[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] The adding device of the embodiment of the present invention includes a medicine box 1, an adjustment component 2 and an alarm component 3. The medicine box 1 is provided with a first through hole 11 penetrating the medicine box 1. The adjustment component 2 is arranged in the medicine box 1, and the adjustment component 2 includes a support plate 21 and a sealing cylinder 22. The outer peripheral surface of the support plate 21 is sealedly connected with the inner wall surface of the sealing cylinder 22 to block the bottom of the sealing cylinder 22. The outer peripheral surface of the sealing cylinder 22 is in sliding sealing contact with the inner wall surface of the medicine box 1. The support plate 21 is movably connected to the bottom wall surface of the medicine box 1 so that the support plate 21 and the sealing cylinder 22 can move in the up and down directions relative to the medicine box 1. The sealing cylinder 22 is provided with a liquid outlet 221 penetrating the sealing cylinder 22, and the liquid outlet 221 can be connected with the first through hole 11 to discharge the solution in the medicine box 1. The alarm assembly 3 includes a trigger component 31 and an alarm 32. The trigger component 31 is arranged in the medicine box 1. One end of the trigger component 31 is hinged to the bottom wall of the medicine box 1, and the other end of the trigger component 31 is hinged to the support plate 21. The alarm 32 has a switch 321. The trigger component 31 is used to trigger the switch 321 when the side wall of the medicine box 1 blocks the liquid outlet 221.

[0027] Specifically, Figure 1-Figure 4 As shown, a sealing cylinder 22 with a ring-shaped cross section is fixedly connected to the side wall of the support plate 21, and the sealing cylinder 22 is made of rubber. The outer cylinder wall of the sealing cylinder 22 is sealingly slidably connected to the inner box wall of the medicine box 1, and the axes of the sealing cylinder 22 and the support plate 21 overlap. An alarm 32 is installed on the vertical outer wall of the medicine box 1 near the bottom of the box. The alarm 32 passes through the vertical box wall of the medicine box 1 and extends outward, and the switch 321 of the alarm 32 is located in the medicine box 1.

[0028] The sealing cylinder 22 extends in the up-down direction, and is cylindrical. The support plate 21 is connected to the inner wall surface of the sealing cylinder 22 to block the bottom of the sealing cylinder 22. The upper end of the sealing cylinder 22 is open. The size of the sealing cylinder 22 in the up-down direction is smaller than the size of the medicine box 1 in the up-down direction. The connection between the support plate 21 and the sealing cylinder 22 enables the support plate 21 to move up and down relative to the medicine box 1 when the support plate 21 moves up and down. The liquid outlet 221 is provided on the sealing cylinder 22 and arranged adjacent to the support plate 21, and the liquid outlet 221 is located above the support plate 21. When the support plate 21 and the sealing cylinder 22 move downward, the liquid outlet 221 can be connected to the first through hole 11 to discharge the liquid in the sealing cylinder 22.

[0029] For example, there are multiple liquid outlet holes 221, and the multiple liquid outlet holes 221 are arranged at intervals in the circumferential direction of the sealing tube 22. When there are two liquid outlet holes 221, the two liquid outlet holes 221 are symmetrically arranged on the side wall surface of the sealing tube 22 in the left-right direction.

[0030] There are multiple alarms 32, and the multiple alarms 32 are arranged at intervals in the circumferential direction of the sealing tube 22. When there are two alarms 32, the two alarms 32 are symmetrically arranged on the side wall surface of the sealing tube 22 in the left-right direction, the openings of the two alarms 32 are set back to back, and the switches 321 of the two alarms 32 are both located in the medicine box 1, and the diffusion end of the alarm 32 faces outside the medicine box 1.

[0031] When the mixed flocculant is added through the medicine box 1, the support plate 21 and the sealing cylinder 22 move downward under the action of gravity of the flocculant solution, so that the liquid outlet 221 is connected to the first through hole 11 to discharge the flocculant solution. When the amount of liquid in the medicine box 1 decreases and the pressure of the liquid in the medicine box 1 on the support plate 21 decreases, the support plate 21 and the sealing cylinder 22 are adjusted to move upward so that the inner wall surface of the medicine box 1 blocks the liquid outlet 221. At the same time, the switch 321 of the alarm 32 is triggered by the trigger component 31, and the alarm 32 emits an alarm sound to remind the user to add flocculant solution to the medicine box 1.

[0032] In this embodiment, a support plate 21 and a sealing cylinder 22 are arranged in the medicine box 1 so as to be movable up and down relative to the medicine box 1. The gravity of the flocculant solution is used to control the support plate 21 and the sealing cylinder 22 to move downward, so that the liquid outlet 221 is connected to the first through hole 11 to discharge the flocculant solution in the medicine box 1. When the flocculant solution is reduced to a preset value, the support plate 21 and the sealing cylinder 22 are controlled to move upward, so that the inner wall surface of the medicine box 1 blocks the liquid outlet 221 and the alarm 32 is triggered by the trigger component 31 to sound an alarm. The flocculant solution in the medicine box 1 flows out evenly through the liquid outlet 221 and the first through hole 11, thereby ensuring the flocculation effect.

[0033] Furthermore, in this embodiment, by associating the amount of flocculant solution in the medicine box 1 with the alarm 32, an alarm is automatically triggered when the amount of flocculant solution is lower than a preset value, thereby promptly reminding the staff to add flocculant solution to the medicine box 1, thereby avoiding the phenomenon of poor flocculation effect caused by untimely addition of flocculant, and ensuring the flocculation effect.

[0034] Compared with the method of directly pouring the flocculant solution in the reagent box 1 into the flocculation tank, in this embodiment, the flocculant solution is slowly and gradually discharged by opening the liquid outlet 221 on the sealing cylinder 22 and the first through hole 11 on the reagent box 1, which can improve the flocculation effect.

[0035] In some embodiments, the trigger component 31 includes a slider 311, a connecting rod 312 and a push rod 313. A slide groove 12 cooperating with the slider 311 is opened on the bottom wall surface of the medicine box 1. The slider 311 can be slidably installed in the slide groove 12. One end of the connecting rod 312 is hinged to the slider 311, and the other end of the connecting rod 312 is hinged to the support plate 21. The up and down movement of the support plate 21 can drive the slider 311 to approach and move away from the alarm 32. The push rod 313 is arranged at the end of the slider 311 facing the alarm 32 and can abut against the switch 321.

[0036] Specifically, Figure 1-Figure 3 As shown, a slide groove 12 corresponding to the alarm 32 is symmetrically opened on the inner wall surface of the medicine box 1, and the slide groove 12 is a T-shaped slide groove 12, which extends in the left and right directions. A T-shaped slider 311 is slidably connected in the T-shaped slide groove 12, and the upper end of the T-shaped slider 311 passes through the upper end notch of the T-shaped slide groove 12 and extends upward. The lower end of the connecting rod 312 is hinged to the upper end of the slider 311, and the upper end of the connecting rod 312 is hinged to the support plate 21, and the hinge between the connecting rod 312 and the support plate 21 is arranged close to the central axis direction of the sealing tube 22, and a push rod 313 is provided at the left end of the slider 311 on the left, and a push rod 313 is provided at the right end of the slider 311 on the right.

[0037] When the support plate 21 is in the upward direction, the supporting plate 21 drives the connecting rod 312 to drive the sliding block 311 to move upward. The hinge point of the connecting rod 312 and the sliding block 311 is located on the left side of the hinge point of the connecting rod 312 and the supporting plate 21. Since the sliding block 311 is slidably fixed in the sliding block 12, the sliding block 311 cannot move upward, causing the sliding block 311 to move right in the sliding block 12. That is to say, the angle between the connecting rod 312 and the up and down direction gradually decreases until the connecting rod 312 becomes vertical. At this time, the hinge point of the connecting rod 312 and the sliding block 311 and the hinge point of the connecting rod 312 and the supporting plate 21 are in the same position in the up and down direction. Since the sliding block 311 slides to the right side of the sliding block 12, the abutment rod 313 set at the right end of the sliding block 311 abuts against the switch 321 of the alarm 32, and the alarm 32 is turned on to alarm.

[0038] It is understandable that the flocculant solution needs to be added slowly to the flocculation tank, and the adding process requires human monitoring. It is difficult to detect when the reagent box 1 is empty. Since the capacity of the reagent box 1 is limited, the flocculant solution needs to be added to the reagent box 1 multiple times. The adding time is difficult to grasp, and people are required to monitor the situation of the flocculant solution in the reagent box 1. If it is added too early, the volume of the flocculant solution added to the reagent box 1 is small, and the time interval is shortened. If it is added too late, the adding process to the flocculation tank is interrupted, affecting the flocculation effect. In this embodiment, the up and down movement of the support plate 21 is converted into the left and right movement of the slider 311 through the setting of the trigger component 31, and the slider 311 is driven to move to the left when the support plate 21 moves downward, and the slider 311 is driven to move to the right when the support plate 21 moves upward so that the abutment rod 313 abuts against the switch 321 of the alarm 32, reminding the staff that the flocculant solution has been used up and needs to be added. The staff does not need to pay attention to the situation of the flocculant solution in the medicine box 1 frequently, and will be reminded to add the medicine solution after the flocculant solution is used up, thus saving manpower.

[0039] In some embodiments, the trigger component 31 also includes a ball 314, and a ball groove 3111 is opened on the end surface of the slider 311 away from the connecting rod 312. One end of the ball 314 is engaged in the ball groove 3111, and the other end of the ball 314 is rollingly connected to the slide groove 12.

[0040] Specifically, Figure 3 As shown, a ball groove 3111 is opened at one end of the T-shaped slider 311 close to the bottom of the T-shaped slide groove 12, and a ball 314 is rollingly connected in the ball groove 3111. The end of the ball 314 away from the bottom of the ball groove 3111 passes through the notch of the ball groove 3111 and extends outward, and is rollingly connected to the bottom of the T-shaped slide groove 12. The ball groove 3111 is closed, and the diameter of the ball 314 is larger than the diameter of the notch of the ball groove 3111, so that the T-shaped slider 311 can move faster.

[0041] In some embodiments, there are multiple alarm components 3 , and the multiple alarm components 3 are arranged at intervals in the circumferential direction of the medicine box 1 .

[0042] Specifically, the provision of multiple alarm components 3 can simultaneously sound an alarm at multiple circumferential positions of the medicine box 1, so that staff members located at different positions of the medicine box 1 can hear the alarm sound. This also prevents damage to the alarm 32 that would affect the alarm, thereby improving the reliability of the alarm component 3.

[0043] In some embodiments, the adding device also includes a telescopic component 4, which includes a spring 41, a sliding rod 42 and a limit block 43. A sliding hole 13 that passes through the bottom wall of the medicine box 1 is opened. One end of the sliding rod 42 passes through the sliding hole 13 and extends into the medicine box 1 and is connected to the support plate 21. The other end of the sliding rod 42 is connected to the limit piece. The spring 41 is located in the medicine box 1 and is mounted on the sliding rod 42.

[0044] Specifically, Figure 1 As shown, there are multiple telescopic components 4, and the multiple telescopic components 4 are arranged at intervals in the circumferential direction of the medicine box 1, and the multiple telescopic components 4 are all located between two T-shaped slide grooves 12. Multiple springs 41 are evenly and equidistantly distributed in an annular shape on the bottom wall of the medicine box 1, and the upper ends of the multiple springs 41 are commonly fixedly connected to the support plate 21. A sliding hole 13 is opened on the bottom of the medicine box 1 located in the spring 41, and a sliding rod 42 is slidably connected in the sliding hole 13. The upper end of the sliding rod 42 is fixedly connected to the support plate 21, and the lower end of the sliding rod 42 is fixedly connected to the limiting block 43 to limit the support plate 21.

[0045] In some embodiments, the telescopic assembly 4 also includes a support rod 44, which is arranged between the spring 41 and the connecting rod 312, one end of the support rod 44 is connected to the support plate 21, and the other end of the support rod 44 can abut against the bottom wall surface of the medicine box 1 to support the support plate 21.

[0046] Specifically, Figure 1 As shown, the inner box bottom of the medicine box 1 between the spring 41 and the T-shaped slide groove 12 is symmetrically fixedly connected with a support rod 44, and the upper end of the support rod 44 is against the support plate 21 to support the support plate 21. When the support plate 21 moves upward, it drives the support rod 44 to move upward synchronously and separate from the bottom wall of the medicine box 1.

[0047] During the use of the medicine box 1, the flocculant solution in the medicine box 1 pushes the support plate 21 downward under the action of gravity to compress the spring 41 until the liquid outlet 221 is connected with the first through hole 11. Due to the support of the support rod 44, the support plate 21 cannot continue to move downward, and the flocculant solution flows out through the liquid outlet 221 and the first through hole 11. When the amount of flocculant solution in the medicine box 1 decreases, the pressure of the flocculant solution in the medicine box 1 on the support plate 21 decreases, and the spring 41 gradually resets, exerting an upward thrust on the support plate 21, and the support plate 21 and the sealing cylinder 22 both move upward. At this time, the liquid outlet 221 is separated from the first through hole 11, and the side wall surface of the medicine box 1 blocks the liquid outlet 221, and the flocculant solution cannot flow out. The support plate 21 applies a force to the T-shaped slider 311 through the connecting rod 312, and then the T-shaped slider 311 moves in the direction of the alarm 32, and the abutment rod 313 abuts against the switch 321 of the alarm 32, and the alarm 32 makes a sound to remind the staff that the medicine has been used up and needs to be added. The staff does not need to pay attention to the situation of the medicine in the medicine box 1 frequently, and can be reminded to add medicine after the medicine has been used up, saving manpower.

[0048] In some embodiments, the adding device also includes a spare box 5, which is connected to the side wall of the medicine box 1. A connecting hole 51 is provided at one end of the spare box 5 close to the medicine box 1. A second through hole 14 that penetrates the medicine box 1 is provided on the medicine box 1. The second through hole 14 is connected to the connecting hole 51. The spare box 5 is used to add solution to the medicine box 1.

[0049] Specifically, Figure 1 As shown, a standby box 5 with an upper opening is symmetrically fixedly installed on the vertical outer box wall of the medicine box 1 just above the liquid outlet pipe 6, and a connecting hole 51 is opened on the vertical box wall of the standby box 5 close to the medicine box 1, and the connecting hole 51 is arranged close to the bottom of the standby box 5, and the connecting hole 51 is connected to the second through hole 14 to add the flocculant solution in the standby box 5 into the medicine box 1.

[0050] In this embodiment, by setting the spare box 5, after the medicine box 1 sends out an alarm, liquid still flows into the medicine box 1, and then the support plate 21 moves downward until the liquid outlet 221 is connected with the first through hole 11, reminding the staff to add liquid medicine while the medicine box 1 can still continue to flow out of the medicine, which does not affect the addition of liquid medicine in the production process and reserves time for the staff to add liquid medicine.

[0051] In some embodiments, the sealing cylinder 22 is provided with a liquid inlet hole 222 that penetrates the sealing cylinder 22. The liquid inlet hole 222 and the liquid outlet hole 221 are arranged at intervals in the extension direction of the sealing cylinder 22, and the liquid inlet hole 222 is closer to the second through hole 14 than the liquid outlet hole 221. When the sealing cylinder 22 moves upward, the liquid inlet hole 222 can be connected with the second through hole 14.

[0052] Specifically, Figure 1-Figure 3 As shown, the sealing cylinder 22 is provided with a liquid inlet hole 222 and a liquid outlet hole 221, and the liquid inlet hole 222 is located above the liquid outlet hole 221. When the support plate 21 and the sealing cylinder 22 move upward, the liquid inlet hole 222 on the sealing cylinder 22 can be connected with the second through hole 14 and the connecting hole 51 to transfer the standby solution in the standby box 5 to the medicine box 1. Under the action of the standby solution, the support plate 21 and the sealing cylinder 22 move downward again and are connected with the first through hole 11, ensuring that the flocculant solution is still discharged outward after the medicine box 1 sends out an alarm, thereby ensuring the flocculation effect.

[0053] In some embodiments, the sealing tube 22 has a liquid outlet state and a liquid inlet state. In the liquid outlet state, the liquid outlet hole 221 is connected to the first through hole 11 , and in the liquid inlet state, the liquid inlet hole 222 is connected to the second through hole 14 .

[0054] Specifically, when the sealing cylinder 22 moves downward, the liquid outlet hole 221 is connected with the first through hole 11 to realize liquid discharge; when the sealing cylinder 22 moves upward, the liquid outlet hole 221 is separated from the first through hole 11, and the liquid inlet hole 222 is connected with the second through hole 14. Since the second through hole 14 is connected with the connecting hole 51, the standby box 5 can pass the standby solution into the medicine box 1, ensuring that the adding device still has flocculant solution added to the flocculation tank after the alarm, thereby ensuring the flocculation effect.

[0055] In some embodiments, an extending direction of the inner wall surface of the communicating hole 51 and an extending direction of the supporting plate 21 form an included angle.

[0056] Specifically, the liquid inlet hole 222 is located above the liquid outlet hole 221 , and the hole walls of the liquid inlet hole 222 and the connecting hole 51 are both inclined and arranged close to the bottom of the medicine box 1 , so as to facilitate the transportation of the standby solution in the standby box 5 to the medicine box 1 .

[0057] In some embodiments, an extending direction of the inner wall surface of the second through hole 14 and an extending direction of the support plate 21 form an included angle.

[0058] For the convenience of description, the second through hole 14 on the right is taken as an example. The left end of the hole wall of the second through hole 14 is lower than the right end. At the same time, the left end of the hole wall of the connecting hole 51 is lower than the right end, which facilitates the transportation of the reserve solution in the reserve box 5 on the right to the medicine box 1.

[0059] In some embodiments, an extending direction of the inner wall surface of the first through hole 11 and an extending direction of the support plate 21 form an included angle.

[0060] For ease of description, the first through hole 11 on the right is taken as an example. The left end of the hole wall of the first through hole 11 is higher than the right end, so that the flocculant solution in the medicine box 1 can be discharged through the first through hole 11.

[0061] In some embodiments, the adding device further includes a liquid outlet pipe 6 , one end of which is connected to the medicine box 1 , and the liquid outlet pipe 6 is in communication with the first through hole 11 .

[0062] One end of the liquid outlet pipe 6 is connected to the first through hole 11, and the liquid outlet pipe 6 and the hole wall of the first through hole 11 have the same inclination direction, which is convenient for the discharge of the flocculant solution.

[0063] When the flocculant solution in the medicine box 1 is insufficient, the spring 41 pushes the support plate 21 and the sealing tube 22 to move upward, and the alarm 32 is triggered to remind the staff to add liquid medicine. The liquid outlet 221 and the liquid outlet pipe 6 are separated. At this time, the axis of the liquid inlet hole 222 and the connecting hole 51 overlap, which is convenient for liquid to enter the medicine box 1.

[0064] In some embodiments, the adding device further comprises an indicator rod 7 , one end of which extends into the medicine box 1 and is connected to the support plate 21 .

[0065] Specifically, Figure 1 As shown, an indicator rod 7 is fixedly connected to the center of the top side wall of the support plate 21 to facilitate observation of the liquid level of the medicine in the medicine box 1.

[0066] For example, the materials of the medicine box 1 and the spare box 5 are both stainless steel, which increases the life of the medicine box 1 and the spare box 5.

[0067] For example, the flocculant is a PAC flocculant.

[0068] When a certain amount of mixed PAC flocculant is added to the medicine box 1, the support plate 21 moves downward under the action of gravity until the liquid outlet hole 221 overlaps the axis of the liquid outlet pipe 6. Under the support of the support rod 44, the support plate 21 cannot continue to move downward. The PAC flocculant flows out through the liquid outlet hole 221 and the liquid outlet pipe 6. When the amount of liquid in the medicine box 1 decreases, the pressure of the liquid in the medicine box 1 on the support plate 21 decreases, and the spring 41 gradually resets, exerting an upward thrust on the support plate 21. The support plate 21 and the sealing cylinder 22 both move upward. At this time, the liquid outlet hole 221 is separated from the liquid outlet pipe 6 and the liquid cannot flow out. The support plate 21 applies a force to the T-shaped slider 311 through the connecting rod 312, and then the T-shaped slider 311 moves in the direction of the alarm 32, and the abutment rod 313 abuts against the switch 321 of the alarm 32, and the alarm 32 makes a sound to remind the staff that the medicine has been used up and needs to be added. The staff does not need to pay attention to the situation of the medicine in the medicine box 1 frequently, and can be reminded to add medicine after the medicine has been used up, saving manpower.

[0069] When there is insufficient PAC flocculant in the medicine box 1, the spring 41 pushes the support plate 21 and the sealing tube 22 to move upward, and the alarm 32 is triggered to remind the staff to add liquid medicine. The liquid outlet 221 and the liquid outlet pipe 6 are separated. At this time, the axis of the liquid inlet 222 and the connecting hole 51 overlap, and the liquid medicine in the spare box 5 is injected into the medicine box 1, so that liquid still flows into the medicine box 1, and then the support plate 21 moves downward until the axis of the liquid outlet hole 221 and the liquid outlet pipe 6 overlap; while reminding the staff to add liquid medicine, the medicine box 1 can still continue to flow out of the medicine, which does not affect the addition of liquid medicine in the production process and reserves time for the staff to add liquid medicine.
