Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for cleaning molybdenum concentrate roasting return brick kilns, and specifically discloses a device for cleaning furnace knots. Background Technique

[0002] The molybdenum concentrate roasting process is a typical exothermic reaction. Under industrial production scale conditions, it can be self-heated completely. The application of the project of "self-heating roasting method and device for molybdenum concentrate" independently developed by our company has enabled the smelting company to embark on the green smelting path of carbon-free roasting, environmental protection and energy conservation. However, because the grades of molybdenum concentrate selected by each concentrator and the proportion of flotation agent added are different, when smelting reactions occur in the rotary kiln, materials will adhere to the kiln wall and form a ring blockage. This not only reduces the quality of the calcined products, but also increases the weight of the rotary kiln itself, indirectly causing wear of the rotary kiln bearings, seriously affecting the output of molybdenum oxide; if production is stopped for cleaning, the cost is relatively high and it will affect the company's benefits. Only tools can be used to clean the furnace knots of the rotary kiln. At present, the lengths of the tools used to clean the furnace knots of rotary kilns of different specifications are generally more than 30 meters. Cleaning the furnace knots manually has a high labor intensity and a harsh working environment. Summary of the Invention

[0018] In order to better understand the present utility model, the content of the present utility model will be further clarified below in conjunction with embodiments, but the content of the present utility model is not limited to the following embodiments only.

[0019] Combined with the attached Figures 1-3 ,this utility model's device for cleaning furnace nodules will be elaborated in detail. It includes a cleaning head 2 for cleaning furnace nodules. The cleaning head 2 is arranged at the front end of a control rod 6, and the rear end of the control rod 6 is arranged on a movable trolley 3 at the upper part of a support frame 1. The movable trolley 3 is movably connected to the support frame 1. A driving mechanism is arranged at the lower part of the support frame 1. The output end of the driving mechanism is connected to the movable trolley 3 through a connecting rod 11. Under the action of the driving mechanism, the movable trolley 3 can drive the cleaning head 2 to reciprocate axially along the support frame 1 through the control rod 6. When cleaning furnace nodules, the head of the cleaning head 2 is inserted into the rotary kiln close to the furnace nodules. The driving mechanism drives the movable trolley 3 to drive the cleaning head 2 to reciprocate axially along the support frame 1 through the control rod 6, and the cleaning head 2 scrapes the furnace nodules reciprocally, causing the furnace nodules to fall off, thus achieving the purpose of cleaning furnace nodules, avoiding the heavy and high-intensity manual labor of manual cleaning, reducing labor intensity, and improving labor efficiency.

[0020] As an optional design, preferably for the device for cleaning furnace nodules, at least two fixed seats are spaced apart on the movable trolley 3. The fixed seats are spaced apart along the axial direction of the control rod 6. A pressing plate 4 and a hoop 5 that are matched with the control rod 6 are respectively arranged on the fixed seats. An arc-shaped groove is arranged at the upper end of the pressing plate 4. The pressing plate 4 and the hoop 5 cooperate to press and fix the control rod 6 relative to the movable trolley 3. Through the pressing plate 4 and the hoop 5, the control rod 6 is detachably connected to the movable trolley 3, facilitating the disassembly of the control rod 6 and adjusting the movement to adjust the position of the cleaning head 2. It should be noted here that preferably the length of the control rod 6 is adjustable to ensure that the depth of the cleaning head 2 entering the kiln can be adjusted, realizing a wide range of furnace nodule cleaning.

[0021] As an optional design, preferably for the device for cleaning furnace nodules, the cleaning head 2 is in the shape of a mace, a hook, or a star, which can efficiently clean the furnace nodules near the outlet in the rotary kiln.

[0022] As an optional design, preferably for the device for cleaning furnace nodules, guide rails 7 are respectively arranged on the two cross beams on the upper part of the support frame 1. The guide rails 7 are U-shaped channel steels. A number of rollers 8 that are matched with the guide rails 7 are arranged at the bottom of the movable trolley 3. The movable trolley 3 is in rolling connection with the guide rails 7 through the rollers 8, reducing the vibration during the movement of the movable trolley 3 along the guide rails 7.

[0023] As an optional design, preferably for the device for cleaning furnace nodules, supporting rollers 9 for movably supporting the support frame 1 are respectively arranged at the front and rear ends of the upper part of the support frame 1. A V-shaped annular groove is arranged on the supporting rollers 9. The supporting rollers 9 support the control rod 6 to avoid situations such as deformation of the control rod 6, and it is also convenient to adjust the position of the cleaning head 2 relative to the movable trolley 3 by adjusting the extension amount of the control rod 6.

[0024] As an alternative design, it is preferred that for the device for cleaning the furnace scale, the driving mechanism is a reduction motor 12, the output end of the reduction motor 12 is connected to one end of a crank 10, the other end of the crank 10 is hingedly connected to one end of a connecting rod 11, and the other end of the connecting rod 11 is hingedly connected to the bottom of the movable trolley 3. During operation, the reduction motor 12 drives the crank 10 to rotate. When the crank 10 rotates, it drives the movable trolley 3 to reciprocate along the guide rail 7 through the connecting rod 11. When the movable trolley 3 moves, it drives the cleaning head 2 to reciprocate through the control rod 6 to clean the furnace scale. It should be noted here that since both ends of the connecting rod 11 are respectively hingedly connected to the crank 10 and the movable trolley 3, when the crank 10 rotates, while applying a force to the movable trolley 3 through the connecting rod 11 to make the movable trolley 3 reciprocate along the guide rail 7, a certain downward pulling force is also applied to the movable trolley 3, which is equivalent to increasing the self-weight of the movable trolley 3, enhancing the stability of the movable trolley 3, and preventing the movable trolley 3 from detaching from the guide rail 7 due to the excessive weight of the control rod 6 causing top-heaviness and bottom-lightness.

[0025] As an alternative design, it is preferred that for the device for cleaning the furnace scale, a movable base capable of vertical lifting and horizontal movement (not shown in the drawings) is provided at the bottom of the support frame 1. The support frame 1 is arranged on the movable base, which facilitates adjusting the height of the support frame 1 and also facilitates the transfer of the support frame 1. The movable base can be an existing truck, forklift, etc.

[0026] The working process of the present utility model is as follows:

[0027] During operation, first adjust the height of the support frame 1 so that the cleaning head 2 can extend into the rotary kiln. The driving mechanism drives the movable trolley 3 to drive the cleaning head 2 to move back and forth through the control rod 6. The cleaning head 2 reciprocally scrapes the furnace scale, causing the furnace scale to fall off, thereby achieving the purpose of cleaning the furnace scale, avoiding the heavy high-intensity manual labor of manual cleaning, reducing the labor intensity, improving the labor efficiency, and achieving the efficient cleaning of the furnace scale near the outlet inside the rotary kiln.

[0028] The above description is only for the application implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. The scope of rights of the present utility model cannot be limited thereby. Any equivalent changes made according to the technical solution of the present utility model should be covered within the protection scope of the present utility model.
