Description

Technical Field

[0001] This utility model relates to the field of pipeline connection equipment technology, and in particular to an extraction tank pipeline connection device. Background Technology

[0002] An extraction tank is an industrial device that achieves liquid-liquid extraction through mechanical stirring and gravity separation. It is mainly used to transfer substances between two or more immiscible solutions. Its core structure consists of a mixing chamber and a clarification chamber. In chemical production processes, the extraction tank is a key piece of equipment for extraction operations, and its connection with various pipelines plays an important role in transporting materials.

[0003] For example, Chinese patent CN220320489U discloses a pipeline connection structure for a centrifugal extractor, including a main body, a connecting pipe and an outer weighing pipe on the main body, a rotating and clamping plate on the outer weighing pipe via a screw, a pipe sleeve on the outside of the connecting pipe, sliding blocks on the front and rear outer walls of the main body via sliding grooves, mounting plates on the sliding blocks, an outer shell on the outside of the main body, and several fixing blocks evenly arranged on the outer shell, threaded holes through the fixing blocks, and fixing bolts connected by threads in the threaded holes.

[0004] Existing extraction tank pipeline connections mostly use traditional methods such as flange connections or threaded connections. However, flange connections or threaded connections have the problem of unstable sealing performance. During long-term use, the sealing gaskets are prone to aging and damage due to factors such as material pressure fluctuations and temperature changes, which can lead to material leakage. This not only causes material waste but may also cause safety accidents and environmental pollution. At the same time, installation and disassembly are difficult, increasing maintenance difficulty and costs, and seriously affecting production efficiency. To address the above problems, an extraction tank pipeline connection device is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, and to propose an extraction tank pipeline connection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an extraction tank pipe connection device, comprising an upper connection assembly and a lower connection assembly. The upper connection assembly includes a top plate and an upper connecting pipe. The bottom end of the upper connecting pipe extends through the top plate to its bottom. Two upper connecting plates are symmetrically fixedly installed at both ends of the bottom of the top plate. The lower connection assembly includes a bottom plate and a lower connecting pipe. The top end of the lower connecting pipe extends through the bottom plate to its top. Through holes are symmetrically opened at both ends of the top of the bottom plate, and vertical plates are symmetrically installed at both ends of the bottom of the bottom plate. A rotating rod is rotatably connected to one end of the front side of the vertical plate. The outer edge of the rotating rod is fixedly connected to the lower connecting plate. The bottom end of the upper connecting plate passes through the through hole and engages with one end of the lower connecting plate. A fixing ring is fixedly connected to the outer edge of the contacting ends of the upper and lower connecting pipes. A retaining ring is fixedly connected to the outer edge of both retaining rings. A rubber ring is slidably connected to the inner side of the retaining ring. Multiple sealing springs are arranged in a ring array between the rubber ring and the fixing ring.

[0007] Preferably, an expansion rubber pad is provided on the side where the two rubber rings are in contact, and an extension rod is fixedly connected to the other end of the front side of the vertical plate.

[0008] Preferably, a baffle is welded to the front side of the vertical plate, a return spring is sleeved on the outer side of the extension rod, and a movable plate is fixedly connected to the bottom of the rotating rod.

[0009] Preferably, one end of the return spring extends outward and fits against the baffle, and the other end of the return spring extends outward and fits against the movable plate.

[0010] Preferably, a fixing plate is fixedly connected to the top of the upper connecting plate, and both ends of the fixing plate are fixedly installed to the top plate.

[0011] Preferably, the bottom plate has symmetrically welded insert blocks at both ends of the top, and the top plate has symmetrically welded insert rods at both ends of the bottom, with the bottom ends of the insert rods being inserted into the insert blocks.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up an upper connecting component and a lower connecting component, when it is necessary to connect the upper and lower pipes, the movable plate is rotated, so that the lower connecting plates on the left and right sides are deflected to the side of the lower connecting pipe. After the bottom of the upper connecting pipe contacts and aligns with the top of the lower connecting pipe, the insert rod and the insert block are inserted. The movable plate is released, and the movable plate and the lower connecting plate automatically rotate back to their original positions under the action of the return spring, realizing the snap-fit ​​between the lower connecting plate and the upper connecting plate. By combining the snap-fit ​​method of the lower connecting plate and the upper connecting plate and the insertion method of the insert rod and the insert block, the connection between the upper connecting pipe and the lower connecting pipe is quickly completed, thereby completing the connection between the extraction tank pipes, solving the problem of difficult installation and disassembly, and reducing the difficulty and cost of maintenance.

[0014] 2. In this utility model, when the upper connecting pipe and the lower connecting pipe are connected, the upper and lower rubber rings are tightly squeezed together under the action of multiple sealing springs. At the same time, the expansion rubber pad that contacts the upper and lower rubber rings expands in volume when it comes into contact with water, which enhances the sealing effect. The tight fit between the rubber rings and the expansion rubber pad can effectively cope with material pressure fluctuations and temperature changes, greatly improve the sealing performance of the connecting device, and prevent material leakage.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4As shown, this utility model provides an extraction tank pipe connection device, including an upper connection component 1 and a lower connection component 2. The upper connection component 1 includes a top plate 11 and an upper connection pipe 13. The bottom end of the upper connection pipe 13 extends through the top plate 11 to its bottom. Two upper connection plates 14 are symmetrically fixedly installed at both ends of the bottom of the top plate 11. The lower connection component 2 includes a bottom plate 21 and a lower connection pipe 22. The top end of the lower connection pipe 22 extends through the bottom plate 21 to its top. A fixing ring 3 is fixedly connected to the outer edge of the contacting end of the upper connection pipe 13 and the lower connection pipe 22. A retaining ring 4 is fixedly connected to the outer edge of the two fixing rings 3. A rubber ring 5 is slidably connected to the inner side of the retaining ring 4. Multiple sealing springs 7 are arranged in a ring array between the rubber ring 5 and the fixing ring 3. An expansion rubber pad 6 is provided on the contacting side of the two rubber rings 5.

[0023] The specific settings and functions of this embodiment are described in detail below: By adding a retaining ring 4, a rubber ring 5, and an expansion rubber pad 6 at the outer edge of the end where the upper connecting pipe 13 and the lower connecting pipe 22 contact each other, when the upper connecting pipe 13 and the lower connecting pipe 22 are connected, the upper and lower rubber rings 5 ​​contact each other and are tightly squeezed together by multiple sealing springs 7. At the same time, an expansion rubber pad 6 is provided around the contact area between the upper and lower rubber rings 5. The expansion rubber pad 6 is made by adding water-absorbing resin (such as sodium polyacrylate or starch derivative) to the rubber, so that it expands in volume when it comes into contact with water, forming a tight watertight barrier and enhancing the sealing effect. The tight fit between the rubber ring 5 and the expansion rubber pad 6 can effectively cope with material pressure fluctuations and temperature changes, greatly improving the sealing performance of the connecting device and preventing material leakage.

[0024] Example 2: Figures 1-3 As shown, the top two ends of the base plate 21 are symmetrically provided with through holes 24, and the bottom two ends of the base plate 21 are symmetrically installed with vertical plates 25. A rotating rod 28 is rotatably connected to one end of the front side of the vertical plate 25. A lower connecting plate 210 is fixedly connected to the outer edge of the rotating rod 28. The bottom end of the upper connecting plate 14 passes through the through hole 24 and is engaged with one end of the lower connecting plate 210. An extension rod 26 is fixedly connected to the other end of the front side of the vertical plate 25. A baffle 29 is welded to the front side of the vertical plate 25. A return spring 2 is sleeved on the outer side of the extension rod 26. 7. A movable plate 211 is fixedly connected to the bottom of the rotating rod 28. One end of the return spring 27 extends outward and fits against the baffle 29, and the other end of the return spring 27 extends outward and fits against the movable plate 211. A fixed plate 12 is fixedly connected to the top of the upper connecting plate 14, and both ends of the fixed plate 12 are fixedly installed with the top plate 11. Insert blocks 23 are symmetrically welded to the top two ends of the bottom plate 21, and insert rods 15 are symmetrically welded to the bottom two ends of the top plate 11, and the bottom end of the insert rod 15 is inserted into the insert block 23.

[0025] The overall effect of this embodiment is that the connecting device consists of an upper connecting component 1 and a lower connecting component 2. The top end of the upper connecting pipe 13 of the upper connecting component 1 is connected to one of the pipes in the extraction tank, and the bottom end of the lower connecting pipe 22 of the lower connecting component 2 is connected to the other end of the pipe in the extraction tank. When it is necessary to connect the upper and lower pipes, it is only necessary to connect the upper connecting pipe 13 and the lower connecting pipe 22. The upper connecting pipe 13 is placed at the top of the lower connecting pipe 22, and the movable plate 211 and the rotating rod 28 are manually rotated (e.g., Figure 3 As shown, rotate the left rotating rod 28 clockwise and the right rotating rod 28 counterclockwise, thereby causing the lower connecting plates 210 on both sides to deflect towards the lower connecting tube 22. At this time, the movable plate 211 presses the return spring 27, moving the upper connecting assembly 1 downward until the bottom of the upper connecting tube 13 contacts and aligns with the top of the lower connecting tube 22. Then, the bottom end of the upper connecting plate 14 extends through the through hole 24 to the front of the vertical plate 25, and at the same time, the insertion rod 15 is inserted into the insertion block 23. At this time, release the movable plate 211, and the return spring 27 returns to its original state. The movable plate 211 and the lower connecting plate 210 automatically rotate back to their original positions under the action of the return spring 27, realizing the engagement of the lower connecting plate 210 and the upper connecting plate 14 (as shown). Figure 3 As shown, by combining the snap-fit ​​connection between the lower connecting plate 210 and the upper connecting plate 14, and the insertion connection between the insert rod 15 and the insert block 23, the connection between the upper connecting pipe 13 and the lower connecting pipe 22 can be quickly completed, thereby completing the connection between the extraction tank pipes, solving the problem of difficult installation and disassembly, and reducing maintenance difficulty and maintenance costs.

[0026] The usage and working principle of this device are as follows: When it is necessary to connect the upper and lower pipes, place the upper connecting pipe 13 at the top of the lower connecting pipe 22, manually rotate the movable plate 211 and the rotating rod 28, so that the lower connecting plates 210 on both sides deflect to the lower connecting pipe 22. At this time, after the bottom of the upper connecting pipe 13 contacts and aligns with the top of the lower connecting pipe 22, the insertion rod 15 is inserted into the insertion block 23. Release the movable plate 211, and the movable plate 211 and the lower connecting plate 210 will automatically rotate back to their original positions under the action of the return spring 27, realizing the snap-fit ​​between the lower connecting plate 210 and the upper connecting plate 14. By combining the snap-fit ​​method between the lower connecting plate 210 and the upper connecting plate 14 and the insertion method between the insertion rod 15 and the insertion block 23, the connection between the upper connecting pipe 13 and the lower connecting pipe 22 can be quickly completed.

[0027] Meanwhile, by adding a retaining ring 4, a rubber ring 5, and an expansion rubber pad 6 at the outer edge of the end where the upper connecting pipe 13 and the lower connecting pipe 22 contact each other, when the upper connecting pipe 13 and the lower connecting pipe 22 are connected, the upper and lower rubber rings 5 ​​contact each other and are tightly squeezed together by multiple sealing springs 7. At the same time, an expansion rubber pad 6 is provided around the contact area of ​​the upper and lower rubber rings 5. The expansion rubber pad 6 expands in volume when it comes into contact with water. The tight fit between the rubber ring 5 and the expansion rubber pad 6 improves the sealing performance of the connecting device and prevents material leakage.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
