Abstract
Description
Technical Field
[0001] The invention relates to the technical field of industrial mixed oil deacidification, and in particular to a stirring process and a stirring device for industrial mixed oil deacidification. Background Art
[0002] The free fatty acids in industrial blended oils and fats can have many adverse effects on the quality of the oils and fats. For example, it will increase the acid value of the oils and fats, causing the oils and fats to produce a pungent odor, and will reduce the oxidative stability of the oils and fats, making the oils and fats more susceptible to deterioration. In addition, oils and fats with high acid values may affect the taste and shelf life of food when used in food processing. When used in industrial production (such as lubricating oils, biodiesel manufacturing, etc.), they will also have a negative impact on the performance and quality of the products. Therefore, deacidification is a key step in the refining process of industrial blended oils and fats, which can effectively improve the quality and applicability of oils and fats.
[0003] During the soap stock separation process, since the separation between soap stock and grease cannot be completely thorough, a small amount of neutral oil may adhere to the inner wall of the device after the stirring work is completed. If this part of neutral oil is not cleaned in time, it may oxidize and deteriorate after a long time, affecting the cleanliness of the device and the subsequent grease deacidification effect. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting the following technical solutions: a stirring process and stirring device for deacidification of industrial mixed oils; A stirring process for deacidification of industrial mixed oils and fats comprises the following steps: S1: Equipment inspection and preheating: Check whether the stirring equipment is operating normally, including whether the agitator rotates smoothly and whether the motor is normal. At the same time, preheat the deacidification reaction vessel. Generally, preheat the oil to about 50-60℃. This can reduce the viscosity of the oil and facilitate subsequent stirring and reaction. S2: Alkali solution preparation: The concentration and amount of alkali solution required are calculated based on the acid value of the oil. Sodium hydroxide solution is usually used as an alkali refining agent. Sodium hydroxide solid is dissolved in an appropriate amount of water to prepare an alkali solution of a certain concentration. The prepared alkali solution needs to be filtered to remove impurities and insoluble particles. S3: Stirring: The oil is fed into the tank through the feed component, the motor is turned on, and stirring is started at a low speed. Then, the prepared alkali solution is slowly added to the oil. The alkali solution addition process generally lasts for 10-20 minutes to ensure that the alkali solution is evenly dispersed in the oil. S4: Increase stirring speed: After adding the alkali solution, gradually increase the speed of the stirring component, usually to 100-300 revolutions per minute, so that the oil and alkali solution are fully mixed and the neutralization reaction is accelerated. During this process, the reaction situation should be closely observed to prevent excessive emulsification of the oil; S5: When the neutralization reaction is nearly complete, gradually reduce the speed of the stirrer and stir at a speed of 30-60 revolutions per minute to allow the generated soap stock to fully settle; A tank body, wherein the bottom of the tank body is fixedly connected to a fixing frame, the side of the tank body is fixedly connected to a control component, the axis of the bottom of the tank body is fixedly connected to a motor, the side of the tank body is fixedly connected to a feeding component, and the side of the tank body away from the feeding component is fixedly connected to a discharging component; A stirring member, which is used to stir the industrial mixed oil in the tank body, wherein both ends of the stirring member are rotatably connected to the inner side of the tank body, and the output end of the motor is fixedly connected to the bottom of the stirring member; The stirring component includes a stirring rod, and the upper and lower ends of the stirring rod are rotatably connected to the inner side of the tank body, the output end of the motor is fixedly connected to the bottom of the stirring rod, the side of the stirring rod is fixedly connected to a stirring blade, the side of the stirring rod away from the stirring blade is fixedly connected to a stirring block, and the side of the stirring blade is fixedly connected to a cleaning mechanism; when the material enters the tank body, by turning on the motor, the output end of the motor drives the stirring blade and the stirring block through the stirring rod to rotate in the tank body, and the grease and fat in the tank body are fully mixed and stirred. After the stirring work is completed, the grease in the tank body is discharged through the discharging component. Since the separation between the soap stock and the grease cannot be completely thorough, a small amount of neutral oil may adhere to the inner wall of the device after the stirring work is completed. If this part of the neutral oil is not cleaned in time, it may oxidize and deteriorate after a long time. By turning on the motor, the stirring rod is driven by the output end of the motor to rotate rapidly in the tank body, so that the cleaning mechanism cleans the inner wall of the tank body, thereby preventing a small amount of neutral oil from adhering to the inner wall of the tank body for a long time, thereby causing deterioration; The cam is secured to the inner wall of the sliding groove and is adapted to engage the sliding plate, the end of which is fixed to the inner wall of the sliding groove and engages with the outer wall of the sliding plate. The movable scraper and the rubber plate move toward the inner wall of the tank body. By bending the rubber plate at a greater angle than the scraper on the connecting plate, when the stirring rod rotates rapidly, the connecting plate drives the connecting plate out of the sliding groove due to the action of centrifugal force, and can first collide with the inner wall of the tank body through the rubber plate. At the same time, the rubber material of the rubber plate can reduce the impact force between the rubber plate and the inner wall of the tank body, so that the stirring rod drives the scraper to clean the inner wall of the tank body through the connecting plate. At the same time, the scraper can scrape off the grease dried on the inner wall of the tank body. At the same time, because the bending angle of the rubber plate is greater than the scraper, the rubber plate can be in contact with the inner wall of the tank body, thereby avoiding scratches and damage to the inner wall of the tank body when cleaning the inner wall of the tank body for a long time, thereby reducing the service life of the tank body. Preferably, the feeding component includes a feeding pipe, the side surface of the feeding pipe is fixedly connected to the inner side of the tank body, the side of the feeding pipe away from the tank body is fixedly connected to a mesh plate, the side of the mesh plate is fixedly connected to a telescopic rod, a second spring is sleeved on the telescopic rod, one end of the second spring is fixedly connected to the mesh plate, the other end of the second spring is fixedly connected to the bracket, the end of the telescopic rod away from the mesh plate is fixedly connected to the bracket, and the side of the bracket close to the mesh plate is fixedly connected to an ejection mechanism; when deacidifying and stirring industrial grease, since industrial mixed grease comes from a wide range of sources, it may contain various impurities, such as mechanical impurities, solid particles and colloidal impurities. If these impurities are not filtered, they will have an adverse effect on the deacidification and stirring process. Many adverse effects, after the external pipe is fixedly connected to the feed pipe, the grease continues to enter the tank body through the feed pipe, and a mesh plate is provided on the inner side of the feed pipe to filter the particulate impurities in the grease. At the same time, when the industrial grease continues to pass through the feed pipe, the impact of the grease causes the bracket to be driven by the telescopic rod to move to the side away from the mesh plate. At the same time, when the mesh plate filters the working grease, when the impurities in the grease cause the mesh plate to be blocked, the impact force of the grease in the feed pipe is less than the tensile force of the second spring, so that the bracket drives the ejection mechanism to move toward the mesh plate, thereby ejecting the impurities stuck in the mesh of the mesh plate, thereby ensuring the normal filtering work of the mesh plate; The cam is fixedly provided with a toothed plate, and the cam is fixedly provided with a toothed plate, and the toothed plate is fixedly provided with a toothed plate. The needle ejects the impurities stuck in the mesh of the mesh plate. At the same time, when the extrusion force between the ejector pin and the impurities stuck in the mesh of the mesh plate is greater than the tensile force of the third spring, the ejector pin moves in the slot through the moving rod and the moving block. At the same time, the buffering force of the third spring is used to prevent the extrusion force of the impurities stuck in the mesh of the mesh plate from being too large when the ejector pin is performing the blockage clearing work, thereby causing extrusion damage to the ejector pin. At the same time, when the grease feeding work is completed, the bracket is driven to move toward the mesh plate by the reset stretching of the third spring, and the ejector pin continues to pass through the mesh of the mesh plate, so that the ejector pin drives the extrusion plate to clean and scratch the inner side of the mesh of the mesh plate, thereby preventing the grease residue from drying on the inner wall of the mesh hole. If the cleaning work is not performed for a long time, the dry solid will accumulate on the inner wall of the mesh hole, thereby causing the grease feeding speed to slow down. Preferably, the discharging component includes a discharging pipe, the discharging pipe is installed with a gate valve mechanism, the side of the discharging pipe is fixedly connected to the inner side of the tank body, the end of the discharging pipe away from the tank body is fixedly connected to a baffle, the inner side of the discharging pipe is fixedly connected to a buffer mechanism, the side of the baffle close to the buffer mechanism is fixedly connected to a guide rod, the side of the baffle is fixedly connected to a fourth spring, and the end of the fourth spring away from the baffle is fixedly connected to a contact mechanism; after the grease in the tank body is mixed, the gate valve mechanism is operated to allow the grease in the discharging pipe to be discharged. The discharging operation is performed, and at the same time, the grease flows out through the discharging pipe. The impact force of the grease causes the contact mechanism to pull the fourth spring to move on the guide rod. At the same time, after the grease is discharged, when the impact force of the grease through the discharging pipe is less than the tensile force of the fourth spring, the contact mechanism is pulled by the reset of the fourth spring to move on the guide rod. At the same time, the inner wall of the discharging pipe is cleaned by the contact mechanism. At the same time, when the contact mechanism is reset by the stretching of the fourth spring, the contact mechanism and the buffer mechanism are used to buffer the impact, thereby avoiding damage to the contact mechanism. Preferably, the contact mechanism includes a contact frame, a side surface of the contact frame is fixedly connected to an end of the fourth spring away from the baffle, and both sides of the contact frame are fixedly connected to a contact plate, and a through hole is opened on the side surface of the contact frame, and the inner side of the through hole is slidably connected to the side surface of the guide rod; when the grease is discharged, when the impact force of the grease passing through the discharge pipe is less than the tensile force of the fourth spring, the contact frame is pulled by the reset of the fourth spring to move on the guide rod, so that the contact frame drives the contact plate to clean the inner wall of the discharge pipe, thereby avoiding a large amount of grease from remaining on the inner wall of the discharge pipe after a large amount of grease flows out through the discharge pipe, thereby causing the grease to dry on the inner wall of the discharge pipe; Preferably, the buffer mechanism includes a buffer frame, a through hole is provided on the side of the buffer frame, the side of the through hole is fixedly connected to the side of the guide rod, the side of the buffer frame is fixedly connected to the inner wall of the discharge pipe, the side of the buffer frame close to the contact frame is fixedly connected with a buffer plate, and the middle part of the side of the buffer plate is fixedly connected with a buffer block; when the contact frame is reset by the stretching of the fourth spring, the contact frame collides with the buffer frame, and a buffer block is provided in the middle of the buffer plate, and the material of the buffer block is rubber material, so as to avoid excessive impact force between the contact frame and the buffer plate when the contact plate is reset by the stretching of the fourth spring, thereby causing damage to the contact plate and the contact frame, and at the same time, when the contact frame and the buffer block perform buffering collision, the grease adhering to the contact plate can be shaken off by the vibration force generated by the collision.
[0005] The beneficial effects of the present invention are as follows: 1. The present invention provides a cleaning mechanism, and after the grease in the tank body is discharged, the motor is turned on, and the output end of the motor drives the stirring rod to rotate rapidly in the tank body. Due to the action of centrifugal force, the connecting plate slides out of the sliding groove through the sliding rod, thereby driving the scraper and the rubber plate to move toward the inner wall of the tank body through the connecting plate. By bending the rubber plate on the connecting plate at a greater angle than the scraper, when the stirring rod rotates rapidly, the connecting plate is driven by the centrifugal force to disengage from the sliding groove, and can first collide with the inner wall of the tank body through the rubber plate, and at the same time, the rubber material of the rubber plate reduces the impact force between the stirring rod and the inner wall of the tank body, so that the stirring rod drives the scraper to clean the inner wall of the tank body through the connecting plate.
[0006] 2. The present invention sets a feeding component. When deacidifying and stirring industrial grease, since industrial mixed grease comes from a wide range of sources, it may contain various impurities, such as mechanical impurities, solid particles and colloidal impurities. If these impurities are not filtered, they will have many adverse effects on the deacidification and stirring process. After being fixedly connected to the feed pipe through an external pipe, the grease continues to enter the tank body through the feed pipe. By setting a mesh plate on the inner side of the feed pipe, the particulate impurities in the grease are filtered.
[0007] 3. The present invention provides an ejection mechanism. When the impact force of grease in the feed pipe is less than the tensile force of the second spring, the bracket drives the ejection rod to move toward the mesh plate, so that the ejection rod drives the ejector pin to eject impurities stuck in the mesh of the mesh plate. At the same time, when the extrusion force between the ejector pin and the impurities stuck in the mesh of the mesh plate is greater than the tensile force of the third spring, the ejector pin moves in the slot through the moving rod and the moving block. At the same time, the buffering force of the third spring is used to prevent the extrusion force of impurities stuck in the mesh of the mesh plate from being too large when the ejector pin is performing the blockage clearing work, thereby causing extrusion damage to the ejector pin.
[0008] 4. The present invention provides a discharge component, and after mixing the grease in the tank body, operates the gate valve mechanism to discharge the grease in the discharge pipe, and at the same time, the grease flows out through the discharge pipe. The impact force of the grease causes the contact mechanism to pull the fourth spring to move on the guide rod. At the same time, after the grease is discharged, when the impact force of the grease through the discharge pipe is less than the tensile force of the fourth spring, the contact mechanism is pulled by the reset of the fourth spring to move on the guide rod, and at the same time, the inner wall of the discharge pipe is cleaned by the contact mechanism. At the same time, when the contact mechanism is reset by the stretching of the fourth spring, the contact mechanism and the buffer mechanism are used to buffer the collision, thereby avoiding damage to the contact mechanism.

[0010] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.
[0011] Example 1: Use Figure 1 The stirring process for deacidification of industrial mixed oils according to one embodiment of the present invention is described as follows; like Figure 1 The present invention shows that a stirring process for deacidification of industrial mixed oils and fats comprises the following steps: S1: Equipment inspection and preheating: Check whether the stirring equipment is operating normally, including whether the agitator rotates smoothly and whether the motor is normal. At the same time, preheat the deacidification reaction vessel. Generally, preheat the oil to about 50-60℃. This can reduce the viscosity of the oil and facilitate subsequent stirring and reaction. S2: Alkali solution preparation: The concentration and amount of alkali solution required are calculated based on the acid value of the oil. Sodium hydroxide solution is usually used as an alkali refining agent. Sodium hydroxide solid is dissolved in an appropriate amount of water to prepare an alkali solution of a certain concentration. The prepared alkali solution needs to be filtered to remove impurities and insoluble particles. S3: Stirring: The oil is fed into the tank through the feed component, the motor is turned on, and stirring is started at a low speed. Then, the prepared alkali solution is slowly added to the oil. The alkali solution addition process generally lasts for 10-20 minutes to ensure that the alkali solution is evenly dispersed in the oil. S4: Increase stirring speed: After adding the alkali solution, gradually increase the speed of the stirring component, usually to 100-300 revolutions per minute, so that the oil and alkali solution are fully mixed and the neutralization reaction is accelerated. During this process, the reaction situation should be closely observed to prevent excessive emulsification of the oil; S5: When the neutralization reaction is nearly complete, gradually reduce the speed of the stirrer and stir at a speed of 30-60 revolutions per minute to allow the generated soap stock to fully settle; Example 2: Use Figure 2-Figure 5 A stirring device for deacidification of industrial mixed oils according to one embodiment of the present invention is described as follows; like Figure 2-Figure 5 The present invention shows a stirring device for deacidification of industrial mixed oils, comprising: The tank body 1 has a fixing frame 2 fixedly connected to the bottom of the tank body 1, a control component 5 fixedly connected to the side of the tank body 1, a motor 7 fixedly connected to the axis of the bottom of the tank body 1, a feeding component 3 fixedly connected to the side of the tank body 1, and a discharging component 4 fixedly connected to the side of the tank body 1 away from the feeding component 3; A stirring member 6 is used to stir the industrial mixed oil in the tank body 1. Both ends of the stirring member 6 are rotatably connected to the inner side of the tank body 1, and the output end of the motor 7 is fixedly connected to the bottom of the stirring member 6; The stirring component 6 includes a stirring rod 61, the upper and lower ends of the stirring rod 61 are rotatably connected to the inner side of the tank body 1, the output end of the motor 7 is fixedly connected to the bottom of the stirring rod 61, the side of the stirring rod 61 is fixedly connected to a stirring blade 62, the side of the stirring rod 61 away from the stirring blade 62 is fixedly connected to a stirring block 63, and the side of the stirring blade 62 is fixedly connected to a cleaning mechanism 64; when the material enters the tank body 1, by turning on the motor 7, the output end of the motor 7 drives the stirring blade 62 and the stirring block 63 through the stirring rod 61 to rotate in the tank body 1, and the grease and oil in the tank body are fully mixed and stirred. When the stirring work is completed, the grease in the tank body 1 is discharged through the discharging component 4. Since the separation between the soap stock and the grease cannot be completely thorough, a small amount of neutral oil may adhere to the inner wall of the device after the stirring work is completed. If this part of the neutral oil is not cleaned in time, it may be oxidized and deteriorated after a long time. By turning on the motor 7, the stirring rod 61 is driven by the output end of the motor 7 to rotate rapidly in the tank body 1, so that the cleaning mechanism 64 cleans the inner wall of the tank body 1, thereby preventing a small amount of neutral oil from adhering to the inner wall of the tank body 1 for a long time, thereby causing deterioration. The cleaning mechanism 64 includes a sliding groove 641, which is opened on the side of the stirring blade 62, and a sliding rod 642 is slidably connected to the inner side of the sliding groove 641. The end of the sliding rod 642 away from the inner side of the sliding groove 641 is fixedly connected to the connecting plate 643, and the side of the connecting plate 643 is slidably connected to the inner side of the sliding groove 641. A first spring 644 is sleeved on the sliding rod 642, one end of the first spring 644 is fixedly connected to the connecting plate 643, and the other end of the first spring 644 is fixedly connected to the inner wall of the sliding groove 641. A rubber plate 645 is fixedly connected to the side of the connecting plate 643, and a scraper 646 is fixedly connected to the side of the connecting plate 643 away from the rubber plate 645. After the grease in the tank body 1 is discharged, the motor 7 is turned on and the stirring rod 61 is driven to rotate rapidly in the tank body 1 through the output end of the motor 7. Under the action of centrifugal force, the connecting plate 643 slides out of the sliding groove 641 through the sliding rod 642, thereby driving the scraper 646 through the connecting plate 643 The plate 646 and the rubber plate 645 move toward the inner wall of the tank body 1. By bending the rubber plate 645 at a greater angle than the scraper plate 646 on the connecting plate 643, when the stirring rod 61 rotates rapidly, the connecting plate 643 drives the connecting plate 643 out of the sliding groove 641 by the action of centrifugal force, and can first collide with the inner wall of the tank body 1 through the rubber plate 645. At the same time, the rubber material of the rubber plate 645 can reduce the impact force between the rubber plate 645 and the inner wall of the tank body 1, thereby The stirring rod 61 drives the scraper 646 through the connecting plate 643 to clean the inner wall of the tank body 1. At the same time, the scraper 646 can scrape off the grease that has dried on the inner wall of the tank body 1. At the same time, because the bending angle of the rubber plate 645 is greater than that of the scraper 646, the rubber plate 645 can contact the inner wall of the tank body 1, thereby preventing the inner wall of the tank body 1 from being scratched and damaged when cleaning the inner wall of the tank body 1 for a long time, thereby reducing the service life of the tank body 1. Example 3: Use Figure 6-Figure 7 The stirring device for deacidification of industrial mixed grease of the present invention is described as follows; like Figure 6-Figure 7 The present invention shows a stirring device for deacidification of industrial mixed oils and fats, based on the first embodiment; The feeding component 3 includes a feeding pipe 31, the side of the feeding pipe 31 is fixedly connected to the inner side of the tank body 1, the side of the feeding pipe 31 away from the tank body 1 is fixedly connected to the mesh plate 32, the side of the mesh plate 32 is fixedly connected to the telescopic rod 33, a second spring 36 is sleeved on the telescopic rod 33, one end of the second spring 36 is fixedly connected to the mesh plate 32, the other end of the second spring 36 is fixedly connected to the bracket 34, the end of the telescopic rod 33 away from the mesh plate 32 is fixedly connected to the bracket 34, and the side of the bracket 34 close to the mesh plate 32 is fixedly connected to the ejection mechanism 35; when deacidifying and stirring industrial grease, since industrial mixed grease comes from a wide range of sources, it may contain various impurities, such as mechanical impurities, solid particles and colloidal impurities. If these impurities are not filtered, they will have many adverse effects on the deacidification and stirring process. After the external pipe is fixedly connected to the feed pipe 31, the grease continues to enter the tank body 1 through the feed pipe 31. By providing a mesh plate 32 on the inner side of the feed pipe 31, particulate impurities in the grease are filtered. At the same time, when the industrial grease continues to pass through the feed pipe 31, the impact of the grease causes the bracket 34 to move to the side away from the mesh plate 32 through the telescopic rod 33. At the same time, when the mesh plate 32 filters the working grease, when impurities in the grease cause clogging of the mesh plate 32, the impact force of the grease in the feed pipe 31 is less than the tensile force of the second spring 36, so that the bracket 34 drives the ejection mechanism 35 to move toward the mesh plate 32, thereby ejecting impurities stuck in the mesh of the mesh plate 32, thereby ensuring the normal filtering of the mesh plate 32. The ejection mechanism 35 includes an ejection rod 351, the side of the ejection rod 351 is fixedly connected to the bracket 34, a notch 352 is provided on the side of the ejection rod 351, a moving block 353 is slidably connected to the inner side of the notch 352, and a moving rod 354 is fixedly connected to the side of the moving block 353, and a third spring 358 is sleeved on the moving rod 354.

The inner side of the sleeve 355 is slidably connected to the side of the ejector rod 351, and the side of the sleeve 355 away from the ejector pin 357 is fixedly connected to the extrusion plate 356; when the impact force of the grease in the feed pipe 31 is less than the tensile force of the second spring 36, the bracket 34 drives the ejector rod 351 to move toward the mesh plate 32, so that the ejector rod 35 1 drives the ejector pin 357 to eject the impurities stuck in the mesh of the mesh plate 32. At the same time, when the extrusion force between the ejector pin 357 and the impurities stuck in the mesh of the mesh plate 32 is greater than the tensile force of the third spring 358, the ejector pin 357 moves in the slot 352 through the moving rod 354 and the moving block 353. At the same time, the buffering force of the third spring 358 is used to prevent the ejector pin 357 from being squeezed too much by the impurities stuck in the mesh of the mesh plate 32 when the ejector pin 357 is clearing the blockage. At the same time, when the grease feeding work is completed, the bracket 34 is moved toward the mesh plate 32 by the reset stretching of the third spring 358, and the ejector rod 351 continues to pass through the mesh of the mesh plate 32, so that the ejector rod 351 drives the extrusion plate 356 to clean and scrape the inner side of the mesh of the mesh plate 32, thereby preventing grease residue from drying on the inner wall of the mesh. If the cleaning work is not performed for a long time, the dry residue will accumulate on the inner wall of the mesh, thereby slowing down the grease feeding speed; Example 4: Use Figures 8-10 The stirring device for deacidification of industrial mixed grease of the present invention is described as follows; like Figures 8-10 The present invention shows a stirring device for deacidification of industrial mixed oils and fats, based on the first embodiment; The discharge component 4 includes a discharge pipe 41, and the discharge pipe 41 is provided with a gate valve mechanism 42. The side of the discharge pipe 41 is fixedly connected to the inner side of the tank body 1, and the end of the discharge pipe 41 away from the tank body 1 is fixedly connected to a baffle 43, and the inner side of the discharge pipe 41 is fixedly connected to a buffer mechanism 47. The side of the baffle 43 close to the buffer mechanism 47 is fixedly connected to a guide rod 44, and the side of the baffle 43 is fixedly connected to a fourth spring 45, and the end of the fourth spring 45 away from the baffle 43 is fixedly connected to a contact mechanism 46. After the grease in the tank body 1 is mixed, the gate valve mechanism 42 is operated to discharge the grease in the discharge pipe 41. At the same time, the grease flows out through the discharge pipe 41, and the impact force of the grease causes the contact mechanism 46 to pull the fourth spring 45 to move on the guide rod 44. At the same time, after the grease is discharged, when the impact force of the grease passing through the discharge pipe 41 is less than the tensile force of the fourth spring 45, the contact mechanism 46 is pulled by the reset of the fourth spring 45 to move on the guide rod 44. At the same time, the inner wall of the discharge pipe 41 is cleaned by the contact mechanism 46. At the same time, when the contact mechanism 46 is reset by the stretching of the fourth spring 45, the contact mechanism 46 and the buffer mechanism 47 buffer the collision, thereby avoiding damage to the contact mechanism 46. The contact mechanism 46 includes a contact frame 461, a side surface of which is fixedly connected to an end of the fourth spring 45 away from the baffle 43, and contact plates 463 are fixedly connected to both sides of the contact frame 461. A through hole 462 is provided on the side surface of the contact frame 461, and the inner side of the through hole 462 is slidably connected to the side surface of the guide rod 44; when the grease is discharged, when the impact force of the grease passing through the discharge pipe 41 is less than the tensile force of the fourth spring 45, the contact frame 461 is pulled by the reset of the fourth spring 45 to move on the guide rod 44, so that the contact frame 461 drives the contact plate 463 to clean the inner wall of the discharge pipe 41, thereby preventing a large amount of grease from remaining on the inner wall of the discharge pipe 41 after a large amount of grease flows out through the discharge pipe 41, thereby causing the grease to dry on the inner wall of the discharge pipe 41; The buffer mechanism 47 includes a buffer frame 471, a through hole 472 is provided on the side of the buffer frame 471, the side of the through hole 472 is fixedly connected to the side of the guide rod 44, the side of the buffer frame 471 is fixedly connected to the inner wall of the discharge pipe 41, and a buffer plate 473 is fixedly connected to the side of the buffer frame 471 close to the contact frame 461, and a buffer block 474 is fixedly connected to the middle of the side of the buffer plate 473; when the contact frame 461 is reset by the stretching of the fourth spring 45, the contact frame 461 and the buffer frame 471 are connected. Impact, by providing a buffer block 474 in the middle of the buffer plate 473, and the material of the buffer block 474 is rubber, it can prevent the impact force between the contact frame 461 and the buffer plate 473 from being too large when the contact plate 463 is reset by the extension of the fourth spring 45, thereby preventing damage to the contact plate 463 and the contact frame 461. At the same time, when the contact frame 461 and the buffer block 474 buffer the impact, the vibration force generated by the impact can shake off the grease adhering to the contact plate 463; The specific workflow is as follows: During operation, the grease enters the tank body 1 through the feeding component 3, and the motor 7 is turned on, and the stirring component 6 is driven by the output end of the motor 7 to rotate in the tank body 1, thereby stirring the grease in the tank body 1. When the stirring and mixing is completed, the discharging component 4 is opened to discharge and transport the grease; When the material enters the tank body 1, by turning on the motor 7, the output end of the motor 7 drives the stirring blade 62 and the stirring block 63 through the stirring rod 61 to rotate in the tank body 1, and the grease and fat in the tank body are fully mixed and stirred. After the stirring work is completed, the grease in the tank body 1 is discharged through the discharging component 4. Since the separation between the soap stock and the grease cannot be completely thorough, a small amount of neutral oil may adhere to the inner wall of the device after the stirring work is completed. If this part of the neutral oil is not cleaned in time, it may oxidize and deteriorate after a long time. By turning on the motor 7, the stirring rod 61 is driven by the output end of the motor 7 to rotate rapidly in the tank body 1, so that the cleaning mechanism 64 cleans the inner wall of the tank body 1, thereby preventing a small amount of neutral oil from adhering to the inner wall of the tank body 1 for a long time, thereby causing deterioration. After the grease in the tank body 1 is discharged, the motor 7 is turned on and the stirring rod 61 is driven by the output end of the motor 7 to rotate rapidly in the tank body 1. The centrifugal force causes the connecting plate 643 to slide out of the sliding groove 641 through the sliding rod 642, thereby driving the scraper 646 and the rubber plate 645 to move toward the inner wall of the tank body 1 through the connecting plate 643. By bending the rubber plate 645 on the connecting plate 643 at a greater angle than the scraper 646, when the stirring rod 61 rotates rapidly, the connecting plate 643 is driven by the centrifugal force to disengage the connecting plate 643 from the sliding groove 641, and can first pass through the rubber plate 645. 45 collides with the inner wall of the tank body 1, and the rubber material of the rubber plate 645 reduces the impact force between the inner wall of the tank body 1, so that the stirring rod 61 drives the scraper 646 to clean the inner wall of the tank body 1 through the connecting plate 643, and the scraper 646 can scrape off the grease dried on the inner wall of the tank body 1. At the same time, since the bending angle of the rubber plate 645 is greater than that of the scraper 646, the rubber plate 645 can be in contact with the inner wall of the tank body 1, thereby avoiding scratches on the inner wall of the tank body 1 when cleaning the inner wall of the tank body 1 for a long time, thereby reducing the service life of the tank body 1; When deacidifying and stirring industrial grease, since industrial mixed grease comes from a wide range of sources, it may contain various impurities, such as mechanical impurities, solid particles and colloidal impurities. If these impurities are not filtered, they will have many adverse effects on the deacidifying and stirring process. After being fixedly connected to the feed pipe 31 through the external pipe, the grease continues to enter the tank body 1 through the feed pipe 31. By providing a mesh plate 32 on the inner side of the feed pipe 31, the particulate impurities in the grease are filtered. At the same time, when the industrial grease continues to pass through the feed pipe 31, the impact of the grease causes the bracket 34 to move to the side away from the mesh plate 32 through the telescopic rod 33. At the same time, when the mesh plate 32 is filtering the working grease, when impurities in the grease cause the mesh plate 32 to be blocked, the impact force of the grease in the feed pipe 31 is less than the tensile force of the second spring 36, so that the bracket 34 drives the ejection mechanism 35 to move toward the mesh plate 32, thereby ejecting the impurities stuck in the mesh of the mesh plate 32, thereby ensuring the normal filtering of the mesh plate 32. When the impact force of the grease in the feed pipe 31 is less than the tensile force of the second spring 36, the bracket 34 drives the ejection rod 351 to move toward the mesh plate 32, so that the ejection rod 351 drives the ejection pin 357 to eject the impurities stuck in the mesh of the mesh plate 32. At the same time, when the extrusion force between the ejection pin 357 and the impurities stuck in the mesh of the mesh plate 32 is greater than the tensile force of the third spring 358, the ejection pin 357 moves in the slot 352 through the moving rod 354 and the moving block 353. At the same time, the buffering force of the third spring 358 is used to prevent the ejection pin 357 from clearing the blockage. The extrusion force of impurities stuck in the mesh of the mesh plate 32 is too great, which may cause extrusion damage to the ejector pin 357. At the same time, when the grease feeding work is completed, the third spring 358 is reset and stretched to drive the bracket 34 to move toward the mesh plate 32. The ejector rod 351 continues to pass through the mesh of the mesh plate 32, so that the ejector rod 351 drives the extrusion plate 356 to clean and scrape the inner side of the mesh of the mesh plate 32, thereby preventing grease residue from drying on the inner wall of the mesh. If the cleaning work is not performed for a long time, the dry residue will accumulate on the inner wall of the mesh, causing the grease feeding speed to slow down. After the grease in the tank body 1 is mixed, the gate valve mechanism 42 is operated to discharge the grease in the discharge pipe 41. At the same time, the grease flows out through the discharge pipe 41. The impact force of the grease causes the contact mechanism 46 to pull the fourth spring 45 to move on the guide rod 44. At the same time, after the grease is discharged, when the impact force of the grease passing through the discharge pipe 41 is less than the tensile force of the fourth spring 45, the contact mechanism 46 is pulled by the reset of the fourth spring 45 to move on the guide rod 44. At the same time, the inner wall of the discharge pipe 41 is cleaned by the contact mechanism 46. At the same time, when the contact mechanism 46 is reset by the stretching of the fourth spring 45, the contact mechanism 46 and the buffer mechanism 47 are used to buffer the collision, thereby avoiding damage to the contact mechanism 46. After the grease is discharged, when the impact force of the grease passing through the discharge pipe 41 is less than the tensile force of the fourth spring 45, the contact frame 461 is pulled by the fourth spring 45 to move on the guide rod 44, so that the contact frame 461 drives the contact plate 463 to clean the inner wall of the discharge pipe 41, thereby preventing a large amount of grease from flowing out through the discharge pipe 41 and remaining on the inner wall of the discharge pipe 41, thereby preventing the grease from drying on the inner wall of the discharge pipe 41. When the contact frame 461 is reset by the stretching of the fourth spring 45, the contact frame 461 collides with the buffer frame 471. A buffer block 474 is provided in the middle of the buffer plate 473, and the material of the buffer block 474 is rubber. This avoids excessive impact force between the contact frame 461 and the buffer plate 473 when the contact plate 463 is reset by the stretching of the fourth spring 45, thereby causing damage to the contact plate 463 and the contact frame 461. At the same time, when the contact frame 461 and the buffer block 474 perform a buffering collision, the grease adhering to the contact plate 463 can be shaken off by the vibration force generated during the collision.
