Abstract

(57) Abstract: An object of the present invention is to provide a device for cleaning sludge such as sludge mixed with gravel and for continuously separating the sludge. The present invention comprises a cleaning device (2), a separation device (3) connected in communication with the cleaning device (2), and a filtering device (1), and contaminated water generated by the cleaning device (2) is filtered by the filtering device (1). At the same time, the mechanism is such that the filtered water is reused as cleaning water for the cleaning device 1.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an apparatus for separating substances such as gravel or sludge, which are mixed in various sizes, and separating them into sand of each particle size.

[0002]

[Prior art]

 Conventionally, as a mechanism for cleaning gravel in which mud and sand are mixed, there is a device that puts gravel in a reticulated rotary drum and flushes mud while spraying water into the drum. In the case of sludge, which has a very high water content, the sediment layer is first used to separate water and solids, and the separated solids are used for landfilling, etc. There is no work to separate sand from solids. is the current situation.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned gravel cleaning device, the water sprayed during cleaning is discharged as it is, which may cause secondary pollution. Since it is done by the equipment, there is a problem that work efficiency is very poor. In addition, sludge and the like require large-scale auxiliary equipment, and further, in order to separate solid matter into gravel, several steps are required, which is very troublesome and costly. Therefore, in order to solve the above problems, it is an object of the present invention to provide an apparatus capable of continuously performing cleaning and sorting.

[0004]

[Means for Solving the Problems]

 The above object of the present invention can be achieved by a device having the following configuration. That is, the gist thereof is a cleaning device composed of a cleaning rotary part composed of a mesh-shaped rotary drum, and a water jet pipe arranged along the cleaning rotary part, and the cleaning device. A rotary part for separation consisting of a mesh-shaped rotary drum and a contaminated water generated from the rotary part for cleaning are filtered, and the filtered water is circulated again to the water jet pipe. It is a cleaning and sorting device for gravel, etc. Further, by continuously providing a plurality of the separating rotary parts, it becomes possible to separate the washed gravel into several kinds of diameters.

[0005]

[Embodiment of device]

 Embodiments of the present invention will be described in detail with reference to the drawings based on examples. As shown in FIGS. 1 and 2, a cleaning device 2 is installed on the filtration device 1, and a separating device 3 is connected to the cleaning device 2 in a communicating manner.

Therefore, in the mechanism of the filtration device 1, a cloth-shaped filtration belt 5 that allows only moisture to pass is wound around each of the pulleys 4, 4, ... It is a mechanism. The hopper 6 of the cleaning device 2 is provided above the starting end side of the filtration belt 5.

Then, the pulley-4 width between the starting end side and the terminating end side of the filtration belt 5 is reduced by a constant interval to make the filtration belt 5 slack in a U-shape and further to filter the filtration belt 5. The air jet pipe 7 is arranged around the belt 5. Further, a filtered water accumulation layer 8 is provided below the U-shaped filtration belt 5.

Next, the mechanism of the cleaning device 2 is composed of a mesh-shaped cleaning rotary portion 9 and water jet pipes 10 arranged along both sides of the cleaning rotary portion 9. Is. Therefore, the water jet pipe 10 is arranged in the filtered water accumulation layer 8 of the filtration device 1, and a pump 11 ejects the filtered water in the filtered water accumulation layer 8 into the cleaning rotary unit 9. It is what

Further, one end side of the cleaning rotary portion 9 is used as an inlet 12 for gravel or the like, and a mesh-shaped separating rotary portion 13 is connected to the other end side in a communicating manner. is there. In the separating rotary part 13, the gravel having a particle size smaller than a certain size is dropped to the lower part according to the mesh size, and the gravel having a particle size larger than that is discharged from the outlet 14 of the separating rotary part 13. Mechanism.

Further, a feeding blade 15 is included between the cleaning rotary portion 9 and the sorting rotary portion 13, and the feeding blade 15 compulsorily separates the gravel. -It is a mechanism for feeding to the tarry section 13. By connecting a plurality of sorting rotary parts 13, it is possible to continuously sort gravel of several particle sizes.

Therefore, as shown in FIG. 3, the sludge B thrown into the cleaning rotary unit 9 is cleaned by the water jet pipe 10 while rotating in the cleaning rotary unit 9. . In this case, the polluted water C generated by the washing is dropped from the hopper 6 to the filtration device 1, filtered by the filtration belt 5, stored in the filtration water accumulation layer 8, and again pumped by the water jet pipe 10 by the pump 11. It is used as wash water.

Further, as shown in FIG. 4, the washed gravel D is forcibly sent into the sorting rotary section 13 and the sorting rotary section 13 causes the gravel D having several particle diameters. Is to be separated. As the mechanism of the filtering device 1, various mechanisms other than the mechanism shown in this embodiment are conceivable, and it is desirable to adopt a mechanism most suitable for the situation.

[0013]

[Effect of device]

 As described above, according to the present invention, sludge mixed with gravel such as sludge is continuously washed and separated while filtering the contaminated water generated during washing and reusing it as washing water. It is possible to carry out continuously, and it is economical and has excellent workability.
