Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of reactor technology, and more specifically, to a reactor for cement admixtures that allows for thorough discharge. Background Technology

[0002] Cement admixtures are a class of functional chemical additives added to cement concrete. They can effectively improve the workability of concrete, such as reducing water consumption and increasing fluidity for easier construction. They can also flexibly adjust the setting time, with early-strength admixtures helping concrete harden quickly and slow-setting admixtures suitable for high-temperature or long-distance transportation scenarios. At the same time, they can enhance the mechanical strength and durability of concrete.

[0003] Cement admixtures, as key functional materials in modern concrete preparation, rely on reactors for core processes such as mixing, reacting, and maturing various raw materials. The operating efficiency and material handling effect of the reactor directly affect the product quality and production continuity of the admixtures, playing a crucial role in large-scale production in the building materials industry. Currently, most cement admixture reactors used in the industry adopt traditional vertical structures, achieving uniform reaction of internal materials through stirring devices. After the reaction, the materials are usually discharged from the bottom or side of the reactor by gravity to complete subsequent transfer and processing. However, existing reactors often leave some material residue at the bottom or inner wall of the reactor during the discharge process, especially when the cement admixture material exhibits a certain viscosity due to its reaction characteristics. This residue problem is more pronounced. These residues not only waste raw materials and increase production costs but may also mix and contaminate with newly added raw materials in subsequent batches, affecting product quality stability. Furthermore, frequent cleaning of residues extends production intervals, reduces overall equipment operating efficiency, and makes it difficult to meet the demands of large-scale, continuous production. Therefore, improvements are needed. Utility Model Content

The outer surface of the stirring rod is movably connected to the inner surface of the hollow sleeve, and stirring blades are fixedly installed on the outer surface of the stirring rod.

[0009] As a preferred embodiment of this utility model, a circular frame is fixedly installed at the bottom of the reactor body, and a circular plate is movably fitted inside the circular frame.

[0010] As a preferred embodiment of this utility model, a discharge pipe is fixedly sleeved inside the circular plate, and a fixing block located below the circular frame is fixedly sleeved on the outer surface of the discharge pipe.

[0011] As a preferred embodiment of this utility model, a limiting frame is fixedly connected to the bottom of the circular frame, and limiting blocks are movably installed inside both the front and rear ends of the limiting frame. The outer surface of the limiting block is fixedly connected to the outer surface of the fixed block.

[0012] As a preferred embodiment of this utility model, springs are fixedly connected to both the left and right sides of the fixing block, and the other end of the springs is fixedly connected to the inner surface of the limiting frame.

[0013] As a preferred embodiment of this utility model, a round rod is fixedly connected to the right side of the fixing block. The right end of the round rod passes through the limiting frame and extends to the right side of the limiting frame, and is movably sleeved with the inner wall of the limiting frame. A movable plate is fixedly connected to the right end of the round rod.

[0014] As a preferred embodiment of this utility model, a power motor is fixedly installed on the outer surface of the support frame, and a round shaft is fixedly connected to the other end of the output shaft of the power motor. A rotating block is fixedly sleeved on the outer surface of the round shaft, and the outer surface of the rotating block is movably connected to the outer surface of the movable plate.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, by setting up a hollow sleeve, a high-pressure nozzle, a high-pressure air pump, and a drive motor, when some cement additives remain on the inner surface of the reactor body after the cement additives inside the reactor body are discharged, the high-pressure air pump is started to deliver high-pressure gas into the hollow sleeve through a connecting hose, and then sprayed out through a fixed pipe from the high-pressure nozzle, thereby cleaning the cement additives adhering to the inner surface of the reactor body. Furthermore, by starting the drive motor, the hollow sleeve can swing back and forth slightly, thereby swinging the high-pressure nozzle, so that the high-pressure airflow sprayed by the high-pressure nozzle can cover the inner surface of the reactor body in all directions, thereby completely discharging the cement additives.

[0016] 2. In this disclosure, by setting up a discharge pipe, a round rod, a power motor and a rotating block, during the discharge process, by starting the power motor, the round rod drives the rotating block to rotate, which in turn causes the rotating block to continuously squeeze and push the movable plate to move, thereby causing the movable plate to drive the fixed block and the discharge pipe to move through the round rod. As the rotating block continues to rotate, the discharge pipe will vibrate, thereby allowing the cement admixture inside the discharge pipe to be discharged more thoroughly.

[0026] like Figures 1 to 6 As shown, this invention illustrates a cement admixture reactor with thorough discharge according to an embodiment of the present disclosure. The reactor includes a reactor body 1, a support frame 2 fixedly fitted onto the outer surface of the reactor body 1, a hollow sleeve 3 movably fitted inside the top of the reactor body 1, a fixed pipe 4 fixedly installed at the bottom of the outer surface of the hollow sleeve 3, located at the top of the inner cavity of the reactor body 1, a high-pressure nozzle 5 fixedly connected to the bottom end of the fixed pipe 4, a high-pressure air pump 6 fixedly installed on the right side of the top of the reactor body 1, a connecting hose 7 fixedly connected to the left end of the high-pressure air pump 6, the left end of the connecting hose 7 fixedly connected to the right side of the hollow sleeve 3, a drive motor 8 fixedly installed on the left side of the top of the reactor body 1, a rotating shaft 9 fixedly connected to the other end of the output shaft of the drive motor 8, a disc 10 fixedly fitted onto the outer surface of the rotating shaft 9, a round block 11 fixedly fitted inside the left end of the disc 10, a connecting rod 12 fixedly installed on the left side of the hollow sleeve 3, located at the top of the reactor body 1, the inner surface of the connecting rod 12 movably connected to the outer surface of the round block 11.

[0027] After the high-pressure air pump 6 is started, it will draw in outside air and deliver high-pressure gas into the interior of the hollow sleeve 3 through the connecting hose 7. Then, it will be sprayed out through the fixed pipe 4 and the high-pressure nozzle 5. There are eight fixed pipes 4 and eight high-pressure nozzles 5. The eight fixed pipes 4 and the high-pressure nozzles 5 are evenly distributed along the outer surface of the hollow sleeve 3. When the hollow sleeve 3 rotates back and forth slightly, it will cause the fixed pipes 4 and the high-pressure nozzles 5 to rotate back and forth slightly, so that the high-pressure gas sprayed by the high-pressure nozzles 5 can completely cover the inner surface of the reactor body 1.

[0028] In some examples, a feed pipe 13 is fixedly installed on the top left side of the reactor body 1, and a sealing cap 14 is threaded onto the top of the outer surface of the feed pipe 13.

[0029] The operator can unseal the feed pipe 13 by rotating the sealing cap 14, and then feed materials into the reactor body 1 through the feed pipe 13.

[0030] In some examples, a mounting bracket 15 is fixedly installed on the top of the reactor body 1, and a stirring motor 16 is fixedly installed on the top of the inner surface of the mounting bracket 15.

[0031] By setting up the mounting bracket 15, the mounting bracket 15 can support and install the stirring motor 16.

[0032] In some examples, the other end of the output shaft of the stirring motor 16 is fixedly connected to a stirring rod 17, the outer surface of the stirring rod 17 is movably connected to the inner surface of the hollow sleeve 3, and a stirring blade 18 is fixedly installed on the outer surface of the stirring rod 17.

[0033] When the stirring motor 16 is started, the stirring rod 17 will drive the stirring blade 18 to rotate, thereby stirring and mixing the cement additives inside the reactor body 1.

[0034] In some examples, a circular frame 19 is fixedly installed at the bottom of the reactor body 1, and a circular plate 20 is movably fitted inside the circular frame 19.

[0035] The inner surface of the circular frame 19 is smooth, which allows the circular plate 20 to move more smoothly inside the circular frame 19.

[0036] In some examples, a discharge pipe 21 is fixedly fitted inside the circular plate 20, and a fixing block 22 located below the circular frame 19 is fixedly fitted on the outer surface of the discharge pipe 21.

[0037] The fixed block 22 is rectangular in shape. When the fixed block 22 moves, it will cause the discharge pipe 21 to move.

[0038] In some examples, the bottom of the circular frame 19 is fixedly connected to a limiting frame 23, and limiting blocks 24 are movably installed inside both the front and rear ends of the limiting frame 23. The outer surface of the limiting block 24 is fixedly connected to the outer surface of the fixing block 22.

[0039] The design of the limiting frame 23 enables the limiting frame 23 to limit the fixed block 22 through the limiting block 24, so that the fixed block 22 can only move left and right inside the limiting frame 23.

[0040] In some examples, springs 25 are fixedly connected to both the left and right sides of the fixing block 22, and the other end of the spring 25 is fixedly connected to the inner surface of the limiting frame 23.

[0041] After being compressed and stretched, the spring 25 will cause the fixed block 22 to move under the elastic recovery action, thereby causing the feed tube 21 to move.

[0042] In some examples, a round rod 26 is fixedly connected to the right side of the fixed block 22. The right end of the round rod 26 passes through the limiting frame 23 and extends to the right side of the limiting frame 23 and is movably sleeved with the inner wall of the limiting frame 23. A movable plate 27 is fixedly connected to the right end of the round rod 26.

[0043] When the movable plate 27 moves, it will drive the fixed block 22 to move via the round rod 26.

[0044] In some examples, a power motor 28 is fixedly mounted on the outer surface of the support frame 2, and a round shaft 29 is fixedly connected to the other end of the output shaft of the power motor 28. A rotating block 30 is fixedly sleeved on the outer surface of the round shaft 29, and the outer surface of the rotating block 30 is movably connected to the outer surface of the movable plate 27.

[0045] The rotating block 30 is elliptical in shape. When the rotating block 30 rotates continuously, it will continuously squeeze and push the movable plate 27, thereby causing the movable plate 27 to vibrate.

[0046] Working principle and usage process of this utility model: When discharging the cement admixture inside the reactor body 1, the high-pressure air pump 6 can be started to deliver high-pressure air into the hollow sleeve 3 and spray it out through the fixed pipe 4 and high-pressure nozzle 5. This allows the high-pressure nozzle 5 to clean the admixture on the inner surface of the reactor body 1, causing the cement admixture to fall off and be discharged through the discharge pipe 21. During the cleaning process, the drive motor 8 can be started to rotate the rotating shaft 9 and drive the disc 10 to rotate. This causes the disc 11 to squeeze and push the inner surface of the connecting rod 12, causing the connecting rod 12 to drive the hollow sleeve 3 to rotate slightly. This, in turn, causes the high-pressure nozzle 5 to rotate slightly, allowing the high-pressure gas sprayed from the high-pressure nozzle 5 to more thoroughly clean the inner surface of the reactor body 1, thus making the discharge of the cement admixture more complete.

[0047] When the operator discharges the cement admixture inside the reactor body 1, the power motor 28 is started, causing the round shaft 29 to drive the rotating block 30 to rotate. This causes the rotating block 30 to continuously squeeze and push the outer surface of the movable plate 27, which in turn causes the movable plate 27 to move the discharge pipe 21 via the round rod 26. As the rotating block 30 continues to rotate, the discharge pipe 21 will be moved continuously through the movable plate 27 and the round rod 26. The spring 25 will then reset the fixed block 22 and the discharge pipe 21 under the elastic recovery action. This process repeats, causing the discharge pipe 21 to vibrate, thus ensuring that the cement admixture discharged through the discharge pipe 21 is discharged more thoroughly.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
