Description

Technical Field

[0001] The utility model relates to the technical field of carbon canisters, in particular to a carbon canister device for a methanol engine. Background Art

[0002] If the methanol vapor generated by the methanol tank is directly discharged into the atmosphere, it will be neither energy-saving nor environmentally friendly. The current solution is to add a carbon canister to collect the volatile methanol vapor. For example, Chinese utility model publication number CN221647035U discloses a carbon canister structure and layout for a methanol generator set, which can absorb the methanol vapor generated by the methanol tank. When the engine is turned on, the mixed methanol vapor in the carbon canister will participate in combustion, thereby achieving the purpose of saving fuel.

[0003] However, after the carbon canister has been used for a long time, the ash filter will accumulate a lot of dust and impurities, and it needs to be replaced regularly. In addition, after the carbon canister has been used for a long time, the adsorption function of the activated carbon may be weakened, and it also needs to be replaced regularly. However, this technical problem is not solved in the above-mentioned utility model. Most of the existing technical solutions are to set the ash filter on a separate pipeline. The ash filter needs to be removed during maintenance, and the disassembly work is more troublesome. Moreover, after the adsorption function of the activated carbon is weakened, a new carbon canister needs to be replaced. However, the carbon canister body itself is not damaged, and it is a waste to replace all of them. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a carbon canister device for a methanol engine.

[0005] To achieve the above-mentioned purpose, the utility model provides a carbon canister device for a methanol engine, comprising a carbon canister body, an air inlet connected to the carbon canister body, a first pipeline and a second pipeline connected to the carbon canister body, and is characterized in that a base is detachably installed at the bottom of the carbon canister body, a plurality of activated carbon plates are installed in the carbon canister body, and a support plate for placing an ash filter is provided in the carbon canister body; wherein, an elastic part that can eject the ash filter is provided on the support plate.

[0006] Furthermore, a plurality of support rods are fixedly provided on the support plate, the tops of the support rods are fixed to the top wall of the carbon canister body, and a sink for receiving the ash filter is provided on the top surface of the support plate.

[0007] Furthermore, a threaded opening is provided on the carbon canister body, and the ash filter is inserted into the carbon canister body through the threaded opening. A cover is installed on the threaded opening, and the cover is used to press the ash filter into the carbon canister body.

[0008] Furthermore, a first one-way valve is installed on the cover body, and the air inlet is installed on the first one-way valve.

[0009] Furthermore, the ash filter includes a support frame, a multi-fold filter element, a first rubber pad, an air intake pipe and a second rubber pad. The multi-fold filter element is covered on the support frame. A first rubber pad is fixed on the outer periphery of the support frame. The diameter of the first rubber pad is larger than the inner diameter of the threaded opening. The air intake pipe is fixed on the support frame, and the second rubber pad is fixed on the outer periphery of the air intake pipe. The air enters the ash filter through the intake pipe and is discharged after being filtered by the multi-fold filter element.

[0010] Furthermore, a third rubber pad is provided on the inner wall of the cover body, and the third rubber pad can be pressed on the second rubber pad.

[0011] Furthermore, evenly distributed sliding grooves are provided on the inner wall of the carbon canister body, and the activated carbon plate is slidably inserted into the carbon canister body through the sliding grooves.

[0012] Furthermore, a first box body is installed on the carbon canister body, a second one-way valve is fixed on the first box body, and the second one-way valve is communicated with the carbon canister body.

[0013] Furthermore, a solenoid valve is connected to the second one-way valve, and the second pipeline is connected to the solenoid valve.

[0014] Furthermore, a third one-way valve is provided on the first box body, and the third one-way valve can be connected to the carbon canister body, and the first pipeline is connected to the third one-way valve.

[0015] The beneficial effect of the utility model is that the base can be removed from the bottom of the carbon canister body, and a plurality of slide grooves are provided inside the carbon canister body, which can facilitate the sliding insertion of the activated carbon plate, and the replacement or assembly of the activated carbon plate is convenient, fast and time-saving.

[0016] At the same time, the ash filter can also be replaced regularly. The ash filter is installed inside the carbon canister and does not need to be installed outside the carbon canister, so that it forms a whole with the carbon canister, saving external space. When replacing, you only need to unscrew the cover and the carbon canister will pop up, making it easy to take out the ash filter.

[0017] By replacing the activated carbon plate and the ash filter, compared with the traditional technical means of replacing the entire carbon canister, costs are saved. The carbon canister of this application does not need to replace the entire carbon canister, but only needs to regularly replace the activated carbon plate and ash filter inside the carbon canister.

For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0032] The utility model provides a carbon canister device for a methanol engine, comprising a carbon canister body 11, an opening provided at the bottom of the carbon canister body 11, a base 10 spliced ​​and installed at the opening, the base 10 being capable of sealing the bottom opening of the carbon canister body 11, and a sealing ring (not shown) being installed between the connecting gap between the base 10 and the carbon canister body 11 to prevent gas from overflowing.

[0033] In one embodiment, the base 10 and the carbon canister body 11 are compactly spliced ​​together by means of snaps (not shown), which are convenient for installation.

[0034] In another embodiment, the base 10 and the carbon canister body 11 may be fastened together by bolts (not shown). The bolt fastening method is more secure than the snap fastening method.

[0035] A plurality of evenly distributed chutes 33 are provided on the inner wall of the carbon canister body 11. Figure 2As shown, there are two rows of chutes 33, and the two rows of chutes 33 are symmetrically arranged. In this embodiment, there are nine chutes 33 in each row, and the number can be adjusted as needed. The chutes 33 are arranged in long rectangular strips, and an activated carbon plate 32 can be slidably inserted between the two chutes 33. The activated carbon plate 32 is used to adsorb methanol vapor volatilized from the methanol tank.

[0036] Specifically, the chute 33 can be divided into two parts. Figure 2 Taking the example shown, since the left part needs to be installed with an ash filter, the length of the slide groove 33 of the left part can be smaller than the length of the slide groove 33 of the right part, and the number of activated carbon plates 32 can be adjusted according to needs. For example, if the methanol tank is larger, more activated carbon plates 32 can be inserted. If the methanol tank is smaller, the number of activated carbon plates 32 can be appropriately reduced. The sliding insertion method can quickly replace the activated carbon plates 32.

[0037] After the activated carbon plate 32 is inserted, the base 10 is installed at the bottom of the carbon canister body 11, and the carbon canister body 11 is sealed. The activated carbon plate 32 is pressed tightly into the slide groove 33 to prevent the activated carbon plate 32 from shaking in the carbon canister body 11.

[0038] like Figure 2 and Figure 7 As shown, four support rods 27 are fixed inside the carbon canister body 11. The top of the support rod 27 is threaded and screwed into the carbon canister body 11. It can also be demolded as a whole with the carbon canister body 11 during injection molding. A support plate 26 is installed at the bottom of the support rod 27. The support plate 26 and the support rod 27 can be spliced ​​together by snapping. The bottom part of the support rod 27 can also be made thinner in diameter and threaded holes are provided on the bottom surface. The support plate 26 is slidably covered on the bottom part of the four support rods 27, and then four bolts are inserted into the support rod 27 and tightened to fix the support plate 26.

[0039] A downwardly recessed platform 28 is provided on the top surface of the support plate 26 , and the bottom portion of the ash filter can be inserted into the platform 28 .

[0040] In one embodiment, an elastic member 29 is provided in the support plate 26. The elastic member 29 can be pressed into the support plate 26 so that the top surface of the elastic member 29 is flush with the bottom wall of the sink 28. When the ash filter is installed on the support plate 26, the elastic member 29 is stored in the support plate 26.

[0041] Specifically, the elastic member 29 is an elastic telescopic rod, which includes a fixed rod, a movable rod and a spring. The movable rod and the fixed rod are slidably spliced ​​together, and the spring is installed between the fixed rod and the movable rod.

[0042] In another embodiment, the elastic member 29 may be an elastic sheet.

[0043] like Figure 1 and Figure 4 As shown, in one embodiment, a second box body 12 is provided on the top surface of the carbon canister body 11, and the second box body 12 and the carbon canister body 11 are integrally formed by injection molding or casting. A threaded opening 30 is fixed on the top of the second box body 12, and a thread is provided on the outer periphery of the threaded opening 30. A cover body 13 can be tightened on the threaded opening 30 by threading. The middle part of the cover body 13 is provided with an opening, and a first one-way valve 14 is fixed on the top of the cover body 13. The first one-way valve 14 is connected to the air inlet 34. The first one-way valve 14 can prevent the gas in the carbon canister body 11 from overflowing outward through the air inlet 34.

[0044] like Figure 5 As shown, a third rubber pad 31 is provided in the cover body 13 .

[0045] like Figure 3 and Figure 6 As shown, the ash filter includes a multi-fold filter element 21, a first rubber pad 22, a second rubber pad 23, an air intake pipe 24, and a support frame 25, wherein the multi-fold filter element 21 is covered on the outer periphery of the support frame 25, the air intake pipe 24 is fixed on the support frame 25, and the second rubber pad 23 is fixed on the outer periphery of the air intake pipe 24. The diameter of the second rubber pad 23 is the same as that of the third rubber pad 31. A first rubber pad 22 is also fixed on the outer periphery of the support frame 25, and the diameter of the first rubber pad 22 is larger than the inner diameter of the threaded opening 30.

[0046] Specifically, the ash filter is inserted into the threaded opening 30, the first rubber pad 22 is placed on the threaded opening 30, and then the cover body 13 is screwed onto the threaded opening 30. The third rubber pad 31 is pressed against the second rubber pad 23, and the outer periphery of the first rubber pad 22 is pressed against the inner wall of the cover body 13 to seal the connection between the ash filter and the carbon canister body 11. The air intake pipe 24 is inserted into the first one-way valve 14 so that air can only enter from the air inlet 34, pass through the first one-way valve 14, enter the air intake pipe 24, and then pass through the multi-fold filter element 21 to be filtered and enter the carbon canister body 11.

[0047] In one embodiment, a first box body 15 is provided on the top surface of the carbon canister body 11, and a second one-way valve 16 is installed on the first box body 15. The second one-way valve 16 can be connected to the interior of the carbon canister body 11. A solenoid valve 18 is provided on the second one-way valve 16, and a second pipeline 19 is connected to the solenoid valve 18. The second pipeline 19 is connected to the engine, and a filter (not shown) is also installed on the second pipeline 19.

[0048] A third one-way valve 17 is installed on the top surface of the first box body 15 , and a first pipeline 20 is installed on the third one-way valve 17 . The first pipeline 20 can be communicated with the methanol tank to receive the methanol vapor in the tank.

[0049] In one embodiment, two carbon canisters are provided and connected via a pipeline, wherein a first pipeline 20 of one carbon canister is connected to the fuel tank, and a second pipeline 19 of the other carbon canister is connected to the engine.

[0050] The specific workflow is as follows:

[0051] Methanol vapor volatilized from the methanol tank passes through the first pipeline 20 and enters the carbon canister body 11. The third one-way valve 17 prevents the methanol vapor from flowing back and can be adsorbed by the activated carbon plate 32. Air enters the ash filter through the air inlet 34, and then enters the carbon canister body 11 after being filtered by the ash filter, and mixes with the methanol vapor. When the engine is started, the engine generates negative pressure, and the solenoid valve 18 opens at the same time. The methanol vapor and air mixture in the carbon canister body 11 enters the second pipeline 19 through the second one-way valve 16 and is transported to the engine for combustion.

[0052] If the ash filter needs to be replaced, the cover 13 is rotated and removed, and the elastic member 29 bounces the ash filter upward, and the staff removes the ash filter for replacement.

[0053] If the activated carbon plate 32 needs to be replaced, the base 10 can be removed, and then the activated carbon plate 32 to be replaced can be pulled out and replaced with a new activated carbon plate 32, and then the base 10 can be installed.

[0054] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
