[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 5 An embodiment of this utility model provides a novel anti-blocking feeding device for a calcium carbide furnace silo, comprising a support 1, a feeding hopper 2 disposed on the inner side of the support 1, an anti-blocking mechanism 3 disposed at the bottom of the feeding hopper 2, the anti-blocking mechanism 3 being used to actively push the blocked raw material, and a vibration mechanism 4 disposed inside the feeding hopper 2, the vibration mechanism 4 being used to vibrate and loosen the blocked raw material.
[0034] The anti-blocking mechanism 3 includes a discharge channel 31. The top of the discharge channel 31 is fixedly connected to the bottom of the feeding hopper 2. A fixed seat 32 is fixedly connected to the top of the outer side of the discharge channel 31. Two hydraulic rods 33 are fixedly connected to the bottom left and right sides of the fixed seat 32. Lifting blocks 34 are fixedly connected to the bottom of multiple hydraulic rods 33. Push rods 35 are fixedly connected to the top of multiple lifting blocks 34. A detection component 36 is provided inside the feeding hopper 2. The detection component 36 includes an infrared sensor 361. The rear side of the infrared sensor 361 is fixedly connected to the rear side inside the feeding hopper 2. A protective cover 362 is fixedly connected to the front side of the infrared sensor 361. A sliding component 37 is provided on the opposite side of multiple push rods 35. The sliding component 37 includes multiple sliders 371. The adjacent sliders 371 are fixedly connected to the opposite side of multiple push rods 35. Multiple grooves 372 are opened inside the discharge channel 31.
[0035] Specifically, when the anti-blocking mechanism 3 is working, the discharge channel 31 receives the material falling from the feeding hopper 2, the hydraulic rod 33 at the bottom of the fixed seat 32 extends and retracts to drive the lifting block 34 to move up and down, and the push rod 35 at the top of the lifting block 34 moves in the discharge channel 31 accordingly. Through the cooperation of the hydraulic rod 33 and the lifting block 34, the push rod 35 clears the material inside the discharge channel 31.
[0036] In the detection component 36 inside the feeding hopper 2, the infrared sensor 361 detects the material flow status, and the protective cover 362 protects the infrared sensor 361. Through the cooperation of the infrared sensor 361 and the protective cover 362, the blockage can be monitored in real time.
[0037] In the sliding assembly 37 on the side away from the push rod 35, the slider 371 slides in the groove 372 inside the discharge channel 31. The cooperation between the slider 371 and the groove 372 ensures that the lifting process of the push rod 35 is stable and smooth.
[0038] During operation, when the infrared sensor 361 detects a blockage, the hydraulic rod 33 is activated, driving the push rod 35 to move up and down, pushing the blockage material. The slider 371 slides along the slide groove 372 to ensure the stable movement of the push rod 35. After the blockage is cleared, the hydraulic rod 33 is reset.
[0039] The push rod 35 is driven to move by the cooperation of the hydraulic rod 33 and the lifting block 34. The blockage is detected by the cooperation of the infrared sensor 361 and the protective cover 362. The stable movement of the push rod 35 is ensured by the cooperation of the slider 371 and the chute 372, thereby realizing the anti-blocking and unblocking of the discharge channel 31.
[0040] Reference Figure 2 , Figure 3 and Figure 4 The vibration mechanism 4 includes a fixed plate 41, the outer side of which is disposed on the inner side of the feeding hopper 2. A vibration motor 42 is fixedly connected to the top of the fixed plate 41. A transmission frame 43 is fixedly connected to the left and right sides of the top of the fixed plate 41. Mounting plates 44 are fixedly connected to the opposite sides of the multiple transmission frames 43. Mounting components 46 are provided on the top of the two mounting plates 44. Mounting components 46 include two pins 461. The bottom ends of the two pins 461 are fixedly connected to the top of the two mounting plates 44 respectively. Pin holes 462 are opened on the top of the two mounting plates 44. A fixing component 45 is provided on the top of the fixed plate 41. The fixing component 45 includes multiple bolts 451. The bottom ends of the multiple bolts 451 are threadedly connected to the four corners of the bottom of the vibration motor 42 respectively. Nuts 452 are threadedly connected to the bottom of the multiple bolts 451.
[0041] A buffer assembly 47 is provided on the inner side of the support 1. The buffer assembly 47 includes multiple buffer telescopic rods 471. The bottom of each buffer telescopic rod 471 is fixedly connected to the inner side of the support 1. Springs 472 are fixedly connected to the outer walls of each buffer telescopic rod 471. A support assembly 48 is provided on the top of the support 1. The support assembly 48 includes a support ring 481. The inner side of the support ring 481 is fixedly connected to the top outer side of the feeding hopper 2. Steering telescopic rods 482 are fixedly connected to the four corners of the top of the support 1.
[0042] Specifically, when the vibration mechanism 4 is working, the fixing plate 41 on the inner side of the feeding hopper 2 supports the vibration motor 42. The bolts 451 and nuts 452 of the fixing component 45 cooperate to fix the vibration motor 42 on the top of the fixing plate 41. The cooperation of the bolts 451 and nuts 452 ensures that the vibration motor 42 is installed firmly.
[0043] The transmission frame 43 on the top of the fixed plate 41 transmits the vibration force generated by the vibration motor 42 to the mounting plate 44. The pin 461 of the mounting assembly 46 is inserted into the pin hole 462. The cooperation between the pin 461 and the pin hole 462 enhances the stability of the connection between the transmission frame 43 and the mounting plate 44.
[0044] In the buffer assembly 47 inside the support 1, the buffer telescopic rod 471 cooperates with the spring 472 to provide buffering when the feeding hopper 2 vibrates. Through the cooperation of the buffer telescopic rod 471 and the spring 472, the impact of vibration on the support 1 is reduced.
[0045] In the support assembly 48 at the top of the bracket 1, the support ring 481 supports the feeding hopper 2, and the steering telescopic rod 482 adjusts the support angle in coordination with the vibration of the feeding hopper 2. Through the cooperation of the support ring 481 and the steering telescopic rod 482, the stability of the feeding hopper 2 during vibration is ensured.
[0046] During operation, the vibration motor 42 starts to generate vibration force, which is transmitted to the feeding hopper 2 through the transmission frame 43 and the mounting plate 44, causing the feeding hopper 2 to vibrate. The buffer component 47 reduces the vibration impact, and the support component 48 ensures stable vibration of the feeding hopper 2 and avoids material blockage.
[0047] The vibration motor 42 is fixed by the cooperation of bolts 451 and nuts 452, the vibration force is transmitted by the cooperation of transmission frame 43 and mounting plate 44, the impact is reduced by the cooperation of buffer telescopic rod 471 and spring 472, and the stability is ensured by the cooperation of support ring 481 and steering telescopic rod 482, so as to achieve effective vibration of feeding hopper 2.
[0048] Working principle: When raw materials are added into the feeding hopper 2, they move towards the discharge channel 31 at the bottom under their own gravity. The anti-blocking mechanism 3 starts working simultaneously. The infrared sensor 361 inside the feeding hopper 2 continuously detects the flow state of the internal material. The protective cover 362 at the front effectively prevents the raw materials from directly impacting the infrared sensor 361, ensuring that the detection process is not interfered with.
[0049] When the infrared sensor 361 detects that the material flow is obstructed and a blockage occurs, the signal is transmitted to the control terminal, triggering the anti-blocking action. Multiple hydraulic rods 33 at the bottom of the top fixed seat 32 on the outer side of the discharge channel 31 begin to extend and retract, driving the lifting block 34 at the bottom to move up and down. The push rod 35 at the top of the lifting block 34 moves synchronously inside the discharge channel 31. The slider 371 on the side away from the push rod 35 slides along the groove 372 on the inner side of the discharge channel 31. Through the cooperation of the slider 371 and the groove 372, it is ensured that the push rod 35 will not deviate during the lifting process, stably pushing the blocked material, breaking up the clumps and accumulated raw materials and pushing them downwards. After the unblocking is completed, the hydraulic rod 33 drives the push rod 35 to return to the initial position.
[0050] While the anti-blocking mechanism 3 is working, the vibration mechanism 4 is also started simultaneously. On the fixing plate 41 inside the feeding hopper 2, multiple bolts 451 of the fixing component 45 pass through the mounting holes at the bottom of the vibration motor 42 and are threadedly connected to the nuts 452 at the bottom, thus firmly fixing the vibration motor 42 to the top of the fixing plate 41. After the vibration motor 42 is started, it generates vibration force, which is transmitted to the mounting plate 44 on the opposite side through the transmission frame 43 at the top of the fixing plate 41. The pin 461 at the top of the mounting plate 44 is inserted into the corresponding pin hole 462, which enhances the stability of the connection between the transmission frame 43 and the mounting plate 44, so that the vibration force can be efficiently transmitted to the feeding hopper 2, causing the entire feeding hopper 2 to vibrate.
[0051] The buffer assembly 47 inside the support 1 plays a role in this process. Multiple buffer telescopic rods 471 extend and retract with the vibration of the feeding hopper 2. The springs 472 on the outer wall extend and retract synchronously to absorb the impact force generated by the vibration and reduce the impact on the support 1. In the support assembly 48 at the top of the support 1, the support ring 481 is close to the top of the outer side of the feeding hopper 2 to provide support. The steering telescopic rods 482 at the four corners flexibly adjust the support angle according to the vibration direction of the feeding hopper 2 to ensure that the feeding hopper 2 remains stable during vibration and does not shake excessively.
[0052] The push rod 35 of the anti-blocking mechanism 3 actively pushes the blocked raw material, and the vibration of the vibration mechanism 4 loosens the raw material, effectively preventing the feeding hopper 2 and the discharge channel 31 from becoming blocked, and ensuring that the raw material can be fed through the feeding device.
[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
