Description

Technical Field

[0001] The present invention mainly relates to the technical field of sewage treatment equipment, and specifically, it is an industrial wastewater treatment device. Background Art

[0002] With the rapid development of industries such as chemical engineering, pharmaceuticals, and printing and dyeing, the discharge of high-salt wastewater has increased sharply, becoming a major challenge in the current environmental protection field. High-salt wastewater not only contains high concentrations of salts (such as sodium chloride, sodium sulfate, etc.), but also often contains organic substances, heavy metals, and other pollutants. The presence of these substances makes the treatment of high-salt wastewater particularly complex and difficult.

[0003] The existing Chinese patent with the publication number CN112403041A discloses a sedimentation tank for wastewater treatment, including a base plate and support columns. The support columns are arranged at the top of the base plate and are fixed to the base plate by welding. A water tank is arranged at the top of the support columns and is fixedly connected to the support columns by welding. A drain port is arranged near the bottom end on the right side of the water tank. When the present invention is in use, it is necessary to first seal the flange surfaces at the drain port and the sewage discharge pipe, and then pour the wastewater to be sedimented into the water tank from the water inlet. After sedimentation is completed, the flange surface at the drain port is opened, and the sedimented water is discharged from the drain port. When the quantity of sediment is close to reaching the highest point of the inclined plate tank, the flange surface at the sewage discharge pipe is opened, and the sediment is discharged from the right end of the sewage discharge pipe for recycling. The filter screen can filter out some larger granular sediments before the wastewater enters the water tank to prevent the sediments from blocking the sewage discharge pipe and the sewage branch pipes.

[0004] However, the wastewater treatment device has the following defects in specific use: The design of sewage sedimentation tanks in the prior art generally tends to adopt the method of static sedimentation, that is, the sewage flows inside the sedimentation tank at a relatively constant and slow speed, and its flow direction also basically remains unchanged. Although this static sedimentation mode is easy to operate, it easily leads to a problem that cannot be ignored: excessive sludge accumulates in the end area in the flow direction of the sewage. Due to the consistency of the flow rate and direction, the sedimentation effect in the end area becomes particularly prominent, while the sedimentation effect in other areas is relatively weak, resulting in a certain gap between the overall sedimentation efficiency and the expected target, and the sedimentation effect is limited. Summary of the Invention

[0005] To solve the deficiencies of the prior art, the present invention provides an industrial wastewater treatment device, which is achieved through the following technical solutions: An industrial wastewater treatment device comprises a sedimentation tank, a water blocking plate, and a direction adjustment component, wherein a sludge tank is fixedly installed on one side of the bottom surface of the sedimentation tank, a sewage trough communicating with the sludge tank is opened on one side of the bottom surface of the inner wall of the sedimentation tank, a plurality of water blocking plates are rotatably installed in the middle of the sedimentation tank and are arranged in an inclined manner from top to bottom, and a direction adjustment component capable of driving the water blocking plates to rotate is provided in the sedimentation tank; Wherein, the direction adjustment component includes: A connecting plate, the connecting plate is installed in the sedimentation tank in a sliding manner, and the connecting plate is connected to the water blocking plate through a transmission assembly; A telescopic rod is fixedly installed at the rear of the sedimentation tank, and a movable end of the telescopic rod is fixedly connected to the rear of the connecting plate. Furthermore, a rotating shaft is fixedly installed on the front and rear of the water blocking plate, and the outer ends of the rotating shaft are respectively connected to the inner wall bearings of the sedimentation tank.

[0006] Furthermore, the transmission assembly includes: A mounting seat, wherein the mounting seat is fixedly mounted on the upper portion of the rear side of one side of the water blocking plate; A connecting rod is fixedly mounted on the rear of the mounting seat, and a plurality of inclined sliding grooves are provided on the front of the connecting plate, and the connecting rods are respectively inserted into corresponding sliding grooves and slidably matched therewith.

[0007] Furthermore, the telescopic rod is a waterproof hydraulic cylinder.

[0008] Furthermore, the interior of the sedimentation tank is stepped.

[0009] Furthermore, the inclination angle of the slide groove matches the inclination angle of the water blocking plate, ensuring that during the sliding of the connecting plate, the connecting rod can move smoothly along the slide groove, thereby driving the water blocking plate to rotate at a predetermined angle, thereby optimizing the water flow guidance and sedimentation effect.

[0010] Furthermore, a sludge discharge device is provided on one side of the sludge pool. The automatic sludge discharge device includes a sludge pump and a conveying pipe connected to the sludge pump. One end of the conveying pipe extends into the bottom of the sludge pool, and the other end extends to the outside of the device, so as to facilitate regular cleaning of deposited sludge and maintain continuous and efficient operation of the treatment system.

[0011] Compared with the prior art, the beneficial effects of the present invention are: This device achieves effective collection and discharge of sludge by arranging a sludge pool and a sewage trough on one side of the bottom surface of the sedimentation tank, avoids the accumulation of sludge in the sedimentation tank, and ensures the continuous and efficient operation of the sedimentation tank. The introduction of the inclined water blocking plate and the direction adjustment component dynamically adjusts the water flow path, promotes the rapid sedimentation of suspended matter, and improves the purification efficiency of wastewater.

[0016] Embodiment: An industrial wastewater treatment device As Figures 1-6 shown, an industrial wastewater treatment device, its specific structure includes: A sedimentation tank 10, a water blocking plate 20, and a direction adjustment component 30. A sludge tank 40 is fixedly installed on one side of the bottom surface of the sedimentation tank 10. A sewage trough 101 communicating with the sludge tank 40 is opened on one side of the bottom surface of the inner wall of the sedimentation tank 10. A plurality of water blocking plates 20 are rotatably installed in the middle of the sedimentation tank 10 and are tilted sequentially from top to bottom. A direction adjustment component 30 capable of driving the water blocking plates 20 to rotate is provided in the sedimentation tank 10. Wherein, the direction adjustment component 30 includes: A connecting plate 301, wherein the connecting plate 301 is installed in the sedimentation tank 10 in a sliding manner, and the connecting plate 301 is connected to the water blocking plate 20 through a transmission assembly 50 to achieve a linkage effect; The telescopic rod 302 is fixedly installed at the rear of the sedimentation tank 10, the movable end of the telescopic rod 302 is fixedly connected to the rear of the connecting plate 301, an extension plate is fixedly installed at the rear of the connecting plate 301, and the movable end of the telescopic rod 302 is fixedly connected to the bottom surface of the extension plate. The above works like this: When the device performs pre-sedimentation treatment of sewage, the sewage to be treated is injected from the right side of the sedimentation tank 10, and the precipitated sewage is sucked out from the left side thereof through a pipe. During the sewage sedimentation process, the device can change the direction of the water flow by adjusting the direction of the water blocking plate 20 to promote the sedimentation of suspended matter so as to dynamically adjust the water flow path and improve the sedimentation efficiency; through the extension and retraction of the telescopic rod 302, the connecting plate 301 slides in the sedimentation tank 10, driving the water blocking plate 20 to rotate around the rotating shaft 201 as the center, and changing the water flow path through the water blocking plate 20, promotes the suspended matter to settle to the bottom faster, thereby improving the wastewater purification efficiency and reducing energy consumption at the same time.

[0017] The front and rear of the water blocking plate 20 are respectively fixedly mounted with a rotating shaft 201, and the outer ends of the rotating shaft 201 are respectively connected to the inner wall bearings of the sedimentation tank 10. The water blocking plate 20 is connected to the inner wall bearings of the sedimentation tank 10 through the front and rear rotating shafts 201 to ensure that it can rotate smoothly under the action of the direction adjustment component 30, which not only ensures the stability of the structure, but also facilitates the adjustment of the water flow direction and optimizes the sedimentation process.

[0018] The transmission assembly 50 includes: a mounting base 501 fixedly installed on the upper part of the rear side of one side of the water-blocking plate 20; a connecting rod 502 fixedly installed on the rear side of the mounting base 501, and a plurality of inclined chutes 303 are formed on the front surface of the connecting plate 301. The number of the chutes 303 is the same as and corresponds to the number of the connecting rods 502 one by one. The connecting rods 502 are respectively inserted into the corresponding chutes 303 and are in sliding fit with them. The transmission assembly 50 is in sliding fit with the chutes 303 on the connecting plate 301 through the mounting base 501 and the connecting rods 502. When the connecting plate 301 moves, the connecting rods 502 slide in the chutes 303 to drive the water-blocking plate 20 to rotate. This design has a simple structure, high transmission efficiency, and is easy to maintain.

[0019] The telescopic rod 302 is a waterproof hydraulic cylinder, which can ensure stable operation in a humid environment, is not eroded by moisture, extends the service life, and at the same time provides a stable driving force to ensure the accuracy and reliability of direction adjustment.

[0020] The interior of the sedimentation tank 10 is stepped. This structural design is conducive to slowing down the water flow speed during the flow process, increasing the chance of suspended matter sedimentation, improving the sedimentation efficiency, and at the same time facilitating the subsequent collection and treatment of sludge.

[0021] The inclination angle of the chute 303 matches the inclination angle of the water-blocking plate 20, ensuring that during the sliding process of the connecting plate 301, the connecting rod 502 can move smoothly along the chute 303, thereby driving the water-blocking plate 20 to rotate at a predetermined angle, optimizing the water flow guidance and sedimentation effect. This structural design optimizes the water flow guidance, improves the sedimentation effect, and ensures the stability and high efficiency of wastewater treatment.

[0022] A sludge discharging device 60 is provided on one side of the sludge tank 40. The automatic sludge discharging device 60 includes a sludge pump 601 and a conveying pipeline 602 connected to the sludge pump 601. One end of the conveying pipeline 602 extends into the bottom of the sludge tank 40, and the other end extends to the outside of the device. The deposited sludge is regularly discharged through the sludge pump 601 and the conveying pipeline 602, avoiding the problems of reduced treatment efficiency and blockage caused by sludge accumulation, maintaining the continuous and efficient operation of the treatment system, and reducing the frequency and difficulty of manual cleaning.

[0023] This solution also includes a controller, whose position is set according to the actual situation by the staff during operation.
