Description

Technical Field

[0001] The utility model belongs to the field of steel rolling dust removal equipment, and more specifically relates to a spray high-pressure nozzle structure. Background Art

[0002] In the bar rolling production line, the main work is to roll the incoming steel billet into the required shape. However, after the steel billet leaves the heating furnace and enters the transport roller, it is affected by the ambient temperature, causing the surface of the steel billet to cool down rapidly and the surface of the steel billet to undergo an oxidation reaction with the oxygen in the air, resulting in a thicker oxide layer on the surface of the steel billet. If the thick oxide layer is not removed, it will enter the rolling process and be rolled into the formed steel, which will cause internal defects or external cracks in the formed steel. However, since the oxide layer is thick, it requires the use of high-pressure wind or water to remove it. Generally, high-pressure water dephosphorization devices are used in production lines. On the one hand, high-pressure water spraying can remove the oxide on the surface of the steel billet. On the other hand, the oxide layer is broken under the impact of high-pressure water, generating a large amount of dust. and floating objects, so water also has a certain dust reduction effect. Therefore, it can be said that any steel company cannot do without high-pressure water dephosphorization equipment. However, if you want the high-pressure water dephosphorization equipment to spray high-pressure water, not only does it require a high system pressure, but it also requires a suitable nozzle structure, so that a better dephosphorization effect can be achieved. On the other hand, for steel companies that use hot metal sawing, the metal saw blade not only needs water to cool the teeth and saw surface, but also needs water to flush away the cuttings caught in the metal saw teeth. Therefore, it also needs to have water with a certain pressure. It also faces the problem of not only a high system pressure, but also a suitable nozzle structure, so that the cooling and slag removal effects can be good. In any case, we need to design a nozzle device that can not only solve special problems but also general problems.

[0003] Most of the nozzles used in the existing bar production lines are imported from abroad. The cost of each nozzle is very high, which is very unfavorable for the company's policy of reducing costs and increasing efficiency. In addition, the nozzle structure is easy to clog. Once clogged, it is very difficult to clean. In most cases, it is scrapped. On the other hand, the nozzle can only be welded to the branch pipe at the installation position. There is no threaded connection structure on the nozzle device. To replace the nozzle device, the welding position can only be cut. Therefore, this design is not conducive to equipment maintenance and repair. Not only is the service life short, but the maintenance efficiency is low. In addition, the nozzle is under the high-pressure impact of water for a long time, resulting in the filtration structure in the nozzle cannot be disassembled, so the inside cannot be cleaned.

[0035] The base has a first external thread and a second external thread respectively disposed on the outer peripheral surfaces of both ends;

[0036] A nozzle, one end of which is inserted into one end of the base, a first clamping portion is provided at the middle of the outer periphery of the nozzle, one end of the first clamping portion is matched with one end of the base, a first internal thread is provided at one end of the nozzle, and a through hole is provided at the other end of the nozzle;

[0037] The nozzle is arranged in the nozzle head, the end of the nozzle is engaged with the hole wall of the via hole, and one end of the nozzle is connected with the via hole;

[0038] A stepped supercharger is arranged in the nozzle, and one end of the stepped supercharger is connected to the other end of the nozzle;

[0040] The fixing nut has a second internal thread matched with the first external thread at one end, and a second clamping portion is provided on the inner periphery of the fixing nut, and the inner peripheral surface of the second clamping portion matches with the outer peripheral surface of the first clamping portion.

[0041] Specifically, the spray high-pressure nozzle structure includes a base, a nozzle, a nozzle, a stepped supercharger, a filter supercharger head and a fixed nut, wherein the nozzle and the stepped supercharger are sequentially placed in the nozzle, and the nozzle can be blocked and limited by the hole wall of the through hole, and the filter supercharger head is installed at one end of the stepped supercharger, so that the filter supercharger head is screwed to the nozzle, and the nozzle and the stepped supercharger can be confined in the nozzle; then, the nozzle assembly with the internal structure connected is placed in the base, and the first clamping part is used to limit the end face of the base; finally, the fixed nut is connected to the base along the insertion direction of the nozzle assembly, and the second internal thread is screwed to the first external thread, so that the second clamping part can firmly press the first clamping part on the base, and the spray high-pressure nozzle structure is assembled. In the nozzle structure, a stepped supercharger and a filter supercharger head are set, so that internal pressurization and filtration of the incoming water can be achieved.

[0042] Optionally, the diameter of one end of the nozzle is smaller than the diameter of the other end of the nozzle.

[0043] Optionally, a diameter of one end of the stepped supercharger is smaller than a diameter of the other end of the stepped supercharger.

[0044] Optionally, a flat water outlet is provided at one end of the nozzle.

[0045] Specifically, in the nozzle, the diameter of one end of the nozzle connected to the through hole is smaller than that of the end connected to the staged supercharger, so that the water pressure is increased by changing the cross-sectional area; in addition, the end of the staged supercharger connected to the nozzle is smaller than that of the end connected to the filter supercharger head, so that a vortex supercharger zone is formed in the staged supercharger, which can further increase the water outlet pressure of the nozzle; and a flat water outlet is provided at the end of the nozzle connected to the through hole, so that the water outlet can be deformed into a fan shape, which not only has a high water outlet pressure but also has a large contact area with the object.

[0046] In one embodiment, a section of equal-diameter pipeline is provided at one end of the nozzle close to the through hole, and a tapered pipeline is provided at one end of the nozzle away from the through hole, and the small-mouth end of the tapered pipeline is connected to the diameter pipeline; the internal pipeline structure of the nozzle is similar to that of the stepped supercharger. In addition, at the connection between the stepped supercharger and the nozzle, the caliber of the stepped supercharger is smaller than the caliber of the nozzle.

[0047] Optionally, the first clamping portion and the second clamping portion are conical.

[0048] Specifically, the plane of the first clamping part on the nozzle fits with the end face of the base, and the conical surface of the second clamping part of the fixing nut is parallel to the conical surface of the first clamping part of the nozzle. The longer the screw connection length between the fixing nut and the base is, the tighter the conical surface of the second clamping part fits with the first clamping part, so that the nozzle can be firmly fixed on the base to ensure the overall strength of the nozzle structure. The contact surface between the nozzle and the fixing nut adopts a conical surface. By tightening the fixing nut, the nozzle can be tightly installed on the base and pressure relief caused by water leakage can be prevented.

[0049] Optionally, a first clamping surface is provided on the outer peripheral surface of one end of the nozzle, and a second clamping surface is provided on the outer peripheral surface of the filter booster head.

[0050] Specifically, a threaded connection is adopted between the filter booster head and the nozzle, and the nozzle and the extension booster are pressed into the nozzle by continuously screwing the filter booster head in. A first clamping surface and a second clamping surface are arranged on the nozzle and the filter booster head, so that the two can be tightened with a suitable tool.

[0051] Optionally, a circular boss is provided at one end of the nozzle, and two protruding blocks are correspondingly provided on the boss, the protruding blocks are semicircular, and a through hole is formed on the inner circumference of the boss in a space without the protruding blocks.

[0052] Specifically, at the connection between the nozzle and the water outlet of the nozzle, a boss and two semicircular raised blocks are arranged on the nozzle. The relative position of the raised blocks is a flat end. A through hole is formed at the position of the boss between the two raised blocks. The water of the nozzle is sprayed out from the through hole. The water outlet of the nozzle is hidden inside the raised block and the boss, thereby effectively protecting the water outlet position of the nozzle.

[0053] Optionally, a filter hole is provided on the inner side of the other end of the filter booster head, and the filter hole is in a long strip shape.

[0054] Specifically, there are long strips of filter holes on the filter booster head, and the interior of the filter booster head is set to a conical shape, which can play a role in diversion and reduce the impact of the incoming water pressure on the filter booster head. When the high-pressure nozzle structure is installed on the pipeline branch pipe, when water with a certain pressure flows into the branch pipe, the water flows into the high-pressure nozzle structure through the filter hole through the obstruction of the branch pipe wall. The filter hole not only plays a filtering role but also plays a preliminary pressurization role. When the water continues to enter the interior, it is pressurized for the second time through the staged supercharger, and then for the third time through the vortex area formed between the nozzle and the staged supercharger, and finally sprayed out from the flat water outlet of the nozzle.

[0055] Optionally, the nozzle is made of hard alloy or ceramic.

[0056] Specifically, the nozzle is used to install the nozzle and the staged supercharger, among which the nozzle mainly bears the impact of high-pressure water, so the nozzle is made of carbide or ceramic material to improve the overall strength of the nozzle, avoid the nozzle outlet diameter becoming larger under the impact of high-pressure water, affect the water pressure, and avoid difficulties in the installation of the nozzle and the nozzle.

[0057] Optionally, the stepped supercharger is made of hard alloy or ceramic.

[0058] Specifically, the staged supercharger is also subjected to high pressure and water impact when working, so the staged supercharger should also be made of wear-resistant materials, such as cemented carbide or ceramics, so that the staged supercharger can form a structure with a changing cross-section, which can play a role in boosting while bearing water pressure.
