Embodiment 1

[0016] Example 1: Taking the copper concentrate ore slurry of Dexing Copper Mine as an example, in the beneficiation, gold, molybdenum, sulfur, and finally copper beneficiation are carried out. # (foaming agent), MAC-12, xanthate, butyl xanthate, lime, sodium sulfide, six sodium phosphate tablets. It is the addition of these beneficiation agents, and the particle size of the pulp is -400 mesh, accounting for 70%, which makes the ceramic filter plate prone to chemical scaling and mechanical blockage. The service life (blocking cycle) of the ceramic filter plate before cleaning is less than 6 months, and the average processing capacity of the ceramic filter in use is 248.3Kg / m 2 h. After the filter plate is cleaned with the cleaning agent of the present invention according to the above method, the processing capacity of the ceramic filter in use increases to 452.6Kg / m 2 h, the service life of the ceramic filter plate is extended to 13 months, the processing capacity of the fil...

Embodiment 2

[0017] Example 2: Taking the sulfur concentrate ore slurry of Yinshan Mining Company as an example, in the beneficiation, through lead, zinc, copper and finally sulfur beneficiation, the beneficiation agents added in the beneficiation are 111 # (foaming agent), lime, xanthate, thiamine, MOS # , MA-1 # . It is the addition of these beneficiation agents, and the particle size of the pulp is -300 mesh, accounting for 80%, so that the service life (blocking cycle) of the ceramic filter plate before cleaning is 10 months, and the average processing capacity of the ceramic filter in use is 365.3 Kg / m 2 h. After the filter plate is cleaned with the cleaning agent of the present invention according to the above method, the processing capacity of the ceramic filter in use increases to 616.7Kg / m 2 h, the service life of the ceramic filter plate is extended to 18 months, the processing capacity of the filter is increased by 68.8%, and the service life of the ceramic filter plate is i...

Embodiment 3

[0018] Embodiment 3: Take Huaibei Jinsheng iron concentrate slurry as an example, in the beneficiation process, the ore mainly comes from Anqing Copper Mine, first copper beneficiation, add beneficiation agent xanthate, pine oil; then select iron desulfurization, add beneficiation agent sulfuric acid , to get magnetite. Finally, the pyrite slurry and hematite slurry from Anqing Copper Mine and other mines are filtered with ceramic filter in Huaibei Jinsheng Concentrator, and the slurry particle size is -400 mesh, accounting for 70%. In the filtration, the service life (blocking cycle) of the ceramic filter plate before cleaning is 8 months, and the average processing capacity of the ceramic filter in use is 350.9Kg / m 2 h. After the filter plate is cleaned with the cleaning agent of the present invention according to the above method, the processing capacity of the ceramic filter in use increases to 632.6Kg / m 2 h, the service life of the ceramic filter plate is extended to 18...

Abstract

This invention relates to a washing agent used in rinsing ceramic strainer plate. According to the weight percentage, it contains the following materials: nitric acid 0.1~5%; hydrochloric acid 0.1~5%; hydrofluoric acid 0.2~3%; oxalic acid 0.1~5%. By the combined action of nitric acid, hydrochloric acid and hydrofluoric acid, it can deal with the mixed dirt such as carbonate, silicate, sulphate, phosphate, sulphide and hydroxid, and so on. The washing effectiveness is good and the scope of application is extensive. Otherwise, it can enhance the operating life of strainer plate and can extend the serviceable range of ceramic filtering machine.

Description

Technical field [0001] The invention relates to a cleaning agent for cleaning a ceramic filter plate on a ceramic filter. Background technique [0002] The ceramic filter is a solid-liquid separation equipment designed by using the capillary principle of ceramic micropores -- water permeable and airtight. The size of ceramic micropores is generally 0.1 ~ 10um. During production and use, the filter cake is adsorbed on the surface of the ceramic filter plate, and the filtrate is sucked away through the micropores of the ceramic filter plate. The reciprocating cycle of such a process inevitably forms chemical scaling and mechanical blockage (deposition of particles and slime) in the micropores. Although the equipment is designed with nitric acid cleaning, ultrasonic cleaning and water backwashing devices, and every 8 It is used once every 10 hours, but for different filtering objects, the problem of clogging still often occurs, ranging from less than a month to less than a yea...
