Description

Technical Field

[0001] This utility model relates to the field of power plant wastewater treatment, specifically to a calcium hydroxide feeding hopper for power plant wastewater treatment. Background Technology

[0002] Power plant wastewater comes from a wide range of sources and can be mainly classified into the following categories: ash flushing wastewater, desulfurization wastewater, and industrial wastewater. Adding sodium hydroxide to wastewater can reduce water hardness through a neutralization reaction. A search revealed existing technology (application number: 201921654770.2), which describes a process where "as the feeding vessel travels on the wastewater surface, the bottom of the storage hopper can intermittently feed material into the wastewater, ensuring uniform feeding. Furthermore, the feeding vessel's movement can be controlled by whether the insertion rod engages with the circular trough to determine whether feeding is being carried out into the wastewater."

[0003] However, in the existing technology, it is difficult for employees to operate the feeding boat to move, which may cause the boat to tilt to one side and may cause employees to fall into the sewage treatment pond. This also makes it difficult to safely and conveniently add calcium hydroxide to the hopper. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a calcium hydroxide feeding hopper for power plant wastewater treatment is provided. This solves the problem that in existing technologies, it is difficult for employees to operate the feeding boat, which may cause it to tilt and potentially fall into the wastewater treatment pond. This makes it difficult to safely and conveniently feed calcium hydroxide into the hopper.

[0005] To achieve the above objectives, a calcium hydroxide feeding hopper for power plant wastewater treatment is provided, comprising: a feeding base placed on the water surface of a power plant wastewater treatment pond, and a feeding bucket filled with calcium hydroxide granules.

[0006] A floating ring is fixedly bonded to the lower end face of the feeding base. The feeding base is connected to a lead screw via a stepper motor. The lead screw is fixedly connected to a feeding bucket via a movable base plate. The lower end of the feeding bucket is connected to a discharge port via a conveying pipe. The discharge port is located at the lower end of the floating ring.

[0007] Furthermore, a waterproof box is screwed to the upper surface of the feeding base, and a controller is fixed inside the waterproof box; and the controller is wired to a stepper motor.

[0008] Furthermore, a stepper motor is fixed inside the left side of the feeding base, and the stepper motor is connected to a lead screw through a rotating shaft, with a drive block connected to the surface of the lead screw.

[0009] Furthermore, a connecting ring block is welded to the upper surface of the feeding base; and a rope is tied to the surface of the connecting ring block, and an electric valve is installed on the surface of the conveying pipe.

[0010] Furthermore, a sealing cap is screwed to the upper end of the feeding hopper, and a feeding trough is provided inside the feeding base; and a conveying pipe runs through the feeding trough.

[0011] Furthermore, a movable base plate is welded to the lower end of the feeding hopper, and a fixed block is welded to the lower end of the movable base plate; and the lower end of the fixed block is fixed to the driving block.

[0012] Furthermore, the lower end of the movable base plate contacts the upper surface of the feeding base via ball bearings, and the inner groove wall of the feeding base is connected to a lead screw via bearings.

[0013] The beneficial effects of this utility model are that the calcium hydroxide feeding hopper for power plant wastewater treatment utilizes a floating ring to float the entire hopper on the surface of the wastewater treatment pond, making it convenient for the feeding hopper to be placed horizontally on the wastewater surface. This allows employees to safely move the hopper from the shore of the wastewater treatment pond. A stepper motor drives the feeding bucket connected to the upper end to move left and right, so that the feeding bucket evenly dispenses the calcium hydroxide inside into the wastewater treatment pond, making the calcium hydroxide dispensing more uniform and facilitating safe and convenient calcium hydroxide dispensing.

The discharge port 32 is located at the lower end of the floating ring 2.

[0022] Working principle: Place the feeding base 1 on the water surface of the power plant wastewater treatment pond, start the stepper motor 4 to move the feeding bucket 3 left and right, and at the same time open the electric valve 34 to put the calcium hydroxide granules into the power plant wastewater treatment pond. Then pull the feeding base 1 to move horizontally, so that the feeding base 1 is slowly moved on the water surface of the power plant wastewater treatment pond to feed the material.

[0023] In this embodiment, a waterproof box 12 is screwed to the upper surface of the feeding base 1, and a controller 13 is fixed inside the waterproof box 12; and the controller 13 is wired to a stepper motor 4.

[0024] As a preferred embodiment, the waterproof housing 12 prevents the controller 13 from getting wet. The controller 13 controls the stepper motor 4 to rotate, and simultaneously controls the opening and closing of the electric valve 34.

[0025] In this embodiment, a stepper motor 4 is fixed inside the left side of the feeding base 1. The stepper motor 4 is connected to a lead screw 42 through a rotating shaft 41. A drive block 43 is connected to the surface of the lead screw 42.

[0026] In a preferred embodiment, the stepper motor 4 drives the lead screw 41 to rotate via the rotating shaft 41, so that the drive block 43 on the surface of the rotating shaft 41 drives the feeding bucket 3 at the upper end of the movable base plate 5 to move left and right to feed materials.

[0027] In this embodiment, a connecting ring block 11 is welded to the upper surface of the feeding base 1; and a rope is tied to the surface of the connecting ring block 11, and an electric valve 34 is installed on the surface of the conveying pipe 33.
