Description

Technical Field

[0001] This invention belongs to the technical field of feeding devices, specifically a hydrogen storage alloy powder feeding device. Background Technology

[0002] Hydrogen storage alloy powder refers to powdered materials made from hydrogen storage alloys through specific processes (such as chemical reduction, electrochemical methods, and mechanical ball milling). There are many types of hydrogen storage alloy powders, which can be classified into various categories based on their composition and performance. Rare earth hydrogen storage alloy powder is the mainstream product in the market; it is a high-performance hydrogen storage material made by adding rare earth elements to hydrogen storage alloy powder. In addition, there are other types of hydrogen storage alloy powders, such as magnesium-based and titanium-based powders. Hydrogen storage alloy powders have wide applications in automobile manufacturing, aerospace, and hydrogen energy. The processing of hydrogen storage alloy powder requires feeding, necessitating the use of feeding devices. However, existing feeding devices often experience problems. Due to the powder's tendency to accumulate, the hydrogen storage alloy powder can clog the feed inlet, preventing feeding. Furthermore, the falling hydrogen storage alloy powder can generate dust, causing dust pollution and affecting the working environment and the health of operators. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a hydrogen storage alloy powder feeding device, which effectively solves the problems in the prior art where the hydrogen storage alloy powder clogs the feeding port due to the accumulation characteristics of the powder, and the dust is stirred up when the hydrogen storage alloy powder falls, causing dust to spread.

A spring is provided on the surface of each sliding rod. The two ends of each spring are fixedly connected to the sliding rod and the sliding sleeve, respectively. A transmission assembly is provided at the output end of the motor. The transmission assembly is connected to the impeller, the rotating disk and the two striking hammers. When the motor is running, it outputs power to the impeller, the rotating disk and the two striking hammers through the transmission assembly, so that the impeller and the rotating disk rotate and suck up dust, and the two striking hammers strike the two contact blocks to vibrate the feeding tank and prevent the discharge valve from being blocked.

[0005] Preferably, the transmission assembly includes a first bevel gear, which is fixedly installed at the output end of the motor. A first shaft is fixedly installed at the bottom of the first bevel gear, and a first bushing is rotatably installed on the surface of the first shaft. The first bushing is fixedly connected to the inner wall of the dust collection box through two first fixed rods, and the bottom end of the first shaft is fixedly connected to the impeller.

[0006] Preferably, a second bevel gear is meshed with one side surface of the first bevel gear, and a third bevel gear is meshed with the other side surface of the first bevel gear. A second shaft and a third shaft are fixedly installed on the sides of the second and third bevel gears that are far apart from each other. The surfaces of the second and third shafts are rotatably connected to the two sides of the dust collection box through a second bushing.

[0007] Preferably, a third bushing is rotatably mounted on one side of the surface of both the second and third shafts. Both third bushings are fixedly connected to the feeding tank via support rods. A fourth bevel gear is fixedly mounted on the opposite ends of the second and third shafts. A fifth bevel gear is meshed on one side of each of the fourth bevel gears. A fourth shaft is fixedly mounted on one side of each of the two fifth bevel gears. One end of each of the two fourth shafts extends into the interior of the two protective covers and is fixedly mounted with a first gear.

[0008] Preferably, a fourth bushing is rotatably mounted on the surface of each of the fourth shafts, and each of the fourth bushings is fixedly connected to the feeding tank via a second fixing rod.

[0009] Preferably, a second gear is meshed with one side of the first gear, and the two second gears are rotatably connected to the inner walls of the two protective covers through a shaft seat.

[0010] Preferably, a first sprocket is fixedly installed in the middle of the surface of the second shaft, a first positioning strip is fixedly installed on one side of the bottom of the feeding tank, a second sprocket is rotatably installed on the lower part of one side of the first positioning strip, and a chain is meshed between the second sprocket and the first sprocket.

[0011] Preferably, a sixth bevel gear is fixedly installed on the side of the second sprocket away from the first positioning bar, and a second positioning bar is rotatably installed on the side of the sixth bevel gear away from the second sprocket, with the top of the second positioning bar fixedly connected to the feeding tank.

[0012] Preferably, a bevel gear ring is meshed with the lower part of the surface of the sixth bevel gear, and the bottom of the bevel gear ring is fixedly installed on the top of the rotating disk.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) When feeding materials, the operator opens the feeding valve and starts the motor at the same time to drive the first bevel gear to rotate. When the first bevel gear rotates, it drives the first shaft to rotate along the inside of the first shaft sleeve. When the first shaft rotates, it drives the impeller to rotate and draw in air. When the impeller rotates and draws in air, it draws the dust agitated during feeding into the filter hopper inside the dust collection box through two hoses, the mounting ring, and the rotating disc. Excess air is discharged through two air outlets. When there is a lot of dust in the filter hopper, the operator rotates the threaded cover to remove it from the dust collection box, so that the filter hopper can be taken out for cleaning through the connecting rod.

[0015] When the first bevel gear rotates, it drives the second and third bevel gears to rotate. When the second and third bevel gears rotate, they drive the second and third shafts to rotate along the inside of the two second and three shaft sleeves. When the second shaft rotates, it drives the first sprocket to rotate. When the first sprocket rotates, it drives the second sprocket to rotate along the first positioning strip via the chain. When the second sprocket rotates, it drives the sixth bevel gear to rotate along the second positioning strip. When the sixth bevel gear rotates, it drives the rotating disk to rotate along the mounting ring via the bevel gear ring. This allows for even and comprehensive dust collection, improving the dust collection effect.

[0016] (2) When the second shaft and the third shaft rotate, they both drive the fifth shaft to rotate through the fourth bevel gear. When the fifth bevel gear rotates, it drives the fourth shaft to rotate along the inside of the fourth shaft sleeve. When the two fourth shafts rotate, they both drive the second gear to rotate through the first gear. When the second gear rotates, it drives the push wheel to intermittently push the hammer. When the hammer is pushed, it drives the sliding sleeve to slide along the surface of the sliding rod through the transmission rod, and simultaneously squeezes the spring. The two springs will quickly push the two hammers to reset and strike the two contact blocks through their own elastic force, thereby causing the feeding tank to vibrate. When the feeding tank vibrates, it can disperse the accumulated hydrogen storage alloy powder and avoid blockage of the feeding valve.

[0017] (3) This feeding device can disperse the accumulated hydrogen storage alloy powder during feeding, preventing the powder from clogging the feeding valve, and can evenly and comprehensively remove the dust stirred up when the hydrogen storage alloy powder falls, thus avoiding the dust from affecting the working environment and the health of the operators.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1, by Figures 1 to 8The present invention includes a feeding tank 1, with support legs 2 fixedly installed on the lower parts of both sides of the feeding tank 1, protective covers 3 fixedly installed on the middle parts of both sides of the feeding tank 1, a discharge valve 4 fixedly installed at the bottom of the feeding tank 1, a mounting ring 5 provided on the surface of the discharge valve 4, a rotating disk 6 rotatably installed at the lower part of the mounting ring 5, a dust collection box 8 fixedly installed at the front of the feeding tank 1, a motor 7 fixedly installed at the middle of the top of the dust collection box 8, a threaded cover 10 threadedly connected to the bottom of the dust collection box 8, flexible hoses 9 fixedly installed on both sides of the bottom of the threaded cover 10, the bottom ends of the two flexible hoses 9 fixedly connected to the mounting ring 5, an impeller 14 provided in the middle of the interior of the dust collection box 8, a connecting rod 11 fixedly installed on the top of the threaded cover 10, a filter hopper 12 fixedly installed on the top of the connecting rod 11, air outlets 13 opened on both sides of the top of the dust collection box 8, and contactors fixedly installed on both sides of the feeding tank 1 inside the two protective covers 3. Block 15, two hammers 16 are symmetrically and rotatably installed inside the two protective covers 3. A transmission rod 33 is rotatably installed on the side of the two hammers 16 that is far away from each other. A sliding sleeve 34 is rotatably installed at one end of each transmission rod 33. A sliding rod 36 is inserted into the inside of each sliding sleeve 34. The upper part of each sliding rod 36 is fixedly connected to the inner wall of the two protective covers 3. A spring 35 is provided on the surface of each sliding rod 36. The two ends of each spring 35 are fixedly connected to the sliding rod 36 and the sliding sleeve 34 respectively. The output end of the motor 7 is provided with a transmission assembly. The transmission assembly is connected to the impeller 14, the rotating disk 6 and the two hammers 16. When the motor 7 is running, it outputs power to the impeller 14, the rotating disk 6 and the two hammers 16 through the transmission assembly, so that the impeller 14 and the rotating disk 6 rotate and suck up dust, and the two hammers 16 strike the two contact blocks 15 to vibrate the feeding tank 1 and prevent the discharge valve 4 from being blocked.

[0031] During feeding, the operator opens the feeding valve 4 and simultaneously starts the motor 7 to drive the transmission component. When the transmission component is running, it drives the impeller 14 to rotate and draw in air. When the impeller 14 rotates and draws in air, the dust stirred up during feeding is sucked into the filter hopper 12 inside the dust collection box 8 through the two hoses 9, the mounting ring 5, and the rotating disc 6. Excess air is discharged through the two air outlets 13. When there is a lot of dust in the filter hopper 12, the operator rotates the threaded cover 10 to remove it from the dust collection box 8, so that the filter hopper 12 can be taken out for cleaning through the connecting rod 11. At the same time, the operation of the transmission component also drives the rotating disc 6 to rotate along the mounting ring 5, so that the dust can be sucked evenly and comprehensively, improving the dust suction effect.

[0032] When the transmission component is running, it will intermittently push the hammer 16. When the hammer 16 is pushed, it will drive the sliding sleeve 34 to slide along the surface of the sliding rod 36 through the transmission rod 33, and at the same time squeeze the spring 35. The two springs 35 will quickly push the two hammers 16 to reset and strike the two contact blocks 15 through their own elastic force, thereby causing the feeding tank 1 to vibrate. When the feeding tank 1 vibrates, it can disperse the accumulated hydrogen storage alloy powder and avoid clogging the discharge valve 4. This allows the feeding device to disperse the accumulated hydrogen storage alloy powder during feeding, avoid the powder clogging the discharge valve 4, and evenly and comprehensively dissipate the hydrogen storage alloy powder. When it falls, it will stir up dust and suck it away, avoiding the dust affecting the working environment and the health of the operators.
