Abstract
The utility model discloses a ceramic screw pump, which is suitable for conveying sand pulp, ore pulp, corrosive medium fluid and high concentration granular materials. The utility model is composed of a material bin (5), a spiral type feeding device (4) arranged in the material bin (5), a ceramics screw (1), a stator matched with the screw (1), and a pump body (3), the ceramic screw (1) is the composite structure of a steel core shaft and a ceramic screw sleeve which has a spiral face and is sheathed out of the steel core shaft. The utility model has the advantages of abrasion resistance, corrosion resistance, low running cost, etc., and provides new equipment to conveying of special materials.
Description
The utility model relates to a kind of high concentration conveyor worm pump.This screw pump is used for high concentrations such as mortar, ore pulp, Korrosionsmedium or has the conveying of granular material.
Screw pump is a kind of rotary displacement self-priming pump, and main working parts is made up of eccentric screw and stator.This pump carries and contains the conveying of solid particle medium, the characteristics that have general pump not replace to high viscosity fluid." mechanical engineering manual " the 77th piece of P67～P80 that China Machine Press publishes March nineteen eighty-two introduced this screw pump.At present, screw pump has been widely used in fields such as food, papermaking, electric power, chemical industry, oil, metallurgy, building.But in use find core component screw rod wearing and tearing easily in the screw pump operation process of screw pump, special at high concentration mortar, ore pulp, Korrosionsmedium or when having the conveying of granular material, the easier screw rod that causes weares and teares, thereby influences the efficient and the cost of screw pump.At present, screw pump adopts carbon steel, stainless steel or chromium plating screw rod when carrying general medium.For high concentration mortar, ore pulp, Korrosionsmedium or have materials such as adopting carbonitriding, ni-hard cast iron, rich chromium cast iron, Ni based spray-welded when particle media is carried once and processing technology is made various screw rods tests.These methods have certain wear-resisting, anti-corrosion effects according to the medium difference, but effect is all not ideal enough, and the processing technology complexity, cost is higher, quality is unstable.
The purpose of the utility model pottery screw pump is exactly for solving the above-mentioned problems in the prior art, and provides a kind of wear-resistant, anticorrosive, and manufacturing process is simple, steady quality, cost are low, the ceramic screw pump of long service life.
In order to achieve the above object, the utility model pottery screw pump is by the following technical solutions:
The utility model pottery screw pump by feed bin, be located at the helixes feed equipment in the feed bin, ceramic screw rod, the stator and the pump housing that are complementary with ceramic screw rod form, ceramic screw rod is connected with the running shaft of spiral feeding device.The pottery screw rod is a composite structure, and central authorities are the steel core axle, the compound cover of coated outside helicoid pottery screw rod of steel core axle, and each pitch of ceramic screw rod is a ceramic screw rod cover.
The cross sections shape of above-mentioned steel core axle can adopt the alternate face that forms with straight line of circular arc, can prevent relatively rotating of steel core axle and ceramic screw rod cover like this.
Compared with prior art, following advantage is arranged after the utility model pottery screw pump employing technique scheme:
1, adopt the composite structural ceramic screw rod, the skin of screw rod is an engineering ceramics, and the screw pump wear-resisting property is improved a lot, and helps screw pump at high concentration mortar, ore pulp medium or have application in the particle media.Prolong the working life of screw pump, reduce operating cost.
2, adopt the composite ceramics screw rod, the ceramic screw rod after the moulding need not carry out machining, and the manufacture cost of screw rod is significantly reduced, and quality, physical dimension are easy to control.
3, adopt engineering ceramics manufacturing pottery screw rod to make screw pump have performances such as high temperature resistant, anticorrosive, help screw pump and under high temperature, strong acid-base environmental conditions, work.
4, engineering ceramics is nonmetal, can utilize ceramic screw pump for the medium (as inflammable and explosive material) that is unsuitable for metal screw pump is carried, and has enlarged the using scope of screw pump.
For further describing the utility model, be described in more detail below in conjunction with drawings and Examples the utility model pottery screw pump.
Fig. 1 is the utility model pottery screw pump structural representation.
Fig. 2 is the ceramic screw-rod structure schematic representation of the utility model pottery screw pump.
Fig. 3 be among Fig. 2 along A-A to sectional view.
By the utility model shown in Figure 1 pottery screw pump structural representation as can be seen, the utility model pottery screw pump is by feed bin 5, and the stator 2, the pump housing 3 that be located at spiral feeding device 4 in the feed bin 5, ceramic screw rod 1, are complementary with ceramic screw rod 1 are formed.Spiral feeding device 4 is to be made of the helical blade on running shaft, the dried running shaft of installation, and ceramic screw rod 1 is same axis with the running shaft of feeding device 4.Stator 2 adopts elastomer stator.
In conjunction with Fig. 1 and as can be seen by the ceramic screw-rod structure schematic representation of the utility model shown in Figure 2 pottery screw pump, the central authorities of pottery screw rod 1 are steel core axle 6, at steel core axle 6 coated outside helicoids pottery screw rod cover 7, each pitch of ceramic screw rod 1 is the ceramic screw rod cover of a joint.Steel core axle 6 and one group pottery screw rod cover 7 is assembled and is bondd, and finally forms a complete composite structural ceramic screw rod 1.
A-A by Fig. 2 shown in Figure 3 finds out that to sectional view the cross section of steel core axle 6 adopts three circular arcs and three faces that straight line is alternately formed mutually, can avoid relatively rotating between steel core axle 6 and the ceramic screw rod cover 7 like this.
The utility model pottery screw pump is in the conveying material process, material enters feed bin 5, in feeding device 4 was inhaled into the cavity of ceramic screw rod 1 and elastomer stator 2, along with the rotation of ceramic screw rod 1, ceramic screw rod 1 and elastomer stator 2 volume-variation that contacts cavity that is meshing with each other was come conveying material.When the potted line of ceramic screw pump suction chamber one end continuously when discharge side one end moves axially, the suction chamber volume is increased, pressure reduces, material enters suction chamber at differential pressure action lower edge material feeding mouth.Along with the rotation of ceramic screw rod 1, the material in the Seal cage moves to discharge side continuously and equably vertically.Because the discharge side volume dwindles gradually, then produces pressure, the material extruding is advanced.Because the material sectional area that moves is a constant,, form the no pulse steady flow so the material travelling speed also is a constant in elastomer stator 2.
Claims (2)
1, a kind of ceramic screw pump, by feed bin (5), the stator (2) and the pump housing (3) being located at spiral feeding device (4) in the feed bin (5), ceramic screw rod (1), being complementary with ceramic screw rod (1) are formed, pottery screw rod (1) is connected with the running shaft of spiral feeding device (4), it is characterized in that: described ceramic screw rod (1) is steel core axle (6), is wrapped in helicoid pottery screw rod cover (7) composite structure of steel core axle (6) outside that each pitch of ceramic screw rod (1) is a ceramic screw rod cover.
