Description

Technical Field

[0001] This utility model belongs to the field of limestone powder production, specifically, it relates to a limestone powder feeding anti-blocking and dust suppression device. Background Technology

[0002] Limestone is primarily formed in shallow marine environments. Based on its formation, limestone can be classified into clastic limestone (formed by water transport and sedimentation), biogenic limestone, and chemical and biochemical limestone. Based on its structure, it can be further subdivided into bamboo-leaf limestone, oolitic limestone, leopard-skin limestone, and nodular limestone, etc. However, during processing, the resulting powder can cause irreversible harm to the human body.

[0003] Chinese utility model patent CN219949871U discloses a limestone powder anti-clogging and dust suppression device, comprising a dust suppression body and a cross-shaped spray plate. Limestone powder is drawn into the chamber of the dust suppression body, and an air booster pump is fixed to the upper surface of the body. The air booster pump is connected to an exhaust ring plate via a booster pipe. While this device solves the problem of existing technologies requiring limestone powder to first fall into a sealed air chamber before spraying for dust suppression, which makes simultaneous limestone powder falling and dust suppression difficult, the limestone powder remains dispersed within the dust suppression body. This makes it difficult for the treatment liquid sprayed from the cross-shaped spray plate to fully mix with the limestone powder for effective dust suppression, thus affecting the dust suppression effect. Furthermore, since limestone powder contains metal dust, the device does not easily filter out these metal dust particles.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a limestone powder feeding anti-blocking and dust suppression device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A limestone powder feeding anti-clogging and dust suppression device includes: a feeding dust suppression box, an inlet pipe and an outlet pipe arranged on the upper and lower sides of the feeding dust suppression box, an air pump arranged on the outlet pipe, a plurality of atomizing nozzles arranged on the inner periphery of the feeding dust suppression box, a motor arranged on the upper side of the feeding dust suppression box, and a screen that is rotatably connected to the output end of the motor on the inner side of the feeding dust suppression box.

[0008] A magnetic suction rod is installed below the screen, and a stirring component is installed below the magnetic suction rod. The inner side of the material discharge dust suppression box is equipped with scraping components corresponding to the screen and the magnetic suction rod. Multiple fixed blades are fixedly connected to the inner periphery of the material discharge dust suppression box and above the screen.

[0009] Optionally, an annular channel is provided on the inner side of the material discharge dust suppression box, and the screen is located in the annular channel; an annular limiting groove is provided on the inner side of the annular channel, and multiple balls are movably fitted in the annular limiting groove, and the screen rotates in the annular channel through the multiple balls.

[0010] Optionally, the stirring component includes a connecting rod installed at the bottom of the magnetic rod and a plurality of stirring blades installed at the bottom of the connecting rod, wherein the plurality of stirring blades are arranged in a circumferential array at the bottom of the connecting rod; the stirring blades have an L-shaped structure.

[0011] Optionally, the scraping member includes a first scraper installed inside the material falling dust suppression box and abutting against the screen, and a second scraper installed below the first scraper and abutting against the outside of the magnetic suction rod.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] The magnetic suction rods installed inside the material discharge dust suppression box can adsorb metal dust particles in the limestone powder, thus facilitating the filtration and purification of these particles. The stirring element located below the magnetic suction rods, driven by a motor, increases the contact area between the atomizing nozzles' sprayed treatment liquid and the limestone powder. This allows the treatment liquid from multiple nozzles to effectively suppress dust, thereby improving the dust suppression effect. Furthermore, the scraping element inside the material discharge dust suppression box, while the motor drives the screen and magnetic suction rods to rotate, scrapes and cleans the dust adhering to their surfaces, further enhancing the treatment effect of the screen and magnetic suction rods on the limestone powder.

[0014] By using fixed blades installed inside the dust suppression box, the limestone powder that has clumped inside the dust suppression box can be dispersed. With the suction of the air pump, the dispersed limestone powder is discharged through the screen and discharged through the discharge pipe, which prevents the limestone powder from overflowing back into the feeder and thus reduces the clogging of limestone powder during the discharge process.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Please see Figure 1-5 As shown, this embodiment provides a limestone powder feeding anti-clogging and dust suppression device, including: a feeding dust suppression box 1, a feeding pipe 3 and a discharging pipe 2 are provided on the upper and lower sides of the feeding dust suppression box 1, an air pump 5 is provided on the discharging pipe 2, a plurality of atomizing nozzles 8 are provided on the inner periphery of the feeding dust suppression box 1, a motor 4 is provided on the upper side of the feeding dust suppression box 1, and a screen 7 is rotatably connected to the output end of the motor 4 on the inner side of the feeding dust suppression box 1.

[0028] A magnetic suction rod 9 is installed below the screen 7, and a stirring component 10 is installed below the magnetic suction rod 9. A scraping component 11 corresponding to the screen 7 and the magnetic suction rod 9 is installed inside the material discharge dust suppression box 1. Multiple fixed blades 14 are fixedly connected to the inner circumference of the material discharge dust suppression box 1 and above the screen 7.

[0029] The magnetic suction rod 9 installed inside the material discharge dust suppression box 1 can adsorb metal dust particles in limestone powder, thus facilitating the filtration and purification of metal dust particles in limestone powder. The stirring element 10 installed below the magnetic suction rod 9, driven by the motor 4 through the magnetic suction rod 9, increases the contact area between the treatment liquid sprayed by the atomizing nozzle 8 and the limestone powder, enabling the treatment liquid sprayed by multiple atomizing nozzles 8 to fully suppress dust in the limestone powder, thereby improving the dust suppression effect. The scraper 11 installed inside the material discharge dust suppression box 1, while the motor 4 drives the screen 7 and the magnetic suction rod 9 to rotate, scrapes and cleans the dust adhering to the surface of the rotating screen 7 and the magnetic suction rod 9, thereby improving the treatment effect of the screen 7 and the magnetic suction rod 9 on the limestone powder.

[0030] By using fixed blades 14 installed inside the dust suppression box 1, the limestone powder that has clumped inside the dust suppression box 1 can be dispersed. With the suction of the air pump 5, the dispersed limestone powder is discharged through the screen 7 and discharged through the discharge pipe 2, which avoids the limestone powder overflowing back into the feeder and thus reduces the clogging of limestone powder during the discharge process.

[0031] like Figure 4-5 As shown, in this embodiment, an annular channel 6 is provided on the inner side of the material falling dust suppression box 1, and the screen 7 is located in the annular channel 6; an annular limiting groove 12 is provided on the inner side of the annular channel 6, and multiple balls 13 are movably fitted in the annular limiting groove 12, and the screen 7 rotates in the annular channel 6 through the multiple balls 13.

[0032] like Figure 4 As shown, the stirring component 10 in this embodiment includes a connecting rod 1001 installed at the bottom of the magnetic rod 9 and a plurality of stirring blades 1002 installed at the bottom of the connecting rod 1001. The plurality of stirring blades 1002 are arranged in a circumferential array at the bottom of the connecting rod 1001; the stirring blades 1002 have an L-shaped structure.

[0033] When limestone powder needs to be fed to suppress dust, the air pump 5 starts, drawing the limestone powder from the feed pipe 3 into the dust suppression box 1. The motor 4 starts, driving the screen 7 and magnetic rod 9 to rotate. The magnetic rod 9 adsorbs the metal dust particles in the limestone powder. Multiple atomizing nozzles 8 spray the treatment agent to suppress the dust in the limestone powder. The limestone powder is further filtered through the screen 7 and discharged through the discharge pipe 2. While the motor 4 drives the screen 7 and magnetic rod 9 to rotate, it also drives multiple L-shaped stirring blades 1002 to rotate through the connecting rod 1001, increasing the contact area between the treatment liquid and the limestone powder. This allows the treatment liquid sprayed from the multiple atomizing nozzles 8 to fully suppress the dust in the limestone powder, thereby improving the dust suppression effect.

[0034] like Figure 4As shown, the scraper 11 in this embodiment includes a first scraper 1101 installed inside the material falling dust suppression box 1 and abutting against the screen 7, and a second scraper 1102 installed below the first scraper 1101 and abutting against the outside of the magnetic rod 9.

[0035] When the motor 4 starts and drives the screen 7 and magnetic rod 9 to rotate, the first scraper 1101 scrapes and cleans the limestone powder adhering to the bottom of the rotating screen 7, and the second scraper 1102 scrapes and cleans the metal dust adsorbed on the surface of the rotating magnetic rod 9, thereby improving the processing effect of the screen 7 and magnetic rod 9 on limestone powder.

Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model.
