ものである。[Detailed description of the invention] This invention relates to a cloth traveling type dewatering device.
The purpose of this invention is to provide a means for detecting the flow rate of excess water flowing down from the natural dehydration section of the dehydration apparatus, and to manage the operation of the dehydration apparatus based on the flow rate of the excess water.

て凝集汚泥の脱水を行なう。 That is, first, the sludge in the sludge tank 1 and the flocculant in the flocculant tank 2 are transferred by the slurry pump 3 and the metering pump 4, respectively, and flow into the rotating agitator 5 to thoroughly mix the sludge and the flocculant. Next, flocculated sludge 6
The sludge is dropped onto a liquid-permeable first cloth 7 running almost horizontally, and the relatively easily desorbed water in the flocculated sludge is passed by gravity, and the excess water is received by a receiving pan 8 attached at the bottom. Discharge outside. On the other hand, the first cloth 7 is reversed by the reversing roll 9, and the flocculated sludge 6 is subsequently caused to fall onto the liquid-permeable second cloth 10. Second
Since the cloth 10 is also traveling approximately horizontally, the moisture that is relatively easily released is further filtered by gravity during this time, and the excess water is received by the pan 8' and discharged to the outside.
After passing through the natural dewatering section where water is removed by gravity, the flocculated sludge is transferred to the first cloth 7 and the second cloth.
The first cloth 7 and the second cloth are sandwiched between cloths 10 and passed through a number of rolls 11 to be dehydrated by pressing, and finally dehydrated by pressure by a pressure belt 12. Separate the two cloths 10 and remove the dehydrated cake remaining on the top of the second cloth 10 with the scraper 1.
Similarly, the dehydrated cake remaining on the first cloth 7 is also scraped off by the scraper 13'. After scraping off the dehydrated cake, the first cloth 7 and the second cloth 10 are sprayed onto the spray nozzles 14 and 1.
4', and the above-mentioned operation is repeated again to dewater the flocculated sludge.

定する。 The structure and operation of conventional cloth running type dewatering equipment are as described above. Usually, a beaker test and a small experimental device are conducted on the sludge to be treated in advance to determine the optimum amount of flocculant to be added and cloth running type dewatering equipment. Determine the optimal running speed, etc.

速度と云える。この最適な布の走行速度を測定
する場合、通常、布走行型脱水装置の小型実験
装置の運転によつて決定する。 To briefly explain how to measure the optimal amount of flocculant added and the optimal running speed of the cloth, first, the optimal amount of addition is determined by dividing the sludge to be treated into several beakers, and adding the flocculant to the beakers. After adding the sludge by changing the amount in stages, stirring and reacting each time, the flocculated sludge is passed through a sieve of about 60 mesh to measure the elapsed time and liquid volume, and the amount obtained by the sieve is measured. The dehydrated sludge is manually squeezed using a cloth with approximately 60 meshes, and the ease of squeezing out residual water and peelability are observed, and the optimum amount to be added is determined from both the permeability and peelability. On the other hand, when explaining the running speed of the cloth, the speed is closely related to the moisture content of the dehydrated cake; if it runs too fast, the desired moisture content cannot be obtained, and conversely, if it runs too slowly, the desired moisture content cannot be obtained. On the other hand, processing capacity decreases. Therefore, the optimum cloth running speed can be said to be the fastest speed at which the moisture content of the dehydrated cake reaches a predetermined value. When measuring this optimum cloth running speed, it is usually determined by operating a small experimental device of a cloth traveling type dehydrator.

ンプ４の設定吐出量が変化する場合もある。 In conventional fabric running type dehydration equipment, operation is started based on the optimum amount of flocculant added and the optimum running speed of the fabric obtained through the beaker test and the operation of the small experimental device described above. Since the concentration of sludge changes to some extent depending on the operating state of the sludge thickening device installed in the previous stage, the two optimum values may deviate from each other. Further, the set discharge amount of the sludge slurry pump 3 or flocculant metering pump 4 may change.

では布の走行速度が最適か否か判定できないか
らである。 However, the conventional cloth traveling type dewatering apparatus does not have a means to detect deviations from these optimum values, making operation management extremely difficult. Currently, operations are managed by measuring the moisture content of the dehydrated cake obtained or observing its properties, but measuring the moisture content is complicated and difficult to use in the field. is not suitable for operation management of cloth traveling type dewatering equipment. This is because, as mentioned above, the optimal running speed of the cloth is the fastest speed at which the moisture content of the dehydrated cake reaches a predetermined value, so even if the moisture content is at a predetermined value, this value alone will not work. This is because it cannot be determined whether the running speed of the cloth is optimal or not.

であるので説明を省略する。 FIG. 2 is a cutaway vertical cross-sectional view of the main part of the present invention.
The feature of this invention is that the receiving pan 8 has a partition plate 1.
7 and 17' are installed upright, the overwater receiving gutter 1
8, and the receiving gutter 18 and the flow rate detection means 19 are communicated with each other through a communication pipe 20. The flow rate detection means 19 in this embodiment consists of a retention tank 21, an overflow weir 22, electrodes 23, 23', and an overflow tank 24, but any device can be used as long as it can detect the flow rate of water. I can't resist. The other parts of the device of the present invention are the same as those of the conventional cloth traveling type dewatering device, so the explanation will be omitted.

Needless to say, the excess water existing outside the tube 7' is discharged to the outside as in the conventional device described above.

ようにしておく。 By such an operation, the flocculated sludge 6 mixed by the stirrer 5 falls onto the first cloth 7 running approximately horizontally, and the natural dewatering as described above is started by this portion. The naturally dehydrated flocculated sludge 6 is then sandwiched between the first cloth 7 and the second cloth 10, and the process proceeds to the above-mentioned compression dewatering.
In the present invention, a part of the excess water obtained from the natural dehydration section is received by the receiving gutter 18, and the excess water is transferred to the communication pipe 2.
0 flows down and flows into the retention tank 21. Retention tank 2
1 is filled with a certain amount of excess water, the excess water overflows the overflow weir 22, but at this time, a water whose height changes proportionally depending on the flow rate is placed directly above the overflow weir 22. As a layer is formed, electrode 23 is set so that the tip of electrode 23 contacts the top of the water layer. Further, the electrode 23' is also set so that the tip of the electrode 23' is located slightly above the electrode 23.
Note that the following instrumentation considerations should be taken for both electrodes 23 and 23'. That is, when the flow rate of excess water decreases and the water layer formed directly above the overflow weir 22 and the tip of the electrode 23 are separated, and when the flow rate of excess water increases and the water layer forms directly above the overflow weir 22 and the tip of the electrode 23' become separated. Alerts should be sent to both parties in the event of contact.

２３の先端が離間し警報を発する。 For example, if the concentration of sludge to be treated increases, or if the set flow rate of the slurry pump 3 or metering pump 4 changes, the optimum flocculation range will be exceeded, resulting in poor flocculation. The flow rate of inflowing excess water decreases. Therefore, the water layer formed directly above the overflow weir 22 and the tip of the electrode 23 are separated, and an alarm is issued.
