[0001] This utility model relates to the field of electrostatic dust removal technology, and in particular to an electrostatic dust removal device for flue gas used in the calcination of high-alumina bauxite. Background Technology

[0002] High-alumina bauxite, also known as high-alumina material, is mainly composed of gibbsite and high-alumina silica. The gibbsite content increases with the ratio of aluminum oxide to silicon dioxide. The minor minerals are rutile, succinate, etc., and sometimes small amounts of Baume and dickite are also present.

[0003] High-alumina bauxite generates a large amount of flue gas during calcination, which contains a significant amount of dust. Therefore, dust removal equipment is needed to remove the dust from the flue gas. However, existing dust removal equipment has the following problems:

[0004] The current system lacks the function of automatically detecting the dust removal effect of the electrostatic precipitator. When the electrostatic precipitator malfunctions, it is difficult for staff to repair it in a timely manner, thus affecting the dust removal effect on the flue gas. Therefore, an electrostatic dust removal device for flue gas in the calcination of high-alumina bauxite is proposed. Utility Model Content

[0027] The electrostatic precipitator is installed at the lower end of the mounting block.

[0028] Optionally, the driving component further includes:

[0029] There are two connecting rods, both of which are installed on the right end of the mounting block and are symmetrically arranged on the upper and lower sides of the cam.

[0030] There are two connecting rod cylinders, which are symmetrically fixedly installed on the left end of the drive box and symmetrically arranged on the upper and lower sides of the cam.

[0035] Compared with the prior art, the beneficial effects of this utility model are:

[0036] 1. In use, the flue gas electrostatic precipitator for high-alumina bauxite calcination allows the flue gas generated during calcination to enter the precipitator's casing through the inlet pipe. The electrostatic precipitator removes dust from the flue gas. The dust-removed flue gas then enters the detection box through the connecting pipe. A maximum value is first set for the controller. The dust concentration sensor collects dust concentration information from the flue gas and transmits it to the controller. The controller converts this dust concentration information into data and compares it with the maximum value. If the value is greater than or equal to the maximum value, it indicates that the dust concentration in the flue gas is too high, suggesting a possible malfunction of the electrostatic precipitator. The controller then sends a command to the alarm, which activates. Personnel then need to inspect and repair the electrostatic precipitator. This design enables dust removal from the flue gas generated after high-alumina bauxite calcination and allows for monitoring the dust removal effect of the electrostatic precipitator, facilitating timely maintenance.

[0037] 2. In operation, this electrostatic precipitator for high-alumina bauxite calcination flue gas rotates by starting the motor. The protruding end of the rotating cam strikes the right end of the mounting block, causing the mounting block to move to the left. At this point, the spring deforms. After the left-moving mounting block separates from the cam, the spring returns to its original deformation and, through the connecting rod, moves the mounting block to the right, thus causing the mounting block to vibrate left and right. This allows the dust adhering to the electrostatic precipitator to fall into the dust collection box. This design achieves the effect of automatic dust removal from the electrostatic precipitator.

Therefore, they should not be construed as limitations on this utility model.

[0049] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0050] like Figure 1-3As shown, this utility model embodiment provides an electrostatic dust removal device for flue gas from high-alumina bauxite calcination, including a dust removal device shell 1, an electrostatic precipitator 4, and a detection component 3. An air inlet pipe 2 is fixedly connected to the left end of the dust removal device shell 1. The electrostatic precipitator 4 is installed inside the top of the dust removal device shell 1 through a drive component 5. The detection component 3 is installed at the right end of the dust removal device shell 1.

[0051] The detection component 3 includes a detection box 301 and a dust concentration sensor 305. The left end of the detection box 301 is fixedly connected to a connecting pipe 302, and the left end of the connecting pipe 302 is fixedly connected to the right end of the dust removal equipment shell 1. The right end of the detection box 301 is fixedly connected to an air outlet pipe 304. The dust concentration sensor 305 is fixedly installed on the upper end of the detection box 301, and the lower end of the sensing end of the dust concentration sensor 305 passes through the upper end of the detection box 301 and extends into the interior of the detection box 301.

[0052] In this embodiment, a dust collection box 7 is also included. The dust collection box 7 is fixedly installed and connected to the lower end of the outer shell 1 of the dust removal equipment. The dust collection box 7 is located directly below the electrostatic precipitator 4.

[0053] The detection component 3 also includes a control box 306, a controller 307, and an alarm 308. The control box 306 is fixedly installed inside the top of the detection box 301. The controller 307 and the alarm 308 are both installed inside the control box 306. The dust concentration sensor 305 is electrically connected to the controller 307, and the controller 307 is electrically connected to the alarm 308.

[0054] The flue gas generated by the calcination of high-alumina bauxite can enter the dust removal equipment shell 1 through the air inlet pipe 2, and the electrostatic precipitator 4 can remove dust from the flue gas.

[0055] The electrostatic precipitator 4 is based on the authorized patent application number 202122264903.9, which is existing technology. Therefore, its specific structure and working principle will not be described in detail here. The flue gas after dust removal enters the detection box 301 through the connecting pipe 302. First, a maximum value is set for the controller 307. The controller 307 is an SC200 general-purpose controller. The dust concentration sensor 305 can collect the dust concentration information in the flue gas and transmit it to the controller 307. The controller 307 converts the dust concentration information into data and compares it with the maximum value. When it is greater than or equal to the maximum value, it means that the dust concentration in the flue gas is too high, and the electrostatic precipitator 4 may have malfunctioned. The controller 307 can then send a command to the alarm 308, and the alarm 308 can start to sound. The staff then need to inspect and repair the electrostatic precipitator 4.

[0056] The detection component 3 also includes two support rods 303. One end of each support rod 303 is symmetrically fixed to the lower end of the detection box 301, and the other end of each support rod 303 is symmetrically fixed to the right end of the dust removal equipment housing 1.

[0057] The support rod 303 can support the test box 301, thereby improving the stability of the test box 301 after installation.

[0058] like Figure 4-5 As shown, the drive assembly 5 also includes a drive box 505, a motor 506, a cam 507, and a mounting block 501. The drive box 505 is fixedly installed inside the top of the dust removal equipment housing 1. A through-hole is opened at the left end of the drive box 505. The motor 506 is fixedly installed inside the bottom of the drive box 505. The cam 507 is fixedly fitted onto the upper end of the output shaft of the motor 506. The mounting block 501 is slidably installed inside the top of the dust removal equipment housing 1. One end of the cam 507 passes through the through-hole and fits against the right end of the mounting block 501. The electrostatic precipitator 4 is installed at the lower end of the mounting block 501.

[0059] The drive assembly 5 also includes a connecting rod 503 and a connecting rod cylinder 504. There are two connecting rods 503, both of which are installed on the right end of the mounting block 501 and are symmetrically arranged on the upper and lower sides of the cam 507. There are two connecting rod cylinders 504, which are symmetrically fixedly installed on the left end of the drive box 505 and are symmetrically arranged on the upper and lower sides of the cam 507. The right ends of the two connecting rods 503 pass through the left ends of the two connecting rod cylinders 504 and extend into the interior of the connecting rod cylinders 504.

[0060] A spring 508 is fixedly installed on the right end of the connecting rod 503. The right end of the spring 508 is fixedly connected to the right end face inside the connecting rod cylinder 504. The outer end face of the connecting rod 503 slides and fits against the inner wall of the connecting rod cylinder 504 in the horizontal direction.

[0061] By starting the motor 506, the motor 506 drives the cam 507 to rotate. The protruding end of the rotating cam 507 hits the right end of the mounting block 501, causing the mounting block 501 to move to the left. At this time, the spring 508 deforms. When the left-moving mounting block 501 separates from the cam 507, the spring 508 returns to its original shape and drives the mounting block 501 to move to the right through the connecting rod 503, thereby making the mounting block 501 shake left and right, so that the dust attached to the electrostatic precipitator 4 falls into the dust collection box 7.

[0062] The drive assembly 5 also includes a trapezoidal slider 502 and a trapezoidal groove 6. The trapezoidal slider 502 is fixedly installed on the upper end of the mounting block 501, and the trapezoidal groove 6 is opened at the top inside the dust removal equipment housing 1. The trapezoidal slider 502 and the trapezoidal groove 6 are slidably connected in the horizontal direction.

[0063] When the mounting block 501 moves left and right, the trapezoidal slider 502 can move left and right within the trapezoidal groove 6. The trapezoidal groove 6 can guide the trapezoidal slider 502 in the horizontal direction, thereby improving the stability of the movement of the mounting block 501 and the electrostatic precipitator 4.

[0064] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
