Description

Technical Field

[0001] This utility model relates to the field of extraction tank technology, specifically to a cleaning device for the observation tube of an extraction tank. Background Technology

[0002] After the two immiscible liquids are extracted in the extraction tank, the liquid is discharged through an outlet pipe connected to the bottom of the extraction tank. During the liquid discharge process, in order to know in advance whether there is any turbid liquid mixed with the two immiscible liquids, an observation point is set on the outlet pipe at the bottom of the extraction tank to observe the liquid and take appropriate measures in advance. This observation point includes an observation tube connected to the outlet pipe at the bottom of the extraction tank. After long-term use, some liquid will remain inside the observation tube. This residual liquid will affect the subsequent delivery of other liquids, especially if the observation tube shows that there is a turbid liquid mixed with the immiscible liquids being delivered. In this case, the liquid will be returned to the extraction tank for re-extraction. If other residual liquids are brought back to the extraction tank for extraction, it will affect the final extraction result, and the residual liquid will also affect whether the liquid inside is turbid as observed through the observation tube. Utility Model Content

[0003] This invention addresses the problem of residual liquid remaining in the observation tube connected to the bottom of the extraction tank after the liquid has flowed through, thus affecting the subsequent delivery of other liquids and making it difficult to observe whether turbidity has occurred through the observation tube. It provides a cleaning device for the observation tube of the extraction tank, which can clean the inside of the observation tube and prevent residual liquid from adhering to the inner wall of the observation tube, thus avoiding affecting the delivery of other liquids or secondary recovery extraction.

[0036] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0037] Example

[0038] Please see Figure 1-9As shown, this embodiment discloses a cleaning device for the observation tube of an extraction tank, including an observation tube body 2. In practical applications, the observation tube body 2 is connected to the liquid outlet pipe 1 at the bottom of the extraction tank via flanges at both ends. The middle part of the observation tube body 2 is a transparent tube, allowing observation of the liquid transported by the liquid outlet pipe 1. Inlet 20 and outlet 21 are respectively opened on the outer wall surface of the observation tube body 2 near the liquid outlet pipe 1 at both ends. The inlet 20 is used to insert a device for cleaning the inner wall surface of the observation tube body 2. In this embodiment, it includes a fixing block 3, an elastic cover 33, a first connecting rope 4, an air inlet pipe 6, a second connecting rope 5, and a gripping assembly. Specifically, the fixing block 3 can enter the interior of the observation tube body 2 through the inlet 20. The interior of the fixing block 3 has a transition cavity 31. When the fixing block 3 enters the interior of the observation tube body 2 through the inlet 20, the second connecting rope 5 is provided on the end face of the fixing block 3 facing the central axis of the observation tube body 2, while the first connecting rope 4 is provided on the end face of the fixing block 3 facing the outside of the observation tube body 2.An air inlet is provided at the top of the fixing block 3, located at the connection between the first connecting rope 4 and the fixing block 3. Multiple air outlets are provided on the side wall, and an elastic cover 33 is provided on the outer wall of the fixing block 3. A cavity 34 exists between the elastic cover 33 and the fixing block 3. This cavity 34 can be expanded or compressed by the introduction of gas. Gas is introduced through an air inlet pipe 6 connected to an air inlet end, which fills the transition cavity 31 inside the fixing block 3. It is worth noting that the air inlet pipe 6 is located inside the first connecting rope 4. The first connecting rope 4 has a placement cavity 40 inside, and the first connecting rope 4 has a connecting hole 41 on the outer wall of the observation tube body 2 that communicates with the placement cavity 40. The air inlet pipe 6 is located inside the placement cavity 40. One end of the air inlet pipe 6 is connected to the internal transition cavity 31 of the fixing block 3 through the air inlet, and the other end extends to the outside of the observation tube body 2 through the connecting hole 41 and is connected to the air inlet end. When the fixing block 3 and the elastic cover 33 enter the interior of the observation tube body 2 through the inlet 20, Next, the gripping component is inserted into the interior of the observation tube body 2 through the outlet 21. The gripping component grips the second connecting rope 5 at the bottom of the fixing block 3. Then, the gripping component and the second connecting rope 5 are simultaneously removed from the interior of the observation tube body 2 through the outlet 21. After the second connecting rope 5 is removed, gas is introduced into the air inlet pipe 6 through the air inlet end. The gas enters the internal transition cavity 31 of the fixing block 3 through the air inlet pipe 6 and the air inlet. Immediately afterwards, the gas in the transition cavity 31 enters the elastic cover through the air outlet. In the cavity 34 between 33 and the fixed block 3, gas is filled into the cavity 34, so that the elastic cover 33 expands on the outer wall of the fixed block 3 until the elastic cover 33 comes into contact with and is squeezed against the inner wall of the observation tube body 2. Then, the air supply from the air inlet end to the air inlet pipe 6 is stopped and the air inlet pipe 6 is sealed. Then, the first connecting rope 4 and the second connecting rope 5 are grasped by both hands and moved back and forth, so that the fixed block 3 moves back and forth inside the observation tube body 2, thereby completing the cleaning of the inner wall of the observation tube body 2.

[0039] The aforementioned gripping assembly includes a connecting rod 9 and a gripping rope 91. The outer diameter of the connecting rod 9 is smaller than the diameter of the outlet 21, allowing the connecting rod 9 to enter the internal space of the observation tube body 2 through the outlet 21. The gripping rope 91 is provided on one end face of the connecting rod 9 inside the observation tube body 2, and a through hole 90 is also provided on this end face. The through hole 90 extends to the other end face of the connecting rod 9. The other end of the gripping rope 91 is slidably connected to the connecting rod 9 through the through hole 90, and the other end of the gripping rope 91 extends to the outside of the other end face of the connecting rod 9, so that a gripping ring is formed between the gripping rope 91 and the end face of the connecting rod 9. This gripping ring allows the second connecting rope 5 to pass through, and by pulling the other end of the gripping rope 91, the size of the gripping hole can be adjusted, so that the second connecting rope 5 can be tightly fixed to the end face of the connecting rod 9. Furthermore, to prevent the gripping rope 91 from spontaneously slipping out of the through hole 90, a spherical blocking part 910 is provided at the end of the gripping rope 91 located outside the observation tube body 2. It is worth noting that the gripping rope 91 in this embodiment is specifically an elastic gripping rope 91. When the gripping assembly is not needed, the spherical blocking part 910 pulls the elastic gripping rope 91, allowing the size of the gripping loop formed by the elastic gripping rope 91 on the end face of the connecting rod 9 to vary. When it is necessary to clean the inside of the observation tube body 2, the spherical blocking part 910 is used to pull the gripping rope 91, adjusting the size of the gripping loop formed between the gripping rope 91 and the connecting rod 9 to its minimum, so that the connecting rod 9 can pass through the outlet. When the 21-point entry point enters the interior of the observation tube body 2, the gripping rope 91 is prevented from being squeezed between the connecting rod 9 and the observation tube body 2. After the end of the connecting rod 9 enters the interior of the observation tube body 2, the gripping rope 91 is then pushed towards the interior of the observation tube body 2 through the through hole 90 by the spherical blocking part 910 until the gripping loop between the gripping rope 91 and the connecting rod 9 inside the observation tube body 2 is large enough. Then, the fixing block 3 and the elastic cover 33 can be inserted into the interior of the observation tube body 2 through the inlet 20 of the observation tube body 2. When the fixing block 3 enters the interior of the observation tube body 2, the elastic cover 33 on the surface of the fixing block 3 is not inflated and unfolded. The second connecting rope 5 at the bottom of the fixing block 3 will move towards the inside of the gripping ring as the fixing block 3 moves inside the observation tube body 2. After the bottom end face of the second connecting rope 5 is lower than the end face at the outlet 21 and has moved a long distance, the gripping rope 91 can be pulled by the spherical blocking part 910 to adjust the gripping ring between the gripping rope 91 and the connecting rod 9 to the smallest size, thereby clamping the second connecting rope 5 located in the gripping ring to the end face of the connecting rod 9. Then the connecting rod 9 can be taken out from the interior of the observation tube body 2 through the outlet 21 to remove the second connecting rope 5.

[0040] During the process of the aforementioned fixing block 3 entering the interior of the observation tube body 2, the length of the fixing block 3 needs to be less than the inner diameter of the observation tube body 2, so that the fixing block 3 can fall into the interior of the observation tube body 2 without obstruction after entering the interior of the observation tube body 2.

[0041] A second sealing plug 8 is fitted onto the outer wall of both the first connecting rope 4 and the second connecting rope 5. The second sealing plug 8 can slide on the outer wall of the first connecting rope 4 and the second connecting rope 5 respectively. Before use, the second sealing plug 8 located on the outer wall of the second connecting rope 5 needs to be removed from the outer wall of the second connecting rope 5 so that the second connecting rope 5 can smoothly enter the interior of the observation tube body 2 through the inlet 20. After the second connecting rope 5 exits through the outlet 21 of the observation tube body 2, the second sealing plug 8 is fitted onto the second connecting rope 5 and inserted into the outlet 21. At the same time, the second sealing plug 8 located on the first connecting rope 4 is inserted into the inlet 20 to seal the observation tube body 2. This prevents the residue cleaned from the inner wall of the observation tube body 2 from being discharged through the outlet 21, and prevents the liquid remaining on the inner wall of the liquid outlet pipe 1 from accumulating and moving along the inner wall of the liquid outlet pipe 1 before flowing out from the inlet 20 and affecting the usage environment of the observation tube body 2. It is worth noting that, in order to avoid the second sealing plug 8 affecting the service life of the first connecting rope 4 and the second connecting rope 5, an arc surface is provided on the inner wall surface of the second sealing plug 8. The protruding part of the arc surface faces the direction of the liquid outlet pipe 1, so that the first connecting rope 4 and the second connecting rope 5 are reduced from wear caused by friction during use. Furthermore, to prevent the inlet 20 and outlet 21 on the side wall of the observation tube body 2 from affecting its performance, a first sealing plug 7 is provided on the outer wall of the observation tube body 2 to seal the inlet 20 and outlet 21. An elastic fixing ring 70 is provided on the outer wall of the first sealing plug 7. The elastic fixing ring 70 is sleeved on the outer wall of the observation tube body 2. When it is necessary to seal the inlet 20 and outlet 21, the first sealing plug 7 is rotated to the position of the inlet 20 and outlet 21 and sealed. When it is necessary to clean the inside of the observation tube body 2, the first sealing plug 7 is rotated to another part of the outer wall of the observation tube body 2 by rotating the elastic fixing ring 70, so that the fixing block 3 and the elastic cover 33 can enter the inside of the observation tube body 2 through the inlet 20 for cleaning.

[0042] A sealing rod is inserted at the inlet of the air intake pipe 6. After the air intake end has delivered gas through the air intake pipe 6, the operator needs to hold the first connecting rope 4 and the second connecting rope 5 and pull them together. The air intake pipe 6 will also move with the first connecting rope 4. If the connection between the air intake end and the air intake pipe 6 is not disconnected, the length of the air intake pipe 6 needs to be increased. In this embodiment, the air intake pipe 6 is disconnected from the air intake end, and a sealing rod is inserted at the inlet of the air intake pipe 6 to seal the inlet of the air intake pipe 6. An inclined surface is provided on the inner wall of the observation tube body 2 located at the inlet 20. After the elastic cover 33 on the outer wall of the fixing block 3 has finished cleaning the residue on the inner wall of the observation tube body 2, the sealing rod located at the inlet of the air intake pipe 6 is removed, so that the volume of the cavity 34 between the elastic cover 33 and the fixing block 3 is reduced until the elastic cover 33 returns to its original state. Then, the second sealing plug 8 located on the first connecting rope 4 and the second connecting rope 5 is removed. Holding the first connecting rope 4, it is pulled outward from the observation tube body 2, and the fixing block 3 will be pulled from the inside of the observation tube body 2 to the inlet 20. At this time, the fixing block 3 is close to the inner wall of the observation tube body 2. In order to facilitate the removal of the fixing block 3 from the inlet 20, the inclined surface is provided to facilitate the removal of the fixing block 3 from the inlet 20.
