Quick-mounting-type activated carbon filter

[0027] Such as Figure 1-6 As shown, the technical solution of the present invention is a quick loading activated carbon filter, which includes a rectangular cylinder 2, an air inlet 1, an air outlet 7, a number of carbon plates filled with activated carbon particles 5, a first basalt The fiber mat 3 and the second basalt fiber mat 4 are characterized in that the bottom of the cylinder 2 is provided with a sewage outlet 8 and is connected with a one-way valve 9, and the air inlet 1 and the air outlet 7 are arranged at both ends of the cylinder 2 , The air inlet 1 and the air outlet 7 are both provided with a check valve 10, the first basalt fiber mat 3, the second basalt fiber mat 4 are installed in the cylinder 2 on the side close to the air inlet 1, and the edges of the The inner wall of the body 2 is close to the inner wall of the cylinder 2, and there are two supporting frames 13 in the cylinder 2. The supporting frame 13 is close to the inner wall of the cylinder 2 and fixed around it. One of the side walls of the supporting frame 13 has a square opening. 19. The cylinder 2 is provided with a through hole 20 communicating with the square opening 19, the carbon plate 5 is in a square shape and passes through the through hole 20 into the square opening 19, and the three sides of the carbon plate 5 are attached to the inner wall of the support frame 13 By the way, the outer end of the carbon plate 5 is connected with a cover plate 11 that closes the through hole 20, and the inner side of the cover plate 11 is attached to the outer surface of the cylinder 2. The inner wall of the support frame 13 is provided with a rotatably connected sealing door 15 for sealing The rotating shaft of the door 15 is provided with a torsion spring 14 which drives the sealed door 15 to completely close the square opening 19.

[0028] The profile of the carbon plate 5 is the same as that of the through hole 20. The circumference of the carbon plate 5 is close to the wall of the through hole 20, and the sealing performance is good.

[0029] The carbon plate 5 has a square shape with a cavity inside, and the surface of the carbon plate 5 is provided with a number of pores 18 communicating with the cavity. The cavity is located at the front end of the carbon plate 5, and the pores 18 are located on both sides of the front end of the carbon plate 5.

[0030] The cover plate 11 is inserted into the outer end of the carbon plate 5 and fixed. A handle 6 is connected to the cover 11. Pull the carbon plate 5 out of the cylinder 2 by pulling the handle 6.

[0031] The bottom of the cylinder 2 is provided with supporting feet 12 for supporting. The said through hole 20 is opened on the side of the cylinder 2.

[0032] A magnetic block 16 is embedded inside the cover 11, and iron sheets 17 are embedded on both sides of the through hole 20, and the iron sheets 17 correspond to the positions of the magnetic blocks 16. The iron sheet 17 is attracted by the magnetic block 16 to fix the cover plate 11 on the cylinder 2 to prevent the carbon plate 5 from slipping out when the filter is working, causing gaseous ammonia to leak. The through hole 20 and the square opening 19 overlap each other.

[0033] The cylinder 2 of the activated carbon filter is provided with a through hole 20. The carbon plate 5 can be pulled out from the through hole 20 to replace the internal activated carbon particles. When maintenance is required, the inside can be observed at the through hole 20. The activated carbon filter It is convenient to replace the activated carbon particles and also convenient for maintenance. The activated carbon filter can also clean the inside at the through hole 20.

[0034] The activated carbon filter is used in the purification process of liquid ammonia. First, gaseous ammonia enters the cylinder 2 from the air inlet 1, passes through the first basalt fiber felt 3 and the second basalt fiber felt 4 to be filtered, and passes through two supporting boxes 13 The inner carbon plate 5 is filtered twice, and finally discharged from the air outlet 7. When the activated carbon particles in the carbon plate 5 are used for too long, the adsorption effect of the activated carbon particles will become poor, and the check valve 10 of the air inlet 1 and the air outlet 7 Close, pull out the carbon plate 5 from the through hole 20, the sealing door 15 completely closes the through hole 20, and then replace the activated carbon particles in the carbon plate 5, and then insert from the through hole 20 to make the inner wall of the cover plate 11 abut The outer surface of the cylinder 2; when maintenance is required, the check valve 10 on the air inlet 1 and the air outlet 7 of the cylinder 2 can be closed, and the gaseous ammonia inside can be evacuated, and then the carbon plate 5 can be pulled out, thereby The inside of the whole body can be inspected and repaired at the through hole 20. At the same time, water can be sprayed into the cylinder 2 at the through hole 20 for cleaning. After the cleaning is completed, the water is discharged from the sewage outlet 8, and then the carbon plate 5 is inserted back Filtration is continued at the through hole 20; the carbon plate 5 of the activated carbon filter is detachable, so that the activated carbon particles can be replaced, and the interior can be inspected and cleaned from the through hole 20 inserted into the carbon plate 5, which is highly practical.
