[0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to a blowing and cleaning device and automatic filter cleaning equipment having the blowing and cleaning device. Background Art

[0002] Currently on the market, filters are a common device for filtering liquids or gases and are widely used in the fields of petroleum, chemical, automobile, shipbuilding, aerospace, etc.

[0003] At present, filter cleaning is generally done manually using compressed air. During the operation, there are disadvantages such as low efficiency, poor quality, threat to personnel health, and environmental pollution. In particular, many filters in the cabin equipment have different sizes and structures. Manual cleaning is time-consuming and laborious, and there are many dead corners and blind spots. The cleaning quality is not high, and there is a risk of being injured by compressed air. In addition, when cleaning the filter manually, oil, gas and pollutants are easy to run around, causing the entire cabin environment to be polluted.

[0004] Therefore, it is urgent to design a blowing and cleaning device to solve the following deficiencies of the above technical solution in actual use: the existing filter blowing and cleaning operations mostly use manual blowing and cleaning of the filter, which has the problems of low work efficiency and easy pollution of the working environment. Summary of the invention

[0005] The purpose of the embodiments of the present invention is to provide a blowing and cleaning device and an automatic filter cleaning device having the blowing and cleaning device, so as to solve the problem that the existing filter blowing and cleaning operations mentioned in the above background technology mostly adopt manual blowing and cleaning of the filter, which has low work efficiency and is easy to pollute the working environment.

[0006] The embodiment of the present invention is implemented as follows: a purge device includes a housing and further includes:

[0007] A purge mechanism, the purge mechanism comprising a mounting base arranged inside the housing, the mounting base being rotatably connected to a mounting seat for placing an object to be cleaned via a rotating member, and a third purge port for delivering compressed gas to purge the object to be cleaned is provided in the mounting base;

[0008] a distribution chamber, for delivering compressed gas to the purge mechanism to purge the object to be cleaned, and delivering compressed gas to a drive pipeline disposed in the housing, wherein an output end of the drive pipeline is connected to a drive nozzle for blowing the rotating member to drive the mounting seat to rotate; and

[0009] The recovery mechanism is connected to the outer side of the shell and is used for extracting impurities in the shell.

[0010] In another embodiment of the present invention, there is also provided an automatic filter cleaning device, comprising the above-mentioned blowing device, and the automatic filter cleaning also includes: an electrical control box, arranged at the upper end of the distribution chamber, for controlling the distribution chamber to deliver compressed gas to the blowing mechanism to blow the object to be cleaned, and delivering compressed gas to the driving pipeline to blow the rotating part to drive the mounting seat to rotate; the electrical control box is also connected to the recovery mechanism signal, for driving the recovery mechanism to extract impurities in the shell.

[0011] Compared with the prior art, the purge device provided in the embodiment of the present invention comprises a shell, a purge mechanism, a recovery mechanism for extracting impurities in the shell, and a distribution chamber for conveying compressed gas to the purge mechanism to purge the object to be cleaned. The purge mechanism comprises a mounting base, on which a mounting seat is rotatably connected via a rotating member. The distribution chamber also conveys compressed gas to a driving pipeline for blowing the rotating member to drive the mounting seat to rotate; the compressed gas is conveyed to the driving pipeline through the distribution chamber to blow the rotating member to drive the mounting seat to rotate, and at the same time, the compressed gas is conveyed to the purge mechanism to purge the object to be cleaned in cooperation with the distribution chamber.

[0021] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0022] like Figure 1-2 FIG. 1 is a structural diagram of a purging device provided by an embodiment of the present invention, wherein the purging device comprises a housing 3 and further comprises:

[0023] A purge mechanism 1, the purge mechanism 1 comprises a mounting base 2 arranged inside the housing 3, a mounting base 7 for placing an object to be cleaned is rotatably connected to the mounting base 2 via a rotating member 5, and a third purge port 6 for delivering compressed gas to purge the object to be cleaned is provided in the mounting base 2;

[0024] a distribution chamber 12, for delivering compressed gas to the purge mechanism 1 to purge the object to be cleaned, and delivering compressed gas to a drive pipeline 8 disposed in the housing 3, wherein an output end of the drive pipeline 8 is connected to a drive nozzle 9 for blowing the rotating member 5 to drive the mounting seat 7 to rotate; and

[0025] The recovery mechanism 18 is connected to the outer side of the shell 3 and is used to extract impurities in the shell 3 .

[0026] In an embodiment of the present invention, compressed gas is delivered to the driving pipeline 8 through the distribution chamber 12 to blow the rotating part 5 to drive the mounting seat 7 to rotate, and at the same time, the compressed gas is delivered to the blowing mechanism 1 in cooperation with the distribution chamber 12 to blow the object to be cleaned. Compared with traditional manual blowing, the blowing efficiency can be effectively improved, and 360-degree blowing without dead ends can be achieved. The oil mist and other impurities generated during cleaning are also recovered through the recovery mechanism 18, thereby avoiding the harm of oil mist inhalation to the operator, and solving the problem that most of the existing filter blowing operations use manual blowing of filters, which has low working efficiency and easy pollution of the working environment.

[0027] In one embodiment of the present invention, the compressed gas can be high-pressure air formed by compression, or other compressed gases, for example, nitrogen, carbon dioxide, etc. The specific selection can be based on the working operation requirements of the object to be cleaned and the gas environment required by the working environment, and is not limited here.

[0028] In another example of the present invention, the purging device also includes: an electrical control box 13, which is arranged at the upper end of the distribution chamber 12, and is used to control the distribution chamber 12 to deliver compressed gas to the purging mechanism 1 to purge the object to be cleaned, and deliver compressed gas to the driving pipeline 8 to blow the rotating part 5 to drive the mounting seat 7 to rotate; the electrical control box 13 is also connected to the recovery mechanism 18 signal, and is used to drive the recovery mechanism 18 to extract impurities in the shell 3.

[0029] It should be noted that the distribution chamber 12 may be an air distribution bag in the prior art, or may be directly connected to an external air compression device.

[0030] Furthermore, as a preferred embodiment of the present invention, the output end of the third purge port 6 passes through the mounting base 2, the rotating member 5 and the mounting seat 7 in sequence and extends out, and the output direction of the third purge port 6 is along a direction parallel to the mounting seat 7 or along a direction perpendicular to the mounting seat 7.

[0031] In the embodiment of the present invention, the object to be cleaned disposed on the mounting seat 7 can be cleaned through the third cleaning port 6 in a direction parallel to the mounting seat 7 or in a direction perpendicular to the mounting seat 7 .

[0032] In one embodiment of the present invention, the rotating member 5 can be a rolling bearing, and a plurality of driving blades 11 are fixedly mounted on the outer side of the rolling bearing. The shape of the driving blades 11 is not specifically limited. For example, the shape of the driving blades 11 can be a rectangular parallelepiped, a cylinder, or a fan-shaped one. The shape is not specifically limited, but a fan-shaped one is preferred. By aligning the output end of the driving nozzle 9 with the driving blades 11, the compressed air in the distribution chamber 12 can be blown out and blow the rolling bearing to rotate. Since it is composed of a rolling bearing and a mounting seat 7 (which can be a chassis), the driving blades 11 are aligned with a driving nozzle 9, and the driving nozzle 9 is connected to the driving pipeline 8 via a copper tube. When the compressed air is sprayed toward the driving blades 11 through the driving nozzle 9, the mounting seat 7 rotates, thereby driving the filter placed on the mounting seat 7 to rotate, and cooperating with the third blowing port 6 to blow the filter.

[0033] In another example of the present invention, the output end of the third purge port 6 passes through the mounting base 2, the rotating member 5 and the mounting seat 7 in sequence and extends out. The rotating member 5 can be a rolling bearing, and the hollow space of the inner ring of the rolling bearing can allow the output end of the third purge port 6 to pass through without affecting the rotation of the rolling bearing.

[0034] In another example of the present invention, the third purge port 6 in the purge mechanism 1 can be a nozzle in the prior art, specifically a bottom nozzle, the bottom nozzle is connected to the third air inlet pipe 4, and generally, the bottom nozzle is a disc-type upward jet nozzle, which is suitable for disc-type filters and filters that filter from the inside out, and can purge the object to be cleaned from the inside out, so as to achieve purge of the object to be cleaned arranged on the mounting seat 7 in a direction perpendicular to the mounting seat 7. When the filter filter is filtered from the outside to the inside, a column-type nozzle tooling can be added to the bottom nozzle to achieve the purpose of reverse purge, and then the object to be cleaned arranged on the mounting seat 7 is purge in a direction parallel to the mounting seat 7.

[0035] Furthermore, as a preferred embodiment of the present invention, an auxiliary blowing component for blowing the outside of the object to be cleaned is also provided on the inner wall of the shell 3.

[0036] In the embodiment of the present invention, the outside of the object to be cleaned can be cleaned by the auxiliary cleaning component, and then the third cleaning port 6 can be cooperated to realize synchronous cleaning from the inside to the outside.

[0037] Further, as a preferred embodiment of the present invention, the auxiliary purge assembly comprises:

[0038] A frame 17 fixed on the inner wall of the housing 3; and

[0039] A second purge port 14 is installed on the frame 17 , and the output direction of the second purge port 14 is along a direction parallel to the mounting seat 7 , the input end of the second purge port 14 is connected to the distribution chamber 12 , and the distribution chamber 12 is also connected to the input end of the drive pipeline 8 .

[0040] In one example of the present invention, when the filter is filtered from the outside to the inside, the input end of the second flushing port 14 is connected to the distribution chamber 12, and compressed gas is delivered to the second flushing port 14 through the distribution chamber 12, thereby achieving the purpose of reverse flushing, thereby flushing the object to be cleaned arranged on the mounting seat 7 along a direction parallel to the mounting seat 7.

[0041] Further, as a preferred embodiment of the present invention, the second purge port 14 comprises:

[0042] The output end faces the second purge port body away from one end of the frame 17;

[0043] A partition 10 installed in the second purge port body, used to divide the interior of the second purge port body into a first chamber and a second chamber;

[0044] A first air inlet pipeline 15, one end of which is connected to the first chamber, and the other end of which is connected to the distribution chamber 12; and

[0045] One end of the second air inlet pipeline 16 is connected to the second chamber, and the other end is connected to the distribution chamber 12 .

[0046] In the embodiment of the present invention, by separately or simultaneously controlling the opening and closing of the first air inlet pipeline 15 and the second air inlet pipeline 16, it is possible to separately or simultaneously deliver compressed gas to the first chamber and the first chamber inside the second purge port body, and external purge can be performed on filters of different types as needed. Filters of different sizes and structures can be purge, and the purge time can be shortened to thoroughly blow away residual liquid and contaminants on the filter, and the technical level of the operator is not required to be high.

[0047] In one example of the present invention, the second purge port body is a column-type nozzle, which is arranged in the shell 3, and the frame 17 is an adjustable bracket. The second purge port body is connected to the inner wall of the shell 3 through the adjustable bracket. The isolation member 10 divides the column-type nozzle into two upper and lower parts. The first air inlet pipe 15 is connected to the first chamber at one end and connected to the distribution chamber 12 at the other end. The second air inlet pipe 16 is connected to the second chamber at one end and connected to the distribution chamber 12 at the other end, and the connecting points are connected through stainless steel hoses.

[0048] It can be further understood that the isolation member 10 is used to divide the interior of the second purge port body into a first chamber and a first chamber. The shape of the isolation member 10 is not specifically limited. For example, the shape of the isolation member 10 can be rectangular, arc-shaped, or fan-shaped. There is no specific limitation, but a rectangle is preferred. Of course, the above are just a few preferred shapes, which are set according to actual needs and are not limited here.

[0049] Furthermore, as a preferred embodiment of the present invention, one end of the third purge port 6 away from the distribution chamber 12 is detachably connected to the third air intake pipeline 4 , and the other end of the third air intake pipeline 4 is connected to the distribution chamber 12 .

[0050] In the embodiment of the present invention, the compressed gas supply to the third purging port 6 can be realized through the third air inlet pipeline 4, thereby realizing purging of the object to be cleaned.

[0051] It should be noted that the end of the third purge port 6 away from the distribution chamber 12 is detachably connected to the third air inlet pipeline 4, and the third purge port 6 can be disassembled and replaced as needed. For example, usually, the third purge port 6 is a disc-type upward jet nozzle, which is suitable for disc filters and inside-out filtering type filters, and can purge the object to be cleaned from the inside to the outside, so as to achieve purge of the object to be cleaned arranged on the mounting seat 7 in a direction perpendicular to the mounting seat 7. When purge the filter type filter from outside to inside, a column-type nozzle tooling can be added to the third purge port 6 or a column-type nozzle tooling can be directly installed to achieve the purpose of reverse purge, and then purge the object to be cleaned arranged on the mounting seat 7 in a direction parallel to the mounting seat 7.

[0052] Further, such as Figure 2 As shown, as a preferred embodiment of the present invention, a detachable filter screen 20 is provided at the connection between the recovery mechanism 18 and the shell 3.

[0053] In the embodiment of the present invention, by controlling the start and stop of the recovery mechanism 18, the oil-gas mixture generated during the purging process is filtered through the detachable filter screen 20 and then discharged from the recovery mechanism 18 to subsequent processing equipment.

[0054] In one example of the present invention, the recovery mechanism 18 includes an explosion-proof exhaust fan 19, an explosion-proof exhaust pipeline and a detachable filter 20, the detachable filter 20 can be a plug-in filter, the explosion-proof exhaust fan 19 is directly connected to the back of the shell 3, and the plug-in filter is arranged at the connection, the explosion-proof exhaust fan 19 is directly connected to the explosion-proof exhaust pipeline, and the explosion-proof exhaust fan is also connected to the automatic control unit signal in the electric control box 13, the automatic control unit can be a product in the prior art, such as a central processing unit and a programmable logic controller, and the specific model is selected according to the needs and is not limited here; The distribution chamber 12 can be controlled by the electric control box 13 to deliver compressed air. The distribution chamber 12 can also be an independent air compressor, which can blow compressed air to the driving blades 11 to drive the mounting seat 7 and the filter thereon to rotate (similar to the principle of windmill rotation). The distribution chamber 12 can also be controlled by the electric control box 13 to deliver compressed gas to the purge mechanism 1 to purge the object to be cleaned, thereby controlling the entire purge process. The explosion-proof exhaust fan 19 can also be controlled to start and stop by the electric control box 13. The oil-gas mixture generated during the purge process is filtered by the detachable filter 20 and then discharged to the subsequent processing equipment by the explosion-proof exhaust fan 19.

[0055] Furthermore, as a preferred embodiment of the present invention, a cover plate 23 for observing the interior of the shell 3 is also provided on the shell 3 .

[0056] In the embodiment of the present invention, the operating conditions inside the housing 3 can be observed through the cover plate 23, and the operation can be adjusted in time according to the actual flushing conditions.

[0057] In an example of the present invention, the cover plate 23 is hinged to the upper end of the housing 3 , so that the cover plate 23 can be opened or closed as needed.

[0058] In another example of the present invention, the cover plate 23 is a flip cover plate, and a transparent material observation hole is provided in the middle of the flip cover plate. It can be understood that the transparent material can be one of organic glass, quartz glass, polymethyl methacrylate, polystyrene, or polycarbonate, without specific limitation, but organic glass is preferred. Of course, the above are just a few preferred materials. The transparent material can also be polybisallyl diglycol carbonate, transparent glass fiber reinforced plastic, etc., which is set according to actual needs and is not limited here. Of course, in order to clearly and detailedly reflect this solution, the transparent material is mainly embodied in the form of organic glass in the following embodiments, but this is mainly to reflect the feasibility of the solution and is not limited.

[0059] like Figure 3As shown, as a preferred embodiment of the present invention, the distribution chamber 12 can be an air distribution bag in the prior art, and the side of the air distribution bag close to the shell 3 is respectively connected to the drive pipeline 8, the third air intake pipeline 4, the first air intake pipeline 15, the second air intake pipeline 16 and the manual pipeline 26, and the side of the air distribution bag away from the shell 3 is provided with an air intake manifold and an air outlet manifold for connecting with external air compression equipment to realize the input and output of compressed air, and the connection between the air intake manifold, the air intake and outlet manifolds and the air distribution bag is provided with a flow regulating component 24.

[0060] In an embodiment of the present invention, the distribution chamber 12, the air intake manifold, the manual pipeline 26, the drive pipeline 8, the third air intake pipeline 4, the first air intake pipeline 15, and the second air intake pipeline 16 together constitute a compressed air distribution system, wherein the distribution chamber 12 is respectively equipped with a flow regulating component 24 at the connection points with the manual pipeline 26, the drive pipeline 8, the third air intake pipeline 4, the first air intake pipeline 15, and the second air intake pipeline 16.

[0061] It should be noted that the flow regulating component 24 can be a valve product in the prior art, and the control of the valve can adopt a variety of transmission methods, such as manual, electric, hydraulic, pneumatic, turbine, electromagnetic, electromagnetic hydraulic, electro-hydraulic, gas-hydraulic, spur gear, bevel gear drive, etc. Preferably, the flow regulating component 24 is a combination of an electromagnetic flow valve and a manual ball valve in existing products. The specific model is selected according to demand and is not limited here. As long as it can act according to predetermined requirements under the action of pressure, temperature or other forms of sensor signals, or simply open or close without relying on sensor signals, the valve relies on a drive or automatic mechanism to make the opening and closing parts move up and down, slide, swing or rotate, thereby changing the size of its flow area to achieve its control function.

[0062] In one example of the present invention, the electromagnetic flow valve is signal-connected to the automation control unit of the electric control box 13, a pressure gauge 25 is installed on the manual pipeline 26, and the manual pipeline 26 is divided into two branches, each branch is equipped with a manual discharge valve 27, one branch is used for manual discharge, and the other branch is connected to a manual connecting pipe 28 for manual connection of a hose.

[0063] like Figure 4As shown, an embodiment of the present invention also provides an automatic filter cleaning device, including the above-mentioned blowing device, and the automatic filter cleaning also includes: an electrical control box 13, which is arranged at the upper end of the distribution chamber 12, and is used to control the distribution chamber 12 to deliver compressed gas to the blowing mechanism 1 to blow the object to be cleaned, and deliver compressed gas to the driving pipeline 8 to blow the rotating part 5 to drive the mounting seat 7 to rotate; the electrical control box 13 is also connected to the recovery mechanism 18 signal, and is used to drive the recovery mechanism 18 to extract impurities in the shell 3.

[0064] In the embodiment of the present invention, the operation of the distribution chamber 12 and the recovery mechanism 18 is controlled by the electric control box 13. The compressed gas is delivered to the driving pipeline 8 through the distribution chamber 12 to blow the rotating part 5 to drive the mounting seat 7 to rotate. At the same time, the compressed gas is delivered to the blowing mechanism 1 in cooperation with the distribution chamber 12 to blow the object to be cleaned. Compared with the traditional manual blowing, the blowing efficiency can be effectively improved, and 360-degree blowing without dead ends can be achieved. The impurities such as oil mist generated during cleaning are also recovered by the recovery mechanism 18, thereby avoiding the harm of oil mist inhalation to the operator.

[0065] Furthermore, as a preferred embodiment of the present invention, the automatic filter cleaning device also includes: casters 21, which are arranged at the lower end of the recovery mechanism 18, and are used to move the automatic filter cleaning device, and the lower end of the shell 3 is correspondingly provided with a plurality of adjustable legs 22 for cooperating with the casters 21.

[0066] In the embodiment of the present invention, the housing 3 is moved or fixed by two casters 21 and two adjustable legs 22 provided at the lower part of the housing 3. Of course, the casters 21 and the adjustable legs 22 can be existing products, and the specific number can also be selected according to needs, for example, four casters 21 and four adjustable legs 22 can be provided, or eight casters 21 and six adjustable legs 22 can be provided, which is not limited here.

[0067] In one embodiment of the present invention, a door body 30 is provided on the front of the shell 3, and the door body 30 is provided. The door body 30 can be a magnetic double-opening door, which can have a sealing effect. The lower part of the shell 3 is moved or fixed by two casters 21 and two adjustable legs 22.

[0068] In another example of the present invention, the electric control box 13 is installed on the angle iron by fixing bolts, the lower end of the angle iron is connected to the shell 3, and the distribution chamber 12 can be arranged in the space at the lower end of the angle iron, and the transition chamber 12 is installed and fixed by a U-shaped clamp.

[0069] In another embodiment of the present invention, taking the main engine fuel filter as an example, the manual cleaning time is about 30 minutes, while the equipment in the embodiment of the present invention only needs 2-3 minutes. The cleaning time of other types of filters is also shortened by about 80%, which greatly improves the efficiency. Moreover, there are dead angles and blind spots in manual cleaning, and the cleaning quality is not high. The equipment is a 360-degree cleaning without dead angles, which can thoroughly clean the residual liquid and pollutants on the filter and does not require high technical level of the operator. There is a risk of the operator being injured by compressed air during manual cleaning. The equipment can effectively avoid such injuries. At the same time, the oil-gas mixture is sucked away by the exhaust fan, which also avoids the harm of oil mist inhalation to the operator. The oil-gas mixture generated during the cleaning process gathers inside the equipment, and after the oil mist and oil droplets are collected by the filter, they are discharged to the atmosphere by the exhaust fan, which effectively solves the problem of oil and gas and pollutants running around during manual cleaning and polluting the entire cabin environment.

[0070] Figure 5 This is a working principle diagram of the automatic filter cleaning device provided by another embodiment of the present invention.

[0075] Further, the control of the explosion-proof exhaust fan 19 includes:

[0076] 1) In manual mode: the explosion-proof exhaust fan 19 continues to operate;

[0077] 2) In zero position mode: the explosion-proof exhaust fan 19 automatically stops running after 15 seconds of starting;

[0078] 3) In automatic mode: when the device has an operating signal, the explosion-proof exhaust fan 19 starts to run, and after the cleaning is completed, it stops after a delay of 10 seconds; control of the buzzer with light: after each cleaning is completed in the automatic state, an audible and visual prompt signal is issued until the reset button is pressed.

[0079] The above embodiment of the present invention provides a purging device, comprising a shell 3, a purging mechanism 1, a recovery mechanism 18 for extracting impurities in the shell 3, and a distribution chamber 12 for delivering compressed gas to the purging mechanism 1 to purge the object to be cleaned, the purging mechanism 1 comprises a mounting base 2, a mounting seat 7 is rotatably connected to the mounting base 2 via a rotating member 5, the distribution chamber 12 also delivers compressed gas to a driving pipeline 8 for blowing the rotating member 5 to drive the mounting seat 7 to rotate, and an automatic filter cleaning device is provided based on the purging device. The compressed gas is delivered to the driving pipeline 8 through the distribution chamber 12 to blow the rotating part 5 to drive the mounting seat 7 to rotate. At the same time, the compressed gas is delivered to the blowing mechanism 1 in cooperation with the distribution chamber 12 to blow the object to be cleaned. Compared with the traditional manual blowing, the blowing efficiency can be effectively improved, and 360-degree blowing without dead ends can be achieved. The oil mist and other impurities generated during cleaning are recovered through the recovery mechanism 18, thereby avoiding the harm of oil mist inhalation to the operator. This solves the problem that most of the existing filter blowing operations use manual blowing of filters, which has low working efficiency and easy pollution of the working environment.
