Starting a motor, wherein the motor drives a cam, an incomplete gear and a driving plate to rotate through a motor shaft, the matching of the driving plate and a grooved wheel is 4:1, namely the driving plate rotates for a circle, the grooved wheel rotates for a quarter of a circle, the time for the driving plate to contact with the grooved wheel is within a quarter of the rotation of the driving plate, at the moment, the driving plate does not contact with the grooved wheel when the motor drives the driving plate to rotate for 135 degrees, so that the cross-shaped rotating disc and a lower tank body do not rotate, but the motor drives the cam to rotate, an inclined plane push rod is contacted with the outer side surface of the cam, the inclined plane push rod rotates for 135 degrees from the maximum stroke to the minimum stroke, so that the inclined plane push rod moves leftwards, the lower tank body and an inclined block move downwards, the upper tank; the motor continues to rotate 90 degrees, the cam is always in contact with the inclined plane push rod at the position with the minimum stroke, so the inclined plane push rod does not displace, the motor drives the driving plate to rotate 90 degrees, which is exactly 90 degrees that the driving plate is in contact with the grooved pulley, so the driving plate drives the grooved pulley to rotate 90 degrees, the grooved pulley drives the cross turntable to rotate 90 degrees through the transmission shaft, the cross turntable drives 4 lower tank bodies to rotate 90 degrees around a circle through the sliding support fixed with the cross turntable, so that the lower tank body filled with sludge is rotated out of the lower position of the upper tank body, the lower tank body not filled with sludge is rotated into the lower position of the upper tank body, the position of the upper tank body is set to be No. 1 position, the cross turntable rotates anticlockwise, and every 90 degrees anticlockwise sequentially comprises No.; the upper and lower tanks do not touch. At the moment, the motor continues to rotate for 135 degrees, the driving plate is not in contact with the grooved pulley in the 135-degree process, so the cross turntable does not displace, the motor drives the cam to rotate for 135 degrees, the contact side surface of the cam and the inclined plane push rod is gradually increased to the maximum stroke from the minimum stroke in the process, so the inclined plane push rod moves to the right, the lower tank body and the inclined block are jacked up through the inclined plane, the upper tank body and the lower tank body are in contact with each other, and then sewage and alum can be introduced into the upper tank body and the lower tank body to perform sewage. Meanwhile, the toothed part of the incomplete gear is only 1 in 36 minutes, in the process of rotating 135 degrees, in the last 10 degrees, the incomplete gear is meshed with a gear on the outer side of a lower turntable of a lower tank body, a motor drives the lower turntable to rotate for 10 degrees, a shutter switch on the bottom of the lower tank body is opened, and the motor stops rotating for a period of time after rotating 135 degrees, so that the bottom of the lower tank body is kept in an open state for a period of time, sludge in the lower tank body can flow downwards to a sludge storage tank, the water treatment in the lower tank body and the upper tank body at the No. 1 position is finished, the incomplete gear is disengaged from the gear after the motor is restarted, the upper turntable and the lower turntable of the lower tank body are reset due to a torsion spring, the shutter switch is closed, and the bottom of; this equipment has 4 lower jar bodies and 1 last jar body, carries out water injection, sewage treatment work and puts clear water to the tank storage at position No. 1, carries out mud secondary sedimentation work at position No. 2, puts mud to the storage mud pond at position No. 3, can carry out the maintenance work of the lower jar of body at position No. 4, and the work efficiency can be improved in the cooperation of mutually.
Because the volume proportion of the clear water that obtains is far more than the proportion of mud among the water purification process, so the frequency of draining the water of tank should be higher than the frequency of draining the mud of mud storage tank, and when the inside water storage of tank reached certain liquid level, the vertical push rod of the inside floating block of box because the water level rises jack-up for straight line push rod left part and inclined plane push rod contact, its right part and the contact of tank valve upper portion inclined plane.
When the water level of the water storage tank is too high, when the starting motor combines the upper tank body and the lower tank body, the cam pushes the inclined plane push rod to lift the lower tank body, the straight line push rod is pushed rightwards, the water storage tank valve is pushed upwards under the action of the inclined plane, water in the water storage tank can be discharged outwards, after water purification in the upper tank body and the lower tank body is completed, the lower tank body is lowered, and due to the gravity action of the water storage tank valve, the floating block, the vertical push rod, the straight line push rod and the water storage tank valve all descend to seal the water storage tank again.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
