Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a filtration device, and more particularly, to a self-cleaning filtration device capable of collecting solids from sewage filtration or liquid and discharging the same outside the device.

[0002]

[Prior art]

 However, with the emphasis on environmental protection, it is common practice to first pass used industrial wastewater through a filtration device to precipitate suspended solids in wastewater before discharging it from the factory before discharging it. It is before standing. In the conventional industrial wastewater filtration device, a bypass passage and a multilayer filter material are disposed inside the filter, and when the pump sucks the sewage into the filter device, the sewage flows through the bypass fil- ter and the multilayer filtration device. After the material has been filtered and the solids have settled, only the water flows out. Therefore, if used for a certain period of time, a considerable amount of solid sludge or sludge will always accumulate inside it, and if not cleaned in a timely manner, it will affect subsequent sewage filtration treatment. Each time the sediment in the filtration unit must be treated. That is, the conventional industrial sewage filtration apparatus performs the function of sewage filtration in use, but still has the following disadvantages. (1) Since the filtration of sewage and the treatment of sediment are carried out completely separately, when arranging the filth in the filtration device, the operation of the entire filtration device must be stopped, in other words, the cleaning of the sediment. During this time, the filtration device must be shut down. (2) As described above, since the filtration of sewage and the removal of sediment are performed separately, extra time and labor are required for cleaning the sediment and sludge, which is extremely inconvenient. (3) Since the filtration process is performed by providing a bypass in the filtration device, the time required for sewage filtration in the device is too long. (4) Take up space because the volume is too large.

[0003]

[Problems to be Solved by the Invention] In view of the above-mentioned problems in the conventional sewage filtration apparatus, the present invention provides a self-cleaning filter capable of collecting sludge solids from a sewage filtration or liquid and simultaneously discharging the sludge to the outside of the apparatus. It is intended to provide a device.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention separates a water absorption zone, a dewatering zone, and an exclusion zone in order from the lower end to the upper end of the frame, and installs a transport device around these zones. The water-absorbing zone is immersed in a sewage pond to communicate with a circumscribing pump, and at the same time as the pump pumps out sewage, dirt in the sewage adheres to the transport device and is transported together with the transport device. After moving up to the dewatering zone and performing aeration drying in the dewatering zone, the filth adheres and stays on the transport device as it is, and the transport device moves upward and rotates to reach the exclusion zone, and further from the exclusion zone. When changed to the downward movement rotation, the relatively heavy filth adhered to the transport device dropped by its own weight, and then the relatively light filth adhered and accumulated on the transport device was generated in the elimination zone. It ’s blown off by the wind Configured.

[0005] In addition to the above-mentioned transportation device, a transmission device is provided, and the transmission device is mounted adjacent to the upper end of the exclusion zone and a sub-transmission member provided adjacent to the lower end of the water absorption zone. Wherein the transport device is a net-shaped transport belt, and both ends of which are respectively provided around a main transmission member and a sub-transmission member of the transmission device, and a longitudinal direction of the transport device between the two transmission members is included. Both sides are brought into contact with the water absorption zone, the dewatering zone and the exclusion zone, and circular filtration nets are attached to both sides of the water absorption zone, respectively. By performing a filtration treatment that is one step further, by connecting a suction blower to the dehydration zone, if the dirt attached to the transport device moves upward and reaches the dehydration zone, It is dehydrated and dried by the air blown by the suction blower and is retained in the transportation device by sticking. A sword is provided in the exclusion zone, and the blade of the sword is formed substantially downward. It is even more preferable to be able to blow off relatively light sewage that has adhered and accumulated on the floor.

In the present invention configured as described above, when the pump connected to the water absorption zone immersed in the sewage pond is driven and driven, the sewage in the sewage pond is used as a net-like transport device and a circular filtration device on both sides of the water absorption zone. The water flows into the water absorption zone through the net and is sucked into the pump, but before the sewage flows into the water absorption zone, the filth contained therein adheres to the net transport device, and the waste water of the net transport device is removed. It moves upward to the dewatering zone with the rotation, and is dehydrated and dried by the suction air from the suction blower communicating with the dewatering zone, stays in the transporting device with adhesive, and furthermore, the transporting device moves upward and rotates to be removed. When the zone is reached, and subsequently the rejection zone is changed to a downward movement rotation, the relatively heavy waste sticking to the mesh transport device first falls by its own weight, and then adheres and stays in the transport device. Relatively light filth is blown off by a wind blade located in the exclusion zone. In other words, the present invention can filter sewage through the above-mentioned work, and can separate sewage from sewage to collectively store and eliminate the sewage.

[0007]

[Embodiment of the invention]

 Hereinafter, the present invention will be specifically described based on an embodiment, but the present invention is not limited to this example. Figures 1 and 2 show a relatively preferred embodiment of the "self-cleaning filtration device" of the present invention, which was separated from sewage at the same time as sewage filtration or separation of solids from liquid. Waste can be discharged out of the device. Then, the water absorption zone 1, the dewatering zone 2 and the exclusion zone 3 are sequentially partitioned from the lower end to the upper end of the frame 16 mainly including the frame 16, and the transmission device and the transport device 4 are provided. The transmission includes a main transmission member 50 attached to the upper end of the exclusion zone 3 and driven by a motor 52, and a sub transmission member 51 provided at a lower end of the water absorption zone 1. A net-like transport belt, which is laid across the main transmission member 50 and the sub-transmission member 51, and which rotates when the main transmission member 50 rotates. The transportation device 4 is rotated around the circumference of the transmission device, and both longitudinal sides of the transportation device 4 are connected to the water absorption zone 1, the dewatering zone 2 and the exclusion zone 3. Touch.

As can be seen by referring to FIG. 3 in addition to FIGS. 1 and 2, the water absorption zone 1 is always immersed in the sewage pond 8, and the upper end surface 10 and the bottom surface 11 of the water absorption zone 1 are immersed. Has a closed surface, and the front and back surfaces 13 of the water absorption zone 1 communicate with a pipe body 60 through which water flows, respectively, and further communicate with a circumscribed pump (not shown). Suction is generated by generating a strong suction force, and circular filtration nets 15 are attached to both side surfaces of the water absorption zone 1, respectively, and both side surfaces 14 of the net-shaped transport device 4 are connected to the circular filtration nets 15 of the water absorption zone 1. Attach to outer edge. Thus, when the pump is driven, sewage flows into the water absorption zone 1 through the net-shaped transport device 4 and the circular filtration network 15 on both sides of the water absorption zone 1, and is further sucked into the pump through the pipe 60. However, before the sewage flows into the water absorption zone 1, the filth contained therein naturally adheres to the mesh transport device 4, and turns upward with the rotation of the mesh transport device 4. Move to. The mesh 40 of the transportation device 4 is formed smaller than the mesh 150 of the hole filtration network 15 so that any dirt in the sewage adheres to the transportation device 4. Of the wastewater into the water absorption zone 1 and the sewage sewage sucked into the water absorption zone when necessary, but most of the sewage in the sewage is already attached to the transport device 4. Therefore, the perforated filtration network 15 can be used for a considerably long period of time and then cleaned once.

[0009] Continuing with the description above, the upper end surface 20 and the bottom surface 21 of the dewatering zone 2 also exhibit a sealed surface, and a vent pipe 61 communicates with the front surface 22 and the rear surface 23 of the dewatering zone 2, respectively. It communicates with a draft blower (not shown). Then, a large number of through-holes 25 are opened in one side surface 24 of the dewatering zone 2 along which the transport device 4 rotates upward, and both side edges along the longitudinal direction of the mesh transport device 4 are connected to the dewatering zone 2. When the suction blower is driven and rotated, the dirt adhering to the reticulated transport device 4 and moving upward to the through hole 25 installation area of the dewatering zone 2 together with the mesh blower 4 is removed. It is dehydrated and dried by the air blown by the suction blower and adheres to the transport device 4.

Next, when the transport device 4 moves upward and rotates to reach the exclusion zone 3, and further moves downward from the exclusion zone 3, the relatively heavy sewage adhered to the mesh transport device 4. First, it falls by its own weight, and thereafter, relatively light dirt adhering and staying in the transport device 4 is blown off by the wind generated by the wind blade 30 with the blade 300 downwardly installed in the elimination zone 3 and the cutting edge 300 facing downward. It is. Then, in order to facilitate the cleaning of the waste, a container 7 is provided at an appropriate place to receive the waste falling from the exclusion zone 3.

[0011] That is, it is possible to filter the wastewater through the above-mentioned flow operation, and collectively store the waste separated from the wastewater in the container 7 simultaneously with the filtration of the wastewater to complete the filtration process. it can. However, if necessary, the filtered water sucked out from the pump may be further circulated to the sewage pond 8 to perform the filtration treatment once again or repeatedly. Should. The applicable range of the present invention covers fields such as "sludge recovery", "pulp recovery", "electric circuit board drying", and "solid-liquid separation in water".
