Description

Technical Field

[0001] The utility model relates to the technical field of seal ring assembly, and particularly relates to an industrial wastewater centralized treatment system. Background Art

[0002] To protect the environment, industrial wastewater needs to be uniformly treated by evaporation equipment. However, the production lines that generate wastewater are widely distributed in this factory building, which brings certain troubles to the transportation of wastewater. Each time on the production line, the wastewater must be pumped into a special wastewater collection bucket by a water pump, and then manually pushed to the side of the wastewater professional treatment facility by a cart and a person. Then, the wastewater is pumped into the wastewater evaporation storage bucket by a water pump. Such a process of manual transportation of wastewater not only takes time but also requires corresponding personnel for transportation. It is time-consuming and laborious. One existing method is to first pump the sewage from the production line into a temporary storage tank. After the temporary storage tank is full, it is pumped into the evaporation tank. The evaporation tank is regularly opened to evaporate and concentrate the sewage in the pipe. In this mode, when there is only a small amount of sewage in the evaporation tank, it will still be regularly opened for treatment, resulting in waste of energy; when the temporary storage tank is full and the evaporation tank is under maintenance, production can only be stopped to stop sewage discharge, resulting in a reduction in production capacity. Therefore, the utility model proposes an industrial wastewater centralized treatment system. Content of the Utility Model

[0003] The main purpose of the utility model is to provide an industrial wastewater centralized treatment system, which can...

[0004] The utility model realizes the above purpose through the following technical scheme: An industrial wastewater centralized treatment system includes a temporary storage tank. The temporary storage tank is connected to a sewage discharge port through a pipeline and a water pump. The temporary storage tank is connected to an evaporation tank through a pipeline. A stop valve is provided between the evaporation tank and the temporary storage tank. The temporary storage tank is higher than the evaporation tank. A regulating valve assembly is connected to the pipeline between the evaporation tank and the temporary storage tank. When the liquid level in the evaporation tank is low, the regulating valve assembly is in an open state; when the liquid level in the evaporation tank is high, the regulating valve assembly is in a closed state.

[0005] Preferably, the regulating valve assembly includes a vertical pipe arranged at the top inside the evaporation tank. The vertical pipe is provided with an inner cavity, and the inner cavity is communicated with the temporary storage tank through a pipeline. A floating box is arranged inside the evaporation tank. A guide rod is vertically arranged inside the evaporation tank. The floating box is movably connected to the guide rod. A vertical rod penetrates through the floating box. The vertical rod is movably connected inside the vertical pipe. An opening is provided on the inner wall of the vertical pipe. A blind hole is coaxially arranged at the bottom end of the vertical rod. A water inlet communicating with the blind hole is provided on the circumferential surface of the vertical rod. When the regulating valve assembly is in an open state, the water inlet is directly opposite to the opening.

[0006] Preferably, the guide rod, the floating box and the vertical rod are all made of stainless steel.

[0007] Preferably, a plurality of the openings and the water inlets are correspondingly arranged.

[0008] The beneficial effects of the technical solution of the present utility model are as follows:

[0009] The temporary storage tank is higher than the evaporation tank, and the sewage flows from the temporary storage tank into the evaporation tank under the action of its own weight, without the need for an additional water pump for pumping, saving equipment costs and energy consumption;

[0010] When the sewage in the evaporation tank reaches the high liquid level, the regulating valve assembly closes, and the subsequent sewage is stored in the temporary storage tank. At this time, evaporating and concentrating the sewage in the evaporation tank can maximize the benefits. When the sewage in the evaporation tank drops to the low liquid level, the regulating valve assembly opens again, and the sewage stored in the temporary storage tank flows into the evaporation tank, so as to keep a relatively high liquid level in the evaporation tank and improve the treatment efficiency;

[0011] When the evaporation tank does not reach the high liquid level, the sewage entering the temporary storage tank preferentially flows into the evaporation pipe, so that a relatively large space is left in the temporary storage tank. When the evaporation tank needs to be maintained, the stop valve is closed, and the temporary storage tank is used to receive the sewage from the production line without shutting down the production line, thus ensuring the production capacity.

[0016] The present utility model will be further described in detail below in conjunction with specific embodiments.

[0017] Embodiment:

[0018] As Figure 1 and Figure 2As shown in the figure, an industrial wastewater centralized treatment system of the present utility model includes a temporary storage tank 1. The temporary storage tank 1 is connected to a sewage outlet through a pipeline and a water pump. The temporary storage tank 1 is connected to an evaporation tank 2 through a pipeline. A stop valve 3 is provided between the evaporation tank 2 and the temporary storage tank 1. The temporary storage tank 1 is higher than the evaporation tank 2. A regulating valve assembly is connected to the pipeline between the evaporation tank 2 and the temporary storage tank 1. When the liquid level in the evaporation tank 2 is low, the regulating valve assembly is in an open state; when the liquid level in the evaporation tank 2 is high, the regulating valve assembly is in a closed state. In the initial state, the liquid level in the evaporation tank 2 is low and the regulating valve assembly is in an open state. During production activities, the water pump pumps the sewage generated by the production line into the temporary storage tank 1. The stop valve 3 is in an open state all the time. The sewage flows from the temporary storage tank 1 into the evaporation tank 2 under the action of its own weight without the need for an additional water pump to pump water, saving equipment costs and energy consumption. When the sewage in the evaporation tank 2 reaches a high liquid level, the regulating valve assembly closes, and the subsequent sewage is stored in the temporary storage tank 1. At this time, evaporating and concentrating the sewage in the evaporation tank 2 can maximize the benefits. When the sewage level in the evaporation tank 2 drops to a low level, the regulating valve assembly opens again, and the sewage stored in the temporary storage tank 1 flows into the evaporation tank 2, so as to keep a relatively high liquid level in the evaporation tank 2 and improve the treatment efficiency.

[0019] The regulating valve assembly includes a vertical pipe 4 provided at the top inside the evaporation tank 2. The vertical pipe 4 is provided with an inner cavity 5. The inner cavity 5 is communicated with the temporary storage tank 1 through a pipeline. A floating box 6 is provided inside the evaporation tank 2. A guide rod 7 is vertically provided inside the evaporation tank 2. The floating box 6 is movably connected to the guide rod 7. A vertical rod 8 penetrates through the floating box 6. The vertical rod 8 is movably connected inside the vertical pipe 4. An opening 9 is provided on the inner wall of the vertical pipe 4. A blind hole 10 is coaxially provided at the bottom end of the vertical rod 8. A water inlet 11 communicating with the blind hole 10 is provided on the circumferential surface of the vertical rod 8. When the regulating valve assembly is in an open state, the water inlet 11 is aligned with the opening 9. Sewage enters the inner cavity 5 along the pipeline, then enters the blind hole 10 through the opening 9 and the water inlet 11 and flows into the evaporation tank 2. When the liquid level in the evaporation tank 2 reaches a high level, the floating box 6 drives the vertical rod 8 to rise, the water inlet 11 rises above the opening 9, and the circumferential surface of the vertical rod 8 blocks the opening 9. The sewage is temporarily stored in the temporary storage tank 1. When the liquid level in the evaporation tank 2 drops, the floating box 6 drives the vertical rod 8 downward, the opening 9 is opened, and the sewage stored in the temporary storage tank 1 flows into the evaporation tank 2.

[0020] The guide rod 7, the floating box 6 and the vertical rod 8 are all made of stainless steel.

[0021] A plurality of the openings 9 and the water inlets 11 are correspondingly arranged.

[0022] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the inventive concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model.
