Description

Technical Field

[0001] This application relates to the field of screening mechanism technology, and in particular to a screening device for preparing composite admixtures. Background Technology

[0002] Composite admixtures are powder materials made by combining two or more mineral admixtures in a certain proportion. Extensive engineering practice and research have shown that concrete with composite admixtures exhibits high strength, high activity index, good durability, and environmental friendliness. Apart from high-quality admixtures such as fly ash and mineral powder, most mineral admixtures exist as solid waste. If treated using low-standard resource utilization methods, they will lead to environmental pollution and other problems. However, composite methods can fully utilize the properties of various admixtures to achieve efficient and low-carbon applications. The preparation process of composite admixtures requires screening of various raw materials to obtain granular raw materials that meet the requirements, ensuring the quality of the finished product during mixing and preparation.

[0003] The patent document with publication number CN211275465U provides a concrete material gradation screening device for slag admixture. When screening materials of different specifications, the screening plate can be easily replaced. When using the device, only the screening plate of the required specification needs to be replaced, and there is no need to purchase new equipment, thus reducing screening costs.

[0004] However, the above-mentioned device cannot discharge the screened material and the blocked material simultaneously without affecting the screening operation. This is not conducive to the timely recycling of the blocked material, and the material blocked by the screening structure needs to be cleaned manually periodically, which is not convenient for continuous screening. Therefore, in order to solve the above problems, a screening device for the preparation of composite admixtures is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a screening device for the preparation of composite admixtures, which overcomes the deficiencies of existing technologies and aims to solve the problem that the device is unable to discharge the screened material and the blocked material simultaneously without affecting the screening operation.

[0006] To achieve the above objectives, this application provides the following technical solution: A screening device for preparing composite admixtures includes a box-shaped outer shell, a swaying support fixedly disposed inside the box-shaped outer shell, an inclined screening platform fixedly connected to the swaying support, a driving mechanism fixedly disposed in the upper part of the box-shaped outer shell, a transmission component fixedly connected to the upper side of the screening platform, the driving mechanism being fixedly connected to the transmission component, a feed hopper fixedly disposed in the upper oblique part of the box-shaped outer shell, and a material distribution baffle fixedly disposed in the lower part of the box-shaped outer shell, the material distribution baffle consisting of a guide plate and a recovery guide plate.

[0007] By adopting the above technical solution, when the material slides from the feed hopper onto the screening table, the material will continue to slide down the screening table due to its inclined arrangement. At the same time, the screening table will shake under the drive mechanism, accelerating the screening process. This allows the material that can pass through the screen to be screened out before reaching the bottom of the screening table and discharged through the guide plate. The material that cannot pass through the screen will reach the bottom of the screening table and fall onto the recovery guide plate, where it will be guided out. This prevents the accumulation of material in the mechanism, eliminates the need for cleaning, and improves work efficiency.

[0008] As a preferred technical solution of this application, the guide plate is fixedly arranged directly below the screening table, and the recycling guide plate is fixedly arranged below the bottom end of the screening table.

[0009] By adopting the above technical solution, the screened material on the screening table can be discharged by the guide plate, and the unscreened material falling from the bottom of the screening table can be removed by the recovery guide plate.

[0010] As a preferred technical solution of this application, the swaying support includes a support beam fixedly connected to the box-shaped shell, support springs are fixedly provided on both sides of the upper end face of the support beam, and a support plate is fixedly provided on the top of the support spring.

[0011] By adopting the above technical solution, the screening table can be supported and fixed without restricting its mobility in multiple directions, allowing the screening table to sway under the driving force of the external structure, thereby improving the screening effect and speed.

[0012] As a preferred technical solution of this application, the screening table includes a base plate, a mounting groove is provided in the middle of the base plate and a sieve plate is detachably installed therein, a side guide plate is fixedly provided at both sides of the upper surface of the base plate, and an end baffle is fixedly provided on the upper surface of the side guide plate near the feed hopper.

[0013] By adopting the above technical solution, the screening conditions can be changed by replacing the screen plate, thereby improving the overall applicability of the mechanism. The side guide plate and end baffle plate can prevent the material from falling from both sides of the screen plate, and at the same time, they can guide the material as it slides down, so that the material can slide onto the screen plate in an orderly manner to start screening.

[0014] As a preferred technical solution of this application, the driving mechanism includes a motor bracket and a fixing plate fixedly mounted on the upper end of the box-shaped outer shell. A drive motor is installed in the motor bracket. A grooved plate is fixedly mounted in the middle of the fixing plate. A slider is slidably mounted in the grooved plate. A long transmission rod is rotatably connected to the slider. A short transmission rod is rotatably connected to the output shaft of the driving mechanism. The long transmission rod and the short transmission rod are rotatably connected. A connecting rod is fixedly connected to the lower end face of the slider.

[0015] By adopting the above technical solution, the short transmission rod is driven by the drive motor to rotate. The short transmission rod can drive the long transmission rod to move and eventually drive the slider to slide in the grooved plate. The connecting rod fixed on the slider will move back and forth synchronously, thereby applying axial thrust or pull force to the transmission component and driving the entire screening table to shake.

[0016] As a preferred technical solution of this application, the transmission component includes a connecting beam fixedly connected to the end of the connecting rod, and transmission springs are fixedly provided on both sides of the lower end face of the connecting beam, with a connecting piece fixedly connected to the bottom end of the transmission spring.

[0017] By adopting the above technical solution, a flexible connection between the transmission component and the screening table can be achieved by using a transmission spring. That is, the transmission component can transmit pushing and pulling force to the screening table without restricting the shaking of the screening table.

[0018] As a preferred technical solution of this application, the top plate of the box-shaped outer shell is provided with a feed inlet communicating with the feed hopper, the bottom of the feed inlet is provided with an inclined opening facing the screening table, and the side plates of the box-shaped outer shell are respectively provided with a discharge port and a recovery port, wherein the bottom of the discharge port is flush with the upper surface of the guide plate, and the bottom of the recovery port is flush with the upper surface of the recovery guide plate.

[0019] By adopting the above technical solution, a complete material path can be formed in the working process of the mechanism. That is, the material enters the interior of the mechanism from the feed port and falls onto the screening table through the inclined port. The screened material is discharged through the guide plate, and the unscreened material is discharged through the recovery guide plate.

[0020] The beneficial effects of this application are as follows: Since the screening table is arranged at an incline, the material will continue to slide down the screening table. At the same time, the screening table will shake under the drive mechanism, which accelerates the screening of the material. This allows the material that can be screened to be completely screened and discharged through the guide plate before it reaches the bottom of the screening table. The material that cannot be screened will reach the bottom of the screening table and fall onto the recovery guide plate, which will guide it out. This prevents the accumulation of material in the mechanism, eliminates the need for cleaning, and improves work efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Reference Figure 1 A screening device for preparing composite admixtures includes a box-shaped outer shell 1. A swaying support 2 is fixedly installed inside the box-shaped outer shell 1. An inclined screening table 3 is fixedly connected to the swaying support 2. A drive mechanism 4 is fixedly installed in the upper part of the box-shaped outer shell 1. A transmission component 5 is fixedly connected to the upper side of the screening table 3. The drive mechanism 4 is fixedly connected to the transmission component 5. A feed hopper 6 is fixedly installed at the upper angle inside the box-shaped outer shell 1. A material distribution baffle 7 is fixedly installed in the lower part of the box-shaped outer shell 1. The material distribution baffle 7 consists of a guide plate 71 and a recovery guide plate 72. When material flows from... When the feed hopper 6 slides down to the screening table 3, the material will continue to slide down the screening table 3 due to the inclined arrangement of the screening table 3. At the same time, the screening table 3 will shake under the drive mechanism 4, which will accelerate the screening of the material. This will allow the material that can be screened to be completely screened and discharged through the guide plate 71 before it reaches the bottom of the screening table 3. The material that cannot be screened will reach the bottom of the screening table 3 and fall onto the recovery guide plate 72, which will guide it out. This will prevent the accumulation of material in the mechanism and eliminate the need for cleaning, thereby improving work efficiency.

[0025] Reference Figure 2The swaying support 2 includes a support beam 21 fixedly connected to the box-shaped outer shell 1. Support springs 22 are fixedly installed on both sides of the upper end face of the support beam 21, and support plates 23 are fixedly installed on the top of the support springs 22. By adopting the above technical solution, the screening table 3 can be supported and fixed without restricting its mobility in multiple directions, so that the screening table 3 can sway under the driving action of the external structure, thereby improving the screening effect and speed.

[0026] Reference Figure 2 The screening table 3 includes a base plate 31. The base plate 31 has an installation groove in the middle and a screen plate 32 is detachably installed therein. Side guide plates 33 are fixedly installed on both sides of the upper surface of the base plate 31. An end baffle plate 34 is fixedly installed on the upper surface of the side guide plate 33 near the feed hopper 6. The screening conditions can be changed by replacing the screen plate 32, thereby improving the overall applicability of the mechanism. The side guide plates 33 and the end baffle plate 34 can prevent the material from falling from both sides of the screen plate 32 and guide the material as it slides down, so that the material can slide onto the screen plate 32 in an orderly manner to start screening.

[0027] Reference Figure 3 The drive mechanism 4 includes a motor bracket 41 and a fixing plate 43 fixedly mounted on the upper end of the box-shaped outer shell 1. A drive motor 42 is installed in the motor bracket 41. A grooved plate 44 is fixedly mounted in the middle of the fixing plate 43. A slider 45 is slidably mounted in the grooved plate 44. A long transmission rod 46 is rotatably connected to the slider 45. A short transmission rod 47 is rotatably connected to the output shaft of the drive mechanism 4. The long transmission rod 46 and the short transmission rod 47 are rotatably connected. A connecting rod 48 is fixedly connected to the lower end face of the slider 45. By adopting the above technical solution, the drive motor 42 drives the short transmission rod 47 to rotate. The short transmission rod 47 can drive the long transmission rod 46 to move and finally drive the slider 45 to slide in the grooved plate 44. The connecting rod 48 fixedly mounted on the slider 45 will move back and forth synchronously, thereby applying an axial thrust or pull force to the transmission component 5, driving the screening table 3 to shake as a whole.

[0028] Reference Figure 3 The transmission component 5 includes a connecting beam 51 fixedly connected to the end of the connecting rod 48. Transmission springs 52 are fixedly installed on both sides of the lower end face of the connecting beam 51. A connecting piece 53 is fixedly connected to the bottom end of the transmission spring 52. The transmission spring 52 can realize a flexible connection between the transmission component 5 and the screening table 3. That is, the transmission component 5 can transmit the pushing and pulling force to the screening table 3, while not restricting the shaking of the screening table 3.

[0029] Reference Figure 4The guide plate 71 is fixedly installed directly below the screening table 3, and the recovery guide plate 72 is fixedly installed below the bottom of the screening table 3. The top plate of the box-shaped outer shell 1 has an inlet 11 that communicates with the feed hopper 6. The bottom of the inlet 11 has an inclined opening 61 facing the screening table 3. The side plates of the box-shaped outer shell 1 have outlets 12 and recovery ports 13 respectively. The bottom of the outlet 12 is flush with the upper surface of the guide plate 71, and the bottom of the recovery port 13 is flush with the upper surface of the recovery guide plate 72. By adopting the above technical solution, a complete material passage can be formed in the working process of the mechanism. That is, the material enters the interior of the mechanism from the inlet 11 and falls onto the screening table 3 through the inclined opening 61. The screened material is discharged through the guide plate 71, and the unscreened material is discharged through the recovery guide plate 72.

[0030] Working principle: Material is added into the feed hopper 6 through the feed inlet 11. Under the action of gravity, the material slides out from the inclined opening 61 and falls onto the screening table 3. Since the screening table 3 is inclined, the material continues to slide down the screening table 3 and is screened on the screen plate 32. At the same time, the drive motor 42 drives the short transmission rod 47 to rotate. The short transmission rod 47 can drive the long transmission rod 46 to move and finally drive the slider 45 to slide in the grooved plate 44. The connecting rod 48 fixed on the slider 45 will move back and forth synchronously, thereby applying axial thrust or pull force to the transmission component 5, driving the entire screening table 3 to shake, accelerating the screening of the material. This allows the material that can be screened to be completely screened and discharged through the guide plate 71 before reaching the bottom of the screening table 3, while the material that cannot be screened can reach the bottom of the screening table 3 and fall onto the recovery guide plate 72, which guides it out. This prevents the accumulation of material in the mechanism, eliminates the need for cleaning, and improves work efficiency.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
