Description

Technical Field

[0001] The present application relates to the technical field of rotary kilns, and in particular to a rotary kiln blast pipe regulating device. Background Art

[0002] In the process of smelting using the conventional wet leaching process of roasted ore intensification, the existing zinc smelting enterprises produce acidic slag flotation tailings, iron slag and lead slag in the wet system. The lead slag is sold to lead smelting enterprises to recover lead. The acidic slag flotation tailings contain high zinc. The rotary kiln volatilization treatment process is selected to recover the zinc. At the same time, the heavy metal ions in the slag are recovered or solidified to achieve the harmlessness and resource utilization of the slag.

[0003] In the rotary kiln volatilization process, a large amount of compressed air needs to be transported into the kiln according to the production process, so a blast pipe is installed at the discharge end of the rotary kiln. In the actual production process, the depth and angle of the blast pipe into the kiln are adjusted in real time according to the redox reaction in the kiln, material fluidity, etc. The traditional method is to rely on multiple people to coordinate and adjust the traction rope and hand winch to change the depth and angle of the blast pipe into the kiln.

[0004] However, the blast pipe is close to the slag outlet. If the operating conditions are unstable, flashback may occur, leading to safety accidents such as scalding. Summary of the invention

[0044] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.

[0045] Embodiment 1:

[0046] See also Figures 1 to 3 , a rotary kiln blast pipe regulating device, the rotary kiln blast pipe regulating device further comprising:

[0047] Gantry 1;

[0048] A walking mechanism 2 is arranged at the bottom of the gantry 1;

[0049] An up-down adjustment mechanism 3 is arranged at both ends of the top of the gantry 1, and two up-down adjustment mechanisms 3 are provided, wherein a swing adjustment mechanism 4 is provided on the top of one of the up-down adjustment mechanisms 3, and a first bracket 5 is movably mounted on the swing adjustment mechanism 4, and a second bracket 6 is fixed on the top of the other up-down adjustment mechanism 3, and a blast pipe is set up between the first bracket 5 and the second bracket 6;

[0050] Among them, when the up and down adjustment mechanism 3 is in action, the first bracket 5 and the second bracket 6 are driven to drive the two ends of the blast pipe to rise and fall. When the swing adjustment mechanism 4 is in action, the first bracket 5 on its top is driven to drive one end of the blast pipe to swing. When the walking mechanism 2 is in action, the first bracket 5 and the second bracket 6 above it are driven to drive the blast pipe to move.

[0051] Specifically, the walking mechanism 2 is rotatably installed at the bottom of the gantry 1, and the movement of the gantry 1 is realized by the walking mechanism 2; the up-down adjustment mechanism 3 is fixedly installed or detachably installed at the two ends of the top of the gantry 1, and the end of the top provided with the swing adjustment mechanism 4 is set as the tail end, and the other end of the gantry 1 is the front end; the first bracket 5 at the tail end is movably connected with the swing adjustment mechanism 4, and the first bracket 5 is moved left and right through the action of the swing adjustment mechanism 4, and the second bracket 6 at the front end is fixedly connected or detachably connected with the up-down adjustment mechanism 3, and in the natural state, the first bracket 5 is flush with the second bracket 6;

[0052] When in use, the blast pipe is placed on the first bracket 5 and the second bracket 6, and the two up-down adjustment mechanisms 3 are operated to make the first bracket 5 and the second bracket 6 rise or fall, thereby driving the front end and the rear end of the blast pipe to rise and fall. If the two up-down adjustment mechanisms 3 are operated separately, the heights of the front end and the rear end of the blast pipe can be changed respectively, so that the blast pipe is set at an angle; the first bracket 5 at the rear end is moved left and right by the action of the swing adjustment mechanism 4, so that the rear end of the blast pipe is swung; the gantry 1 is driven to move by the action of the walking mechanism 2, thereby driving the first bracket 5 and the second bracket 6 to move synchronously, and then driving the blast pipe to move;

[0053] In the present embodiment, the upper and lower adjustment mechanisms 3 are provided to achieve the adjustment of the upper and lower angles of the blast tube (i.e., lifting adjustment), the swing adjustment mechanism 4 is provided to achieve the adjustment of the left and right angles of the tail end of the blast tube (i.e., swing adjustment), and the walking mechanism 2 is provided to achieve the forward and backward movement of the blast tube. The depth and angle of the blast tube entering the kiln are adjusted through the above three processes, instead of relying on the coordinated cooperation of multiple people to adjust the traction rope and the hand winch to adjust the depth and angle of the blast tube entering the kiln, thereby avoiding safety accidents such as scalding caused by backfire if the working conditions are unstable.

[0054] Embodiment 2:

[0055] See also Figure 2 Based on the first embodiment, optionally, the up and down adjustment mechanism 3 includes:

[0056] A pair of screw lifters 7 are fixed to the upper end surface of the gantry 1, and a double-output shaft reducer 8 is arranged between the pair of screw lifters 7. The two output shafts of the double-output shaft reducer 8 are respectively connected to the pair of screw lifters 7, and the input shaft of the double-output shaft reducer 8 is connected to an up and down adjustment motor 9.

[0057] Specifically, the up-down adjustment motor 9 is installed on the upper end surface of the gantry 1 and is located on one side of the double-output shaft reducer 8. The up-down adjustment motor 9 is connected to the power supply through the controller. The output shaft of the up-down adjustment motor 9 is fixedly connected to the input shaft of the double-output shaft reducer 8. The two output shafts of the double-output shaft reducer 8 are respectively fixedly connected to a pair of screw lifters 7. That is to say, a pair of screw lifters 7 are respectively provided below the first bracket 5 and the second bracket 6;

[0058] The up and down adjustment motor 9 is decelerated by a double-output shaft reducer 8. The two output shafts of the double-output shaft reducer 8 respectively drive a pair of screw lifters 7 to rotate. The screw lifters 7 can convert rotational motion into linear motion, so that the swing adjustment mechanism 4 and the first bracket 5 can be lifted and lowered synchronously, and the second bracket 6 can be lifted and lowered.

[0059] See also Figure 3 and Figure 4 Optionally, the swing adjustment mechanism 4 includes:

[0060] A mounting seat 10 is fixed to the upper end of the screw lifter 7, and a plurality of steel balls 11 are rotatably mounted in the mounting seat 10;

[0061] The lower end surface of the first bracket 5 is in rolling contact with the steel ball 11 , and the bottom of the first bracket 5 is threadedly connected to a screw rod 12 , one end of the screw rod 12 is connected to a handle 13 , and the screw rod 12 is driven to rotate by the handle 13 so that the first bracket 5 slides on the steel ball 11 .

[0062] Specifically, the lower end surface of the first bracket 5 is embedded in the mounting seat 10 and is in rolling contact with the steel ball 11. A screw hole is provided at the bottom of the first bracket 5 to allow a screw rod 12 to enter. The screw rod 12 is threadedly connected to the bottom of the first bracket 5 through the screw hole. The screw rod 12 can convert rotational motion into linear motion. When the screw rod 12 rotates, the rotational motion of the screw rod 12 is converted into linear motion of the first bracket 5, so that the bottom of the first bracket 5 slides on the steel ball 11, thereby realizing the left and right swinging of the first bracket 5; the end of the screw rod 12 away from the first bracket 5 is fixedly connected to the handle 13, and the rotation of the screw rod 12 is realized through the handle 13.

[0063] See also Figure 5 Optionally, the walking mechanism 2 includes:

[0064] A base 14 is fixed to the lower end of the gantry 1 , and a main shaft 15 is mounted on both sides of the lower end of the base 14 , and wheels 16 are installed at both ends of the main shaft 15 .

[0065] Specifically, two main shafts 15 are provided, which are rotatably mounted on both sides of the lower end of the base 14, and wheels 16 are installed at both ends of the main shaft 15. The rotation of the main shaft 15 drives the wheels 16 to rotate synchronously, thereby realizing the movement of the device.

[0066] It should be noted that the installation of the main shaft 15 and the wheel 16 is prior art and will not be further described here.

[0067] See also Figure 5 Optionally, the walking mechanism 2 further includes:

[0068] A travel drive motor 17 is arranged at the upper end of the base 14 , and the output shaft of the travel drive motor 17 is connected to a travel reducer 18 . Sprockets 19 are provided on the output shafts of the main shaft 15 and the travel reducer 18 . The two sprockets 19 mesh with the chain 20 to form a transmission structure.

[0069] Specifically, the travel drive motor 17 is decelerated by the travel reducer 18, and the two sprockets 19 are fixedly connected to the output shaft of the travel reducer 18 and the main shaft 15 respectively. The chain 20 engages with the two sprockets 19 to transmit the torque of the travel reducer 18 to the main shaft 15, thereby realizing the rotation of the main shaft 15 and then the rotation of the wheel 16.

[0070] See also Figure 6 Optionally, the lower end of the base 14 is further provided with an anti-dumping positioning mechanism 21, and the anti-dumping positioning mechanism 21 includes a positioning screw 22 and a mounting shaft 23;

[0071] A connecting plate for mounting the positioning screw 22 extends from the lower end of the base 14 . The threaded section of the positioning screw 22 passes through the connecting plate and abuts against the side wall of the mounting shaft 23 . The lower end of the mounting shaft 23 is rotatably connected to a roller 24 .

[0072] Specifically, a hole with a certain depth is opened on the side wall of the installation shaft 23. The threaded section of the positioning screw 22 passes through the connecting plate and enters the hole to be rotatably connected thereto. When the positioning screw 22 rotates, the installation shaft 23 is driven to move linearly, thereby driving the roller 24 to move synchronously linearly.

[0073] See also Figure 6 , Optionally, a track 25 is provided at the lower end of the wheel 16;

[0074] The position of the mounting shaft 23 is adjusted by rotating the positioning screw 22 so that the roller 24 abuts against or is separated from the inner side of the track 25 .

[0075] Specifically, by rotating the positioning screw 22 to drive the installation shaft 23 to move linearly, the roller 24 is driven to move linearly synchronously, and then the roller 24 is abutted against or separated from the inner side of the track 25. When the roller 24 abuts against the inner side of the track 25, the device is supported by the inner side of the track 25, and the overall operating stability of the device is improved, thereby preventing the device from tipping over.

[0076] Optionally, graduated scales are installed on the walking mechanism 2, the up-and-down adjustment mechanism 3 and the swing adjustment mechanism 4.

[0077] Specifically, by installing a scale ruler (not shown in the figure) on the walking mechanism 2, the depth of the rotary kiln blast pipe entering the kiln can be digitally and quantitatively controlled. By installing a scale ruler on the up and down adjustment mechanism 3, the up and down angular positions of the rotary kiln blast pipe in the rotary kiln can be digitally and quantitatively controlled. By installing a scale ruler on the swing adjustment mechanism 4, the left and right angular positions of the rotary kiln blast pipe in the rotary kiln can be digitally and quantitatively controlled.

[0078] It should be noted that, in order to achieve digital quantitative adjustment of the depth and angle of the blast pipe entering the kiln, the installation position of the scale ruler is easy to think of by those skilled in the art, so the specific installation position of the scale ruler is not further elaborated in this embodiment.

[0079] See also Figure 5 Optionally, a chain tightener 26 is provided on one side of the chain 20 .

[0080] Specifically, when the chain 20 is loose during the operation of the device, the chain tensioner 26 can quickly identify and take corresponding measures to prevent the chain 20 from falling off. The chain tensioner 26 usually detects the position and tension of the chain 20. Once the chain 20 is found to be loose, the chain tensioner 26 will automatically adjust and re-tighten the chain 20 to restore the chain 20 to a normal working state.

[0081] It should be noted that the structure of the chain tensioner 26 is prior art and will not be further described here.

[0082] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings are not related to the specific objects, and the dimensions of the objects can be changed arbitrarily.
