Description

Technical Field

[0001] The utility model relates to the technical field of waste acid recovery, in particular to a waste acid concentration and recovery device. Background Art

[0002] Waste acid recovery refers to the recycling of large amounts of acidic waste liquid generated during industrial production. When the existing waste acid recovery device flocculates the waste acid, the flocculant and impurities inside the waste acid may flocculate above the filter screen, and it is very easy to be diverted to the concentration mechanism under the action of the outlet pipe, thereby affecting the recovery purity of the waste acid.

[0003] The publication (announcement) number is CN220265526U, which discloses a waste acid recovery device with strong sealing performance, and its technical solution includes: a flocculation box and a concentration box, one side of the flocculation box is connected to a concentration box through a circulation pipe near the bottom, a circulation pump is installed in the middle of the circulation pipe, a moving motor is installed on one side of the top plate of the flocculation box, the output shaft of the moving motor is installed with a screw, and the screw is arranged inside the flocculation box, and a batching box is installed on the side of the top of the flocculation box away from the moving motor through a feed pipe, and the feed pipe is arranged near the bottom of the flocculation box. A waste acid recovery device with strong sealing performance solves the problem that when the existing waste acid recovery device flocculates the waste acid, the flocculant and the impurities inside the waste acid may flocculate above the filter net, and it is very easy to divert to the concentration mechanism under the action of the outlet pipe, thereby affecting the recovery purity of the waste acid, reducing the impurity content inside the waste acid, thereby improving the recovery purity of the waste acid.

[0004] Although the above scheme avoids flocculation from entering the waste acid delivery pipeline, the flocculation is squeezed by the filter plate and easily blocks the sewage pipeline, and the filter plate is also easily blocked when squeezing the flocculation, which affects the waste acid separation effect. Therefore, we propose a waste acid concentration and recovery device. Utility Model Content

[0005] The main purpose of the utility model is to provide a waste acid concentration and recovery device, which solves the problem that flocculation is easily blocked by the filter plate when squeezed, and the filter plate is also easily blocked when squeezing the flocculation, affecting the waste acid separation effect.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions: a waste acid concentration and recovery device, including a flocculation barrel and a heating barrel, and also including: a disturbance and impurity removal unit and a mobilization and filtration unit arranged between the flocculation barrel and the heating barrel;

[0007] The disturbance and impurity removal unit includes an aggregate hopper, a vertical impurity removal pipe, a rotating rod, a driving motor, a disturbance cross plate, and a spiral blade. The aggregate hopper is fixedly arranged at the bottom end of the flocculation barrel. The vertical impurity removal pipe is fixedly arranged at the bottom end of the aggregate hopper. The rotating rod is movably arranged on the vertical central axis of the flocculation barrel and extends into the vertical impurity removal pipe. The driving motor is fixedly installed on the top surface of the flocculation barrel, and its output end is connected to the top end of the rotating rod. The disturbance cross plate is fixedly arranged on the outer peripheral surface of the rotating rod and is located inside the aggregate hopper. The spiral blade is wound around the outer peripheral surface of the rotating rod and is located inside the vertical impurity removal pipe. A pipe plug is arranged on the outer peripheral surface at the bottom end of the vertical impurity removal pipe.

[0008] The adjustment and filtration unit includes a circular brush plate, a servo motor, a lead screw, a flocculant input pipe, and a circular filter plate. The circular brush plate is fixedly arranged on the inner top surface of the flocculation barrel, and the rotating rod movably passes through the circular brush plate. A circular through hole is provided on the circular brush plate. The servo motor is fixedly installed on the top surface of the flocculation barrel. The lead screw is arranged at the output end of the servo motor and extends into the flocculation barrel, and the lead screw passes through the circular through hole. The flocculant input pipe is fixedly installed on the outer peripheral surface at the top end of the flocculation barrel. The circular filter plate is threadedly connected to the lead screw and is located below the circular brush plate, and the rotating rod movably passes through the circular filter plate.

[0009] Preferably, the lead screw and the rotating rod are arranged parallel to each other.

[0010] Preferably, an infusion pipe is arranged between the outer peripheral surface of the flocculation barrel and the top surface of the heating barrel, and a delivery pump is installed on the infusion pipe.

[0014] Compared with the prior art, the waste acid concentration and recovery device of the present utility model has the following beneficial effects:

[0015] 1. In the present utility model, by setting the disturbance and impurity removal unit, after the driving motor operates to drive the rotating rod to rotate, the disturbance cross plate fixedly arranged on the outer peripheral surface of the rotating rod and located inside the aggregate hopper can disturb and stir the waste acid and the flocculant. After the flocculated matter is extruded by the circular filter plate, it will aggregate through the aggregate hopper. When removing the flocculated matter, the pipe plug on the vertical impurity removal pipe is removed, and the spiral blade wound around the outer peripheral surface of the rotating rod and located inside the vertical impurity removal pipe can push and export the aggregated flocculated matter on the vertical impurity removal pipe to complete the removal.

The flexible operation of the equipment for transferring and unblocking the circular filter plate ensures the waste acid separation effect. BRIEF DESCRIPTION OF THE DRAWINGS
