Description

Technical Field

[0001] This utility model relates to the field of kiln feeding equipment, specifically a feeder for a hydraulic system of a lime vertical kiln. Background Technology

[0002] A lime kiln, also known as a lime calciner, is an industrial furnace used to calcine limestone to produce quicklime. It plays an important role in many industries such as building materials, steel smelting, and chemicals. The basic working principle of a lime kiln is to decompose the calcium carbonate in limestone into calcium oxide and carbon dioxide by heating it at high temperature. The crushed stone is poured into the lime kiln through a feeder, and then the lime kiln processes the poured stone into lime.

[0003] The existing feeder basically consists of a support frame, a carriage, a baffle plate, and a hydraulic cylinder. The carriage can move up and down inside the support frame. When the stone is about to enter the carriage, the hydraulic rod drives the baffle plate to extend, releasing the seal on the carriage. After the stone is poured out, the hydraulic cylinder drives the baffle plate to retract, completing the seal on the carriage. Then the carriage moves inside the support frame. When it reaches the top of the support frame, the hydraulic cylinder drives the baffle plate to release the seal on the carriage, allowing the stone inside the carriage to enter the lime kiln, where it is processed into lime. To ensure the quality of the processed lime, manufacturers ensure that the volume difference of the stone poured into the lime kiln is not too large. Therefore, manufacturers generally install filter plates on the carriage to filter the poured stone and prevent excessively large stones from entering the carriage. However, during filtration, some stone gets stuck on the filter plate, which adversely affects the filtration efficiency. In this case, the operator needs to stop the machine for a period of time to manually clean it, which reduces the lime production efficiency to some extent. Utility Model Content

[0013] Compared with the prior art, this utility model provides a feeder for a hydraulic system of a lime vertical kiln, which has the following advantages:

[0014] When the crusher pours the crushed stones into the vehicle, the stones first come into contact with the filter plate. The filter plate screens the stones, and stones that are too large will slide on the outer surface of the filter plate and eventually leave the vehicle. As the filter plate filters the stones, the weight of the stones themselves causes the filter plate to move. One side of the filter plate rotates around a movable column inside the vehicle. Simultaneously, the filter plate is in a compressed state via a spring driven by a moving part. Once the filter plate has finished screening the stones, and there is no longer any pressure applied to it, the spring is released. Based on the spring's elasticity, the spring then drives the filter... The filter plate moves upward to reset. After the filter plate returns to its initial position, it has moved to its limit position. However, the spring still has some potential energy that has not been released. Therefore, the filter plate will collide with the limit position to a certain extent. Under the impact force of this collision, the stones stuck inside the filter plate will be ejected, thus cleaning the filter plate. Then, the vehicle moves inside the cabinet and finally pours the stones inside the vehicle into the lime kiln for lime processing. This structure realizes the automatic cleaning of stones stuck inside the filter plate without the need for manual cleaning by the operator, thus ensuring lime production efficiency to a certain extent.

[0024] The support frame 1 has two sliding grooves 11 inside, and each sliding groove 11 is fixedly equipped with a toothed plate 12. The outer surface of the vehicle body 3 is slidably connected to the inner surface of the support frame 1. Two power components are fixedly installed on one side of the vehicle body 3. Each power component extends into the two sliding grooves 11 on both sides. The outer surface of each power component meshes with the two toothed plates 12. The power components include two connecting gears 13, which are respectively located inside the two sliding grooves 11 and mesh with the two toothed plates 12. A connecting shaft 14 is fixedly provided between the two support frames 1. Two connecting brackets 15 are sleeved on the outer surface of the connecting shaft 14. The connecting shaft 14 is rotatably connected to the two connecting brackets 15. One side of the two connecting brackets 15 is fixedly connected to one side of the vehicle body 3. A transmission gear 16 is sleeved on the outer surface of the connecting shaft 14. The transmission gear 16 is fixedly connected to the connecting shaft 14.

The output end of the hydraulic cylinder 21 is slidably connected to the protective frame 20 and fixedly connected to the baffle plate 19.

[0026] When the vehicle body 3 is in motion, the baffle plate 19 is used to prevent the stone material inside the vehicle body 3 from leaking out and to avoid falling stones damaging the equipment, thereby improving the safety of the equipment to a certain extent. When the filter plate 4 moves around the movable column 5, the telescopic rod 10 will drive the T-shaped block 8 to move inside the T-shaped groove 9 to ensure that the movement trajectory of the filter plate 4 is not interfered with, and at the same time to prevent the spring 7 from getting tangled when the filter plate 4 rotates.

[0028] The working principle and usage process of this utility model are as follows: When the crusher pours the crushed stone into the vehicle body 3, the stone first contacts the filter plate 4. The filter plate 4 screens the poured stone. Stones that are too large will slide on the outer surface of the filter plate 4 and finally leave the interior of the vehicle body 3. While the filter plate 4 is filtering the stone, the weight of the stone itself causes the filter plate 4 to move. One side of the filter plate 4 rotates around the movable column 5 inside the vehicle body 3. At the same time, the filter plate 4 is driven by the T-block 8 to compress the spring 7. After the filter plate 4 has finished screening the stone, there is no more pressure on the filter plate 4, and the drive of the spring 7 is released. According to the extensibility of the spring 7, the spring 7 drives the filter plate 4 to move upward to reset. After the filter plate 4 returns to the initial position, the filter plate 4 has moved to the limit position of the extension rod 10, while the spring 7 is still... Some potential energy is not released, so the potential energy of spring 7 will generate an impact force on filter plate 4 due to the limit position of telescopic rod 10. Under the impact force, the stones stuck inside filter plate 4 will be ejected from filter plate 4, completing the cleaning of filter plate 4. Then, motor 18 drives transmission gear 16 meshing with it to rotate through drive gear 17, so that transmission gear 16 drives connecting gear 13 to rotate through connecting shaft 14. Connecting gear 13 moves upward around toothed plate 12 meshing with it, so that connecting gear 13 drives vehicle body 3 to move upward through connecting shaft 14 and connecting frame 15. When vehicle body 3 moves to the back of support frame 1, hydraulic cylinder 21 extends and drives baffle plate 19 to move, releasing the baffle plate 19 from the vehicle body 3. The stones inside vehicle body 3 begin to be fed into lime kiln 2 for lime production.
