Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment agent dispensing device. Background Technology

[0002] Wastewater refers to water containing various wastewater and pollutants generated during human production, daily life, and social activities. Wastewater contains various organic and inorganic substances, microorganisms, and heavy metals, which pose certain hazards to the environment and human health. Wastewater treatment agents are used to remove pollutants and odors from wastewater and to flocculate impurities within the wastewater, achieving solid-liquid separation.

[0003] A Chinese patent with publication number CN118458855B discloses a wastewater treatment agent spreading device, including a wastewater treatment tank. A movable mounting frame is symmetrically arranged on both sides of the wastewater treatment tank. A fixed housing is located above the wastewater treatment tank, and a spreading mechanism is located below the fixed housing. A drive-reset mechanism is installed below the spreading mechanism. A vibration-shaking powder mechanism is located on one side of the movable inner housing. The device uses crushing hammers to apply the solid powdered wastewater treatment agent, making it easier and more evenly contact the pollutants in the wastewater. The vibration-shaking powder mechanism prevents the wastewater treatment agent from accumulating on the filter screen. Furthermore, the design of the spreading mechanism and the drive-reset mechanism working together avoids repeated spreading of the treatment agent in the same area, preventing over-dosing.

[0004] In existing technologies, the spreading mechanism, which includes a collection hopper, a main collection pipe, a distribution collection pipe, and a spreading disc, is a fixed structure. Therefore, the amount of wastewater treatment agent spread can be controlled by the speed of movement. When more wastewater treatment agent is needed, the spreading mechanism moves more slowly, reducing the spreading efficiency.

[0005] Therefore, a wastewater treatment agent application device is proposed to address the above problems. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the problem of inconvenience in quickly controlling the amount of wastewater treatment machine spreading in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model provides a wastewater treatment agent spreading device.

[0008] In one embodiment of this utility model, a sewage treatment tank is included. Two medicine storage tanks are symmetrically arranged inside the sewage treatment tank. A moving mechanism is provided above the two medicine storage tanks, and a dispensing mechanism is provided at the bottom of the two medicine storage tanks. The dispensing mechanism includes side plates fixed to the bottom side walls of the two medicine storage tanks. A third motor is fixed to the bottom of each side plate, and a gear is fixed to the output shaft of each third motor. A turntable is rotatably connected to the bottom of each medicine storage tank. A gear ring is fixed to the outer wall of each turntable, and the gear meshes with adjacent gear rings. Four through holes are arranged circumferentially on each turntable. Four discharge ports are arranged circumferentially on the bottom of each medicine storage tank, and the center of the discharge port and the center of the through hole are on the same circle. The number of teeth on the gear ring is four times the number of teeth on the gear.

[0009] In one embodiment of this utility model, two electric slide rails are symmetrically fixed to the two side walls at the top of the sewage treatment tank. A slider is slidably connected to the top of each of the two electric slide rails, and a fixed plate is fixed to the top of each slider. The moving mechanism is located between the two fixed plates.

[0010] In one embodiment of this utility model, the moving mechanism includes a bidirectional ball screw rotatably connected to two fixed plates via bearings. Two moving plates are symmetrically threaded onto the bidirectional ball screw. A first motor is fixedly connected to the fixed plate, and the output shaft of the first motor is fixedly connected to one end of the bidirectional ball screw.

[0011] In one embodiment of this utility model, the top of each medicine storage box is fixedly connected to the bottom of the moving plate by two connecting plates; the top of each medicine storage box is connected to a feed hopper; each moving plate has an opening, and a second motor is fixedly connected to each opening, and a connecting rod is fixedly connected to the output shaft of each second motor, and the connecting rod is rotatably connected to the medicine storage box by bearings.

[0012] In one embodiment of this utility model, a stirring rod is fixedly connected to the bottom of each connecting rod, and multiple stirring paddles are installed on each stirring rod.

[0013] In one embodiment of this utility model, filter plates are fixedly connected to the inner wall of the medicine storage box, the connecting rod is rotatably connected to the filter plate through a bearing, and two scrapers are fixedly connected to the outer wall of the connecting rod. One of the scrapers has a rolling roller rotatably connected to its bottom through a roller shaft, and the bottom of the rolling roller is in contact with the surface of the filter plate; the bottom of the other scraper is in contact with the surface of the filter plate.

[0014] In one embodiment of this utility model, a U-shaped frame is fixedly connected to the bottom end of each connecting rod, and the bottom of the U-shaped frame contacts the bottom of the medicine storage box.

[0015] In one embodiment of this utility model, two guide rods are fixedly connected between the two fixed plates, and the movable plates are slidably connected on the two guide rods.

[0016] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0017] The wastewater treatment agent dispensing device of this utility model utilizes the cooperation of gears, a gear ring, a discharge port, and a through hole. When a third motor is activated, its output shaft drives the gears to rotate, which in turn drives the gear ring to rotate, which in turn drives a turntable to rotate. During the rotation of the turntable, the through hole initially misaligns with the discharge port. As the turntable rotates, the through hole and discharge port connect until they completely overlap, at which point the discharge volume is maximized. The diameter of the through hole aligning with the discharge port is controlled according to the degree of wastewater pollution, facilitating rapid control of the dispensing amount.

[0018] This utility model discloses a wastewater treatment agent dispensing device. Through the cooperation of a connecting rod, scraper, roller, and U-shaped frame, the device works as follows: By activating a second motor, the second motor drives the connecting rod to rotate via its output shaft. The connecting rod then drives the stirring rod to rotate, which in turn drives the stirring paddle to rotate. The stirring paddle stirs the dispensed wastewater treatment agent, achieving simultaneous dispensing and mixing. During rotation, the connecting rod drives the scrapers on both sides to rotate, quickly scraping and filtering the wastewater treatment agent on the filter plates. This prevents the agent from accumulating in the storage tank, which would hinder dispensing. It also filters large particles of the agent. The large particles remaining on the filter plates are crushed by the roller and then scraped off by the scraper. The cooperation of the scraper and roller facilitates efficient use of the wastewater treatment agent. Simultaneously, the rotating connecting rod drives the U-shaped frame to rotate, quickly pushing the wastewater treatment agent at the bottom of the storage tank to the discharge port for dispensing, achieving rapid dispensing.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1-5 As shown, this utility model discloses a wastewater treatment agent dispensing device, comprising a wastewater treatment tank 1. Two storage tanks 8 are symmetrically arranged inside the wastewater treatment tank 1. A moving mechanism is provided above the two storage tanks 8, and a dispensing mechanism is provided at the bottom of the two storage tanks 8. The dispensing mechanism includes side plates 19 fixed to the bottom side walls of the two storage tanks 8. A third motor 20 is fixed to the bottom of each side plate 19, and a gear 18 is fixed to the output shaft of each third motor 20. A turntable 15 is rotatably connected to the bottom of each storage tank 8. A gear ring 16 is fixed to the outer wall of each turntable 15, and the gear 18 meshes with adjacent gear rings 16. Four through holes 17 are arranged circumferentially on each turntable 15. Four discharge ports 22 are arranged circumferentially on the bottom of each storage tank 8, and the center of each discharge port 22 is on the same circle as the center of the through holes 17. The number of teeth on the gear ring 16 is four times the number of teeth on the gear 18.

[0028] During operation, to address the issue of inconvenient and rapid control of the amount of wastewater treatment agent applied, the dosage of the wastewater treatment agent needs to be calculated based on the degree of wastewater contamination before application. The wastewater treatment agent is then placed in the storage tank 8 via the feed hopper 14. The third motor 20 is then activated, and its output shaft drives the gear 18 to rotate. The gear 18 then drives the gear ring 16, which in turn drives the turntable 15. During rotation, the through-hole 17 initially aligns with the discharge port 22. As the turntable 15 rotates, the through-hole 17 connects with the discharge port 22 until they completely overlap, at which point the discharge volume is at its maximum. The diameter of the overlap between the through-hole 17 and the discharge port 22 is controlled according to the degree of wastewater contamination, facilitating rapid control of the application amount. Furthermore, the number of teeth on the gear ring 16 is four times the number of teeth on the gear 18, further facilitating control of the overlap diameter between the through-hole 17 and the discharge port 22.

[0029] Furthermore, such as Figure 1 As shown, two electric slide rails 2 are symmetrically fixed to the two side walls at the top of the sewage treatment tank 1. A slider 3 is slidably connected to the top of each of the two electric slide rails 2. A fixed plate 11 is fixed to the top of each slider 3. The moving mechanism is located between the two fixed plates 11.

[0030] During operation, the electric slide rail 2 is set up to facilitate the movement of the storage tank 8 along the length of the sewage treatment tank 1, so as to achieve uniform spraying of sewage treatment agent in the length direction.

[0031] Furthermore, such as Figure 3 As shown, the moving mechanism includes a bidirectional ball screw 4 rotatably connected to two fixed plates 11 via bearings. Two moving plates 7 are symmetrically threaded onto the bidirectional ball screw 4. A first motor 6 is fixedly connected to the fixed plate 11, and the output shaft of the first motor 6 is fixedly connected to one end of the bidirectional ball screw 4.

[0032] During operation, the bidirectional ball screw 4 facilitates the movement of the storage tank 8 along the width of the sewage treatment tank 1, enabling the uniform dispensing of sewage treatment agent in the width direction. By activating the first motor 6, the first motor 6 drives the bidirectional ball screw 4 to rotate via its output shaft. The bidirectional ball screw 4 then drives the moving plate 7 to move in the opposite direction, which in turn drives the storage tank 8 to move in the opposite direction, thus achieving the function of rapid and uniform dispensing of sewage treatment agent.

[0033] Furthermore, such as Figure 2 and Figure 3As shown, the top of each medicine storage box 8 is fixed to the bottom of the moving plate 7 by two connecting plates 13; the top of each medicine storage box 8 is connected to a feed hopper 14; each moving plate 7 has an opening, and a second motor 12 is fixedly connected to each opening. The output shaft of the second motor 12 is fixedly connected to a connecting rod 26, and the connecting rod 26 is rotatably connected to the medicine storage box 8 by bearings.

[0034] During operation, the connecting plate 13 facilitates the reciprocating motion of the moving plate 7 to control the storage tank 8, the feeding hopper 14 facilitates the addition of wastewater treatment agent, and the connecting rod 26 facilitates the mixing function.

[0035] Furthermore, such as Figure 3 As shown, each of the connecting rods 26 has a stirring rod 9 fixedly connected to its bottom, and each of the stirring rods 9 has a plurality of stirring paddles 10 installed on it.

[0036] During operation, by setting the stirring paddle 10 and turning on the second motor 12, the second motor 12 drives the connecting rod 26 to rotate through the output shaft. The connecting rod 26 drives the stirring rod 9 to rotate, and the stirring rod 9 drives the stirring paddle 10 to rotate. The stirring paddle 10 stirs the sprayed sewage treatment agent, realizing the function of stirring and mixing while playing.

[0037] Furthermore, such as Figure 2 and Figure 5 As shown, filter plates 23 are fixedly connected to the inner wall of the medicine storage box 8. The connecting rod 26 is rotatably connected to the filter plate 23 through a bearing. Two scrapers 24 are fixedly connected to the outer wall of the connecting rod 26. The bottom of one of the scrapers 24 is rotatably connected to a rolling roller 25 through a roller shaft. The bottom of the rolling roller 25 is in contact with the surface of the filter plate 23. The bottom of the other scraper 24 is in contact with the surface of the filter plate 23.

[0038] During operation, as the connecting rod 26 rotates, it drives the scrapers 24 on both sides to rotate. The scrapers 24 quickly scrape and filter the wastewater treatment agent on the filter plate 23, preventing the wastewater treatment agent from accumulating in the storage tank 8 and making it inconvenient to discharge. On the other hand, it filters large particles of wastewater treatment agent. The large particles of wastewater treatment agent left on the filter plate 23 are crushed by the rotating roller 25 and then scraped off by the scraper 24. The cooperation between the scraper 24 and the roller 25 facilitates the efficient use of wastewater treatment agent.

[0039] Furthermore, such as Figure 2 As shown, each of the connecting rods 26 has a U-shaped frame 21 fixed to its bottom end, and the bottom of the U-shaped frame 21 is in contact with the bottom of the medicine storage box 8.

[0040] During operation, when the connecting rod 26 rotates, it drives the U-shaped frame 21 to rotate. The U-shaped frame 21 quickly pushes the sewage treatment agent at the bottom of the medicine storage tank 8 to the discharge port for spreading, thus achieving the function of rapid material discharge.

[0041] Furthermore, such as Figure 3 As shown, two guide rods 5 are fixedly connected between the two fixed plates 11, and the movable plates 7 are slidably connected on the two guide rods 5.

[0042] During operation, the movable plate 7 slides on the guide rod 5 while moving, and the guide rod 5 limits the movement of the movable plate 7 in the horizontal direction.

[0043] Working Principle: To address the issue of inconvenient and rapid control of the amount of wastewater treatment agent applied, the dosage of the wastewater treatment agent needs to be calculated based on the degree of pollution of the wastewater before application. The wastewater treatment agent is placed in the storage tank 8 through the feed hopper 14. Then, the third motor 20 is turned on, and the output shaft of the third motor 20 drives the gear 18 to rotate. The gear 18 drives the gear ring 16 to rotate, which in turn drives the turntable 15 to rotate. During the rotation of the turntable 15, the through hole 17 initially offsets from the discharge port 22. As the turntable 15 rotates, the through hole 17 and the discharge port 22 become connected until the through hole 17 and the discharge port 22 are completely aligned, at which point the discharge volume is at its maximum. The diameter of the alignment between the through hole 17 and the discharge port 22 is controlled according to the degree of pollution of the wastewater, facilitating rapid control of the application amount of the wastewater treatment agent. Furthermore, the number of teeth on the gear ring 16 is four times the number of teeth on the gear 18, which also facilitates control of the alignment between the through hole 17 and the discharge port 22.

[0044] By setting up an electric slide rail 2, it is easy to control the movement of the storage tank 8 along the length direction of the sewage treatment tank 1, so as to achieve uniform dispensing of sewage treatment agent in the length direction. By setting up a bidirectional ball screw 4, it is easy to control the movement of the storage tank 8 along the width direction of the sewage treatment tank 1, so as to achieve uniform dispensing of sewage treatment agent in the width direction. By turning on the first motor 6, the first motor 6 drives the bidirectional ball screw 4 to rotate through the output shaft. The bidirectional ball screw 4 drives the moving plate 7 to move in the opposite direction. The moving plate 7 drives the storage tank 8 to move in the opposite direction, so as to achieve the function of rapid and uniform dispensing of sewage treatment agent.

[0045] By activating the second motor 12, the second motor 12 drives the connecting rod 26 to rotate via its output shaft. The connecting rod 26 then drives the stirring rod 9 to rotate, which in turn drives the stirring paddle 10 to rotate. The stirring paddle 10 stirs the sprayed wastewater treatment agent, achieving the function of mixing while spraying. During the rotation of the connecting rod 26, the connecting rod 26 drives the scrapers 24 on both sides to rotate. The scrapers 24 quickly scrape and filter the wastewater treatment agent on the filter plate 23, preventing the wastewater treatment agent from accumulating in the storage tank 8 and making it inconvenient to discharge. On the other hand, it filters large particles of wastewater treatment agent. The large particles of wastewater treatment agent left on the filter plate 23 are crushed by the rotating roller 25 and then scraped off by the scrapers 24. The cooperation between the scrapers 24 and the roller 25 facilitates the efficient use of the wastewater treatment agent. When the connecting rod 26 rotates, it drives the U-shaped frame 21 to rotate. The U-shaped frame 21 quickly pushes the wastewater treatment agent at the bottom of the storage tank 8 to the discharge port for spraying, achieving the function of rapid discharge.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
