Description

Technical Field

[0001] This application relates to the field of sulfuric acid preparation technology, specifically a fuming sulfuric acid sampling device. Background Technology

[0002] In the production process of fuming sulfuric acid, it is often necessary to sample the sulfuric acid to understand the product quality.

[0003] Chinese utility patent CN217586435U discloses a novel sampling structure for fuming sulfuric acid. It achieves stable sampling operations through the combination of a sampling tube and a sampling rod. However, the sampling rod is a fixed right angle, facilitating vertical movement of the sampling tube. When moving the sampling tube after it has been removed, the operator's hand is typically held horizontally. With the sampling rod vertical, the operator needs to change the hand's grip direction by raising their arm, increasing manual labor.

[0004] Therefore, this application provides a fuming sulfuric acid sampling device to solve the above problems. Utility Model Content

[0005] This application provides a fuming sulfuric acid sampling device, which aims to solve the problems mentioned in the background art, such as the existing sampling rod being fixed at a right angle, requiring the operator to change the hand grip direction when moving the sampling tube by raising the arm to make the grip direction vertical, thus increasing manpower consumption.

[0006] To achieve the above objectives, this application provides the following technical solution: a fuming sulfuric acid sampling device, comprising a sampling tube;

[0007] To facilitate adjustment of the mounting angle: the sampling tube is provided with a mounting clip for clamping the sampling tube on the outside; one end of the mounting clip is provided with a gripping component for moving the mounting clip; one end of the mounting clip is provided with a rotating component for rotating the mounting clip; and the gripping component is provided with a driving component for driving the rotating component inside. By attaching the mounting clip to the outside of the sampling tube and then moving the grip assembly by holding the anti-slip sleeve, the sampling tube can be moved. During the movement of the sampling tube, to reduce the force on the arm, fingers can be inserted through the insertion hole into the grip tube to rotate the turntable, thereby rotating the rotating rod. This causes the second bevel gear to rotate synchronously. Under the meshing action of the second and first bevel gears, the first bevel gear rotates, driving the linkage rod to rotate synchronously. The linkage rod then rotates the mounting clip, thus adjusting the angle between the sampling tube and the grip tube. This allows the operator to easily hold the grip tube without raising their arm, saving manpower. Holding the anti-slip sleeve prevents hand slippage. When the grip assembly is not in use for a long time, rotating the anti-slip sleeve will block the insertion hole, reducing the entry of foreign objects into the grip tube.

[0008] Preferably, for ease of hand gripping: the grip assembly includes a grip tube and a mounting tube fixedly disposed at one end of the grip tube for mounting the rotating component. The driving component is disposed inside the grip tube, and the outer wall of the grip tube has an insertion hole for operating the driving component. By mounting the driving component inside the grip tube and the rotating component inside the mounting tube, the rotating component and the driving component are stably mounted.

[0009] Preferably, to facilitate the installation of the rotating component: one end of the mounting tube is connected through to one end of the holding tube, and the other end of the mounting tube has a circular hole for inserting the rotating component. The rotating component includes a linkage rod fixedly connected to the outer wall of the mounting clip for driving the mounting clip to rotate, and a first bevel gear fixedly connected to the end of the linkage rod away from the mounting clip for driving the linkage rod to rotate. The linkage rod is inserted into the circular hole. By inserting the linkage rod into the circular hole and then meshing the first bevel gear with the second bevel gear, the mounting clip and the mounting tube are installed.

[0010] Preferably, to facilitate the rotation of the first bevel gear: the driving component includes a second bevel gear disposed on one side of the first bevel gear for meshing with it, a rotating rod fixedly inserted in the middle of the second bevel gear for driving its rotation, and a turntable fixedly sleeved on the end of the rotating rod away from the second bevel gear for driving the rotating rod to rotate. By rotating the turntable, the rotating rod is driven to rotate, causing the rotating rod to drive the second bevel gear to rotate. Under the action of the second bevel gear meshing with the first bevel gear, the mounting clip is driven to rotate via the linkage rod, allowing for multi-angle adjustment of the mounting clip.

[0011] Preferably, to facilitate the installation of the drive component: bearings are respectively fitted at both ends of the rotating rod, and sealing members for closing the gripping tube are respectively fixedly connected to both ends of the gripping tube. The sealing member includes a sealing plate fixedly disposed at the end of the gripping tube for closing the gripping tube, and a mounting seat fixedly disposed on the side of the sealing plate facing the gripping tube for mounting the bearings. The drive component is installed inside the mounting seat by the bearings, and then fixedly connected to the gripping tube by the sealing plate, thereby completing the installation of the drive component inside the gripping tube.

[0012] Preferably, to prevent slippage when holding the grip tube: the outer wall of the grip tube is fitted with an anti-slip sleeve to prevent slippage, and the insertion hole penetrates the anti-slip sleeve. The anti-slip sleeve prevents the grip tube from slipping and falling when held.

[0013] This application, through the design of a gripping component, a rotating component, a driving component, an insertion hole, and an anti-slip sleeve, utilizes a design where the mounting clip is attached to the outside of the sampling tube. By gripping the anti-slip sleeve, the gripping component moves, thereby moving the mounting clip and ultimately the sampling tube. To reduce strain on the arm during movement, fingers can be inserted through the insertion hole into the gripping tube to rotate the turntable, which in turn rotates the rotating rod. This causes the second bevel gear to rotate synchronously. The meshing of the second and first bevel gears causes the first bevel gear to rotate, which in turn rotates the linkage rod. The linkage rod then rotates the mounting clip, allowing for angle adjustment between the sampling tube and the gripping tube. This design allows workers to easily handle the tube without raising their arms, saving manpower. The anti-slip sleeve prevents hand slippage. When the gripping component is not in use for extended periods, rotating the anti-slip sleeve blocks the insertion hole, reducing the entry of foreign objects into the gripping tube.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This embodiment provides a fuming sulfuric acid sampling device, such as... Figure 1-7 As shown, the sampling device includes a sampling tube 1;

[0025] To facilitate adjustment of the angle of the mounting clip 2: A mounting clip 2 for holding the sampling tube 1 is provided on the outside of the sampling tube 1. A gripping component 3 for moving the mounting clip 2 is provided at one end of the mounting clip 2, and a rotating component 4 for rotating the mounting clip 2 is provided at the other end. A driving component 5 for driving the rotating component 4 is provided inside the gripping component 3. By attaching the mounting clip 2 to the outside of the sampling tube 1, and then moving the gripping component 3 by gripping the anti-slip sleeve 8, the sampling tube 1 is moved. During the movement of the sampling tube 1, to reduce the force on the arm, fingers can be inserted into the gripping tube 31 through the insertion hole 7 to rotate the turntable 53, thereby rotating the rotating rod 52. This causes the second bevel gear 51 to rotate synchronously. Under the meshing action of the second bevel gear 51 and the first bevel gear 42, the first bevel gear 42... The rotation of the first bevel gear 42 drives the linkage rod 41 to rotate synchronously, and the linkage rod 41 drives the mounting clip 2 to rotate at an angle, thereby realizing the angle adjustment between the sampling tube 1 and the holding tube 31. This allows the staff to hold the holding tube 31 without raising their arms, saving manpower. The anti-slip sleeve 8 can prevent the hand from slipping. When the holding component 3 is not used for a long time, the anti-slip sleeve 8 can be rotated to block the insertion hole 7, reducing the entry of foreign objects into the holding tube 31.

[0026] Furthermore, the sampling tube 1 and the mounting card 2 are made of glass, and the shape and working principle of the sampling tube 1 and the mounting card 2 are the same as those of the sampling tube 1 and the sampling ring 6 in CN217586435U.

[0027] Specifically, for ease of hand gripping: the grip assembly 3 includes a grip tube 31 and a mounting tube 32 fixedly disposed at one end of the grip tube 31 for mounting the rotating component 4. The driving component 5 is disposed inside the grip tube 31, and the outer wall of the grip tube 31 has an insertion hole 7 for operating the driving component 5. By installing the driving component 5 inside the grip tube 31 and the rotating component 4 inside the mounting tube 32, the rotating component 4 and the driving component 5 are stably installed. The grip tube 31 and the mounting tube 32 are arranged perpendicular to each other, and the contact parts of the grip tube 31 and the mounting tube 32 are welded and fixed. The grip tube 31 and the mounting tube 32 are interconnected, so that the second bevel gear 51 and the first bevel gear 42 mesh with each other. The insertion hole 7 passes through the grip tube 31 and the anti-slip sleeve 8, so that fingers can be inserted into the grip tube 31 through the insertion hole 7 to rotate the turntable 53. By gripping the grip tube 31, the mounting clip 2 can be moved.

[0028] Specifically, to facilitate the installation of the rotating component 4: one end of the mounting tube 32 is connected to one end of the holding tube 31, and the other end of the mounting tube 32 has a circular hole for inserting the rotating component 4. The rotating component 4 includes a linkage rod 41 fixedly connected to the outer wall of the mounting clip 2 for driving the mounting clip 2 to rotate, and a first bevel gear 42 fixedly connected to the end of the linkage rod 41 away from the mounting clip 2 for driving the linkage rod 41 to rotate. The linkage rod 41 is inserted into the circular hole. By inserting the linkage rod 41 into the inside of the circular hole, and then meshing the first bevel gear 42 with the second bevel gear 51, the mounting clip 2 and the mounting tube 32 are installed. The diameter of the linkage rod 41 is adapted to the size of the circular hole, and the length of the linkage rod 41 corresponds to the thickness of the circular hole, so that the first bevel gear 42 and the mounting clip 2 are located on both sides of the circular hole, restricting the movement of the linkage rod 41 and allowing only the rotation of the linkage rod 41. The mounting clip 2 is bonded to the linkage rod 41, and the linkage rod 41 is welded to the first bevel gear 42.

[0029] More specifically, to facilitate the rotation of the first bevel gear 42: the driving component 5 includes a second bevel gear 51 disposed on one side of the first bevel gear 42 for meshing with it, a rotating rod 52 fixedly inserted through the middle of the second bevel gear 51 for driving the second bevel gear 51 to rotate, and a turntable 53 fixedly sleeved on the end of the rotating rod 52 away from the second bevel gear 51 for driving the rotating rod 52 to rotate. By rotating the turntable 53, the rotating rod 52 is driven to rotate, causing the rotating rod 52 to drive the second bevel gear 51 to rotate. Under the action of the second bevel gear 51 meshing with the first bevel gear 42, the mounting clip 2 is driven to rotate through the linkage rod 41, allowing for multi-angle adjustment of the mounting clip 2. The turntable 53 and the second bevel gear 51 are respectively disposed at both ends of the rotating rod 52, and the parts of the turntable 53 and the second bevel gear 51 that contact the rotating rod 52 are welded and fixed.

[0030] Furthermore, to facilitate the installation of the drive component 5: bearings 54 are respectively fitted at both ends of the rotating rod 52, and sealing components 6 for closing the gripping tube 31 are respectively fixedly connected to both ends of the gripping tube 31. The sealing component 6 includes a sealing plate 61 fixedly disposed at the end of the gripping tube 31 for closing the gripping tube 31, and a mounting seat 62 fixedly disposed on the side of the sealing plate 61 facing the gripping tube 31 for mounting the bearings 54. The drive component 5 is installed inside the mounting seat 62 by the bearings 54, and then fixedly connected to the gripping tube 31 by the sealing plate 61, thereby completing the installation of the drive component 5 inside the gripping tube 31. Two symmetrical sealing members 6 are arranged at the two ends of the gripping tube 31. The sealing plate 61 is fixedly connected to the gripping tube 31 by bolts. The sealing plate 61 is welded and fixed to the contact part of the mounting base 62. The inner diameter of the mounting base 62 is adapted to the outer diameter of the bearing 54. The inner ring of the bearing 54 is welded and fixed to the outer wall of the end of the rotating rod 52. The bearing 54 is sleeved inside the mounting base 62. Two bearings 54 are arranged at the outer walls of the two ends of the rotating rod 52. The two bearings 54 are installed inside the two mounting bases 62 respectively. Then, the two sealing plates 61 are fixedly connected to the end of the gripping tube 31 to achieve stable installation of the driving member 5 inside the gripping tube 31 and restrict the driving member 5 to only rotate.

[0031] Specifically, to prevent slippage when holding the grip tube 31, an anti-slip sleeve 8 is fitted onto the outer wall of the grip tube 31, with an insertion hole 7 penetrating through the anti-slip sleeve 8. The anti-slip sleeve 8 prevents the grip tube 31 from slipping and falling when held. The outer wall of the anti-slip sleeve 8 has anti-slip textures. The anti-slip sleeve 8 is made of rubber and is fitted onto the outer wall of the grip tube 31. The inner wall of the anti-slip sleeve 8 is attached to the outer wall of the grip tube 31 through friction. Through the insertion hole 7 penetrating both the anti-slip sleeve 8 and the grip tube 31, fingers can be inserted into the grip tube 31 to rotate the turntable 53. When not in use for an extended period, the anti-slip sleeve 8 can be rotated to offset the position of the insertion hole 7, thus preventing foreign objects from entering the grip tube 31 through the insertion hole 7.

[0032] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
