Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, specifically a purification device for metal cleaning wastewater. Background Technology

[0002] The wastewater collected from the production line is temporarily stored in the metal cleaning water collection tank. According to the level gauge in the tank, the booster pump automatically pressurizes the wastewater and sends it to the subsequent pretreatment tank. In the pretreatment tank, chemical reagents are used to adjust the water, and particulate impurities and suspended solids (SS) are allowed to precipitate. After that, the water is pumped into the tank for subsequent metal removal treatment.

[0003] When pumping water from the pretreatment tank, the inlet is usually fixed above the sediment at the bottom of the tank. This means that during the pumping operation, the water flow can easily carry some sediment into the subsequent pipelines. Therefore, there is an urgent need for a purification device for metal cleaning wastewater to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a purification device for metal cleaning wastewater, so as to solve the problem mentioned in the background art that when the pretreatment tank is pumped out, the inlet is generally fixed above the sediment at the bottom of the tank, which makes it easy for the water flow to carry some sediment into the subsequent pipeline during the pumping operation.

[0005] This utility model provides the following technical solution: a purification device for metal cleaning wastewater, including a sedimentation mechanism, wherein the sedimentation mechanism includes a tank body and a water extraction pipe connected to a pump body, which is embedded in the tank body to extract the water. It also includes a positioning mechanism, which includes a float frame that floats on the surface of the liquid in the pool. In addition, a connecting frame is attached to the upper surface of the float frame and embedded with the water inlet sleeve, and the water inlet sleeve is located in the recessed area of ​​the connecting frame, so that the opening of the water inlet sleeve is always below the liquid surface. The inlet sleeve is connected to the inlet end of the pumping pipe via a flexible hose.

[0006] To achieve the above technical solution, a floating frame moves with the liquid level, and the recessed area of ​​the connecting frame ensures that the inlet sleeve is always below the liquid level. This allows the device to always pump water from the uppermost clear liquid. Compared with existing technologies, this device significantly reduces the sediment content in the pumped water, improves the protection of the pump body, and facilitates subsequent purification processes.

[0007] As a further improvement to this utility model, the bottom of the pool body is funnel-shaped and extends horizontally to form a sewage pipe.

[0008] The above technical solution facilitates the removal of sediment from the tank.

[0009] As a further improvement to this utility model, a number of guide rods are connected to the pool body along the direction of movement of the floating frame, and the floating frame moves on the guide rods.

[0010] The above technical solution improves the guidance of the floating frame movement.

[0011] As a further improvement to this utility model, the connecting frame is also connected to a baffle plate that blocks the water inlet of the water inlet sleeve, and the water inlet sleeve is provided with a blocking mechanism inside.

[0012] To achieve the above technical solution, a shield is formed above the water inlet sleeve.

[0013] As a further improvement to this utility model, the hose is coiled or corrugated.

[0014] The above technical solution allows the hose to deform as the inlet sleeve descends or rises.

[0015] As a further improvement to this utility model, the blocking mechanism includes a blocking ring connected to the inner wall of the water inlet sleeve. The blocking ring is connected to a T-shaped member by a spring at the water inlet of the water inlet sleeve, and the rod of the T-shaped member extends through the through hole of the blocking ring and connects to the sealing plate.

[0016] The above technical solution avoids the untreated raw liquid from directly entering the water inlet sleeve.

[0017] As a further improvement to this utility model, the top of the T-shaped member is frustoconical.

[0018] The above technical solution improves the guiding effect of the T-shaped component tip on the liquid.

[0019] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a floating frame that moves with the liquid level, and the recessed area of ​​the connecting frame ensures that the water inlet sleeve is always below the liquid level, so that the device can always pump water from the uppermost clear liquid.

[0020] 2. Compared with the prior art, this device significantly reduces the content of sediment in the extracted water, improves the protection effect on the pump body, and facilitates subsequent purification processes. Attached Figure Description

[0027] Example 1: Refer to the attached diagram in the instruction manual. Figure 1-3 This utility model provides a purification device for metal cleaning wastewater, including a sedimentation mechanism 100. The sedimentation mechanism 100 includes a tank body 110 and a water extraction pipe 111 connected to a pump body, which is embedded in the tank body 110 to extract the water. It also includes a positioning mechanism 200, which includes a float frame 210 that floats on the liquid surface of the pool body 110; In addition, a connecting frame 211 is connected to the upper surface of the float frame 210 and embedded in the water inlet sleeve 212, and the water inlet sleeve 212 is located in the recessed area of ​​the connecting frame 211, so that the opening of the water inlet sleeve 212 is always below the liquid surface. The inlet sleeve 212 is connected to the inlet end of the pumping pipe 111 via a flexible hose 213.

[0028] The bottom of the pool body 110 is funnel-shaped and extends horizontally to form a sewage pipe 112. Several guide rods 215 are connected to the pool body 110 along the movement direction of the float frame 210, and the float frame 210 moves on the guide rods 215. The hose 213 is coiled or corrugated.

[0029] During use, the original solution is mixed with chemical agents in pool 110 and gradually precipitates; After sedimentation, the pump body starts pumping water. At this time, the water flows through the inlet sleeve 212, the hose 213, and the pumping pipe 111 until it reaches the pump body. Meanwhile, during the pumping process, the float frame 210 gradually descends with the liquid level, so that the inlet sleeve 212 is always below the liquid level.

[0030] Example 2: Refer to the attached diagram in the instruction manual. Figure 4 The difference between this embodiment and the above embodiment is that: a baffle plate 214 is also connected to the connecting frame 211 to block the water inlet of the water inlet sleeve 212, and a blocking mechanism 300 is provided inside the water inlet sleeve 212. The blocking mechanism 300 includes a blocking ring 310 connected to the inner wall of the water inlet sleeve 212. A T-shaped member 311 is connected to the blocking ring 310 facing the water inlet of the water inlet sleeve 212 by a spring, and the rod of the T-shaped member 311 extends through the through hole of the blocking ring 310 and connects to the sealing plate 312. The top of the T-shaped member 311 is truncated cone-shaped.

[0031] In use, the blocking effect of the baffle plate 214 on the top of the water inlet sleeve 212 makes it difficult for chemical agents to directly enter the water inlet sleeve 212, while the blocking effect of the baffle ring 310 closely attached to the sealing plate 312 can prevent unprecipitated raw liquid from directly entering the water inlet sleeve 212 and the hose 213.
