[0003] After searching, it was found that the Chinese patent with publication number CN202222644260.5 disclosed a dosing device for sewage treatment. By setting a partition component, the partition component separates the inner cavity of the dissolving box from the inner cavity of the dosing box. The dissolving and dosing are relatively independent and do not interfere with each other, which can achieve continuous addition of liquid medicine, and the liquid medicine is more evenly distributed, thereby improving the water treatment efficiency. It solves the problem that the existing device cannot add medicine to sewage when dissolving medicine, cannot dissolve medicine when adding medicine to sewage, cannot continuously add liquid medicine to sewage, and has low treatment efficiency.
[0004] However, when the device is used to dose solid agents such as coagulants and flocculants, since the dosing port is fixed at the top, the dosed agents will fall in one place, and it may happen that some places are fully dosed and others are insufficiently dosed. The dosing uniformity is poor, and incompletely dissolved agents may flow out through the connecting pipe at the bottom of the partition plate, resulting in insufficient agent concentration in the dissolving area. In order to solve the above problems, we propose an independent dosing device for water purification equipment. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] The utility model is provided with a medicine distributing mechanism, and when the rotating shaft drives the stirring member to rotate, the medicine distributing mechanism can evenly put medicine into the medicine dissolving box, so that the effect of dissolving the medicine is better.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1-6The utility model provides a technical solution: an independent dosing device for water treatment equipment, including a drug dissolving box 1, a rotating shaft 2 is rotatably mounted in the drug dissolving box 1, the rotating shaft 2 is fixedly connected to the motor output end at the top of the drug dissolving box 1, and a stirring member 3 is provided on the rotating shaft 2. The stirring member 3 can be a stirring plate, which is fixed to the rotating shaft 2 through a fixing ring. The number of stirring plates is set according to the internal height of the drug dissolving box 1. The rotating shaft 2 can drive the stirring member 3 to rotate to stir the medicine in the drug dissolving box 1, so that the medicine can be quickly mixed with the water in the drug dissolving box.
[0029] A medicine feeding hopper 5 is provided on the top of the medicine dissolving box 1. By providing the medicine feeding hopper 5, it is convenient to put the medicine into the medicine dissolving box 1. A medicine dispensing mechanism 4 is provided on the upper part of the outer wall of the rotating shaft 2. When the rotating shaft 2 drives the stirring member 3 to rotate, the medicine dispensing mechanism 4 can evenly put the medicine into the medicine dissolving box 1, so that the effect of dissolving the medicine is better.
[0030] A liquid outlet is provided at the bottom of the drug dissolving box 1, and a metering pump 9 connected to the liquid outlet is provided on the outside of the drug dissolving box 1 for accurately controlling the output amount of the evenly mixed medicine in the drug dissolving box 1 to ensure the effect of water quality treatment. A drug blocking component is provided on the outside of the liquid outlet. The drug blocking component can prevent incompletely dissolved medicine particles from entering the liquid outlet, resulting in insufficient medicine concentration in the drug dissolving box 1.
[0031] Specifically, the drug dispensing mechanism 4 includes an annular material trough 41 which is sleeved on the outer wall of the rotating shaft 2. The annular material trough 41 can rotate with the rotation of the rotating shaft 2. The annular material trough 41 is connected to the drug feed hopper 5, and the drug is transported into the annular material trough 41 through the drug feed hopper 5. The outer wall of the annular material trough 41 is connected to a drug outlet pipe 42. The bottom of the annular material trough 41 is inclined toward the drug outlet pipe 42, so that the drug particles entering the annular material trough 41 slide toward the drug outlet pipe 42. As the rotating shaft 2 drives the annular material trough 41 to rotate, the drug particles can be evenly dosed into the drug dissolving box 1 through the drug outlet pipe 42, so that the effect of dissolving the drug is better.
[0032] Specifically, a sealing plate 43 is hingedly connected to the medicine outlet end of the medicine outlet pipe 42 for covering the medicine outlet end of the medicine outlet pipe 42. A first elastic member is connected between the sealing plate 43 and the medicine outlet pipe 42. The first elastic member can be a torsion spring. The first elastic member can continuously provide torque to the sealing plate 43 so that the sealing plate 43 covers the medicine outlet end of the medicine outlet pipe 42 to prevent the medicine particles from sliding out of the medicine outlet pipe 42 under the action of gravity and the bottom of the inclined annular trough 41 when the rotating shaft 2 is not rotating, thereby causing the medicine particles to fall in one place. As the rotating shaft 2 drives the annular trough 41 and then drives the medicine outlet pipe 42 to rotate, the sealing plate 43 opens under the action of centrifugal force, so that the device can only dispense medicine when the rotating shaft 2 rotates.
[0033] Specifically, the drug dispensing mechanism 4 further includes a guide member 45, which is disposed between the annular trough 41 and the rotating shaft 2, so that the annular trough 41 can slide up and down along the rotating shaft 2, and a guide inclined plate 46 is fixedly connected to the inner top wall of the drug dissolving box 1, and the bottom of the guide inclined plate 46 is set as an inclined surface, such as Figure 5 As shown, the bottom surface of the guide inclined plate 46 gradually decreases from left to right, that is, the width of the guide inclined plate gradually increases from left to right.
[0034] The guide member 45 is provided with a push rod 47 slidably connected with the inclined surface. As the rotating shaft 2 rotates, the push rod 47 can be rotated. The shape of the bottom surface of the guide inclined plate 46 coincides with the rotation trajectory of the push rod 47. As the rotating shaft 2 drives the push rod 47 to rotate clockwise, the push rod 47 will drive the annular trough 41 to gradually descend under the guidance of the guide member 45. The outer wall of the rotating shaft 2 is provided with a second elastic member 44 connected with the annular trough 41. The second elastic member 44 is a compression spring, which is sleeved on the rotating shaft 2. As the annular trough 41 descends, the annular trough 41 will compress the second elastic member 44 to store energy. When the push rod 47 rotates After moving to the right edge of the bottom surface of the guide inclined plate 46, as the push rod 47 continues to rotate, the push rod 47 will slip out of the bottom surface of the guide inclined plate 46. Without the support of the push rod 47, the annular trough 41 will rise rapidly under the elastic force of the second elastic member 44 until it hits the limiting ring fixed to the outer wall of the rotating shaft 2 and stops rising. When the annular trough 41 hits the limiting ring, the annular trough 41 will vibrate. The vibration can enable the medicine at the bottom of the annular trough 41 to slide downward better along the inclined surface of the bottom wall of the annular trough 41, thereby preventing the medicine particles in the annular trough 41 from getting damp and adhering to the bottom wall of the annular trough 41.
[0035] Specifically, a roller 48 rotatably connected to the inclined surface is provided at the top of the top rod 47.
[0036] Specifically, the guide member 45 includes a slip ring 451 that is slidably connected to the rotating shaft 2. The slip ring 451 is fixedly connected to the annular trough 41. The inner wall of the slip ring 451 is provided with a slide groove. The outer wall of the rotating shaft 2 is fixedly connected with a slide bar that slides in the slide groove, so that the annular trough 41 can move up and down while rotating with the rotating shaft 2.
[0037] Specifically, the bottom surface of the drug dissolving box 1 is arranged in an arc shape, so as to facilitate the evenly mixed solution to flow into the liquid outlet. The drug blocking component includes an annular edge block 71 fixedly connected to the bottom surface of the drug dissolving box 1. A plurality of annular edge blocks 71 are arranged. The annular edge blocks 71 are arranged around the liquid outlet. The annular edge blocks 71 are gradually lowered along the arc-shaped bottom surface. The cross-section of the annular edge blocks 71 is triangular. When incompletely dissolved drug particles appear, the annular edge blocks 71 can be arranged to block the drug particles that sink to the bottom of the drug dissolving box 1, so as to prevent the incompletely dissolved drug particles from entering the liquid outlet. When the metering pump is working, the drug particles are brought out when the infusion is carried out, resulting in insufficient drug concentration in the drug dissolving box 1.
[0038] Specifically, the bottom of the drug dissolving box 1 is fixedly connected with an arc-shaped cover 72 for covering the liquid outlet through a support rod. The support rod is fixed around the liquid outlet, and the top of the support rod is fixedly connected with an arc-shaped cover 72 for covering the liquid outlet to prevent the drug particles that sink to the bottom of the drug dissolving box 1 from falling into the liquid outlet.
[0039] Specifically, the drug dispensing mechanism 4 includes an annular material trough 41, and a branch pipe is fixedly connected to the bottom of the drug feed hopper 5. The branch pipe passes through the outer wall of the drug dissolving box 1 and is fixedly connected to a drug feed pipe 61. The drug feed pipe 61 is inclined toward the center of the drug dissolving box 1. When drug particles are put into the drug dissolving box 1 through the drug feed hopper 5, the drug particles will first enter the drug feed pipe 61. The end of the drug feed pipe 61 is connected to a drop pipe 62, and under the inclined guidance of the drug feed pipe 61, the drug particles enter the drop pipe 62. The lower end of the drop pipe 62 extends into the annular material trough 41. Through the guidance of the drop pipe 62, the drug particles can better enter the annular material trough 41.
[0040] Working principle:
[0041] When the medicine feeding hopper 5 puts medicine particles into the medicine dissolving box 1 , the medicine particles will enter the drop tube 62 under the inclined guidance of the medicine feeding pipe 61 , and completely enter the annular material trough 41 through the drop tube 62 .
[0042] The medicine particles entering the annular trough 41 enter the medicine outlet pipe 42 under the guidance of the inclined bottom surface of the annular trough 41 .
[0043] When the rotating shaft 2 is not rotating, the sealing plate 43, in cooperation with the first elastic member, blocks the medicine outlet end of the medicine outlet tube 42 to prevent the medicine particles from sliding out of the medicine outlet tube 42 under the action of gravity and the bottom of the inclined annular trough 41 when the rotating shaft 2 is not rotating, thereby causing the medicine particles to fall into one place.
[0044] As the rotating shaft 2 drives the annular material trough 41 and then drives the medicine outlet pipe 42 to rotate, the sealing plate 43 is opened under the action of centrifugal force, so that the medicine particles are evenly fed into the medicine dissolving box 1 through the medicine outlet pipe 42, so that the effect of dissolving the medicine is better.
[0045] As the rotating shaft 2 rotates, the roller 48 at the top of the push rod 47 will be driven to roll along the bottom surface of the guide inclined plate 46. Under the guidance of the bottom surface of the guide inclined plate 46, the push rod 47 will drive the annular trough 41 to move downward. When the roller 48 at the top of the push rod 47 rotates to the right edge of the bottom surface of the guide inclined plate 46, as the push rod 47 continues to rotate, the push rod 47 will escape from the bottom surface of the guide inclined plate 46. Without the support of the push rod 47, the annular trough 41 will rise rapidly under the elastic force of the second elastic member 44 until it hits the limit ring fixed to the outer wall of the rotating shaft 2 and stops rising. When the annular trough 41 hits the limit ring, the annular trough 41 will vibrate. The vibration generated can make the medicine at the bottom of the annular trough 41 slide downward better along the inclined surface of the bottom wall of the annular trough 41, thereby preventing the medicine particles in the annular trough 41 from getting wet and adhering to the bottom wall of the annular trough 41.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
