Embodiment 1

[0031] like figure 1 It shows, a acid -alkaline -resistant mixing dryer, including a tube cover 2 on the upper end of the cylinder cylinder, the inlet of the feed inlet on one side of the tube cover 2, and the pump on the other side above the tube cover 2Qi Device 4, a stirring device 5 in the middle of the tube cover 2, the inner wall of the cylinder 1 is provided with a layer of sliding wear -resistant layer 6, and several U -shaped grooves 7 in the outer wall of the tube cylinder 1.There is a cylindrical body 8 on the outside of the cylinder, and a purse port 9 is provided with the lower end of the cylinder 1. There is also a thermal insulation layer 10 between the cylinder 8 and the cylinder 1.Groove; the thickness of the cylinder 1 is 1-5mm (the best thickness is 3mm, of course, you can also choose 1mm or 5mm), the depth of the U-shaped groove 7 of the outer wall of the cylindrical cylinder 10.8mm, according to the thickness of the cylinder 1, you can also choose 0.5mm or 1mm)....

Embodiment 2

[0041] The embodiment is the same as the embodiment. The difference is that the components of the acid -alkali -resistant stainless steel are calculated based on the weight percentage (the following%indicate the weight percentage): 0.17%, nickel is 7%, chromium is 9 to 9%, Manganese is 11%, 0 is 0.58 %%, 钒 0.32%, molybdenum is 1.8%, titanium is 4%, rare earth is 0.53%, the total amount of phosphorus and sulfur does not exceed 0.035%.Unavoidable impurities, the preparation process of acid -alkali -resistant stainless steel includes the following steps:

[0042] Step 1. Use the medium -frequency induction electric furnace to melt. The sequence of metal furnaces is the order of raw iron, scrap steel, molybdenum, nickel iron, manganese iron, chromium iron, and the felting temperature is 1610 ° C.After that, the molybdenum, iron, titanium iron, and iron iron are added. At the end of the melting, the rare earth is added to make the alloy composition in the steel reaches the predetermine...

Embodiment 3

[0047] The embodiment is the same as the embodiment 1 and the embodiment two. The difference is that the components of the acid -alkali stainless steel are calculated at the weight percentage (the following%indicate the weight percentage), Chromium is 10%, manganese is 9.5%, 铌 is 0.65%, 钒 0.27%, molybdenum is 1.5%, titanium is 3.7%, rare earth is 0.46%, the total amount of phosphorus and sulfur does not exceed 0.035%, and the remaining amount is to be the amount.The unavoidable impurities of iron, the preparation process of acid -alkali -resistant stainless steel includes the following steps:

[0048] Step 1. Use the medium -frequency induction electric furnace to melt. The sequence of metal furnaces is the order of raw iron, scrap steel, molybdenum, nickel iron, manganese iron, chromium iron, and the felting temperature is 1610 ° C.After that, the molybdenum, iron, titanium iron, and iron iron are added. At the end of the melting, the rare earth is added to make the alloy composi...

Abstract

The invention discloses an acid- and alkali-resistant stirring drier. The acid- and alkali-resistant stirring drier comprises a barrel cover which is arranged at the upper end of a barrel cylinder, a feeding port which is formed in one upper side of the barrel cover, an air exhausting device which is arranged at the other upper side of the barrel cover, and a stirring device which is arranged in the upper middle of the barrel cover, wherein a slipping-aiding wear-resisting layer is arranged on the inner wall of the barrel cylinder; a plurality of U-shaped grooves are excavated in the outer wall of the barrel cylinder; a barrel body is arranged at the outer part of the barrel cylinder, and a discharging port is formed in the lower end of the barrel cylinder; a heat insulation layer is also arranged between the barrel body and the barrel cylinder, and a vertical slot is formed in the surface of the heat insulation layer. With the adoption of the acid- and alkali-resistant stirring drier, the problem of low efficiency of the drier in the heat exchanging process can be solved, and the damage caused by that the inside of the drier is affected with damp can be removed; meanwhile, a material for the barrel cylinder is also provided, thus various comprehensive performances of the barrel cylinder are improved, and the service life is prolonged.

Description

Technical field [0001] The present invention involves a drying equipment field, and it specially involves a acid -alkaline -resistant stirring dryer. Background technique [0002] Vacuum dryers are designed for drying thermal sensitivity, easy decomposition and oxidative substances, and can fill the inert gas to the interior, especially some items with complex components can also be quickly dry.The vacuum dryer is designed by removing the internal part of the container by pumping the internal air in the packaging container, which is designed for dry thermal sensitivity, easy decomposition and oxidative substances.Complex items can also be dried quickly. [0003] In the existing vacuum stirring dryer, there is a defect in heating and heat exchange, that is, when steam is passed into the dryer, the heat of the steam is not fully utilized. When changing the heat in the cylinder, the heat exchange time is short.The heat exchange is uneven, and a large amount of steam is discharged fr...
