[0018] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0019] In the present disclosure, unless otherwise stated, directional words such as "upper, lower, top, and bottom" generally refer to the upper, lower, top, and bottom of the corresponding component in the direction of gravity when in use, and "inner and outer" refer to the inner and outer relative to the contour of the component or structure itself. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0020] like Figure 1 As shown, the present disclosure provides a material conveying and dust removal device, comprising: a conveyor belt 1; a material guide trough 2, which is arranged on both sides of the conveyor belt 1 and extends along the conveying direction of the conveyor belt 1; a feed pipe 3, which is arranged above the conveyor belt 1; a dust suppression hood 4, which is connected to the discharge end of the feed pipe 3 and is sealed to the top of the material guide trough 2; a dust suction device 5, which is arranged on the side of the dust suppression hood 4 away from the feed pipe 3 and with the feed port facing the conveyor belt 1; and a dust removal device 6, the feed end of which is connected to the dust suction device 5; a recovery device 100, which is connected to the dust removal device 6 and is arranged above the conveyor belt 1.

[0021] Through the above technical scheme, the material falls from the discharge pipe 3 onto the conveyor belt 1 and is transported through the conveyor belt 1. The material can be any solid powder or solid material. For example, in the present disclosure, the material is coal, and the guide trough 2 is arranged on both sides of the conveyor belt 1 to prevent dust from overflowing. The discharge pipe 3 is generally vertically or inclinedly arranged with a drop. A dust suppression hood 4 is connected to the discharge end of the discharge pipe 3, and the dust suppression hood 4 is sealed and connected to the top of the guide trough 2 to prevent dust leakage. The dust suppression hood 4 can expand and relieve the pressure of the induced wind generated by the blast effect of the coal crusher and the induced wind generated by the large drop of the discharge pipe 3 to relieve the pressure generated by the induced wind, prevent the positive pressure at the outlet of the discharge pipe 3 from being too large and causing dust leakage, and return large particles of dust to the conveyor belt 1. The remaining fine particles of dust enter the dust suction device 5 and then enter the dust removal device 6 for dust removal, thereby preventing dust from overflowing and leaking, and the collected materials in the dust removal device are recycled through the recovery device to prevent waste.

[0022] As an optional implementation, Figure 2 As shown, the dust suppression hood 4 is provided with an opening on the side facing the conveyor belt 1 to facilitate the materials falling onto the conveyor belt 1 to enter the dust suppression hood 4, and a buffer guide plate 15 is provided on the side of the dust suppression hood 4 close to the discharge pipe 3, that is, a buffer guide plate 15 is provided at the entrance of the dust suppression hood 4, and the buffer guide plate 15 buffers and guides the raised dust to allow the dust to enter the dust suppression hood 4.

[0023] Optionally, the buffer guide plate 15 is constructed in an arc shape and multiple pieces are arranged at intervals along the height direction. The discharge end of the buffer guide plate 15 is inclined upward in the direction away from the discharge pipe 3. The inclined setting can allow the dust raised from below to enter the dust suppression hood 4 along the buffer guide plate 15, and the dust falling on the buffer guide plate 15 can automatically slide down to prevent dust accumulation. The arc-shaped design avoids dead corners and makes the airflow smoother.

[0024] As an optional implementation, Figure 2 As shown, a damping plate 16 is provided on the side of the dust suppression hood 4 away from the discharge pipe 3. The damping plate 16 is provided at the outlet of the dust suppression hood 4 to weaken the kinetic energy of the dust gas. Large particles of dust settle due to insufficient kinetic energy and fall back to the surface of the conveyor belt 1 to be transported away, while small particles of dust enter the dust collection device 5.

[0025] Optionally, the damping plate 16 is constructed in an arc shape and multiple plates are arranged at intervals along the height direction. The discharge end of the damping plate 16 is tilted downward in the direction away from the discharge pipe 3, and the dust gas flows out along the damping plate 16. The tilted setting allows the dust falling on the damping plate 16 to slide automatically to prevent dust accumulation. The arc-shaped design avoids dead corners and makes the airflow smoother.

[0026] As an optional implementation, Figure 2 As shown, a flow collecting device 14 is provided at the feed port of the dust collecting device 5. The flow collecting device 14 is constructed as a conical structure and the bottom surface of the conical structure faces the outside of the feed port. The flow collecting device 14 reduces the area of ​​the feed port, thereby enhancing the negative pressure and ensuring that there is sufficient negative pressure in the dust collecting device 5 to prevent dust leakage. The conical structure can also play a role in guiding flow, and the dust flows along the surface of the conical structure into the dust collecting device 5.

[0027] As an optional implementation, Figure 3 As shown, the dust removal device 6 is constructed as a wet dust collector, and a nozzle 61 is provided at the top of the wet dust collector. The material conveying dust removal device also includes a water tank 11 and a water supply pump 10. The water tank 11 is connected to the nozzle 61 through the water supply pump 10. The dust passes through the dust suppression hood 4 and is mainly fine dust particles. Therefore, the dust collector is selected and designed to mainly remove fine dust particles. The wet dust collector is considered to be the best. The water in the water tank 11 enters the nozzle 61 through the water supply pump 10 and the water supply pipe 13 to remove dust. In other embodiments, other dust collectors may also be used, such as bag dust collectors, electrostatic dust collectors, etc.

[0028] Alternatively, if Figure 1 and Figure 3As shown, a dust suction fan 12 is provided on the top of the wet dust collector, and a guide plate 62 is provided inside the wet dust collector, that is, the wet dust collector is a self-excited wet dust collector. The dust suction fan 12 acts as the power of the dust suction device 5 to suck the dust into the dust removal device 6. At the same time, the dust suction fan 12 will suck the water mist sprayed by the nozzle 61 upward to form a water curtain. After the dust contacts the water curtain, it falls into the collecting hopper below the dust removal device 6. The guide plate 62 is tilted and can be provided with multiple pieces. On the one hand, it can buffer the wind force and prevent the impact force of the dust from being too large and breaking through the water curtain. On the other hand, the sprayed water droplets fall on the guide plate 62, and the dust gas flows along the guide plate 62, which can increase the contact time between the dust and the water, thereby further removing the dust. In other embodiments, the dust suction fan 12 can also be arranged on the dust suction device 5, and the wet dust collector removes dust by spraying water from the nozzle 61.

[0029] Alternatively, if Figure 1 and Figure 4 As shown, the recovery device 100 includes a filter press device 8, a feeding device 9 and a booster pump 7. The discharge end of the dust removal device 6 is connected to the feed end of the filter press device 8 through the booster pump 7. The discharge end of the filter press device 8 is arranged above the conveyor belt 1 and the feeding device 9 is arranged at the discharge end of the filter press device 8. The water outlet end of the filter press device 8 is connected to the water tank 11. When the coal-water concentration in the dust removal device 6 reaches a predetermined value, the booster pump 7 is turned on to allow the coal-water in the dust removal device 6 to enter the filter press device 8 for coal-water separation, and the separated water enters the water tank 11 for reuse. When the coal cakes of the filter press are completely filled, the feeding device 9 is turned on to crush the coal slime and discharge the coal slime evenly onto the conveyor belt 1 to avoid waste. By way of example, the feeding device 9 is a crusher, and the filter press device 8 selects a plate-and-frame filter press. The plate-and-frame filter press has a simple structure, is easy to operate, runs stably, is convenient to maintain, has a flexible range of filter area selection, occupies less space, and has strong adaptability to materials.

[0030] Alternatively, if Figure 3 As shown, a liquid level sensor 17 and a concentration sensor 18 are provided in the dust removal device 6. When the coal-water concentration in the dust removal device 6 reaches a predetermined value, for example, 15%, the booster pump 7 is started to discharge; when the liquid level in the dust removal device 6 is low, the water replenishment pump 10 replenishes water, and when the water level is too high, the water replenishment pump 10 is stopped to replenish water.

[0031] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0033] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
