Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of reduced-pressure drying of drilling fluid filtration loss agents, and specifically relates to a reduced-pressure drying device for drilling fluid filtration loss agents. Background Art
[0002] A drilling fluid filtration loss agent is a chemical agent added to drilling fluid to ensure the stable performance of the drilling fluid and reduce the filtration of harmful liquids into the formation. Most filtration loss agents are water-soluble high-molecular compounds, which can adsorb on the surface of clay to form an adsorption layer, preventing clay particles from flocculating and growing larger; they can also stabilize the fine particles dispersed under the action of the drilling fluid circulation and stirring through adsorption, ensuring a sufficient proportion of fine particles, so that the drilling fluid forms a thin and dense filter cake, reducing the filtration loss. During the drilling process, the filtration of the drilling fluid is inevitable, but too large a filtration loss is likely to cause shale swelling and collapse, resulting in unstable wellbore. The thickening of the filter cake will reduce the wellbore diameter, causing a large torque on the rotating drill string, and causing swabbing and pressure fluctuations during tripping, which are likely to cause problems such as differential sticking. Therefore, using a filtration loss agent to appropriately control the filtration loss is one of the important properties of drilling fluid and is of great significance for ensuring the safe and efficient progress of drilling operations.
[0003] After the reduced-pressure drying device processes and discharges the drilling fluid filtration loss agent, some drilling fluid filtration loss agent will remain on the inner wall of the drying tank, thus remaining in the reduced-pressure drying device, and then it is necessary for the staff to manually clean the inside of the device, which increases the work intensity of the staff. Summary of the Invention
[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: A reduced-pressure drying device for drilling fluid filtration loss agents described in the present invention includes: A workbench, on the top of which a drying tank is fixedly connected, on the top of the drying tank a vacuum pump is fixedly connected, at the axis center of the top of the drying tank a feeding component is fixedly connected, on the top of the workbench a transmission component is fixedly connected, and on the side of the drying tank away from the feeding component an discharging component is fixedly connected; A rotating component, which is used to turn the drilling fluid filtration loss agent in the drying tank, both ends of the rotating component are rotatably connected to the inside of the drying tank, and the output end of the transmission component is fixedly connected to the rotating component; The rotating component includes a rotating shaft, both ends of the rotating shaft are rotatably connected to the inner side of the drying tank, one end of the rotating shaft is fixedly connected to the output end of the transmission component, the side of the rotating shaft is evenly provided with rake teeth, and a contact mechanism is fixedly connected to the side of the rotating shaft away from the rake teeth; the output end of the transmission component drives the rotating shaft to rotate in the drying tank, so that the rotating shaft drives the rake teeth to rotate in the inner cavity of the drying tank, the rake teeth rotate slowly, continuously turning the drilling fluid loss reducer, making the drilling fluid loss reducer evenly heated, accelerating water evaporation. When the processing work is completed, the drilling fluid loss reducer in the drying tank is discharged by opening the discharging component. At the same time, when the drilling fluid loss reducer in the drying tank is slowly discharged through the discharging component, the transmission component is adjusted, and the output end of the transmission component drives the rotating shaft to rotate rapidly. Thus, under the action of centrifugal force, the contact mechanism moves away from the inner side of the rotating shaft towards the inner side of the drying tank. By the rotation of the rotating shaft, the contact mechanism cleans the inner side of the drying tank, thus avoiding that after processing the materials in the drying tank, some residues of the drilling fluid loss reducer will adhere to the inner wall of the drying tank and dry and solidify in the drying tank, resulting in deterioration; Preferably, the contact mechanism includes a sliding rod, the side of the sliding rod is slidably connected to the inner side of the rotating shaft, one end of the sliding rod away from the rotating shaft is fixedly connected to a sliding plate, both sides of the sliding plate are in contact with the inner side of the rotating shaft, a scraping plate is fixedly connected to the side of the sliding plate, a contact plate is fixedly connected to the side of the sliding plate away from the scraping plate, a first spring is sleeved on the sliding rod, one end of the first spring is fixedly connected to the inner side of the rotating shaft, and the other end of the first spring is fixedly connected to the sliding plate. When the drilling fluid loss reducer in the drying tank is slowly discharged through the discharging component, the transmission component is operated, and the output end of the transmission component drives the rotating shaft to rotate rapidly. Under the action of centrifugal force, the sliding rod drives the sliding plate to slide in the inner side of the rotating shaft, so that the sliding plate drives the connecting plate and the scraping plate to move towards the inner wall of the drying tank, so that the scraping plate scrapes the materials accumulated and solidified on the inner wall of the drying tank. At the same time, since the angle of the scraping plate is smaller than the set angle of the contact plate, the contact plate can contact and clean the drilling fluid loss reducer solidified on the inner wall of the drying tank, thus avoiding the scraping plate moving against the inner side of the drying tank, which will cause frictional damage to the inner side of the drying tank and reduce the service life of the inner wall of the drying tank. At the same time, by continuing to rotate the rotating shaft, the contact plate can move against the inner wall of the drying tank, so that the contact plate can move against the place cleaned by the scraping plate. At the same time, since the material of the contact plate is rubber material, it can avoid frictional damage to the inner wall of the drying tank when cleaning and contacting the inner wall of the drying tank for a long time; Preferably, the discharging component includes a discharging pipe, a bracket is fixedly connected to the side of the discharging pipe, a first motor is fixedly connected to one end of the discharging pipe, a spiral blade is rotatably connected to the inner side of the discharging pipe, the output end of the first motor is fixedly connected to the spiral blade, a discharging mechanism is fixedly connected to the side of the discharging pipe away from the bracket, a gate valve mechanism is fixedly connected to the side of the discharging mechanism, and the top of the discharging mechanism is fixedly connected to the inner side of the drying tank; when the filtrate reducer of the drilling fluid in the drying tank is processed, by opening the gate valve mechanism, the filtrate reducer of the drilling fluid in the drying tank enters the discharging mechanism, and at the same time, by turning on the first motor, the output end of the first motor drives the spiral blade to rotate in the discharging pipe, thereby driving the filtrate reducer of the drilling fluid to discharge, so as to prevent the filtrate reducer of the drilling fluid from deteriorating or sticking due to excessive temperature during the discharging process; Preferably, the discharging mechanism includes a discharging port, the bottom of the discharging port is fixedly connected to the inner side of the discharging pipe, the top of the discharging port is fixedly connected to the inner side of the drying tank, a fixing frame is fixedly connected to the inner side of the discharging port, a guide rod is fixedly connected to the fixing frame, a limiting mechanism is fixedly connected to the end of the guide rod away from the fixing frame, a moving frame is slidably connected to the guide rod, scraping plates are fixedly connected to both sides of the moving frame, a second spring is sleeved on the guide rod, the top of the second spring is fixedly connected to the fixing frame, the other end of the second spring is fixedly connected to the moving frame, and the limiting mechanism is arranged below the gate valve mechanism; when discharging the filtrate reducer of the drilling fluid in the drying tank, by opening the gate valve mechanism, the filtrate reducer of the drilling fluid in the drying tank continuously enters the discharging pipe through the discharging port, so that the filtrate reducer of the drilling fluid during discharging impacts the moving frame, thereby causing the moving frame to drive the scraping plates to move downward on the guide rod. At the same time, when discharging, when the impact speed of the material on the moving frame is less than the tensile force of the second spring, the moving frame moves upward through the tensile force of the first spring, so that the moving frame drives the scraping plates to clean the inner side of the discharging port, thereby avoiding the phenomenon that the material hangs on the inner side of the discharging port due to excessive temperature during the discharging of the material. Thus, the inner wall of the discharging port is cleaned by the scraping plates. At the same time, when the moving frame drives by the reset of the second spring and moves towards the limiting mechanism, the limiting mechanism can buffer the moving frame; Preferably, the limiting mechanism includes a limiting frame. The side of the limiting frame is fixedly connected to the inner side of the discharge port. A through hole is formed in the middle of the limiting frame. The inner side of the through hole is fixedly connected to the side of the guiding rod. A buffer frame is fixedly connected to one side of the limiting frame close to the moving frame. A third spring is fixedly connected to the inner side of the buffer frame. The other end of the third spring is fixedly connected to a buffer block. When the moving frame is driven by the reset of the second spring to move towards the limiting frame, the side of the moving frame comes into contact with the buffer frame. A buffer block is arranged in the middle of the inner side of the buffer frame, and the material of the buffer block is rubber. Therefore, when the moving frame abuts and squeezes against the buffer block, the buffer block simultaneously buffers the impact of the reset of the moving frame through the buffer work of the third spring, thus avoiding excessive impact force between the moving frame and the limiting frame, which may cause impact damage to the moving frame and the scraping plate. At the same time, through the impact vibration between the moving frame and the buffer frame, the remaining material adhering to the scraping plate can be shaken off, thus avoiding the remaining material of the drilling fluid filtrate reducer from adhering to the scraping plate. Preferably, the feeding component includes a feeding pipe. The bottom of the feeding pipe is fixedly connected to the inner side of the drying tank. An installation frame is fixedly connected to the inner side of the feeding pipe. A second motor is fixedly connected to the top of the installation frame. A diffusion mechanism is rotatably connected to the side of the installation frame. The output end of the second motor is fixedly connected to the diffusion mechanism. When adding the drilling fluid filtrate reducer into the drying tank, the drilling fluid filtrate reducer continuously enters the drying tank. By turning on the second motor, the output end of the second motor drives the diffusion mechanism to rotate in the feeding pipe, so that the diffusion mechanism diffuses the continuously passing material in the feeding pipe, thus avoiding the phenomenon of accumulation and blockage during the feeding of the drilling fluid filtrate reducer due to its relatively wet nature. Preferably, the diffusion mechanism includes a connecting shaft. The top of the connecting shaft is fixedly connected to the output end of the second motor. Diffusion frames are fixedly connected to both sides of the connecting shaft. An expansion rod is fixedly connected to the inner side of the diffusion frame. The end of the expansion rod away from the diffusion frame is fixedly connected to a connecting plate. The side of the connecting plate is in contact with the inner side of the diffusion frame. A fourth spring is sleeved on the expansion rod. One end of the fourth spring is fixedly connected to the connecting plate, and the other end of the fourth spring is fixedly connected to the inner side of the diffusion frame. When the output end of the second motor drives the connecting shaft to rotate, the diffusion frames are driven by the connecting shaft to diffuse the continuously passing material in the feeding pipe. At the same time, due to the centrifugal force generated when the diffusion frames rotate, the connecting plate is separated from the inner side of the diffusion frame through the expansion rod, so that the connecting plate cleans the inner wall of the feeding pipe, thus avoiding the continuous passage of wet material through the feeding pipe, which may adhere to the inner wall of the feeding pipe and cause the phenomenon of material accumulation and hanging.
[0005] The beneficial effects of the present invention are as follows: 1. In the present invention, by providing a contact mechanism, when the fluid loss reducer in the drying tank is slowly discharged through the discharge component, by operating the transmission component, the output end of the transmission component drives the rotating shaft to rotate rapidly. Under the action of centrifugal force, the sliding rod drives the sliding plate to slide inside the rotating shaft, so that the sliding plate drives the connecting plate and the scraper to move towards the inner wall of the drying tank, and the scraper scrapes the dry and solidified material accumulated on the inner wall of the drying tank. At the same time, since the angle of the scraper is smaller than the set angle of the contact plate, the contact plate can contact and clean the dry and solidified fluid loss reducer on the inner wall of the drying tank, thus preventing the scraper from moving against the inner side of the drying tank, which may cause frictional damage to the inner side of the drying tank and reduce the service life of the inner wall of the drying tank. At the same time, as the rotating shaft continues to rotate, the contact plate can move against the inner wall of the drying tank, so that the contact plate can move against the place after the scraper has cleaned. At the same time, since the material of the contact plate is rubber, it can prevent frictional damage to the inner wall of the drying tank when cleaning and contacting the inner wall of the drying tank for a long time.
[0006] 2. In the present invention, by providing a discharge component, when the fluid loss reducer in the drying tank is processed, by opening the gate valve mechanism, the fluid loss reducer in the drying tank enters the discharge mechanism. At the same time, by turning on the first motor, the output end of the first motor drives the spiral blade to rotate in the discharge pipe, thereby driving the fluid loss reducer to perform the discharge work, thus preventing the fluid loss reducer from deteriorating or sticking due to excessive temperature during the discharge process.
[0007] 3. In the present invention, by providing a discharge mechanism, when discharging the fluid loss reducer in the drying tank, by opening the gate valve mechanism, the fluid loss reducer in the drying tank continuously enters the discharge pipe through the discharge port, and the fluid loss reducer during discharge impacts the moving frame, so that the moving frame drives the scraping plate to move downward on the guide rod. At the same time, when discharging, when the impact speed of the material on the moving frame is less than the tensile force of the second spring, the moving frame moves upward under the tensile force of the first spring, so that the moving frame drives the scraping plate to clean the inner side of the discharge port, thus preventing the material from getting stuck on the inner side of the discharge port due to excessive temperature during the discharge process. Thus, the scraping plate cleans the inner wall of the discharge port. At the same time, when the moving frame moves towards the limiting mechanism under the reset of the second spring, the limiting mechanism can buffer the moving frame.
[0008] 4. The present invention is provided with a diffusion mechanism. When the output end of the second motor drives the connecting shaft to rotate, the connecting shaft drives the diffusion frame to diffuse the materials continuously passing through the feed pipe. At the same time, due to the centrifugal force generated when the diffusion frame rotates, the connecting plate disengages from the inner side of the diffusion frame through the telescopic rod, so that the connecting plate cleans the inner wall of the feed pipe, thus preventing wet materials from continuously passing through the feed pipe and adhering to the inner wall of the feed pipe, resulting in the phenomenon of material accumulation and hanging.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.
[0011] Example 1, using Figures 1 - 4 A pressure-reducing drying device for a drilling fluid filtrate reducer according to an embodiment of the present invention will be described as follows; As Figures 1 - 4 shown, a pressure-reducing drying device for a drilling fluid filtrate reducer of the present invention includes: A workbench 1, a drying tank 2 is fixedly connected to the top of the workbench 1, a vacuum pump 3 is fixedly connected to the top of the drying tank 2, a feeding component 4 is fixedly connected to the center of the top of the drying tank 2, a transmission component 5 is fixedly connected to the top of the workbench 1, and a discharging component 7 is fixedly connected to one side of the drying tank 2 away from the feeding component 4; A rotating component 6, which is used to turn the drilling fluid filtrate reducer in the drying tank 2. Both ends of the rotating component 6 are rotatably connected to the inside of the drying tank 2, and the output end of the transmission component 5 is fixedly connected to the rotating component 6; The rotating component 6 includes a rotating shaft 61. Both ends of the rotating shaft 61 are rotatably connected to the inside of the drying tank 2. One end of the rotating shaft 61 is fixedly connected to the output end of the transmission component 5. Rake teeth 62 are evenly arranged on the side of the rotating shaft 61, and a contact mechanism 63 is fixedly connected to the side of the rotating shaft 61 away from the rake teeth 62; The output end of the transmission component 5 drives the rotating shaft 61 to rotate in the drying tank 2, so that the rotating shaft 61 drives the rake teeth 62 to rotate in the inner cavity of the drying tank 2. The rake teeth 62 rotate slowly, continuously turning the drilling fluid filtrate reducer, making the drilling fluid filtrate reducer evenly heated and accelerating the evaporation of water. When the processing work is completed, the drilling fluid filtrate reducer in the drying tank 2 is discharged by opening the discharging component 7. At the same time, when the drilling fluid filtrate reducer in the drying tank 2 is slowly discharged through the discharging component 7, the transmission component 5 is adjusted, and the output end of the transmission component 5 drives the rotating shaft 61 to rotate rapidly. Thus, under the action of centrifugal force, the contact mechanism 63 moves away from the inside of the rotating shaft 61 and moves towards the inside of the drying tank 2. Through the rotation of the rotating shaft 61, the contact mechanism 63 cleans the inside of the drying tank 2, thus avoiding that after processing the materials in the drying tank 2, some residues of the drilling fluid filtrate reducer will remain on the inner wall of the drying tank 2 and dry and solidify in the drying tank 2, resulting in deterioration; The contact mechanism 63 includes a sliding rod 631. The side of the sliding rod 631 is slidably connected to the inner side of the rotating shaft 61. One end of the sliding rod 631 away from the rotating shaft 61 is fixedly connected to a sliding plate 632. Both sides of the sliding plate 632 are in contact with the inner side of the rotating shaft 61. A scraping plate 633 is fixedly connected to the side of the sliding plate 632. A contact plate 634 is fixedly connected to the side of the sliding plate 632 away from the scraping plate 633. A first spring 635 is sleeved on the sliding rod 631. One end of the first spring 635 is fixedly connected to the inner side of the rotating shaft 61, and the other end of the first spring 635 is fixedly connected to the sliding plate 632. When the filtrate reducer of the drilling fluid in the drying tank 2 is slowly discharged through the discharging component 7, by operating the transmission component 5, the output end of the transmission component 5 drives the rotating shaft 61 to rotate rapidly. Under the action of centrifugal force, the sliding rod 631 drives the sliding plate 632 to slide inside the rotating shaft 61, so that the sliding plate 632 drives the connecting plate 443 and the scraping plate 633 to move towards the inner wall of the drying tank 2, so that the scraping plate 633 scrapes the materials accumulated and solidified on the inner wall of the drying tank 2. At the same time, since the angle of the scraping plate 633 is smaller than the set angle of the contact plate 634, the contact plate 634 can contact and clean the solidified filtrate reducer of the drilling fluid on the inner wall of the drying tank 2, so as to prevent the scraping plate 633 from moving against the inner side of the drying tank 2, which will cause frictional damage to the inner side of the drying tank 2 and reduce the service life of the inner wall of the drying tank 2. At the same time, by continuing to rotate the rotating shaft 61, the contact plate 634 can move against the inner wall of the drying tank 2, so that the contact plate 634 can move against the place cleaned by the scraping plate 633. At the same time, since the material of the contact plate 634 is rubber material, it can prevent frictional damage to the inner wall of the drying tank 2 when cleaning and contacting the inner wall of the drying tank 2 for a long time; Embodiment 2, use Figures 5 - 7 The following is an explanation of a pressure-reducing drying device for a filtrate reducer of drilling fluid according to the present invention; As Figures 5 - 7 shown, a pressure-reducing drying device for a filtrate reducer of drilling fluid according to the present invention, on the basis of Embodiment 1; The discharging component 7 includes a discharging pipe 71. A bracket 72 is fixedly connected to the side of the discharging pipe 71. A first motor 73 is fixedly connected to one end of the discharging pipe 71. A spiral blade 74 is rotatably connected to the inner side of the discharging pipe 71. The output end of the first motor 73 is fixedly connected to the spiral blade 74. A discharging mechanism 76 is fixedly connected to the side of the discharging pipe 71 away from the bracket 72. A gate valve mechanism 75 is fixedly connected to the side of the discharging mechanism 76. The top of the discharging mechanism 76 is fixedly connected to the inner side of the drying tank 2. When the filtrate reducer in the drilling fluid in the drying tank 2 is processed, by opening the gate valve mechanism 75, the filtrate reducer in the drilling fluid in the drying tank 2 enters the discharging mechanism 76. At the same time, by turning on the first motor 73, the output end of the first motor 73 drives the spiral blade 74 to rotate in the discharging pipe 71, thereby driving the filtrate reducer in the drilling fluid to discharge, so as to prevent the filtrate reducer in the drilling fluid from deteriorating or sticking due to excessive temperature during the discharging process; The discharging mechanism 76 includes a discharging port 761. The bottom of the discharging port 761 is fixedly connected to the inner side of the discharging pipe 71. The top of the discharging port 761 is fixedly connected to the inner side of the drying tank 2. A fixing frame 762 is fixedly connected to the inner side of the discharging port 761. A guiding rod 763 is fixedly connected to the fixing frame 762. A limiting mechanism 764 is fixedly connected to the end of the guiding rod 763 away from the fixing frame 762. A moving frame 766 is slidably connected to the guiding rod 763. Scraping plates 767 are fixedly connected to both sides of the moving frame 766. A second spring 765 is sleeved on the guiding rod 763. The top of the second spring 765 is fixedly connected to the fixing frame 762. The other end of the second spring 765 is fixedly connected to the moving frame 766. The limiting mechanism 764 is arranged below the gate valve mechanism 75. When discharging the filtrate reducer in the drilling fluid in the drying tank 2, by opening the gate valve mechanism 75, the filtrate reducer in the drilling fluid in the drying tank 2 continuously enters the discharging pipe 71 through the discharging port 761, so that the filtrate reducer during discharging impacts the moving frame 766, thereby causing the moving frame 766 to drive the scraping plates 767 to move downward on the guiding rod 763. At the same time, when discharging, when the impact speed of the material on the moving frame 766 is less than the tensile force of the second spring 765, the moving frame 766 moves upward through the tensile force of the first spring 635, so that the moving frame 766 drives the scraping plates 767 to clean the inner side of the discharging port 761, so as to avoid the phenomenon that the material will be retained on the inner side of the discharging port 761 due to excessive temperature when the material is discharged. Thus, the inner wall of the discharging port 761 is cleaned by the scraping plates 767. At the same time, when the moving frame 766 moves toward the limiting mechanism 764 through the reset of the second spring 765, the limiting mechanism 764 can buffer the moving frame 766; The limiting mechanism 764 includes a limiting frame 7641. The side of the limiting frame 7641 is fixedly connected to the inner side of the discharge port 761. A through hole 7642 is provided in the middle of the limiting frame 7641. The inner side of the through hole 7642 is fixedly connected to the side of the guiding rod 763. A buffer frame 7643 is fixedly connected to one side of the limiting frame 7641 close to the moving frame 766. A third spring 7644 is fixedly connected to the inner side of the buffer frame 7643. The other end of the third spring 7644 is fixedly connected to a buffer block 7645. When the moving frame 766 is driven by the reset of the second spring 765 to move towards the limiting frame 7641, the side of the moving frame 766 is in contact with the buffer frame 7643. By providing a buffer block 7645 in the middle of the inner side of the buffer frame 7643, and the material of the buffer block 7645 is rubber material. Thus, when the moving frame 766 is in contact and squeezed with the buffer block 7645, the buffer block 7645 simultaneously performs a buffering operation through the third spring 7644 to buffer the impact during the reset of the moving frame 766, thereby avoiding excessive impact force between the moving frame 766 and the limiting frame 7641, which may cause impact damage to the moving frame 766 and the scraping plate 767. At the same time, through the impact vibration between the moving frame 766 and the buffer frame 7643, the remaining material adhering to the scraping plate 767 can be shaken off, thereby preventing the remaining material of the drilling fluid filtrate reducer from adhering to the scraping plate 767; Example 3, usage Figures 8 - 9 The following description is made for a decompression drying device for a drilling fluid filtrate reducer according to the present invention; As Figures 8 - 9 shown, a decompression drying device for a drilling fluid filtrate reducer according to the present invention, on the basis of Example 1; The feeding component 4 includes a feeding pipe 41. The bottom of the feeding pipe 41 is fixedly connected to the inner side of the drying tank 2. An installation frame 42 is fixedly connected to the inner side of the feeding pipe 41. A second motor 43 is fixedly connected to the top of the installation frame 42. A diffusion mechanism 44 is rotatably connected to the side of the installation frame 42. The output end of the second motor 43 is fixedly connected to the diffusion mechanism 44. When adding the drilling fluid filtrate reducer into the drying tank 2, the drilling fluid filtrate reducer continuously enters the drying tank 2. By turning on the second motor 43, the output end of the second motor 43 drives the diffusion mechanism 44 to rotate in the feeding pipe 41, so that the diffusion mechanism 44 diffuses the continuously passing material in the feeding pipe 41, thereby avoiding the phenomenon of accumulation and blockage during the feeding of the drilling fluid filtrate reducer due to the relatively wet nature of the drilling fluid filtrate reducer itself; The diffusion mechanism 44 includes a connecting shaft 441. The top of the connecting shaft 441 is fixedly connected to the output end of the second motor 43. Both sides of the connecting shaft 441 are fixedly connected with diffusion frames 442. The inner sides of the diffusion frames 442 are fixedly connected with telescopic rods 444. One end of the telescopic rod 444 away from the diffusion frame 442 is fixedly connected with a connecting plate 443. The side of the connecting plate 443 is in contact with the inner side of the diffusion frame 442. A fourth spring 445 is sleeved on the telescopic rod 444. One end of the fourth spring 445 is fixedly connected with the connecting plate 443, and the other end of the fourth spring 445 is fixedly connected with the inner side of the diffusion frame 442. When the output end of the second motor 43 drives the connecting shaft 441 to rotate, the diffusion frames 442 are driven by the connecting shaft 441 to diffuse the materials continuously passing through the feed pipe 41. At the same time, due to the centrifugal force generated when the diffusion frames 442 rotate, the connecting plate 443 is separated from the inner side of the diffusion frame 442 through the telescopic rod 444, so that the connecting plate 443 cleans the inner wall of the feed pipe 41, thereby preventing wet materials from continuously passing through the feed pipe 41 and adhering to the inner wall of the feed pipe 41, resulting in the phenomenon of material accumulation and hanging; The specific working process is as follows: During operation, the drilling fluid filtration reducer is placed in the drying tank 2 through the feeding component 4. The output end of the transmission component 5 drives the rotating component 6 to rotate in the drying tank 2, thereby turning the drilling fluid filtration reducer in the drying tank 2. The air in the drying tank 2 is pumped out by devices such as the vacuum pump 3, so that a certain degree of vacuum state is formed in the drying tank 2, reducing the air pressure in the drying tank 2. The equipment is equipped with a heating device, such as a heating pipe, etc., to heat the drilling fluid filtration reducer placed in the drying tank 2. The heat is transferred to the filtration reducer, enabling the water in the filtration reducer to obtain sufficient energy to overcome the intermolecular force and transform from a liquid state to a gaseous state. Since water can boil and vaporize at a relatively low temperature, the drying of the drilling fluid filtration reducer can be achieved at a relatively low temperature, avoiding the damage to the performance of the filtration reducer caused by high temperature. The water vapor in the drying tank 2 will be continuously pumped out of the drying tank 2 by the vacuum pump 3, so that a relatively low water vapor partial pressure is always maintained in the drying tank 2, creating favorable conditions for the continuous evaporation of the water in the filtration reducer. In this way, water continuously evaporates from the filtration reducer and is discharged until the water content in the filtration reducer is reduced to the required level. When the vacuum drying work is completed, the dried drilling fluid filtration reducer in the drying tank 2 is discharged by opening the discharging component 7; The output end of the transmission component 5 drives the rotating shaft 61 to rotate in the drying tank 2, so that the rotating shaft 61 drives the rake teeth 62 to rotate in the inner cavity of the drying tank 2. The rake teeth 62 rotate slowly, continuously turning the filtrate reducer of the drilling fluid, making the filtrate reducer of the drilling fluid evenly heated and accelerating the evaporation of water. When the processing work is completed, the filtrate reducer of the drilling fluid in the drying tank 2 is discharged by opening the discharging component 7. At the same time, when the filtrate reducer of the drilling fluid in the drying tank 2 is slowly discharged through the discharging component 7, the transmission component 5 is adjusted. The output end of the transmission component 5 drives the rotating shaft 61 to rotate rapidly. Thus, under the action of centrifugal force, the contact mechanism 63 moves away from the inner side of the rotating shaft 61 and moves towards the inner side of the drying tank 2. By the rotation of the rotating shaft 61, the contact mechanism 63 cleans the inner side of the drying tank 2, so as to avoid that after processing the materials in the drying tank 2, some residues of the filtrate reducer of the drilling fluid will remain on the inner wall of the drying tank 2 and solidify in the drying tank 2, resulting in deterioration; When the filtrate reducer of the drilling fluid in the drying tank 2 is slowly discharged through the discharging component 7, by operating the transmission component 5, the output end of the transmission component 5 drives the rotating shaft 61 to rotate rapidly. Under the action of centrifugal force, the sliding rod 631 drives the sliding plate 632 to slide inside the rotating shaft 61, so that the sliding plate 632 drives the connecting plate 443 and the scraper 633 to move towards the inner wall of the drying tank 2, so that the scraper 633 scrapes the materials piled up and solidified on the inner wall of the drying tank 2. At the same time, since the angle of the scraper 633 is smaller than the set angle of the contact plate 634, the contact plate 634 can contact and clean the solidified filtrate reducer of the drilling fluid on the inner wall of the drying tank 2, so as to avoid the scraper 633 moving against the inner side of the drying tank 2, which will cause frictional damage to the inner side of the drying tank 2 and reduce the service life of the inner wall of the drying tank 2. At the same time, by the continuous rotation of the rotating shaft 61, the contact plate 634 can move against the inner wall of the drying tank 2, so that the contact plate 634 can move against the place cleaned by the scraper 633. At the same time, since the material of the contact plate 634 is rubber material, it can avoid frictional damage to the inner wall of the drying tank 2 when cleaning and contacting the inner wall of the drying tank 2 for a long time; After the filtrate reducer of the drilling fluid in the drying tank 2 is processed, by opening the gate valve mechanism 75, the filtrate reducer of the drilling fluid in the drying tank 2 enters the discharging mechanism 76. At the same time, by turning on the first motor 73, the output end of the first motor 73 drives the spiral blade 74 to rotate in the discharging pipe 71, and then drives the filtrate reducer of the drilling fluid to be discharged, so as to prevent the filtrate reducer of the drilling fluid from deteriorating or sticking due to too high temperature during the discharging process; When discharging the filtrate reducer of the drilling fluid in the drying tank 2, by opening the gate valve mechanism 75, the filtrate reducer of the drilling fluid in the drying tank 2 continuously enters the discharge pipe 71 through the discharge port 761, so that the filtrate reducer of the drilling fluid during discharging impacts the moving frame 766, thereby causing the moving frame 766 to drive the scraping plate 767 to move downward on the guide rod 763. At the same time, when discharging, when the impact speed of the material on the moving frame 766 is less than the tensile force of the second spring 765, the moving frame 766 is driven by the tensile force of the first spring 635, so that the first spring 635 drives the moving frame 766 to move upward, thereby causing the moving frame 766 to drive the scraping plate 767 to clean the inner side of the discharge port 761, thus avoiding the phenomenon that the material will hang on the inner side of the discharge port 761 due to too high temperature during the discharging of the material. Thus, the inner wall of the discharge port 761 is cleaned by the scraping plate 767. At the same time, when the moving frame 766 is driven by the reset of the second spring 765 to move towards the limiting mechanism 764, the limiting mechanism 764 can buffer the moving frame 766; When the moving frame 766 is driven by the reset of the second spring 765 to move towards the limiting frame 7641, the side surface of the moving frame 766 is in contact with the buffer frame 7643. A buffer block 7645 is arranged in the middle of the inner side of the buffer frame 7643, and the material of the buffer block 7645 is rubber material. Thus, when the moving frame 766 is in contact and squeezed with the buffer block 7645, the buffer block 7645 simultaneously buffers the reset impact of the moving frame 766 through the buffer work of the third spring 7644, thereby avoiding too large impact force between the moving frame 766 and the limiting frame 7641, which may cause impact damage to the moving frame 766 and the scraping plate 767. At the same time, through the impact vibration between the moving frame 766 and the buffer frame 7643, the remaining material of the material adhering to the scraping plate 767 can be shaken off, thus avoiding the remaining material of the filtrate reducer of the drilling fluid from adhering to the scraping plate 767; When adding the filtrate reducer of the drilling fluid into the drying tank 2, the filtrate reducer of the drilling fluid continuously enters the drying tank 2. By turning on the second motor 43, the output end of the second motor 43 drives the diffusion mechanism 44 to rotate in the feed pipe 41, so that the diffusion mechanism 44 diffuses the material continuously passing through the feed pipe 41, thus avoiding the phenomenon that the filtrate reducer of the drilling fluid accumulates and blocks during the feeding process due to the relatively wet nature of the filtrate reducer of the drilling fluid itself; When the output end of the second motor 43 drives the connecting shaft 441 to rotate, the connecting shaft 441 drives the diffusion frame 442 to perform diffusion work on the materials continuously passing through the feed pipe 41. At the same time, due to the centrifugal force generated when the diffusion frame 442 rotates, the connecting plate 443 disengages from the inner side of the diffusion frame 442 through the telescopic rod 444, so that the connecting plate 443 cleans the inner wall of the feed pipe 41, thus preventing wet materials from continuously passing through the feed pipe 41 and adhering to the inner wall of the feed pipe 41, resulting in the phenomenon of material accumulation and hanging.
