Description

Technical Field

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

[0002] The production of oils and fats inevitably generates a large amount of wastewater. Since the wastewater contains many substances that are harmful to the environment, direct discharge will cause water pollution and pollute the surrounding environment. Therefore, enterprises need to treat the wastewater to meet environmental protection requirements before it can be discharged.

[0003] Patent application CN202420404196.X discloses a wastewater treatment device for vegetable oil processing, comprising a first chamber, two support seats fixedly connected to the top outer wall of the first chamber, a second chamber fixedly connected to the top of the two support seats, movable plates slidably inserted into both sides of the second chamber, and a shell fixedly connected to both sides of the second chamber, with the movable plates sliding within the shell. A first electric push rod is fixedly connected to both sides of the second chamber, one end of which passes through the second chamber and is fixedly connected to the movable plate. A stand is fixedly connected to the top outer wall of the second chamber, with a second electric push rod fixedly connected to the top of the stand. Driven by the extension of the first electric push rod, the movable plates slide within the shell, causing the two movable plates to converge towards the center, thereby sealing the upper part of the second chamber, facilitating wastewater settling and improving oil removal efficiency. However, the above-mentioned device has some problems. For example, the filter screen and activated carbon layer are inconvenient to replace, which is not conducive to later maintenance. In addition, the discharge of flocculent matter such as waste residue in the filtered wastewater is very inconvenient, and the removal of floating oil is also inconvenient, which affects the operating efficiency of the equipment. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a wastewater treatment device for oil processing.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A wastewater treatment device for oil processing includes a treatment tank, a baffle assembly, and a piston pusher assembly. The treatment tank has a bottom plate at its lower end and a top cover at its upper end. The baffle assembly includes a fixed baffle that is horizontally fixed to the center of the treatment tank. The area above the fixed baffle is a filtration zone, and the area below the fixed baffle is a settling zone. A vertically upward mounting cylinder is located at the center of the upper surface of the fixed baffle, and an activated carbon filter cylinder is mounted on the mounting cylinder. The piston pusher assembly includes a fixed circular plate that is fixedly mounted between the bottom plate and the fixed baffle. A vertically positioned guide post is provided between the fixed circular plate and the fixed baffle. A cylinder assembly is located at the center of the fixed circular plate, and a piston pusher assembly is fixedly connected to the upper end of the cylinder assembly. The piston pusher assembly is slidably and sealingly connected to the inner wall of the treatment tank and sealingly connected to the guide post. A vertically upward scraper assembly is located at the center of the upper end of the piston pusher assembly.

[0007] As a further provision of the above scheme, the treatment tank is equipped with a water inlet device, a drainage device, and a sewage discharge device. The water inlet device and the sewage discharge device are located below the fixed partition, the sewage discharge device is located above the water inlet device, and the drainage device is located above the fixed partition.

[0008] As a further feature of the above scheme, the lower end face of the fixed partition is provided with a guide conical groove, which is connected to the mounting cylinder. The mounting cylinder is provided with evenly distributed through holes, and an oil collecting cylinder is provided at the upper end of the mounting cylinder. The oil collecting cylinder extends upward beyond the top cover, and an oil discharge device is provided at the center of the upper end of the oil collecting cylinder. A concentric mounting retaining ring is provided at the lower end of the mounting cylinder.

[0009] As a further feature of the above solution, the upper end of the activated carbon filter cylinder is provided with a limiting platform, the activated carbon filter cylinder is slidably connected to the mounting cylinder, the lower end of the activated carbon filter cylinder is sealed and engaged with the mounting retaining ring, and the limiting platform is sealed and engaged with the upper cover.

[0010] As a further feature of the above scheme, a frustum is provided on the upper surface of the piston pusher, the frustum being able to be sealed and engaged with the guide conical groove, and the scraper device includes a telescopic rod device, the lower end of which is fixedly installed at the center of the frustum, and a circular scraper connected to the upper end of which is able to slide and connect with the inner wall of the mounting cylinder.

[0011] This utility model has the following beneficial effects:

[0012] Wastewater and treatment agent are added to the treatment tank through the inlet device. After settling, the cylinder device drives the piston pusher to rise, pushing the floating oil on the surface of the wastewater into the installation cylinder. The circular scraper immediately enters the installation cylinder to isolate the floating oil from the wastewater. The piston pusher continues to rise, and the wastewater passes through the installation cylinder and activated carbon filter cylinder before entering the upper part of the fixed baffle. After filtration, the wastewater is discharged from the drainage device, and the floating oil is automatically discharged from the oil discharge device. Waste residue and other flocculent matter in the wastewater are trapped in the installation cylinder. When the piston pusher descends, the circular scraper drives the waste residue and other flocculent matter to descend synchronously, and finally discharges them from the sewage discharge device. This achieves automatic discharge of waste residue and other flocculent matter and convenient removal of floating oil, greatly improving wastewater treatment efficiency.

[0013] The circular scraper automatically cleans the inner wall of the installation cylinder, and the activated carbon filter cartridge can be easily installed and removed from the installation cylinder, making the later maintenance of the equipment very convenient, reducing equipment maintenance costs, and improving equipment operating efficiency.

The piston pusher... The device 6 includes a fixed circular plate 601, which is fixedly installed between the base plate 2 and the fixed partition plate 401. A vertically arranged guide post 6011 is provided between the fixed circular plate 601 and the fixed partition plate 401. A cylinder device 602 is provided at the center of the fixed circular plate 601. A piston pusher 603 is fixedly connected to the upper end of the cylinder device 602. The piston pusher 603 is slidably and sealingly connected to the inner wall of the processing tank 1. The piston pusher 603 is sealed to the guide post 6011. A vertically upward scraper device 7 is provided at the center of the upper end of the piston pusher 603.

[0023] like Figure 1 As shown, the treatment tank 1 is equipped with a water inlet device 8, a drainage device 9 and a sewage discharge device 10. The water inlet device 8 and the sewage discharge device 10 are located below the fixed partition 401, the sewage discharge device 10 is located above the water inlet device 8, and the drainage device 9 is located above the fixed partition 401.

[0024] like Figure 2 , Figure 3 , Figure 4As shown, a guide conical groove 4011 is opened on the lower end face of the fixed partition 401. The guide conical groove 4011 is connected to the mounting cylinder 402. The mounting cylinder 402 has evenly distributed through holes 4021. An oil collecting cylinder 4022 is provided at the upper end of the mounting cylinder 402. The oil collecting cylinder 4022 protrudes upward from the upper cover 3. An oil discharge device 4023 is provided at the center of the upper end of the oil collecting cylinder 4022. A concentric mounting retaining ring 403 is provided at the lower end of the mounting cylinder 402. A limiting platform 501 is provided at the upper end of the activated carbon filter cylinder 5. The activated carbon filter cylinder 5 is slidably connected to the mounting cylinder 402. The lower end of the activated carbon filter cylinder 5 is sealed and engaged with the mounting retaining ring 403. The limiting platform 501 is sealed and engaged with the upper cover 3.

[0025] like Figure 5 As shown, a frustum 6031 is provided on the upper surface of the piston pusher 603. The frustum 6031 can be sealed and engaged with the guide cone groove 4011. The scraper device 7 includes a telescopic rod device 701. The lower end of the telescopic rod device 701 is fixedly installed at the center of the frustum 6031. A circular scraper 702 is connected to the upper end of the telescopic rod device 701. The circular scraper 702 can be slidably connected with the inner wall of the mounting cylinder 402.

[0026] The working process of this utility model is as follows: First, sewage and treatment agent are added to the settling area through the inlet device. After the sewage undergoes settling and other treatment processes (other treatment devices are not shown in the figure), the cylinder device 602 is activated, driving the piston pusher 603 to rise under the guidance of the guide column 6011. The floating oil on the upper layer of sewage first enters the mounting cylinder 402. When the floating oil enters the mounting cylinder 402, the telescopic rod device 701 adjusts the height of the circular scraper 702. The circular scraper 702 immediately enters the mounting cylinder 402 to isolate the floating oil from the lower layer of sewage. The piston pusher 603 continues to rise, and the lower layer of sewage enters the mounting cylinder 402. At the same time, the sewage is pressurized and passes through the through hole 4021 on the mounting cylinder 402 and is filtered by the activated carbon filter cylinder 5. Upon entering the filtration zone, after the frustum 6031 engages with the guide cone groove 4011, the telescopic rod device 701 first drives the circular scraper 702 into the oil collection cylinder 4022, automatically discharging the floating oil from the oil discharge device 4023. After the floating oil is discharged, the telescopic rod device 701 drives the circular scraper 702 to descend, further squeezing and filtering the wastewater in the installation cylinder 402, concentrating the wastewater in the installation cylinder 402. Simultaneously, the filtered wastewater is discharged from the drainage device 9, while the waste residue and other flocculent matter in the water are trapped in the oil collection cylinder 402. The piston pusher 603 continues to descend, and the circular scraper 702 drives the waste residue and other flocculent matter to descend synchronously. The waste residue and other flocculent matter automatically flow back to the settling area and are finally automatically discharged from the sewage discharge device 10 under the guidance of the frustum 6031.

[0027] The water inlet device 8, the drainage device 9, the oil discharge device 4023, and the sewage discharge device 10 are automatically controlled to open and close according to the treatment process. They work together to complete the addition and discharge of sewage and the automatic discharge of flocculent materials such as waste residue. The activated carbon filter cartridge 5 is easy to disassemble and facilitates later maintenance.

[0028] The circular scraper 702 automatically cleans the inner wall of the mounting cylinder 402 to prevent clogging.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
