[0019] In order to elaborate on the technical scheme adopted by the utility model to achieve the predetermined technical purpose, the technical scheme in the embodiment of the utility model will be clearly and completely described in combination with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a partial embodiment of the utility model, not all of the embodiments, and the technical means or technical features in the embodiment of the utility model can be replaced without paying creative labor. The utility model will be described in detail with reference to the drawings and in combination with the embodiments.

[0020] like Figure 1 , Figure 2 As shown, a water mist dust removal device for finishing rolling of hot-rolled threaded steel of the utility model comprises a movable sleeve 1, an upper water mist dust removal nozzle mechanism 2 and a lower water mist dust removal nozzle mechanism 3, the two ends of the movable sleeve 1 are respectively sleeved on the connecting port of the guide 4, the upper water mist dust removal nozzle mechanism 2 and the lower water mist dust removal nozzle mechanism 3 are respectively arranged on the upper side and the lower side of the movable sleeve 1, the upper water mist dust removal nozzle mechanism 2 and the lower water mist dust removal nozzle mechanism 3 respectively comprise a main pipeline 5, a columnar distribution cavity 6 and three spray pipes 7, the main pipeline 5 vertically passes through the upper side and the lower side of the movable sleeve 1 and is arranged on the upper side and the lower side of the movable sleeve 1, the columnar distribution cavity 6 is a horizontally arranged cylinder, the upper side of the columnar distribution cavity 6 is connected with one end of the main pipeline 5, one end of the three spray pipes 7 is connected with the lower side of the columnar distribution cavity 6, and the other end of the spray pipe 7 is provided with a nozzle and the nozzle faces the rolled steel surface.

[0021] Since the shape of the rolling rollers for rolling steel usually alternates between round and oval, the width of the rolled steel will be wider after being rolled into an oval shape.

[0022] like Figure 5 As shown, in one embodiment of the utility model, three spray pipes 7 are arranged in the vertical direction. This structure is suitable for the red steel of the elliptical roller. At this time, the cross section of the red steel is elliptical and the width is relatively wide. The three spray pipes 7 are arranged vertically and in parallel, which can cover a wide range and ensure that the upper and lower sides of the red steel can be sprayed.

[0023] like Figure 4As shown, in another embodiment of the utility model, one of the three spray pipes 7 is arranged in the vertical direction, and the other two spray pipes are symmetrically arranged on both sides of the vertically arranged spray pipe, and the other two spray pipes are arranged to be inclined inward. The two outer spray pipes are inclined inward, so that the spray water beams of the three spray pipes are bundled and contracted inward, so that when the red steel is rolled into a round shape with a small width, it is ensured that the spray pipes can spray on the upper and lower sides of the red steel.

[0024] Four long bolts 8 are respectively arranged at both ends of the movable sleeve 1. The four long bolts 8 are divided into two groups and are respectively arranged on the upper side and the lower side of the movable sleeve 1. Each group of two long bolts 8 are symmetrically distributed on both sides of the upper side or the lower side of the end of the movable sleeve 1. The movable sleeve 1 is provided with threaded holes matching the long bolts 8. The long bolts 8 are inserted into the threaded holes of the movable sleeve 1 one by one and are threadedly connected with the movable sleeve 1. In this way, the two ends of the movable sleeve 1 are sleeved on the connecting port of the guide, and then the end of the movable sleeve 1 is fixed to the guide by the upper and lower four bolts 8. Of course, the movable sleeve can be fixed by setting an additional bracket, and its specific fixing form is not limited.

[0025] The upper and lower sides of the movable sleeve 1 are provided with mounting holes, and the mounting plate 9 is detachably fixed to the mounting holes of the upper and lower sides of the movable sleeve 1 by means of locking bolts 10. Through the structure of the mounting plate 9, the main pipeline 5 can be inserted from the lower side of the mounting plate 9. After installation, the mounting plate 9 is fixed to the mounting hole of the movable sleeve 1, which facilitates the installation of the spray pipe.

[0026] An up-down adjustment fixing mechanism is provided between the main pipeline 5 and the mounting plate 9. The up-down adjustment fixing mechanism comprises a conical seal 11 and a screw cap 12. A through hole matching the outer diameter of the main pipeline 5 is provided on the mounting plate 9. A conical hole matching the conical seal 11 is provided at the upper end of the through hole. A cylindrical barrel 13 protruding from the upper surface of the mounting plate 9 is provided at the upper end of the conical hole. An external thread is provided on the outer side of the cylindrical barrel 13. The screw cap 12 is an inverted cylinder structure and an internal thread matching the external thread of the cylindrical barrel 13 is provided on the inner side wall of the screw cap 12. The screw cap 12 is sleeved on the outer side of the cylindrical barrel 13 and is threadedly connected to the cylindrical barrel 13. A through hole matching the main pipeline 5 is provided on the upper side surface of the screw cap 12. In this way, the screw cap 12 is screwed and fixed on the outside of the cylindrical tube 13 by screwing. During the screwing process, the screw cap 12 forms a downward extrusion force through the upper side facing the conical seal 11. The conical surface of the lower end of the conical seal 11 cooperates with the conical surface of the conical hole to form an inward extrusion force, so that the conical seal 11 locks the inner main pipe 5. When the height of the main pipe 5 needs to be adjusted, the screw cap 12 is loosened to prevent the conical seal 11 from being squeezed, and the inner main pipe 5 can easily slide up and down in the conical seal 11 for adjustment.

[0027] The conical seal 11 is made of heat-resistant rubber, which can ensure its service life and effect in the high temperature and high heat environment of steel rolling.

[0028] The utility model installs upper and lower two groups of water mist dust removal nozzle mechanisms at the guide and guard joint through a movable sleeve to completely remove the smoke and dust at the joint. The movable sleeve is easy to install, and the water mist dust removal nozzle mechanism can completely cover the upper and lower surfaces of the red steel. The installation and disassembly structure is reasonable and convenient, and the nozzle height can be adjusted up and down to ensure the smoke and dust removal effect.
