Description

Technical Field

[0001] The invention relates to the technical field of grease filtering, and in particular to a complete set of fully automatic constant-pressure numerically controlled grease filtering and polishing devices. Background Art

[0002] Grease filtering and polishing device is a kind of equipment used for processing grease products. It is mainly used to remove solid impurities, colloidal particles, water and other foreign matter in grease, and to convert turbid grease into pure and clear products, thereby improving its quality and added value.

[0003] There are three main types of existing grease filtration technologies: mesh filtration, centrifugal filtration and microporous filtration. Mesh filtration is mostly used to filter larger particles, and contains more impurities after filtration. Centrifugal filtration uses centrifugal force to separate impurities and particles in grease. The disadvantage is that oil and wax are difficult to separate and the operation is inconvenient. Microporous filters can filter out tiny impurities and particles and are usually used for high-precision filtration. The disadvantage is that the filtration speed is slow and the cost is high.

[0004] In order to improve the accuracy of grease filtration, it is necessary to keep the grease at a certain temperature and pressure during filtration. A certain pressure and temperature can enhance the interaction between grease molecules, which helps to reduce the effect of the size of particles in the grease on filtration. At the same time, maintaining appropriate pressure and temperature helps to improve compatibility, allowing the filter medium to better capture and separate solid particles in the grease, making the filtration more accurate and reliable.

[0005] In the process of filtering grease, if the pressure and temperature are not properly controlled, the filter medium may be deformed or damaged, making it difficult to completely isolate solid particles. These particles may flow with the filtrate to the next stage or enter the discharge pipe, affecting subsequent treatment. In addition, too low a temperature may cause the filter medium to become fragile and easy to rupture, while too high a pressure may cause the filter medium to deform or damage, which greatly affects the filtration efficiency and reduces the quality of the filtered grease.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions 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 creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 9 As shown, this embodiment proposes a fully automatic constant pressure CNC grease filtering and polishing device, including a filter press body 1, a fixed frame 2, a crude oil tank 3, a heating component, a cooling component, a material mixing component, a pressure tank 4, a control component, a feeding component, a finished oil tank 5 and a digital controller 6. The fixed frame 2 is arranged on the side of the filter press body 1, the crude oil tank 3 is fixedly installed on the fixed frame 2, and the heating component is installed inside the crude oil tank 3 for heating the grease. The heating component includes a spiral heating coil 7 and a heater 8. The spiral heating coil 7 is fixedly installed inside the crude oil tank 3, and the heater 8 is fixedly installed on the fixed frame 2. The output end of the heater 8 is connected to the two ends of the spiral heating coil 7.

[0025] Specifically, when filtering and polishing the grease, the crude oil is first passed into the feed pipe 45, which is connected to the top of the crude oil tank 3, and the crude oil enters the crude oil tank 3 through the feed pipe 45. At this time, the feed pipe 45 is closed, and the temperature at which the grease needs to be heated is determined according to the type of grease. When the grease temperature is higher than the required temperature, the grease temperature is lowered by the cooling component. When the grease temperature is lower than the required temperature, the grease needs to be heated. At this time, the digital controller 6 is set, and a signal transmitter is set on the digital controller 6, and a matching signal receiver is set on the heater 8. At this time, the digital controller The device 6 sends a signal to the heater 8, and then the heater starts, and the grease in the crude oil tank 3 is heated by the spiral heating coil 7. Through the cooperation with the material leveling component, when the grease is heated to a certain degree, the grease is discharged into the pressure tank 4. At this time, the control component is started to adjust the pressure in the pressure tank 4 according to the type of grease, and then the grease is sent into the filter press body 1 through the feeding component for filtration. By adjusting the grease pressure and temperature, the speed, output and glossiness of the grease filtration are guaranteed to achieve the best effect, and at the same time, the use cost of the filter paper and filter cloth is effectively controlled.

[0026] Among them, different oils require different temperatures and pressures during the filtration process. For example, when the temperature of sunflower oil is controlled at 20°-25° and the pressure is controlled at 1.5PA-2PA, the yield, glossiness and speed of sunflower oil will reach the best results. When the temperature of rapeseed oil is controlled at 30°-35° and the pressure is controlled at 2PA-2.5PA, the yield, glossiness and speed of rapeseed oil will reach the best results. When the temperature of linseed oil is controlled at 15°-20° and the pressure is controlled at 1PA-1.5PA, the yield, glossiness and speed of linseed oil will reach the best results.

[0027] like Figure 3 , Figure 4 As shown, the cooling component is installed inside the crude oil tank 3, and the cooling component is located inside the heating component, which is used to cool the oil. The cooling component includes a water tank 9, a spiral cooling pipe 10, a drain pipe 11, a first valve 12 and a circulation unit. The water tank 9 is fixedly installed on the fixed frame 2, the spiral cooling pipe 10 is arranged inside the crude oil tank 3, and the spiral cooling pipe 10 is located inside the spiral heating coil 7. The drain pipe 11 is connected between the lower end of the spiral cooling pipe 10 and the upper side of the water tank 9. The first valve 12 is fixedly installed at the end of the drain pipe 11. The circulation unit is installed on the water tank 9 and is used to inject coolant into the spiral cooling pipe 10.

[0028] Specifically, when the oil temperature in the crude oil tank 3 is higher than the required temperature, the coolant in the water tank 9 is extracted through the setting of the circulation unit and sent to the inside of the spiral cooling pipe 10. At this time, the first valve 12 is in an open state, and the coolant entering the spiral cooling pipe 10 will return to the inside of the water tank 9 through the drain pipe 11, thereby cooling the crude oil through the coolant until the temperature of the crude oil drops to the set temperature, at which time the first valve 12 can be closed.

[0029] The above, such as Figure 4 As shown, the circulation part includes a water pump 13, a water injection pipe 14 and a water chiller 15. The water pump 13 is fixedly installed on the water tank 9. The water injection pipe 14 is connected between the output end of the water pump 13 and the upper end of the spiral cooling tube 10. The water chiller 15 is fixedly installed on the water tank 9. The input end of the water chiller 15 is connected to the water tank 9, and the output end of the water chiller 15 is connected to the input end of the water pump 13.

[0030] Specifically, when adding coolant to the spiral cooling tube 10, start the water pump 13, the water pump 13 extracts the coolant in the water tank 9 through the cooler, and at the same time starts the cooler to cool the extracted coolant so that the coolant entering the water pump 13 maintains the same temperature, and then the coolant is sent into the spiral cooling tube 10 through the water injection pipe 14.

[0031] like Figures 5 to 7 As shown, the material leveling assembly is installed inside the crude oil tank 3 and is used to stir the grease in the crude oil tank 3. The material leveling assembly includes a motor 16, a drive shaft 17, a mounting shell 18, a transmission cylinder 19, a transmission part and a material leveling part. The motor 16 is fixedly installed on the top of the crude oil tank 3, the drive shaft 17 is fixedly installed on the output end of the motor 16, the mounting shell 18 is fixedly installed on the bottom of the crude oil tank 3, the inner bottom wall of the mounting shell 18 is rotatably connected to the bottom end of the drive shaft 17, and a transmission cylinder 19 is rotatably installed at the bottom of the crude oil tank 3. The upper end of the transmission cylinder 19 is located inside the crude oil tank 3, and the transmission cylinder 19 is rotatably matched with the drive shaft 17. The transmission part is installed on the mounting shell 18, and the transmission part is used to drive the transmission cylinder 19 to rotate. The material leveling part is installed on the transmission cylinder 19 and the drive shaft 17 to evenly distribute the grease in the crude oil tank 3.

[0032] Specifically, when adjusting the temperature of the grease, in order to make the temperature of the grease more uniform, the grease needs to be slowly stirred to make the temperature of each area more uniform. At this time, the motor 16 is started, and the motor 16 drives the drive shaft 17 to rotate. The drive shaft 17 drives the transmission cylinder 19 to rotate synchronously through the setting of the transmission part. At this time, the transmission cylinder 19 and the drive shaft 17 are opposite in direction, and the material mixing part is driven to rotate, so as to stir the grease in the crude oil tank 3 and make the temperature of each part more uniform.

[0033] The above, such as Figure 6As shown, the transmission part includes a first gear 20, a second gear 21, an intermediate gear 22, a transmission bevel gear 23 and a reversing bevel gear 24. The first gear 20 is fixedly mounted on the bottom end of the drive shaft 17, the second gear 21 is fixedly mounted on the bottom end of the transmission cylinder 19, the second gear 21 is located inside the mounting shell 18, and intermediate gears 22 are rotatably mounted at the upper and lower ends inside the mounting shell 18. The two intermediate gears 22 are respectively meshed with the first gear 20 and the second gear 21. Transmission bevel gears 23 are fixedly mounted on the two intermediate gears 22, and the two transmission bevel gears 23 are arranged opposite to each other. The reversing bevel gear 24 is rotatably mounted on the inner side wall of the mounting shell 18, and the reversing bevel gear 24 is respectively meshed with the two transmission bevel gears 23.

[0034] Specifically, as the driving shaft 17 rotates, the driving shaft 17 drives the first gear 20 to rotate. The first gear 20 drives one of the transmission bevel gears 23 to rotate through the setting of the intermediate gear 22. Through the setting of the reversing bevel gear 24, the other transmission bevel gear 23 can be driven to rotate through the reversing bevel gear 24, thereby driving the second gear 21 to rotate through the other intermediate gear 22. Due to the setting of the reversing bevel gear 24, the second bevel gear and the first bevel gear have opposite directions. At this time, the transmission cylinder 19 can be driven to rotate through the second bevel gear.

[0035] The above, such as Figure 7 As shown, the material mixing section includes a stirring blade 25, a fixed ring 26 and a spoiler rod 27. The stirring blades 25 are fixedly installed on the driving shaft 17 and the transmission cylinder 19. The two stirring blades 25 are symmetrically arranged relative to the center position of the spiral cooling tube 10. The driving shaft 17 and the transmission cylinder 19 are fixedly installed with a fixed ring 26. The two fixed rings 26 are located between the two stirring blades 25. The two fixed rings 26 are both circularly fixed with multiple spoiler rods 27 at equal angles, and the spoiler rods 27 are arranged obliquely.

[0036] Specifically, as the transmission cylinder 19 and the drive shaft 17 rotate in opposite directions, the two drive the corresponding stirring blades 25 and the fixed ring 26 to rotate respectively. The two stirring blades 25 are arranged relatively to each other, so that convection is formed in the process of stirring the crude oil, thereby increasing the stirring speed. At the same time, through the setting of the spoiler rod 27, as the fixed ring 26 rotates, the spoiler rod 27 rotates around the axial position of the fixed ring 26, thereby stirring the crude oil, and can make the crude oil flowing between the two stirring blades 25 more dispersed, thereby improving the uniformity of the crude oil temperature.

[0037] like Figure 8As shown, the pressure tank 4 is arranged on one side of the crude oil tank 3, and the control component is installed inside the pressure tank 4 to control the pressure inside the pressure tank 4. The control component includes a temperature sensor 28, a pressure inlet valve 29, a pressure relief valve 30, a first pressure gauge 31 and a liquid level gauge 32. The temperature sensor 28 is fixedly installed inside the crude oil tank 3 and the pressure tank 4. The pressure inlet valve 29 is connected to the top of the pressure tank 4, the pressure relief valve 30 is connected to the top of the pressure tank 4, the pressure relief valve 30 is located on one side of the pressure inlet valve 29, the first pressure gauge 31 is fixedly installed on the pressure tank 4, and the liquid level gauge 32 is fixedly installed on the pressure tank 4.

[0038] Specifically, after the temperature of the grease in the crude oil tank 3 is adjusted, the grease is discharged into the pressure tank 4. The amount of grease in the pressure tank 4 is observed by setting the liquid level meter 32. When a certain amount is reached, the discharge of the oil into the pressure tank 4 can be stopped. Then the pressure inlet valve 29 is connected to the pressurizing device, and the pressure tank 4 is pressurized by the pressurizing device. At this time, the pressure relief valve 30 is adjusted according to the type of grease, so that the pressure in the pressure tank 4 can be ensured to reach the set value by setting the pressure relief valve 30 and observing the first pressure gauge 31 at the same time.

[0039] Among them, through the setting of two temperature sensors 28, the oil temperature in the crude oil tank 3 and the pressure tank 4 is detected respectively. Both temperature sensors 28 are provided with signal transmitters, and the digital controller 6 is provided with matching signal receivers. When adjusting the oil temperature in the crude oil tank 3, according to the temperature of the external environment, if the external environment temperature is lower than the required temperature, the oil is adjusted to a higher temperature in the required temperature range; if the external environment temperature is higher than the required temperature, the oil is adjusted to a lower temperature close to the required temperature range, so that when the oil enters the pressure tank 4, the oil temperature fluctuates, making the oil temperature closer to the maximum value or minimum value of the required temperature range, thereby improving the control over the temperature.

[0040] The above, such as Figure 3 As shown, it also includes an oil pump 33, an oil inlet pipe 34, a second valve 35, an oil pipe 36 and a one-way valve 37. The oil pump 33 is fixedly installed on the fixed frame 2, the oil inlet pipe 34 is connected between the input end of the oil pump 33 and the bottom end of the crude oil tank 3, the second valve 35 is fixedly installed on the oil inlet pipe 34, the oil pipe 36 is connected to the output end of the oil pump 33, and the one-way valve 37 is connected between the other end of the oil pipe 36 and the pressure tank 4.

[0041] Specifically, after the temperature of the grease in the crude oil tank 3 is adjusted, it needs to be discharged into the pressure tank 4. At this time, the oil pump 33 is started, and the second valve 35 is opened. The oil pump 33 extracts the grease in the crude oil tank 3 through the oil inlet pipe 34, and then sends the grease into the pressure tank 4 through the oil pipe 36. Through the setting of the one-way valve 37, when the pressure tank 4 is pressurized, the oil pump 33 will not be affected, thereby reducing the probability of damage to the oil pump 33.

[0042] like Fig. 9 As shown, the feeding assembly is installed on the filter press body 1, and is used to feed the grease in the control assembly into the inside of the filter press body 1. The finished oil tank 5 is arranged on the side of the filter press body 1, and the digital controller 6 is fixedly installed on the fixed frame 2. The feeding assembly includes a gear pump 38, a suction pipe 39, a third valve 40, a discharge pipe 41, a second pressure gauge 42, a discharge pipe 43 and a fourth valve 44. The gear pump 38 is fixedly installed at the lower part of the filter press body 1, the suction pipe 39 is connected between the input end of the gear pump 38 and the pressure tank 4, the third valve 40 is fixedly installed on the suction pipe 39, the discharge pipe 41 is connected between the output end of the gear pump 38 and the input end of the filter press body 1, the second pressure gauge 42 is fixedly installed on the discharge pipe 41, the discharge pipe 43 is connected between the discharge end of the filter press body 1 and the finished oil tank 5, and the fourth valve 44 is fixedly installed on the discharge pipe 43.

[0043] Specifically, when the pressure in the pressure tank 4 is adjusted, the third valve 40 is opened, the gear pump 38 is started to extract the grease in the pressure tank 4 through the suction pipe 39, and then the grease is sent to the discharge pipe 41, and then the grease is sent to the filter press body 1 through the discharge pipe 41, so as to filter the grease, and then the filtered grease is discharged into the discharge pipe 43. At this time, the fourth valve 44 is opened to send the filtered grease into the finished oil tank 5 for storage.

[0044] In summary, when filtering and polishing the grease, the crude oil is first passed into the feed pipe 45, which is connected to the top of the crude oil tank 3, and the crude oil enters the crude oil tank 3 through the feed pipe 45. At this time, the feed pipe 45 is closed, and the required temperature of the grease is determined according to the type of grease. If the external ambient temperature is lower than the required temperature, the grease is adjusted to a temperature range close to the higher temperature of the required temperature range. If the external ambient temperature is higher than the required temperature, the grease is adjusted to a temperature range close to the lower temperature of the required temperature range.

[0045] When the grease temperature is higher than the required temperature, it is necessary to lower the grease temperature and start the water pump 13. The water pump 13 extracts the coolant in the water tank 9 through the cooler, and starts the cooler to cool the extracted coolant so that the coolant entering the water pump 13 is kept at the same temperature. Then, the coolant is sent into the spiral cooling pipe 10 through the water injection pipe 14. At this time, the first valve 12 is in the open state, and the coolant entering the spiral cooling pipe 10 will return to the water tank 9 through the drain pipe 11, thereby cooling the crude oil through the coolant until the temperature of the crude oil drops to the set temperature, at which time the first valve 12 can be closed.

[0046] When the grease temperature is lower than the required temperature, the grease needs to be heated. At this time, through the setting of the digital controller 6, a signal transmitter is provided on the digital controller 6, and a matching signal receiver is provided on the heater 8. At this time, the digital controller 6 sends a signal to the heater 8, and then the heater is started to heat the grease in the crude oil tank 3 through the spiral heating coil 7.

[0047] When adjusting the temperature of the grease, in order to make the temperature of the grease more uniform, the grease needs to be slowly stirred to make the temperature of each area more uniform. At this time, the motor 16 is started, and the motor 16 drives the drive shaft 17 to rotate. As the drive shaft 17 rotates, the drive shaft 17 drives the first gear 20 to rotate. The first gear 20 drives one of the transmission bevel gears 23 to rotate through the setting of the intermediate gear 22. Through the setting of the reversing bevel gear 24, the other transmission bevel gear 23 can be driven to rotate through the reversing bevel gear 24, thereby driving the second gear 21 to rotate through the other intermediate gear 22. Due to the setting of the reversing bevel gear 24, the second gear 21 can be driven to rotate. , the second bevel gear and the first bevel gear rotate in opposite directions, and the transmission cylinder 19 can be driven to rotate by the second bevel gear. As the transmission cylinder 19 and the drive shaft 17 rotate in opposite directions, the two respectively drive the corresponding stirring blades 25 and the fixed ring 26 to rotate. The two stirring blades 25 are arranged relatively to each other, so that convection is formed in the process of stirring the crude oil, thereby increasing the stirring speed. At the same time, through the setting of the spoiler rod 27, as the fixed ring 26 rotates, the spoiler rod 27 rotates around the axial position of the fixed ring 26, thereby stirring the crude oil, and can make the crude oil flowing between the two stirring blades 25 more dispersed, thereby improving the uniformity of the crude oil temperature.

[0048] After the temperature of the grease in the crude oil tank 3 is adjusted, the grease needs to be discharged into the pressure tank 4. At this time, the oil pump 33 is started, and the second valve 35 is opened. The oil pump 33 extracts the grease in the crude oil tank 3 through the oil inlet pipe 34, and then sends the grease into the pressure tank 4 through the oil pipe 36. Through the setting of the one-way valve 37, when the pressure tank 4 is pressurized, the oil pump 33 will not be affected, thereby reducing the probability of damage to the oil pump 33. Through the setting of the liquid level meter 32, the amount of grease in the pressure tank 4 is observed. When a certain amount is reached, the discharge of oil into the pressure tank 4 can be stopped, and then the pressure inlet valve 29 is connected to the pressurizing device, and the pressure tank 4 is pressurized by the pressurizing device. At this time, the pressure relief valve 30 is adjusted according to the type of grease, so that through the setting of the pressure relief valve 30, the first pressure gauge 31 is observed at the same time to ensure that the pressure in the pressure tank 4 reaches the set value.

[0049] When the pressure in the pressure tank 4 is adjusted, the third valve 40 is opened, and the gear pump 38 is started to extract the grease in the pressure tank 4 through the suction pipe 39, and then the grease is sent to the discharge pipe 41, and then the grease is sent to the filter press body 1 through the discharge pipe 41, so as to filter the grease. By adjusting the grease pressure and temperature, the speed, output and glossiness of the grease filtration are guaranteed to achieve the best effect, and the use cost of the filter paper and the filter cloth is also effectively controlled. Then the filtered grease is discharged into the discharge pipe 43. At this time, the fourth valve 44 is opened to send the filtered grease into the finished oil tank 5 for storage.
