Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly relates to an industrial wastewater zero-discharge treatment device. Background Art

[0002] During the industrial production process, water sources are often required according to the manufacturing requirements of products. After use, industrial wastewater cannot be directly discharged into the environment due to containing different pollutants. For example, in the machining industry, after the parts are processed, water is needed to clean the oil stains, chips, machining fluids and other impurities on the surface of the parts, resulting in wastewater containing oil and metal chips, while the wastewater of the clothing industry often contains fiber debris such as fabrics.

[0003] When the prior art purifies industrial wastewater, workers usually need to fish out the pollutants in the wastewater, and then further purify the wastewater after fishing and cleaning. When the content of industrial wastewater is large, a large number of workers are required to carry out the pollutant fishing work, increasing the labor cost, and the volume of the fished pollutants is large, which requires a large amount of space during storage or transportation. Summary of the Invention

[0004] In order to solve the above technical problems in the prior art, the present invention provides an industrial wastewater zero-discharge treatment device.

[0005] The industrial wastewater zero-discharge treatment device provided by the present invention adopts the following technical scheme:

[0006] An industrial wastewater zero-discharge treatment device includes a wastewater tank. There is a feeding port at the top of the wastewater tank. A flow guide cover is arranged on the outer wall on one side of the feeding port. The upper end of the flow guide cover is communicated with the feeding port. Among them, a floating object filter plate is longitudinally slidably arranged on the inner wall of the feeding port in the direction away from the flow guide cover. A one-way rotation assembly is arranged at the end of the floating object filter plate. After the floating object filter plate moves to a position close to the flow guide cover, the floating object filter plate is controlled to rotate towards the flow guide cover through the one-way rotation assembly, so that the floating pollutants filtered by the floating object filter plate flow into the flow guide cover.

[0007] A water tank is arranged at the bottom of the wastewater tank. A transmission filter pipeline for filtering and transmitting the sediment in the wastewater is arranged between the wastewater tank and the water tank. A flow guide pipe is arranged at the bottom of the flow guide cover. The transmission filter pipeline is communicated with the flow guide pipe. A filter screen for filtering the wastewater and a spiral guide rod for transmitting the pollutants into the interior of the flow guide pipe are arranged in the transmission filter pipeline. A compression cavity assembly is arranged at the bottom of the flow guide pipe. A compression plate for compressing the pollutants and an elastic push shaft for discharging the garbage are arranged in the compression cavity assembly.

[0008] Further, a screw rod for driving the floating object filter plate to move on the inner wall of the wastewater tank is rotatably connected to the outer side wall of the wastewater tank. An electric motor for driving the screw rod to rotate is fixedly installed outside the wastewater tank. The screw rod is connected to the electric motor through a synchronous belt. The above-mentioned one-way rotation assembly is threadedly connected to the screw rod.

[0009] Further, the one-way rotation assembly includes a driving seat. The driving seat is threadedly connected to the screw rod. A connecting shaft is provided at the upper end of the floating object filter plate. The connecting shaft penetrates through the driving seat and is rotatably connected to the driving seat. A second driving plate and a first driving plate are provided on the connecting shaft at the top of the floating object filter plate. The second driving plate is arranged inside the driving seat, and the first driving plate is arranged outside the driving seat. A side baffle is protruded upward from the upper part of the side wall of the wastewater tank. By making the side baffle abut against the second driving plate, the floating object filter plate is in a vertical state. A stop post is provided on the side of the driving seat. The stop post is located at the lower end of the first driving plate. When the floating object filter plate is moved forward, the first driving plate abuts against the stop post to prevent the floating object filter plate from moving in the opposite direction.

[0010] Further, an elastic connection pin is slidably arranged on the side of the driving seat. A connection ring is fixedly arranged around the elastic connection pin. An elastic element is arranged between the connection ring and the driving seat. A positioning hole is provided on the connecting shaft at the top of the floating object filter plate. Under the elastic force of the above elastic element, the elastic connection pin can be inserted into the positioning hole of the connecting shaft at the top of the floating object filter plate, so that the floating object filter plate can maintain an inclined state, thereby preventing the floating object filter plate from filtering the floating objects in the wastewater in the reverse direction.

[0011] Further, an unlocking cross plate is fixedly arranged to extend outward from the side of the side baffle. An open groove is formed in the upper part of the unlocking cross plate. The bottom of the open end of the open groove has an inclined downward guiding slope. The elastic connection pin can move into the open groove in the unlocking cross plate. When the floating object filter plate moves in the opposite direction after clearing the floating pollutants in the wastewater, the elastic connection pin moves into the open groove in the unlocking cross plate. Under the resistance of the guiding slope in the unlocking cross plate, the connection ring in the elastic connection pin moves to the bottom of the unlocking cross plate, and then the upper end of the elastic connection pin moves downward out of the positioning hole of the connecting shaft in the floating object filter plate, so that the floating object filter plate can rotate to a vertical state.

[0012] Further, a bogie is arranged outside the side wall of the wastewater tank near one end of the flow guide cover. A guide plate is provided at the top of the bogie. A second guiding slope is provided on the side of the guide plate away from the flow guide cover. The guide plate at the top of the bogie corresponds to the position of the first driving plate.

[0013] Furthermore, the specific structure of the transfer filtration pipeline includes a filtration pipeline. One end of the filtration pipeline is connected to the diversion pipe, and the other end is connected to the wastewater tank. The connection end of the filtration pipeline to the diversion pipe is higher than the connection end of the filtration pipeline to the wastewater tank, so that the wastewater in the filtration pipeline flows into the wastewater tank. A valve for restricting the flow rate is provided between the filtration pipeline and the wastewater tank. A filter screen is provided at the bottom of the filtration pipeline, and the filter screen is connected to the water tank. The filtered wastewater flows into the water tank through the filter screen. A spiral guide rod for driving the pollutants in the filtration pipeline to move into the diversion pipe is rotatably connected inside the filtration pipeline. A coupling is connected to one end of the filtration pipeline away from the diversion pipe. One end of the coupling is connected to the filtration pipeline, and the other end is connected to a linkage shaft. The linkage shaft is connected to the motor through a synchronous belt.

[0014] Furthermore, there is a chemical dosing barrel for adding decontamination chemicals outside the water tank. The chemical dosing barrel is connected to the water tank. An internal motor is provided at the upper end inside the water tank, and a stirring structure is connected to the bottom of the internal motor. An outlet is provided at a position above the bottom of the water tank, and a sediment discharge port is provided at the bottom of the water tank. The purified water after being treated with the decontamination chemical is discharged out through the outlet. Valves for restricting the flow rate are provided at both the outlet and the sediment discharge port.

[0015] Furthermore, a compression chamber assembly is provided at the bottom of the diversion pipe. The compression chamber assembly includes a compression barrel provided at the bottom of the diversion pipe and communicating with the diversion pipe, so that the pollutants in the diversion pipe flow into the compression barrel. There is an installation hole on the left side of the compression barrel, and a cylinder is installed outside the installation hole. A compression plate for compressing the pollutants is slidably connected inside the linkage member. The compression plate is connected to the cylinder. There is a connection port on the right side of the compression barrel, and a compression cover is rotatably connected outside the connection port. During compression, the compression cover blocks the pollutants. The upper end of the compression cover is rotatably connected to the upper part of the compression barrel, and the lower end of the compression cover is locked to the bottom of the compression barrel through an elastic locking member. A linkage member is also provided outside the compression barrel to drive the compression cover to open or close. The linkage member passes through the installation hole in the compression barrel and is fixedly connected to the compression plate. The top end of the linkage member is rotatably connected to a driving arm. A chute is provided on the side of the driving arm away from the linkage member. The top end of the compression cover is slidably connected to the chute. An extrusion groove is provided inside the compression cover, and a resilient push shaft is elastically connected to the outer wall of the extrusion groove. One end of the resilient push shaft penetrates into the extrusion groove to form a push plate, and the other end of the resilient push shaft can contact the outer wall of the filtration pipeline. When the resilient push shaft contacts the outer wall of the filtration pipeline, the push plate at the top of the resilient push shaft pushes the pollutants in the extrusion groove out. A guide platform is provided on the outer wall of the water tank close to the compression cover to control the discharge direction of the compressed pollutants in the compression chamber assembly.

[0016] Furthermore, the specific structure of the elastic locking member includes a convex pin provided at the bottom of the compression barrel and an elastic pin that forms a snap connection with the convex pin. The elastic pin is elastically connected to the compression cover. The bottom of the elastic pin passes through the compression cover to form an unlocking rod. There is an unlocking plate at the bottom of the driving arm near the compression cover. When the unlocking plate moves towards the cylinder, the unlocking plate presses down the unlocking rod, causing the elastic pin to release the locking relationship with the convex pin.

[0017] In summary, the beneficial effects of the present invention are as follows:

[0018] 1. When the present invention clears floating objects in water, the floating object filter plate is driven by a motor to move towards the flow guide cover to filter pollutants floating in the wastewater. Under the resistance of the blocking posts, the floating object filter plate always remains vertical during the movement. When the floating object filter plate moves to a position close to the flow guide cover, the floating object filter plate is rotated clockwise to an inclined state through the one-way rotation assembly, and the floating objects in the water flow into the flow guide cover; the filter screen in the transmission filter pipeline filters the wastewater, and the spiral guide rod in the transmission filter pipeline conveys the filtered pollutants into the guide pipe. This structure does not require workers to manually fish for pollutants in the sewage during use, reducing the number of operators and the labor cost.

[0019] 2. The cylinder in the compression chamber assembly drives the compression plate to compress the pollutants. After the pollutants are squeezed into the extrusion groove in the compression cover, the elastic push shaft contacts the outer wall of the filter pipeline to push out the pollutants in the extrusion groove. This structure completes the compression work of the pollutants and effectively reduces the occupied space of the filtered pollutants during storage or transportation.

[0020] 3. The present invention can add decontamination agents into the water tank through the chemical agent adding barrel. The stirring structure in the water tank enables the decontamination agents to be fully mixed with the sewage to react, further removing other pollutants in the sewage, and achieving the effect of zero discharge of industrial wastewater.

Detailed implementation manners

[0030] The present invention will be further described below in conjunction with specific embodiments. The schematic embodiments and descriptions herein are used to explain the present invention, but not to limit the present invention.

[0031] Embodiment: An industrial wastewater zero-discharge treatment device as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 .

[0032] Refer to Figure 1As shown in the figure, the first embodiment of the present invention discloses an industrial wastewater zero-discharge treatment device, which includes a wastewater tank 1 for placing wastewater. There is a feeding port at the top of the wastewater tank 1, and a flow guide cover 201 is arranged on the outer wall of one side of the feeding port. The upper end of the flow guide cover 201 is communicated with the above-mentioned feeding port. A floating matter filter plate 6 is arranged on the inner wall of the feeding port in the direction away from the flow guide cover 201. The floating matter filter plate 6 forms a longitudinally slidable connection with the inner wall of the flow guide cover 201. The floating matter on the upper part of the wastewater is removed by the floating matter filter plate 6. A one-way rotation assembly is arranged at the end of the floating matter filter plate 6. After the floating matter filter plate 6 moves to a position close to the flow guide cover 201, the floating matter filter plate 6 is controlled to rotate towards the flow guide cover 201 through the one-way rotation assembly, so that the floating matter floating on the upper part of the wastewater tank 1 slides along the outer wall of the floating matter filter plate 6 into the flow guide cover 201. A screw rod 801 for driving the floating matter filter plate 6 to move on the inner wall of the wastewater tank 1 is rotatably connected to the outer side of the side wall of the wastewater tank 1. An electric motor 802 for driving the screw rod 801 to rotate is fixedly installed outside the wastewater tank 1. The screw rod 801 is connected with the electric motor 802 through a synchronous belt. The above-mentioned one-way rotation assembly is threadedly connected with the screw rod 801. A water tank 4 is arranged at the bottom of the wastewater tank 1. A transmission and filtration pipeline for filtering and conveying the sediment in the wastewater is arranged between the wastewater tank 1 and the water tank 4. A cylindrical guide pipe 202 extends downward from the bottom of the flow guide cover 201. The transmission and filtration pipeline is communicated with the guide pipe 202.

[0033] Refer to Figure 1 - Figure 2As shown, the one-way rotation assembly includes a driving seat 703, which is threadedly connected with the screw 801. A connecting shaft is provided at the upper end of the floating object filter plate 6, which passes through the driving seat 703 and is rotatably connected with the driving seat 703. A second driving plate 708 and a first driving plate 702 are provided on the connecting shaft at the top of the floating object filter plate 6. The second driving plate 708 is arranged on the inner side of the driving seat 703, and the first driving plate 702 is arranged on the outer side of the driving seat 703. A side baffle plate 709 is provided on the upper part of the side wall of the wastewater tank 1, and the floating object filter plate 6 is placed in a vertical state by making the side baffle plate 709 and the second driving plate 708 contact each other. A blocking column 707 is provided on the side of the driving seat 703, and the blocking column 707 is located at the lower end of the first driving plate 702. When the floating object filter plate 6 is moved forward, the first driving plate 702 and the blocking column 707 are contacted with each other to prevent the floating object filter plate 6 from moving in the opposite direction under the resistance of water and pollutants. An elastic connecting pin 704 is slidably provided on the side of the driving seat 703, and a connecting ring is fixedly provided around the elastic connecting pin 704. An elastic element is provided between the connecting ring and the driving seat 703. A positioning hole is provided on the connecting shaft at the top of the floating object filter plate 6. Under the elastic force of the above-mentioned elastic element, the elastic connecting pin 704 can be inserted into the positioning hole of the connecting shaft at the top of the floating object filter plate 6, so that the floating object filter plate 6 can maintain a tilted state, thereby preventing the floating object filter plate 6 from reversely filtering the floating objects in the wastewater. An unlocking transverse plate 706 is fixedly provided on the side of the side baffle 709 and extends outward. A through groove with an opening on one side is formed on the upper part of the unlocking transverse plate 706. The bottom of the open end of the through groove has a guide slope inclined downward. The elastic connecting pin 704 moves and the elastic connecting pin 704 can move into the through groove in the unlocking transverse plate 706. When the floating object filter plate 6 moves in the opposite direction after removing the floating pollutants in the wastewater, the elastic connecting pin 704 moves into the through groove in the unlocking transverse plate 706. Under the resistance of the guide slope in the unlocking transverse plate 706, the connecting ring in the elastic connecting pin 704 moves to the bottom of the unlocking transverse plate 706, and then the upper end of the elastic connecting pin 704 moves downward out of the positioning hole of the connecting shaft in the floating object filter plate 6, so that the floating object filter plate 6 can be rotated to a vertical state.

[0034] Reference Figure 3 - Figure 4As shown in the figure, a bogie 705 is provided at one end of the outer side wall of the wastewater tank 1 close to the guide hood 201. The top of the bogie 705 has a guide plate. A second guide inclined surface is provided on the side of the guide plate away from the guide hood 201. The guide plate on the top of the bogie 705 corresponds to the position of the first drive plate 702. When the floating object filter plate 6 moves towards the guide hood 201 for cleaning the floating objects, under the resistance of the guide plate on the top of the bogie 705, the top of the first drive plate 702 rotates in the reverse direction. At this time, the elastic connection pin 704 is engaged in the positioning hole of the connecting shaft at the top of the floating object filter plate 6 under the elastic force of the elastic element at the bottom, so as to fix the inclination angle of the floating object filter plate 6, and make the floating objects on the floating object filter plate 6 flow into the guide hood 201.

[0035] When the present invention removes the floating objects in the water, the motor 802 drives the floating object filter plate 6 to move towards the guide hood 201. Under the resistance of the stop post 707, the floating object filter plate 6 always maintains a vertical state during the movement. When the floating object filter plate 6 moves to a position close to the guide hood 201, the guide plate on the top of the bogie 705 contacts the first drive plate 702, making the floating object filter plate 6 rotate clockwise to an inclined state. At this time, the bottom of the floating object filter plate 6 is at a position close to the water surface. At the same time, the top of the elastic connection pin 704 is engaged in the positioning hole of the connecting shaft at the top of the floating object filter plate 6, so as to fix the inclination angle of the floating object filter plate 6. When the floating object filter plate 6 moves to the upper part of the guide hood 201, the floating object filter plate 6 makes the floating objects in the water flow into the guide hood 201. When the floating object filter plate 6 moves in the reverse direction after cleaning the floating objects on the water surface, because the surface of the floating object filter plate 6 is in an inclined state and the bottom of the floating object filter plate 6 is at a position close to the water surface, it will not perform reverse filtration on the floating objects in the wastewater; when the elastic connection pin 704 moves into the through groove in the unlocking cross plate 706, under the resistance of the bottom of the unlocking cross plate 706, the elastic connection pin 704 moves downward and releases the engagement and fixing relationship with the floating object filter plate 6. Subsequently, under the resistance of the side baffle 709, the floating object filter plate 6 returns to the vertical state. Repeating the above actions can effectively remove the pollutants floating on the wastewater surface. This structure does not require workers to fish for the floating pollutants during use, effectively reducing the number of operators.

[0036] Refer to Figure 6As shown, the specific structure of the transfer filtration pipeline includes a filtration pipeline 905 and a spiral guide rod 903. One end of the filtration pipeline 905 is connected to the diversion pipe 202, and the other end of the filtration pipeline 905 is connected to the wastewater tank 1. The connection end of the filtration pipeline 905 and the diversion pipe 202 is higher than the connection end of the filtration pipeline 905 and the wastewater tank 1, so that the wastewater in the filtration pipeline 905 flows into the wastewater tank 1. A valve for restricting the flow rate is provided between the filtration pipeline 905 and the wastewater tank 1. A filter screen 901 is provided at the bottom of the filtration pipeline 905. The above-mentioned filter screen 901 is connected to the water tank 4, and the filtered wastewater flows into the water tank 4 through the filter screen 901. A spiral guide rod 903 for driving the pollutants in the filtration pipeline 905 to move into the diversion pipe 202 is rotatably connected in the filtration pipeline 905. One end of the coupling 902 is connected to the filtration pipeline 905 on the side of the filtration pipeline 905 away from the diversion pipe 202. The other end of the coupling 902 is connected to the linkage shaft 904, and the linkage shaft 904 is connected to the motor 802 through a synchronous belt. During use, the pollutants in the wastewater are filtered by the filter screen 901 in the filtration pipeline 905, and the spiral guide rod 903 is driven to rotate by the motor 802 to transfer the pollutants in the filtration pipeline 905 into the diversion pipe 202. This structure does not require workers to manually fish out the pollutants in the wastewater during use, further reducing the number of operators.

[0037] Referring to Figure 5 As shown, there is a chemical dosing tank 5 for adding decontamination chemicals outside the water tank 4. The chemical dosing tank 5 is connected to the water tank 4. An internal motor 41 is provided at the upper end inside the water tank 4, and a stirring structure 42 is connected to the bottom of the internal motor 41. During use, the internal motor 41 drives the stirring structure 42 to rotate, so that the decontamination chemical and the wastewater can be fully mixed and react to further remove other pollutants in the wastewater. An outlet 401 is provided at the upper position near the bottom of the water tank 4, and a sediment discharge port 402 is provided at the bottom of the water tank 4. The purified water after being purified by the decontamination chemical is discharged outwards through the outlet 401, and the sediment generated after the wastewater reacts with the decontamination chemical is discharged outwards through the sediment discharge port 402. Valves for restricting the flow rate are provided on both the outlet 401 and the sediment discharge port 402. This structure enables the industrial wastewater to meet the design requirement of zero discharge.

[0038] The present invention proposes a second embodiment. Referring to Figure 6 and Figure 7As shown in the figure, a compression chamber assembly is provided at the bottom of the diversion pipe 202. The compression chamber assembly includes a compression barrel 301 provided at the bottom of the diversion pipe 202 and communicating with the diversion pipe 202, so that the pollutants in the diversion pipe 202 flow into the compression barrel 301. The left side of the compression barrel 301 has a mounting hole, and a cylinder 302 is installed outside the mounting hole. A compression plate 305 for compressing pollutants is slidably connected inside the linkage 303. Therefore, the compression plate 305 is connected to the cylinder 302. The right side of the compression barrel 301 has a connection port, and a compression cover 306 is rotatably connected outside the connection port. When compressing, the pollutants are blocked by the compression cover 306. The upper end of the compression cover 306 is rotatably connected to the upper part of the compression barrel 301, and the lower end of the compression cover 306 is locked to the bottom of the compression barrel 301 through an elastic locking member. A linkage 303 is further provided outside the compression barrel 301 to drive the compression cover 306 to open or close through the linkage 303. The linkage 303 passes through the mounting hole in the compression barrel 301 and is fixedly connected to the compression plate 305. The top end of the linkage 303 is rotatably connected to a driving arm 308. A chute is provided on the side of the driving arm 308 away from the linkage 303. The top end of the compression cover 306 is slidably connected to the above chute. An extrusion groove is provided inside the compression cover 306. A resilient push shaft 313 is elastically connected to the outer wall of the extrusion groove. After one end of the resilient push shaft 313 penetrates into the extrusion groove, a push plate is formed. The other end of the resilient push shaft 313 can contact the outer wall of the filter pipe 905. When the resilient push shaft 313 contacts the outer wall of the filter pipe 905, the push plate at the top of the resilient push shaft 313 pushes out the pollutants in the extrusion groove. A guiding platform 304 is provided on the outer wall of the water tank 4 near the compression cover 306 to control the discharge direction of the compressed pollutants in the compression chamber assembly.

[0039] Refer to Figure 8 As shown in the figure, preferably, the specific structure of the elastic locking member includes a convex pin 309 provided at the bottom of the compression barrel 301 and a resilient pin 310 that is snap-fitted with the convex pin 309. The resilient pin 310 is elastically connected to the compression cover 306. The bottom of the resilient pin 310 passes through the compression cover 306 to form an unlocking rod 311. An unlocking plate 312 is provided at the bottom of the driving arm 308 near the compression cover 306. When the unlocking plate 312 moves towards the cylinder 302, the unlocking plate 312 presses down the unlocking rod 311, so that the resilient pin 310 is disengaged from the convex pin 309.

[0040] When using the present invention for pollutant compression, the compression plate 305 is driven by the cylinder 302 to extrude towards the compression cover 306. The compression plate 305 drives the linkage 303 to move towards the compression cover 306. Under the traction force of the driving arm 308, the compression cover 306 rotates downward around the connection end of the compression cover 306 and the compression barrel 301, and covers the connection port of the compression barrel 301. At this time, the compression cover 306 and the compression barrel 301 are locked and connected through the elastic locking member. After the pollutants are extruded into the extrusion groove in the compression cover 306, the cylinder 302 drives the compression plate 305 to move in the opposite direction. The unlocking plate 312 presses down the unlocking rod 311 to release the locking relationship between the compression cover 306 and the compression barrel 301. Under the traction force of the driving arm 308, the compression cover 306 rotates upward around the connection end of the compression cover 306 and the compression barrel 301, so that the elastic push shaft 313 contacts the outer wall of the filter pipe 905 to push out the pollutants in the extrusion groove. This structure effectively reduces the occupied space of the filtered pollutants during storage or transportation.
