Description

Technical Field

[0001] This utility model belongs to the field of vacuum melting technology, specifically a continuous feeding device for a vacuum melting atomizing furnace. Background Technology

[0002] Vacuum melting and atomizing furnaces are advanced equipment mainly used to produce ideal powders, such as nickel powder and 304 powder, through rapid solidification processes. If the water-cooled copper crucible is replaced, titanium powder can also be prepared. Hydrogen storage materials are materials that can store hydrogen gas, and their preparation process usually requires melting, atomization and other steps. As an advanced metal powder preparation equipment, vacuum melting and atomizing furnaces play an important role in the preparation of hydrogen storage materials.

[0003] Currently, the feeding method for vacuum melting furnaces is generally to add all the raw materials to be melted into the system at once, and then add no more materials during the entire melting process, thus ensuring that the vacuum degree of the system is not affected. However, after each raw material melting is completed, the vacuum degree of the entire system must be broken and new raw materials must be added. Therefore, melting furnaces using this feeding mechanism cannot achieve continuous production and have relatively low production efficiency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a continuous feeding device for a vacuum melting atomizing furnace, which effectively solves the problem of low production efficiency caused by the inability of current melting furnaces to achieve continuous production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a continuous feeding device for a vacuum melting atomizing furnace, comprising a furnace body, wherein a feeding mechanism is provided at the top of the furnace body;

[0006] The feeding mechanism includes a feeding hopper fixed to the top of the furnace body, a vertical cylinder fixedly connected to the top of the feeding hopper, a feeding pipe fixedly connected to the top of the vertical cylinder, a sealing cap at the top of the feeding pipe, a conveying cylinder connected to the feeding pipe fixedly connected to the inner top wall of the vertical cylinder, a conveying pipe fixedly connected to the bottom of the conveying cylinder, a base plate inside the feeding hopper, the bottom end of the conveying pipe located at the top of the base plate, two arc-shaped through grooves symmetrically arranged on the base plate, the width of the arc-shaped through grooves being greater than the outer diameter of the conveying pipe.

[0007] Preferably, a support plate is fixedly installed on the outside of the conveying pipe, and a support shaft is rotatably connected to the bottom of the support plate, with the bottom end of the support shaft fixed to the top of the chassis.

[0010] Preferably, a sleeve plate is fixedly installed inside the vertical cylinder. The sleeve plate is fixedly sleeved on the outside of the conveying pipe. Two arc-shaped vertical plates are symmetrically fixedly connected to the sleeve plate.

[0011] Preferably, the bottom of the arc-shaped upright plate is fixedly connected with multiple limiting rods at equal angles, and the bottom end of each limiting rod is provided with a limiting ball located at the top of the chassis.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1 The present invention relates to a continuous feeding device for a vacuum melting atomizing furnace, comprising a furnace body 1, wherein a feeding mechanism 2 is provided on the top of the furnace body 1.

[0025] Specifically, by Figure 2-4The feeding mechanism 2 includes a feeding hopper 201 fixed to the top of the furnace body 1. A vertical cylinder 202 is fixedly connected to the top of the feeding hopper 201. A feeding pipe 207 is fixedly connected to the top of the vertical cylinder 202. A sealing cap 206 is provided at the top of the feeding pipe 207. A conveying cylinder 208 communicating with the feeding pipe 207 is fixedly connected to the inner top wall of the vertical cylinder 202. A conveying pipe 2017 is fixedly connected to the bottom of the conveying cylinder 208. A base 209 is provided inside the feeding hopper 201. The bottom end of the conveying pipe 2017 is located at the top of the base 209. Two arc-shaped through grooves 2016 are symmetrically provided on the base 209. The width of the arc-shaped through grooves 2016 is greater than the outer diameter of the conveying pipe 2017. A support plate 2012 is fixedly installed on the outer side of the conveying pipe 2017. A support shaft 2013 is rotatably connected to the bottom of the 12. The bottom end of the support shaft 2013 is fixed to the top of the chassis 209. An L-shaped seat 204 is fixedly connected to the top of the vertical cylinder 202. A drive motor 205 is fixedly installed on the L-shaped seat 204. A drive shaft 203 is fixedly connected to the drive motor 205. The bottom end of the drive shaft 203 extends into the interior of the vertical cylinder 202 and is located above the chassis 209. A sealed bearing is provided at the top of the vertical cylinder 202. The sealed bearing is sleeved on the outside of the drive shaft 203. The drive shaft 203 is located on the outside of the conveying cylinder 208. A drive gear 2011 is fixedly installed on the outside of the drive shaft 203. A driven gear 2010 is fixedly installed on the outside of the support shaft 2013. The driven gear 2010 meshes with the drive gear 2011.

[0026] In operation, the raw material is first fed into the conveying cylinder 208 through the feed pipe 207, and then enters the conveying pipe 2017. The drive motor 205 is then started, which drives the drive shaft 203 to rotate and drives the drive gear 2011 to rotate. Since the drive gear 2011 is meshed with the driven gear 2010, it drives the support shaft 2013 to rotate. At the same time, the chassis 209 rotates. When the arc-shaped channel 2016 moves to the bottom of the conveying pipe 2017, the raw material in the conveying pipe 2017 falls into the furnace body 1 through the arc-shaped channel 2016. The intermittent movement of the arc-shaped channel 2016 to the bottom of the conveying pipe 2017 realizes the continuous feeding of raw materials, thus improving production efficiency.

[0027] Specifically, by Figure 4-5 As shown, a sleeve plate 2014 is fixedly installed inside the vertical cylinder 202. The sleeve plate 2014 is fixedly sleeved on the outside of the material conveying pipe 2017. Two arc-shaped vertical plates 2015 are symmetrically fixedly connected to the sleeve plate 2014. A reinforcing rod 2020 is fixedly connected between the side of the two arc-shaped vertical plates 2015 that is far away from each other and the bottom of the sleeve plate 2014. Multiple limiting rods 2018 are fixedly connected at equal angles to the bottom of the arc-shaped vertical plates 2015. Each limiting rod 2018 has a limiting ball 2019 located at the top of the chassis 209 at its bottom end.

[0028] In use, two arc-shaped upright plates 2015 are symmetrically arranged on the sleeve plate 2014, and multiple limiting rods 2018 are evenly arranged at the bottom of the two arc-shaped upright plates 2015. Then, limiting balls 2019 located at the top of the chassis 209 are set at the bottom of each limiting rod 2018 to limit the chassis 209, and finally ensure that the chassis 209 rotates smoothly to avoid shaking.
