Description

Technical Field

[0001] The present application relates to the technical field of ceramic tube dust removal, and in particular, to a ceramic tube dust removal device. Background Art

[0002] Ceramic tube dust collector is a cyclone type dust collector. When the dust-laden gas enters the dust collector, it passes through the ceramic guide and rotates at high speed inside the cyclone. Under the action of centrifugal force, the dust and gas are separated, and the dust falls into the dust collecting box and is discharged through the ash discharge valve. The purified gas forms an ascending vortex, which is collected in the gas collecting chamber through the exhaust pipe and discharged from the chimney through the outlet to achieve the dust removal effect.

[0003] In order to prevent the filtered gas from mixing with the exhaust gas again, the top of the ceramic tube needs to be sealed. In the prior art, a sealing gasket is installed on each ceramic tube (for example, the application announcement number is: CN205649953U, and the name is: A porous ceramic tube installation and fixing device for a dust collector). Although this device can achieve a good sealing effect, it needs to be installed one by one, which makes the production cumbersome. In the prior art, there is also a method of installing a whole sealing gasket on top of all ceramic tubes for sealing. However, since each ceramic tube is not completely flush, the sealing gasket cannot be completely fitted with each ceramic tube in actual application, so the sealing effect is poor.

[0028] like Figure 1 and Figure 3 As shown, the embodiment relates to a ceramic tube dust removal device, the ceramic tube dust removal device is connected to the exhaust gas pipeline, and the ceramic tube dust removal device includes: a dust removal chamber 10 and a filter assembly 20. The dust removal chamber 10 has a accommodating space. The filter assembly 20 is arranged in the dust removal chamber 10, and the filter assembly 20 includes a pressing plate 21, a ceramic tube 22 and a fixing structure 23, the pressing plate 21 is arranged above the ceramic tube 22, the fixing structure 23 and the ceramic tube 22 are arranged correspondingly, and the fixing structure 23 includes an elastic member 231, and the elastic member 231 is arranged below the pressing plate 21.

[0029] The technical solution of this embodiment is applied, the dust removal device is connected with the exhaust gas pipeline, the filter assembly 20 includes a pressing plate 21, a ceramic tube 22 and a fixed structure 23, the filter assembly 20 is arranged in the dust removal chamber 10, the exhaust gas enters the ceramic tube 22 from the dust removal chamber 10 and is filtered, and the filtered gas is discharged from the inside of the ceramic tube 22, the pressing plate 21 is arranged above the ceramic tube 22 and can seal the ceramic tube 22 to prevent the exhaust gas from overflowing and mixing with the filtered gas, the fixed structure 23 and the ceramic tube 22 are arranged correspondingly, and the fixed structure 23 and the pressing plate 21 work together to fix and seal the ceramic tube 22, the fixed structure 23 includes an elastic member 231, the elastic member 231 is arranged below the pressing plate 21, the elastic member 231 can be elastically deformed, and can have good adaptability to the pressure of the pressing plate 21, which makes the pressing plate 21 and the ceramic tube 22 fit more closely and the sealing effect is better. The technical solution of this embodiment effectively solves the problem of poor sealing effect of the ceramic tube 22 in the prior art.

[0030] like Figure 4As shown, in some embodiments, the fixed structure 23 further includes a first fixed cover 232 and a second fixed cover 233, the elastic member 231 is arranged between the first fixed cover 232 and the second fixed cover 233, the first end of the elastic member 231 is connected to the first fixed cover 232, and the second end of the elastic member 231 is connected to the second fixed cover 233. The elastic member 231 is a spring, and the elastic member 231 is connected to the first fixed cover 232 and the second fixed cover 233 by welding. The ceramic tube 22 has a plurality of fixed structures 23, and the plurality of fixed structures 23 and the plurality of ceramic tubes 22 are arranged one by one. The first fixed cover 232, the second fixed cover 233 and the elastic member 231 are all arranged on the circumferential outer side of the ceramic tube 22, the first fixed cover 232 and the second fixed cover 233 have an annular surface, and the elastic member 231 has a plurality of elastic members, and the plurality of elastic members 231 are arranged circumferentially along the annular surface of the first fixed cover 232 and the second fixed cover 233.

[0031] like Figure 2 As shown, in some embodiments, the filter assembly 20 further includes a support structure 24, the support structure 24 includes a support plate 241 and a fixing plate 242, the fixing plate 242 is arranged on the circumferential outer side of the support plate 241, the fixing plate 242 is connected to the inner wall of the dust removal chamber 10, the support plate 241 has a first matching hole, and the ceramic tube 22 is inserted into the first matching hole. There are multiple first matching holes, and the multiple first matching holes and the multiple ceramic tubes 22 are arranged one by one. The diameter of the first matching hole is larger than the diameter of the ceramic tube 22. When the exhaust gas temperature is high, it can prevent the support plate 241 that expands due to heat from causing the ceramic tube 22 to rupture.

[0032] like Figure 2 and Figure 5As shown, in some embodiments, the fixing structure 23 further includes a first pad 234, which is arranged between the pressing plate 21 and the second fixing cover 233. The ceramic tube 22 has a first tube section 221 and a second tube section 222, the diameter of the first tube section 221 is greater than the diameter of the second tube section 222, the first tube section 221 is located between the pressing plate 21 and the first pad 234, and abuts against the first pad 234, and the second tube section 222 passes through the first pad 234, the second fixing cover 233, the first fixing cover 232 and the first matching hole respectively. The material of the first pad 234 is rubber material, which can prevent the second fixing cover 233 from causing adverse effects on the ceramic tube, and the fixing structure 23 further includes a second pad, which has a plurality of second pads, and the plurality of second pads are arranged corresponding to the plurality of ceramic tubes 22, and the second pad is arranged between the pressing plate 21 and the first tube section 221 to prevent the pressing plate from causing adverse effects on the ceramic tube 22. The second pad is made of rubber. The diameters of the first pad 234, the second fixed cover 233, the first fixed cover 232 and the first matching hole are all larger than the diameter of the second pipe section 222, and smaller than the diameter of the first pipe section 221. This setting is to prevent the ceramic tube 22 from breaking when it expands at high temperature, affecting the filtering effect. At the same time, the first pipe section 221 can abut against the second pad, thereby supporting the ceramic tube 22. The second fixed cover 233 and the support plate 241 abut against each other, and the support plate 241 supports the second fixed cover 233, thereby supporting the elastic member 231, the first fixed cover 232, the first pad 234, the first pipe section 221 and the second pad. During the matching process between the ceramic tube 22 and the fixed structure 23, different ceramic tubes 22 will have height differences. The elongation and expansion of the elastic member 231 enable each second pad to fit tightly with the pressing plate 21 to achieve a good seal.

[0033] like Figure 2 As shown, in some embodiments, the pressing plate 21 can be in direct contact with the first pipe section 221, and the elastic member 231 corresponding to the different ceramic tubes 22 can make the pressing plate 21 and the first pipe section 221 fit tightly to achieve good sealing. The first pipe section 221 has an inner diameter and an outer diameter, the outer diameter is larger than the inner diameter, and the filtered gas flows out from the ceramic tube 22 (corresponding to the inner diameter). The pressing plate 21 has a second matching hole 211, and the diameter of the second matching hole 211 is between the inner diameter and the outer diameter. This arrangement enables the pressing plate 21 to be against the first pipe section 221, and exert a downward force on the ceramic tube 22. The support plate 241 exerts an upward force on the fixing structure 23, and the fixing structure 23 exerts an upward force on the ceramic tube 22, thereby achieving a fixing effect on the ceramic tube. At the same time, since the diameter of the second matching hole 211 is larger than the inner diameter, it will not affect the discharge of the gas, and the diameter of the second matching hole 211 is smaller than the outer diameter, it can play a sealing role.

[0034] In some embodiments, the second pipe segment 222 is spaced apart from the first pad 234, the second fixing cover 233, the first fixing cover 232 and the first matching hole. This arrangement is intended to prevent the first pad 234, the second fixing cover 233, the first fixing cover 232 and the support plate 241 from expanding due to heat under the influence of high-temperature exhaust gas, causing the second pipe segment 222 to rupture and affecting the filtering effect.

[0035] like Figure 2 and Figure 4 As shown, in some embodiments, the fixing structure 23 further includes a first screw 235, the first fixing cover 232 has a first through hole, the support plate 241 has a first threaded hole, and the first screw 235 passes through the first through hole and matches with the first threaded hole. The first fixing cover 232 has a plurality of first through holes, and the first screw 235 has a plurality of first screws, and the plurality of first screws 235 are arranged one-to-one with the first through holes. The first screw 235 is tightened with the first threaded hole through threaded matching, and the first fixing cover 232 is connected to the support plate 241, so that the ceramic tube 22 is better fixed.

[0036] like Figure 2 As shown, in some embodiments, a threaded column 2421 is provided on the fixing plate 242, and the threaded column 2421 is oriented in a direction close to the support plate 241. The fixing structure 23 also includes a second screw 236. The pressing plate 21 has a second through hole. The second screw 236 passes through the second through hole and cooperates with the threaded column 2421. The threaded column 2421 is arranged on the inner side of the fixing plate 242. The pressing plate 21 and the fixing plate 242 are fixed together by the thread cooperation of the second screw 236 and the threaded column 2421. The threaded column 2421 is arranged at the four corners of the fixing plate 242, which makes the fixation more firm. The circumferential outer side of the pressing plate 21 and the circumferential inner side of the fixing plate 242 fit together, which enables the pressing plate 21 to effectively prevent the exhaust gas from overflowing from the gap between the ceramic tube 22 and the fixing structure 23, and can effectively enhance the sealing performance.

[0037] In some embodiments, a plurality of threaded columns 2421 can be fixedly connected to the support plate 241, and the threaded columns 2421 are arranged in an array. The threaded columns 2421 are located in the gaps between the ceramic tubes 22, and a plurality of second through holes are arranged at positions corresponding to the threaded columns 2421 on the pressing plate 21. The second screws 236 pass through the second through holes and cooperate with the threaded columns 2421. This makes the fixing of the pressing plate 21 more secure, and at the same time, the pressing plate 21 and the second pad are more closely fitted, so the sealing effect is better.

[0038] like Figure 1As shown, in some embodiments, there are multiple ceramic tubes 22, which are arranged in an array, and adjacent ceramic tubes 22 are spaced apart, and the support structure 24 further includes a reinforcing plate 243, and there are multiple reinforcing plates 243, and the multiple reinforcing plates 243 are all arranged below the support plate 241, and the reinforcing plates 243 are located between adjacent ceramic tubes 22 and connected to the inner wall of the dust removal chamber 10. The reinforcing plates 243 can play an auxiliary supporting role for the support plate 241 to prevent the support plate 241 from being deformed.
