Description

Technical Field

[0001] This utility model relates to the field of air flotation machines, and in particular to an air flotation scum treatment device. Background Technology

[0002] An air flotation machine is a machine that uses small or microbubbles to float impurities in a medium to the surface of the water. This air flotation device can be used for some fine impurities in water with a specific gravity close to that of water, which are difficult to sink or float due to their own weight.

[0003] In water treatment, dissolved air flotation (DAF) machines need to discharge treated clean water. The working principle of an DAF machine is to generate microbubbles, causing suspended solids, grease, and other impurities in the water to adhere to the bubbles and float to the surface, forming scum. This scum is then removed by a scraper or similar equipment, while the purified water is discharged from the bottom or side of the DAF machine. However, current DAF machines are not very efficient at collecting scum, resulting in low scum treatment efficiency, which affects the water purification efficiency. Furthermore, the filter screen at the drain outlet is easily clogged by scum and other impurities, affecting drainage.

[0004] In response to this technical problem, this application proposes a flotation machine scum treatment device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flotation scum treatment device. This device aims to improve the collection and treatment of scum, thereby increasing the efficiency of subsequent scum treatment and water purification, and preventing the filter screen at the drainage outlet from being blocked by scum and other impurities, thus affecting drainage.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A flotation machine scum treatment device, comprising:

[0008] The air flotation machine body for treating wastewater has a scum pushing component installed on the top side of the interior of the air flotation machine body for pushing scum, and an outlet is opened at the middle of the left side of the bottom side of the interior of the air flotation machine body. A filter screen is fixedly connected inside the outlet, and an anti-clogging component is installed on the bottom side of the interior of the air flotation machine body to prevent the filter screen from clogging.

[0009] A filter plate for collecting scum has a lifting rod rotatably connected to the middle of its bottom side. A cylinder is installed inside the bottom of the air flotation machine body, and the driving end of the cylinder is fixedly connected to the bottom end of the lifting rod. An tilting assembly for tilting the filter plate is provided inside the rear of the air flotation machine body. A guide plate is fixedly connected to the rear top of the air flotation machine body. A scum collection box for collecting scum is provided at the rear of the air flotation machine body.

[0010] Furthermore, the slag pushing assembly includes a bidirectional screw and a limiting rod disposed on the inner top side of the air flotation machine body. The bidirectional screw is rotatably connected to the left end of the inner top side of the air flotation machine body, and the limiting rod is fixedly connected to the right end of the inner top side of the air flotation machine body.

[0011] Furthermore, the bidirectional screw and the limiting rod are connected by two scrapers, one end of which is threaded to the outer wall of the bidirectional screw, and the other end of which is slidably connected to the outer wall of the limiting rod.

[0012] Furthermore, the anti-blocking component includes a reciprocating lead screw and a round rod disposed at the left end of the inner bottom side of the air flotation machine body. The reciprocating lead screw is rotatably connected to the left end of the inner bottom side of the air flotation machine body, and the round rod is fixedly connected to the left end of the inner bottom side of the air flotation machine body.

[0013] Furthermore, the reciprocating lead screw is located on the left side of the round rod, and the reciprocating lead screw and the round rod are connected by a brush plate. One end of the brush plate is threaded to the outer wall of the reciprocating lead screw, and the other end of the brush plate is slidably connected to the outer wall of the round rod.

[0014] Furthermore, both the bidirectional screw and the reciprocating lead screw have pulleys fixedly connected to their front ends, and the two pulleys are connected by a belt.

[0015] Furthermore, the tilting assembly includes two baffles fixedly connected to the rear side of the inner wall of the air flotation machine body, two limiting plates fixedly connected to the bottom side of the baffles, two impact rods fixedly connected to the rear side of the bottom side of the filter plate, a limiting shaft fixedly connected to the rear end of the impact rods, the limiting shaft being disposed between the two limiting plates, and a gravity block fixedly connected to the front side of the bottom side of the filter plate.

[0016] Furthermore, a water outlet pipe is fixedly connected to the left side of the air flotation machine body, a control valve is installed on the top side of the water outlet pipe, and a motor is installed on the front left side of the air flotation machine body, with the drive end of the motor fixedly connected to the front end of the bidirectional screw.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the scraper can drive the brush plate to work while the belt and pulley are working, so that the scum collection work and the filter plate anti-clogging work can be carried out at the same time. This allows the device to perform two tasks at the same time, thereby improving work efficiency and saving resources to a certain extent. When drainage is required, the control valve can be opened to allow water to be discharged through the outlet pipe.

[0019] 2. In this utility model, the combination of the impact rod and the baffle allows the filter plate to discharge the scum, thereby quickly collecting the scum and improving the efficiency of scum collection and treatment. Furthermore, the combination of the limiting shaft and the limiting plate allows the filter plate to be reset and will not tilt, thus not affecting the next scum collection.

[0027] 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 protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 2 and Figure 5 One embodiment of this utility model provides: a flotation machine scum treatment device, comprising:

[0029] The air flotation unit 1, used for wastewater treatment, has an outlet located at the middle of the left side of the bottom interior of the air flotation unit 1. A filter screen 22 is fixedly connected inside the outlet. A bidirectional screw 12 is rotatably connected to the left side of the top interior of the air flotation unit 1. A limit rod 13 is fixedly connected to the right side of the top interior of the air flotation unit 1. The bidirectional screw 12 and the limit rod 13 are connected by two scrapers 11. One end of the scraper 11 is threaded onto the outer wall of the bidirectional screw 12, and the other end is slidably connected to the outer wall of the limit rod 13. A reciprocating screw 14 is rotatably connected to the left side of the bottom interior of the air flotation unit 1. A reciprocating screw 14 is fixedly connected to the left side of the bottom interior of the air flotation unit 1. A round rod 15 is connected to the left side of the reciprocating screw 14. The reciprocating screw 14 and the round rod 15 are connected by a brush plate 16. One end of the brush plate 16 is threaded to the outer wall of the reciprocating screw 14, and the other end of the brush plate 16 is slidably connected to the outer wall of the round rod 15. The front ends of the bidirectional screw 12 and the reciprocating screw 14 are both fixedly connected to pulleys 21. The two pulleys 21 are connected to each other by a belt. The left side of the air flotation machine body 1 is fixedly connected to a water outlet pipe 4. A control valve 5 is installed on the top side of the water outlet pipe 4. A motor 3 is installed on the front left side of the air flotation machine body 1. The drive end of the motor 3 is fixedly connected to the front end of the bidirectional screw 12.

[0030] Specifically, when wastewater is treated in the flotation unit 1, scum will float to the top of the wastewater. The motor 3 drives the bidirectional screw 12 to rotate, causing the two scrapers 11 to move in the same direction, so that the scum gathers together. When the bidirectional screw 12 rotates, the pulley 21 and belt drive the reciprocating screw 14 to rotate, so that the brush plate 16 moves back and forth on the bottom side of the flotation unit 1. The brush plate 16 cleans the filter screen 22, preventing the scum from clogging the filter screen 22 and affecting drainage. The belt and pulley 21 enable the scrapers 11 to drive the brush plate 16 to work while they are working, so that the scum gathering and filter plate 22 anti-clogging work can be carried out at the same time. This allows the device to perform two tasks at the same time, thereby improving work efficiency and saving resources to a certain extent. When drainage is required, the control valve 5 can be opened to allow water to be discharged through the outlet pipe 4.

[0031] Reference Figures 2-4A filter plate 2 for collecting scum is provided. A lifting rod 9 is rotatably connected to the middle of the bottom side of the filter plate 2. A cylinder 8 is installed on the bottom side of the air flotation machine body 1. The driving end of the cylinder 8 is fixedly connected to the bottom end of the lifting rod 9. A guide plate 6 is fixedly connected to the rear side of the top side of the air flotation machine body 1. A scum collection box 7 for collecting scum is provided on the rear side of the air flotation machine body 1. Two baffles 10 are fixedly connected to the rear side of the inner wall of the air flotation machine body 1. Two limiting plates 20 are fixedly connected to the bottom side of the baffles 10. Two impact rods 18 are fixedly connected to the rear side of the bottom side of the filter plate 2. A limiting shaft 19 is fixedly connected to the rear end of the impact rods 18. The limiting shaft 19 is located between the two limiting plates 20. A gravity block 17 is fixedly connected to the front side of the bottom side of the filter plate 2.

[0032] Specifically, when the two scrapers 11 gather the scum together, the scum will be scraped by the two scrapers 11 to the top of the filter plate 2. When the scum has accumulated to a certain amount, the cylinder 8 is activated, causing the cylinder 8 to push the lifting rod 9 upward. The lifting rod 9 then pushes the filter plate 2 upward slowly. During the upward movement of the filter plate 2, the impact rod 18 will slowly tilt under the action of the baffle 10, causing the filter plate 2 to tilt along with the impact rod 18. This causes the scum on the filter plate 2 to be poured out. The scum will then enter the scum collection box 7 through the guide plate 6, thus completing the collection of the scum and allowing it to proceed to the next step of processing. After the scum has been poured out, the cylinder 8 is activated, causing the lifting rod 9 to move downward and drive the filter plate 2 back into the filter plate. In the air flotation machine body 1, as the filter plate 2 descends, the impact rod 18 will slowly reset, causing the filter plate 2 to gradually become horizontal. After resetting, since the limiting shaft 19 can only move between the two limiting plates 20, the impact rod 18 cannot rotate backward, thus preventing the filter plate 2 from tilting forward. Furthermore, the presence of the gravity block 17 prevents the filter plate 2 from tilting backward. Through the cooperation of the impact rod 18 and the baffle 10, the filter plate 2 can discharge the scum, thereby quickly collecting the scum and improving the efficiency of scum collection and treatment. Moreover, with the cooperation of the limiting shaft 19 and the limiting plate 20, the filter plate 2 can reset without tilting, thus not affecting the next scum collection.

[0033] Working Principle: When wastewater is treated in the flotation unit 1, scum will float to the top of the wastewater. The motor 3 drives the bidirectional screw 12 to rotate, causing the two scrapers 11 to move in the same direction, making the scum gather together. When the bidirectional screw 12 rotates, the pulley 21 and belt drive the reciprocating screw 14 to rotate, causing the brush plate 16 to move back and forth on the bottom side of the flotation unit 1. The brush plate 16 cleans the filter screen 22, preventing the scum from clogging the filter screen 22 and affecting drainage. When drainage is required, the control valve 5 can be opened to allow water to be discharged through the outlet pipe 4. When the two scrapers 11 gather the scum together, the scum will be scraped by the two scrapers 11 to the top of the filter plate 2. When the scum has accumulated to a certain amount, the cylinder 8 is activated, causing the cylinder 8 to push the lifting rod 9 upward, thus pushing the lifting rod 9 upward. The filter plate 2 moves slowly upward. During this upward movement, the impact rod 18 tilts slowly under the action of the baffle 10, causing the filter plate 2 to tilt along with the impact rod 18. This causes the scum on the filter plate 2 to be poured out and enters the scum collection box 7 through the guide plate 6, thus completing the collection of scum for further processing. After the scum is poured out, the cylinder 8 is activated to cause the lifting rod 9 to move downward and drive the filter plate 2 back into the air flotation machine body 1. During the descent of the filter plate 2, the impact rod 18 slowly resets, causing the filter plate 2 to gradually become horizontal. After resetting, since the limiting shaft 19 can only move between the two limiting plates 20, the impact rod 18 cannot rotate backward, thus preventing the filter plate 2 from tilting forward. Furthermore, the presence of the gravity block 17 prevents the filter plate 2 from tilting backward.
