Technical Field

[0001] This utility model relates to the technical field of microalgae purification devices, and in particular to a self-balancing liquid circulation microalgae purification device. Background Technology

[0002] In the field of wastewater treatment, using microalgae to purify wastewater is an environmentally friendly and efficient method. Its purification principle is to mix organic wastewater and microalgae to react, and the microalgae absorb nitrogen and oxygen organic matter in the organic wastewater through growth.

[0003] However, existing wastewater purification devices based on microalgae still have certain shortcomings in actual use: when heating wastewater to adapt to the growth environment of microalgae, the hot water around the heating unit is prone to local overheating and uneven heating, which affects the absorption efficiency of microalgae on nitrogen and phosphorus compounds in wastewater, and the purification effect needs to be further improved. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a self-balancing liquid circulation microalgae purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Purification tank and water pump;

[0010] A water delivery pipe is fixedly connected to the outlet end of the water pump, and the water delivery pipe is connected to the purification box.

[0011] A baffle tube is fixedly connected to the purification box, and the outlet end of the baffle tube faces the heating part.

[0012] Preferably, a drive cylinder is fixedly connected to the side wall of the purification box via an mounting plate, a sliding plug is slidably connected in the drive cylinder, and the end of the turbulence tube away from the purification box is connected to the drive cylinder.

[0013] Furthermore, a rotating rod is rotatably connected to the water supply pipe, a cam is fixedly connected to the rotating rod, a driving rod is slidably connected to the driving cylinder, the driving rod is fixedly connected to the sliding plug, and the end of the driving rod away from the sliding plug abuts against the cam.

[0014] Furthermore, an impeller disk is fixedly connected to the rotating rod.

[0015] Furthermore, a spring is fixedly connected to the slide, and the end of the spring away from the slide is fixedly connected to the inner wall of the drive cylinder.

[0019] Compared with the prior art, this utility model provides a self-balancing liquid circulation microalgae purification device, which has the following beneficial effects:

[0020] The parts of this device not described herein are the same as or can be implemented using existing technologies.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Example 1: Refer to Figures 1-5 A self-balancing liquid circulation microalgae purification device, comprising:

[0031] Purification tank 1 and water pump 2;

[0032] Multiple sets of breeding tanks 102 are fixedly connected in the purification box 1, and a heating element 3 is also fixedly connected to the side wall of the purification box 1.

[0033] The culture tank 102 is provided with exchange holes 1021, and multiple sets of exchange holes 1021 are evenly distributed on the culture tank 102;

[0034] A water supply pipe 5 is fixedly connected to the outlet end of the water pump 2, and the water supply pipe 5 is connected to the purification box 1.

[0035] A baffle pipe 401 is fixedly connected to the purification box 1, with the outlet end of the baffle pipe 401 facing the heating part 3.

[0036] It should be noted that the heating element 3 is a commercially available electric heating wire, and the power plug on the heating element 3 is connected to an external power source.

[0037] A drive cylinder 4 is fixedly connected to the side wall of the purification box 1 via an mounting plate 406. A sliding plug 403 is slidably connected in the drive cylinder 4. The end of the turbulence pipe 401 away from the purification box 1 is connected to the drive cylinder 4.

[0038] A rotating rod 6 is rotatably connected to the water supply pipe 5, and a cam 602 is fixedly connected to the rotating rod 6. A driving rod 405 is slidably connected to the driving cylinder 4. The driving rod 405 is fixedly connected to the sliding plug 403, and the end of the driving rod 405 away from the sliding plug 403 abuts against the cam 602.

[0039] An impeller disk 601 is fixedly connected to the rotating rod 6.

[0040] Reference Figure 4 It should be noted that the water-facing surface of the impeller disk 601 faces the bottom water delivery pipe 5 to ensure that when the water pump 2 delivers water through the water delivery pipe 5, the water flow can stably drive the impeller disk 601 to rotate.

[0041] A spring 404 is fixedly connected to the slide plug 403, and the end of the spring 404 away from the slide plug 403 is fixedly connected to the inner wall of the drive cylinder 4.

[0042] Reference Figure 4 The spring 404 installed inside the drive cylinder 4 enables the slide plug 403 to be quickly reset.

[0043] Reference Figure 4 , Figure 5 In specific implementation, a hemispherical drive block 4051 is fixedly connected to the end of the drive rod 405 away from the slide plug 403, and the arc end of the hemispherical drive block 4051 abuts against the cam 602.

[0044] Reference Figure 4 , Figure 5 By using the hemispherical drive block 4051 set on the drive rod 405, the cam 602 can stably squeeze and push the drive rod 405 to slide, reducing the situation of uneven squeezing when the cam 602 rotates.

[0045] Reference Figures 1-5 Before purification, staff placed microalgae in culture tube 102 and used water pump 2 to discharge the wastewater to be purified into purification tank 1.

[0046] Reference Figure 1 When wastewater is discharged, the heating unit 3 is activated simultaneously. The heating unit 3 heats the wastewater entering the purification box 1, thereby providing a suitable temperature for the growth and purification of microalgae.

[0047] Reference Figures 2-5When wastewater is input through the water supply pipe 5, the water flow impacts and drives the impeller 601 to rotate. At this time, the impeller 601 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the cam 602 to rotate. The cam 602 will then squeeze and push the drive rod 405 to slide, thereby pushing the slide plug 403 to squeeze out the gas in the drive cylinder 4. The gas squeezed out of the drive cylinder 4 will be blown into the purification box 1 through the baffle pipe 401. At this time, the baffle pipe 401 will blow and agitate the wastewater in the purification box 1. The wastewater will tumble in the purification box 1. Since the gas outlet of the baffle pipe 401 faces the heating part 3, it can mix the heated hot water around the heating part 3 with the unheated wastewater in the purification box 1, thereby making the wastewater in the purification box 1 heated evenly. This solves the problem of excessively high hot water temperature and uneven heating around the heating part 3 in the prior art. Moreover, the tumbling wastewater can fully contact the microalgae, so that the microalgae can fully absorb the nitrogen and phosphorus compounds in the wastewater, thereby quickly achieving the purification effect.

[0048] It should be noted that a drain pump is also connected to the side wall of the purification tank 1. After the wastewater is purified, the liquid in the tank is quickly discharged through the drain pump, so that the microalgae can be recycled.

[0049] An air supply pipe 402 is fixedly connected to the side wall of the drive cylinder 4, and a one-way valve is connected to the air supply pipe 402 and the turbulence pipe 401.

[0050] Reference Figure 4 By using one-way valves on the gas supply pipe 402 and the turbulence pipe 401, it is possible to prevent the backflow of the extracted gas when the sliding plug 403 is pushed, and also to prevent the liquid in the purification box 1 from flowing back into the drive cylinder 4 when the sliding plug 403 is extracting gas.

[0051] Reference Figure 1 , Figure 2 In practice, a limiting frame 101 is fixedly connected in the purification box 1, and the limiting frame 101 is located directly above the breeding tank 102.

[0052] By setting a limiting frame 101 in the purification box 1, the growth direction of microalgae can be restricted, thereby preventing microalgae from spreading and intertwining.

[0053] This utility model has been approved.

[0054] Example 2: Refer to Figure 6 , Figure 7 A self-balancing liquid circulation microalgae purification device is basically the same as in Example 1. Furthermore, a pressure accumulator 7 is fixedly connected to the side wall of the purification box 1, a conveying pipe 8 is fixedly connected to the air inlet end of the pressure accumulator 7, the conveying pipe 8 is connected to the air outlet end of the drive cylinder 4, and the exhaust end of the pressure accumulator 7 is connected to the turbulence pipe 401.

[0055] Reference Figure 7 It should be noted that a solenoid valve 701 is installed at the connection between the turbulence pipe 401 and the accumulator 7.

[0056] Reference Figures 6-7 In practice, the gas pushed back and forth by the sliding plug 403 in the drive cylinder 4 is stored in the accumulator cylinder 7. When it is necessary to impact and turbulent the purification box 1, the solenoid valve 701 can be opened. At this time, the gas in the accumulator cylinder 7 will be blown into the purification box 1 through the turbulence pipe 401, thereby disturbing the wastewater in the box, so that the microalgae can fully contact and purify the wastewater at different locations.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
