Description

Technical Field

[0001] The utility model belongs to the field of filter material replacement devices, and in particular relates to a filter material replacement device for industrial wastewater treatment. Background Art

[0002] With the development of my country's nuclear industry, a large amount of radioactive waste has been generated, a large part of which is radioactive wastewater. Radioactive wastewater can be treated by adsorption, ion exchange, evaporation, flocculation and sedimentation, etc. When the adsorption and ion exchange methods use water treatment materials such as zeolite, activated carbon, and ion exchange resin, the wastewater flow can easily break these materials. Therefore, in the radioactive wastewater treatment process, these materials are usually loaded into filter bags to facilitate loading and unloading of filter materials, and the filter materials in the filter bags are generally not filled, so that after the filter bags are placed in the wastewater treatment barrel, the filter bags are horizontally stretched and fit the side of the wastewater treatment barrel.

[0003] A Chinese patent with announcement number CN212434268U discloses a radioactive industrial wastewater filter material replacement device, which relates to the technical field of radioactive wastewater treatment, and includes a box body, a fixed plate is fixedly connected to the bottom end of one side of the box body, a motor is fixedly installed on the upper surface of the fixed plate, an electric push rod is provided on the lower surface of the box body, a manipulator is fixedly installed on the bottom end of the electric push rod, a rotating shaft is fixedly connected to the output end of the motor, one end of the rotating shaft extends into the installation cavity provided in the box body, one end of the rotating shaft located in the box body is fixedly connected to a screw rod, a movable block is provided on the screw rod, and a slider is fixedly connected to the middle part of the upper surface of the movable block. The utility model is convenient for rapid material replacement, has a reasonable structural design, a simple operation process, a high degree of automation, and improves the material replacement efficiency. The radioactive industrial wastewater filter material replacement device in the application places the filter bag into the wastewater treatment barrel by a manipulator. After the filter bag has been used in the wastewater treatment barrel for a period of time, it is affected by the water flow, and the bundle end of the filter bag may move to an eccentric position in the wastewater treatment barrel. The manipulator that moves horizontally in a straight line may not be able to grasp the bundle end of the filter bag, and directly grasps the filter bag and pulls it out, which easily causes the filter bag to be damaged.

[0004] In view of this, the present utility model is proposed. Utility Model Content

The threads at both ends of the bidirectional threaded rod are in opposite directions, and the two ends of the bidirectional threaded rod are respectively matched with two T-shaped protruding threads, so that the first servo motor drives the bidirectional threaded rod to drive the clamping jaws and the arc-shaped push bar to move horizontally on the upper side of the filter bag, and the arc-shaped push bar pushes the filter bag bundle mouth at the eccentric part of the wastewater treatment barrel between the two clamping jaws.

[0010] Optionally, two bearing seats are provided in the first T-shaped groove, bearings are provided in the bearing seats, smooth curved surfaces are provided on the outer sides of both ends of the bidirectional threaded rod, and the two ends of the bidirectional threaded rod are respectively fixed in the two bearings, so as to improve the rotation stability of the bidirectional threaded rod through the bearings.

The driving mechanism is then turned on to drive the clamping claw and the arc-shaped push bar to move horizontally on the upper side of the filter bag. The arc-shaped push bar pushes the filter bag bundle at the eccentric part of the wastewater treatment barrel between the two clamping claws, so that the two clamping claws clamp the filter bag bundle at the filter bag bundle to lift out the filter material, thereby reducing the probability of directly grabbing the filter bag and causing the filter bag to be damaged.
