After a period of time, a large amount of sludge is deposited at the bottom of the sedimentation tank and needs to be cleaned, and the current common cleaning method comprises the following steps: stopping the car washing operation, discharging the water in the sedimentation tank, moving out a water pump or a bottom valve and other components in the tank, then removing the sludge at the bottom of the tank by manpower or an excavator, then reloading the water pump or the bottom valve, and starting the car washing operation after adding water. Due to the heavy work, some automatic mud discharging devices and technologies are recently introduced, such as an auger type mud discharging device disclosed in chinese patent CN201320506786.5 and a chain plate type mud discharging device disclosed in chinese patent CN201520053777.4, and these existing mud discharging devices have large floor area, poor effect, complex structure, high price and troublesome maintenance, and the car washing operation must be stopped during the mud discharging operation, so that the application is not widely used.

Disclosure of Invention

The utility model aims at providing a rational in infrastructure automatic mud discharging device for service rack.

In order to achieve the purpose, the utility model is implemented according to the following technical scheme: an automatic sludge discharge device for a car washing platform comprises a sedimentation tank and a sludge tank arranged side by side with the sedimentation tank, wherein a high-level water tank is arranged on a partition wall between the sedimentation tank and the sludge tank; the sedimentation tank bottom is the toper end or the inclined plane end, the bottom of sedimentation tank bottom is provided with the sludge pump, and the sludge pump water inlet is provided with the filter screen, and the sludge pump delivery port passes through the lower part of preceding pipeline intercommunication high flush tank, and high flush tank upper portion is provided with the wash port, and the wash port leads to mud pond upper portion through the back pipeline, and the pipeline that the back pipeline end was sealed and was above that is provided with a plurality of apopores, mud pond upper portion is equipped with the overflow mouth and leads to the sedimentation tank.

Preferably, the control of the sludge pump is intermittently operated by using a time relay.

The working principle of this application does: the mud is enriched at the bottom of the sedimentation tank, and the mud pump pumps the denser mud water at the bottom of the sedimentation tank into the mud tank, and when the mud pump is selected, the flow of the mud pump is far smaller than that of car washing water of a car washing platform, so that the sedimentation effect of the dense mud water in the mud tank is far greater than that of the sedimentation tank, and the dense mud water can be well sedimentated at the sedimentation tank; the clear water at the upper part generated after the sedimentation in the mud pit returns to the sedimentation tank through an overflow port; the water inlet of the sludge pump is provided with the filter screen, so that large foreign matters such as branches, plastic cloth, leaves and the like carried by sewage can be filtered, and the sludge pump is prevented from being blocked; the time relay who sets up for set up the start-stop time period of sludge pump, wherein preferred setting scheme is: turn on for 10 seconds and stop for 20 seconds. The pump stopping time is set to adjust the sewage discharge flow (the total flow is large if the on time is long and the off time is short and vice versa) on the one hand, and on the other hand, the sewage in the front pipeline and the high-level water tank can form backflow when the pump is stopped, so that the water in the high-level water tank can play a role in backwashing the filter screen, and impurities attached to the filter screen can be flushed away in time to avoid or reduce the blocking phenomenon. The outlet of the rear pipeline is provided with a plurality of water discharging hole structures so as to reduce the disturbance effect of the discharged water on the mud pit, and the water discharging hole is positioned above the liquid level of the mud pit so as to facilitate the observation of whether the work is normal or not. Generally, whether the mud pit needs to be cleaned can be judged by observing the clarity degree of overflow water at the overflow port, and when the water at the overflow port becomes turbid, the mud pit is cleaned.

When the mud pit is cleaned, the car washing operation does not need to be stopped, the mud in the mud pit is dug out by the excavator which is frequently prepared in the construction site, the cleaning work is not necessarily thorough, and usually, the bottom of the mud pit is dug into one bucket or two buckets, so that the cleaning is very convenient.

The current other automatic mud device of arranging of contrast, when the car washer worked, arrange the mud device and can not move simultaneously, otherwise strong stirring effect can make the sedimentation tank can't play the precipitation, and mud also can't be sent out, and they are the shutdown state usually, only when mud deposits to a certain extent, stop the car washing operation and take out the moisture in the sedimentation tank and just can begin to arrange mud. Therefore, sludge is deposited at the bottom of the sedimentation tank in a normal state, and the sludge inevitably pollutes circulating water and makes the circulating water dirty because the water flow is large when the car washing platform operates. The device can work at any time (including car washing), so that the sewage accumulated at the bottom of the sedimentation tank can be discharged into the mud tank in time, and the circulating water becomes much clean.

Compared with the prior art, the beneficial effects of the utility model are that: 1. the structure is simple and reasonable, and the cost is low; 2. the operation is simple and the maintenance is convenient; 3. the car washing operation is not influenced, and the on-line mud cleaning can be realized; 4. the circulating water of the sedimentation tank is clean and clear.
