Detailed Description
The technical solution of the present invention is further described and illustrated by the following specific embodiments.
Example (b):
a household garbage dehydration device is shown in figure 1 and comprises a motor 1, a speed reducer 2, a transmission mechanism 3 and a dehydration device 4, wherein the motor 1 is connected with the speed reducer 2, and the speed reducer 2 is connected with the dehydration device 4 through the transmission mechanism 3; the motor 1 is used for reducing the speed through the speed reducer and then driving the dehydration device 4 to dehydrate the garbage through the transmission mechanism 3.
As shown in fig. 2, the dewatering device 4 comprises a dewatering cylinder 5, a feed inlet 6 is arranged at the top of the dewatering cylinder 5 close to the transmission mechanism 3, and a discharge outlet 7 is arranged at the end of the dewatering cylinder 5 far from the transmission mechanism 3; of course, the garbage with larger water content enters from the feeding hole, and then the dehydrated garbage comes out from the discharging hole 7.
Specifically, a rotating shaft 8 is arranged in the dewatering cylinder 5, one end of the rotating shaft 8 is connected with the transmission mechanism 3, and the other end of the rotating shaft extends to the discharge port 7 and is fixed by the dewatering cylinder 5; the fixation ensures that the rotating shaft 8 can rotate, the conveying sheet 9 is arranged on the rotating shaft 8, and the conveying sheet 9 is spirally arranged around the rotating shaft 8; carry piece 9 through spiral ring and can extrude rubbish to the discharge gate by feed inlet below extrusion to under the pressure effect, moisture in the rubbish is extruded.
The feeding hole 6 is provided with a feeding funnel 10, a spiral guide piece 11 is arranged in the feeding funnel 10, the feeding funnel 10 facilitates feeding, but the direct feeding easily causes uneven distribution of garbage in the dehydration 5, so that the partial dehydration effect is not good, the guide piece 11 can guide the garbage to enter the dehydration cylinder 5 orderly, enter the spiral conveying piece 9 in the interval and be pushed to move towards the discharging hole by the conveying piece 9.
In order to improve the dewatering effect, the following improvements are made:
firstly, the outer diameter of the rotating shaft 8 at the feed port 6 is smaller than that of the rotating shaft 8 at the discharge port 7; and the outer diameter of the rotating shaft 8 is gradually increased from the feed inlet 6 to the discharge outlet 7.
Secondly, the height of the conveying sheet 9 at the feed port 6 relative to the rotating shaft 8 is greater than that of the conveying sheet 9 at the discharge port 7 relative to the rotating shaft 8. That is, in the drawing, the conveying blade 9 on the rotating shaft 8 is larger in size near the end of the transmission structure on the right side, and the conveying blade 9 on the rotating shaft 8 is smaller in size near the end of the discharge port. Specifically, the height of the conveying sheet 9 on the rotating shaft 8 is gradually narrowed from the feeding hole 6 to the discharging hole 7. This height is expressed as the size of the conveying sheet 9.
Thirdly, simultaneously, the outer diameter of the dewatering cylinder 5 is gradually reduced from the end of the feed inlet 6 to the end of the discharge outlet 7.
The three points are matched, so that the dehydration efficiency of the garbage in the dehydration cylinder 5 can be improved, and the whole garbage treatment efficiency is improved.
In the dewatering cylinder 5, water is squeezed out by squeezing, but the dewatering effect of the garbage can be ensured only by timely draining the water. In the present application, a water outlet groove 12 is arranged at the bottom of the dewatering cylinder 5 from the end of the feed inlet 6 to the end of the discharge outlet 7, and a water outlet hole 13 is arranged on the inner side wall of the water outlet groove 12, as shown in fig. 3 and 4.
Further improved drainage mode will the part or all that the axis of rotation 8 is located dewatering cylinder 5 is the hollow shaft, has seted up waterlogging caused by excessive rainfall hole 14 on the axle wall, and waterlogging caused by excessive rainfall hole 14 is with the inside and outside intercommunication of axis of rotation 8, because rubbish is at the extrusion in-process, all contacts and all has certain pressure to 5 inner walls of axis of rotation 8 and dewatering cylinder, and that water must all be extruded at two interfaces, consequently, through the drainage of axis of rotation 8, can reach the purpose of timely drainage, specifically as shown in figure 5.
If the discharge gate is opened, must reduce the pressure that rubbish bore in dewatering tube 5, consequently discharge gate 7 sets up ejection of compact structure 15, and ejection of compact structure 15 guides the rubbish ejection of compact on the one hand, and on the other hand carries out orderly control to the ejection of compact, makes the discharge gate can bear certain pressure to improve the pressure that rubbish bore in dewatering tube 5, the increase of pressure must improve the dehydration effect of rubbish. Specifically, as shown in fig. 6, the discharging structure 15 includes a discharging barrel 16 fixed to the end of the dewatering barrel 5, the discharging barrel 16 has a cavity which is a discharging cavity 17, the discharging cavity 17 is an arc-shaped cavity, and an opening is formed at the end of the cavity. Specifically, the discharge cavity 17 is an arc-shaped cavity, and the angle of the arc is greater than 90 degrees. Like this, because the open state of discharge gate 7 department has been avoided to the play material chamber 17 for the rubbish ejection of compact is not so smooth and easy, thereby has improved the rubbish bearing pressure in the dewatering cylinder 5, has improved rubbish dehydration effect.
Although the present invention has been disclosed in the preferred embodiments, it is not intended to limit the present invention, and any person skilled in the art can use the above-mentioned method and technical contents to make possible changes and modifications to the technical solution of the present invention without departing from the spirit and scope of the present invention, therefore, any simple modification, equivalent changes and modifications made to the above embodiments by the technical substance of the present invention all belong to the protection scope of the technical solution of the present invention.
