Description

Technical Field

[0001] The utility model belongs to the technical field of electroplating wastewater treatment equipment, and in particular relates to a chemical reagent delivery device. Background Art

[0002] Electroplating wastewater contains heavy metal pollutants. In order to avoid heavy metal pollutants from polluting the environment, the heavy metal pollutants in the electroplating wastewater need to be treated before the wastewater is discharged to meet the requirements for wastewater discharge.

[0003] The existing treatment method is to put the electroplating wastewater containing heavy metal pollutants into a chemical regulating tank, and then sprinkle chemical reagents into the chemical regulating tank to make the chemical reagents undergo redox reactions with the heavy metal ions in the electroplating wastewater. The sprinkled chemical reagents first react with the electroplating wastewater on the top layer of the chemical regulating tank, and then slowly sink to react with the electroplating wastewater under the top layer of the chemical regulating tank, thereby reducing the reaction rate and causing poor uniformity in the placement of chemical reagents, which affects the reaction effect.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0024] like Figure 1-Figure 6 As shown, this embodiment provides a chemical reagent delivery device, including: a delivery component 10 and a stirring component 20 arranged on the periphery of the delivery component 10, the delivery component 10 is used to deliver chemical reagents into the chemical pool, and the stirring component 20 is used to accelerate the diffusion of the delivered chemical reagents to improve the uniformity of the chemical reagent delivery and at the same time increase the reaction rate of the chemical reagents and electroplating wastewater.

[0025] Specifically, Figure 1-3 , Figure 5 As shown, the delivery assembly 10 includes a guide column 11, a rotating rod 12, and a delivery box 13. The guide column 11 is arranged vertically, and a guide groove 111 is arranged in a circumferential array along the outer circumference of the guide column 11. The guide groove 111 is arranged along the axial direction of the guide shaft 11, and the guide groove 111 passes through the inner wall of the guide column 11. The rotating rod 12 is arranged in the guide column 11 and is concentric with the guide column 11. A plurality of spiral grooves 121 are arranged in a circumferential array on the outer wall of the rotating rod 12, and the number of the spiral grooves 121 is consistent with the number of the guide grooves 111. A delivery box 13 is correspondingly arranged in each guide groove 111, and a support rod 131 is arranged on a side of the delivery box 13 facing the rotating rod 12. The side of the support rod 131 facing the rotating rod 12 is in rolling cooperation with the corresponding spiral groove 121, and the two side walls of the support rod 12 are in sliding cooperation with the guide groove 111.

[0026] Specifically, the stirring assembly 20 includes a turntable 21 and a plurality of stirring rods 22 arranged to rotate on the bottom surface of the turntable 21. The turntable 21 is arranged at the upper end of the rotating rod 12, and the stirring rods 22 are located at the periphery of the distribution track of the delivery box 13 to avoid interference with the delivery box 13 when the turntable 20 drives the stirring rods 22 to rotate synchronously.

[0027] Specific operation process:

[0028] The device is placed in a chemical pool, and the rotating rod 12 is started to rotate clockwise, so that the rotating rod 12 drives the turntable 22 to rotate synchronously, so that the turntable 22 drives multiple stirring rods 22 to rotate synchronously, and at the same time, the spiral groove 121 drives the support rod 131 to move upward along the guide groove 111. When the delivery box 13 moves to the top of the guide groove 111, the rotating rod 12 rotates counterclockwise, so that the spiral groove 121 drives the support rod 131 to move downward, so that the delivery box 13 moves downward, and so on and so forth, so that the chemical reagents in the delivery box 13 are continuously sprayed outward, and the diffusion of the chemical reagents is accelerated under the action of the stirring rod 22, so as to improve the uniformity of the chemical agent delivery, and at the same time improve the reaction rate of the chemical reagents and the electroplating wastewater. The rotation of the rotating rod 22 can be driven by a motor, so that the motor rotates forward and reversely, and the rotating rod 12 rotates back and forth.

[0029] Specifically, Figure 1 , Figure 2 , Figure 6As shown, a gear 112 is fixedly provided at the upper end of the guide column 11, and a planetary gear 221 is provided at the upper end of the stirring rod 22, so that the planetary gear 221 is meshed with the gear 112, and the planetary gear 221 is rotatably connected to the turntable 21. When the turntable 21 rotates, the planetary gears 221 corresponding to each stirring rod 22 can be driven to rotate synchronously along the axis of the turntable 21, and at the same time, the planetary gears 221 can be rotated around the axis of the stirring rod 22, so that the chemical reagent sprayed from the delivery box 13 is stirred, thereby further increasing the uniformity of the chemical reagent delivery and improving the reaction rate.

[0030] At the same time, in order to make the stirring effect better, Figure 1 , Figure 6 As shown, stirring blades 222 are arranged in an array along the axial direction of the outer periphery of the stirring rod 22, and the stirring blades 222 are in a spiral sheet structure, so that the chemical reagent sprayed from the delivery box 13 can be better stirred and flipped upward, thereby further diffusing the chemical reagent.

[0031] Specifically, Figure 4 As shown, in order to prevent the delivery box 13 from rotating during the upward or downward movement, the cross-section of the support rod 131 is set to a rectangular structure, and a ball 132 is provided at one end of the support rod 131 facing the rotating rod 12, so that the ball 132 and the spiral groove 121 are rolled together to reduce the friction between the support rod 131 and the spiral groove 121, while increasing its service life.

[0032] A discharge hole 133 is vertically provided on a side of the delivery box 13 away from the guide groove 111, so that the chemical reagent is sprayed out through the discharge hole 133, and a feed pipe 134 is provided at the bottom of the delivery box 13 to avoid interference between the stirring rod 22 and the feed pipe 134 when the stirring rod 22 rotates. At the same time, chemical reagents are continuously injected into the delivery box 13, so that there is pressure in the delivery box 13, so that the chemical reagents are sprayed out along the discharge hole 133.

[0033] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
