Description

Technical Field

[0001] This invention relates to the field of dust removal, and more particularly to a pulse dust collector for the production of heavy calcium carbonate powder. Background Technology

[0002] Dust control is an extremely important aspect of the production process of heavy calcium carbonate powder. The production process typically involves multiple steps, including raw material crushing, grinding, and grading, all of which generate significant amounts of dust. If left uncontrolled, this dust can damage production equipment and severely impact the working environment and employee health. Therefore, using efficient dust collection equipment is essential.

[0003] Traditional dust removal methods, such as cyclone dust collectors or wet scrubbers, often suffer from low dust removal efficiency and high maintenance costs. Therefore, we need a pulse jet dust collector that can reduce maintenance workload while maintaining high efficiency through continuous pulse cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide a pulse dust collector for the production of heavy calcium carbonate powder, so as to improve the problem of poor dust removal effect in the prior art.

[0005] A pulse dust collector for heavy calcium carbonate powder production includes an outer frame, a dust hopper installed on the lower side of the outer frame, a filter bag installed on the upper side of the outer frame, an air pipe connected to the upper inner side of the outer frame, an air outlet corresponding to the filter bag provided on the air pipe, the air outlet being located above the filter bag, an air bag installed on the side wall of the outer frame, a pulse valve installed on the air pipe and connected to the air bag, and an air inlet connected to the lower side of the outer frame.

[0006] More preferably, a baffle is rotatably connected to the lower side of the outer frame, the baffle is located above the air inlet, and the baffle is used to block the gas entering through the air inlet.

[0007] More preferably, a winding drum is installed on the lower inner side of the outer frame, the winding drum is located on the upper side of the baffle, and a first electric slide rail is installed on the lower inner side of the outer frame. A filter screen is connected to the slider of the first electric slide rail, and the filter screen is rotatably connected to the winding drum. The winding drum is used to store the filter screen.

[0008] More preferably, a spring is connected between the winding drum and the filter screen.

[0009] More preferably, a photosensor is provided at the bottom of the filter bag, and the photosensor is electrically connected to the first electric slide rail.

[0010] More preferably, a second electric slide rail is provided on the upper side of the outer frame. The second electric slide rail is electrically connected to the photosensor, and a scraper is connected to the slider of the second electric slide rail.

[0011] More preferably, the scraper has evenly distributed circular holes, and the scraper is used to scrape off the dust on the filter bag.

[0012] More preferably, a pull rope is connected between the filter screen and the baffle, and the pull rope is used to drive the baffle to rotate and open.

[0013] More preferably, a torsion spring is connected between the baffle and the outer frame.

[0014] More preferably, the pulse valve is electrically connected to the photosensor.

[0015] Compared with the prior art, the present invention has the following advantages: The pulse valve of the present invention performs jet cleaning of the filter bag to ensure its working efficiency; the baffle initially blocks the gas entering through the inlet, causing some dust to settle; the filter screen provides initial dust removal before the gas contacts the filter bag, reducing the workload on the filter bag; the scraper removes dust from the filter bag; and the photosensitive sensor, in conjunction with the first and second electric slide rails and the pulse valve, activates the pulse valve to remove dust from the filter bag when internal dust removal is required within the outer frame. Retracting the filter screen serves two purposes: firstly, it allows for the shaking off of dust from the screen through rewinding and movement; secondly, it prevents dust from the upper filter bag from falling onto the screen. After the filter screen is retracted, the scraper plate moves to remove dust from the filter bag, reducing the burden on the pulse valve. Finally, the pulse valve performs a thorough and precise dust removal on the filter bag. The filter screen is equipped with a pull rope and a torsion spring. When the filter screen is retracted, the pull rope is released, causing the torsion spring to reset and rotate the baffle to its original position. This baffle blocks the air inlet, preventing continuous gas from entering the frame during dust removal and affecting the dust removal effect. Attached Figure Description

Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components.

[0023] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0024] Example 1: This embodiment of the invention provides a pulse dust collector for the production of heavy calcium carbonate powder, such as... Figure 1 and Figure 2 As shown, the device includes an outer frame 1, with a dust hopper 2 installed on the lower side of the outer frame 1. The dust hopper 2 has a discharge port at its bottom, which is closed by a hinged plate for dust discharge. A filter bag 3 is installed on the upper side of the outer frame 1, with a photosensitive sensor 14 at its bottom. An air pipe 4 is connected to the upper inner side of the outer frame 1, with an air outlet 5 corresponding to the filter bag 3 located on the upper side of the filter bag 3. An air bag 6 is installed on the side wall of the outer frame 1, and a pulse valve 7 is installed on the air pipe 4. The pulse valve 7 is electrically connected to the photosensitive sensor 14 and is connected to the air bag 6. An air inlet 8 is connected to the lower side of the outer frame 1, and a baffle 9 is rotatably connected to the lower inner side of the outer frame 1. The baffle 9 is located above the air inlet 8 and is used to block the gas entering through the air inlet 8.

[0025] During the production of heavy calcium carbonate powder, the gas enters the outer frame 1 through the air inlet 8. The dust in the gas is first blocked by the baffle 9. After some of the dust is blocked, it settles and falls into the dust hopper 2. The rest of the gas continues to rise and is filtered by the filter bag 3. The clean gas is discharged from the upper air outlet 5. When the photosensitive sensor 14 detects that the dust on the filter bag 3 has accumulated to a certain extent, it controls the pulse valve 7 to start. The pulse valve 7 outputs the gas in the air bag 6 through the air pipe 4 to the air outlet 5 to perform pulse dust removal on the filter bag 3 so that the filter bag 3 can be recycled.

[0026] Example 2: Based on Example 1, as follows Figures 2-4 As shown, a winding drum 10 is installed on the lower inner side of the outer frame 1. The winding drum 10 is located on the upper side of the baffle 9. A first electric slide rail 11 is installed on the lower inner side of the outer frame 1. A filter screen 12 is connected to the slider of the first electric slide rail 11. The left side of the filter screen 12 is rotatably connected to the winding drum 10. The winding drum 10 is used to store the filter screen 12. A spring 13 is connected between the winding drum 10 and the filter screen 12. The photosensor 14 is electrically connected to the first electric slide rail 11.

[0027] To ensure the dust removal effect of the filter bag 3, an additional filter screen 12 is set in the outer frame 1 to perform preliminary dust removal on the gas. To prevent dust on the filter bag 3 from falling onto the filter screen 12 during pulse dust removal, when the photosensitive sensor 14 detects that the dust on the filter bag 3 has accumulated to a certain extent, it will first control the first electric slide rail 11 to start, so that the filter screen 12 moves to the left, the spring 13 resets, and drives the filter screen 12 to be stored in the winding drum 10.

[0028] Example 3: Based on Example 2, such as Figure 2 and Figure 5 As shown, a second electric slide rail 15 is provided on the upper side of the outer frame 1. The second electric slide rail 15 is electrically connected to the photosensitive sensor 14. A scraper 16 is connected to the slider of the second electric slide rail 15. The scraper 16 has evenly distributed round holes and is used to scrape off the dust on the filter bag 3.

[0029] When the filter screen 12 is stored in the winding drum 10, the photosensor 14 controls the second electric slide rail 15 to start, so that the second electric slide rail 15 drives the scraper 16 to scrape the dust on the filter bag 3 downwards, thereby improving the dust removal effect of the pulse valve 7. Thus, the photosensor 14 first controls the first electric slide rail 11 to start, storing the filter screen 12, then controls the second electric slide rail 15 to start, so that the scraper 16 scrapes the dust on the filter bag 3, and finally, the photosensor 14 controls the pulse valve 7 to start, performing pulse jet dust removal on the filter bag 3.

[0030] Example 4: Based on Example 3, such as Figure 3 As shown, a pull rope 17 is connected between the filter screen 12 and the baffle 9. The pull rope 17 is used to drive the baffle 9 to rotate and open. A torsion spring 18 is connected between the baffle 9 and the outer frame 1.

[0031] During the dust removal process inside the outer frame 1, in order to prevent gas from continuously entering and affecting the dust removal effect, when the filter screen 12 is stored, the filter screen 12 releases the pull rope 17, so that the torsion spring 18 resets and drives the baffle 9 to rotate and reset, so that the baffle 9 blocks the air inlet 8.

[0032] While embodiments of the present invention have been described in detail above, it will be apparent to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations fall within the scope and spirit of the invention as set forth in the claims. Furthermore, the invention described herein may have other embodiments and can be implemented or carried out in various ways.
