Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for treating pharmaceutical intermediate chemical wastewater. Background Technology

[0002] Aeration is a commonly used biochemical treatment method in the treatment of pharmaceutical intermediate chemical wastewater. By introducing air into the wastewater, it promotes the growth and metabolism of aerobic microorganisms, thereby converting organic matter in the wastewater into harmless substances. However, when there is excessive organic matter in the aeration tank, the microorganisms produce a large amount of gas during the decomposition of this organic matter. This gas, as it rises, combines with suspended solids in the liquid, forming a large amount of foam. If this foam is not removed, it will directly affect the subsequent treatment effect of the chemical wastewater. Utility Model Content

[0003] The main purpose of this invention is to provide a pharmaceutical intermediate chemical wastewater treatment device to solve the problem that the failure to remove foam from wastewater in existing technologies directly affects the subsequent treatment effect of chemical wastewater.

[0004] To achieve the above objectives, this utility model provides a pharmaceutical intermediate chemical wastewater treatment device, including an aeration tank, a support frame, a rotating shaft, a chain, a fixing rod, and a diversion plate;

[0005] There are two brackets, which are fixedly installed on both sides of the aeration tank. Two bearing seats are fixedly installed on the top of each bracket.

[0006] There are two rotating shafts, which are rotatably mounted on two bearing seats. Each rotating shaft is fitted with two sprockets. Each rotating shaft is connected to a drive component to drive its rotation.

[0007] There are two chains, each chain is mounted on two sprockets located on the same bracket;

The multiple fixed rods are arranged at intervals along the chain conveying direction, and each fixed rod is fixedly fitted with a scraper, which can be conveyed at the open of the aeration tank.

[0009] The two side walls of the diversion plate are fixedly installed on the opposite side walls of the aeration tank;

[0010] The diversion plate includes a horizontal section, a V-shaped section, and an inclined section, which are fixedly connected in sequence. A rotating rod is rotatably installed at the opening of the V-shaped section, and the rotating rod is rotatably installed on two opposite side walls of the aeration tank.

[0011] The rotating rod has multiple flexible fan blades arranged around its circumference and connected to a drive component for driving its rotation.

[0012] A collection pool is installed at the downstream end of the inclined section.

[0013] Preferably, the driving component is a motor, the output shaft of the motor is coaxially connected to any rotating shaft, and the base is fixedly connected to the bracket.

[0014] Preferably, the drive unit includes two pulleys and a belt;

[0015] One end of the rotating rod passes through the aeration tank and is fixedly connected to a leather wheel;

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example:

[0039] like Figure 1 , Figure 2As shown, this embodiment provides a pharmaceutical intermediate chemical wastewater treatment device, including an aeration tank 1, a support 10, a rotating shaft 20, a chain 30, a fixing rod 40, and a diversion plate 50. There are two supports 10, fixedly installed on both sides of the aeration tank 1, with two bearing seats 11 fixedly installed on the top of each support 10. There are two rotating shafts 20, rotatably mounted on the two bearing seats 11, with two sprockets 21 fixedly fitted on each shaft 20. Each shaft 20 is connected to a driving component 22 for driving its rotation. The driving component 22 is a motor, with its output shaft coaxially connected to either shaft 20, and its base fixedly connected to the support 10. There are two chains 30, each fitted onto two sprockets 21 located on the same support 10. Multiple fixed rods 40 are provided, each with both ends fixedly mounted on the sidewalls of two chains 30. These fixed rods 40 are spaced apart along the conveying direction of the chains 30, and each fixed rod 40 is fitted with a scraper 41, which can convey material at the opening of the aeration tank 1. The scraper 41 is made of rubber. The two sidewalls of the diversion plate 50 are fixedly mounted on opposite sidewalls of the aeration tank 1. The diversion plate 50 includes a horizontal section 51, a V-shaped section 52, and an inclined section 53, which are sequentially fixedly connected. A rotating rod 54 is rotatably mounted at the opening of the V-shaped section 52, rotatably mounted on the two opposite sidewalls of the aeration tank 1. Multiple flexible fan blades 55 are arranged circumferentially on the rotating rod 54, and the rotating rod 54 is connected to a drive component for its rotation. A collection tank 51 is located at the downstream end of the inclined section 53.

[0040] A large amount of foam is generated in aeration tank 1. This foam is suspended above the sewage. The drive component 22 starts to work. The drive component 22 drives the sprocket 21 to rotate through the rotating shaft 20. The sprocket 21 drives the chain 30 to start conveying. In the conveying state, the two chains 30 drive multiple fixed rods 40 to convey. The scraper 41 located below the chain 30 pushes the foam in the sewage. The pushed foam is transported to the horizontal section 51 and further into the V-shaped section 52. The drive component starts to work. The drive component drives multiple flexible fan blades 55 to rotate through the rotating rod 54. In the rotating state, the flexible fan blades 55 carry the foam to the inclined section 53. The foam on the inclined section 53 flows into the collection tank 51. With this structural setting, foam in chemical sewage can be separated quickly and effectively.

[0041] In addition, after the foam in the chemical wastewater is separated, it is pumped into the next wastewater treatment process.

[0042] The drive unit includes two pulleys 56 and a belt 57. One end of the rotating rod 54 extends out of the aeration tank 1 and is fixedly connected to one of the pulleys 56. The other pulley 56 is fixedly mounted on either of the rotating shafts 20, and the belt 57 is mounted on both pulleys 56. When the rotating shaft 20 rotates, it drives the rotating rod 54 to rotate through the pulleys 56 and the belt 57, thus avoiding the need for other separate power sources to drive the rotating rod 54.

[0043] The pharmaceutical intermediate chemical wastewater treatment device also includes a sedimentation tank 60 and an outlet pipe 61. The sedimentation tank 60 is located upstream of the aeration tank 1. The two ends of the outlet pipe 61 are located in the aeration tank 1 and the sedimentation tank 60, respectively, and a wastewater pump 62 is installed along the pipe. The wastewater first undergoes sedimentation in the sedimentation tank 60. After sedimentation, the wastewater is pumped to the aeration tank 1 by the wastewater pump 62 for aeration treatment.

[0044] A wastewater inlet pipe 70 is installed above the sedimentation tank 60. An aeration device 80 is installed at the bottom of the aeration tank 1. This invention uses the existing aeration device 80, so it will not be described in detail.
