Description

Technical Field

[0001] The utility model relates to the technical field of feed flow stabilization, in particular to a feed flow stabilization device for a roller press. Background Art

[0002] A roller press consists of two synchronously rotating squeeze rollers—one fixed and one movable. Material is fed from above the rollers and continuously drawn between them. Under high pressure, it forms a dense cake and is discharged from the bottom of the machine. The discharged cake contains a certain proportion of fine finished particles, while the unfinished particles have numerous cracks within them, improving the material's grindability. During operation, uneven material distribution in the feed zone and unstable feed rates can adversely affect the operation of the roller press, making it prone to roll deviation and stoppage.

[0003] For example, the "roller press feeding device" disclosed in Chinese utility model patent CN202023280138.1 discloses in its specification that the roller press needs to adjust the feed amount according to the actual working conditions during operation. Existing roller presses use belt conveyors to directly transport materials to the silo. During feeding, the materials tend to accumulate on the inner wall of the silo, resulting in eccentric feeding and inability to feed the roller press stably vertically. Uniform and continuous feeding is the key to roller press crushing. Unstable and uneven feeding will cause large fluctuations in the roller press gap, causing the equipment to trip and stop. The above patents can prove the defects of the existing technology.

[0004] Therefore, we made improvements to this and proposed a roller press feed stabilizing device. Summary of the Invention

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0028] Example

[0029] Please refer to Figure 1A feed flow stabilizing device for a roller press comprises a feed tray 1, a feed component 2 is provided on the top of the feed tray 1, an opening is provided on the edge of the feed tray 1, and a discharge component 3 is provided at the opening, a flow stabilizing component 4 and a buffer component 5 are provided at the bottom of the feed tray 1, the flow stabilizing component 4 is located at the center of the bottom of the feed tray 1, and the buffer component 5 is located at the edge of the bottom of the feed tray 1. The feed tray 1, the flow stabilizing component 4 and the discharge component 3 cooperate to ensure that the material is stably and continuously transported to the processing area of ​​the roller press, ensuring that the material forms a stable material column above the feed port of the roller press, so that the material can enter the roller press evenly and continuously, thereby improving the effective work of the roller press and preventing the roller press from having a biased roller phenomenon.

[0030] Further, such as Figure 1 As shown, the feed assembly 2 includes a feed plate 21 fixed on the top of the material tray 1, and first leak-proof plates 22 are fixed on both sides of the feed plate 21. Both ends of the first leak-proof plate 22 are chamfered.

[0031] The provision of the first leakage prevention plate 22 can effectively prevent the material from leaking from both sides of the feed plate 21 when passing through the feed plate 21 .

[0032] Further, such as Figure 1 and Figure 2 As shown, the discharge assembly 3 includes a discharge plate 34 fixed at the opening and second leak-proof plates 31 fixed on both sides of the discharge plate 34 . A guide plate 32 is fixed on the top of the discharge plate 34 , and the guide plate 32 is located between the two second leak-proof plates 31 .

[0033] The second leak-proof plate 31 , the guide plate 32 and the discharge plate 34 cooperate with each other to guide the materials so that the materials can accurately reach the feeding area of ​​the roller press.

[0034] Further, such as Figure 1 and Figure 2 As shown, a reinforcing rod 33 is fixedly connected between the guide plate 32 and the two second leakage-proof plates 31 , both ends of the guide plate 32 are chamfered, and the ends of the two second leakage-proof plates 31 are chamfered.

[0035] The reinforcing rod 33 can improve the structural strength of the guide plate 32 and the second anti-leakage plate 31 to prevent them from being deformed by being squeezed by the material.

[0036] Further, such as Figure 1 、 Figure 3 and Figure 4 As shown, the flow stabilizing component 4 includes a mounting plate 41 fixed at the bottom of the material tray 1 and a mounting cylinder 42 fixed inside the mounting plate 41, and also includes an electromagnet 44 fixed at the bottom inside the mounting cylinder 42 and a partition 45 fixed above the electromagnet 44, as well as a first spring 46 fixedly connected to the top of the partition 45 and an impact column 43 provided above the first spring 46.

[0037] After the electromagnet 44 is energized, it is magnetized, and a repulsive force is generated with the impact column 43, driving the impact column 43 to move upward. The impact column 43 impacts the bottom of the tray 1, generating vibration. After the electromagnet 44 is powered off, it is demagnetized, and the impact column 43 moves downward and resets. The electromagnet 44 is continuously energized and deenergized, so that the impact column 43 can continuously impact the bottom of the tray 1. Through continuous vibration, the material accumulated in the tray 1 moves toward the discharge plate 34, so that the material can be stably and continuously transported to the processing area of ​​the roller press.

[0038] Further, such as Figure 1 and Figure 5 As shown, the buffer assembly 5 includes four first support rods 52 fixedly arranged at the bottom of the material tray 1, a sleeve 51 is provided below the first support rod 52, a second support rod 53 is provided below the sleeve 51, a fixed plate 54 is fixedly provided at the bottom end of the second support rod 53, a first limiting plate 55 and a second limiting plate 56 are provided inside the sleeve 51, the second limiting plate 56 is located below the first limiting plate 55, the bottom end of the first support rod 52 passes through the sleeve 51 and is fixedly connected to the first limiting plate 55, the top end of the second support rod 53 passes through the sleeve 51 and is fixedly connected to the second limiting plate 56, and a second spring 57 is fixedly connected between the first limiting plate 55 and the second limiting plate 56.

[0039] When the impact column 43 continuously impacts the bottom of the material tray 1 to generate vibration, the second spring 57 can play a buffering and shock-absorbing role to prevent the vibration force from being transmitted to the fastener used to fix the fixing plate 54.

[0040] The use process of the roller press feed stabilizing device provided by the utility model is as follows:

[0041] The material enters the interior of the tray 1 through the feed plate 21 and accumulates inside the tray 1. The electromagnet 44 is controlled to be energized. After being energized, the electromagnet 44 is magnetized, generating a repulsive force with the impact column 43, driving the impact column 43 to move upward, and the impact column 43 impacts the bottom of the tray 1, generating vibration. After the electromagnet 44 is powered off, it is demagnetized, and the impact column 43 moves downward and resets. The electromagnet 44 is continuously energized and deenergized, so that the impact column 43 can continuously impact the bottom of the tray 1. Through continuous vibration, the material accumulated in the tray 1 moves toward the discharge plate 34, passes through the channel formed by the guide plate 32, and enters the processing area of ​​the roller press.
