Abstract
Description
Technical Field
[0001] This application relates to the technical field of scrubbers, and specifically to a self-locking inner tower component pressing device. Background Technique
[0002] Scrubbers are commonly used equipment for acid-base exhaust gas treatment at present. Various packing devices and inner tower components can be designed inside the tower to meet the process treatment requirements.
[0003] Scrubbers generally adopt an air extraction design with negative pressure inside the tower. Due to large airflow changes, the fixing bolts on the inner tower components are prone to loosen due to the airflow, resulting in the locking failure of the bolts on the inner tower components, causing gaps between the inner tower components and the scrubber, and reducing the washing effect.
[0004] Therefore, this application provides a self-locking inner tower component pressing device to solve the above problems. Utility Model Content
[0005] This application provides a self-locking inner tower component pressing device, aiming to solve the problems in the background technique that the existing scrubbers generally adopt an air extraction design with negative pressure inside the tower. Due to large airflow changes, the fixing bolts on the inner tower components are prone to loosen due to the airflow, resulting in the locking failure of the bolts on the inner tower components, causing gaps between the inner tower components and the scrubber, and reducing the washing effect.
[0006] To achieve the above object, this application provides the following technical solution: A self-locking inner tower component pressing device includes a tower body, a component to be pressed provided inside the tower body, and a locking structure provided inside the tower body for fixing the component to be pressed on the tower body.
[0007] Different from the existing pressing devices inside the tower: The locking structure includes a large-diameter pipe, small-diameter pipes fixedly installed at both ends of the large-diameter pipe, and a fixed sleeve sleeved on the small-diameter pipes and connected to the tower body; wherein, the axis of the large-diameter pipe and the axis of the small-diameter pipe are not on the same straight line; wherein, bolts for locking the small-diameter pipes on the fixed sleeve and nuts threadedly engaged with the bolts are provided on the fixed sleeve. During use, first, the piece to be pressed is installed inside the tower body, then the large-diameter pipe is held by hand, and then the small-diameter pipes at both ends of the large-diameter pipe are inserted into the fixed sleeve. Then, the large-diameter pipe is rotated so that the side of the large-diameter pipe away from the small-diameter pipe contacts the piece to be pressed, and then the piece to be pressed is squeezed to fix the position of the piece to be pressed. Then, the small-diameter pipes are locked on the fixed sleeve through the cooperation of the bolts and the nuts, and the positions of the small-diameter pipes and the large-diameter pipe are locked, so as to avoid the phenomenon that the large-diameter pipe rotates around the contact part of the small-diameter pipe and the fixed sleeve due to the vibration of the piece to be pressed during use, resulting in the failure of the large-diameter pipe to lock the piece to be pressed. This application uses a locking structure that combines a small-diameter pipe group with an eccentric pressing pipe fixedly connected to the side of the end of the large-diameter pipe and then cooperates with the fixed sleeve to lock the piece to be pressed, replacing the traditional method of using bolts to fix the piece to be pressed, with the characteristics of firm fixation, simple structure, and convenient operation. During installation, the small-diameter pipes are inserted into the fixed sleeve, and at the same time, the small-diameter pipes are located below the large-diameter pipe. During locking, the small-diameter pipes are located above the large-diameter pipe, and the large-diameter pipe contacts the piece to be pressed. The small-diameter pipes are locked on the fixed sleeve through the cooperation of the bolts and the nuts, and the positions of the small-diameter pipes and the large-diameter pipe are locked, so as to avoid the phenomenon that the large-diameter pipe rotates around the contact part of the small-diameter pipe and the fixed sleeve due to the vibration of the piece to be pressed during use, resulting in the failure of the large-diameter pipe to lock the piece to be pressed.
[0008] Preferably, in order to facilitate the circumferential rotation of the large-diameter pipe: A groove for facilitating the rotation of the large-diameter pipe is provided on the large-diameter pipe. When the large-diameter pipe needs to be rotated, only need to hold the groove and the large-diameter pipe, and then rotate the large-diameter pipe in one direction, which is convenient to operate.
[0009] Preferably, in order to facilitate the connection between the large-diameter pipe and the small-diameter pipe: The large-diameter pipe and the small-diameter pipe are integrally arranged to form an eccentric pressing pipe. When the large-diameter pipe and the small-diameter pipe need to be connected, the large-diameter pipe and the small-diameter pipe are directly integrally processed and formed into an eccentric pressing pipe, avoiding connecting the large-diameter pipe and the small-diameter pipe by welding, reducing the operation process and cost.
[0010] Preferably, in order to improve the service life of the large-diameter pipe, the small-diameter pipe and the fixed sleeve: The large-diameter pipe, the small-diameter pipe and the fixed sleeve are all made of fiberglass material. Since the gas inside the tower body is corrosive, fiberglass has the characteristics of high strength and corrosion resistance. Therefore, using fiberglass to make the large-diameter pipe, the small-diameter pipe and the fixed sleeve can improve the service life of the large-diameter pipe, the small-diameter pipe and the fixed sleeve.
[0011] Preferably, in order to improve the stability of the large-diameter pipe in locking the component to be clamped: the inner diameter of the fixed sleeve is the same as the outer diameter of the small-diameter pipe. By ensuring that the inner wall of the fixed sleeve is in contact with the outer wall of the small-diameter pipe, it can be guaranteed that during the rotation of the large-diameter pipe, the outer wall of the small-diameter pipe and the inner wall of the fixed sleeve always remain in contact, avoiding the phenomenon that due to the vibration of the component to be clamped, the axis of the small-diameter pipe and the axis of the fixed sleeve are not on the same straight line, resulting in the rotation of the large-diameter pipe and the failure of locking the component to be clamped.
[0012] Preferably, in order to reduce the rotational flexibility of the small-diameter pipe inside the fixed sleeve: both the inner wall of the fixed sleeve and the outer wall of the small-diameter pipe are rough surfaces. By machining and polishing the inner wall of the fixed sleeve and the outer wall of the small-diameter pipe into rough surfaces, the friction between the fixed sleeve and the small-diameter pipe can be increased, and thus a certain restriction can be imposed on the circumferential rotation of the large-diameter pipe.
[0013] Preferably, in order to facilitate the connection between the small-diameter pipe and the fixed sleeve: two-thirds of the arc pipes of both the small-diameter pipe and the fixed sleeve are cut off, leaving one-third of the arc pipe, and the opening of the one-third of the arc pipe of the fixed sleeve faces the component to be clamped. During use, the one-third of the small-diameter pipe can be directly placed below the one-third of the fixed sleeve, improving the adaptability between the small-diameter pipe and the fixed sleeve.
[0014] Preferably, in order to facilitate the installation, disassembly and replacement of the bolt: through holes for inserting the bolt are provided on both the fixed sleeve and the small-diameter pipe. During installation, only need to pass the bolt through the through hole and then screw the nut on the bolt, which is simple and convenient to operate.
[0015] This application uses a locking structure for locking the component to be clamped by fixedly connecting a small-diameter pipe group offset-axis compression pipe to the side of the end of the large-diameter pipe and then cooperating with a fixed sleeve, replacing the traditional method of using bolts to fix the component to be clamped. It has the characteristics of firm fixation, simple structure and convenient operation. During installation, the small-diameter pipe is inserted into the fixed sleeve, and at the same time, the small-diameter pipe is located below the large-diameter pipe. During locking, the small-diameter pipe is located above the large-diameter pipe, and the large-diameter pipe is in contact with the component to be clamped. The small-diameter pipe is locked on the fixed sleeve through the cooperation of the bolt and the nut, locking the positions of the small-diameter pipe and the large-diameter pipe, and avoiding the phenomenon that during use, due to the vibration of the component to be clamped, the large-diameter pipe rotates around the contact part of the small-diameter pipe and the fixed sleeve, resulting in the failure of locking the large-diameter pipe to the component to be clamped.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0022] Embodiment 1
[0023] This embodiment provides a self-locking tower internals clamping device, as Figures 1-3As shown in the figure, the pressing device includes a tower body 1, a component 2 to be pressed disposed inside the tower body 1, and a locking structure 3 disposed inside the tower body 1 for fixing the component 2 to be pressed on the tower body 1. The locking structure 3 includes a large-diameter pipe 31, small-diameter pipes 32 fixedly installed at both ends of the large-diameter pipe 31, and a fixed sleeve 33 sleeved on the small-diameter pipes 32 and connected to the tower body 1; wherein, the axis of the large-diameter pipe 31 and the axis of the small-diameter pipe 32 are not on the same straight line; wherein, the fixed sleeve 33 is provided with a bolt 34 for locking the small-diameter pipe 32 on the fixed sleeve 33 and a nut 341 threadedly engaged with the bolt 34. During use, first, the component 2 to be pressed is installed inside the tower body 1, then the large-diameter pipe 31 is held by hand, then the small-diameter pipes 32 at both ends of the large-diameter pipe 31 are inserted into the fixed sleeve 33, and then the large-diameter pipe 31 is rotated to make the side of the large-diameter pipe 31 away from the small-diameter pipe 32 contact the component 2 to be pressed, and then the component 2 to be pressed is squeezed to fix the position of the component 2 to be pressed. Then, the small-diameter pipe 32 is locked on the fixed sleeve 33 through the cooperation of the bolt 34 and the nut 341, and the positions of the small-diameter pipe 32 and the large-diameter pipe 31 are locked, so as to avoid the phenomenon that the large-diameter pipe 31 rotates around the contact part of the small-diameter pipe 32 and the fixed sleeve 33 due to the vibration of the component 2 to be pressed during use, resulting in the failure of the large-diameter pipe 31 to lock the component 2 to be pressed. This application uses a locking structure for locking the component 2 to be pressed by fixedly connecting a group of offset-axis pressure pipes of small-diameter pipes 32 to the side of the end of the large-diameter pipe 31 and then cooperating with the fixed sleeve 33, replacing the traditional method of using bolts 34 to fix the component 2 to be pressed, which has the characteristics of firm fixation, simple structure, and convenient operation. During installation, the small-diameter pipe 32 is inserted into the fixed sleeve 33, and at the same time, the small-diameter pipe 32 is located below the large-diameter pipe 31. During locking, the small-diameter pipe 32 is located above the large-diameter pipe 31, and the large-diameter pipe 31 contacts the component 2 to be pressed. The small-diameter pipe 32 is locked on the fixed sleeve 33 through the cooperation of the bolt 34 and the nut 341, and the positions of the small-diameter pipe 32 and the large-diameter pipe 31 are locked, so as to avoid the phenomenon that the large-diameter pipe 31 rotates around the contact part of the small-diameter pipe 32 and the fixed sleeve 33 due to the vibration of the component 2 to be pressed during use, resulting in the failure of the large-diameter pipe 31 to lock the component 2 to be pressed.
[0024] Specifically, a groove 311 is provided on the large-diameter pipe 31 for facilitating the rotation of the large-diameter pipe 31. When it is necessary to rotate the large-diameter pipe 31, only need to hold the groove 311 and the large-diameter pipe 31, and then rotate the large-diameter pipe 31 in one direction, which is convenient to operate.
[0025] Specifically, the large-diameter pipe 31 and the small-diameter pipe 32 are integrally arranged to form an offset-axis pressure pipe. When it is necessary to connect the large-diameter pipe 31 and the small-diameter pipe 32, the large-diameter pipe 31 and the small-diameter pipe 32 are directly integrally processed and formed into an offset-axis pressure pipe, avoiding connecting the large-diameter pipe 31 and the small-diameter pipe 32 by welding, reducing the operation process and cost.
[0026] Specifically, the large-diameter pipe 31, the small-diameter pipe 32 and the fixed sleeve 33 are all made of fiberglass material. Since the gas inside the tower body 1 is corrosive and fiberglass has the characteristics of high strength and corrosion resistance, using fiberglass to make the large-diameter pipe 31, the small-diameter pipe 32 and the fixed sleeve 33 can improve the service life of the large-diameter pipe 31, the small-diameter pipe 32 and the fixed sleeve 33.
[0027] Specifically, the inner diameter of the fixed sleeve 33 is the same as the outer diameter of the small-diameter pipe 32. By the inner wall of the fixed sleeve 33 being in contact with the outer wall of the small-diameter pipe 32, it can be ensured that during the rotation of the large-diameter pipe 31, the outer wall of the small-diameter pipe 32 and the inner wall of the fixed sleeve 33 always remain in contact, avoiding the phenomenon that due to the vibration of the to-be-clamped part 2, the axis of the small-diameter pipe 32 and the axis of the fixed sleeve 33 are not on the same straight line, resulting in the rotation of the large-diameter pipe 31 and the failure of locking the to-be-clamped part 2.
[0028] More specifically, both the inner wall of the fixed sleeve 33 and the outer wall of the small-diameter pipe 32 are rough surfaces. By machining and grinding the inner wall of the fixed sleeve 33 and the outer wall of the small-diameter pipe 32 into rough surfaces, the friction between the fixed sleeve 33 and the small-diameter pipe 32 can be improved, and thus it can play a certain role in restricting the circumferential rotation of the large-diameter pipe 31.
[0029] Specifically, through holes 35 for inserting bolts 34 are provided on both the fixed sleeve 33 and the small-diameter pipe 32. During installation, only need to pass the bolt 34 through the through hole 35 and then screw the nut 341 onto the bolt 34, and the operation is simple and convenient.
[0030] Embodiment 2
[0031] Different from Embodiment 1, (in the case of extrusion deformation at the port of the fixed sleeve 33, there will be a situation where the small-diameter pipe 32 cannot be inserted into the inside of the fixed sleeve 33), for this reason, both the small-diameter pipe 32 and the fixed sleeve 33 cut off two-thirds of the circular pipe and retain one-third of the circular pipe, and the opening of the one-third of the circular pipe retained by the fixed sleeve 33 faces the to-be-clamped part 2. During use, just place the one-third of the small-diameter pipe 32 directly below the one-third of the fixed sleeve 33, which improves the adaptability between the small-diameter pipe 32 and the fixed sleeve 33; during use, when the opening of the small-diameter pipe 32 is opposite to the opening of the fixed sleeve 33 and the small-diameter pipe 32 is located below the large-diameter pipe 31, at this time the large-diameter pipe 31 does not have the locking function for the to-be-clamped part 2; when the opening of the small-diameter pipe 32 is the same as the opening of the fixed sleeve 33 and the small-diameter pipe 32 is located above the large-diameter pipe 31, at this time the large-diameter pipe 31 has the locking function for the to-be-clamped part 2.
[0032] As described above, it is only the preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application should cover within the protection scope of the present application according to the technical solution and its concept of the present application by making equivalent replacements or changes.
