Description

Technical Field

[0001] This utility model relates to the field of wastewater pretreatment technology, specifically a water supply and drainage wastewater pretreatment device. Background Technology

[0002] Wastewater pretreatment refers to the process of removing larger solids, suspended solids, grease, some toxic substances, or other pollutants from wastewater using physical, chemical, or biological methods before it enters the main treatment unit (such as biological or chemical treatment). This aims to improve the efficiency of subsequent treatment units and reduce treatment costs.

[0003] The existing patent with publication number CN220159375U proposes a municipal water supply and drainage sewage pretreatment device. The device is equipped with a stirring mechanism. By starting the motor, the motor drives the transmission rod to rotate, which in turn drives the transmission rod to drive three stirring blades to stir the sewage at the bottom of the treatment tank. By setting a stirring rod, the sewage in the middle of the treatment tank can be stirred, so that the sewage and the chemical solution can be fully mixed, thereby improving the treatment efficiency.

[0004] However, when the device stirs the wastewater after adding the chemicals, the stirring effect of a single stirring rod is poor, making it difficult to quickly mix the wastewater and chemicals, resulting in low mixing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a pretreatment device for water supply and drainage sewage, so as to solve the problem that the existing device has poor mixing effect of a single stirring rod, cannot quickly mix sewage and chemicals, and has low efficiency during mixing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pretreatment device for water supply and drainage sewage, comprising a base, a treatment box fixedly mounted on the upper end of the base, an interception box fixedly mounted on the upper end of the treatment box, a reagent inlet pipe fixedly mounted on one side of the upper end of the treatment box, and an accelerating fusion structure fixedly mounted on the lower end of the treatment box. The accelerating fusion structure includes a fixed frame fixedly mounted on the lower end of the treatment box, a motor fixedly mounted on the bottom end of the fixed frame, a first rotating shaft fixedly mounted on the output end of the motor, a drive gear fixedly mounted on the outer wall of the first rotating shaft located at the lower end of the treatment box, and a second rotating shaft rotatably mounted on both sides of the upper end of the fixed frame. A driven gear is fixedly mounted on the outer wall of the second rotating shaft. The upper ends of the second rotating shaft and the first rotating shaft both extend into the interior of the treatment box and are respectively fixedly connected to a second stirring rod and a first stirring rod. Sealing rings are fixedly mounted on the inner walls of the treatment box located on the outer walls of the first rotating shaft and the second rotating shaft.

[0007] Preferably, the inner wall of the interception box is provided with a guide structure, the guide structure includes a placement plate fixedly installed on the inner wall of the interception box, guide rods fixedly installed on both sides of the inner wall of the interception box, an interception frame provided at the upper end of the placement plate, and guide grooves provided on both sides of the interception frame.

[0008] Preferably, the inner wall of the interception frame is fixedly provided with two sets of lifting plates.

[0009] Preferably, a drain pipe is fixedly installed at the lower end of one side of the treatment box, and a control valve is fixedly installed on the outer wall of the drain pipe.

[0010] Preferably, the outer wall of the interception frame is in contact with the interior of the interception box.

[0011] Preferably, vertical rods are fixedly installed on both sides of the processing box, and horizontal plates are fixedly installed on both sides of the interception box. A reserved slot is opened inside the horizontal plate, and the vertical rod is located inside the reserved slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) By setting up an accelerated fusion structure, the rotation of the active gear and the driven gear can make the liquid flow in different directions during the rotation process, thereby accelerating the mixing treatment between the agent and the sewage and speeding up the mixing efficiency.

[0014] 2) By setting up a guide structure, when the interception frame is installed inside the interception box, the guide rod, guide groove and placement plate can speed up the fixing of the interception frame inside the interception box, and facilitate the removal of the intercepted impurities later.

The accelerating fusion structure 5 includes a fixing frame 6 fixedly mounted on the lower end of the treatment tank 2, a motor 7 fixedly mounted on the bottom end of the fixing frame 6, a first rotating shaft 9 fixedly mounted on the output end of the motor 7, a driving gear 8 fixedly mounted on the outer wall of the first rotating shaft 9 located at the lower end of the treatment tank 2, and a second rotating shaft 12 rotatably mounted on both sides of the upper end of the fixing frame 6. A driven gear 13 is fixedly mounted on the outer wall of the second rotating shaft 12. The upper ends of the second rotating shaft 12 and the first rotating shaft 9 both lead to the interior of the treatment tank 2 and are respectively fixedly connected to a second stirring rod 14 and a first stirring rod 11. Sealing rings 10 are fixedly mounted on the inner walls of the treatment tank 2 located on the outer walls of the first rotating shaft 9 and the second rotating shaft 12.

[0023] See Figure 2 , Figure 4 Furthermore, it is found that two sets of lifting plates are fixedly installed on the inner wall of the interception frame 16, a sewage pipe is fixedly installed on the lower side of one side of the treatment box 2, a control valve is fixedly installed on the outer wall of the sewage pipe, the outer wall of the interception frame 16 is in contact with the interior of the interception box 3, vertical rods 20 are fixedly installed on both sides of the treatment box 2, and horizontal plates 21 are fixedly installed on both sides of the interception box 3. A reserved groove 22 is opened inside the horizontal plate 21, and the vertical rods 20 are located inside the reserved groove 22.

[0024] Specifically, the lifting plate facilitates the later lifting and removal of the interception frame 16, and after the vertical rod 20 enters the reserved slot 22, it can realize the quick docking and installation of the interception box 3 and the processing box 2.

[0025] Example 2

[0026] See Figure 4 Furthermore, based on Embodiment 1, the inner wall of the interception box 3 is provided with a guide structure 15. The guide structure 15 includes a placement plate 17 fixedly installed on the inner wall of the interception box 3, guide rods 19 fixedly installed on both sides of the inner wall of the interception box 3, an interception frame 16 installed at the upper end of the placement plate 17, and guide grooves 18 opened on both sides of the interception frame 16.

[0028] In actual operation, the sewage to be treated is added into the interception box 16. After being filtered, the sewage enters the treatment tank 2. Mixed agents are added into the treatment tank 2 through the agent inlet pipe 4. The motor 7 is started, which causes the drive gear 8 to drive the driven gear 13 to rotate. This causes the first stirring rod 11 and the second stirring rod 14 to mix and stir the sewage and agents, thus accelerating the treatment of sewage.
