Description

Technical Field

[0001] This utility model relates to the field of textile wastewater treatment technology, and in particular to a quantitative dosing device for textile wastewater treatment. Background Technology

[0002] With the rapid development of my country's textile industry, textile wastewater pollution has become increasingly prominent. In particular, dyeing and printing wastewater contains a large amount of organic matter that is difficult to degrade, which seriously threatens the safety of the water environment. In order to improve wastewater treatment efficiency, reduce operating costs, and reduce environmental pollution, a quantitative dosing device for textile wastewater treatment is needed.

[0003] A search revealed Chinese patent publication number CN212151666U, which discloses a quantitative dosing device for textile wastewater treatment. The device includes a power mechanism and a storage tank. The power mechanism is located at one end of the storage tank and contains a crankshaft. A connecting rod is connected to the journals at both ends of the crankshaft. Control valves are installed on both the upper and lower end faces of the storage tank. These control valves are connected to the power mechanism via connecting pipes. Each control valve contains a pipe and a transverse groove. A stop plate slides within the groove, with one end connected to a connecting rod inside the power mechanism. This invention effectively achieves quantitative control of the added chemical solution. Furthermore, the storage capacity of the storage tank can be adjusted as needed, effectively expanding the applicability of the dosing device and improving the accuracy of chemical dosing control in textile wastewater treatment. However, each use of this device requires manual rotation of an adjustment button to control the amount of chemical added, making the operation cumbersome and preventing automation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quantitative dosing device for textile wastewater treatment, which aims to improve the problem that the amount of chemical dosing needs to be controlled by manually rotating the adjustment button each time it is used, which is cumbersome and cannot be automated.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quantitative dosing device for textile wastewater treatment, comprising an outer frame, with a storage tank fixedly connected to the top left and right sides of the inner wall of the outer frame, an mounting plate fixedly connected to the top of the inner wall of the outer frame, wastewater pipes provided on the top left and right sides of the outer frame, flow meters connected to the middle of the outer walls of the two wastewater pipes, and the two flow meters fixedly connected to the mounting plate, a discharge pipe fixedly connected to the middle of the rear side of the inner wall of the outer frame, a metering pump fixedly connected to the top of the storage tank, a delivery pipe connected to the top of the metering pump, a solenoid valve connected to the other end of the delivery pipe, and a discharge pipe connected to the other end of the solenoid valve, a controller fixedly connected to the middle of the front side of the outer wall of the mounting plate, a calculation module fixedly connected to the inner wall of the controller, the controller electrically connected to the flow meters, the metering pump and the solenoid valve respectively, a treatment tank provided on the rear side of the outer wall of the outer frame, and a moving mechanism provided at the bottom of the outer frame for moving the outer frame.

[0006] Through the above technical solution: when wastewater flows through the flow meter in the middle of the inlet pipe and is discharged into the treatment tank, the flow meter will measure the amount of wastewater entering in real time. The flow meter transmits the measured flow data to the calculation module in the controller on the mounting plate. Based on the result obtained by the calculation module, the controller controls the air pump on the top of the storage tank to work, so that the medicine is drawn into the delivery pipe. The solenoid valve opens, so that the medicine enters the discharge pipe and is discharged into the treatment tank.

[0007] As a further description of the above technical solution:

[0008] The moving mechanism includes a base frame, which is fixedly connected to the bottom of the outer wall of the outer frame. A motor is fixedly connected to the top center of the base frame, and a gear is fixedly connected to the output end of the motor. Threaded sleeves are rotatably connected to the left and right sides of the bottom of the outer frame. External gear sleeves are fixedly connected to the middle of the outer walls of the two threaded sleeves, and both external gear sleeves mesh with the gear. A threaded rod is threadedly connected to the inner wall of the threaded sleeve. A connecting plate is fixedly connected to the bottom end of the threaded rod. The bottom end of the connecting plate penetrates the base frame. Moving wheels are fixedly connected to the front and rear sides of the bottom of the connecting plate. Support legs are fixedly connected to the four sides of the bottom of the base frame.

[0009] The above technical solution involves a motor driving a gear to rotate, which in turn meshes and drives the threaded sleeve to rotate. Since the bottom end of the connecting plate passes through the base frame and can only move up and down, the rotation of the threaded sleeve causes the threaded rod and the connecting plate to move up and down, thereby changing the distance between the moving wheel and the ground.

[0010] As a further description of the above technical solution:

[0011] The inner walls of both medicine storage boxes are fixedly connected with anti-corrosion layers, and both medicine storage boxes have filling ports on the top rear side. The inner walls of both filling ports are threaded with sealing caps.

[0012] Through the above technical solutions: the anti-corrosion layer can prevent the medicine inside the medicine storage tank from corroding the medicine storage tank, thereby extending the service life of the medicine storage tank; the filling port facilitates the filling of medicine; and the sealing cap can prevent the medicine from evaporating.

[0013] As a further description of the above technical solution:

[0014] Both wastewater pipes have flanges fixedly connected to their outer front ends, and multiple screws are threaded around the outer perimeter of each flange.

[0015] The above technical solution allows for the use of flanges to connect other wastewater pipes, with screw connections facilitating disassembly.

[0016] As a further description of the above technical solution:

[0017] A mounting base is fixedly connected to the top of the controller, and a fault alarm is fixedly connected to the inner wall of the mounting base.

[0018] Through the above technical solution, the fault alarm can sound an alarm when an accident occurs during the operation of the device, reminding staff to check.

[0019] As a further description of the above technical solution:

[0020] A mounting box is fixedly connected to the top front side of the bottom frame, and a spare battery is fixedly connected to the inner wall of the mounting box.

[0021] Through the above technical solution, the backup battery can provide power to other components in the event of an unexpected power outage, preventing the equipment from stopping operation due to power failure and affecting sewage treatment.

[0022] As a further description of the above technical solution:

[0023] The bottom of the outer wall of each of the multiple support legs is provided with a groove, and the inner wall of each of the multiple grooves is fixedly connected with an anti-slip pad.

[0024] As a further description of the above technical solution:

[0025] Through the above technical solution, the anti-slip mat can increase the friction between the supporting leg and the ground, making the device more stable.

[0026] As a further description of the above technical solution:

[0027] The bottom front and rear sides of the discharge pipe are fixedly connected to multi-hole nozzles, and the outer walls of the multi-hole nozzles are provided with reserved holes.

[0028] Through the above technical solution, the liquid medicine can quickly diffuse to the surrounding area through multiple reserved holes, rapidly mix with the wastewater, and improve treatment efficiency.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the calculation module in the controller receives the real-time water flow rate changes detected by the flow meter and calculates the required liquid flow rate. Then, the metering pump is controlled to draw the liquid from the storage tank. At this time, the solenoid valve is in the open state, allowing the liquid to smoothly diffuse into the treatment tank through the discharge pipe and the multi-hole nozzle and mix with the sewage. After the dosing is completed, the controller sends a control signal to control the solenoid valve to close and stop the liquid delivery, thereby achieving automation while ensuring accurate dosing.

[0031] 2. In this utility model, the starting motor drives the gear to rotate, which in turn drives the outer gear sleeve and the threaded sleeve to rotate. The threaded rod and the connecting plate will move up and down according to the rotation direction of the threaded sleeve, thereby driving the moving wheel to move. When the moving wheel contacts the ground and lifts the entire device upward, causing the support leg to leave the ground, the device can be moved by the moving wheel, which improves the convenience of the device.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figure 1 , Figure 2 and Figure 6This utility model provides an embodiment of a quantitative dosing device for textile wastewater treatment, comprising an outer frame 1, with a storage tank 3 fixedly connected to the top left and right sides of the inner wall of the outer frame 1 for storing chemicals; an mounting plate 4 fixedly connected to the top of the inner wall of the outer frame 1 for providing mounting points for other components; wastewater pipes 5 provided on the top left and right sides of the outer frame 1 for connecting to other wastewater discharge pipes; flow meters 6 connected to the middle of the outer walls of the two wastewater pipes 5 for real-time monitoring of water flow velocity; both flow meters 6 fixedly connected to the mounting plate 4; a discharge pipe 12 fixedly connected to the middle of the rear side of the inner wall of the outer frame 1 for discharging chemicals to a designated area; a metering pump 9 fixedly connected to the top of the storage tank 3; and a delivery pipe 10 connected to the top of the metering pump 9 for delivering chemicals. The other end of the medicine pipe 10 is connected to a solenoid valve 11, and the other end of the solenoid valve 11 is connected to a discharge pipe 12. The metering pump 9 is responsible for drawing the medicine liquid at a set rate and delivering it to the discharge pipe 12 through the medicine delivery pipe 10. A controller 7 is fixedly connected to the middle of the front side of the outer wall of the mounting plate 4. A calculation module 8 is fixedly connected to the inner wall of the controller 7. The controller 7 is electrically connected to the flow meter 6, the metering pump 9 and the solenoid valve 11 respectively. The controller 7 receives data from the flow meter 6 and calculates the corresponding medicine liquid flow rate according to the pre-input dosing ratio, thereby controlling the working frequency of the metering pump 9 and the opening and closing state of the solenoid valve 11. A treatment tank 14 is provided on the rear side of the outer wall of the outer frame 1. The treatment tank 14 serves as a container for the reaction between wastewater and medicine liquid. A moving mechanism 2 is provided at the bottom of the outer frame 1. The moving mechanism 2 is used to move the outer frame 1.

[0042] Specifically, the outer frame 1 provides support for the entire device, the storage tank 3 is used to store the medicine, when wastewater flows into the treatment tank 14 through the wastewater pipe 5, the flow meter 6 can detect the change in the wastewater flow rate in the wastewater pipe 5 in real time and send a signal to the controller 7. The calculation module 8 inside the controller 7 quickly calculates the required medicine flow rate based on the received signal value and the preset dosing ratio. The metering pump 9 is electrically connected to the controller 7. The controller 7 can control the metering pump 9 to extract the medicine at the set rate. Based on the result obtained by the calculation module 8, the controller 7 controls the air pump 9 on the top of the storage tank 3 to work. The solenoid valve 11 is controlled by the controller 7 to open or close the medicine flow channel to prevent over-dosing from causing waste and affecting subsequent treatment processes, and to ensure accurate dosing of the medicine. The discharge pipe 12 transports the extracted medicine to the treatment tank 14.

[0043] Reference Figure 1 ,and Figure 5The moving mechanism 2 includes a base frame 201, which is fixedly connected to the bottom of the outer wall of the outer frame 1. The base frame 201 serves to support and install other components. A motor 202 is fixedly connected to the top center of the base frame 201, and a gear 203 is fixedly connected to the output end of the motor 202. Threaded sleeves 204 are rotatably connected to the left and right sides of the bottom of the outer frame 1. External gear sleeves 205 are fixedly connected to the middle of the outer wall of each of the two threaded sleeves 204, and both external gear sleeves 205 mesh with the gears 203. When the motor 202 is started, it drives the gears 203 to rotate. The movement drives the outer gear sleeve 205 and the threaded sleeve 204 to rotate through meshing transmission. The inner wall of the threaded sleeve 204 is threadedly connected to a threaded rod 206. The bottom end of the threaded rod 206 is fixedly connected to a connecting plate 207. The bottom end of the connecting plate 207 passes through the bottom frame 201. The connecting plate 207 is restricted by the bottom frame 201 and can only move up and down. The front and rear sides of the bottom of the connecting plate 207 are fixedly connected to moving wheels 208. The bottom of the bottom of the bottom frame 201 is fixedly connected to support legs 209. In the initial state, the moving wheels 208 do not contact the ground.

[0044] Specifically, the bottom frame 201 is fixed to the bottom of the outer wall of the outer frame 1, serving to support and install other components. The rotation of the gear 203 will mesh with and drive the rotation of the outer gear sleeves 205 on the left and right sides, thereby causing the threaded sleeve 204 to start rotating. Since the threaded rod 206 is fixedly connected to the connecting plate 207, and the bottom end of the connecting plate 207 passes through the bottom frame 201 and can only move up and down, when the threaded sleeve 204 rotates, it drives the threaded rod 206 and the connecting plate 207 to move up and down, thereby driving the moving wheel 208 to move up and down. When the moving wheel 208 moves downward to contact the ground until the support leg 209 leaves the ground, the entire device can be moved by the moving wheel 208.

[0045] Reference Figure 1 , Figure 4 and Figure 3 The inner walls of both medicine storage tanks 3 are fixedly connected with anti-corrosion layers 25, which can prevent the stored medicine from corroding the inner walls of the medicine storage tanks 3. Both medicine storage tanks 3 have filling ports 15 on the top rear side, and the inner walls of both filling ports 15 are threaded with sealing caps 16. The sealing caps 16 can ensure the sealing of the filling ports 15 after the medicine is added. The front ends of the outer walls of both wastewater pipes 5 are fixedly connected with flanges 17. Multiple screws 18 are threaded around the outer walls of the flanges 17. The flanges 17 and the multiple screws 18 around them are mainly used to connect the sewage pipeline system. The top of the controller 7 is fixedly connected with a mounting base 19, and the inner wall of the mounting base 19 is fixedly connected with a fault alarm 20. The fault alarm 20 can issue an alarm signal in time when the device malfunctions.

[0046] Specifically, the anti-corrosion layer 25 on the inner wall of the storage tank 3 can prevent the stored agents from corroding the inner wall of the storage tank 3, ensuring the service life of the storage tank 3. The filling port 15 on the top rear side of the storage tank 3 provides a convenient entrance for adding agents into the storage tank 3. The sealing cap 16 can ensure the sealing of the filling port 15 after adding agents, preventing external impurities from entering the storage tank 3 and contaminating the agents, while also preventing the agents from evaporating or leaking. The flange 17 and the multiple screws 18 around it are mainly used to connect the pipeline system for treating sewage. The flange 17 connection method makes the pipeline connection more secure and reliable, and facilitates installation and disassembly. The mounting base 19 provides a stable installation position for the fault alarm 20. The fault alarm 20 can issue an alarm signal in time when the device malfunctions, and the fault alarm 20 will remind the staff to carry out inspection and maintenance, so as to troubleshoot in time and ensure the stable operation of the wastewater treatment quantitative dosing device.

[0047] Reference Figure 1 , Figure 4 and Figure 5 A mounting box 21 is fixedly connected to the top front side of the bottom frame 201. A spare battery 22 is fixedly connected to the inner wall of the mounting box 21. The spare battery 22 can provide temporary power to key components when the device encounters a sudden power outage. Grooves 23 are opened on the bottom of the outer wall of multiple support legs 209. Anti-slip pads 24 are fixedly connected to the inner wall of multiple grooves 23. The anti-slip pads 24 can increase the friction between the support legs 209 and the ground, making the device more stable when placed. A multi-hole nozzle 13 is fixedly connected to the front and rear sides of the bottom of the discharge pipe 12. The multi-hole nozzle 13 has reserved holes 26 on all four sides of its outer wall. Through the reserved holes 26, the agent can flow out in multiple directions and fully contact the wastewater.

[0048] Specifically, the backup battery 22 can provide temporary power to critical components in the event of a sudden power outage, ensuring that the device can continue to operate or stop safely in a short period of time, avoiding uncontrolled reagent addition and data loss due to power outages, and improving the reliability and stability of the device; the groove 23 is used to install the anti-slip pad 24, which can increase the friction between the support leg 209 and the ground, making the device more stable when placed and less prone to movement or shaking due to external forces; the multi-hole nozzle 13 can spray the reagent more evenly into the wastewater, and the reserved holes 26 on the outer wall can spray the reagent in multiple directions, making full contact with the wastewater, improving the mixing effect of the reagent and wastewater, thereby improving the efficiency and quality of wastewater treatment.

[0049] Working principle: When wastewater flows into treatment tank 14 through wastewater pipe 5, flow meter 6 immediately detects the change in water flow and sends a signal to controller 7. The calculation module 8 inside controller 7 quickly calculates the required liquid flow rate based on the received signal value and the preset dosing ratio. Then, it issues a command to start metering pump 9 to pump the liquid from storage tank 3 into delivery pipe 10. At this time, solenoid valve 11 is open, allowing the liquid to pass smoothly through discharge pipe 12 and diffuse through multi-hole nozzle 13 into treatment tank 14 to mix with wastewater, thus achieving wastewater pretreatment. Once the dosing is complete, controller 7 sends a control signal to close solenoid valve 11, stopping the liquid delivery and preventing over-dosing. This avoids waste or affects subsequent processing, thus achieving automated and precise delivery of the medicine. Furthermore, by starting the motor 202, the output of the motor 202 drives the gear 203 to rotate, which in turn drives the outer gear sleeve 205 to rotate, causing the threaded sleeve 204 to start rotating. When the threaded sleeve 204 rotates, the threaded rod 206 and the connecting plate 207 move up and down according to the rotation direction of the threaded sleeve 204. When the moving wheel 208 contacts the ground and lifts the entire device upwards, causing the support leg 209 to leave the ground, the device can move via the moving wheel 208. When it reaches the designated position, the motor 202 is reversed, causing the moving wheel 208 to retract and the support leg 209 to contact the ground, thus achieving fixation.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
