When the sewage in the box body reaches a certain height, the push rod slides into the groove under the action of the floating block, and pushes the water stop valve into the inlet pipe to achieve the purpose of blocking the sewage in the inlet pipe. The liquid level control device includes:

[0006] A water stop pipe, the water stop pipe passes through the water inlet pipe and is fixedly connected to the water inlet pipe;

[0007] A control rod is fixedly connected to the inner wall of the box.

[0008] Preferably, the water stop pipe has a water stop valve slidably connected to the inner wall of the water stop pipe. The water stop valve is in the shape of a sphere, and the diameter of the sphere is the same as the diameter of the inner wall of the water inlet pipe. When the water level in the box rises, the push rod is driven to rise, and the water stop valve is pushed into the water inlet pipe to block the sewage in the water inlet pipe. The water stop pipe is provided with a slot, the diameter of the slot is consistent with the diameter of the push rod, and the position of the slot is directly above the push rod.

[0009] Preferably, the control rod is slidably connected to a slider, and the top of the slider is fixedly connected to a push rod for pushing the water stop valve into the water inlet pipe to block the sewage in the water inlet pipe from entering the box.

[0010] Preferably, the outer wall of the slider is fixedly connected with a slide rod, the slide rod is slidably connected with a slide groove, and the outer wall of the slider is fixedly connected with a floating block to provide buoyancy for the slider to float upward.

[0011] Preferably, the limit device is provided with a limit groove, and the setting of the limit groove makes the sliding of the limit rod more stable. The limit groove is slidably connected to the limit rod for limiting the sliding rod.

The outer wall of the turntable is fixedly connected to a rotating shaft, and the end of the rotating shaft away from the turntable passes through the box and is rotatably connected to the box.

[0013] Beneficial Effects

[0014] The utility model provides a sewage reaction tank with a liquid level control function. It has the following beneficial effects:

[0015] (1) In the sewage reaction tank with the liquid level control function, when the sewage in the tank is injected to a certain height, the push rod enters the water stop pipe through the slot under the buoyancy of the float and contacts and pushes the water stop valve. At this time, the water stop valve slides on the inner wall of the water stop pipe under the action of the push rod. When the sewage is injected to a specified height, the push rod pushes the water stop valve into the water inlet pipe to prevent the flow of sewage. This method can well control the amount of sewage injected into the tank and prevent excessive sewage from overflowing the reaction tank.

[0016] (2) In the sewage reaction tank with the liquid level control function, under the buoyancy of the float, the slide bar slides upward in the slide groove. When the slide bar slides to the specified height, the slide bar contacts and squeezes the limit rod, so that the limit rod continuously squeezes the spring, causing the spring to undergo elastic deformation and generate elastic force. When the slide bar slides over the limit rod, the limit rod re-pops out the support slide bar under the elastic force of the spring, and the support slide bar assists the water stop valve in blocking the sewage, thereby preventing the thrust of the push rod on the water stop valve from decreasing due to the drop in the sewage level in the reaction tank, thereby reducing the blocking effect of the water stop valve on the sewage.

When sewage is injected into the box body 1, the slider 521 slides in the control rod 52 under the buoyancy of the float block 524. When the sewage in the box body 1 is injected to a certain height, the push rod 523 enters into the water stop pipe 51 through the groove 512 under the action of the slider 521 and contacts the water stop valve 511. At this time, the water stop valve 511 slides on the inner wall of the water stop pipe 51 under the action of the push rod 523. When the sewage is injected to a specified height, the push rod 523 pushes the water stop valve 511 into the water inlet pipe 3 to block the flow of sewage.

When the sewage is injected to a specified height, the push rod 523 pushes the water stop valve 511. When the slider 521 slides to the specified height, the slide bar 522 contacts and squeezes the limit rod 42 to cause the spring 44 to elastically deform and generate an elastic force. When the slide bar 522 slides over the limit rod 42, the limit rod 42 pops out again under the elastic force of the spring 44 to support the slide bar 522.
