Description
Technical Field
[0001] This utility model relates to the field of additive feeding and screening technology, and in particular to a feeding and screening device for compound additives. Background Technology
[0002] Compound additives refer to food additives made by combining two or more single-variety food additives according to certain process requirements and proportions through physical methods. Through compounding, additives can achieve functional effects that single additives cannot achieve. Feed screening equipment is used to screen and process various raw materials during the production process of compound additives. Different compound additives have strict requirements on the particle size of raw materials to ensure uniform mixing.
[0003] The existing technology has the following problems:
[0004] Existing multi-stage vibrating screening devices install a vibrating motor on each screening filter plate to ensure the screening effect. However, when facing different needs, the vibration frequency of the vibrating motor is different, which will cause the vibration of each screening filter plate to affect each other, resulting in the vibration being transmitted and interfering with each other, reducing the vibration effect and efficiency. Furthermore, when a large amount of raw materials enter, different materials will clump or agglomerate, causing blockage when they directly enter the vibrating screen, reducing the screening efficiency and effect. Utility Model Content
[0005] This invention provides a feeding and screening device for compound additives to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A feeding and screening device for compound additives includes several screening and filtering plates, which are parallel to each other. Supporting and damping columns are provided on the outer surfaces of the screening and filtering plates. A feeding conveying device is provided above the rear end of the supporting and damping columns. A vibration motor is provided at the rear end of each screening and filtering plate.
[0008] A further improvement of this utility model is that: the supporting damping column includes a supporting feed block, the supporting feed block is located on the rear side of the uppermost screening filter plate, two parallel supporting columns are provided on both the left and right sides of the screening filter plate, a supporting base is fixedly connected to the bottom of the supporting column, a shock-absorbing groove is opened on the side of the supporting column near the screening filter plate, and a shock-absorbing support assembly is provided inside the two parallel shock-absorbing grooves, and the bottom of the supporting feed block is fixedly connected to the top of the two rear supporting columns.
[0009] A further improvement of this utility model is that the support base is made of rubber.
[0010] A further improvement of this utility model is that: the shock-absorbing support assembly includes several support movable blocks, which are parallel to each other and slidably connected inside the rear shock-absorbing groove; several frame support blocks are slidably connected inside the front shock-absorbing groove; vibration anti-transmission springs are fixedly connected to the opposite sides of two adjacent support movable blocks and two adjacent frame support blocks; support springs are fixedly connected to the bottom ends of the lowest support movable block and frame support blocks; the bottom ends of the support springs are fixedly connected to the top of the support base; and the support movable blocks and frame support blocks located on the same horizontal plane are fixedly connected to the outer surface of the screening filter plate on the same horizontal plane.
[0011] A further improvement of this utility model is that the diameter of the vibration-damping spring wire is smaller than that of the support spring wire, and the length of the front support spring is smaller than that of the rear support spring.
[0012] A further improvement of the present invention is that the feeding conveying device includes a conveying component, the conveying component is shaped like a ☐, the front end of the horizontal outer surface of the conveying component is fixedly connected to the inside of the supporting feeding block, and a raw material container is fixedly connected to the lower part of the inclined outer surface of the conveying component, and supporting side columns are fixedly connected to both the left and right sides of the raw material container.
[0013] A further improvement of the present invention is that the conveying assembly includes a conveying pipe, a conveying spiral column is provided on the inner side of the conveying pipe in an inclined direction, a drive shaft is fixedly connected to the top of the conveying spiral column, the top of the drive shaft extends to the outer side of the top of the conveying pipe, the top of the drive shaft is fixedly connected to the output shaft of the drive motor, the outer surface of the conveying spiral column is in close contact with the inner side of the conveying pipe, and the inner side of the conveying pipe is connected to the raw material container.
[0014] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0015] 1. This utility model provides a feeding and screening device for compound additives. The support column can support the screening filter plates during vibration screening, and the vibration of each screening filter plate is limited to a specific range by the shock-absorbing support component. When the vibration motor on each screening filter plate vibrates at different frequencies, the shock-absorbing support component can effectively buffer and isolate the vibration, reduce the vibration transmission interference between each screening filter plate, and the rubber material of the support base also helps to further absorb the vibration, thereby improving the independence and stability of the vibration of each screening filter plate, ensuring the vibration screening effect, and improving the vibration efficiency.
[0016] 2. This utility model provides a feeding and screening device for compound additives. When faced with a large amount of raw materials, the raw materials first enter the raw material container through the conveying pipe and the conveying spiral column. The raw materials are then uniformly conveyed from the conveying pipe to the screening filter plate. During the conveying process, the rotation of the conveying spiral column plays a role in stirring and loosening the raw materials, which can effectively prevent the raw materials from clumping or agglomerating. This avoids the blockage caused by the raw materials directly entering the vibrating screen, thereby improving the screening efficiency and effect. Attached Figure Description

Detailed Implementation
[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:
[0024] like Figure 1-5 As shown, this utility model provides a feeding and screening device for compound additives, including several screening and filtering plates 1, which are parallel to each other. Supporting and damping columns 2 are provided on the outer surfaces of the screening and filtering plates 1. A feeding and conveying device 3 is provided above the rear end of the supporting and damping columns 2. In the operation of the compound additive feeding and screening device, the screening and filtering plates 1 are used to perform multi-stage screening of raw materials, the supporting and damping columns 2 support the screening and filtering plates 1 and buffer their vibration, and the feeding and conveying device 3 conveys the raw materials to the screening and filtering plates 1 for screening.
[0025] The vibration motor and the screening filter plate 1 are existing technologies and will not be explained here.
[0026] like Figure 2 As shown, this utility model provides a technical solution: Preferably, the supporting shock-absorbing column 2 includes a supporting feed block 21, which is located on the rear side of the uppermost screening filter plate 1. Two parallel supporting columns 23 are provided on both the left and right sides of the screening filter plate 1. A supporting base 25 is fixedly connected to the bottom end of the supporting column 23. A shock-absorbing groove 22 is provided on the side of the supporting column 23 near the screening filter plate 1. A shock-absorbing support assembly 24 is provided inside the two parallel shock-absorbing grooves 22. The bottom end of the supporting feed block 21 is fixedly connected to the top of the two rear supporting columns 23.
[0027] When the equipment is working, the support feed block 21 in the support damping column 2 provides guidance for the raw material to enter the screening filter plate 1, the support column 23 supports the entire structure, the support base 25 at the bottom enhances stability, and the shock-absorbing groove 22 on the support column 23, together with the internal shock-absorbing support component 24, buffers the vibration of the screening filter plate 1 to ensure the stability of the screening process.
[0028] like Figure 2 As shown, this utility model provides a technical solution: preferably, the support base 25 is made of rubber, which can further absorb vibration.
[0029] like Figure 3 As shown, this utility model provides a technical solution: Preferably, the shock-absorbing support assembly 24 includes a plurality of support moving blocks 241, which are parallel vertically and slidably connected inside the rear shock-absorbing groove 22. A plurality of frame support blocks 244 are slidably connected inside the front shock-absorbing groove 22. Vibration anti-transmission springs 242 are fixedly connected to the opposite sides of two adjacent support moving blocks 241 and two adjacent frame support blocks 244. Support springs 243 are fixedly connected to the bottom ends of the lowest support moving block 241 and the frame support blocks 244. The bottom ends of the support springs 243 are fixedly connected to the top end of the support base 25. The support moving blocks 241 and the frame support blocks 244 located on the same horizontal plane are fixedly connected to the outer surface of the screening filter plate 1 on the same horizontal plane.
[0030] like Figure 3 As shown, this utility model provides a technical solution: preferably, the wire diameter of the vibration anti-transmission spring 242 is smaller than the wire diameter of the support spring 243, and the length of the front support spring 243 is smaller than that of the rear support spring 243.
[0031] When the screening filter plate 1 vibrates, the support moving block 241 and the frame support block 244 on the same horizontal plane drive the screening filter plate 1, which is fixedly connected to it, to move. The vertically parallel support moving block 241 slides in the shock-absorbing slide groove 22. The adjacent support moving block 241 and the frame support block 244 are connected by the vibration anti-transmission spring 242. The lowest support moving block 241 and the frame support block 244 are connected to the support base 25 by the support spring 243. Because the wire diameter of the vibration anti-transmission spring 242 is smaller than that of the support spring 243, and the length of the front support spring 243 is smaller than that of the rear support spring 243, the screening filter plate 1 will be tilted, which facilitates screening and output. These components work together to effectively buffer and limit the vibration of the screening filter plate 1, reduce vibration transmission interference, and ensure stable screening.
[0032] like Figure 4 As shown, the present invention provides a technical solution: preferably, the feeding conveying device 3 includes a conveying component 32, the conveying component 32 is shaped like a ☐, the front end of the outer surface of the conveying component 32 in the horizontal direction is fixedly connected to the inside of the supporting feeding block 21, and a raw material container 33 is fixedly connected to the lower part of the outer surface of the conveying component 32 in the inclined direction, and supporting side columns 34 are fixedly connected to the left and right sides of the raw material container 33.
[0033] The raw materials are first loaded into the raw material container 33. The O-shaped conveying component 32 of the feeding conveying device 3 provides the raw materials in its inclined direction by relying on the raw material container 33. It is connected to the supporting feeding block 21 at the front end in the horizontal direction and is kept stable by the supporting side columns 34 fixedly connected on its left and right sides, thereby conveying the raw materials to the subsequent screening filter plate 1 for screening.
[0034] like Figure 5 As shown, this utility model provides a technical solution: Preferably, the conveying assembly 32 includes a conveying pipe 323, a conveying spiral column 322 is provided on the inner side of the conveying pipe 323 in an inclined direction, a drive shaft 321 is fixedly connected to the top of the conveying spiral column 322, the top of the drive shaft 321 extends to the outer side of the top of the conveying pipe 323, the top of the drive shaft 321 is fixedly connected to the output shaft of the drive motor 31, the outer surface of the conveying spiral column 322 is in close contact with the inner side of the conveying pipe 323, and the inner side of the conveying pipe 323 communicates with the raw material container 33.
[0035] The drive motor 31 starts, driving the drive shaft 321 connected to its output shaft to rotate, which in turn causes the conveying spiral column 322 fixed at the top of the drive shaft 321 to rotate inside the conveying pipe 323. The raw material enters the conveying pipe 323 from the raw material container 33 connected to the conveying pipe 323, and is conveyed along the conveying pipe 323 towards the screening filter plate 1 under the push of the conveying spiral column 322, providing raw materials for subsequent screening work.
[0036] The working principle of a feeding and screening device for compound additives will be explained in detail below.
[0037] like Figure 1-5 As shown, the compound additive raw materials are loaded into the raw material container 33 for screening. The drive motor 31 is started, and the drive shaft 321 drives the conveying spiral column 322 to rotate in the conveying pipe 323. The raw materials enter the conveying pipe 323 from the raw material container 33 and are conveyed towards the screening filter plate 1 under the push of the spiral column. At the same time, the rotation of the conveying spiral column 322 stirs and loosens the raw materials to prevent agglomeration. When the raw materials reach the screening filter plate 1, the vibration motor at the rear end of the screening filter plate 1 is started. Under the action of the support damping column 2, the screening filter plate 1 vibrates and screens the raw materials. Raw materials of different particle sizes are screened and separated by each level of the screening filter plate 1. The support column 23, the shock-absorbing slide 22, the shock-absorbing support component 24, etc. work together to buffer the vibration, reduce interference, and ensure the screening effect.
[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
