The lead screw sliding table 29 is a prior art, and the sliding end thereof can slide in the front-rear direction, so that the spray pipe 1 moves in the front-rear direction.

[0044] The lower end of the second side plate 10 is fixedly installed with a track plate 31, the lower surface of the track plate 31 is in sliding connection with a guide rail 30, and the guide rail 30 is fixedly installed on the side surface of the surrounding plate 33.

[0045] As shown in Figure 2 , Figure 3 The upper surface of the spray pipe 1 is fixedly connected with a guide strip 2, and the inner top surface of the sleeve frame 8 is in sliding fit with the upper surface of the guide strip 2. The design of the guide strip 2 further improves the stability of the sleeve frame 8 when sliding.

[0046] A synthetic fiber biochemical treatment process is also proposed, which is carried out by using the above-mentioned spray head, and includes the following steps:

[0047] S1, the front end of the water inlet pipe 34 is connected to the sewage discharge pipeline, and the port of the liquid injection port 35 is connected to the medicament supply pipeline;

[0048] S2, the sewage in the water inlet pipe 34 is dispersed by the flow guide block 23 to form a water curtain, and the medicament in the ports of the plurality of insert frames 4 is sprayed to fully contact with the water curtain, and then mixed and discharged from the rear end of the water passage 32;

[0049] S3, the sewage discharged from the water passage 32 enters the sedimentation tank for sedimentation overflow, and then enters the aeration tank, and the synthetic fiber organic matter is degraded by aerobic microorganisms under aerobic conditions.

[0050] The front end of the water inlet pipe 34 is connected to the sewage discharge pipeline, and the port of the liquid injection port 35 is connected to the medicament supply pipeline, the sewage in the water inlet pipe 34 is dispersed by the flow guide block 23, the sewage is dispersed by the guide of the inclined curved surface 24, and the water flow above is guided by the top inclined surface 25 to prevent the sewage from splashing too high and damaging the water curtain formed in the rear, the water curtain reaches the lower side of the spray pipe 1, the medicament in the ports of the plurality of insert frames 4 is sprayed to fully contact with the water curtain, and then mixed and discharged from the rear end of the water passage 32, the sewage discharged from the water passage 32 enters the sedimentation tank for sedimentation overflow, and then enters the aeration tank, and the synthetic fiber organic matter is degraded by aerobic microorganisms under aerobic conditions, and has the function of assisting the formation of the sewage water curtain, so that the mixing of the medicament and the sewage is more sufficient.

[0051] In long-term use, fiber impurities are easily accumulated on both sides of the water curtain, and the impurities adhere to the surface of the water passage 32. At this time, by controlling the operation of the first motor 12, the first lead screw 11 is rotated, and then the sleeve frame 8 is transversely moved to one side. After transverse movement, the nozzle 1 is controlled to move backward by the lead screw sliding table 29, that is, the flow guide block 23 is moved backward. Due to the guiding action of the rear curved surface 26, the impurities contact the rear curved surface 26 towards the middle of the upper surface close to the water passage 32. Then, the flow guide block 23 is controlled to move forward to reset, and then the flow guide block 23 is transversely moved to the other side and moved backward to clean the impurities. After the impurities accumulated on both sides are gathered to the middle by the twice backward movement of the flow guide block 23, the impurities can be discharged from the rear end of the water passage 32 under the impact of the subsequent sewage. Therefore, the accumulated fiber impurities can be quickly cleaned.

[0052] In the cleaning of fiber impurities, when the sleeve frame 8 is transversely moved, the scraper 27 will contact the beveled edge 28, and then push the insert frame 4 upward to ensure that the scraper 27 can fully contact the lower end of the insert frame 4 when transversely moving, so as to clean the port and prevent the port from accumulating medicine.

[0053] By controlling the operation of the second motor 20, the second lead screw 18 is rotated, and then the distance adjusting plate 19 is moved forward or backward, and then the forward and backward positions of the flow guide block 23 are changed, so as to ensure that the water curtain formed by the flow guide block 23 can be located below the nozzle 1, and prevent the water curtain below the nozzle 1 from not being formed or being scattered.

[0054] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application.
