Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and specifically relates to a device for adding sewage treatment agents such as sodium acetate, sodium acetate, and carbon source. Background Art

[0002] The denitrification process in sewage treatment requires an organic carbon source. Because denitrifying bacteria need to use organic matter (carbon source) as an electron donor under anoxic conditions to reduce nitrates and nitrites to nitrogen gas, thereby removing nitrogen pollutants in the sewage. However, the carbon-nitrogen ratio in many sewage (such as domestic sewage, industrial wastewater) is low, that is, the carbon source is insufficient, resulting in low denitrification efficiency and the total nitrogen cannot meet the discharge standard. At this time, it is necessary to add carbon sources such as sodium acetate to supplement easily degradable organic matter to improve the denitrification effect.

[0003] However, when adding sodium acetate, sodium acetate, polyaluminum chloride, and carbon source agents into the dosing barrel for sewage treatment, since the distance between the stirring paddle and the bottom of the barrel is too far, and the bottom end of the barrel body is usually designed as a flat bottom, when mixing the agent with water, a stirring dead zone is easily formed at the bottom of the barrel body. After the solid agent settles, the agent agglomerates and is difficult to be stirred up, which is likely to cause uneven mixing of the agent and water; and when adding medicine and stirring at the same time, the water splashes brought up by the rotation of the paddle blades are easily splashed into the medicine storage barrel, which may cause the stored medicine to absorb moisture and become damp, making it inconvenient to store the medicine for a long time; when it is necessary to clean the inside of the medicine barrel, since the medicine barrel is installed in the fixing frame, it is inconvenient to manually lift the dosing barrel, and the gap between the barrel body and the frame is also small, making it difficult to take it out.

[0012] The beneficial effects of the present invention are:

[0013] (1) An adding device for sewage treatment agents such as sodium acetate, sodium acetate, and carbon source of the present invention threadedly installs the dosing mechanism inside the barrel cover. When starting the dosing mechanism, through the barrel cover, sodium acetate, sodium acetate, polyaluminum chloride, and carbon source agents can be added into the barrel body. Thus, while facilitating the addition of agents, the sealing performance inside the dosing mechanism can also be maintained. That is, the operator opens the cover plate installed on the medicine barrel, and sodium acetate, sodium acetate, polyaluminum chloride, and carbon source agents can be respectively placed into different medicine barrels for storage. Then, the cover plate is threadedly installed at the top of the medicine barrel to ensure the sealing performance inside the medicine barrel. Next, rotate the medicine barrel and threadedly install its end at the installation groove provided inside the barrel cover, so that the medicine barrel can be fixed inside the barrel cover. Since the barrel cover is threadedly installed at the top of the barrel body, when it is necessary to add agents into the barrel body, according to the control box, the control switch of the hydraulic rod can be activated. Since the telescopic end of the hydraulic rod is fixedly connected with a sealing block, when the telescopic end of the hydraulic rod drives the sealing block to slide towards the cover plate, the sealing block can be separated from the inner wall of the medicine barrel, and thus the inside of the medicine barrel is communicated with the inside of the barrel body through the barrel cover. The agents in the medicine barrel can be discharged into the barrel body through the gap between the sealing block and the medicine barrel. After the agent addition is completed, reset the hydraulic rod, and the sealing block can re-seal the bottom of the medicine barrel, thereby facilitating the maintenance of the sealing performance inside the medicine barrel and being conducive to preventing the agents from getting damp during storage.

[0014] (2) An adding device for sewage treatment agents such as sodium acetate, sodium acetate, and carbon source of the present invention starts the scraping mechanism, and the stirring mechanism rotates inside the barrel body to mix sodium acetate, sodium acetate, polyaluminum chloride, and carbon source agents with water. The setting of the scraping mechanism can not only scrape off the materials attached to the inner wall of the barrel body but also stir and mix the agglomerated agents at the bottom end of the barrel body. That is, after the agent addition is completed, the control switch of the motor is turned on, and the motor drives the rotating shaft to rotate inside the barrel cover. Since two first gears are fixedly installed on the rotating shaft, when the first gears rotate, they will drive the chain meshing on the side wall to rotate. Since the chain also meshes with the second gear fixed on the long rod, when the first gear drives the chain to rotate, the second gear will drive the long rod to rotate under the driving force of the chain. When several groups of brackets fixed on the long rod rotate inside the barrel body, the stirring paddles installed at the ends of the brackets can stir and mix sodium acetate, sodium acetate, polyaluminum chloride, and carbon source agents with water inside the barrel body. The rotating shaft rotates inside the barrel body, and the coupling installed at its end can rotate at the bottom of the barrel body. Several groups of rotating rods are equidistantly fixed on the coupling. When the rotating rods rotate with the coupling, the rotating rods can mix the agglomerated agents at the bottom end of the barrel body with water evenly, thereby being conducive to preventing the situation where the agents are not fully mixed with water, resulting in poor agent processing effects. The end of the coupling that is inclined is fixedly provided with a scraper. When the barrel body discharges liquid, the rotating scraper can scrape off the materials attached to the inner wall of the barrel body cleanly, thereby facilitating the subsequent cleaning of the inside of the barrel body.

[0015] (3) When the adding device for sodium acetate, sodium acetate, and carbon source used in the sewage treatment agent of the present invention needs to clean the inside of the barrel, push and rotate the limiting mechanism to make the supporting mechanism in an open state, and then rotate the positioning mechanism to make it slide and separate from the barrel, so that the barrel can be removed from the supporting mechanism, thereby facilitating the flushing and cleaning of its inside, that is: push the stopper provided in the mounting block by hand to make the stopper slide along the connecting rod into the mounting block. The stopper squeezes the telescopic spring sleeved on the connecting rod. When the telescopic spring is in a compressed state, the end of the stopper can be separated from the block installed on the fixing frame, so that the resisting rod loses the limit of the stopper and rotates the resisting rod towards the cross bar to separate it from the block. At this time, the barrel loses the block of the resisting rod, and the inside of the fixing frame can be in an open state; then, rotate the rotating block, and the rotating block drives the lead screw to rotate inside the fixing rod. The lead screw is threadedly connected with a sliding rod. Since the fixing rod limits the sliding rod, when the lead screw rotates, the sliding rod can slide along the inner wall of the fixing frame into the fixing rod, and the sliding rod drives the abutting plate fixed at the end to slide away from the barrel, so that the abutting plate can be separated from the barrel, and then it is convenient to take out the barrel from the inside of the fixing frame.

Detailed implementation manners

[0028] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0029] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 10 shown, a device for adding sewage treatment agents such as sodium acetate, sodium acetate, and carbon source of the present invention includes a control box 2; a support mechanism 1 is fixed on the control box 2; a barrel body 3 is installed on the support mechanism 1; a barrel cover 4 is threadedly connected to the barrel body 3; a medicine adding mechanism 7 is internally threaded and installed in the barrel cover 4; a scraping mechanism 8 is installed on the barrel cover 4; a stirring mechanism 9 is fixed on the scraping mechanism 8.

[0030] Specifically, as Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the scraping mechanism 8 includes a motor 801 and a rotating shaft 803. The top end of the bucket cover 4 is fixedly installed with a motor 801. The output end of the motor 801 is fixedly connected to a rotating shaft 803 through a coupling. A plurality of connecting shafts 804 are fixedly installed at equal intervals in a ring shape at the bottom end of the rotating shaft 803. A scraping plate 802 and two groups of rotating rods 805 are fixedly installed on the connecting shaft 804. When the rotating shaft 803 rotates in the barrel body 3, the connecting shaft 804 can rotate at the bottom of the barrel body 3. As the rotating rod 805 rotates with the connecting shaft 804, the rotating rod 805 can mix the caked medicament at the bottom end of the barrel body 3 with water evenly, which is beneficial to preventing the situation that the medicament processing effect is poor due to the insufficient mixing of the medicament and water. Moreover, both the scraping plate 802 and the rotating rod 805 are rotatably connected to the barrel body 3. One end of the connecting shaft 804 close to the scraping plate 802 is inclined, and both ends of the scraping plate 802 are provided with inclined plane structures. When the barrel body 3 discharges liquid, the attached materials on the inner wall of the barrel body 3 can be scraped clean by the rotating scraping plate 802, which is convenient for subsequent cleaning of the inside of the barrel body 3.

[0031] Specifically, as Figure 7 , Figure 8 and Figure 9 shown, the stirring mechanism 9 includes a first gear 901 and a chain 902. Two first gears 901 are fixedly installed on the rotating shaft 803. A chain 902 is engaged with the first gear 901. The first gear 901 is connected to a second gear 903 through the chain 902. A long rod 904 is fixedly installed on the second gear 903. Both the rotating shaft 803 and the long rod 904 are rotatably connected to the bucket cover 4. When the motor 801 is turned on to drive the rotating shaft 803 to rotate in the bucket cover 4, when the rotating shaft 803 drives the first gear 901 to rotate, the chain 902 will drive the second gear 903 to rotate, and then the long rod 904 will rotate along the inner wall of the bucket cover 4 under the driving force of the second gear 903. A plurality of groups of brackets 905 are fixedly connected to the long rod 904. Stirring paddles 906 are fixedly installed at the ends of the brackets 905. When the long rod 904 drives a plurality of groups of brackets 905 to rotate in the barrel body 3, the stirring paddles 906 on the brackets 905 can stir and mix the sodium acetate, sodium acetate, polyaluminum chloride and carbon source medicament and water in the barrel body 3.

[0032] Specifically, as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 10As shown, the chemical dosing mechanism 7 includes a cover plate 701 and a medicine barrel 702. Two medicine barrels 702 are threadedly installed on the barrel cover 4. The top end of the medicine barrel 702 is threadedly connected to the cover plate 701. By opening the cover plate 701, sodium acetate, sodium acetate, polyaluminum chloride, and carbon source agents can be separately placed into different medicine barrels 702 for storage. A hydraulic rod 704 is fixedly installed at the bottom end of the cover plate 701. The telescopic end of the hydraulic rod 704 is fixedly connected to a sealing block 705. The sealing block 705 is arranged in an isosceles trapezoid structure, and the sealing block 705 is snap-fitted with the medicine barrel 702. By starting the hydraulic rod 704, its telescopic end drives the sealing block 705 to slide in the direction close to the cover plate 701, and the sealing block 705 is separated from the inner wall of the medicine barrel 702, so that the inside of the medicine barrel 702 is communicated with the inside of the barrel body 3 through the barrel cover 4. The agent in the medicine barrel 702 can be discharged into the barrel body 3 through the gap between the sealing block 705 and the medicine barrel 702. An installation groove 703 is provided at the part of the barrel cover 4 close to the medicine barrel 702. By rotating the medicine barrel 702, its end can be threadedly installed at the part of the installation groove 703, so that the medicine barrel 702 is fixed inside the barrel cover 4.

[0033] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the support mechanism 1 includes a fixed frame 101 and a cross bar 102. The fixed frame 101 is fixedly connected to the control box 2. A number of cross bars 102 are fixedly installed at equal intervals at the bottom end of the fixed frame 101. A guide rod 103 is rotatably connected inside the cross bar 102. By means of the guide rod 103, the friction between the bottom end of the barrel body 3 and the cross bar 102 can be reduced, so as to facilitate the displacement of the barrel body 3. The barrel body 3 is located inside the fixed frame 101, and the guide rod 103 is in rolling connection with the bottom end of the barrel body 3. By pulling the barrel body 3, when its displacement drives the guide rod 103 to rotate, it is convenient to move the barrel body 3 out of the fixed frame 101.

[0034] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the fixing frame 101 is rotatably installed with a limiting mechanism 5, and the limiting mechanism 5 includes a stopper 501 and a mounting block 503. The fixing frame 101 is rotatably connected with the stopper 501, and the stopper 501 is located on the side of the fixing frame 101 away from the control box 2. The stopper 501 is fixedly connected with the mounting block 503, and a connecting rod 504 is fixedly connected inside the mounting block 503. A telescopic spring 505 is sleeved on the connecting rod 504, and the two ends of the telescopic spring 505 are respectively fixedly connected to the mounting block 503 and the stopper 506. The stopper 506 is arranged in an L-shaped structure. The stopper 506 is pushed by hand to slide along the side wall of the connecting rod 504 into the mounting block 503. The stopper 506 is pressed against the telescopic spring 505. The end of the stopper 506 can be separated from the card block 502 by squeezing. When the telescopic spring 505 is in a compressed state, the end of the stopper 506 can be separated from the card block 502. The connecting rod 504 passes through the inner wall of the stopper 506. The end of the fixing frame 101 close to the mounting block 503 is fixedly connected with the card block 502. The end of the card block 502 facing away from the fixing frame 101 is arranged in a regular hexagonal structure. The contact portion between the push rod 501 and the card block 502 is arranged in an arc surface structure. The stopper 506 is slidably connected with the card block 502. When the push rod 501 loses the limit of the stopper 506, the push rod 501 is rotated in the direction close to the cross bar 102 to separate it from the card block 502. At this time, the barrel body 3 loses the obstruction of the push rod 501, and the interior of the fixing frame 101 can be opened.

[0035] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, two positioning mechanisms 6 are symmetrically installed on the fixing frame 101, and the positioning mechanism 6 includes a fixing rod 601 and a screw rod 605. The fixing frame 101 is fixedly connected to the side away from the barrel body 3 with the fixing rod 601, and the screw rod 605 is rotatably connected inside the fixing rod 601. A rotating block 602 is fixedly installed at the end of the screw rod 605, and a sliding rod 604 is threadedly connected to the screw rod 605. The sliding rod 604 is slidably connected to the fixing frame 101 and the fixing rod 601, and the rotating block 602 is rotated to make It drives the screw rod 605 to rotate inside the fixed rod 601. When the screw rod 605 rotates, the sliding rod 604 can slide along the inner wall of the fixed frame 101 toward the inside of the fixed rod 601; the sliding rod 604 is fixedly connected with a support plate 603, and the support plate 603 contacts the side wall of the barrel body 3. The support plate 603 is arranged in an arc structure. The sliding rod 604 drives the support plate 603 installed at the end to slide in the direction away from the barrel body 3, so that the support plate 603 can be separated from the barrel body 3, thereby facilitating the removal of the barrel body 3 from the inside of the fixed frame 101.

[0036] When the present invention is in use, first, the operator opens the cover plate 701 installed on the medicine barrel 702, and can separately put sodium acetate, sodium acetate, polyaluminum chloride and carbon source agents into different medicine barrels 702 for storage. Then, the cover plate 701 is threadedly installed on the top end of the medicine barrel 702 to ensure the sealing performance inside the medicine barrel 702. Next, the medicine barrel 702 is rotated, and its end is threadedly installed at the installation groove 703 provided in the barrel cover 4, so that the medicine barrel 702 can be fixed inside the barrel cover 4. Since the barrel cover 4 is threadedly installed on the top end of the barrel body 3, when it is necessary to add agents into the barrel body 3, according to the control box 2, the control switch of the hydraulic rod 704 can be started. Since the telescopic end of the hydraulic rod 704 is fixedly connected with a sealing block 705, when the telescopic end of the hydraulic rod 704 drives the sealing block 705 to slide towards the cover plate 701, the sealing block 705 can be separated from the inner wall of the medicine barrel 702, and thus the inside of the medicine barrel 702 is communicated with the inside of the barrel body 3 through the barrel cover 4. The agents in the medicine barrel 702 can be discharged into the barrel body 3 through the gap between the sealing block 705 and the medicine barrel 702. After the agent addition is completed, the hydraulic rod 704 is reset, so that the sealing block 705 can re-seal the bottom of the medicine barrel 702, which is convenient for maintaining the sealing performance inside the medicine barrel 702 and is beneficial to preventing the agents from getting damp during storage.

[0037] After the agent addition is completed, the control switch of the motor 801 is turned on. The motor 801 drives the rotating shaft 803 to rotate inside the barrel cover 4. Since two first gears 901 are fixedly installed on the rotating shaft 803, when the first gears 901 rotate, they will drive the chain 902 engaged with the side wall to rotate. Since the chain 902 is also engaged with the second gear 903 fixed on the long rod 904, when the first gear 901 drives the chain 902 to rotate, the second gear 903 will drive the long rod 904 to rotate under the driving force of the chain 902. When several groups of brackets 905 fixed on the long rod 904 rotate in the barrel body 3, the stirring paddles 906 installed at the ends of the brackets 905 can stir and mix the sodium acetate, sodium acetate, polyaluminum chloride and carbon source agents and water inside the barrel body 3. The rotating shaft 803 rotates inside the barrel body 3, so that the coupling shaft 804 installed at its end rotates at the bottom of the barrel body 3. Several groups of rotating rods 805 are equidistantly fixed on the coupling shaft 804. When the rotating rods 805 rotate with the coupling shaft 804, the rotating rods 805 can mix the caked agents and water at the bottom end of the barrel body 3 evenly, which is beneficial to preventing the situation that the agents are not fully mixed with water and resulting in poor processing effect of the agents. The inclined end of the coupling shaft 804 is fixedly provided with a scraper 802. When the barrel body 3 discharges liquid, the attached materials on the inner wall of the barrel body 3 can be scraped clean by the rotating scraper 802, which is convenient for subsequent cleaning of the inside of the barrel body 3.

[0038] Push the stopper 506 provided inside the mounting block 503 by hand, so that the stopper 506 slides along the connecting rod 504 into the inside of the mounting block 503. The stopper 506 squeezes the telescopic spring 505 sleeved on the connecting rod 504. When the telescopic spring 505 is in a compressed state, the end of the stopper 506 can be separated from the fixture block 502 installed on the fixed frame 101. In this way, the abutting rod 501 loses the limit of the stopper 506, and the abutting rod 501 is rotated in the direction close to the cross bar 102 to separate it from the fixture block 502. At this time, the barrel 3 loses the block of the abutting rod 501, and the inside of the fixed frame 101 can be in an open state; Then, rotate the rotating block 602 again. The rotating block 602 drives the lead screw 605 to rotate inside the fixed rod 601. A sliding rod 604 is threadedly connected to the lead screw 605. Since the fixed rod 601 limits the sliding rod 604, when the lead screw 605 rotates, the sliding rod 604 can slide along the inner wall of the fixed frame 101 into the inside of the fixed rod 601. The sliding rod 604 drives the abutting plate 603 fixed at the end to slide in the direction away from the barrel 3, so that the abutting plate 603 can be separated from the barrel 3, thereby facilitating the removal of the barrel 3 from the inside of the fixed frame 101.
