DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1, 2, 3, and 4.
FIG. 1 is a front sectional view showing an internal configuration according to a first embodiment of the present invention. FIG. 2 is a front sectional view showing the internal structure of the second embodiment of the present invention. FIG. 3 is a right side view of the first embodiment and the second embodiment. FIG. 4 is a perspective view of the upper and lower rollers shown in the first embodiment and the second embodiment.
A main body 1 of a multi-stage roller type dehydrator (hereinafter referred to as dehydrator) shown in FIGS. 1, 2, and 3 is a box that supports the basic mechanism of the dehydrator. A filter cloth belt 4 is provided in the main body 1 so as to be sandwiched between the upper and lower rollers 2 and 3. As shown in FIGS. 1 and 2, the upper and lower rollers 2 and 3 are arranged in series and provided in multiple stages. In this embodiment, the number of stages is three. However, since the dewatering performance is improved, the number of stages may be four to five. Moreover, when the diameter of the upper roller 2 is about 1.5 to 2 times the diameter of the lower roller 3, the floating body F can be sandwiched between the upper and lower rollers. In particular, the diameter of the upper roller 2 is desirably 150 mm or more. A synthetic sponge rubber 5 having a thickness of 3 to 5 mm is attached to the surface of the lower roller 3 as shown in FIG. 4 in order to improve the dehydrating effect of the floating body F. The synthetic sponge rubber 5 absorbs moisture from the floating body F, and the synthetic sponge rubber 5 that has absorbed the moisture is squeezed by the pressing force of the insulator 6 and the spring 7 that pulls the upper roller 2 and the lower roller 3 together. The filter cloth belt 4 is connected endlessly and is passed between the upper and lower rollers 2 and 3, and two stationary rollers 8 and 9 for returning the endless filter cloth belt 4 are provided on both sides of the multistage roller. In addition, an insulator 10 and a spring 11 for applying a tensile force to the filter cloth belt 4 are provided on the shaft of one stationary roller 9, and the filter cloth belt 4 is squeezed behind the stationary roller 9 on the final stage side of the multistage roller. A spatula 12 for scraping off the floating body F that has been dehydrated and attached is brought into contact with the filter cloth belt 4 and attached to the filter cloth belt 4, and a spatula for scraping off the floating body adhering to the upper roller 2 by being squeezed by the upper roller 2. 13, each upper and lower roller 2, 3 is provided with an insulator 6 and a spring 7 that attract each other as described above, and each upper, lower roller 2, 3 and a multistage roller are connected to each other by driving 14 15, and the idler gear 16 is provided, on the lower roller shaft 17 of the final stage on to connect the Giamota 18 that gently rotate, driving the lower rollers 2, 3 and filter cloth belt 4.
FIG. 2 of the second embodiment shows a roller dehydrator in which each upper roller 2 is connected by a rubber-clad endless belt 19.
In the figure, 20 and 21 are upper and lower roller shafts, and 22, 23, 24 and 26 are rotation support shafts. Reference numeral 25 denotes a bearing for the upper and lower roller shafts. Reference numeral 27 denotes a heavy object for pressing the spatula 13 against the upper roller 2.
Next, a detailed configuration and operation will be described.
The filter cloth belt 4 uses a polyester fiber mesh or the like, and is preferably made of a material having water resistance, durability and wear resistance. Moreover, the belt of an Example employ | adopts the textile fabric which is hard to meander.
The core material of the upper and lower rollers 2 and 3 may be a water-resistant and wear-resistant plastic. In this embodiment, a hard vinyl chloride pipe material is used. Further, as shown in FIG. 4, a synthetic sponge rubber 5 having a good water resistance and a thickness of 3 to 5 mm is wound around and adhered to the lower roller 3. The upper roller 2 may be a plastic material, but the larger the diameter is 150 mm or more, the better the sandwich of the floating body F is. Further, a synthetic rubber sheet having a thickness of 1 to 2 mm may be wound around and adhered to the outer peripheral surface. However, a water-repellent material that is difficult to attach the floating body F is preferable.
There are two stationary rollers 8 and 9 for returning the endless filter cloth belt 4 on both sides of the multi-stage roller, but the rollers 8 and 9 are intentionally stopped (not rotated) so that the filter cloth Since the floating body F attached and squeezed to the belt 4 is pushed out to the front side of the filter cloth belt 4 by friction, the scraping effect by the spatula 12 becomes remarkable. (It works like the back of a mesh with cooking.)
The spring 7 that pulls the upper and lower rollers 2 and 3 toward each other has a higher dehydrating effect if the spring force is increased as the first, second, third, and subsequent stages. Of course, if there is a margin for the mounting location and cost, the greater the number of stages, the better the dehydration effect.
The upper and lower rollers 2 and 3 and the multistage roller are provided with gears 14 and 15 and an idler gear 16 connected to each other, and the lower roller shaft 17 on the final stage side is connected with a gently rotating gear motor 18. The lower rollers 2 and 3 and the filter cloth belt 4 are driven in multiple stages. Therefore, even if the floating body F is slippery and in the form of grease, there is an effect that the slip phenomenon of the filter cloth belt 4 does not occur. However, when the floating body F is in the form of a fiber that is difficult to slip, the number of gears to be connected may be reduced.
Further, in FIG. 2 of the second embodiment, when each upper roller 2 is connected by a rubber-clad endless belt 19, a rubber-clad endless 19 is required, but it is squeezed by the upper roller 2 and dehydrated and adhered. The number of spatulas 13 for scraping off the floating body can be reduced from three to one. Therefore, it may be determined each time whether the first embodiment or the second embodiment is selected according to the type or hardness of the floating body F.
Next, the operation method of the present invention and examples will be described. 1 and FIG. 2 continuously inject water and floating body F floating in the water from the inlet A shown on the left side A of the main body 1. The upper and lower rollers 2, 3 are rotated by the gear motor 18, and the filter cloth belt 4 is drawn and moved in the right direction in the figure, and water is naturally dripped downward through the filter cloth belt 4 and contains water. The floating body F is sandwiched between the upper and lower rollers 2 and 3 together with the filter cloth belt 4, and the contained water is squeezed out. Further, the contained water is squeezed out by the second and third rollers and the lower rollers 2 and 3 and dehydrated. The dehydrated floating body F is scraped off by the spatula 12 and the spatula 13 and discharged from the outlet indicated by B in the figure. The squeezed water flows out from the drain C downward.

【The invention's effect】
As described above, the multi-stage roller type dehydrator of the present invention rotates while sandwiching the filter cloth belt, and the lower rollers are arranged in series and provided in multiple stages, so that the dehydration effect is remarkable. In addition, since the configuration is simple, the cost can be reduced compared to a conventional heavy device. Moreover, the diameter of the upper roller is about 1.5 to 2 times the diameter of the lower roller, so that the floating body F can be sandwiched between the upper roller and the lower roller. In particular, since the upper roller has a diameter of 150 mm or more, the pinching is good and the dewatering effect is improved. A synthetic sponge rubber having a thickness of 3 to 5 mm is attached to the surface of the lower roller in order to improve the dehydrating effect of the floating body F and the pinching of the floating roller into the upper roller. The synthetic sponge rubber absorbs moisture from the floating body F, and the synthetic sponge rubber that has absorbed moisture is efficiently squeezed out by the squeezing force of the insulator and spring that pulls the upper roller and the lower roller together. There are two stationary rollers on both sides of the multi-stage roller to return the endless filter cloth belt, but this roller was intentionally stopped (not rotated) and stuck to the filter cloth belt. Since the floating body F is forcibly pushed out to the front side of the filter cloth belt by friction, the scraping effect by the spatula becomes remarkable. (It works like cooking back.)
Furthermore, gears that are connected and driven are provided between the upper and lower rollers and the multi-stage rollers so that even if a slippery floating body enters, the filter cloth belt or roller does not slip, especially sludge. Thus, a dehydrator that exhibits a number of effects can be provided, such as stable dehydration even when the aggregation of the floating body is weak or the size of the floating body (also referred to as floc) is small.
