Description

Technical Field

[0001] This utility model belongs to the field of pretreatment technology for soybean peptone production wastewater, specifically relating to a multi-stage filtration device for pretreatment of soybean peptone production wastewater. Background Technology

[0002] Soy peptone is a high-quality protein source widely used in microbial culture medium preparation, food industry, and pharmaceuticals. The production process of soybean peptone generates a large amount of wastewater containing various impurities. Direct discharge of this wastewater without effective treatment will not only cause serious environmental pollution but also lead to a waste of water resources. Therefore, pretreatment of soybean peptone production wastewater to remove impurities is a crucial step in environmental protection and sustainable resource utilization.

[0003] In current pretreatment technologies for soybean peptone production wastewater, filtration is a common and important method. Traditional filtration methods often employ a single filter screen or filter cartridge. However, this single filtration structure has several drawbacks. On the one hand, because soybean peptone production wastewater has a complex composition containing impurities of varying particle sizes, a single filtration structure cannot effectively remove impurities of different particle sizes simultaneously, resulting in unsatisfactory filtration effects and failing to meet the requirements for subsequent wastewater treatment or reuse. On the other hand, during prolonged filtration, impurities easily accumulate on the surface of the filter screen or filter cartridge, causing blockage. Once blockage occurs, it not only reduces filtration efficiency and increases energy consumption, but also requires frequent replacement of the filter screen or filter cartridge, increasing treatment costs and maintenance workload.

[0004] To address these issues, some existing technologies attempt to pretreat soybean peptone production wastewater using multi-stage filtration devices. Some involve adding electrical components: mechanical scraper-type self-cleaning devices (such as drum filters) have limited effectiveness in removing adhesive impurities and are structurally complex; meanwhile, series-connected filtration equipment typically relies on independent power to drive each filter element, resulting in high energy consumption and low pressure differential transmission efficiency, making compact design difficult.

[0005] To address this issue, we propose a multi-stage filtration device for the pretreatment of soybean peptone production wastewater. This device utilizes wastewater pressure as the core driving force to achieve automatic extension and filtration of the filter rings and elastic reset for scraping and cleaning, effectively solving the problem of easy clogging of traditional static filter screens. Utility Model Content

[0006] The purpose of this invention is to provide a multi-stage filtration device for pretreatment of soybean peptone production wastewater. This device uses wastewater pressure as the core driving force to realize automatic extension and filtration of the filter ring and elastic reset for scraping and cleaning, effectively solving the problem of easy clogging of traditional static filter screens.

[0007] The specific technical solution adopted by this utility model is as follows:

[0008] A multi-stage filtration device for pretreatment of soybean peptone production wastewater includes a treatment cylinder. A telescopic component is provided on one side of the treatment cylinder. A first sealing slide and a second sealing slide are provided on the telescopic component, located inside the treatment cylinder. The first and second sealing slides divide the treatment cylinder into a first cavity, a second cavity, and a third cavity. Both the first and second sealing slides are arranged in a circular array with multiple first through holes, second through holes, and elastic components. A slider is slidably disposed inside the first through hole. A hollow cylindrical filter ring connected to the elastic component is provided on the top of the slider. A third through hole is opened on the slider and communicates with the hollow cavity of the hollow cylindrical filter ring. The third through hole communicates with the first through hole. A connecting rod is movably disposed inside the second through hole and fixedly connected to the inner wall of one side of the treatment cylinder. A removal rod located inside the hollow cylindrical filter ring is provided at the other end of the connecting rod.

[0009] Furthermore, the telescopic assembly includes an electrically operated telescopic rod disposed on the processing cylinder, the telescopic end of which is connected to the first sealing slide and the second sealing slide.

[0010] Furthermore, the diameter of the first through hole is larger than the diameter of the third through hole, and the diameter of the third through hole is larger than the diameter of the hollow cylindrical filter ring.

[0011] Furthermore, the elastic component includes a hollow cylinder disposed on the top of the first sealing slide and the second sealing slide. A spring is disposed inside the hollow cylinder, a piston disc is disposed on one side of the spring, and a movable rod is disposed on one side of the piston disc. The top of the movable rod extends through the hollow cylinder and is connected to the hollow cylindrical filter ring.

[0012] Furthermore, a discharge port is provided at the bottom of the processing cylinder, and a sealing plate is provided on the discharge port.

[0013] Furthermore, a cleaning brush is provided on the outside of the cleaning rod, and the cleaning brush is in contact with the filter surface of the hollow cylindrical filter ring.

[0014] Furthermore, a drain pipe is provided at the bottom of the processing cylinder.

[0015] The technical effects achieved by this utility model are as follows:

[0016] 1. When the telescopic assembly is activated, it moves the first and second sealing slides, squeezing the wastewater inside the first cavity. The resulting pressure acts on the first sealing slide, pushing the slider to extend the hollow cylindrical filter ring from the first through hole. The hollow cylindrical filter ring then stretches the elastic component, allowing the wastewater to pass through the filter ring and enter the second cavity. The wastewater entering the second cavity also creates a pressure difference, which acts on the second sealing slide, pushing the slider to extend the hollow cylindrical filter ring from the first through hole. The hollow cylindrical filter ring then stretches the elastic component, allowing the wastewater to pass through another hollow cylindrical filter ring and enter the third cavity. This multi-stage filtration process removes impurities from the wastewater.

[0017] 2. Then, the telescopic component is pulled in the opposite direction, the pressure disappears, and the elastic component drives the hollow cylindrical filter ring to make the slider enter the first through hole. At this time, when it enters, the hollow cylindrical filter ring moves on the impurity removal rod, thereby removing impurities on the filter surface of the hollow cylindrical filter ring and preventing clogging.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4As shown, a multi-stage filtration device for pretreatment of soybean peptone production wastewater includes a treatment cylinder 1. A telescopic component is provided on one side of the treatment cylinder 1. The telescopic component is provided with a first sealing slide 2 and a second sealing slide 3 located inside the treatment cylinder 1. The first sealing slide 2 and the second sealing slide 3 divide the treatment cylinder 1 into a first cavity, a second cavity, and a third cavity. The first sealing slide 2 and the second sealing slide 3 are each provided with a circular array of multiple first through holes 7, second through holes, and elastic components. A slider 8 is slidably arranged inside the first through hole 7. A hollow cylindrical filter ring 9 connected to the elastic component is provided on the top of the slider 8. A third through hole is opened on the slider 8 and communicates with the hollow cavity of the hollow cylindrical filter ring 9. The third through hole communicates with the first through hole 7. A connecting rod 10 is movably arranged inside the second through hole and fixedly connected to the inner wall of one side of the treatment cylinder 1. A cleaning rod 11 located inside the hollow cylindrical filter ring 9 is provided at the other end of the connecting rod 10.

[0026] The treatment cylinder 1 is closed at one end and open at the other end. A water inlet pipe is installed at the opening, and wastewater enters from the opening. The telescopic component is located at the closed end and will not be damaged.

[0027] Meanwhile, when the first sealing slide 2 and the second sealing slide 3 need to maintain sliding, they can also prevent wastewater leakage. Their structure can be referenced from that of a syringe, which is existing technology and will not be described in detail here.

[0028] The telescopic assembly includes an electric telescopic rod 12 mounted on the processing cylinder 1. The telescopic end of the electric telescopic rod 12 is connected to the first sealing slide 2 and the second sealing slide 3. The electric telescopic rod 12 drives the first sealing slide 2 and the second sealing slide 3 to move.

[0029] The first through hole 7 is matched with the slider 8. This arrangement allows the slider 8 to move inside the first through hole 7 when pressure is generated and the water pressure passes through the third through hole.

[0030] The diameter of the first through hole 7 is larger than the diameter of the third through hole, and the diameter of the third through hole is larger than the diameter of the hollow cylindrical filter ring 9. By setting the diameters to decrease sequentially, the water pressure generated is greater.

[0031] The top of the hollow cylindrical filter ring 9 is closed, which ensures that the pressure pushes the hollow cylindrical filter ring 9 out.

[0032] The elastic component includes a hollow cylinder 13 disposed on the top of the first sealing slide 2 and the second sealing slide 3. A spring 14 is disposed inside the hollow cylinder 13. A piston disc 15 is disposed on one side of the spring 14. A movable rod 16 is disposed on one side of the piston disc 15. The top of the movable rod 16 passes through the hollow cylinder 13 and is connected to the hollow cylindrical filter ring 9. When water pressure is generated, the water pressure drives the hollow cylindrical filter ring 9, causing the movable rod 16 to drive the piston disc 15 to stretch the spring 14, thereby causing displacement.

[0033] It should be noted that the selection of spring 14 can be based on Hooke's Law, which is existing technology and will not be elaborated on here.

[0034] The bottom of the processing cylinder 1 is provided with a discharge port 17, and a sealing plate 18 is provided on the discharge port 17. Impurities are discharged by removing the sealing plate 18.

[0035] A cleaning brush is provided on the outside of the cleaning rod 11. The cleaning brush is in contact with the filter surface of the hollow cylindrical filter ring 9. This arrangement improves the effect of impurity removal.

[0036] Two hollow cylindrical filter rings with different pore sizes enable multi-stage filtration.

[0037] The bottom of the treatment cylinder 1 is equipped with a drain pipe (not shown in the figure), through which wastewater is discharged.

[0038] The working principle of this invention is as follows: First, the wastewater from soybean peptone production is introduced into the treatment cylinder 1. The wastewater first enters the first chamber (at this time, the hollow cylindrical filter ring 9 is located inside the first through hole 7 and has not extended). The telescopic component is activated, which drives the first sealing slide 2 and the second sealing slide 3 to move and squeeze the wastewater inside the first chamber. The pressure generated acts on the first sealing slide 2, pushing the slider 8 to drive the hollow cylindrical filter ring 9 to extend from inside the first through hole 7. The hollow cylindrical filter ring 9 drives the elastic component to stretch, thereby allowing the wastewater to pass through the hollow cylindrical filter ring 9 and enter the second chamber. The wastewater entering the second chamber also generates a pressure difference. The pressure difference also acts on the second sealing slide plate 3, pushing the slider 8 to extend the hollow cylindrical filter ring 9 from the inside of the first through hole 7. The hollow cylindrical filter ring 9 drives the elastic component to stretch, so that the wastewater enters the third chamber through the filtration of another hollow cylindrical filter ring 9. Thus, impurities in the wastewater are removed through multi-stage filtration. Then, the telescopic component is pulled in the opposite direction, the pressure disappears, and the elastic component drives the hollow cylindrical filter ring 9 to make the slider 8 enter the inside of the first through hole 7. At this time, when entering, the hollow cylindrical filter ring 9 moves on the impurity removal rod 11, thereby removing impurities on the filter surface of the hollow cylindrical filter ring 9 and preventing clogging.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
