Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of brine distribution, and particularly relates to a brine distribution system. BACKGROUND

[0002] When the content of calcium and magnesium ions in raw water exceeds the specified requirement, it will have an adverse effect on the RO membrane system or ion tank system in the later stage, which specifically manifests as causing RO membrane blockage or leading to excessive ion loading, and therefore a softening system needs to be designed in the pretreatment stage to solve the problem. The core component in the softening system is softening resin, which needs to be regenerated after continuous operation for 24 hours. The regeneration process needs to use brine of a specific concentration. The traditional brine preparation method is to realize saturation brine through a brine tank combined with a stirrer, that is, salt and water are put into the brine tank in proportion before each regeneration, and the saturation brine is formed after stirring by the stirrer, and then the saturation brine is diluted to the target concentration by a jet device and injected into the softener. In order to improve the brine preparation efficiency, the existing technology improves the brine tank, that is, a large amount of salt is placed in the brine tank, and a partition plate and a filter plate are used to separate the mixing area of the salt and water, so that the water can be mixed with the salt to form saturation brine after stirring after being transported to the brine tank, and the saturation brine can be extracted at any time without the need for separate configuration before each regeneration.

[0003] According to the search, the application for softening machine regeneration salt tank (CN217077069U) is disclosed, which comprises a tank body and a concentration detector. The tank body is provided with a partition plate, which divides the tank body into upper and lower parts. The partition plate and the upper part of the tank body form a storage cavity, and the partition plate and the lower part of the tank body form a liquid storage cavity. The partition plate is provided with a liquid leakage port communicating the liquid storage cavity and the storage cavity. The storage cavity is provided with a feed port communicating with the outside. The liquid storage cavity is provided with a liquid outlet port communicating with the outside. The concentration detector is arranged in the liquid storage cavity. The concentration detector is arranged on the upper end of the liquid outlet port. The concentration detector is connected with the outside for signal transmission.

[0004] Since the storage area of the salt and the mixing area of the water are in the same tank space, the salt is in a partially dissolved state in the water. When the water reaches saturation, the undissolved salt is deposited in the tank in the form of solid. The existing salt tank with a salt storage structure cannot obtain the remaining salt amount in the tank in real time. In the case that the water amount in the tank is sufficient, if the amount of solid salt is insufficient, the salt amount can be judged to be insufficient and replenished only after the concentration of the brine is detected to decrease by relying on the concentration meter, which leads to obvious hysteresis in the salt feeding and affects the regeneration effect of the softening resin.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0030] Please refer to Figures 1-7 , a salt water distribution system, comprising: a dissolved salt tank 100; a partition plate 101 installed in the dissolved salt tank 100, wherein the bottom of the partition plate 101 is provided with a first filter plate 102, and the partition plate 101 divides the dissolved salt tank 100 into a mixing area and a solution area; a second filter plate 103 arranged in the mixing area, wherein the second filter plate 103 divides the mixing area into a dissolving chamber and a filtering chamber; a detection plate 300 arranged in the filtering chamber, wherein the detection plate 300 is in contact with one side of the partition plate 101, the detection plate 300 is provided with a third filter plate 302 and a counterweight block 303, the third filter plate 302 is used to separate water and salt, and the counterweight block 303 is used to overcome the buoyancy of saturated salt water and drive the detection plate 300 to sink; The second filter plate 103 and the detection plate 300 jointly form a containing space in the filtering chamber for retaining solid salt; the detection plate 300 is configured to float up when the amount of solid salt in the containing space increases, and sink when the amount of solid salt decreases.

[0031] Specifically, the dissolved salt tank 100 is divided into a mixing area and a solution area by the partition plate 101, the mixing area is used for brine preparation, and the solution area is used for finished product storage, the first filter plate 102 at the bottom of the partition plate 101 utilizes the filtering property to allow the dissolved brine in the mixing area to enter the solution area, while blocking the undissolved solid particles, thereby realizing preliminary solid-liquid separation; the second filter plate 103 arranged in the mixing area subdivides the mixing area into a dissolution chamber and a filter chamber, the dissolution chamber mainly undertakes the function of brine dissolution, and the filter chamber mainly undertakes the function of solid salt interception, so that the dissolution process and the solid salt storage do not interfere with each other; the detection plate 300 in the filter chamber and the second filter plate 103 enclose a closed containing space therebetween, which is used to limit the storage range of the solid salt and does not affect the mixing of salt and water; the third filter plate 302 on the detection plate 300 adopts a structure with the property of water permeability and solid impermeability, thereby realizing physical separation of water and solid salt; the design of the counterweight 303 is based on the principle of buoyancy balance, and the gravity of the counterweight 303 can offset the buoyancy of the saturated brine acting on the detection plate 300, the accumulation thickness of the solid salt in the containing space directly determines the position of the detection plate 300, when the amount of salt increases, the accumulation thickness increases, and an upward supporting force is formed on the detection plate 300 to make it rise, when the amount of salt decreases, the accumulation thickness decreases, and the supporting force weakens, so that the detection plate 300 sinks accordingly, through the direct correlation between the lifting of the detection plate 300 and the accumulation thickness of the salt, real-time feedback of the salt amount state is realized.

[0032] In one embodiment, an automatic salt replenishing mechanism is further included, which comprises a storage cylinder 200 arranged outside the dissolved salt tank 100 and used for storing salt, a telescopic pipe 202 connected to the bottom of the storage cylinder 200 and extending into the dissolution chamber, a spiral conveying rod 203 arranged in the telescopic pipe 202, a first power source 205 installed on the storage cylinder 200, a rotating rod 204 connected to the power shaft of the first power source 205 and connected to the spiral conveying rod 203, and a control mechanism connected to the detection plate 300 and configured to control the start and stop of the first power source 205 to supplement salt to the dissolution chamber in response to the movement of the detection plate 300.

[0033] In the technical solution, the storage cylinder 200 is an independent external storage component, providing a continuous salt source for the dissolving chamber. The telescopic pipe 202 adopts a slidable nested structure. When the detection plate 300 rises or falls due to the change of the salt amount, the telescopic pipe 202 can synchronously adjust the length. The first power source 205 adopts a stepper motor, and can also adopt a servo motor. The first power source 205 provides power output for salt supplement. The power shaft of the first power source 205 drives the rotary rod 204 to rotate. Since the rotary rod 204 is connected with the screw conveying rod 203 through the telescopic groove, the rotary force of the rotary rod 204 can be synchronously transmitted to the screw conveying rod 203. The screw conveying rod 203 uses the propelling action of the screw blade to continuously and quantitatively convey the salt in the storage cylinder 200 to the dissolving chamber, so as to realize the precise feeding of the salt. The control mechanism is associated with the detection plate 300 through mechanical contact or signal induction. The upper and lower limit positions of the detection plate 300 are preset. When the salt amount in the accommodation space decreases and the detection plate 300 falls to the lower limit position, the detection plate 300 triggers the control mechanism to generate a start signal. The first power source 205 is started and drives the screw conveying rod 203 to supplement the salt. When the salt amount increases and the detection plate 300 rises to the upper limit position, the detection plate 300 triggers the control mechanism to generate a stop signal. The first power source 205 is closed. An automatic salt supplement closed-loop control based on the real-time state of the salt amount is formed, so as to ensure that the salt amount in the accommodation space is always maintained in a reasonable range.

[0034] In one embodiment, the bottom of the storage cylinder 200 is provided with a fixed pipe 201. The fixed pipe 201 is arranged in the dissolving chamber. The telescopic pipe 202 is slidably connected in the fixed pipe 201. The end of the telescopic pipe 202 away from the fixed pipe 201 penetrates the detection plate 300. When the detection plate 300 moves, the telescopic pipe 202 moves in the fixed pipe 201.

[0035] Specifically, the fixed pipe 201 is fixed to the bottom of the storage cylinder 200 and extends into the dissolving chamber, serving as a support and guide base of the telescopic pipe 202. The telescopic pipe 202 is nested in the fixed pipe 201 to form a slidable telescopic structure. The bottom end of the telescopic pipe 202 penetrates the detection plate 300 and forms linkage with the detection plate 300. When the detection plate 300 rises or falls due to the change of the salt amount, the telescopic pipe 202 is driven to slide in the fixed pipe 201 through mechanical connection, so that the length of the salt feeding channel is dynamically adjusted according to the position of the detection plate 300, and the communication between the storage cylinder 200 and the dissolving chamber is always maintained.

[0036] In one embodiment, the control mechanism comprises: a control cavity 304 opened on the detection plate 300; a moving seat 305 slidingly installed in the control cavity 304; a rack 306 installed on one side of the moving seat 305; a gear 309 arranged in the control cavity 304 and engaged with the rack 306; a second sensing unit 310 installed on the inner wall of one side of the control cavity 304 for detecting the rotating state of the gear 309; a connecting rod 307 installed on the gear 309, one end of the connecting rod 307 extending into the telescopic pipe 202 and being provided with a valve plate 308; wherein the second sensing unit 310 is connected with the first power source 205, the top end of the spiral conveying rod 203 is provided with a telescopic slot, and the end of the rotating rod 204 away from the first power source 205 is slidingly connected in the telescopic slot; the top and bottom of the moving seat 305 are both provided with a control rod 311, the top wall and the bottom wall of the control cavity 304 are both provided with a through hole, and the two control rods 311 respectively pass through the two through holes; the inner wall of the dissolved salt tank 100 is provided with two limiting plates 106, and the detection plate 300 is located between the two limiting plates 106; when the detection plate 300 moves to contact one limiting plate 106, the control rod 311 is extruded by the limiting plate 106 to drive the moving seat 305 to move, the connecting rod 307 and the valve plate 308 are driven to rotate through the rack 306 and the gear 309, so as to open or close the telescopic pipe 202, and the second sensing unit 310 detects the rotating state of the gear 309 to control the start and stop of the first power source 205.

[0037] Specifically, the two limit plates 106 serve as upper and lower limit position references of the detection plate 300, corresponding to the lower limit (salt needs to be supplemented) and the upper limit (supplementing salt is stopped) of the solid salt in the accommodation space, respectively, to provide position nodes for triggering actions; when the detection plate 300 rises or falls with the change of the salt amount to the position of the limit plate 106, the control rod 311 is in contact with and is pressed by the limit plate 106, converting the position signal of the detection plate 300 into the linear sliding motion of the moving seat 305; the linear motion of the moving seat 305 is converted into the rotary motion of the gear wheel 309 through the meshing transmission of the rack 306 and the gear wheel 309, and the rotary motion of the gear wheel 309 is directly transmitted to the valve plate 308 through the connecting rod 307, so that the valve plate 308 rotates synchronously with the gear wheel 309, realizing the opening or closing of the telescopic pipe 202 and completing the on-off control of the salt supplementing channel; the second sensing unit 310 is an angle sensor, and can also be a rotary sensor; the second sensing unit 310 indirectly judges the action direction of the valve plate 308 by detecting the rotary state of the gear wheel 309; when the gear wheel 309 rotates forward, the valve plate 308 is opened, and when the gear wheel 309 reverses, the valve plate 308 is closed; the second sensing unit 310 transmits signals to the first power source 205, forming the associated control that the valve plate 308 is opened when the gear wheel 309 rotates forward, and the power source starts to send salt; the valve plate 308 is closed when the gear wheel 309 reverses, and the power source stops sending salt, ensuring the cooperation of the on-off of the salt supplementing channel and the power output; the telescopic groove at the top end of the spiral conveying rod 203 is slidably connected with the rotary rod 204, adapting to the axial sliding of the telescopic pipe 202 with the detection plate 300, ensuring the continuous transmission of the power of the first power source 205 to the spiral conveying rod 203, and not limiting the lifting freedom of the detection plate 300, realizing the mutual non-interference of the salt supplementing power transmission and the salt amount detection.

[0038] In the above technical solution, the first power source 205 is a servo motor, and can also be a stepper motor; the second sensing unit 310 is connected with the first power source 205 through a PLC; when the salt amount in the accommodation space is insufficient, the detection plate 300 falls to the lower limit plate 106, the lower control rod 311 is pressed to drive the moving seat 305 to move upward, the rack 306 moves upward synchronously and drives the gear wheel 309 to rotate forward, the gear wheel 309 rotates forward to drive the valve plate 308 to rotate synchronously through the connecting rod 307, until the valve plate 308 rotates to a preset angle to completely open the telescopic pipe 202; after the second sensing unit 310 captures the forward rotation signal of the gear wheel 309, the signal is transmitted to the PLC, the PLC judges according to the preset logic that the salt needs to be supplemented, and at the same time sends a starting instruction to the first power source 205 to drive the rotary rod 204 to drive the spiral conveying rod 203 to send salt.

[0039] When the amount of salt in the accommodation space meets the standard, the detection plate 300 rises to the upper limit plate 106, the upper control rod 311 is pressed to drive the moving seat 305 to move downward, the rack 306 moves downward synchronously and drives the gear 309 to reverse; the second induction unit 310 detects the reverse signal of the gear 309 and transmits it to the PLC, the PLC judges that the salt supplement needs to be stopped, the reverse rotation of the gear 309 drives the valve plate 308 to rotate reversely through the connecting rod 307, until the valve plate 308 rotates to a preset angle to completely close the telescopic pipe 202, and the PLC sends a stop instruction to the first power source 205, and the salt feeding action is terminated.

[0040] In one embodiment, the water level detection mechanism is further included, and the water level detection mechanism comprises: a detection seat 500 arranged in the dissolving chamber; a detection groove opened at the bottom of the detection seat 500; a fourth filter plate 501 installed at the opening of the detection groove; a floating block 502 arranged in the detection groove; a second elastic member 503 installed between the inner wall of the detection groove and the floating block 502; and a third induction unit 504 arranged on the inner wall of the detection groove and used for detecting the position of the floating block 502 to determine the water level.

[0041] Specifically, the opening of the detection groove faces downward to allow water to flow naturally, the fourth filter plate 501 adopts a filter structure that is permeable to water but impermeable to solids, so that the water in the dissolving chamber can smoothly enter the detection groove to contact the floating block 502 while solid salt particles and impurities are intercepted; the floating block 502 is made of a material with a density less than that of water, so as to generate buoyancy in water; the second elastic member 503 is a compression spring, and can also be an elastic block; in the initial state, the buoyancy and the elastic member are balanced to stabilize the floating block 502 at a reference position corresponding to the water level; when the water level in the dissolving chamber rises, the buoyancy acting on the floating block 502 increases, breaking the initial balance and moving the floating block 502 upward; the third induction unit 504 is a pressure sensor, and can also be a contact sensor; after the floating block 502 moves upward and contacts the third induction unit 504, the third induction unit 504 obtains a contact signal; when the water level decreases, the buoyancy decreases, and the restoring force of the elastic member drives the floating block 502 to move downward to reset; the third induction unit 504 and the floating block 502 move away, and the contact signal of the third induction unit 504 disappears, which provides a basis for subsequent water supplement and realizes real-time feedback of the water level.

[0042] In the above technical solution, when the amount of salt in the mixing area is relatively large and the amount of water decreases, the height of the salt accumulated in the mixing area is greater than the water level, so that the water level cannot be determined in time; the floating block 502 is arranged below the detection plate 300, and when the water level decreases, the floating block 502 also decreases, so that the lifting of the floating block 502 can be used as a basis for determining the water level when the amount of salt is large and the amount of water is small.
