Description

Technical Field

[0001] This utility model belongs to the field of early strength agent preparation technology, and more specifically, it relates to an early strength agent preparation stirring device. Background Technology

[0002] As a key admixture in concrete construction, the formulation quality of early-strength agents directly determines the early strength development effect of concrete. It is of great significance for shortening the construction period and ensuring the safety of low-temperature construction. With the continuous improvement of construction efficiency and quality requirements in building engineering, the demand for industrialized and standardized formulation of early-strength agents is becoming increasingly urgent.

[0003] Current early-strength agent mixing devices still have the following shortcomings:

[0004] Current methods for preparing early-strength agents mostly rely on segmented operations and lack integrated crushing equipment. The entire process requires multiple manual transfers, which not only increases labor intensity but also affects production efficiency. Furthermore, when crushing solid early-strength agents, the lack of a screening structure makes it difficult to fully break down moisture-absorbing and clump-forming solid early-strength agents (such as sodium sulfate and calcium chloride). Large residual raw materials directly enter the mixing stage, leading to uneven distribution of the effective components of the early-strength agent and affecting the molding quality of concrete. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an early-strength agent preparation and mixing device. This addresses the issues raised in the background art, where existing early-strength agent preparation relies heavily on segmented operations, lacks integrated crushing equipment, affects production efficiency, and results in uneven distribution of the effective components of the early-strength agent and affects the molding quality of concrete when large residual raw materials directly enter the mixing process.

[0006] The purpose and effect of this utility model's early strength agent preparation stirring device are achieved by the following specific technical means:

[0007] A mixing device for preparing an early-strength agent includes: a base plate; the base plate has a rectangular plate structure; a mixing trough with a rectangular groove structure is fixedly installed on the top of the base plate; four sets of cylindrical fixing rods are fixedly installed in a rectangular array around the top of the mixing trough, and springs are sleeved on the outer side of the fixing rods; a sieve with a circular groove structure is slidably installed on the outer side between the four sets of fixing rods, and a filter hole structure is opened in a ring array at the bottom of the sieve; a through rectangular channel structure is opened on one side of the bottom of the sieve; a scraper with a wedge-shaped plate structure is rotatably installed on the inner side of the sieve, and the bottom end face of the scraper is in contact with the sieve; a collection trough with a U-shaped channel structure is fixedly installed at the bottom of the rectangular channel at the bottom of the sieve, and the collection trough is inclined.

[0008] Furthermore, a cylindrical tank is fixedly installed on the top of the base plate, and a discharge port structure is opened at the bottom of the tank. A circular cover plate is installed on the top of the tank. A first motor is fixedly installed in the middle of the top of the tank. An agitator is rotated inside the tank and is connected to the first motor for transmission. Four sets of discharge pipes are connected in a ring array at the bottom of the mixing tank. The lower end of the discharge pipe passes through the cover plate on the top of the tank and extends into the inside of the tank. A solenoid valve switch is installed on the outside of the discharge pipe.

[0009] Furthermore, a rectangular groove structure is fixedly provided on the top of the mixing tank, and a feeding port structure is provided at the bottom of the crushing tank; a set of crushing rollers is rotatably provided on both sides of the inside of the crushing tank; a set of second motors is fixedly provided on both sides of the crushing tank, and the second motors are connected to the crushing rollers for transmission.

[0010] Furthermore, a third motor is fixedly installed on one side of the top of the mixing tank; a cam is driven to one side of the third motor, and the outer wall of the cam is in contact with the bottom end face of the screen tank.

[0011] Furthermore, a mixing roller is rotatably installed inside the mixing tank, and the mixing roller is connected to a third motor via a transmission belt; a fourth motor is fixedly installed at the bottom of the sieve tank, and the fourth motor is connected to a scraper via a transmission belt.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The device integrates the crushing tank, screening tank, mixing tank, and tank (concrete mixing) on ​​the same base plate, realizing full automation of the "raw material feeding-pretreatment-mixing-finished product discharge" process. No manual transfer is required. Solid raw materials are fed into the crushing tank and undergo crushing, screening, and preliminary mixing in sequence. Finally, they are directly transported to the tank to fuse with the concrete base material. The whole process is continuous and uninterrupted. Compared with the traditional segmented operation, the production efficiency is greatly improved. It can meet the continuous and batch supply needs of early strength agents for engineering projects, while reducing manual intervention and labor intensity.

[0014] The sieve trough is driven by a cam to actively vibrate up and down. Combined with the bottom annular array of filter holes, it can quickly separate qualified raw materials from large particles of impurities, greatly improving screening efficiency. At the same time, the cooperative structure of the scraper and the collection trough can collect and recycle large particles of raw materials that have not passed the screening, and put them back into the crushing trough for secondary processing, improving the utilization rate of raw materials and avoiding waste. The tight fit design between the scraper and the sieve trough can also clean the fine material clogging the sieve holes in real time, ensuring stable screening effect.

[0015] The mixing rollers in the mixing tank are linked to the screening motor via a transmission belt. They are stirred synchronously as the raw materials fall in, and with the turbulence effect of the stirring paddle, the solid raw materials and liquid components can be mixed evenly to avoid stratification. Moreover, the mixing process is carried out simultaneously with the screening, which shortens the overall processing time. Attached Figure Description

[0025] This utility model provides a mixing device for preparing an early-strength agent, comprising: a base plate 1; the base plate 1 adopts a rectangular plate structure; a mixing tank 105 with a rectangular groove structure is fixedly provided on the top of the base plate 1, the mixing tank 105 is used for preliminary mixing of the early-strength agent after crushing and screening; four sets of cylindrical fixing rods 109 are fixedly arranged in a rectangular array around the top of the mixing tank 105, and springs are sleeved on the outer side of the fixing rods 109, the springs can provide elastic support and reset function for the sieve 110; a sieve 110 with a circular groove structure is slidably arranged on the outer side between the four sets of fixing rods 109, and the bottom of the sieve 110 has a filter hole structure in a ring array. The screen 10 can slide up and down on the fixed rod 109 to achieve the screening function. A through rectangular channel structure is provided on one side of the bottom of the screen 110 to discharge large particles of raw material that have not passed the screening. A wedge-shaped scraper 111 is rotatably provided on the inner side of the screen 110, and the bottom end face of the scraper 111 is in contact with the screen 110. When the scraper 111 rotates, it can scrape the large particles of raw material that have not passed the screening in the screen 110 to the rectangular channel for discharge. A U-shaped channel structure collection trough 112 is fixedly provided at the bottom of the rectangular channel at the bottom of the screen 110. The collection trough 112 is inclined to facilitate the collection and discharge of large particles of raw material, which can be recycled and crushed again.

[0026] The mixing tank 105 has a rectangular groove structure crushing tank 106 fixedly installed on its top, and the bottom of the crushing tank 106 has a feeding port structure. A set of crushing rollers 107 are rotatably installed on both sides of the inside of the crushing tank 106. The two sets of crushing rollers 107 rotate relative to each other to crush the raw materials. A set of second motors 108 are fixedly installed on both sides of the crushing tank 106. The second motors 108 are connected to the crushing rollers 107. The two sets of second motors 108 rotate in opposite directions to ensure that the crushing rollers 107 can rotate relative to each other to carry out the crushing operation.

[0027] A third motor 113 is fixedly installed on one side of the top of the mixing tank 105; a cam 114 is connected to one side of the third motor 113 for transmission, and the outer wall of the cam 114 is in contact with the bottom end face of the screen trough 110. When the third motor 113 drives the cam 114 to rotate, the cam 114 pushes the screen trough 110 to slide up and down on the fixed rod 109 to achieve the screening function.

[0028] The mixing tank 105 is equipped with a mixing roller 115, which is connected to a third motor 113 via a transmission belt. The third motor 113 drives the mixing roller 115 to rotate, thus performing preliminary mixing of the raw materials entering the mixing tank 105. The mixing roller 115 is equipped with an agitator to improve the mixing effect. The bottom of the sieve 110 is fixedly equipped with a fourth motor 116, which is connected to a scraper 111 to provide rotational power for the scraper 111.

[0029] The specific usage and function of this embodiment are as follows:

[0030] The pretreated solid early-strength agent raw material is slowly fed into the crushing tank 106, taking care to control the feeding speed to avoid excessive accumulation of raw material in the crushing tank 106, which would affect the crushing efficiency. Two sets of second motors 108 are started, driving the crushing rollers 107 to rotate relative to each other, crushing the raw material. The initially crushed early-strength agent raw material falls through the crushing tank 106 into the lower sieve tank 110. The third motor 113 is then started, driving the cam 114 to rotate. During rotation, the cam 114 continuously pushes the sieve tank 110 to slide up and down on the fixed rod 109, using the vibration of the sieve tank 110 to achieve the screening function of the crushed raw material. Raw material meeting the particle size requirements falls through the filter holes at the bottom of the sieve tank 110 into the lower mixing tank 105, while large particles that do not pass through the filter holes remain in the sieve tank 110. Simultaneously, the third motor 113... The transmission belt drives the mixing roller 115 in the mixing tank 105 to rotate. At the same time, water and early strength agent are added to the mixing tank 105 for mixing. The early strength agent raw material and the water in the mixing tank 105 are stirred and mixed. The stirring paddle on the mixing roller 115 rotates with the mixing roller 115 to maintain the fluidity of the space in the mixing tank 105, so that the raw material falling in can be evenly distributed. After the screen 110 vibrates and screens for a period of time, the fourth motor 116 is started. The fourth motor 116 drives the scraper 111 to rotate inside the screen 110. The scraper 111 scrapes the large particles of raw material that have not passed the screening in the screen 110 to the rectangular through groove at the bottom of the screen 110. The large particles of raw material fall into the inclined collection trough 112 below through the rectangular through groove and are finally discharged from the collection trough 112. The discharged large particles of raw material can be collected and put back into the crushing tank 106 for secondary crushing treatment to complete the entire early strength agent treatment process.

[0032] A cylindrical tank 101 is fixedly mounted on the top of the base plate 1, and a discharge port is provided at the bottom of the tank 101. A circular cover plate is provided on the top of the tank 101. The tank 101 serves as a mixing container for concrete and early-strength agent. A first motor 102 is fixedly mounted in the middle of the top of the tank 101. An agitator 103 is rotatably mounted inside the tank 101, and the agitator 103 is connected to the first motor 102. The first motor 102 drives the agitator 103 to rotate to achieve the agitation function. Four sets of feed pipes 104 are connected in a ring array at the bottom of the mixing tank 105 to transport the preliminarily mixed raw materials in the mixing tank 105 to the tank 101. The lower end of the feed pipe 104 passes through the cover plate on the top of the tank 101 and extends into the interior of the tank 101. A solenoid valve switch is provided on the outside of the feed pipe 104 to precisely control the amount and time of raw material delivery.

[0033] The specific usage and function of this embodiment are as follows:

[0034] In this invention, after the early-strength agent in the mixing tank 105 is mixed, concrete can be added to the tank 101, and the solenoid valves on each set of feed pipes 104 can be activated to add the prepared early-strength agent from all sides into the tank 101. Then, the first motor 102 is started to drive the mixing roller 103 to mix the concrete and the early-strength agent, thereby completing the entire mixing process of concrete and early-strength agent.
