Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical equipment, in particular to a zinc waste recycling smelting feeding device. Background Art

[0002] Hydrometallurgy is currently the most important zinc smelting method in the world, which includes roasting, leaching, purification, electrolysis and casting. Zinc roasted sand is the main raw material for hydrometallurgy. In the existing production, the raw material of zinc roasted sand is increasingly in short supply, and the quality is unstable and the composition content is complex. As a result, the hydrometallurgy process generally faces problems such as low zinc smelting efficiency, insufficient purity, unstable quality and low efficiency. Therefore, it is necessary to improve the quality stability of the raw material zinc roasted sand and pre-treat the zinc roasted sand before roasting to make it have good air permeability and heat transfer, as well as considerable thermal strength, which is of vital importance to the optimized production and large-scale production of zinc. When processing it, the zinc waste needs to be transported to facilitate subsequent treatment.

[0003] The publication number of the existing public technology is: CN211246300U. A feeding device for zinc smelting is composed of a bracket, a lifting device, a mixing device, a granulator and a basic base. The lifting device is tilted on the bracket, a hopper is provided above the bottom end of the lifting device, and a mixed feed bin is provided at the top. The bottom of the mixed feed bin is connected to the mixing device, and the discharge port of the mixing device is connected to the granulator. The utility model makes the zinc raw material have better air permeability and heat transfer through mixed granulation, improves the quality stability of the zinc raw material, meets the roasting conditions, and is conducive to the optimized production and large-scale production of zinc.

[0004] The existing technology has the following problems:

[0005] The zinc waste is fed through a lifting device, but the zinc waste directly discharged from the hopper will impact the conveyor belt of the lifting device, which may easily damage the conveyor belt in the long run, thereby affecting the subsequent feeding operation. In addition, impurities such as dust are easily attached to the zinc waste, which are easily attached to the conveyor belt during feeding. The above patent does not involve the removal of impurities attached to the conveyor belt. In the long run, the attachment of impurities will not only increase the weight of the conveyor belt, resulting in increased operating consumption, but also the impurities are likely to corrode the conveyor belt, causing damage to the conveyor belt, which not only reduces its service life, but also affects the feeding operation of the zinc waste. The overall use effect is not very ideal.

[0006] To this end, we proposed a zinc waste recycling smelting feeding device to solve the above-mentioned drawbacks. Utility Model Content

[0007] The utility model aims to solve the shortcomings in the prior art and proposes a zinc waste recycling, smelting and feeding device.

[0008] Material toggling mechanism, its both sides respectively have the support of the support frame, and the support frame has the support frame, and the support frame has the support frame, and the support frame has the support frame and the support frame has the support frame.

[0009] Preferably, a chip groove is provided below the bottom of one side surface of the loading crawler, and several groups of cleaning plates are obliquely installed inside the chip groove. Brushes and cleaning nozzles are respectively installed on the top surfaces of the cleaning plates, and the brushes are in contact with the loading crawler.

[0010] Preferably, a plurality of groups of hydraulic legs are symmetrically rotatably connected at both sides of the bottom of the frame.

[0011] Preferably, a water inlet pipe is provided on the surface of one side of the frame, one end of the water inlet pipe is connected to an external water pump, and the other end is connected to the cleaning nozzle.

[0012] Preferably, a collection box is installed at the bottom of the frame just below the chip discharge groove.

[0013] Preferably, the size of the limiting rod is matched with the size of the hole at the bottom of the sealing plate.

[0014] Preferably, the fixing plate is located above the loading crawler.

[0015] Preferably, a motor bracket is provided below the driving motor, and the motor bracket is welded to the frame.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model adopts a moving box. During operation, the zinc waste discharged from the hopper can be loaded through the moving box. As the materials are continuously accumulated, the moving box will continue to fall, and when it falls to a certain height, the sealing plate on its surface will contact the limit rod. Then, as the moving box continues to fall, the sealing plate will gradually move out of the moving box due to the fixation of the limit rod, so that the bottom of the moving box is opened. At this time, the zinc waste inside will fall to the surface position of the loading crawler. Since the height difference between the moving box and the loading crawler is small when the moving box is finally discharged, the damage to the loading crawler caused by the impact of the materials can be well avoided, and the service life of the crawler is delayed. It has the advantages of feed buffering and long service life of the crawler.

[0018] (2) The utility model adopts a brush and a cleaning nozzle. During operation, the driving motor can drive the driving roller to rotate, and then the driven roller and the supporting roller can drive the feeding crawler to load the zinc waste on its surface. When the feeding crawler rotates to the bottom, the inclined brush will first wipe the surface of the feeding crawler to remove the attached waste. Then, the emergency nozzle can spray water to flush the stubborn waste, improve the cleanliness of the feeding crawler, avoid the attachment of waste leading to an increase in the weight of the feeding crawler, and then cause an increase in energy consumption in subsequent operations. The utility model has the advantages of being a little busy in cleaning the crawler. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In this embodiment: a chip removal groove 16 is opened at the lower bottom of the surface of one side of the loading crawler 4, and a plurality of cleaning plates 15 are installed obliquely inside the chip removal groove 16. A brush 14 and a cleaning nozzle 13 are installed on the top surface of the cleaning plate 15, and the brush 14 is in contact with the loading crawler 4.

[0029] Specifically, the chip discharge groove 16 is provided to smoothly discharge the processed impurities into the collecting box 20 to facilitate subsequent processing.

[0030] In this embodiment, two sides of the bottom of the frame 1 are symmetrically connected to a plurality of hydraulic legs 19 for rotation.

[0031] Specifically, the hydraulic legs 19 are provided to support and fix the device and adjust the height, so as to facilitate better use of the device.

[0032] In this embodiment, a water inlet pipe 18 is provided on the surface of one side of the frame 1 , one end of the water inlet pipe 18 is connected to an external water pump, and the other end is connected to the cleaning nozzle 13 .

[0033] Specifically, the water inlet pipe 18 is provided to introduce flushing water for use.

[0034] In this embodiment, a collecting box 20 is installed at the bottom of the frame 1 just below the chip discharge groove 16 .

[0035] Specifically, the collection box 20 is provided to collect scraped waste materials and flushing waste water for use, so as to facilitate subsequent processing.

[0036] In this embodiment, the size of the limiting rod 11 matches the size of the hole at the bottom of the sealing plate 10 .

[0037] Specifically, the size setting ensures that the limiting rod 11 can be smoothly incorporated into the bottom of the limiting plate, thereby achieving the purpose of fixing and dragging the sealing plate 10.

[0038] In this embodiment: the fixing plate 12 is located above the loading crawler 4 .

[0039] Specifically, the position of the fixing plate 12 is set to avoid contact with the feeding crawler 4 during use, which causes the feeding crawler 4 to be unable to be smoothly moved and used.

[0040] In this embodiment: a motor bracket is provided below the driving motor 21 , and the motor bracket is welded to the frame 1 .

[0041] Specifically, the motor bracket is provided to support and fix the drive motor 21, and the drive motor 21 is used to drive the feeding crawler 4 to run, thereby ensuring that the zinc waste feeding operation can be carried out smoothly.

[0042] In this embodiment, the driven roller, the driving roller and the supporting roller are common knowledge in the art and are only used without modification, so the control method and circuit connection are not described in detail.

[0043] Working principle: When working, the personnel can set the device just below the zinc waste hopper and align the mobile box 7 with the bottom of the hopper. Then, the driving motor 21 can drive the driving roller 17 to rotate, and then the driven roller 2 and the supporting roller 3 can drive the feeding crawler 4, so that the zinc waste on its surface can be loaded. Then, when the feeding crawler 4 rotates to the bottom, the inclined brush 14 will first wipe the surface of the feeding crawler 4 to remove the attached waste, and then the feeding crawler 4 will be cleaned by the brush 14. The emergency nozzle can spray water to flush stubborn waste, improve the cleanliness of the feeding crawler 4, avoid the attachment of waste to increase the weight of the feeding crawler 4, and thus increase the energy consumption of subsequent operations. In addition, the personnel can selectively set a wiping structure behind the cleaning nozzle 13, such as a water-absorbing cloth or a fan, to achieve a drying structure for the feeding crawler 4. Before the zinc waste is transported, the zinc waste falling from the hopper will first fall into the mobile box 7. Due to the increase in the overall weight, the mobile box 7 will move slowly. When the waste zinc in the moving box 7 reaches a certain weight, the sealing plate 10 on its surface will contact the limiting rod 11. As the moving box 7 continues to fall, the limiting rod 11 will fix the sealing plate 10, and the moving box 7 will continue to fall. At this time, due to the influence of dragging, the sealing plate 10 will fall off from the inside of the moving box 7, and then the bottom of the moving box 7 will be opened. At this time, the waste zinc in the moving box 7 will fall to the surface position of the feeding crawler 4. Since the height difference between the moving box 7 and the feeding crawler 4 is small when the moving box 7 is finally discharged, the damage of the feeding crawler 4 caused by the impact of the materials can be well avoided, and the service life of the crawler can be delayed. After the internal material is discharged, the moving box 7 can be lifted as a whole due to the reset of the spring 5. Then the moving box 7 can drive the sealing plate 10 to detach from the limiting plate. At this time, due to the influence of gravity, the sealing plate 10 will continue to slide down to realize the sealing operation of the bottom of the moving box 7, which is convenient for the subsequent falling operation of the waste zinc in the hopper. The device as a whole has the advantages of feed buffering, crawler cleaning and long crawler service life.
