Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for clean coal processing. Background Technology

[0002] Coal clean processing wastewater treatment equipment is a complete set of equipment specifically designed to treat wastewater generated during clean coal processing. Its function is to remove pollutants from wastewater through a combination of physical, chemical, and biological processes, enabling the wastewater to meet discharge standards or be recycled, thereby reducing environmental pollution and improving water resource utilization efficiency.

[0003] Traditional equipment experiences systemic and cascading disruptions to the wastewater treatment process when replacing filters or cleaning filter cake. The fixed connection between filters and treatment devices in most traditional equipment involves bolts or welding to rigidly connect the filters to the filtration tank. When filter efficiency decreases due to filter cake blockage, or when the filter media reaches the end of its lifespan and needs replacement, the inlet valve must be shut off first. Only after the residual wastewater in the filtration tank is drained can the connecting parts be disassembled. Upstream water cannot enter the treatment device and must be temporarily stored in the equalization tank. If the equalization tank is insufficient in volume, it can lead to wastewater overflow risks, severely impacting the continuous production of clean coal processing.

[0004] When replacing filters or cleaning filter residue in existing equipment, the wastewater treatment process must be interrupted. Since filters and treatment devices are mostly fixedly connected, the machine must be stopped before disassembly, which leads to the interruption of wastewater treatment. This not only reduces the overall treatment efficiency, but also affects the stable operation of subsequent processes due to wastewater accumulation. Utility Model Content

Two slag discharge channels are located on the left side of the filtration tank, with the bottoms of the two filters slidably connected to the tops of the two slag discharge channels. Mounting components are located on the opposite sides of the two filters. Limiting mechanisms are located on the front and rear sides of the middle of the filtration tank. An outlet is connected to the bottom right side of the filtration tank.

[0009] As a further description of the above technical solution: The settling mechanism includes a funnel, the top of which is fixedly connected to the bottom of the mixing tank.

[0010] As a further description of the above technical solution: The mounting assembly includes multiple hinges, the tops of which are respectively fixedly connected to the tops of the two filters on opposite sides, and a baffle is fixedly connected to the opposite sides of each of the multiple hinges.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0019] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a coal cleaning processing wastewater treatment device, including a filter tank 1, a mixing tank 2 arranged on the right side of the filter tank 1, a flow exchange mechanism 3 arranged on the top of the filter tank 1 for flow exchange, a filter mechanism 4 arranged on the top of the inner side of the filter tank 1, a mixing mechanism 5 arranged on the top of the mixing tank 2 for mixing drugs, and a settling mechanism 6 arranged on the right side of the mixing tank 2. The converter 3 includes a protective cover 31. The bottom of the protective cover 31 is fixedly connected to the top of the filter tank 1. Multiple water pipe ports 32 are opened on the left and right sides of the protective cover 31. A diversion pipe 33 is fixedly connected inside the water pipe port 32. Two valves 34 are fixedly connected to the outer wall of the diversion pipe 33. Gear 1 35 is rotatably connected to the top of each of the two valves 34. The same gear 2 36 is meshed between adjacent gears 1 35. A connecting column 37 is fixedly connected to the bottom of gear 2 36. A knob 38 is fixedly connected to the bottom of the connecting column 37. Specifically, the wastewater from coal cleaning and processing enters the filter tank 1. Under the action of the filtration mechanism 4, suspended particulate matter in the wastewater is intercepted. The preliminarily purified wastewater flows to the mixing tank 2. During this process, the water flow state in the filter tank 1 can be adjusted by the flow exchange mechanism 3. Rotating the knob 38 drives the gear 2 36 to rotate through the connecting column 37. The gear 2 36 meshes with two gears 1 35, thereby driving the two gears 1 35 to rotate synchronously. The rotation of gears 1 35 changes the opening and closing state of the two valves 34. The opening and closing of the valves 34 adjusts the water flow direction and flow rate in the diversion pipe 33. The diversion pipe 33 cooperates with the protective cover 31 through the water pipe outlet 32 ​​to realize the flow exchange control of the water flow in the filter tank 1. Through the meshing transmission of gear 2 36 and gear 1 35, and the cooperation of valve 34 and diversion pipe 33, the stable adjustment of the water flow state in the filter tank 1 is realized, ensuring that the filtration process proceeds in an orderly manner. When the wastewater enters the mixing tank 2, the mixing mechanism 5 is activated to fully mix the required treatment drugs with the wastewater, causing the drugs to react chemically with the pollutants in the wastewater. The mixed wastewater then enters the settling mechanism 6. In the settling mechanism 6, the flocs or sediments formed by the chemical reaction gradually settle under gravity. The clear water at the top is discharged as the treated water, completing the entire treatment process. Through filtration by the filtration mechanism 4, water flow regulation by the exchange mechanism 3, drug mixing by the mixing mechanism 5, and sedimentation separation by the settling mechanism 6, effective purification of coal clean processing wastewater is achieved.

[0020] Reference Figure 1 and Figure 4 The mixing mechanism 5 includes a water inlet pipe 52, the bottom right side of which is connected to the top left end of the mixing tank 2, a water pump 51 connected to the bottom left side of the water inlet pipe 52, an outlet 48 connected to the left side of the water pump 51, a motor 53 fixedly connected to the top center of the mixing tank 2, the output end of the motor 53 passing through the top of the mixing tank 2, a stirrer 54 fixedly connected to the output end of the motor 53, a drug delivery pipe 55 connected to the top front end of the mixing tank 2, a water pump 56 connected to the bottom front side of the drug delivery pipe 55, a drug tank 57 connected to the front side of the water pump 56, and a drug addition mechanism 58 provided on the top of the drug tank 57. Specifically, the coal cleaning and processing wastewater to be treated enters the filter tank 1. Under the action of the filter mechanism 4, the suspended particulate matter in the wastewater is intercepted. The preliminarily purified wastewater enters the water pump 51 through the outlet 48. The water pump 51 transports the wastewater to the inlet pipe 52. The wastewater flows into the mixing tank 2 through the inlet pipe 52. Through the power transmission of the water pump 51 and the passage guidance of the inlet pipe 52, the wastewater is stably transferred from the filtration stage to the mixing stage. At the same time, the medicine in the medicine tank 57 enters the mixing tank 2 through the delivery pipe 55 under the action of the second water pump 56. The dosing mechanism 58 on the top of the medicine tank 57 can replenish the medicine in the medicine tank 57. Driven by the second water pump 56, the medicine is added to the medicine tank 57. The delivery pipe 55 enables a continuous supply of drugs to the mixing tank 2. When wastewater and drugs enter the mixing tank 2, the motor 53 at the top center of the mixing tank 2 starts. Its output end passes through the top of the mixing tank 2 and drives the agitator 54 to rotate. The rotation of the agitator 54 makes the wastewater and drugs in the tank fully contact and mix. Through the power output of the motor 53 and the mechanical stirring of the agitator 54, the drugs and wastewater are uniformly mixed, which promotes the reaction between the drugs and pollutants in the wastewater. During this process, the water inlet pipe 52 and the delivery pipe 55 introduce fluid from the top left end and front end of the mixing tank 2, respectively. With the full-area stirring of the agitator 54, the mixing efficiency is further improved.

[0021] Reference Figure 3 , Figure 4 and Figure 5 The filtration mechanism 4 includes two filters 41, with each filter 41 positioned on its left and right sides in the middle of the inner side of the filtration tank 1. Each filter 41 has two mounting grooves 42 inside. Activated carbon 43 is slidably connected inside the two bottom mounting grooves 42, and filter screens 44 are slidably connected inside the two top mounting grooves 42. Two slag discharge channels 45 are provided on the left side of the filtration tank 1. The bottoms of the two filters 41 are slidably connected to the tops of the two slag discharge channels 45. Mounting components 46 are provided on the opposite sides of each filter 41. Limiting mechanisms 47 are provided on the front and rear sides of the middle of the filtration tank 1. The bottom right side of the filtration tank 1 is connected to an outlet. Water outlet 48, settling mechanism 6 includes funnel 61, the top of funnel 61 is fixedly connected to the bottom of mixing tank 2, the bottom of funnel 61 is connected to connecting pipe 62, the right side of connecting pipe 62 is connected to water pump 3 63, the top of water pump 3 63 is connected to water outlet pipe 64, the right side of water outlet pipe 64 is connected to settling tank 65, the right side of settling tank 65 is connected to water outlet 2 66, the bottom front side of settling tank 65 is provided with sediment removal mechanism 67, mounting component 46 includes multiple hinges 461, the tops of multiple hinges 461 are respectively fixedly connected to the top of the two filters 41 on opposite sides, and the opposite sides of multiple hinges 461 are respectively fixedly connected to baffle 1 462; Specifically, the wastewater to be treated enters the filter tank 1. Under the action of the limiting mechanism 47, the two filters 41 are stably positioned in the middle of the inner side of the filter tank 1. The wastewater flows through the filters 41. The filter screen 44 in the top mounting groove 42 intercepts larger particulate impurities, and the activated carbon 43 in the bottom mounting groove 42 adsorbs pollutants. Through the interception of the filter screen 44 and the adsorption of the activated carbon 43, the wastewater is initially purified. The treated wastewater is discharged through the outlet 48. When the filters 41 need to be cleaned, the baffle 462 is rotated by the hinge 461 to remove the filters 41 from the inner side of the filter tank 1. The bottom of the filters 41 slides along the sludge discharge slide 45, causing the filter sludge to detach from the filters 41. 1. After cleaning, reset the filter 41 and close the baffle 462 via hinge 461 to ensure continuous filtration. The mixed wastewater enters the connecting pipe 62 through the funnel 61 and is sent to the settling tank 65 through the outlet pipe 64 under the action of the water pump 63. The wastewater settles in the settling tank 65, and the flocs or sediments formed by the chemical reaction gradually settle. The clear water on the upper layer is discharged through the outlet 66. Through the guidance of the funnel 61 and the transportation of the water pump 63, the wastewater is stably transferred to the settling tank 65. Through the settling action of the settling tank 65, solid-liquid separation is achieved. The sediment removal mechanism 67 at the bottom front of the settling tank 65 can treat the sediment at the bottom.

[0022] Reference Figure 3 , Figure 4 and Figure 5 The limiting mechanism 47 includes two limiting plates 472, the bottom of which is located inside the filter tank 1. Two limiting grooves 471 are opened inside the filter tank 1. The bottom of the two limiting plates 472 is slidably connected to the top of the two limiting grooves 471 respectively. The dosing mechanism 58 includes a hinge 581. The rear bottom of the hinge 581 is fixedly connected to the top of the medicine tank 57. A partition 582 is fixedly connected to the rear bottom of the hinge 581. The sediment removal mechanism 67 includes a second baffle 672. The bottom of the second baffle 672 is located at the front bottom of the settling tank 65. A connecting groove 671 is opened at the front bottom of the settling tank 65. The outer wall of the second baffle 672 is slidably connected to the inside of the connecting groove 671. Specifically, the coal cleaning and processing wastewater to be treated enters the filter tank 1. The limiting mechanism 47 limits the position of the filter 41. The bottoms of the two limiting plates 472 are set inside the filter tank 1, and their bottoms are slidably connected to the tops of the two limiting grooves 471, so that the filter 41 is stably positioned in the filtration position. The wastewater flows through the filter 41. The filter screen 44 in the top mounting groove 42 intercepts larger particulate impurities, and the activated carbon 43 in the bottom mounting groove 42 adsorbs pollutants. Through the cooperation of the limiting plates 472 and the limiting grooves 471, the filter 41 is stably positioned, ensuring that the filtration process proceeds in an orderly manner. When the filter 41 needs to be cleaned, the hinge 461 of the installation component 46 is operated to open the baffle 462, the filter 41 is taken out and the filter residue is cleaned along the slag discharge slide 45, and after resetting, the baffle 462 is closed. The filtered wastewater enters the water pump 5 through the outlet 48. 1. Water pump 51 delivers water into mixing tank 2 via inlet pipe 52. During dosing, the partition 582 is rotated by hinge 581 of dosing mechanism 58 to add medicine to medicine tank 57, and then the partition 582 is closed. The medicine enters mixing tank 2 via water pump 56 and dosing pipe 55. Motor 53 drives stirrer 54 to rotate, so that wastewater and medicine are fully mixed. The cooperation between hinge 581 and partition 582 enables convenient replenishment of medicine. The cooperation between motor 53 and stirrer 54 enables uniform mixing of wastewater and medicine. The mixed wastewater enters settling tank 65 through funnel 61, connecting pipe 62, water pump 63, and outlet pipe 64. After settling, the upper clear water is discharged through outlet 66. When cleaning sediment, baffle 672 in sliding connecting groove 671 is used to discharge sediment. The cooperation between connecting groove 671 and baffle 672 enables convenient cleaning of sediment.

[0023] Working principle: The coal cleaning and processing wastewater to be treated first enters the filter tank 1. Under the action of the limiting mechanism 47, the limiting plate 472 slides inside the limiting groove 471, thereby limiting the position of the filter 41 and keeping the filter 41 stably in the filtration position, ensuring that the wastewater can flow steadily through the filter 41. Under the action of the filtration mechanism 4, the filter screen 44 inside the filter 41 intercepts larger particulate impurities in the wastewater, and the activated carbon 43 further adsorbs pollutants in the wastewater. Through this dual treatment, suspended particulate matter in the wastewater is effectively intercepted. The preliminarily purified wastewater is discharged from the filter tank 1 through the outlet 48. When treating the filter residue, the water flow direction can be adjusted by operating the flow exchange mechanism 3. Rotating the knob 38 drives the gear 36 to rotate through the connecting column 37. The gear 36 meshes with the two gears 35, and the water flows through the filter tank 1. The two gears 35 rotate synchronously, which changes the opening and closing state of the two valves 34. The opening and closing of the valves 34 adjusts the water flow direction in the diversion pipe 33. The diversion pipe 33 cooperates with the protective cover 31 through the water pipe port 32 to realize the exchange control of the water flow in the filter tank 1, ensuring the stable operation of the filtration process. When the filter 41 needs to be cleaned, the rotation characteristics of the hinge 461 are used to open the baffle 462, and the filter screen 44 and activated carbon 43 are taken out from the middle of the inner side of the filter 41. After the flow is exchanged, the limit plate 472 is opened, allowing the filter 41 to enter the sludge discharge slide 45. The filter sludge is poured out through the sludge discharge slide 45. After the filter sludge is cleaned, the filter 41 is reinstalled and the baffle 462 is closed. At the same time, the limit plate 472 is closed, allowing the filter 41 to reset and continue filtration, ensuring the continuous operation of the filtration process. The filtered wastewater discharged through outlet 48 enters pump 51, which transports the wastewater to inlet pipe 52. The wastewater flows into mixing tank 2 through inlet pipe 52. The medicine in medicine tank 57 enters mixing tank 2 through delivery pipe 55 under the action of pump 56. The dosing mechanism 58 on top of medicine tank 57 can replenish medicine into medicine tank 57. When adding medicine, the partition 582 is rotated by hinge 581 to add medicine into medicine tank 57. Closing partition 582 completes the dosing operation. When the wastewater enters mixing tank 2, mixing mechanism 5 starts and motor 53 starts. Its output end drives stirrer 54 to rotate in mixing tank 2. The rotation of stirrer 54 makes the wastewater and medicine in mixing tank 2 fully contact and mix, promoting chemical reaction between medicine and pollutants in wastewater. The mixed wastewater then enters the settling mechanism 6, passes through the funnel 61 and connecting pipe 62, and enters the settling tank 65 through the outlet pipe 64 under the action of the water pump 63. In the settling mechanism 6, the flocs or sediments formed by the chemical reaction gradually settle under the action of gravity. The sediments generated during the settling process accumulate at the bottom of the settling tank 65, and the clear water on the upper layer is discharged as treated water through the outlet 66. When cleaning the sediment, the baffle 672 in the sliding connecting trough 671 is used to discharge the bottom sediments through the sediment removal mechanism 67, thus completing the entire treatment process of coal cleaning processing wastewater.
