Description

Technical Field

[0001] This utility model relates to the field of dry sealing joint technology, and in particular to a dry sealing joint for fluid loading and unloading with self-cleaning function. Background Technology

[0002] Fluid loading and unloading refers to the operation of loading and unloading liquids or gases. It is usually carried out in places such as ports, docks, oil fields, and chemical plants. In the process of loading and unloading fluids, dry sealing joints are required to prevent leakage of fluids during the loading and unloading process, thereby improving the safety of their use.

[0003] In the high-sealing dry connector with announcement number CN220102385U, belonging to the field of dry connector technology, it addresses the problem that the connection between the dry connector and the external connection structure is usually directly snapped together, which makes the connection easy to loosen, resulting in poor sealing effect at the connection between the dry connector and the connection structure. The connector body includes a connection groove at one end. This utility model achieves a stable snap-fit ​​connection between the outer wall of the sealing gasket and the inner wall of the connection groove through the mutual installation and cooperation of the sealing gasket and the block, so as to achieve a high-seal seal between the inner wall of the connector body and the external connection structure, so as to have efficient sealing when the device is connected to the external connection structure. Through the mutual installation and cooperation of the sliding plate and the limiting post, one side of the sliding plate is tightly connected to the rubber plate, so that the inner wall of the rubber plate is stably snapped to the outer wall of the connector body, thereby strengthening the stability of the connection between the device and the external connection structure.

[0004] However, existing high-sealing dry joints still have the following drawbacks in use: The existing technology relies on the mutual installation and cooperation of the sliding plate and the limiting post to achieve a tight connection between one side of the sliding plate and the rubber plate, so that the inner wall of the rubber plate is stably locked with the outer wall of the joint body, thereby realizing the loading and unloading of fluid. However, in actual use, the above operation does not have a self-cleaning function, making it inconvenient to clean the fluid remaining inside the joint body. This not only causes corrosion to the joint body, affecting its service life, but also pollutes subsequent fluid loading and unloading, thus failing to ensure the quality of fluid loading and unloading. Utility Model Content

[0005] The purpose of this utility model is to provide a dry sealing joint for fluid loading and unloading with a self-cleaning function, so as to solve the problem mentioned in the background art that the existing dry sealing joints for fluid loading and unloading do not have a self-cleaning function during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dry sealing joint for fluid loading and unloading with self-cleaning function, comprising a dry joint body, a fixed baffle, and a fixed rubber plate, wherein the fixed rubber plate is slidably engaged on one side of the dry joint body, and the fixed baffle is fixed inside the dry joint body;

[0007] An annular sealing gasket is provided on one side of the fixed baffle, and a sealing mechanism is provided on one side of the annular sealing gasket. A cleaning mechanism is provided inside the dry connector body on one side of the fixed baffle.

[0008] Furthermore, the cleaning mechanism includes an annular fixing tube, which is disposed inside the dry connector body. A connecting pipe is fixedly connected to one side of the front of the annular fixing tube. Fixed nozzles are uniformly fixed to one side of the annular fixing tube, and a sealing baffle is slidably disposed on one side of the fixed nozzle. Two guide rods are fixed to one side of the sealing baffle, and a fixing block is disposed on the outer side of each guide rod. One side of the fixing block is fixedly connected to the inner wall of the fixed nozzle. A slider is fixed to one end of the guide rod, and a return spring is fixed to one side of the slider. The return spring is uniformly wound around the outer side of the guide rod.

[0009] Furthermore, multiple sealing baffles are provided, each with a circular cross-section, and the multiple sealing baffles are arranged in a ring shape.

[0010] Furthermore, two reset springs are provided, both of which are made of stainless steel, and the outer sides of both reset springs are uniformly coated with a corrosion-resistant coating.

[0011] Furthermore, two guide rods are provided, both of which slide inside the fixed block, and the sealing baffle is slidably connected to the fixed nozzle through the guide rods and the fixed block.

[0012] Furthermore, the sealing mechanism includes an annular support plate, which is disposed on one side of the annular sealing gasket. Two annular protrusions are fixed on one side of the annular support plate, and a sealing groove is provided on the outer side of the annular protrusions, which is opened inside the fixed rubber plate.

[0013] Furthermore, there are two annular protrusions, which are symmetrically distributed and are both made of rubber.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the self-cleaning dry sealing joint for fluid loading and unloading not only has a self-cleaning function, but also improves the sealing effect;

[0015] 1. Connect an external air blowing device through a connecting pipe to introduce clean airflow into the annular fixed pipe and then into the fixed nozzle. The high-pressure airflow overcomes the force of the return spring and blows the sealing baffle horizontally. When one side of the sealing baffle moves away from the fixed nozzle, the fixed nozzle opens, making it easier to introduce airflow into the dry connector body. The above operation cleans the inside of the dry connector body, which not only prevents residual fluid from corroding the dry connector body and affecting its service life, but also prevents contamination of subsequent fluid loading and unloading, thus ensuring the quality of fluid loading and unloading and improving its practicality.

[0016] After cleaning, the force of the compression on the return spring disappears, which pushes the slider to move horizontally. Under the action of the guide rod, the sealing baffle moves horizontally, so that the sealing baffle and the fixed nozzle fit together. The above operation makes it easy to close the fixed nozzle, thereby sealing the fixed nozzle to avoid leakage during fluid loading and unloading.

[0017] 2. The annular support plate is inserted into the sealing groove, which compresses the annular protrusion. When pushed into place, the annular protrusion recovers its deformation, thereby generating huge contact stress in all directions, tightly filling the micro gaps in the sealing groove, and improving the sealing effect during use with the cooperation of the annular sealing gasket.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Please see Figures 1-6 The present invention provides the following technical solution:

[0028] Example 1: To address the problem of poor sealing performance in the prior art, the following technical solution is disclosed. Please refer to the following for details. Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, a dry-type sealing connector for fluid loading and unloading with self-cleaning function includes a dry-type connector body 1, a fixed baffle 3, and a fixed rubber plate 6. The fixed rubber plate 6 is slidably snapped onto one side of the dry-type connector body 1. The fixed baffle 3 is fixed inside the dry-type connector body 1. An annular sealing gasket 4 is provided on one side of the fixed baffle 3, and a sealing mechanism 5 is provided on one side of the annular sealing gasket 4. The sealing mechanism 5 includes an annular support plate 501, which is located on one side of the annular sealing gasket 4. Two annular protrusions 503 are fixed on one side of the annular support plate 501. A sealing groove 502 is provided on the outer side of the annular protrusion 503, and the sealing groove 502 is opened inside the fixed rubber plate 6. There are two annular protrusions 503, which are symmetrically distributed, and both annular protrusions 503 are made of rubber.

[0029] In this embodiment, by pushing the annular sealing gasket 4, it enters the interior of the dry connector body 1 and adheres to the fixed baffle 3. During the sliding engagement of the dry connector body 1 and the fixed rubber plate 6, the annular sealing gasket 4 is squeezed, thereby causing the annular support plate 501 to insert into the sealing groove 502. During the continuous pushing of the fixed rubber plate 6, the annular protrusion 503 is deformed by the combined compression of the inner wall of the sealing groove 502 and the annular support plate 501. When the annular support plate 501 and the sealing groove 502 adhere to each other, the squeezing force on the annular protrusion 503 disappears, allowing the annular protrusion 503 to recover its deformation and generate huge contact stress in all directions, tightly filling the micro gaps in the sealing groove 502. This improves the sealing performance of the connection between the dry connector body 1 and the fixed rubber plate 6, and with the cooperation of the annular sealing gasket 4, the sealing effect during use can be further improved, preventing leakage during fluid loading and unloading.

[0030] Example 2 differs from Example 1 in that it also features a self-cleaning function during use. Therefore, the following technical solution is disclosed. Please refer to the details below. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a cleaning mechanism 2 is provided inside the dry connector body 1 on one side of the fixed baffle 3. The cleaning mechanism 2 includes an annular fixed tube 201, which is located inside the dry connector body 1. A connecting pipe 204 is fixedly connected to one side of the annular fixed tube 201. Fixed nozzles 203 are evenly fixed on one side of the annular fixed tube 201, and a sealing baffle 202 is slidably provided on one side of the fixed nozzles 203. Two guide rods 208 are fixed on one side of the sealing baffle 202, and a fixing block 207 is provided on the outer side of each guide rod 208. One side of the fixing block 207 is fixedly connected to the inner wall of the fixed nozzle 203, and one end of the guide rod 208 is fixed. A slider 206 is fixed, and a return spring 205 is fixed on one side of the slider 206. The return spring 205 is evenly wound around the outside of the guide rod 208. Multiple sealing baffles 202 are provided. The cross-section of the multiple sealing baffles 202 is circular, and the multiple sealing baffles 202 are distributed in a ring. Two return springs 205 are provided. Both return springs 205 are made of stainless steel, and the outside of the two return springs 205 are evenly coated with corrosion-resistant coating. Two guide rods 208 are provided. Both guide rods 208 slide inside the fixing block 207. The sealing baffles 202 are slidably connected to the fixed nozzle 203 through the guide rods 208 and the fixing block 207.

[0031] In this embodiment, when the dry connector body 1 is disconnected after fluid loading and unloading, it is connected to an external air blowing device through the connecting pipe 204, thus facilitating the introduction of the blown gas into the interior of the annular fixed pipe 201. The annular fixed pipe 201 evenly introduces the gas into the interior of multiple fixed nozzles 203. When the gas enters the interior of the fixed nozzle 203, it pushes the sealing baffle 202 to move horizontally, thereby causing the guide rod 208 to slide inside the fixed block 207. By providing the guide rod 208, it can limit the movement of the sealing baffle 202 to prevent it from shifting position, and it can also guide the movement of the sealing baffle 202, thereby improving its stability during movement. While the sealing baffle 202 is moving, under the action of the guide rod 208, it drives the slider 206 to squeeze the return spring 205, thereby compressing the return spring 205 under the squeezing force. After the side of 02 is moved away from the fixed nozzle 203, it is easier to open the fixed nozzle 203, thereby facilitating the expulsion of gas that has entered the fixed nozzle 203. This facilitates the cleaning of residual fluid inside the dry connector body 1. After cleaning the dry connector body 1, the connecting pipe 204 is disconnected from the external air blowing equipment, causing the force on the return spring 205 to disappear. This pushes the slider 206 to move horizontally, and under the action of the guide rod 208, the sealing baffle 202 moves horizontally until one side of the sealing baffle 202 and the fixed nozzle 203 are in contact. Through the above operation, the fixed nozzle 203 can be closed, thus preventing fluid from entering the interior of the fixed nozzle 203 during subsequent loading and unloading. Through the above operation, the interior of the dry connector body 1 can be cleaned, which not only prevents residual fluid from corroding the dry connector body 1, but also avoids cross-contamination, thereby improving its practicality.
