Description

Technical Field

[0001] The utility model relates to the technical field of vacuum pumps, in particular to a pipeline protection structure which is convenient for disassembly and assembly. Background Technique

[0002] A vacuum pump refers to a device or equipment that uses mechanical, physical, chemical, or physical-chemical methods to evacuate a container to be evacuated to obtain a vacuum. Generally speaking, a vacuum pump is a device that improves, generates, and maintains a vacuum in a closed space by various methods. When using a vacuum pump, the air inlet evacuates the container to be evacuated. Since there may be impurities in the container to be evacuated, generally a pipeline-shaped filtering and protecting structure is arranged between the vacuum pump and the container to be evacuated to protect the vacuum pump.

[0003] Chinese Patent (the authorization announcement number is: CN220090800U, and the authorization announcement date is: November 28, 2023) proposed a pre-filter for a vacuum pump, which relates to the field of vacuum pumps and includes a vacuum pump body. A upper filter barrel and a lower filter barrel are arranged on one side of the vacuum pump body. A filter hopper is installed on the upper filter barrel through a rotation driving assembly, and a top plate is arranged on the filter hopper.

[0004] For this disclosed technology, in the existing pipeline protection structure, when the filter screen blocks impurities, the impurities may block the filter holes of the filter screen. Therefore, it is necessary to disassemble and clean the filter screen. However, when the existing filter screen is removed, since most pipelines are fixed by a plurality of nuts, it will be more inconvenient to clean the filter screen at this time. At the same time, the pipeline protection structure generally only simply blocks and filters impurities. If there are corrosive gases in the container to be evacuated, it will also damage the internal structure of the vacuum pump. For this reason, we propose a pipeline protection structure which is convenient for disassembly and assembly. Content of the Utility Model

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Such as Figure 1-8As shown in the figure, it includes a left pipeline 1 and a right pipeline 2. A docking component 3 for quick disassembly and assembly is arranged on the surface of the left pipeline 1, and a connection component 4 for quick disassembly and assembly is arranged on the surface of the right pipeline 2.

The filtering component 8 includes a filter screen 803, and adsorption particles are filled in the purification component 9. Specifically, for this pipeline protection structure that is easy to disassemble and assemble, through the setting of the inlet and outlet components 12, this protection structure can be connected between the vacuum pump and the structure to be extracted. The setting of the docking component 3 and the connection component 4 can dock the left pipeline 1 and the right pipeline 2. At the same time, a sealing structure is arranged on the docking component 3, so that the sealing performance of the connection between the left pipeline 1 and the right pipeline 2 can be guaranteed. Through the setting of the clamping component 6, the connection between the docking component 3 and the connection component 4 can be initially limited and fixed. Through the setting of the locking component 7, the docking component 3 and the connection component 4 can be locked and fixed, thereby completing the connection between the left pipeline 1 and the right pipeline 2. At this time, while the left pipeline 1 and the right pipeline 2 can be quickly docked, they can be fixed through the locking component 7, which facilitates the disassembly and assembly process of the left pipeline 1 and the right pipeline 2. Through the setting of the filtering component 8 inside the left pipeline 1, dust and other impurities extracted from the structure to be extracted can be blocked, thereby protecting the vacuum pump. The setting of the purification component 9, with adsorption particles arranged in the purification component 9, can adsorb the extracted corrosive gas, thereby protecting the internal structure of the vacuum pump. The setting of the pressure gauge 11, with a threshold value set on the pressure gauge 11, if the detected pressure is lower than the threshold value, an alarm is issued to prompt that the filtering structure is blocked and needs to be replaced. At this time, the left pipeline 1 and the right pipeline 2 can be conveniently disassembled and assembled. At the same time, the filtering structure is connected to the left pipeline 1 by means of threaded installation, so that the filtering structure can be conveniently cleaned. At the same time, an adsorption structure for corrosive gas is set, which can further protect the internal structure of the vacuum pump.

[0032] As Figure 2 、 Figure 6As shown in the figure, the docking component 3 includes a collar 301. The collar 301 is fixedly sleeved on the surface of the left pipe 1. A docking block 302 is fixedly connected to the surface of the collar 301, and a clamping groove 5 is formed on the surface of the docking block 302. A notch 303 is formed on the surface of the left pipe 1, and an O-ring 304 is movably sleeved on the inner wall of the notch 303. Specifically, for the setting of the docking component 3, the collar 301 is used for connecting the locking component 7. The docking block 302 is used for preliminary plugging and fixing with the connecting component 4. The setting of the O-ring 304 can ensure the sealing performance between the two joints after the connecting component 4 is docked.

[0033] As Figure 5 shown in the figure, the connecting component 4 includes a fixing ring 401. The fixing ring 401 is fixedly sleeved on the surface of the right pipe 2. A sealing ring 402 is fixedly connected to the surface of the fixing ring 401, and the inner wall of the sealing ring 402 is in contact with the O-ring 304. A slot 403 is formed on the surface of the fixing ring 401, and the docking block 302 is movably inserted into the slot 403. Specifically, for the setting of the connecting component 4, the fixing ring 401 is used for connecting the sealing ring 402 and at the same time cooperates with the tightening process of the locking component 7. After the docking component 3 and the connecting component 4 are connected, the sealing ring 402 can be inserted into the surface of the left pipe 1. The inner wall of the sealing ring 402 is in contact with the O-ring 304 to ensure its sealing performance. The slot 403 is used for inserting and connecting the docking block 302.

[0034] As Figure 4As shown in the figure, the clamping component 6 includes a clamping block 603. A component slot 601 is formed inside the fixed ring 401. A moving port 602 is formed on the inner wall of the component slot 601. The clamping block 603 is movably inserted into the moving port 602. A plug rod 604 is fixedly connected to the surface of the clamping block 603, and the plug rod 604 is movably inserted into the fixed ring 401. A spring 605 is fixedly connected to the surface of the clamping block 603, and the spring 605 is connected to the component slot 601. A slide rail 606 is fixedly connected to the inner wall of the component slot 601. A limit slider 607 is slidably connected to the inner wall of the slide rail 606, and the limit slider 607 is fixedly connected to the clamping block 603. Specifically, for the setting of the clamping component 6, after operating the locking component 7, the plug rod 604 is pulled. At this time, the clamping block 603 moves into the interior of the component slot 601 through the moving port 602, and the spring 605 is compressed and contracted. The limit slider 607 slides on the slide rail 606 to assist the movement process of the clamping block 603. At this time, the clamping block 603 moves out of the clamping slot 5 on the surface of the docking block 302. At this time, the docking block 302 can be moved out of the slot 403, and the sealing ring 402 is pulled out from the surface of the left pipe 1, that is, the left pipe 1 and the right pipe 2 are separated. At this time, the filter component 8 can be cleaned, and at the same time, the impurities blocking the inside of the left pipe 1 can be cleaned, and at the same time, the purification component 9 inside the right pipe 2 can be replaced. During installation, first, the docking block 302 is aligned and inserted into the slot 403. Similarly, the plug rod 604 is pulled. After the docking block 302 is inserted, at this time, the sealing ring 402 is inserted into the surface of the left pipe 1, and the inner wall of the sealing ring 402 is fitted with the O-ring 304, thereby ensuring the sealing performance of the connection. The plug rod 604 is released. At this time, the resilience of the spring 605 drives the clamping block 603 to move, and the clamping block 603 moves and is clamped into the clamping slot 5 on the surface of the docking block 302, initially fixing the connection between the docking component 3 and the connection component 4. At the same time, through clamping and limiting, it is convenient to operate the locking component 7. At this time, the left pipe 1 and the right pipe 2 can be easily disassembled and assembled, thereby facilitating the cleaning or replacement of their internal structures.

[0035] As Figure 2 shown, the locking component 7 includes a locking screw 701. The locking screw 701 is rotatably connected to the inner wall of the collar 301. A butterfly nut 702 is threadedly connected to the surface of the locking screw 701, and the butterfly nut 702 is in contact with the fixed ring 401. Specifically, for the setting of the locking component 7, the locking screw 701 can rotate on the collar 301. By screwing the butterfly nut 702, the butterfly nut 702 is in contact with the surface of the fixed ring 401, and the docking component 3 and the connection component 4 can be locked and fixed, making the connection between the left pipe 1 and the right pipe 2 stable.

[0036] As Figure 3 、 Figure 8As shown, the filtering component 8 further includes a connecting frame 801. The inner wall of the left pipeline 1 is threadedly connected to the connecting frame 801. A handle 802 is fixedly connected to the inner wall of the connecting frame 801, and a filter net 803 is installed inside the connecting frame 801. Specifically, due to the setting of the filtering component 8, the connecting frame 801 is threadedly connected inside the left pipeline 1. By rotating the connecting frame 801 through the handle 802, the connecting frame 801 can be rotated out of the left pipeline 1. At this time, the surface of the filter net 803 can be cleaned, and at the same time, the filter net 803 can block and filter impurities.

[0037] As Figure 7 , Figure 8 shown, the purification component 9 includes a magnetic attraction block 901. The magnetic attraction block 901 is fixedly connected to the inner wall of the right pipeline 2. A placement frame 902 is attached to the surface of the magnetic attraction block 901, and the blocking cloth 10 is connected to the surface of the placement frame 902. Adsorption particles are filled inside the placement frame 902, and a feed pipe 903 is provided on the surface of the placement frame 902. Specifically, due to the setting of the purification component 9, the magnetic attraction block 901 adsorbs and fixes the placement frame 902, so that the magnetic attraction block 901 can also be removed to replace the adsorption particles. The adsorption particles can be loaded into the placement frame 902 through the feed pipe 903. Due to the setting of the blocking cloth 10, gas can pass through the placement frame 902, and the adsorption particles inside the placement frame 902 can adsorb corrosive gas to protect the internal structure of the vacuum pump.

[0038] As Figure 1 , Figure 7 shown, the inlet and outlet component 12 includes an inlet pipe 1201. The inlet pipe 1201 is provided on the side of the left pipeline 1, and an outlet pipe 1202 is provided on the side of the right pipeline 2. Specifically, due to the setting of the inlet and outlet component 12, the inlet pipe 1201 is connected to the port of the structure to be extracted, and the outlet pipe 1202 is connected to the inlet of the vacuum pump, connecting this protection structure between the vacuum pump and the structure to be extracted.

[0039] As Figure 1 , Figure 6 shown, the number of the docking blocks 302 is two, and the two docking blocks 302 are symmetrically distributed on the surface of the collar 301. Specifically, due to the setting of the two docking blocks 302, after the docking component 3 and the connecting component 4 are initially connected, the connection between the two can be more stable, facilitating the operation of the locking component 7.

[0040] As Figure 7 , Figure 8As shown, the placement frame 902 is made of metal. There are two feed pipes 903, and the two feed pipes 903 are symmetrically distributed on the surface of the magnetic attraction block 901. Specifically, the placement frame 902 made of metal can be adsorbed and connected by the magnetic attraction block 901, and the two feed pipes 903 enable the adsorbed particles to be removed from the placement frame 902 more conveniently.

[0041] Working principle: For this easily disassembled and assembled pipeline protection structure, through the setting of the inlet and outlet component 12, the protection structure can be connected between the vacuum pump and the structure to be extracted. When the vacuum pump operates, gas flows from the left pipeline 1 to the right pipeline 2. The pressure gauge 11 is set with a threshold value. If the detected pressure is lower than the threshold value, an alarm is issued to indicate that the filter component 8 is blocked and needs to be replaced. At this time, through the setting of the docking component 3 and the connecting component 4, the left pipeline 1 and the right pipeline 2 can be docked. When disassembling, first operate the locking component 7 and turn the butterfly nut 702 so that the butterfly nut 702 leaves the surface of the fixing ring 401, and then turn the locking screw 701 to release the fixation between the docking component 3 and the connecting component 4. Subsequently, operate the clamping component 6 and pull the insertion rod 604. At this time, the clamping block 603 moves through the moving port 602 into the component slot 601, and the spring 605 is squeezed and contracted. The limiting slider 607 slides on the slide rail 606 to assist the movement process of the clamping block 603. At this time, the clamping block 603 moves out of the clamping groove 5 on the surface of the docking block 302, and then the docking block 302 can be removed from the slot 403. The sealing ring 402 is pulled out from the surface of the left pipeline 1, separating the left pipeline 1 and the right pipeline 2. The filter component 8 is set with the connecting frame 801 threadedly connected inside the left pipeline 1. By turning the connecting frame 801 with the handle 802, the connecting frame 801 can be rotated out of the left pipeline 1. At this time, the surface of the filter net 803 can be cleaned, and at the same time, the impurities blocking in the left pipeline 1 can be removed. Subsequently, the left pipeline 1 and the right pipeline 2 can be installed. First, align the docking block 302 and insert it into the slot 403. Similarly, pull the insertion rod 604. After the docking block 302 is inserted, at this time, the sealing ring 402 is inserted onto the surface of the left pipeline 1, and the inner wall of the sealing ring 402 fits with the O-ring 304, thus ensuring the sealing performance of the connection. Release the insertion rod 604. At this time, the resilience of the spring 605 drives the clamping block 603 to move, and the clamping block 603 moves and snaps into the clamping groove 5 on the surface of the docking block 302 to initially fix the connection between the docking component 3 and the connecting component 4. At the same time, through the clamping limit, it is convenient to operate the locking component 7. Subsequently, flip the locking screw 701. Similarly, turn the butterfly nut 702 to fit with the surface of the fixing ring 401, and the connection between the collar 301 and the fixing ring 401 can be locked and fixed, completing the connection and fixation between the left pipeline 1 and the right pipeline 2. At this time, the left pipeline 1 and the right pipeline 2 can be easily disassembled and assembled. The purification component 9 is set with the magnetic attraction block 901 adsorbing and fixing the placement frame 902, so that the magnetic attraction block 901 can also be removed to replace the adsorbed particles. The adsorption particles can be loaded into the placement frame 902 through the feed pipe 903 inside the placement frame 902. The blocking cloth 10 is set so that gas can pass through the placement frame 902, and the adsorption particles inside the placement frame 902 can adsorb the corrosive gas.
