Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pre-dissolving tanks for polycarboxylate superplasticizers, and particularly relates to a pre-dissolving tank for macromonomers of polycarboxylate superplasticizers. Background Technology
[0002] As a core component of high-performance concrete admixtures, polycarboxylate superplasticizers have their macromonomer pre-dissolution process directly affecting product quality and production efficiency. The pre-dissolution tank, as a key piece of equipment in this process, needs to achieve efficient filtration and stable sealing during the dissolution process.
[0003] For example, Chinese patent CN217490677U discloses a pre-dissolving tank for polycarboxylate superplasticizer macromonomers. The pre-dissolving tank has legs fixed to both ends of its bottom outer wall. A stirring component is installed inside the pre-dissolving tank, and a feeding assembly is located on the left end of its top outer wall. The feeding assembly includes a feeding tank, a crushing component, and a uniform feeding component. The bottom end of the feeding tank is fixedly connected to the left end of the top outer wall of the pre-dissolving tank via a bracket. Both ends of the crushing component are rotatably connected to the upper part of the front and rear inner walls of the feeding tank. As can be seen from the above, this invention avoids solid raw material agglomeration and uniformly transports the solid raw material into the pre-dissolving tank for pre-dissolving treatment, thereby achieving higher efficiency in dissolving polycarboxylate superplasticizers.
[0004] The aforementioned patent has the following problems:
[0005] This patented device has several drawbacks in use, such as: firstly, after prolonged use, the filter screen is easily clogged by solid particles, leading to increased filtration resistance and decreased filtrate flow, directly affecting pre-dissolution efficiency and product quality; secondly, the filter screen uses a fixed installation structure, requiring the disassembly of multiple tank components to replace the screen, which is cumbersome and time-consuming, increasing downtime maintenance costs; and thirdly, the existing pre-dissolution tank's sealing design is inadequate, making it prone to liquid leakage or external contaminant intrusion during stirring, affecting solution purity and potentially causing safety hazards. Therefore, we propose a pre-dissolution tank for polycarboxylate superplasticizer macromonomers. Utility Model Content
[0006] The purpose of this invention is to provide a pre-dissolving tank for polycarboxylate superplasticizer macromonomers to solve the problems mentioned in the background art.
[0007] In view of this, the present invention provides a pre-dissolution tank for polycarboxylate superplasticizer macromonomers, comprising:
[0008] A storage tank is provided, in which a stirring rod is rotatably installed. A motor is fixedly installed at the top of the storage tank, and the output end of the motor passes through the top of the storage tank and is coaxially connected to the stirring rod. A connecting pipe is fixedly installed at the bottom of the storage tank, and a through groove is opened in the connecting pipe. A slider is slidably installed in the through groove. The slider has two mounting slots, one of which is used to insert a filter element. A sealing gasket is fixedly installed at the top and bottom of the slider. Limiting grooves are opened on both sides of the slider. Limiting blocks are fixedly installed on the inner wall of the through groove and in both limiting grooves.
[0009] A fixing component, located inside the connecting tube, is used to fix the slider;
[0010] A feed pipe is fixedly installed on the top of the storage tank. A sealing cap is threaded onto the feed pipe, and a sealing gasket is fixedly installed on the top of the inner cavity of the sealing cap.
[0011] A limiting component is located at the top of the storage tank and is used to limit the sealing cap.
[0012] In this technical solution, when the filter element's filtration effect deteriorates over a long period, personnel can first insert a new filter element into another mounting slot from the bottom. Then, the slider can be released from its fixation by the fixing component. Personnel can push the slider to slide it within the through slot until the new filter element moves into the through slot. At this point, the inner wall of the through slot can limit the filter element, while the fixing component can fix the slider. The old filter element will move out to one side of the connecting pipe. Under the action of gravity, the old filter element will fall out of the mounting slot. With the sealing effect of the two sealing gaskets, it can be ensured that there is no water leakage between the through slot and the slider. At the same time, during the movement of the slider, the limiting groove will also slide on the limiting block. With the limiting effect of the limiting groove and the limiting block, the slider can be prevented from falling out of the through slot. This ensures that when the filter element fails, it is easy for personnel to replace the filter element, and the material discharge operation can still be carried out during the replacement process, ensuring that the normal material discharge of the through slot is not affected when replacing the filter element.
[0013] When the storage tank is full of polycarboxylate superplasticizer, the personnel can screw the sealing cap onto the feed pipe until the sealing gasket inside the sealing cap is against the top of the feed pipe. At this time, the sealing cap can seal the feed pipe. Then, the personnel can limit the sealing cap through the limiting component to ensure that the sealing cap will not rotate without the action of external force, thereby making the sealing performance of the feed pipe better and ensuring that there is no air leakage in the feed pipe.
[0014] In the above technical solution, the fixing component further includes:
[0015] A sliding groove is formed inside the connecting pipe and located below the slider. A sliding block is slidably installed inside the sliding groove. Two grooves are formed at the bottom of the slider. The top of the sliding block passes through the top of the sliding groove and extends into one of the grooves. A spring fixed to the bottom of the sliding block is fixedly installed at the bottom of the sliding block. One side of the sliding block passes through the sliding groove and extends to the outside.
[0016] In this technical solution, when the filter element's filtration effect deteriorates over time, the operator can first insert a new filter element into another mounting slot from the bottom. Then, press down on the sliding block. The downward movement of the sliding block compresses the spring, causing it to contract until the top of the sliding block moves out of the groove. At this point, the sliding block releases the slider, allowing the operator to push it, causing it to slide within the through groove until a new filter element moves into it. The inner wall of the through groove then limits the filter element's position. Under the spring's rebound force, the spring compresses the sliding block upwards until the top of the sliding block inserts into another groove. The moving block can fix the slider, and the old filter element will move to one side of the connecting pipe. At this time, under the action of gravity, the old filter element will fall out of the mounting groove. With the sealing effect of the two sealing gaskets, it can be ensured that there is no water leakage between the through groove and the slider. At the same time, the slider will also drive the limiting groove to slide on the limiting block during the movement. With the limiting groove and the limiting block limiting, the slider can be prevented from falling out of the through groove. This ensures that when the filter element fails, it is easy for personnel to replace the filter element. The material discharge operation can still be carried out during the replacement process, ensuring that the normal material discharge of the through groove is not affected when replacing the filter element.
[0017] In the above technical solution, the top end of the sliding block is further engaged with the groove.
[0018] In this technical solution, it is ensured that the top of the sliding block can be inserted into the groove.
[0019] In the above technical solution, the limiting component further includes:
[0020] A rectangular block is fixedly installed on the top of the storage tank and located on one side of the sealing cover. Several anti-slip strips are fixedly installed on the periphery of the sealing cover. A threaded rod is threaded onto the rectangular block. An extrusion plate is rotatably installed at one end of the threaded rod. A rubber pad is fixedly installed on one side of the extrusion plate.
[0021] In this technical solution, when the storage tank is filled with polycarboxylate superplasticizer, the operator can screw the sealing cap onto the feed pipe until the sealing gasket inside the sealing cap abuts against the top of the feed pipe. At this point, the sealing cap can seal the feed pipe. Then, the operator can rotate the threaded rod. Under the action of the thread, the rotation of the threaded rod will drive the extrusion plate to move. At the same time, one end of the threaded rod will rotate on the extrusion plate. Since the bottom of the extrusion plate abuts against the top of the storage tank, the rotation of the threaded rod will not drive the extrusion plate to rotate until one side of the rubber pad of the extrusion plate abuts against the periphery of the sealing cap. At this point, several anti-slip strips will compress the rubber pad and deform it, thereby limiting the sealing cap and ensuring that the sealing cap will not rotate without the action of external force. This improves the sealing performance of the feed pipe and ensures that there is no air leakage in the feed pipe.
[0022] In the above technical solution, further, the anti-slip strips are distributed in a ring at equal intervals, and the extrusion plate has an arc-shaped structure.
[0023] In this technical solution, the distribution of several anti-slip strips is ensured to be uniform, thereby guaranteeing the structural stability of the extruded plate.
[0024] In the above technical solution, a discharge pipe is further fixedly installed at the bottom of the connecting pipe, and a valve is rotatably installed inside the discharge pipe.
[0025] In this technical solution, when the valve is opened, the polycarboxylate superplasticizer will pass through the channel, filter element, and discharge pipe in sequence, and finally be discharged to the outside. The filter element can filter the polycarboxylate superplasticizer, removing impurities and bubbles generated during the pre-dissolution process.
[0026] In the above technical solution, the output shaft of the motor is rotatably connected to the storage tank, and the limiting block is slidably connected to the limiting groove.
[0027] In this technical solution, it is ensured that the output shaft of the motor can rotate normally inside the storage tank, and that the limit block can slide normally within the limit groove.
[0028] The beneficial effects of this utility model are:
[0029] 1. The pre-dissolving tank for the polycarboxylate superplasticizer macromonomer, through the installation groove, slider, fixing components, through groove, filter element, connecting pipe, limiting block and limiting groove, ensures that when the filter element fails, personnel can easily replace it, and the material discharge operation can still be carried out during the replacement process, ensuring that the normal material discharge of the through groove is not affected when replacing the filter element.
[0030] 2. The pre-dissolving tank for the polycarboxylate superplasticizer macromonomer, through the setting of a sealing cover, ensures that the sealing cover will not rotate without the action of external force through the cooperation of the sealing cover, the feed pipe, the sealing gasket, and the limiting component, thereby improving the sealing performance of the feed pipe and ensuring that there is no air leakage in the feed pipe.

[0044] Example 1:
[0045] Please see Figure 1 - Figure 6 As shown, this embodiment provides a pre-dissolution tank for polycarboxylate superplasticizer macromonomers, comprising:
[0046] Storage tank 1, with a stirring rod 2 rotatably installed inside storage tank 1, a motor 3 fixedly installed on the top of storage tank 1, the output end of motor 3 passing through the top of storage tank 1 and coaxially connected to stirring rod 2, a connecting pipe 23 fixedly installed on the bottom of storage tank 1, a through groove 8 opened in the connecting pipe 23, a slider 4 slidably installed in the through groove 8, two mounting grooves 5 opened in the slider 4, a filter element 6 inserted into one of the mounting grooves 5, a sealing gasket 7 fixedly installed on the top and bottom of slider 4, a limit groove 9 opened on both sides of slider 4, and a limit block 10 fixedly installed on the inner wall of through groove 8 and in the two limit grooves 9;
[0047] A fixing component is located inside the connecting tube 23 and is used to fix the slider 4.
[0048] Feed pipe 15 is fixedly installed on the top of storage tank 1. A sealing cap 16 is threaded onto the feed pipe 15. A sealing gasket 17 is fixedly installed on the top of the inner cavity of the sealing cap 16.
[0049] A limiting component is located at the top of the storage tank 1 and is used to limit the sealing cap 16.
[0050] When filter element 6 is used for an extended period, its filtration efficiency will decrease. In this case, a new filter element 6 can be inserted from the bottom into another mounting slot 5. Then, the slider 4 can be released from its fixed position using the fixing component. The slider 4 can be pushed, allowing it to slide within the through groove 8 until the new filter element 6 moves into it. At this point, the inner wall of the through groove 8 can limit the movement of the filter element 6, while the fixing component secures the slider 4. The old filter element 6 will then move to one side of the connecting pipe 23. Under the influence of gravity, the old filter element 6 will then... The slider 4 falls out of the mounting groove 5 and is sealed by the two sealing gaskets 7, ensuring that there is no water leakage between the through groove 8 and the slider 4. At the same time, the slider 4 will also drive the limiting groove 9 to slide on the limiting block 10 during the movement. Under the limiting effect of the limiting groove 9 and the limiting block 10, the slider 4 can be prevented from falling out of the through groove 8, ensuring that when the filter element 6 fails, it is easy for personnel to replace the filter element 6, and the material discharge operation can still be carried out during the replacement process, ensuring that the normal material discharge of the through groove 8 is not affected when replacing the filter element 6.
[0051] When storage tank 1 is filled with polycarboxylate superplasticizer, personnel can screw the sealing cap 16 onto the feed pipe 15 until the sealing gasket 17 inside the sealing cap 16 abuts against the top of the feed pipe 15. At this time, the sealing cap 16 can seal the feed pipe 15. Subsequently, personnel can limit the sealing cap 16 through the limiting component to ensure that the sealing cap 16 will not rotate without the action of external force, thereby making the sealing performance of the feed pipe 15 better and ensuring that there is no air leakage in the feed pipe 15.
[0052] Example 2:
[0053] This embodiment provides a pre-dissolution tank for polycarboxylate superplasticizer macromonomers. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the fixing components include:
[0054] The sliding groove 11 is opened inside the connecting pipe 23 and located below the slider 4. A sliding block 12 is slidably installed in the sliding groove 11. Two grooves 13 are opened at the bottom of the slider 4. The top of the sliding block 12 passes through the top of the sliding groove 11 and extends into one of the grooves 13. A spring 14 fixed to the bottom of the sliding groove 11 is fixedly installed at the bottom of the sliding block 12. One side of the sliding block 12 passes through the sliding groove 11 and extends to the outside.
[0055] When filter element 6 is used for an extended period, its filtration effect will deteriorate. In this case, a new filter element 6 can be inserted into another mounting slot 5 from the bottom. Then, the sliding block 12 is pressed down. The downward movement of the sliding block 12 compresses the spring 14, causing it to contract. When the top of the sliding block 12 moves out of the groove 13, the sliding block 12 releases its hold on the slider 4. The slider 4 can then be pushed, allowing it to slide within the through groove 8 until the new filter element 6 moves into it. At this point, the inner wall of the through groove 8 limits the filter element 6. Under the rebound force of the spring 14, the spring 14 compresses the sliding block 12, causing it to move upwards until the top of the sliding block 12 is inserted into another groove 13. When the sliding block 12 is in place, the slider 4 can be fixed, and the old filter element 6 will move to one side of the connecting pipe 23. At this time, under the action of gravity, the old filter element 6 will fall out of the mounting groove 5. Under the sealing effect of the two sealing gaskets 7, it can be ensured that there will be no water leakage between the through groove 8 and the slider 4. At the same time, during the movement of the slider 4, the limiting groove 9 will also slide on the limiting block 10. Under the limiting effect of the limiting groove 9 and the limiting block 10, the slider 4 can be prevented from falling out of the through groove 8, ensuring that when the filter element 6 fails, it is easy for personnel to replace the filter element 6, and the material discharge operation can still be carried out during the replacement process, ensuring that the normal material discharge of the through groove 8 will not be affected when replacing the filter element 6.
[0056] Example 3:
[0057] This embodiment provides a pre-dissolving tank for polycarboxylate superplasticizer macromonomers. In addition to the technical solutions of the above embodiments, it also has the following technical features: the top of the sliding block 12 is inserted into the groove 13.
[0058] Specifically, it is ensured that the top of the sliding block 12 can be inserted into the groove 13.
[0059] Example 4:
[0060] This embodiment provides a pre-dissolution tank for polycarboxylate superplasticizer macromonomers. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the limiting component includes:
[0061] A rectangular block 19 is fixedly installed on the top of the storage tank 1 and located on one side of the sealing cover 16. Several anti-slip strips 18 are fixedly installed on the periphery of the sealing cover 16. A threaded rod 20 is threadedly installed on the rectangular block 19. A pressing plate 21 is rotatably installed on one end of the threaded rod 20. A rubber pad 22 is fixedly installed on one side of the pressing plate 21.
[0062] When storage tank 1 is filled with polycarboxylate superplasticizer, personnel can screw the sealing cap 16 onto the feed pipe 15 until the sealing gasket 17 inside the sealing cap 16 abuts against the top of the feed pipe 15. At this time, the sealing cap 16 can seal the feed pipe 15. Then, personnel can rotate the threaded rod 20. Under the action of the thread, the rotation of the threaded rod 20 will drive the extrusion plate 21 to move. At the same time, one end of the threaded rod 20 will rotate on the extrusion plate 21. Since the bottom of the extrusion plate 21 abuts against the top of storage tank 1, the rotation of the threaded rod 20 will not drive the extrusion plate 21 to rotate until the rubber gasket 22 on one side of the extrusion plate 21 abuts against the periphery of the sealing cap 16. At this time, several anti-slip strips 18 will squeeze the rubber gasket 22 to deform, thereby limiting the sealing cap 16 and ensuring that the sealing cap 16 will not rotate without the action of external force. This makes the sealing performance of the feed pipe 15 better and ensures that the feed pipe 15 will not leak.
[0063] Example 5:
[0064] This embodiment provides a pre-dissolving tank for polycarboxylate superplasticizer macromonomers. In addition to the technical solutions of the above embodiments, it also has the following technical features: a plurality of anti-slip strips 18 are distributed in a ring at equal intervals, and the extrusion plate 21 has an arc-shaped structure.
[0065] In this process, it is ensured that the distribution of the anti-slip strips 18 is uniform, thereby ensuring the structural stability of the extrusion plate 21.
[0066] Example 6:
[0067] This embodiment provides a pre-dissolving tank for polycarboxylate superplasticizer macromonomers. In addition to the technical solutions of the above embodiments, it also has the following technical features: a discharge pipe 24 is fixedly installed at the bottom of the connecting pipe 23, and a valve is rotatably installed inside the discharge pipe 24.
[0068] When the valve is opened, the polycarboxylate superplasticizer will pass through the channel 8, the filter element 6, and the discharge pipe 24 in sequence, and finally be discharged to the outside. The filter element 6 can filter the polycarboxylate superplasticizer, removing impurities in the polycarboxylate superplasticizer and also removing the bubbles generated by the polycarboxylate superplasticizer during pre-dissolution.
[0069] Example 7:
[0070] This embodiment provides a pre-dissolving tank for polycarboxylate superplasticizer macromonomers. In addition to the technical solutions of the above embodiments, it also has the following technical features: the output shaft of the motor 3 is rotatably connected to the storage tank 1, and the limiting block 10 is slidably connected to the limiting groove 9.
[0071] This ensures that the output shaft of motor 3 can rotate normally within storage tank 1 and that the limit block 10 can slide normally within limit groove 9.
[0072] Working principle: During use, the operator can unscrew the sealing cap 16 from the feed pipe 15, and then pour the polycarboxylate superplasticizer into the storage tank 1 through the feed pipe 15. The operator can start the motor 3, and the output shaft of the motor 3 will drive the stirring rod 2 to rotate. The rotation of the stirring rod 2 can stir the polycarboxylate superplasticizer. When it is necessary to discharge the polycarboxylate superplasticizer from the storage tank 1, the operator can open the valve. The polycarboxylate superplasticizer will pass through the channel 8, the filter element 6 and the discharge pipe 24 in sequence, and finally be discharged to the outside. The filter element 6 can filter the polycarboxylate superplasticizer, removing impurities in the polycarboxylate superplasticizer and also removing the air bubbles generated during the pre-dissolution of the polycarboxylate superplasticizer.
[0073] When filter element 6 is used for a long time, its filtration effect will deteriorate. At this time, a new filter element 6 can be inserted into another mounting slot 5 from the bottom. Then, the sliding block 12 is pressed down. The downward movement of the sliding block 12 compresses the spring 14, causing it to contract until the top of the sliding block 12 moves out of the groove 13. At this point, the sliding block 12 can release the slider 4, allowing the operator to push the slider 4, causing it to slide within the through groove 8 until the new filter element 6 moves into the through groove 8. The inner wall of the through groove 8 then limits the filter element 6. Under the rebound force of the spring 14, the spring 14 will compress the sliding block 12 upwards until the top of the sliding block 12 is inserted into another groove 13. The sliding block 12 can fix the slider 4, and the old filter element 6 will move to one side of the connecting pipe 23. At this time, under the action of gravity, the old filter element 6 will fall out of the mounting groove 5. Under the sealing effect of the two sealing gaskets 7, it can be ensured that there is no water leakage between the through groove 8 and the slider 4. At the same time, the slider 4 will also drive the limiting groove 9 to slide on the limiting block 10 during the movement. Under the limiting effect of the limiting groove 9 and the limiting block 10, the slider 4 can be prevented from falling out of the through groove 8, ensuring that when the filter element 6 fails, it is easy for personnel to replace the filter element 6, and the material discharge operation can still be carried out during the replacement process, ensuring that the normal material discharge of the through groove 8 will not be affected when replacing the filter element 6.
[0074] When storage tank 1 is filled with polycarboxylate superplasticizer, personnel can screw the sealing cap 16 onto the feed pipe 15 until the sealing gasket 17 inside the sealing cap 16 abuts against the top of the feed pipe 15. At this time, the sealing cap 16 can seal the feed pipe 15. Then, personnel can rotate the threaded rod 20. Under the action of the thread, the rotation of the threaded rod 20 will drive the extrusion plate 21 to move. At the same time, one end of the threaded rod 20 will rotate on the extrusion plate 21. Since the bottom of the extrusion plate 21 abuts against the top of storage tank 1, the rotation of the threaded rod 20 will not drive the extrusion plate 21 to rotate until the rubber gasket 22 on one side of the extrusion plate 21 abuts against the periphery of the sealing cap 16. At this time, several anti-slip strips 18 will squeeze the rubber gasket 22 to deform, thereby limiting the sealing cap 16 and ensuring that the sealing cap 16 will not rotate without the action of external force. This makes the sealing performance of the feed pipe 15 better and ensures that the feed pipe 15 will not leak.
