Description

Technical Field

[0001] This utility model belongs to the field of petrochemical technology, specifically relating to a petrochemical wastewater treatment device. Background Technology

[0002] Currently, filtration is a commonly used pretreatment method in petrochemical wastewater treatment, mainly using filter media to intercept suspended solids and some impurities in the wastewater. Traditional filtration devices typically use fixed filter plates or screens, such as plate and frame filter presses and sand filters.

[0003] However, these traditional filtration devices have significant shortcomings. As the filtration process continues, a large amount of impurities gradually accumulate on the surface of the filter plates or screens, leading to increased filtration resistance and decreased filtration efficiency. To restore filtration performance, frequent backwashing or replacement of the filter media is required, which not only increases operating costs but also affects the continuity and stability of wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to provide a petrochemical wastewater treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A petrochemical wastewater treatment device includes a filter tank and a treatment tank. The filter tank is located above the treatment tank. An inlet pipe is provided on the upper left side of the filter tank. The lower side of the filter tank is connected to the treatment tank through a pipe. A filtration mechanism is provided inside the filter tank.

[0007] The filtration mechanism includes a circular shell rotatably mounted in the middle of the filter tank. Several rotating shafts are rotatably mounted on the side wall of the circular shell. Each of the rotating shafts has a fan-shaped filter plate fixed at its end. The fan-shaped filter plates together form a circular filter plate.

[0008] A rectangular shell is fixed inside the circular shell. A rectangular plate is slidably disposed inside the rectangular shell. A first spring is disposed between the rectangular plate and the rectangular shell. A circular rod is fixed to one side of the rectangular plate. A circular groove matching the circular rod is opened on the rotating shaft. A spiral groove is opened on the side wall of the circular groove. A guide block matching the spiral groove is fixed to the circular rod. A push rod is fixed to the other side of the rectangular plate. A circular block located in the middle of the circular shell is fixed to the filter tank. The push rod abuts against the circular block. A protrusion is fixed to the right side of the circular block.

[0009] A rotating rod is fixed to the upper end of the circular shell. The rotating rod is rotatably mounted on the upper wall inside the filter tank. A motor is installed at the upper end of the filter tank, and the output shaft of the motor is connected to the rotating rod for transmission.

[0010] A fixing rod is fixed to the bottom of the filter tank, and the circular block is fixed to the upper end of the fixing rod.

[0011] A collection box is provided on the bottom right side of the filter tank.

[0012] The fan-shaped filter plate is composed of a fan-shaped frame and a fan-shaped filter screen. The fan-shaped frame is fixed to the rotating shaft. A second spring is provided at the bottom of the fan-shaped frame. The fan-shaped filter screen slides inside the fan-shaped frame and is connected to the upper end of the second spring.

[0013] By incorporating rectangular shells, rectangular plates, and circular rods within a circular shell, along with circular and spiral grooves on the rotating shaft, and a circular block with protrusions fixed inside the filter tank, this design achieves automatic cleaning of impurities from the filter plate. When the fan-shaped filter plate, which intercepts impurities on the left, rotates to the right, the push rod abuts against the protrusion, causing the circular rod to slide into the circular groove. The guide block slides within the spiral groove, causing the rotating shaft to rotate, which in turn causes the fan-shaped filter plate to flip into a vertical position, allowing impurities to fall downwards. This design requires no manual intervention and can automatically clean impurities from the filter plate, effectively preventing impurities from clogging the filter plate and ensuring filtration effect and efficiency.

Detailed Implementation

[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-4 As shown, a petrochemical wastewater treatment device of the present invention includes a filter tank 1 and a treatment tank 11. The filter tank 1 is located above the treatment tank 11. An inlet pipe 101 is provided on the upper left side of the filter tank 1. The lower side of the filter tank 1 is connected to the treatment tank 11 through a pipe. A filtration mechanism is provided inside the filter tank 1.

[0023] The filtration mechanism includes a circular shell 2 rotatably installed in the middle of the filter tank 1. Several rotating shafts 21 are rotatably installed on the side wall of the circular shell 2. Each of the rotating shafts 21 has a fan-shaped filter plate 22 fixed at its end. The fan-shaped filter plates 22 together form a circular filter plate.

[0024] A rectangular shell 23 is fixed inside a circular shell 2. A rectangular plate 231 is slidably disposed inside the rectangular shell 23. A first spring 232 is disposed between the rectangular plate 231 and the rectangular shell 23. A circular rod 233 is fixed on one side of the rectangular plate 231. A circular groove 211 matching the circular rod 233 is opened on the rotating shaft 21. A spiral groove 212 is opened on the side wall of the circular groove 211. A guide block matching the spiral groove 212 is fixed on the circular rod 233. A push rod 235 is fixed on the other side of the rectangular plate 231. A circular block 236 located in the middle of the circular shell 2 is fixed on the filter tank 1. The push rod 235 abuts against the circular block 236. A protrusion 237 is fixed on the right side of the circular block 236.

[0025] A rotating rod 201 is fixed to the upper end of the circular shell 2. The rotating rod 201 is rotatably installed on the upper wall of the filter tank 1. A motor 202 is installed at the upper end of the filter tank 1. The output shaft of the motor 202 is connected to the rotating rod 201 for transmission.

[0026] After the push rod 235 abuts against the protrusion 237, it can drive the circular rod 233 to slide into the circular groove 211 through the rectangular plate 231. Then the guide block slides in the spiral groove 212, causing the rotating shaft 21 to rotate, which in turn drives the fan-shaped filter plate 22 to flip into a vertical state.

[0027] Therefore, the fan-shaped filter plates 22 on the left are horizontal, while the fan-shaped filter plates 22 on the right are vertical.

[0028] When treating wastewater, the wastewater enters the filter tank 1 through the inlet pipe 101. Impurities in the wastewater are intercepted by the fan-shaped filter plates 22 and remain on the upper side of the fan-shaped filter plates 22. Then, the wastewater enters the treatment tank 11 through the pipeline for further treatment. When filtering wastewater, the motor 202 is started. The motor 202 drives the circular shell 2 to rotate through the rotating rod 201, which in turn drives several fan-shaped filter plates 22 to rotate. When the fan-shaped filter plate 22 with impurities intercepted on the left rotates to the right, the push rod 235 abuts against the protrusion 237, and the fan-shaped filter plate 22 will flip to a vertical state, and the impurities will fall downwards. In this way, as the fan-shaped filter plates 22 continue to rotate, impurities can be prevented from clogging the fan-shaped filter plates 22, and the fan-shaped filter plates 22 can be automatically cleaned.

[0029] A fixing rod 238 is fixed at the bottom of the filter tank 1, and a circular block 236 is fixed at the upper end of the fixing rod 238; the circular block 236 is fixed inside the filter tank 1 by the fixing rod 238.

[0030] A collection box 3 is provided on the bottom right side of the filter tank 1; the collection box 3 is used to collect the impurities filtered by the fan-shaped filter plate 22.

[0031] The sector-shaped filter plate 22 is composed of a sector-shaped frame 221 and a sector-shaped filter screen 222. The sector-shaped frame 221 is fixed to the rotating shaft 21. A second spring 223 is provided at the bottom of the sector-shaped frame 221. The sector-shaped filter screen 222 slides inside the sector-shaped frame 221 and is connected to the upper end of the second spring 223.

[0032] The fan-shaped filter screen 22 slides within the fan-shaped frame 221 via the second spring 223, making it elastically connected. When the fan-shaped frame 221 is flipped, the fan-shaped filter screen 22 can vibrate slightly, shaking off impurities.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
