Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figures 1 to 4 In an embodiment of the utility model, a laboratory organic wastewater treatment device with an automatic flocculant cleaning function includes a premixing component 1 consisting of a mixing box 101, a first mixing bin 102, a second mixing bin 103, and a third mixing bin 104. The first mixing bin 102, the second mixing bin 103, and the third mixing bin 104 are sequentially formed inside the mixing box 101 along the horizontal direction. A fixed seat 2 is fixedly connected to one end of the mixing box 101 close to the first mixing bin 102. A driving motor 3 is installed on the top of the fixed seat 2. A reducer 4 is installed on the top of the partition plate between the first mixing bin 102 and the second mixing bin 103 and the partition plate between the second mixing bin 103 and the third mixing bin 104. A rotating base 5 is installed on the top of the end of the mixing box 101 away from the fixed seat 2.
[0027] A connecting shaft 7 is fixedly connected between the output end of the driving motor 3 and the input end of a reducer 4, between the output end of one reducer 4 and the input end of another reducer 4, and between the output end of another reducer 4 and the rotating base 5. The three connecting shafts 7 are respectively located in the inner cavities of the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104.
[0028] A stirring assembly 8 is provided on the outer side of the connecting shaft 7. The connecting shaft 7 rotates to drive the stirring assembly 8 to run in a circle, so as to stir and clean the mixed liquid in the inner cavity of the first mixing chamber 102, the second mixing chamber 103 and the third mixing chamber 104, and at the same time transport the mixed liquid along the distribution direction of the first mixing chamber 102, the second mixing chamber 103 and the third mixing chamber 104.
[0029] The stirring assembly 8 includes a connecting arm 801 , an arc-shaped side plate 802 , an arc-shaped shovel blade 803 , and a vertical baffle 804 .
[0030] There are multiple groups of connecting arms 801, which are distributed in a ring shape and fixed to the outside of the connecting shaft 7. Each group of connecting arms 801 includes two connecting arms 801 that are distributed in a spiral shape along the horizontal direction.
[0031] The arc-shaped side plate 802 is fixed in the middle of the two connecting arms 801, and the arc-shaped shovel blade 803 is fixed at the bottom of the arc-shaped side plate 802. The arc-shaped shovel blade 803 is in contact with the inner wall side of the first mixing bin 102, the second mixing bin 103, and the third mixing bin 104, and is used to perform scraping operations on the inner walls of the first mixing bin 102, the second mixing bin 103, and the third mixing bin 104.
[0032] The vertical baffle 804 is fixed to one end of the arc-shaped shovel blade 803, and the arc-shaped side plate 802, the arc-shaped shovel blade 803, and the vertical baffle 804 are combined as a whole into an arc-shaped bucket structure, which is used to push the mixed liquid inside the first mixing bin 102 to the second mixing bin 103 and the third mixing bin 104 in turn, and finally push it from the inside of the third mixing bin 104 to the next process.
[0033] The mixing box 101 is located at the top of one end of the second mixing bin 103 close to the first mixing bin 102, the top of one end of the third mixing bin 104 close to the first mixing bin 102, and the top of one end of the mixing box 101 close to the third mixing bin 104. A guide chute 105 is formed, and the guide chute 105 is used to guide the flow of the mixed liquid.
[0034] In this embodiment: when pre-treating laboratory organic wastewater, the organic wastewater and flocculant can be transported to the inside of the first mixing bin 102 in a certain ratio, and the drive motor 3 is started at the same time. The drive motor 3 drives the first connecting shaft 7 to rotate, and the first connecting shaft 7 drives the second connecting shaft 7 to rotate through the first reducer 4. The second connecting shaft 7 drives the third connecting shaft 7 to rotate through the second reducer 4, and the rotation speeds of the three connecting shafts 7 are reduced successively.
[0035] The three connecting shafts 7 can drive the stirring components 8 inside the first mixing bin 102, the second mixing bin 103, and the third mixing bin 104 to rotate, wherein the rotation of the stirring component 8 inside the first mixing bin 102 can preliminarily stir the mixed liquid inside the first mixing bin 102. At the same time, a group of stirring components 8 close to the second mixing bin 103, through the arc-shaped bucket structure composed of the arc-shaped side plate 802, the arc-shaped shovel blade 803, and the vertical baffle 804 and the end surface of the first mixing bin 102 form a space, which can drive the mixed liquid to move up to the top of the mixing box 101, so that the mixed liquid flows from the guide chute 105 to the inside of the second mixing bin 103, and is transported to the inside of the third mixing bin 104 after being stirred by the stirring component 8 inside the second mixing bin 103, and then is transported to the next process after being stirred for the third time inside the third mixing bin 104.
[0036] The flocculant and the organic wastewater can be fully mixed through multiple stirring and mixing, and the mixing and stirring frequencies inside the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104 are successively reduced, which is beneficial to the formation of flocculants (it should be noted that efficient stirring is required in the initial stage of flocculant addition so that the flocculant and the wastewater are fully mixed, and the stirring is reduced in the later stage so that small-particle flocculants are aggregated into large-particle flocculants). At the same time, in this process, the arc-shaped shovel blade 803 scrapes the side walls of the inner cavities of the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104, which can effectively prevent the flocculants from settling at the bottom of the mixing chamber, so that the device can maintain stable and continuous operation for a long time.
[0037] Please refer to Figures 1 to 3 A plurality of stirring components 8 are disposed inside the first mixing chamber 102 , the second mixing chamber 103 , and the third mixing chamber 104 , and the plurality of stirring components 8 are arranged in sequence along the trajectory of the connecting shaft 7 .
[0038] The connecting arms 801 distributed at the outermost ends of the multiple groups of stirring components 8 are respectively fitted with the inner walls of the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104, so as to realize the scraping operation of the end faces of the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104.
[0039] In this embodiment: by means of multiple groups of stirring components 8 arranged inside the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104, the mixed liquid can be fully mixed, and by means of multiple groups of stirring components 8 being distributed in sequence, the scraping area of the arc-shaped shovel blade 803 can completely cover the mixing chamber, thereby avoiding the occurrence of cleaning dead corners.
[0040] In addition, the connection arm 801 scrapes the end surfaces of the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104, thereby effectively avoiding the occurrence of flocculants remaining.
[0041] Please refer to Figures 1 to 3 The top of the mixing box 101 is located at both sides of the reducer 4 and the rotating base 5, and a protective plate 6 is fixedly connected. The guide chute 105 is distributed on one side of a protective plate 6, and the protective plate 6 is used to shield and protect the reducer 4 and the rotating base 5.
[0042] In this embodiment, when the mixed liquid passes through the diversion chute 105 , the protective plate 6 can effectively prevent the mixed liquid from contacting the reducer 4 and the rotating base 5 , thereby achieving the effect of protecting the reducer 4 and the rotating base 5 .
[0043] Please refer to Figures 1 to 4The rotation center of the connecting shaft 7 coincides with the center of the inner cavity trajectory of the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104. The heights of the arc-shaped side panels 802 and the vertical baffles 804 inside the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104 increase successively.
[0044] In this embodiment: through the structure in which the heights of the arc-shaped side panels 802 and the vertical baffles 804 inside the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104 increase successively, the single mixed liquid delivery volume between the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104 increases successively, while the mixed liquid delivery frequency between the first mixing chamber 102, the second mixing chamber 103, and the third mixing chamber 104 decreases successively, so that the two cooperate with each other to keep the delivery of the mixed liquid in a balanced state.
[0045] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
