Description

Technical Field

[0001] The invention relates to the technical field of preparing polycarboxylate water reducer, in particular to polycarboxylate water reducer powder production equipment. Background Art

[0002] Polycarboxylate water-reducing agent powder is a high-efficiency water-reducing agent commonly used in concrete engineering. It is used in construction engineering, roads and bridges and other fields, and can effectively improve the fluidity of concrete.

[0003] The patent with patent announcement number CN117225354B relates to a reactor and preparation method for producing polycarboxylate water reducer, and relates to the technical field of preparing polycarboxylate water reducer, comprising a reaction barrel, the side wall of the reaction barrel is connected to an air outlet pipe, and the upper end surface of the reaction barrel is fixedly connected to a drive motor. The reactor for producing polycarboxylate water reducer solves the problem that in the process of making polycarboxylate water reducer in the existing polycarboxylate water reducer reactor, a large amount of foam will gradually be generated by the reaction between materials, which is easy to cause a large number of bubble holes to appear in the polycarboxylate water reducer after the production, thereby reducing the water reduction rate and cohesiveness of the water reducer, and the traditional reactor cannot evenly sprinkle the defoamer after the raw materials are stirred and mixed. In the synthesis process of the water reducer, because the chemical substances react violently with each other, organic acid waste gas is usually generated due to high-temperature stirring. If it is directly discharged into the air, it will cause the staff to inhale harmful gases, thereby posing a safety hazard.

[0004] The above patent solves the problem that a large amount of foam will gradually be generated during the production of polycarboxylic acid water-reducing agent due to the reaction between materials, thereby effectively improving the water reduction rate and cohesiveness of the water-reducing agent. However, during the mixing and stirring process, agglomeration will occur when the powdered raw materials come into contact with the liquid. These agglomerates usually adhere to dead corners that are difficult for the agitator to reach, resulting in uneven mixing, which not only affects the overall quality of the polycarboxylic acid water-reducing agent, but also leads to a reduction in production efficiency.

[0014] The present invention provides a polycarboxylate water-reducing agent powder production device, which has the following beneficial effects: (1) In the polycarboxylic acid water-reducing agent powder production equipment, the cylindrical rod rotates under the influence of friction. The cylindrical rod stirs the raw materials while rotating. The cylindrical rod stirs the dead corner area inside the reactor, effectively preventing the raw materials from excessively adhering to the inner wall of the reactor, thereby ensuring the production quality of the polycarboxylic acid water-reducing agent powder. At the same time, the cylindrical rod applies pressure to the agglomerates under the action of thrust, so that the cylindrical rod crushes or disperses the agglomerates.

[0015] (2) In the polycarboxylic acid water-reducing agent powder production equipment, when the material distribution plate moves up and down reciprocatingly, the raw materials received by the material distribution plate are dispersed due to the repeated movement, and the material distribution plate is driven to rotate by the sleeve, so that the material distribution plate can evenly spread the defoaming agent into the mixed raw materials. The lifting frame drives the material distribution plate to move up and down reciprocatingly, thereby increasing the speed at which the raw materials flow downward from the circular hole. At the same time, the inclined surface of the scraper scrapes off the accumulated raw materials, so that the accumulated raw materials are separated from the circular hole. By arranging the scraper to contact the circular hole, the raw materials can be effectively prevented from accumulating at the circular hole, thereby avoiding shutdown or production delay caused by blockage during the reaction process.

[0016] (3) In the polycarboxylic acid water-reducing agent powder production equipment, the fixed rod is in intermittent contact with multiple elastic sheets to generate continuous vibration. The continuous vibration transmitted by the blocking rod is used to reduce the possibility of the lifting frame being stuck or jammed during movement, thereby effectively improving the smoothness of the movement of the lifting frame. At the same time, the elastic sheet in deformation exerts additional resistance on the fixed rod. The intermittent resistance exerted by the intermittent contact between the elastic sheet and the fixed rod effectively slows down the speed of the telescopic rod moving downward, thereby preventing the rubber sheet from pushing the lifting frame to move downward quickly and causing a collision.

[0021] Abutment plates 14 are installed on the upper and lower sides of the sliding plate 10, and a hole groove is opened on the surface of the support plate 15. The circumferential surface of the cylindrical rod 12 contacts the inner wall of the hole groove, and the circumferential surface of the abutment plate 14 contacts the inner wall of the hole groove. By setting the support plate 15 to provide support force for the cylindrical rod 12 and the abutment plate 14, it helps to improve the stability of the overall movement.

[0022] An arc groove is provided on one side of the abutment plate 14 close to the cylindrical rod 12, and the arc groove contacts the circumferential surface of the cylindrical rod 12. A spherical surface is provided on the top of the round block 13, which allows the cylindrical rod 12 to automatically adjust its position when encountering a lump to avoid obstruction of its own movement, and then apply stable pressure to break up the agglomerate, which helps to improve the uniformity of the reaction process.

[0023] When the present embodiment is working, a variety of raw materials are poured into the interior of the reactor 1 from the feed pipe 3 in sequence, and the servo motor 5 is started. The output end of the servo motor 5 drives the rotating rod 6 to rotate, and the rotating rod 6 rotates to drive the connecting rod 7 to rotate, and the connecting rod 7 rotates to drive the stirring blade 8 to move, and the stirring blade 8 moves to stir the raw materials inside the reactor 1. At the same time, the connecting rod 7 rotates to drive the carrying plate 9 to move, and the carrying plate 9 moves to drive the sliding plate 10 to move, and the sliding plate 10 moves to drive the cylindrical rod 12 to move, and the cylindrical rod 12 moves to drive the round block 13 to move, and the cylindrical rod 12 moves to drive the raw materials adhered to the inner wall of the reactor 1 to move, and at the same time, the circumferential surface of the cylindrical rod 12 is produced by the inner wall of the reactor 1 during the movement. Friction is generated, and the cylindrical rod 12 rotates under the influence of the friction. The cylindrical rod 12 stirs the raw materials near the inner wall area of ​​the reactor 1 when rotating. When there is raw material adhering to the circumferential surface of the cylindrical rod 12, the rotation of the cylindrical rod 12 drives the adhering raw material to move. The raw material contacts the abutment plate 14 during movement, and the abutment plate 14 blocks the adhering raw material, so that the cylindrical rod 12 continues to rotate and separates the adhering raw material. During the stirring process, the defoaming agent is poured into the interior of the reactor 1 from the water inlet pipe 2, and the defoaming agent flows downward into the mixed raw material. The dead corner area inside the reactor 1 is stirred by the cylindrical rod 12, which effectively prevents the raw material from excessively adhering to the inner wall of the reactor 1, thereby ensuring the production of the polycarboxylic acid water-reducing agent powder. In order to improve the production quality, when the raw materials adhering to the inner wall of the reactor 1 produce lumps, the circumferential surface of the cylindrical rod 12 contacts the lumps during rotation, and the lumps exert resistance on the cylindrical rod 12. The cylindrical rod 12 moves toward the connecting rod 7 under the influence of the resistance. The movement of the cylindrical rod 12 drives the sliding plate 10 to move toward the connecting rod 7. The movement of the sliding plate 10 drives the abutment plate 14 to move toward the connecting rod 7. When the cylindrical rod 12 and the abutment plate 14 move, the support plate 15 provides support for the cylindrical rod 12 and the abutment plate 14 through the hole groove. At the same time, the sliding plate 10 squeezes the No. 1 spring 11 during movement. The No. 1 spring 11 is squeezed and deformed. The deformed No. 1 spring 11 exerts a reaction force on the sliding plate 10. The sliding plate 10 Affected by the reaction force, a thrust is applied to the cylindrical rod 12, and the cylindrical rod 12 applies pressure to the agglomerates under the action of the thrust, so that the cylindrical rod 12 crushes or disperses the agglomerates. After the cylindrical rod 12 is separated from the agglomerates, the deformed spring 11 recovers and drives the sliding plate 10 to move away from the connecting rod 7. The movement of the sliding plate 10 drives the cylindrical rod 12 to move away from the connecting rod 7. The circumferential surface of the cylindrical rod 12 resumes contact with the inner wall of the reactor 1 during the movement, so that the cylindrical rod 12 continues to rotate. When encountering agglomerates, the cylindrical rod 12 automatically adjusts its position to avoid obstruction of its own movement, and then applies stable pressure to crush the agglomerates, which helps to improve the uniformity of the reaction process.

[0027] A spiral spring is arranged between the rotating shaft 176 and the fixed frame 171, and the elastic sheet 177 is arranged to be arc-shaped. The inner concave surface of the elastic sheet 177 contacts the circumferential surface of the blocking rod 178. By setting the shape of the elastic sheet 177 to be arc-shaped, it is ensured that when the elastic sheet 177 bends downward, it can be quickly separated from the fixed rod 175, which helps to improve the stability of the movement.

The moving scraper 167 moves synchronously, and the scraper 167 keeps stable contact with the top of the material distribution plate 163 during the movement. When the raw material accumulates at the circular hole, the flow speed of the raw material is affected. At the same time, the material distribution plate 163 rotates to drive the raw material to move. When the raw material contacts the inclined surface of the scraper 167 during the movement, the inclined surface of the scraper 167 scrapes off the accumulated raw material, so that the accumulated raw material is separated from the circular hole. By setting the scraper 167 to contact the circular hole, the raw material can be effectively prevented from accumulating at the circular hole, thereby avoiding shutdown or production delay caused by blockage during the reaction process, which helps to reduce the frequency of maintenance; When the lifting frame 165 moves upward, the lifting frame 165 moves to drive the rubber sheet 174 to move upward, and the rubber sheet 174 moves to drive the telescopic rod 172 to move upward.

The blocking rod 178 transmits the vibration generated by the collision to the lifting frame 1 65, the lifting frame 165 is affected by the vibration and moves more smoothly. The continuous vibration transmitted by the blocking rod 178 effectively improves the smoothness of the movement of the lifting frame 165 and reduces the jamming or jamming of the lifting frame 165 during movement. When the lifting frame 165 moves downward, the supporting force exerted by the lifting frame 165 on the rubber sheet 174 gradually decreases, so that the deformed No. 3 spring 173 recovers and drives the telescopic rod 172 to move downward. The movement of the telescopic rod 172 drives the rubber sheet 174 to move downward. At the same time, the movement of the telescopic rod 172 drives the fixed rod 175 to move downward. The circumferential surface of the fixed rod 175 is During the movement, the fixed rod 175 contacts the second arc surface of the elastic sheet 177, and the fixed rod 175 moves to squeeze the elastic sheet 177. The elastic sheet 177 is squeezed and bent downward. The deformed elastic sheet 177 exerts additional resistance on the fixed rod 175 under the action of its own elasticity. The downward movement speed of the fixed rod 175 is slowed down by the influence of the resistance, resulting in the downward movement speed of the telescopic rod 172 being controlled. The intermittent resistance is exerted by the intermittent contact between the elastic sheet 177 and the fixed rod 175, which effectively slows down the downward movement speed of the telescopic rod 172, and avoids the rubber sheet 174 pushing the lifting frame 165 to move downward quickly and cause a collision.
