[0030] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0031] In this disclosure, unless otherwise stated, the terms "first," "second," etc., used herein are for distinguishing one element from another and do not have sequential or material significance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The foregoing definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0032] According to a specific embodiment of this disclosure, refer to Figures 1 to 5 As shown, a powder conveying device is provided, which includes a conveying pipe 1, a screw conveyor 2 and a baffle 4. One end of the screw conveyor 2 is rotatably supported on the conveying pipe 1, and the other end of the screw conveyor 2 is rotatably supported on the baffle 4. One end of the baffle 4 is fixed to the inner wall of the conveying pipe 1, and a discharge port 13 is formed between the other end of the baffle 4 and the conveying pipe 1. A crushing tooth 41 is provided on the side of the baffle 4 facing the screw conveyor 2 to cooperate with the screw conveyor 2 to crush powder agglomerates.

[0033] With the above technical solution, when conveying calcium oxide powder, the powder is fed in from one end of the feed inlet of the conveying pipe 1, and then the screw conveyor 2 rotates to feed the powder. During this process, the screw conveyor 2 drives the powder to tumble and rotate. At the same time, the blades on the screw conveyor 2 also break up the powder clumps below during rotation, thereby breaking up some of the clumps in the powder. Then, when the powder is transported to the end of the screw conveyor 2, the powder clumps are squeezed and rubbed against the baffle 4 and the crushing teeth 41 as the screw conveyor 2 moves forward, thereby grinding up the larger or harder clumps in the powder. Through the above settings, the powder clumps are prevented from clogging the conveying pipe 1 during the conveying process. The screw feeding method can also better control the amount of feed, and at the same time, the powder clumps are broken up, so that the calcium oxide can react better with the concentrated water, thereby improving the reaction processing efficiency.

[0034] In this disclosure, the powder conveying device may also include a drive motor 3, which is located outside the conveying pipe 1, and the output shaft of the drive motor 3 is connected to the rotating shaft of the screw conveyor 2 for transmission, thereby driving the screw conveyor 2 to rotate to achieve screw feeding. In specific use, any suitable method can be selected to drive the screw conveyor to rotate according to actual needs, and this disclosure does not impose any specific restrictions on this.

[0035] In this disclosure, the structure of the screw conveyor 2 can be appropriately selected according to actual needs. For example, a shafted screw conveyor or a shaftless screw conveyor can be selected. This disclosure does not impose any specific limitations on this.

[0036] In the specific embodiments provided in this disclosure, the conveying pipe 1 can be designed arbitrarily according to actual needs. In one embodiment, the conveying pipe 1 may include a conveying section 11 and a feeding section 12. The feeding section 12 is connected to the conveying section 11 and extends downward in the vertical direction. The feeding section 12 and the conveying section 11 are arranged at an angle and form a corner. The screw conveyor 2 is located inside the conveying section 11, and the baffle 4 is arranged at the corner. When the conveying pipe 1 is in use, the conveying section 11 and the feeding section 12 are integrated. After the calcium oxide powder is sent to the baffle 4 by the screw conveyor 2 for crushing, the powder falls naturally and enters the reaction mechanism 7 along the feeding section 12, thereby avoiding the accumulation of crushed powder under the baffle 4 and improving the conveying efficiency.

[0037] In this disclosure, the structure of the baffle 4 can be designed arbitrarily according to actual needs. In one embodiment, the lower edge of the baffle 4 can be formed with an inclined surface, which together with the inner wall of the conveying pipe forms a feeding port 13. The crushed calcium oxide powder is fed through the feeding port 13, which also serves as a screening function. By adjusting the structure of the lower edge of the baffle 4, the size of the feeding port 13 can be adjusted so that some incompletely crushed lumps cannot pass through the feeding port 13. Subsequently, the lumps are continuously crushed by the crushing teeth 41 under the push of the screw conveyor 2, thus avoiding the problem of incomplete crushing of some lumps. In addition, multiple crushing teeth 41 can be provided, and the multiple crushing teeth 41 are arranged at intervals in the vertical direction, thereby making the crushing more uniform.

[0038] Based on the above technical solutions, this disclosure also provides a reverse osmosis concentrate softening device, for reference... Figures 2 to 5 As shown, the reverse osmosis concentrate softening device includes a chemical storage mechanism 5, a water storage mechanism 6, a reaction mechanism 7, and the aforementioned powder conveying device. The water storage mechanism 6 is connected to the reaction mechanism 7 and is used to inject concentrate into the reaction mechanism 7. The chemical storage mechanism 5 is connected to the reaction mechanism 7 through the powder conveying device and is used to inject calcium oxide powder into the reaction mechanism 7.

[0039] With the above technical solution, when the reverse osmosis concentrate softening device is in use, the concentrate to be softened is injected into the reaction unit 7 through the water storage mechanism 6. Simultaneously, calcium oxide powder is pre-stored in the chemical storage mechanism 5 and then injected into the reaction unit 7 through the aforementioned powder conveying device. The calcium oxide mixes and reacts with the concentrate to remove metal ions contained in the concentrate, thus completing the softening process. Furthermore, the reverse osmosis concentrate softening device provided in this disclosure also has the above-mentioned characteristics; to avoid repetition, it will not be described in detail here.

[0040] In this disclosure, the reaction mechanism 7 may include a reaction chamber 77 and a reaction vessel 71. The reaction vessel 71 is assembled in the reaction chamber 77 and is connected to the drug storage mechanism 5 and the water storage mechanism 6. During the softening process, concentrated water and calcium oxide are injected into the reaction vessel 71 for reaction treatment. The calcium oxide reacts with the metal ions in the concentrated water to form a precipitate, completing the softening process. The reaction chamber 77 is located outside the reaction vessel 71 to protect the reaction vessel 71 and other components. In use, the delivery pipe 1 and the concentrated water pipe 63 pass through the reaction chamber 77 and are connected to the reaction vessel 71. After the reaction is completed, the softened concentrated water and the precipitate are discharged together. Then, the precipitate can be filtered out. The filtered precipitate can be used for desulfurization, etc., to achieve recycling. The reaction vessel 71 may be configured as a conical structure. The conical structure of the reaction vessel 71 can make the material reaction more stable. The specific design can be selected according to actual needs, and this disclosure does not impose specific limitations in this regard.

[0041] In the specific embodiments provided in this disclosure, the reverse osmosis concentrate softening device may further include a blower 8 and a duct 82. The blower 8 is installed outside the reaction tank 77. The reaction vessel 71 has a connecting port 76 and a chemical inlet 78 and an outlet 79 arranged opposite to each other. The connecting port 76 is located between the chemical inlet 78 and the outlet 79 and is arranged close to the outlet 79. One end of the duct 82 extends into the interior of the reaction vessel 71 through the connecting port 76, and the other end is connected to the blower 8. During the softening process, the delivery pipe 1 is connected to the reaction vessel 71 through the chemical inlet 78. The outlet 79 is used to discharge the concentrate after the reaction is completed. The blower 8 delivers... The outlet is connected to the connecting port 76 via the air duct 82. Since the connecting port 76 is located near the discharge port 79, when the softening reaction occurs in the reactor 71, the blower 8 is activated, blowing external airflow into the reactor 71 through the connecting port 76. This causes the mixed solution in the reactor 71 to tumble and rotate, further accelerating the dissolution of calcium oxide in the concentrated water and increasing the reaction rate. Simultaneously, the gas blown into the reactor 71 by the blower 8 forms bubbles in the concentrated water solution, creating a boiling-like effect in the liquid, thus preventing the precipitate formed by the reaction of calcium oxide and concentrated water from accumulating and clogging at the discharge port 79. Furthermore, the reverse osmosis concentrated water softening device may also include a heater 81. The heater 81 is located inside the reaction chamber 77 and connected to the air duct 82. The heater 81, located at the lower part of the air duct 82, heats the gas blown in by the blower, further accelerating the dissolution of the calcium oxide powder. The heater 81 is located inside the reaction chamber 77 for protection, while the blower 8 is located outside the reaction chamber 77 to ensure unobstructed airflow. The end of the air duct 82 closest to the reactor 71 can also be connected to a check valve 83 to prevent concentrated water from flowing back into the air duct 82.

[0042] In the specific embodiments provided in this disclosure, the structure of the reactor 71 can be designed arbitrarily according to actual needs. In one embodiment, a threaded groove 74 for guiding water flow is provided on the inner wall of the reactor 71, making it easier for the concentrated water to move under the influence of airflow after being injected into the reactor 71, thereby accelerating the dissolution of calcium oxide. In addition, a guide section 84 can be formed at the end of the air duct 82 connected to the reactor 71. The guide section 84 extends into the reactor 71 and extends tangentially along the threaded groove 74, making it easier to drive the concentrated aqueous solution to rotate when the airflow is blown in, thereby improving the dissolution effect.

[0043] In the specific embodiments provided in this disclosure, the water storage mechanism 6 can be designed arbitrarily according to actual needs. In one embodiment, the water storage mechanism 6 may include a water storage tank 61, a water pump 62, and a concentrate pipe 63. The inlet of the water pump 62 is connected to the water storage tank 61, and the outlet of the water pump 62 is connected to the reaction vessel 71 through the concentrate pipe 63. The concentrate pipe 63 is connected to the upper part of the reaction vessel 71. During water softening treatment, the concentrate is pre-stored in the water storage tank 61. After the treatment begins, the water pump 62 draws water from the concentrate tank and injects it into the reaction vessel 71 for reaction treatment. Connecting the concentrate pipe 63 to the upper part of the reaction vessel 71 allows the concentrate to fall during injection, which allows the concentrate to better mix and react with the calcium oxide powder during the falling and splashing process.

[0044] In this disclosure, the drug storage mechanism 5 may include a drug storage tank 51, which is connected to the reactor 71 via a powder conveying device. During concentrated water softening treatment, the calcium oxide powder stored in the drug storage tank 51 enters the reactor 71 through the powder conveying device, preventing the calcium oxide powder from becoming damp and clumping, thus affecting the concentrated water treatment effect. Furthermore, to facilitate the addition of drug powder to the drug storage tank 51, a lid 52 may be provided at the top of the drug storage tank 51. The lid 52 and the drug storage tank 51 may be connected by a hinge; this disclosure does not impose specific limitations on this aspect.

[0045] In the specific embodiments provided in this disclosure, the reverse osmosis concentrate softening device may further include a controller 9, a powder conveying device including a drive motor 3, a first detection device 91 connected to a water storage tank 61, and both the drive motor 3 and the first detection device 91 being electrically connected to the controller 9; a drain pipe 72 is also connected to the lower end of the reactor 71, a drain valve 73 is connected to the drain pipe 72, and a second detection device 92 is connected to the reactor 71, with both the drain valve 73 and the second detection device 92 being electrically connected to the controller 9. During processing, the first detection device 91 detects the concentration of metal ions in the concentrate in the water storage tank 61, and then the controller 9 controls the rotation speed of the drive motor 3 according to the concentration of metal ions in the water storage tank 61, thereby controlling the calcium oxide feeding speed to achieve quantitative dosing. The second detection device 92 is used to detect the concentration of metal ions in the reactor 71. When the concentration of metal ions in the mixed solution reaches the discharge standard, the controller 9 then controls the drain valve 73 to open, discharging the treated concentrate in the reactor 71, thus achieving automated control of the drainage process. The first detection device 91 and the second detection device 92 can be appropriately selected according to actual needs. For example, both the first detection device 91 and the second detection device 92 can be configured as conductivity meters, and this disclosure does not impose specific limitations on this. In addition, any suitable connection method can be used between the reaction vessel 71 and the drain pipe 72. In one embodiment, in order to facilitate cleaning of the drain pipe 72, a threaded connection can be used between the drain pipe 72 and the reaction vessel 71, and this disclosure does not impose specific limitations on this.

[0046] In this disclosure, an exhaust pipe 75 may also be connected to the reactor 71. The exhaust pipe 75 is connected to the internal space of the reactor 71. During the reaction, the blower 8 will blow hot air into the reactor 71. At the same time, calcium oxide will generate heat when it dissolves in water. The exhaust pipe 75 can ensure that the pressure inside the reactor 71 is stable during the reaction and avoid the danger caused by the increased pressure inside the reactor 71 due to heat.

[0047] refer to Figures 1 to 5 As shown, the specific implementation principle of this embodiment is as follows: When softening concentrated water, the concentrated water and calcium oxide powder are pre-stored in the water storage tank 61 and the chemical storage tank 51, respectively. After the treatment begins, the controller 9 controls the drive motor 3 to start and drive the screw conveyor 2 to rotate for screw feeding. At the same time, the end of the screw conveyor 2 cooperates with the baffle 4 to squeeze and break up the calcium oxide clumps, thereby solving the problem that the calcium oxide absorbs water and clumps, affecting the reaction effect. At the same time, the water pump 62 draws concentrated water from the water storage tank 61 and injects it into the reaction vessel 71. The concentrated water and calcium oxide powder react in the reaction vessel 71 to remove the metal ions contained in the concentrated water and complete the softening. During this process, the blower 8 and the heater 81 start to blow hot air into the concentrated water mixture solution, thereby further accelerating the dissolution and mixing of calcium oxide powder and concentrated water and improving the reaction efficiency. When the second detection device 92 detects that the metal ion concentration in the mixture solution in the reaction vessel 71 reaches the emission standard, the controller 9 controls the drain valve 73 to open and discharge the treated solution. Then, the precipitate in the solution is filtered out to complete the softening.

However, the present disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0049] It should also be noted that the specific technical features described in the above embodiments can be combined in any suitable manner, provided that there is no contradiction.

[0050] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
