[0002] In industries such as coal, electricity, steel, and cement, a large amount of dust is generated during the production process, which harms the environment and workers' health.

[0003] Common dust collector filter materials include cloth bags, filter cartridges, plastic-sintered plates, etc. Large dust collectors require a large number of single filter materials to be used in combination. If some of the filter materials are blocked, the air volume will decrease. In severe cases, the air volume cannot cover the dust-producing area, and dust will overflow.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] At present, for large dust collectors that use a combination of single filter materials, when they need to be replaced and cleaned, and there are leaking or clogged filter materials, due to the lack of accurate and appropriate positioning means, they can only be checked one by one or dismantled as a whole for maintenance, thus wasting a lot of manpower and time. Based on this, the embodiment of the utility model provides a dust collector fault positioning device, which sets a number of filter components in the filter chamber of the dust collector. When the detection data of the concentration sensor and the pressure difference sensor changes, each valve is closed in turn to determine the leaking or clogged filter material. Remote alarm can be achieved, and the fault area can be accurately located, saving a lot of maintenance time and reducing production stoppage losses caused by maintenance.

[0030] In order to facilitate the understanding of this embodiment, a dust collector fault locating device according to an embodiment of the utility model is first introduced in detail.

[0031] Figure 1 A schematic diagram of the structure of a dust collector fault location device is provided for the implementation of the utility model. Figure 1 As shown, the device mainly includes: at least one group of filter components 610, a detection module 620 and a control module 630. The filter component 610 is arranged in the filter chamber of the dust collector. The detection module 620 includes a concentration sensor 400 and a pressure difference sensor 500. The concentration sensor 400 and the pressure difference sensor 500 are respectively arranged at the air outlet 300 of the dust collector. The control module 630 is electrically connected to the detection module 620 and the valve 110 respectively.

[0032] Among them, the filter assembly 610 includes a filter material 100, a valve 110 and a partition 120. The partition 120 is connected to the inner wall of the filter cavity to form a sub-air outlet. The valve 110 is located at the air outlet of the sub-air outlet. The filter material 100 is located in the filter cavity and below the sub-air outlet.

[0033] In the embodiment of the present application, the air outlet of the filter chamber of the dust collector can be divided into multiple sub-air outlets by a partition 120, a filter material 100 is arranged under each sub-air outlet, and a valve 110 is arranged at the sub-air outlet for opening or closing the connection between the sub-air outlet and the air outlet 300 of the dust collector. When the dust collector removes dust from the gas, the gas flows into the filter chamber of the dust collector through the air inlet 200 of the dust collector, and after filtering the gas with the filter material in the filter chamber, it flows into the air outlet of the dust collector through each sub-air outlet. When the dust collector is working, the data of the concentration sensor 400 set at the air outlet 300 of the dust collector can be obtained to determine whether the filter material 100 of the dust collector is leaking. When the data of the concentration sensor 400 is greater than the first standard value, the valves 110 in each sub-air outlet are controlled to be closed in turn, thereby determining the location of the leakage fault; by obtaining the data of the differential pressure sensor 500 set at the air outlet 300 of the dust collector, it is determined whether the filter material 100 of the dust collector is blocked. When the data of the differential pressure sensor 500 is less than the second standard value, the valves 110 in each sub-air outlet are controlled to be closed in turn, thereby determining the specific location of the blocked filter material 100. It can achieve accurate positioning of the fault area, save a lot of maintenance time, and reduce the loss of production stoppage caused by maintenance.

[0034] The above device is introduced in detail below.

[0035] In some embodiments, multiple filter assemblies 610 are evenly arranged along the dust entry direction of the filter chamber.

[0036] Specifically, according to actual needs, the air outlet of the dust collector can be divided into multiple sub-air outlets through the filter component 610, and two adjacent sub-air outlets are separated by a partition 120, and multiple partitions 120 are evenly arranged along the dust inlet direction of the filter chamber of the dust collector. By setting up multiple sub-air outlets, it is convenient to locate the fault position.

[0037] Furthermore, the partition 120 can be fixedly connected or detachably connected to the filter cavity of the dust collector, for example, the partition 120 can be connected to the inner wall of the filter cavity by welding, or a plurality of slots are provided on the inner wall of the filter cavity, and the partition 120 is inserted into the slots to achieve a detachable connection between the partition 120 and the inner wall of the filter cavity.

[0038] In some embodiments, the air outlet of the sub-air outlet is connected to the air outlet 300 of the dust collector.

[0039] Specifically, a valve 110 is provided at each sub-air outlet, and each sub-air outlet is respectively connected to the air outlet 300 of the dust collector to ensure that the filtered gas can be discharged smoothly, and the working condition of the filter material corresponding to each sub-air outlet can be detected by individually controlling the valve 110 in each sub-air outlet.

[0040] like Figure 2 As shown, in some embodiments, the control module 630 includes an acquisition unit 631, an analysis unit 632 and a control unit 633, wherein the acquisition unit 631 is respectively connected to the concentration sensor 400 and the pressure difference sensor 500, and is used to collect data from the concentration sensor 400 and the pressure difference sensor 500; the analysis unit 632 is connected to the acquisition unit 631, and is used to determine whether the filter material 100 has leakage and / or blockage based on the data from the concentration sensor 400 and the pressure difference sensor 500; the control unit 633 is respectively connected to the analysis unit 632 and the valve 110, and is used to control the valve 110 to open or close based on determining whether the filter material 100 has leakage and / or blockage.

[0041] Specifically, a particle concentration sensor 400 and a pressure difference sensor 500 are arranged at the air outlet 300 of the dust collector, the particle concentration sensor 400 is used to detect the particle concentration of the gas discharged after passing through the filter chamber, and the pressure difference sensor 500 is used to detect the pressure difference between the air inlet and the air outlet of the filter chamber, and the acquisition unit 631 is connected to the particle concentration sensor 400 and the pressure difference sensor 500 respectively, and is used to collect data of the particle concentration sensor 400 and the pressure difference sensor 500 in real time, and send the data of the particle concentration sensor 400 and the pressure difference sensor 500 to the analysis unit 632, and the analysis unit 631 is connected to the particle concentration sensor 400 and the pressure difference sensor 500 respectively, and sends the data of the particle concentration sensor 400 and the pressure difference sensor 500 to the analysis unit 632. When receiving the data of the particle concentration sensor 400 sent by the acquisition unit 631, the first control instruction is generated according to the first standard value, and the first control instruction is sent to the control unit 633, and the control unit 633 receives the control instruction sent by the analysis unit 632 and executes the first control instruction; and when receiving the data of the differential pressure sensor 500 sent by the acquisition unit 631, the analysis unit 632 generates a second control instruction according to the second standard value, and sends the second control instruction to the control unit 633, and the control unit 633 receives the control instruction sent by the analysis unit 632 and executes the second control instruction.

[0042] The step of generating a first control instruction according to the first standard value specifically includes:

[0043] The data of the particle concentration sensor 400 is compared with the first standard value, and whether the current dust collector meets the current working conditions is determined based on the comparison result. If the data of the particle concentration sensor 400 is greater than the first standard value, it is determined that the current dust collector has a leak, that is, the current dust collector has gas that has not been filtered through the filter material 100 directly entering the air outlet 300 of the dust collector, and a first control instruction is generated.

[0044] Furthermore, the first control instruction includes the order of closing the valve 110 in each sub-air outlet in turn, which can adopt the order of sorting the sub-air outlets, or customize the serial numbers of each sub-air outlet, and arrange the order of opening or closing the valve 110 according to the serial numbers, so as to facilitate finding the fault location quickly and accurately when a problem occurs.

[0045] For example, there are n sub-air outlets in the filter chamber of the current dust collector. If it is determined that there is a leak in the dust collector, the valve 110 in the n-1 sub-air outlet is closed, that is, the valve 110 of the first sub-air outlet is opened, and the valves 110 of the remaining sub-air outlets are closed. If at this time, the data of the particle concentration sensor 400 has not changed, the valve 110 of the second sub-air outlet is opened, and the valves 110 of the remaining sub-air outlets are closed. If at this time, the data of the particle concentration sensor 400 changes, that is, the data of the particle concentration sensor 400 is less than the first standard value or equal to the first standard value, it is determined that the leakage location is at the second sub-air outlet. If at this time, the data of the particle concentration sensor 400 has not changed, the valve 110 of the third sub-air outlet continues to be opened, and the valves 110 of the remaining sub-air outlets are closed until the location of the leak is determined.

[0046] The second control instruction is generated according to the second standard value, specifically including:

[0047] The data of the differential pressure sensor 500 is compared with the second standard value, and whether the current dust collector meets the current working conditions is determined based on the comparison result. If the data of the differential pressure sensor 500 is less than the first standard value, it is determined that the current dust collector is blocked, that is, part of the filter material 100 of the current dust collector is not working, and a second control instruction is generated.

[0048] Furthermore, the second control instruction includes the order of closing the valve 110 in each sub-air outlet in turn, which can adopt the order of sorting the sub-air outlets, or customize the serial numbers of each sub-air outlet, and arrange the order of opening or closing the valve 110 according to the serial numbers, so as to quickly and accurately find the fault location when a problem occurs.

[0049] For example, there are n sub-air outlets in the filter chamber of the current dust collector. If it is determined that there is a leak in the dust collector, the valve 110 in the n-1 sub-air outlet is closed, that is, the valve 110 of the first sub-air outlet is opened, and the valves 110 of the remaining sub-air outlets are closed. If at this time, the data of the pressure difference sensor 500 has not changed, the valve 110 of the second sub-air outlet is opened, and the valves 110 of the remaining sub-air outlets are closed. If at this time, the data of the pressure difference sensor 500 changes, that is, the data of the pressure difference sensor 500 is greater than the first standard value or equal to the second standard value, it is determined that the blockage position is at the position of the second sub-air outlet. If at this time, the data of the pressure difference sensor 500 has not changed, the valve 110 of the third sub-air outlet continues to be opened, and the valves 110 of the remaining sub-air outlets are closed until the blockage position is determined.

[0050] Furthermore, under normal operating conditions of the dust collector, if a certain sub-outlet is closed, the total filtration area of ​​the filter material 100 is reduced, so the data of the differential pressure sensor 500 is greater than the second standard value. Therefore, it is possible to determine whether the filter material 100 is blocked based on the data collected by the differential pressure sensor 500.

[0051] In some embodiments, the control module 630 further includes an alarm unit 634 , which is connected to the analysis unit 632 and is used to generate a fault alarm based on the determination that the filter material 100 is leaking and / or clogged.

[0052] Among them, the alarm unit 634 includes a voice subunit 6341 and a buzzer subunit 6342, and the voice subunit 6341 and the buzzer subunit 6342 are respectively connected to the analysis unit 632, the voice subunit 6341 is used for voice fault alarm, and the buzzer subunit 6342 is used for intermittent fault prompt alarm.

[0053] Specifically, when the fault location, i.e., the leakage location or the blockage location is determined, the analysis unit 632 sends the analysis result to the control module 630, and the control module 630 intermittently and cyclically broadcasts the location of the fault through the voice subunit 6341 according to the analysis result, such as leakage or blockage at the first sub-air outlet, and issues a fault prompt alarm through the buzzer subunit 6342, wherein the voice subunit 6341 and the buzzer subunit 6342 broadcast at intervals. This can remind the maintenance personnel that the dust collector needs to be repaired.

[0054] In some embodiments, the filter assembly 610 further includes an inspection port, which is located at one side of the filter cavity and communicates with the interior of the filter cavity.

[0055] A plurality of inspection ports can be provided, and one inspection port corresponds to one filter material. When a filter material fails, the failed filter material can be replaced through the inspection port, and the operation is simple and convenient.

[0056] In some embodiments, the filter assembly 610 further includes a monitoring unit, which is connected to the valves 110 respectively for monitoring the status of the valves 110 .

[0057] Specifically, after closing the valve 110 in any one of the sub-air outlets, the monitoring unit obtains the state of the valve 110 and determines whether the valve 110 is completely closed according to the current state of the valve 110 .

[0058] Furthermore, the monitoring unit may use a sensor to monitor the status of the valve 110 .

[0059] In some embodiments, the device further includes a storage module, which is connected to the detection module 620 and is used to store detection records. The detection records include the location and time of the fault, as well as the maintenance method, so that after the fault occurs again, the maintenance personnel can quickly check the detection records to understand the frequency, location and previous maintenance methods of the fault, which helps the maintenance personnel to more accurately determine the cause of the fault and may find more effective solutions, thereby shortening the maintenance time and improving the maintenance efficiency.

[0060] In some embodiments, the device further includes a display module 640 , which is connected to the control module and is used to display a curve of the change of data of the concentration sensor and / or the pressure difference sensor over time.

[0061] Specifically, the display module 640 is connected to the analysis unit in the control module, and the analysis unit obtains the change curve of the concentration sensor and / or the pressure difference sensor over time based on the received data, and sends the change curve to the display module. The time when the fault occurs can be clearly observed through the display module.
