Problems solved by technology
[0002] In the process of separating small pieces of coke and coke powder in the coking plant, the sieve hole of the drum screen is about 10mm. The coke powder in operation is relatively wet and easy to block the sieve hole. The conventional cleaning mechanism is comb-tooth type. The sieve mechanism cleans the sieve body continuously, which makes the sieve cleaning mechanism easily damaged and needs to be replaced after running for a period of time, otherwise the cleaning effect will be poor, the sieve body will be blocked, and production will be affected.

Embodiment Construction
[0018] Below in conjunction with embodiment the present invention is described in further detail:
[0019] The cleaning method of the trommel screen includes the process of cleaning the sieve body 1 by knocking the weight 2 on the sieve body 1 during the rotation of the trommel 1, and the contact between the weight 2 and the sieve body 1 during the knocking process For point contact, the wear and tear on the sieve body 1 and the weight 2 can be ignored each time, which can increase the life of the equipment; The frequency of the beating is controlled so that the sieve body 1 is knocked at least 2 times per revolution, and the sieve body 1 is knocked 3 times per revolution to make the sticky matter on the sieve body 1 be shaken off after turning from the bottom to the top. Ensure that the sieve body 1 is not blocked by adhesives and can work normally; the control method for controlling the weight 2 to hit the sieve body 1 can be an automatic method such as electric or pneumatic...

The invention discloses a screen cleaning method of a drum screen, and belongs to the field of material screening in the coking industry. The screen cleaning method comprises the process that a screen body is cleaned in the manner that the screen body is beaten by weights in the screen body rotating process of the drum screen. The screen cleaning method is characterized in that the beating frequency of the weights to the screen body is that the screen body is beaten at least two times when the screen body turns one circle. The screen body is beaten with the certain frequency to complete the screen cleaning process, abrasion of the screen body and a screen cleaning mechanism can be reduced through screen cleaning in the beating manner, and the screen cleaning effect can be best by controlling the beating frequency.
Description
technical field [0001] The invention relates to the field of material screening used in the coking industry, in particular to a method for cleaning drum sieves. Background technique [0002] In the process of separating small pieces of coke and coke powder in the coking plant, the sieve hole of the drum screen is about 10mm. The coke powder in operation is relatively wet and easy to block the sieve hole. The conventional cleaning mechanism is comb-tooth type. The sieve mechanism cleans the sieve body continuously, which makes the sieve cleaning mechanism easily damaged and needs to be replaced after a period of operation. Otherwise, the cleaning effect will be poor, the sieve body will be blocked, and production will be affected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a screen cleaning method and device with minimum wear on the screen body and the screen cleaning mechanism and better screen cleaning effe...
