Description

A kind of technics of reclaim of plastic waste dewaterer
Technical field
The present invention relates to a kind of dewaterer, refer to especially a kind of dewaterer of using for technics of reclaim of plastic waste.
Background technology
Current plastic dehydrator generally comprises base, casing, screen cloth and with the main shaft of stirring vane, casing is to be fixed on base, and the main shaft two ends are rotated by bearing block and are installed on casing, screen cloth is fixed in casing, blade on main shaft is in the screen cloth scope, on casing, an end arranges charging aperture one end discharging opening is set, and main shaft is by main shaft rotary power unit driven rotary, and the plastic foil after being broken enters into, screen cloth is interior to be driven and stirred and produce certain centrifugal force dehydration by blade.And current disintegrating machine has the following disadvantages: 1. because main shaft is directly to be rotatably installed on casing by bearing block, therefore, seal request between main shaft and casing is very high, and the main shaft High Rotation Speed, the power that casing bears is just very large, casing easily is out of shape in the junction with main shaft, and then can seal failure occur and the situation of leaking, and the reliable transmission of the rear bearing block that leaks can't guarantee, therefore, the unreasonable structure of current dewaterer, fault rate is high.2. will bear the power of main shaft rotation generation due to casing, so the rotating speed of main shaft just can not be too high, like this, the costs and poor dehydration results of material, dewatering time is long.3. the material after fragmentation may have certain residue fragment, in the process of dehydration, these residue fragments may remain on screen cloth, and the wiper mechanism of current dewaterer, the general mode that adopts washing, this mode additionally passes into clear water, has so just caused the dewatering time of this dewaterer longer.
Summary of the invention
Technical problem to be solved by this invention is: the dewaterer that provides a kind of technics of reclaim of plastic waste to use, and this dewaterer reasonable stress, the good sealing effect between main shaft and casing, compare current structure, and the speed of mainshaft of this dewaterer is higher, thus dehydrating effect is better.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of technics of reclaim of plastic waste dewaterer, comprise base, casing, screen drum and with the main shaft of stirring vane, the bottom of described casing is fixed on base, described screen drum is fixed in casing, described main shaft level is installed on the screen drum center and runs through described screen drum and casing, the two ends of described main shaft are fixed on base by bearing block, the two ends of this main shaft and the junction of casing are respectively equipped with sealing device, this main shaft drives rotation by the main shaft rotary power unit, one end of this casing is provided with the charging aperture with the screen drum internal communication, the other end of described casing is provided with the discharging opening with the screen drum internal communication, bottom of shell is provided with delivery port.
As a kind of preferred scheme, the two ends of described main shaft arrange respectively capillary groove, and each capillary groove all is arranged between sealing device and bearing block with end.
As a kind of preferred scheme, this capillary groove is spiral helicine capillary groove.
As a kind of preferred scheme, described dewaterer also comprises that this screen drum brush device for cleaning is installed on casing for cleaning the screen drum brush device for cleaning of screen drum outside with water.
As a kind of preferred scheme, described screen drum brush device for cleaning comprises the bar shaped cleaning brush that two changes and at least one and screen drum length are mated, two ends and pivot and the screen drum center superposition that is installed on casing rotated respectively in this change, the two ends of this cleaning brush are fixed between two changes, the bristle of this cleaning brush contacts with the outer peripheral face of screen drum, and this change drives rotation by the change power set.
As a kind of preferred scheme, described change power set comprise a motor, and the excircle of this change is provided with a circle external tooth, are fixed with the driving gear with the external tooth engagement on the output shaft of this motor.
As a kind of preferred scheme, described screen cloth brush device for cleaning comprises the collar be set in outside screen cloth, be fixed with circle cleaning brush radially on this collar, this cleaning brush contacts with the screen cloth outer peripheral face, and the described collar drives axial reciprocating in casing to slide by linear drive apparatus.
As a kind of preferred scheme, described linear drive apparatus comprises motor and screw-nut body, and this screw mandrel horizontally rotates to be installed in casing and by motor and drives rotation, and described nut is fixed in cover to be loaded onto.
As a kind of preferred scheme, be positioned at the discharging opening place on described main shaft and be fixed with several discharge blades.
After having adopted technique scheme, effect of the present invention is: the main shaft two ends in this dewaterer are directly by bearing block, to be installed on base, the base of casing also is fixed on base, main shaft is supported by base so, the support of main shaft is more reliable, thereby rotating speed can be higher, simultaneously, can be spaced between sealing device between casing and main shaft and bearing block, even leaking appears in sealing device, bearing block is not had to too large impact yet, and bearing block still can be guaranteed the reliable and stable work of main shaft.Like this, this dewaterer is compared with current structure, and the speed of mainshaft is higher, and the efficiency of dehydration is higher, better effects if, and fault rate is lower.
Two ends due to described main shaft arrange respectively capillary groove again; each capillary groove all is arranged between sealing device and bearing block with end; once sealing device leaks like this; water can flow along main shaft to the bearing block direction; the existence of capillary groove makes water to splash; thereby thoroughly protect bearing block, like this, the work of this dewaterer is more reliable.
Again because described dewaterer also comprises for cleaning the screen drum brush device for cleaning of screen drum outside with water, this screen drum brush device for cleaning is installed on casing, and therefore, this dewaterer changes over by original water backwashing manner the mode of cleaning with water, thereby avoid additionally introducing current, shorten dewatering time.
