Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an automatic wastewater coagulant dosing device. Background Technology

[0002] Wastewater coagulants are chemical agents used in wastewater treatment processes. Their main function is to cause suspended solids, colloids, and soluble pollutants in wastewater to aggregate into larger flocs through adsorption, bridging, and compression of the electric double layer, thereby achieving solid-liquid separation and purifying the water. Coagulants typically include inorganic coagulants (such as aluminum sulfate and polyaluminum chloride) and organic coagulants (such as polyacrylamide). They have wide applications in wastewater treatment, effectively removing pollutants such as turbidity, color, heavy metals, and organic matter from water, and are an indispensable and important part of water treatment processes.

[0003] In current wastewater treatment processes, granular wastewater coagulants are widely used, typically added directly to the wastewater and then mixed using a stirring mechanism. However, this mixing method is inefficient and fails to meet the demands of high-efficiency wastewater treatment. On the other hand, while powdered wastewater coagulants can accelerate mixing to some extent, their physical properties make precise quantitative dosing difficult to achieve in practice, thus affecting the effectiveness and stability of wastewater treatment. Summary of the Invention

[0004] One objective of this invention is to provide an automatic wastewater coagulant dosing device. This invention addresses the problem of low efficiency in the mixing method mentioned above, which makes it difficult to meet the needs of efficient wastewater treatment. On the other hand, although using powdered wastewater coagulants can accelerate the mixing efficiency to a certain extent, their physical properties make it difficult to achieve precise quantitative dosing in actual operation, thus affecting the effectiveness and stability of wastewater treatment.

[0005] An automatic wastewater coagulant dosing device according to an embodiment of the present invention includes:

[0006] A uniform feeding mechanism, installed on the surface of a fixed rod, is used to ensure that granular wastewater coagulant is uniformly fed into the crushing mechanism for crushing. The uniform feeding mechanism includes a rotating disk, a top rod, and an insert rod. The rotating disk is connected to the output end of a drive motor via a transmission shaft. A circular groove is formed on the surface of the rotating disk. A sliding groove is provided at the lower end of the top rod. A slider is slidably connected inside the sliding groove. The slider is fixedly connected to the surface of the rotating disk. The insert rod is fixedly connected to the upper end of a connecting rod. A sliding rod is fixedly connected to the lower end of the connecting rod. The sliding rod is slidably connected inside the circular groove. The connecting rod is rotatably connected to the surface of the fixed rod. An arc-shaped groove is formed at one end of the insert rod.

[0007] The anti-clogging mechanism is installed on the lower surface of the feed hopper to vibrate the inner wall of the feed hopper and prevent the granular sewage coagulant from clogging.

[0008] The crushing mechanism, installed inside the outer casing, is used to crush the sewage coagulant entering the outer casing into powder so that it can react with the sewage more quickly. The crushing mechanism includes a roller shaft and a crushing roller. The crushing roller and the roller assembly are rotatably connected inside the outer casing. An impact plate is fixedly connected to the upper part of the inner wall of the outer casing. A baffle is fixedly connected to the side surface of the roller shaft. A crushing groove is opened on the side surface of the crushing roller.

[0009] Preferably, a feeding pipe is fixedly connected to the upper surface of the fixed rod, and a feeding hopper is fixedly connected to one side of the feeding pipe. Both the feeding pipe and the feeding hopper are filled with granular sewage coagulant.

[0010] Preferably, a first rotating rod is rotatably connected to the lower surface of the fixed rod, and a second rotating rod is rotatably connected to one side surface of the connecting rod, with a spring structure provided between the first rotating rod and the second rotating rod.

[0011] Preferably, a discharge hopper is fixedly connected through the upper part of one side surface of the feeding pipe, and the other end of the discharge hopper is inserted into the inlet of the outer box.

[0012] Preferably, the anti-blocking mechanism includes a collision block, which is movably connected to the side surface of the rotating shaft via an elastic component. One end of the rotating shaft is fixedly connected to a first gear, which is rotatably connected to the side surface of the feeding tube via the rotating shaft and the connecting shaft.

[0013] Preferably, the first gear, the rotating shaft, and the collision block are each provided in two sets, the two sets of the first gear mesh with each other, and the two sets of the collision blocks and the rotating shaft are respectively provided on the two side surfaces of the feed hopper.

[0014] Preferably, a second toothed block is fixedly connected to one end of the rotating shaft, and a first toothed block is fixedly connected to the side surface of the transmission shaft. The rotating shaft and the transmission shaft are connected to each other through the first toothed block, the second toothed block, and the transmission belt.

[0015] Preferably, the lower surface of the outer casing has a through-hole for directly introducing the pulverized powdered wastewater coagulant into the wastewater for mixing and treatment.

[0016] Preferably, a fourth gear is fixedly connected to one end of the roller shaft, and a second gear is fixedly connected to one end of the crushing roller. The second gear and the fourth gear mesh with each other through a third gear.

[0017] Preferably, a small gear is fixedly connected to one side of the second gear, and a large gear is fixedly connected to the side surface of the transmission shaft. The large gear and the small gear mesh with each other. The large gear is driven by a drive motor to rotate, thereby causing the small gear, the second gear, the third gear and the fourth gear to rotate synchronously, thus achieving the purpose of rotating the roller shaft and the crushing roller.

[0018] The beneficial effects of this invention are:

[0019] This invention utilizes a pulverizing mechanism. After granular wastewater coagulant enters the pulverizing mechanism via a uniform feeding mechanism, a drive motor drives a small gear to rotate at high speed via a large gear. The small gear drives a second gear, which in turn drives a pulverizing roller. Simultaneously, a third gear drives a fourth gear and a roller shaft. Once inside the outer casing, the granular wastewater coagulant first impacts and pulverizes the baffle plate, causing it to collide with an impact plate. Subsequently, the coagulant is guided by the inner wall of the outer casing to the surface of the pulverizing roller at the bottom of the outer casing. Through the mutual compression between the pulverizing roller and the inner wall of the outer casing, and the compression effect of the pulverizing groove, the coagulant is further pulverized after the initial impact. Finally, it falls into the wastewater through the discharge port, where it mixes thoroughly with the wastewater, accelerating wastewater treatment. This significantly improves the dissolution rate of the wastewater coagulant and the wastewater treatment efficiency, while reducing energy consumption and simplifying the treatment process.

[0020] This invention utilizes a uniform feeding mechanism. As granular wastewater coagulant enters the feeding pipe through the feed hopper, a drive motor rotates the transmission shaft and rotating disk. When the sliding rod slides to a larger section of the circular groove, the spring structure pushes outward to reset, causing the upper end of the connecting rod to rotate inward. The insert at the upper end of the connecting rod then compresses the coagulant into the feeding pipe, pushing the previous granular wastewater coagulant upward through the arc-shaped groove. Simultaneously, the rotation of the rotating disk pulls the sliding groove and push rod downward via a slider, allowing the next granular wastewater coagulant to enter the feeding pipe through the inclined surface of the feed hopper. This ensures that the uppermost granular coagulant in the feeding pipe... Granular wastewater coagulant enters the outer casing through the discharge hopper for crushing. When the sliding rod rotates to the smaller space of the circular groove, the spring structure is compressed, causing the insert at the upper end of the connecting rod to slide outward. At the same time, the top rod slides upward, pushing up the lowest granular wastewater coagulant inside the feeding pipe, making room for the next granular wastewater coagulant to enter the feeding pipe from the inlet hopper. The uniform and continuous rotation of the rotating disc ensures the uniform feeding of granular wastewater coagulant, ensuring the stability and efficiency of the crushing process, avoiding blockage and material interruption, thereby improving the overall effect of wastewater treatment and the reliability of equipment operation.

[0021] This invention utilizes an anti-clogging mechanism. During use, a large amount of granular wastewater coagulant is poured into the feed hopper. As the granular wastewater coagulant flows into the feeding pipe through the feed hopper's pipe, a drive motor rotates the first toothed block. The first toothed block, through a transmission belt, drives the second toothed block, the first gear, and the rotating shaft to rotate. Simultaneously, the rotating shaft causes the collision block to impact the two side surfaces of the feed hopper, causing the side walls of the feed hopper to vibrate. This effectively prevents the granular wastewater coagulant from clogging at the feed hopper outlet, ensuring smooth material flow, improving feeding efficiency, reducing equipment failures and downtime, and thus enhancing the stability and reliability of the wastewater treatment equipment.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0032] refer to Figure 1-7 An automatic wastewater coagulant dosing device includes the following embodiments:

[0033] Example 1:

[0034] An automatic wastewater coagulant dosing device includes a uniform feeding mechanism 1, mounted on the surface of a fixed rod 106, for uniformly feeding granular wastewater coagulant into a crushing mechanism 3 for crushing. The uniform feeding mechanism 1 includes a rotating disk 103, a top rod 110, and an insert rod 114. The rotating disk 103 is connected to the output end of a drive motor 101 via a transmission shaft 102. A circular groove 104 is formed on the surface of the rotating disk 103. A sliding groove 111 is provided at the lower end of the top rod 110. A slider 105 is slidably connected inside the sliding groove 111 and is fixedly connected to the surface of the rotating disk 103. The insert rod 114 is fixedly connected to the upper end of a connecting rod 113, and a sliding rod 112 is fixedly connected to the lower end of the connecting rod 113. The sliding rod 112 is slidably connected to the circular groove. Inside 104, connecting rod 113 is rotatably connected to the surface of fixed rod 106, and one end of insert rod 114 has an arc-shaped groove 115; a feeding pipe 108 is fixedly connected to the upper surface of fixed rod 106, and a feeding hopper 107 is fixedly connected to one side of feeding pipe 108. Granular sewage coagulant is placed inside both feeding pipe and feeding hopper 107. A first rotating rod 116 is rotatably connected to the lower surface of fixed rod 106, and a second rotating rod 117 is rotatably connected to one side of connecting rod 113. A spring structure 118 is provided between the first rotating rod 116 and the second rotating rod 117. A discharge hopper 109 is fixedly connected through the upper part of one side of feeding pipe 108, and the other end of discharge hopper 109 is inserted into the inlet 312 of outer casing 301. In the uniform feeding mechanism 1, granular wastewater coagulant enters the feeding pipe 108 through the feed hopper 107. The drive motor 101 drives the transmission shaft 102 and the rotating disk 103 to rotate. When the slide rod 112 slides to the larger space section of the circular groove 104, the spring structure 118 pushes outward to reset, causing the upper end of the connecting rod 113 to rotate inward. The insertion rod 114 at the upper end of the connecting rod 113 squeezes the coagulant into the feeding pipe 108. The arc-shaped groove 115 pushes the previous granular wastewater coagulant upward. Simultaneously, the rotation of the rotating disk 103 pulls the slide groove 111 and the push rod 110 downward through the slider 105, allowing the next granular wastewater coagulant to enter the feeding pipe 108 through the inclined surface of the feed hopper 107. The granular sewage coagulant at the top of the feed pipe 108 enters the outer casing 301 through the discharge hopper 109 for crushing. When the slide rod 112 rotates to the smaller space of the circular groove 104, the spring structure 118 is compressed, causing the insert rod 114 at the upper end of the connecting rod 113 to slide outward. At the same time, the top rod 110 slides upward, pushing up one granular sewage coagulant at the bottom of the feed pipe 108, making room for the next granular sewage coagulant to enter the feed pipe 108 from the inlet hopper 107. Through the uniform and continuous rotation of the rotating disk 103, the granular sewage coagulant is fed evenly, ensuring the stability and efficiency of the crushing process, avoiding blockage and material interruption, thereby improving the overall effect of sewage treatment and the reliability of equipment operation.

[0035] Example 2:

[0036] Anti-clogging mechanism 2, installed on the lower surface of feed hopper 107, is used to vibrate the inner wall of feed hopper 107 to prevent clogging of granular sewage coagulant. Anti-clogging mechanism 2 includes collision block 207, which is movably connected to the side surface of rotating shaft 206 via an elastic component. One end of rotating shaft 206 is fixedly connected to a first gear 205, which is rotatably connected to one side surface of feed pipe 108 via rotating shaft 206 and connecting shaft 204. Two sets of first gear 205, rotating shaft 206, and collision block 207 are provided, and the two sets of first gear 205 mesh with each other. Two sets of collision blocks 207 and rotating shaft 206 are respectively provided on the two side surfaces of feed hopper 107. One end of rotating shaft 206 is fixedly connected to a second tooth block 202, and the side surface of transmission shaft 102 is fixedly connected to a first tooth block 201. Rotating shaft 206 and transmission shaft 102 are connected by the first tooth block. 201, the second toothed block 202 and the transmission belt 203 are interconnected. Through the anti-blocking mechanism 2, when a large amount of granular sewage coagulant is poured into the feed hopper 107, the granular sewage coagulant enters the feeding pipe 108 through the pipe of the feed hopper 107. During this process, the drive motor 101 drives the first toothed block 201 to rotate. The first toothed block 201 drives the second toothed block 202, the first gear 205 and the rotating shaft 206 to rotate through the transmission belt 203. At the same time, the rotating shaft 206 drives the collision block 207 to hit the two side surfaces of the feed hopper 107, causing the two side walls of the feed hopper 107 to vibrate. This effectively prevents the granular sewage coagulant from blocking at the outlet of the feed hopper 107, ensures smooth material flow, improves feeding efficiency, reduces equipment failure and downtime, and thus enhances the stability and reliability of the sewage treatment equipment.

[0037] Example 3:

[0038] The pulverizing mechanism 3, installed inside the outer casing 301, is used to pulverize the sewage coagulant entering the outer casing 301 into powder form so that it can react more quickly with the sewage. The pulverizing mechanism 3 includes a roller shaft 310 and a pulverizing roller 308. The pulverizing roller 308 and the roller assembly are rotatably connected inside the outer casing 301. An impact plate 302 is fixedly connected to the upper part of the inner wall of the outer casing 301. A baffle 311 is fixedly connected to the side surface of the roller shaft 310. A pulverizing groove 309 is opened on the side surface of the pulverizing roller 308. A through-hole is opened on the lower surface of the outer casing 301 for the pulverized sewage coagulant to be directly introduced into the sewage for mixing. The discharge port 313 is connected to a fourth gear 307 at one end of the roller shaft 310, and a second gear 305 is fixedly connected to one end of the crushing roller 308. The second gear 305 and the fourth gear 307 mesh with each other through a third gear 306. A small gear 304 is fixedly connected to one side of the second gear 305, and a large gear 303 is fixedly connected to the side surface of the drive shaft 102. The large gear 303 and the small gear 304 mesh with each other. The drive motor 101 drives the large gear 303 to rotate, thereby causing the small gear 304, the second gear 305, the third gear 306, and the fourth gear 307 to rotate synchronously. The roller shaft 310 and the crushing roller 308 rotate through the crushing mechanism 3. After the granular sewage coagulant enters the crushing mechanism 3 through the uniform feeding mechanism 1, the drive motor 101 drives the small gear 304 to rotate at high speed through the large gear 303. The small gear 304 drives the second gear 305 to rotate the crushing roller 308. At the same time, the third gear 306 drives the fourth gear 307 and the roller shaft 310 to rotate. After the granular sewage coagulant enters the outer box 301, it first drives the baffle 311 to rotate through the roller shaft 310, which then displaces the sewage that falls on the surface of the baffle 311. The coagulant impacts the impact plate 302 to achieve initial impact crushing. Subsequently, the sewage coagulant falls through the guide wall of the outer box 301 onto the surface of the crushing roller 308 at the lower part of the outer box 301. Through the mutual squeezing action between the crushing roller 308 and the inner wall of the outer box 301 and the squeezing action of the crushing groove 309, the sewage coagulant after the initial impact crushing is further crushed. Finally, it falls into the sewage through the discharge port 313, mixes thoroughly with the sewage, thereby accelerating the sewage treatment, significantly improving the dissolution rate of the sewage coagulant and the sewage treatment efficiency, while reducing energy consumption and simplifying the treatment process.

[0039] In operation, the operator starts the drive motor 101, and the equipment enters the preparation state. Simultaneously, a large amount of granular wastewater coagulant is poured into the feed hopper 107. The drive motor 101 drives the rotating disk 103 to rotate at a constant speed via the transmission shaft 102. The circular groove 104 on the surface of the rotating disk 103 causes the slider 105 to slide. The slider 105 is fixedly connected to the rotating disk 103, simultaneously causing the sliding groove 111 and the push rod 110 to move downwards. When the slide rod 112 slides to the larger space section of the circular groove 104, the spring structure 118 pushes outwards to reset, causing the upper end of the connecting rod 113 to rotate inwards. The insert rod 114 at the upper end of the connecting rod 113 presses into the feed pipe 108, pushing the previous granular wastewater coagulant upwards through the arc-shaped groove 115. At the same time, the next granular wastewater coagulant enters the feed pipe 108 through the inclined surface of the feed hopper 107. The granular wastewater coagulant at the top of the feed pipe 108 enters the outer casing 301 through the discharge hopper 109, ready for crushing. When the slide rod 112 rotates into the smaller space of the circular groove 104, the spring structure 118 is compressed, causing the insert rod 114 at the upper end of the connecting rod 113 to slide outward. At the same time, the top rod 110 slides upward, pushing up one granular wastewater coagulant at the bottom of the feed pipe 108 to make room for the next particle. Through the uniform and continuous rotation of the rotating disk 103, the granular wastewater coagulant is fed evenly and continuously. Simultaneously, the drive motor 101 drives the first toothed block 201 to rotate. The first toothed block 201 drives the second toothed block 202, the first gear 205, and the rotating shaft 206 to rotate via the transmission belt 203. As the rotating shaft 206 rotates, it drives the collision block 207 to impact the two side surfaces of the feed hopper 107, causing the two side walls of the feed hopper 107 to vibrate. This effectively prevents the granular sewage coagulant inside the feed hopper 107 from clogging at the outlet, ensuring smooth material flow. Subsequently, the drive motor 101 drives the large gear 303 to rotate at a certain speed. The large gear 303 drives the small gear 304, making the rotation speed of the small gear 304 greater than that of the large gear 303. This causes the crushing roller 308, the third gear 306, and the roller shaft 310 to rotate uniformly at a high speed. After the granular sewage coagulant enters the outer box 301, it first drives the baffle 311 to rotate via the roller shaft 310, causing the sewage coagulant falling on the surface of the baffle 311 to impact the impact plate 302, achieving initial impact crushing. Subsequently, the wastewater coagulant is guided by the inner wall of the outer casing 301 and falls onto the surface of the crushing roller 308 at the lower part of the outer casing 301. Through the mutual squeezing action between the crushing roller 308 and the inner wall of the outer casing 301, as well as the squeezing action of the crushing tank 309, the wastewater coagulant, after its initial impact crushing, is further crushed. Finally, the crushed powdered wastewater coagulant falls into the wastewater through the discharge port 313, mixes thoroughly with the wastewater, and accelerates the wastewater treatment process.The entire device ensures the stability and efficiency of the crushing process through the uniform feeding mechanism 1, avoiding blockage and material interruption; the anti-blocking mechanism 2 improves the feeding efficiency and reduces equipment failure and downtime; the high-efficiency crushing significantly improves the dissolution rate of sewage coagulant and sewage treatment efficiency, while reducing energy consumption, simplifying the treatment process, and enhancing the overall stability and reliability of sewage treatment equipment, realizing a high-efficiency and automatic sewage coagulant dosing process.
