Abstract
A spiral dewatering device with an adjustable screw pitch comprises a box body and a rotary shaft arranged inside the box body. A netted dewatering net is arranged between the rotary shaft and the box body. The spiral dewatering device is characterized in that at least two spirals are arranged on the rotary shaft; the heads and the tails of the adjacent spirals are overlapped and connected; one spiral overlapped portion is fixedly connected with the rotary shaft; another spiral overlapped portion is disconnected with the rotary shaft; at least two threaded holes in up and down arrangement are arranged on one of the two spiral overlapped portions; and bolts are screwed into threads. By dividing one original spiral into a plurality of adjustable spirals with mutually connected heads and tails, the spiral dewatering device enables the spirals to be more reasonable in dewatering structure and better in dewatering effect, and can adjust the screw pitch according to actual conditions of wheat straw pulp, thereby changing dewatering effect.
Description
Technical field
The utility model belongs to a kind of physics method paper making equipment, a kind of specifically spiral dewater unit.
Background technology
In the process that the mechanical approach Straw Pulp is produced, need carry out processed to the wheat straw of softening and moistening mistake.Existing spiral dehydrated structure all is the pitch grading structure that do not wait of a pitch of reserving in advance or the structure of rotating shaft Diameter Gradual Change, is used for realizing the dehydration of wheat straw by the mutual extrusion of Straw Pulp and spiral.The helical axis of announcing as Chinese patent 99221399.1, the gradual change of the Diameter Gradual Change control cavity by the axial two ends of helical axis realizes the dehydration of wheat straw exactly.The problem that this spiral dehydrated structure exists is, because the pitch of spiral is non-adjustable, makes that the different Straw Pulp dehydrating effect when dewatering of water content is inconsistent, directly influenced next step wheat straw decomposition technique.
The utility model content
In order to solve the deficiencies in the prior art, the utility model provides a kind of pitch adjustable spiral dewater unit, by extruding dirty hot water, leachable in the wheat straw is broken away from, and dehydrating effect is controlled.
The technical scheme that its technical problem that solves the utility model adopts is: this kind spiral dewater unit, comprise that a casing and is arranged on the rotating shaft in the casing, netted draining net is set between described rotating shaft and the casing, it is characterized in that, two sections spirals are set in the described rotating shaft at least, adjacent spiral overlapping joining of head and the tail, one of them spiral lap is fixedlyed connected with rotating shaft, another spiral lap and rotating shaft disconnect, and be provided with two screwed holes of arranging up and down on one of them at least, screw bolt in the screw thread.
Described bolt is a stud, the non-bolt head.
The length of described spiral overlapping is at least 2/3rds of rotating shaft girth.
The beneficial effects of the utility model are: the utility model is by being divided into several end to end adjustable spirals with an original spiral, make that this spiral dehydrated structure is more reasonable, dehydrating effect is better, and can regulate pitch, and then change dehydrating effect according to the actual conditions of Straw Pulp.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 launches schematic diagram for the spiral lap;
Fig. 3 is the sectional drawing of Fig. 2.
Among the figure: 1 first spiral, 2 second spirals, 3 triple helicals, 4 rotating shafts, 5 bolts.
The specific embodiment
As Fig. 1, this kind spiral dewater unit, become certain included angle with horizontal plane, comprise a casing and a rotating shaft, the upper end of casing is a discharging opening, and the lower end is a charging aperture, the rotating shaft that the box house setting can rotate freely, netted draining net is set between described rotating shaft and the casing, and the lower position of described casing sets out the mouth of a river.
Three sections spirals are set in the described rotating shaft, i.e. first spiral 1, second spiral, 2, the triple helicals 3, described spiral adjacent overlapping joining of head and the tail, first spiral, 1 one end laps are fixedlyed connected with rotating shaft 4, second spiral, 2 one end laps and rotating shaft 4 disconnect, and are in free state, and on one of them screwed hole are arranged, screw bolt 5 in the screw thread, by regulating the pitch that bolt 5 can be regulated second spiral, 2 overlay segments.In like manner, second spiral, 2 other end laps are fixedlyed connected with rotating shaft, and triple helical 3 one end laps and rotating shaft 4 disconnect, be in free state, and on one of them screwed hole arranged, for guaranteeing the intensity of spiral, can arrange two or more bolts up and down, screw bolt in the screw thread.By regulating the pitch that bolt can adjustable screw, thereby can effectively regulate the extrusion dehydration effect.For ease of used bolt is installed is stud, and the non-bolt head is avoided bridging.
Adjustment process is: when the draining of Straw Pulp is good, reduce the pitch of overlay segment, when the draining difference of Straw Pulp, increase the pitch of overlay segment by bolt.For guaranteeing the draining effect, the length of described spiral coincidence place is at least 2/3rds of rotating shaft girth.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (3)
1. spiral dewater unit, comprise that a casing and is arranged on the rotating shaft in the casing, netted draining net is set between described rotating shaft and the casing, it is characterized in that, two sections spirals are set in the described rotating shaft at least, adjacent spiral overlapping joining of head and the tail, one of them spiral lap is fixedlyed connected with rotating shaft, another spiral lap and rotating shaft disconnect, and are provided with two screwed holes of arranging up and down on one of them at least, screw bolt in the screw thread.
2. spiral dewater unit according to claim 1 is characterized in that, described bolt is a stud, the non-bolt head.
