[0001] This utility model relates to the field of vertical vacuum furnace technology, specifically to a vertical vacuum furnace that facilitates unloading. Background Technology
[0002] A vertical vacuum furnace is a device that performs high-temperature processing in a vacuum environment. It is widely used in many industries such as metal processing, semiconductors, glass, automobile manufacturing, chemicals, electronics, and powder metallurgy.
[0003] In existing technology, vertical vacuum furnaces mainly consist of a furnace body, a furnace cover, a vacuum system, and a heating system. The vacuum system provides a vacuum environment inside the furnace body, the heating system heats the raw materials inside the furnace, and a discharge port is located at the bottom of the furnace body. The furnace cover is used to seal the discharge port.
[0004] However, after the raw materials are heated in the furnace, the furnace cover supports the raw materials at the discharge port. When the staff rotates the furnace cover to open the discharge port of the furnace, the raw materials will create resistance to the furnace cover, which makes it time-consuming and laborious for the staff to open the furnace cover, thus making it inconvenient for the vertical vacuum furnace to unload materials. Utility Model Content
[0005] The purpose of this utility model is to provide a vertical vacuum furnace that facilitates material unloading, in order to solve the technical problem in the prior art where, after the raw material is heated in the furnace body, the furnace cover bears the raw material at the outlet. When the operator rotates the furnace cover to open the outlet of the furnace body, the raw material will create resistance to the furnace cover, which makes it time-consuming and laborious for the operator to open the furnace cover, thus making it inconvenient for unloading materials from the vertical vacuum furnace.
[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:
[0007] A vertical vacuum furnace for easy unloading includes:
[0008] The furnace body has a feeding hopper fixedly connected to its bottom end, a sealing column rotatably connected to the inner wall of the feeding hopper, and a door valve fixedly connected to the bottom end of the sealing column.
[0009] The partition has two sets and is installed inside the furnace body. The side end of the partition is hinged to a hinge seat, which is fixedly connected to the inner wall of the furnace body.
[0010] The drive assembly has two sets, each hinged to a partition plate, and is fixedly connected to the inner wall of the furnace.
[0011] As a further embodiment of this utility model: staggered grooves are provided at the opposite ends of the two sets of partitions, and the two sets of partitions are staggered.
[0012] As a further embodiment of this utility model: the bottom end of the partition plate is fixedly connected with an interlaced groove for sealing the gasket.
[0013] As a further embodiment of this utility model: a support frame is fixedly connected to the outer wall of the bottom of the furnace body, and the height of the support frame is higher than the height of the feeding hopper.
[0014] As a further embodiment of this utility model: two sets of air inlets are provided on the side of the furnace body, and the two sets of air inlets are respectively located at the upper and lower ends of the partition plate. Two diversion pipes are fixedly connected to the side of the furnace body, and the diversion pipes are interconnected with the air inlets.
[0015] As a further embodiment of this utility model: a conveying pipe is fixedly connected to the side end of the diversion pipe, and the two sets of diversion pipes are respectively connected to the conveying pipe.
[0016] As a further embodiment of this utility model: the outer wall of the valve is fixedly connected with a number of teeth along the axis, and the side end of the valve is connected to a drive gear shaft, which is located at the bottom of the hopper.
[0017] As a further embodiment of this utility model: a rotating shaft is fixedly connected to the top of the drive gear shaft, a servo motor is fixedly connected to the top of the rotating shaft, and the top of the servo motor is fixedly connected to the hopper.
[0018] As a further embodiment of this utility model: the driving assembly includes a hydraulic actuator and a hydraulic rod, with connecting plates rotatably connected to both ends of the hydraulic actuator, the top end of the hydraulic actuator being fixedly connected to the hydraulic rod, the connecting plates being fixedly connected to the inner wall of the furnace, and the top end of the hydraulic rod being hinged to a partition plate.
[0019] As a further embodiment of this utility model: the hydraulic rod is rotatably connected to side plates at both ends, the hydraulic rod has a positioning hole through it, a positioning post is rotatably connected to the inner wall of the positioning hole, the two ends of the positioning post are fixedly connected to the side plates, and the top of the side plates is fixedly connected to the partition plate.
[0020] The beneficial effects of this utility model are:
[0021] 1. When the raw material is poured into the furnace for heating, the two sets of baffles are parallel to the top of the furnace and provide support for the raw material. The baffles isolate the raw material from the sealing column. When the raw material is unloaded, it will not accumulate on the top of the sealing column, thus avoiding the phenomenon that the raw material provides resistance to the sealing column. When the operator rotates the valve, the valve drives the sealing column to rotate, which makes it easy to remove the sealing column from the hopper.
[0022] 2. When the sealing column is removed from the hopper, the drive assembly rotates the partition downwards. The side of the partition rotates along the hinge seat, thereby releasing the partition from its function of providing support for the raw material. The raw material slides down the surface of the partition and then falls into the hopper, where it is discharged from the bottom. The drive assembly achieves the effect of automatically controlling the rotation of the partition. Attached Figure Description

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0032] like Figures 1-6 As shown, a vertical vacuum furnace for easy unloading includes: a furnace body 1, a partition 15, and a drive assembly.
[0033] A feeding hopper 5 is fixedly connected to the bottom of the furnace body 1. A sealing column 11 is rotatably connected to the inner wall of the feeding hopper 5. A valve 6 is fixedly connected to the bottom of the sealing column 11. Two sets of partitions 15 are provided and are located inside the furnace body 1. A hinge seat 14 is hinged to the side of the partition 15 and is fixedly connected to the inner wall of the furnace body 1. Two sets of drive components are provided and are respectively hinged to the partitions 15. The drive components are fixedly connected to the inner wall of the furnace body 1. When the raw material is poured into the furnace body 1 for heating, the two sets of partitions 15 are parallel to the top of the furnace body 1. The two sets of partitions 15 provide support for the raw material. The partitions 15 isolate the raw material from the sealing column 11. When the raw material is unloaded, the raw material will not accumulate on the top of the sealing column 11, thereby avoiding the phenomenon that the raw material provides resistance to the sealing column 11. When the operator rotates the valve 6, the valve 6 drives the sealing column 11 to rotate, thereby facilitating the removal of the sealing column 11 from the feeding hopper 5.
[0034] When the sealing column 11 is removed from the hopper 5, the drive assembly rotates the partition 15 downwards. The side end of the partition 15 rotates along the hinge seat 14, thereby releasing the partition 15 from its function of providing support for the raw material. The raw material slides down the surface of the partition 15 and then falls into the hopper 5, where it is discharged from the bottom. The drive assembly achieves the effect of automatically controlling the rotation of the partition 15.
[0035] In some specific implementations, staggered grooves 19 are provided at opposite ends of the two sets of partitions 15, and the two sets of partitions 15 are staggered. The bottom end of each partition 15 is fixedly connected to the staggered grooves 19 for sealing the gasket 20. When the two sets of partitions 15 are in contact, the staggered grooves 19 provided in the partitions 15 can ensure that the two sets of partitions 15 are staggered and abut against each other, thereby preventing the raw material from flowing out from the gap between the two sets of partitions 15. The gasket 20 further seals the gap between the staggered grooves 19.
[0036] In some specific implementations, a support frame 2 is fixedly connected to the bottom outer wall of the furnace body 1. The height of the support frame 2 is higher than the height of the feeding hopper 5. The support frame 2 provides support for the furnace body 1 and prevents the feeding hopper 5 from contacting the ground.
[0037] In some specific implementations, two sets of air inlets 10 are provided on the side of the furnace body 1. The two sets of air inlets 10 are located at the upper and lower ends of the partition plate 15, respectively. Two diversion pipes 3 are fixedly connected to the side of the furnace body 1. The diversion pipes 3 are interconnected with the air inlets 10. A conveying pipe 4 is fixedly connected to the side of the diversion pipe 3. The two sets of diversion pipes 3 are interconnected with the conveying pipe 4. When the furnace body 1 provides a vacuum environment for heating raw materials, in order to avoid the vacuum in the furnace body 1 causing the valve 6 to be resisted by external air pressure, before the sealing column 11 is removed from the feed hopper 5, filtered air is introduced into the conveying pipe 4. The conveying pipe 4 then diverts the air through the diversion pipes 3 and then passes through the air inlets 10 into the furnace body 1, thereby ensuring that the air pressure in the furnace body 1 is the same as the external air pressure, thus avoiding the valve 6 being affected by the resistance of external air pressure.
[0038] In some specific implementations, the outer wall of the valve 6 is fixedly connected with several teeth along its axis. The valve 6 is connected to a drive gear shaft 7 by meshing teeth on its side. The drive gear shaft 7 is located at the bottom of the hopper 5. The top of the drive gear shaft 7 is fixedly connected to a rotating shaft 8. The top of the rotating shaft 8 is fixedly connected to a servo motor 9. The top of the servo motor 9 is fixedly connected to the hopper 5. To further facilitate the removal of the sealing column 11 from the hopper 5, the servo motor 9 is activated. The servo motor 9 drives the rotating shaft 8 to rotate, which in turn drives the drive gear shaft 7 to rotate. The drive gear shaft 7 drives the valve 6 to rotate through meshing teeth. The valve 6 then drives the sealing column 11 to rotate, thereby achieving the effect of automatically removing the sealing column 11 from the hopper 5. This avoids the time-consuming and laborious process of manually removing the valve 6. When the sealing column 11 is installed on the hopper 5, the teeth on the valve 6 are aligned with the drive gear shaft 7, and the servo motor 9 is activated.
[0039] In some specific embodiments, the drive assembly includes: a hydraulic actuator 12 and a hydraulic rod 13. Connecting plates 21 are rotatably connected to both ends of the hydraulic actuator 12. The top end of the hydraulic actuator 12 is fixedly connected to the hydraulic rod 13. The connecting plates 21 are fixedly connected to the inner wall of the furnace body 1. The top end of the hydraulic rod 13 is hinged to a partition plate 15. Side plates 16 are rotatably connected to both ends of the hydraulic rod 13. A positioning hole 18 is formed through the hydraulic rod 13. A positioning post 17 is rotatably connected to the inner wall of the positioning hole 18. Both ends of the positioning post 17 are fixedly connected to the side plate 16. The top of plate 16 is fixedly connected to partition 15. When the drive assembly flips partition 15 downward, hydraulic device 12 operates and pulls hydraulic rod 13. Hydraulic rod 13 abuts against positioning post 17 through positioning hole 18 and pulls positioning post 17. Positioning post 17 pulls side plate 16, and side plate 16 pulls partition 15. When partition 15 starts to rotate along hinge seat 14, positioning post 17 rotates along the inner wall of positioning hole 18. At the same time, the side end of hydraulic device 12 rotates along connecting plate 21, thereby realizing the effect of drive assembly automatically pulling partition 15 downward.

All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
