Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a device for treating and dosing tail water of turtle breeding in a greenhouse and a use method thereof. Background Art

[0002] Greenhouse turtle farming is an efficient aquaculture method that can utilize the insulation effect of the greenhouse to extend the breeding season, increase breeding density and yield, and increase breeding income. Soft-shelled turtle is a high-protein, low-fat, nutritious aquatic product with high economic value and market demand. By the end of 2022, the output of soft-shelled turtles in Bengbu City, Anhui Province was 14,800 tons, of which the greenhouse breeding area in Huaiyuan County alone was 300,000 square meters, the output was 11,000 tons, and the output value reached 430 million yuan. Greenhouse turtle farming has brought considerable economic benefits to local farmers.

[0003] However, there are also some problems in greenhouse turtle farming, the most prominent of which is the pollution to the water environment. Due to the high air and water temperatures in the greenhouse, the small size of the aquaculture water body, and long-term intensive farming, organic matter, nutrients such as nitrogen and phosphorus, bacteria and other pollutants will accumulate in the water body, water quality conditions will decline, and the ecological environment will gradually deteriorate. If it is discharged directly without treatment, it will cause eutrophication, hypoxia, algae outbreaks and other problems in the water body, affecting the environmental water quality and the health of aquatic organisms. According to monitoring data, the concentration of ammonia nitrogen in the tail water of greenhouse turtle farming is 1-2 mg / L, 5-10 times higher than the standard; COD is 50-150 mg / L, 4-8 times higher than the standard; pH value is 5.5-6.5, and dissolved oxygen content is 2-4 mg / L, which are all lower than the standard value.

[0004] In the case of excessive ammonia nitrogen concentration in tail water, the conventional treatment method is to add magnesium ammonium phosphate for adjustment. The current method of adding drugs is manual operation, which causes a large workload for workers and is not conducive to tail water treatment.

[0008] This greenhouse turtle breeding tail water treatment and dosing device divides the box into a dosing chamber, a dissolving chamber and a storage chamber, which are respectively used for the injection of medicines, mixed dissolution and storage of finished products. Finally, the medicine is discharged through a metering pump to complete the automatic mixing of the medicine liquid, and the medicine liquid can also be injected into the breeding pond.

[0009] Furthermore, three stirring motors are fixed on the upper end of the box body, the output shafts of the stirring motors are fixedly connected to stirring rods, and multiple sets of paddles are installed on the stirring rods. The three stirring rods extend into the dosing chamber, the dissolving chamber and the storage chamber respectively.

[0010] The stirring motor drives the stirring rod to rotate, thereby improving the mixing efficiency of the medicine.

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

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

[0013] Furthermore, a through hole is provided at the bottom of the partition, and a cover plate is provided on the left side of the partition for covering, and the upper end of the cover plate does not contact the top end of the box body.

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

[0015] Furthermore, an overflow pipe is installed on the side wall of the medicine adding chamber, the lower end of the overflow pipe extends out of the side wall of the box body, and the upper end of the overflow pipe is higher than the upper edge of the cover plate.

[0016] The overflow pipe at the dosing chamber position is placed so that the liquid level in the entire box is too high, which serves the purpose of protecting the box.

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

[0018] The dosing motor drives the spiral rod in the spiral discharge pipe to rotate, and the medicine is discharged evenly from the medicine bin at a certain rate, and the medicine finally enters the dosing chamber.

[0019] Furthermore, the water inlet pipe is sequentially arranged with a first valve, a filter solenoid valve, a diaphragm valve, a second valve and a third valve. The second valve is installed at the connection between the transfer pipe and the feed ring. The feed ring is located below the spiral discharge pipe. A heating ring is provided on the transfer pipe.

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

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

[0022] After the fifth valve on the connecting pipe is opened, the dosing chamber, the dissolving chamber and the storage chamber are connected to the drain pipe, which is used to drain the liquid in each chamber after shutdown.

[0023] Furthermore, there are openable covers on the medicine adding chamber, the dissolving chamber, the storage chamber and the medicine bin.

[0024] The covers on the medicine adding chamber, dissolving chamber, storage chamber and medicine bin can be used for observation after opening, so as to understand the amount of liquid and medicine in each chamber and medicine bin.

[0025] A method for using a dosing device for treating tail water of turtle farming in a greenhouse, The first step is to connect the water inlet pipe to the water source and inject water into the dosing chamber, dissolution chamber and storage chamber; The second step is to start the dosing motor while filling the dosing chamber with water to inject the medicine from the medicine bin into the dosing chamber; Step 3: Start the stirring motor to preliminarily mix the medicine and water in the medicine adding chamber; Step 4: The liquid medicine in the medicine adding chamber is introduced into the dissolving chamber through the upper edge of the cover plate, and is fully mixed in the dissolving chamber; Step 5: The mixed liquid medicine enters the storage chamber for temporary storage; Step 6: Start the metering pump to deliver a quantitative amount of the liquid medicine.

[0026] After the water inlet pipe is connected to the water source, water is injected into the dosing chamber in sequence. At the same time, the dosing motor injects the medicine into the dosing chamber at a preset rate. Preliminary mixing is carried out in the dosing chamber. The liquid in the dosing chamber overflows into the dissolution chamber on the rear side, so that the medicine is completely dissolved in water to form a medicine. Finally, the medicine enters the storage chamber for temporary storage. When it is needed, the medicine is discharged quantitatively through the metering pump.

DETAILED DESCRIPTION

[0031] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] See also Figure 1 The medicine adding device for treating tail water of turtle breeding in greenhouse has a box body 1 of a rectangular parallelepiped structure, wherein there are two partitions 2 in the middle, which divide the box body 1 into a medicine adding chamber 3, a dissolving chamber 4 and a storage chamber 5, respectively. One end of a water inlet pipe 9 is connected to a water source, and the other end extends into the medicine adding chamber 3. When the medicine adding chamber 3 is injected with water, the medicine chamber 11 also injects the medicine into the medicine adding chamber 3 synchronously. According to the demand for the solubility of the medicine liquid, since the flow rate of the water inlet pipe 9 is fixed, the rate of medicine adding of the medicine chamber 11 needs to be adjusted through calculation to obtain the medicine liquid of the target solubility. The medicine adding chamber 3, the dissolving chamber 4 and the storage chamber 5 are connected. After the medicine liquid is preliminarily mixed in the medicine adding chamber 3, it enters the dissolving chamber 4, and is completely dissolved in the dissolving chamber 4. Finally, the medicine liquid enters the storage chamber 5 for temporary storage. The three chambers of the box body 1 are connected to the drain pipe 10 through the connecting pipe 29 , and the water and medicine in the box body 1 are discharged through the connecting pipe 29 and the drain pipe 10 when needed.

[0033] See also Figure 2 The three stirring motors 12 installed on the horizontal plate at the upper end of the box body 1 correspond to the dosing chamber 3, the dissolving chamber 4 and the storage chamber 5 respectively. A stirring rod 13 is installed on the output shaft of the stirring motor 12. The stirring rod 13 extends into the dosing chamber 3, the dissolving chamber 4 and the storage chamber 5, and a plurality of paddles are arranged on each stirring rod 13. When the stirring motor 12 is working, the paddles can dissolve the medicine faster, and the medicine liquid in the storage chamber 5 at the rear end will not precipitate, thereby ensuring that the concentration of the prepared medicine liquid meets the requirements.

[0034] There is a through groove at the upper end of the partition 2. When the liquid level in one cavity reaches the position of the through groove, it can overflow into the next cavity. In addition, the height of the through groove on the partition between the dissolution cavity 4 and the storage cavity 5 is relatively close to the bottom to prevent the liquid in the dissolution cavity 4 from flowing back into the dosing cavity 3.

[0035] See also Figure 3 and Figure 4 There is a through hole at the bottom of the partition 2. The cross section of the cover plate 14 is "C" shaped, and its bottom is tightly connected to the box body 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 body 1. Figure 2 The liquid is poured from left to right in sequence. When the liquid level in the cavity on the relatively left side is higher than the cover plate 14, the liquid flows in from the upper side of the cover plate 14 and then flows into the cavity on the relatively right side through the through hole at the bottom of the partition 2 to realize the transfer of the liquid.

[0036] See also Figure 2 In order to avoid excessive liquid in the box body 1, an overflow pipe 15 is installed on the side wall of the dosing chamber 3 in the box body 1. The upper end of the overflow pipe 15 is higher than the upper edge of the cover plate 14, and the overflow liquid flows out from the opening at the lower end of the box body 1.

[0037] See also Figure 5 and Figure 6 The medicine bin 11 is installed at the top of the box body 1, and a spiral discharge pipe 32 is inserted through the bottom of the medicine bin 11. When the dosing motor 17 is started, the dosing motor 17 is decelerated by the reducer 16 and drives the spiral rod in the spiral discharge pipe 32 to rotate, driving the medicine in the medicine bin 11 to move to the tail end of the spiral discharge pipe 32, and finally injected 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 clotting and difficulty in feeding.

[0038] See also Figure 7The first valve 19 on the water inlet pipe 9 is used to connect to the water source. Its opening and closing is used to control whether water is entering. The filter 20 located at the rear side of the first valve 19 is used to filter impurities contained in the water to ensure water safety. The solenoid valve 21 is used to control the switch of water inlet. The first valve 19 is usually normally open, so the control of water inlet is controlled by the solenoid valve 21. The diaphragm valve 22 plays a role of preventing backflow to avoid water backflow. The tail end of the water inlet pipe 9 has a bifurcated transfer pipe 25, and the transfer pipe 25 and the spiral discharge pipe 3 2 is collected at the position of the feed ring 26. When the spiral discharge pipe 32 is used for adding medicine, water is flushed synchronously at the position of the transfer pipe 25 to disperse the medicine. 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. After power is turned on, water can be heated for easy use in winter. The tail end of the water inlet pipe 10 enters the medicine adding chamber 3. A third valve 24 is configured at the tail end, which can be closed when necessary to prevent water from entering the medicine adding chamber 3.

[0039] See also Figure 1 The dosing chamber 3, the dissolving chamber 4 and the storage chamber 5 are connected to the drain pipe 10 through a connecting pipe 29, and a fifth valve 30 is installed on the connecting pipe 29. When it is necessary to discharge liquid from one or more of the chambers, the corresponding fifth valve 30 and the sixth valve 31 at the tail end of the drain pipe 10 can be opened to perform the liquid discharge operation. The sixth valve 31 is equivalent to insurance to prevent the loss of liquid in the cavity when the fifth valve 30 fails.

[0040] The cover plates above the medicine adding chamber 3, the dissolving chamber 4, the storage chamber 5 and the medicine bin are openable structures, and the conditions of the medicine liquid and the medicine can be observed after opening.

[0041] The working principle of the present invention is as follows: The method for using the greenhouse turtle breeding tail water treatment and dosing device is as follows: first, according to the need to treat the ammonia nitrogen content in the tail water, decide what concentration of liquid medicine to prepare, the water injection efficiency of the water inlet pipe 9 is constant, so only the amount of medicine injected needs to be adjusted to meet the demand for liquid medicine concentration preparation, by controlling the rotation speed of the dosing motor 17, combined with the reducer 16 to control the rotation efficiency of the spiral rod in the spiral discharge pipe 32, the speed of medicine injection is completed, the medicine is injected into the dosing chamber 3 through the position of the feed ring 26, at this time, there is a transfer tube 25 at the tail end of the water inlet pipe 9 that can penetrate into the feed ring 26, the medicine is flushed by water the moment it enters, thereby increasing the dissolution rate of the medicine, at this time the stirring rod 13 in the dosing chamber 3 is at the stirring motor 12 It rotates under the drive to perform preliminary fusion of the medicine in the medicine adding chamber 3. When the liquid level of the medicine in the medicine adding chamber 3 reaches the upper edge of the cover plate 14, the medicine flows in through the through groove between the cover plate 14 and the partition plate 2, and enters the dissolution chamber 4 through the through hole at the bottom of the partition plate 2. The storage chamber 5 at the rear end of the dissolution chamber 4 has the same structure, and both have a stirring motor 12 and a stirring rod 13. When the medicine is in the dissolution chamber 4, it is stirred to make the medicine and water blend better. When the liquid level of the medicine in the dissolution chamber 4 reaches the upper edge of the cover plate 14 located in the dissolution chamber 4, it also 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 continues to stir to avoid precipitation of the medicine, which leads to changes in the overall concentration of the medicine.

[0042] The metering pump 7 is connected to the storage chamber 5 through the medicine outlet pipeline 8. When the tail water at the rear end needs to be treated, the required quality of the medicine liquid is obtained by calculation, and the metering pump 7 can be started to transport the prepared medicine liquid to facilitate the tail water treatment at the rear end.
