Description

Technical Field

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

[0002] Dyeing and printing wastewater refers to the wastewater discharged from dyeing and printing plants, wool dyeing and finishing plants, and silk factories that process cotton, linen, chemical fibers and their blended products, as well as silk. The volume and quality of dyeing and printing wastewater vary depending on the type of fiber and processing technology. Dyeing and printing plants typically produce large volumes of wastewater, consuming 100-200 tons of water per ton of textiles processed, with 80%-90% of this being discharged as wastewater. Dyeing and printing wastewater is characterized by its large volume, high content of organic pollutants, high alkalinity, and significant variations in water quality, making it one of the most difficult types of industrial wastewater to treat. The wastewater contains dyes, sizing agents, auxiliaries, oils, acids and alkalis, fiber impurities, sand, and inorganic salts.

[0003] In the wastewater treatment process, waste residue needs to be settled and separated from water. However, the waste settled at the bottom of the water needs to be cleaned up. Currently, most of the operations require manual retrieval from the bottom of the pool, which is not only inefficient but also wastes manpower. If the settled waste is not treated in time, it may mix with the water again over a long period of time, and the recycling of wastewater will not achieve good results. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater treatment and reuse device for dyeing and printing, which can accelerate the collection of waste and improve the efficiency of decontamination; it eliminates the need for manual retrieval of waste from the bottom of the water, saving the cost of manual retrieval, and improving the effect of purifying wastewater and increasing the recycling rate.

[0005] To achieve the above objectives, a wastewater treatment and reuse device for dyeing and printing is provided, comprising: a housing, a first scraper disposed at the lower left corner of the bottom of the housing, a first filter screen disposed in the middle of the first scraper, second scrapers inserted into the outer ends of both ends of the first scraper, second filter screens disposed in the middle of the second scrapers, a pull strap fixedly connected to the middle bend of the first scraper, a rotating rod fixedly connected to the other end of the pull strap, a first gear fixedly connected to the top of the rotating rod, a second gear meshing with the rear side of the first gear, and a motor fixedly connected to the middle of the bottom end of the second gear; and an empty [device] fixedly connected to the front right side of the bottom of the housing. The hollow cylinder has a through hole at the bottom of its circumference.

A suction tube is fixedly connected to the rear side wall of the centrifugal pump, and the other end of the suction tube is inserted into the rear side of the hollow cylinder. A sludge discharge pipe is fixedly connected to the top of the centrifugal pump. A sludge storage box is set at the top center of the right side wall of the housing. A third filter screen is set at the bottom of the sludge storage box. The other end of the sludge discharge pipe passes through the inside of the sludge storage box. Inserting one end of the sludge discharge pipe into the sludge storage box facilitates waste collection and cleaning by staff.

[0006] According to the aforementioned dyeing and printing wastewater treatment and reuse device, the bottom of the rear side wall and the right side wall of the box are provided with sliding grooves, and the other end of the second scraper is inserted into the sliding groove. The sliding groove is provided to maintain the stable movement of the first scraper and the second scraper.

[0007] According to the aforementioned dyeing and printing wastewater treatment and reuse device, a stirring rod is provided in the middle of the hollow cylinder. The two ends of the stirring rod are rotatably connected to the top and bottom ends of the hollow cylinder, respectively. A second motor is fixedly connected to the bottom end of the stirring rod. The second motor is fixedly connected inside the bottom end of the support rod, and the second motor is concealed inside the support rod to save space.

[0008] According to the aforementioned dyeing and printing wastewater treatment and reuse device, a rotating rod is inserted into the outer circumferential surface of the support rod, and a groove is provided in the middle of the outer wall of the top of the hollow cylinder. The groove is inserted into the bottom end of the rotating rod to maintain the stability of the rotating rod during operation.

[0009] According to the aforementioned dyeing and printing wastewater treatment and reuse device, a connecting rod is rotatably connected to the top center of the second gear. The top of the connecting rod is fixedly connected to the bottom of the top plate. A fixing rod is fixedly connected to the bottom of the motor. The other end of the fixing rod is fixedly connected to the top plate to prevent the motor from being suspended in the air and to maintain its stable operation.

[0010] According to the aforementioned dyeing and printing wastewater treatment and reuse device, an outlet is provided at the bottom of the front side wall of the tank, and a fourth filter screen is installed inside the outlet screen to filter the wastewater more thoroughly.

[0011] According to the dyeing and printing wastewater treatment and reuse device, the first scraper is L-shaped, and the number of through holes is multiple.

[0012] Beneficial effects:

[0013] 1. This utility model is equipped with a first scraper, a second scraper, a first filter screen, a second filter screen, and a pull belt. The first filter screen and the second filter screen are installed inside the first scraper and the second scraper respectively. The first scraper is inserted into the second scraper. The pull belt pulls the first scraper, so that the first scraper and the second scraper scrape towards the upper right corner of the box, gathering the settled printing and dyeing waste close to the hollow cylinder, which speeds up the waste collection and improves the decontamination efficiency.

[0014] 2. This utility model, by setting up a hollow cylinder, a suction pipe, a centrifugal pump, a waste discharge pipe, and a waste storage box, gathers printing and dyeing waste around the hollow cylinder, uses the centrifugal pump to pump it into the hollow cylinder, then uses the suction pipe to pump it in, and finally uses the waste discharge pipe to discharge it into the waste storage box for collection.
