DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0027] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" 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 a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Referring to the accompanying drawings, an open dry dust removal device is described, including a box body 1, an air outlet 11, a plurality of filter cartridges 5 and an air duct bottom plate 6, the box body 1 includes an air inlet door 2 and a plurality of filter cartridge doors 3, both of which are hollow structures, the air inlet door 2 is rotatably connected to the short side of the box body 1, and the plurality of filter cartridge doors 3 are rotatably connected to the long side of both sides of the box body 1, the air outlet 11 is fixedly connected to the side of the box body 1 away from the air outlet door 2, the filter cartridge 5 includes a filter cartridge core and a bag filter The filter cartridge core is formed by an inclined arrangement of deep pleat structures, and the bag filter layer is wrapped around the outside of the filter cartridge core. Multiple filter cartridges 5 are evenly distributed inside the box 1. The air duct bottom plate 6 is provided with an air duct bottom plate through hole 14 with the same diameter as the filter cartridge 5. The top of the filter cartridge 5 is connected to the air duct bottom plate through hole 14. The air duct bottom plate 6 is fixedly connected to the inside of the box 1 above the air outlet door 2. The air duct bottom plate 6, the top surface of the box 1, and the side surface of the box 1 above the air outlet door 2 constitute an air duct 15, which is connected to the outside of the box through the air outlet 11. Specifically, the size of the box 1 is 5m×1.5m×1.5m, and the interval between adjacent deep pleats is 5-20mm.

[0029] The present invention increases the air inlet area and improves the dust removal efficiency by adding an air inlet door 2 and a plurality of filter cartridge doors 3 to the structure of the box body 1, which can also reduce the wind speed of the dust-laden airflow when entering the filter cartridge 5, thereby improving the dust removal effect. The dust accumulation condition of the filter cartridge 5 can also be intuitively observed, which is convenient for regular cleaning and replacement of the filter cartridge 5. The present invention can increase the filtration area of ​​the filter material through the inclined arrangement of the deep pleated structure of the filter cartridge 5, and can also reduce the wind speed flowing through the surface of the deep pleated structure to improve the filtration effect. At the same time, the difficulty of self-cleaning of the filter cartridge 5 is reduced by expanding the gap between adjacent deep pleats to 5-20mm, and the aging and rupture of the filter cartridge 5 caused by high temperature or chemical media in the mine environment is further reduced by adding a bag filter layer, thereby increasing the service life of the filter cartridge 5, reducing the maintenance cost of the device, and improving the stability of the dust removal device.

[0030] The bottom end of the filter cartridge 5 is sealed, and the cross-section of the top end of the filter cartridge 5 is circular. The top end of the filter cartridge 5 is connected to the air duct bottom plate 6. The deep pleat structure of the filter cartridge 5 is arranged obliquely, which will cause a gap between the filter cartridge 5 and the air duct bottom plate, and then the dust-laden airflow flows into the air duct through the gap. In order to avoid the above phenomenon, the top end of the filter cartridge 5 is set to be circular, which is convenient for fitting with the side of the air duct bottom plate 6. The bottom end seal and the circular shape are both to ensure the closedness of the open dry dust removal device, and will not cause the dust-laden airflow to escape into the air duct 15, thereby improving the reliability of the dust removal device.

[0031] A plurality of filter cartridge support frames 8 are evenly arranged at the bottom of the housing 1, and the filter cartridge 5 is connected to the housing 1 through the filter cartridge support frames 8. Specifically, the filter cartridge support frames 8 are multiple columnar structures with even gaps connected to the long strip bottom plate, and each filter cartridge support frame 8 can fix multiple filter cartridges 5. Multiple filter cartridge support frames 8 are parallel and evenly distributed along the short side of the housing 1. Through the arrangement of the filter cartridge support frames 8, the arrangement of the filter cartridges 5 is parallel and evenly distributed with the short side of the housing 1, so that the dust removal of the dust-laden airflow is evenly distributed to each filter cartridge, ensuring that the dust removal amount of each filter cartridge is within an average range. The filter cartridge support frame 8 is fixedly connected to the bottom of the housing 1, and the bottom of the filter cartridge 5 is sleeved on the filter cartridge support frame 8. The filter cartridge support frame 8 has a simple structure and does not occupy too much space at the bottom of the housing 1. The installation method of the filter cartridge 5 sleeved on the filter cartridge support frame 8 is also convenient for manual replacement of the filter cartridge 5, saving replacement time and simplifying the operation process.

[0032] The diameter of the air outlet 11 is greater than the height of the air duct 15. The diameter of the air outlet 11 is greater than the height of the air duct 15, which can reduce the velocity of the filtered air flow, thereby preventing the mine dust from being blown up again and forming secondary pollution.

[0033] The air inlet door 2 and the filter cartridge door 3 are both manually locked and opened by the lock buckle 7. Specifically, when the open-type dry dust removal device is removing dust, the lock buckle 7 is locked, and the dust-laden airflow enters the box body 1 only through the open hole 4. When the filter cartridge 5 of the open-type dry dust removal device is seriously dusted and cannot be completely self-cleaned by the vibrating dust removal device 12, the air inlet door 2 and the filter cartridge door 3 are opened by the lock buckle 7 to manually clean the dust or replace the filter cartridge 5, thereby ensuring the normal dust removal function of the filter cartridge 5 and the stability of the dust removal of the device.

[0034] The bottom of the filter cartridge 5 is fixedly connected to the vibrating dust removal device 12 through a transmission plate 16 for self-cleaning. Specifically, the vibrating dust removal device 12 is a prior art and will not be described in detail here. The vibrating dust removal device 16 is connected to each filter cartridge 5 through a transmission plate. When a self-cleaning instruction is received, the vibrating dust removal device 12 transmits vibration to each filter cartridge 5 through the transmission plate 16. The self-cleaning function of the filter cartridge 5 can reduce the blockage of the filter cartridge 5 due to dust accumulation, thereby improving the dust removal efficiency. The open dry dust removal device is cleaned by self-cleaning dust removal and manual dust removal, which can greatly extend the service life of the filter cartridge 5 and improve the dust removal efficiency.

[0035] A plurality of dust collection chambers 9 are evenly distributed at the bottom of the box body 1, and a handle 4 is fixed to the surface of each dust collection chamber 9. Preferably, the dust collection chamber 9 is a drawer structure, and each dust collection chamber 9 can be pulled out of the box body 1 in one direction through the handle 4. Each dust collection chamber 9 is arranged between two adjacent filter cartridge support frames 8, so that the accumulated dust filtered out by each filter cartridge 5 can be collected to the greatest extent. When the dust in the dust collection chamber 9 accumulates to a certain extent, the dust collection chamber is manually pulled out from the bottom of the box body 1 through the handle 17 and cleaned.

[0036] The dust collecting chamber 9 is fixedly connected to the bottom of the box body 1 by an anti-drop pin 10. The dust collecting chamber 9 is fixed by the anti-drop pin 10 to prevent the dust collecting chamber from being blown out due to wind force during the dust removal process, thereby improving the stability of the device.

[0037] A plurality of dust sensors 13 are arranged on the air duct 15, and the self-cleaning instruction is transmitted to the vibration dust removal device 12 through the dust sensors 13. The air filtered by the open dry dust removal device is blown out through the air outlet 11. The dust sensor 13 can detect the air blown out of the air outlet 11 in real time. When the filtered air contains dust, the dust sensor 13 transmits the self-cleaning instruction to the vibration dust removal device 12, and the vibration dust removal device 12 starts to self-clean the filter cartridge 5. The signal linkage between the dust sensor 13 and the vibration dust removal device 12 further improves the reliability of the device.

[0038] The specific working process of an open dry dust removal device described in the present invention is as follows:

[0039] The open dry dust removal device is moved to the area to be dusted, and the dust-laden airflow enters the interior of the box body 1 through the filter cartridge door 3 and the air outlet door 2, and the dust-laden airflow is filtered and dust-removed by the filter cartridge 5. The filtered clean airflow enters the air duct 15 and is blown out from the air outlet pipe 11 after the dust concentration is detected by the dust sensor 13 to be qualified, and the filtered dust is adsorbed on the filter cartridge 5. When the dust sensor 13 detects that the dust concentration is unqualified, the dust sensor 13 transmits the self-cleaning instruction to the vibrating dust removal device 12, and the vibrating dust removal device 12 transmits the vibration to the filter cartridge 5 through the transmission plate 16, so as to realize the self-cleaning of the filter cartridge 5. Through the self-cleaning and manual cleaning of the filter cartridge 5, the dust adsorbed on the filter cartridge 5 falls into the dust collecting chamber 9. When the dust in the dust collecting chamber 9 accumulates to a certain extent, the anti-drop pin 10 is manually opened and the handle is pulled to pull the dust collecting chamber 9 out of the box for cleaning.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
