Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent production technology, specifically a grinding and screening machine for water-reducing agent production. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining the slump of the concrete. Most are anionic surfactants, including lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. When added to concrete mixes, they disperse cement particles, improve workability, reduce water usage per unit area, and improve the fluidity of the concrete mix; or reduce cement usage per unit area, thus saving cement.

[0003] According to Chinese patent CN216704561U, a grinding and screening machine for the production of water-reducing agents is proposed. By fixing the base of the annular grinding bowl assembly to the bottom of the grinding box, the entire annular grinding bowl is supported. More specifically, a power motor is set at the upper end of the base, and a rotating base is connected to the output shaft of the power motor. A grinding main shaft is fixed at the upper end of the rotating base, and the annular grinding bowl is fixedly set on the upper end face of the grinding main shaft. This achieves rotation control of the annular grinding bowl. With the combination of the rotating grinding disc, the annular grinding bowl with rotation function achieves a more thorough and effective grinding process.

[0004] There are still some shortcomings in the existing technology. In the process of grinding water-reducing agents by grinding discs, a large amount of water-reducing agents need to be ground at the same time. During the grinding process, some water-reducing agents are prone to accumulate inside the grinding bowl, which makes the grinding effect worse and affects the grinding efficiency of water-reducing agents. To address this, we propose a grinding and screening machine for the production of water-reducing agents. Utility Model Content

[0005] The purpose of this invention is to provide a grinding and screening machine for the production of water-reducing agents, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding and screening machine for the production of water-reducing agents, including a mounting plate; The vibration assembly is disposed above the mounting plate. The vibration assembly includes a fixed base fixedly connected to the back of the mounting plate. A reversible motor is fixedly connected to the top inner wall of the fixed base. An output shaft is fixedly connected to the output end of the reversible motor. An incomplete gear is fixedly connected to the outer wall of the other end of the output shaft. A rectangular gear ring meshes with the outer wall of the incomplete gear. Limiting rods are fixedly connected to the outer walls of both sides of the rectangular gear ring. A limiting ring is slidably connected to the outer wall of the limiting rod. A fixing rod is fixedly connected to the bottom of the limiting ring. The bottom of the fixing rod is fixedly connected to the top of the mounting plate. An L-shaped plate is fixedly connected to the other end of the limiting rod. A push rod is fixedly connected to the bottom side wall of the L-shaped plate. A push plate is fixedly connected to the other end of the push rod. A sliding groove is formed inside the mounting plate. A crossbar is fixedly connected to the inner wall of the sliding groove. A slider is slidably connected to the outer wall of the crossbar. Springs are fixedly connected to both sides of the bottom outer wall of the slider. The other end of the springs is fixedly connected to the inner wall of the sliding groove. A bearing frame is fixedly connected to the top of the slider. The bearing frame is located on the side of the push plate.

[0007] Preferably, the top of the mounting plate is further provided with a grinding assembly, which includes an L-shaped fixing plate fixedly connected to the top of the front of the mounting plate. An electric push rod is fixedly connected to the top inner wall of the L-shaped fixing plate. A fixing frame is fixedly connected to the output end of the electric push rod. A drive motor is fixedly connected to the top inner wall of the fixing frame. A rotating shaft is fixedly connected to the output end of the drive motor. A grinding disc is fixedly connected to the other end of the rotating shaft. The grinding disc is located inside a support frame. A screening plate is fixedly connected to the inner wall of the support frame. A discharge pipe is connected to the bottom of the support frame. A solenoid valve is fixedly connected to the outer bottom wall of the discharge pipe. A collection frame is provided below the discharge pipe. The bottom of the collection frame is connected to the mounting plate. The top sliding connection, through the setting of the grinding component, allows the operator to place the water-reducing agent on top of the screening plate during the grinding process. Then, by activating the electric push rod, the operator extends the rod and pushes the fixed frame downwards, bringing the bottom of the grinding disc into contact with the surface of the water-reducing agent. Subsequently, by activating the drive motor, the rotating shaft rotates, causing the grinding disc to rotate and grind the water-reducing agent. The ground water-reducing agent is then screened through the screening plate. After screening, the operator activates the solenoid valve, causing the screened water-reducing agent to be discharged through the discharge pipe into the collection frame for collection.

[0008] Preferably, the bottom of the mounting plate is fixedly connected with four support legs. The four support legs are equidistantly fixedly connected to the bottom of the four corners of the mounting plate. By setting four support legs at the bottom of the mounting plate, stable support for the mounting plate can be achieved.

[0009] Preferably, there are two push plates, which are located on the outside of the two sides of the support frame. By setting two push plates on the two sides of the support frame, when the push plates squeeze the support frame, the water-reducing agent inside the support frame will vibrate and disperse, thus avoiding the accumulation of water-reducing agent and affecting the grinding effect.

[0010] Preferably, the outer wall of the limiting rod is adapted to the inner wall of the limiting ring, and one end of the limiting rod is fixedly connected to the outer wall of the rectangular toothed ring. The limiting rod and the limiting ring can facilitate the limiting of the rectangular toothed ring, allowing the rectangular toothed ring to move horizontally left and right.

[0011] Preferably, the grinding disc is located above the sieve plate.

[0012] This utility model provides a grinding and screening machine for the production of water-reducing agents. This grinding and screening machine for water-reducing agent production has the following beneficial effects: (1) This grinding and screening machine for water-reducing agent production, by setting a vibration component, requires the bearing frame to vibrate during the grinding process of the water-reducing agent inside the bearing frame to prevent the water-reducing agent from accumulating inside the bearing frame during grinding. At this time, the operator turns on the forward and reverse motor to cause the output shaft to rotate. During the rotation of the output shaft, the incomplete gear will rotate. The rotation of the incomplete gear will mesh with the inner wall of the rectangular gear ring. Under the limitation of the rectangular gear ring by the limit rod and the limit ring, the rectangular gear ring will move left and right. During the movement of the rectangular gear ring, it will be driven by... The limiting rod drives the L-shaped plate and the push rod to move. During the movement of the push rod, the push plate will move. After the push plate moves, it will squeeze the bearing frame. After being squeezed by the push plate, the bearing frame will move along the inside of the slide groove through the slider. After the slider moves, it will move along the outer wall of the crossbar and squeeze the spring, causing the spring to compress. When the push plate stops squeezing the bearing frame, the slider will return to its original position under the reaction of the spring, causing the bearing frame to return to its original position. This causes the bearing frame to vibrate during the grinding of the water-reducing agent, preventing the water-reducing agent from accumulating inside the bearing frame and affecting the grinding effect. (2) The grinding and screening machine for the production of water-reducing agent is equipped with a grinding component. When the water-reducing agent needs to be ground, the operator places the water-reducing agent on the top of the screening plate. Then, by turning on the electric push rod, the electric push rod is extended and the fixed frame is moved downward so that the bottom of the grinding disc contacts the surface of the water-reducing agent. Then, by turning on the drive motor, the rotating shaft is rotated. During the rotation of the rotating shaft, the grinding disc is rotated, so that the grinding disc grinds the water-reducing agent. The ground water-reducing agent is screened through the screening plate. After the water-reducing agent is screened, the operator turns on the solenoid valve to discharge the screened water-reducing agent into the inside of the collection frame through the discharge pipe. The water-reducing agent is collected through the collection frame. Attached Figure Description

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0017] Example 1 A grinding and screening machine for the production of water-reducing agents includes a mounting plate 1; The vibration assembly 31 is mounted on the mounting plate 1. The vibration assembly 31 includes a fixed base 311 fixedly connected to the back of the mounting plate 1. A reversible motor 312 is fixedly connected to the top inner wall of the fixed base 311. An output shaft 313 is fixedly connected to the output end of the reversible motor 312. An incomplete gear 314 is fixedly connected to the outer wall of the other end of the output shaft 313. A rectangular gear ring 315 meshes with the outer wall of the incomplete gear 314. Limiting rods 316 are fixedly connected to the outer walls of both sides of the rectangular gear ring 315. A limiting ring 317 is slidably connected to the outer wall of the limiting rod 316. A fixing rod 318 is fixedly connected to the bottom of the limiting ring 317. The bottom of the fixing rod 318 is fixedly connected to the top of the mounting plate 1. The other end of the limiting rod 316 is fixedly connected to the top of the mounting plate 1. An L-shaped plate 319 is fixedly connected to the mounting plate 1. A push rod 3110 is fixedly connected to the bottom side wall of the L-shaped plate 319. A push plate 3111 is fixedly connected to the other end of the push rod 3110. A groove 3112 is provided inside the mounting plate 1. A crossbar 3113 is fixedly connected to the inner wall of the groove 3112. A slider 3114 is slidably connected to the outer wall of the crossbar 3113. Springs 3115 are fixedly connected to both sides of the bottom outer wall of the slider 3114. The other end of the springs 3115 is fixedly connected to the inner wall of the groove 3112. A bearing frame 3116 is fixedly connected to the top of the slider 3114. The bearing frame 3116 is located on the side of the push plate 3111. By setting a vibration component 31, when the water-reducing agent is being ground inside the bearing frame 3116, in order to... To prevent the water-reducing agent from accumulating inside the bearing frame 3116 during grinding, the bearing frame 3116 needs to be vibrated. At this time, the operator turns on the forward / reverse motor 312, causing the output shaft 313 to rotate. During the rotation of the output shaft 313, the incomplete gear 314 rotates. The incomplete gear 314 meshes with the inner wall of the rectangular gear ring 315. Limiting the rectangular gear ring 315 via the limiting rod 316 and the limiting ring 317, the rectangular gear ring 315 moves left and right. During this movement, the limiting rod 316 drives the L-shaped plate 319 and the push rod 3110 to move. The movement of the push rod 3110 then drives the push plate 3111... The push plate 3111 moves and then presses the support frame 3116. After being pressed by the push plate 3111, the support frame 3116 moves along the inside of the slide groove 3112 via the slider 3114. After moving, the slider 3114 moves along the outer wall of the crossbar 3113 and presses the spring 3115, causing the spring 3115 to compress. When the push plate 3111 stops pressing the support frame 3116, the slider 3114 will reset under the reaction of the spring 3115, causing the support frame 3116 to reset. This causes the support frame 3116 to vibrate during the grinding of the water-reducing agent, preventing the water-reducing agent from accumulating inside the support frame 3116 and affecting the grinding effect. The bottom of the mounting plate 1 is fixedly connected with four support legs 2. The four support legs 2 are fixedly connected at equal intervals at the bottom of the four corners of the mounting plate 1. By setting four support legs 2 at the bottom of the mounting plate 1, stable support for the mounting plate 1 can be achieved. There are two push plates 3111. The two push plates 3111 are located on the outside of the two sides of the support frame 3116. By setting two push plates 3111 on the two sides of the support frame 3116, when the push plates 3111 squeeze the support frame 3116, the water-reducing agent inside the support frame 3116 will vibrate and disperse, thus avoiding the accumulation of water-reducing agent and affecting the grinding effect. The outer wall of the limiting rod 316 is adapted to the inner wall of the limiting ring 317. One end of the limiting rod 316 is fixedly connected to the outer wall of the rectangular toothed ring 315. The limiting rod 316 and the limiting ring 317 can facilitate the limiting of the rectangular toothed ring 315, so that the rectangular toothed ring 315 can move horizontally left and right. The grinding disc 326 is located above the sieve plate 327.

[0018] Example 2 The difference from Embodiment 1 is that this embodiment discloses a grinding assembly, such as... Figure 5 As shown: A grinding assembly 32 is also provided on the top of the mounting plate 1. The grinding assembly 32 includes an L-shaped fixing plate 321 fixedly connected to the top of the front of the mounting plate 1. An electric push rod 322 is fixedly connected to the top of the inner wall of the L-shaped fixing plate 321. A fixing frame 323 is fixedly connected to the output end of the electric push rod 322. A drive motor 324 is fixedly connected to the top of the inner wall of the fixing frame 323. A rotating shaft 325 is fixedly connected to the output end of the drive motor 324. A grinding disc 326 is fixedly connected to the other end of the rotating shaft 325. The grinding disc 326 is located inside the support frame 3116. A screening plate 327 is fixedly connected to the inner wall of the support frame 3116. A discharge pipe 328 is connected to the bottom of the support frame 3116. A solenoid valve 329 is fixedly connected to the bottom outer wall of the discharge pipe 328. A collection frame 3210 is provided below the discharge pipe 328. The bottom of the collection frame 3210 is connected to the top of the mounting plate 1. The unit is slidably connected. By setting the grinding assembly 32, when the water-reducing agent needs to be ground, the operator places the water-reducing agent on the top of the screening plate 327, and then activates the electric push rod 322 to extend the electric push rod 322 and push the fixed frame 323 downward so that the bottom of the grinding disc 326 contacts the surface of the water-reducing agent. Then, by activating the drive motor 324, the rotating shaft 325 is rotated. During the rotation of the rotating shaft 325, the grinding disc 326 is rotated, which grinds the water-reducing agent. The ground water-reducing agent is then screened through the screening plate 327. After the water-reducing agent is screened, the operator activates the solenoid valve 329 to discharge the screened water-reducing agent through the discharge pipe 328 into the collection frame 3210 for collection.

[0019] Working principle: When grinding the water-reducing agent, the operator places the water-reducing agent on the top of the sieve plate 327, and then activates the electric push rod 322 to extend it and push the fixed frame 323 downward, so that the bottom of the grinding disc 326 contacts the surface of the water-reducing agent. Then, the operator activates the drive motor 324 to rotate the rotating shaft 325. During the rotation of the rotating shaft 325, the grinding disc 326 will rotate, so that the grinding disc 326 can grind the water-reducing agent. The ground water-reducing agent will be sieved through the sieve plate 327. After the water-reducing agent is sieved, the operator activates the solenoid valve 329 to discharge the sieved water-reducing agent into the collection frame 3210 through the discharge pipe 328, so that the water-reducing agent can be collected through the collection frame 3210. During the grinding process of the water-reducing agent inside the bearing frame 3116, in order to prevent the water-reducing agent from accumulating inside the bearing frame 3116 during grinding, the bearing frame 3116 needs to be vibrated. At this time, the operator turns on the forward and reverse motor 312 to cause the output shaft 313 to rotate. During the rotation of the output shaft 313, it will drive the incomplete gear 314 to rotate. During the rotation of the incomplete gear 314, it will mesh with the inner wall of the rectangular gear ring 315. Under the limitation of the limiting rod 316 and the limiting ring 317, the rectangular gear ring 315 will move left and right. During the movement of the rectangular gear ring 315, the limiting rod 316 will drive the L-shaped plate 319 and the push rod 3110 to move. The push rod 3110 moves. During the process, the push plate 3111 will move, and after moving, the push plate 3111 will squeeze the bearing frame 3116. After being squeezed by the push plate 3111, the bearing frame 3116 will move along the inside of the slide groove 3112 via the slider 3114. After moving, the slider 3114 will move along the outer wall of the crossbar 3113 and squeeze the spring 3115, causing the spring 3115 to compress. When the push plate 3111 stops squeezing the bearing frame 3116, the slider 3114 will reset under the reaction of the spring 3115, causing the bearing frame 3116 to reset. This causes the bearing frame 3116 to vibrate during the grinding of the water-reducing agent, preventing the water-reducing agent from accumulating inside the bearing frame 3116 and affecting the grinding effect.

[0020] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
