A sewage utilization retreat water culvert device

Abstract

The invention discloses a sewage utilization retreating water culvert device, which relates to the technical field of sewage utilization. It includes a square culvert body, a first sewage pipe and a second sewage pipe are arranged near the left and right sides of the square culvert body, a sealing mechanism is arranged between the first sewage pipe and the second sewage pipe, and the first sewage pipe The front side of the pipe is provided with a drain hole, and the front side of the second sewage pipe is provided with a water diversion hole, and the front side of the drain hole and the diversion hole are both provided with a filter mechanism, and the circle corresponding to the drain hole A drain pipe is provided on the front side of the square culvert body in front of the hole, and a water diversion pipe is provided on the front side of the square culvert body at the front side of the round hole corresponding to the water diversion hole. The invention occupies a small area, has a simple structure and low construction difficulty, solves the problem of the existing sewage water point spacing requirement, reduces the power consumption of the sewage lifting pump, and effectively avoids the blockage of the water diversion pipe and the water return pipe.

Description

technical field [0001] The invention relates to the technical field of sewage utilization, in particular to a sewage utilization retreat water square culvert device. Background technique [0002] In the sewage source heating industry, the traditional sewage utilization method is sewage source + heat exchanger + heat pump technology. The temperature of the tail water of direct heat exchange is generally 7°C. The heat source side is for the maximum utilization of sewage resources. The general design is 8°C. Due to the heat exchange requirements and the characteristics of the host, the inlet and outlet water temperature of the general host is designed to be 12 / 5°C. The average temperature of the heat pump host is lower, and the energy efficiency of the system is relatively small. If the inlet and outlet water temperature is increased, the sewage backwater cannot be controlled. Temperature, it is difficult to maximize the utilization of sewage resources. The user-side heating sp...

Problems solved by technology

[0004] The present invention provides a device for using the retired water square culvert for sewage, which has a small footprint and low construction difficulty, solves the existing problem of the distance between sewage water points, reduces the power consumption of the sewage lifting pump, and effectively avoids the problem of water diversion pipes. The advantage of being blocked with the retreating water pipe is to solve the problem of high construction and site requirements caused by multiple retreating water outlets, increasing the difficulty of cost and construction coordination, and at the same time, the retreating water is easily blocked by garbage and silt in the sewage pipe

[0005] In order to achieve the purpose of small footprint, low construction difficulty, solve the existing problem of sewage water point spacing requirements, reduce the power consumption of the sewage lift pump, and effectively avoid the blockage of the water diversion pipe and the water return pipe, the present invention provides the following technical solutions : A kind of sewage utilization withdrawing water square culvert device, comprising a square culvert body, a first sewage pipe and a second sewage pipe are arranged near the left and right sides in the square culvert body, and the distance between the first sewage pipe and the second sewage pipe is A sealing mechanism is arranged between them, and the sealing mechanism includes a bearing seat, a screw rod, a ball nut and a sealing plate, and a bearing seat is fixedly installed on the upper surface of the square culvert body, and a screw rod is fixedly installed inside the bearing seat. A ball nut is arranged on the screw rod, and a sealing plate is fixedly installed on the lower surface of the ball nut, and the sealing plate seals the opposite side of the first sewage pipe and the second sewage pipe, and the front side of the first sewage pipe is opened There is a water withdrawal hole, and a water diversion hole is opened on the front side of the second sewage pipe, and a filter mechanism is provided on the front side of the water retreat hole and the water diversion hole, and the filter mechanism includes a filter box, a baffle plate, and a grid plate and a round hole, the filter box is fixedly installed on the front side of the first sewage pipe and the second sewage pipe, a baffle is fixedly installed between the inner walls of the filter box, and a grille plate is arranged on the upper side of the baffle, The front side of the filter box is provided with round holes, and the front side of the square culvert body on the front side of the round hole corresponding to the water withdrawal hole is provided with a water withdrawal pipe, and the front side of the square culvert body on the front side of the round hole corresponding to the water diversion hole is water pipe on the side
