Abstract
The utility model discloses a pump body of a waste acid concentration pump, the structure of which is one of a centrifugal type, a centrifugal mixed flow type, a mixed flow type or an axial flow mixed flow type. The pump body comprises a pump body shell, the inner side of which is embedded with a corrosion-resistant layer, the connection between the pump body shell and the corrosion-resistant layer adopts one of a gigging type, a rivet type, a screw hole type, a big-inside and small-outside groove type or a stiffener type, and the corrosion-resistant layer and the metal shell can be meshed better, thus ensuring that the corrosion-resistant layer and the metal shell are fixed together firmly and perfectly, avoiding deformation due to high temperature, cracking due to low temperature and falling-off due to negative pressure when the corrosion-resistant layer is in forced circulating state and prolonging the service life of the pump body greatly; the corrosion-resistant layer is one of a fluoroplastic layer, a glass steel layer, an enamel layer, a graphite layer or a carbon fiber layer, which can be selected arbitrarily according to the using environment and the price of the pump, thus leading the pump to have good performance price ratio. The pump body can be widely applied to the waste acid concentration pump in the industrial production processes of titanium dioxide industries, steel industries, phosphorous chemical industries, organic chemical industries and the like.
Description
Technical field
The utility model relates to the chemical pump that a kind of chemical field is carried various strongly corrosion liquids, relates in particular to a kind of pump housing of waste acid concentrating pump.
Background technique
In industrial processes such as titanium white industry, steel industry, phosphorous chemical industry, the industry that organises, all need in enormous quantities with acid, simultaneously also can produce a large amount of spent acid, these acid pump that adopts when carrying has composite steel corrosion-resistant type mixed flow pump, centrifugal pump, centrifugal mixed flow pump, axial-flow pump and axial flow mixed flow pump etc.In the spent acid callback course, generally need carry out repeatedly concentrating to spent acid, along with concentrating of spent acid, the concentration of acid also can be more and more higher. and concentrate for the first time under normal conditions, concentrate for the second time because the concentration of acid is low, temperature is below 90 ℃, adopt the pump of some metallic material, can also use reluctantly, can not make a big impact production as high silico cast iron pump, 316L, No. 20 stainless steel pumps such as alloy.But if carry out concentrating for the third time of acid, more than two class pumps just can not satisfy under this working condition and to use, because the concentration of gelled acid is 65% for the third time, 130 ℃ of temperature, there is 75% ferrous sulfate simultaneously, this is a kind of extremely abominable working condition, and under this working condition, the pump that can be suitable for is very rare, have only the pump of Hastelloy material to adapt to substantially, but promptly enable to use, its cost is also extremely expensive, and only pump maintenance cost 1 year is just up to a million, on the other hand, the difficulty of its processing is also big, and maintenance is frequent, so can not satisfy the needs that enterprise produces.
The model utility content
The utility model purpose is to provide a kind of waste acid concentrating pump pump housing of new structure, adopt novel steel lining Placement, under the prerequisite that does not influence pump intensity, prevent that effectively anti-corrosion layer from combining closely and producing negative pressure, vacuum, cracking, shelling phenomenon with pump housing shell.
The technical solution of the utility model is achieved in that
The waste acid concentrating pump pump housing, described pump body structure be centrifugal, centrifugal mixed-flow, mixed-flow or axial flow mixed-flow one of them, this pump housing comprises pump housing shell and anti-corrosion layer, it is characterized in that: described anti-corrosion layer is embedded on the described pump housing shell.
A kind of in plucking formula, rivet type, screw-hole type, interior big outer little slot type or the stiffening rib formula adopted in connection between described pump housing shell and the anti-corrosion layer.
Described anti-corrosion layer is a kind of in fluoroplastics layer, frp layer, enamel layer, graphite layer or the carbon fiber layer.
Described pump housing shell and anti-corrosion layer adopt overall structure or adopt radially or axial split composite structure.
Described pump housing shell and anti-corrosion layer are glass fibre reinforced plastic structure.
Described glass fibre reinforced plastic structure adopts overall structure or adopts radially or axial split composite structure.
Described split composite structure is a kind of in two, three or four the split composite structures.
Described pump housing shell and front pump cover are made an integral body, perhaps make an integral body with rear pump cover, perhaps make an integral body with described forward and backward pump cover.
The utility model compared with prior art has following advantage:
1. a kind of in plucking formula, rivet type, screw-hole type, interior big outer little slot type or the stiffening rib formula adopted in the connection between pump housing shell and the anti-corrosion layer.Make the interlock better of anti-corrosion layer and metal shell, can make both firmly, very ideally combine, avoid anti-corrosion layer Yin Gaowen and being out of shape not under the pump circulation state, not ftracture because of low temperature, not because of negative pressure comes off, greatly improved the working life of the pump housing.
2. anti-corrosion layer is a kind of in fluoroplastics layer, frp layer, enamel layer, graphite layer or the carbon fiber layer.Can select arbitrarily according to the Environmental Conditions of pump and the price of pump, make pump have good cost performance.
3. pump housing shell and anti-corrosion layer adopt the glass fibre reinforced plastic integral structure, improve pump housing intensity, have prolonged the working life of the pump housing.
4. pump housing shell and anti-corrosion layer are a kind of radially or in axial two, three or four the split composite structures, make things convenient for the processing of pump housing shell and anti-corrosion layer.
5. described pump housing body and front pump cover are made an integral body, perhaps make an integral body with rear pump cover, perhaps make an integral body with described forward and backward pump cover, reduce the difficulty of processing of pump, improve the bulk strength of pump simultaneously.
