Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flow rate adjusting tank of a sewage purification device for treating sewage.

[0002]

[Prior art]

 Conventionally, in factory-certified sewage treatment equipment, if the bottom of the inflow pipe to the equipment is deep, the whole is deep, and if it is extremely deep, a separate raw water pump up tank is installed. . In particular, if it is necessary to change the size of the bottom of the inflow pipe during the construction process after the specifications have been determined, it is difficult to change the specifications because the product is being manufactured, and it is inevitable that the entire product will be deeply buried. In that case, a raised frame for the manhole inspection hole is being constructed on site.

[0003]

[Problems to be solved by the device]

 As described above, in the conventional structure, when the water level between the flow rate adjustment tanks consisting of multiple tanks is different, the lower water level affects the overall water level, so the entire structure must be deeply filled. I don't get it. The present invention provides a flow control tank of a sewage purification device that maximizes the capacity of the tank even when there are such different water levels and prevents an increase in construction cost.

[0004]

[Means for Solving the Problems]

 In the present invention, in a flow control tank consisting of a plurality of tanks, a sewage pump for pumping water is installed in a tank with a low water level and a measuring tank is installed in a tank with a high water level. An adjustment valve is provided on the branch pipe, and the branch pipe is connected to a check valve provided on an advection pipe that connects a tank with a high water level and a tank with a low water level to connect one of the pumps It relates to a flow control tank of a sewage purification device that guides a part through an adjustment valve and overcomes the water pressure corresponding to the water level difference between the two tanks that acts on the check valve by the water pressure of the pumping water.

【Example】

 Next, an embodiment of the present invention will be described. As shown in FIG. 1, a pumping sewage pump 6 is built in a flow rate adjusting tank inflow tank 1 provided with an inflow pipe 5, a sand settling tank 3 and a bar screen 4. The pumping sewage pump 6 is connected to a transfer pipe 8 having a diameter of 50 to 65 mm for transferring sewage to a measuring container 7 provided in the flow rate adjusting tank measuring tank 2. Reference numeral 17 is an adjusting valve. Further, an advection pipe 9 having a diameter of 125 to 150 mm for advancing from the flow rate adjusting tank measuring tank 2 to the flow rate adjusting tank inflow tank 1 is provided, and the diameter on the side of the advection pipe 9 which flows out to the flow rate adjusting tank inflow tank 1 Install the check valve 10 of 125 to 150 mm. Here, an adjusting valve 11 is provided on a branch pipe 13 having a diameter of 40 to 50 mm branched from the transfer pipe 8, and the branch pipe 13 and the check valve 10 are connected via a cheese type joint 14 as shown in FIG. To connect.

In the above structure, when the sewage flowing in from the inflow pipe 5 passes through the sand settling tank 3 and the berth cleaner 4 and reaches a predetermined water level in the flow rate adjusting tank inflow tank 1, the sewage is stored in the pumping wastewater pump 6. By operation, it is transferred to the measuring container 7 provided in the flow rate adjusting tank measuring tank 2 through the transfer pipe 8. At this time, the pumped wastewater of the pumped wastewater pump 6 also flows into the branch pipe 13 through the adjusting valve 11, flows through the cheese type joint 14 as shown by the arrow to the left in FIG. The on-off valve 15 of 10 is closed. For this reason, the advancing of the sewage from the flow rate adjusting tank measuring tank 2 to the flow rate adjusting tank inflow tank 1 is stopped. If the pumping sewage pump 6 stops operating, the pressure of the pumping water pushing the on-off valve 15 of the check valve 10 disappears, the on-off valve 15 opens, and the sewage flows from the flow rate adjusting tank 2 to the flow rate adjusting tank 2. Advection to the inflow tank 1 (arrow to the right in FIG. 2). In this way, the water levels of the flow rate adjusting tank measuring tank 2 and the flow rate adjusting tank inflow tank 1 rise while leveling, so that the effective capacity of the flow rate adjusting tank measuring tank 2 having a higher water level can be utilized to the maximum extent. A communication pipe 16 is provided as a measure against overflow of the flow control tank measuring tank 2 having a higher water level, and the effective capacity of the flow control tank is utilized. In addition, in FIG. 1, reference numeral 12 is a raising frame.

[0007]

[Effect of the Invention] According to the present invention, it is not necessary to deeply fill the entire body by deeply filling only the inflow tank of the flow rate adjusting tank, and the formwork of members such as a raising frame at the time of manhole inspection is less required. This will greatly reduce construction costs.
