Technical Field

[0001] The invention relates to the technical field of a wear-resistant atomizing disk specially used for an atomizer, in particular to a wear-resistant atomizing disk structure capable of reducing an atomizing radius and a method for installing and disassembling the atomizing disk. Background Art

[0002] The nebulizer is used to atomize the test solution. It is an important component of the atomization system. Its performance has a significant impact on the precision of the measurement and chemical interference. Therefore, the nebulizer is required to have stable spray, small and uniform droplets and high atomization efficiency.

[0003] The atomizer disk of the atomizer in the prior art mostly limits the diameter of the atomizer wheel according to the diameter of the atomization reaction tower, the rotation speed of the atomizer and the size of the atomized particles. This places very precise requirements on the design rotation speed of the entire atomizer, and it is generally difficult to achieve it just right. In addition, the medium involved in the atomization contains a certain amount of impurities, which is itself a corrosive solution, which greatly shortens the service life of ordinary atomizer disks. Summary of the invention

[0004] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a wear-resistant atomizer disk structure and an installation and disassembly method for reducing the atomization radius, thereby effectively reducing the atomization radius, slowing down the wear inside the atomizer disk, and extending the service life of the atomizer disk.

[0006] A wear-resistant atomizing disk structure for reducing the atomization radius comprises a base of the atomizing disk, a large protrusion extending upward from the middle upper surface of the base, a small protrusion extending downward from the middle lower surface of the base, mounting holes are simultaneously provided in the middle of the large protrusion, the base and the small protrusion, and a power device for driving rotation is installed in the mounting hole; a wear-resistant lining is provided on the outside of the large protrusion, a nozzle ring is installed on the upper surface of the base by fixing bolts, a large circular hole is provided in the middle of the nozzle ring, the large protrusion is located at the center of the large circular hole, a plurality of small circular holes are spaced apart on the outer circumference of the nozzle ring, and a wear-resistant nozzle is installed in each small circular hole.

[0007] Its further technical solution is:

[0008] The wear-resistant nozzle is an integrated structure, and a bent spray channel is arranged inside the wear-resistant nozzle.

[0009] The structure of the wear-resistant nozzle is as follows: it comprises a first connecting part in a cylindrical structure, a second connecting part extending outwardly from one end of the first connecting part, an annular groove is arranged between the first connecting part and the second connecting part, a third connecting part extending outwardly from the outer end of the second connecting part with a smaller diameter than the second connecting part, and a third connecting part having a bottom opening The nozzle has a horizontal through hole formed in the middle of the third connecting part, the second connecting part and the first connecting part at the right end of the nozzle, and the through hole is a spray channel, which is connected to the nozzle.

[0010] The left end surface of the third connecting portion is a closed surface.

[0011] An O-ring is mounted on the annular groove, and a wear-resistant lining is mounted on the left end surface of the third connecting portion.

[0012] The structure of the nozzle ring is as follows: it includes a nozzle ring body, which is a thin-walled cylindrical structure with an open bottom. A large circular hole is opened in the middle of the top surface of the nozzle ring body, and twelve small circular holes are opened on the circumferential wall surface of the nozzle ring body. A lower edge extends from the bottom of the circumferential wall surface of the nozzle ring body, and a plurality of locking holes are opened on the lower edge.

[0013] The structure of the base is as follows: it comprises a base body, the base body is a thin disc structure, and a plurality of fastening holes are opened in the circumferential direction of the base body.

[0014] The wear-resistant nozzle is made of silicon carbide material.

[0015] The base is an integrated structure, and the mounting hole is a tapered hole.

[0016] A method for installing and disassembling a wear-resistant atomizing disk structure for reducing atomizing radius,

[0017] The installation steps are:

[0018] Step 1: Preparation: prepare the wear-resistant nozzle, nozzle ring, base, twelve fixing bolts, O-ring, asbestos gasket and wear-resistant lining;

[0019] Step 2: Put the wear-resistant lining on the large protrusion of the base;

[0020] Step 3: Install each wear-resistant nozzle into the small round hole of the nozzle ring, put the O-ring and asbestos gasket on the nozzle ring, and after installation, the first connecting part of the wear-resistant nozzle protrudes from the inner wall of the nozzle ring;

[0021] Step 4: Install the nozzle ring with the wear-resistant nozzle on the base as a whole and lock it with fixing bolts;

[0022] The disassembly steps are:

[0023] Step 1: Loosen each fixing bolt.

[0024] Step 2: Separate the base and the nozzle ring equipped with the wear-resistant nozzle;

[0025] Step 3: Remove each wear-resistant nozzle from the nozzle ring.

[0026] The beneficial effects of the present invention are as follows:

[0027] The invention has a compact and reasonable structure and is easy to operate. By adopting a wear-resistant lining with a special shape and adding a uniquely designed wear-resistant nozzle at the material outlet of the atomizing disk (i.e., the nozzle), the wear inside the atomizing disk is slowed down, and the atomization radius of the atomizing disk can be reduced, thereby slowing down the wear inside the atomizing disk and extending the service life of the atomizing disk.

[0028] The existing atomizing disk nozzles are mostly made of metal drilled straight holes, and the atomizing radius of the atomizing disk has not changed. It is very likely that the medium is not fully atomized and is directly thrown onto the wall of the reflecting tower due to the excessively large radius. Secondly, the service life is shortened due to the lack of a wear-resistant lining. The wear-resistant nozzle of the present invention not only meets the service life but also changes the atomizing radius, both from the unique appearance design and the change of the material used in silicon carbide.

[0048] The specific implementation of the present invention is described below in conjunction with the accompanying drawings.

[0051] The structure of the wear-resistant nozzle 1 is as follows: it includes a first connecting portion 103 in a cylindrical structure, a second connecting portion 105 extending outward from one end of the first connecting portion 103, an annular groove 104 is provided between the first connecting portion 103 and the second connecting portion 105, a third connecting portion 106 with a smaller diameter than the second connecting portion 105 extending outward from the outer end of the second connecting portion 105, and a bottom of the third connecting portion 106 is provided with a The nozzle 101 has a horizontal through hole formed in the middle of the third connecting part 106, the second connecting part 105 and the first connecting part 103 at the right end of the nozzle 101. The through hole is a spray channel 102, and the spray channel 102 is connected to the nozzle 101.

[0052] The left end surface of the third connecting portion 106 is a closed surface.

[0053] An O-ring 5 is mounted on the annular groove 104 , and a wear-resistant lining plate 7 is mounted on the left end surface of the third connecting portion 106 .

[0054] The structure of the nozzle ring 2 is as follows: it includes a nozzle ring body 201, which is a thin-walled cylindrical structure with an open bottom.

After the base 3 and the nozzle ring 2 are matched, there is a gap between the outer edge of the nozzle ring 2 and the step surface 701. The gap is left to control thermal expansion and contraction to ensure reliability in use.

[0059] The installation and disassembly method of the wear-resistant atomizing disk structure for reducing the atomizing radius in this embodiment is as follows:

[0065] The disassembly steps are:

[0066] Step 1: Loosen each fixing bolt 4.

[0067] Step 2: Separate the base 3 and the nozzle ring 2 equipped with the wear-resistant nozzle 1;

[0068] Step 3: Remove each wear-resistant nozzle 1 on the nozzle ring 2.

[0069] Easy to install and disassemble, easy to replace the wear-resistant nozzle, and high working efficiency.

[0070] The specific structure and functions of the present invention are as follows:

[0071] A wear-resistant lining plate 7 is designed on the base 3;

[0072] Twelve wear-resistant special-shaped wear-resistant nozzles 1 are designed on the circumference of the nozzle ring 2, and extend inward to make them immune during normal operation (that is, a protective layer is formed on the inner circle to resist the wear of the substrate by the material), thereby achieving the purpose of slowing down the wear of the inner wall substrate of the atomizer disk; a shock-absorbing sealing ring and an asbestos pad are also interspersed in the middle of the atomizer disk, and twelve fixing bolts 4 are used to fasten the base 3 and the nozzle ring 2, reducing the difficulty of overall processing, and the central inner hole is designed as a tapered hole, which makes frequent installation convenient and accurate.

[0073] The working principle of the present invention is:

[0074] The present invention uniquely designs twelve wear-resistant nozzles 1 with special structures on the basis of directly punching holes on the original atomizing disk nozzle ring 2, and adds a wear-resistant lining plate 7 with a special surface on the base 3, thereby achieving the effect of changing the atomizing radius of the atomizing disk and overcoming the difficulty of extremely fast wear of the original disk cavity.

[0075] The working process of the present invention is:

[0076] The atomized medium is evenly distributed to the atomizing disk through a material distributor (not shown in the figure). Due to the high-speed rotation of the atomizing disk, a huge centrifugal force is generated. Under the action of the centrifugal force, the atomized medium smoothly passes through the wear-resistant lining 7 and is sprayed out by twelve wear-resistant nozzles 1. The unique design of the wear-resistant nozzles 1 opening an outlet from the bottom achieves the atomization effect of changing the atomization radius.

[0077] The structure in the prior art uses an atomizing disk of equal diameter, and its atomizing radius is assumed to be able to reach 9 meters. After adopting the atomizing disk described in the present invention, the atomizing radius is only 8.5 meters, and the material will not be directly sprayed onto the inner wall of the reaction tower, reducing the risk of material sticking to the inner wall of the reaction tower and water accumulation at the bottom, ensuring the normal and orderly progress of the subsequent processes; and extending the service life of the overall equipment.

[0078] The existing method of directly punching holes at the nozzle of the atomizing disk and the structure without a wear-resistant lining 7 in the inner cavity can no longer meet the needs of harsh working conditions on site. The present invention has a unique design by adding a nozzle of special shape and special material to the disk body, extending it inward to produce its own immune protection to slow down the wear of the inner wall base part and adding a special-shaped wear-resistant lining 7 in the inner cavity, thus perfectly realizing the atomizing disk that changes the atomization radius and is durable; the central mounting hole 301 of the atomizing disk is made into a tapered hole, which makes frequent installation accurate and convenient.

[0079] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
