Description

Technical Field

[0001] This invention relates to the field of dust removal and gas-solid separation technology, and in particular to an automated rotary horizontal trapezoidal pleated dust collector filter cartridge assembly and its cleaning method. Background Technology

[0002] Current cartridge dust collectors commonly employ methods such as pulse jet cleaning, mechanical vibration, and scraper cleaning. However, when dealing with sticky or damp dust, these methods are often insufficient for thorough removal and require frequent operation, easily leading to filter material fatigue, high energy consumption, and secondary dust generation. Although ultrasonic vibration can be used directly for cartridge dust collection to improve the removal efficiency of sticky or damp dust, performing comprehensive ultrasonic vibration for each filter cartridge cleaning may result in high energy consumption and significant damage to the filter cartridge. Summary of the Invention

[0003] The present invention aims to provide an automated rotating horizontal trapezoidal pleated dust collector filter cartridge assembly and its cleaning method, so as to achieve zoned and efficient removal of sticky or wet dust accumulated on the filter cartridge, thereby reducing energy consumption and minimizing damage to the filter cartridge.

[0004] Therefore, the technical solution adopted by the present invention is as follows: an automated rotating horizontal trapezoidal pleated dust collector filter cartridge assembly, comprising a fixed protective shell with one end as an inlet and the other end as an outlet, an automatically rotating filter cartridge, a rotary bearing, an automatic dust removal hopper, and an annular adjustable fan blade assembly. The annular adjustable fan blade assembly and the filter cartridge are disposed within the fixed protective shell. The filter cartridge and the fixed protective shell are connected by a rotary bearing to achieve relative rotation. The automatic dust removal hopper is fixedly disposed at the bottom end of the fixed protective shell. The assembly also includes a zoned dust removal mechanism, which includes a control processing module, an ultrasonic generator, a first signal receiver, a second signal receiver, multiple photosensitive receivers, a light source, and a signal transmitter. A mounting bracket is fixedly disposed within the outlet end of the fixed protective shell. The left end of the mounting bracket extends into the filter cartridge and is fixedly connected to the light source. The photosensitive receiver is fixedly installed on the inner side wall of the fixed protective housing, and the ultrasonic generator is fixedly installed on the inner top wall of the fixed protective housing. Multiple photosensitive receivers and light sources are evenly spaced along the length of the filter cartridge. Multiple signal transmitters are fixedly installed on the filter cartridge and evenly spaced along the circumference of the filter cartridge to divide the filter cartridge into multiple filtration areas. The first signal receiver and the second signal receiver are fixedly installed on the inner side wall and inner top wall of the fixed protective housing, respectively, and correspond to the photosensitive receiver and the ultrasonic generator. The control processing module is electrically connected to the photosensitive receiver, the ultrasonic generator, the first signal receiver, the second signal receiver, and the automatic dust removal hopper.

[0005] As a preferred embodiment of the above scheme, a flow guide is fixedly installed on the left end of the filter cartridge.

[0006] A further preferred embodiment is that a protective net is fixedly installed at the inlet of the fixed protective shell.

[0007] A further preferred embodiment is that a secondary filter plate is fixedly installed between the filter cartridge outlet and the fixed protective housing outlet.

[0008] More preferably, an air curtain generator is fixedly installed at the outlet of the fixed protective housing.

[0009] More preferably, the filter cartridge is provided with multiple trapezoidal pleats.

[0010] A method for cleaning an automated rotating horizontal trapezoidal pleated dust collector filter cartridge assembly includes the following steps:

[0011] S1. The filter cartridge is divided into multiple filtering areas along the circumference by multiple signal transmitters, and the area between two adjacent signal transmitters is a filtering area.

[0012] S2. Control the light source to emit light that passes through the filtering area on the automatically rotating filter cartridge and is received by the photosensitive receiver. The photosensitive receiver transmits data to the control processing module. The two signal transmitters on both sides of the filtering area transmit position signals to the first signal receiver. The first signal receiver transmits positioning signals to the control processing module, thereby allowing the control processing module to determine the detected filtering area and judge the dust thickness of the filtering area.

[0013] S3. If the control processing module determines that the dust thickness in the filter area exceeds the set range and causes blockage, then the filter area is marked as a blocked area.

[0014] S4. The second signal receiver receives the position signals emitted by the two signal transmitters on both sides of the blockage area and transmits the positioning signal to the control processing module. The control processing module determines that the blockage area rotates to the position corresponding to the ultrasonic generator and controls the ultrasonic generator to generate vibration to loosen the dust in the blockage area.

[0015] S5. As the filter cartridge rotates downwards, the dust inside the clogged area falls into the automatic dust removal hopper.

[0016] S6. The control processing module controls the automatic dust removal hopper to discharge dust.

[0017] As a preferred embodiment of the above scheme, in step S4, the ultrasonic generator generates vibration using a pulsed or continuous method, and the ultrasonic excitation parameters are located between 20 kHz and 40 kHz, with a power density of 0.1 W / cm². 2 -5 W / cm 2 The width of a single pulse is 10 ms-200 ms.

[0018] More preferably, the control processing module marks filter areas that become clogged more than a set range as high-risk areas, and periodically controls the ultrasonic generator to vibrate and loosen dust in the high-risk areas to delay the clogging of the high-risk areas.

[0019] The beneficial effects of this invention are:

[0020] 1. The zoned dust removal mechanism can divide the surface of the automatically rotating filter cartridge into multiple filtration zones, and use ultrasonic vibration to remove sticky or damp dust in the filtration zones of the clogged filter cartridge. This forms a zoned and targeted high-efficiency peeling of accumulated sticky or damp dust, reducing energy consumption, minimizing damage to the filter cartridge, and increasing the service life of the filter cartridge.

[0021] 2. By using multiple photosensitive receivers and light sources, each filtration area of ​​the automatically rotating filter cartridge can be detected, so as to find the blocked filtration area in time.

[0022] 3. By employing a control processing module, a first signal receiver, a second signal receiver, and multiple signal transmitters, the system can automatically identify clogged filter areas as clogged areas and allow the ultrasonic generator to remove dust only from the identified clogged areas, thereby improving the accuracy of dust removal on the filter cartridge surface.

[0028] The present invention will now be further described with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-5As shown, an automated rotating horizontal trapezoidal pleated dust collector filter cartridge assembly includes a fixed protective shell 1 with one end as the inlet and the other end as the outlet, an automatically rotating filter cartridge 7, a rotary bearing 8, an automatic dust removal hopper 4, and an annular adjustable fan blade assembly 2. The annular adjustable fan blade assembly 2 and the filter cartridge 7 are disposed inside the fixed protective shell 1. The filter cartridge 7 and the fixed protective shell 1 are connected by the rotary bearing 8 to achieve relative rotation. The automatic dust removal hopper 4 is fixedly disposed at the bottom end inside the fixed protective shell 1.

[0030] The automated rotating horizontal trapezoidal pleated dust collector filter cartridge assembly also includes a zoned dust collection mechanism, which includes a control processing module, an ultrasonic generator 14, a first signal receiver 16, a second signal receiver 15, multiple photosensitive receivers 12, a light source 13, and a signal transmitter 6.

[0031] A mounting bracket 11 is fixedly installed inside the outlet end of the fixed protective housing 1. The left end of the mounting bracket 11 extends into the filter cartridge 7 and is fixedly connected to the light source 13. The photosensitive receiver 12 is fixedly installed on the inner side wall of the fixed protective housing 1. The ultrasonic generator 14 is fixedly installed on the inner top wall of the fixed protective housing 1. Multiple photosensitive receivers 12 and light sources 13 are evenly spaced along the length of the filter cartridge 7. Multiple signal transmitters 6 are fixedly installed on the filter cartridge 7 and are evenly spaced along the circumference of the filter cartridge 7 so as to divide the filter cartridge 7 into multiple filtration areas along the circumference. The first signal receiver 16 and the second signal receiver 15 are fixedly installed on the inner side wall and inner top wall of the fixed protective housing 1, respectively, and correspond to the photosensitive receiver 12 and the ultrasonic generator 14, respectively. The control processing module is electrically connected to the photosensitive receiver 12, the ultrasonic generator 14, the first signal receiver 16, the second signal receiver 15, and the automatic dust removal hopper 4.

[0032] During filtration, the annular adjustable fan blade assembly 2 is activated. The dust-laden airflow enters through the inlet of the fixed protective housing 1, passes through the annular adjustable fan blade assembly 2, reaches the vicinity of the automatically rotating filter cartridge 7, and then enters the interior of the filter cartridge 7. The dust is filtered out by the filter cartridge 7, becoming clean airflow. The clean airflow exits from the interior of the filter cartridge 7 through the outlet of the fixed protective housing 1. The airflow direction is as follows: Figure 2 As indicated by the arrow in the diagram. The automatic dust removal hopper 4 may be equipped with an anti-clogging device and a dust discharge sealing structure to reduce secondary dust. The fixed protective housing 1 may have an anti-static grounding and explosion-proof electrical and encapsulation design. The automatically rotating filter cartridge 7, the rotating bearing 8, the automatic dust removal hopper 4, and the annular adjustable fan blade assembly 2 are all existing technologies and will not be described in detail here.

[0033] A flow guide 5 is fixedly installed at the left end of the filter cartridge 7. A protective net 3 is fixedly installed at the inlet of the fixed protective shell 1. A secondary filter plate 9 is fixedly installed between the outlet of the filter cartridge 7 and the outlet of the fixed protective shell 1. An air curtain generator 10 is fixedly installed at the outlet of the fixed protective shell 1. Multiple trapezoidal pleats 17 are provided on the filter cartridge 7.

[0034] The airflow guide 5 is used to evenly distribute airflow and reduce dead zones. It can be a fixed guide vane structure made of wear-resistant material. The protective net 3 can prevent external debris from entering the fixed protective shell 1 and damaging the components. The secondary filter plate 9 can filter the clean airflow again, improving the cleanliness of the clean airflow. The air curtain generator 10 can be used to guide the filtered clean airflow to form a clean air curtain. The trapezoidal pleats 17 can increase the filtration area of ​​the filter cartridge 7 and improve the dust removal efficiency.

[0035] A method for cleaning an automated rotating horizontal trapezoidal pleated dust collector filter cartridge assembly includes the following steps:

[0036] S1. The filter cartridge 7 is divided into multiple filtering areas along the circumference by multiple signal transmitters 6, and the area between two adjacent signal transmitters 6 is a filtering area.

[0037] S2. Light emitted by the control light source 13 passes through the filtering area on the automatically rotating filter cartridge 7 and is received by the photosensitive receiver 12. The photosensitive receiver 12 transmits data to the control processing module. Position signals are transmitted to the first signal receiver 16 through the two signal transmitters 6 on both sides of the filtering area. The first signal receiver 16 transmits positioning signals to the control processing module, thereby allowing the control processing module to determine the detected filtering area and judge the dust thickness of the filtering area.

[0038] Both the light source 13 and the photosensitive receiver 12 can be fixedly mounted with transparent protective covers. These covers can be equipped with periodic cleaning mechanisms to reduce dust interference with the operation of the light source 13 and the photosensitive receiver 12. The signal transmitter 6 can be powered by a battery, which is fixedly mounted on the filter cartridge 7 to prevent the automatic rotation of the filter cartridge 7 from affecting the wiring of the signal transmitter 6.

[0039] S3. If the control processing module determines that the dust thickness in the filter area exceeds the set range and causes blockage, then the filter area is marked as a blocked area.

[0040] S4. The second signal receiver 15 receives the position signals emitted by the two signal transmitters 6 on both sides of the blockage area and transmits the positioning signal to the control processing module. The control processing module determines that the blockage area rotates to the position corresponding to the ultrasonic generator 14 and controls the ultrasonic generator 14 to generate vibration to loosen the dust in the blockage area.

[0041] In step S4, the ultrasonic generator 14 generates vibration using a pulsed or continuous method, with ultrasonic excitation parameters ranging from 20 kHz to 40 kHz and a power density of 0.1 W / cm². 2 -5 W / cm 2 The width of a single pulse is 10 ms-200 ms.

[0042] S5. As the filter cartridge 7 rotates downwards, the dust inside the clogged area falls into the automatic dust removal hopper 4.

[0043] S6, the control and processing module controls the automatic dust removal hopper 4 to discharge dust.

[0044] The operation control processing module marks the filter area that becomes clogged more than a set range as a high-risk area, and periodically controls the ultrasonic generator 14 to vibrate and loosen the dust in the high-risk area to delay the clogging of the high-risk area. The dust in the filter area can be sticky or moist dust.

[0045] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
