[0001] The invention relates to the technical field of sewage treatment, and in particular to a printing wastewater circulation separation treatment device. Background Art

[0002] Printing is a technology that transfers ink from originals such as text, pictures, photos, anti-counterfeiting, etc. to the surface of paper, fabrics, plastics, leather and other materials through processes such as plate making, inking and pressurization for the purpose of mass reproduction.

[0003] The wastewater generated during the printing process needs to be treated before it can be discharged.

[0031] See also Figure 1-Figure 7The present invention provides a technical solution: a printing wastewater circulation separation treatment device, comprising a fixed water tank 1, a transmission plate 2 arranged at the upper end of the fixed water tank 1, and a discharge pipe 4 installed on the outer side of the fixed water tank 1, a separation box 12 is installed at the top of the fixed water tank 1, an air compressor 13 is installed on one side of the bottom of the separation box 12, the transmission plate 2 is movably clamped inside the separation box 12, the transmission plate 2 is located directly above the air compressor 13, a positioning plate 21 is installed at one end of the transmission plate 2, the positioning plate 21 is made of plastic and has a plurality of rectangular grooves opened therein, and a separation frame 3 is installed inside the rectangular groove, and the separation frame 3 is used for separating suspended solid impurities;

[0032] The discharge pipe 4 is installed at the bottom end of the fixed water tank 1 and is bent. The discharge pipe 4 is connected to the external transmission pipe. A positioning frame 11 is installed on the outer wall of the top of the fixed water tank 1. A ladder is installed at one end of the positioning frame 11. When the sewage needs to be treated, the sewage can be discharged from the upper end of the fixed water tank 1 with the help of external equipment. The sewage can be separated for the first time under the action of the separation frame 3, and the agent used to separate the suspended matter can be mixed in. At the same time, under the action of the air compressor 13, the transmission plate 2 can be pushed to move, which can stir the internal sewage and the agent to mix, and at the same time, the residual suspended matter in the sewage can be separated for the second time. In the subsequent sewage distribution process, the residual amount of impurities in the sewage can be observed with the help of the interception piece 44, so as to decide whether multiple screening treatments are needed.

[0033] like Figure 3 As shown, when sewage is purified by means of chemicals, the reaction speed of the chemicals is often slow. A pair of suspension shafts 22 are installed on the top of the transmission plate 2, and a pair of lifting pipes 23 are installed on the bottom of the transmission plate 2. The bottom of the lifting pipe 23 is connected to the output end of the air compressor 13. The lifting pipe 23 can be retracted and extended under the action of air pressure to push the transmission plate 2 to move inside the separation box 12. As the transmission plate 2 moves, it can drive the positioning plate 21 at one end to stir in the sewage, so that the sewage can react quickly with the chemicals during the stirring process, and the excess chemical impurities inside are precipitated out in the form of precipitation, which is convenient for subsequent separation and cleaning.

[0034] like Figure 4 As shown, a plurality of elastic rings 231 are installed on the side wall of the lifting tube 23. The elastic rings 231 are arranged in a uniform array on the outer wall of the lifting tube 23. A plurality of positioning shafts 24 are fixedly connected to the elastic rings 231. The positioning shafts 24 are made of stainless steel and are evenly arranged on the elastic rings 231. During the intermittent air supply process of the air compressor 13, the lifting tube 23 can be pulled to reset under the action of the positioning shafts 24 and the elastic rings 231.

[0035] like Figure 5As shown, in order to ensure that the impurities suspended in the sewage are separated and precipitated, the separation frame 3 is composed of a pair of rectangular frames, and limit blocks 31 are clamped at both ends of the separation frame 3. The limit blocks 31 are symmetrically arranged inside the rectangular frame. A pair of adsorption plates 34 are installed inside the separation frame 3. The adsorption plates 34 are clamped inside the rectangular grooves on both sides. A plurality of adsorption sheets are fixedly connected to the surface of the adsorption plates 34. A gap is provided between the adsorption plates 34 and the rectangular frame for the gushing sewage to flow back. With the help of the gap between the adsorption plates 34 and the rectangular frame, the sewage can be quickly dusted, and the internal sewage can be mixed with the agent during the circulation and stirring process, which can accelerate the reaction speed of the agent.

[0036] A pair of support frames 32 are installed at the top of the separation frame 3. The support frames 32 are symmetrically arranged. A plurality of positioning rods 33 are movably arranged on the support frames 32. The positioning rods 33 are arranged on the support frames 32 in a uniform array.

[0037] like Figure 6 As shown, the flocculent inside the sewage will continue to move with the water flow during the stirring process. A pair of clamping rings 35 are installed on the positioning rod 33. The clamping rings 35 are symmetrically arranged. One end of the clamping rings 35 on both sides is movably clamped with a blocking cover 36. The blocking cover 36 is bowl-shaped and has a fixing hole. The blocking cover 36 is movably clamped on the positioning rod 33. A plurality of reset shafts are fixedly connected to the clamping ring 35, and the reset shafts are made of rubber. A positioning hole is opened on the edge of the blocking cover 36, and the reset shaft is clamped inside the positioning hole.

[0038] A guide plate 37 is installed inside the blocking cover 36. The guide plate 37 is arc-shaped and is evenly arranged in an array inside the blocking cover 36. A plurality of drainage holes are opened on one side of the blocking cover 36, and the drainage holes and the guide plate 37 are staggered. A gap is provided between the guide plate 37 and the blocking cover 36. A plurality of adsorption rings 361 are installed at one end of the guide plate 37 located on the inner side of the blocking cover 36. As the water flow impacts the inside of the blocking cover 36, it can be transmitted under the action of the guide plate 37, and the internal sediment can be stuck between the adsorption rings 361, which can separate the internal sediment to prevent blockage in the subsequent transmission process. Moreover, as the water flow impacts, the blocking cover 36 can move on the positioning rod 33. With the action of the reset shaft, the excess sewage in the sediment can be drained under the action of inertia, which is convenient for subsequent unified cleaning and collection.

[0039] like Figure 7 As shown, a limit baffle 38 is installed between the limit blocks 31. The middle end of the limit baffle 38 is upwardly protruding. A plurality of drainage grooves 381 are provided at the protruding portion of the limit baffle 38. The drainage grooves 381 are used for water flow guidance and can guide the gushing sewage along the direction of the blocking cover 36. As the sewage is stirred, it can flow out along the drainage grooves 381 under the action of the limit baffle 38, and can impact the inside of the blocking cover 36.

[0040] like Figure 1 As shown, a sealing groove is provided on the discharge pipe 4, and a sealing plate 41 is installed inside the sealing groove, a reset rod 42 is installed at one end of the sealing plate 41, and a plurality of blocking plates 43 are fixedly connected to the reset rod 42. A gap is provided between the blocking plate 43 and the inside of the discharge pipe 4, which can block the sewage in the transmission process and control the discharge speed, so as to avoid the transmission speed being too fast and affecting the detection effect of the impurity content in the sewage.

[0041] like Figure 2 As shown, in order to avoid the situation where there are still a lot of dirt and debris remaining in the sewage, a plurality of retention pieces 44 are fixedly connected to the inside of the blocking plate 43, and the retention pieces 44 are in a continuously twisted shape. A plurality of grid adsorption pieces are fixedly connected to the retention pieces 44, which can discharge for ten to thirty seconds before a large amount of discharge. It can determine whether the sewage meets a reasonable standard based on the amount of sediment and dirt adsorbed on the retention pieces 44, and can perform simple detection, thereby controlling the circulation and separation treatment of the sewage to prevent the situation where a single screening effect is poor.

[0042] Working principle: First, when sewage needs to be treated, the sewage can be discharged from the upper end of the fixed water tank 1 with the help of external equipment, and the sewage can be separated for the first time under the action of the separation frame 3, and the agent used to separate the suspended matter can be mixed in. At the same time, under the action of the air compressor 13, the transmission plate 2 can be pushed to move, and the internal sewage and the agent can be stirred to mix, and the residual suspended matter in the sewage can be separated for the second time. In the subsequent sewage distribution process, the residual amount of impurities in the sewage can be observed with the help of the interception piece 44 to determine whether multiple screening treatments are needed. When the sewage enters the fixed water tank 1 under the action of the external equipment, the solid debris in the sewage can be separated under the action of the adsorption plate 34, and the separation can be simple, reducing the amount of subsequent agent addition;

[0043] Then, under the intermittent air supply of the air compressor 13, the lifting pipe 23 can push the transmission plate 2 and the positioning plate 21 at the top to move, so that the sewage inside can be quickly stirred, so that the medicine reacts with various chemical impurities in the sewage to precipitate, and as the sewage is stirred, it can be made to gush out along the drainage groove 381 under the action of the limit baffle 38, so that the sewage can impact the inside of the blocking cover 36, and can be transmitted under the action of the guide plate 37, and the internal sediment can be stuck between the adsorption rings 361, so that the internal sediment can be separated to prevent blockage in the subsequent transmission process, and with the impact of the water flow, the blocking cover 36 can move on the positioning rod 33, and with the action of the reset shaft, the excess sewage in the sediment can be dried under the action of inertia, which is convenient for subsequent unified cleaning and collection, and with the separated sewage, it can flow back along the gap between the adsorption plate 34 and the separation frame 3, so that the sewage can be circulated and separated to reduce the suspended impurities therein;

[0044] Finally, after the separation is completed, the internal sewage can be discharged quickly, and can be discharged for ten to thirty seconds before large-scale discharge. The amount of sediment and dirt adsorbed on the retention piece 44 can be used to determine whether the sewage meets reasonable standards. Simple testing can be performed to control the cyclic separation treatment of the sewage to avoid the situation where a single screening is unqualified and affects subsequent discharges.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
