Description

Technical Field

[0001] This utility model relates to the field of inert atmosphere protection technology, specifically to a feeding device for inert atmosphere protection. Background Technology

[0002] Inert atmosphere protected feeding devices are mainly used to prevent materials from reacting with oxygen, water vapor and other components in the air during material conveying and processing. For some materials that are easily oxidized, inert atmosphere protection can effectively isolate oxygen and prevent oxidation reactions during the feeding process, thereby ensuring the purity and performance of the materials.

[0003] An inert gas protected heating atmosphere furnace, authorized by announcement number CN216644937U, includes a mounting box, comprising a housing for mounting and fixing the atmosphere furnace; a heating mechanism, mounted on the mounting box, including a heating component mounted on the mounting box and a cooling component below the heating component, the heating component being used to heat the atmosphere furnace, and the cooling component being used to control the temperature inside the atmosphere furnace; and a fixing mechanism, located below the heating mechanism, for fixing the heating mechanism. This atmosphere furnace first introduces inert gas into the heating component to prevent excessive temperature from damaging the atmosphere furnace. The atmosphere furnace is heated by the heating component, and the temperature is controlled by the cooling component. The furnace temperature can be promptly reduced after heating to prevent burns to operators and ensure the quality of the atmosphere furnace. However, this inert gas protective feeding device lacks a backflow control mechanism after inert gas delivery, making the purity of the inert gas in the feeding tank easily contaminated. Furthermore, the inert gas feeding structure needs improvement to avoid uneven atmosphere distribution or poor gas flow due to material accumulation.

[0004] To address the aforementioned problems, an inert atmosphere-protected feeding device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an inert atmosphere protection feeding device, which solves the problem that in the existing inert atmosphere protection feeding devices in the background art, the lack of a reflux mechanism after the inert gas is transported makes the purity of the inert gas in the feeding tank easily contaminated. In addition, the inert atmosphere feeding structure needs to be improved to avoid the problem of uneven atmosphere or poor gas flow caused by material accumulation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inert atmosphere protected feeding device, comprising an inert atmosphere storage tank, wherein the output end of the inert atmosphere storage tank is provided with a flow guiding and conveying mechanism for controlling the output of the atmosphere, and one side of the flow guiding and conveying mechanism is provided with a self-locking mechanism for preventing backflow, the inert atmosphere storage tank includes a control component, the flow guiding and conveying mechanism is connected to the output end of the control component, the flow guiding and conveying mechanism includes an air pump motor, the output end of the air pump motor is provided with an air supply fan, the self-locking mechanism further includes a side conical conveying component sleeved on one side of the air supply fan, the upper end of the side conical conveying component is connected to a ventilation component, and a gravity suspension component is movably sleeved inside the side conical conveying component.

[0007] Preferably, the inert atmosphere storage tank further includes a tank body fixedly disposed at the lower end of the control component, and a tank cover is disposed at the upper end of the control component.

[0008] Preferably, the control component further includes an air inlet pipe fixedly installed on one side, a pressure gauge fixedly installed on one side of the air inlet pipe, and an air delivery pipe fixedly installed on the opposite side of the air inlet pipe, the air delivery pipe being connected to one side of an air delivery fan.

[0009] Preferably, the side of the tank is set as an inclined side.

[0010] Preferably, the lower end of the side conical conveyor is connected to one side as a lower channel, the upper end of the side conical conveyor is connected to one side as an upper channel, and the gravity suspension component is disposed between the lower channel and the upper channel.

[0011] Preferably, the ventilation assembly includes a cover frame screwed to the upper end of the side conical conveyor, a dust cover is provided on one side of the center of the cover frame, and an air hole is provided between the cover frame and the dust cover.

[0012] Preferably, the gravity suspension assembly further includes a sliding and lifting insert disposed inside the side conical conveyor.

[0013] Preferably, the lower end of the plug is connected to a limiting cone plate, and a cross-shaped vent is fixedly provided at the lower end of the limiting cone plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model provides an inert atmosphere protection feeding device. Through the combination of a self-locking mechanism and a flow guiding and conveying mechanism, the air supply fan rotates under the drive of the air pump motor, driving the inert atmosphere to the side of the self-locking mechanism. At the same time, one side of the air supply fan and the side conical conveyor is set as a cone, which compresses it during the inert atmosphere conveying, providing sufficient lifting force for the gravity suspension component. When the lifting force is greater than the gravity suspension component's own weight, the gravity suspension component moves upward, making the interior of the side conical conveyor connected to complete the inert atmosphere conveying. When the air pump motor stops rotating, the gravity suspension component falls due to its own weight, realizing channel blockage and preventing backflow. This solves the problem in existing inert atmosphere protection feeding devices where the lack of a backflow control mechanism after inert gas conveying makes the purity of the inert gas in the feeding tank easily contaminated.

[0016] 2. The present invention provides an inert atmosphere protection feeding device, which achieves stable inert atmosphere delivery by setting an inert atmosphere storage tank in the feeding path and using the inert atmosphere storage tank as the storage medium. The guiding and conveying mechanism is driven at the output end of the inert atmosphere storage tank to ensure the stability of inert atmosphere transmission. This solves the problem that the structure of the existing inert atmosphere protection feeding device needs to be improved, and avoids the problem of uneven atmosphere or poor gas flow caused by material accumulation.

Detailed Implementation

[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] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0026] Combination Figure 1 The present invention discloses an inert atmosphere protection feeding device, comprising an inert atmosphere storage tank 1, an inert atmosphere storage tank 1 having a flow guiding and conveying mechanism 2 for controlling atmosphere output at its output end, a self-locking mechanism 3 for preventing backflow on one side of the flow guiding and conveying mechanism 2, an inert atmosphere storage tank 1 having a control component 12, the flow guiding and conveying mechanism 2 being connected to the output end of the control component 12, the flow guiding and conveying mechanism 2 having an air pump motor 21, an air supply fan 22 being provided at the output end of the air pump motor 21, and the self-locking mechanism 3 having a side conical conveying component 31 sleeved on one side of the air supply fan 22, an air venting component 32 being connected to the upper end of the side conical conveying component 31, and a gravity suspension component 33 being movably sleeved inside the side conical conveying component 31.

[0027] Specifically, the control component 12 delivers inert atmosphere to one side of the air supply fan 22. The air supply fan 22 rotates under the drive of the air pump motor 21, driving the inert atmosphere to one side of the self-locking mechanism 3. At the same time, one side of the air supply fan 22 and the side conical conveyor 31 is set as conical, which squeezes it while the inert atmosphere is being delivered, providing sufficient lifting force for the gravity suspension component 33. When the lifting force is greater than the weight of the gravity suspension component 33 itself, the gravity suspension component 33 moves upward, so that the interior of the side conical conveyor 31 is connected to complete the delivery of inert atmosphere. When the air pump motor 21 stops rotating, the gravity suspension component 33 is lowered by its own weight, realizing the channel blockage and preventing backflow. In this structure, the inert atmosphere feeding device uses the inert atmosphere storage tank 1 as the storage medium to achieve stable delivery of inert atmosphere. The guide conveying mechanism 2 is driven at the output end of the inert atmosphere storage tank 1 to ensure the stability of inert atmosphere transmission.

[0028] The present invention will be further described below with reference to the embodiments.

[0029] Example 1:

[0030] Combination Figures 2-4 The inert atmosphere storage tank 1 also includes a tank body 11 fixedly disposed at the lower end of the control component 12, and a tank cover 13 disposed at the upper end of the control component 12. The tank body 11 is used to store inert atmosphere, and the tank cover 13 can be removed for easy maintenance of the tank body 11 and the control component 12.

[0031] The control assembly 12 also includes an air inlet pipe 121 fixedly installed on one side. A pressure gauge 122 is fixedly installed on one side of the air inlet pipe 121, and an air delivery pipe 123 is fixedly installed on the opposite side of the air inlet pipe 121. The air delivery pipe 123 is connected to one side of the air delivery fan 22. The air inlet pipe 121 is switchable. The pressure gauge 122 is used to monitor the pressure of the inert atmosphere in the control assembly 12 and the tank 11. The air delivery pipe 123 is used to deliver the inert atmosphere to the guide flow conveying mechanism 2.

[0032] The side of the tank 11 is set as a bevel 221, which fits against the inner wall of the side conical conveyor 31 to achieve pressurized conveying of inert atmosphere.

[0033] Example 2:

[0034] Combination Figure 5 and Figure 6The lower end of the side conical conveyor 31 is connected to the lower channel 311, and the upper end of the side conical conveyor 31 is connected to the upper channel 312. The gravity suspension component 33 is disposed between the lower channel 311 and the upper channel 312. By controlling the raising and lowering of the gravity suspension component 33, the connection between the lower channel 311 and the upper channel 312 can be controlled. When the gravity suspension component 33 rises, the lower channel 311 and the upper channel 312 are connected to each other. When the gravity suspension component 33 descends, the lower channel 311 and the upper channel 312 are separated.

[0035] The ventilation component 32 includes a cover frame 321 screwed to the upper end of the side conical conveyor 31. A dust cover 323 is provided on one side of the center of the cover frame 321. An air hole 322 is provided between the cover frame 321 and the dust cover 323. The cover frame 321 and the dust cover 323 are connected to close the upper end of the side conical conveyor 31. The opening of the air hole 322 facilitates the outward compression of air when the gravity suspension component 33 moves upward.

[0036] The gravity suspension component 33 also includes a plug 331 that is slidably and vertically disposed inside the side conical conveyor 31. The plug 331 is slidably disposed in the channel at the upper end of the side conical conveyor 31. No matter how the plug 331 is raised or lowered, the upper channel 312 and the air hole 322 are not connected to each other.

[0037] The lower end of the plug 331 is connected to a limiting cone plate 332. A cross-shaped vent 333 is fixedly installed at the lower end of the limiting cone plate 332. The limiting cone plate 332 is used to block the connection between the lower channel 311 and the upper channel 312. The cross-shaped arrangement of the cross-shaped vent 333 restricts the vertical lifting of the gravity suspension component 33 while allowing the lower channel 311 and the upper channel 312 to connect when the gravity suspension component 33 moves upward.
