Description

Technical Field

[0001] This invention relates to the field of liquid addition technology, and more specifically to an addition device. Background Technology

[0002] During coal mining, groundwater comes into contact with coal seams and rock strata, resulting in a much higher suspended solids content in groundwater compared to surface water. Furthermore, the suspended solids in groundwater are small in size and have a low specific gravity, necessitating the addition of flocculants to remove them. Polyaluminum chloride (PAC) is commonly used as a flocculant. However, PAC is a solid flocculant, requiring it to be mixed with water in a reagent tank to form a flocculation solution before being added to the flocculation tank. This inconsistent addition rate hinders effective flocculation. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide an additive device that can control the additive rate to ensure flocculation effect.

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

[0026] The adding device of this invention includes a medicine tank 1, an adjusting component 2, and an alarm component 3. The medicine tank 1 has a first through hole 11 penetrating the medicine tank 1. The adjusting component 2 is disposed inside the medicine tank 1 and includes a support plate 21 and a sealing cylinder 22. The outer peripheral surface of the support plate 21 is sealed to 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 tank 1. The support plate 21 is movably connected to the bottom wall surface of the medicine tank 1 so that the support plate 21 and the sealing cylinder 22 can move vertically relative to the medicine tank 1. The sealing cylinder 22 has a liquid outlet 221 penetrating the sealing cylinder 22, which communicates with the first through hole 11 to discharge the solution inside the medicine tank 1. The alarm assembly 3 includes a triggering component 31 and an alarm 32. The triggering component 31 is located inside the medicine tank 1. One end of the triggering component 31 is hinged to the bottom wall of the medicine tank 1, and the other end of the triggering component 31 is hinged to the support plate 21. The alarm 32 has a switch 321. The triggering component 31 is used to activate the switch 321 when the liquid outlet hole 221 is blocked on the side wall of the medicine tank 1.

[0027] Specifically, such as Figures 1-4 As shown, a sealing cylinder 22 with an annular cross-section is fixedly connected to the side wall of the support plate 21. The sealing cylinder 22 is made of rubber, and its outer wall is slidably connected to the inner wall of the medicine box 1. 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. The alarm 32 passes through the vertical wall of the medicine box 1 and extends outward. The switch 321 of the alarm 32 is located inside the medicine box 1.

[0028] The sealing cylinder 22 extends vertically and is cylindrical. The support plate 21 is connected to the inner wall of the sealing cylinder 22 to seal the bottom of the sealing cylinder 22. The upper end of the sealing cylinder 22 is open. The vertical dimension of the sealing cylinder 22 is smaller than that of the medicine tank 1. The connection between the support plate 21 and the sealing cylinder 22 allows the sealing cylinder 22 to move vertically relative to the medicine tank 1 when the support plate 21 moves vertically. 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 communicate with the first through hole 11 to discharge the liquid in the sealing cylinder 22.

[0029] For example, there are multiple liquid outlet holes 221, which are arranged at intervals in the circumferential direction of the sealing cylinder 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 cylinder 22 in the left-right direction.

[0030] There are multiple alarms 32, which are arranged at intervals around the circumference of the sealed cylinder 22. When there are two alarms 32, the two alarms 32 are symmetrically arranged on the side wall of the sealed cylinder 22 in the left-right direction. The openings of the two alarms 32 are set opposite to each other, and the switches 321 of the two alarms 32 are both located inside the medicine box 1. The diffuser end of the alarm 32 faces outward from the medicine box 1.

[0031] When the mixed flocculant is added through the reagent tank 1, the support plate 21 and the sealing cylinder 22 move downward under the gravity of the flocculant solution, so that the outlet hole 221 is connected to the first through hole 11 to discharge the flocculant solution. When the amount of solution in the reagent tank 1 decreases and the pressure of the solution 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 of the reagent tank 1 blocks the outlet hole 221. At the same time, the switch 321 of the alarm 32 is triggered by the triggering component 31, and the alarm 32 sounds an alarm to remind that flocculant solution needs to be added to the reagent tank 1.

[0032] In this embodiment, a support plate 21 and a sealing cylinder 22 that can move up and down relative to the reagent tank 1 are provided inside the reagent tank 1. The gravity of the flocculant solution controls the support plate 21 and the sealing cylinder 22 to move downward, so that the liquid outlet 221 communicates with the first through hole 11 to discharge the flocculant solution in the reagent tank 1. When the flocculant solution decreases to a preset value, the support plate 21 and the sealing cylinder 22 are controlled to move upward, so that the inner wall of the reagent tank 1 blocks the liquid outlet 221. At the same time, the alarm 32 is triggered by the triggering component 31 to sound an alarm. The flocculant solution in the reagent tank 1 flows out evenly through the liquid outlet 221 and the first through hole 11 to ensure the flocculation effect.

[0033] Furthermore, in this embodiment, the amount of flocculant solution in the reagent tank 1 is associated with the alarm 32. When the amount of flocculant solution is lower than a preset value, the alarm is automatically triggered to promptly remind the staff to add flocculant solution to the reagent tank 1, thereby avoiding the phenomenon of poor flocculation effect caused by untimely addition of flocculant and ensuring the flocculation effect.

[0034] Compared to directly pouring the flocculant solution from the reagent tank 1 into the flocculation tank, this embodiment improves the flocculation effect by slowly and gradually discharging the flocculant solution through an outlet hole 221 on the sealing cylinder 22 and a first through hole 11 on the reagent tank 1.

[0035] In some embodiments, the triggering component 31 includes a slider 311, a connecting rod 312, and a stop rod 313. A groove 12 that cooperates with the slider 311 is provided on the bottom wall of the medicine box 1. The slider 311 is slidably installed in the 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 move closer to and away from the alarm 32. The stop rod 313 is provided at the end of the slider 311 facing the alarm 32 and can abut against the switch 321.

[0036] Specifically, such as Figures 1-3 As shown, the inner wall of the medicine box 1 is symmetrically provided with slide grooves 12 corresponding to the alarm 32. The slide grooves 12 are T-shaped slide grooves 12, which extend in the left and right direction. A T-shaped slider 311 is slidably connected in the T-shaped slide groove 12. The upper end of the T-shaped slider 311 passes through the upper end slot 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. The upper end of the connecting rod 312 is hinged to the support plate 21. The hinge point of the connecting rod 312 and the support plate 21 is arranged close to the central axis of the sealing cylinder 22. The left end of the slider 311 on the left side is provided with a stop rod 313, and the right end of the slider 311 on the right side is provided with a stop rod 313.

[0037] For ease of description, we will take the slider 311 and the slide groove 12 located on the right as an example. When the support plate 21 moves upward, the support plate 21 drives the connecting rod 312 to move the slider 311 upward. The hinge of the connecting rod 312 and the slider 311 is located to the left of the hinge of the connecting rod 312 and the support plate 21. Since the slider 311 is slidably fixed in the slide groove 12, the slider 311 cannot move upward, causing the slider 311 to move to the right in the slide groove 12. That is to say, the angle between the connecting rod 312 and the vertical direction gradually decreases until the connecting rod 312 becomes vertical. At this time, the hinge of the connecting rod 312 and the slider 311 is at the same position in the vertical direction as the hinge of the connecting rod 312 and the support plate 21. Since the slider 311 slides to the right side of the slide groove 12, the abutment 313 set at the right end of the slider 311 abuts against the switch 321 of the alarm 32, and the alarm 32 is turned on to sound an alarm.

[0038] Understandably, the flocculant solution needs to be added to the flocculation tank slowly, requiring manual monitoring during the addition process. It is difficult to notice when the reagent tank 1 is empty. Due to the limited capacity of reagent tank 1, the flocculant solution needs to be added to reagent tank 1 multiple times. The timing of the addition is difficult to control, requiring someone to monitor the status of the flocculant solution in reagent tank 1. If it is added too early, the amount of flocculant solution added to reagent tank 1 will be less, and the time interval will be shortened. If it is added too late, the addition process to the flocculation tank will be 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 by the setting of the trigger component 31. When the support plate 21 moves downward, it drives the slider 311 to move to the left, and when the support plate 21 moves upward, it drives the slider 311 to move to the right so that the stop 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 flocculant solution in the reagent tank 1 frequently. The staff is reminded to add the solution after the flocculant solution has been used up, saving manpower.

[0039] In some embodiments, the triggering component 31 further includes a ball 314. A ball groove 3111 is provided on the end face of the slider 311 away from the connecting rod 312. One end of the ball 314 is fitted in the ball groove 3111, and the other end of the ball 314 is tactilely connected to the slide groove 12.

[0040] Specifically, such as Figure 3 As shown, a ball groove 311 is provided at one end of the T-shaped slider 311 near the bottom of the T-shaped groove 12. A ball 314 is rolled in the ball groove 3111. The end of the ball 314 away from the bottom of the ball groove 3111 passes through the opening of the ball groove 3111 and extends outward, and is rolled in connection with the bottom of the T-shaped groove 12. The ball groove 3111 is narrowed. The diameter of the ball 314 is larger than the diameter of the opening of the ball groove 3111, which makes the T-shaped slider 311 move faster.

[0041] In some embodiments, there are multiple alarm components 3, which are arranged at intervals around the circumference of the medicine box 1.

[0042] Specifically, the setting of multiple alarm components 3 can simultaneously issue alarms at multiple locations around the medicine box 1, making it convenient for staff located in different positions of the medicine box 1 to hear the alarm sound, while also preventing damage to the alarm device 32 from affecting the alarm and improving the reliability of the alarm components 3.

[0043] In some embodiments, the adding device further includes a telescopic component 4, which includes a spring 41, a slide rod 42, and a limiting block 43. A sliding hole 13 penetrating the bottom wall surface is provided on the bottom wall surface of the medicine box 1. One end of the slide rod 42 passes through the sliding hole 13 and extends into the medicine box 1 to be connected to the support plate 21. The other end of the slide rod 42 is connected to the limiting component. The spring 41 is located inside the medicine box 1 and is sleeved on the slide rod 42.

[0044] Specifically, such as Figure 1 As shown, there are multiple telescopic components 4, which are spaced apart around the circumference of the medicine box 1. All of the telescopic components 4 are located between two T-shaped sliding grooves 12. Multiple fixedly connected springs 41 are evenly distributed in a ring on the bottom wall of the medicine box 1. The upper ends of the multiple springs 41 are all fixedly connected to a support plate 21. A sliding hole 13 is provided on the bottom of the medicine box 1 within the springs 41. A sliding rod 42 is slidably connected within 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 a limit block 43 to limit the movement of the support plate 21.

[0045] In some embodiments, the telescopic assembly 4 further includes a support rod 44, which is disposed 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 of the medicine box 1 to support the support plate 21.

[0046] Specifically, such as Figure 1 As shown, a support rod 44 is symmetrically fixedly connected to the bottom of the medicine box 1 between the spring 41 and the T-shaped slide 12. The upper end of the support rod 44 abuts 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 reagent tank 1, the flocculant solution inside the reagent tank 1 pushes the support plate 21 downward under the action of gravity, compressing the spring 41 until the outlet hole 221 connects with the first through hole 11. Due to the support of the support rod 44, the support plate 21 can no longer move downward, and the flocculant solution flows out through the outlet hole 221 and the first through hole 11. When the amount of flocculant solution in the reagent tank 1 decreases, the pressure of the flocculant solution on the support plate 21 decreases, the spring 41 gradually returns to its original position, and applies an upward thrust to the support plate 21. Both the support plate 21 and the sealing cylinder 22 move upward. At this time, the outlet hole 221 separates from the first through hole 11, and the side wall of the reagent tank 1 blocks the outlet hole 221, preventing the flocculant solution from flowing out. The support plate 21 applies a force to the T-shaped slider 311 via the connecting rod 312, causing the T-shaped slider 311 to move towards the alarm 32. The stop rod 313 abuts against the switch 321 of the alarm 32, and the alarm 32 sounds to remind the staff that the medicine has been used up and needs to be refilled. This eliminates the need for staff to frequently check the medicine tank 1 for the medicine, as the staff is reminded to refill the medicine after it has been used up, thus saving manpower.

[0048] In some embodiments, the adding device further includes a spare tank 5, which is connected to the side wall of the medicine tank 1. A connecting hole 51 is provided at one end of the spare tank 5 near the medicine tank 1. A second through hole 14 is provided on the medicine tank 1, which communicates with the connecting hole 51. The spare tank 5 is used to add solution into the medicine tank 1.

[0049] Specifically, such as Figure 1 As shown, a spare box 5 with an opening at the top is symmetrically fixed on the vertical outer wall of the reagent box 1 located directly above the liquid outlet pipe 6. A connecting hole 51 is opened on the vertical wall of the spare box 5 near the reagent box 1, and the connecting hole 51 is located near the bottom of the spare box 5. The connecting hole 51 is connected to the second through hole 14 to add the flocculant solution in the spare box 5 into the reagent box 1.

[0050] In this embodiment, the setting of the spare box 5 ensures that after the medicine box 1 issues an alarm, liquid continues to flow into the medicine box 1, and the support plate 21 moves downward until the liquid outlet 221 and the first through hole 11 are connected. This reminds the staff to add medicine while the medicine box 1 can continue to flow outward, without affecting the addition of medicine in the production process, and at the same time, it allows the staff time to add 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 extending 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 communicate with the second through hole 14.

[0052] Specifically, such as Figures 1-3 As shown, the sealing cylinder 22 is provided with an inlet hole 222 and an outlet hole 221, and the inlet hole 222 is located above the outlet hole 221. When the support plate 21 and the sealing cylinder 22 move upward, the inlet hole 222 on the sealing cylinder 22 can communicate with the second through hole 14 and the connecting hole 51 to transfer the spare solution in the spare tank 5 to the reagent tank 1. Under the action of the spare solution, the support plate 21 and the sealing cylinder 22 move downward again and communicate with the first through hole 11 to ensure that the flocculant solution is still discharged after the reagent tank 1 issues an alarm, thus ensuring the flocculation effect.

[0053] In some embodiments, the sealing cylinder 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 221 connects with the first through hole 11 to allow liquid to be discharged. When the sealing cylinder 22 moves upward, the liquid outlet 221 separates from the first through hole 11, and the liquid inlet 222 connects with the second through hole 14. Since the second through hole 14 connects with the connecting hole 51, the spare solution is introduced into the reagent tank 1 from the spare tank 5, ensuring that the flocculant solution is still added to the flocculation tank after the alarm is triggered, thus ensuring the flocculation effect.

[0055] In some embodiments, there is an angle between the extending direction of the inner wall surface of the connecting hole 51 and the extending direction of the support plate 21.

[0056] Specifically, the inlet hole 222 is located above the outlet hole 221. The walls of both the inlet hole 222 and the connecting hole 51 are inclined close to the bottom of the medicine tank 1, which facilitates the transfer of the spare solution in the spare tank 5 to the medicine tank 1.

[0057] In some embodiments, the extension direction of the inner wall surface of the second through hole 14 has an angle with the extension direction of the support plate 21.

[0058] For ease of description, the second through hole 14 on the right side will be used 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 transfer of the spare solution in the spare box 5 on the right side to the medicine box 1.

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

[0060] For ease of description, we will take the first through hole 11 on the right side as an example. The left end of the hole wall of the first through hole 11 is higher than the right end, which makes it easier for the flocculant solution in the reagent tank 1 to 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 tank 1, and the liquid outlet pipe 6 is connected to the first through hole 11.

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

[0063] When the flocculant solution in the reagent tank 1 is insufficient, the spring 41 pushes the support plate 21 and the sealing cylinder 22 to move upward, and the alarm 32 is triggered to remind the staff to add the solution. The liquid outlet 221 and the liquid outlet pipe 6 are separated. At this time, the inlet hole 222 and the connecting hole 51 are aligned, which facilitates the liquid to be added into the reagent tank 1.

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

[0065] Specifically, such as 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 tank 1.

[0066] For example, both medicine box 1 and spare box 5 are made of stainless steel, which improves their lifespan.

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

[0068] A certain amount of mixed PAC flocculant is added to the reagent tank 1. Under the action of gravity, the support plate 21 moves downward until the outlet hole 221 overlaps with the axis of the outlet pipe 6. With the support of the support rod 44, the support plate 21 can no longer move downward. The PAC flocculant flows out through the outlet hole 221 and the outlet pipe 6. When the amount of liquid in the reagent tank 1 decreases, the pressure of the liquid in the reagent tank 1 on the support plate 21 decreases, the spring 41 gradually returns to its original position, and applies an upward thrust to the support plate 21. Both the support plate 21 and the sealing cylinder 22 move upward. At this time, the outlet hole 221 is separated from the outlet pipe 6 and the liquid can no longer flow out. The support plate 21 applies a force to the T-shaped slider 311 via the connecting rod 312, causing the T-shaped slider 311 to move towards the alarm 32. The stop rod 313 abuts against the switch 321 of the alarm 32, and the alarm 32 sounds to remind the staff that the medicine has been used up and needs to be refilled. This eliminates the need for staff to frequently check the medicine tank 1 for the medicine, as the staff is reminded to refill the medicine after it has been used up, thus saving manpower.

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