Description

Technical Field

[0001] The present invention relates to the field of powder conveying, and specifically, to a dust collection device for powder raw material conveying and suction capture. Background Art

[0002] Powder is a kind of fine solid particulate matter. When powder is being produced and processed, it will go through multiple processes. In order to avoid impurities in the powder production process, dust removal operations are generally carried out during the production process. Generally, the production of powder starts from the original block-shaped raw materials and finally forms powder through various processes. When the powder raw materials are conveyed through the conveyor belt, they are often affected by external dust and doped therein. Moreover, there will also be a certain amount of dust in the packaging and transportation of the powder raw materials in the previous process. Therefore, when carrying out subsequent conveyor belt conveying and packaging, in order to avoid the doping of internal dust, dust collection and capture operations are generally carried out to reduce the accumulation of internal dust. Generally, the dust collection operation is to set a semi-closed dust collection hood at the top of the conveyor belt. However, the dust collection effect of this kind of semi-closed dust collection hood is not good during actual use, and the achievable dust collection efficiency is relatively low. And because it is fixedly installed, there is no function of adjusting dust collection, which is very inconvenient for subsequent maintenance.

[0003] Regarding the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0004] The purpose of the present invention is to provide a dust collection device for powder raw material conveying and suction capture to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A powder raw material conveying, dust suction and collection device, including a frame. At the four corners of the bottom of the frame, legs are fixedly installed. At the bottom ends of the legs, feet are installed. A bottom frame is arranged directly below the frame, and the end of the bottom frame is fixedly connected to the legs. A conveyor belt is installed outside the frame. A support rod is hingedly installed on the outside of the frame. Above the frame, a dust suction mechanism is symmetrically arranged along the center. The outer side of the bottom of the dust suction mechanism is hinged to the top end of the support rod. A blowing mechanism is installed at the center of the bottom of the frame. A number of first air holes are opened on the conveyor belt. An adjusting mechanism is fixedly installed at the center of the top of the frame. The adjusting mechanism is arranged between the two dust suction mechanisms. The adjusting mechanism includes vertical rods fixed on both sides of the center of the top of the frame. At the top ends of the vertical rods, a top plate spanning the conveyor belt is fixedly installed. At the bottom between the two vertical rods, a bottom plate is also fixedly installed directly below the top plate. At the center of the top of the bottom plate, a lead screw perpendicular to it is rotatably installed through a bearing seat, and the top end of the lead screw penetrates through the center of the top plate. Between the top plate and the bottom plate, a lifting block is also provided. A nut sleeve is fixedly installed through the center of the lifting block, and the nut sleeve is screwed on the outside of the lead screw. At one end of the lifting block facing the two dust suction mechanisms on both sides, a first hinge seat is fixedly installed. On the first hinge seat, a traction rod is hingedly installed. The end of the traction rod away from the first hinge seat is hinged to the outside of the adjacent dust suction mechanism.

[0006] Through the above technical solution, the powder raw material to be dusted is placed on the conveyor belt for conveying. During the conveying process, when the blowing mechanism is started, the powder raw material on the conveyor belt can be blown through the first air holes. At the same time, the dust suction mechanism above the frame can also centrally collect the dust blown by the blowing mechanism. When the lead screw is rotated, the lead screw will drive the lifting block to move up and down through the nut sleeve. The movement of the lifting block will drive the traction rod to move synchronously through the first hinge seat. At this time, the traction rod can traction the dust suction mechanism to adjust the height on the top of the frame through the support rod, changing the distance between the dust suction mechanism and the conveyor belt, so that the dust suction mechanism can achieve a better dust suction effect.

[0007] Furthermore, guide rods are fixedly installed between the top plate and the bottom plate. Guide sleeves are also fixedly installed through the lifting block. The guide rods penetrate through the guide sleeves. A turning handle is fixedly installed at the top end of the lead screw.

[0008] Through the above technical solution, the assembly setting of the guide rod and the guide sleeve can make the lifting block more stable when adjusting up and down.

[0009] Further, the blowing mechanism includes a air supply hood arranged at the center of the bottom of the frame. The air supply hood is arranged along the length direction of the frame. A air supply pipe is communicated with the outer wall on one side of the air supply hood. A blower is fixedly installed on the top of the bottom frame. The output end of the blower is connected with the air supply pipe through a connecting pipe. A support plate is fixedly installed on the top of the frame. A second air hole is opened in the middle of the support plate. The air supply hood is fixedly installed at the bottom of the support plate and is arranged opposite to the second air hole.

[0010] Through the above technical solution, when the blower is started, the blower can supply air to the inside of the air supply hood, and the air in the air supply hood can be blown to the conveyor belt through the second air hole, and then the powder raw material on the conveyor belt can be blown through the first air holes on the conveyor belt.

[0011] Further, an additive box is also installed on the top of the bottom frame. The additive box is communicated with the input end of the blower. Conveyor rollers are rotatably installed at both ends of the frame. Guide rollers are also rotatably installed at the positions near both ends of the bottom of the frame. The conveyor belt is arranged outside the conveyor rollers and the guide rollers. A tensioning roller is installed between the conveyor roller and the guide roller at one end of the bottom of the frame. A stabilizing frame is also arranged between the frame and the bottom frame. The end of the stabilizing frame is also connected to the support leg. A conveyor motor is fixedly installed at one end of the top of the stabilizing frame. A driving sprocket is fixedly installed at the end of the output shaft of the conveyor motor. A driven sprocket is fixedly installed at the end of the mounting shaft of the conveyor roller near the conveyor motor. The driving sprocket and the driven sprocket are connected by a transmission chain.

[0012] Through the above technical solution, some additives for improving the separation of raw materials and dust can be added to the additive box, so that the dust can be ensured to be separated from the powder while blowing. The tensioning roller is used to adjust the tightness of the conveyor belt to ensure the stable conveying of the conveyor belt.

[0013] Further, the dust collection mechanism includes an assembly frame. A dust collection hood is installed on the top of the assembly frame. A connecting hood is fixedly installed at the end of the top of the dust collection hood. A top hood is fixedly installed at the end of the top of the connecting hood. A dust collection pipe is installed at the center of the top of the top hood. The dust collection pipe is communicated with the inside of the top hood. A second hinge seat is fixedly installed on the outer wall of the assembly frame facing the adjusting mechanism. One end of the traction rod away from the first hinge seat is connected to the second hinge seat. Hinge shafts are fixedly installed on the outer walls of both sides of the assembly frame arranged along the length direction of the frame. The top end of the support rod is rotatably connected to the hinge shaft.

[0014] Through the above technical solution, the dust collection hood is used to collect dust in the top area of the conveyor belt. By connecting the end of the dust collection pipe to an external exhaust dust removal system, the dust in the area above the conveyor belt can be absorbed through the dust collection hood.

A locking handle is installed on the side of the top of the assembly frame away from the first hinge.

[0016] Through the above technical solution, the locking handle and the notch can be used to position the corner plate so that the dust hood can be stably assembled on the assembly frame. By unscrewing the locking handle, the dust hood can be flipped over using the first hinge so that the bottom of the dust hood is separated from the assembly frame, making it convenient to maintain and clean the inside of the dust hood.

[0017] Furthermore, a plurality of inclined grille plates are fixedly installed inside the bottom end of the dust hood, and an observation port is provided at the bottom center of a side surface of the dust hood close to the first hinge and / or corner plate, and a shield is provided outside the observation port, the area of the shield is larger than the area of the observation port, and the top of the shield is installed on the outer wall of the dust hood through a second hinge, and an observation window is provided on the shield.

[0018] Through the above technical solution, the grille plate can guide the airflow inside the dust hood and can also absorb dust to a certain extent. By lifting the shield, the grille plate can be directly observed or cleaned through the observation port, and the situation at the bottom of the dust hood can be directly observed through the observation window without lifting the shield.

[0020] Through the above technical solution, when an external force is applied to the rocker arm, the assembly shaft can be rotated, and then the baffle can be flipped over. The baffle can be used to block the inside of the connecting cover, and the inside of the connecting cover can be closed or opened according to actual working conditions.

[0021] Furthermore, a strip plate is provided on the outside of the connecting cover, a connecting shaft is fixedly installed on the end of the rocker arm away from the assembly shaft, and the end of the connecting shaft away from the rocker arm is rotatably installed on the strip plate. An extension shaft is integrally provided at the end of the assembly shaft located in the middle, and a handle is fixedly installed on the end of the extension shaft, and a locking hole is also provided on the handle.

[0022] Through the above technical solution, pulling the handle can drive the connected assembly shaft to rotate through the extension shaft.
