Description

Technical Field

[0001] This utility model belongs to the technical field of particle screening devices, and in particular relates to a particle screening device for raw material processing. Background Technology

[0002] In the processing of raw materials for food flavorings, screening is a crucial pretreatment step. The purpose of screening is to effectively separate the mixed raw materials according to particle size in order to obtain products with specific particle sizes that meet the process requirements.

[0003] However, existing particle screening devices often experience filter clogging during the screening process, especially with raw materials that have slightly higher moisture content, high powder content, or irregular shapes. These materials are prone to getting stuck in the screen holes during vibration, particularly on the lower fine screen of a multi-layer screen.

[0004] Blockage not only significantly reduces the effective screening area and hinders the passage of qualified fine materials through the screen, but also causes materials to accumulate on the screen surface, affecting subsequent material flow and grading accuracy. Frequent shutdowns to clean the screen severely impact production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a sieving device for raw material processing. By setting up a sieving assembly, specifically by starting a vibrating motor, a telescopic rod, and a spring, the sieving box can float within a certain range, causing the raw material to jump, tumble, and move on the inclined coarse and fine filter screens. Large particles intercepted by the coarse filter screen are discharged from the right-side outlet, medium-sized particles intercepted by the fine filter screen are discharged from the front outlet, and fine particles screened by the fine filter screen are discharged from the rear outlet by relying on the inclined inner wall at the bottom. This solves the problem that existing sieving devices often experience filter screen clogging during the sieving process, which affects production efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a sieving device for raw material processing, comprising a sieving box and a sieving assembly. The top of the sieving box is fixedly connected to a feed inlet, and the front, back, and right sides of the sieving box are all fixedly connected to discharge outlets. The bottom inner wall of the sieving box is inclined towards the discharge outlet on the back side. The sieving assembly is installed inside the sieving box and is used for sieving raw materials. The sieving assembly includes: A coarse filter screen is installed inside the sieve box at the top, and the coarse filter screen is inclined towards the discharge port located on the right side; A fine filter screen is installed inside the lower part of the sieve box, and the fine filter screen is inclined towards the discharge port located in front; Four support legs are fixedly connected to the four corners of the bottom of the sieve box. A telescopic rod is fixedly connected to the bottom of each support leg. A spring is sleeved on the outer surface of the telescopic rod. A support base is fixedly connected to the bottom of the telescopic rod. A vibrating motor is fixedly connected to the bottom of the sieve box.

[0007] Furthermore, a rubber pad is fixedly connected to the bottom of the support base.

[0008] Furthermore, several screen rods are fixedly connected to the inner wall of the feed inlet.

[0009] Furthermore, two slide rails are fixedly connected to the left and right sides of the inner wall of the sieve box, and sliders are fixedly connected to the left and right sides of the coarse and fine filter screens, with the inner wall of the sliders slidably connected to the outer surface of the slide rails.

[0010] Furthermore, guide plates are fixedly connected to the bottom inner wall of the sieve box and the side near the top of the fine filter screen.

[0011] Furthermore, a baffle is fixedly connected to the top of the guide plate, and both the coarse and fine filters are solid on the right side of the baffle.

[0012] This utility model has the following beneficial effects: 1. This utility model, by setting up a particle screening assembly, specifically by starting a vibration motor, a telescopic rod, and a spring, allows the particle screening box to float within a certain range, causing the raw material to jump, tumble, and move on the inclined coarse and fine filter screens. Large particles intercepted by the coarse filter screen are discharged from the right-side outlet, medium-sized particles intercepted by the fine filter screen are discharged from the front outlet, and fine particles screened by the fine filter screen are discharged from the back outlet by relying on the inclined inner wall at the bottom. This effectively avoids the raw material clogging the filter screen and improves production efficiency.

[0013] 2. This utility model improves the utilization rate and screening uniformity of the coarse and fine filters by setting a guide plate and a baffle. Specifically, the guide plate can guide the raw material to move towards the discharge port, avoiding the accumulation of raw material on the right side of the sieve box. The baffle and the solid parts of the coarse and fine filters are set to prevent the raw material from falling into the ineffective area and causing the raw material to stagnate.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figures 1-5 As shown, this utility model has the following three specific embodiments.

[0020] Example 1 This utility model relates to a particle screening device for raw material processing, comprising a particle screening box 1 and a particle screening assembly 2. The top of the particle screening box 1 is fixedly connected to a feed inlet 11, and the front, back, and right sides of the particle screening box 1 are all fixedly connected to discharge outlets 12. The bottom inner wall of the particle screening box 1 is inclined towards the discharge outlet 12 on the back side. The particle screening assembly 2 is installed inside the particle screening box 1 and is used for screening raw materials. The particle screening assembly 2 includes: Coarse filter screen 21 is installed inside the upper part of the sieve box 1, and the coarse filter screen 21 is inclined towards the discharge port 12 located on the right side; Fine filter screen 211 is installed inside the lower part of the sieve box 1, and the fine filter screen 211 is inclined towards the discharge port 12 located on the front. Four support legs 22 are fixedly connected to the four corners of the bottom of the sieve box 1. A telescopic rod 221 is fixedly connected to the bottom of the support leg 22. A spring 222 is sleeved on the outer surface of the telescopic rod 221. A support seat 223 is fixedly connected to the bottom of the telescopic rod 221. Vibration motor 23 is fixedly connected to the bottom of the sieve box 1.

[0021] like Figures 1-2 As shown, by setting up the particle screening assembly 2, specifically by starting the vibration motor 23, the telescopic rod 221 and the spring 222, the particle screening box 1 can float within a certain range, causing the raw material to jump, roll and move on the inclined coarse filter screen 21 and fine filter screen 211. Large particles intercepted by the coarse filter screen 21 are sent out from the right discharge port 12, medium particles intercepted by the fine filter screen 211 are sent out from the front discharge port 12, and fine particles screened by the fine filter screen 211 are sent out from the back discharge port 12 by relying on the inclined inner wall at the bottom. This effectively avoids the raw material clogging the filter screen and improves production efficiency.

[0022] A rubber pad 224 is fixedly connected to the bottom of the support base 223.

[0023] Rubber pad 224 enhances the friction between the device and the ground, preventing the position of the sieve box 1 from shifting during vibration, while also isolating the vibration transmission from the ground and reducing the operating noise of the device.

[0024] Example 2 The difference from Embodiment 1 is that this embodiment discloses a screen rod 111 and a slide rail 212: Several screen rods 111 are fixedly connected to the inner wall of the feed inlet 11.

[0025] Two slide rails 212 are fixedly connected to the left and right sides of the inner wall of the sieve box 1. Slider 213 is fixedly connected to the left and right sides of the coarse filter screen 21 and the fine filter screen 211. The inner wall of the slider 213 is slidably connected to the outer surface of the slide rail 212.

[0026] like Figures 3-4 As shown, the screen rod 111 can prevent large impurities from entering the sieve box 1, and at the same time control the flow rate to prevent the feed inlet 11 from being blocked; when it is necessary to clean or replace the coarse filter screen 21 or the fine filter screen 211, the coarse filter screen 211 or the fine filter screen 211 can be pulled out by sliding the slide rail 212 and the slider 213.

[0027] Example 3 The difference from Embodiment 2 is that this embodiment discloses a guide vane 24 and a baffle 241: A guide plate 24 is fixedly connected to the bottom inner wall of the sieve box 1 and the side near the top of the fine filter screen 211.

[0028] A baffle 241 is fixedly connected to the top of the baffle 24. The coarse filter 21 and the fine filter 211 located on the right side of the baffle 241 are both solid.

[0029] like Figure 5As shown, by setting the guide plate 24 and the baffle 241, specifically the guide plate 24 can guide the raw material to move towards the discharge port 12, avoiding the accumulation of raw material on the right side of the sieve box 1. The baffle 241 and the solid parts of the coarse filter screen 21 and the fine filter screen 211 are set to prevent the raw material from falling into the ineffective area, which would cause the raw material to stagnate, thus improving the utilization rate and screening uniformity of the coarse filter screen 21 and the fine filter screen 211.

[0030] A specific application of this embodiment is as follows: During use, the raw material is introduced through the feed inlet 11. The screen rod 111 prevents large impurities from entering the sieve box 1, while controlling the flow rate to prevent clogging of the feed inlet 11. The vibration motor 23 is started, and the telescopic rod 221 and spring 222 allow the sieve box 1 to float within a certain range, thereby transmitting vibration energy to the entire sieve box 1 and its internal coarse and fine filter screens 211. This causes the raw material to jump, tumble, and move violently on the inclined coarse and fine filter screens 211. Large particles intercepted by the coarse filter screen 21 are discharged from the right-side outlet 12, medium-sized particles intercepted by the fine filter screen 211 are discharged from the front outlet 12, and fine particles screened by the fine filter screen 211 are discharged according to... The material is discharged from the rear outlet 12 by the inclined inner wall at the bottom. During the screening process, the guide plate 24 can guide the material to move towards the outlet 12, avoiding the accumulation of material on the right side of the sieve box 1. The solid parts of the baffle 241, coarse filter screen 21 and fine filter screen 211 prevent the material from falling into the ineffective area and causing material retention. The rubber pad 224 at the bottom of the support base 223 enhances the friction between the device and the ground, preventing the position of the sieve box 1 from shifting during vibration, while isolating the vibration transmission with the ground and reducing the operating noise of the device. When it is necessary to clean or replace the coarse filter screen 21 or the fine filter screen 211, the coarse filter screen 21 or the fine filter screen 211 can be pulled out by the sliding cooperation of the slide rail 212 and the slider 213.
