Description

Technical Field

[0001] The utility model belongs to the technical field related to textile wastewater treatment, in particular to a three-stage filtering device for continuous spun colored yarns. Background Art

[0002] Continuous spinning colored silk wastewater refers to wastewater containing dyes and other chemicals generated during the continuous spinning process. This wastewater usually contains high concentrations of organic matter, salts, dyes, heavy metal ions and other pollutants, which have serious impacts on the environment and ecosystem. In addition, it contains a large amount of short silk fibers. During the recycling process, the pollutants need to be removed by chemical methods and then filtered by filtering equipment. However, it still has the following disadvantages in actual use:

[0003] In the process of filtering the wastewater from continuous spinning, it is first necessary to perform preliminary filtration through a coarse filtration device. During the preliminary filtration, after the wastewater is directly transported to the filter through a transfer container, the impurities in the wastewater will partially settle in the transfer container under the action of gravity, and the container needs to be opened regularly for cleaning, which is troublesome to use;

[0004] When filtering the wastewater from continuous spinning, the wastewater is filtered through multiple filters connected in series. After filtering, it is transported to the equipment for recycling. However, very small fiber debris may remain in the wastewater, or when the filtering structure is damaged, it can only be observed and determined in the water-using equipment, and the fault needs to be eliminated step by step. The wastewater filtration situation cannot be determined intuitively. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] Furthermore, an electric control valve 1 is fixed to the upper part of the peripheral side of the vertical material pipe, and the two bypass pipes are arranged parallel to each other. The vertical material pipe controls the on-off of the conveying through the electric control valve 1.

[0009] Furthermore, a cleaning waste liquid port is fixedly connected to the middle of the peripheral side of the backwash filter, and the cleaning waste liquid port is arranged horizontally. The backwash filter discharges the cleaning waste liquid therein through the cleaning waste liquid port.

[0010] Furthermore, a cleaning liquid inlet is fixedly connected to the rear of the peripheral side of the backwash filter at an angle, and an electric control valve 2 is fixed to the peripheral side of the curved pipe and the straight pipe at one end close to the backwash filter. The backwash filter inputs cleaning water through the cleaning liquid inlet, and the curved pipe and the straight pipe are controlled to be on and off by the electric control valve 2.

[0011] Furthermore, the upper portion of the transfer pipe is in an inverted U-shape, and a pressure sensor is fixed through the middle of the U-shaped circumference of the transfer pipe.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0025] See also Figure 1-4The utility model is a three-stage filtering device for continuous spinning, comprising a feed barrel 1, a backwash filter 2, a secondary filter 3 and a tertiary filter 4. The bottom end of the feed barrel 1 is fixedly connected with a vertical feed pipe 101, and the top end of the feed barrel 1 is fixedly connected with a device for inputting liquid to be filtered. When the feed barrel 1 is working, the liquid to be filtered is contained therein and transported to a bypass pipe 103 through the vertical feed pipe 101. The lower part of the circumference of the vertical feed pipe 101 is fixedly connected with two bypass pipes 103. When working, when the liquid to be filtered is transported to the bypass pipe 103, it is transported to the backwash filter 2 through the bypass pipe 103 for preliminary filtration. The two bypass pipes 103 are connected to the bypass pipe 103. The ends of the through pipes 103 away from the vertical material pipe 101 are fixedly connected to the backwash filter 2. The two backwash filters 2 work in turn during operation to perform preliminary filtration on the liquid to be filtered. The output end of the backwash filter 2 located at the top is fixedly connected to the elbow 203, and the output end of the backwash filter 2 located at the bottom is fixedly connected to the straight pipe 204. The end of the elbow 203 away from the backwash filter 2 is fixed to the middle of the circumference of the straight pipe 204 and is connected to the straight pipe 204. When working, the liquid output from the backwash filter 2 located at the top is transported to the straight pipe 204 through the elbow 203, and the filtered liquid output from the backwash filter 2 located at the bottom is directly transported to the backwash filter 2. The liquid is sent to the straight pipe 204, and the liquid is output to the secondary filter 3 through the straight pipe 204. The end of the straight pipe 204 away from the backwash filter 2 is fixedly connected with the secondary filter 3, and the liquid entering therein is subjected to secondary filtration through the secondary filter 3. The output end of the secondary filter 3 is fixedly connected with a transfer pipe 301. After the secondary filtration, the liquid in the secondary filter 3 is output to the transfer pipe 301. A tertiary filter 4 is arranged below the end of the transfer pipe 301 away from the secondary filter 3. After the filtration, the liquid to be filtered is further filtered through the tertiary filter 4. The filtration density of the backwash filter 2 is greater than that of the secondary filter 3. The secondary filter 3 has a greater filtration density than the three-stage filter 4. The bottom end of the feed barrel 1 is arranged in a hemispherical shell. A spiral blade 104 is fixed on the inner wall of the feed barrel 1. A central axis 105 is fixed through the center of the spiral blade 104. The spiral blade 104 increases its strength through the central axis 105. At the same time, after the spinning wastewater to be filtered is transported to the feed barrel 1, it is spirally transported in the feed barrel 1. Impurities in the wastewater deposited at the bottom of the feed barrel 1 are concentratedly transported to the vertical feed pipe 101 by the vortex. A transparent box 402 is fixedly connected to the center of the bottom end of the three-stage filter 4. A laser pen 403 is fixed to the center of one side of the transparent box 402. The three-stage filter 4 is placed in the transparent box 402.

[0026] Specifically, an electric control valve 102 is fixed to the upper part of the peripheral side of the vertical material pipe 101, and the two bypass pipes 103 are arranged parallel to each other. When the vertical material pipe 101 is working, the electric control valve 102 controls the on-off of the liquid in the feeding barrel 1 to be transported to the bypass pipe 103.

[0027] Furthermore, a cleaning waste liquid port 201 is fixedly connected to the middle of the peripheral side of the backwash filter 2, and the cleaning waste liquid port 201 is horizontally arranged. The end of the cleaning waste liquid port 201 away from the backwash filter 2 is connected to the sewage discharge equipment. When the backwash filter 2 is backwashed, the waste water after flushing is transported to the external sewage discharge equipment through the cleaning waste liquid port 201.

[0028] Furthermore, a cleaning liquid inlet 202 is fixedly connected to the rear side of the backwash filter 2 at an angle, and an electric control valve 205 is fixed to the side of the curved pipe 203 and the straight pipe 204 at one end close to the backwash filter 2. The end of the cleaning liquid inlet 202 away from the backwash filter 2 is connected to the pipeline for conveying flushing water, and the flushing water is conveyed to the backwash filter 2. The curved pipe 203 and the branch pipe both control the on-off of the corresponding backwash filter 2 output through the electric control valve 205.

[0029] The operation process of this embodiment is as follows: when working, first determine whether the backwash filter 2 located at the top or the backwash filter 2 located at the bottom is performing the filtering action. When the backwash filter 2 located at the top is performing the filtering action, open the second electric control valve 205 on the bent pipe 203, and keep the second electric control valve 205 on the straight pipe 204 closed, and then open the first electric control valve 102. At this time, the liquid to be filtered is transported to the bypass pipe 103 located at the top through the vertical material pipe 101, and then transported to the backwash filter 2 through the bypass pipe 103. After preliminary filtration, it is transported to the straight pipe 204 through the bent pipe 203, and then transported to the secondary filter 3 through the straight pipe 204. When the backwash filter 2 located at the top has been working for a certain period of time (such as one hour), close the second electric control valve 205 on the bent pipe 203 and keep the second electric control valve 205 on the straight pipe 204 closed. When the electric control valve 205 on the straight pipe 204 is started, the liquid to be filtered transported in the vertical material pipe 101 is transported to the backwash filter 2 through the bypass pipe 103 located below, and is directly transported to the secondary filter 3 through the straight pipe 204. When the backwash filter 2 is replaced, the idle backwash filter 2 can transport the cleaning water to the backwash filter 2 through the cleaning liquid inlet 202, and the cleaning water is discharged to the treatment equipment through the cleaning waste liquid port 201 after flushing. When the waste water is transported to the feeding barrel 1, it first passes through the spiral blade 104. After the waste water passes through the spiral blade 104, it is spirally transported to generate a vortex at the bottom end of the feeding barrel 1, so that the waste water impurities deposited at the bottom end of the feeding barrel 1 are concentrated and transported to the vertical material pipe 101, so as to prevent the impurities in the waste water from being deposited in the feeding barrel 1. Specific embodiment 2

[0030] See also Figure 1 , 4 5. On the basis of the specific embodiment 1, the upper part of the transfer delivery pipe 301 is in an inverted U-shape, and a pressure sensor 302 is fixed through the middle part of the U-shaped circumference of the transfer delivery pipe 301. When the transfer delivery pipe 301 is working, the pressure of the liquid transported therein is measured by the pressure sensor 302 and transmitted to the control device.

[0031] Specifically, the input end of the tertiary filter 4 is fixedly connected to an input pipe 401, the top of the input pipe 401 is fixedly connected to the end of the transfer pipe 301 away from the secondary filter 3, and the bottom center of the transparent box 402 is fixedly connected to an output pipe 404. The bottom end of the output pipe 404 is connected to a device that uses the filtered liquid. The liquid transported by the transfer pipe 301 is transported to the tertiary filter 4 through the input pipe 401. After being filtered by the tertiary filter 4, the wastewater is transported to the transparent box 402. Under the inspection of the transparent box 402 and the laser pen 403, the Tyndall phenomenon of the wastewater is observed to determine the filtration condition of the spinning wastewater, and then the wastewater is output to the use equipment through the output pipe 404.

[0032] The operation process of this embodiment is as follows: when working, after the secondary filter 3 filters the liquid filtered in the backwash filter 2, the liquid is transported to the transfer pipe 301, and then transported to the input pipe 401 through the transfer pipe 301. The liquid transported by the transfer pipe 301 is transported to the tertiary filter 4 through the input pipe 401. After being filtered by the tertiary filter 4, the wastewater is transported to the transparent box 402. The laser pen 403 on one side of the transparent box 402 is turned on to observe the Tyndall phenomenon of the wastewater, determine the clarity of the wastewater, determine the filtering condition of the wastewater, and output it to the use equipment through the output pipe 404. At the same time, when the transfer pipe 301 is working, the pressure of the liquid transported therein is measured by the pressure sensor 302 and transmitted to the control device, so as to conveniently determine the pressure state in the filtering equipment.
