[0002] Wastewater treatment refers to the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. According to the source, it can be divided into industrial wastewater treatment and domestic wastewater treatment. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people.

[0003] In wastewater treatment processes, chemical reagents are often added to effectively purify wastewater. However, the currently prevalent technique relies on manual, one-time addition of the required chemical reagents to the wastewater. This method has several drawbacks: the large-scale addition of chemical reagents in a short period may result in excessively high concentrations in some areas while the concentrations in other areas are insufficient, leading to uneven mixing. Consequently, some chemical reagents may not be able to fully exert their effects, resulting in low reaction efficiency and ultimately affecting the wastewater treatment outcome.

[0004] Therefore, a chemical dosing device for wastewater treatment is needed to solve the above problems. Utility Model Content

[0030] Example 1

[0031] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a chemical reagent dosing device for sewage treatment, which can realize the intermittent dosing of chemical reagents and solve the problem that the concentration of chemical reagents in some areas is too high while the concentration in other areas is insufficient and the mixing is uneven. It includes: sewage treatment tank 100 for treating sewage; it should be noted that the sewage treatment tank 100 adopts a container-type sewage treatment equipment, which is a commonly used and mature equipment in the art, and its specific structural composition will not be described here.

[0032] Multiple sets of storage tanks 200 are installed above the sewage treatment tank 100 for storing chemical reagents, and the multiple sets of storage tanks 200 store different types of chemical reagents respectively.

[0033] The dispensing unit 300 installed on the sewage treatment tank 100 is used to dispense chemical reagents. It includes a squeezing component and a dispensing component. The squeezing component is used to repeatedly squeeze the dispensing component to add chemical reagents into the sewage treatment tank 100.

[0034] It should be noted that the chemical reagents include disinfectants, deodorants, pH adjusters, etc., which are stored in different storage tanks 200. The dispensing component is connected to different storage tanks 200 to achieve the purpose of adding different chemical reagents.

[0035] In use, one set of storage tanks 200 is connected to the dispensing component. When chemical reagents need to be added, the dispensing component is repeatedly squeezed by the squeezing component to intermittently draw chemical reagents from the storage tank 200 and add them to the sewage treatment tank 100. This achieves intermittent dispensing of chemical reagents and solves the problem of local chemical reagent concentration being too high while other areas have insufficient concentration and uneven mixing.

[0036] Example 2

[0037] Reference Figures 1 to 5 This is the second embodiment of the present invention. Unlike the previous embodiment, the extrusion assembly includes a fixed box 301 fixedly connected to the sewage treatment tank 100. A reduction motor 302 is fixedly installed on one side of the fixed box 301. The output end of the reduction motor 302 passes through the fixed box 301 and is fixedly connected to a rotating rod 303. A special-shaped gear 304 is fixedly sleeved on the rotating rod 303. A sliding frame 305 is slidably arranged inside the fixed box 301. Two toothed plates 306 are fixedly installed on the inner wall of the sliding frame 305. The special-shaped gear 304 intermittently meshes with the two toothed plates 306 in sequence, driving the sliding frame 305 to move up and down reciprocally.

[0038] Specifically, the geared motor 302 and the rotating rod 303 drive the irregular gear 304 to rotate, and the irregular gear 304 and the two-position gear plate 306 drive the sliding frame 305 to move up and down reciprocally.

[0039] The dispensing component includes a dispensing cylinder 307 mounted on the wastewater treatment tank 100. A piston 308 is slidably connected to the inner wall of the dispensing cylinder 307. A push rod 309 is fixedly connected to the upper end of the piston 308. The upper end of the push rod 309 passes through the dispensing cylinder 307 and is fixedly connected to a moving block 310. The push rod 309 is slidably connected to the inner wall of the dispensing cylinder 307. A sliding frame 305 is fixedly connected to the moving block 310 via a connecting rod. A limiting hole for limiting the connecting rod is opened on one side of the fixed box 301. The connecting rod is slidably connected in the limiting hole.

[0040] Specifically, the sliding frame 305 and the connecting rod drive the moving block 310 to move up and down repeatedly, and the moving block 310 and the push rod 309 drive the piston 308 to move up and down repeatedly, intermittently drawing chemical reagents from the storage tank 200 and releasing them into the sewage treatment tank 100.

[0041] Among them, a one-way liquid outlet valve 3071 is fixedly installed at the lower end of the feeding cylinder 307. The lower end of the one-way liquid outlet valve 3071 is connected to the inside of the sewage treatment tank 100 through the liquid inlet pipe. A one-way liquid inlet valve 3072 is fixedly installed on one side of the feeding cylinder 307. A connecting hose 311 is fixedly installed at the other end of the one-way liquid inlet valve 3072.

[0042] Specifically, the one-way inlet valve 3072 and the one-way outlet valve 3071 facilitate the entry of chemical reagents from the tank 201 into the feeding cylinder 307 via the connecting hose 311, and then into the sewage treatment tank 100.

[0043] The multiple sets of liquid storage tanks 200 each include a tank body 201. Each tank body 201 is fixedly connected to a liquid filling pipe 2011 at its upper end, and the upper end of the liquid filling pipe 2011 is engaged with a top cover. Each tank body 201 has a fixedly connected external threaded pipe head 202 for communicating with a connecting hose 311 on one side. The side walls of the multiple tank bodies 201 are provided with transparent observation windows 203 for observing the liquid level of chemical reagents. The connecting hose 311 is threadedly connected to the external threaded pipe head 202 through an internal threaded sleeve, and one end of the external threaded pipe head 202 extends to the bottom of the chemical reagent.

[0044] Specifically, the connecting hose 311 is installed by connecting the internal threaded sleeve to the external threaded tube head 202, which facilitates quick replacement of different boxes 201 to dispense different chemical reagents.

[0045] The sewage treatment tank 100 is fixedly equipped with an inlet pipe 1001, a drain pipe 1002 is fixedly installed on one side of the sewage treatment tank 100, and a controller for controlling the entire device is fixedly installed on one side of the sewage treatment tank 100.

[0046] It should be noted that since the controller is a commonly used device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0047] In use, the hose 311 is connected to the inside of one of the housings 201. The geared motor 302 is started, and its output end drives the rotating rod 303 to rotate. The rotating rod 303 drives the special gear 304 to rotate. The special gear 304 intermittently meshes with the two toothed plates 306 in sequence, which drives the sliding frame 305 to move up and down reciprocally. The sliding frame 305 and the connecting rod drive the moving block 310 to move up and down reciprocally. The moving block 310 and the push rod 309 drive the piston 308 to move up and down reciprocally.

[0048] Furthermore, when the piston 308 moves upward, the pressure inside the feeding cylinder 307 decreases, and the chemical reagents inside the box 201 enter the feeding cylinder 307 through the connecting hose 311 under atmospheric pressure; when the piston 308 moves downward, the chemical reagents inside the feeding cylinder 307 are squeezed into the sewage treatment tank 100; repeating the above actions achieves intermittent chemical reagent dispensing.

[0049] In summary, a chemical reagent dosing device for wastewater treatment uses components such as a speed reducer motor 302, a special-shaped gear 304, and a toothed plate 306 in the extrusion assembly to drive a piston 308 to move up and down reciprocally, intermittently drawing chemical reagents from the storage tank 200 and discharging them into the wastewater treatment tank 100. This solves the problem of excessively high concentrations of chemical reagents in some areas while insufficient concentrations in other areas lead to uneven mixing, thereby improving the effectiveness of the chemical reagents and the reaction efficiency of wastewater treatment, and ultimately ensuring the effectiveness of wastewater treatment.

[0050] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
