Description

Technical Field

[0001] This utility model relates to the technical field of cylinder vacuuming devices, specifically an automatic vacuuming device for high-pressure cylinders. Background Technology

[0002] A gas cylinder is a steel cylinder used to store high-pressure oxygen, coal gas, liquefied petroleum gas, etc. It can increase the safety performance of gas storage. Gas cylinders are closely related to human life. However, before using a gas cylinder, the air inside it needs to be completely removed. Usually, a special gas cylinder vacuum device is used to operate this. However, some problems still occur in the actual use of existing gas cylinder vacuum devices.

[0003] For example, patent application number CN202022949925.4 discloses a gas cylinder vacuuming device, including a vacuum chamber, a vacuum pump, and a sealing gasket. The vacuum pump is bolted to one side of the upper end of the vacuum chamber, and a gas pipe is connected to one side of the vacuum pump via a pipe. The gas pipe is connected to the vacuum chamber via a pipe clamp. A door is connected to the outer side of the vacuum chamber via a hinge. An instrument panel is connected to the door via a slot. An operation panel is provided below the instrument panel. The operation panel is connected to the vacuum chamber via a slot. This device has the characteristic of improving the vacuuming quality of gas cylinders. Existing gas cylinder vacuuming devices generally have single functions and are often inconvenient to operate multiple gas cylinders during use, which leads to a decrease in vacuuming efficiency and affects the working efficiency of the device.

[0004] To address the aforementioned problems, an automatic vacuuming device for high-pressure steel cylinders is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic vacuuming device for high-pressure steel cylinders. By using this device, the problem of existing steel cylinder vacuuming devices generally having limited functions and being inconvenient to operate multiple steel cylinders during use, which leads to reduced vacuuming efficiency and affects the working efficiency of the device, is solved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic vacuuming device for high-pressure steel cylinders, comprising a device body and a sealed chamber fixedly connected to one side of the device body. A controller is also fixedly connected to one side of the device body. The device body is provided with a placement mechanism, which serves to place multiple sets of high-pressure steel cylinders. The placement mechanism includes a motor fixedly connected inside the device body. A heat dissipation groove for cooling the motor is opened on one side of the device body. A vacuum pump is fixedly connected to one side of the controller. Multiple vacuum pumps are provided. A telescopic cylinder is fixedly connected to the top of the device body.

[0007] Preferably, the output end of the motor is fixedly connected to a screw, the screw is threadedly connected to a sliding table, and the sliding table is slidably connected inside the sealed chamber.

[0008] The above-mentioned structure design uses a motor to drive the screw to rotate, and the threaded transmission drives the sliding table to slide smoothly in the sealed chamber, realizing the automatic switching between the placement and vacuuming positions of the gas cylinder. This reduces manual handling operations, improves the automation level of the device, and the sliding connection method ensures the stability of the sliding table movement, preventing the gas cylinder from tipping over during movement.

[0009] Preferably, the top of the sliding table is provided with a placement slot, and multiple sets of placement slots are provided. The output end of the telescopic cylinder is fixedly connected to a connecting frame, and the bottom of the connecting frame is fixedly connected to a sliding box.

[0010] With the above-mentioned structural design, multiple placement slots can hold multiple steel cylinders simultaneously. In conjunction with the telescopic cylinder driving the connecting frame to drive the sliding box to rise and fall, the vacuuming component can be precisely connected to multiple steel cylinders to meet the needs of batch vacuuming. The setting of the connecting frame enhances the stress stability of the sliding box and avoids the sliding box tilting during the lifting process, which could lead to sealing failure.

[0011] Preferably, the sliding box is slidably connected inside the sealed chamber, the sliding box is fixedly connected to a connecting pipe, the connecting pipe is fixedly connected to the vacuum pump through a flexible hose, and the sliding tube is slidably connected inside the sliding box.

[0012] The above-mentioned structural design ensures that the sliding box and the sealed chamber have a precise lifting trajectory, preventing misalignment with the gas cylinder. The connecting pipe is connected to the vacuum pump through a flexible hose, which not only ensures the airtightness of the evacuation passage but also provides a flexible buffer for the lifting of the sliding box, preventing the pipe from being rigidly pulled and broken. The sliding connection design of the sliding pipe can adapt to the interface position of gas cylinders of different heights, improving the compatibility of the device.

[0013] Preferably, a spring rod is fixedly connected inside the sliding tube, one end of the spring rod is fixedly connected inside the sliding box, and a telescopic tube is slidably connected inside the sliding tube, with an opening in the telescopic tube.

[0014] With the above-mentioned structural design, the spring rod provides elastic buffer for the sliding tube. When the sliding tube comes into contact with the gas cylinder interface, the impact force can be absorbed by the spring compression to avoid damage to the interface by hard contact. The sliding design of the telescopic tube, together with the port, can go deep into the gas cylinder for evacuation, reduce the impact of residual gas at the bottle mouth on the vacuum level, and improve the vacuuming efficiency.

[0015] Preferably, the telescopic tube is fixedly connected to the connecting tube via a flexible hose, and a connecting air tube is also fixedly connected inside the sliding tube, with a connecting rod slidably connected inside the connecting air tube.

[0016] The design of the above structure ensures the continuity of the air extraction passage by connecting the telescopic tube and the connecting tube with a flexible hose, without affecting the sliding action of the telescopic tube. The cooperation between the connecting tube and the connecting rod forms an auxiliary sealing structure. When the telescopic tube moves, the connecting rod can slide synchronously with it, providing guidance for the subsequent sealing block to fit and ensuring the airtightness of the air extraction process.

[0017] Preferably, a second connecting rod is slidably connected inside the connecting tube. The first connecting rod is fixedly connected to the telescopic tube, and the second connecting rod is fixedly connected inside the sliding tube. A sealing block is fixedly connected to the top of both the first connecting rod and the second connecting rod.

[0018] With the above-mentioned structural design, the sliding cooperation between connecting rod one and connecting rod two in the connecting air pipe can drive the two sealing blocks to fit precisely, forming a double sealing structure, which effectively prevents gas leakage during the pumping process; the setting of the sealing blocks further enhances the airtightness at the interface, ensuring that the cylinder can reach the expected vacuum level, and solving the problem of poor vacuum effect caused by poor contact in traditional devices.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This application, through the setting of telescopic cylinder, motor, placement slot and connecting frame, realizes the function of enabling workers to operate multiple sets of gas cylinders at the same time, improves work efficiency, and solves the problem that the existing gas cylinder vacuuming devices are generally single in function, and are often inconvenient to operate multiple gas cylinders during use, which leads to a decrease in vacuuming efficiency and affects the working efficiency of the device.

[0021] 2. This application, through the setting of sliding tube, connecting rod one, connecting rod two, and sealing block, achieves the function of avoiding the situation where the connecting tube and the cylinder mouth are not in complete contact, thereby improving the vacuuming effect and solving the problem that existing cylinder vacuuming devices are prone to the situation where the connecting tube and the cylinder mouth are not in complete contact during vacuuming operations, thus affecting the vacuuming effect of the cylinder.

[0030] Combination Figures 1-3 An automatic vacuuming device for high-pressure steel cylinders includes a device body 1 and a sealed chamber 11 fixedly connected to one side of the device body 1. A controller 12 is also fixedly connected to one side of the device body 1. The device body 1 is provided with a placement mechanism, which serves to place multiple sets of high-pressure steel cylinders. The placement mechanism includes a motor 111 fixedly connected inside the device body 1. A heat dissipation groove for the motor 111 is opened on one side of the device body 1. A vacuum pump 121 is fixedly connected to one side of the controller 12. Multiple sets of vacuum pumps 121 are provided. A telescopic cylinder 13 is fixedly connected to the top of the device body 1.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the problem that existing gas cylinder vacuuming devices generally have limited functionality, making it inconvenient to operate on multiple gas cylinders and thus reducing vacuuming efficiency, this embodiment discloses the following technical solution, specifically as follows: Figures 1-3As shown, a screw 112 is fixedly connected to the output end of the motor 111. A sliding table 113 is threadedly connected to the screw 112. The sliding table 113 is slidably connected inside the sealed chamber 11. A placement slot 114 is provided on the top of the sliding table 113, and multiple placement slots 114 are provided. A connecting frame 131 is fixedly connected to the output end of the telescopic cylinder 13. A sliding box 132 is fixedly connected to the bottom of the connecting frame 131. The sliding box 132 is slidably connected inside the sealed chamber 11. A connecting pipe 133 is fixedly connected to the sliding box 132. The connecting pipe 133 is fixedly connected to the vacuum pump 121 through a flexible hose. When it is necessary to perform a vacuuming operation on the gas cylinder, the door on one side of the sealed chamber 11 can be opened, thereby starting the motor 111. Motor 111 drives screw 112 to rotate, thereby moving sliding table 113 out of the sealed chamber 11. At this time, the gas cylinder can be placed in the placement slot 114, and motor 111 is started in reverse to reset sliding table 113. Then telescopic cylinder 13 can be started, which drives connecting frame 131 to move, thereby making sliding box 132 slide inside sealed chamber 11. At this time, under the action of connecting pipe 133 and sliding pipe 14, the gas cylinder can be connected. Finally, controller 12 is controlled to start vacuum pump 121, thereby evacuating multiple gas cylinders. This realizes the function of allowing workers to operate multiple sets of gas cylinders at the same time, improving work efficiency.

[0034] Example 2:

[0035] To address the problem that existing gas cylinder vacuuming devices often fail to achieve complete contact between the connecting pipe 133 and the gas cylinder neck during vacuuming operations, thus affecting the vacuuming effect, this embodiment discloses the following technical solution, specifically as follows: Figure 4 and Figure 5As shown, a sliding tube 14 is slidably connected inside the sliding box 132. A spring rod 141 is fixedly connected inside the sliding tube 14, with one end of the spring rod 141 fixedly connected inside the sliding box 132. A telescopic tube 15 is slidably connected inside the sliding tube 14, and the telescopic tube 15 has an opening 151. The telescopic tube 15 is fixedly connected to the connecting tube 133 via a flexible hose. A connecting air tube 152 is also fixedly connected inside the sliding tube 14. A connecting rod 153 is slidably connected inside the connecting air tube 152, and a connecting rod 154 is also slidably connected inside the connecting air tube 152. The connecting rod 153 is fixedly connected to the telescopic tube 15, and the connecting rod 154 is fixedly connected inside the sliding tube 14. A sealing block 155 is fixedly connected to the top of both the connecting rod 153 and the connecting rod 154. When the telescopic cylinder 13 is activated, causing the sliding box 132 to descend, the sliding tube 14 first contacts the gas cylinder, thereby causing the sliding tube 152 to descend. 4. Movement: The sliding tube 14 moves, causing the connecting rod 154 to slide inside the connecting air pipe 152. Due to the sealing block 155, the air pressure causes the connecting rod 153 to slide inside the connecting air pipe 152, thereby moving the telescopic tube 15 into the cylinder. At this time, the telescopic tube 15 can be vacuumed through the port 151. Air is drawn away by the vacuum pump 121 through the telescopic tube 15 and the connecting tube 133. After the vacuuming operation is completed, the valve on the cylinder is closed, and the telescopic cylinder 13 is started in reverse. The telescopic cylinder 13 drives the sliding box 132 to move, thereby moving the telescopic tube 15. Under the action of the spring rod 141, the sliding tube 14 moves, causing the telescopic tube 15 to move back into the sliding tube 14. Finally, the cylinder can be removed from the sealed chamber 11. This achieves the effect of avoiding the situation where the connecting tube 133 and the cylinder mouth are not in complete contact, thus improving the vacuuming effect.
