Description

Technical Field

[0001] The utility model relates to the technical field of fluoride removal in mine water treatment, and particularly relates to a fluoride addition and dosing device for a mine water treatment station. Background Technique

[0002] In the process of mine water treatment, during coal mining, the water in the underground mining space is transported to the surface water treatment station through a lifting pump for in-depth treatment. Since the original groundwater hydrogeological conditions are damaged during coal mining, water-rock interaction occurs in the water body, resulting in excessive fluoride in the mine water. According to the Class III water standard in the "Surface Water Environment Quality Standard" GB3838-2002, the fluoride content in mine water shall not exceed 1.0 mg / L. To achieve up-to-standard discharge, fluoride removal agents need to be added to control the fluoride content in mine water. Currently, solid powder fluoride removal agents are mainly used, which are stirred and mixed with water in a certain proportion and then added to the fluoride removal reaction tank through a pipeline mixer for fluoride removal.

[0003] During the actual operation process, due to the continuous change of the quality conditions of the original mine water, especially the fluoride content is affected by the mining geological conditions, resulting in unstable fluoride content in the incoming water. The dosing amount of the fluoride removal agent cannot be controlled in time. In order to quickly reduce the fluoride content, on-site personnel will manually sprinkle the fluoride removal agent in the reaction tank. Using the method of sprinkling the agent will cause environmental pollution on the one hand, and on the other hand, the agent is corrosive, posing a safety hazard. At the same time, the agent is not evenly sprinkled, resulting in excessive dosing of the agent and affecting the operation cost of the water treatment station.

[0004] Therefore, we propose a fluoride addition and dosing device for a mine water treatment station, which can well solve the above problems. Content of the Utility Model

A dosing barrel is installed on the upper surface of the base, and a motor is bolted to the top of the dosing barrel. A control cabinet is placed on the left side of the upper surface of the base. A metering pump is fixed on the right side of the upper surface of the base, and a conveying pipeline is arranged above the right side of the base.

[0007] It further includes: Both ends of the metering pump are respectively connected to the bottom of the dosing barrel and the left end of the conveying pipeline through connecting pipes. Spray heads are installed at equal intervals at the bottom of the connecting pipes. A stirrer is connected inside the dosing barrel.

[0008] The top of the stirrer penetrates through the interior of the chemical dosing tank, and the top of the stirrer is fixedly connected to the output end of the motor. Fixed feeding hoppers are provided on both the left and right sides of the top of the chemical dosing tank.

[0009] A movable plate is connected to the inner wall of the chemical dosing tank below the two feeding hoppers. A receiving groove is provided on the side of the inner wall of the chemical dosing tank where the movable plate is located. One side of the movable plate extends into the interior of the receiving groove, and a return spring is installed between one side of the movable plate and the inner wall of the receiving groove.

[0010] Preferably, the conveying pipeline spans across the defluorination reaction tank. The metering pump and the motor are electrically connected to the control cabinet. The chemical dosing tank, the spray head, the stirrer, the metering pump, and the conveying pipeline are all made of corrosion-resistant materials.

[0011] Preferably, the interior of the chemical dosing tank and the conveying pipeline are connected through the conveying pipeline. The spray head is threadedly connected to the conveying pipeline. The number of spray heads is arranged according to the size of the reaction tank.

[0012] Preferably, a sleeve is sleeved on the outer side of the upper end of the stirrer, and a ratchet assembly is installed between the sleeve and the stirrer. A semi-gear is sleeved and installed on the outer side of the sleeve. Driven gears are symmetrically arranged on the top of the chemical dosing tank with respect to the center point of the semi-gear, and the driven gears are connected to the movable plate through a traction rope.

[0013] Preferably, both of the movable plates are slidably connected to the chemical dosing tank and the receiving groove. The sleeve is rotatably connected to the chemical dosing tank. One end of the traction rope is fixed to one side of the movable plate, and the other end of the traction rope is wound around the shaft end of the driven gear.

[0014] Preferably, both of the driven gears are rotatably connected to the top of the chemical dosing tank through shafts, and both of the driven gears are meshed with the semi-gear. Scroll springs are installed at the connection positions between the shaft ends of both of the driven gears and the base.

[0015] Preferably, scraping plates are bolted to the outer side of the stirrer, and the outer sides of the scraping plates are in contact with the inner wall of the chemical dosing tank.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: The defluorination chemical dosing device for the mine water treatment station adopts a novel structural design, and the specific content is as follows:

[0017] (1) Use the chemical dosing tank to prepare defluorination agents with a certain concentration. Utilize the stirrer to fully stir to quickly dissolve the defluorination agent. Through the metering pump, the defluorination agent is transported to the spray head through the connecting pipe and the conveying pipeline. The spray head evenly sprays the agent into the reaction tank, improving the reaction speed of the defluorination agent, avoiding environmental and personal injuries, reducing the dosage of the agent, and enhancing the defluorination efficiency of the mine water.

[0018] (2) When the motor drives the agitator to rotate in the reverse direction, the agitator drives the sleeve to rotate by means of the ratchet assembly, causing the half gear to rotate and intermittently driving the driven gears on both sides to rotate. Subsequently, the driven gears wind up the traction rope, and at the same time, the traction rope pulls the movable plate to move into the accommodating groove. At this time, the defluorination agent and water in the two feed hoppers are sequentially added into the dosing barrel.

[0019] Further, when the half gear is not engaged with the driven gear, the driven gear rotates in the reverse direction under the energy storage of the scroll spring and relaxes the traction rope. At the same time, the movable plate is reset under the elastic force of the return spring and seals the feed hopper. By repeating the above operations, the two movable plates on the two feed hoppers intermittently stagger and move, thus realizing the quantitative addition of the defluorination agent and avoiding the influence on the dissolution rate and use effect of the defluorination agent due to excessive or insufficient addition.

[0020] (3) When the motor drives the agitator to rotate, the agitator drives the two scrapers to move along the inner wall of the dosing barrel, which can scrape off the residual agent, sediment or impurities on the inner wall of the dosing barrel, thus avoiding affecting the subsequent preparation and use of the defluorination agent.
