Description

Technical Field

[0001] The present invention relates to the field of environmental protection technologies, and particularly to an automatic backwashing and regenerating black smoke purification device. Background Art

[0002] At present, many tail gas treatment products have emerged in the domestic market for waste gas treatment, especially for diesel engine tail gas treatment. Although these products can purify tail gas, they have low efficiency in treating oil engine black smoke, and there are significant problems in terms of the service life, maintenance time, and cost of the products themselves.

[0003] In the prior art, the gas in the gas storage device is often directly blown into the filter element through the backwashing mechanism valve by an air compressor device to blow the black smoke from the filter element into the ash accumulation chamber.

[0004] When directly blowing air into the interior of the filter element, the cleaning effect at positions far from the air outlet of the filter element is limited. Therefore, in the prior art, a blowing air pipe is added, and a number of air outlet holes are added to the blowing air pipe to improve the cleaning effect. However, the air outlet holes need to be spaced apart, resulting in each air outlet hole only blowing air at the same position of the filter element, and the cleaning effect on the part of the filter element interior that is not directly opposite the air outlet holes is still limited.

[0005] Therefore, providing an automatic backwashing and regenerating black smoke purification device that can ensure that every part inside the filter element can be fully cleaned is an urgent problem to be solved by the present invention. Summary of the Invention

[0006] In view of the above technical problems, the object of the present invention is to overcome the limited cleaning effect at positions far from the air outlet of the filter element when directly blowing air into the interior of the filter element. Therefore, in the prior art, a blowing air pipe is added, and a number of air outlet holes are added to the blowing air pipe to improve the cleaning effect. However, the air outlet holes need to be spaced apart, resulting in each air outlet hole only blowing air at the same position of the filter element, and the cleaning effect on the part of the filter element interior that is not directly opposite the air outlet holes is still limited. Thus, an automatic backwashing and regenerating black smoke purification device that can ensure that every part inside the filter element can be fully cleaned is provided.

[0007] To achieve the above object, the present invention provides an automatic backwashing and regenerating black smoke purification device, which includes: a purification chamber, a filter element, a suspension pipe, a rotary wing, and an air compressor gas storage device. A number of filter elements are spaced in the purification chamber. A suspension pipe is vertically arranged coaxially inside the filter element. A wave groove is coaxially and circumferentially arranged in the middle part of the suspension pipe. First air outlet holes are respectively circumferentially arranged on both sides of the suspension pipe relative to the wave groove. A number of jet holes communicating with the first air outlet holes are obliquely arranged along the clockwise or counterclockwise direction on the rotary wing, and a limiting slider adapted to the wave groove is arranged on the inner side thereof. The air compressor gas storage device is arranged on one side of the purification chamber and is communicated with the jet holes through the suspension pipe.

[0008] Preferably, an air inlet is provided on one side of the purification chamber, and a first air outlet is provided at the open top of the filter element where the purification chamber is located.

[0009] Preferably, an ash accumulation chamber is further provided at the bottom of the purification chamber.

[0010] Preferably, the limiting slider is a bearing.

[0011] Preferably, the device further includes a blocking mechanism for blocking the first air outlet.

[0012] Preferably, the blocking mechanism includes: a blocking cover and a reset elastic member. A second air outlet hole is coaxially and circumferentially provided at the open end of the filter element where the suspension pipe is located. The blocking cover is adapted to the first air outlet and is coaxially and reciprocally movably sleeved on the suspension pipe through the reset elastic member. The inside of the blocking cover is communicated with the inside of the suspension pipe through the second air outlet hole.

[0013] Preferably, a first abutting seat and a second abutting seat are coaxially and spaced apart from bottom to top at the open end of the filter element where the suspension pipe is located. The second air outlet hole is coaxially and circumferentially provided above the second abutting seat. One end of the reset elastic member abuts against the upper surface of the first abutting seat, and the other end abuts against the bottom of the blocking cover. The inner bottom of the blocking cover can be abutted against the lower surface of the second abutting seat under the action of the reset elastic member.

[0014] Preferably, when the blocking cover covers the first air outlet, the second air outlet hole can still supply air to the inside of the blocking cover.

[0015] Preferably, a protective cover is provided above the blocking mechanism, and a second air outlet is provided on one side of the protective cover.

[0016] According to the above technical solution, the beneficial effect of the present invention compared with the prior art is as follows: The air compressor storage device in this application is specifically a combined application of an air compressor and a storage tank, which is the prior art. When it is necessary to clean the filter element, the air compressor storage device supplies air to each suspension pipe. The air flow first passes through the first air outlet hole, then enters the rotating wing, and then is discharged through the air spraying holes. Also, due to the cooperation of the wave groove and the limiting slider, the rotating wing will reciprocally move and rotate along the extending direction of the wave groove under the pushing of the air flow ejected from the air spraying holes, so as to ensure that every part inside the filter element can be sprayed by the air flow, improving the cleaning effect.

In addition, terms such as "horizontal", "vertical", "hanging" do not mean that the component is required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0029] In the description of the embodiments of the present invention, it should also be noted that unless otherwise clearly specified and limited, if terms such as "set", "installed", "connected", "linked" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In order to further understand the features, technical means, and specific purposes and functions achieved by the present invention, the present invention will be described in further detail below with reference to the drawings and specific embodiments.

[0031] Refer to Figures 1 - 7 : An automatic back-blowing and regenerating black smoke purification device, the device includes: a purification chamber 1, a filter element 2, a suspension pipe 3, a rotating wing 4, and a pneumatic air storage device 5. A plurality of filter elements 2 are arranged at intervals in the purification chamber 1. A suspension pipe 3 is vertically arranged coaxially inside the filter element 2. A wave groove 301 is coaxially arranged around the middle part of the suspension pipe 3. First air outlet holes 302 are arranged around the suspension pipe 3 on both sides opposite to the wave groove 301. A plurality of air jet holes 401 communicating with the first air outlet holes 302 are arranged obliquely on the rotating wing 4 in the clockwise or counterclockwise direction, and a limit slider 402 adapted to the wave groove 301 is arranged on the inner side thereof. The pneumatic air storage device 5 is arranged on one side of the purification chamber 1 and is communicated with the air jet holes 401 through the suspension pipe 3.

[0032] The air compressor storage device 5 in this application is specifically a combined application of an air compressor and a storage tank, which is a prior art. When it is necessary to clean the filter element 2, the air compressor storage device 5 supplies air to each suspension pipe 3. The air flow first passes through the first air outlet hole 302, then enters the rotating wing 4, and is then discharged through the air injection hole 401. Also, due to the cooperation of the wave groove 301 and the limit slider 402, the rotating wing 4 will reciprocally move and rotate along the extension direction of the wave groove 301 under the push of the air flow ejected from the air injection hole 401, thereby ensuring that every part inside the filter element 2 can be sprayed by the air flow, improving the cleaning effect; the wave groove 301 guides the air flow to flow alternately along the axial and circumferential directions of the filter element 2, avoiding local high-pressure or low-pressure areas, and facilitating the peeling of dust in the internal gaps of the corrugated filter element 301.

[0033] Refer to Figure 2 : An air inlet 101 is provided on one side of the purification chamber 1, and a first air outlet 102 is provided at the top open end of the purification chamber 1 where the filter element 2 is located.

[0034] In this application, the air inlet 101 is connected to the black smoke to be processed, and then the black smoke is discharged into the purification chamber 1 through the air inlet 101. The black smoke is purified through the filter element 2, and the purified black smoke will be discharged from the air outlet; for example, an automobile engine will continuously discharge exhaust gas into the oil-gas separation device, and then discharge the separated gas into the purification chamber 1 for purification.

[0035] Refer to Figure 2 : An ash accumulation chamber 103 is also provided at the bottom of the purification chamber 1.

[0036] In this application, the black ash cleaned inside the filter element 2 will be cleaned into the ash accumulation chamber 103 under the action of the air injection hole 401 of the rotating wing 4. The user can open the ash accumulation chamber 103 regularly to discharge the black ash inside to achieve the cleaning or recycling of the black ash.

[0037] Refer to Figure 7 : The limit slider 402 is a bearing.

[0038] In this application, the rotating wing 4 is clamped into the wave groove 301 through the bearing, so that the movement track of the rotating wing 4 is smoother.

[0039] Refer to Figure 2 : The device further includes a blocking mechanism 6 for blocking the first air outlet 102.

[0040] In this application, when it is necessary to backflush the filter element 2, the first air outlet 102 is blocked by the blocking mechanism 6 to prevent the black ash from being blown out from the first air outlet 102.

[0041] Refer to Figure 6: The plugging mechanism 6 includes: a plugging cover 601 and a reset elastic member 602. A second air outlet 303 is coaxially and circumferentially arranged around the open end of the filter element 2 where the suspension pipe 3 is located. The plugging cover 601 is adapted to the first air outlet 102 and is coaxially and reciprocally movably sleeved on the suspension pipe 3 through the reset elastic member 602. The inside of the plugging cover 601 is communicated with the inside of the suspension pipe 3 through the second air outlet 303.

[0042] In this application, when the air compression and storage device 5 supplies air into the suspension pipe 3, part of the air flow will be injected into the inside of the plugging cover 601 through the second air outlet 303. The plugging cover 601 will compress the reset elastic member 602 under the action of the air flow and move downward until the first air outlet 102 is covered. When the air supply into the suspension pipe 3 stops, the plugging cover 601 will be reset under the action of the reset elastic member 602 to ensure the normal operation of the device.

[0043] Refer to Figure 6 : The suspension pipe 3 is coaxially and spaced apart from bottom to top at the open end of the filter element 2 with a first abutting seat 304 and a second abutting seat 305. The second air outlet 303 is coaxially and circumferentially arranged above the second abutting seat 305. One end of the reset elastic member 602 abuts against the upper surface of the first abutting seat 304, and the other end abuts against the bottom of the plugging cover 601. The inner bottom of the plugging cover 601 can be abutted against the lower surface of the second abutting seat 305 under the action of the reset elastic member 602.

[0044] In this application, the first abutting seat 304 and the second abutting seat 305 are provided to limit the position of the plugging cover 601 to ensure the normal operation of the backwashing function and the purification function of the purification device.

[0045] Refer to Figure 6 : When the plugging cover 601 covers the first air outlet 102, the second air outlet 303 can still supply air to the inside of the plugging cover 601.

[0046] Through this design in this application, when the plugging cover 601 covers the first air outlet 102, it is prevented that the second air outlet 303 is blocked by the plugging cover 601 or air is supplied outside the plugging cover 601, resulting in the plugging cover 601 being unable to effectively cover the first air outlet 102 for a long time.

[0047] Refer to Figure 2 and Figure 5 : A protective cover 7 is provided above the plugging mechanism 6. A second air outlet 701 is provided on one side of the protective cover 7.

[0048] In this application, the protective cover 7 is provided to prevent dirt from falling into the inside of the filter element 2 from the first air outlet 102, and then the purified black smoke is discharged through the second air outlet 701.

[0049] When the device provided by the present invention needs to clean the filter element 2, the air compressor air storage device 5 supplies air to each suspension pipe 3. The air flow first passes through the first air outlet hole 302, then enters the rotating wing 4, and then is discharged through the air spraying hole 401. Also, due to the cooperation of the wave groove 301 and the limit slider 402, the rotating wing 4 will reciprocate and rotate along the extending direction of the wave groove 301 under the push of the air flow ejected from the air spraying hole 401, so as to ensure that every part inside the filter element 2 can be sprayed by the air flow, improving the cleaning effect.

[0050] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0051] In addition, it should be noted that for each specific technical feature described in the above specific embodiments, without contradiction, they can be combined in any appropriate way. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.

[0052] In addition, any combination can be made between various different embodiments of the present invention, as long as it does not violate the idea of the present invention, it should also be regarded as the content disclosed by the present invention.
