Technical Field

[0001] The utility model relates to the technical field of coal chemical wastewater purification, in particular to a coal chemical wastewater reagent dosing device. Background Art

[0002] Coal chemical wastewater refers to wastewater containing pollutants such as organic matter, inorganic salts, and heavy metals generated in the production process of coal mining and coal coking. Since it contains high levels of toxic and harmful substances, direct discharge will have a serious impact on the environment and human health. In order to reduce the pollution level of coal chemical wastewater, reagent addition is a common wastewater treatment method. Reagent addition is to add a certain amount of chemical reagents to the wastewater, and achieve the purpose of removing or transforming pollutants by adsorption, precipitation, oxidation-reduction and other effects on the pollutants in the wastewater;

[0003] It should be noted that when adding reagents, it is necessary to select appropriate reagents according to the specific composition of the wastewater and the characteristics of the pollutants, and control the dosage and method of the reagents to achieve the best treatment effect. In addition, the wastewater after the reagents are added still needs to undergo subsequent treatment processes, such as flocculation, sedimentation, filtration, biological treatment, etc., to achieve the final discharge standards. The existing reagent dosing devices usually have the following problems when in use:

[0004] At present, the existing reagent dosing device usually controls the amount of reagent added each time by manually controlling the valve when adding the reagent. Manual control cannot accurately control the dosage each time, resulting in unsatisfactory purification effect.

[0005] When dosing, the wastewater can only be dosed in a certain direction individually, and the dosing in other directions can only be carried out after the dosing of the agent in that area is completed. It is impossible to achieve simultaneous dosing on both sides, and the dosing efficiency is low. Utility Model Content

To achieve the above purpose, the utility model provides the following technical solutions: a coal chemical wastewater reagent dosing device, including a storage bin, a quantitative mechanism is plugged into the bottom of the storage bin, and a dosing mechanism is installed at the bottom of the quantitative mechanism.

[0007] The quantitative mechanism includes a disc, a quantitative tube is inserted at the bottom of the disc, a groove wheel passes through one end of the quantitative tube, a dial is attached to one side of the groove wheel, a lever is inserted at the top of the dial, the output shaft of the reduction motor is installed at the bottom of the dial, and a baffle is rotatably connected to the bottom of the quantitative tube.

[0013] Further preferably, the groove wheel and the fixed disk are connected in a rotational manner, and the baffle is attached to the inner wall of the fixed disk.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the utility model, the quantitative mechanism is used to realize that when adding chemicals to wastewater, the rotation of the groove wheel drives the quantitative tube to rotate, and the four quantitative tubes rotate together with the disc. The disc and the groove wheel have the same movement rhythm, and the intermittent movement is achieved by the lever. The time that each quantitative tube stays under the hole is the same, so that quantitative feeding of small amounts and multiple times is realized, the amount of chemical fed is accurately controlled, and the purification effect is better.

[0026] In this embodiment, Figure 4 As shown, the surface of the groove wheel 203 is provided with four radial grooves, and the dial 204 is rotated by the reduction motor 206; it should be noted that when the dial 204 rotates, it drives the upper lever 205 to rotate, and when the lever 205 is embedded in the radial groove, it drives the groove wheel 203 to rotate together, and the rotation of the groove wheel 203 drives the quantitative tube 202 to rotate, so as to achieve quantitative drug delivery in small amounts and multiple times, and the drug delivery amount is better controlled.

[0027] In this embodiment, Figure 4 As shown, there are four metering tubes 202, and the metering tubes 202 are distributed at equal angles with respect to the central axis of the disc 201; it should be noted that the four metering tubes 202 rotate together with the disc 201, the disc 201 and the groove wheel 203 move in the same rhythm, and intermittent movement is achieved through the lever 205, so as to discharge materials intermittently.

[0028] In this embodiment, Figure 3 As shown, two holes are respectively provided at the bottom of the storage bin 1, and the diameter of the holes is consistent with the diameter of the quantitative tube 202; it should be noted that when the quantitative tube 202 rotates to the bottom of the hole, the medicine in the storage bin 1 will enter the quantitative tube 202 through the hole, and the two holes are side by side, and the quantitative tubes 202 located on the same horizontal line are discharged at the same time. The time that each quantitative tube 202 stays under the hole is the same, and the amount of medicine received is fixed, thereby realizing quantitative dispensing.

[0029] In this embodiment, Figure 2 and Figure 3 As shown, the discharge port 302 and the guide disk 303 are set as a group, and there are two groups in total; it should be noted that the discharge port 302 and the hole at the bottom of the storage bin 1 are perpendicular to each other. When the metering tube 202 rotates to the discharge port 302, the material can be discharged from the discharge port 302, and the medicine is respectively added in two directions from the two guide disks 303. At this time, the other two metering tubes 202 start to receive the material for the next round of delivery.

[0030] In this embodiment, Figure 1 and Figure 2 As shown, the groove wheel 203 and the fixed disk 301 are connected in a rotating manner, and the baffle 207 is attached to the inner wall of the fixed disk 301; it should be noted that when the groove wheel 203 is moved by the lever 205, it rotates along the surface of the fixed disk 301 to control the position of the groove wheel 203, and the baffle 207 is attached to the top of the fixed disk 301 without affecting the sliding of the quantitative tube 202 along the fixed disk 301.

The reduction motor 206 is started, and the animated dial 204 rotates slowly. When the lever 205 is embedded in the radial groove of the groove wheel 203, the groove wheel 203 is driven to rotate slowly, and the quantitative tube 202 is further driven to rotate slowly. When the quantitative tube 202 is rotating, other areas of the disc 201 cover the hole. Each time the lever 205 is turned one circle, the four quantitative tubes can be driven. 202 rotates 90°, and the two parallel metering tubes 202 filled with medicine rotate 90° to the discharge port 302. At this time, under the impact of the internal medicine and the action of gravity, the baffle 207 rotates 90° along the metering tube 202, opens the opening at the bottom of the metering tube 202, and the medicine is discharged from the two guide plates 303 to both sides at the same time. While discharging, the other two perpendicular metering tubes 202 are aligned with the holes in the storage bin 1 to start receiving the materials, until the lever 205 rotates back a circle, and drives the groove wheel 203 and the metering tube 202 to rotate again, and the next round of medicine addition is carried out.
