Description

Technical Field

[0001] This utility model belongs to the field of chemical wastewater treatment equipment, specifically a quantitative dosing device for chemical wastewater treatment. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial processes that has been polluted to a certain extent. This type of water has lost its original function and can no longer be used directly. It usually needs to be treated before it can be safely discharged or reused. Wastewater can be divided into four categories according to its source: industrial wastewater, domestic sewage, commercial sewage, and surface runoff. Each type of wastewater has its specific components and pollutant characteristics.

[0003] Chinese utility model patent CN222498733U discloses a wastewater treatment dosing device, including a conveying pipe. The inner wall of the conveying pipe is generally hourglass-shaped, gradually narrowing towards the center. Two sets of spiral guide vanes are symmetrically fixed to the inner wall of the conveying pipe. Six connecting holes are evenly distributed in a circular pattern near the center of the conveying pipe. A drain port is provided on the inner wall of the conveying pipe, communicating with the interior of the connecting holes. A conveying connection port is fixed to the outer wall of the conveying pipe, communicating with the interior of the connecting holes. Through the symmetrically arranged spiral guide vanes, the wastewater inside the conveying pipe can be made into a chaotic state. At the same time, the inside of the conveying pipe is in an hourglass state, and the flow velocity of the wastewater will increase in the middle of the conveying pipe. At this time, the agent is added into the conveying pipe through the drain port, and the agent will quickly mix with the wastewater. The agent can be added during the wastewater conveying process, thereby increasing the wastewater treatment efficiency.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the wastewater treatment dosing device is inconvenient to achieve quantitative dosing during use.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a quantitative dosing device for chemical wastewater treatment. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a quantitative dosing device for chemical wastewater treatment, thereby solving the problem that existing wastewater treatment dosing devices are inconvenient to achieve quantitative dosing during use.

[0007] A quantitative dosing device for treating chemical wastewater includes a tank, a feed pipe fixedly connected to one side wall of the tank, a discharge pipe fixedly connected to the lower end of the tank, a valve installed on the discharge pipe, a measuring cylinder fixedly connected to the upper end of the tank, a funnel fixedly connected to the lower end of the measuring cylinder, and a through groove opened at the upper end of the tank. The through groove is provided with a feeding component for quantitatively dispensing the measuring cylinder.

[0008] The feeding assembly includes a rotating column rotatably connected in the through groove, a rotating block fixedly fitted on the surface of the rotating column, a baffle fixedly connected to the lower surface of the rotating block, and two symmetrically arranged torsion springs fitted on the surface of the rotating column.

[0009] Preferably, the through groove has a "T" shaped structure, the upper surface of the baffle contacts the lower end of the funnel, one end of each of the two torsion springs is fixedly connected to both sides of the through groove, and the other end of each of the two torsion springs is fixedly connected to one side of the rotating block, which is two triangular blocks welded together.

[0010] Preferably, a limiting groove is formed on both sides of the through groove, and a limiting block is slidably connected in the limiting groove. One end of each of the two limiting blocks is fixedly connected to both sides of the rotating block.

[0011] Preferably, a servo motor is installed at the upper end of the tank, a rotating shaft is installed at the output end of the servo motor, and a push plate is welded to one side of the rotating shaft.

[0012] With the above technical solution, the application scenario of this device is to facilitate quantitative dosing of chemicals in wastewater. Specifically, the wastewater to be treated is fed into the inlet pipe, and the chemical powder to be purified is placed in the measuring cylinder. Starting the servo motor drives the rotating shaft, which in turn drives the push plate. When the push plate moves below the rotating block, it is pressed against the rotating block, thus pushing the push plate upwards. When the push plate passes the lower surface of the rotating block, the torsion spring is in a torsional state. After the push plate has completely passed the lower surface of the rotating block, the torsion spring returns to its initial state. Through this process, after the push plate passes under the rotating block, the baffle fixedly connected to the lower surface of the push plate moves downwards slightly. That is, after the push plate rotates one revolution, the baffle rotates downwards slightly, allowing the funnel below the measuring cylinder to dispense a quantitative amount of chemicals once. Compared with existing wastewater treatment dosing devices, this device can achieve quantitative dosing, effectively improving the control of the required amount of chemicals during wastewater treatment.

[0013] Preferably, the surface of the rotating shaft is welded with a plurality of symmetrically arranged stirring blades.

[0014] Preferably, the bottom of the tank is welded with a plurality of evenly distributed support legs, the lower end of the support legs is welded with a mounting block, and the mounting block is provided with a plurality of evenly distributed mounting holes.

[0015] With the above technical solution, when in use, the servo motor output drives the rotating shaft to rotate, which in turn drives the stirring blades on its surface to rotate, thereby allowing the medicine and sewage to mix more thoroughly. The mounting block can be installed on the ground through the mounting holes, thereby fixing the position of the device.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model introduces wastewater into a feed pipe and places the powdered medicine to be purified into a measuring cylinder. A servo motor drives a rotating shaft, which in turn rotates a push plate. When the push plate moves below the rotating block, it is pressed against the rotating block, causing it to rotate upwards. As the push plate passes the lower surface of the rotating block, a torsion spring is in a torsional state. After the push plate has completely passed the lower surface of the rotating block, the torsion spring returns to its initial state. This process allows the baffle fixedly connected to the lower surface of the push plate to move downwards slightly after the push plate rotates one revolution. This allows the funnel below the measuring cylinder to dispense a precise amount of medicine at once. Compared to existing wastewater treatment dosing devices, this device achieves precise dosing, effectively improving the control of the required amount of medicine during wastewater treatment.

[0018] 2. This utility model uses a servo motor output to drive the rotating shaft, which in turn drives the stirring blades on its surface to rotate, thereby allowing the medicine and sewage to mix more thoroughly. The mounting block can be installed on the ground through the mounting holes, thus fixing the position of this device. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 4 As shown: This utility model provides a quantitative dosing device for chemical wastewater treatment, including a tank 1, a feed pipe 101 fixedly connected to one side wall of the tank 1, a discharge pipe 102 fixedly connected to the lower end of the tank 1, a valve installed on the discharge pipe 102, a measuring cylinder 3 fixedly connected to the upper end of the tank 1, a funnel 301 fixedly connected to the lower end of the measuring cylinder 3, and a through groove 2 opened at the upper end of the tank 1. The through groove 2 is provided with a feeding component for quantitatively discharging the measuring cylinder 3.

[0027] The feeding assembly includes a rotating column 204 rotatably connected in the through groove 2, a rotating block 201 fixedly fitted on the surface of the rotating column 204, a baffle 202 fixedly connected to the lower surface of the rotating block 201, and two symmetrically arranged torsion springs 205 fitted on the surface of the rotating column 204.

[0028] The through groove 2 has a "T" shaped structure. The upper surface of the baffle 202 contacts the lower end of the funnel 301. One end of each of the two torsion springs 205 is fixedly connected to both sides of the through groove 2, and the other end of each torsion spring 205 is fixedly connected to one side of the rotating block 201. The rotating block 201 is made of two triangular blocks welded together.

[0029] Limiting grooves 209 are provided on both sides of the through groove 2. Limiting blocks 210 are slidably connected in the limiting grooves 209. One end of each limiting block 210 is fixedly connected to both sides of the rotating block 201.

[0030] A servo motor 206 is installed at the upper end of the tank body 1. A rotating shaft 207 is installed at the output end of the servo motor 206. A push plate 203 is welded to one side of the rotating shaft 207.

[0031] As can be seen from the above, the application scenario of this device is to facilitate the quantitative dosing of chemicals in wastewater. Specifically, the wastewater to be treated is introduced into the feed pipe 101, and the chemical powder to be purified is placed in the measuring cylinder 3. Starting the servo motor 206 drives the rotating shaft 207 to rotate, which in turn drives the push plate 203 to rotate. When the push plate 203 moves below the rotating block 201, it is pressed against the position of the rotating block 201, thus pushing the push plate 203 upwards. When the push plate 203 passes the lower surface of the rotating block 201, the torsion spring 205... When the push plate 203 is in a torsion state, after the push plate 203 has completely passed the lower surface of the rotating block 201, the torsion spring 205 returns to its initial state. Through the above process, after the push plate 203 passes under the rotating block 201, the baffle 202 fixedly connected to the lower surface of the push plate 203 is pushed down slightly. That is, after the push plate 203 rotates one revolution, the baffle 202 rotates down slightly. This allows the funnel 301 below the measuring cylinder 3 to dispense a quantitative amount of medicine once. Compared with existing sewage treatment dosing devices, this device can achieve the effect of quantitative dosing, effectively improving the control effect of the required amount of medicine during sewage treatment.

[0032] Example 2: Based on Example 1, a number of symmetrically arranged stirring blades 208 are welded to the surface of the rotating shaft 207.

[0033] The bottom of the tank body 1 is welded with several evenly distributed support legs 103, and the lower end of the support legs 103 is welded with an installation block 104, and the installation block 104 is provided with several evenly distributed installation holes.

[0034] As can be seen from the above, when in use, the rotating shaft 207 is driven to rotate by the output end of the servo motor 206, which in turn drives the stirring blades 208 on its surface to rotate, so that the medicine and sewage can be mixed more thoroughly. The mounting block 104 can be installed on the ground through the mounting hole, which can fix the position of the device.
