[0024] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the solid particle additive self-service feeding system of the MMA device of the utility model in conjunction with the accompanying drawings.

[0025] like Figures 1 to 7 As shown, a self-service feeding system for solid particle additives of MMA device includes a traveling crane device 6, and the traveling crane device 6 includes a platform 63. A support frame 62 is fixedly arranged above the platform 63, and a hook 61 is arranged on the top of the support frame 62. The hook 61 can slide along the top of the support frame 62, and the length of the hanging rope in the hook 61 can be controlled at will. A loader 3 is suspended at the bottom of the hook 61, and the loader 3 can move up and down under the control of the hook 61. The hook 61 is respectively provided with a receiver 2 and a support 5 below the moving track of the support frame 62. The caliber of the loader 3 is smaller than the caliber of the receiver 2 and the support 5, and there is a certain distance between the receiver 2 and the support 5. An additive preparation tank 1 is arranged below the receiver 2, and the additive preparation tank 1 and the support 5 are respectively arranged on the platform 63. A conveying mechanism 4 is also arranged above the platform 63, and the loader 3 moves in the conveying mechanism 4.

[0026] The receiver 2 includes a receiver cylinder 23, the bottom of which is a conical structure, a filling valve 21 is arranged between the receiver cylinder 23 and the additive preparation tank 1, the filling valve 21 controls the solid particles in the receiver cylinder 23 to be added into the additive preparation tank 1, a support ring gasket 22 is arranged in the receiver cylinder 23, the support ring gasket 22 is arranged at the top of the conical structure of the receiver cylinder 23, dust recovery mechanisms 25 are respectively arranged at the top and bottom of the receiver cylinder 23, and a receiver sealing ring 24 is arranged at the periphery of the top of the receiver cylinder 23.

[0027] The loader 3 includes a loader cylinder 35 and a conical discharge cylinder 33 connected together in the upper and lower parts. The radius of the top of the conical discharge cylinder 33 is larger than the inner diameter of the support ring pad 22. The conical discharge cylinder 33 can be stuck in the support ring pad 22. A cylinder discharge sealing ring 32 is arranged at the bottom of the conical discharge cylinder 33. The cylinder discharge sealing ring 32 is a conical structure. A sealing cover 37 is arranged above the loader cylinder 35. A sealing cover positioning ring 36 is arranged at the bottom of the sealing cover 37. The sealing cover positioning ring 36 is a structure that is narrow at the bottom and wide at the top as a whole. The sealing cover positioning ring 36 has a guiding function, which facilitates the sealing cover 37 to seal the solid particle additive in the loader cylinder 35. A valve core control rod 38 is provided through the center of the sealing cover 37, and a sealing valve core 31 is connected to the lower end of the valve core control rod 38. The sealing valve core 31 is arranged below the cylinder unloading sealing ring 32. The shape of the sealing valve core 31 matches the shape of the cylinder unloading sealing ring 32. The cylinder unloading sealing ring 32 is in close contact with the sealing valve core 31, which can prevent the solid particles in the loader 3 from flowing out from the bottom of the conical unloading cylinder 33. The top of the valve core control rod 38 is connected to the hook 61, and the hook 61 controls the valve core control rod 38 to move up and down, thereby controlling the sealing valve core 31 to block or open the conical unloading cylinder 33. A plurality of control rod positioners 34 for limiting the valve core control rod 38 are arranged in the loader cylinder 35. The control rod positioner 34 includes a positioning bracket 341 connected to the inner wall of the loader cylinder 35. A positioning ring 342 is arranged in the positioning bracket 341. The valve core control rod 38 passes through the positioning ring 342 in the control rod positioner 34 in sequence. The control rod positioner 34 can limit the position of the valve core control rod 38 in the loader cylinder 35 so that the valve core control rod 38 is always in the center position of the loader cylinder 35.

[0028] The conveying mechanism 4 includes a guide rail support frame 43 disposed above the platform 63. Two sliding guide rails 41 are disposed in parallel on the top of the guide rail support frame 43. The distance between the sliding guide rails 41 is greater than the diameter of the carrier cylinder 35 and less than the diameter of the sealing cover 37. A support seat 42 is disposed at the end of the sliding guide rail 41. The support seat 42 is disposed above the support 5. The support seat 42 can limit the moving stroke of the carrier 3. When the carrier 3 touches the support seat 42, the carrier 3 is directly above the support 5.

[0029] The supporter 5 includes a supporter cylinder 51 and a dust recovery mechanism 25 disposed on the upper portion of the supporter cylinder 51 . The dust recovery mechanism 25 can absorb dust in the supporter cylinder 51 .

[0030] The dust recovery mechanism 25 includes an induced draft main ring pipe 252 arranged on the outside of the receiver cylinder 23 or the support cylinder 51, an induced draft control valve 251 is arranged on one side of the induced draft main ring pipe 252, and a plurality of branch ring pipes 253 are arranged on the induced draft main ring pipe 252, and the branch ring pipes 253 pass through the outer wall of the receiver cylinder 23 or the support cylinder 51.

[0031] When in use, the hook 61 in the overhead crane 6 moves on the support frame 62, and the hook 61 moves the carrier 3 filled with solid particle additives to the top of the receiver 2, and the hook 61 is controlled to vertically drop the carrier 3 into the receiver 2. During the falling process of the carrier 3, the sealing cover 37 on the carrier 3 first contacts the receiver sealing ring 24, and the sealing cover 37 contacts the receiver sealing ring 24 to form a closed space in the receiver cylinder 23. The carrier 3 continues to fall, and the sealing cover 37 separates from the carrier cylinder 35, and the conical discharge cylinder 33 contacts the receiver. The support ring pad 22 in the receiver 2 is in contact with the support ring pad 22. Under the support of the support ring pad 22, the loader 3 is stably set inside the receiver 2. After the loader 3 is stable, the filling valve 21 is opened, and the valve core control rod 38 is controlled to move downward, so that the sealing valve core 31 is away from the cylinder unloading sealing ring 32, and a gap is formed between the sealing valve core 31 and the cylinder unloading sealing ring 32. The solid particle additive in the loader 3 falls into the additive preparation tank 1 due to gravity, and the dust generated by the falling solid particle additive in the receiver cylinder 23 is sucked into the induced draft main ring pipe 252 through the branch ring pipe 253. The process of filling the solid particle additive is carried out in the sealed receiver cylinder 23, and the generated powder is absorbed by the dust recovery mechanism 25, which improves the safety of operation.

[0032] The control rod positioner 34 has a guiding function when the valve core control rod 38 and the conical blanking sealing valve core 31 move.

[0033] After the loader 3 completes the discharge of the solid particle additive, the filling valve 21 is closed, the induced draft control valve 251 of the dust recovery mechanism 25 on the receiver cylinder 23 is closed, and the loader 3 is lifted by the hook 61 in the overhead lifting device 6. The hook 61 hooks the valve core control rod 38 and moves upward. The sealing valve core 31 enters the cylinder unloading sealing ring 32 to lift the loader cylinder 35, and the sealing cover positioning ring 36 enters the loader cylinder 35. The sealing cover 37 contacts the loader cylinder 35 to form a sealed space in the loader cylinder 35 to prevent dust from escaping from the loader 3.

[0034] The lifted material loader 3 enters between the two sliding guide rails 41 and moves toward the top of the support 5 under the control of the hook 61. When the support cylinder 51 contacts the support seat 42, the material loader 3 is just above the support 5. The hook 61 controls the material loader 3 to fall into the support cylinder 51. During the falling process of the material loader 3, the sealing cover 37 contacts the sliding guide rails 41 and stops the falling action. The sealing cover 37 stays between the sliding guide rails 41 under the action of the sealing cover positioning ring 36, and the material loader cylinder 35 continues to fall. When the top of the material loader cylinder 35 falls to the bottom of the dust recovery mechanism 25 in the support 5, the hook 61 stops moving, opens the dust recovery mechanism 25 on the support 5, and feeds into the material loader 3. Most of the dust generated during the feeding process is absorbed by the dust recovery mechanism 25, which reduces the overflow of dust in the workplace and ensures that the staff is in a safe working environment.

[0035] After the feeding is completed, the dust recovery mechanism 25 in the support 5 is closed, the hook 61 lifts the sealing valve core 31, and after the loader cylinder 35 is lifted between the sliding guide rails 41, the sealing cover 37 falls onto the loader cylinder 35, so that the loader 3 forms a closed space, and then the hook 61 in the lifting device 6 lifts the loader 3 to the top of the receiver 2 for the next round of filling of solid particle additives.
