DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] The utility model provides a pneumatic conveying device for calcium carbide powder, such as Figure 1-Figure 3 As shown, it includes a hopper 1, the bottom end of the hopper 1 is connected to a material buffer bin 3, so that the material can be buffered after falling, the bottom of the material buffer bin 3 is connected to a mixing bin 5, one end of the mixing bin 5 is connected to an air conveying pipe 6, which is convenient for compressed air input, and the other end of the mixing bin 5 is connected to a pneumatic conveying pipe 4, which is convenient for conveying the mixed material to the material bin, an inclined plate 33 is installed inside the material buffer bin 3, a plug valve 2 is installed at the connection between the bottom end of the hopper 1 and the material buffer bin 3, and a narrowing tube 54 is arranged inside the mixing bin 5 to compress the air, suck in the material falling from the material buffer bin 3, and convey it together to the air conveying pipe 6.
[0022] In this embodiment, one end of the air conveying pipe 6 away from the mixing bin 5 is connected to an air pump, and one end of the pneumatic conveying pipe 4 away from the mixing bin 5 is connected to the material bin.
[0023] Specifically, a fixed block 34 is installed inside the material buffer bin 3 below the inclined plate 33. The fixed block 34 is fixed on the inner wall of the material buffer bin 3. A buffer spring 341 is installed between the upper surface of the fixed block 34 and the lower surface of the inclined plate 33, so that the inclined plate 33 can have a certain buffer space after being impacted by the material to avoid deformation and damage.
[0024] Furthermore, a feed port 31 is provided at the top of the material buffer bin 3, and a discharge port 32 is provided at the bottom of the material buffer bin 3. The feed port 31 is connected to the bottom of the gate valve 2 through a flange to facilitate the passage of materials from top to bottom.
[0025] Furthermore, a material inlet 51 is provided at the top of the mixing bin 5, a mixing outlet 52 is provided at one end of the mixing bin 5, and an air inlet 53 is provided at the other end of the mixing bin 5. The wide end of the narrowing tube 54 is connected to the air inlet 53, and the narrow end of the narrowing tube 54 is aligned with the mixing outlet 52. The material inlet 51 is connected to the discharge port 32 through a flange, the mixing outlet 52 is detachably connected to one end of the pneumatic conveying pipe 4, and the air inlet 53 is detachably connected to one end of the air conveying pipe 6, so as to facilitate the discharge of the material after mixing with the air.
[0026] Furthermore, a large particle impurity channel 55 is provided at the lower part of the interior of the mixing bin 5. Larger materials cannot be blown into the air conveying pipe 6 by air, and then fall into the large particle impurity channel 55 for collection. The large particle impurity channel 55 is inclined, and a large particle material discharge port 56 is provided at the lower end of the large particle impurity channel 55. A sealing cover is installed at the large particle material discharge port 56 to facilitate the discharge of larger particles of material after falling for recycling.
[0027] Furthermore, the upper end of the inclined plate 33 is rotatably connected to the inner wall of the material buffer bin 3 via a pin shaft, so as to facilitate the movement of the inclined plate 33 .
[0028] When the pneumatic conveying device for calcium carbide powder of the utility model is used, calcium carbide powder first falls from the hopper 1 into the material buffer bin 3. In this process, the gate valve 2 plays a role in controlling the material flow rate to ensure that the material falls smoothly and orderly. The design of the inclined plate 33 inside the material buffer bin 3 allows the material to be evenly distributed during the falling process and reduces the damage to the equipment caused by the impact force. At the same time, the buffer spring 341 and the fixed block 34 below the inclined plate 33 further absorb the impact force of the falling material to protect the equipment structure from damage.
[0029] Next, the material flows out from the discharge port 32 of the material buffer bin 3 and enters the material inlet 51 of the mixing bin 5 through the flange connection. In the mixing bin 5, the material meets the compressed air input from the air conveying pipe 6. The design of the narrowing pipe 54 allows the air to form a high-speed airflow in the mixing bin 5, sucking in and mixing the material. In this process, smaller material particles are carried by the airflow, while larger particles fall into the large particle impurity channel 55 due to gravity, and are finally discharged through the large particle material discharge port 56 for recycling.
[0030] Finally, the mixed material and air enter the pneumatic conveying pipeline 4 through the mixing outlet 52 and are efficiently conveyed to the material bin. During the entire conveying process, the pneumatic conveying device utilizes the energy of compressed air to achieve long-distance and high-efficiency conveying of calcium carbide powder, greatly improving production efficiency, reducing maintenance costs, and optimizing the operating process.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
