Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

In order to solve the technical problem of how to realize the treatment of the aeration tank foam under the condition of low power consumption, as shown in figures 1-4:

a foam treatment device of a large sewage treatment aeration tank comprises an outer bin 1, a partition plate 2, a lifting mechanism 3, a filtering mechanism 4, a drainage mechanism 5, an induction mechanism 6, a changing mechanism 7 and a moving mechanism 8; the housing includes a heightened plate 1 a; the lifting mechanism 3 comprises a screw rod 3a, a first rotary driver 3b, a first slide block 3c, a second slide block 3d, a baffle 3e and a chute 3 f; the first rotary driver 3b is arranged at the top of the outer bin 1, and the output end of the first rotary driver 3b points to the bottom of the outer bin 1; two ends of the screw rod 3a are respectively and fixedly arranged on the output end of the first rotary driver 3b and the bottom of the outer bin 1; the first sliding block 3c is arranged on the screw rod 3a in a sliding way; the sliding chute 3f is arranged on the side wall of the outer bin 1 along the height direction of the outer bin 1; the second sliding block 3d is slidably arranged on the sliding groove 3f, and the second sliding block 3d is fixedly connected with the first sliding block 3 c; the stop block is fixedly arranged at one end of the second slide block 3d far away from the first slide block 3 c.

Based on the above embodiment, the first rotary driver 3b of the present application is preferably a servo motor, the outer bin 1 is disposed in the aeration tank along the width direction of the aeration tank, and the length direction of the outer bin 1 is equal to the width of the aeration tank. The setting of baffle 2 symmetry is in the inside in outer storehouse 1, and the length direction of baffle 2 is parallel with the length direction in outer storehouse 1, and there is certain clearance baffle 2 and the lateral wall in outer storehouse 1, and elevating system 3 sets up on the clearance between baffle 2 and the lateral wall in outer storehouse 1, and first slider 3c sets up in the clearance. The terminal surface coplane at the top in baffle 2 and the 1 top in outer storehouse, the stopper is fixed to be set up at the top in baffle 2 and outer storehouse 1, and the effect of stopper prevents that first slider 3c from lifting too high under the drive of lead screw 3a to the condition of roll-off spout 3f takes place. The filtering mechanism 4 is arranged inside the outer bin 1, and the filtering mechanism 4 is used for separating and filtering the foam from the water. The drainage mechanism 5 is arranged on the outer bin 1 below the filtering mechanism 4, and the drainage mechanism 5 is used for draining the water filtered by the filtering mechanism 4 into the ash aeration tank. The induction mechanism 6 is arranged on the outer bin 1 and the stop block, and the induction mechanism 6 is used for monitoring the water level so as to control the lifting mechanism 3 to lift. The reloading mechanism 7 is arranged above the filtering mechanism 4, and the reloading mechanism 7 is used for helping workers to reload the filtering mechanism 4. The moving mechanism 8 is arranged on the reloading mechanism 7, and the moving mechanism 8 can drive the reloading mechanism 7 to move. The specific flow is as follows, in the initial state, the baffle 3e is higher than the water level in the aeration tank, and the initial state is the state when the upper part of the first slide block 3c is not contacted with the limiting block. At this time, the water in the aeration tank cannot flow into the outer bin 1. At this moment, the sensing mechanism 6 senses that the water level of the aeration tank is lower than the baffle 3e, so that the first rotary driver 3b rotates, the first rotary driver 3b can drive the first sliding block 3c and the second sliding block 3d to gradually descend along the sliding groove 3f, and when the sensing mechanism 6 senses that the water level of the aeration tank is flush with the top of the baffle 3e, only a little downward descending is needed. So that the water on the upper surface of the aeration tank can flow into the outer bin 1. The inflowing water flow can drive the foam floating above the water flow to flow into the outer bin 1 together, then the inflowing water and the foam can be filtered by the filtering mechanism 4, the foam can be blocked by the filtering mechanism 4, and the water can fall to the bottom of the outer bin 1 from the filtering mechanism 4 and be discharged by the drainage mechanism 5. The foam is discharged by the filter means 4. When the filtering mechanism 4 is used for a period of time, the filtering mechanism needs to be replaced, the boiler mechanism can be replaced only by hoisting and moving the boiler mechanism through the replacing mechanism 7 and the moving mechanism 8, and after the replacing is completed, the filtering mechanism 4 is hoisted back to the outer bin 1 again. Thus, the foam in the aeration tank can be treated under the condition of low power consumption.

Further, in order to solve the technical problem of how the filtering device separates the foam from the water, as shown in fig. 4 to 6:

the filtering mechanism 4 comprises a filtering plate 4a, a first stop block 4b, a second stop block 4c and a foam outlet 4 d; the first stop block 4b is fixedly arranged on the side wall of the outer bin 1; the second stop block 4c is fixedly arranged on the side wall of the outer bin 1 opposite to the first stop block 4 b; the filter plate 4a is arranged on the first stop 4b and the second stop 4 c; the foam outlet 4d is opened on the side wall of the outer bin 1 provided with the second stopper 4 c.

Based on the above embodiment, the first stopper 4b of the present application has a height higher than that of the second stopper 4c, and the second stopper 4c is disposed below the foam outlet 4 d. The filter plate 4a is obliquely disposed on the first stopper 4b and the second stopper 4c, and an end of the filter plate 4a positioned at the second stopper 4c should be higher than the bottom of the foam outlet 4d, so that the foam flowing in from the aeration tank can better flow down from the filter plate 4a and be discharged from the foam outlet 4 d. The setting of filter 4a slope is for foam and water on falling filter 4a back, and water can not be filtered by filter 4a at once, but can flow according to the filtration, and this moment because the slope setting of filter 4a makes the rivers that flow drive the foam and remove to foam export 4 d. In the flowing process, the water flow is filtered by the filter plate 4a, and the foam is driven by a small amount of water flow to be discharged, so that the technical requirement of separating the foam from the water is met, and the problem is solved.

Further, in order to solve the technical problem of how to discharge the filtered water back to the aeration tank, as shown in fig. 4-5:

the drainage mechanism 5 comprises a water pump 5a, a first drainage hole 5b and a second drainage hole 5 c; the water pump 5a is arranged at the bottom of the outer bin 1; the first drainage hole 5b is arranged on the clapboard 2 along the outlet axis of the water pump 5 a; the second drain hole 5c is opened on the side wall of the outer bin 1 along the axis of the first drain hole 5 b.

Based on the above embodiments, the water pump 5a of the present application will start to operate continuously after the device starts to operate. This is because the water level in the outer bin 1 is continuously raised if not eliminated because the water and the foam in the aeration tank are continuously flushed into the inner part of the outer bin 1, so that the filter plates 4a cannot perform filtering. Because the partition board 2 and the side wall of the outer bin 1 have a gap, a drainage pipe is arranged between the first drainage hole 5b and the second drainage hole 5c, so that the water pump 5a can well discharge the water flow in the outer bin 1. Because the device is arranged in the aeration tank in a crossing way, the first drain hole 5b and the second drain hole 5c are symmetrically arranged, so that the water levels of the aeration tank at two sides of the outer bin 1 can be ensured to be basically the same. Therefore, the technical requirement of discharging the filtered water back to the aeration tank is met, and the problems are solved.

Further, in order to solve the technical problem of how the sensing mechanism 6 detects the position relationship between the baffle 3e and the water level of the aeration tank, as shown in fig. 3:

the sensing mechanism 6 includes a first water level sensor 6a, a second water level sensor 6b and a third water level sensor 6 c; the first water level sensor 6a is fixedly arranged at the top of the baffle plate 3 e; the second water level sensor 6b is arranged at the lower position of the side wall of the baffle plate 3 e; the third water level sensor 6c is provided at an upper position of a sidewall of the barrier 3 e.

Based on the above embodiment, the second water level sensor 6b of the present application is used to detect the lowest water level in the aeration tank, because the baffle 3e is lifted to the highest position in the initial state, and the height of the second water level sensor 6b is the same as the height of the top of the outer bin 1, if the second water level sensor 6b can receive the signal, the water level in the aeration tank is at the water level that can flow into the outer bin 1. If not, it indicates that filtering is not possible. Water needs to be added. The third water level sensor 6c is used for sensing whether the position of the side wall of the baffle 3e is higher or not to contact with water in the descending process of the baffle 3e, when the baffle 3e is not contacted with water, the descending speed of the baffle 3e is faster, when the baffle 3e is contacted with water, the descending speed of the baffle 3e is slowed down, when the first water level sensor 6a senses water flow, the baffle stops descending, the height of the baffle 3e is just lower than the height of the water surface of the aeration tank, and therefore the problem is solved.

Further, in order to solve the technical problem of how the filter plate 4a is replaced by the replacing mechanism 7, as shown in fig. 1 and 7:

the replacing mechanism 7 comprises a rope 7a, a rope winding wheel 7b, a first synchronous wheel 7c, a second synchronous wheel 7d, a synchronous belt 7e, a second rotary driver 7f, a top plate 7g and a supporting mechanism 7 h; the top plate 7g is arranged at the upper end of the outer bin 1; the ropes 7a are respectively fixedly arranged at four corners of the filter plate 4 a; the rope collecting wheel 7b is fixedly arranged at one end of the rope 7a far away from the filter plate 4 a; the first synchronizing wheel 7c is fixedly arranged on the rope winding wheel 7b along the axis of the rope winding wheel 7 b; the second synchronizing wheel 7d is fixedly arranged on the rope take-up wheel 7b along the axis of the rope take-up wheel 7b far away from the first synchronizing wheel 7 c; two ends of the synchronizing wheel are respectively arranged on the first synchronizing wheel 7c and the second synchronizing wheel 7 d; the second rotary driver 7f is fixedly arranged at the upper part of the top plate 7g, and the output end of the second rotary driver 7f is fixedly connected with the first synchronous wheel 7 c; the support mechanism 7h is provided on the top plate 7g on the second synchronizing wheel 7d side.

Based on the above embodiment, the second rotary driver 7f is preferably a servo motor, and when the second rotary driver 7f starts to rotate, the first synchronous wheel 7c is driven to rotate, and the second synchronous wheel 7d is driven to rotate through the synchronous belt 7e, so that the rope collecting wheel 7b rotates, and thus the lifting and replacing of the filter plate 4a are realized, and the above problem is solved.

Further, in order to solve the technical problem of how to support the second synchronizing wheel 7d, as shown in fig. 7:

the supporting mechanism 7h comprises a supporting piece 7h1 and a connecting shaft 7h 2; the support 7h1 is fixedly provided on the upper portion of the top plate 7 g; the connecting shaft 7h2 is fixedly provided on the support 7h1 along the axis of the second synchronizing wheel 7 d.

Based on the above embodiments, the second synchronizing wheel 7d of the present application is symmetrically disposed on the connecting shaft 7h2, and the second synchronizing wheel 7d is rotatably disposed on the connecting shaft 7h2, thereby solving the above problems.

The above examples only show one or more embodiments of the present invention, and the description is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
