Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a dosing device for treating wastewater from greenhouse turtle farming. Background Technology

[0002] Greenhouse turtle farming is a highly efficient aquaculture method. It utilizes the heat retention of greenhouses to extend the farming season, increase stocking density and yield, and thus boost farming income. Soft-shelled turtles are a high-protein, low-fat, and nutrient-rich aquatic product with significant economic value and market demand. By the end of 2022, Bengbu City in Anhui Province produced 14,800 tons of soft-shelled turtles, with Huaiyuan County alone accounting for 11,000 tons of this 14,800 tons, generated in greenhouses covering 300,000 square meters, with a value of 430 million yuan. Greenhouse turtle farming has brought considerable economic benefits to local farmers.

[0003] However, greenhouse turtle farming also presents several problems, the most prominent being water pollution. Due to the high air and water temperatures and small water volume within the greenhouse, prolonged intensive farming leads to the accumulation of organic matter, nutrients such as nitrogen and phosphorus, and pollutants like bacteria, resulting in declining water quality and a gradual deterioration of the ecological environment. Direct discharge without treatment can cause eutrophication, hypoxia, and algal blooms, impacting both water quality and the health of aquatic life. Monitoring data shows that ammonia nitrogen concentrations in the wastewater from greenhouse turtle farming are 1–2 mg / L, exceeding the standard by 5–10 times; COD is 50–150 mg / L, exceeding the standard by 4–8 times; pH is 5.5–6.5; and dissolved oxygen is 2–4 mg / L, all below standard values.

[0004] The conventional treatment for excessive ammonia nitrogen concentration in effluent is to add magnesium ammonium phosphate to adjust it. Currently, the dosing is done manually, which is labor-intensive for workers and not conducive to effluent treatment.

[0005] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a greenhouse turtle farming wastewater treatment and dosing device and its usage method, so as to make it more industrially valuable. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a device for treating and adding medicines to wastewater from greenhouse turtle farming.

[0007] This utility model discloses a treatment and dosing device for wastewater from greenhouse turtle farming. It includes a box body with three chambers formed by partitions: a dosing chamber, a dissolving chamber, and a storage chamber. A metering pump is installed on one side of the box body via an adapter frame and is connected to the storage chamber via a dosing pipe. A water inlet pipe is located on the rear side of the box body, with its end extending into the dosing chamber. The dosing chamber, dissolving chamber, and storage chamber are interconnected. An evacuation pipe is installed at the lower end of the box body, and the evacuation pipe is connected to the dosing chamber, dissolving chamber, and storage chamber via a connecting pipe. A medicine bin is installed and fixed at the top of the box body, and the medicine bin is connected to the dosing chamber.

[0008] This greenhouse turtle farming wastewater treatment and dosing device divides the tank into a dosing chamber, a dissolving chamber, and a storage chamber, which are used for injecting, mixing and dissolving, and storing the finished product, respectively. Finally, the medicine is discharged through a metering pump, completing the automatic mixing of the medicine solution. The medicine solution can also be injected into the breeding pond.

[0009] Furthermore, three sets of stirring motors are fixed at the upper end of the box. The output shaft of the stirring motor is fixedly connected to the stirring rod. Multiple sets of blades are installed on the stirring rod. The three stirring rods extend into the dosing chamber, the dissolving chamber and the storage chamber respectively.

[0010] The mixing efficiency of the reagents is improved by rotating the stirring rod driven by the stirring motor.

[0011] Furthermore, the upper end of the partition has a through groove to facilitate liquid flow.

[0012] The through groove at the upper end of the partition facilitates liquid flow, allowing the liquid to flow from the dosing chamber and dissolving chamber to the storage chamber.

[0013] Furthermore, there are through holes at the bottom of the partition, and a cover plate on the left side of the partition, the upper end of which does not contact the top of the box.

[0014] The cover plate serves to block the through hole at the bottom of the partition. After the liquid level is higher than the upper edge of the cover plate, it overflows into the cavity at the rear end.

[0015] Furthermore, an overflow pipe is installed on the side wall of the dosing chamber, with the lower end of the overflow pipe extending out of the side wall of the chamber and the upper end of the overflow pipe being higher than the upper edge of the cover plate.

[0016] The overflow pipe at the dosing chamber is positioned so that the liquid level inside the tank is too high, thus protecting the tank.

[0017] Furthermore, the bottom of the medicine bin has a through spiral discharge pipe, inside which is a spiral rod, which is fixedly connected to a reducer. The upper end of the reducer is connected to a dosing motor, and a vibrator is installed on the bottom outer wall of the medicine bin.

[0018] The dosing motor drives the screw rod inside the screw discharge pipe to rotate, discharging the agent evenly from the drug chamber at a certain rate, and the agent finally enters the dosing chamber.

[0019] Furthermore, the inlet pipe is sequentially equipped with a first valve, a filter solenoid valve, a diaphragm valve, a second valve, and a third valve. The second valve is installed on the transfer pipe and connected to the feed ring. The feed ring is located below the spiral discharge pipe. A heating ring is fitted on the transfer pipe. The fourth valve is connected to both sides of the solenoid valve on the inlet pipe through pipelines.

[0020] The valves on the inlet pipe are used to control the way water enters, guide water into the dosing chamber, and water can be flushed into the feed ring through the transfer pipe to flush and mix the agent first.

[0021] Furthermore, a fifth valve is installed on each connecting pipe, and a sixth valve is installed at the end of the drain pipe.

[0022] When the fifth valve on the connecting pipe is opened, it connects the dosing chamber, dissolution chamber, and storage chamber to the drain pipe, and is used to drain the liquid in each chamber after the machine is stopped.

[0023] Furthermore, the dosing chamber, dissolving chamber, storage chamber, and the top of the drug compartment all have openable covers.

[0024] The covers on the dosing chamber, dissolving chamber, storage chamber, and drug reservoir can be used for observation after being opened, making it easy to understand the amount of liquid and drug in each chamber and drug reservoir.

[0025] By means of the above solution, this utility model has at least the following advantages:

[0026] 1. Automated drug injection has been achieved;

[0027] 2. Divide the entire device into three boxes, which are used for adding, dissolving, and storing the drugs, respectively;

[0028] 3. The reagent in the storage chamber is metered out by a metering pump for downstream ammonia nitrogen treatment;

[0029] 4. The water inlet pipe is equipped with a solenoid valve and a manual valve. If the solenoid valve fails, the manual valve can be opened to continue operation.

[0030] 5. The efficiency of drug injection is determined by the operating efficiency of the dosing motor, which is used to prepare drug solutions of different concentrations.

[0031] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0041] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0042] See Figure 1This greenhouse turtle farming wastewater treatment and dosing device has a rectangular box 1 with two partitions 2 in the middle, which divide the box 1 into a dosing chamber 3, a dissolving chamber 4, and a storage chamber 5. One end of the water inlet pipe 9 is connected to a water source, and the other end extends into the dosing chamber 3. When water is injected into the dosing chamber 3, the medicine tank 11 also injects the medicine into the dosing chamber 3 simultaneously. According to the required solubility of the medicine, since the flow rate of the water inlet pipe 9 is fixed, the dosing rate of the medicine tank 11 needs to be adjusted by calculation to obtain the medicine solution with the target solubility. The dosing chamber 3, the dissolving chamber 4, and the storage chamber 5 are connected. After the medicine solution is initially mixed in the dosing chamber 3, it enters the dissolving chamber 4 for complete dissolution. Finally, the resulting medicine solution enters the storage chamber 5 for temporary storage.

[0043] All three chambers of the housing 1 are connected to the drain pipe 10 via connecting pipe 29. When it is necessary to discharge water and medicine from the housing 1, the connecting pipe 29 and the drain pipe 10 are used.

[0044] See Figure 2 Three sets of stirring motors 12 are installed on the horizontal plate at the top of the housing 1, corresponding to the dosing chamber 3, the dissolving chamber 4, and the storage chamber 5, respectively. Stirring rods 13 are installed on the output shaft of the stirring motors 12. The stirring rods 13 extend into the dosing chamber 3, the dissolving chamber 4, and the storage chamber 5. Multiple sets of blades are configured on each stirring rod 13. When the stirring motors 12 are working, the blades can dissolve the medicine more quickly, and the medicine in the storage chamber 5 at the rear end will not precipitate, ensuring that the concentration of the prepared medicine meets the requirements.

[0045] The upper end of the partition 2 has a through groove. When the liquid level in one cavity reaches the position of the through groove, it can overflow into the next cavity. The height of the through groove on the partition between the dissolving cavity 4 and the storage cavity 5 is relatively close to the bottom, so as to prevent the liquid in the dissolving cavity 4 from flowing back into the dosing cavity 3.

[0046] See Figure 3 and Figure 4 There is a through hole at the bottom of the partition 2. The cover plate 14 has a "C" shaped cross-section and its bottom is sealed to the box 1. The cover plate 14 can cover both sides of the through hole. There is a gap between the upper end of the cover plate 14 and the box 1. Figure 2 The liquid is poured in sequentially from left to right. When the liquid level in the cavity on the left side is higher than that in the cover plate 14, the liquid flows in from the top of the cover plate 14 and then flows into the cavity on the right side through the through hole at the bottom of the partition plate 2, thus transferring the liquid.

[0047] See Figure 2In order to avoid excessive liquid in the tank 1, an overflow pipe 15 is installed on the side wall of the dosing chamber 3 inside the tank 1. The upper end of the overflow pipe 15 is higher than the upper edge of the cover plate 14, and the overflowing liquid flows out from the opening located at the lower end of the tank 1.

[0048] See Figure 5 and Figure 6 The medicine bin 11 is installed at the top of the box 1. There is a spiral discharge pipe 32 running through the bottom of the medicine bin 11. When the dosing motor 17 is started, the dosing motor 17 drives the spiral rod located in the spiral discharge pipe 32 to rotate after being reduced by the reducer 16. This drives the medicine in the medicine bin 11 to move to the tail end of the spiral discharge pipe 32 and finally inject it into the dosing chamber 3. The vibrator 18 installed at the bottom of the medicine bin 11 is used to vibrate the powder medicine to avoid it from clumping and making it difficult to discharge.

[0049] See Figure 7 The first valve 19 on the inlet pipe 9 is used to connect to the water source, and its opening and closing controls whether water enters the pipe. The filter 20 located behind the first valve 19 is used to filter impurities in the water to ensure water safety. The solenoid valve 21 is used to control the water inlet. The first valve 19 is normally open, so the water inlet is controlled by the solenoid valve 21. The diaphragm valve 22 acts as an anti-backflow valve to prevent water from flowing back. The end of the inlet pipe 9 has a forked connector 25, which connects to the spiral discharge pipe 3. 2. The water collected at the feed ring 26 is simultaneously flushed at the transfer pipe 25 during the dosing operation of the spiral discharge pipe 32 to disperse the agent. The second valve 23 configured on the transfer pipe 25 is used to control whether water enters the transfer pipe 25. The heating ring 27 configured on the transfer pipe 25 is an electric heating device that can heat the water after being powered on, which is convenient for use in winter. The tail end of the water inlet pipe 10 enters the dosing chamber 3. A third valve 24 is configured at its tail end, which can be closed when necessary to prevent water from entering the dosing chamber 3.

[0050] See Figure 1 The dosing chamber 3, dissolving chamber 4, and storage chamber 5 are all connected to the drain pipe 10 via connecting pipe 29. Each connecting pipe 29 is equipped with a fifth valve 30. When it is necessary to drain liquid from one or more chambers, the corresponding fifth valve 30 and the sixth valve 31 at the end of the drain pipe 10 can be opened to perform the draining operation. The sixth valve 31 is set as a safety valve to prevent liquid from leaking out of the chamber when the fifth valve 30 fails.

[0051] The dosing chamber 3, dissolving chamber 4, storage chamber 5, and the cover above the drug compartment are openable structures, allowing observation of the drug solution and the drug's condition after opening.

[0052] The working principle of this utility model is as follows:

[0053] The method of using this greenhouse turtle farming wastewater treatment and dosing device is as follows: First, determine the concentration of the medicine solution to be prepared based on the required ammonia nitrogen content in the wastewater. Since the water injection efficiency of the inlet pipe 9 is constant, only the amount of medicine injected needs to be adjusted to meet the concentration requirements. The dosing motor 17's rotation speed is controlled, combined with the reducer 16 controlling the rotation efficiency of the spiral rod inside the spiral discharge pipe 32, thus controlling the medicine injection speed. The medicine is injected into the dosing chamber 3 at the position of the feed ring 26. At this time, there is a transfer pipe 25 at the end of the inlet pipe 9 that can extend into the feed ring 26. The medicine is flushed by water upon entry, increasing the dissolution rate. Meanwhile, the stirring rod 13 inside the dosing chamber 3 is stirred by the stirring motor 12. Driven by the rotation, the liquid is initially mixed in the dosing chamber 3. When the liquid level in the dosing chamber 3 reaches the upper edge of the cover plate 14, the liquid flows in through the channel between the cover plate 14 and the partition plate 2, and enters the dissolving chamber 4 through the through hole at the bottom of the partition plate 2. The structure of the storage chamber 5 at the rear end of the dissolving chamber 4 is the same, with a stirring motor 12 and a stirring rod 13. When the liquid is in the dissolving chamber 4, the stirring makes the drug and water mix better. When the liquid level in the dissolving chamber 4 reaches the upper edge of the cover plate 14 located in the dissolving chamber 4, it enters the storage chamber 5 through the through hole at the bottom of the partition plate 2. The stirring rod 13 in the storage chamber 5 continuously stirs to prevent the drug from settling and causing changes in the overall drug concentration.

[0054] Metering pump 7 is connected to storage chamber 5 through drug outlet pipeline 8. When the tailwater needs to be treated, the required drug solution mass is calculated and metering pump 7 can be started to deliver the prepared drug solution, which is convenient for tailwater treatment.

[0055] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0056] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0057] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
