tank 10. The filter tank 10 has an outlet at the end away from the inlet pipe 11, which is located outside the sedimentation tank 2. After filtration, the impurities in the wastewater can be directly discharged or enter the subsequent treatment system, making it more convenient to clean the impurities. The filtered wastewater will fall into the sedimentation tank 2. The filter tank 10 is inclined downward from the end where the inlet pipe 11 is located to the end where the outlet is located, with an inclination angle of 8°, which facilitates the natural flow of wastewater and improves the filtration efficiency.

[0031] As a preferred embodiment of a water treatment device for sedimentation and filtration of underground sewage, vertical baffles 12 (0.6m high) are provided on both sides of the filter tank 10. The baffles are made of 304 stainless steel. The height of the vertical baffles 12 is higher than the height of the outlet of the inlet pipe 11, which can prevent sewage from splashing out or impurities from splashing during filtration.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
