Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically to an oil-water separation treatment device with an automatic oil scraping function. Background Art

[0002] According to the different oil drainage methods, the oil-water separation methods of the oil separator can be divided into: manual oil drainage or suction oil drainage by suction truck, gravity oil drainage, mechanical oil drainage, and the above oil drainage methods can be combined and innovated at will, but there are some problems with the above oil drainage methods:

[0003] 1) Manual oil drainage or oil suction by sewage suction trucks requires regular manual cleaning or regular use of sewage suction trucks to drain oil. This method of oil drainage requires a lot of manpower. Due to the odor and dirtiness of the environment, few people are willing to do it and the efficiency is low.

[0004] 2) Gravity oil drainage, using the cone structure above the oil-water separation area to collect and concentrate the oil. When the oil layer reaches a certain height, it overflows in a directional manner and flows into the internal or external oil storage barrel. This oil-water separation method has low working efficiency, the oil layer cannot be completely discharged, and it will cause the oil layer to agglomerate. In addition, the dynamic changes of the liquid level are large, and the discharged oil contains a large amount of water.

[0005] 3) Mechanical oil discharge, using a chain belt structure or a rotating scraper mechanism to scrape the oil into an internal or external oil storage barrel. This oil-water separation method has high working efficiency, but the water content in the oil is high, and there are high requirements for the liquid level adjustment function, especially the change in water flow rate will affect the oil-water separation quality (high water content). The main reason is that it is not possible to control the dynamic balance between the water inlet, the scraper (5) height and gap, and the water outlet adjustment height.

[0006] 4) The above-mentioned oil drainage method is combined and innovative. From the perspective of various combined oil drainage methods currently in the market, there are two main problems: one is that the dynamic change of the liquid level affects the stability of the oil scraping function, and the other is that the water content in the oil is relatively high.

[0007] In summary, the oil-water separation technology currently used in oil separators on the market has the following four main problems:

[0008] 1) The dynamic balance between water inlet, oil level and water outlet adjustment height cannot be well controlled, thus affecting the operating efficiency of the oil scraper equipment;

[0009] 2) The separated oil quality is not ideal (high water content);

[0010] 3) The oil-water separation rate is not high (the water discharged at the end contains a lot of oil, and the oil remaining in the box (1) is easy to agglomerate and difficult to clean);

[0011] 4) Due to the structure, the oil scraping area is difficult to clean.

[0012] Therefore, the present invention aims to solve the technical problems that cannot be solved by the above-mentioned prior art. Summary of the invention

[0021] When the scraper moves toward the climbing panel and does not abut against the climbing panel, the self-locking device abuts against the mounting member;

[0022] When the scraper plate abuts against the climbing panel and moves toward the top of the climbing panel, the self-locking device abuts against the mounting member and generates relative sliding;

DETAILED DESCRIPTION

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0051] It should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0052] like Figure 1-Figure 14 As shown, the present invention provides an oil-water separation treatment device with automatic oil scraping function, comprising: a transmission component 2 and a translation component 3 arranged on a box body 1; the box body 1 is usually an open container, and the box body 1 is used to hold a liquid mixture, and the liquid mixture is a mixture of at least two liquids with different densities and immiscible with each other. In the specification of the present invention, a mixture of oil and water is used as an example of a liquid mixture, but it does not mean that the present invention is limited to oil-water separation. One end of the translation component 3 is connected to the transmission component 2, and the transmission component 2 is used to drive the translation component 3 to perform reciprocating translational motion in the box body 1. Therefore, the translation component 3 is movably connected to the box body 1, so that the translation component 3 can be translated on the box body 1.

[0053] When the box body 1 is an open container, the translation assembly 3 is placed on the top surface of the box body 1. Figure 1 As shown, the transmission assembly 2 can perform reciprocating translation motion on the top surface of the box body 1;

[0054] When the box body 1 is a non-open container, for example, the box body 1 has a top cover that can be opened and closed to prevent the spread of odor, and the translation component 3 can be arranged on the inner wall of the box body 1;

[0055] Regardless of whether the translation component 3 is arranged on the top or the inner wall of the box body 1, the transmission component 2 is arranged outside the box body 1, so as to avoid the liquid mixture in the box body 1 from affecting the transmission component 2, and the translation component 3 can perform reciprocating translation motion under the drive of the transmission component 2.

[0056] The inner wall of the box body 1 is provided with a climbing panel 4, one end of which is immersed below the liquid surface of the liquid mixture in the box body 1, and the other end of which extends to the outside of the box body 1. Figure 1 As shown, the bottom of the translation assembly 3 is also immersed below the liquid surface of the liquid mixture. The side wall of the box body 1 can be provided with a discharge port, and the climbing panel 4 extends to the outside of the box body 1 through the discharge port, so that the separated oil can be discharged from the box body 1 from the discharge port to achieve oil-water separation. The part of the climbing panel 4 extending outward from the discharge port can prevent the separated oil from remaining along the outer wall of the box body 1.

[0057] When performing oil-water separation, the translation assembly 3 first moves horizontally at a uniform speed from the rear end of the transmission assembly 2 (the end of the transmission assembly 2 away from the climbing panel 4) to the front end (the end of the transmission assembly 2 close to the climbing panel 4), such as Fig. 9 From point A to point C in the figure, the bottom of the translation component 3 abuts against the bottom of the climbing panel 4 at point C. During the movement of the translation component 3 from point C to the head end of the transmission component 2, the bottom of the translation component 3 abuts against the climbing panel 4 and slides along the climbing panel 4 to scrape the oil from the discharge port or directly from the top of the box body 1, thereby achieving the effect of oil-water separation. After the translation component 3 reaches the head end of the transmission component 2, it moves in the opposite direction to the tail end. During the movement from the head end to the tail end, the translation component 3 may or may not contact the liquid mixture, as shown in the following implementation. Regardless of whether the translation component 3 contacts the liquid mixture during the movement from the head end to the tail end, after it moves to the tail end of the transmission component 2, the translation component 3 will be reset to the initial position, that is, the bottom of the translation component 3 is immersed below the liquid surface of the liquid mixture.

[0058] Through the design of the above structure, the present invention is completely different from the traditional oil scraping equipment. The present invention is completely unaffected by water quality such as water inlet height, water inlet size, and whether there is foam.

[0059] Compared with the gravity oil drainage in the prior art, the present invention eliminates the complex cone top structure design of the gravity oil drainage, and the box body 1 of the present invention can adopt an open design, which is easy to process;

[0060] Compared with the mechanical oil discharge in the prior art, the present invention is superior to the mechanical roller oil scraping of the traditional rotary oil scraper, and has a larger oil scraping area;

[0061] Compared with the mechanical oil discharge in the prior art, the present invention is superior to the chain oil scraping of the traditional chain belt structure oil scraper, and the whole oil scraping process will not bring water into the oil collection barrel;

[0062] Compared with the various oil discharge combinations in the prior art, the present invention does not rely on the water outlet regulating device (that is, it is not affected by factors such as the water outlet height and the water outlet size), and eliminates the influence of the dynamic balance among the water inlet volume, the oil level and the water outlet regulating height on the oil scraping efficiency; the translation component 3 is detachable for easy cleaning; there are few fault points; the oil scraping efficiency is very high, and the separated oil is of high quality (very little water content); the oil-water separation rate is high (the water discharged at the end contains less oil); there is very little oil remaining in the casing 1 (the translation component 3 increases the fluidity of the oil layer, solving the problem of oil agglomeration and difficulty in cleaning in the casing 1); the mechanical structure is external (the transmission component 2 is arranged outside the casing 1) to prevent oil from solidifying on the mechanical structure, thereby ensuring stable operation of the equipment, easy operation and easy maintenance.

[0063] The outer wall of the box body 1 is provided with a mounting bracket for mounting the transmission assembly 2, and the transmission assembly 2 is arranged on the mounting bracket. The transmission assembly 2 is composed of an active member 22 connected to the driving device 21, a driven member 23, a first transmission member 24 sleeved outside the active member 22 and the driven member 23, and a second transmission member 25 arranged on the first transmission member 24. A dust box with a C-shaped cross-section is provided on the mounting bracket, and the opening of the dust box faces the box body 1. The driving device 21 is fixed to the mounting bracket through an adjustable support, and the support and the mounting bracket are connected by screws, and a slide groove is provided on the mounting bracket to facilitate the adjustment of the position of the support, thereby facilitating the adjustment of the position of the driving device 21. In this embodiment, we provide a specific structure The transmission component 2 is explained, wherein the active member 22 and the driven member 23 are both gears movably connected to the dustproof box, and a slide groove is provided on the dustproof box to adjust the relative position between the active member 22 and the driven member 23. At the same time, the active member 22 is connected to the driving device 21, and the driven member 23 can rotate under the drive of the first transmission member 24. Correspondingly, a chain is used as the first transmission member 24, which is sleeved on the two gears. By adjusting the relative positions of the two gears on the dustproof box, the tightness of the chain is adjusted, and the second transmission member 25 movably connected to one end of the translation component 3 is provided on the chain. The motor is used as the driving device 21 and is connected to the gear as the active member 22. The motor can drive the active member 22 to rotate, and the rotation of the active member 22 drives the chain to rotate, and then the second transmission member 25 thereon is driven to move through the chain, such as Figure 4 As shown, driven by the chain, the second transmission member 25 can move from point A to point B, and then change the direction of movement through the driven member 23, from point B to point C, and finally change the direction again at point D through the active member 22. In order to ensure that the translation assembly 3 connected to the second transmission member 25 performs reciprocating translational motion, the translation assembly 3 and the second transmission member 25 need to be movably connected, and it is necessary to ensure that the active connection point between the two is located on the line connecting the centers of the active member 22 and the driven member 23. For example, a bearing is provided on the second transmission member 25, and the translation assembly 3 is sleeved outside the bearing. In this way, the translation assembly 3 can be driven to perform reciprocating translational motion by the transmission assembly 2. It should be noted that the above embodiment is only one of many embodiments of the transmission assembly 2. For example, the active member 22 and the driven member 23 can be belt rollers, and the first transmission member 24 can be a belt; the active member 22 and the driven member 23 can be gear shafts, and the first transmission member 24 can be a belt with teeth, and many other embodiments. As long as the driving device 21 can drive the active member 22 to drive the first transmission member 24 to rotate, the first transmission member 24 can change direction at the driven member 23 .

[0064] Furthermore, the transmission assembly 2 further includes a slide bar 26 and a slider assembly 27. A dust cover can be provided at the opening of the dust box toward the box body 1. The slide bar 26 is provided on the dust cover and is located on one side close to the box body 1. Figure 4As shown, the slider assembly 27 is sleeved on the slide bar 26 and movably connected with the slide bar 26. The slider assembly 27 can move on the slide bar 26. The slider assembly 27 is movably connected with the second transmission member 25 through the lever 28. The dust cover is provided with a slide groove. The lever 28 passes through the slide groove and is connected with the second transmission member 25. The transmission assembly 2 is movably connected with the slider assembly 27. The slider assembly 27 and the translation assembly 3 can be fixedly connected or detachably connected. In order to facilitate equipment cleaning, a detachable connection is usually adopted to connect the translation assembly 3 and the slider assembly 27. In this embodiment, we provide a specific structure of a slider assembly 27 and a second transmission member 25 for illustration. The slider assembly 27 is a C-shaped structure, and sleeves are provided on its two opposite surfaces. The slider assembly 27 is sleeved on the slide rod 26 through the sleeves. A connecting hole connected to the lever 28 is provided on the other surface of the slider assembly 27. The lever 28 is connected to the slider assembly 27 through the connecting hole. The second transmission member 25 is composed of a first connecting section connected to the first transmission member 24, an extension section extending toward the slide rod 26, and a pushing section provided on the extension section. The first connecting section and the pushing section are respectively located at two ends of the extension section. The extension section is used to keep the pushing section away from the first transmission member 24 to prevent the lever 28 movably connected thereto from colliding with the active member 22 or the driven member 23. A U-shaped groove is provided on the pushing section, and the lever 28 is located in the U-shaped groove, and the opening of the U-shaped groove always points to the inside of the closed shape formed by the first transmission member 24, such as Figure 4 As shown, when the second transmission member 25 is located at point A, the U-shaped slot of the push section opens vertically downward, when the second transmission member 25 is located at point B, the opening of the U-shaped slot faces the center of the driven member 23, when located at point C, the opening of the U-shaped slot opens vertically upward, and when located at point D, the opening of the U-shaped slot faces the center of the active member 22. Thus, the second transmission member 25 can fix the motion trajectory of the lever 28 on the line between the center of the active member 22 and the center of the driven member 23 through the U-shaped slot, as shown in FIG. Figure 4 As shown, the lever 28 can only perform reciprocating translational motion between the active member 22 and the driven member 23, so that the slider assembly 27 can perform reciprocating translational motion on the slider 26, thereby causing the translation assembly 3 to perform reciprocating translational motion. It should be noted that in actual applications, as long as the second transmission member 25 can drive the slider assembly 27 to translate along the slider 26 through the lever 28, and the lever 28 described in the present invention can also be a bearing set on the second transmission member 25, as long as the lever 28 can achieve translational motion of the slider assembly 27 without driving the slider assembly 27 to rotate. A quick-release joint can also be used between the lever 28 and the slider assembly 27 as a connection method between the two.

[0065] The climbing panel 4 is tiltedly arranged in the box body 1, the highest point of the climbing panel 4 is located below the transmission assembly 2, and the highest point of the climbing panel 4 is provided with an extension plate extending to the outside of the box body 1, and a recovery device 8 is provided outside the box body 1, usually an oil collection barrel with an oil drain valve is used as the recovery device 8, and the recovery device 8 is located below the extension plate of the climbing panel 4, such as Figure 1 As shown, it is used to recover the oil separated from the box 1. The lowest point of the climbing panel 4 extends in the box 1 away from the highest point, as shown in FIG. Figure 5 As shown. The translation assembly 3 is composed of a mounting member 31 and a scraper 5 movably connected to the mounting member 31 through a third transmission member 32. A connecting member 33 is provided at one end of the mounting member 31, and the mounting member 31 is connected to the transmission assembly 2 through the connecting member 33. A displacement member 34 is provided at one end of the mounting member 31 away from the connecting member 33, and the mounting member 31 is movably connected to the box body 1 through the displacement member 34. Figure 6 As shown, the mounting member 31 is composed of a disassembly section provided with a connecting member 33, and a sliding section connected to the disassembly section through a second connecting section, the sliding section and the disassembly section are respectively arranged at both ends of the second connecting section, the displacement member 34 is arranged on the sliding section, and the displacement member 34 can be a roller axially connected to the sliding section, the scraper 5 is composed of a mounting section 51 connected to the mounting member 31 through a third transmission member 32, and an abutment section 52, the third transmission member 32 is arranged on both sides of the mounting section 51, the abutment section 52 is arranged below the mounting section 51, and the side walls of the abutment section 52 and the mounting section 51 are both provided with side wall scrapers 5 abutting against the inner wall of the box body 1, as shown in FIG. Figure 6 As shown. In this embodiment, we provide a specific translation assembly 3 structure for illustration. The connecting member 33 can be a card plate with a slot, which is engaged with the sliding sleeve of the slider assembly 27 through the card plate slot, so as to realize the detachable connection between the mounting member 31 and the slider assembly 27, which is convenient for maintenance and cleaning. When a fault occurs (or the external force exceeds the design value), this card plate connection method can ensure that the scraper 5 and the slider assembly 27 fall off quickly, which can protect both the motor and the scraper 5, and can continue to work after reinstallation. The third transmission member 32 can be two groups of connecting rods, one end of one group of connecting rods is connected to the inner wall shaft of the disassembly section, and the other end is connected to the mounting section 51 shaft of the scraper 5, and one end of the other group of connecting rods is connected to the inner wall shaft of the sliding section, and the other end is connected to the mounting section 51 shaft of the scraper 5, as shown in FIG. Figure 7 When the bottom of the abutting section 52 is not in contact with the climbing panel 4, the mounting section 51 is in a vertical state, and one side of the mounting section 51 abuts against the second connecting section, or a lever is provided on the mounting section 51, and the lever is placed on the top surface of the disassembly section and the top surface of the sliding section, as shown in FIG. Figure 7As shown, the contact section 52 extends toward the head end of the transmission assembly 2. When oil and water are separated, the oil will float above the water surface, which is called floating oil. The bottom of the contact section 52 and the lowest point of the climbing panel 4 should at least penetrate below the water surface. When oil and water are separated, the scraper 5 is located at the tail end of the transmission assembly 2. Driven by the transmission assembly 2, the scraper 5 moves from point A to point C, making horizontal linear motion, and scraping the floating oil toward the head end. When the scraper 5 reaches point C, the bottom of the contact section 52 abuts against the climbing panel 4, as shown in FIG. Figure 8 As the scraper 5 continues to move toward the head end, driven by the inclined climbing panel 4, the scraper 5 is also driven upward to bring the floating oil to the climbing panel 4, as shown in FIG. Fig. 9 As shown, as the scraper 5 continues to translate, under the action of the connecting rod and gravity, the scraper 5 is slowly lifted, and the oil is also brought to a higher position on the climbing panel 4, as shown in FIG. Fig.10 As shown, until the scraper 5 moves horizontally to the limit position, the floating oil is pushed into the recovery device 8, as shown in FIG. Fig.11 In the process of the bottom of the abutting section 52 and the top surface of the climbing panel 4 being abutted and then being lifted, the mounting plate rotates with the third transmission member 32 and the connection between the disassembly section and the sliding section as the axis. In order to prevent the scraper 5 from turning over during the lifting process and causing the scraped oil to be scattered back into the box body 1, each set of connecting rods is usually composed of two parallel connecting rods, such as Figure 3 , 7 It should be noted that, in addition to the connecting rod, the third transmission member 32 may also be any other commercially available product or prior art that can enable the scraper 5 to be lifted without turning over.

[0066] In the above embodiment, the scraper 5 can be driven upward by the climbing panel 4 after being translated to the climbing panel 4, so as to take out and separate the oil from the tank 1, but in the process of moving to the tail end and resetting, it will still move down along the climbing panel 4 and then move back to the tail end in the reverse direction. In this way, the scraper 5 will push the floating oil in the tank 1 in the reverse direction. In view of this, a symmetrical climbing panel 4 and a recovery device 8 can be set on the tank 1 for two-way recovery. As one of the embodiments of the present invention, two-way recovery should be listed within the protection scope of the present invention.

[0067] If the user's space or site area is insufficient, oil recovery can only be performed in one direction. The present invention also provides an implementation method of one-way oil scraping, wherein the scraper 5 is provided with an open groove and a self-locking device 6, one end of the self-locking device 6 is located on the side of the scraper 5 away from the mounting member 31, and is movably connected to the scraper 5 through a reset member, and the other end extends through the open groove to the other side of the scraper 5 and extends to the bottom of the mounting member 31, such as Figure 6 , 7 As shown;

[0068] When the scraper 5 moves toward the climbing panel 4 and does not abut against the climbing panel 4, the self-locking device 6 abuts against the mounting member 31, and the top surface of the self-locking device 6 abuts against the end surface of the second connecting section of the mounting member 31, and the abutting point is point P;

[0069] When the scraper 5 abuts against the climbing panel 4 and moves toward the top of the climbing panel 4, the self-locking device 6 abuts against the mounting member 31 and slides relative to it, while squeezing the reset member, such as Fig.12 As shown;

[0070] When the scraper 5 moves to the top surface of the climbing panel 4, the self-locking device 6 is separated from the mounting member 31. Under the action of the reset member, the self-locking device 6 pops up to the maximum position. When the scraper 5 reaches the top surface of the climbing panel 4 and moves in the opposite direction, the scraper 5 will move down along the climbing panel 4. During the downward movement, the scraper 5 will move downward with the connection between the third rotating member and the mounting member 31 as the center of the circle. During the movement, the end of the self-locking device 6 abuts against the mounting member 31. After abutting, the self-locking device 6 will jam the scraper 5. In the absence of external force, the scraper 5 cannot fall, so that the scraper 5 will not move down along the climbing panel 4 again. The return process is in a high-position movement, and this height is maintained to move horizontally to the tail end to ensure that the abutting section 52 of the scraper 5 will not touch the liquid surface, thereby preventing the scraper 5 from scraping the floating oil in the box 1 to the tail end during the reset process to the tail end, thereby causing an oil accumulation dead angle between the scraper 5 and the box 1. After reaching the tail end, the self-locking device 6 can be manually pressed down so that the end of the self-locking device 6 will no longer abut against the mounting member 31. Under the action of gravity, it can be reset, allowing the scraper 5 to be immersed in the oil-water mixture again and start a new scraping action. If it is troublesome to manually unlock and reset the self-locking device 6, an unlocking push rod 7 can be provided on the box body 1. The unlocking push rod 7 is located on the other side opposite to the climbing panel 4, so that it is at the tail end. The unlocking push rod 7 can be hinged with the box body 1 so that the unlocking push rod 7 can be freely flipped. Figure 3 , 5 As shown, the self-locking push rod can separate the end of the self-locking device 6 from the mounting member 31 before the scraper 5 moves to the tail end to change the running direction. In this embodiment, we provide a specific implementation of the self-locking device 6 and the unlocking push rod 7. The self-locking device 6 can be a tube with an inclined setting and a U-shaped cross section, one end of which is connected to the mounting section 51 axis, and a torsion spring is sleeved on the connecting shaft. One end of the torsion spring is connected to the mounting section 51, and the other end is connected to the self-locking device 6. The unlocking push rod 7 can be a tube with a U-shaped cross section hinged on the box body 1. The above is only one of the many implementations of the self-locking device 6 and the unlocking push rod 7. The present invention scrapes the oil by running the scraper 5 at a low position and returns at a high position, bringing the oil layer to the recovery device 8 again and again.
