Common admixtures include water reducers, early strength agents, retarders, antifreeze agents, pumping agents, etc. Common production equipment is mainly reactors, which are prepared by adding a variety of chemical powders into the water of the reactor at different water temperatures and then stirring and mixing.

[0014] Furthermore, a method for using a reactor for a high-performance concrete admixture is provided, based on the above-mentioned reactor for a high-performance concrete admixture, and the specific steps are as follows:

[0015] Step 1: water is injected into the outer shell through the water injector, and the buoyancy ring is affected by its own buoyancy and gradually moves upward following the position of the water flow, and then the chemical powder is placed between the grinding table and the grinding shell, and the second electronically controlled motor drives the rotating shaft through the second gear set, and the rotating shaft drives the grinding table through the transmission belt, so that the grinding table and the grinding shell rotate relative to each other and grind the packaged materials, and then the chemical powder enters the storage chamber of the hollow shaft;

[0016] Step 2: The output shaft of the first electronically controlled motor transmits the adjacent threaded rod through the first gear set, and the threaded rod rotates and drives the sliding plate to move up and down. With the movement of the sliding plate, after the first blocking block loses its blocking of the adjacent discharge port and the second blocking block loses its blocking of the adjacent connecting holes on the partition plate, the gas in the hollow shaft gas storage chamber enters the storage chamber along the connecting holes, and the gas in the hollow shaft sprays the chemical powder in its storage chamber into the housing through the discharge port and the discharge hole of the sliding plate;

[0017] Step 3: During the rotation of the rotating shaft, the rotating shaft drives the rotating disk through the second gear set and the gear ring, and the rotating disk drives the stirring rod to rotate, and the stirring rod stirs the chemical powder and water in the shell;

[0018] Step 4: After the admixture preparation reaction is completed, the admixture is discharged through the collection pipe and falls into the collection shell on the discharge tray. The liquid level of the admixture inside and outside the shell gradually decreases, and the buoyancy ring drives the adjacent first scraper and the adjacent second scraper to move downward through the connecting rod, and cooperates with the deformation of the elastic sheet to scrape off the impurities on the inner wall of the shell layer by layer;

[0019] Step 5: During the process of collecting the admixture, the first pressure plate and the second pressure plate are moved to divert the admixture in the collection pipe when the liquid level of the admixture inside and outside the shell is high, and to compensate the amount of the admixture in the collection shell after the liquid level of the admixture inside and outside the shell drops;

[0020] Step 6: When the additive in the shell is discharged and collected, if it is necessary to stop using the device, reset the device and turn off the power supply, and then clean the device for the next use.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows: 1. The present invention directly injects the chemical powder into the water flow in the shell through the discharge ports distributed in a linear array on the hollow shaft, so that the chemical powder is evenly distributed in each water layer in the shell, preventing part of the chemical powder from floating on the water surface and temporarily unable to sink into the water, causing the chemical powder to lose the optimal temperature time for fusion with water, thereby causing the quality of the admixture to decrease;

[0022] 2. Divert the water flow in the collecting pipe through the diversion pipe to reduce the water flow pressure in the collecting pipe. When the liquid level of the admixture inside and outside the shell is high, the pressure and discharge volume of the admixture are reduced. When the liquid level of the admixture inside and outside the shell drops, more admixture is squeezed into the collecting pipe by the first pressure plate to increase the pressure and discharge volume of the admixture when it is discharged, so as to prevent the different amounts of admixtures in different collecting shells when the liquid level of the admixture inside and outside the shell changes, thereby affecting the effect of subsequent use.

DETAILED DESCRIPTION

[0036] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0037] When adding a variety of chemical powders into a reactor with existing admixtures, the operator directly adds the chemical powders into the reactor to react with water. At the moment when the chemical powders come into contact with the water surface, due to the small density and light weight of the chemical powders, a part of the chemical powders will float on the water surface and cannot sink into the water, thereby reducing the amount of chemical powders that react with water, causing the chemical powders floating on the water surface to be temporarily unable to merge with water. Different chemical powders require different temperatures when merging with water, which will cause the chemical powders to lose the optimal temperature time for merging with water, thereby causing the quality of the admixture to deteriorate.

A hollow shaft 1004 is arranged between the distributed threaded rods 1003, and a partition plate 1005 is fixedly connected inside the hollow shaft 1004. The partition plate 1005 divides the cavity inside the hollow shaft 1004 into two parts: a material storage chamber and an air storage chamber. The material storage chamber of the hollow shaft 1004 is connected to the gap between the grinding table 3 and the grinding shell 301, and is used to directly guide the chemical powder to the bottom of the outer shell 1 to prevent the chemical powder from adhering to the water surface. The air storage chamber of the hollow shaft 1004 is connected to an external air injection device, and the external air injection device is electrically connected to the control panel. The hollow shaft 1004 is provided with discharge ports 1006 distributed in a linear array and connected to its material storage chamber. The hollow shaft 1004 is sealed and slidably connected with a sliding disk 1007. The threaded rod 1003 is threadedly connected to the sliding disk 1007. The sliding disk 1007 is provided with a discharge hole, and the discharge port 1006 is connected and matched with the discharge hole.

[0039] like Figure 7As shown, a trigger ball 2 is slidably connected in the sliding disk 1007, and an elastic member is fixedly connected between the sliding disk 1007 and the trigger ball 2, wherein the elastic member is a compression spring, and an extrusion portion 201 is provided at a position of the sliding disk 1007 near the hollow shaft 1004, and guide slopes are provided on the upper and lower sides of the extrusion portion 201, and the partition plate 1005 is fixedly connected with elastic telescopic rods 202 distributed in a linear array, and the elastic force of the spring in the elastic telescopic rod 202 is less than the elastic force of the elastic member on the trigger ball 2, so that when the trigger ball 2 squeezes the adjacent sliding block 203, the telescopic end of the adjacent elastic telescopic rod 202 is contracted, and the telescopic end of the elastic telescopic rod 202 is fixedly connected with a sliding block 203 that is extruded and matched with the trigger ball 2, and the sliding block 203 is sealingly and slidably connected to the hollow shaft 1004, and a first blocking block 204 is fixedly connected to the lower side of the sliding block 203, and the first blocking block 204 is truncated cone-shaped, and the diameter of the first blocking block 204 gradually decreases from left to right (the moving direction at this point is Figure 7 The front view is taken as a reference), the first blocking block 204 is sealed with the adjacent discharge port 1006, the hollow shaft 1004 is slidably connected with sliding rods 205 distributed in a linear array and all of which are pressed and matched with the extrusion part 201, the position of the sliding rod 205 near the extrusion part 201 is spherical, which is used to be pressed and matched with the guide slope of the extrusion part 201, and an elastic member is fixed between the sliding rod 205 and the partition plate 1005, wherein the elastic member is a compression spring, when the guide slope of the extrusion part 201 gradually moves upward and squeezes the sliding rod 205, the sliding rod 205 is pressed to move to the right and causes its elastic member to be compressed (the moving direction at this point is Figure 7 The front view is taken as a reference), the position of the sliding rod 205 away from the extrusion part 201 is fixedly connected to the second blocking block 206, the second blocking block 206 is truncated, and the diameter of the second blocking block 206 gradually decreases from left to right (the moving direction at this point is Figure 7 The partition plate 1005 is provided with connecting holes distributed in a linear array, and the connecting holes are used to connect the material storage chamber and the gas storage chamber. The connecting holes cooperate with the adjacent second blocking block 206 to open the connecting holes when the discharge holes of the sliding plate 1007 are connected with the adjacent discharge port 1006, so as to use gas to spray out the chemical powder.

[0040] like Figure 2 and Figure 3As shown, a grinding table 3 is rotatably connected to the upper portion of the outer shell 1 near the feeding plate 107, a grinding shell 301 is fixedly connected to the outer shell 1 near the grinding table 3, a plurality of groups of circumferentially distributed grinding blocks are fixedly connected to the opposite sides of the grinding table 3 and the grinding shell 301, the grinding table 3 is in the shape of an inverted truncated cone, the gaps between all the grinding blocks on the grinding table 3 and all the grinding blocks on the grinding shell 301 decrease successively from top to bottom, a plurality of groups of circumferentially distributed grinding blocks on the grinding table 3 and a plurality of groups of circumferentially distributed grinding blocks on the grinding shell 301 are staggeredly distributed, and are used to grind chemical powders located between the grinding table 3 and the grinding shell 301, a gap is provided between the grinding table 3 and the grinding shell 301, and the bearing shell 109 is connected to the gap.

[0041] like Figure 4 , Figure 8 and Fig. 9 As shown, a second electrically controlled motor 4 electrically connected to the control panel is fixedly connected to a position of the outer shell 1 near the grinding shell 301, a rotating shaft 401 is rotatably connected to a position of the outer shell 1 near the second electrically controlled motor 4, the rotating shaft 401 and the output shaft of the second electrically controlled motor 4 are driven by a second gear set, wherein the second gear set is composed of two mutually meshing spur gears, one of which is fixedly connected to the output shaft of the second electrically controlled motor 4, and the other is fixedly connected to the rotating shaft 401, the rotating shaft 401 and the grinding table 3 are driven by a transmission belt, a rotating disk 402 is rotatably connected to a position of the outer shell 1 near the rotating shaft 401, the rotating disk 402 and the second gear set are driven by a gear ring, the rotating disk 402 is fixedly connected to stirring rods 403 uniformly distributed in the circumference and all located in the outer shell 1, the lower size of the stirring rods 403 is larger than the upper size thereof, and the stirring rods 403 are used to stir the additive at the bottom of the inner shell 1 to reduce the amount of additive deposition at the bottom of the inner shell 1.

[0042] When the device is needed, the operator adds a variety of chemical powders between the grinding table 3 and the grinding shell 301 in sequence according to different temperatures, and controls the second electronically controlled motor 4 to start through the control panel. The output shaft of the second electronically controlled motor 4 drives the rotating shaft 401 to rotate through the second gear set, and the rotating shaft 401 drives the grinding table 3 to rotate through the transmission belt, and the grinding table 3 drives the grinding block thereon to rotate. The grinding block of the grinding table 3 and the grinding block of the grinding shell 301 rotate relative to each other and stir the chemical powders entering therebetween to prevent the chemical powders from agglomerating and then being added to water. The agglomeration of the chemical powders causes part of the powders wrapped inside to be unable to contact with water, thereby affecting the quality of the additive. At the same time, during the rotation of the rotating shaft 401, the rotating shaft 401 drives the rotating disk 402 to rotate through the second gear set and the gear ring, and the rotating disk 402 drives the stirring rods 403 evenly distributed circumferentially to rotate, so as to stir the chemical powders and water in the outer shell 1, so that the water and the chemical powders are fully mixed, thereby improving the reaction rate during the preparation of the additive.

[0043] After the chemical powder passes between the grinding table 3 and the grinding shell 301, the chemical powder enters the storage chamber of the hollow shaft 1004. At this time, the control panel controls the external gas injection equipment to inject gas into the gas storage chamber of the hollow shaft 1004, and the control panel controls the two first electronically controlled motors 1002 to start synchronously. The output shaft of the first electronically controlled motor 1002 rotates back and forth and drives the adjacent threaded rod 1003 to rotate back and forth through the first gear set. The two threaded rods 1003 rotate back and forth and drive the sliding disk 1007 to slide back and forth up and down. The sliding disk 1007 drives its internal parts to slide back and forth up and down. When the sliding disk 1007 drives the trigger ball 2 to move to align with a sliding block 203, the elastic part of the trigger ball 2 pops out and drives it to squeeze the adjacent sliding block 203, so that the sliding block 203 moves and squeezes the telescopic end of the adjacent elastic telescopic rod 202 to shrink. The sliding block 203 moves during the movement. During the process, the adjacent first blocking block 204 is driven to move, so that the first blocking block 204 loses the blocking of the adjacent discharge port 1006. At the same time, the extrusion part 201 squeezes the adjacent sliding rod 205, and the elastic part of the sliding rod 205 contracts and drives the adjacent second blocking block 206 to move. The second blocking block 206 loses the blocking of the adjacent connecting holes on the partition plate 1005, so that the storage chamber of the hollow shaft 1004 is connected with its gas storage chamber. At this time, if there is no chemical powder in the storage chamber of the hollow shaft 1004, the gas in the gas storage chamber of the hollow shaft 1004 is discharged to the discharge hole of the sliding disk 1007 through the unblocked connecting holes and the discharge port 1006, and then the gas enters the water in the outer shell 1 through the discharge hole, so that bubbles are formed in the water in the outer shell 1, thereby accelerating the flow rate of the water flow in the outer shell 1, thereby improving the mixing efficiency of the water flow and the chemical powder added in the previous wave.

[0044] When the chemical powder enters the storage chamber of the hollow shaft 1004, and the first blocking block 204 loses its blocking of the adjacent discharge port 1006, and the second blocking block 206 loses its blocking of the adjacent connecting holes on the partition plate 1005, the gas in the gas storage chamber of the hollow shaft 1004 enters the storage chamber along the connecting holes, and the gas of the hollow shaft 1004 sprays the chemical powder in its storage chamber into the housing 1 through the discharge port 1006 and the discharge holes of the sliding plate 1007 (when the sliding plate 1007 is not in contact with the sliding block 206). 03, gas is continuously injected into the gas storage chamber, so that the gas storage chamber is filled with high-pressure gas), accompanied by the up and down movement of the sliding disk 1007, the chemical powder is sprayed from top to bottom into the water layers at different heights in the outer shell 1, so as to prevent the chemical powder from adhering to the water surface when added, and at the same time, the chemical powder is evenly distributed in each layer of the water, thereby preventing the water flow from wrapping the chemical powder and causing it to agglomerate, and the internal powder cannot contact with water and react, resulting in different chemical powder contents in each layer of water, thereby affecting the quality of the admixture after manufacture.

[0045] When the admixture is prepared, the operator draws out the admixture through the drain port of the outer shell 1, then resets the device and turns off the external gas injection equipment, the water injector 1001, the first electronically controlled motor 1002 and the second electronically controlled motor 4 through the control panel, and then cleans the device for the next use.

[0046] In the existing admixture preparation process, different admixture preparation raw materials will produce different by-products after contacting and reacting with water. For example, some water reducers will produce a large amount of salt crystals such as calcium salts and sodium salts after preparation. A large amount of unreacted raw materials, by-products or crystals will remain on the inner wall of the reactor, which will affect the next admixture preparation. While a large amount of impurities will remain in the next admixture, it may also cause the raw material content in the next admixture to increase, thereby affecting the quality of admixture preparation.

[0047] Embodiment 2: Based on embodiment 1, Figure 4 and Fig. 9 As shown, it also includes a sliding frame 5 evenly distributed in the circumference, and the sliding frames 5 evenly distributed in the circumference are respectively slidably connected to adjacent stirring rods 403. The upper side of the sliding frame 5 is slidably connected to a first scraper 501, and the first scraper 501 is fixedly connected to a second scraper 503 through a symmetrically distributed connecting rod 502. The second scraper 503 is located below the water surface. When cleaning the inner wall of the shell 1, it can cooperate with the water flow to scrape off the generated by-products, precipitates or crystals. The first scraper 501 and the adjacent second scraper 503 are both connected to the inner wall of the shell 1. The wall is fitted to scrape off the by-products, precipitates or crystals generated during the chemical powder reaction. A buoyancy ring 504 is provided between the circumferentially evenly distributed sliding frame 5 and the circumferentially evenly distributed second scraper 503. The circumferentially evenly distributed sliding frame 5 and the circumferentially evenly distributed second scraper 503 are squeezed and matched with the buoyancy ring 504, and are used to drive the sliding frame 5 and the parts thereon to move up and down by buoyancy. An elastic sheet 6 is fixedly connected between the stirring rod 403 and the adjacent first scraper 501, and is used to make the first scraper 501 move horizontally.

[0048] In the process of extracting the admixture inside the shell 1 through the drain port, the level of the admixture inside and outside the shell 1 gradually decreases, so that the buoyancy ring 504 is affected by its own buoyancy and gradually moves downward following the change of the water level (the buoyancy ring 504 always floats on the water surface due to its buoyancy), and the buoyancy ring 504 drives the circumferentially evenly distributed connecting rods 502 to move downward, and the connecting rods 502 drive the adjacent first scraper 501 and the adjacent second scraper 503 to move downward. At this time, the output shaft of the second electronically controlled motor 4 is controlled to rotate through the control panel. In the process of the rotation of the stirring rod 403, the stirring rod 403 drives the circumferentially evenly distributed sliding frame 5 to rotate, and the sliding frame 5 drives the adjacent first scraper 501 to rotate. The first scraper 501 drives the adjacent second scraper 503 to rotate through the adjacent connecting rod 502, so as to remove the undissolved chemical powder, by-products, precipitates or crystals attached to the inner wall of the shell 1. During the scraping process, if there are hard crystals in the shell 1, the crystals squeeze the first scraper 501 or the adjacent second scraper 503, so that the elastic sheet 6 is squeezed and deformed, and the first scraper 501 moves to a position away from the inner wall of the shell 1. The first scraper 501 drives the adjacent second scraper 503 to move through the adjacent connecting rod 502. The first scraper 501 and the adjacent second scraper 503 scrape the impurities on the inner wall of the shell 1 layer by layer to prevent the crystals from being too hard and causing the first scraper 501 or the adjacent second scraper 503 to break or be damaged. The upper first scraper 501 is located above the water surface, and the lower second scraper 503 is located below the water surface. When the second scraper 503 scrapes the impurities attached to the inner wall of the shell 1, the additive solution in the shell 1 flows and flushes its inner wall, thereby enhancing the cleaning force of the second scraper 503 on the inner wall of the shell 1.

[0049] After the existing admixtures are prepared, they need to be filled in batches. When the liquid level in the reactor is high, directly opening the discharge port of the reactor will result in a high pressure of the admixture solution and a large amount of admixture sprayed out. As the liquid level in the reactor decreases, the solution pressure in the reactor will gradually decrease, and the amount of admixture sprayed will decrease accordingly, resulting in constant changes in the filling position and filling amount of the admixture, thereby affecting the filling efficiency of the admixture.

[0050] Embodiment 3: Based on embodiment 2, Figure 1 and Figure 10-12As shown, it also includes a support frame 9, which is arranged below the shell 1, and the support frame 9 is rotatably connected to a feed tray 901 near the shell 1, and a collecting shell evenly distributed circumferentially is installed on the feed tray 901. The support frame 9 is fixedly connected to a third electrically controlled motor 902 electrically connected to the control panel, and the output shaft of the third electrically controlled motor 902 is fixedly connected to the feed tray 901. The lower part of the shell 1 is fixedly connected to and communicated with a collecting pipe embedded in its drain port, and the shell 1 is fixedly connected to a fourth electrically controlled motor 903 electrically connected to the control panel near its collecting pipe, and the output shaft of the fourth electrically controlled motor 903 The shaft is fixedly connected with a limit plate 904 which cooperates with the collection pipe on the housing 1 to block the collection pipe. The lower side of the housing 1 is fixedly connected with a diversion shell 905. The diversion shell 905 is connected with the collection pipe of the housing 1 through the diversion pipe. An electric control valve is installed on the diversion pipe. The electric control valve is electrically connected to the control panel. When the collection pipe is blocked by the limit plate 904, the electric control valve opens and blocks the diversion pipe to prevent the additive solution from flowing into the diversion pipe at this time. A first pressure plate 906 is sealed and slidably connected in the diversion shell 905. There are circumferentially evenly distributed fixedly connected between the first pressure plate 906 and the diversion shell 905. The elastic member evenly distributed in the circumference is used to prevent the first pressure plate 906 from tilting and being stressed when moving up and down, wherein the elastic member is a compression spring, and when the shell 1 is full of water, the water pressure in the shell 1 is greater than the elastic force of the elastic member, and after the water level in the shell 1 is reduced by half, the elastic force of the elastic member begins to be greater than the water pressure in the shell 1, and as the water level in the shell 1 decreases, the elastic force of the elastic member gradually becomes greater than the water pressure in the shell 1, and the lower sealing sliding connection in the shell 1 is provided with a second pressure plate 907, and a pressure chamber is provided between the lower side of the second pressure plate 907 and the shell 1, and the pressure chamber The shell 1 is filled with hydraulic oil. When the water in the shell 1 is full, the resistance of the second pressure plate 907 to move downward is less than the water pressure on its upper side. After the water in the shell 1 is reduced by half, the water pressure on the upper side of the second pressure plate 907 is less than the resistance to its downward movement. A hydraulic telescopic rod 908 connected to the pressure chamber is fixedly connected to the bottom of the shell 1. The telescopic end of the hydraulic telescopic rod 908 is squeezed and matched with the first pressure plate 906. When the telescopic end of the hydraulic telescopic rod 908 moves downward, the telescopic end of the hydraulic telescopic rod 908 squeezes the first pressure plate 906 to move downward, so that the elastic part of the first pressure plate 906 is compressed.

[0051] When the admixture preparation reaction is completed, the operator turns on the fourth electronically controlled motor 903 through the control panel, and the output shaft of the fourth electronically controlled motor 903 drives the limit plate 904 to rotate. When the limit plate 904 rotates until it loses contact with the collecting pipe, the admixture is discharged through the collecting pipe and falls into the collecting shell on the unloading tray 901 (before the admixture is discharged, the collecting shells evenly distributed in the circumferential direction are fixed on the unloading tray 901). At the same time, the fourth electronically controlled motor 903 is turned on through the control panel, and the output shaft of the fourth electronically controlled motor 903 drives the unloading tray 901 to rotate. The collecting shell on it is driven to rotate. When one collecting shell is aligned with the collecting pipe, the output shaft of the fourth electrically-controlled motor 903 stops rotating, and the additive is discharged into the collecting shell along the collecting pipe. When one collecting shell is full, the limit plate 904 rotates to align with the collecting pipe and seal it again. The output shaft of the fourth electrically-controlled motor 903 drives the discharge tray 901 to rotate, so that the second collecting shell is aligned with the collecting pipe, and then the output shaft of the fourth electrically-controlled motor 903 stops rotating, and the limit plate 904 rotates to lose the seal with the collecting pipe again. The above operation is repeated to collect the additive continuously.

[0052] In the process of collecting the admixture, initially the liquid level of the admixture inside and outside the shell 1 is high, and the liquid pressure on the upper side of the second pressure plate 907 is large. The second pressure plate 907 moves downward and squeezes the telescopic end of the hydraulic telescopic rod 908 through the hydraulic oil in the pressure chamber to extend, and the telescopic end of the hydraulic telescopic rod 908 drives the first pressure plate 906 to move downward, and the elastic part of the first pressure plate 906 contracts. At this time, the pressure of the admixture discharged from the collection pipeline is large and the flow rate is fast. A part of the admixture is diverted to the diversion shell 905 through the diversion pipeline, and a part of the admixture is temporarily stored on the upper side of the first pressure plate 906. When the liquid level of the admixture inside and outside the shell 1 drops, the second pressure plate The liquid pressure on the upper side of 907 decreases, the telescopic end of the second pressure plate 907 contracts, and the elastic part of the first pressure plate 906 gradually resets and drives it to move upward, so that the telescopic end of the hydraulic telescopic rod 908 is reset and the second pressure plate 907 is reset by squeezing the hydraulic oil. During the resetting of the first pressure plate 906, the additive squeezed on its upper side flows back to the collecting pipe through the shunt pipe, and then discharged into the collecting shell through the collecting pipe. After the liquid level of the additive inside and outside the shell 1 drops, the amount of the additive in the collecting shell is compensated to prevent the additive amounts in different collecting shells from being different when the liquid level of the additive inside and outside the shell 1 changes, thereby affecting the effect of subsequent use.

[0053] When the device needs to be stopped, the device is reset, and the third electronically controlled motor 902 and the fourth electronically controlled motor 903 are turned off, and then the device is cleaned for the next use.

[0054] Embodiment 4: Based on the embodiment 3, Figure 1-Figure 12As shown, a method for using a reactor for a high-performance concrete admixture is based on the above-mentioned reactor for a high-performance concrete admixture, and the specific steps are as follows:

[0055] Step 1: water is injected into the housing 1 through the water injector 1001, and the buoyancy ring 504 is affected by its own buoyancy and gradually moves upward following the position of the water flow, and then the chemical powder is placed between the grinding table 3 and the grinding shell 301, and the second electronically controlled motor 4 drives the rotating shaft 401 through the second gear set, and the rotating shaft 401 drives the grinding table 3 through the transmission belt, so that the grinding table 3 and the grinding shell 301 rotate relative to each other and grind the packaged materials, and then the chemical powder enters the storage chamber of the hollow shaft 1004;

[0056] Step 2: The output shaft of the first electronically controlled motor 1002 transmits the adjacent threaded rod 1003 through the first gear set, and the threaded rod 1003 rotates and drives the sliding plate 1007 to move up and down. With the movement of the sliding plate 1007, after the first blocking block 204 loses its blocking of the adjacent discharge port 1006 and the second blocking block 206 loses its blocking of the adjacent connecting holes on the partition plate 1005, the gas in the gas storage chamber of the hollow shaft 1004 enters the storage chamber along the connecting holes, and the gas in the hollow shaft 1004 sprays the chemical powder in its storage chamber into the housing 1 through the discharge port 1006 and the discharge holes of the sliding plate 1007;

[0057] Step 3: During the rotation of the rotating shaft 401, the rotating shaft 401 drives the rotating disk 402 through the second gear set and the gear ring, and the rotating disk 402 drives the stirring rod 403 to rotate, and the stirring rod 403 stirs the chemical powder and water in the housing 1;

[0058] Step 4: After the admixture preparation reaction is completed, the admixture is discharged through the collection pipe and falls into the collection shell on the discharge tray 901. The liquid level of the admixture in the shell 1 gradually decreases, and the buoyancy ring 504 drives the adjacent first scraper 501 and the adjacent second scraper 503 to move downward through the connecting rod 502, and cooperates with the deformation of the elastic sheet 6 to scrape off the impurities on the inner wall of the shell 1 layer by layer;

[0059] Step 5: During the process of collecting the admixture, the first pressure plate 906 and the second pressure plate 907 are moved to divert the admixture in the collection pipe when the liquid level of the admixture in the shell 1 is high, and to compensate the amount of the admixture in the collection shell after the liquid level of the admixture in the shell 1 drops;

[0060] Step 6: When the additive in the housing 1 is discharged and collected, if the device needs to be stopped, the device is reset and the power is turned off, and then the device is cleaned for the next use.
