[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention realizes that the coal material being transported can be effectively blocked by installing a blocking curtain to block the coal dust particles carried in the wind flow and prevent it from spreading into the working environment through the setting of a blocking filter mechanism. The blocking curtain can reduce the impact of the wind flow on the material guide chute and reduce the wind speed, thereby reducing the diffusion and flying of dust.

[0023] 2. The present invention is provided with an atomizing mechanism, according to the principle of the Venturi tube, based on the Venturi effect, which is actually a phenomenon that when a fluid passes through a pipeline, an increase in flow velocity leads to a decrease in pressure. When the fluid passes through a gradually narrowing pipeline, the flow velocity will increase, and the pressure will decrease. In the Venturi tube, the flow velocity of the fluid increases and the pressure decreases in the contraction section, thereby forming the lowest pressure at the nozzle. After the fluid passes through the nozzle, it enters the diffusion section, the flow velocity decreases, and the pressure gradually recovers. The atomization dust reduction treatment is achieved according to the arrangement and in conjunction with the externally connected dust suppressant. The dust suppressant can be atomized and dust reduced under the impact of the above-mentioned high-speed gas, and an air curtain barrier is formed at the same time.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0034] The present invention provides a gas-solid coupling dust suppression material guide chute, comprising a support 1;

[0035] The inner end of the support 1 is provided with a guide mechanism 2 for coal spillage, one end of the top of the guide mechanism 2 is provided with a filter mechanism 3 for preventing dust from leaking out, and the other end of the top of the guide mechanism 2 is provided with an atomization mechanism 4 for dust suppression;

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

[0037] Through the cooperation among the driving assembly, the transmission assembly, the extension assembly, the shielding assembly and the sliding assembly, the dust-proof barrier for the coal in the material guide trough can be achieved, and the opening and closing degree of the curtain can be changed in an extendable and adjustable manner to adapt to the coal transportation.

[0038] The atomizing mechanism 4 comprises an exhaust component and an access component. The exhaust component is arranged at the other end of the top of the material guiding mechanism 2, and the access component is arranged at the outside of the exhaust component.

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

[0040] Preferred;

[0041] like Figure 3 and 4 As shown, the driving assembly includes a curtain cover 313, which is arranged on the top of the material guiding mechanism 2. The top of the inner cavity of the curtain cover 313 is bolted with a motor 31, and the output shaft key of the motor 31 is connected with the first bevel gear 32. The motor 31 realizes the power output operation, and the first bevel gear 32 can transmit the force during rotation, and cooperate with the second bevel gear 33 to change the axial direction of the rotation force.

[0042] like Figure 4 As shown, the transmission assembly includes a second bevel gear 33, which is meshed at the bottom of the first bevel gear 32. A shaft 34 is fixedly installed on the inner wall of the second bevel gear 33. The shaft 34 is rotatably connected to the curtain cover 313. Flat gears 35 are fixedly installed at both ends of the surface of the shaft 34. Power transmission operation can be achieved according to the above-mentioned meshing transmission method.

[0043] like Figure 4 As shown, the extension assembly includes a tooth plate 36, which is meshed with one side of the flat gear 35. A curtain mounting plate 37 is fixedly installed on one side of the tooth plate 36, and the extension adjustment function is realized based on the meshing drive to change the adjustment of the opening and closing degree of the curtain.

[0044] like Figure 5 As 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 at the bottom of the curtain mounting seat 38, which can directly block and shield the coal material transported in the material guide chute to prevent dust leakage.

[0045] like Figure 5 As shown, the sliding assembly includes a limit plate 310, which is fixedly mounted inside the curtain cover 313. A slide groove 311 is provided on one side of the limit plate 310. A slider 312 is slidably connected inside the slide groove 311. The slider 312 is fixed to the outer side of the curtain mounting plate 37, which can not only realize the auxiliary limit operation, but also prevent it from shaking, so as to ensure stability during the up and down telescopic adjustment.

[0046] As shown in the figure, the height position of the existing curtain is not adjusted. When it needs to be adjusted, the motor 31 is started first, and 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 mesh and drive the second bevel gear 33 to rotate. At this time, the second bevel gear 33 will change the vertical rotation force into a lateral rotation force, thereby changing the axial direction of the force;

[0047] Afterwards, the second bevel gear 33 directly drives the shaft 34 to rotate, and the shaft 34 drives the two sets of flat gears 35 to rotate synchronously. When the flat gear 35 rotates counterclockwise, it drives the toothed plate 36 and the curtain mounting plate 37 installed on one side of the toothed plate 36 to move downward together through the meshing relationship. During the downward movement of the curtain, the curtain mounting seat 38 and the curtain body 39 at the bottom can be synchronously driven to extend downward together, thereby realizing the adjustment operation;

[0048] In addition, when the curtain mounting plate 37 is extended downward for adjustment, the two sets of sliders 312 are synchronously driven to slide inside the corresponding slide grooves 311, so as to limit the position of the curtain mounting plate 37 when extending downward, thereby ensuring the stability of movement.

[0049] Based on the above, during the transmission process of the belt, the belt rotation speed is monitored by the position belt speed sensor, so as to adjust the opening and closing angle of the curtain when working, that is, the up and down extension position, according to the conveying speed of the belt. When the belt speed sensor detects that the belt rotation speed is fast, it moves upward to reduce the area contacting the coal. Conversely, when the belt speed is slow, it moves downward to increase the contact area, ensuring that the curtain will not be thrown away by the running belt while blocking the dust from overflowing.

[0050] further;

[0051] like Figure 7 As shown, the exhaust assembly includes a venturi tube body 41, which is fixedly installed at the other end of the top of the material guiding mechanism 2. The exhaust end of the venturi tube body 41 is connected to an exhaust pipe 43. The venturi tube body 41 is used to connect the gas and then can exhaust gas downward at high speed according to its own principle and in cooperation with the exhaust pipe 43, and an air curtain will be formed.

[0052] like Figure 7 As shown, the access component includes an access pipe 42, which is connected to the air inlet end of the venturi tube body 41. The side of the venturi tube body 41 is connected to a liquid inlet pipe 44. The access pipe 42 is used to connect an external air pump to discharge the gas into the venturi tube body 41, and the liquid inlet pipe 44 can deliver gas during the exhaust and transportation process of the venturi tube body 41, so as to cause the liquid to be atomized and dust-reduced.

[0053] When dust suppression is performed, the access pipe 42 is first connected to the external air pump through an external pipeline, and the generated gas will directly enter the interior of the access pipe 42, and then be diverted and transported by the access pipe 42 to the interior of several groups of venturi tube bodies 41 arranged in an array. According to the principle of the venturi tube body 41, the entered gas can be ejected. The venturi tube is composed 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, the flow rate increases, the pressure decreases, reaches the maximum flow rate and the lowest pressure at the nozzle, and then enters the diffusion section, the flow rate decreases, and the pressure is restored. In the process again, the connected liquid inlet pipe 44 is connected to the external pump. At this time, the liquid or dust suppressant can be discharged into the interior of the liquid inlet pipe 44 through the extraction of the external pump. When the liquid enters the interior of the liquid inlet pipe 44, it is continuously transported and enters the interior of the venturi tube body 41. At this time, it is in the high-speed airflow discharge. Under the impact of the high-speed airflow, the liquid will be directly atomized and discharged to the coal material, and an air curtain barrier will be formed in this process.

[0054] In summary, based on the cooperation of the above two groups of mechanisms, the dust capture rate can be improved. A purification spray device is installed in front of the curtain. When the dust-containing air flows through here, it will be moistened by the tiny water droplets that are automatically sprayed, making the solid particles originally floating in the air become heavy and eventually settle to the ground. This method not only helps to remove pollutants in the air, but also prevents the dust that has been attached to the curtain surface from flying again to form secondary pollution. Through the dual effects of physical blocking and wet flushing, the curtain can effectively reduce the concentration of coal dust in the windflow and improve the working environment.

[0055] at last;

[0056] The material guiding mechanism 2 includes a material blocking assembly and a supporting assembly. The material blocking assembly is arranged at the inner end of the pillar 1, and the supporting assembly is arranged at the outer side of the material blocking assembly. Through the cooperation of the material blocking assembly and the supporting assembly, they 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 1, an anti-overflow skirt plate 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, which plays a role in directional material guidance and can prevent coal from overflowing;

[0059] The support assembly includes an outer plate 23, which is bolted to the outer side of the inner guide plate 21. The inner wall of the outer plate 23 is bolted with a wear-resistant support slide plate 24. The outer side of the outer plate 23 is rotatably connected with a flap plate 25 for adapting to the conveyor belt to improve its sealing effect. The above structure is combined to achieve double sealing and reduce dust leakage.

[0060] The side of the conveyor belt is located between the anti-overflow skirt 22 and the wear-resistant support slide plate 24, thereby achieving double protection, and according to the bolting method, its assembly is simple and it is convenient for individual replacement, achieving a directional flow guidance effect while ensuring airtightness.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
