Description

Technical Field

[0001] This utility model relates to the field of Chlorella cultivation technology, specifically to a Chlorella cultivation wastewater treatment device. Background Technology

[0002] Chlorella, a single-celled microalga, has been widely used in wastewater treatment in recent years due to its rapid growth, high photosynthetic efficiency, and strong environmental adaptability. Traditional Chlorella cultivation systems mainly include two types: open raceway ponds and closed photobioreactors. Through photosynthesis, algae absorb nutrients such as nitrogen and phosphorus from wastewater, while simultaneously degrading organic pollutants and fixing CO2 to achieve carbon emission reduction. This technology is particularly suitable for treating organic wastewater from food processing and livestock farming, combining the dual advantages of pollutant removal and biomass resource recovery, which aligns with the concept of a green circular economy.

[0003] Existing Chlorella culture wastewater treatment devices do not have the function of automatically mixing wastewater and solvent, resulting in insufficient mixing of wastewater and solvent. Utility Model Content

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0014] A device for treating wastewater by cultivating Chlorella, based on Figures 1-3 As shown, it includes a base 1, a first processing mechanism 2 fixedly installed on the top of the base 1, a conveying mechanism 3 fixedly installed on the side of the first processing mechanism 2, a second processing mechanism 4 fixedly installed on the side of the conveying mechanism 3, an observation mechanism 5 fixedly installed on the surface of the second processing mechanism 4, and a control mechanism 6 fixedly installed on the top of the base 1. The first processing mechanism 2 includes a processing box 201 fixedly installed on the top of the base 1, a motor 202 fixedly installed on the top of the processing box 201, a rotating rod 203 fixedly installed on the output shaft of the motor 202, stirring blades 204 fixedly installed on both sides of the rotating rod 203, a wastewater inlet 205 fixedly installed on the top of the processing box 201, and a filter screen 206 fixedly installed on the bottom of the processing box 201. The delivery mechanism 3 includes a liquid pump 301 fixedly installed on the top of the base 1, a connecting pipe 302 fixedly installed on the left side of the liquid pump 301, and a connecting pipe 303 fixedly installed on the right side of the liquid pump 301. The second processing mechanism 4 includes a processing box 401 fixedly installed on the top of the base 1, a motor 402 fixedly installed on the top of the processing box 401, a rotating rod 403 fixedly installed on the output shaft of the motor 402, a stirring blade 404 fixedly installed on the side of the rotating rod 403, a solvent addition port 405 fixedly installed on the top of the processing box 401, mounting plates 406 fixedly installed on both sides of the inner wall of the processing box 401, a lamp tube 407 fixedly installed on the surface of the mounting plate 406, a drain pipe 408 fixedly installed on the side of the processing box 401, and a valve 409 provided on the top of the drain pipe 408.

[0015] according to Figure 1As shown, the observation mechanism 5 includes a sealed door 501 fixedly installed on the surface of the processing box 401, an observation window 502 opened on the surface of the sealed door 501, and a handle 503 fixedly installed on the side of the observation window 502.

[0016] It should be noted that the sealing door 501 maintains the airtightness of the treatment chamber 401, preventing external contamination and fluctuations in culture environment parameters. It allows operators to directly visually inspect the state of the algae solution inside the chamber without opening the sealing door 501. The handle 503 provides the opening and closing function of the sealing door 501, ensuring that it can be quickly opened for manual sampling or equipment maintenance when necessary, without interrupting the system operation.

[0017] according to Figure 1 As shown, the control mechanism 6 includes a console 601 fixedly installed on the top of the base 1, a control panel 602 opened on the surface of the console 601, and control buttons 603 fixedly installed below the control panel 602.

[0018] It should be noted that the processing parameters are displayed in real time through the touch interface of the control panel 602, and the operator's instructions are received.

[0019] according to Figures 2-3 As shown, the output shafts of motor 1 202 and motor 2 402 both pass through processing box 1 201 and processing box 2 401 and are fixedly connected to rotating rod 1 203 and rotating rod 2 403.

[0020] It should be noted that when the motor starts, the output shaft drives the rotating rod and the stirring blades fixed on it to make circular motion, forming a vortex in the tank, so that the wastewater and Chlorella can be fully mixed and contacted.

[0021] according to Figure 1 As shown, four support legs 7 are fixedly installed at the four corners of the bottom of the base 1.

[0022] It should be noted that the four support legs 7 adopt a symmetrical distribution design, and the weight of the device is evenly transferred to the ground through rigid connection to form a four-point support structure. When the motor is running, it absorbs high-frequency vibration energy and reduces the risk of resonance.

[0023] according to Figure 3 As shown, several sets of lamp tubes 407 are fixedly installed, and each set of lamp tubes 407 is set on the surface of the mounting plate 406 on both sides of the inner wall of the processing box 2 401.

[0024] It should be noted that each group of lamps 407 forms a symmetrical light source array on the inner wall of the second treatment chamber 401 through the mounting plate 406. When multiple groups of lamps 407 work together, they eliminate the shadow area in the chamber through cross-irradiation, ensuring that the light intensity is evenly distributed in all positions of the culture medium.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
