Description

Technical Field

[0001] This application relates to the field of sieving technology, specifically to a vibrating sieving device for glutinous rice flour. Background Technology

[0002] The vibrating screen filter for glutinous rice flour is a high-precision fine particle screening device. It uses a vibrating motor to drive the screen surface to make three-dimensional motion (such as spiral jumping forward), forcing the material to complete fine classification on the screen.

[0003] Its typical structure includes a vibrating motor, a screen box, multiple layers of screens (1-5 layers) and a support frame, which can simultaneously separate materials of 2-6 particle sizes, with a minimum screening accuracy of 500 mesh (0.028mm).

[0004] For example, patent CN220195464U discloses a vibrating rice flour sieving device. This patent improves the sieving effect of the device when sieving powder in rice by installing a vibrating sieving component. It can drive the rice to flow in conjunction with vibration. The powder in the highly fluid rice will settle downward under the vibration force, and the tiny powder will flow downward through the gap between the adaptable baffle and the conveyor mesh, while the rice will be blocked. This makes the sieving of rice flour convenient and highly practical.

[0005] In the actual sieving process of glutinous rice flour, if there are a large number of particles (critical particles) in the glutinous rice flour that are close to the size of the sieve holes, these particles are easy to get stuck in the sieve holes, causing the sieve to become clogged, resulting in a reduction in the effective flow area, a decrease in the processing capacity, and the need for frequent machine shutdowns for cleaning, which increases the labor intensity.

[0006] Therefore, it is necessary to provide a vibrating screen filter for glutinous rice flour to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] like Figures 1-2 As shown, this application provides a vibrating screen filter for glutinous rice flour. The vibrating screen filter is installed in a glutinous rice flour production plant and is mainly used for screening glutinous rice flour. Specifically, the vibrating screen filter includes a support 1, a feeding hopper 2 fixedly installed at the upper end of the support 1 for introducing glutinous rice flour, and an outlet 5 fixedly installed at the bottom end of the support 1 for discharging the screened glutinous rice flour.

[0035] Meanwhile, a screening mechanism 3 is provided on the support 1 at the position between the feed hopper 2 and the outlet 5. The screening mechanism 3 is used to perform vibration screening of glutinous rice flour.

[0036] The screening mechanism 3 includes mounting plates 30 fixedly installed on both sides of the support 1, and multiple sets of springs 31 are fixedly installed on the mounting plates 30. A fixed frame 34 is fixedly installed between the multiple sets of springs 31, and the fixed frame 34 is inclined. A vibration motor 33 is fixedly installed on one side of the fixed frame 34. When the vibration motor 33 is started, the fixed frame 34 can be driven to vibrate on the support 1, thereby providing power for vibrating screening.

[0037] Meanwhile, a screen 35 is fixedly installed inside the fixed frame 34. The screen 35 is inclined along with the fixed frame 34. When the glutinous rice flour is guided to the surface of the screen 35, the inclined screen 35 can use gravity to promote the flow of the glutinous rice flour on the screen 35. During the flow, the sieving operation is carried out by vibration. In this way, the glutinous rice flour with a larger aperture will automatically move to the lower end along the inclined screen 35 during the vibration.

[0038] Meanwhile, a guide pipe 36 is fixedly installed on the other side of the fixed frame 34. The guide pipe 36 is located at the lower end of the screen 35 so that glutinous rice flour with a larger aperture can be automatically introduced into the guide pipe 36 during vibration and then discharged along the guide pipe 36.

[0039] It should be noted that the screen 35 is located at the bottom of the feed hopper 2, so that the glutinous rice flour can be smoothly fed into the surface of the screen 35 through the feed hopper 2. The screen 35 is located directly above the outlet 5 so that the sifted glutinous rice flour can be smoothly discharged for use.

[0040] When glutinous rice flour is fed onto the surface of screen 35 through hopper 2, vibration motor 33 can be started to drive screen 35 to vibrate on support 1 through fixed frame 34. At this time, glutinous rice flour is subjected to vibration force and gravity on screen 35. Glutinous rice flour with a hole diameter smaller than that of screen 35 falls freely through screen 35 to the lower outlet 5 for discharge, while glutinous rice flour with a hole diameter larger than that of screen 35 remains on screen 35 and gradually moves towards the lower end of screen 35 as screen 35 vibrates until it reaches guide pipe 36, where it falls into the collection area below along guide pipe 36.

[0041] To prevent glutinous rice flour from getting stuck in the gaps of the sieve (35mm mesh) and causing blockage, such as... Figures 2-3 As shown, a clearing mechanism 4 is provided at both ends of the fixed frame 34. The clearing mechanism 4 cleans the holes on the screen 35, thereby achieving the clearing effect of the screen 35.

[0042] The unblocking mechanism 4 includes a fixed frame 40 fixedly installed at both ends of the fixed frame 34, and a cylinder 41 fixedly installed on the fixed frame 40. A fixed rod 42 is fixedly installed at the output end of the cylinder 41, and the fixed rod 42 is installed along the lower end of the screen 35, so that starting the cylinder 41 can push the fixed rod 42 to move along the lower end of the screen 35.

[0043] In order to clean the holes on the screen 35, a mounting bracket 43 is fixedly installed at the other end of the fixing rod 42, and a rotating roller 44 is rotatably installed between the mounting brackets 43. The rotating roller 44 is used to fit against the lower surface of the screen 35, so that the starting cylinder 41 can push the rotating roller 44 to move along the lower end of the screen 35 through the fixing rod 42.

[0044] Meanwhile, multiple sets of bristles 45 are fixedly installed on the rotating roller 44. The bristles 45 match the holes on the screen 35 so that when the cylinder 41 pushes the rotating roller 44 to move along the lower end of the screen 35, the bristles 45 on the rotating roller 44 can enter the holes of the screen 35 to clean the glutinous rice powder blocked in the holes, thereby achieving the effect of unblocking the screen 35.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
