Description

Technical Field

[0001] This utility model relates to the field of settling device technology, specifically a settling device for toluenesulfonamide formaldehyde resin with a sealing component. Background Technology

[0002] The toluenesulfonamide formaldehyde resin settling device is used in the production process of toluenesulfonamide formaldehyde resin to allow the reacted materials to settle, separate, precipitate, or age. The main function of the settling device is to allow different phases of substances, such as unreacted raw materials, generated resin, and solvents, to separate naturally under gravity by allowing the materials to settle. This facilitates further processing and purification of the resin phase. During the resin settling process, the chamber is usually sealed to ensure the device operates smoothly. The process is kept in a sealed state to prevent the toluenesulfonamide formaldehyde resin from volatilizing or reacting with the outside air. However, in the existing technology, in addition to sealing between the valve and the discharge pipe, the box body and the cover plate also need to be sealed. However, the sealing ring between the box body and the cover plate is prone to aging, hardening, and cracking due to long-term contact with the toluenesulfonamide formaldehyde resin and the influence of factors such as temperature and pressure, which leads to a decrease in sealing performance. At the same time, in order to ensure the sealing effect, the cover plate and the box body are usually equipped with a relatively complex sealing structure, which makes the loading and unloading process relatively slow, thereby increasing maintenance costs and downtime.

[0003] A toluenesulfonamide formaldehyde resin settling device with a sealing component is proposed to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a toluenesulfonamide formaldehyde resin settling device with a sealing component, in order to solve the problem mentioned in the background art. In the existing technology, in addition to sealing between the valve and the discharge pipe, the box body and the cover plate also need to be sealed. However, the sealing ring between the box body and the cover plate is prone to aging, hardening, and cracking due to long-term contact with toluenesulfonamide formaldehyde resin and the influence of factors such as temperature and pressure, which leads to a decrease in sealing performance. At the same time, in order to ensure the sealing effect, the cover plate and the box body are usually equipped with a relatively complex sealing structure, which makes the loading and unloading process relatively slow, thereby increasing maintenance costs and downtime.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a toluenesulfonamide formaldehyde resin settling device with a sealing component, comprising a fixing frame, wherein a box is connected through the middle of the fixing frame;

[0006] A cover plate is attached to the top surface of the box. A feed pipe is provided on one side of the top surface of the cover plate. Mounting blocks are symmetrically installed on both sides of the cover plate and the box. A threaded rod is connected through the middle of the inside of the mounting block. Nuts are threaded to both sides of the threaded rod.

[0007] Also includes:

[0008] A sealing ring is provided on the bottom surface of the cover plate;

[0009] Among them, several inserts are connected through the surface of the sealing ring;

[0010] The surface of the insertion rod is fitted with a return spring.

[0011] Preferably, one side surface of the return spring is fixedly connected to the sealing ring, and a stabilizing block is fixedly connected to the other side surface of the return spring, and the insertion rod is fixedly connected to the stabilizing block.

[0012] Preferably, a discharge pipe is connected through the middle of the bottom surface of the box, and a valve is fixedly installed inside the discharge pipe.

[0013] Preferably, a stirring assembly is provided on one side surface of the box body near the middle. The stirring assembly includes a drive motor fixedly connected to the box body, and a rotating rod is fixedly connected to the output end of the drive motor through one side surface of the box body.

[0014] Preferably, a plurality of stirring blades are fixedly installed on the surface of the rotating rod, and the rotating rod is rotatably connected to the housing.

[0015] Preferably, the feed pipe is threaded with a sealing cap.

[0016] Preferably, the cover plate has several symmetrical slots inside, which are engaged with the insertion rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this toluenesulfonamide formaldehyde resin settling device with a sealing component, by setting an insertion rod, a return spring, a stabilizing block and a slot, enables quick replacement of sealing rings that have been used for a long time, thereby reducing maintenance costs and downtime to a certain extent. The specific details are as follows:

[0018] 1. By setting up a plug rod, a return spring, a stabilizing block, and a slot, when it is necessary to replace the sealing ring that has been used for a long time, after separating the cover plate from the box, pulling the stabilizing block will cause the stabilizing block to move, which in turn will cause the plug rod to separate from the slot, thus allowing the long-used sealing ring to be removed. When installing the sealing ring, after placing it on the cover plate, loosening the stabilizing block will allow it to return to its original position under the action of the return spring. Simultaneously, when the return spring returns to its original position, it will also cause the plug rod to return to its original position, allowing the plug rod to re-engage with the slot, thus completing the installation of the sealing ring. The return spring can be coated with anti-corrosion paint according to actual production requirements to ensure its service life. The size of the sealing ring is such that its outer wall fits snugly against the inside of the box, ensuring a tight seal between the cover plate and the box.

[0019] 2. By setting up a stirring assembly, after the toluenesulfonamide formaldehyde resin is poured into the tank through the feed pipe, the sealing cap is connected to the feed pipe to form a seal. At the same time, a sealing ring is also set inside the sealing cap to ensure that the feed pipe and the sealing cap can be sealed. After the toluenesulfonamide formaldehyde resin enters the tank, the drive motor is started by the control switch, so that the output end of the drive motor drives the rotating rod to rotate. The rotation of the rotating rod drives the stirring blade to rotate, so that the toluenesulfonamide formaldehyde resin can be appropriately stirred during the initial stage or process of settling. This can promote the uniform mixing and phase separation of the materials, but the stirring speed is much lower than the stirring speed during the reaction stage.

[0020] 3. By using threaded rods and nuts. When cleaning the inside of the enclosure is required, the nuts on both sides of the threaded rod are rotated to separate them from the rod. Pulling the rod then separates it from the mounting block, allowing the cover plate and enclosure to be separated. This makes cleaning the inside of the enclosure much easier. Compared to bolts and screw holes, using threaded rods and nuts simplifies disassembly; simply unscrew the nut and pull out the threaded rod. This is more convenient, and the threaded rod and nut can usually be replaced or repaired separately. If only the nut or threaded rod is faulty, it doesn't require repairing or remachining the entire screw hole as is often the case with bolts and screw holes. This makes disassembly and assembly easier and reduces costs to some extent. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a toluenesulfonamide formaldehyde resin settling device with a sealing component, including a fixing frame 1, with a box 2 penetrating through the middle of the fixing frame 1; a cover plate 3 is attached to the top surface of the box 2, a feed pipe 4 is provided on one side of the top surface of the cover plate 3, mounting blocks 5 are symmetrically installed on both sides of the cover plate 3 and the box 2, a threaded rod 6 is penetrating through the middle of the mounting block 5, and nuts 7 are threadedly connected to both sides of the threaded rod 6; it also includes: a sealing ring 12 is provided on the bottom surface of the cover plate 3; wherein, a plurality of rods 13 are penetrating through the surface of the sealing ring 12; wherein, a return spring 14 is sleeved on the surface of the rod 13, such as Figure 1-5 As shown, by setting the insertion rod 13, the reset spring 14, the stabilizing block 15 and the slot 16, the sealing ring 12 that has been used for a long time can be quickly replaced, thereby reducing maintenance costs and downtime to a certain extent.

[0029] One side surface of the return spring 14 is fixedly connected to the sealing ring 12, and a stabilizing block 15 is fixedly connected to the other side surface of the return spring 14. The insertion rod 13 is fixedly connected to the stabilizing block 15. Figure 3 , 4As shown, by setting up the insertion rod 13, return spring 14, stabilizing block 15, and slot 16, when it is necessary to replace the sealing ring 12 that has been used for a long time, after separating the cover plate 3 from the housing 2, the stabilizing block 15 is pulled, which causes the insertion rod 13 to move. The movement of the insertion rod 13 separates it from the slot 16, thus allowing the long-used sealing ring 12 to be removed. When installing the sealing ring 12, after placing it on the cover plate 3, it is then loosened... The stabilizing block 15 is moved so that it returns to its original position under the action of the return spring 14. At the same time, when the return spring 14 returns to its original position, it can also drive the insertion rod 13 to return to its original position, so that the insertion rod 13 and the slot 16 are re-engaged, thereby completing the installation of the sealing ring 12. Meanwhile, the return spring 14 can be coated with anti-corrosion paint according to actual production requirements, thereby ensuring the service life of the return spring 14. At the same time, the size of the sealing ring 12 is such that the outer wall fits the inside of the box 2, thereby ensuring the sealing between the cover plate 3 and the box 2.

[0030] A discharge pipe 8 is connected through the middle of the bottom surface of the box 2. A valve 9 is fixedly installed inside the discharge pipe 8. Figure 1 As shown, the connection method between valve 9 and feed pipe 8 is the same as that in the prior art, and the sealing method is also the same as that in the prior art.

[0031] A stirring assembly 10 is provided on one side surface of the housing 2 near the middle. The stirring assembly 10 includes a drive motor 1001 fixedly connected to the housing 2. A rotating rod 1002 is fixedly connected to the output end of the drive motor 1001 through one side surface of the housing 2. Several stirring blades 1003 are fixedly installed on the surface of the rotating rod 1002. The rotating rod 1002 is rotatably connected to the housing 2. A sealing cap 11 is threadedly connected to the surface of the feed pipe 4. Figure 2 As shown, by setting the stirring assembly 10, after the toluenesulfonamide formaldehyde resin is poured into the tank 2 through the feed pipe 4, the sealing cover 11 is connected to the feed pipe 4 to form a seal. At the same time, a sealing ring 12 is also set inside the sealing cover 11 to ensure that the feed pipe 4 and the sealing cover 11 can be sealed. After the toluenesulfonamide formaldehyde resin enters the tank 2, the drive motor 1001 is started by the control switch, so that the output end of the drive motor 1001 drives the rotation rod 1002 to rotate. The rotation of the rotation rod 1002 drives the rotation of the stirring blade 1003, so that the toluenesulfonamide formaldehyde resin can be appropriately stirred in the initial stage or during the standing process to promote the uniform mixing and phase separation of the materials. However, the stirring speed is much lower than the stirring speed in the reaction stage.

[0032] The cover plate 3 has several symmetrically arranged slots 16 inside, which engage with the insert rod 13. Figure 5As shown, when installing the sealing ring 12, after placing the sealing ring 12 on the cover plate 3, the stabilizing block 15 is loosened, so that the stabilizing block 15 returns to its original position under the action of the return spring 14. At the same time, when the return spring 14 returns to its original position, it can also drive the insertion rod 13 to return to its original position, so that the insertion rod 13 and the slot 16 are re-engaged together, thereby completing the installation of the sealing ring 12.

[0033] Working principle: Before using this toluenesulfonamide formaldehyde resin settling device with a sealing component, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, by first setting up the insertion rod 13, return spring 14, stabilizing block 15, and slot 16, when it is necessary to replace the sealing ring 12 that has been used for a long time, after separating the cover plate 3 from the housing 2, the stabilizing block 15 is pulled, which causes the insertion rod 13 to move. The movement of the insertion rod 13 separates it from the slot 16, allowing the long-used sealing ring 12 to be removed. Simultaneously, when installing the sealing ring 12, after placing it on the cover plate 3, the... Loosen the stabilizing block 15 so that it returns to its original position under the action of the return spring 14. At the same time, when the return spring 14 returns to its original position, it can also drive the insertion rod 13 to return to its original position, so that the insertion rod 13 and the slot 16 are re-engaged, thereby completing the installation of the sealing ring 12. Meanwhile, the return spring 14 can be coated with anti-corrosion paint according to actual production requirements to ensure the service life of the return spring 14. At the same time, the size of the sealing ring 12 is such that the outer wall fits the inside of the box 2, thereby ensuring the sealing between the cover plate 3 and the box 2.

[0034] Secondly, by setting up the stirring assembly 10, after the toluenesulfonamide formaldehyde resin is poured into the tank 2 through the feed pipe 4, the sealing cover 11 is connected to the feed pipe 4 to form a seal. At the same time, a sealing ring 12 is also set inside the sealing cover 11 to ensure that the feed pipe 4 and the sealing cover 11 can be sealed. After the toluenesulfonamide formaldehyde resin enters the tank 2, the drive motor 1001 is started by the control switch, so that the output end of the drive motor 1001 drives the rotation rod 1002 to rotate. The rotation of the rotation rod 1002 drives the rotation of the stirring blade 1003, so that the toluenesulfonamide formaldehyde resin can be appropriately stirred in the initial stage or during the standing process to promote the uniform mixing and phase separation of the materials. However, the stirring speed is much lower than the stirring speed in the reaction stage.

[0035] Finally, by setting the threaded rod 6 and nut 7, when it is necessary to clean the inside of the box 2, by rotating the nuts 7 on both sides of the threaded rod 6, the nuts 7 are separated from the threaded rod 6. Then, by pulling the threaded rod 6, it is separated from the mounting block 5, thereby separating the cover plate 3 from the box 2. This makes it easier to clean the inside of the box 2. At the same time, by using the threaded rod 6 and nut 7, compared with bolts and screw holes, when disassembling the main body, you only need to unscrew the nut 7 and then pull out the threaded rod 6. Relatively speaking, the operation is simpler and more convenient. Moreover, the threaded rod 6 and nut 7 can usually be replaced or repaired separately. If only the nut 7 or the threaded rod 6 has a problem, it is not necessary to repair or re-machine the entire screw hole as with bolts and screw holes. This makes the disassembly and installation of the main body more convenient and can also reduce the increase in costs to a certain extent.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
