Description

Technical Field

[0001] The present invention relates to the technical field of extraction equipment, and in particular to a modular camellia oil extraction device. Background Art

[0002] Camellia oil is taken from the seeds of the Camellia oleifera tree of the Theaceae family. The production process of camellia oil can be divided into: shelling, drying, crushing, steaming, oil pressing, and filtering. The processing of camellia oil usually requires multiple steps. The most common camellia oil extraction process mainly uses solvent extraction. Solvent leaching is a method of extracting oil from the billet or pre-pressed cake by utilizing the oil-dissolving properties of certain organic solvents (such as n-hexane, petroleum ether, and anhydrous ethanol).

[0003] Traditional camellia oil extraction processes generally use mechanical pressing or solvent extraction methods, which have problems such as low oil extraction rate and insufficient mixing uniformity. Existing pressing equipment is prone to incomplete solid-liquid separation when processing raw materials, resulting in limited contact area between the oil phase and the extract, and residual oil content as high as 15% to 20%. Conventional filtering structures cannot achieve dynamic countercurrent circulation during the extrusion process, the solvent utilization rate drops by about 30%, and the static filter holes are easily clogged by fiber impurities, causing pressure loss. The existing technology lacks effective utilization of pressure changes in the extrusion cavity, and fails to combine gas backwashing to achieve the self-cleaning function of the filter holes. After 3 to 4 hours of continuous operation, the equipment will experience a production capacity decay of more than 15%. Summary of the Invention

The sealing connecting rod extends to the outside of the discharge pipe at one end away from the sealing end and is connected to a limiting block. The cross-sectional diameter of the lower end of the sealing connecting rod is the same as the inner diameter of the sealing end.

[0008] Furthermore, the driving member includes a mounting groove opened on the connecting ring and located at the lower part of its inner cavity, a buffer airbag is installed on the inner bottom surface of the mounting groove, the inner top surface of the buffer airbag is connected to the connecting ring through a second connecting tube, and a one-way exhaust pipe is connected through the annular inner side surface of the buffer airbag.

[0009] Furthermore, the extraction component also includes an adjustment component arranged in the cover body, the adjustment component includes a connecting groove arranged near the middle position inside the cover body, a first mounting cylinder is installed inside the cover body near the upper part of the connecting groove, the first mounting cylinder is elastically and slidably connected to the inside of the first piston rod, the lower end of the first piston rod extends to a position near the lower part of the connecting groove and is fixedly connected to a sealing plate, the sealing plate is in abutting connection with the connecting groove, a main air pipe is connected through the middle of the annular side surface of the connecting groove, a control valve is provided on the annular side surface of the main air pipe, and the main air pipe extends from one end of the connecting groove to a position near the buffer airbag and is connected through it.

[0012] Furthermore, the limit assembly also includes a second mounting cylinder installed on the top surface of the shell, and the interior of the second mounting cylinder is elastically and slidably connected to a third piston rod, the lower end of the third piston rod passes through the top wall of the shell and extends to a position close to the baffle, and the upper part of the mounting ring is provided with an air supply annular pipe, and each of the second mounting cylinders is connected to each other through the air supply annular pipe, and the annular side surface of the main air supply pipe is passed through a secondary air supply pipe, and the secondary air supply pipe extends from one end of the main air supply pipe to a position close to the air supply annular pipe and is connected to it, and the secondary air supply pipe is arranged between the control valve and the connecting groove on the main air supply pipe.

[0013] Furthermore, the lower end of the third piston rod is cylindrical.

[0014] Furthermore, the connecting column is divided into an upper end and a lower end, the outer diameter of the upper end of the connecting column is smaller than the outer diameter of the lower end thereof, and the annular explosion ring is slidably connected to the lower end of the connecting column.

[0015] Compared with the known prior art, the technical solution provided by the present invention: 1. The main conical bucket and the secondary conical bucket squeeze the raw materials between them so that the oil in the camellia seed raw materials can be better mixed with the extract. It is worth noting that in the process of the main conical bucket moving downward, since the end of the first connecting pipe away from the connecting ring is connected to the oil pipe on the hydraulic rod, during the operation of the hydraulic rod, part of the hydraulic oil enters the interior of the connecting ring through the first connecting pipe to squeeze the movable pressure plate. Under the action of the extrusion force, the movable pressure plate squeezes the gas under it. The extrusion force causes the gas under it to enter the interior of the annular explosion ring through the first air pipe, and then be discharged through the explosion holes on the annular explosion ring, continuously generating bubbles in the liquid. The movement and rupture of the bubbles will generate shear force, which promotes the mixing of the raw materials.

[0016] 2. As the volume of gas entering the upper portion of the main conical bucket gradually increases, excess gas that cannot be discharged in time enters the blocked filter holes of the main conical bucket, squeezing the extracted impurities. This squeezing force causes the extracted impurities to move toward the upper portion of the secondary conical bucket. Impurities in the blocked filter holes enter between the main and secondary conical buckets, thereby clearing the blocked filter holes of the main conical bucket. Simultaneously, during this process, the main conical bucket is controlled to move upward within the tank body to extract air, further increasing the pressure differential across the main conical bucket, further enhancing the cleaning effect of impurities within the filter holes of the main conical bucket. It is worth noting that with each reciprocating movement of the main conical bucket, gas enters the buffer airbag. That is, the more times the main conical bucket filters, the greater the likelihood of the filter holes becoming clogged. The greater the amount of gas stored in the buffer airbag, the greater the amount of gas entering the tank body during cleaning. This greater impact of the gas on the impurities within the filter holes of the main conical bucket, resulting in a more effective cleaning effect.

[0017] 3. The secondary conical bucket is slidably connected to the lower end of the connecting column, and a gap is generated between the secondary conical bucket and the connecting column. The extraction residue extracted on the annular explosion ring falls into the inside of the slag discharge port through the conical surface of the secondary conical bucket, and is then discharged through the slag discharge port, thereby achieving the effect of quickly processing the extraction residue. It is worth noting that the gas entering between the main conical bucket and the secondary conical bucket will also be discharged through the gap between the secondary conical bucket and the connecting column. During the flow of gas, the extraction residue will also be pushed, further improving the effect of extracting residue discharge. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Example: Refer to Figures 1 to 11 A modular camellia oil extraction device comprises a tank body 1 and a cover body 2, and is characterized in that it further comprises: A slag discharge port 5 is provided at the bottom of the tank body 1, a liquid discharge pipe 6 is provided through the middle of the slag discharge port 5, an extraction component 3 is provided inside the tank body 1, and a connecting column 8 is connected to the upper end of the liquid discharge pipe 6; Among them, the extraction component 3 includes two groups of hydraulic rods 31 symmetrically arranged on the top surface of the cover body 2, the output end of the hydraulic rod 31 extends to the interior of the cover body 2 and is connected to a main conical bucket 32, and the main conical bucket 32 ​​is penetrated with evenly distributed filter holes, and the inner side surface of the tank body 1 is slidably connected to a secondary conical bucket 33 used in conjunction with the main conical bucket 32, and a connecting ring 34 is provided in the middle of the outer side surface of the tank body 1, and the inner top surface of the connecting ring 34 is penetrated with a first connecting pipe 35, and the inner side surface of the connecting ring 34 is slidably connected with a movable pressure plate 36, and the bottom of the annular inner side surface of the movable pressure plate 36 is connected to a first air supply pipe 37, and the top surface of the secondary conical bucket 33 is provided with an annular explosion ring 38, and the end of the first air supply pipe 37 away from the connecting ring 34 passes through the inner wall of the tank body 1 and extends to a position close to the annular explosion ring 38 and is connected to its internal cavity, and the main conical bucket 32 ​​is slidably connected to the connecting column 8.

[0024] It is worth noting that the outside of the liquid discharge pipe 6 and the slag discharge port 5 are both connected to a discharge pipe, wherein the discharge pipe connected to the slag discharge port 5 is provided with a control valve; further, when extraction work is required, first, select mature and healthy camellia fruits to ensure that the seeds are not affected by diseases and insect pests, clean the picked camellia seeds, remove surface impurities and soil, then dry them, remove excess water, use mechanical equipment to shell them, and break the camellia seeds into small pieces. Further, mix the broken seeds with the extraction solvent. After mixing, the mixed raw materials are transported to the position between the main conical bucket 32 ​​and the secondary conical bucket 33 inside the tank body 1 through the feeding pipe. After the above work is completed, the hydraulic system of the hydraulic rod 31 sends high-pressure oil to the oil inlet of the hydraulic rod 31 through the pump, driving the hydraulic rod 31 to start working, and driving the main conical bucket during the movement of the hydraulic rod 31. As the main conical hopper 32 moves toward the secondary conical hopper 33, the primary and secondary conical hoppers 32 and 33 squeeze the raw material between them, allowing the oil in the camellia seed raw material to mix better with the extract. It is noteworthy that as the primary conical hopper 32 moves downward, because the end of the first connecting tube 35 away from the connecting ring 34 is connected to the oil pipe on the hydraulic rod 31, during the operation of the hydraulic rod 31, some hydraulic oil enters the interior of the connecting ring 34 through the first connecting tube 35, squeezing the movable pressure plate 36. Under the action of the squeezing force, the movable pressure plate 36 squeezes the gas below it, causing it to enter the interior of the annular explosion ring 38 through the first air supply pipe 37. The gas is then discharged through the explosion holes in the annular explosion ring 38, continuously generating bubbles in the liquid. The movement and rupture of the bubbles generate shear force, promoting mixing between the raw materials. This gas-liquid shearing effect can effectively improve the mixing effect. Furthermore, as the bubbles move in the liquid, they drive convection in the surrounding liquid, thereby accelerating the extraction of the raw materials.

[0025] Furthermore, when the bubbles pass through the conical filter bucket, the airflow will be compressed and accelerated when the bubbles enter the conical filter bucket, and the relative speed of the bubbles and the liquid will increase. This accelerated fluid will generate a large shear force, making the bubbles easy to break or split into smaller bubbles, and as the bubbles enter the gradually shrinking conical area, the bubbles will collide with each other or come into contact with the bucket wall. Under the action of these collisions and pressure changes, the large bubbles are split into multiple smaller bubbles. The smaller bubbles have a larger specific surface area, so they can react or dissolve with the liquid more effectively. At the same time, the fine bubbles formed after the bubbles burst increase the contact area between the liquid and the gas. The fine bubbles promote full contact between the solvent and the camellia seeds, allowing the solvent to penetrate into the raw materials more effectively, thereby dissolving and extracting oil more efficiently, and the bubble burst can The mixing of liquid and solid is made more uniform, and in the process of using solvent to extract camellia oil, the good mixing effect can ensure that the solvent can be evenly distributed to all raw materials, avoiding solvent waste or incomplete extraction. At the same time, the bursting of small bubbles helps to improve the mixing efficiency, ensure that the extraction process is more efficient, and ensure the extraction effect of camellia oil in the process of extraction. In the process of the main conical bucket 32 ​​moving upward, the liquid on the upper part of the main conical bucket 32 ​​returns to between the main conical bucket 32 ​​and the secondary conical bucket 33, over and over again, further improving the mixing effect of the oil in the raw material and the extract, ensuring that the solvent can fully contact all raw materials during the extraction process, thereby reducing solvent waste and improving the extraction efficiency of oil. The solution reflux process helps to maximize the solubility of the solvent in each cycle, further improving the extraction effect.

[0026] Furthermore, the speed at which the hydraulic rod 31 moves can be controlled to control the amount of hydraulic oil entering the connecting ring 34 per unit time, that is, the amount of gas squeezed by the movable pressure plate 36 on the connecting ring 34 can be controlled to control the speed at which the gas enters the annular explosion ring 38. When the speed at which the gas enters the annular explosion ring 38 changes, according to the gas compression principle such as Boyle's law, if the gas is compressed more severely, the bubbles will become smaller, the gas volume will decrease, and the pressure will increase. If the pressure is low when the gas is released, the bubbles will be larger, and bubbles of different sizes will be generated inside the tank body 1. The rising speeds of bubbles of different sizes in the extraction solution are different. Smaller bubbles have a larger surface area, which can improve the mass transfer efficiency of the gas-liquid interface and promote mass transfer between substances. When larger bubbles flow in the extraction solution, they will contact and exchange with the camellia seed raw material and the substances in the camellia seed raw material, thereby promoting the mass transfer process of the substances. At the same time, the movement of bubbles can drive the surrounding liquid to form convection, accelerate the diffusion and mixing rate between substances, and the movement of large bubbles will drive the surrounding liquid to form vortexes and convection, thereby achieving mixing and homogenization of the camellia seed raw materials and the interior of the camellia seed raw materials, thereby further improving the overall extraction effect.

[0027] Reference Figures 3 to 7 The extraction component 3 also includes an auxiliary component arranged inside the drainage pipe 6; the auxiliary component includes a connecting end 47, a sealing end 48, and a flow end 49 which are sequentially opened on the inner side of the drainage pipe 6 from top to bottom. The inner diameters of the connecting end 47, the sealing end 48, and the flow end 49 increase sequentially. The sealing end 48 is internally slidably connected with a sealing connecting rod 46. The end of the sealing connecting rod 46 away from the sealing end 48 extends to the outside of the drainage pipe 6 and is connected to the limiting block 45. The cross-sectional diameter of the lower end of the sealing connecting rod 46 is the same as the inner diameter of the sealing end 48. A driving member that provides a power source for the movement of the sealing connecting rod 46 is provided inside the connecting ring 34.

[0028] The driving member includes a mounting groove 41 opened on the connecting ring 34 and located at the lower part of its inner cavity. A buffer airbag 42 is installed on the inner bottom surface of the mounting groove 41. The inner top surface of the buffer airbag 42 is connected to the connecting ring 34 through a second connecting tube 43. The annular inner side surface of the buffer airbag 42 is penetrated by a one-way exhaust pipe 44.

[0029] It is worth noting that before the raw materials are put into the tank body 1, the output end of the hydraulic rod 31 is driven to move a distance and then the oil supply is stopped. Under the action of the extrusion force, the movable pressure plate 36 squeezes the gas below it. The extrusion force will also cause the gas below it to pass through the second connecting pipe 43 into the interior of the buffer airbag 42, and then enter the interior of the drain pipe 6 through the one-way exhaust pipe 44, and gradually be discharged through the gap between the sealing connecting rod 46 and the flow end 49. However, by controlling the size of the gap between the sealing connecting rod 46 and the flow end 49 and the amount of gas entering the drain pipe 6 per unit time inside the buffer airbag 42, the amount of gas entering the drain pipe 6 per unit time is achieved. The effect of making the amount of gas inside greater than the amount of gas discharged through the gap between the sealing end 48 and the flow end 49 per unit time is a conventional technical means in the prior art, so it will not be described in detail here; therefore, as the gas pressure inside the drain pipe 6 changes, the gas gradually squeezes the sealing connecting rod 46, and the squeezing force causes the sealing connecting rod 46 to gradually move upward inside the flow end 49 and enter the interior of the sealing end 48. Since the cross-sectional diameter of the lower end of the sealing connecting rod 46 is the same as the inner diameter of the sealing end 48, the sealing end 48 is sealed; ensuring that during the extraction work, part of the extract can easily enter the interior of the drain pipe 6, causing unnecessary waste of extraction solution; Furthermore, when the extraction work is completed, the hydraulic rod 31 is controlled to drive the main conical bucket 32 ​​to move downward until the lower part of the main conical bucket 32 ​​squeezes the slag between the main conical bucket 32 ​​and the annular explosion ring 38. In this process, the squeezing force causes the solution after the extraction to pass through the filter holes on the main conical bucket 32, and then the solution is in the upper part of the main conical bucket 32. After the above operation is completed, the operator can open the control valve connected to the drain pipe 6, and the gas inside the drain pipe 6 is discharged through the control valve. The squeezing force of the gas on the connecting end 47 disappears, and the limit block 45 and the liquid are separated. Under the action of body weight, the liquid after extraction enters the interior of the drain pipe 6 through the through hole on the connecting column 8, and is discharged through the gap between the sealed connecting rod 46 and the flow end 49, thereby achieving the purpose of collecting the solution. It is worth noting that by setting the position of the through hole on the connecting column 8 and controlling the amount of solid raw material camellia seeds, it is ensured that it is moved to the main conical bucket 32, and the through hole on the connecting column 8 is located close to the inner bottom surface of the main conical bucket 32, thereby ensuring the discharge effect of the solution. This is a conventional technical means in the prior art, so it will not be elaborated here.

[0030] Furthermore, when the movable pressure plate 36 squeezes the gas inside the connecting ring 34 and moves downward, the gas inside the connecting ring 34 enters the interior of the buffer airbag 42 through the second connecting tube 43, that is, enters the interior of the buffer airbag 42 through the pipeline and the one-way valve. Under the action of the gas squeezing force, the buffer airbag 42 elastically expands, thereby achieving the effect of caching the gas.

[0031] Reference Figure 5 and Figure 8 The extraction component 3 also includes an adjustment component arranged in the cover body 2, which includes a connecting groove 75 arranged near the middle position inside the cover body 2, and a first mounting cylinder 72 is installed on the upper part of the connecting groove 75 inside the cover body 2. The first piston rod 73 is elastically and slidably connected inside the first mounting cylinder 72, and the lower end of the first piston rod 73 extends to a position near the lower part of the connecting groove 75 and is fixedly connected to a sealing plate 74. The sealing plate 74 is in contact with the connecting groove 75, and the main air supply pipe 71 is connected through the middle of the annular side surface of the connecting groove 75. A control valve is provided on the annular side surface of the main air supply pipe 71, and the end of the main air supply pipe 71 away from the connecting groove 75 extends to a position near the buffer airbag 42 and is connected through it.

[0032] After the solution is discharged, the control valve connected to the discharge pipe 6 is closed, and the control valve on the main air supply pipe 71 is opened. The gas buffered in the buffer airbag 42 enters the interior of the communication groove 75 through the control valve on the main air supply pipe 71 and squeezes the sealing plate 74. The squeezing force causes the sealing plate 74 to drive the first piston rod 73 to overcome the elastic force between the sealing plate 74 and the first mounting cylinder 72 and move downward. A gap is generated between the sealing plate 74 and the cover body 2, and the gas enters the interior of the cover body 2 through the gap. It is worth noting that in the initial state, the sealing plate 74 and the cover body 2 are in a tight state to prevent the solution from entering the communication groove 75. When the gas enters the cover body 2, as the amount of gas entering the upper part of the main conical bucket 32 ​​gradually increases, the excess gas that cannot be discharged in time enters the clogged filter hole on the main conical bucket 32 ​​and squeezes the extracted impurities. The squeezing force causes the extracted impurities to move toward the upper part of the secondary conical bucket 33. The impurities in the clogged filter hole enter between the main conical bucket 32 ​​and the secondary conical bucket 33, thereby cleaning the clogged filter hole on the main conical bucket 32. It is worth noting that, during the above process, the main conical bucket 32 ​​is controlled to move upward within the tank body 1 to perform the air extraction operation, thereby further increasing the air pressure difference on both sides of the main conical bucket 32, thereby further improving the cleaning effect of impurities inside the filter holes of the main conical bucket 32. It is worth noting that with each reciprocating movement of the main conical bucket 32, gas enters the interior of the buffer airbag 42. In other words, the more times the main conical bucket 32 ​​performs filtering, the greater the possibility of the filter holes in the main conical bucket 32 ​​being blocked. The greater the amount of gas buffered in the buffer airbag 42, that is, the greater the amount of gas entering the tank body 1 during the cleaning operation, the greater the impact of the gas on the impurities inside the filter holes of the main conical bucket 32, and the more obvious the cleaning effect.

[0033] Reference Figures 9 to 11 The adjustment assembly also includes a piston cylinder 77 evenly connected to the bottom surface of the annular explosion ring 38. A second piston rod 78 is sleeved on the outside of the piston cylinder 77. The piston cylinder 77 and the second piston rod 78 are elastically slidably connected. The lower end of the piston cylinder 77 extends to the outside of the tank body 1 and is connected to the mounting ring 70. A limit assembly is provided on the lower part of the annular side of the piston cylinder 77.

[0034] The limiting assembly includes a shell 710 installed at the lower part of the outer side surface of the piston cylinder 77. The inner side surface of the shell 710 close to the piston cylinder 77 is connected with a connecting pipe 711. The shell 710 and the piston cylinder 77 are connected through the connecting pipe 711. The inner side surface of the shell 710 away from the connecting pipe 711 is elastically connected with a baffle 712 through a spring 79. The baffle 712 and the connecting pipe 711 are in abutting connection.

[0035] The limiting assembly also includes a second mounting cylinder 713 mounted on the top surface of the shell 710, and the interior of the second mounting cylinder 713 is elastically and slidably connected to a third piston rod 714, and the lower end of the third piston rod 714 passes through the top wall of the shell 710 and extends to a position close to the baffle 712. An air supply annular pipe 715 is provided on the upper part of the mounting ring 70, and each second mounting cylinder 713 is communicated with each other through the air supply annular pipe 715. A secondary air supply pipe 76 is connected to the annular side surface of the main air supply pipe 71, and the secondary air supply pipe 76 extends from one end of the main air supply pipe 71 to a position close to the air supply annular pipe 715 and is communicated with it. The secondary air supply pipe 76 is arranged on the main air supply pipe 71 between the control valve and the connecting groove 75.

[0036] Then, the air in the second cylinder 713 is pushed upwards and the air in the second cylinder 713 is pushed downwards, thereby releasing the air from the cylinder 713 and releasing the air from the cylinder 714. After the second piston rod 78 and the secondary conical bucket 33 move downward, the connecting column 8 is divided into an upper end and a lower end, and the outer diameter of the upper end of the connecting column 8 is smaller than the outer diameter of the lower end thereof. The secondary conical bucket 33 is slidably connected to the lower end of the connecting column 8, and a gap is generated between the secondary conical bucket 33 and the connecting column 8. The extracted residue on the annular explosion ring 38 falls into the interior of the slag discharge port 5 through the conical surface of the secondary conical bucket 33, and is then discharged through the slag discharge port 5, thereby achieving the effect of quickly processing the extracted residue. It is worth noting that the gas entering between the main conical bucket 32 ​​and the secondary conical bucket 33 will also be discharged through the gap between the secondary conical bucket 33 and the connecting column 8, and will also push the extracted residue during the gas flow, further improving the effect of extracting the residue.

[0037] In the initial state, the baffle 712 and the connecting tube 711 are in a tight state, thereby limiting the position of the sub-conical bucket 33, thereby avoiding the problem of the sub-conical bucket 33 moving and causing solution leakage during the extraction process; at the same time, the elastic force of the elastic connection between the third piston rod 714 and the second mounting cylinder 713 is smaller than the elastic force of the elastic connection between the second piston rod 78 and the second piston rod 78. The magnitude of the elastic force can be controlled by the material and size of the elastic member, thereby ensuring that in the process of gradually decreasing gas exhaust gas extrusion pressure, the second piston rod 78 can first be reset under the action of the elastic force of the elastic member to restore the elastic deformation, ensuring that the third piston rod 714 will only reset after the baffle 712 moves to the initial state, that is, restricting the baffle 712, ensuring the restricting effect of the third piston rod 714 on the baffle 712.

[0038] It is worth noting that the difference in inner diameter between the flow end 49 and the sealing connecting rod 46 is three to five centimeters. On the one hand, it avoids the problem that the distance between the sealing connecting rod 46 and the flow end 49 is too small, which reduces the oil discharge speed in the subsequent oil discharge process. On the other hand, it avoids the problem that the distance between the sealing connecting rod 46 and the flow end 49 is too large, the amount of gas discharged per unit time is large, and the gas cannot normally squeeze the sealing connecting rod 46, thereby ensuring the smoothness of the overall structure during operation.

[0039] It is worth noting that a one-way valve is provided on the one-way exhaust pipe 44 to prevent the solution from entering the interior of the buffer airbag 42, and a gas permeable membrane can also be installed on the one-way exhaust pipe 44 to prevent liquid backflow. As for how to reduce friction and ensure sealing between the main conical bucket 32 ​​and the inner wall of the tank, reference can be made to the working design of the piston rod in the prior art. This is a conventional technical means in the prior art, so it will not be elaborated here.

[0040] Reference Figure 4 The bottom of the annular inner surface of the connecting ring 34 corresponds to the position of the first gas pipe 37 and is connected with a one-way air inlet pipe 39. The one-way air inlet pipe 39 includes a pipeline and a one-way valve. During the upward movement of the main conical bucket 32, the hydraulic pressure inside the connecting ring 34 refluxes. Under the action of the air pressure difference, the external gas enters the interior of the connecting ring 34 through the one-way air inlet pipe 39 to replenish the gas inside the connecting ring 34 and ensure overall smoothness. It is worth noting that the one-way air inlet pipe 39 can be connected to a gas tank of nitrogen, carbon dioxide, etc. to further improve the extraction effect. This is a conventional technical means in the prior art, so it will not be described here.

[0041] Reference Figure 10The lower end of the third piston rod 714 is cylindrical, ensuring that when the third piston rod 714 cancels the restriction on the baffle 712, the friction between the third piston rod 714 and the baffle 712 is reduced, ensuring the normal movement of the third piston rod 714.
