Description

Technical Field

[0001] This utility model relates to the field of air flotation devices, and in particular to a high-efficiency air flotation device for industrial wastewater treatment. Background Technology

[0002] Industrial wastewater treatment flotation devices are water treatment equipment that utilizes flotation separation technology to attach suspended solids, grease, colloids, and other impurities in wastewater to tiny air bubbles, forming a flotation body with a density less than water, thereby achieving solid-liquid separation or liquid-liquid separation.

[0003] In existing technologies, common air flotation devices, in order to further separate impurities, also use air flotation components to add flocculants to the water. However, common air flotation components rely on only a set of fixed tubular feeders to discharge microbubbles and flocculants. Since the feeders themselves cannot move, the discharge position is also fixed. Thus, during use, the flocculants can only move freely to the water area far away from the dischargers, resulting in low overall device treatment efficiency. Therefore, a high-efficiency industrial wastewater treatment air flotation device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency industrial wastewater treatment flotation device, which aims to solve the problem in the prior art that "the flocculant can only move to the water area far away from the discharge device by free diffusion, resulting in low overall treatment efficiency of the device".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency industrial wastewater treatment flotation device, comprising a tank, a scraping component being provided on the inner wall of the tank near the top, a flotation component being provided on the front surface of the tank, and a transmission component being provided on the rear surface of the tank;

[0006] The air flotation component includes a feeder that penetrates and is rotatably connected to the inner wall of the housing.

[0008] The transmission assembly also includes a transmission disc, which is rotatably connected to the rear surface of the housing, and the transmission disc is connected to the rotating shaft via a belt drive.

[0009] As a further description of the above technical solution:

[0010] A transmission block is fixedly connected to the rear surface of the transmission disk, a slide rail is sleeved on the outer wall of the transmission block, and a protrusion is provided on the inner wall of the drive disk.

[0011] As a further description of the above technical solution:

[0012] The outer wall of the protrusion is fitted with a second slide rail, which is fixedly connected to the first slide rail by a transmission rod. The transmission rod is slidably connected to the rear surface of the housing.

[0013] As a further description of the above technical solution:

[0014] The inner wall of the protrusion is threaded with a locking bolt, the rear surface of the locking bolt is fixedly connected with a protruding plate, the outer wall of the locking bolt is fitted with a washer, and the front end of the locking bolt is fixedly connected with a knob.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting a rotatable feeder, the feeder can rotate inside the box when the whole device is working normally. When the feeder rotates, the orientation of its top opening will also change, so that microbubbles and flocculants can be sprayed into the box. This can promote the rapid mixing of flocculants in the water in various parts of the box, shorten the time required for impurity flocculation, and improve the overall processing efficiency of the device.

[0031] 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.

[0032] Reference Figures 1-3An embodiment of this utility model is provided: a high-efficiency industrial wastewater treatment flotation device, including a tank 1 for storing wastewater, a scraping component 3 for cleaning impurities after flocculation is provided on the inner wall of the tank 1 near the top, a flotation component 2 for conveying microbubbles and flocculant into the tank 1 is provided on the front surface of the tank 1, and a transmission component 4 for transmitting motion is provided on the rear surface of the tank 1.

[0033] Reference Figures 2-4 The air flotation component 2 includes a feeder 23 for dispensing flocculant and microbubbles. The feeder 23 is rotatably connected to the inner wall of the housing 1. The top of the feeder 23 has an opening, through which water mixed with flocculant and microbubbles can be sprayed out. Therefore, the spray range can be expanded by adjusting the orientation of the feeder 23. The scraping component 3 includes a drive motor 31, which is mounted on the front surface of the housing 1. The rear end of the output shaft of the drive motor 31 is fixedly connected to a rotating shaft 32. The rotating shaft 32 can be rotated by starting the drive motor 31. The rotating shaft 32 is rotatably connected to the inner wall of the housing 1. The transmission component 4 includes a drive disc 46 for rotating the feeder 23. The drive disc 46 is fixedly connected to the rear surface of the feeder 23. When the drive disc 46 rotates, the feeder 23 will be driven to rotate synchronously.

[0034] Reference Figures 3-5The transmission assembly 4 also includes a transmission disc 41 for transmitting power. The transmission disc 41 is rotatably connected to the rear surface of the housing 1. The transmission disc 41 is connected to the rotating shaft 32 via a belt drive. When the rotating shaft 32 rotates, it drives the transmission disc 41 to rotate via the belt. A transmission block 42 for moving the slide rail 43 is fixedly connected to the rear surface of the transmission disc 41. The slide rail 43 is sleeved on the outer wall of the transmission block 42. When the transmission disc 41 rotates, it can drive the transmission block 42 to move on the inner wall of the slide rail 43. At the same time, the slide rail 43 is driven to move left and right. The inner wall of the drive disc 46 is provided with a protrusion 47 for driving the drive disc 46 to swing. A slide rail 45 for pressing the protrusion 47 is sleeved on the outer wall of the protrusion 47. The slide rail 45 and the slide rail 43 are fixedly connected via a transmission rod 44. The transmission rod 44 is slidably connected to the rear surface of the housing 1. When the slide rail 43 moves left and right, it will drive the transmission block 42 to move on the inner wall of the slide rail 43. The transmission rod 44 drives the slide rail 45 to move synchronously. When the slide rail 45 moves left and right, it will squeeze the protrusion 47 and drive the drive disk 46 to swing. The distance between the protrusion 47 and the rotation center of the drive disk 46 is greater than the distance between the rotation center of the transmission disk 41 and the transmission block 42. Therefore, there will be no dead angle when the slide rail 45 drives the protrusion 47 to move. The inner wall of the protrusion 47 is threaded with a locking bolt 471. The rear surface of the locking bolt 471 is fixedly connected with a protruding plate 473 for pulling the washer 474. The outer wall of the locking bolt 471 is fitted with a washer 474. By rotating the locking bolt 471, the protruding plate 473 can be driven to squeeze the washer 474. In this way, the washer 474 can be driven to squeeze the drive disk 46, thereby fixing the protrusion 47. The front end of the locking bolt 471 is fixedly connected with a knob 472. By adjusting the distance between the center position of the protrusion 47 and the center position of the drive disk 46, the swing amplitude of the drive disk 46 can be adjusted.

[0035] Reference Figures 2-4The air flotation assembly 2 also includes a centrifugal pump 21 for powering the feeding. The centrifugal pump 21 is installed on the outer wall of the housing 1. The outer wall of the centrifugal pump 21 has two sets of feed ports. One set of feed ports is connected to a water extraction pipe 24 for extracting water. The water extraction pipe 24 passes through and is fixedly connected to the inner wall of the housing 1. The water extraction pipe 24 can extract the treated water inside the housing 1 for mixing with flocculant. The other set of feed ports is connected to a mixing pipe. The mixing pipe can introduce flocculant into the centrifugal pump 21. The flocculant and water flow can be mixed under the drive of the centrifugal pump 21 and discharged along the output end of the centrifugal pump 21. The output end of the centrifugal pump 21 is connected to a feeder. The connector 22 of 23 is connected to the centrifugal pump 21. The external pipe of the connector 22 is equipped with a pressure relief valve, which can make micro bubbles appear in the water flow inside the pipe. The connector 22 is installed on the front surface of the housing 1. The feeder 23 is rotatably connected to the rear end of the connector 22. The connector 22 will guide the water mixed with flocculant into the interior of the feeder 23. The scraping assembly 3 also includes a transmission chain 33 for driving the scraper 34 to move. The transmission chain 33 is installed on the outer wall of the rotating shaft 32. The scraper 34 is installed on the outer wall of the transmission chain 33. When the rotating shaft 32 rotates, it will drive the transmission chain 33 to rotate, thus scraping off the impurities floating on the top of the water.

[0036] Working principle: Centrifugal pump 21 draws treated water from tank 1 through pumping pipe 24. Flocculant is added through mixing pipe at another inlet. After mixing in centrifugal pump 21, the mixture enters feeder 23 through connector 22. Pressure relief valve outside connector 22 generates microbubbles in the water flow. Drive motor 31 drives shaft 32 to rotate. Shaft 32 drives transmission disc 41 to rotate via belt. Transmission block 42 on transmission disc 41 moves within slide rail 1 43, driving slide rail 2 45 to the left and right via transmission rod 44. Moving to the right, the slide rail 45 presses against the protrusion 47 on the inner wall of the drive disc 46, causing the drive disc 46 to drive the feeder 23 to swing. At the same time, the drive disc 46 itself rotates, causing the feeder 23 to both rotate and swing inside the housing 1. Its top opening sprays water mixed with microbubbles and flocculants in all directions, promoting the rapid mixing of flocculants in the water inside the housing 1. Impurities adhere to the microbubbles, forming air flotation bodies that float to the water surface. The rotation of the rotating shaft 32 also drives the transmission chain 33 and the scraper 34 to rotate, scraping off the scum on the water surface and achieving solid-liquid separation.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
