Description

Technical Field

[0001] This utility model belongs to the field of feed processing technology, specifically, it relates to a screening and dust removal device for feed processing. Background Technology

[0002] The feed formulation for Litopenaeus vannamei needs to be adjusted according to different growth stages. The protein content needs to reach about 30% during the juvenile stage and decrease to 25% to 28% during the adult stage. The core ingredients include fish meal, soybean meal, shrimp meal, etc., and premixes such as minerals and vitamins need to be added.

[0003] During feed processing, some raw materials contain dust, which needs to be removed before processing. Chinese utility model patent CN221620077U discloses a screening and dust removal device for feed processing. Feed falls into a screening box through a feed hopper. The feed first falls onto an upper inclined screen, where it is screened by a vibrator. The screened feed is then discharged through a corresponding discharge pipe. Simultaneously, as the feed falls from the feed hopper to the upper inclined screen, a blower can be activated to blow air into the screening box through an air duct, blowing dust from the feed into a dust collection box for collection. During this process, feed carried in the dust is filtered through a filter screen. Finally, the dust is discharged through a dust discharge pipe, achieving effective dust collection and preventing excessive dust generation at the discharge pipe, ensuring a good operating environment. A discharge pipe is connected to the bottom of the screening box, through which the finest feed screened by the lower inclined screen is discharged.

[0004] The aforementioned existing technology also has the following drawbacks: when screening and removing dust from raw materials, the raw materials added to the feed hopper will fall directly onto the screen below by gravity, causing the raw materials to pile up and become difficult to screen quickly, thus reducing the screening efficiency. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that when screening and removing dust from raw materials, the raw materials added to the feed hopper fall directly onto the screen below due to gravity, causing the raw materials to accumulate and become difficult to screen quickly, thus reducing screening efficiency, the present invention adopts the following technical solution.

[0007] A screening and dust removal device for feed processing includes a screening box, a storage hopper fixedly connected to one side of the upper end of the screening box, support legs fixedly connected to the four corners of the bottom of the screening box, multiple discharge ports provided on one side of the outer wall of the screening box, a screening component installed inside the screening box to screen the raw materials, and a feeding component installed on the top of the screening box to evenly drop the raw materials onto the screening component.

[0008] Preferably, a dust removal component is installed on the screening box to remove the dust raised during the raw material screening process.

[0009] Preferably, the screening assembly includes a screening screen and a vibrator. Multiple screening screens are detachably connected inside the screening box. Each screening screen has a discharge port on the side of the screening box near the bottom. A vibrator is installed on the bottom inner side of each screening screen, and the vibrator causes the screening screen to vibrate.

[0010] Preferably, the inner wall of the screening box near the bottom is fixedly connected with a guide plate, and a discharge pipe is installed at the center of the bottom of the screening box.

[0011] Preferably, the feeding assembly includes a transverse moving plate, limiting protrusions, meshing toothed plates, a drive motor, a drive gear, and a feeding groove. A through groove is provided near the bottom of the storage hopper. The transverse moving plate is slidably connected inside the through groove. Limiting protrusions are fixedly connected to the outer walls of both ends of the transverse moving plate. A meshing toothed plate is fixedly connected between the two limiting protrusions near the discharge port. A drive motor is detachably connected to the upper end of the screening box. A drive gear is detachably connected to the rotating end of the drive motor. The drive gear meshes with the meshing toothed plate. A feeding groove is provided at the upper end of the transverse moving plate. Trigger buttons are detachably connected to the opposite faces of the limiting protrusions near the meshing toothed plate.

[0012] Preferably, the dust removal assembly includes a filter box, a connecting pipe, a mounting block, an air inlet, and an air pump. The connecting pipe is detachably connected to the back of the screening box. The mounting block is detachably connected to the inner wall of the screening box above each screening screen. The mounting block is connected to and communicates with the connecting pipe. The filter box is detachably connected to and communicates with the outer wall of the connecting pipe. The air inlet of the air pump is detachably connected to the outer wall of the filter box. The mounting block is provided with multiple air inlets. An inclined surface is provided at the upper end of the mounting block near the outer edge of the inner wall of the screening box. The multiple air inlets are located on the inclined surface.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The feeding assembly, driven by a motor, rotates a gear, which in turn moves the transverse moving plate laterally. This causes the feeding trough to move laterally inside the storage hopper. The motor then reverses its rotation, causing the transverse moving plate to move in the opposite direction. This allows the feeding trough to change its position laterally inside the storage hopper, ensuring that the raw materials added to the storage hopper fall evenly onto the top screen plate, preventing the materials from piling up and reducing screening efficiency. During the transverse movement of the moving plate, pressing a button against the outer wall of the storage hopper causes the motor to rotate in the opposite direction, resulting in the transverse moving plate moving back and forth laterally.

[0015] 2. The dust removal components are designed to draw air through an air pump, creating suction at the air inlet. This allows the dust that flies up during the screening process to enter the filter box for filtration, thus removing dust from the raw materials. The inclined surface design reduces the amount of raw materials sucked in during the dust removal process, preventing waste. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] like Figure 1 As shown, this is a schematic diagram of a preferred embodiment of the present invention for a screening and dust removal device for feed processing. The screening and dust removal device for feed processing in this embodiment includes a screening box 100. A storage hopper 102 is fixedly connected to one side of the upper end of the screening box 100. Support legs 101 are fixedly connected to the four corners of the bottom of the screening box 100. A plurality of discharge ports 103 are provided on one outer wall of the screening box 100. In this embodiment, the raw materials to be screened are placed into the storage hopper 102 and enter the interior of the screening box 100 for screening. The screened raw materials are discharged outward through the discharge ports 103.

[0028] like Figure 2 As shown, this is a schematic diagram of the screening component structure in this embodiment. Multiple screening screens 104 are detachably connected inside the screening box 100. Each screening screen 104 has a discharge port 103 on one side of the screening box 100 near the bottom. A vibrator is installed on the inner bottom of each screening screen 104, causing the screening screen 104 to vibrate. Guide plates 106 are fixedly connected to the inner wall of the screening box 100 near the bottom. A discharge pipe is installed at the center of the bottom of the screening box 100. In this embodiment, the vibration of the screening screens 104 causes the raw materials to rise for filtration, separating dust from the raw materials during screening. The raw materials filtered by each screening screen 104 are discharged outward through the discharge port 103, thus enabling the raw materials to be classified by size.

[0029] It is worth noting that the screening screen 104 and the vibrator mentioned above are screening components in this embodiment. Screening components include, but are not limited to, the screening screen 104 and the vibrator. Any component that can screen raw materials can be applied to this embodiment.

[0030] like Figure 2 as well as Figure 3 As shown, this is a schematic diagram of the feeding assembly structure in this embodiment. A through groove 105 is provided near the bottom of the storage hopper 102. A transverse moving plate 200 is slidably connected inside the through groove 105. Limiting protrusions 201 are fixedly connected to the outer walls of both ends of the transverse moving plate 200. A meshing toothed plate 202 is fixedly connected between the two limiting protrusions 201 near the discharge port 103. A drive motor 203 is detachably connected to the upper end of the screening box 100. A drive gear 204 is detachably connected to the rotating end of the drive motor 203. The drive gear 204 meshes with the meshing toothed plate 202. The transverse moving plate 20... The upper end of the hopper 102 is provided with a feeding trough 206. In this embodiment, the drive motor 203 rotates to drive the drive gear 204 to rotate, which in turn enables the transverse moving plate 200 to move laterally through meshing. This allows the feeding trough 206 to move laterally inside the storage hopper 102. Then, the drive motor 203 rotates in the opposite direction, which enables the transverse moving plate 200 to move in the opposite direction. This allows the feeding trough 206 to change its position laterally inside the storage hopper 102, so that the raw materials added to the storage hopper 102 can fall evenly onto the surface of the uppermost screening screen plate 104, avoiding the accumulation of raw materials and the resulting reduction in screening efficiency.

[0031] It is worth noting that the aforementioned transverse moving plate 200, limiting protrusion 201, meshing toothed plate 202, drive motor 203, drive gear 204, and feeding trough 206 are the feeding components in this embodiment. The feeding components include, but are not limited to, the transverse moving plate 200, limiting protrusion 201, meshing toothed plate 202, drive motor 203, drive gear 204, and feeding trough 206. Any component that can make the raw material evenly distributed on the uppermost screening screen plate 104 can be applied to this embodiment.

[0032] like Figure 3 As shown, trigger buttons 205 are detachably connected to the opposite faces of the limiting protrusions 201 on both sides near the meshing tooth plate 202. In this embodiment, during the lateral movement of the transverse moving plate 200, the trigger button 205 contacts the outer wall of the storage hopper 102 and presses it, causing the drive motor 203 to rotate in the opposite direction, thereby enabling the transverse moving plate 200 to move laterally back and forth.

[0033] like Figure 4As shown, this is a schematic diagram of the dust removal component structure in this embodiment. A connecting pipe 301 is detachably connected to the back of the screening box 100. An installation block 302 is detachably connected to the inner wall of the screening box 100 above each screening screen 104. The installation block 302 is connected and communicates with the connecting pipe 301. A filter box 300 is detachably connected and communicates with the outer wall of the connecting pipe 301. The air inlet of the air pump 305 is detachably connected to the outer wall of the filter box 300. Multiple air inlets 304 are provided on the installation block 302. In this embodiment, the air pump 305 draws air to generate suction at the air inlets 304, so that the flying dust can enter the interior of the filter box 300 through the air inlets 304 for filtration during the screening process, thereby removing dust from the raw materials.

[0034] It is worth noting that the filter box 300, connecting pipe 301, mounting block 302, air inlet 304 and vacuum pump 305 mentioned above are dust removal components in this embodiment. The dust removal components include, but are not limited to, the filter box 300, connecting pipe 301, mounting block 302, air inlet 304 and vacuum pump 305. Any component that can collect dust from the raw materials can be used in this embodiment.

[0035] like Figure 4 As shown, an inclined surface 303 is provided at the upper end of the mounting block 302 near the outer edge of the inner wall of the screening box 100, and multiple air inlets 304 are provided on the inclined surface 303. In this embodiment, by setting the inclined surface 303, the intake of raw materials during the dust removal process can be reduced, thus avoiding waste of raw materials.

[0036] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
