DETAILED DESCRIPTION

[0032] As shown in Figures 1-10 Fig. 1, the refilling type scale inhibition tank comprises a tank body 1 and scale inhibitors filled in the tank body 1. In actual use, the scale inhibitors can be materials such as silicon phosphorus crystals, and refer to Figure 1 Fig. 1. The water inlet pipe 103 is connected to the outer wall of the tank body 1 at a lower position, and the water outlet pipe 101 is connected to the outer wall of the tank body 1 at an upper position. The filter screen is installed in the water inlet pipe 103 and the water outlet pipe 101 to prevent the scale inhibitors from being led out through the water inlet pipe 103 or the water outlet pipe 101. In use, water flows from bottom to top and passes through the scale inhibitors. The scale inhibitors can react with cations (such as calcium and magnesium) in water to release a disturbing medium, inhibit the formation of scale crystal nucleus, and make the water outlet of the equipment generate no scale after being heated.

[0033] Specifically, in order to avoid that the water flow directly washes the scale inhibitors after entering the tank body 1, the filter screen 4 is fixedly arranged inside the tank body 1 at a position above the water inlet pipe 103. The pore size of the filter screen 4 is smaller than the volume of the scale inhibitors, and refer to Figure 2 Fig. 1. At this time, the water entering the tank body 1 through the water inlet pipe 103 will first fill the bottom end position of the tank body 1, and then slowly rise, thereby being beneficial to avoiding that the water flow washes the scale inhibitors and causes them to break.

[0034] In specific applications, the temperature and flow rate of the water flow can cause the descaling agent to be consumed at different rates. In order to replenish the descaling agent in the tank 1 in a timely manner, a feeding tank 2 is arranged at the top end of the tank 1. As shown in Figures 1-3 , the bottom end of the feeding tank 2 is fixedly provided with a square tube 201, and the square tube 201 is in communication with the feeding tank 2. The end of the square tube 201 away from the feeding tank 2 penetrates the tank 1 downward and is fixedly connected with the tank 1, so that the descaling agent can be replenished into the tank 1 through the square tube 201.

[0035] As the descaling agent in the tank 1 gradually dissolves, the volume of the descaling agent will gradually decrease. Based on this, the present scheme is arranged at a position above the filter screen 4 in the tank 1 and is provided with a floating plate 3. The descaling agent is filled between the floating plate 3 and the filter screen 4. The floating plate 3 is provided with a through hole at the center position. The end face of the square tube 201 extending into the tank 1 is in communication with a rotating drum 7. The rotating drum 7 can block the bottom end of the square tube 201, so that the descaling agent in the feeding tank 2 can remain stable under normal circumstances. The through hole on the floating plate 3 is in vertical alignment with the rotating drum 7. As the water level in the tank 1 gradually rises, the floating plate 3 can move upward and be sleeved outside the rotating drum 7.

[0036] The floating plate 3 is elastically connected with a plug rod 18. The plug rod 18 can move along the diameter direction of the floating plate 3. A traction assembly cooperating with the plug rod 18 is arranged at the outer circumferential wall of the floating plate 3. When the floating plate 3 moves upward as the water level rises, the traction assembly can pull the plug rod 18 to gradually move one end of the plug rod 18 into the through hole. A limiting assembly cooperating with the plug rod 18 is arranged at the outer side wall of the rotating drum 7. When the floating plate 3 moves downward from the outside of the rotating drum 7, the plug rod 18 and the limiting assembly can drive the rotating drum 7 to rotate, so that the rotating drum 7 loses the blocking effect of the square tube 201, and the descaling agent in the feeding tank 2 can fall into the tank 1.

[0037] As shown in Figures 3-6 , a through circular hole is formed at the bottom end face of the square tube 201. The rotating drum 7 is located at the circular hole and is rotatably connected with the square tube 201 through a bearing. A top plate 701 is fixedly arranged at the top end of the rotating drum 7. A baffle 2011 abutting with the top plate 701 is fixedly arranged in the circular hole. Through holes 11 are formed in the top plate 701 and the baffle 2011. When the through hole 11 in the baffle 2011 is aligned with the through hole 11 in the top plate 701, the descaling agent in the feeding tank 2 can be guided out through the through holes 11 and fall into the tank 1.

[0038] As shown in Figures 1-11 , the traction assembly includes a group of rollers 6 (the number of rollers 6 is two) arranged at the outer circumferential wall of the floating plate 3. Figures 3-6 , Figure 8As shown, a recess for mounting the roller 6 is provided on the outer peripheral wall of the float plate 3, while a strip groove 104 that mates with the roller 6 is provided on the inner wall of the tank body 1. The roller 6 can be made of rubber so that the roller 6 is in close contact with the bottom surface of the strip groove 104. When the float plate 3 moves upward, the roller 6 can be rotated by the friction between the roller 6 and the bottom surface of the strip groove 104 (in actual operation, the roller 6 can also be replaced with a gear, and a rack that mates with the gear is installed in the strip groove 104. This method can drive the roller 6 to rotate more stably).

[0039] Furthermore, a connecting shaft 17 is provided at the axis of the roller 6. The connecting shaft 17 passes through the roller 6 and is fixedly connected to it. The connecting shaft 17 is rotatably engaged with the float 3. A drum 16 is sleeved on the outside of the connecting shaft 17. The drum 16 is located between the two rollers 6. (Refer to...) Figure 5 As shown, a vertical pole 1802 is fixedly installed on the insertion rod 18, and a traction rope 5 is fixedly installed between the vertical pole 1802 and the drum 16. Specifically, one end of the traction rope 5 is fixedly connected to the vertical pole 1802, and the other end of the traction rope 5 extends a certain distance away from the roller 6 and then turns back to the drum 16 and is fixedly connected to the outer wall of the drum 16. In this way, when the float 3 moves upward and drives the roller 6 to rotate, the connecting shaft 17 can drive the drum 16 to rotate through the snap-fit ​​assembly, thereby pulling the insertion rod 18 to move outward.

[0040] Reference Figure 6 As shown, the limiting component includes a straight groove 702 opened on the outer wall of the rotating cylinder 7. The straight groove 702 is parallel to the axis of the rotating cylinder 7. Further, two arc-shaped grooves 703 are symmetrically opened on one side of the straight groove 702 on the outer wall of the rotating cylinder 7. The opposite ends of the two arc-shaped grooves 703 are connected to the straight groove 702, and the close ends of the two arc-shaped grooves 703 are also connected to each other, so that one end of the insertion rod 18 can slide along the straight groove 702 and the two arc-shaped grooves 703.

[0041] from Figure 6 As can be seen, a baffle 8 is provided at the junction of the upper arc groove 703 and the straight groove 702. The bottom end of the baffle 8 is hinged to the rotating cylinder 7, and the top end of the baffle 8 is attached to the side wall of the straight groove 702. In the initial state, the baffle 8 is in an inclined state (the baffle 8 is inclined towards the straight groove 702) and can only deflect upward. In addition, a tension spring is installed between the bottom surface of the baffle 8 and the side wall of the straight groove 702 near the arc groove 703, so that the baffle 8 and the rotating cylinder 7 are elastically matched. When one end of the insertion rod 18 moves upward along the straight groove 702, it can cause the baffle 8 to deflect upward. When one end of the insertion rod 18 moves downward along the straight groove 702, the baffle 8 blocks the insertion rod 18 so that one end of the insertion rod 18 can slide from the straight groove 702 to the arc groove 703.

[0042] A protrusion 10 is arranged at the position where the two arc-shaped grooves 703 meet, the protrusion 10 elastically matches the rotating drum 7 and can move along the diameter direction of the rotating drum 7.

[0043] Initially, the tank 1 is filled with enough descaling agent, and the floating plate 3 is in the upper position of the descaling agent, so that the floating plate 3 is located at a higher position in the tank 1, at this time, as the water level of the tank 1 gradually rises, the floating plate 3 can be driven to move upwards, when the floating plate 3 is sleeved outside the rotating drum 7 and contacts the bottom of the square tube 201, the upward movement stops, but since the floating plate 3 moves upwards for a limited distance, the insertion rod 18 is still in the floating plate 3, so the floating plate 3 will not drive the rotating drum 7 to rotate during the downward movement of the floating plate 3;

[0044] As the use time increases, the volume of the descaling agent gradually decreases, so that the height of the descaling agent layer decreases, and the floating plate 3 will move downwards with the descaling agent, when the floating plate 3 moves to the preset position, as the tank 1 is filled with water, the floating plate 3 can move upwards for a long distance along with the water level, in this process, the connecting shaft 17 can be driven to rotate through the friction force between the roller 6 and the inner wall of the strip-shaped groove 104, so that the winding drum 16 is driven to rotate through the clamping assembly, so that the winding drum 16 can wind the traction rope 5, and the insertion rod 18 moves outward, so that one end of the insertion rod 18 is in the through hole, since the through hole and the straight groove 702 are vertically aligned with each other, during the upward movement of the floating plate 3 and the sleeving of the rotating drum 7 outside, the end of the insertion rod 18 away from the roller 6 can be inserted into the straight groove 702 and move upwards along the straight groove 702, later, when the water level in the tank 1 decreases, the floating plate 3 can move downwards, and through the arrangement of the baffle 8, one end of the insertion rod 18 can slide along the straight groove 702 into the arc-shaped groove 703 until it is on the top of the protrusion 10, in this process, the rotating drum 7 can be driven to rotate through the cooperation between the insertion rod 18 and the arc-shaped groove 703, so that the leakage hole 11 on the baffle 2011 is aligned with the leakage hole 11 on the top plate 701, so that the descaling agent in the feeding tank 2 can fall into the tank 1, which is conducive to supplementing the descaling agent in the tank 1, when the descaling agent in the feeding tank 2 falls completely, the protrusion 10 can move along the diameter of the rotating drum 7 and away from the insertion rod 18, so that the insertion rod 18 can be separated from the protrusion 10, and the floating plate 3 can continue to move downwards, during the downward movement of the floating plate 3 and the disengagement from the rotating drum 7, the insertion rod 18 can slide along the lower arc-shaped groove 703, so as to further drive the rotating drum 7 to rotate, so that the leakage hole 11 on the top plate 701 can be re-mismatched with the leakage hole 11 on the baffle 2011, which is conducive to subsequent filling of the descaling agent into the feeding tank 2.

[0045] In summary, this device can detect the height of the descaling agent layer through the float plate 3. When a certain amount of descaling agent is consumed, causing the float plate 3 to move downward to a designated position, the float plate 3 can cause the rotating drum 7 to rotate and release the descaling agent in the feeding tank 2 during its downward movement relative to the rotating drum 7. This enables automatic replenishment of the tank 1. Furthermore, the descaling agent is replenished during the drainage stage of the tank 1, allowing the falling descaling agent to fall into the water. This helps to buffer the falling descaling agent and prevent it from breaking due to impact. In addition, the flow of water also helps to ensure the uniform distribution of the descaling agent.

[0046] Reference Figure 5 , Figure 9 As shown, the snap-fit ​​assembly includes a snap-fit ​​block 19 that is elastically connected to the connecting shaft 17. Specifically, a groove is provided on the outer peripheral wall of the connecting shaft 17, and the snap-fit ​​block 19 is elastically connected to the groove by a spring. A slot is provided on the inner wall of the drum 16 to mate with the snap-fit ​​block 19. Figure 9 As can be seen, the end of the locking block 19 near the slot is an inclined surface 1901, which means that the engagement of the locking block 19 with the slot can only drive the drum 16 to rotate in one direction. In actual use, as the water level rises, the roller 6 can rotate, and the connecting shaft 17 drives the drum 16 to rotate to wind up the traction rope 5 through the engagement of the locking block 19 with the slot. Since the descaling agent is constantly consumed during use, the float 3 will be lower than its previous position after it falls. During the entire falling process, the roller 6 can rotate in the opposite direction, and the rod 18 will reset. During the process, the drum 16 can be pulled to rotate in the opposite direction and release the traction rope 5. However, when the traction rope 5 on the drum 16 is completely released, due to the elastic force between the insert rod 18 and the float 3, the engagement between the inclined surface 1901 on the locking block 19 and the locking groove is insufficient to drive the drum 16 to continue rotating to rewind the traction rope 5. This causes the roller 6 to drive the connecting shaft 17 to rotate independently. Through this structure, the traction rope 5 is not wrapped around the outside of the drum 16 each time the float 3 starts to move upward, thus enabling more accurate detection of the height of the descaling agent.

[0047] Reference Figure 4 As shown, a detection unit 22 is installed on the wall of the square tube 201. The detection unit 22 can be an infrared sensor or an ultrasonic sensor, etc., combined with... Figure 7As shown, the frame 13 is fixedly arranged at the inner wall of the rotary drum 7, the protrusion 10 is arranged through the rotary drum 7 and is in sliding fit with the rotary drum 7, and one end of the protrusion 10 extending into the frame 13 is integrally formed with a stop portion, so that the protrusion 10 is in T-shaped structure as a whole. The electromagnet 14 is installed in the frame 13, and a limiting spring is installed between the protrusion 10 and the electromagnet 14. The protrusion 10 is made of iron. When the electromagnet 14 is in the powered state, the suction force of the electromagnet 14 on the protrusion 10 can cause the protrusion 10 to separate from the plug rod 18 above the protrusion 10. Here, the control switch 12 is installed at the top of the protrusion 10 and at the position outside. The control switch 12 is electrically or signal connected with the above-mentioned detection unit 22, and the detection unit 22 and the electromagnet 14 are connected through a single-chip microcomputer, so that the detection unit 22 can control the electromagnet 14. In actual use, when the plug rod 18 is slid from the straight slot 702 into the arc-shaped slot 703 and falls on the protrusion 10, the control switch 12 can be pressed, so as to start the detection unit 22, so that the detection unit 22 is in the working state (in this way, the detection unit 22 does not need to be in the working state all the time, so as to be more energy-saving), and at this time, the descaling agent can fall into the tank body 1 through the square tube 201. When the falling of the descaling agent is completed, the detection unit 22 can detect this signal and control the electromagnet 14 to be in the powered state through the single-chip microcomputer, so that the protrusion 10 can move into the frame 13 and be separated from the plug rod 18, so that one end of the plug rod 18 can continue to move downward along the arc-shaped slot 703 and block the bottom of the square tube 201 again through the rotary drum 7. The related circuit connection structure is a mature technical means in the electrical field, which will not be described here.

[0048] Referring to Figure 1 As shown, the drain pipe 102 is communicated at the position outside the tank body 1 and close to the bottom end. When the tank body 1 is not used for a long time or the water temperature in the tank body 1 is high, the water in the tank body 1 needs to be discharged through the drain pipe 102 under the condition that the tank body 1 is not working, so as to avoid that the descaling agent is excessively dissolved.

[0049] Secondly, the blow-off pipe is arranged at the bottom end of the tank body 1, and the valve is installed on the blow-off pipe. The blow-off pipe can discharge the dirt in the tank body 1.

[0050] Referring to Figure 2 As shown, the floating plate 3 is uniformly provided with a plurality of penetrating circular holes, which is beneficial to the upward flow of water and the discharge of water through the water outlet pipe 101.
