TECHNICAL FIELD

[0001] The utility model relates to vacuum device technical field especially relates to a multi -tube jet flow vacuum device. BACKGROUND

[0002] Vacuum pump refers to the device or equipment that carries out pumping to the container to be pumped and obtains vacuum by mechanical, physical, chemical or physical and chemical methods, and the current vacuum device or vacuum pump mainly has three kinds: single -tube vacuum device or vacuum pump, water injection single -tube vacuum pump and water jet steam extractor.

[0003] The height of the bottom water outlet of the existing water injection vacuum pump is inconvenient to adjust when in use, and the overall installation position of the device and the setting position of the water storage tank are limited.

[0004] Therefore, in view of the fact that the height of the water outlet of the existing water injection vacuum pump is not easy to adjust when in use, a multi -tube jet flow vacuum device can be designed, which is provided with a driving motor, and the output end of the driving motor drives the driving gear to rotate when working, and the driving gear drives the driven gear meshing therewith to rotate, thereby driving the rotary sealing seat to rotate, and the rotary sealing seat drives the water outlet pipe connected therewith to realize up and down lifting, thereby adjusting the position of the water outlet. UTILITY MODEL CONTENTS

[0005] In order to overcome the problem that the height of the bottom water outlet of the existing water injection vacuum pump is inconvenient to adjust when in use, resulting in limited installation position.

[0006] The technical scheme of the utility model is as follows: a multi -tube jet flow vacuum device, comprising a condenser; further comprising a mounting disc, a driving motor, a driving gear and a driven gear, a condenser is provided with a condensate outlet in the middle of the bottom surface, a water injector is connected to the right side surface of the condenser through a pipeline, a pressure water inlet is installed on the top surface of the water injector, a connecting assembly is arranged on the bottom surface of the water injector, a connecting disc is connected to the bottom of the connecting assembly, a guide pipe is installed on the outer edge of the bottom surface of the connecting disc, an outlet pipe is inserted into the middle of the bottom surface of the guide pipe, a rotary sealing seat is threadedly connected to the outer surface of the outlet pipe, the upper surface of the rotary sealing seat is rotatably connected to the bottom surface of the guide pipe, a mounting disc is installed on the lower position of the outer surface of the guide pipe, a driving motor is installed on the right position of the upper surface of the mounting disc, a driving gear is arranged on the output end of the driving motor, a driven gear is arranged on the bottom surface of the rotary sealing seat, and the driving gear is meshed with the driven gear.

[0007] Preferably, by setting a drive motor, its output end will drive the drive gear to rotate during operation. The drive gear drives the driven gear meshing with it to rotate, thereby driving the rotary seal seat to rotate. The rotary seal seat drives the water outlet pipe connected to it to move up and down, thereby adjusting the position of the water outlet. This solves the problems of existing multi-pipe jet flow vacuum devices, where the position of the water outlet is fixed and inconvenient to adjust. During installation, it is necessary to select a suitable installation height and the location of the water storage tank according to the height of the water outlet and the length of the outlet pipe. It is greatly affected by the installation environment and has certain limitations.

[0008] Preferably, the connecting assembly includes a first conical tube, a connecting tube, and a second conical tube. Five first conical tubes are circumferentially distributed on the bottom surface of the water jet, and the bottom surfaces of the five first conical tubes are all connected to connecting tubes. The bottom surfaces of the connecting tubes are connected to the upper surface of the connecting plate. By setting the connecting assembly, the combination of the first conical tube, the connecting tube, and the second conical tube forms a pipe that is thicker at both ends and thinner in the middle, which can improve the pressure resistance of the entire connecting assembly and ensure that the connecting assembly can be used safely in a high-pressure environment.

[0009] Preferably, a gas supply pipe is connected to the lower left side surface of the condenser via a pipeline, and a steam ejector is connected to the upper part of the gas supply pipe via a connecting assembly. An air extraction port is installed on the upper left side surface of the steam ejector. By setting up the steam ejector, in conjunction with the water ejector, a multi-stage combination of steam injection and water injection can be achieved, which greatly improves the air extraction capacity, enables the vacuum system to reach the ultimate vacuum, increases the back pressure of the equipment, and significantly improves the production capacity of the entire system.

[0010] Preferably, one end of the drain pipe is connected to the center of the bottom surface of the connecting plate, and the other end of the drain pipe is inserted into the top of the outlet pipe. The drain pipe and the outlet pipe are slidably connected. By setting the drain pipe, the drain pipe is inserted into the interior of the outlet pipe and extends downward for a certain length. When the outlet pipe moves up and down, it can be ensured that the bottom end of the drain pipe is still inside the outlet pipe, ensuring that the introduced high-pressure water can be discharged smoothly.

[0011] Preferably, a limiting ring is rotatably connected to the outer edge of the bottom surface of the mounting plate. The inner surface of the limiting ring is equipped with circumferentially distributed meshing teeth that mesh with the drive gear. By setting the limiting ring, when the drive gear rotates, it will drive the limiting ring to rotate in cooperation with the meshing teeth, thereby improving the stability of the entire transmission structure and preventing the drive gear from falling off.

[0012] Preferably, a baffle is installed on the upper part of the outer surface of the water outlet pipe. The baffle is welded to the water outlet pipe. By setting the baffle, after the water outlet pipe descends to a certain distance, the baffle on its outer surface will contact the lower end of the inner surface of the guide pipe, thereby preventing the water outlet pipe from descending further and avoiding the problem that the bottom end of the drain pipe will detach from the inside of the water outlet pipe, causing the internal high-pressure water to be unable to be discharged smoothly.

[0013] Preferably, the lower end of the outer surface of the condenser is provided with three circumferentially distributed support legs, and a pressure gauge is installed in the middle of the top surface of the condenser. The three support legs can improve the load-bearing capacity of the condenser and ensure the stability of the device during use. In addition, the pressure gauge can make it easy for the staff to check the internal pressure of the equipment in real time and ensure that the internal pressure is within the safe threshold.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a drive motor, its output end will drive the active gear to rotate during operation. The active gear drives the driven gear meshing with it to rotate, thereby driving the rotary seal seat to rotate. The rotary seal seat drives the water outlet pipe connected to it to move up and down, thereby adjusting the position of the water outlet. This solves the problems of existing multi-pipe jet flow vacuum devices, where the position of the water outlet is fixed and inconvenient to adjust. During installation, it is necessary to select a suitable installation height and the location of the water storage tank according to the height of the water outlet and the length of the outlet pipe. It is greatly affected by the installation environment and has certain limitations. Attached Figure Description

The drive gear 18 and the driven gear 19 mesh. By setting the drive motor 17, its output end will drive the drive gear 18 to rotate during operation. The drive gear 18 drives the driven gear 19 that meshes with it to rotate, thereby driving the rotary sealing seat 15 to rotate. The rotary sealing seat 15 drives the water outlet pipe 14 that is threaded to it to move up and down, thereby adjusting the position of the water outlet.

[0023] Please see Figure 1 , Figure 2 and Figure 4In this embodiment, the connecting assembly includes a first conical tube 111, a connecting tube 112, and a second conical tube 113. Five circumferentially distributed first conical tubes 111 are mounted on the bottom surface of the water jet 8. Each of the five first conical tubes 111 is connected to a connecting tube 112 on its bottom surface. A second conical tube 113 is mounted on the bottom surface of each connecting tube 112, and the bottom surface of the second conical tube 113 is connected to the upper surface of the connecting plate 10. By setting up the connecting assembly, the combination of the first conical tube 111, the connecting tube 112, and the second conical tube 113 forms a pipe that is thicker at both ends and thinner in the middle, which can improve the pressure resistance of the entire connecting assembly and ensure that the connecting assembly can be used safely under high pressure. A gas supply pipe 5 is connected to the lower left side surface of the condenser 1 via a pipe. A connecting tube is connected to the upper part of the gas supply pipe 5 via a connecting... The component is connected to a steam ejector 6. An air extraction port 7 is installed on the upper left side surface of the steam ejector 6. By setting the steam ejector 6, in conjunction with the water ejector 8, a multi-stage combination of steam injection and water injection can be achieved, which greatly improves the air extraction capacity, enables the vacuum system to reach the ultimate vacuum, increases the equipment back pressure, and significantly improves the overall system production capacity. One end of the drain pipe 13 is connected to the center of the bottom surface of the connecting plate 10. The other end of the drain pipe 13 is inserted into the top of the water outlet pipe 14. The drain pipe 13 and the water outlet pipe 14 are slidably connected. By setting the drain pipe 13, the drain pipe 13 is inserted into the interior of the water outlet pipe 14 and extends downward for a certain length. When the water outlet pipe 14 moves up and down, it can be ensured that the bottom end of the drain pipe 13 is still inside the water outlet pipe 14, ensuring that the introduced high-pressure water can be discharged smoothly.

[0024] Please see Figures 1-4 In this embodiment, a limiting ring 20 is rotatably connected to the outer edge of the bottom surface of the mounting plate 16. The inner surface of the limiting ring 20 is equipped with circumferentially distributed meshing teeth 21, which mesh with the drive gear 18. By setting the limiting ring 20, when the drive gear 18 rotates, it will drive the limiting ring 20 to rotate in cooperation with the meshing teeth 21, thereby improving the stability of the entire transmission structure and preventing the drive gear 18 from falling off. A baffle 22 is installed on the upper part of the outer surface of the water outlet pipe 14. The baffle 22 is welded to the water outlet pipe 14. By setting the baffle 22, when the water outlet pipe 14 descends to a certain position... After a certain distance, the baffle 22 on its outer surface will contact the lower end of the inner surface of the guide pipe 12, thereby preventing the outlet pipe 14 from continuing to descend and avoiding the problem that the bottom end of the drain pipe 13 will detach from the interior of the outlet pipe 14, causing the internal high-pressure water to be unable to be discharged smoothly. The lower end of the outer surface of the condenser 1 is provided with three circumferentially distributed support legs 3. A pressure gauge 4 is installed in the middle of the top surface of the condenser 1. By setting three support legs 3, the load-bearing capacity of the condenser 1 can be improved and the stability of the device during use can be ensured. Furthermore, by setting a pressure gauge 4, it is convenient for staff to check the internal pressure of the equipment in real time and ensure that the internal pressure is within the safe threshold.

[0025] During operation, by setting up a connecting assembly, the combination of the first tapered pipe 111, the connecting pipe 112, and the second tapered pipe 113 forms a pipe that is thicker at both ends and thinner in the middle. This improves the pressure resistance of the entire connecting assembly, ensuring its safe use under high pressure. Furthermore, by setting up the steam ejector 6, in conjunction with the water ejector 8, multi-stage steam and water jet injection can be combined, significantly improving the pumping capacity, enabling the vacuum system to reach its ultimate vacuum, increasing the equipment back pressure, and greatly enhancing the overall system's production capacity. Finally, by setting up the drain pipe 13, which is inserted into the outlet pipe 14 and extends downwards by a certain length, the bottom end of the drain pipe 13 remains inside the outlet pipe 14 when the outlet pipe 14 moves up and down, ensuring that the introduced high-pressure water can be smoothly discharged. Furthermore, by setting a limiting ring 20, when the drive gear 18 rotates, it will drive the limiting ring 20 to rotate in cooperation with the meshing teeth 21, thereby improving the stability of the entire transmission structure and preventing the drive gear 18 from falling off. In addition, by setting a baffle 22, after the water outlet pipe 14 descends to a certain distance, the baffle 22 on its outer surface will contact the lower end of the inner surface of the guide pipe 12, thereby preventing the water outlet pipe 14 from continuing to descend, and preventing the bottom end of the drain pipe 13 from leaving the inside of the water outlet pipe 14, which would cause the internal high-pressure water to be unable to be discharged smoothly. In addition, by setting three support legs 3, the load-bearing capacity of the condenser 1 can be improved and the stability of the device during use can be ensured. Furthermore, by setting a pressure gauge 4, it is convenient for the staff to check the internal pressure of the equipment in real time and ensure that the internal pressure is within the safe threshold.

[0026] Through the above steps, by setting the drive motor 17, its output end will drive the drive gear 18 to rotate during operation. The drive gear 18 drives the driven gear 19 meshing with it to rotate, thereby driving the rotary sealing seat 15 to rotate. The rotary sealing seat 15 drives the water outlet pipe 14 threaded to it to move up and down, thereby adjusting the position of the water outlet. This solves the problems of existing multi-pipe jet flow vacuum devices, where the position of the water outlet is fixed and inconvenient to adjust, and the installation height and the position of the water storage tank need to be selected according to the height of the water outlet and the length of the outlet pipe. The installation is greatly affected by the installation environment and has certain limitations.
