Technical Field

[0001] This utility model relates to the field of admixture production technology, specifically a sieving device for concrete admixtures. Background Technology

[0002] With the continued prosperity of the construction industry, the market demand for concrete admixtures, as key materials for improving concrete performance, is constantly expanding. Various admixtures, such as water-reducing agents, accelerators, and retarders, are widely used in construction projects to enhance the strength, durability, and workability of concrete. In the production process of concrete admixtures, sieving is a crucial step in ensuring product quality. It removes impurities, controls particle size distribution, and allows the admixtures to function more effectively. While existing sieving devices for concrete admixtures generally meet daily usage needs, some shortcomings still require improvement.

[0003] Most of the screening devices widely used in the market for concrete admixtures adopt traditional vibrating equipment, which usually uses a single transverse vibration mode. The movement trajectory of the material on the screen surface is relatively simple, which easily leads to screen hole blockage. When clearing the screen holes, it is necessary to clean the material on the screen plate, which is a cumbersome process. Therefore, we propose a screening device for concrete admixtures to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a sieving device for concrete admixtures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sieving device for concrete admixtures, comprising a frame, a housing installed within the frame, and a discharge port located at the bottom of the housing. A rotating drum is rotatably connected to the upper end of the housing. A servo motor is installed at the right end of the frame, and the output end of the servo motor is connected to the middle of the right end of the rotating drum. A screen is provided in the middle of the rotating drum. Multiple sets of feeding ports are equally spaced on the left side of the rotating drum. Multiple sets of sliding blocks are equally spaced on the outer wall of the left side of the feeding ports along the axis of the feeding ports. A turntable is provided outside the multiple sets of sliding blocks. Multiple sets of sliding grooves are equally spaced on the turntable along the axis of the turntable. The multiple sets of sliding blocks are all located inside the sliding grooves. Multiple sets of through holes are equally spaced on the turntable. A positioning component is provided in the middle of the feeding port.

[0006] As a further preferred embodiment of this technical solution, the positioning assembly includes a sleeve, a guide slider, a positioning rod, a push rod, a return spring, a positioning hole one, and a positioning hole two. A sleeve is fixed to the outer wall of the left end of the feeding port. A guide slider is provided inside the sleeve. A positioning rod is provided at the end of the guide slider facing the turntable. A push rod is installed on the outer wall of the left side of the guide slider. A return spring is provided at the end of the guide slider away from the turntable.

[0007] As a further preferred embodiment of this technical solution, the number of through holes on the turntable corresponds to the number of feeding ports on the rotating drum.

[0008] As a further preferred embodiment of this technical solution, the outer wall of the guide slider is fully fitted with the inner wall of the sleeve, and the guide slider and the sleeve are slidably connected.

[0009] As a further preferred embodiment of this technical solution, the outer wall of the push rod is provided with anti-slip texture.

[0010] As a further preferred embodiment of this technical solution, the two ends of the reset spring are respectively connected to the outer wall of the guide slider and the inner wall of the sleeve, and the guide slider is elastically connected to the inner wall of the sleeve through the reset spring.

[0011] This utility model provides a sieving device for concrete admixtures, which has the following beneficial effects:

[0012] 1. This utility model features a rotatable drum mounted on a housing, with a screen installed on the drum. Material is fed into the drum through a feeding port on its side, and a servo motor drives the drum to rotate. The screen on the drum rotates and screens the material. When the screen holes become clogged, the drum can be rotated to move the clogged area to the top, allowing the material to be cleared from the outside of the screen without removing the material from the drum. This simplifies the clearing process and improves the convenience of using the device.

[0013] 2. This utility model has a movable guide slider installed on the rotating drum. The return spring releases its elastic force to push the guide slider, which in turn drives the positioning rod to insert into the positioning hole. This effectively prevents the turntable from loosening during the rotation of the drum and improves the stability of the device during use. Attached Figure Description

If the specific posture changes, the directional indicator will also change accordingly.

[0022] Meanwhile, the meaning of "and / or" or "and / or" appearing throughout the text is that it includes three options. Taking "A and / or B" as an example, it includes option A, option B, or an option that satisfies both A and B.

[0023] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0024] This utility model provides a technical solution: such as Figures 1 to 5As shown in this embodiment, a sieving device for concrete admixtures includes a frame 1, a housing 2 installed inside the frame 1, and a discharge port 3 located at the bottom of the housing 2. A rotating drum 4 is rotatably connected to the upper end of the housing 2. A servo motor 6 is installed at the right end of the frame 1, and the output end of the servo motor 6 is connected to the middle of the right end of the rotating drum 4. A screen 5 is provided in the middle of the rotating drum 4. Multiple sets of feeding ports 7 are equally spaced on the left side of the rotating drum 4. Multiple sets of sliding blocks 8 are fixed equally spaced along the axis of the feeding ports 7 on the outer wall of the left side of the feeding ports 7. A turntable 9 is provided outside the multiple sets of sliding blocks 8. Multiple sets of sliding grooves 10 are equally spaced along the axis of the turntable 9. The multiple sets of sliding blocks 8 are all located inside the sliding grooves 10. Multiple sets of through holes 11 are equally spaced on the turntable 9. A positioning component is provided in the middle of the feeding port 7.

[0025] By installing a rotatable drum 4 on the housing 2 and a screen 5 on the drum 4, materials can be placed into the drum 4 through the feeding port 7 on the side of the drum 4. Then, the servo motor 6 drives the drum 4 to rotate, and the screen 5 on the drum 4 rotates and screens the materials during the rotation. When the screen holes on the screen 5 are blocked, the drum 4 can be rotated to rotate the blockage on the screen 5 to the top, so that the blockage can be cleared outside the screen 5. There is no need to take the materials out of the drum 4, which effectively simplifies the unblocking process and improves the convenience of using the device.

[0026] In other embodiments, the positioning assembly includes a sleeve 12, a guide slider 13, a positioning rod 14, a push rod 15, a return spring 16, a positioning hole 17 and a positioning hole 18. The sleeve 12 is fixed to the outer wall of the left end of the feeding port 7. The guide slider 13 is provided inside the sleeve 12. The positioning rod 14 is provided at the end of the guide slider 13 facing the turntable 9. The push rod 15 is installed on the outer wall of the left side of the guide slider 13. The return spring 16 is provided at the end of the guide slider 13 away from the turntable 9.

[0027] By installing a movable guide slider 13 on the rotating drum 4, when the turntable 9 needs to be rotated, the push rod 15 can be pushed, causing the guide slider 13 to move the positioning rod 14 downward along the sleeve 12, so that the guide slider 13 moves the positioning rod 14 completely out of the positioning hole 17 on the turntable 9, and the guide slider 13 squeezes the return spring 16, which then pushes the turntable 9 to rotate along the multiple sets of slides 8. When the through hole 11 leaves the outside of the feeding port 7, the force on the push rod 15 is released, and the return spring 16 releases its elasticity to push the guide slider 13, so that the guide slider 13 moves the positioning rod 14 into the positioning hole 18. This effectively prevents the turntable 9 from loosening during the rotation of the rotating drum 4, and improves the stability of the device during use.

[0028] In other embodiments, the number of through holes 11 on the turntable 9 corresponds to the number of feeding ports 7 on the rotating drum 4;

[0029] This design allows the through hole 11 on the turntable 9 to be moved to the outside of the feeding port 7, making it easier to feed the ingredients into the turntable 4 from the feeding port 7 on the turntable 4.

[0030] In other embodiments, the outer wall of the guide slider 13 is fully fitted with the inner wall of the sleeve 12, and the guide slider 13 and the sleeve 12 are slidably connected.

[0031] This design effectively prevents the guide slider 13 from shaking during its movement as it moves laterally within the sleeve 12, thus improving the stability of the guide slider 13 during movement.

[0032] In other embodiments, the outer wall of the push rod 15 is provided with anti-slip texture;

[0033] This design effectively increases the friction between the user's hand and the outside of the push rod 15 when it needs to be pushed, thus making it easier to push the push rod 15.

[0034] In other embodiments, the two ends of the return spring 16 are respectively connected to the outer wall of the guide slider 13 and the inner wall of the sleeve 12, and the guide slider 13 is elastically connected to the inner wall of the sleeve 12 through the return spring 16;

[0035] This design allows the return spring 16 to exert a continuous elastic force on the guide slider 13 toward the turntable 9, enabling the guide slider 13 to drive the positioning rod 14 to quickly insert into the positioning hole 17 or positioning hole 18 on the turntable 9.

[0036] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
