Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, and in particular to a wastewater treatment dosing device. Background Art

[0002] Wastewater refers to water containing pollutants generated after use, production or other activities. It includes industrial wastewater, agricultural wastewater and domestic sewage. Wastewater may contain harmful substances such as organic matter, heavy metals, chemicals, bacteria, etc., which pose a potential threat to the environment and human health. Therefore, wastewater needs to be treated to remove or reduce pollutants in it in order to protect water resources and maintain ecological balance. In the prior art, when treating wastewater, it is necessary to add corresponding drugs to neutralize it to meet the emission standards. The existing dosing of solid drugs (activated carbon particles) usually adopts two methods: manual dosing and equipment dosing. Manual dosing usually adds the drug to the wastewater at one time (adding in time periods will increase labor intensity), and it is difficult to adjust the amount of drug added according to the amount of wastewater. Too little drug will affect the treatment effect of the wastewater, and too much drug will cause too much waste. Equipment dosing can add quantitatively in real time, but it usually needs to be equipped with electronic devices such as liquid level gauges, metering pumps and electrical control boxes. Although it can control the amount of drug addition, it also increases energy loss accordingly. At the same time, the mixing effect of wastewater and drugs is poor. After the drug is added, it is easy to settle at the bottom, and it is difficult to achieve a good neutralization effect, resulting in poor wastewater treatment effect. Therefore, we have made improvements to this and proposed a wastewater treatment dosing device. Summary of the invention

[0017] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0018] like Figure 1-Figure 10 As shown, a wastewater treatment dosing device proposed in one embodiment of the present invention comprises a mixing barrel 1, the mixing barrel 1 is used to hold wastewater for treatment, a dosing box 3 for placing activated carbon particles is arranged on the mixing barrel 1 through a bracket 2, the dosing box 3 is used to place activated carbon particles, and the activated carbon particles are used to adsorb and purify the wastewater, which belongs to the prior art distinguishing features of the present invention. The distinguishing technical features of the present invention also include: The control mechanism 4 includes a discharge shell 401 connected to the bottom of the dosing box 3, and the inner wall opposite sides of the discharge shell 401 are rotatably penetrated by a guide column 402. Preferably, the inner wall opposite sides of the discharge shell 401 are provided with an arc groove, and the guide column 402 is rotatably inserted in the arc groove. The outer surface of the guide column 402 is in contact with the inner wall of the arc groove. A plurality of embedding grooves 403 are provided on the outer surface of the guide column 402. When the embedding groove 403 faces upward, the activated carbon particles in the dosing box 3 can fall into the embedding groove 403. When the embedding groove 403 faces downward, the activated carbon particles in the embedding groove 403 can be discharged through the discharge shell 401. Intermittent discharge can only be performed when the guide column 402 rotates. When the guide column 402 stops rotating, the guide column 402 The discharge shell 401 can be used as a plugging member to plug the discharge shell 401. The guide column 402 is provided with an adjusting member 404 for adjusting the capacity of the embedding groove 403. By setting the adjusting member 404, it is used to adjust the capacity of the embedding groove 403, change the capacity of the activated carbon particles placed in the embedding groove 403, and thus adjust the dosage. The bottom of the discharge shell 401 is connected with a water pipe 405. Preferably, the water pipe 405 is inclined, and its end with a low inclination faces the mixing barrel 1. When wastewater is added, the wastewater is injected from the end with a high inclination of the water pipe 405, thereby transporting the wastewater to the mixing barrel 1. The water pipe 405 is connected with a casing 406, and an impeller shaft 407 is rotatably penetrated in the casing 406. Preferably, the impeller shaft 407 includes a casing that rotates and penetrates The shaft of the shell 406 is fixed with a plurality of annularly distributed blades. The impeller shaft 407 is connected to the guide column 402 through a linkage 408. When wastewater is injected from the end of the water pipe 405 with a high inclination, the water flow will first flow through the shell 406, and the water flow will impact the blades of the impeller shaft 407, thereby driving the impeller shaft 407 to rotate, and allowing the water flow to flow through the shell 406 to the mixing barrel 1. When the impeller shaft 407 rotates, the guide column 402 is driven to rotate through the linkage 408, so that the activated carbon particles in the dosing box 3 are transported to the water pipe 405 through the discharge shell 401. The activated carbon particles will be preliminarily mixed with the wastewater in the water pipe 405, and then circulated to the mixing barrel 1. The wastewater and the activated carbon particles are not Instead of adding the activated carbon particles to the mixing barrel 1 in sequence, the activated carbon particles are added in real time when the wastewater is added. The two can be preliminarily mixed in the water delivery pipe 405 first, and then transported to the mixing barrel 1 together after the preliminarily mixing. The activated carbon particles are added in real time when the wastewater is added, and when the wastewater is stopped, the drug addition is stopped at the same time. During the drug addition process, there is no need for the intervention of electronic devices such as liquid level meters, metering pumps and electric control boxes, which reduces energy loss, thereby achieving the effect of automatic drug addition, making the operation simple and convenient to add drugs. The capacity of the embedded material tank 403 can be adjusted by the adjusting member 404 according to the amount of wastewater added, so as to adjust the amount of drugs added in real time, which can avoid the situation of insufficient drug addition and the situation of excessive drug addition causing waste; The stirring mechanism 5 is arranged on the support 2, and is used to stir and mix the wastewater and the activated carbon particles. After the wastewater and the activated carbon particles are preliminarily mixed in the water delivery pipe 405 and transported to the mixing barrel 1, the stirring mechanism 5 stirs them to achieve secondary mixing, thereby improving the mixing effect of the wastewater and the activated carbon particles and improving the treatment effect of the wastewater; In this solution, wastewater and drugs are not added in sequence in the conventional manner. Instead, drugs are added in real time while wastewater is added. When wastewater addition stops, drug addition also stops at the same time. No electronic equipment is required, thereby achieving the effect of automated drug addition, making operation simple and drug addition convenient. The capacity of the embedded groove 403 can be adjusted by the adjustment member 404 according to the amount of wastewater added, thereby adjusting the amount of drugs added in real time, which can avoid insufficient drug addition and excessive drug addition causing waste. During the adding process, preliminary mixing is first performed, and then secondary mixing is performed by stirring through the stirring mechanism 5, thereby improving the mixing effect.

[0019] like Figure 6 and Figure 7 As shown, the specific structure of the adjusting member 404 of the present invention is disclosed to achieve the function of adjusting the capacity of the embedding groove 403. The adjusting member 404 includes a screw rod 4041 rotatably set on the guide column 402, and an adjusting plate 4042 is threadedly sleeved on the screw rod 4041. A plurality of adjusting blocks 4043 are fixedly arranged on the adjusting plate 4042. The plurality of adjusting blocks 4043 are respectively slidably inserted in the plurality of embedding grooves 403. When it is necessary to adjust the capacity of the embedding groove 403, the screw rod 4041 is twisted to rotate and move. Under the action of the thread, the adjusting plate 4042 is driven to move, so that the plurality of adjusting blocks 4043 slide along the plurality of embedding grooves 403 respectively. When the adjusting blocks 4043 slide, part of the capacity space of the embedding groove 403 is occupied, thereby playing the role of adjusting the capacity of the embedding groove 403. Preferably, as Figure 7 As shown, the adjusting block 4043 is constructed with an arc surface, and the arc surface thereon is adapted to the arc surface of the guide column 402 . Therefore, under the premise that the capacity of the embedding groove 403 can be effectively adjusted, the normal rotation of the guide column 402 is not affected.

[0020] like Figure 4As shown, the specific structure of the linkage member 408 of the present invention is disclosed. The linkage member 408 includes a driven groove wheel 4081 fixedly mounted on the guide column 402. A transmission dial 4082 that is transmission-matched with the driven groove wheel 4081 is fixedly mounted on the shaft of the impeller shaft 407. Preferably, the driven groove wheel 4081 includes a disk body, and a plurality of arc grooves and a plurality of dial grooves are opened on the outer side of the disk body. The number of the arc grooves and the dial grooves are both four and staggered. Preferably, the number of the embedded material grooves 403 is four, and the four embedded material grooves 403 correspond to the four arc grooves or the four dial grooves one by one, respectively. The transmission dial 4082 includes a notched disk, and a support plate is arranged at the notch of the notched disk, and a dial rod that is slidingly matched with the dial groove is arranged on the support plate. When the impeller shaft 407 rotates under the impact of the water flow, it drives the transmission dial 4082 to rotate synchronously. When the transmission dial 4082 rotates, the lever thereon slides with the groove on the driven groove wheel 4081. After the transmission dial 4082 rotates one circle, the driven groove wheel 4081 rotates 90 degrees, so that the impeller shaft 407 can drive the guide column 402 to rotate. At the same time, the guide column 402 realizes the effect of intermittent rotation. When the guide column 402 rotates 90 degrees, it will pause. During the pause time, not only does it facilitate the activated carbon particles in the dosing box 3 to have enough time to fill the embedding groove 403, but it also facilitates the activated carbon particles in the embedding groove 403 to have enough time to fall out, thereby playing a role in adjusting the dosage.

[0021] like Figure 3 , Figure 5 and Figure 6 As shown, a further technical solution for adding medicine to the medicine adding box 3 of the present invention is disclosed. A guide rod 6 is rotatably penetrated on the opposite side of the inner wall of the medicine adding box 3. A plurality of levers 7 are arranged in an array on the outer surface of the guide rod 6. A pulley assembly 8 is connected between the guide rod 6 and the shaft of the impeller shaft 407. When the guide column 402 blocks the discharge shell 401 and activated carbon particles are stored in the medicine adding box 3, the activated carbon particles in the medicine adding box 3 are squeezed against each other. The activated carbon particles located in the lower layer, that is, close to the guide column 402, will be squeezed by the activated carbon particles in the upper layer, causing the activated carbon particles to condense into blocks, making it impossible to It can fall smoothly into the embedding groove 403 and cannot effectively fill the embedding groove 403. A guide rod 6 is rotatably set in the dosing box 3, and a plurality of levers 7 are arranged in an array on the guide rod 6. When the impeller shaft 407 rotates under the impact of the water flow, it drives the guide rod 6 to rotate synchronously through the pulley assembly 8, so that the lever 7 stirs the activated carbon particles in the dosing box 3, so that the activated carbon particles will not be squeezed into blocks, and the activated carbon particles can fall smoothly into the embedding groove 403, so as to ensure that the activated carbon particles can be added in real time, thereby improving practicality.

[0022] like Figure 2 and Figure 8As shown, the specific structure of the stirring mechanism 5 of the present invention is disclosed to achieve stirring and mixing of wastewater and activated carbon particles. The stirring mechanism 5 includes a vertical rod 501 rotatably arranged on the bracket 2, the top end of the vertical rod 501 is connected to a motor 504 arranged on the bracket 2, and the bottom end of the vertical rod 501 is connected to a chassis 502, and a plurality of stirring rods 503 distributed in a ring are arranged on the chassis 502. The stirring rods 503 include columns arranged on the chassis 502, and a plurality of mounting disks are arranged in an array along the height direction of the columns, and a plurality of inclined plates are arranged in an array on the outer peripheral side of the mounting disks. The motor 504 performs work, and its output shaft drives the vertical rod 501 to rotate, thereby driving the chassis 502 and the plurality of stirring rods 503 to rotate, and the plurality of stirring rods 503 rotate with the vertical rod 501 as the center of the circle, thereby stirring the wastewater to improve the mixing effect of the wastewater and the activated carbon particles.

[0023] like Figure 8 and Fig.10 As shown, a further technical solution for the stirring mechanism 5 of the present invention is disclosed. When the wastewater is stirred, the activated carbon particles can also be circulated and transported up and down. The bottom of the bracket 2 is provided with a sleeve 9 coaxial with the vertical rod 501 through a support rod. A conical groove is provided on the inner bottom wall of the mixing barrel 1. The bottom plate 502 is constructed in a conical shape and is plugged into the conical groove. There is a material passing gap between the bottom end of the sleeve 9 and the bottom plate 502. A spiral plate 10 is fixed on the vertical rod 501. The outer edge of the spiral plate 10 is in contact with the inner wall of the sleeve 9 and overlaps. When activated carbon particles are added to the wastewater, some of the activated carbon particles will sink to the bottom and accumulate on the bottom plate 502. Preferably, as Fig.10 As shown, the bottom plate 502 is constructed in a conical shape, and there is a material passing gap between the bottom end of the sleeve 9 and the bottom plate 502. Therefore, part of the activated carbon particles on the bottom plate 502 will slide down to the bottom of the sleeve 9 through the material passing gap. When the thickness of the activated carbon particles accumulated on the bottom plate 502 is higher than the lowest end of the sleeve 9, as the vertical rod 501 rotates, the spiral plate 10 is driven to rotate. The vertical rod 501, the spiral plate 10 and the sleeve 9 cooperate to form a spiral conveyor, thereby transporting the activated carbon particles accumulated on the bottom plate 502 and part of the wastewater upward, and then transporting them from the top of the sleeve 9. The wastewater and activated carbon particles are discharged out (the top of the sleeve 9 is connected to the bracket 2 through a support rod, and the top of the sleeve 9 has an exposed space, through which the wastewater and activated carbon particles can be discharged), and then the wastewater and activated carbon particles fall downward, so that the stirring mechanism 5 can not only stir the wastewater horizontally, but also circulate the wastewater and activated carbon particles up and down, which can not only prevent the activated carbon particles from accumulating and sinking to the bottom, but also prevent the activated carbon particles and wastewater from being distributed in layers up and down, and at the same time, the activated carbon particles and wastewater are no longer affected by the stirring effect and present a single horizontal vortex, thereby further improving the mixing effect of the wastewater and activated carbon particles.

[0024] like Figure 8 and Fig. 9As shown, a further technical solution for the stirring mechanism 5 of the present invention is disclosed. A gear ring 11 is fixedly provided on the sleeve 9 through a support rod. The stirring rod 503 is rotatably connected to the chassis 502. A gear 12 meshing with the gear ring 11 is fixedly provided on the stirring rod 503. When the chassis 502 drives a plurality of stirring rods 503 to rotate, the gear 12 and the gear ring 11 mesh. Since the position of the gear ring 11 is fixed, the rotation of the gear 12 drives the stirring rod 503 to rotate, so that the stirring rod 503 not only rotates with the vertical rod 501 as the center of the circle, but also can rotate on its own. Preferably, the mounting plates on two adjacent stirring rods 503 are staggered up and down, and the inclined structure of the upper inclined plate can realize rotary cutting of wastewater. When the contact area with the wastewater is increased, the stirring resistance can also be reduced. The rotary cutting stirring can not only apply horizontal stirring force to the wastewater, but also drive the wastewater to surge up and down, thereby further improving the stirring and mixing effect of the wastewater.

[0025] like Figure 2 As shown, a further technical solution of the present invention for the sleeve 9 is disclosed. A conical shell 13 is provided on the sleeve 9, and the conical shell 13 covers the gear ring 11 and the gear 12. Since the wastewater and activated carbon particles will flow upward along the sleeve 9 and be discharged through the top of the sleeve 9, by providing the conical shell 13 on the sleeve 9, the wastewater and activated carbon particles discharged from the top of the sleeve 9 can be guided to the position corresponding to the stirring rod 503 and then slide down, so that when the two slide down, the rotating stirring rod 503 can beat and stir the two. At the same time, the conical shell 13 covers the gear ring 11 and the gear 12 to prevent the activated carbon particles falling downward from being stuck between the gear ring 11 and the gear 12, ensuring that the gear ring 11 and the gear 12 can be smoothly meshed. It should be noted that the wastewater liquid level of the mixing barrel 1 is lower than the height of the gear ring 11, so that when the stirring rod 503 stirs the wastewater, the activated carbon particles mixed in the wastewater will not contact the gear ring 11 or the gear 12.

[0026] like Figure 2As shown, a further technical solution for the conical shell 13 of the present invention is disclosed. The conical shell 13 is rotatably sleeved on the sleeve 9. A plurality of stirring rods 503 are rotatably penetrated through the conical shell 13. A plurality of ring-shaped strips 14 are configured on the top of the conical shell 13. By rotatably sleeved on the sleeve 9, the conical shell 13 can be rotated on the sleeve 9. The stirring rods 503 are rotatably penetrated through the conical shell 13, so that the conical shell 13 does not interfere with the normal rotation of the stirring rods 503. At the same time, when the stirring rods 503 are rotated with the vertical rods 50 1 is rotated as the center of a circle, the stirring rod 503 can drive the conical shell 13 to rotate. By constructing a plurality of strips 14 in an array on the top of the conical shell 13, when the conical shell 13 rotates, the strips 14 thereon can play a guiding role, so that the wastewater and activated carbon particles discharged from the top of the sleeve 9 can be effectively diffused in a ring shape. Preferably, the end of the water delivery pipe 405 with a low inclination is located above the conical shell 13, so that the wastewater and activated carbon particles output from the water delivery pipe 405 can also be diffused in a ring shape into the mixing barrel 1, thereby improving the mixing effect.

[0027] like Fig.10 As shown, a further technical solution for the sleeve 9 of the present invention is disclosed. A plurality of seepage holes 15 are arranged in an array through the sleeve 9. Since activated carbon particles are added while wastewater is added, and wastewater is gradually added into the mixing barrel 1, when wastewater is initially added, the wastewater liquid level in the mixing barrel 1 is relatively low. By opening the seepage holes 15 on the sleeve 9, the wastewater in the sleeve 9 can be discharged through the seepage holes 15, so that the spiral plate 10 only transports the activated carbon particles upward, and avoids the wastewater carrying the activated carbon particles downward when the wastewater liquid level is low in the initial state, so as to ensure that the activated carbon particles can be smoothly transported upward.

[0028] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
