Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a controlled dosing device for wastewater treatment. Background Technology
[0002] A large amount of wastewater is generated in daily life and production. Due to impurities mixed in the water or the influence of external conditions, the water deteriorates and loses its original function. Therefore, wastewater must be treated by special equipment to meet the standards before it can be discharged. In order to improve the wastewater treatment effect, chemical agents are added to the wastewater to improve the wastewater treatment efficiency, while also achieving precise control and efficient utilization of wastewater treatment agents.
[0003] A search revealed that publication number CN217103123U, application date 2022.05.05, discloses a dosing control device for wastewater treatment in a waterworks, comprising: a device body, which is fixedly mounted on a support base, a servo motor fixedly connected to the upper middle part of the device body, and a transmission rod installed at the output end of the servo motor, with an adjustment mechanism connected to the lower end of the transmission rod; a central gear, which is fixedly mounted on the transmission rod, with a lateral gear installed on the side of the central gear; and a conveying pipe, the upper end of which is installed below the transfer box, the lower end of which is installed on the side of a spray head, with a spiral spring providing a reset force installed on the back shaft end of the spray head, and the spray head being movably connected to the lower side of the device body.
[0004] However, it still has the following drawbacks in practical use:
[0005] 1. Existing wastewater treatment controlled dosing devices use bevel gear assemblies and reciprocating screws to quantitatively add chemicals to the two sides of the tank. This method is only suitable for chemicals that need to be added in equal amounts, and cannot achieve independent quantitative dosing of different chemicals according to different requirements, which affects the dosing efficiency and effectiveness.
[0006] 2. Existing controlled dosing devices for wastewater treatment adjust the spray range of the spray head through double-sided cams, push rods, and return springs, resulting in a complex structure that increases equipment cost and subsequent maintenance difficulty and cost. Therefore, we provide a controlled dosing device for wastewater treatment to solve the aforementioned problems. Utility Model Content

Detailed Implementation
[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0031] Example 1
[0032] Please see Figures 1 to 4 This utility model is a controlled dosing device for sewage treatment, including a medicine tank 100 and an I-shaped partition 101 fixed on its inner wall. The bottom of the medicine tank 100 is provided with a sliding groove 103 on both sides. An electromagnetic block 103a is embedded in the middle of one side wall of the sliding groove 103. An adjustment component 200 is provided at the bottom of the I-shaped partition 101. The adjustment component 200 includes a movable frame 201 slidably installed in the sliding grooves 103 at both ends, and iron blocks 202 embedded in the bottom of the side walls of the movable frame 201. Movable shafts 203 are rotatably installed in the top bearings at both ends of the movable frame 201.
[0033] Specifically, a drive assembly 102 is provided on the top of the medicine box 100. The drive assembly 102 includes a motor 102a installed at the center of the top of the medicine box 100, and a first rotating shaft 102b installed on the output shaft of the motor 102a via a coupling. The outer wall of the first rotating shaft 102b is fitted with a drive sprocket 102c, a drive cone sprocket 102d, and a gear disc 102e from top to bottom. The outer wall of the drive sprocket 102c is connected to the driven sprockets 102f at both ends via a chain. A stirring shaft 102g is installed at the bottom of the driven sprockets 102f. A driven cone sprocket is installed at one end of the moving shaft 203. Wheel 203a, driven cone wheel 203a meshes with rack on the outer wall of adjacent driving cone wheel 102d, spline shaft 204a is slidably installed in spline groove inside the other end of moving shaft 203; second rotating shaft 204 is fixedly provided at the other end of spline shaft 204a, the other end of second rotating shaft 204 passes through bearing on the outer wall of adjacent transfer box 206 and is connected to bearing on the inner wall of transfer box 206; impeller 205 is sleeved on the outer wall of second rotating shaft 204, connecting pipe 206a is provided at the top center of transfer box 206, and flexible hose 206b is provided at the bottom center of transfer box 206.
[0034] Furthermore, the I-shaped partition 101 divides the internal space of the medicine box 100 into four parts. The left and right symmetrical spaces are medicine storage spaces. The electromagnetic block 103a and the iron block 202 are attracted by magnetic force. The bottom of the movable frame 201 can slide in the slide groove 103. The sliding of the movable frame 201 will move the movable shaft 203. The driving sprocket 102c and the driven sprockets 102f at both ends are connected by chain drive to play a transmission role. The spline shaft 204a is slidably installed in the spline groove on the movable shaft 203 to play a connection transmission role. The rotation of the impeller 205 can transport the medicine liquid.
[0035] The operation process of this embodiment is as follows: medicine and water are introduced into the medicine storage chambers on both sides inside the medicine tank 100. Then, the motor 102a is started. The output shaft of the motor 102a rotates, driving the first rotating shaft 102b to rotate through the coupling. The rotation of the first rotating shaft 102b will drive the driving sprocket 102c, the driving cone wheel 102d, and the gear disc 102e on its outer wall to rotate synchronously. The outer wall of the driving sprocket 102c is connected to the driven sprockets 102f at both ends through a chain. Therefore, the rotation of the driving sprocket 102c will drive the driven sprockets 102f to rotate synchronously, thereby driving the stirring shaft 102g to rotate to mix the medicine and water. During the stirring process, the driving cone wheel 102d and the adjacent driven sprockets 102f rotate synchronously. The rack on the outer wall of the cone wheel 203a meshes, so the rotation of the driving cone wheel 102d will drive the driven cone wheel 203a to rotate synchronously. Under the action of the moving shaft 203, the spline shaft 204a and the spline groove, the second rotating shaft 204 will rotate synchronously. The rotation of the second rotating shaft 204 will drive the impeller 205 to rotate and deliver the liquid medicine, so as to achieve the purpose of quantitative delivery of liquid medicine. Under the magnetic attraction of the electromagnetic block 103a and the iron block 202, the position of the moving frame 201 can be adjusted, and the driving cone wheel 102d can be simultaneously or separately contacted with the driven cone wheels 203a at both ends. This achieves the purpose of equal addition of different liquid medicines or independent quantitative addition of different liquid medicines as needed, thereby improving the efficiency and effect of drug delivery.
[0036] Example 2
[0037] Please see Figure 2 and Figure 5 Based on Embodiment 1, unlike the first embodiment, a spraying assembly 300 is provided. The spraying assembly 300 includes a first nozzle 301 and a second nozzle 302 that are hinged and movably mounted at both ends of the bottom of the medicine tank 100. The opposite end faces of the first nozzle 301 and the second nozzle 302 are movably connected to the toothed plate 303 by hinges. This solves the problem that existing wastewater treatment control dosing devices adjust the spraying range of the spraying head by using double-sided cams, push rods, return springs, etc., which leads to a complex structure, increases equipment cost, and increases the difficulty and cost of subsequent maintenance.
[0038] Specifically, a connecting plate 303a is fixedly provided in the middle of the upper surface of the toothed plate 303, and the top of the connecting plate 303a is slidably installed at the bottom of the medicine box 100; the toothed plate 303 meshes with the rack on the outer wall of the adjacent toothed disc 102e, and the tops of the first nozzle 301 and the second nozzle 302 are connected to the hose 206b.
[0039] Furthermore, the tops of the first nozzle 301 and the second nozzle 302 can be adjusted at an angle by the hinge, and the connecting plate 303a plays a role in limiting and assisting the sliding of the toothed plate 303.
[0040] The operation process of this embodiment is as follows: During the delivery of the medicine liquid, the toothed disc 102e rotates with the first rotating shaft 102b, and the rack on the outer wall of the toothed disc 102e meshes with the rack on the adjacent toothed plates 303. Therefore, when the toothed disc 102e rotates, it will move the two toothed plates 303, causing the first nozzle 301 and the second nozzle 302 at both ends to tilt at a certain angle. Then, under the action of the connecting pipe 206a and the hose 206b, the medicine liquid is delivered and sprayed. The drive motor 102a reverses to make the first nozzle 301 and the second nozzle 302 rotate to the other side, thereby expanding the medicine spraying range. This structure is simple and low in cost.
