Description

Technical Field

[0001] This utility model belongs to the field of cold rolling mills, and in particular relates to an anti-clogging emulsion spraying device. Background Technology

[0002] A cold rolling mill is a new type of steel bar cold rolling processing equipment, mainly used to cold roll hot-rolled slabs to produce high-quality cold-rolled steel plates. These steel plates have high strength, good formability, excellent corrosion resistance and excellent appearance quality, and are therefore widely used in industries such as steel, non-ferrous metals, automobiles, construction, and metallurgy. During the rolling process, a large frictional force is generated between the rolls and the strip. The friction between the rolls and the strip, as well as the deformation of the metal, generates a large amount of heat. In order to cool, lubricate and control the roll profile, and at the same time extend the service life of the rolls, it is necessary to spray emulsion on the surface of the mill roll system and the strip.

[0003] Comparing with Chinese Patent No. CN213856328U, an emulsion spraying device for an anti-clogging cold rolling mill is disclosed, comprising a storage box, a nozzle housing, a spray pipe, a first drive motor, a bearing, a second drive motor, a semiconductor cooler, and a copper sheet. The discharge end of the storage box is fixedly connected to the nozzle housing via a drain pipe. The inner wall of the nozzle housing is fixedly sleeved with a bearing. The spray pipe is inserted into the inner cavity of the nozzle housing and penetrates the middle of the inner cavity of the bearing. The inner wall of the inlet of the spray pipe is provided with spiral blades. The outlet of the spray pipe is located on the outer wall of the nozzle housing, and a second gear is fixedly sleeved on the outer wall of the outlet of the spray pipe. The arc-shaped outer wall of the storage box is fixedly connected to the first drive motor, and the outer wall of the shaft of the first drive motor is fixedly sleeved with a first gear. The first gear meshes with the second gear.

[0004] The aforementioned patent cannot filter out fine impurities in the emulsion stream, which can easily cause nozzle clogging after prolonged use. Therefore, a new device needs to be designed. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 An anti-clogging emulsion spraying device includes an inlet assembly for connecting to and diverting a control connection pipeline, an spraying assembly for spraying emulsion and shutting off a standby pipeline on one side of the inlet assembly, and two filter assemblies symmetrically arranged between the inlet assembly and the spraying assembly for filtering impurities and triggering an alarm by elastic pressing.

[0025] In this embodiment: the liquid inlet assembly includes a liquid inlet pipe 101, a switching valve 102 is installed at one end of the liquid inlet pipe 101, and two diversion pipes 103 are symmetrically installed on the front and rear sides of the switching valve 102. A connector 104 is provided at the end of the diversion pipe 103 away from the switching valve 102. In use, the switching valve 102 connects one side of the diversion pipe 103, and then the emulsion is pumped into the liquid inlet pipe 101, so that it enters the subsequent pipeline through the corresponding connector 104.

[0026] In this embodiment: the filter assembly includes a filter tube 201, a connecting sleeve 202 at one end of the filter tube 201, a magnetic ring 203 slidably installed inside the filter tube 201, a protective tube 205 installed inside the magnetic ring 203, a filter screen 204 installed on the side of the protective tube 205 near the magnetic ring 203, a spring 206 installed outside the protective tube 205, and a trigger assembly outside the filter tube 201. The trigger assembly includes an iron ring 207, a fixing ring 208 on one side of the iron ring 207, a trigger button 209 installed on the side of the fixing ring 208 near the iron ring 207, and an alarm light 210 installed on the side of the fixing ring 208 away from the trigger button 209. 07 is slidably connected to the filter tube 201, the fixing ring 208 is fixedly connected to the filter tube 201, and the connector 104 is plugged and sealed to the connecting sleeve 202. When it passes through the filter tube 201, the fine impurities in the emulsion flow are blocked by the filter screen 204. As the number of blocked fine impurities increases, the filter screen 204 will gradually become clogged, thereby pushing the magnetic ring 203 along the protective tube 205 to compress the spring 206, and driving the iron ring 207 to move towards the trigger button 209 on the fixing ring 208. Pressing the trigger button 209 will make the alarm light 210 light up. At the same time, the switching valve 102 will switch gears to switch the emulsion flow to another pipeline to avoid blockage and affect the spraying.

[0027] In this embodiment: the spraying assembly includes a nozzle 301, a confluence pipe 302 is installed on one side of the nozzle 301, and two control valves 303 are symmetrically arranged at the end of the confluence pipe 302 away from the nozzle 301. A connecting pipe 304 is provided on the side of the control valve 303 away from the confluence pipe 302. The connecting pipe 304 is a rubber hose and is sealed to the filter pipe 201. In use, the control valve 303 on the connecting pipe of the switching valve 102 is opened and the other control valve 303 is closed, so that the emulsion flows through the connecting pipe 304 and the control valve 303 on the connecting pipe into the confluence pipe 302 and is sprayed out from the nozzle 301.

[0028] Working principle: Both the switching valve 102 and the control valve 303 are solenoid valves. In use, the switching valve 102 connects to the front branch pipe 103 and opens the front control valve 303, while closing the rear control valve 303. At this time, the emulsion is pumped into the inlet pipe 101, and under the control of the switching valve 102, it sequentially passes through the front branch pipe 103, connector 104, connecting sleeve 202, filter pipe 201, connecting pipe 304, and control valve 303 before entering the confluence pipe 302 and being sprayed out from the nozzle 301 to cool and lubricate the cold-rolled steel plate. When the emulsion flows through the filter pipe 201, fine impurities in the emulsion are filtered out. As the amount of fine impurities blocked increases, the filter screen 204 will gradually become clogged, thus pushing the magnetic ring 203 along the protective tube 205 to compress the spring 206, and driving the iron ring 207 to move towards the trigger button 209 on the fixed ring 208. Pressing the trigger button 209 will illuminate the alarm light 210. At the same time, the switching valve 102 will switch positions, connecting the downstream pipeline and closing the front control valve 303. The rear control valve 303 will open, closing the front pipeline to prevent blockage. At this time, the connector 104 can be pulled out of the connecting sleeve 202 to clean the filter screen 204 in the front filter tube 201.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
