Description

Technical Field

[0001] The utility model relates to the field of tar filtering, in particular to a tar filtering component which is easy to replace. Background Art

[0002] As an extremely important coal blending test equipment for quality inspection, the small coke oven often needs major repairs to ensure its normal operation due to design defects in the chemical product recovery device. Not only is the maintenance labor-intensive but also the material cost is extremely high, and the maintenance cycle is long, which seriously affects normal production needs. The conventional stainless steel filter element in the chemical product recovery device is very easy to get clogged, which makes it impossible for the pressure in the reactor to be released, and easily causes the gas hose to burst, so that the raw gas cannot be filtered and released into the room, causing the risk of poisoning to employees. When the filter element is replaced manually, the tar in the filter element is very viscous and difficult to clean, and the tar has a pungent smell and is very harmful to the human body. Every time the filter element is replaced, a large amount of accumulated tar will flow into the box and is difficult to clean.

[0003] In view of the above technical defects, a solution is now proposed. Utility Model Content

When the second electric cylinder is started, it drives the circular filter plate to move toward one end close to the exhaust gas discharge head, so that the dry quenched coke on one side of the circular filter plate below the first slot is pushed to the first slot and falls, thereby completing the discharge of the dry quenched coke in the filter tube, and then the limit rod is started again to drive the slag box to move toward the end away from the exhaust gas discharge head, so that the sliding plate closes the first slot. At this time, the stepping motor can be started again to add dry quenched coke to the filter tube again, so that the dry quenched coke used to filter tar in the device can be replaced without manual work, and a tar collection box is provided in the device to prevent the tar in the filter tube from falling into the small coke oven and being difficult to clean.

[0035] The working process and principle of the utility model are as follows:

[0036] When in use, firstly, the storage barrel 41 is filled with dry quenched coke, and then the device is connected to the gas outlet end of the small coke oven through the flange 15, and then the stepper motor 45 is started. When the stepper motor 45 is started, the extension shaft 47 and the spiral conveyor belt 48 on its outer side are driven to rotate. When the spiral conveyor belt 48 rotates, the dry quenched coke in the storage barrel 41 is fed into the filter tube 11, so that the dry quenched coke filters the tar-containing waste gas in the filter tube 11;

[0037] When the CDQ coke in the filter tube 11 is relatively saturated with tar, the first electric cylinder 25 is started to push the slag receiving box 21 to move toward the exhaust gas discharge head 20.

Then start the limit rod 26 again to drive the slag box 21 to move toward the end away from the exhaust gas discharge head 20, so that the sliding plate 22 closes the first slot 12. At this time, start the stepper motor 45 again to add the dry quenched coke to the filter tube 11 again.
