Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a high-efficiency flushing and cooling nozzle for a disc saw blade. Background Art

[0002] High-efficiency flushing and cooling nozzles for disc saw blades are usually installed on disc saw equipment to cool the saw blades and workpieces to reduce friction and heat, improve cutting efficiency and workpiece surface quality, and improve the process structure and technology of flushing and cooling water nozzles for disc saw blades of large sawing machines on existing steel production lines.

[0003] The water nozzles currently on the market for flushing and cooling the surface of disc saws have a simple structure and a single function. When encountering metal sawn materials with high viscosity, more and more sticky metal chips will remain on the surface of the disc saws. In order to remove these chips in time, the flushing force of the jet can only be further increased. Therefore, it is necessary to increase the system water supply pressure. The increase in pressure will cause excessive water output from the nozzle (exceeding the design value), resulting in a waste of water resources. Due to the compact structure of the sawing machine, excessive flushing and cooling water cannot be discharged in time, causing multiple points of leakage in the equipment. Secondly, it will cause the disc saw blade to be overcooled or unevenly cooled in various parts, affecting its life; long-term high system water supply pressure or leakage will also have an adverse effect on the equipment's operating safety and the piping system and other electrical components of the equipment. For this reason, a high-efficiency flushing and cooling nozzle for disc saw blades is proposed to solve the above problems. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides a high-efficiency flushing and cooling nozzle for a disc saw blade, aiming to improve the nozzle in the prior art with smaller water consumption, stronger flushing ability and cooling performance, and a larger cooling coverage area, effectively reducing the number of nozzles installed in a small space and facilitating maintenance; at the same time, reducing the water and electricity load of the pipeline system and pressure supply equipment, saving energy and reducing consumption.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-efficiency flushing cooling nozzle for a disc saw blade, comprising a disc saw blade, an H-shaped steel is slidably connected to the outer periphery of the disc saw blade, and a plurality of nozzles are slidably connected to the outer periphery of the disc saw blade.

[0006] As a further description of the above technical solution:

[0007] A conveying roller is slidably connected to the bottom of the H-shaped steel.

[0008] As a further description of the above technical solution:

[0009] The outer periphery of the disc saw blade is slidably connected with H-shaped steel 2.

[0010] As a further description of the above technical solution:

[0011] A pressure water inlet is provided in the nozzle.

[0012] As a further description of the above technical solution:

[0013] A jet self-excited water cavity is provided in the nozzle.

[0014] As a further description of the above technical solution:

[0015] An annular air cavity is provided in the nozzle.

[0016] As a further description of the above technical solution:

[0017] A pressure water outlet is provided in the nozzle.

[0018] The utility model has the following beneficial effects:

[0019] 1. In the utility model, the fluid channel inside the nozzle enables it to generate pulse jets. Under the condition that the system supply pressure remains unchanged, the jet flushing force is increased by more than 30%.

[0020] 2. In the utility model, a jet air protection layer is added, and the air flow speed of the protection layer is adjusted to be equivalent to the water jet speed, which can effectively reduce the kinetic energy loss caused by the high-speed friction between the jet and the external atmosphere. At the same time, on the surface of the plate, the water jet and the protective air are mixed to produce cooling atomized water. The small-particle atomized water has a larger contact area, coverage volume and faster heat exchange capacity than continuous pure water, so that the nozzle has a stronger cooling capacity and a larger cooling coverage area. Under the premise of the same effect, the number of nozzles installed online can be directly reduced, reducing the water and electricity load of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-3 The utility model provides an embodiment: a high-efficiency flushing cooling nozzle for a disc saw blade, comprising a disc saw blade 2, an H-shaped steel 4 is slidably connected to the outer periphery of the disc saw blade 2, a plurality of nozzles 3 are slidably connected to the outer periphery of the disc saw blade 2, and a pressure water inlet 5 is opened in the nozzle 3.

[0028] Specifically, the disk saw blade 2 is a circular saw blade used to cut workpieces. The main function of the H-shaped steel 4 is to provide additional support and stability to ensure that the disk saw blade 2 does not generate excessive vibration and swing during the cutting process. The nozzles 3 are slidably connected along the outer periphery of the disk saw blade 2, and there can be multiple nozzles distributed around the disk saw blade. The function of these nozzles is to cool the disk saw blade 2, reduce the heat generated by friction during the cutting process, and thus extend the service life of the disk saw blade. The purpose of the pressure water inlet 5 is to provide a cooling water source to ensure that the cooling nozzles 3 can effectively cool the disk saw blade 2 during the cutting process.

[0029] Reference Figure 1 and Figure 3 The bottom of the H-shaped steel 4 is slidably connected with a conveying roller 1, the outer periphery of the disk saw blade 2 is slidably connected with an H-shaped steel 6, and a jet self-excited water chamber 8 is opened in the nozzle 3.

[0030] Specifically, the conveyor roller 1 supports and conveys the H-shaped steel 4 to ensure that it maintains a stable and accurate position during the cutting process. The H-shaped steel 6 provides additional support at the periphery of the disk saw blade 2 to ensure that the disk saw blade 2 remains stable during the cutting process and reduces vibration and deformation. The jet self-excited water chamber 8 is opened inside the nozzle 3 to further improve the cooling effect through the self-excited water flow, ensuring that the temperature of the disk saw blade 2 is kept within a controllable range during high-speed cutting.

[0031] Reference Figure 3 An annular air cavity 7 is provided in the nozzle 3 , and a pressure water outlet 9 is provided in the nozzle 3 .

[0032] Specifically, the annular air cavity 7 is designed to provide uniform cooling airflow around the entire disk saw blade to ensure that the entire cutting area is properly cooled and prevent local overheating. The pressure water outlet 9 allows the flow pressure of the cooling water to be adjusted.

[0033] Working principle: The nozzle 3 is self-excited to generate a pulse jet, which bombards the metal chips accumulated on the surface of the disc saw blade 2 through the water hammer principle to chip and remove them, thereby keeping the structure of the disc saw blade 2 stable.

[0034] The air flow velocity of the outer protective air layer is adjusted to be equivalent to the velocity of the pulsed water jet, which effectively reduces the kinetic energy loss caused by the high-speed friction between the jet and the external atmosphere and maintains the flushing ability of the jet.

[0035] The pulsed water jet bombards the surface of the disc saw blade 2 and disperses the metal deposits accumulated by cutting and mixes with the outer protective gas layer to produce atomized water. The small-particle atomized water quickly takes away the cutting heat, keeps the disc saw blade 2 at the designed working temperature, and ensures the efficient operation of the saw blade.

[0036] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
