Description

Technical Field

[0001] The utility model relates to the technical field of high-pressure water cleaning, in particular to a dephosphorization cleaning mechanism with adjustable width. Background Art

[0002] High-pressure water is the main method for descaling hot-rolled plates in steel plants. This is limited by the fact that the arrangement of the water nozzles on the descaling manifold is fixed, the use of the nozzles is fixed, and the width of the high-pressure water spray is also fixed. Different widths are used in the manufacture of hot-rolled plates. The existing nozzle arrangement width is designed according to the widest plate. Therefore, in the dephosphorization process, when the width of the spray water flow remains unchanged, part of the water flow does not participate in the cleaning process when cleaning the narrower plates, resulting in water flow power loss and water waste. Utility Model Content

[0007] A dephosphorization and cleaning mechanism with adjustable width comprises a manifold and a plurality of high-pressure nozzles evenly distributed along the length direction of the manifold, the high-pressure nozzle comprises a valve sleeve passing through the manifold and fixed on the manifold, a liquid inlet is provided at a portion of the valve sleeve located inside the manifold, a remote control valve for controlling the opening and closing of the liquid inlet is provided at one end of the valve sleeve located outside the manifold, and a replaceable nozzle structure is provided at the other end of the valve sleeve located outside the manifold.

[0008] Preferably, the remote control valve comprises a control cylinder mounted on the valve sleeve and a valve core extending into the valve sleeve, wherein the control cylinder is used to drive the valve core to slide relative to the valve sleeve to open and close the liquid inlet.

[0014] (III) Beneficial effects

[0015] Several high-pressure nozzles are installed on the header according to the widest width of the plate, and each high-pressure nozzle is connected to the header by setting a liquid inlet on the valve sleeve. The water flow entering the header enters the valve sleeve through the liquid inlet and is sprayed out from the nozzle structure at high pressure to remove phosphorus and clean the passing plate;

[0016] At the same time, the opening and closing control of the liquid inlet is realized through the remote control valve.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] See also Figure 1-Figure 6 As shown, in the embodiment of the utility model, a dephosphorization cleaning mechanism with adjustable width is proposed, which is applied to the dephosphorization cleaning process and can be used as the power for water flow pressurization and delivery through a booster pump. Specifically, it includes a header 1 and a plurality of high-pressure nozzles 2 evenly distributed along the length direction of the header 1. After the water flow is collected through the header 1, it is sprayed outward at high pressure through the high-pressure nozzles 2 to form a high-pressure water jet, thereby achieving dephosphorization cleaning of the plate surface. Among them, the high-pressure nozzle 2 includes a valve sleeve 21 that passes through the manifold 1 and is fixed on the manifold 1. The valve sleeve 21 is provided with a liquid inlet 22 at a position located in the manifold 1. The end of the valve sleeve 21 located outside the manifold 1 is provided with a remote control valve 23 for controlling the opening and closing of the liquid inlet 22, and the other end of the valve sleeve 21 located outside the manifold 1 is provided with a replaceable nozzle structure 24; after the valve sleeve 21 is fixed to the manifold 1 by welding or the like, water entering the manifold 1 can only enter the valve sleeve 21 through the liquid inlet 22, and form a high-pressure water jet outward through the nozzle structure 24, and the nozzle structure 24 can use existing products.

[0028] Specifically, the number of high-pressure nozzles 2 installed on the manifold 1 is configured according to the widest width of the plate that can be cleaned. When the width of the plate becomes narrower, the liquid inlet 22 in the corresponding high-pressure nozzle 2 is closed by the remote control valve 23 to change the width of the water jet, thereby avoiding waste of water flow and ensuring that the water jet pressure is not lost.

[0029] The remote control valve 23 can be controlled online, so there is no need to replace the cleaning mechanism. It is only necessary to control the water output of the corresponding high-pressure nozzle 2 when the width of the plate changes, so as to achieve water jet width adjustment based on the change of the plate width.

[0030] The remote control valve 23 includes a control cylinder 231 installed on the valve sleeve 21 and a valve core 232 extending into the valve sleeve 21. The control cylinder 231 is used to drive the valve core 232 to slide relative to the valve sleeve 21 to open and close the liquid inlet 22. The control cylinder 231 moves the valve core 232 in the valve sleeve 21 to realize the opening and closing control of the liquid inlet 22. Specifically, the control cylinder 231 can also be a linear motor, a hydraulic cylinder, etc., so as to realize remote control of corresponding actions.

[0031] At the same time, since the valve core 232 can move relatively in the valve sleeve 21, it is necessary to seal the valve core 232 during the movement to prevent leakage. Specifically, a press sleeve 233 is provided in the valve sleeve 21, and the press sleeve 233 and the valve core 232 are in sliding sealing cooperation. The press sleeve 233 is used to seal the part of the valve sleeve 21 where the valve core 232 is installed, and it can ensure that the valve core 232 can move in the press sleeve 233 to form a sliding sealing cooperation.

[0032] Specifically, the valve sleeve 21 is installed with a nozzle connector 25 through a first nut 26, the nozzle structure 24 is inserted into the nozzle connector 25, the nozzle structure 24 has a positioning portion 240 abutting against the insertion port of the nozzle connector 25, and the nozzle connector 25 is provided with a second nut 27 for locking the nozzle structure 24; after the nozzle connector 25 is installed on the valve sleeve 21, the nozzle structure 24 can be inserted and positioned, and the positioning portion 240 and the opening part of the nozzle connector 25 are used to achieve limited cooperation, and the nozzle structure 24 is locked by the second nut 27.

[0033] Thus, the nozzle structure 24 can be disassembled for maintenance or replacement according to the frequency of use.

[0034] In order to provide good support for the valve sleeve 21 after the remote control valve 23 is installed, support blocks 3 are provided at intervals on the manifold 1, support plates 4 are fixed on the support blocks 3, and the valve sleeve 21 is limitedly installed on the support plate 4. After the support blocks 3 are fixed on the manifold 1 and a support structure is formed with the support plate 4, the valve sleeve 21 is stably supported, thereby preventing the valve sleeve 21 from being deformed.

[0035] At the same time, a limiting hole 5 is opened on the support plate 4, and a limiting step 6 is provided on the valve sleeve 21. The diameter of the limiting step 6 is larger than the diameter of the limiting hole 5. After the limiting step 6 is limited at the limiting hole 5, the support plate 4 can support the valve sleeve 21, further avoiding the risk of deformation caused by installing the remote control valve 23 at the corresponding part.

[0036] At the same time, a protective cover 7 for covering the control cylinder 231 is installed on the support plate 4. The control cylinder 231 is covered and protected by the protective cover 7, thereby avoiding the risk of damage to the control cylinder 231 caused by external water splashing.
