Description

A quantitative feeding device for the production of organosilicon materials Technical Field

[0001] This utility model relates to the technical field of quantitative feeding devices, and in particular to a quantitative feeding device for the production of organosilicon materials. Background Technology

[0002] In the field of organosilicon material production, screw conveyors are commonly used material conveying equipment. Their working principle involves a motor driving a screw shaft to rotate, using screw blades to propel materials upwards along a screw trajectory, thereby conveying materials from a low point to a high point, or from storage containers to processing equipment. Screw conveyors have a relatively simple structure, low cost, and can achieve continuous conveying, making them widely used in organosilicon material production lines. For example, in the production of organosilicon rubber, various solid raw materials (such as silicon powder and fillers) need to be conveyed to mixing equipment for mixing. Screw conveyors can lift these raw materials from storage silos and convey them to the feed inlet above the mixing vessel, achieving automatic feeding.

[0003] However, in the feeding scenario of organosilicon materials, screw feeders have limitations due to feeding accuracy issues: organosilicon material production requires high precision in raw material ratios; however, large spaces and gaps inevitably arise between the screw and the material trough wall in the screw feeder, which cannot always maintain a close contact state, resulting in a certain error in the feeding amount each time, making it difficult to meet the high-precision production requirements; for example, in the production of high-purity organosilicon electronic materials, even small deviations in the raw material ratio can affect the product performance; in view of this, we propose a quantitative feeding device for organosilicon material production. Summary of the Invention

[0004] The main objective of this invention is to provide a quantitative feeding device for the production of organosilicon materials, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quantitative feeding device for the production of organosilicon materials includes a screw feeder, a discharge pipe fixedly installed at the top of the screw feeder, a quantitative weighing bucket suspended directly below the discharge pipe, and a powder particle discharge control valve fixedly connected to the bottom of the quantitative weighing bucket.

[0007] Two or more tension-type transmission sensors are connected between the top outer ring of the quantitative weighing barrel and the outer wall of the discharge pipe.

[0008] Preferably, a viscous damper is connected above the tension-type transmission sensor, a ring is fixedly connected to the top of the viscous damper, and several connecting rods are fixedly connected to the outer wall of the discharge pipe, with the inner ring of the ring fitting around the outer periphery of the connecting rods.

[0009] Preferably, a rotating wheel is rotatably connected below the viscous damper, and a screw rod is coaxially fixedly connected below the rotating wheel. The lower end of the screw rod is threadedly connected to the top of the tension-type transmission sensor.

[0010] Preferably, a plurality of connecting lugs are fixedly installed on the outer ring of the top of the quantitative weighing barrel, and a connecting ring is fixedly connected below the elastic element in the tension-type transmission sensor, the connecting ring being connected to the inner ring of the connecting lugs.

[0011] Preferably, the powder particle discharge control valve is an electric butterfly valve, and a vibration motor is fixedly installed on the outer wall of the electric butterfly valve.

[0012] Preferably, a tension spring is coaxially arranged around the periphery of the viscous damper, and the two ends of the tension spring are fixedly connected to the two ends of the viscous damper, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. High-precision quantitative feeding: This utility model uses multiple tension-type transmission sensors to weigh the quantitative weighing barrel, which can accurately monitor the weight of the organosilicon material in the barrel in real time. In conjunction with the control system in the screw feeder, the rotation speed of the screw feeder screw is slowed down when the preset weight is about to be reached, so as to achieve precise feeding, effectively improve the feeding accuracy, meet the high precision requirements of raw material ratio in organosilicon material production, and help improve the stability and consistency of product quality.

[0015] 2. Reduce dust pollution: The entire device adopts a closed or semi-closed structure, which reduces the contact between materials and the outside air during the conveying and weighing process, and reduces the possibility of dust flying. In addition, dust collection devices can be equipped at the discharge port and other parts that are prone to dust generation, to further reduce dust pollution to the production environment and protect the health of operators and the safety of the production workshop.

[0016] 3. Improve production efficiency: The automated quantitative feeding process reduces manual intervention, shortens feeding time, and improves production efficiency; at the same time, precise feeding control avoids production interruptions or product defects caused by feeding errors, further improving overall production efficiency.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As shown in Figures 1-3, a quantitative feeding device for the production of organosilicon materials includes a screw feeder 1, a discharge pipe 2, a quantitative weighing bin 3, and a powder particle discharge control valve 4. The components work together to achieve precise quantitative feeding. The screw feeder 1 is the basic feeding equipment of this utility model. Its function is to transport organosilicon particle materials from the storage location to the designated location. In actual production scenarios, the screw structure inside the screw feeder 1 rotates under the drive of a motor, pushing the organosilicon particles upward along the screw trajectory and discharging them through the discharge pipe 2. The discharge pipe 2 is fixedly installed at the top of the screw feeder 1 as a channel for material discharge. Its position and angle design ensure that the material can accurately fall into the quantitative weighing bin 3 below.

[0023] Referring to Figure 2, the quantitative weighing barrel 3 is cylindrical in shape and is placed directly below the discharge port of the discharge pipe 2. Three tension-type transmission sensors 8 are evenly distributed around the top outer ring of the quantitative weighing barrel 3. Through these three tension-type transmission sensors 8, the weight of the organosilicon granules contained in the barrel can be accurately measured. The principle is based on the elastic element inside the tension-type transmission sensor 8. When subjected to the gravity of the material, the elastic element deforms and is converted into an electrical signal output. After processing, the weight data of the material is obtained.

[0024] Referring to Figure 2, the powder particle discharge control valve 4 is preferably an electric butterfly valve. The powder particle discharge control valve 4 is installed below the quantitative weighing barrel 3. It is mainly responsible for realizing automated discharge. According to the instructions of the control system, the electric butterfly valve can quickly and accurately control the opening and closing of the discharge, as well as the discharge volume. On the outer wall of the electric butterfly valve, a vibration motor 5 is symmetrically installed. The vibration motor 5 plays a crucial role. By reasonably counterweighting, the center of the entire electric butterfly valve and the vibration motor 5 is made to coincide with the central axis of the quantitative weighing barrel 3. When working, the vibration motor 5 generates vibration force to shake the organosilicon powder particles falling into the quantitative weighing barrel 3 as evenly as possible, avoiding uneven material accumulation that affects the weighing accuracy.

[0025] Referring to Figure 3, the tension-type transmission sensors 8 are evenly distributed on the top outer ring of the quantitative weighing barrel 3. Each tension-type transmission sensor 8 has a connecting ring 9 fixedly connected below the elastic element. The connecting ring 9 is connected to the inner ring of the connecting lug 6 on the top outer ring of the quantitative weighing barrel 3, thereby achieving a stable connection between the tension-type transmission sensors 8 and the quantitative weighing barrel 3 and ensuring the accuracy of weight measurement.

[0026] Referring to Figure 3, a viscous damper 10 is connected above the tension-type transmission sensor 8. When the discharge pipe 2 discharges a large amount of material for the first time, the material impact force is relatively large. The viscous damper 10 can effectively reduce the impact force on the quantitative weighing tank 3. The working principle of the viscous damper 10 is to use the damping effect of the internal viscous medium to consume the impact energy and suppress the shaking of the quantitative weighing tank 3. The ring 12 fixedly connected to its top is sleeved around the three connecting rods 7 on the outer wall of the discharge pipe 2 to achieve a stable connection with the discharge pipe 2.

[0027] Referring to Figure 3, a tension spring 11 is coaxially arranged around the periphery of the viscous damper 10. The two ends of the tension spring 11 are fixedly connected to the two ends of the viscous damper 10. The tension spring 11 mainly provides elastic tension and shares the tension force on the viscous damper 10. At the same time, the viscous damper 10 can attenuate the rebound oscillation force on the tension spring 11, so that the entire device can quickly recover to a stable state after being impacted.

[0028] Referring to Figure 3, a rotating wheel 13 is rotatably connected below the viscous damper 10, and a screw rod 14 is coaxially fixedly connected below the rotating wheel 13. The lower end of the screw rod 14 is threadedly connected to the top of the tension-type transmission sensor 8. By rotating the rotating wheel 13, the screw rod 14 rotates accordingly, thereby adjusting the distance between the viscous damper 10 and the tension-type transmission sensor 8. This design is crucial. In actual use, the distance between the two can be flexibly adjusted according to factors such as material characteristics and feeding speed to optimize the buffering effect and ensure the stability and accuracy of the feeding process.

[0029] In actual operation, the screw feeder 1 is started, and the organosilicon granules fall into the quantitative weighing bucket 3 through the discharge pipe 2. During this process, the viscous damper 10 and the tension spring 11 work together to effectively buffer the impact of the material and reduce the shaking of the quantitative weighing bucket 3, ensuring that the tension-type transmission sensor 8 can accurately measure the weight of the material. When the preset quantitative value is reached, the screw feeder 1 stops feeding, and at the same time, the vibration motor 5 starts to shake the material in the quantitative weighing bucket 3 to make the weighing data more accurate. Subsequently, the powder particle discharge control valve 4 is opened to discharge the quantitative organosilicon material, completing one quantitative feeding operation.

[0030] It should be noted that when the material weight is about to reach the preset quantitative value, the control system quickly issues an instruction to reduce the speed of the motor in the screw feeder 1, thereby slowing down the rotation speed of the screw. In this way, the conveying speed of the organosilicon particles is greatly reduced, achieving accurate feeding and effectively avoiding weighing errors caused by overfeeding.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
