An oily wastewater treatment device

Abstract

This utility model belongs to the field of oily wastewater treatment technology, specifically an oily wastewater treatment device. It consists of a filter screen, a fixed plate, a movable plate, and a scraper. Wastewater is poured into the inside of the filter screen through a connecting pipe on the lower side. The fixed plate, movable plate, and the protruding part inside the treatment tank work together to separate the filter screen into two parts. The wastewater passes through one part for filtration and is then discharged through the connecting pipe on the other side. When the filtered part becomes clogged, the movable plate retracts into the fixed plate. This prevents the filtered impurities from being scraped off by the movable plate when the filter screen rotates. The rotation of the filter screen moves unfiltered impurities to the filtration area, while the clogged impurities move to the upper part of the scraper. The movable plate returns to its original position, the filter screen continues to separate impurities, and the scraper rises to scrape off and push the impurities to the exposed environment. The scraper can then be cleaned. This method achieves rapid replacement and cleaning of the filter structure after clogging, improving the stability of the filtration process.

Description

Technical Field

[0001] This utility model relates to the field of oily wastewater treatment technology, specifically an oily wastewater treatment device. Background Technology

[0002] Oily wastewater, which is common in daily life, is a type of wastewater that is abundant, widespread, and seriously harmful. In order to prevent it from polluting the environment after discharge, it is necessary to use oily wastewater treatment equipment to purify it.

[0003] Existing oily wastewater treatment devices filter oily wastewater using filters. During the filtration process, solid particles in the wastewater adhere to the surface of the filter screen, forming a filter layer. Over time, this filter layer gradually thickens, increasing the resistance to wastewater passing through the filter screen and hindering filtration. Therefore, this paper proposes an oily wastewater treatment device to address the aforementioned problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An oily wastewater treatment device of this utility model includes a treatment tank, with a connecting pipe inside the treatment tank. A motor is fixedly connected to the outside of the treatment tank, and a gear is fixedly connected to the output end of the motor. A gear ring meshes with the outside of the gear, and the gear ring is rotatably connected to the treatment tank. A filter screen is fixedly connected to the outside of the gear ring. A fixing plate is fixedly connected to the inside of the treatment tank, and a cylinder is fixedly connected to the outside of the fixing plate. A movable plate is fixedly connected to the output end of the cylinder. Both the fixing plate and the movable plate are used in conjunction with the filter screen. A hydraulic cylinder is fixedly connected to the outside of the treatment tank, and a scraper is fixedly connected to the output end of the hydraulic cylinder. A baffle is fixedly connected to the outside of the scraper. This step involves setting a filter screen and fixing... The filter consists of a fixed plate, a movable plate, and a scraper. Wastewater is poured into the inside of the filter screen through a connecting pipe on the lower side. The fixed plate, movable plate, and the protruding part inside the treatment box work together to separate the filter screen into two parts. Wastewater passes through one part for filtration and then is discharged through the connecting pipe on the other side. When the filter part becomes clogged, the movable plate retracts into the fixed plate. This prevents the filtered impurities from being scraped off by the movable plate when the filter screen rotates. The rotation of the filter screen moves the unfiltered part to the filtration area, while the clogged part moves to the upper part of the scraper. The movable plate returns to its original position, the filter screen continues to separate, and the scraper rises to scrape off the impurities and push them to the exposed external environment. The scraper can then be cleaned. This allows for rapid replacement and cleaning of the filter structure after clogging, improving the stability of the filtration system.

[0006] Preferably, a concave plate is fixedly connected to the inner side of the processing box, and a convex plate is fixedly connected to the outer side of the baffle frame. The convex plate and the concave plate are used in conjunction. This step, by setting the concave plate and the convex plate, ensures that when the scraper moves the impurities upward, it will simultaneously move the baffle frame and the convex plate upward. The convex part of the convex plate enters and exits the concave part inside the concave plate, thereby vibrating the concave plate. This causes the concave plate to vibrate the filter screen, which in turn facilitates further separation of the filter screen from the impurities it intercepts, thus improving the stability of the cleaning process.

[0007] Preferably, an inclined plate is fixedly connected to the inside of the treatment box, and the inclined plate is used in conjunction with the filter screen. This step, by setting the inclined plate, guides the wastewater when it enters and exits the filter screen, so that it can quickly pass through the filter screen and be discharged through the connecting pipe on one side, thereby improving the filtration efficiency of the device.

[0008] Preferably, a rotating plate is rotatably connected to the outside of the treatment box, a lifting screw is threadedly connected to the inside of the rotating plate, and a connecting plate is rotatably connected to the outside of the lifting screw. This step, by setting the rotating plate, lifting screw, and connecting plate, allows the connecting plate at different positions to be adjusted to a suitable height during device installation by rotating the lifting screw. The connecting plate is then connected to the installation location with bolts, facilitating the setting of the tilt angle of the treatment box. This allows for adjustment of the device angle, enabling wastewater entering the treatment box to pass through the filter screen and connecting pipe more quickly under the influence of gravity and be discharged, further improving the filtration efficiency of the device.

[0009] Preferably, a limiting plate is fixedly connected to the outer side of the lifting screw, and the limiting plate and the rotating plate are used in conjunction. This step, by setting the limiting plate, ensures that when the lifting screw rotates to its maximum position, the limiting plate is pressed against the rotating plate, thereby making it difficult for the lifting screw to separate from the rotating plate and improving the stability of the device.

[0010] Preferably, a support plate is fixedly connected to the outer side of the connecting plate, and a reinforcing screw is threadedly connected to the inner side of the support plate. This step, by setting the support plate and the reinforcing screw, allows the connecting plate to be connected to the installation point by bolts. By rotating the reinforcing screw, one end of the reinforcing screw can be moved to be close to the ground, thereby providing further support to the connecting plate and further improving the stability of the device placement.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a filter screen, a fixed plate, a movable plate, and a scraper, allows wastewater to be poured into the inside of the filter screen through a connecting pipe on the lower side. The fixed plate, the movable plate, and the protruding part inside the treatment box work together to divide the filter screen into two parts, allowing the wastewater to pass through one part for filtration and then be discharged through the connecting pipe on the other side. When the filtered part becomes clogged, the movable plate retracts into the inside of the fixed plate, making it difficult for the filtered impurities to be scraped off by the movable plate when the filter screen rotates. The rotation of the filter screen causes the unfiltered part to move to the filtration area, while the part that has become clogged by filtration moves to the upper part of the scraper. The movable plate returns to its original position, the filter screen continues to divide, and the scraper rises to scrape off the impurities and push them to the exposed external environment. The scraper can then be cleaned. This achieves rapid replacement and cleaning of the filter structure after it becomes clogged, improving the stability of the filtration device.

[0013] 2. By setting up a concave plate and a convex plate, when the scraper moves the impurities upward, it will simultaneously move the baffle and the convex plate upward. The convex part of the convex plate enters and exits the concave part inside the concave plate, thereby vibrating the concave plate. This causes the concave plate to vibrate the filter screen, which in turn facilitates further separation of the filter screen from the impurities it intercepts, thus improving the stability of the cleaning process.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1 to 5 As shown, an oily wastewater treatment device includes a treatment tank 1, with a connecting pipe 2 connected to the inner side of the treatment tank 1. A motor 3 is fixedly connected to the outer side of the treatment tank 1, and a gear 4 is fixedly connected to the output end of the motor 3. A gear ring 5 meshes with the outer side of the gear 4, and the gear ring 5 is rotatably connected to the treatment tank 1. A filter screen 6 is fixedly connected to the outer side of the gear ring 5. A fixed plate 7 is fixedly connected to the inner side of the treatment tank 1, and a cylinder 8 is fixedly connected to the outer side of the fixed plate 7. A movable plate 9 is fixedly connected to the output end of the cylinder 8. Both the fixed plate 7 and the movable plate 9 are used in conjunction with the filter screen 6. A hydraulic cylinder 10 is fixedly connected to the outer side of the treatment tank 1, and a scraper 11 is fixedly connected to the output end of the hydraulic cylinder 10. A baffle frame 12 is fixedly connected to the outer side of the scraper 11. This step involves setting up the filter screen 6, the fixed plate 7, the movable plate 9, and the scraper. Wastewater is poured into the filter screen 6 through the lower connecting pipe 2 via plate 11. The filter screen 6 is divided into two parts by the cooperation of the fixed plate 7, the movable plate 9, and the protruding part inside the treatment box 1. The wastewater passes through one part for filtration and is then discharged through the other connecting pipe 2. When the filter part becomes clogged, the movable plate 9 retracts into the fixed plate 7, making it difficult for the impurities filtered by the filter screen 6 to be scraped off by the movable plate 9 when the filter screen 6 rotates. The rotation of the filter screen 6 causes the unfiltered part to move to the filtration area, while the part that has become clogged by filtration moves to the upper side of the scraper 11. The movable plate 9 returns to its original position, the filter screen 6 continues to divide, and the scraper 11 rises to scrape off the impurities and push them to the exposed external environment. The scraper 11 can then be cleaned. This allows for rapid replacement and cleaning of the filter structure after it becomes clogged, improving the stability of the filtration process.

[0024] Furthermore, such as Figure 1 and Figure 3As shown, a concave plate 13 is fixedly connected to the inner side of the processing box 1, and a convex plate 14 is fixedly connected to the outer side of the baffle frame 12. The convex plate 14 and the concave plate 13 are used in conjunction. This step, by setting the concave plate 13 and the convex plate 14, ensures that when the scraper 11 moves the impurities upward, it will simultaneously move the baffle frame 12 and the convex plate 14 upward. The convex part of the convex plate 14 enters and exits the concave part inside the concave plate 13, thereby vibrating the concave plate 13. This causes the concave plate 13 to vibrate the filter screen 6, which facilitates further separation of the filter screen 6 from the impurities it intercepts, thus improving the stability of the cleaning process.

[0025] Furthermore, such as Figure 1 and Figure 3 As shown, an inclined plate 15 is fixedly connected to the inner side of the treatment box 1. The inclined plate 15 and the filter screen 6 are used together. This step, by setting the inclined plate 15, guides the wastewater when it enters and exits the filter screen 6, so that it can quickly pass through the filter screen 6 and be discharged through the connecting pipe 2 on one side, thereby improving the filtration efficiency of the device.

[0026] Furthermore, such as Figure 1 As shown, a rotating plate 16 is rotatably connected to the outside of the treatment tank 1, and a lifting screw 17 is threadedly connected to the inside of the rotating plate 16. A connecting plate 18 is rotatably connected to the outside of the lifting screw 17. This step, by setting up the rotating plate 16, the lifting screw 17, and the connecting plate 18, allows the connecting plate 18 at different positions to be adjusted to a suitable height by rotating the lifting screw 17 during device installation. The connecting plate 18 is then connected to the installation location by bolts, which facilitates the tilting angle setting of the treatment tank 1. This allows for adjustment of the device angle, enabling wastewater entering the treatment tank 1 to pass through the filter screen 6 and the connecting pipe 2 more quickly under the influence of gravity and discharge, further improving the filtration efficiency of the device.

[0027] Furthermore, such as Figure 1 As shown, a limiting plate 19 is fixedly connected to the outer side of the lifting screw 17, and the limiting plate 19 and the rotating plate 16 are used together. By setting the limiting plate 19, when the lifting screw 17 rotates to the maximum position, the limiting plate 19 is pressed against the rotating plate 16, thereby making it difficult for the lifting screw 17 to separate from the rotating plate 16, thus improving the stability of the device.

[0028] Furthermore, such as Figure 1 As shown, a support plate 20 is fixedly connected to the outer side of the connecting plate 18, and a reinforcing screw 21 is threadedly connected to the inner side of the support plate 20. This step, by setting the support plate 20 and the reinforcing screw 21, allows the connecting plate 18 to be connected to the installation location by bolts. By rotating the reinforcing screw 21, one end of the reinforcing screw 21 can be moved to be close to the ground, thereby providing further support for the connecting plate 18 and further improving the stability of the device placement.

[0029] Working principle: Wastewater is poured into the inside of filter screen 6 through the lower connecting pipe 2. The filter screen 6 is divided into two parts by the cooperation of the fixed plate 7, the movable plate 9, and the protruding part inside the treatment box 1. The wastewater passes through one part for filtration by the guide of the inclined plate 15 and is discharged through the other connecting pipe 2. When the filtered part is blocked, the cylinder 8 drives the movable plate 9 to move, so that the movable plate 9 is retracted into the inside of the fixed plate 7. When the filter screen 6 rotates, the impurities filtered by it are not easily stuck to the movable plate 9 and are scraped off by the movable plate 9. Then the motor 3 is started, which drives the gear 4 to rotate, which drives the gear ring 5 to rotate, which drives the filter screen 6 to rotate. The unfiltered part moves to the filtration area, and the part blocked by filtration moves to the upper side of the scraper 11. The movable plate 9 is then moved back to its original position, so that the filter screen 6 continues to separate. The hydraulic cylinder 10 drives the scraper 11 to rise, which scrapes off the impurities and pushes them to the exposed external environment. The scraper 11 is then cleaned.
