Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent production technology, and more specifically to a water-reducing agent raw material feeding device. Background Technology

[0002] Water-reducing agents are chemical admixtures added during the preparation of concrete, mortar, or cement paste. Their main function is to significantly reduce the amount of mixing water without changing the workability of concrete (such as slump), or to greatly improve the fluidity of the mixture under the same water content. At the same time, they can also maintain or enhance the mechanical properties and durability of hardened concrete.

[0003] The shortcomings of the existing technology are as follows: When water-reducing agents and concrete are mixed, the raw materials of water-reducing agents are added to the concrete after mixing. This results in uneven dispersion of the raw materials during mixing, leading to uneven mixing between the concrete and the raw materials of water-reducing agents. Consequently, the water-reducing agent fails to achieve the expected results.

[0004] Therefore, there is a need to provide a water-reducing agent raw material feeding device to solve the above-mentioned problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a water-reducing agent raw material feeding device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a water-reducing agent raw material feeding device, including a mixing cylinder, three support legs fixedly connected to the bottom end of the mixing cylinder, a discharge pipe fixedly connected to the middle of the bottom end of the mixing cylinder, a first hydraulic solenoid valve fixedly sleeved on the outer wall of the discharge pipe, a feeding cylinder fixedly connected to the top end of the mixing cylinder near the left side, a feeding pipe fixedly connected to the bottom end of the feeding cylinder and the top end of the mixing cylinder, a second hydraulic solenoid valve fixedly sleeved on the outer wall of the feeding pipe, a protective shell fixedly connected to the middle of the top end of the mixing cylinder, a controller fixedly connected to the top end of the protective shell, a second inlet fixedly connected to the top end of the mixing cylinder near the right side, and a first inlet fixedly connected to the top end of the feeding cylinder;

[0007] The water-reducing agent raw material feeding device also includes:

[0008] A stirring assembly is disposed within a controller and a mixing cylinder. The mixing cylinder contains two stirring blades, and the stirring assembly is used to drive the two stirring blades to rotate in opposite directions.

[0009] A water volume monitoring component is installed at the top center of the feeding cylinder and is used to monitor the water volume of the water-reducing agent in the feeding cylinder.

[0010] Preferably, the stirring assembly includes:

[0011] A U-shaped frame, with collars fixedly connected to both ends of the U-shaped frame. A first stirring rod is movably sleeved in the middle of one collar, and a first set of bevel gears is fixedly sleeved on the outer wall of the first stirring rod near the bottom end of the collar. A second stirring rod is movably sleeved in the middle of the other collar, and a second set of bevel gears is fixedly sleeved on the outer wall of the second stirring rod.

[0012] A drive mechanism is provided at the U-shaped frame and is used to drive the first and second bevel gears to rotate.

[0013] Preferably, the driving mechanism includes a stirring motor, the bottom end of which is fixedly connected to the right side of the U-shaped frame via a fixing plate, and the transmission end of the stirring motor is fixedly sleeved through the U-shaped frame with a main bevel gear, the outer wall of which meshes with the outer walls of the first and second auxiliary bevel gears.

[0014] Preferably, the water monitoring component includes a guide shell, a guide rod is movably sleeved inside the guide shell, a movable metal plate is fixedly connected to the top of the guide rod, an insulated flexible wire is electrically connected to the top of the movable metal plate, a control power supply is electrically connected to the top of the insulated flexible wire, an alarm is electrically connected to the top of the control power supply, and a suspension ball plate is fixedly connected to the bottom of the guide rod through the feeding cylinder.

[0015] Preferably, a fixed metal plate is fixedly connected to the bottom of the inner side of the guide shell, and the fixed metal plate and the movable metal plate are compatible.

[0016] Preferably, the outer wall of the first stirring rod is movably sleeved with the inner wall of the second stirring rod, both stirring blades are fixedly sleeved with the outer walls of the first and second stirring rods, and the bottom end of the first stirring rod is movably sleeved with the bottom end of the inner wall of the mixing cylinder.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model features a mixing assembly. Supported by a U-shaped frame, the controller activates the mixing motor, which in turn drives the main bevel gear to rotate. This, in turn, drives the first and second auxiliary bevel gears to rotate in opposite directions. With the movable engagement of the collar, the first and second mixing rods rotate in opposite directions. This facilitates the reverse rotation of the two mixing blades inside the mixing drum, resulting in reverse mixing of the concrete and water-reducing agent, thus improving the mixing efficiency of the water-reducing agent and concrete.

[0019] 2. This utility model, by incorporating a water level monitoring component, monitors the content of water-reducing agent in the feeding cylinder. As the water-reducing agent is added to the mixing cylinder and the water level drops, the suspended ball plate drives the guide rod to move downward within the guide shell, thereby moving the movable metal plate towards the fixed metal plate. After the movable metal plate contacts the fixed metal plate, the power is switched on by the insulated flexible wire, controlling the power supply to be turned on. This facilitates the alarm to sound, promptly reminding staff and ensuring timely replenishment of the water-reducing agent in the feeding cylinder. Attached Figure Description

A second stirring rod 906 is movably sleeved in the middle of another collar 908. A second set of bevel gears 907 is fixedly sleeved on the outer wall of the second stirring rod 906. A drive mechanism is provided at the U-shaped frame 901 to drive the first set of bevel gears 904 and the second set of bevel gears 907 to rotate. The drive mechanism includes a stirring motor 902, the bottom end of which is connected to a fixed... The fixed plate is fixedly connected to the right side of the U-shaped frame 901. The transmission end of the stirring motor 902 passes through the U-shaped frame 901 and is fixedly sleeved with the main bevel gear 903. The outer wall of the main bevel gear 903 meshes with the outer walls of the first auxiliary bevel gear 904 and the second auxiliary bevel gear 907. The outer wall of the first stirring rod 905 is movably sleeved with the inner wall of the second stirring rod 906.

The bottom end of the first stirring rod 905 is movably sleeved with the bottom end of the inner wall of the mixing cylinder 1.

[0028] Specifically: the controller 7 turns on the stirring motor 902, which in turn drives the main bevel gear 903 to rotate, which in turn drives the first secondary bevel gear 904 and the second secondary bevel gear 907 to rotate in opposite directions. Under the movable engagement of the collar 908, the first stirring rod 905 and the second stirring rod 906 are driven to rotate in opposite directions, which in turn drives the two stirring blades 10 to rotate in opposite directions inside the mixing cylinder 1. Specific Implementation Example 2

[0030] Please see Figure 1 and Figure 4Based on the first specific embodiment, it also includes a water volume monitoring component 5. The water volume monitoring component 5 is located at the top center of the feeding cylinder 3 and is used to monitor the water volume of the water-reducing agent in the feeding cylinder 3. The water volume monitoring component 5 includes a guide shell 505. A guide rod 506 is movably sleeved inside the guide shell 505. A movable metal plate 504 is fixedly connected to the top of the guide rod 506. An insulated flexible wire 503 is electrically connected to the top of the movable metal plate 504. A control power supply 502 is electrically connected to the top of the insulated flexible wire 503. An alarm 501 is electrically connected to the top of the control power supply 502. A suspension ball plate 507 is fixedly connected through the feeding cylinder 3 at the bottom end of the guide rod 506. A fixed metal plate 508 is fixedly connected to the bottom inside the guide shell 505. The fixed metal plate 508 and the movable metal plate 504 are compatible.

[0031] Specifically: As the water-reducing agent in the feeding cylinder 3 is added to the mixing cylinder 1 and the water level drops, the suspended ball plate 507 drives the guide rod 506 to move downward with the water level in the guide shell 505, thereby driving the movable metal plate 504 to move towards the fixed metal plate 508. After the movable metal plate 504 contacts the fixed metal plate 508, the power is connected under the action of the insulated flexible wire 503, and the control power supply 502 is turned on.

[0032] The working principle of this utility model is as follows: The first feed inlet 4 is opened, and the water-reducing agent is added into the feeding cylinder 3. Then, the second hydraulic solenoid valve 14 is opened, and the water-reducing agent is added into the mixing cylinder 1 through the feeding pipe 13. It mixes with the concrete to improve strength. Supported by the U-shaped frame 901, the controller 7 is activated to control the mixing motor 902, which in turn drives the main bevel gear 903 to rotate. This, in turn, drives the first auxiliary bevel gear 904 and the second auxiliary bevel gear 907 to rotate in opposite directions. Under the movable engagement of the collar 908, the first stirring rod 905 and the second stirring rod 906 rotate in opposite directions, causing the two stirring blades 10 to rotate within the mixing cylinder 1. The internal reverse rotation of the mixing chamber mixes the concrete and water-reducing agent in opposite directions. When monitoring the content of the water-reducing agent in the feeding cylinder 3, as the water-reducing agent is added to the mixing cylinder 1 and the water level drops, the suspended ball plate 507 drives the guide rod 506 to move downward with the water level in the guide shell 505, thereby driving the movable metal plate 504 to move towards the fixed metal plate 508. After the movable metal plate 504 contacts the fixed metal plate 508, the power is turned on under the action of the insulated flexible wire 503, the control power supply 502 is turned on, and the alarm 501 is sounded to promptly remind the staff.
