Description

Technical Field

[0001] This utility model pertains to wastewater treatment devices, specifically a centrifugal industrial wastewater concentration and solidification device. Background Technology

[0002] Industrial production processes generate large amounts of industrial wastewater containing high concentrations of pollutants, suspended particles, or soluble substances. Direct discharge of this wastewater not only severely pollutes water bodies and soil but also wastes recyclable resources within it. Therefore, concentrating industrial wastewater is a crucial step in its resource recovery and reduction.

[0003] Currently, industrial wastewater concentration technologies mainly include evaporation concentration, membrane filtration concentration, and centrifugal concentration. Among these, centrifugal concentration technology is widely used in industrial wastewater treatment due to its advantages such as high treatment efficiency and relatively low energy consumption. However, existing centrifugal wastewater concentration devices have some shortcomings in actual operation:

[0004] Poor continuity: Most units need to be shut down for unloading or cleaning after one concentration cycle, which makes continuous operation impossible and limits processing efficiency.

[0005] Mutual interference: In some multi-filter cartridge centrifuges, the operation, feeding, and discharging of each filter cartridge are subject to linkage restrictions. When one filter cartridge is being maintained or operated, it will affect the normal operation of other filter cartridges, reducing the overall utilization rate of the equipment.

[0006] Complex operation: The feeding control of the filter cartridge, the discharge of the concentrate after centrifugation, and the cleaning of the filter residue often require manual assistance or complex mechanical linkages, which increases the difficulty of operation and labor costs.

[0007] Therefore, developing a centrifugal industrial wastewater concentration and solidification device that can achieve continuous operation, independent operation of each filter cartridge without interference, high degree of automation and easy use has become a key requirement to overcome the shortcomings of existing technologies. Utility Model Content

[0008] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a centrifugal industrial wastewater concentration and solidification device to solve the problems mentioned in the background art.

[0009] The technical solution adopted by this centrifugal industrial wastewater concentration and solidification device to solve its technical problems is as follows:

[0010] A centrifugal industrial wastewater concentration and solidification device is provided, comprising a housing containing several centrifugal filter cartridges. The bottoms of the centrifugal filter cartridges are rotatably mounted on the housing via bearings. Each centrifugal filter cartridge is square. A first piston is installed inside each centrifugal filter cartridge. A piston cylinder is located above each centrifugal filter cartridge and is fixedly mounted on the housing via a bracket. A second piston is installed inside each piston cylinder. A vertical rod is fixedly mounted on the bottom side of each second piston. The lower end of the vertical rod is rotatably connected to the first piston via a sealed bearing. A passage is provided on each second piston, extending along the vertical rod to the bottom of the first piston. The centrifugal filter cartridge has a hole and a through hole, each with a first electric valve fixedly installed inside. A water pump is fixedly installed on the piston cylinder, and the water pump is connected to the inside of the piston cylinder. A fixing ring is fixedly installed on the outer circumference of the centrifugal filter cartridge, and a gear ring is fixedly installed on the fixing ring. A motor is fixedly installed in the middle of the box through a bracket, and a gear is fixedly installed on the motor. The gear meshes with each gear ring. An electric telescopic rod is fixedly installed on the bottom side of the inner wall of the centrifugal filter cartridge. Drainage holes are opened at the bottom of the centrifugal filter cartridge, and drainage pipes are rotatably installed through sealed bearings. The drainage pipes pass through the bottom of the box. A drain hole is provided on one side of the box.

[0011] Furthermore, a one-way valve is provided at the connection between the water pump and the piston cylinder.

[0012] Furthermore, a second electric valve is provided on each of the drain pipes.

[0013] Furthermore, support plates are fixedly installed at the upper end of the electric telescopic rod.

[0014] Furthermore, contact switches are fixedly installed on the support plate.

[0015] Furthermore, a control panel is fixedly installed on one side of the enclosure. The control panel contains a PLC controller, which is connected to the first electric valve, water pump, motor, electric telescopic rod, second electric valve, and contact switch via circuits.

[0016] Furthermore, support legs are fixedly installed at the bottom of the box.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model illustrates a centrifugal industrial wastewater concentration and solidification device. In use, the water pump, connected to the wastewater tank, injects wastewater into the piston cylinder. Simultaneously, the motor starts, driving the centrifugal filter cylinder to rotate via gears and a gear ring. During rotation, the first piston descends, centrifuging and filtering out the water from the wastewater, which enters the tank and exits through the drain hole. The pump stops when the first piston contacts the electric telescopic rod, and the concentrated wastewater is discharged through the drain pipe. The pump then restarts, the first electric valve opens, and the electric telescopic rod extends, pushing the first piston upward to fill the centrifugal filter cylinder with water from the piston cylinder. The process continues until the electric telescopic rod reaches its maximum extension and retracts, closing the first electric valve. This process can be repeated for further wastewater concentration. The concentrated wastewater can then be transferred and solidified. This device facilitates wastewater concentration, and the centrifugal filter cylinders do not interfere with each other during continuous operation, making it more convenient to use.

[0019] 2. The centrifugal industrial wastewater concentration and solidification device of this utility model can prevent backflow of wastewater at the flushing pump through a one-way valve.

[0020] 3. The centrifugal industrial wastewater concentration and solidification device of this utility model can conveniently control the discharge through a second electric valve.

[0021] 4. The centrifugal industrial wastewater concentration and solidification device of this utility model can expand the force-bearing area through the support plate, making the pushing more stable.

[0022] 5. The centrifugal industrial wastewater concentration and solidification device of this utility model can better control the interior of each centrifugal filter cartridge by means of a contact switch and the contact between the second piston and the contact switch. In addition, the contact switch retracts into the support plate when subjected to force, so it will not affect the support of the support plate.

[0023] 6. The centrifugal industrial wastewater concentration and solidification device of this utility model allows the PLC controller to be configured via the control panel, facilitating the continuous operation of the device by the PLC controller.

[0024] 7. The centrifugal industrial wastewater concentration and solidification device of this utility model can easily support the box and elevate the centrifugal filter cylinder through the support legs. Attached Figure Description
