Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a coal-containing wastewater filtering device. Background Art

[0002] Coal is the raw material for power generation in thermal power plants. The unloading, stacking and transfer system of raw coal is an important part of the power plant. After the raw coal enters the plant, it is first unloaded in the coal unloading system, then transported to the coal yard and dry coal shed by belts, and then transferred to the coal loading system of the boiler room by belts through several transfer stations.

[0003] During the unloading, stacking and transportation processes mentioned above, a large amount of dust or coal slag will be generated or fall on the floor. Since the floor needs to be regularly washed with water to keep the workshop clean, the water used to wash the floor will carry the coal powder or coal slag into the collection pool. If the coal-containing wastewater after washing is directly discharged, it will cause environmental pollution. Therefore, the wastewater needs to be treated to improve the utilization rate of water resources.

[0004] In fact, when the floor is flushed, in addition to a large amount of dust and coal slag, the floor also contains other debris, such as paper towels, plastic bags, gravel, etc. Some of these impurities are light in texture and some are heavy in texture. During the initial sedimentation in the sump, the light debris will float on the upper layer and the heavy debris will sink to the bottom of the water. When transported by a sweeping pump or other pump body, this debris may cause blockage to the pump body, and in severe cases, it may burn the pump body, thereby affecting the operation of the entire wastewater treatment system. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a coal-containing wastewater filtering device, wherein an inner shell is driven to rotate inside an outer shell by a driving device, and a cleaning fork is driven to rotate when the inner shell rotates, so that waste residues in the wastewater transported into the cleaning device are cleaned, thereby achieving separation of wastewater and waste residues, and preventing the waste residues from affecting components during subsequent wastewater treatment.

[0008] Preferably, a cleaning plate is slidably arranged on each row of the cleaning forks, a plurality of through holes matching the cleaning forks are arranged in an array on the cleaning plate, each of the cleaning forks passes through the through hole, and a limit block is arranged at the free end of the cleaning fork.

[0009] Preferably, the driving device comprises a first motor, the first motor is fixedly connected to the outer shell via a connecting plate, a driving wheel is mounted on a power output end of the first motor, and the driving wheel abuts against an inner wall of the inner shell.

[0010] Preferably, a waste water tank is provided at the water outlet, the waste water tank is connected with the interior of the cleaning device through the water outlet, and a waste residue tank is provided on the side of the waste water tank away from the cleaning device.

[0011] Preferably, an opening is provided at the top of the waste slag box, one end of the conveyor belt is located at the axis center of the inner shell body, and the other end of the conveyor belt is located at the top of the waste slag box.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] A coal-containing wastewater filtering device, the structure of which is as follows Figure 1-Figure 4 As shown, it includes a base 1, on which a cleaning device is arranged, and the cleaning device includes an outer shell 2, an inner shell 3 is movably sleeved inside the outer shell 2, both ends of the inner shell 3 have openings, one end of the outer shell 2 is provided with a first baffle 12, the lower half of the other end of the outer shell 2 is provided with a semicircular second baffle 13, and the upper half has an opening, the first baffle 12 is provided with a water inlet pipe 10, the second baffle 13 is provided with a water outlet 11, the horizontal height of the water inlet pipe 10 is higher than the horizontal height of the water outlet 11, the inner wall array of the inner shell 3 is provided with multiple rows of cleaning forks 5 arranged toward the axis of the inner shell 3, the outer shell 2 is provided with a driving device for driving the inner shell 3 to rotate, and a conveyor belt 14 for transmitting to the outside of the cleaning device is provided at the axis of the inner shell 3.

[0027] The waste water for washing the floor is transported into the cleaning device through the water inlet pipe 10, and the driving device is turned on. The driving device can drive the inner shell 3 to rotate inside the outer shell 2, and the waste water is inside the inner shell 3. Since the inner shell 3 drives the cleaning fork 5 to rotate simultaneously with the inner shell 3 when rotating, each row of cleaning forks 5 can alternately enter the waste water, and then drain the coal slag or waste residue in the waste water from the waste water. Since a conveyor belt 14 is provided at the axis of the inner shell 3, the cleaning fork 5 drives the coal slag or waste residue to rotate to the free end of the cleaning fork 5 obliquely downward. The coal slag or waste residue on the cleaning fork 5 will begin to slide toward the free end of the cleaning fork 5 until the cleaning fork 5 rotates to the top of the inner shell body 3, at which time the coal slag or waste residue on the cleaning fork 5 will completely fall onto the conveyor belt 14 at the axis of the inner shell body 3, so that the conveyor belt 14 can completely clean the waste residue or coal slag in the wastewater to the outside of the cleaning device, and the cleaned wastewater is discharged through the water outlet 11, so that the wastewater can be subsequently transported to the subsequent wastewater treatment device through the pump body, reducing the impact of the waste residue or coal slag in the wastewater on the pump body and ensuring the wastewater treatment efficiency.

[0028] The driving device includes a first motor 7 , which is fixedly connected to the outer shell 2 via a connecting plate 6 . A driving wheel 8 is installed at the power output end of the first motor 7 , and the driving wheel 8 abuts against the inner wall of the inner shell 3 .

[0029] The first motor 7 is fixedly installed on the top of the outer shell 2 through the connecting plate 6, and the power output end of the first motor 7 is toward the opening above the second baffle 13. The driving wheel 8 is driven to rotate by the power output end of the first motor 7. Since the driving wheel 8 is in contact with the inner wall of the inner shell 3, the inner shell 3 will rotate inside the outer shell 2 when the driving wheel 8 rotates, so as to drive the cleaning fork 5 to clean the waste water.

[0030] A waste water tank 16 is disposed at the water outlet 11 , and the waste water tank 16 is connected to the interior of the cleaning device through the water outlet 11 . A waste residue tank 4 is disposed on a side of the waste water tank 16 away from the cleaning device.

[0031] The waste water cleaned inside the cleaning device is discharged into the waste water tank 16 through the water outlet 11, so that the pump body can transport the waste water in the waste water tank 16 to the subsequent waste water treatment device, and the waste residue box 4 on one side of the waste water tank 16 is used to store the separated coal slag or waste residue and other debris.

[0032] The top of the waste slag box 4 is provided with an opening, one end of the conveyor belt 14 is located at the axis center of the inner shell 3, and the other end of the conveyor belt 14 is located at the top of the waste slag box 4.

[0033] The length of the cleaning fork 5 is greater than the height of the water outlet 11 from the bottom of the inner shell body 3, which makes it easy for the cleaning fork 5 to completely clean the waste slag or coal slag in the wastewater onto the conveyor belt 14. The waste slag cleaned out from the inside of the inner shell body 3 can be completely cleaned onto the conveyor belt 14 through the conveyor belt 14. Since the other end of the conveyor belt 14 is arranged at the top of the waste slag box 4, and an opening is provided at the top of the waste slag box 4, it is convenient for the conveyor belt 14 to transport the waste slag into the waste slag box 4.

[0034] A second motor 15 for driving the conveyor belt 14 is disposed at one end of the conveyor belt 14 located at the top of the waste slag box 4 , and a drainage hole is disposed on the surface of the conveyor belt 14 .

[0035] The second motor 15 can slowly drive the conveyor belt 14 to transport the waste residue on its surface to avoid a large amount of waste water on the waste residue. Therefore, the drainage holes on the surface of the conveyor belt 14 are convenient for further draining the waste water on its surface. The conveying speed of the second conveyor belt 14 is slow, which is convenient for the drainage holes to drain the waste water on the waste residue inside the cleaning device to avoid bringing the waste water to the outside of the cleaning device. An opening can also be opened on the top of the wastewater tank 16 to facilitate the waste water drained from the conveyor belt 14 to enter the wastewater tank 16.

[0036] Embodiment 2

[0037] On the basis of the first embodiment, a cleaning plate 9 is slidably arranged on each row of the cleaning forks 5, and a plurality of through holes matching the cleaning forks 5 are arranged in an array on the cleaning plate 9, and each of the cleaning forks 5 is arranged through the through holes, and a limit block 17 is arranged at the free end of the cleaning fork 5. The cleaning plate 9 and the cleaning fork 5 are both made of stainless steel.

[0038] When the floor is flushed, the wastewater may contain debris such as paper towels and plastic bags. When the debris follows the wastewater into the cleaning device, it will float on the water surface or suspend in the water. When the debris is cleaned by the cleaning fork 5, since the debris avoids containing water and the contact area between the debris and the cleaning fork 5 is large, the debris will stick to the cleaning fork 5, so as to prevent the debris from falling from the cleaning fork 5 to the conveyor belt 14. By providing a cleaning plate 9 that can slide on the cleaning fork 5, when it is inside the wastewater, the cleaning plate 9 abuts against the inner wall of the inner shell 3. When the inner shell 3 drives the corresponding cleaning fork 5 and the cleaning plate 9 to tilt upward, the cleaning plate 9 will slide toward the free end of the cleaning fork 5 until the cleaning fork 5 is driven to the top of the inner shell 3, and the cleaning plate 9 completely slides to the free end of the cleaning fork 5, so that the debris stuck on the cleaning fork 5 can be scraped off from the cleaning fork 5, so that the cleaning fork 5 can continue to clean the wastewater in the future, thereby improving the cleaning effect and cleaning efficiency of the device.

[0039] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or additions, subtractions or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
