Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a pipeline for color degradation of dyeing and printing wastewater. Background Technology

[0002] Dyeing and printing wastewater contains a large amount of color. While biochemical treatment degrades some of the color, certain shades, such as red, are ultimately difficult to remove, resulting in a slightly reddish appearance in the discharged wastewater. Current treatment methods typically involve adding ferrous sulfate during pretreatment or sodium hypochlorite during discharge, using iron salt adsorption or oxidation to degrade the color. Alternatively, an electrolysis process can be added to the wastewater treatment process, allowing color elements to float to the surface via flocculation at the electrodes, replacing the need for external chemical additives.

[0003] Regardless of the method used to treat the color degradation problem in dyeing and printing wastewater, a large amount of precipitated impurities will be generated in the wastewater. These precipitated impurities often do not settle completely during the treatment process, but a small amount of impurities will still settle during the subsequent drainage process.

[0004] These impurities settle at the bottom of the drain pipe. Although most of them are washed away by the water flow, a small amount of impurities will still settle and adhere to the bottom of the drain pipe. Over time, the amount of impurities adhering to the bottom of the drain pipe will increase, causing scaling, affecting drainage and even leading to blockages. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a pipeline for color degradation of dyeing and printing wastewater, so as to solve the technical problems in the prior art.

[0006] To achieve the above objectives, this utility model provides a pipeline for color degradation of dyeing and printing wastewater, including a water conveying pipe for transporting wastewater, wherein the water conveying pipe is a square pipe, characterized in that the pipeline for color degradation further includes:

[0007] A sludge collection tank is provided at the bottom of the water supply pipe, and a removable sludge drawer is provided inside the sludge collection tank. A sludge discharge port is provided at the connection between the bottom of the water supply pipe and the sludge collection tank.

[0008] A rotating baffle is installed at the sewage outlet. The width of the rotating baffle is greater than the width of the sewage outlet. The rotating baffle is rotatably connected to the water supply pipe via a rotating shaft. One end of the rotating shaft passes through the side wall of the water supply pipe and is rotatably connected to it.

[0009] Furthermore, multiple sludge collection tanks are provided and are arranged at equal intervals at the bottom of the water supply pipe, and several supports are also provided on the water supply pipe.

[0010] Furthermore, a sliding pin is provided at the port of the rotating shaft extending out of the water pipe. The sliding pin passes through the rotating shaft from the vertical plane and is slidably connected to it, and the sliding pin can be removed.

[0011] Furthermore, the water supply pipe is also equipped with a vertical baffle, which is fixedly connected to the outer wall of the water supply pipe and can block the sliding nail to prevent the rotating shaft from rotating. At this time, the rotating baffle is in a vertical standing state.

[0012] Furthermore, the water supply pipe is also equipped with a horizontal baffle, which is fixedly connected to the outer wall of the water supply pipe and can block the sliding pin to prevent the rotating shaft from rotating. At this time, the rotating baffle is in a horizontal lying state.

[0013] Furthermore, a recess is provided on the other side of the drain outlet relative to the rotating partition. The width of the drain outlet plus the width of the recess is greater than the width of the rotating partition, and a sealing gasket is provided inside the recess.

[0014] Furthermore, the upper end of the drain drawer has an opening, and the size of the opening is larger than the size of the drain outlet. A sealing gasket is provided between the outer side plate of the drain drawer and the sludge collection trough.

[0015] Furthermore, a scraper is fixedly connected inside the drain drawer, with the upper end of the scraper located above the drain opening, and the scraper is made of a flexible material that can be bent.

[0016] The beneficial effects of this utility model are as follows: 1. The water supply pipe is made into a square pipe, which facilitates cleaning. A sludge collection tank is set at the bottom of the water supply pipe to collect sediment and prevent sediment from adhering to the bottom of the drainage pipe and causing scale buildup, which would affect drainage.

[0017] 2. A drain outlet is installed above the sludge collection tank, and a rotating baffle is installed at the drain outlet. When the rotating baffle is upright, it can prevent impurities from settling and avoid them being washed away by the water flow, keeping the impurities in the sludge collection tank. When the rotating baffle is lowered horizontally, it can seal the drain outlet, allowing the sludge collection tank to be opened without worrying about sewage flowing away.

[0018] 3. The vertical and horizontal movement of the rotating partition is controlled by a sliding pin in conjunction with a vertical baffle and a horizontal baffle. The vertical baffle and the horizontal baffle block the sliding pin, forcing the rotating shaft to stop rotating, thus keeping the rotating partition in either a vertical or horizontal position. The structure is simple and the operation is convenient.

[0019] 4. A drain drawer is installed inside the sludge collection tank for easy removal and disposal after sufficient sediment has been collected. The drain drawer is equipped with a scraper made of a flexible, bendable material, which scrapes off sediment adhering to the rotating partition when the drain drawer is pulled out.

These sedimented impurities will settle at the bottom of the drainage pipe. Although most of them will be washed away by the water flow, a small amount of impurities will still settle and adhere to the bottom of the drainage pipe. Over time, the amount of sediment attached to the bottom of the drainage pipe will increase, causing scaling, affecting drainage and even causing blockage. Therefore, this utility model designs a water conveyance pipe 101 for transporting sewage. The water conveyance pipe 101 is a square pipe.

[0031] A sludge collection trough 103 is installed at the bottom of the water supply pipe 101. The sludge collection trough 103 contains a removable drain drawer 110, and a drain outlet 104 is provided at the connection point between the bottom of the water supply pipe 101 and the sludge collection trough 103.

[0032] The drain drawer 110 has an opening at its top, which is larger than the drain outlet 104. A sealing gasket is provided between the outer side panel of the drain drawer 110 and the sludge collection tank 103. A scraper 111 is also fixedly connected inside the drain drawer 110. The upper end of the scraper 111 is located above the drain outlet 104, and the scraper 111 is made of a flexible material that can be bent.

[0033] Preferably, there are multiple sludge collection tanks 103, which are arranged at equal intervals at the bottom of the water supply pipe 101, and the water supply pipe 101 is also provided with several supports 102.

[0036] A drain outlet 104 is provided above the sludge collection tank 103, and a rotating baffle 105 is provided at the drain outlet 104. When the rotating baffle 105 is upright, it can block the sedimentation of impurities, preventing the sediment from being washed to the rear by the water flow, and keeping the sediment in the sludge collection tank 103.

[0037] A sliding pin 107 is provided at the end of the rotating shaft 106 extending outside the water supply pipe 101. The sliding pin 107 passes through the rotating shaft 106 vertically and is slidably connected to it, and the sliding pin 107 can be removed. A vertical baffle 108 is also provided on the water supply pipe 101. The vertical baffle 108 is fixedly connected to the outer wall of the water supply pipe 101 and can block the sliding pin 107 to prevent the rotating shaft 106 from rotating.
