Description

Technical Field

[0001] The present application belongs to the field of air purification technology, and specifically relates to a negative oxygen ion filter element. Background Art

[0002] The filter element is a core component of the automobile engine air purifier, used to purify polluted air. Its performance directly affects the treatment effect of the air purifier. Especially in some use scenarios with poor air quality, the air is often filled with dust and other substances. This requires the air to be purified when the engine pneumatic equipment inhales air. The existing filter element cannot adjust the oxygen content in the air when filtering the air, resulting in the air entering the engine and mixing with the oil and gas not reaching the optimal oxygen mixing ratio for diesel combustion. In order to ensure the filtering effect, the filter will even directly adsorb some negative oxygen ions. As a result, incomplete combustion leads to limited power generation. In addition, due to incomplete combustion, there are more carbon monoxide and hydrocarbons in the exhaust emissions, so a method that can supplement and adjust is needed. Summary of the Invention

[0003] In order to solve the problem in the prior art that the oxygen and oxygen ion content of the filtered gas is insufficient and cannot be adjusted, resulting in insufficient combustion of the oil-gas mixture in the engine.

[0004] The technical solutions adopted in this application are:

[0005] A negative oxygen ion filter element comprises a top plate and a bottom cover, wherein the top plate and the bottom cover are connected by a support net, a folded filter screen is provided inside the support net, a negative oxygen ion rope is wrapped around the outside of the folded filter screen, and the intersection of the negative oxygen ion rope is overlapped by a cross buckle.

[0006] Preferably, the cross buckle includes a first cross buckle, the first cross buckle is provided with a rope slide, a progressive wheel is provided in the rope slide, the eaves of the progressive wheel abuts against the negative oxygen ion rope, and to avoid scratching the negative oxygen ion rope, the surface of the progressive wheel adopts a plastic coating layer with a concave and convex gear shape that can increase damping.

[0007] Preferably, the first cross buckle is staggered with a pair of rope slides, which are not connected to each other, and the rope slides are arranged obliquely, and the inclination angles of the pair of rope slides are arranged in a mirror image, and the crossed negative oxygen ion ropes are respectively passed through the pair of rope slides.

[0008] Preferably, a filling groove is provided in the rope slide, the progressive wheel is provided in the filling groove, the rope support assembly is provided with a filling port, the filling port is docked with the filling groove, the filling port is connected to the solvent box containing negative oxygen ions, a small pump body should also be provided between the solvent box and the filling port, the progressive wheel is provided with a docking hole with a keyway, the rope support assembly is provided with a docking shaft, the docking shaft is also provided with a keyway, the docking hole and the docking shaft are detachably connected, the docking shaft is connected to the motor shaft, the motor is provided in the rope support assembly, and a concentration detector is also provided on the rope support assembly, and the concentration detector is electrically connected to the motor.

[0009] Preferably, the top plate and the bottom cover are both provided with annular grooves along the circumference, the negative oxygen ion rope is passed through the annular groove and can slide along the groove wall in the circumferential direction, a docking notch is provided between the annular groove and the support net, and the negative oxygen ion rope passes through the docking notch.

[0010] Preferably, the support net is wound into a cylindrical structure along the circumference of the top plate, and a connected cylindrical air intake cavity is formed inside the cylinder. The folded filter is also wound into a cylindrical structure along the circumference of the top plate.

[0011] Preferably, a second cross buckle is provided on the opposite side of the circumference where the first cross buckle is located, that is, the negative oxygen ion rope on the opposite side of the circumference where the first cross buckle is located will cross again. In order to avoid overlapping friction between the negative oxygen ion ropes, a second cross buckle is required for overlap. The second cross buckle is provided with a pair of rope slides, and the negative oxygen ion rope is passed through the rope slides. Auxiliary pairs of wheels are provided in the rope slides, and the auxiliary pairs of wheels have wheel rims that abut against the negative oxygen ion rope.

[0012] Preferably, the support mesh comprises a unidirectional spiral mesh having side-by-side unidirectional spiral filaments, and further comprises an outer cross-support mesh comprising bidirectional intersecting spiral filaments, the outer cross-support mesh being arranged in a spirally coiled pattern and spaced apart along the outer circumference of the support mesh. The pleated filter is encased within an inner cross-support mesh comprising a unidirectional spiral mesh having side-by-side unidirectional spiral filaments, the inner cross-support mesh being arranged in a spirally coiled pattern and spaced apart along the inner circumference of the pleated filter. To minimize the axial propulsion of filtered air through the gaps between the pleats in the filter element, thereby reducing the filtration effect, the inner cross-support mesh and the outer cross-support mesh are radially staggered, i.e., the inner cross-support mesh radiates outwardly from the unidirectional spiral mesh. Since the outer cross-support mesh presents relatively greater resistance to gas, gas will circumferentially pass through the pleated filter layer and overflow between the unidirectional spiral filaments, which have relatively less resistance. Thus, during the radial overflow process, the gas will generate a certain amount of spiral rotation, increasing the frequency of gas passing through the filter and improving the filtration effect.

[0013] The beneficial effects of this application are: a negative oxygen ion rope is wrapped around the air filter element, and an oxygen ion solvent coating on the negative oxygen ion rope releases oxygen molecules and negative oxygen ions. The concentration of the negative oxygen ion solvent coating can be feedback-regulated according to the oxygen concentration. This increases the oxygen content of the air entering the engine, thereby improving diesel combustion, thereby increasing power. Because combustion is more complete, the content of harmful gases in exhaust emissions is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figure 1 and 2 As shown, a negative oxygen ion filter element includes a top plate 6 and a bottom cover 1, the top plate 6 and the bottom cover 1 are connected by a support net 4, a folded filter screen 5 is provided inside the support net 4, and a negative oxygen ion rope 2 is wrapped around the outside of the folded filter screen 5, and the negative oxygen ion rope 2 is overlapped at the intersection of the winding.

[0022] The implementation method is as follows: the gas to be filtered enters the air intake cavity 8 from the communicating vessel, and after being filtered by the folded filter 5, it overflows from the support net 4. When the airflow overflows, it passes through the negative oxygen ion rope 2, replenishing the filtered gas with oxygen molecules and negative oxygen ions, and then sending it into the engine for full combustion.

[0023] like Figure 1 、 3 As shown in FIG-5 , the cross buckle includes a first cross buckle 3, which is provided with a rope slide 301. A progressive wheel 303 is provided in the rope slide 301. The eaves of the progressive wheel 303 abut against the negative oxygen ion rope 2. To avoid scratching the negative oxygen ion rope 2, the surface of the progressive wheel 303 is coated with a plastic layer with a concave and convex gear shape that can increase damping. The first cross buckle 3 is staggered with a pair of rope slides 301. The pair of rope slides 301 are not connected to each other. The rope slides 301 are arranged at an angle, and the inclination angles of the pair of rope slides 301 are arranged in a mirror image. The intersecting negative oxygen ion ropes 2 are respectively passed through the pair of rope slides 301.

[0024] A filling groove 302 is provided in the rope slide 301, and the progressive wheel 303 is provided in the filling groove 302. The rope support assembly 9 is provided with a filling port 902, and the filling port 902 is docked with the filling groove 302. The filling port 902 is connected to a solvent box containing negative oxygen ions. A small pump body should also be provided between the solvent box and the filling port 902. The progressive wheel 303 is provided with a docking hole 305 with a keyway. The rope support assembly 9 is provided with a docking shaft 901, and the docking shaft 901 is also provided with a keyway. The docking hole 305 and the docking shaft 901 are detachably connected. The docking shaft 901 is connected to the motor shaft. The motor is provided in the rope support assembly 9. A concentration detector 905 is also provided on the rope support assembly 9, and the concentration detector 905 is electrically connected to the motor.

[0025] The support mesh 4 is wound around the circumference of the top plate 6 into a cylindrical structure, with a connected cylindrical air intake cavity 8 formed inside the cylinder. The folded filter 5 is also wound around the circumference of the top plate 6 into a cylindrical structure. The top plate 6 and the bottom cover 1 are both provided with an annular groove 7 along their circumferences. The negative oxygen ion rope 2 is inserted into the annular groove 7 and can slide along the groove wall in the circumferential direction. A docking notch is provided between the annular groove 7 and the support mesh 4. The negative oxygen ion rope 2 is inserted into the docking notch. The negative oxygen ion rope 2 can be wound around the periphery of the support mesh 4 while being able to slide and rotate along the circumference.

[0026] The implementation method is as follows: first, the installation process, the rope support assembly is installed in the engine gas filter box through the installation support foot 904, and multiple ones can be arranged in parallel. When replacing the filter element, align the docking hole 305 on the first cross buckle 3 with the docking shaft 901 and connect it, align the filling port 902 on the first cross buckle 3 with the filling slot 302 and connect it, so that the installation buckle 306 is clamped with the docking buckle 906, and the end cover 903 completes the closure of the rope slide 301 to complete the installation.

[0027] Since the negative oxygen ion solvent coating on the negative oxygen ion rope 2 will gradually dilute and lose its effectiveness after releasing oxygen molecules or oxygen ions, it needs to be replenished in real time. After detecting the oxygen content of the overflowing gas, the concentration detector 905 instructs the solvent box to add or absorb back a portion of the negative oxygen ion solvent into the filling tank 302, and then apply it to the negative oxygen ion rope 2 through the filling tank 302.

[0028] Furthermore, in order to more evenly apply the solvent layer to the negative oxygen ion rope 2, a coating felt 304 is provided at the edge of the filling groove 302. The cross-sectional shape of the coating felt 304 is consistent with the negative oxygen ion rope 2. Under the action of the clamping and rolling of the progressive wheel 303, the negative oxygen ion rope 2 slides obliquely along the circumference, thereby continuously updating the coating concentration on the negative oxygen ion rope 2.

[0029] An optimized implementation is as follows Figure 6 As shown: a second cross buckle 10 is provided on the opposite side of the circumference where the first cross buckle 3 is located, that is, the negative oxygen ion rope 2 on the opposite side of the circumference where the first cross buckle 3 is located will cross again. In order to avoid overlapping friction between the negative oxygen ion ropes 2, a second cross buckle 10 is required for overlap. The second cross buckle 10 is provided with a pair of rope slides 301, and the negative oxygen ion rope 2 is passed through the rope slides 301. Auxiliary pairs of wheels 11 are provided in the rope slides 301, and the eaves of the auxiliary pairs of wheels 11 are in contact with the negative oxygen ion rope 2.

[0030] like Figure 1 and 2 As shown, the support mesh 4 includes a unidirectional spiral mesh 401, which is provided with side-by-side unidirectional spiral wires. The support mesh 4 also includes an outer cross support mesh 402, which includes bidirectional cross spiral wires. The outer cross support mesh 402 is arranged in a spiral shape and spaced along the outer circumference of the support mesh 4. The pleated filter screen 5 is provided with an inner cross support mesh 403. The inner cross support mesh 403 includes a unidirectional spiral mesh 401, which is provided with side-by-side unidirectional spiral wires. The inner cross support mesh 403 is arranged in a spiral shape and spaced along the inner circumference of the pleated filter screen 5. In order to prevent the air to be filtered from advancing axially from the gaps between the pleats in the filter element and reducing the filtering effect, the inner cross-support mesh 403 and the outer cross-support mesh 402 are staggered in the radial direction, that is, the inner cross-support mesh 403 corresponds to the unidirectional spiral mesh 401 in the outward radiation direction. Since the outer cross-support mesh 402 has relatively large resistance to gas, the gas will pass through the five layers of the pleated filter in the circumferential direction and overflow from between the unidirectional spiral wires with relatively small resistance. In this way, the gas will produce a certain spiral rotation during the radial overflow process, which increases the frequency of the gas passing through the filter and improves the filtering effect.
