Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment chemical mixing device. Background Technology

[0002] Traditional chemical dosing and mixing devices often have many problems in wastewater treatment. For example, the chemical dosing method is relatively simple and imprecise, usually involving simple one-time or continuous high-flow dosing, making it difficult to achieve intermittent and precise chemical addition. This may lead to chemical waste or poor treatment results, because different stages of wastewater may require different dosages of chemicals to achieve the best treatment effect.

[0003] Furthermore, in the mixing process of chemicals and wastewater, most existing stirring devices adopt a continuous unidirectional rotation stirring method, which easily forms fixed water vortices, preventing some wastewater and chemicals from being fully mixed, thus reducing mixing efficiency and treatment effect. Moreover, for the discharge of treated wastewater, general discharge methods lack the function of further promoting mixing during the discharge process, which may result in uneven mixing of the discharged liquid and failure to meet discharge standards. Summary of the Invention

[0004] This invention provides a wastewater treatment chemical mixing device. By controlling the piston mechanism through a drive component, this invention enables intermittent chemical dosing and can precisely control the amount and time interval of chemical dosing according to the actual situation of the wastewater and the treatment stage.

[0005] A wastewater treatment chemical dosing and mixing device includes a reaction tank and a support frame fixed to the upper part of the reaction tank for supporting and connecting a chemical dosing assembly.

[0006] A drug dispensing assembly, mounted on the support, is used for drug dispensing;

[0007] A driving component, connected to the drug delivery component, is used to drive the drug delivery component to work;

[0008] The drug dispensing assembly includes a drug tank, a piston mechanism, and a drug dispensing pipe. The drug tank is fixed on the support. The lower side of the drug tank is fixedly connected to one end of the piston cylinder of the piston mechanism. The lower middle part of the piston cylinder of the piston mechanism is fixedly connected to the drug dispensing pipe. The lower part of the drug dispensing pipe is fixed to the support. The lower end of the drug dispensing pipe corresponds to the reaction tank. The piston rod of the piston mechanism is connected to the drive assembly.

[0009] As a further limitation of this technical solution, the driving assembly includes a slider, a horizontal shaft, a slide groove, and an electric push rod. The lower part of the slider is slidably disposed in the slide groove opened in the bracket. The upper end of the vertical shaft of the slider is fixedly connected to the piston rod of the piston mechanism. The telescopic rod of the electric push rod is fixedly connected to the slider. The outer shell of the electric push rod is fixedly connected to the bracket. The two ends of the horizontal shaft are respectively fixed to the bracket. The horizontal shaft is disposed in the slide groove and passes through the lower center of the slider.

[0010] As a further limitation of this technical solution, it also includes a stirring assembly for stirring and mixing the reagents and wastewater. The stirring assembly is connected to the support and includes a connecting rod, a limiting shaft, a rotating wheel, a rotating shaft, and a stirring wheel. The lower end of the rotating shaft is fixedly connected to the center of the stirring wheel. The stirring wheel is disposed at the bottom of the reaction tank. The upper end of the rotating shaft is rotatably connected to the support and the upper end of the rotating shaft is fixedly connected to the rotating wheel. The upper edge of the rotating wheel is fixedly connected to the limiting shaft. The limiting shaft is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the vertical shaft of the slider.

[0011] As a further limitation of this technical solution, a plurality of circumferentially arranged stirring blades are fixed on the upper side of the stirring wheel. The stirring blades are arc-shaped and arranged in a spiral.

[0012] As a further limitation of this technical solution, a drainage assembly is also included, disposed on the lower side of the reaction tank for drainage. The drainage assembly includes a drainage pipe, a transmission rod, a motor fixing block, and a drive motor. The drainage pipe is fixed to the lower side of the reaction tank. A symmetrical channel is provided at the lower part of the reaction tank. The reaction tank is connected to the drainage pipe through the channel. A transmission rod is disposed inside the drainage pipe. One end of the central axis of the transmission rod rotates to one end of the drainage pipe. One end of the central axis of the transmission rod is fixedly connected to the output shaft of the drive motor. The drive motor is fixedly connected to the reaction tank through the motor fixing block.

[0013] As a further limitation of this technical solution, the transmission rod is a spiral transmission rod, and a drain valve is provided at the other end of the drain pipe.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are:

[0015] By controlling the piston mechanism through the drive component, intermittent dosing of the agent is achieved. It can accurately control the amount and time interval of the agent according to the actual situation of the wastewater and the treatment stage, thereby improving the utilization rate of the agent.

[0016] The stirring assembly features a unique design. By linking with the drive assembly, the stirring wheel reciprocates within the reaction tank, preventing the formation of continuous vortices and allowing for more thorough mixing of the chemicals and wastewater. The stirring blades are arc-shaped and spirally arranged, which effectively agitates the water flow during rotation, accelerating the mixing speed, improving mixing efficiency, ensuring uniform distribution of the chemicals in the wastewater, promoting chemical reactions, and enhancing wastewater treatment quality.

[0023] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described in terms of the embodiments and implementation methods.

[0024] The specific embodiments of this utility model are as follows:

[0025] A wastewater treatment chemical dosing and mixing device includes a reaction tank 4 and a support 5, which is fixed on the upper part of the reaction tank 4 to support and connect the chemical dosing assembly 1.

[0026] The drug dispensing assembly 1 is mounted on the support 5 and is used for drug dispensing;

[0027] Drive component 2 is connected to the drug dispensing component 1 and is used to drive the drug dispensing component 1 to work;

[0028] The drug dispensing assembly 1 includes a drug tank 101, a piston mechanism 102, and a drug dispensing pipe 103. The drug tank 101 is fixed on the support 5. The lower side of the drug tank 101 is fixedly connected to one end of the piston cylinder of the piston mechanism 102. The lower middle part of the piston cylinder of the piston mechanism 102 is fixedly connected to the drug dispensing pipe 103. The lower part of the drug dispensing pipe 103 is fixed to the support 5. The lower end of the drug dispensing pipe 103 corresponds to the reaction tank 4. The piston rod of the piston mechanism 102 is connected to the drive assembly 2.

[0029] Furthermore, a one-way valve is provided at the connection between the drug tank 101 and the piston cylinder of the piston mechanism 102, which only allows the drug to enter the piston cylinder from the drug tank 101. A one-way valve is provided between the piston cylinder and the drug outlet pipe 103, which only allows the drug to enter the drug outlet pipe 103 from the piston cylinder.

[0030] The drive assembly 2 can drive the drug dispensing assembly 1 to work and realize the dispensing of the drug. The piston rod of the piston mechanism 102 of the drug dispensing assembly 1 is driven by the drive assembly 2 and moves back and forth in the piston cylinder. The piston rod can drive the piston block to move. The piston block retracts in the piston cylinder of the piston mechanism 102, drawing the drug from the drug tank 101 into the piston cylinder. The piston block is pushed in the piston cylinder of the piston, and the drug is pushed into the drug outlet pipe 103 and falls into the reaction tank 4 under the action of gravity.

[0031] In actual use, the drug is placed in the reaction tank 4, the drive component 2 is turned on, the drive component 2 can control the piston block of the piston mechanism 102 to move, realize the extraction and pushing of the drug, and discharge the drug from the drug outlet pipe 103 into the reaction tank 4 to realize the intermittent delivery of the drug.

[0032] In some embodiments, the drive assembly 2 includes a slider 201, a horizontal shaft 202, a groove 203, and an electric push rod 204. The lower part of the slider 201 is slidably disposed in the groove 203 opened in the bracket 5. The upper end of the vertical shaft of the slider 201 is fixedly connected to the piston rod of the piston mechanism 102. The telescopic rod of the electric push rod 204 is fixedly connected to the slider 201. The outer shell of the electric push rod 204 is fixedly connected to the bracket 5. The two ends of the horizontal shaft 202 are respectively fixed to the bracket 5. The horizontal shaft 202 is disposed in the groove 203 and passes through the lower center of the slider 201.

[0033] Specifically, the telescopic rod of the electric push rod 204 can drive the slider 201 to move within the slide groove 203, the horizontal shaft 202 guides the slider 201, and the slider 201 can drive the piston rod of the piston mechanism 102 to move, thereby realizing the extraction and pushing of the medicine.

[0034] Specifically, during the operation of the electric push rod 204, the time interval of the drug falling can be controlled by the extension and retraction time of the telescopic rod of the electric push rod 204, and the dosage of the drug drawn and pushed out each time can be controlled by the stroke setting of the telescopic rod of the electric push rod 204.

[0035] In some embodiments, a stirring assembly 3 is further included for stirring and mixing the medicine and wastewater. The stirring assembly 3 is connected to the support 5. The stirring assembly 3 includes a connecting rod 301, a limiting shaft 302, a rotating wheel 303, a rotating shaft 304, and a stirring wheel 305. The lower end of the rotating shaft 304 is fixedly connected to the center of the stirring wheel 305. The stirring wheel 305 is disposed at the bottom of the reaction tank 4. The upper end of the rotating shaft 304 is rotatably connected to the support 5. The upper end of the rotating shaft 304 is fixedly connected to the rotating wheel 303. The upper edge of the rotating wheel 303 is fixedly connected to the limiting shaft 302. The limiting shaft 302 is rotatably connected to one end of the connecting rod 301. The other end of the connecting rod 301 is rotatably connected to the vertical axis of the slider 201.

[0036] Specifically, a stirring wheel 305 is also installed in the reaction tank 4. The stirring wheel 305 can stir and mix the dripped medicine and sewage, thus accelerating the sewage treatment. The reciprocating movement of the slider 201 drives the connecting rod 301 to move. The connecting rod 301 drives the rotating wheel 303 to reciprocate through the limiting shaft 302. The rotating wheel 303 drives the rotating shaft 304 and the stirring wheel 305 to reciprocate, thus realizing the stirring and mixing function. Moreover, the reciprocating rotation of the rotating wheel 303 will not rotate continuously in one direction, thus avoiding the formation of a continuous vortex, resulting in a better mixing effect.

[0037] In some embodiments, a plurality of circumferentially arranged stirring blades 3051 are fixed on the upper side of the stirring wheel 305. The stirring blades 3051 are arc-shaped and arranged in a spiral.

[0038] Specifically, the stirring wheel 305 is equipped with stirring blades 3051. The arc-shaped stirring blades 3051 rotate with the stirring wheel 305 to disturb the water flow, allowing more water to flow faster and achieve a better mixing effect.

[0039] In some embodiments, a drainage assembly 6 is further included, disposed on the lower side of the reaction tank 4, for drainage. The drainage assembly 6 includes a drainage pipe 601, a transmission rod 602, a motor fixing block 603, and a drive motor 604. The drainage pipe 601 is fixed to the lower side of the reaction tank 4. A symmetrical channel 401 is provided at the lower part of the reaction tank 4. The reaction tank 4 is connected to the drainage pipe 601 through the channel 401. A transmission rod 602 is disposed inside the drainage pipe 601. One end of the central axis of the transmission rod 602 rotates to one end of the drainage pipe 601. One end of the central axis of the transmission rod 602 is fixedly connected to the output shaft of the drive motor 604. The drive motor 604 is fixedly connected to the reaction tank 4 through the motor fixing block 603.

[0040] The transmission rod 602 is a spiral transmission rod, and the other end of the drain pipe 601 is provided with a drain valve 7.

[0041] Specifically, by setting up the drainage component 6, continuous drainage is achieved. Drainage can occur during or after mixing. With the drainage valve 7 open, the transmission rod 602, which is spiral-shaped, is driven by a motor to rotate, thus discharging the liquid. The continuous rotation of the spiral transmission rod 602 enables secondary mixing of the medicine and wastewater during the drainage process, resulting in better mixing before discharge.

[0042] In use, wastewater is poured into reaction tank 4, and the reagent is placed into reagent tank 101. The reagent dispensing component 1 is controlled by drive component 2 to add the reagent into the wastewater in reaction tank 4. At the same time, drive component 2 also drives stirring component 3 to work, so as to achieve stirring and mixing. When drainage is required, drain valve 7 is opened and drain component 6 is started, and the reagent is discharged from drain pipe 601.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
