Problems solved by technology
If the stored rainwater is stored for a long time, a large amount of organic waste accumulated at the bottom of the storage tank will rot and ferment, which will seriously pollute the water quality, and then make the rainwater black and smelly. The excessive reproduction of bacteria will prevent the rainwater stored in the storage tank from being stored and utilized for a long time.

Embodiment Construction
[0025] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.
[0026] figure 1 Shown is an embodiment of a mud discharge valve with automatic adjustment of the size of the valve port proposed by the present invention. The mud discharge valve includes a water tank body 1, an air vent 2, a water inlet 3, a water inlet chamber 4, and a grid. Grid 5, grid comb 6, exhaust pipe 7, hinge seat 8, hinge shaft 9, mud discharge gate 10, mud discharge channel 11, outlet velocity sensing chamber 12, one-way valve 13, mud discharge port 14.
[0027] The water tank body 1 is hingedly connected with the hinged seat 8 through the hinged shaft 9, and the hinged seat 8 is fixedly connected with the foundation at the bottom of the storage tank, and the water tank body 1 rotates freely around the hinged shaft 9 to realize the opening and closing of the mud discharge valve.
[0028] The air vent 2 is set on the top of the wate...

A one-way valve comprises a valve bonnet rotating shaft, a one-way valve bonnet, a floating ball rotating shaft, a valve bonnet floating ball, a valve bonnet lock hook, a lock shaft and a one-way valve body. The one-way valve body is connected to the lower end of a water tank, the one-way valve bonnet and the one-way valve body are connected through the valve bonnet rotating shaft, and the one-way valve bonnet freely rotates around the valve bonnet rotating shaft. The valve bonnet lock hook and the valve bonnet floating ball are fixedly connected into a whole and are connected with the one-way valve bonnet through the floating ball rotating shaft. The lock shaft is fixedly connected to the one-way valve body, and the valve bonnet floating ball assists the one-way valve bonnet in opening and closing through the buoyancy of water in an outlet flowing speed sensing cavity. The invention further provides a mud valve device provided with the one-way valve and capable of automatically adjusting the size of a valve port. The water tank is hinged to a hinging seat through a hinging shaft, the hinging seat is fixedly connected to a bottom foundation of a regulating and storing pool, and the water tank freely rotates around the hinging shaft to achieve opening and closing of a mud valve. The one-way valve and the mud valve device have the characteristics of being simple in structure, reliable in use, convenient to mount and low in cost, allowing parameters to be easy to adjust, facilitating universality of products and the like.
Description
technical field [0001] The invention belongs to the technical field of water treatment, and relates to rainwater collection, adjustment and utilization technology, in particular to a device for separation, control and treatment of rainwater collection sludge. technical background [0002] In the field of rainwater collection and treatment, rainwater storage tank technology has been widely used. At present, the operation of rainwater storage tanks at home and abroad is mainly to reduce flood peak waterlogging and relieve the pressure of sewage treatment plants to receive sewage. Part of the rainwater is collected during the rainfall period, and the collected rainwater is emptied soon after the rainstorm, and then the sludge at the bottom of the storage tank is removed. If the stored rainwater is stored for a long time, a large amount of organic waste accumulated at the bottom of the storage tank will rot and ferment, seriously polluting the water quality, which will turn the...
