DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0034] The present application provides a gas-solid coupling dust suppression material guiding groove, which comprises a support column 1;

[0035] The inner end of the support column 1 is provided with a material guiding mechanism 2 for coal spillage, one end of the top of the material guiding mechanism 2 is provided with a filter blocking mechanism 3 for preventing dust leakage, and the other end of the top of the material guiding mechanism 2 is provided with an atomization mechanism 4 for dust suppression;

[0036] The filter blocking mechanism 3 comprises a driving assembly, a transmission assembly, an extension assembly, a shielding assembly and a sliding assembly. The driving assembly is arranged at one end of the top of the material guiding mechanism 2. The bottom of the driving assembly is provided with the transmission assembly. One side of the transmission assembly is provided with the extension assembly. One side of the extension assembly is provided with the sliding assembly. The bottom of the extension assembly is provided with the shielding assembly.

[0037] Through the cooperation between the driving assembly, the transmission assembly, the extension assembly, the shielding assembly and the sliding assembly, the coal material in the material guiding groove can be prevented and blocked from dust, and the opening degree of the curtain can be changed in an extendable and adjustable manner, so as to adapt to the coal material conveying.

[0038] The atomization mechanism 4 comprises an exhaust assembly and an access assembly. The exhaust assembly is arranged at the other end of the top of the material guiding mechanism 2. The access assembly is arranged on the outer side of the exhaust assembly.

[0039] Through the cooperation between the exhaust assembly and the access assembly, the dust suppressant can be added according to the principle of Venturi tube, and the dust suppressant is atomized under the impact of high airflow and continuously blows towards the coal material to form an airflow barrier.

[0040] Preferably;

[0041] As Figure 3 and 4 shown, the drive assembly includes a curtain cover 313, which is provided at the top of the material guide mechanism 2, and a motor 31 is bolted to the top of the inner cavity of the curtain cover 313. The output shaft of the motor 31 is key-connected with a first bevel gear 32. The motor 31 realizes power output operation, and the first bevel gear 32 can transmit force when rotating and change the axial direction of the rotating force in cooperation with a second bevel gear 33.

[0042] As Figure 4 shown, the transmission assembly includes the second bevel gear 33, which is engaged at the bottom of the first bevel gear 32. An axle 34 is fixedly installed on the inner side wall of the second bevel gear 33 and rotationally connected with the curtain cover 313. Two flat gears 35 are fixedly installed on the surface of the axle 34. The power transmission operation can be realized according to the above-mentioned engagement transmission mode.

[0043] As Figure 4 shown, the extension assembly includes a toothed plate 36, which is engaged on one side of the flat gear 35. A curtain mounting plate 37 is fixedly installed on one side of the toothed plate 36. The extension adjustment is realized according to the engagement driving effect to change the adjustment of the curtain opening degree.

[0044] As Figure 5 shown, the shielding assembly includes a curtain mounting seat 38, which is bolted to the bottom of the curtain mounting plate 37. A curtain body 39 is fixedly installed on the bottom of the curtain mounting seat 38. The coal material conveyed in the material guide groove can be directly blocked and shielded to prevent dust leakage.

[0045] As Figure 5 shown, the sliding assembly includes a limiting plate 310, which is fixedly installed inside the curtain cover 313. A sliding groove 311 is formed on one side of the limiting plate 310. A sliding block 312 is slidingly connected inside the sliding groove 311. The sliding block 312 is fixed to the outside of the curtain mounting plate 37. The auxiliary limiting operation can be realized, and the sliding block 312 can avoid shaking to ensure the stability during the up-down extension adjustment.

[0046] As shown in the figure, the height position of the existing curtain is not adjusted. When adjustment is needed, the motor 31 is started first. The motor 31 drives the first bevel gear 32 through the connecting shaft. As shown in the figure, the connecting shaft is located between the first bevel gear 32 and the motor 31. When the first bevel gear 32 rotates, it will engage and drive the rotation of the second bevel gear 33. At this time, the second bevel gear 33 will change the vertical rotating force to the horizontal rotating force, thereby changing the axial direction of the force.

[0047] After that, the second bevel gear 33 directly drives the shaft rod 34 to rotate, and the shaft rod 34 drives the two groups of spur gears 35 to rotate synchronously. When the spur gears 35 rotate counterclockwise, the toothed plate 36 and the curtain mounting plate 37 mounted on one side of the toothed plate 36 are driven to move downward through the meshing relationship. During the downward movement of the curtain, the bottom curtain mounting seat 38 and the curtain body 39 are synchronously extended downward, thereby realizing the adjustment operation.

[0048] In addition, when the curtain mounting plate 37 extends downward for adjustment, the two groups of sliding blocks 312 are synchronously driven to slide in the corresponding sliding grooves 311, so as to limit the downward extension of the curtain mounting plate 37 and ensure the stability of movement.

[0049] Based on the above, during the transmission of the belt, the belt speed sensor monitors the rotating speed of the belt, so as to adjust the opening and closing angle of the curtain during operation, that is, the upward and downward extension position, when the belt speed sensor monitors the fast rotating speed of the belt, the curtain moves upward, so that the contact area with the coal is reduced, on the contrary, when the belt speed is slow, the curtain moves downward, so as to increase the contact area, and ensure that the curtain will not be thrown by the running belt while blocking and preventing dust overflow.

[0050] Further;

[0051] As shown in Figure 7 The exhaust assembly includes a venturi body 41, which is fixedly installed at the other end of the top of the material guiding mechanism 2 in a penetrating manner. The exhaust end of the venturi body 41 is communicated with an exhaust pipe 43. The venturi body 41 is used for accessing gas, and then can discharge the gas downward at high speed according to its own principle and cooperate with the exhaust pipe 43, and forms a gas curtain.

[0052] As shown in Figure 7 The access assembly includes an access pipe 42, which is communicated with the gas inlet end of the venturi body 41. The side surface of the venturi body 41 is communicated with a liquid inlet pipe 44. The access pipe 42 is used for connecting an external air pump, so as to discharge the gas into the venturi body 41. The liquid inlet pipe 44 can send the gas during the exhaust and conveying process of the venturi body 41, so as to atomize and reduce the dust.

[0053] During dust suppression, the inlet pipe 42 is first connected to an external air pump through an external pipe. The generated gas then directly enters the interior of the inlet pipe 42 and is then diverted by the inlet pipe 42 to the interior of several rows of Venturi tube bodies 41. Based on the principle of the Venturi tube body 41, the incoming gas can be ejected. The Venturi tube consists of an inlet section, a contraction section, a nozzle, and a diffusion section. The fluid enters from the inlet section, passes through the gradually narrowing contraction section, where the flow rate increases and the pressure decreases. At the nozzle, the flow rate reaches the maximum and the minimum pressure. Then, it enters the diffusion section where the flow rate decreases and the pressure recovers. During this process, the inlet pipe 44 is connected to the external pump. At this time, the external pump can draw liquid or dust suppressant into the interior of the inlet pipe 44. When the liquid enters the interior of the inlet pipe 44, it is continuously transported into the interior of the Venturi tube body 41. At this time, it is in the process of high-speed airflow discharge. Under the impact of the high-speed airflow, the liquid will be directly atomized and discharged towards the coal. In addition, an air curtain barrier will be formed during this process.

[0054] In summary, the combined effect of the two sets of mechanisms described above can improve the dust collection rate. Installing a purification spray device in front of the dust-laden curtain allows dust-containing air to be moistened by automatically sprayed micro-droplets, causing the suspended solid particles to become heavier and eventually settle to the ground. This method not only helps remove airborne pollutants but also prevents dust already adhering to the curtain surface from re-entraining and causing secondary pollution. Through the dual effects of physical blocking and moist rinsing, the dust-laden curtain effectively reduces the concentration of coal dust in the airflow, improving the working environment.

[0055] at last;

[0056] The material guiding mechanism 2 includes a material blocking component and a support component. The material blocking component is located at the inner end of the support column 1, and the support component is located on the outer side of the material blocking component. Through the cooperation of the material blocking component and the support component, it can be assembled into a material guiding trough in the prior art.

[0057] in;

[0058] like Figure 2 As shown, the material blocking assembly includes an inner guide plate 21, which is bolted to the inner end of the support column 1. An anti-overflow skirt 22 is bolted to the bottom of the outer side of the inner guide plate 21, and a top cover plate 26 is bolted to the top of the inner guide plate 21. This serves to guide the material in a directional manner and prevent coal from overflowing.

[0059] The support assembly includes an outer side plate 23, which is bolted to the outside of the inner guide plate 21. A wear-resistant support slide plate 24 is bolted to the inner wall of the outer side plate 23. A flip cover plate 25 is rotatably connected to the outer side of the outer side plate 23 to adapt to the conveyor belt and improve its sealing effect. The above structure achieves double sealing and reduces dust leakage.

[0060] The side edges of the conveying belt are located between the anti-overflow skirt 22 and the wear-resistant support slide 24, thus achieving double protection, and depending on the bolted manner, it is simple to assemble and convenient to replace individually, and achieves the effect of directional flow under the condition of ensuring sealing.

[0061] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely divergences, modifications, replacements and variations of the embodiments, and the scope of the application is defined by the appended claims and their equivalents.
