Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a methanol fuel additive filtration device. Background Technology

[0002] Methanol fuel additives are chemical additives used to improve the performance of methanol fuel. During the production and use of methanol fuel additives, various impurities and particulate matter may be mixed in. These impurities not only affect the combustion efficiency of the fuel, but may also cause equipment blockage, performance degradation or even damage. Therefore, filtration can effectively remove these impurities and ensure the purity and stability of the fuel.

[0003] Chinese utility model patent CN221513661U discloses a liquid filtration device for a material production line, including a filtration assembly and a cleaning assembly. The filtration assembly includes a housing; a top cover is connected to the upper surface of the housing; an inlet pipe is connected to the left side of the outer side wall of the housing; an outlet hopper is connected to the lower surface of the housing; a waste discharge pipe is connected to the left side of the lower surface of the housing; a fixing ring is welded to the lower side of the inner side wall of the housing; a filter screen is provided on the upper surface of the fixing ring; the cleaning assembly includes a motor, which is located on the upper side of the top cover; a drive shaft is provided on the inner side of the connecting block; the outer side wall of the drive shaft is rotatably connected to the inner side wall of the top cover; the upper end of the drive shaft is fixedly connected to the output end of the motor; a limiting ring is provided on the outer side wall of the fixing ring; a uniformly distributed connecting rod is welded between the upper surface of the limiting ring and the lower surface of the connecting block; an arc-shaped scraper is installed on the side of the connecting rod near the filter screen; and a pusher plate is fixedly connected to the lower surface of the limiting ring.

[0004] During the cleaning process of the filter cylinder, the above-mentioned filtration device uses an arc-shaped scraper to move up and down along the side wall of the filter cylinder and scrape off the impurities attached to the side wall of the filter cylinder. Some particles that are partially stuck in the filter holes of the filter cylinder may become stuck in the filter holes due to the squeezing of the arc-shaped scraper, thereby increasing the probability of filter cylinder clogging. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a methanol fuel additive filtration device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a methanol fuel additive filtration device, comprising a filter box and a feed pipe that is fixedly disposed at the top of the filter box, a plurality of support legs fixed at the bottom of the filter box for supporting it, a filter barrel coaxially disposed on the inner top wall of the filter box, a plurality of filter holes being disposed through the side wall of the filter barrel, an annular baffle slidably sleeved on the side wall of the filter barrel at the position below the filter holes, the outer side wall of the annular baffle abutting against the inner side wall of the filter box, a drain pipe fixed and connected to the bottom of the filter box, a flushing mechanism for flushing the inner wall of the filter barrel, a height adjustment mechanism for driving the annular baffle to rise and fall on the filter box, and a discharge assembly for discharging the filtered methanol fuel additive on the filter barrel.

[0007] By adopting the above technical solution, during the cleaning process of the filter cartridge, the height adjustment mechanism drives the annular baffle to descend until the annular baffle separates from the filter cartridge. At this time, the flushing mechanism flushes the inner wall of the filter cartridge. The water flow passes through the filter holes on the filter cartridge and washes the particles off the filter cartridge. The water flow with particles flows through the gap between the annular baffle and the filter cartridge to the bottom of the filter box, and finally is discharged into the filter box through the drain pipe. This avoids the situation in the prior art where particles are squeezed into the filter holes when the filter cartridge is scraped off, which causes the filter cartridge to become clogged, and reduces the probability of filter cartridge clogging.

[0008] Furthermore, the rinsing mechanism includes a rinsing assembly, which includes an inlet pipe that is slidably disposed on the top of the filter box, a rinsing box that is fixed to and connected to the lower end of the inlet pipe, and a water supply hose that is fixed to and connected to the upper end of the inlet pipe. The rinsing box has a ring structure and is located inside the filter barrel and coaxially disposed with the filter barrel. Multiple rinsing holes are provided through the outside of the rinsing box. The rinsing mechanism also includes a lifting assembly for driving the rinsing box to rise and fall.

[0009] By adopting the above technical solution, during the cleaning process of the filter canister, the water source is connected to the water supply hose. First, the water flows into the inlet pipe through the water supply hose, then into the rinsing tank through the inlet pipe, and finally out of the rinsing hole into the rinsing tank to rinse the inner wall of the filter canister. At the same time, the rinsing tank can be raised or lowered by the lifting component to rinse the entire inner wall of the filter canister, ensuring the cleaning of the filter canister.

[0010] Furthermore, the lifting assembly includes a screw that passes through and slides into the top of the filter box, an internally threaded sleeve that is rotatably mounted on the top of the filter box and threadedly connected, a driven gear fixedly sleeved on the internally threaded sleeve, a mounting plate fixed to the top of the filter box, a lifting motor fixed to the mounting plate, and a driving gear fixedly sleeved on the output end of the lifting motor and meshing with the driven gear. The lower end of the screw is fixed to the top of the rinsing box.

[0011] By adopting the above technical solution, after the lifting motor works, it drives the drive gear to rotate, which causes the driven gear meshing with the drive gear and the internal threaded sleeve connected to the driven gear to rotate. Since the screw is threadedly connected to the internal threaded sleeve and the screw is fixedly connected to the rinsing box, the screw drives the rinsing box to rise or fall, so as to ensure the cleaning effect on the filter barrel.

[0012] Furthermore, the height adjustment mechanism includes a height adjustment assembly, which includes a vertical rod fixed to the top of the annular baffle and a sleeve slidably fitted onto the vertical rod. The sleeve passes through the top of the filter box and is slidably engaged. The height adjustment assembly also includes a horizontal plate fixed to the side wall of the sleeve and fixedly connected to a screw, and a slider fixed to the side wall of the vertical rod near the top of the vertical rod. The side wall of the sleeve is provided with a sliding groove that is slidably connected to the slider. The horizontal plate is fixedly connected to the water inlet pipe. The height adjustment mechanism also includes a sealing assembly for improving the sealing effect of the annular baffle.

[0013] By adopting the above technical solution, during the screw lifting process, the horizontal plate fixed to the screw, the sleeve fixed to the horizontal plate, the vertical rod connected to the sleeve, and the annular baffle connected to the vertical rod all rise or fall. During the descent of the horizontal plate, the annular baffle first descends and contacts the inner bottom wall of the filter box. At this time, due to the limiting effect of the filter box on the annular baffle, the annular baffle and the vertical rod are in a stationary state, while the sleeve will continue to descend with the horizontal plate until the lower end of the horizontal plate abuts against the top of the annular baffle, ensuring the normal sewage discharge operation of the device.

[0014] Furthermore, the sealing assembly includes an annular stop block fixed to the inner wall of the filter box, a sealing stop block with an annular structure fixed to the outer wall of the filter barrel, and a limiting block fixed to the inner bottom wall of the filter box and located below the annular baffle. The bottom of the annular stop block abuts against the top of the annular baffle near the filter box, and the bottom of the sealing stop block abuts against the top of the annular baffle near the filter barrel.

[0015] By adopting the above technical solution, the setting of the annular baffle and the sealing baffle reduces the probability that methanol fuel additive will flow from between the annular baffle and the filter barrel and between the annular baffle and the filter box to the bottom of the filter box and be discharged from the drain pipe when filtering methanol fuel additive.

[0016] Furthermore, the filter box is equipped with a water supply assembly, which includes a filter tank fixed to the support leg and located below the filter box, a water pump fixed to the side wall of the filter tank, a water pump pipe fixed to and connected to the input end of the water pump, a drain pipe fixed to and connected to the output end of the water pump, and a filter screen fixed inside the filter tank and located above the water pump pipe. The end of the water pump pipe away from the water pump passes through the side wall of the filter tank and is fixed. A water pumping hole is provided through the side wall of the water pump pipe. The drain pipe passes through the top of the filter tank and is fixed. The upper end of the drain pipe is fixed to and connected to the lower end of the water supply hose.

[0017] By adopting the above technical solution, during the cleaning process of the filter tank, the sewage is discharged into the water filter tank through the drain pipe. The filter screen filters the sewage, and the filtered water flows to the inner bottom wall of the water filter tank. At this time, after the water pump works, the water first flows into the water pump through the pump pipe, then the water flows from the output end of the water pump to the drain pipe, and finally it is discharged into the water delivery hose through the drain pipe, realizing the recycling of water resources and reducing the waste of water resources.

[0018] Furthermore, the discharge assembly includes a pump fixed to the filter tank, a feed pipe fixed to and connected to the input end of the pump, and a discharge pipe fixed to and connected to the output end of the feed pipe. The feed pipe extends into the filter tank, and the upper end of the feed pipe is connected to the filter barrel. A fixed pipe is fixed to and connected to the side wall of the discharge pipe. A solenoid valve is installed on the fixed pipe, and a solenoid valve is also installed at the end of the discharge pipe away from the pump.

[0019] By adopting the above technical solution, during the filter tank cleaning process, the solenoid valve on the discharge pipe is closed, and the solenoid valve on the fixed pipe is opened. Simultaneously, after the pump operates, the water sprayed from the rinsing tank first flows from the inlet pipe to the input end of the pump, then from the output end of the pump to the discharge pipe, and finally flows through the fixed pipe into the filter tank for filtration and reuse, ensuring the normal recycling of wastewater by the water supply components. During normal discharge, the solenoid valve on the discharge pipe is opened, and the solenoid valve on the fixed pipe is closed. Simultaneously, after the pump operates, the methanol fuel additive inside the filter tank passes sequentially through the inlet pipe, the pump, and the discharge pipe, finally being discharged to the required location, ensuring the normal filtration operation of the filtration device.

[0020] Furthermore, the filter barrel is rotatably installed on the inner top wall of the filter box, and a connecting pipe fixed to the bottom of the filter barrel is provided through the inner bottom wall of the filter barrel. The lower end of the connecting pipe is rotatably installed on the upper end of the feed pipe through a rotating shaft seal. A rotating motor that drives the connecting pipe to rotate is fixed on the top of the filter box, and a water inlet hole is provided through the side wall of the connecting pipe.

[0021] By adopting the above technical solution, the rotating motor drives the connecting pipe to rotate after it starts working, which in turn causes the filter barrel fixed to the connecting pipe to rotate. During the rinsing process of the filter barrel, the centrifugal force generated by the rotation of the filter barrel helps to increase the speed at which particulate matter is separated from the filter holes.

[0022] In summary, the present invention has the following beneficial effects: In this application, by setting a rinsing mechanism, the existing technology avoids the situation where the particles are squeezed into the filter holes when the particles are scraped off the filter cartridge, which causes the filter cartridge to become clogged, thus reducing the probability of filter cartridge clogging.

Detailed Implementation

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] like Figure 1-5 As shown in the illustration, this application discloses a methanol fuel additive filtration device, including a filter box 1, a flushing mechanism 6, a height adjustment mechanism 7, a discharge assembly 8, and a water supply assembly 9. A feed pipe 2 is installed through and fixed to the top of the filter box 1. Multiple support legs are fixed to the bottom of the filter box 1 for support. A filter barrel 3, coaxially arranged with the filter box 1, is installed on the inner top wall of the filter box 1. Multiple filter holes are provided through the side wall of the filter barrel 3. An annular baffle 4, located below the filter holes, is slidably fitted onto the side wall of the filter barrel 3. The outer side wall of the annular baffle 4 abuts against the inner side wall of the filter box 1. A drain pipe 5 is fixed to and connected to the bottom of the filter box 1.

[0031] A rinsing mechanism 6 is installed inside the filter barrel 3 and is used to rinse the inner wall of the filter barrel 3. The rinsing mechanism 6 includes a rinsing assembly 61 and a lifting assembly 62. The rinsing assembly 61 includes an inlet pipe 611, a rinsing tank 612, and a water delivery hose 613. The inlet pipe 611 passes through the top of the filter barrel 1 and is slidably fitted. The rinsing tank 612 is fixed to the lower end of the inlet pipe 611 and is connected to it. The rinsing tank 612 has a ring structure and is located inside the filter barrel 3 and coaxially arranged with the filter barrel 3. Multiple rinsing holes 614 are provided through the outer side of the rinsing tank 612. The water delivery hose 613 is fixed to and connected to the upper end of the inlet pipe 611.

[0032] The lifting assembly 62 is used to drive the rinsing tank 612 to rise and fall. The lifting assembly 62 includes a screw 621, an internally threaded sleeve 622, a driven gear 623, a mounting plate 624, a lifting motor 625, and a driving gear 626. The screw 621 passes through the top of the filter box 1 and is slidably engaged. The lower end of the screw 621 is fixed to the top of the rinsing tank 612. The internally threaded sleeve 622 is rotatably mounted on the top of the filter box 1 and threadedly connected. The driven gear 623 is fixedly sleeved on the internally threaded sleeve 622. The mounting plate 624 is fixed to the top of the filter box 1. The lifting motor 625 is fixed to the mounting plate 624. The driving gear 626 is fixedly sleeved on the output end of the lifting motor 625 and meshes with the driven gear 623.

[0033] During the filtration process in filter box 1, the methanol fuel additive with filter is introduced into filter box 1 through feed pipe 2. Due to the obstruction of annular baffle 4, the methanol fuel additive enters filter barrel 3 through filter holes, while particulate matter is blocked outside filter barrel 3. At this time, the clean methanol fuel additive can be discharged from filter barrel 3 through discharge assembly 8. During the cleaning process of filter barrel 3, annular baffle 4 is driven down by height adjustment mechanism 7 until annular baffle 4 separates from filter barrel 3. At this time, water source is connected to water supply hose 613. First, water flows from water supply hose 613 into water inlet pipe 611, then from water inlet pipe 611 into flushing tank 612, and finally discharged from flushing hole 614 into flushing tank 612. At the same time, after the lifting motor 625 is working, it drives the drive gear 626 to rotate, causing the driven gear 623 meshing with the drive gear 626 and the internal threaded sleeve 622 connected to the driven gear 623 to rotate. Due to the screw 6 21 is threadedly connected to the internal threaded sleeve 622, and the screw 621 is fixedly connected to the flushing box 612, so that the screw 621 drives the flushing box 612 to rise or fall and flush the inner wall of the filter barrel 3. The water flow will pass through the filter holes on the filter barrel 3 and flush the particles from the filter holes away from the filter barrel 3. The water flow with particles will flow through the gap between the annular baffle 4 and the filter barrel 3 to the bottom of the filter box 1, and finally be discharged into the filter box 1 through the drain pipe 5. This avoids the situation in the prior art where the particles are squeezed into the filter holes when the filter barrel is scraped off, which causes the filter barrel to become blocked, and reduces the probability of filter barrel blockage.

[0034] A height adjustment mechanism 7 is installed on the filter box 1, and is used to drive the annular baffle 4 to rise and fall. The height adjustment mechanism 7 includes a height adjustment component 71 and a sealing component 72. The height adjustment component 71 includes a vertical rod 711, a sleeve 712, a horizontal plate 713, and a slider 714. The vertical rod 711 is fixed to the top of the annular baffle 4, and the sleeve 712 is slidably fitted onto the vertical rod 711. The sleeve 712 passes through the top of the filter box 1 and is slidably engaged. The horizontal plate 713 is fixed to the side wall of the sleeve 712 and is fixedly connected to the screw 621. The horizontal plate 713 is fixedly connected to the water inlet pipe 611. The slider 714 is fixed to the side wall of the vertical rod 711 near the top of the vertical rod 711. A groove 715 is provided through the side wall of the sleeve 712 and is slidably connected to the slider 714.

[0035] During the lifting and lowering process of the screw 621, the horizontal plate 713 fixed to the screw 621, the sleeve 712 fixed to the horizontal plate 713, the vertical rod 711 connected to the sleeve 712, and the annular baffle 4 connected to the vertical rod 711 all rise or fall. During the descent of the horizontal plate 713, the annular baffle 4 first descends and contacts the inner bottom wall of the filter box 1. At this time, due to the limiting effect of the filter box 1 on the annular baffle 4, the annular baffle 4 and the vertical rod 711 are in a stationary state, while the sleeve 712 will continue to descend with the horizontal plate 713 until the lower end of the horizontal plate 713 abuts against the top of the annular baffle 4, to ensure the normal sewage discharge operation of the device.

[0036] The sealing assembly 72 is used to improve the sealing effect of the annular baffle 4. The sealing assembly 72 includes an annular block 721, a sealing block 722, and a limiting block 723. The annular block 721 is fixed to the inner wall of the filter box 1, and the bottom of the annular block 721 abuts against the top of the annular baffle 4 near the filter box 1. The sealing block 722 is fixed to the outer wall of the filter barrel 3 and has an annular structure. The bottom of the sealing block 722 abuts against the top of the annular baffle 4 near the filter barrel 3. The limiting block 723 is fixed to the inner bottom wall of the filter box 1 and is located below the annular baffle 4.

[0037] The arrangement of the annular baffle 721 and the sealing baffle 722 reduces the probability that the methanol fuel additive will flow from between the annular baffle 4 and the filter barrel 3 and between the annular baffle 4 and the filter box 1 to the bottom of the filter box 1 and be discharged from the drain pipe 5 when filtering the methanol fuel additive.

[0038] A discharge assembly 8 is mounted on the filter tank 3 and is used to discharge the filtered methanol fuel additive. The discharge assembly 8 includes a pump 81, a feed pipe 82, and a discharge pipe 83. The pump 81 is fixed to the filter tank 91. The feed pipe 82 is fixed to and connected to the input end of the pump 81, extends into the filter tank 1, and its upper end connects to the inside of the filter tank 3. The discharge pipe 83 is fixed to and connected to the output end of the feed pipe 82, and a fixed pipe is fixed to and connected to the side wall of the discharge pipe 83. A solenoid valve is installed on the fixed pipe, and a solenoid valve is also installed at the end of the discharge pipe 83 furthest from the pump 81.

[0039] During the cleaning of filter tank 3, the solenoid valve on discharge pipe 83 is closed, and the solenoid valve on fixed pipe is opened. Simultaneously, after pump 81 starts operating, the water sprayed from flushing tank 612 first flows from inlet pipe 82 to the input end of pump 81, then from the output end of pump 81 to discharge pipe 83, and finally from fixed pipe into water tank 91 for filtration and reuse, ensuring the normal recycling of wastewater by water supply component 9. During normal discharge, the solenoid valve on discharge pipe 83 is opened, and the solenoid valve on fixed pipe is closed. Simultaneously, after pump 81 starts operating, the methanol fuel additive inside filter tank 3 passes sequentially through inlet pipe 82, pump 81, and discharge pipe 83, finally being discharged to the required location, ensuring the normal filtration operation of the filtration device.

[0040] A water supply assembly 9 is mounted on the filter box 1. The water supply assembly 9 includes a filter tank 91, a water pump 92, a water pump 92, a water pump 92, a water pump 93, a water drain pipe 94, and a filter screen 95, all fixed to the support legs and located below the filter box 1. A drain pipe 5 passes through the top of the filter tank 91 and is fixed thereto. The filter tank 91 is fixed to the side wall of the filter tank 91. The water pump 93 is fixed and connected to the input end of the water pump 92. The end of the water pump 93 away from the water pump 92 passes through the side wall of the filter tank 91 and is fixed thereto. A water pumping hole is provided through the side wall of the water pump 93. The drain pipe 94 is fixed and connected to the output end of the water pump 92. The upper end of the drain pipe 94 is fixed and connected to the lower end of the water delivery hose 613. The filter screen 95 is fixed inside the filter tank 91 and located above the water pump 93.

[0041] During the cleaning process of filter tank 3, sewage is discharged into water filter tank 91 through drain pipe 5. Filter screen 95 filters the sewage, and the filtered water flows to the inner bottom wall of water filter tank 91. At this time, after water pump 92 is working, water first flows into water pump 92 through water pump pipe 93, then water flows from the output end of water pump 92 to drain pipe 94, and finally water is discharged from drain pipe 94 into water delivery hose 613, realizing the recycling of water resources and reducing water waste.

[0042] The filter barrel 3 is rotatably mounted on the inner top wall of the filter box 1. A connecting pipe 10, fixed to the bottom of the filter barrel 3, is installed through the inner bottom wall of the filter barrel 3. The lower end of the connecting pipe 10 is rotatably mounted to the upper end of the feed pipe 82 via a rotating shaft seal. A water inlet hole is provided through the side wall of the connecting pipe 10. A rotary motor 11, which drives the connecting pipe 10 to rotate, is fixed on the top of the filter box 1. After the rotary motor 11 is working, it drives the connecting pipe 10 to rotate, causing the filter barrel 3, which is fixed to the connecting pipe 10, to rotate. During the rinsing process of the filter barrel 3, the centrifugal force generated by the rotation of the filter barrel 3 helps to increase the speed at which particulate matter separates from the filter holes.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
