Description

The reducing mechanism of sulfuration sodium raw materials pretreatment stage

Technical field

This utility model is related to the processing equipment of raw material before the production of sodium sulfide.

Background technology

Sodium sulfide is also known as smelly alkali, smelly soda, yellow alkali, akali sulphide.Sodium sulfide is inorganic compound, and pure sodium sulfide is colourless knot

Crystalline flour end；Moisture absorption is strong, soluble in water；Aqueous solution is reacted in strong basicity；Can cause to burn when touching skin and hair Wound；Therefore sulfur

Change sodium and be commonly called as akali sulphide.

Domestic production sodium sulfide mainly has following several method at present：1. coal reduction mirabilite method；2. sodium hydroxide is inhaled Receive hydrogen sulfide method；3. sodium sulfate and barium sulfide double decomposition；4. hydrogen reducing sodium sulphate method.Although absorption process power consumption and There are absolute advantagess in terms of CO2 discharge capacitys, but raw material sources are limited, can only be given birth to as the side-product of related chemical enterprise Produce, it is difficult to meet demand of the industrial development to sodium sulfide；The same raw material of barium sulfate method is very limited；Gas reduction method can So that high-quality sodium sulfide is obtained, but its production cost is high, not dominant in energy consumption and carbon emission；Coal reduction method produces sodium sulfide Low cost, raw material sources extensively, can be produced in a large number, but resource utilization is relatively low, and energy consumption is also higher.Therefore, big at present Most enterprises still produce sodium sulfide using coal reduction method.

The mode of operation of existing coal reduction method is by 100 by Natrii Sulfas and coal dust：21～22.5（Weight ratio）Proportioning Mixed

Close, calcining reduction under 800～1100 DEG C of high temperature, product is after cooling with sig water thermosol into liquid, quiet After putting clarification,

Top high alkali liquid is concentrated, solid sodium sulfide is obtained final product, through transfer tank, film-making（Or pelletize）Prepared piece（Or grain） Shape sodium sulfide product.But existing production method has the disadvantage that：First, the relatively costly of coal dust is directly bought；2nd, existing It is only to be simply mixed that Natrii Sulfas are mixed with coal dust, and Natrii Sulfas are usually irregular lamellar or granule, are simply mixed, its contact area Little, therefore, during heating reduction, easily cause Natrii Sulfas, coal dust and react imperfect, coal dust calcining not exclusively, produces substantial amounts of waste gas, and The sodium sulfide for producing is caused to yield poorly.

Thus, for example No. 2669757 publication of 1 patent of patent documentation discloses such a pulverizer：It is being close to casing The outer peripheral face of the crushing cutlery rotated by internal face, offers insertion and crushes internal face direction jet compression of the cutlery to casing The spray-hole of air, forms the compressed air path for supplying compressed air to spray-hole in the rotary shaft for crushing cutlery, thus, The rotation of crushing cutlery can be made from the periphery for crushing cutlery while the internal face jet compression air to casing Face jet compression air, so as to remove the residue remained in pulverizer at short notice.

Content of the invention

This utility model provides a kind of reducing mechanism of sulfuration sodium raw materials pretreatment stage, can safely and reliably by sulfuration Sodium raw materials are crushed, and working place requires little, to be conducive to holding to clean working environment, and the muscle power for reducing operator is paid Go out.

A kind of reducing mechanism of sulfuration sodium raw materials pretreatment stage, support feet are fixed on ground, and table top is fixed on support The upper end of foot, upper layer bracket are then installed based on support feet, between the table top and upper layer bracket be broken motor, Decelerator and drainage conduit, the drainage conduit through stretching into inside finished product hopper after table top, decelerator and broken motor connection, The outfan of decelerator then directly drives corner block rotation, then installs attrition crushing mechanism on three faces of the corner block, squeezes Pressure crushing mechanism is collectively forming extruding space with broken material tube inner wall, and broken barrel is then fixed on the centre position of upper layer bracket.

The attrition crushing mechanism includes roller motor, chute support body, Positioning screw and compression roller and broken wheel, Chute support body is fixed on the side of corner block, and the side of compression roller is hinged with corner block, and opposite side is in the chute of chute support body Slide, and fixed by Positioning screw after determining good position, the top surface of the compression roller installs roller motor, roller Motor drives broken wheel rotation.

The drainage conduit is crescent, and upper end is connected with the bottom surface of broken barrel, and the outside wall surface near broken barrel Fixed.

Remarkable result of the present utility model is：

1st, this utility model is the crushing mechanism of an easy sodium sulfide raw material pulverizing and mixing, and system structure simply, can High by property, while machined piece regular shape, the optional standard component of most components, it is possible to decrease cost and shortening production cycle.

2nd, the advantage for especially projecting is that this device is provided between two-stage crushing function, and two-stage function and also there is phase mutual coupling Close, the rotation of broken wheel and revolve round the sun and deposit, at the same combination of extrusion roller in the presence of centrifugal load to crushing the raw material inside barrel Attrition crushing is carried out, course of action is smoothed out, and reduces the degree of participation of personnel.

3rd, the position of attrition crushing mechanism is adjustable, so as to change the distance between compression roller and broken wheel and broken barrel, And then the granularity of change powder, be conducive to the scope of application for improving this device.
