Description

Technical Field

[0001] The invention relates to the technical field of composite oil processing, in particular to an oil phase filtering device and a method thereof. Background Art

[0002] Emulsion is a kind of water-in-oil latex-like substance, which is widely used in mining, construction and military fields. Its performance is closely related to the composition and dosage of compound oil. Compound oil provides the chemical energy required in the explosion process of emulsion explosives, ensuring that a large amount of energy can be released instantly, thereby producing a powerful explosion effect. Secondly, compound oil can effectively reduce the viscosity and improve its fluidity, which is convenient for filling and use during production and transportation. In addition, the ingredients in compound oil help to form a stable emulsification system, enhance the emulsification effect, and improve the application ability in humid environments. The composition of compound oil usually includes mineral oil, vegetable oil, synthetic oil, surfactants and various additives, among which mineral oil occupies a large proportion as the base oil, vegetable oil increases environmental protection and lubricity, and synthetic oil improves low-temperature fluidity and high-temperature stability. Surfactants are the key ingredients to ensure the stability of oil-water emulsions, while additives such as antioxidants and anti-corrosion agents further improve the storage stability and service life of the emulsions. Due to the differences in raw materials, compound oils and their additives often contain fine metal particles, dust and other pollutants. The presence of these impurities may have a negative impact on the physical and chemical properties of explosives and even cause safety hazards. Therefore, the filter device can effectively block these mechanical impurities, thereby ensuring the safety of the production process;

[0003] For example, an emulsion explosive composite oil phase filter disclosed in the authorization announcement number CN207591398U includes a mounting tube, a first filter tube and a second filter tube, legs are symmetrically installed at the left and right ends of the bottom of the mounting tube, a liquid outlet is vertically connected to the middle of the bottom end of the mounting tube, and a liquid outlet pipe is fixedly connected to the bottom of the liquid outlet, a flow rate sensor is installed at the right end of the liquid outlet pipe, and a processor is installed at the right end of the bottom of the mounting tube. The present invention has a flow rate sensor installed at the right end of the liquid outlet pipe, a processor installed at the right end of the bottom of the installation tube, the processor is located on the right side of the liquid outlet pipe, and a voice prompter is vertically installed on the right side of the installation tube. When the flow rate sensor senses that the flow rate of the composite oil in the liquid outlet pipe is less than the set value, the flow rate sensor transmits data to the processor, and the processor transmits a signal to the voice prompter to remind the operator to pay attention to the clogging of the filter screen. However, during the operation, the staff still needs to disassemble the filter and clean the filter screen, filter cartridge and other accessories one by one. There is no component inside the machine body that can quickly clean the filter screen and filter cartridge. The staff must be familiar with the equipment structure and disassemble it according to the correct steps. At this time, the downtime of the filtering device is too long. In a large-scale production environment, it will cause the production line to stop frequently, and the cleaning process is completely dependent on manual labor. Some impurities will also remain due to incomplete cleaning, thereby reducing the overall filtrate performance of the filter and the production quality of the emulsion explosive.

[0017] The present invention also provides an oil phase filtration method, such as the oil phase filtration device described above, comprising the following steps:

[0018] S101: Open the manhole on the surface of the external oil filter tank, install one or more filter membranes on the inner wall of the filter cartridge of the rotating centrifugal module, and send the processed composite oil for emulsion explosives to be filtered into the filter cartridge of the rotating centrifugal module through the pumping unit, oil pipe, manhole and other components of the external oil tank;

[0019] S102: The staff turns on the rotating centrifugal module through the PLC control panel. The rotating centrifugal module uses the principle of centrifugal force to separate the solid impurities and oil in the composite oil through high-speed rotation. The clean oil passes through the filter membrane and flows into the internal chamber of the external filter oil tank. Finally, it converges at the conical tank bottom area of ​​the external filter oil tank through the arc-shaped through-cavity of the suspended oil guide platform.

The Z-axis lifting unit drives the support platform, the hollow column, and the four-way scrubbing module with adjustable tension to move downward until the four-way scrubbing module with adjustable tension is lifted or lowered to a preset position;

[0021] S104: After the tension-adjustable four-way scrubbing module reaches the cleaning position, the module contacts the inner wall of the filter cartridge of the rotating centrifugal module and applies appropriate pressure to ensure the cleaning effect. At this time, the gear drive unit starts to drive the scrubbing module to rotate around the hollow column. The design of the tension-adjustable four-way scrubbing module enables it to evenly apply pressure to the filter cartridge of the rotating centrifugal module during rotation, thereby effectively removing impurities and dirt attached to the inner wall of the filter cartridge.

[0022] Compared with the prior art, the beneficial effects of the present invention are: the oil phase filtering device and method thereof utilize a Z-axis lifting unit to adjust the height of the four-way scrubbing module with adjustable tension, so that it can accurately contact the inner wall of the filter cartridge of the rotating centrifugal module. During the entire cleaning process, the support platform and the hollow column provide necessary support to ensure that the cleaning module remains stable during cleaning and avoid any possible misoperation. When the filtration work is completed, the oil active pumping unit stops operating, and the system enters the cleaning stage. The axis lifting unit lifts the four-way scrubbing module with adjustable tension to a preset position to contact the inner wall of the filter cartridge. At this time, the tension adjustment mechanism of the tension-adjustable four-way scrubbing module is automatically adjusted according to the degree of dirt on the inner wall of the filter cartridge to ensure that appropriate pressure is applied during the cleaning process. The device can complete the cleaning without disassembling any parts, thereby significantly reducing the downtime of the device. After the device completes the filtration, the filter cartridge is quickly cleaned to maximize the use efficiency of the device. By precisely controlling the pressure and rotation speed of the cleaning module, it can be adjusted according to the actual dirt situation of the filter cartridge to ensure cleaning without dead ends. It not only improves the cleaning efficiency and reduces the frequency and cost of later maintenance of the device, but also ensures the cleanliness of the filter cartridge after use, thereby improving the overall production quality of emulsion explosive composite oil.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. 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.

[0037] Embodiment 1, by Figures 1 to 5 The present invention comprises an external oil filter tank 1, a frame 2 is fixed on the outer wall of one side of the external oil filter tank 1, and an oil active pumping unit 5 is installed inside the frame 2, the tapered mouth at the bottom end of the external oil filter tank 1 is connected to the liquid inlet end of the oil active pumping unit 5, a suspended oil guide platform 3 is fixed at one end inside the external oil filter tank 1, and arc-shaped through cavities 301 are arranged on both sides inside the suspended oil guide platform 3, and a rotating centrifugal module 4 for filtering composite oil is arranged at the center position of the top end of the suspended oil guide platform 3;

[0038] A double-layer hollow sealing cover 6 is fixed at the top opening position of the outer oil filter tank 1. A liquid inlet pipe 601 is arranged on one side of the inner part of the double-layer hollow sealing cover 6. A C-mouth frame 7 is fixed on the back of the double-layer hollow sealing cover 6. A Z-axis lifting unit 9 is arranged on the top of the C-mouth frame 7. A support 8 is installed on the movable end of the Z-axis lifting unit 9. A hollow column 10 is installed at the center position of the bottom end of the support 8. The bottom end of the hollow column 10 extends to the inner part of the outer oil filter tank 1. The central axis of the hollow column 10 coincides with the central axis of the outer oil filter tank 1. The outer peripheral surface of the hollow column 10 is provided with a tension-adjustable four-way scrubbing module 11. The tension-adjustable four-way scrubbing module 11 is used to contact the rotating centrifugal module 4.

[0039] The gear driving unit 12 is arranged inside the double-layer hollow sealing cover 6 and is used to drive the adjustable four-way scrubbing module 11 to rotate around the hollow column 10. A PLC control panel 13 is installed on the outer wall of one side of the frame 2. The output end of the PLC control panel 13 is electrically connected to the rotating centrifugal module 4, the oil active pumping unit 5, the Z-axis lifting unit 9, the adjustable four-way scrubbing module 11, and the input end of the gear driving unit 12;

[0040] A double-elbow waste pipe 505 is installed on one side of the bottom end of the outer filter oil tank 1 , and a second switch valve 506 is installed on one end of the double-elbow waste pipe 505 away from the outer filter oil tank 1 .

[0041] An oil phase filtration method of this embodiment, such as the above-mentioned oil phase filtration device, comprises the following steps:

[0042] S101: Open the manhole on the surface of the external oil filter tank 1, install one or more filter membranes on the inner wall of the filter cartridge of the rotating centrifugal module 4, and send the processed composite oil for emulsion explosives to be filtered into the filter cartridge of the rotating centrifugal module 4 through the pumping unit, oil pipe, manhole and other components of the external oil tank;

[0043] S102: The staff starts the rotating centrifugal module 4 through the PLC control panel 13. The rotating centrifugal module 4 uses the principle of centrifugal force to separate the solid impurities and oil in the composite oil through high-speed rotation. The clean oil passes through the filter membrane and flows into the inner chamber of the outer filter oil tank 1, and finally converges at the conical tank bottom area of ​​the outer filter oil tank 1 through the arc-shaped through cavity 301 of the suspended oil guide platform 3. The oil active pumping unit 5 introduces the filtered oil from the inner part of the outer filter oil tank 1 into the oil storage tank to ensure that the composite oil successfully completes the filtering process;

[0044] S103: Once the composite oil filtration is completed, the staff turns off the oil active pumping unit 5 through the PLC control panel 13, and turns on the Z-axis lifting unit 9 through the PLC control panel 13 to move, and the Z-axis lifting unit 9 drives the support platform 8, the hollow column 10, and the adjustable four-way scrubbing module 11 to move downward until the adjustable four-way scrubbing module 11 is lifted or lowered to a preset position;

[0045] S104: After the tension-adjustable four-way scrubbing module 11 reaches the cleaning position, the module contacts the inner wall of the filter cartridge of the rotating centrifugal module 4 and applies appropriate pressure to ensure the cleaning effect. At this time, the gear drive unit 12 starts to drive the scrubbing module to rotate around the hollow column 10. The design of the tension-adjustable four-way scrubbing module 11 enables it to evenly apply pressure to the filter cartridge of the rotating centrifugal module 4 during rotation, thereby effectively removing impurities and dirt attached to the inner wall of the filter cartridge.

[0046] Embodiment 2, based on embodiment 1, Figure 6 and Figure 7 It is given that the rotary centrifugal module 4 includes a turntable 402 rotatably mounted at the center position of the top of the suspended oil guide platform 3 and an inner cylinder 403 fixed at the center position of the top of the turntable 402, and the outer wall of the inner cylinder 403 is provided with honeycomb mesh holes, and the rotary centrifugal module 4 also includes a concave cavity extending downwardly arranged at the center position of the bottom end of the suspended oil guide platform 3 and a worm gear reduction motor 401 installed inside the concave cavity, and the output end of the worm gear reduction motor 401 is fixedly connected to the bottom end of the turntable 402, and the external composite oil to be filtered is injected into the interior of the inner cylinder 403 through the manhole, and at this time, the filter membrane on the inner wall of the inner cylinder 403 will isolate the composite oil from the internal chamber of the external filter oil tank 1;

[0047] The staff can start the worm gear reduction motor 401 through the PLC control panel 13 to work, and the worm gear reduction motor 401 will drive the turntable 402 and the inner cylinder 403 to rotate together, which can effectively separate the solid impurities in the oil through the action of centrifugal force, greatly improving the filtering efficiency;

[0048] A bottom ring 404 is fixed at the edge of the top of the suspended oil guide platform 3, and a steel wheel 405 is rotatably installed at the edge of the top of the bottom ring 404. The steel wheel 405 contacts the outer wall of the turntable 402. During the rotation of the turntable 402 and the inner cylinder 403, a plurality of steel wheels 405 are used to improve the rotation stability of the turntable 402 and the inner cylinder 403, so that the inner cylinder 403 remains stable during high-speed rotation.

[0049] The self-locking function of the worm gear reduction motor 401 also allows the turntable 402 and the inner cylinder 403 to remain stable after stopping, thereby preventing the rotation of the adjustable four-way scrubbing module 11 from causing the inner cylinder 403 to rotate together;

[0050] The oil active pumping unit 5 comprises a right-angle oil outlet pipe 501 installed at the bottom end of the outer oil filter tank 1, a first switch valve 502 installed at one end of the right-angle oil outlet pipe 501 away from the outer oil filter tank 1, and a delivery pump 504 fixed on the inner wall of the frame 2 above the first switch valve 502. An oil-water separator 503 is installed at the liquid inlet end of the delivery pump 504 through a steel pipe. The liquid inlet of the oil-water separator 503 at one end away from the delivery pump 504 is connected to one end of the first switch valve 502 through a steel pipe. In the process of discharging the liquid, the oil-water separator 503 can reduce the water content in the oil. The vertical center axis of the right-angle oil outlet pipe 501 is collinear with the vertical center axes of the turntable 402 and the bottom ring 404.

[0051] The filtered composite oil will flow along the inner wall of the outer filter tank 1 and enter the tank bottom area of ​​the outer filter tank 1 through the arc-shaped through cavity 301. At this time, the composite oil enters the right-angle oil outlet pipe 501 and the first switch valve 502. When the delivery pump 504 is working, it can quickly absorb the filtered oil. By controlling the rotation speed and oil outlet pressure of the delivery pump 504, it is ensured that the flow speed of the oil in the pipeline is appropriate to prevent the oil from being oxidized or deteriorated due to too slow a flow rate.

[0052] Embodiment 3, based on embodiment 2, Figure 8 and Fig. 9 It is given that the tension-adjustable four-way scrubbing module 11 includes a cross sleeve 1101 mounted on one end of the surface of the hollow column 10, a support plate 1102 mounted on the surface of the hollow column 10 above the cross sleeve 1101, and an external spline sleeve 1103 fixed at the center position of the top of the support plate 1102. A connecting rod type distance-adjustable cleaning structure 1104 for contacting the inner wall surface of the inner cylinder 403 is installed between the cross sleeve 1101 and the support plate 1102. The gear drive unit 12 drives the external spline sleeve 1103 to rotate, and the external spline sleeve 1103 drives the support plate 1102, the cross sleeve 1101, and the connecting rod type distance-adjustable cleaning structure 1104 to rotate around the hollow column 10. The connecting rod type distance-adjustable cleaning structure 1104 can move on a set trajectory to ensure that the cleaning covers every corner of the inner cylinder 403.

[0053] The adjustable tension four-way scrubbing module 11 also includes a secondary hydraulic cylinder 1105 installed on one side of the top of the support platform 8 and a straight sliding handle 1106 slidably installed at one end of the hollow column 10. The top of the straight sliding handle 1106 is fixedly connected to the bottom end of the piston rod of the secondary hydraulic cylinder 1105. The bottom end of the straight sliding handle 1106 is integrally formed with a lower connecting sleeve 1107. The lower connecting sleeve 1107 is rotatably connected to the top of the external spline sleeve 1103. During the rotation of the external spline sleeve 1103, the lower connecting sleeve 1107 keeps the external spline sleeve 1103 and the straight sliding handle 1106 in a rotating state, and enables the secondary hydraulic cylinder 1105 to normally drive the straight sliding handle 1106, the lower connecting sleeve 1107, the external spline sleeve 1103 and other components to move up and down to adjust the opening degree of the connecting rod type adjustable distance cleaning structure 1104.

[0054] The auxiliary hydraulic cylinder 1105 is controlled by the PLC control panel 13 to move, and the auxiliary hydraulic cylinder 1105 drives the straight sliding handle 1106, the lower connecting sleeve 1107, the outer spline sleeve 1103 and the support plate 1102 to slide down in the vertical extension direction of the hollow column 10, and the sliding movement of the support plate 1102 is converted into the outward expansion movement of the connecting rod type adjustable distance cleaning structure 1104, so that the connecting rod type adjustable distance cleaning structure 1104 gradually approaches the inside of the inner cylinder 403 and contacts it, and the debugging of the adjustable tension four-way scrubbing module 11 is completed. A higher tension is suitable for a dirty surface, while a lower tension is suitable for fine cleaning, reducing the damage to the inner cylinder 403;

[0055] The connecting rod type adjustable distance cleaning structure 1104 comprises a connecting rod 11042 hingedly mounted on the outer wall of the cross sleeve 1101, a T-shaped felt plate 11041 hingedly mounted on the top of the connecting rod 11042, and a vertical block 11043 fixed on the top of the T-shaped felt plate 11041. A notch 11044 is provided on the surface of the support plate 1102 for the vertical block 11043 to pass through. Pulleys 11045 are rotatably mounted on the left and right outer walls of the vertical block 11043. The pulleys 11045 are in rolling contact with the upper surface of the support plate 1102.

[0056] When the support plate 1102 is driven to move downward, since the upright block 11043 is located in the notch 11044 and the pulley 11045 is in contact with the upper surface of the support plate 1102, the downward movement of the support plate 1102 will cause the T-shaped felt plate 11041 to swing downward. In this process, the connecting rod 11042 serves to connect the cross sleeve 1101 and the T-shaped felt plate 11041, so as to adjust the distance between the T-shaped felt plate 11041 and the vertical center axis of the hollow column 10;

[0057] The Z-axis lifting unit 9 includes a main hydraulic cylinder 901 fixed on the top of the C-frame 7 and vertical rods 902 installed on both sides of the top of the support platform 8. The top of the vertical rod 902 extends to the outside of the C-frame 7, and the bottom end of the piston rod of the main hydraulic cylinder 901 is fixedly connected to the top of the support platform 8. During the operation of the adjustable four-way scrubbing module 11, the main hydraulic cylinder 901 drives the support platform 8, the hollow column 10, the adjustable four-way scrubbing module 11 and other components to be lifted and lowered, so as to adjust the working position of the adjustable four-way scrubbing module 11. During this process, the vertical rod 902 improves the lifting stability of the support platform 8, the hollow column 10 and other components, ensures that the module remains stable during the lifting process, and enables the adjustable four-way scrubbing module 11 to act on different positions of the inner cylinder 403.

[0058] Embodiment 4, based on embodiment 3, Fig.10 , Fig.11 and Fig.12 It is given that the gear drive unit 12 includes a second motor 1201 installed on one side of the bottom end of the double-layer hollow sealing cover 6, a driving gear 1202 installed at the output end of the second motor 1201, and a driven double-sided gear ring 1203 rotatably installed at the center position inside the double-layer hollow sealing cover 6, the driving gear 1202 is meshed with the tooth grooves on the outer wall surface of the driven double-sided gear ring 1203, the spline grooves on the inner wall surface of the driven double-sided gear ring 1203 and the splines on the outer wall surface of the outer spline sleeve 1103 cooperate with each other, and the two sides of the bottom end of the double-layer hollow sealing cover 6 are fixed with foot seats 602, and the outer wall of the foot seat 602 is welded to the inner wall of the outer oil filter tank 1;

[0059] When the gear drive unit 12 is working, the rotational power of the second motor 1201 is transmitted to the driven double-sided gear ring 1203 through the driving gear 1202. Since the driven double-sided gear ring 1203 and the external spline sleeve 1103 are in a spline-matched state, the driven double-sided gear ring 1203 allows the external spline sleeve 1103 to rise and fall and slide while maintaining power transmission, thereby allowing the external spline sleeve 1103, the support plate 1102, the connecting rod type adjustable distance cleaning structure 1104 and other components to rotate normally, ensuring the stable operation of the cleaning module. The rotation speed can be adjusted according to actual needs to meet different cleaning requirements.

[0060] When the embodiment of the present application is used, the staff first opens the manhole on the surface of the outer filter oil tank 1, and installs one or more filter membranes on the inner wall of the filter cartridge of the rotating centrifugal module 4, and sends the processed and filtered composite oil for emulsion explosives into the filter cartridge of the rotating centrifugal module 4 through the pumping unit, oil pipe, manhole and other components of the external oil tank. At this time, the composite oil in the filter cartridge is separated from the internal chamber of the outer filter oil tank 1 by the filter membrane. Then the staff starts the rotating centrifugal module 4 through the PLC control panel 13. The rotating centrifugal module 4 uses the principle of centrifugal force to separate the solid impurities and oil in the composite oil through high-speed rotation, that is, the oil rotates at a high speed in the filter cartridge of the rotating centrifugal module 4, and the centrifugal force pushes the impurities and oil together to the filter membrane of the filter cartridge. On the filter membrane, solid impurities are blocked by the filter membrane, while clean oil passes through the filter membrane and flows into the internal chamber of the external filter oil tank 1, and finally converges at the conical tank bottom area of ​​the external filter oil tank 1 through the arc-shaped through cavity 301 of the suspended oil guide platform 3. During the filtering process, the oil active pumping unit 5 is in a working state, which introduces the filtered oil from the inside of the external filter oil tank 1 into the oil storage tank to ensure that the composite oil successfully completes the filtering process. Once the composite oil is filtered, the staff controls the filtering device to enter the cleaning stage. At this time, the staff closes the oil active pumping unit 5 through the PLC control panel 13 and connects the second switch valve 506 to the pump suction end of the external waste liquid through a hose, and removes the filter membrane on the inner wall of the rotating centrifugal module 4 through the manhole. At the same time, the external cleaning liquid can also be sent into the external filter oil tank 1 and the interior of the rotating centrifugal module 4 through the liquid inlet pipe 601. Since the oil active pumping unit 5 is in a closed state, the cleaning liquid will not enter the oil active pumping unit 5 and the subsequent oil storage tank. The staff turns on the Z-axis lifting unit 9 through the PLC control panel 13 to operate. The Z-axis lifting unit 9 drives the support platform 8, the hollow column 10, and the adjustable four-way scrubbing module 11 to move downward until the adjustable four-way scrubbing module 11 is lifted or lowered to the preset position. The support platform 8 and the hollow column 10 provide support and stability in this process to ensure the accurate positioning of the scrubbing module. After the adjustable four-way scrubbing module 11 reaches the cleaning position, the module and the inner wall of the filter cartridge of the rotating centrifugal module 4 The gear drive unit 12 starts to drive the scrubbing module to rotate around the hollow column 10. The design of the four-way scrubbing module 11 with adjustable tension enables it to evenly apply pressure to the filter cartridge of the rotating centrifugal module 4 during rotation, thereby effectively removing impurities and dirt attached to the inner wall of the filter cartridge. During the cleaning process, the adjustable tension mechanism of the module can be automatically adjusted according to the degree of dirt on the inner wall of the filter cartridge, and the Z-axis lifting unit 9 can control the operating position of the four-way scrubbing module 11 with adjustable tension under the operation of the staff, ensuring that the cleaning effect is always in the best state. After the cleaning work is completed, the Z-axis lifting unit 9 drives the support platform 8, the hollow column 10, and the four-way scrubbing module 11 with adjustable tension back to the initial position.Prepare for the next round of filtering operation, and the external waste liquid pumping end actively extracts the waste liquid collected at the bottom of the external filter oil tank 1, and repeats the above cleaning steps several times until the cleaning work is completed.
