Description of the Invention: [Technical Field] The present invention relates to a closed water filtration device, and more particularly to a closed rotary membrane device that can tolerate large turbidity of sewage. [Prior Art] The known reverse osmosis membrane group comprises a plurality of membranes sandwiched between two sheets by a mesh, and a water inlet network interposed between adjacent membranes. The above-mentioned member is wound on a central tube and is concentrically shaped. The tube body is placed in a ceramic tube shell, and the two ends are respectively sealed by a plug cover to form a spiral package. (Spiral_w〇und) membrane tube, wherein the sheet is only a water dialysis membrane (commonly R0 membrane), the membrane is separated by a mesh, so that a water producing channel is formed inside, similarly Adjacent filter membranes are formed by the inlet web to form a water inlet channel parallel to the axial direction of the shell. The reverse osmosis membrane group drives the feed water into the shell with a water pressure of about 5 to 75 bar in use, so that the feed water is fed into the water inlet channel along the gap of the water inlet network, the water inlet network. In addition to forming the inlet channel, the effect can also cause the feed water to form a turbulent flow when it is introduced into the water inlet channel, so as to inhibit the deposition of solids in the water on the membrane surface of the membrane, and then the water in the feed water will dialyze into the water channel. In the inner tube, the tube is collected and stored outside, and the solid in the original feed water remains in the inlet channel, and a concentrated solid waste of high solid density is gradually formed, and then the shell is discharged. 1324082 This spiral-wrapped reverse osmosis membrane group has the following disadvantages because of its high packing density, although it has a high surface area per unit volume: The suspended solids and rubber feathers in the water make the filter membrane easy to block, so it is necessary to have a good pre-treatment process and equipment. Moreover, in order to increase the flow of water, only the addition of the membrane tube can improve the circulation of water. The amount of film tube equipment is bulky and costly. First, the concentrated waste liquid formed during water production must be re-filtered and chemically treated to meet the discharge standard. In addition to the two cost treatments, more serious environmental problems are also generated. Third, the water inlet network will also reduce the area of the diafiltration membrane that allows the water body to be diafiltered. In addition, the small gap of the inlet network itself also forms a space for accumulating organic matter such as solids and sludge, which greatly reduces the feed water entering the water inlet channel. The space, which in turn causes the attenuation of the filtrate flow rate, seriously affects the filtration performance of the membrane. In order to overcome the problem of the spiral-clad reverse osmosis membrane group in the past, the applicant of the present application has previously filed a patent application for the "Rotary Water Treatment Device" of the application No. 095123220, revealing a filter plate which can be made into a plate shape. Laminating the membrane plate 'and the center of the membrane plate is pierced by a hollow shaft and watertightly locked. The water treatment device is pivotally placed in a treatment tank in a semi-immersive manner, and one end of the hollow shaft can be A power unit is coupled to produce rotation. Therefore, when the hollow shaft is driven by the power unit, and then the entire diaphragm of the outer circumference is rotated, the membrane in the swirling contact with the feed liquid in the treatment tank will 'suppress the sludge accumulated on the membrane surface. The solid particles produce a shearing action to achieve the effect of inhibiting the deposition of the membrane sludge (filter cake); however, 6 ^ 24082 the water treatment device is semi-settling in the treatment tank, so in the tank In the case of non-closed, only the negative pressure (vacuum) can be used to extract the clean water through the membrane. 'The negative pressure of the water production is quite limited, and it is not suitable for environmental equipment that requires a lot of wastewater treatment." To this end, the applicant also thought that the entire water treatment device should be completely immersed in the closed treatment tank for the transition, but because the membrane surface is completely in contact with the water body, when the membrane is rotated, the feed water in the treatment tank can only be presented. In the steady flow state, the original contact shear force of the membrane surface and the water body does not exist, causing the membrane cake to be easily formed. 'Additional'. With the increase of the solid density in the water in the treatment tank, there will also be concentration polarization. Phenomenon 'usually It is also possible to discharge only the wastewater directly, and it is unable to meet the requirements of zero discharge of the wastewater. Therefore, how to improve the water production throughput, reduce the problem of membrane blockage, and zero discharge of wastewater has become an urgent problem for the present invention. . SUMMARY OF THE INVENTION Therefore, the object of the present invention is to provide a closed-rotating filter device that uses a power source to drive a filter unit in a closed chamber to perform a rotary motion, so that the feed water can be driven by a positive pressure to filter the filter. Tolerate large turbidity of the sewage' and avoid concentration polarization, thereby increasing the amount of water produced. Another object of the present invention is to provide a hermetic swirling membrane device' to control the valve to control the water in the closed chamber for circulation and re-filtration to obtain zero discharge of wastewater, and to meet environmental benefits. Another object of the present invention is to provide a closed-rotating filter device that allows the original steady flow of feed water to pass through the barrier of the disturbance member, and enters 7 1324082 to generate radial and axial turbulence interactions. #,u Reduce the fouling of the surface and increase the periodicity of the use of the filter.

The purpose of zero emissions. In addition, the shaft tube unit 400 further has an exhaust pipe 470 connected to the water producing port 45〇, and the exhaust pipe 470 is for discharging the air originally stored in the hollow shaft 410 and the second outer shaft segment 430 to the filter drum. 1〇〇, in order to avoid the water can not be dialyzed into the membrane group 310' and generate gas resistance. Referring to Figures 1 and 4, the support foot 600 is used to support the filter drum 100, the power unit 200, the shaft tube unit 3, the filter unit 400, and the bearing housing 500, and the bearing housing 5 〇〇 is disposed at both ends of the shaft tube unit 4' to withstand the dynamic load of the rotational motion. When the power unit 2〇0 drives the shaft tube unit 400 to operate synchronously with the filter unit 3〇〇 (including the continuous operation of 1324082 'turn and intermittent forward/reverse rotation), the filter and membrane unit are considered as ' The filter drum 100 is rotated in rotation, and the rotation speed is about 3 〇 8 〇 rpm, thereby rotating the movement to prevent the concentration polarization phenomenon caused by the accumulation of mud in the water body to generate the filter cake, and then the conventional Compared with the film of (10), the film of the sealed rotary diaphragm device of the present invention is less prone to fouling, so the amount of water produced will be greatly improved under the same operation time. Referring to FIG. 5, in addition, an inner wall surface 1〇1 of the filter drum 100 is provided with φ having a plurality of ribs I90 and 191, and the adjacent ribs 190'191 have a cross-sectional length which is jagged. A drop d is formed. Moreover, the ribs 190 and 191 do not touch the filter group 31〇 of the filter unit 3〇〇, and are arranged in a staggered manner with the membranes of the filter unit 300, so that the water body can flow in the axial direction. Effect. Thereby, when the filter unit 3 turns into a rotary motion, causing the water body to generate a radial throwing flow (as indicated by the arrow in the dotted line), the radially flowing water body will be generated with the water body flowing in the axial direction. The effect of interactive perturbations. Therefore, in addition to the disturbance of the water body of the closed chamber 130 (see Fig. 1) by the rotation of the power unit 2, the present invention is supplemented by the water wave flow generated by the (10) 190, 191 of the filter drum 100. The interaction between the two bodies of water body can obtain the effect of unsteady turbulence disturbance, effectively reduce the fouling of the membrane surface and the formation of the filter cake. The membrane group 310 can withstand higher sewage turbidity and avoid concentration. Polarization and increase the operating cycle. Referring to Fig. 6, Fig. 7, and Fig. 8, the second embodiment of the hermetic swirling membrane device of the present invention has the same general construction as that of the first embodiment, and will not be described again. The second embodiment differs in that the water deflector 33 〇 12 1324082 has a one-piece body 331 and a plurality of agitating ribs 332 extending radially from the annular body 331. The filter drum 1 has an annular rib 102 extending continuously in the axial direction and continuously rewinding around the inner wall surface. The other detailed structure of the water deflector 330 is not the focus of this case, and will not be described again; the detailed structure of the water deflector has been detailed. In the invention patent application of the "Rotary Water Treatment Device" of Application No. 095123220. Referring to FIG. 8 'When the filter unit 3 〇〇 generates a rotational motion, causing the water body to generate a radial throwing flow, the agitating rib 332 of the water deflector 33 disturbs the water body to generate a circular motion, at this time, the circular motion The water body impinges on the surfaces of the agitating ribs 332, and then generates a radial flow of water along the surfaces of the agitating ribs 332, so that the radially flowing water body interacts with the circularly moving water body, and then throws the filter barrel into the filter barrel. The water body ' of the inner wall 101 of 100 is further axially disturbed along the spiral annular rib 1 〇 2 to increase the perturbation effect. Through the above description, the sealed rotary membrane device of the present invention has the following effects: 1. The filter unit 3 in the closed chamber 130 is driven by the power source to perform a rotary motion, which can tolerate a large degree of contamination, and further avoids The mud is deposited on the surface of the film. In addition to the fouling of the film, the feed water can be driven by positive pressure to increase the water production. Second, the water return pipe 700 is connected between the filter drum 100 and the water inlet 14 〇 and the water outlet 150, and the control valve 160 is used for valve control, so that the water body of the chamber is recycled and filtered to obtain zero water.
