Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically to an industrial wastewater treatment device. Background Technology

[0002] Wastewater is generated during the production of PCB boards, originating from processes such as etching, developing, electroplating, and cleaning. The wastewater contains solid waste, metal particles and precipitates, oil and organic impurities, and needs to be treated through steps such as sedimentation, oxidation, and degradation.

[0003] Because wastewater may contain non-degradable solid waste (such as gloves, cloth, and rubber) before it undergoes treatment, directly entering the sedimentation tank will occupy the space of the sedimentation tank and affect the sedimentation effect. Therefore, a screen is usually installed above the sedimentation tank to intercept it. However, the solid waste on the screen will accumulate over time and cause blockage. It is necessary to check the screen for blockage frequently by hand. In addition, the screen cannot perform preliminary separation of solid waste according to its size, which increases the workload of manual cleaning. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an industrial wastewater treatment device that can automatically clean and intercept components.

[0005] The technical solution adopted in this invention is as follows: An industrial wastewater treatment device includes an interception component, a control component, and a sealing component. The interception component intercepts solid waste in the wastewater. When the solid waste falls above the sealing component and the total weight of the solid waste reaches a preset value, the control component opens the discharge channel of the sealing component.

[0006] Compared with the prior art, the beneficial effects of the present invention are as follows: After sufficient weight of solid waste accumulates on the sealing component, the intercepting component and the sealing component descend to their lowest point. The control component then controls the sealing component to discharge the solid waste, thus replacing manual cleaning and avoiding the inability of humans to observe the blockage of the intercepting component in a timely manner.

[0007] In a preferred embodiment of the present invention, the interception component includes a frame, a filter plate is provided on the side of the frame facing the sedimentation tank, the sealing component includes a rotating plate, a rotating shaft is fixedly connected to the side of the rotating plate near the filter plate, the two ends of the rotating shaft are rotatably connected to the frame, the upper end face of the rotating plate abuts against the lower end face of the frame and the filter plate, and the control component controls the rotating plate to rotate around the rotating shaft, so that the rotating plate and the side wall of the frame form an opening for discharging solid waste.

[0008] Beneficial effects: Wastewater is discharged through the inlet pipe, and the water flow rushes towards and passes through the filter plate. Solid waste is intercepted on the inside of the filter plate and slides down to the top of the rotating plate, thus achieving the interception of solid waste. By setting a rotating plate, and restricting the rotation direction of the rotating plate by the filter plate and the frame, the rotating plate can only rotate downward to form an opening. The rotating plate is in an inclined state, and solid waste slides out from the opening. The water flow formed by the wastewater can wash the filter plate, making it less likely for the solid waste intercepted on the filter plate to adhere to the filter plate.

[0009] In a preferred embodiment of the present invention, a torsion spring is provided between the rotating shaft and the frame, and the control component includes an electromagnet. The electromagnet is located below the rotating plate. When the electromagnet is energized, it drives the rotating plate to rotate around the rotating shaft, and the torsion spring is compressed.

[0010] Beneficial effects: When the electromagnet is energized, it generates magnetic force, causing the rotating plate to approach the electromagnet and rotate around the axis. The torsion spring is compressed, forming an opening. When the electromagnet is de-energized, the rotating plate can be reset due to the torsion spring. Furthermore, when the rotating plate is in a horizontal state, the torsion spring already has a certain amount of compression, preventing the rotating plate from being pushed open due to the accumulation of solid waste.

[0011] In a preferred embodiment of the present invention, the filter plate includes a first filter plate and a second filter plate arranged sequentially from the outside to the inside, wherein the filter holes of the first filter plate are smaller than the filter holes of the second filter plate.

[0012] Beneficial effects: By setting up a first filter plate and a second filter plate with different pore sizes, the intercepted solid waste can be classified by volume.

[0013] In a preferred embodiment of the present invention, the filter plate further includes an upper limit plate, a baffle plate and a lower limit plate. The lower limit plate is fixedly connected to one side of the bottom surface of the second filter plate. The upper limit plate is vertically slidably mounted on the lower limit plate. The baffle plate is fixedly connected to the upper limit plate. The rotating plate supports the baffle plate. When the rotating plate is open, it includes a first state and a second state. The opening for discharging solid waste is located on the side of the second filter plate away from the first filter plate. When the rotating plate is in the first state, the upper limit plate slides down to contact the lower limit plate, and the blocking plate contacts the rotating plate. When the rotating plate is in the second state, the blocking plate is disengaged from the rotating plate.

[0014] Beneficial effects: When the rotating plate is in the first state, smaller volume solid waste is isolated between the first and second filter plates, while larger volume solid waste is discharged; when the rotating plate is in the second state, the upper limit plate is blocked by the lower limit plate, and the blocking plate cannot follow the rotating plate down, creating a gap between the rotating plate and the blocking plate. At this time, smaller volume solid waste can be discharged; by discharging solid waste in stages, it can be pre-screened, facilitating subsequent processing.

[0015] In a preferred embodiment of the present invention, a sliding hole is vertically provided on the lower limit plate, and a sliding block is fixedly connected to the lower end face of the upper limit plate, the sliding block being slidably installed in the sliding hole.

[0016] Beneficial effect: By placing the sliding hole and sliding block between the partition plate and the second filter plate, it is difficult for solid waste to enter the sliding hole.

[0017] In a preferred embodiment of the present invention, a limiting frame is installed on the sedimentation tank. The limiting frame is located below the frame body, and a compression spring is provided between the frame body and the limiting frame. A positioning plate is fixedly connected to the bottom surface of the frame body. The control component includes a photoelectric switch. When the positioning plate moves to the lowest point, the photoelectric switch sends an electrical signal to control the electromagnet to be energized.

[0018] Beneficial effects: By setting a compression spring, the height of the frame changes according to the weight of the solid waste inside the frame. When the positioning plate blocks the photoelectric switch, the photoelectric switch can be triggered.

[0019] In a preferred embodiment of the present invention, the positioning plate is in contact with the outer wall of the sedimentation tank, and the limiting frame is provided with a sliding groove on the side near the sedimentation tank, and the positioning plate is slidably connected to the sliding groove.

[0020] Beneficial effects: By setting a positioning plate, the sliding direction of the frame can be limited, preventing the spring from bending and causing the frame to deviate in the direction of movement. When the bottom of the frame is higher than the top surface of the sedimentation tank, the positioning plate is in contact with the outer wall of the sedimentation tank and still plays a guiding role. It also seals the gap between the bottom of the frame and the sedimentation tank, preventing sewage from flowing to the outside of the sedimentation tank.

[0021] In a preferred embodiment of the present invention, the limiting frame is provided with a first partition, a second partition and a third partition at intervals. When the rotating plate is in the first state, the opening is located between the first partition and the second partition, and the opening is located between the second partition and the third partition.

[0022] Beneficial effects: A first channel is formed between the first and second partitions, which can discharge large-volume solid waste; a second channel is formed between the second and third partitions, which can discharge smaller-volume solid waste; the rotation angle of the rotating plate is different in the first and second states. Since the rotation angle of the rotating plate is limited by the torsion spring, the rotation angle of the rotating plate can be adjusted by adjusting the magnetic force of the electromagnet, thereby realizing the adjustment of the two states.

Detailed Implementation

[0025] Typical embodiments embodying the features and advantages of the present invention will be specifically described in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0026] In the description of this application, the terms "first", "second", etc. are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] Example 1: See Figure 1 As shown, the industrial wastewater treatment equipment in this embodiment includes a sedimentation tank 4, an interception component 1, a control component 2, and a sealing component 3. Wastewater is discharged through an inlet pipe, passes through the interception component 1, and flows into the sedimentation tank 4. Solid waste is intercepted above the sealing component. When the total weight of the solid waste reaches a preset value, the control component 2 controls the sealing component 3 to open and discharge the solid waste.

[0028] Among them, see Figure 2 and Figure 3 As shown, a limiting frame 41 is installed on the sedimentation tank 4, and the limiting frame 41 has a vertical sliding groove on the side near the sedimentation tank 4; wherein, see reference Figure 8 As shown, the limiting frame 41 is provided with a first partition 42, a second partition 43 and a third partition 44 spaced apart. When the rotating plate 31 is in the first state, the opening is between the first partition 42 and the second partition 43, and between the second partition 43 and the third partition 44. A first channel is formed between the first partition 42 and the second partition 43, which can discharge solid waste with a larger volume. A second channel is formed between the second partition 43 and the third partition 44, which can discharge solid waste with a smaller volume.

[0029] Among them, see Figure 5 The water inlet pipe is a flexible hose 45. The upper part of the frame 11 is provided with a connection hole, and the flexible hose 45 is fixedly connected in the connection hole. The flexible hose 45 can move with the frame 11 within a certain range, so that the opening of the flexible hose 45 always faces the filter plate to adapt to the floating interception component 1.

[0030] In this embodiment, the water inlet pipe is controlled by a valve, and the valve is closed when the rotating plate 31 is opened.

[0031] Among them, see Figure 2 and Figure 3As shown, the interception component 1 includes a frame 11. A filter plate is provided on the side of the frame 11 facing the sedimentation tank 4. A compression spring 12 is vertically arranged between the frame 11 and the limiting frame 41. A positioning plate 15 is fixedly connected to the bottom surface of the frame 11. The positioning plate 15 contacts the outer wall of the sedimentation tank 4 and is slidably connected to the sliding groove. By setting the positioning plate 15, the sliding direction of the frame 11 can be limited to avoid the spring bending, which would cause the frame 11 to deviate in the direction of movement. When the bottom of the frame 11 is higher than the top surface of the sedimentation tank 4, the positioning plate 15 contacts the outer wall of the sedimentation tank 4 and still plays a guiding role. It also seals the gap between the bottom of the frame 11 and the sedimentation tank 4 to prevent sewage from flowing to the outside of the sedimentation tank 4.

[0032] Among them, see Figure 3 As shown, the filter plate includes a first filter plate 13 and a second filter plate 14 arranged sequentially from the outside to the inside. The filter holes of the first filter plate 13 are smaller than those of the second filter plate 14. By setting the first filter plate 13 and the second filter plate 14 with different filter hole sizes, the intercepted solid waste can be classified by volume.

[0033] Among them, see Figure 3 As shown, the enclosing component 3 includes a rotating plate 31 with a rotating shaft on it. The rotating shafts at both ends are rotatably mounted on the frame 11, and a torsion spring is provided between the rotating shaft and the frame 11. The control component 2 controls the rotation of the rotating plate 31. One side of the rotating plate 31 remains at a constant height, while the other side deflects downwards, causing the rotating plate 31 and the side wall of the frame 11 to form an opening for discharging solid waste. Wastewater is discharged through the inlet pipe, and the water flows towards and through the filter plate. Solid waste is intercepted inside the filter plate and slides down to the top of the rotating plate 31, thus achieving solid waste interception. By setting a rotatable rotating plate 31, an opening is formed after rotation. The rotating plate 31 is in an inclined state, and solid waste slides out from the opening.

[0034] In this embodiment, the rotating plate 31 is provided with an adsorption layer and an isolation layer from bottom to top. The adsorption layer is made of iron plate and the isolation layer is made of carbon fiber plate to prevent the metal objects above from being adsorbed and unable to detach from the rotating plate 31.

[0035] Among them, see Figure 3As shown, the control component 2 includes an electromagnet 21 and a photoelectric switch 22. When the positioning plate 15 moves to the lowest point, the photoelectric switch 22 sends an electrical signal to control the electromagnet 21 to be energized. The electromagnet 21 is located below the rotating plate 31 and on the side of the rotating shaft away from the sedimentation tank 4. When the electromagnet 21 is energized, it drives the rotating plate 31 to rotate around the rotating shaft. By setting a compression spring 12, the height of the frame 11 changes according to the weight of the solid waste inside the frame 11. The positioning plate 15 plays the role of triggering the photoelectric switch 22. After blocking the photoelectric switch 22, the photoelectric switch 22 can be triggered.

[0036] In this embodiment, the photoelectric switch 22 is model E3JK-DS30M1.

[0037] Among them, see Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, the filter plate also includes an upper limit plate 16, a baffle plate 17, and a lower limit plate 18. The lower limit plate 18 is fixedly connected to one side of the bottom surface of the second filter plate 14. The upper limit plate 16 is vertically slidably installed on the second filter plate 14. The baffle plate 17 is fixedly connected to the upper limit plate 16. The rotating plate 31 supports the baffle plate 17. When the rotating plate 31 is open, it includes a first state and a second state. The opening for discharging solid waste is located on the side of the second filter plate 14 away from the first filter plate 13. When the rotating plate 31 is in the first state, the upper limit plate 16 slides down to contact the lower limit plate 18, and the blocking plate 17 contacts the rotating plate 31. When the rotating plate 31 is in the second state, the blocking plate 17 is disengaged from the rotating plate 31.

[0038] When the rotating plate 31 is in the first state, smaller volume solid waste is isolated between the first filter plate 13 and the second filter plate 14, while larger volume solid waste is discharged. When the rotating plate 31 is in the second state, the upper limit plate 16 is blocked by the lower limit plate 18, and the blocking plate 17 cannot follow the rotating plate 31 down. There is a gap between the rotating plate 31 and the blocking plate 17. At this time, smaller volume solid waste can be discharged. By discharging solid waste in stages, solid waste can be pre-screened, which facilitates subsequent processing.

[0039] The lower limiting plate 18 has a vertically formed sliding hole, and a sliding block 19 is fixedly connected to the lower end face of the upper limiting plate. The sliding block 19 is slidably installed in the sliding hole. The usage method and principle of this embodiment are as follows: Wastewater is discharged through hose 45 and flows into sedimentation tank 4 after passing through second filter plate 14 and first filter plate 13 in sequence. Smaller solid waste is intercepted between the first filter plate 13 and the second filter plate 14, while larger solid waste is intercepted inside the second filter plate 14. The solid waste slides onto the rotating plate 31 due to gravity. Solid waste continuously accumulates on the rotating plate 31, increasing the overall gravity and compressing the compression spring 12. The frame 11, positioning plate 15, and rotating plate 31 descend synchronously. When the positioning plate 15 descends to its lowest point, it blocks the photoelectric switch 22. The photoelectric switch 22 sends an electrical signal, controlling the electromagnet 21 to be energized. The rotating plate 31 then rotates around its axis to the first state. Figure 5 As shown, the rotating plate 31 forms an opening at the bottom of the frame 11, the lower limit plate 18 slides down to contact the upper limit plate 16, the blocking plate 17 contacts the rotating plate 31, and the smaller volume of solid waste is isolated between the first filter plate 13 and the second filter plate 14, while the larger volume of solid waste is discharged into the first channel. Electromagnet 21 increases magnetic force, and rotating plate 31 is in the second state, such as... Figure 7 As shown, the upper limit plate 16 is blocked by the lower limit plate 18, and the blocking plate 17 cannot follow the rotating plate 31 to descend. There is a gap between the rotating plate 31 and the blocking plate 17. At this time, the smaller volume can be discharged into the second channel. By discharging solid waste in steps, solid waste can be pre-screened. Due to the elastic force of the torsion spring, the rotating plate 31 is reset, and due to the elastic force of the compression spring 12, the frame 11 is reset, thus completing the self-cleaning of the interception component 1.

[0040] Example 2: See Figure 9 Based on Embodiment 1, in this embodiment of the industrial wastewater treatment equipment, the control component 2 uses a pressure sensor to replace the positioning plate 15, compression spring 12 and photoelectric switch 22. The frame 11 is fixedly installed on the limit frame 41, and the total weight of solid waste in the frame 11 is monitored by the pressure sensor. The control component also includes a hydraulic rod 51, one end of which is hinged to the limit frame 41 and the other end of which is hinged to the rotating plate 31. The rotation of the rotating plate 31 is controlled by the extension and retraction of the hydraulic rod 51, which can replace the electromagnet.

[0041] In this embodiment, after the solid waste in the frame 11 reaches the preset value of the pressure sensor, the telescopic hydraulic rod 51 retracts a certain distance, so that the rotating plate 31 is in the first state. After a certain period of time, the telescopic hydraulic rod 51 retracts again, so that the rotating plate 31 is in the second state.

[0042] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
