Embodiment Construction

[0023] The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited to the scope expressed by the examples.

[0024] according to figure 1 , figure 2 , image 3 As shown, the mold of the ultra-high pressure hydraulic pressure high-density fly ash, slag and spent catalyst module of this embodiment consists of an upper pressure module 1, an upper mold punch 2, an intermediate module 3, a lower pressure base 4, and a slider 5. Big hexagonal screw 6, small hexagonal screw 7 forms. The upper pressure-bearing module 1 and the upper die punch 2 can be fixedly connected directly by the small hexagonal screw 7, or the upper pressure-bearing module 1 that is in contact with the upper die punch 2 can be opened to match the top shape of the upper die punch 2 and the shape of the upper die punch 2. The size matches the groove, and then press the upper die punch 2 into the groove, and finall...

Abstract

The invention relates to a die for pressing hazardous waste to be a high-density module in an ultrahigh-pressure hydraulic mode. The die is composed of an upper pressure-bearing module (1), an upper die puncher pin (2), a middle module (3), a lower pressure-bearing base (4), a sliding block (5), a large hexagonal screw (6) and a small hexagonal screw (7). The upper pressure-bearing module (1) connected with a hydraulic machine is fixedly connected with the upper die puncher pin (2) through the small hexagonal screw (7). The center of the middle module (3) is provided with a vertical-through die cavity matched with the upper die puncher pin (2). The middle module (3) is fixedly connected with the lower pressure-bearing base (4) through the large hexagonal screw (6). The lower pressure-bearing base (4) is provided with a slot, and the slot corresponds to the die cavity and horizontally penetrates through the lower pressure-bearing base (4). A sliding block (5) which moves horizontally is arranged in the slot. The die can ensure that pressed material density meets requirements and facilitate die removal, can avoid corner breakage, and can be widely used for processing solid hazardous waste such as fly ash, slag and waste catalysts.

Description

technical field [0001] The invention relates to a mold for pressing solid hazardous waste into high-density modules by ultra-high pressure hydraulic pressure, in particular to a mold for pressing solid hazardous waste into high-density modules. The utility model belongs to the technical field of solid hazardous waste disposal equipment. Background technique [0002] One of the disposal methods of solid hazardous waste such as fly ash, slag, and spent catalysts is safe landfill. Among them, fly ash is produced by incineration of solid waste such as domestic garbage and urban sludge, and is neutralized and After purification, it is mixed with a certain amount of adsorbent, and then separated and collected by a high-efficiency dust separator. The main components of fly ash include SiO 2 , CaO, Al 2 o 3 , Fe 2 o 3 Reactants such as sulfate, sodium salt, potassium salt, etc., may also contain heavy metal elements such as Hg, Mn, Mg, Sn, Cd, Pb, Cr, traces of organic substan...
