Technical Field
[0001] This utility model relates to the field of chemical equipment technology, specifically to a tooling for manufacturing a gas distribution plate nozzle base. Background Technology
[0002] In various industrial sectors such as chemical, petrochemical, environmental protection, and energy, gas distribution plates are one of the core components of equipment such as gas-liquid reactors, absorption towers, and packed towers, and their performance directly affects the efficiency and effectiveness of the equipment. The nozzle base on the gas distribution plate, as a key component for uniform gas distribution, is crucial for ensuring the stable operation of the entire system due to its precision, durability, and ease of installation.
[0003] Currently, cold hydrogenation technology is the mainstream technology for polysilicon production. Cold hydrogenation technology involves reacting silicon tetrachloride, silicon powder, and hydrogen in a fluidized bed reactor to produce trichlorosilane.
[0004] The cold hydrogenation reactor is the core equipment of the cold hydrogenation unit, and the gas distributor of the reactor is an even more crucial internal component. The larger the diameter of the fluidized bed reactor, the higher the requirements for the uniformity and stability of gas distribution on the gas distribution plate. The manufacturing quality and precision of the gas distribution plate also determine the performance improvement.
[0005] Traditional nozzle base manufacturing often employs manual welding or simple machining, making it difficult to guarantee the positional accuracy and angular consistency of each nozzle. This can easily lead to low manufacturing precision of the gas distribution plate nozzle base, resulting in uneven gas distribution and affecting reaction efficiency. Manual operation is not only time-consuming and labor-intensive but also difficult to achieve large-scale production, failing to meet the demands of modern industry for high-efficiency production. The lack of standardized installation interfaces and positioning devices makes the installation process of the nozzle base on the gas distribution plate cumbersome, increasing installation costs and time. Therefore, this application proposes a tooling for manufacturing gas distribution plate nozzle bases to solve the aforementioned technical problems. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a tooling for manufacturing a gas distribution plate nozzle base, which has the advantages of high manufacturing precision, high production efficiency and convenient installation, and solves the problem of machining the inner hole after welding the nozzle base in traditional tooling.

[0009] The nozzle base includes a core rod and an adjusting nut. The core rod passes through the nozzle base and extends to the bottom of the nozzle base. The adjusting nut is movably connected to the bottom of the nozzle base and threaded to the outer surface of the core rod.
[0010] Furthermore, one end of the mandrel is a bolt head, the other end of the mandrel is a threaded rod, and the middle of the mandrel is a smooth rod end.
[0011] Furthermore, the nozzle base has a through hole inside, and the outer diameter of the optical rod end is smaller than the diameter of the through hole inside the nozzle base.
[0012] Furthermore, one end of the adjusting nut is a nut, and the other end of the adjusting nut is an adjusting rod.
[0013] Furthermore, there are two adjusting rods, and the ends of the adjusting rods are adapted to the bottom surface shape of the distributor head.
[0014] Furthermore, a ceramic fiber adhesive for heat insulation is provided between the protective sleeve and the cylinder body.
[0015] Furthermore, the distributor head has an opening inside that is compatible with the nozzle base.
[0016] Compared with the prior art, this utility model provides a tooling for manufacturing a gas distribution plate nozzle base, which has the following advantages:
[0017] 1. The tooling for manufacturing the nozzle base of this gas distribution plate, by inserting a mandrel and adjusting the height of the adjusting nut and rod, ensures that the center line of the nozzle base is parallel to the center of the distributor head.

The rigidity of the mandrel and the adjusting nut and rod limits welding deformation, which not only ensures the positioning accuracy of the nozzle base, but also avoids the problem of machining the inner hole of the nozzle base after welding, reducing production costs and achieving the advantages of high manufacturing precision and simple installation.
[0018] 2. The tooling for manufacturing the nozzle base of the gas distribution plate is made by producing different adjusting nuts according to the different center distances of the distributor end caps based on the diameter of the distributor end caps. This facilitates the simultaneous installation of multiple nozzle bases, thereby improving installation efficiency and effectively increasing the production efficiency of the gas distribution plate nozzle base.

[0024] 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.
[0025] Please see Figures 1 to 4 In this embodiment, a tooling for manufacturing a nozzle base for a gas distribution plate includes a support ring 4 fixedly installed inside the cylinder. The support ring 4 serves as a component support, bearing the weight of the entire distribution plate. A protective sleeve 2 is fixedly connected to the top of the support ring 4. The protective sleeve 2 is used to connect the distributor head 1 and the support ring 4, and also protects the ceramic fiber adhesive 3. The distributor head 1 is fixedly connected to the side of the protective sleeve 2 away from the cylinder. A nozzle base 5 is provided on the distributor head 1. A nozzle 6 is fixedly installed on the top of the nozzle base 5. The nozzle 6 is used for uniform gas distribution, generating eddies to ensure thorough gas mixing, reducing flow rate, and increasing reaction time.
[0026] In this embodiment, the nozzle base 5 includes a mandrel 51 and an adjusting nut 52. The mandrel 51 passes through the nozzle base 5 and extends to the bottom of the nozzle base 5. The adjusting nut 52 is movably connected to the bottom of the nozzle base 5 and threadedly connected to the outer surface of the mandrel 51. By inserting the mandrel 51 and adjusting the height of the adjusting nut 52, the centerline of the nozzle base 5 can be kept parallel to the center of the distributor head 1. The entire installation process is simple and efficient. The rigidity of the adjusting rod of the mandrel 51 and the adjusting nut 52 limits welding deformation, which not only ensures the positioning accuracy of the nozzle base 5, but also avoids the problem of machining the inner hole of the nozzle base 5 after welding, reducing production costs and achieving the advantages of high manufacturing precision and simple installation.
[0027] Specifically, one end of the mandrel 51 is a bolt head, the other end of the mandrel 51 is a threaded rod, and the middle of the mandrel 51 is a smooth rod end.
[0028] Specifically, the nozzle base 5 has a through hole inside, and the outer diameter of the rod end is smaller than the diameter of the through hole inside the nozzle base 5.
[0029] Specifically, one end of the adjusting nut 52 is a nut, and the other end of the adjusting nut 52 is an adjusting rod.
[0030] Specifically, there are two adjusting rods, and the ends of the adjusting rods are adapted to the bottom shape of the distributor head 1.
[0031] Specifically, the casing 2 is welded to the cylinder body; the casing 2 is welded to the top surface of the support ring 4; the distributor head 1 is welded to the casing 2; and the nozzle 6 is threaded onto the nozzle base 5.
[0032] In this embodiment, a ceramic fiber adhesive 3 for heat insulation is provided between the protective sleeve 2 and the cylinder body. The ceramic fiber adhesive 3 is used for heat insulation to prevent thermal stress from occurring in the cylinder body.
[0033] It should be noted that the distributor head 1 has an opening inside that matches the nozzle base 5. By manufacturing different adjusting nuts 52 according to the different center distances of the distribution holes in the distributor head 1, it is convenient to install multiple nozzle bases 5 at the same time, thereby improving installation efficiency and effectively increasing the production efficiency of the gas distribution plate nozzle base, achieving the advantage of high production efficiency.
[0034] The working principle of the above embodiments is as follows:
[0035] The nozzle base 5 is assembled onto the distributor head 1, through which a mandrel 51 is inserted, and an adjusting nut 52 is fitted. The angle is adjusted by the adjusting rod of the adjusting nut 52 so that the centerline of the nozzle base 5 is parallel to the center of the distributor head 1. The nozzle base 5 is spot-welded to fix it, the adjusting nut 52 is locked, and the nozzle base 5 is welded to the distributor head 1. The rigidity of the mandrel 51 and the adjusting rod of the adjusting nut 52 limits welding deformation. The fixture can be removed after the weld has cooled. Different adjusting rods for the adjusting nut 52 are made according to the different center distances of the orifice distribution of the distributor head 1, allowing multiple nozzle bases 5 to be installed simultaneously, thereby improving work efficiency.
