Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0032] See attached Figures 1 to 2 , gives a schematic embodiment of the pressure-measurable and controllable dust removal device proposed in the present invention, which consists of a dust collector 1, a first pressure gauge 2 and a first controller 3.

[0033] The dust collector 1 has a first chamber 11 and a second chamber 12 that are connected. The first chamber 11 has an air inlet, and the second chamber 12 has an air outlet. A dust bag is installed in the first chamber 11. Air enters the dust collector through the air inlet of the first chamber 11, is filtered and collected by the dust bag, and then enters the second chamber 12. Finally, it is discharged through the air outlet of the second chamber 12. The discharged air is clean and dust-free.

[0034] In this embodiment, the dust collector 1 further includes a fan 9, which is provided at the air outlet of the second chamber 12 and is connected to the first controller 3. The provision of the fan 9 can increase the rate at which air is discharged from the second chamber 12, thereby improving the working efficiency of the dust collector 1.

[0035] The first pressure gauge 2 and the first controller 3 are installed on the outer wall of the dust collector 1. The first pressure gauge 2 is connected to the first chamber 11 and the second chamber 12 through a PU tube to monitor the pressure difference between the first chamber 11 and the second chamber 12. A first pressure threshold range is preset in the first controller 3. The first controller 3 is electrically connected to the first pressure gauge 2 to obtain the pressure difference between the first chamber 11 and the second chamber 12. The first controller 3 is electrically connected to the dust collector 1 to control the dust collector 1 to stop running when the pressure difference between the first chamber 11 and the second chamber 12 exceeds the first pressure threshold range. The dust collector 1 can automatically stop running when the pressure difference between the first chamber 11 and the second chamber 12 is too large, and has high safety and stability. After the dust collector 1 stops running, it can be restarted and used after inspection and maintenance by the staff.

[0036] In order to improve safety, the pressure-measurable dust removal device also includes a pneumatic connector. One end of the PU tube is connected to the first pressure gauge 2 through the pneumatic connector, and the other end of the PU tube is connected to the first chamber 11 and the second chamber 12 through the pneumatic connector.

[0037] To facilitate cleaning of the dust bags and prevent the pressure difference between the first chamber 11 and the second chamber 12 from exceeding a predetermined pressure threshold due to bag clogging, the dust collector 1 in this embodiment further includes a pulse backflush device 13, which is positioned above the dust bags and sprays air into the bags. The dust collector 1 also includes an air source 14, which is connected to the pulse backflush device 13 to provide compressed air. The pulse backflush device 13 removes dust adhering to the dust bags by spraying compressed air.

[0038] In order to open or close the pulse back-blow device 13, in this embodiment, the pulse back-blow device 13 includes a pulse control valve 131, which is used to open or close the pulse back-blow device 13. Specifically, a plurality of pulse control valves 131 are provided according to the size of the dust collector 1 to realize the rotation cleaning of the dust bags and improve the cleaning effect and efficiency. The pulse control valve 131 is electrically connected to the first controller 3, so that the first controller 3 controls the opening of one or a group of pulse control valves 131 to perform dust removal work, and after a set time, controls the opening of the next or next group of pulse control valves 131 to perform dust removal work. The rotation cleaning method can ensure a good cleaning effect, improve the efficiency and performance of the dust collector 1, and can also avoid excessive wear of certain parts of the dust bags, extend the service life of the dust bags, and improve the durability and reliability of the dust collector 1.

[0039] In order to ensure the purging effect of the pulse back-blowing device 13, it is also necessary to ensure that the pressure of the air source 14 is sufficient. To this end, in this embodiment, the dust removal device with pressure measurable control also includes a second pressure gauge 4 and a second controller 5. The second pressure gauge 4 and the second controller 5 are installed on the outer wall of the dust collector 1. The second pressure gauge 4 is connected to the air source 14 through a PU tube to monitor the pressure of the air source 14. A second pressure threshold range is preset in the second controller 5. The second controller 5 is electrically connected to the second pressure gauge 4 to obtain the pressure of the air source 14. The second controller 5 is electrically connected to the dust collector 1 to control the dust collector 1 to stop running when the pressure of the air source 14 exceeds the second pressure threshold range. This can prevent the dust bag from running in a low-pressure state for a long time, prevent the dust bag from being blocked or even exploding, and reduce safety risks. The dust collector 1 stops running and can be restarted after inspection and maintenance by the staff.

[0040] In order to improve safety, one end of the PU tube is connected to the second pressure gauge 4 through a pneumatic connector, and the other end of the PU tube is connected to the air source 14 through a pneumatic connector.

[0041] When the pressure difference between the first chamber 11 and the second chamber 12 begins to become abnormal but does not exceed the first pressure threshold range, effective measures are taken in advance to restore the pressure difference between the first chamber 11 and the second chamber 12 to normal, which can improve the stability of the dust collector 1 and avoid the negative effects caused by the shutdown of the dust collector 1. In this embodiment, the first controller 3 is also preset with a third pressure threshold range, which is smaller than the first pressure threshold range. The pressure-measurable dust removal device also includes a regulator 6, which is connected to the first controller 3 and the pulse control valve 131 respectively to increase the opening frequency of the pulse control valve 131 when the pressure difference between the first chamber 11 and the second chamber 12 exceeds the third pressure threshold range. The higher the opening frequency of the pulse control valve 131, the faster the compressed air injection to remove the dust attached to the dust bag, blow away the blockage in the dust bag, and restore the pressure difference between the first chamber 11 and the second chamber 12 to normal.

[0042] When the first controller 3 or the second controller 5 controls the dust collector 1 to stop running, in order to enable the staff to discover it in time, in this embodiment, the pressure-measurable dust removal device also includes a first sound and light alarm 8 and a second sound and light alarm 7. Among them, the first sound and light alarm 8 is connected to the first controller 3 to sound and light alarm when the pressure difference between the first chamber 11 and the second chamber 12 exceeds the first pressure threshold range. The second sound and light alarm 7 is connected to the second controller 5 to sound and light alarm when the pressure of the gas source 14 exceeds the second pressure threshold range. After the staff sees or hears the sound and light alarm, they will promptly inspect or maintain the dust collector 1 so that the dust collector 1 can resume normal use as soon as possible. The staff can easily monitor the working status of the dust collector 1, with less manual operation, which can reduce the occurrence of operational safety accidents and improve the work experience of the staff.

[0043] In the above-mentioned schematic embodiment, the pressure-measurable dust removal device consists of a dust collector, a first pressure gauge and a first controller. It can effectively monitor the operating status of the dust collector in real time, detect abnormalities in time and perform maintenance. It has high safety, high degree of automation, high work efficiency, low maintenance cost, and has broad application prospects and economic benefits.

[0044] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0045] The above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention. They should all be included in the scope of the technical solution for which protection is requested in the present invention.
