Description

Technical Field

[0001] This utility model relates to the field of tubular reactor cleaning technology, and in particular to an integrated sponge plug and spray device. Background Technology

[0002] Tubular reactors are a common type of chemical reactor. Reactants typically flow in the inner tubes, while cooling or heating media flow in the outer shell, thereby achieving heat exchange and chemical reactions. Currently, dust can easily adhere to the inner tube walls of tubular reactors, affecting heat exchange efficiency and thus impacting performance. Therefore, regular dust removal of the inner tube walls is necessary.

[0003] Currently, due to the different diameters of the multiple inner tubes in a tubular reactor, the cleaning work is mainly carried out manually by inserting a wiping rod into the inner tube to close off the dust. Since there are many inner tubes in a tubular reactor and the inner tube diameters are different, manual cleaning is not only labor-intensive, but also requires frequent replacement of wiping rods of the corresponding size, which makes the cleaning work more complicated and difficult to meet the needs of convenient and efficient cleaning of the inner tube walls of a tubular reactor.

[0004] To solve the above-mentioned technical problems, a sponge plugging and dispensing integrated device is proposed. Utility Model Content

Detailed Implementation

[0030] 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.

[0031] This utility model provides, for example Figures 1-4The sponge inserting and dispensing integrated device shown includes a sponge pneumatic transmission mechanism 100 and a sponge diameter-adjusting transmission mechanism 200. The sponge pneumatic transmission mechanism 100 provides power for the movement of the sponge, and the sponge diameter-adjusting transmission mechanism 200 is located on one side of the sponge pneumatic transmission mechanism 100 and is used to adjust the diameter of the sponge when it enters the inner tube. The device works by feeding the sponge into the sponge pneumatic transmission mechanism 100 and supplying compressed gas into the sponge pneumatic transmission mechanism 100 from an external air source as the power source to drive the sponge's movement, in conjunction with the sponge pneumatic... The transmission mechanism 100 provides a channel for the movement of the sponge, which can satisfy the pneumatic drive for the movement of the sponge. After the sponge is pneumatically driven into the sponge diameter-changing transmission mechanism 200, the sponge diameter-changing transmission mechanism 200 compresses and deforms the sponge block through a squeezing adjustment method, so that the size of the sponge diameter-changing transmission mechanism 200 meets the size of the inner tube of the tubular reactor. In this way, the sponge can enter the inner tube of the tubular reactor through the sponge diameter-changing transmission mechanism 200 for dust cleaning, making the dust cleaning work on the inner wall of the inner tube of the tubular reactor more convenient and efficient.

[0032] The sponge pneumatic transmission mechanism 100 includes an air delivery housing 101, which is a hollow structure with both ends connected. The air delivery housing 101 has a channel for the sponge to move inside, and the inner wall of the channel has a smooth coating to facilitate the transport of the sponge inside the air delivery housing 101. One end of the air delivery housing 101 is provided with an air supply structure, and the end of the air delivery housing 101 near the air supply structure is provided with a feeding structure for the sponge to enter the interior of the air delivery housing 101. A support frame 102 is fixedly installed at the bottom of the air delivery housing 101 and is used to support the air delivery housing 101. An external air source, such as an air compressor, is connected to an air source connector 103 through a hose, so that compressed air can enter the interior of the air delivery housing 101 from the air source connector 103. The sponge is driven to move inside the air delivery housing 101 by the thrust provided by the compressed gas, so that the sponge enters the sponge diameter conversion transmission mechanism 200 along the air delivery housing 101.

[0033] The sponge variable diameter transmission mechanism 200 includes a connecting plate 201 and an adjustment component. Multiple variable diameter pipes 202 are arranged in a circular array at positions corresponding to the ports of the air delivery housing 101 on the side of the connecting plate 201. The inner diameter of each variable diameter pipe 202 gradually increases towards the air delivery housing 101, and the ends of the variable diameter pipes 202 are slidably inserted into the ports of the air delivery housing 101. The adjustment component is located between the connecting plate 201 and the support frame 102, and is used to adjust the communication between the variable diameter pipes 202 at different positions on the connecting plate 201 and the air delivery housing 101. By arranging multiple variable diameter pipes 202 in a circular array on the sponge variable diameter transmission mechanism 200, and each variable diameter pipe 202 having a different diameter funnel-shaped channel, ... This system can meet various diameter requirements for sponges. Utilizing the thrust of compressed gas, the sponge enters from the large-diameter port of the reducing pipe 202 and is gradually compressed and moved towards its small-diameter port. The small-diameter port of the reducing pipe 202 is matched with the port of the inner tube of the tubular reactor for insertion and assembly. This allows the reducing pipe 202 to connect with the inner tube of the tubular reactor, thereby transporting the compressed sponge into the inner tube. With the continuous action of the compressed gas, the sponge moves within the inner tube, effectively wiping and cleaning the dust on its inner wall. An O-ring can be added to the end of the reducing pipe 202 that is inserted into the inner tube of the tubular reactor to increase the sealing of the connection and prevent gas leakage.

[0034] The adjustment assembly includes a connecting shaft 205, an internal gear ring 206, and an external gear ring 207. The connecting shaft 205 is rotatably connected to the side of the support frame 102 near the connecting plate 201. One end of the connecting shaft 205 moves through the side of the connecting plate 201 away from the support frame 102 and is fixedly connected to a limiting end cap 203. An elastic compression spring 204 is sleeved on the outside of the connecting shaft 205 and located between the limiting end cap 203 and the connecting plate 201. The internal gear ring 206 is sleeved on the outside of the connecting shaft 205 and is connected to the side of the support frame 102. The outer toothed ring 207 is sleeved on the outside of the connecting shaft 205 and fixedly connected to the side of the connecting plate 201 near the support frame 102. The outer peripheral wall of the outer toothed ring 207 is slidably inserted into the inner peripheral wall of the inner toothed ring 206. When it is necessary to adjust the position of the variable diameter pipe 202 on the connecting plate 201 to be aligned with the port position of the air delivery housing 101, the connecting plate 201 can be pushed to move away from the air delivery housing 101, compressing the elastic spring 204, thereby separating the outer toothed ring 207 from the inner toothed ring 206. At this time, the connecting plate... The connecting plate 201 can be rotated to adjust the position of the reducing pipe 202 aligned with the port of the air delivery housing 101. After adjustment by rotation, simply move the connecting plate 201 closer to the air delivery housing 101 so that the outer toothed ring 207 and the inner toothed ring 206 are engaged. This stops the radial rotation of the connecting plate 201, ensuring the stability of the reducing pipe 202's connection with the port of the air delivery housing 101, and ensuring the port of the reducing pipe 202 is aligned with the air delivery housing 101. The ports of the delivery housing 101 can be spliced ​​by plugging them together. At the same time, a seal needs to be installed between the two ports to enhance the airtightness after splicing and prevent compressed gas leakage. In other embodiments, in order to prevent gas pressure from pushing the connecting plate 201 away from the gas delivery housing 101, the splicing between the variable diameter pipe 202 and the port of the gas delivery housing 101 can be made by interference fit. Furthermore, an axial blocking structure can be installed between the support frame 102 and the connecting plate 201 to limit the axial movement of the connecting plate 201.

[0035] The air supply structure includes an air source pipe 103, which is fixedly connected to one end of the air delivery housing 101 away from the sponge diameter conversion transmission mechanism 200. The air delivery housing 101 is connected to an external air source through the air source pipe 103. The air source pipe 103 enables the connection between the air delivery housing 101 and the external air source, facilitating the supply of compressed gas to the interior of the air delivery housing 101 by the external air source, thereby providing conveying power for the sponge.

[0036] The feeding structure includes a sponge inlet 104 and an inlet end cap 105. The sponge inlet 104 is fixedly connected to the outer end of the pneumatic conveying housing 101 and communicates with the interior of the pneumatic conveying housing 101. The inlet end cap 105 is detachably connected to the port of the sponge inlet 104 away from the pneumatic conveying housing 101 and is used to seal the port of the sponge inlet 104. The inlet end cap 105 and the sponge inlet 104 can be detachably fixed with screws. The sponge can be fed into the pneumatic conveying housing 101 by feeding the sponge from the port of the sponge inlet 104. The sponge is preferably cylindrical and the porosity of the sponge should not be too large to ensure that the compressed gas can push the sponge to move and compress it.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
