Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mobile water-gas combined flushing device for a rainwater storage tank. Background Art

[0002] At present, rainwater storage tanks are widely used in many areas of my country as one of the methods to collect initial rainwater and solve urban water pollution problems. At the beginning of rainfall, rainwater storage tanks collect initial rainwater with a large amount of pollutants and store it for a short time. After the precipitation stops, this part of the initial rainwater is discharged into the urban sewage system, and finally discharged after being treated by the urban sewage treatment plant, thereby achieving the purpose of controlling rainwater pollution. Impurities in the initial rainwater will be deposited in the storage tank. Long-term deposition will form a layer of bottom mud that is difficult to remove, affecting the normal use function of the storage tank. Therefore, the storage tank needs to be effectively flushed after a single rainfall. At present, most storage tanks are built at a deep depth, and manual dredging is difficult and dangerous. Mechanical cleaning is generally used. At present, the jet flushing system is a more common mechanical cleaning method, but the jet flushing water pump is fixedly installed somewhere in the storage tank, and its rotation angle is limited, which limits the effective cleaning range of the storage tank and has certain requirements for the size of the storage tank. Therefore, there is an urgent need for a water-gas combined flushing device that can flexibly adjust the jet flushing position in the storage tank, increase the flushing range, and is suitable for use in a variety of rainwater storage tanks. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the above-mentioned prior art and to provide a water-gas combined flushing device which can flexibly adjust the jet flushing position in the storage tank, increase the flushing range and is suitable for use in a variety of rainwater storage tanks.

[0004] In order to achieve the above object, the utility model is implemented through the following technical solutions:

[0005] A mobile water-gas combined flushing device for a rainwater storage tank comprises a track, a mobile vehicle, a support frame and a flushing water pump, wherein the track is arranged on the top of the rainwater storage tank, the wheels of the mobile vehicle cooperate with the track, the support frame is fixedly arranged at the bottom end of the mobile vehicle between the tracks, and the flushing water pump is arranged at the bottom of the support frame; a vertical air intake pipe is fixedly arranged on the support frame, the top end of the air intake pipe is higher than the flushing liquid level of the rainwater storage tank, the bottom end of the air intake pipe is connected to the water outlet of the flushing water pump, and a flushing nozzle is also connected to the water outlet of the flushing water pump.

[0006] Furthermore, the flushing nozzle is a zigzag pipe, and the water outlet of the flushing nozzle is bent downward.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] During the movement of the mobile vehicle in the utility model, the flushing water pump can be driven to follow the movement, the position of the flushing water pump in the rainwater storage tank can be adjusted, the range of movement of the flushing water pump can be increased, and thus the flushing range can be increased. During the flushing process, air and rainwater simultaneously enter the flushing water pump and are then discharged outward, forming a water-air combined flushing form to impact and stir the bottom mud deposited in the storage tank, and the flushing effect on the impurities at the bottom of the rainwater storage tank is better. Moreover, the entire equipment only needs to be arranged on the top of the rainwater storage tank, occupying less space. The flushing water pump, air intake pipe and flushing nozzle can be set as a single unit or multiple units according to the width of the corridor of the rainwater storage tank, and has strong adaptability.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0015] like Figure 1 and Figure 2 As shown, a mobile water-gas combined flushing equipment for a rainwater storage tank comprises a track 2, a mobile vehicle 1, a support frame 4 and a flushing water pump 3, wherein the track 2 is arranged on the top of the rainwater storage tank 8, the wheels of the mobile vehicle 1 cooperate with the track 2, the support frame 4 is fixedly arranged at the bottom end of the mobile vehicle 1 between the tracks 2, and the flushing water pump 3 is arranged at the bottom of the support frame 4; a vertical air intake pipe 5 is fixedly arranged on the support frame 4, the top end of the air intake pipe 5 is higher than the flushing liquid level 7 of the rainwater storage tank 8, the bottom end of the air intake pipe 5 is connected to the water outlet of the flushing water pump 3, and a flushing nozzle 6 is also connected to the water outlet of the flushing water pump 3.

[0016] Among them, the flushing nozzle 6 is a zigzag pipe, and the water outlet of the flushing nozzle 6 is bent downward, which can be as close to the bottom of the rainwater storage tank 8 as possible, which is more conducive to impacting and stirring impurities such as solid particles deposited on the bottom of the tank, and discharging them from the storage tank along with the rainwater.

[0017] During the movement of the mobile vehicle 1 in the utility model, the flushing water pump 3 can be driven to follow the movement, adjust the position of the flushing water pump 3 in the rainwater storage tank 8, increase the range of movement of the flushing water pump 3, and thus increase the flushing range. When the rainwater storage tank 8 is in the water filling period, it is not necessary to fill the water for flushing. When the rainfall ends and the water level stored in the rainwater storage tank 8 reaches the flushing liquid level 7, the flushing water pump 3 is started. The flushing water pump 3 sucks the rainwater stored in the rainwater storage tank 8 and sprays the rainwater to the bottom of the tank through the flushing nozzle 6. In this process, through the Venturi tube principle, air is sucked into the air intake pipe 5, and then mixed with the rainwater discharged by the flushing water pump 3, and discharged through the flushing nozzle 6, forming a water-gas combined flushing form to impact and stir the bottom mud deposited in the rainwater storage tank 8. At the same time, the mobile vehicle 1 reciprocates on the track 2, so that the entire area within the longitudinal range of the rainwater storage tank 8 is effectively flushed, and the flushing liquid level 7 can be set to the highest liquid level of the rainwater storage tank 8, and can also be manually adjusted according to the operating conditions.

[0018] like Figure 3 As shown, the flushing water pump 3, the air intake pipe 5 and the flushing nozzle 6 can be provided in single or multiple units according to the width of the corridor of the rainwater storage tank, and have strong adaptability.

[0019] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
