The utility model relates to a
coal tar purification device. Purification structure two includes purification box no. 2, the left side of purification box no. 2 is installed with a plurality of side filter membranes, the left side of purification box no. 2 is installed with the
slag removal plate for carrying out the cleaning to the
impurity, the bottom of purification box no. 2 is installed with the connecting thin plate for guiding the
impurity, the inside of purification box no. 2 is installed with two power assemblies for cooperating with the connecting thin plate and accelerating the
impurity right movement. The utility model discloses through the
slag removal plate to the impurity cleaning on the side filter membrane, makes the impurity fall to the
slag removal
pipe in through the connecting thin plate, and through the setting of two power assemblies, accelerates the rate of the impurity to the slag removal
pipe conveying, the utility model discloses through the setting of the collection cylinder and the slag removal
pipe, makes the baffle close after the slag removal pipe, can take down the collection cylinder and remove the impurity in the collection cylinder, and then is installed below the slag removal pipe, makes purification structure two during the operation can clean the impurity, avoids the shutdown cleaning impurity and influences the impurity cleaning efficiency.
