Description

Technical Field

[0001] This utility model belongs to the field of water purification technology, specifically relating to a treatment system for reducing the sulfate content in water. Background Technology

[0002] Concrete is typically made by mixing cement and other binders with sand, gravel, coarse and fine aggregates, and water in a certain proportion to form a porous concrete structure with capillary pores. Because the amount of water added during mixing is greater than the hydration water of the cement, the excess water remains in the capillary pores of the concrete as free water. Liquid corrosive media containing sulfate ions can enter the interior of the concrete structure through the capillary pores, thereby causing dual internal and external erosion of the concrete, damaging the concrete structure, and reducing the service life of the concrete.

[0003] Meanwhile, according to the concrete water standard "JGJ63-2019 Concrete Water Standard", the sulfate content of water used in prestressed concrete shall not exceed 600 mg / L, the sulfate content of water used in reinforced concrete shall not exceed 2000 mg / L, and the sulfate content of water used in cable concrete shall not exceed 2700 mg / L. The concrete preparation uses groundwater, surface water, drinking water, reclaimed water, equipment washing water from concrete enterprises, and seawater, among others. The most common sources are drinking water, surface water, and groundwater, and the sulfate content in these waters generally exceeds the standard.

[0004] In concrete preparation plants or project sites, before concrete preparation, operators first conduct experiments to test the ion content in the water. Then, the operators calculate and manually add chemicals to the water storage tank. This process is labor-intensive, and the sulfate ions and other ions in the water precipitate at the bottom after the reaction, making manual cleaning difficult and resulting in low work efficiency. Summary of the Invention

[0005] Based on this, this application provides a treatment system for reducing the sulfate content in water, in order to solve the problem that in concrete preparation plants or project sites, before concrete preparation, operators first conduct experiments to test the ion content in the water, and then calculate and manually add chemicals to the water storage tank. This is labor-intensive, and the sulfate ions in the water precipitate at the bottom after the precipitation reaction, making manual cleaning difficult and the work efficiency low.

[0006] The technical solution to the above-mentioned technical problems in this application is as follows:

[0007] A treatment system for reducing sulfate content in water includes: a mixing tank, a drug storage device, and a detection device. The mixing tank is provided with a first inlet, a stirring assembly, and a sludge scraping assembly disposed at the bottom of the mixing tank. The sludge scraping assembly includes a scraper, a drive rod, and a motor. The motor is disposed on one side of the mixing tank. One end of the drive rod is connected to the motor, and the other end passes through the scraper and is rotatably connected to the side of the mixing tank opposite to the motor. The scraper is capable of reciprocating along the extension direction of the drive rod. The drug storage device includes a main drug compartment connected to the first inlet. The detection device includes a first weight detector and an ion detector. The first weight detector is disposed at the outlet of the main drug compartment for weighing the drug entering the first inlet. The ion detector is disposed in the mixing tank for detecting the ion content in the mixing tank.

[0008] Preferably, the mixing tank is provided with a second inlet and a pH detector. The pH detector is installed on the side wall of the mixing tank to obtain the pH information of the water. The drug storage device also includes an excipient compartment connected to the second inlet.

[0009] Preferably, a volume detector is provided in the mixing tank, and the volume detector is used to detect the volume of water in the mixing tank.

[0010] Preferably, the system further includes a transfer tank, the inlet of which is connected to the outlet of the batching tank, and the volume of the transfer tank is not less than the volume of the batching tank. The transfer tank is used to store the supernatant in the batching tank.

[0011] Preferably, the transfer tank is equipped with a filter element and a sealing plate. The cross-sectional dimension of the inlet of the transfer tank is smaller than that of the batching tank. The sealing plate is equipped with a sealing strip and is detachably installed at the inlet of the transfer tank to disconnect the liquid phase space between the transfer tank and the batching tank. The filter element is installed at the inlet of the transfer tank for solid-liquid separation.

[0012] Preferably, one end of the sealing plate is hinged to the side wall of the transfer tank where the inlet is provided, and the other end of the sealing plate is provided with a fixing member, which is detachably connected to the transfer tank and used to fix the sealing plate.

[0015] The technical solution adopted in this application can achieve the following beneficial effects:

[0016] By using a scraper to move the sludge back and forth, sediment is scraped from one side to the other, solving the problem of difficult and inefficient cleaning of sediment in the mixing tank.

Weight detection devices measure the amount of water added manually to the storage tank, solving the problems of high labor intensity, low efficiency, and significant human error, as well as the inability to control the proportion of added chemicals, leading to uncertainties in the determination of various ion contents in the water. Simultaneously, ion detection devices monitor the ion content in the water in real time, overcoming the difficulties of cumbersome manual testing, inaccurate detection, and the challenge of accurately determining and controlling the ion content in the water.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Please see Figures 1 to 9This application provides a treatment system for reducing sulfate content in water, comprising: a mixing tank 100, a drug storage device 300, and a detection device 400. The mixing tank 100 is provided with a first inlet 120, a stirring assembly 110, and a sludge scraping assembly disposed at the bottom of the mixing tank 100. The sludge scraping assembly includes a scraper 101, a drive rod 102, and a motor 103. The motor 103 is disposed on one side of the mixing tank 100. One end of the drive rod 102 is connected to the motor 103, and the other end passes through the scraper 101 and is rotatably connected to the mixing tank 100 relative to the motor 103. On one side of 03, the scraper 101 can slide back and forth along the extension direction of the drive rod 102; the drug storage device 300 includes a main drug compartment 310, which is connected to the first feed inlet 120; and the detection device 400 includes a first weight detection element 410 and an ion detection element 430. The first weight detection element 410 is disposed at the outlet of the main drug compartment 310 and is used to weigh the drug entering the first feed inlet 120. The ion detection element 430 is disposed in the mixing tank 100 and is used to detect the ion content in the mixing tank 100.

[0031] Specifically, the mixing tank 100 uses water storage equipment such as cement masonry, plastic water tank, or metal water tank, and is cylindrical, cuboid, or cube in shape, preferably cube. The mixing tank 100 is equipped with a cover plate, on which a first inlet 120 and a second inlet 130 are opened, with the first inlet 120 and the second inlet 130 located near the middle of the cover plate. A sludge scraping assembly is provided at the bottom of the mixing tank 100, which includes a scraper 101, a drive rod 102, and a motor 103. A groove 105 is provided at the bottom of the mixing tank 100, which is arranged along the extension direction of the water inlet of the mixing tank 100. The drive rod 102 is rotatably mounted in the groove 105 and passes through the scraper 101. The motor 103 is located near the drive rod 102 near the water inlet of the mixing tank 100. At one end of the sprue, the drive rod 102 is a threaded rod. When the motor 103 drives the drive rod 102 to rotate, the scraper 101 moves along the rotation of the drive rod 102 (for example, when the motor 103 drives the drive rod 102 to rotate clockwise, the scraper 101 moves away from the motor 103 along the drive rod 102; conversely, when the motor 103 drives the drive rod 102 to rotate counterclockwise, the scraper 101 moves closer to the motor 103 along the drive rod 102). Furthermore, both ends of the scraper 101 are provided with sliding blocks 106, and both sides of the groove 105 of the mixing tank 100 are provided with sliding grooves 104, and the sliding grooves 104 are parallel to the groove 105. The sliding blocks 106 at both ends of the scraper 101 are in sliding engagement with the sliding grooves 104.

[0032] A gate is installed at the bottom of one side of the batching tank 100. The gate is sealed to the batching tank. When it is necessary to clean the batching tank 100, the gate is opened (the gate can be slid upwards, and the gate is slidably set in the groove). Then the motor 103 is turned on to rotate, which drives the drive rod 102 to rotate, and drives the scraper 101 to move from the side away from the motor 103 to the side closer to the motor 103, thereby causing the sediment to slide.

[0033] The main reagent bin 310 is a frame made of steel pipe and other materials, set above the mixing tank 100. The outlet of the main reagent bin 310 is connected to the first inlet 120 through a pipe. A first weight detection element 410 is installed inside the pipe. The first weight detection element 410 includes a weighing body, which includes, but is not limited to, two electromagnetic flaps 108 hinged to the pipe. When closed, the two electromagnetic flaps 108 are flush and seal the pipe, and weigh the reagent on the electromagnetic flaps 108. After weighing, the electromagnetic flaps 108 flip downward and fit against the side wall of the pipe, so that the reagent falls into the first inlet 120. Furthermore, in order to solve the problem of reagent remaining on the electromagnetic flaps 108, causing errors in weighing and input, fans are installed on both sides of the outlet of the main reagent bin 310. The air outlet of the fan is tilted downward. When the electromagnetic flap 108 valve is closed, the fan is turned off. When the electromagnetic flap 108 valve is flipped downward, the fan is turned on. The fan is controlled by a trigger mechanism, including a trigger plate and a trigger cone. An isolation plate 107 is installed between the trigger plate and the trigger cone, and the isolation plate 107 is located on the lower end face of the fan. One end of the isolation plate 107 is equipped with a spring, and a pull rope 109 passes through the spring and is connected to one end of the isolation plate 107. The other end of the pull rope is connected to the upper end face of an electromagnetic flap 108. When the electromagnetic flap 108 is closed, the isolation plate 107 is located between the trigger plate and the trigger cone, and the fan is in a disconnected state. When the electromagnetic flap 108 flips downward, it pulls the spring downward, thereby compressing the spring and causing the isolation plate 107 to move away from the trigger plate and the trigger cone, so that the trigger plate and the trigger cone come into contact, thereby energizing the fan. When the electromagnetic flap 108 is closed, the spring returns to its original position, causing the isolation plate 107 to move, thereby breaking the contact between the trigger plate and the trigger cone.

[0034] The ion detection device 430 employs, but is not limited to, portable multi-parameter water quality analyzers, ion chromatographs, and online chloride and sulfate ion analyzers.

[0035] Further, water is introduced into the mixing tank 100 through the inlet. The operator turns on the stirring assembly 110, and the ion detector 430 detects sulfate and chloride ions in the water to obtain ion content information, which is then observed and received by the operator. The operator manually compares the ion content information with the standard contents of sulfate and chloride ions. Then, the outlet of the main reagent chamber 310 is opened, allowing the reagent to fall onto the first weight detector 410. After the operator adjusts the weight of the reagent to match the preset weight, the reagent is added into the mixing tank 100 through the first inlet 120. When the operator observes that the ion content information of the ion detector 430 is the same as the standard contents of sulfate and chloride ions, the stirring assembly 110 is stopped, and the supernatant flows out from the outlet of the mixing tank 100.

[0036] When cleaning the batching tank 100, open the gate to release the water in the batching tank 100 and turn on the motor 103 to make it rotate, which drives the drive rod 102 to rotate and move the scraper 101. This causes the sediment on the side of the batching tank 100 away from the motor 103 to slide to the other side. When the scraper 101 reaches the motor 103, the operator reverses the motor 103 to make the scraper 101 move back to its original position. By sliding back and forth multiple times, the problem of incomplete cleaning of sediment in the batching tank 100 is solved. Then, the motor is turned off, and the sediment accumulated near the motor 103 is manually cleaned out of the batching tank 100. After cleaning, the gate is closed.

[0037] The technical solution of the treatment system for reducing sulfate content in water adopted in this application can achieve the following beneficial effects:

[0038] By sliding the scraper 101 back and forth, the sediment is scraped from one side to the other, solving the problem of difficult and inefficient cleaning of sediment in the mixing tank 100. The ion detector 430 reduces human error and solves the problem of incorrect ion content caused by human operation. The first weight detector 410 weighs the water, solving the problem of high labor intensity, low work efficiency, and large human error in manually adding chemicals to the water storage tank, which makes it difficult to control the proportion of added chemicals and thus difficult to determine the content of various ions in the water. At the same time, the ion detector 430 monitors the ion content in the water in real time, solving the problems of cumbersome manual detection, inaccurate detection, and difficulty in determining the ion content in the water.

[0039] Based on the above scheme, the mixing tank 100 is provided with a second inlet 130 and a pH detector 440. The pH detector 440 is used to obtain the pH information of the water. The drug storage device 300 also includes an auxiliary drug compartment 320, which is connected to the second inlet 130. The detection device 400 also includes a second weight detection element 420, which is set at the outlet of the auxiliary drug compartment 320 and is used to weigh the drug entering the second inlet 130.

[0040] Specifically, the second inlet 130 is symmetrically arranged with the first inlet 120, and the connection method and structure between the second inlet 130 and the auxiliary reagent compartment 320 are the same as those between the first inlet 120 and the main reagent compartment 310. The main reagent compartment 310 stores calcium salts, including calcium chloride and calcium hydroxide. The auxiliary reagent compartment 320 stores pH adjusters, such as sodium carbonate and quicklime. The pH detector 440 uses, but is not limited to, an industrial online pH meter, a portable / pen-type pH meter, etc. After the operator obtains the pH information by observing the pH detector 440... The pH of the reagent in the main reagent chamber 310 is compared with that of the sulfate in the water. The outlet of the auxiliary reagent chamber 320 is opened, and the reagent in the auxiliary reagent chamber 320 is weighed and added to the mixing tank 100 in the same way as the main reagent chamber 310 for reaction. By setting up a second inlet 130 and an auxiliary reagent chamber 320, the problems of cumbersome operation, high labor intensity and large error of manually testing and adjusting the pH of the water are solved. When the reagent in the auxiliary reagent chamber 320 is added to adjust the pH, the reagent in the main reagent chamber 310 reacts with the sulfate more quickly and conveniently, thereby improving the sulfate removal efficiency in the water.

[0041] In a preferred embodiment of this application, a volume detector 140 is provided in the mixing tank 100, and the volume detector 140 is used to detect the volume of water in the mixing tank 100.

[0042] The volume detector 140 can be, but is not limited to, a water level detector. The stirring assembly 110 can be a device consisting of a rotating motor and a rotating shaft. One end of the rotating shaft is connected to the rotating motor, and the other end is rotatably connected to the side wall of the mixing tank 100 and perpendicular to the groove 105. The preset volume is adjusted and set according to the volume of the mixing tank 100. The operator obtains the volume information by observing the volume detector 140. When the preset volume is reached, the operator stops adding water and turns on the stirring assembly 110. When the supernatant flows out of the outlet of the mixing tank 100, if the volume detector 140 detects that the volume is less than the preset volume, the operator turns off the rotating motor. By setting the volume detector 140, the operator can ensure that the volume of water added each time is the same, solving the problem of inaccurate dosage of the reagent due to the difficulty in confirming the water ratio. At the same time, it solves the problem of uneven mixing of the reagent due to human error, improves convenience, makes the reagent in the mixing tank 100 more uniformly mixed, and accelerates the reaction between the reagent and sulfate.

[0043] Based on the above scheme, a transfer tank 200 is also included. The inlet of the transfer tank 200 is connected to the outlet of the mixing tank 100, and the volume of the transfer tank 200 is not less than the volume of the mixing tank 100. The transfer tank 200 is used to store the supernatant in the mixing tank 100.

[0044] The volume of the transfer tank 200 is much larger than that of the batching tank 100, and the bottom of the batching tank 100 is located at half the height of the transfer tank 200 (adjusted according to site requirements). The outlet of the batching tank 100 and the inlet of the transfer tank 200 are the same size, both smaller than the side cross-sectional dimensions of the batching tank 100. For example, the height of the outlet of the batching tank 100 is three-quarters the height of the side wall of the batching tank 100, where the bottom of the batching tank 100 is used to block sediment. The outlet of the batching tank 100 is located on the side wall adjacent to the stirring assembly 110.

[0045] In the above scheme, in order to solve the problem of incomplete solid-liquid separation, the transfer tank 200 is equipped with a filter element 150 and a sealing plate 160. The cross-sectional dimension of the inlet of the transfer tank 200 is smaller than that of the batching tank 100. The sealing plate 160 is equipped with a sealing strip and is detachably installed at the inlet of the transfer tank 200 to disconnect the liquid phase space between the transfer tank 200 and the batching tank 100. The filter element 150 is installed at the inlet of the transfer tank 200 for solid-liquid separation.

[0046] The filter element 150 is a detachable and replaceable filter screen. A snap-fit ​​groove is provided on the inlet of the transfer tank 200, and snap-fit ​​plates are installed around the filter screen. The snap-fit ​​plates are detachably connected to the snap-fit ​​groove. The sealing plate 160 can be detachably installed on either side of the filter element 150, preferably on the side of the filter element 150 away from the mixing tank 100. If it is installed on the side closer to the mixing tank 100, sufficient force is required to open it towards the water in the mixing tank 100, resulting in greater water resistance and making opening inconvenient. If it slides upwards, this is not a concern. When the mixing tank 100 is dispensing materials and the stirring assembly 110 is rotating, the sealing plate 160 is in a sealed state. After mixing is complete, the sealing plate 160 is opened, and the supernatant passes through the filter element 150 into the transfer tank 200 for temporary storage. By setting up the filter element 150 and the sealing plate, the problem of a large amount of sediment in the supernatant during solid-liquid separation is solved.

[0047] In one embodiment of this application, one end of the sealing plate 160 is hinged to the side wall of the transfer tank 200 where the water inlet is provided, and the other end of the sealing plate 160 is provided with a fixing member, which is detachably connected to the transfer tank 200 and used to fix the sealing plate 160.

[0048] Specifically, the fasteners are, but not limited to, bolts, nuts, clips, etc. The sealing plate 160 is preferably opened to the side. A push-pull rod is provided on the upper part of the sealing plate 160. The flipping of the sealing plate 160 is controlled by the push-pull rod. The push-pull rod is connected to the main server. The extension and retraction of the push-pull rod is controlled by the instructions output by the main server.

[0049] In another embodiment of this application, the inlet of the transfer pool 200 is provided with a U-shaped groove, the sealing plate 160 is slidably disposed in the U-shaped groove, and one end of the sealing plate 160 is provided with a driving member. The driving member is used to drive the sealing plate 160 to slide up and down in the vertical direction. The driving member includes an n-shaped frame and a telescopic rod. The n-shaped frame spans both sides of the U-shaped groove. One end of the telescopic rod is connected to the n-shaped frame, and the other end is connected to the sealing plate, and is used to drive the sealing plate to slide up and down in the vertical direction.

[0050] The driving component employs, but is not limited to, a hydraulic cylinder, a motor 103, or a telescopic rod. This driving component causes the sealing plate 160 to slide up and down along the U-shaped groove. The width of the sealing plate 160 is the same as the width of the U-shaped groove, and a sealing strip is installed inside the U-shaped groove. When the sealing plate 160 is inserted into the U-shaped groove, the sealing strip fits tightly against the sealing plate 160, solving the problem of water leakage at the connection between the sealing plate 160 and the U-shaped groove. Simultaneously, the up-and-down sliding mechanism solves the problem of difficulty in opening and closing the sealing plate 160.

[0051] The specific work steps are as follows:

[0052] The operator first opens the gate, turns on the motor 103 to drive the drive rod 102 to rotate, and makes the scraper 101 slide back and forth multiple times along the extension direction of the drive rod 102. Finally, when the scraper 101 returns to the side of the batching tank 100 away from the motor 103, the motor 103 is turned off, and the sediment in the batching tank is manually cleaned. After cleaning is completed, the gate is closed.

[0053] The operator adds water to the mixing tank 100 while the volume detector 140 detects the volume. When the volume information detected by the volume detector 140 is the same as the preset volume threshold, the operator stops adding water and turns on the stirring component 110 to start stirring.

[0054] When the mixing component 110 is stirring, the ion detection element 430 begins to detect the ion content information in the mixing tank 100 (at least sulfate and chloride ions in the water are detected), and the operator makes a judgment. When the ion content information in the water exceeds the preset threshold (set according to the concrete preparation standard), the operator opens the main reagent chamber 310, and the reagent falls onto the first weight detection element 410. The operator compares the first weight information with the preset threshold (a preset standard first weight information, i.e., the preset threshold, is given a range of ion content information; different ion content information corresponds to different preset thresholds). When the first weight information is the same as the preset threshold, the main reagent chamber 310 is closed, and the reagent is mixed evenly and reacted under the action of the mixing component 110. If the ion content information is less than the preset threshold, the operator opens the sealing plate 160 and simultaneously closes the mixing component 110.

[0055] The pH detector 440 is manually activated after the ion detector has finished its detection to acquire the pH information in the water. The operator then compares the pH information with a preset threshold (preset based on the optimal pH value for the reaction between the reagent in the main reagent chamber 310 and the ions in the water). If they are different, the auxiliary reagent chamber 320 is manually activated, and the reagent falls onto the second weight detection element 420. The operator compares the second weight information with the preset threshold (based on a given pH information range, the corresponding preset standard second weight information is the preset threshold; different pH information corresponds to different preset thresholds). When the second weight information matches the preset threshold, the auxiliary reagent chamber 320 is closed. Driven by the stirring component 110, the reagent is mixed evenly, and the water pH information is adjusted to the optimal reaction pH value.

[0056] Then the ion detector 430 continues to detect the ion content information in the water, which is then compared by the operator, and the above steps are repeated.

[0057] The automatic detection by ion detector 430 reduces human error and solves the problem of incorrect ion content caused by human operation mistakes. The weighing by first weight detector 410 solves the problem of high labor intensity, low work efficiency, and large human error in manually adding agents to the water tank, which makes it difficult to control the proportion of added agents and thus difficult to determine the content of various ions in the water. At the same time, the real-time monitoring of ion content in the water by ion detector 430 solves the problems of cumbersome manual detection, inaccurate detection, and difficulty in determining the ion content in the water.

[0058] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
