Abstract
Description
Technical Field
[0001] This utility model relates to the field of coffee bean storage technology, specifically an anti-static, large-capacity intermediate buffer silo. Background Technology
[0002] Coffee beans are the seeds inside the fruit of the coffee tree (coffee cherry). After processing such as removing the pulp, drying, and hulling, they become green beans. Roasting then brings out their unique flavor and aroma, and they are the core raw material used for grinding and brewing coffee. Intermediate buffer silos are temporary storage containers set between continuous production processes. They are mainly used to act as a buffer zone during material transportation. In the process of large-scale, in-depth processing of coffee beans (such as roasting, grinding, and packaging), intermediate buffer silos are key equipment to ensure the continuous and stable operation of the production line. They are used to temporarily store coffee beans that have been processed by previous processes (such as washing and sorting) and to provide a stable supply for subsequent processes.
[0003] When coffee beans enter the intermediate buffer silo, the high-speed friction and collision between the dry coffee beans and the pipes or other beans during the conveying process can easily lead to the generation of static charge. Static electricity can cause coffee beans to clump together and affect flow, so a conductive mesh (or grounding mesh) needs to be installed inside the silo to conduct static charge to the ground in a timely manner. However, due to the scouring and impact of materials during long-term use, the conductive mesh may experience surface wear, wire fatigue, or even breakage, resulting in a decrease in its structural strength and conductivity continuity. To efficiently replace and maintain the conductive mesh, an anti-static, large-capacity intermediate buffer silo is now provided, which can eliminate the drawbacks of existing equipment. Utility Model Content
[0004] The purpose of this invention is to provide an anti-static, large-capacity intermediate buffer silo to solve the problems in the background art.

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] In one embodiment, such as Figures 1-6 As shown, an anti-static, large-capacity intermediate buffer silo includes a silo body 1, a feed hopper 3 fixedly connected to the top of the silo body 1, a central guide cylinder 5 installed inside the silo body 1, multiple sets of mesh frames 4 vertically and equidistantly arranged on the outer wall of the central guide cylinder 5, multiple sets of mesh frames 4 arranged in each set of mesh frames 4, all of which extend to the outside of the silo body 1 and are slidably connected to the silo body 1, and all of which are in contact with the outer wall of the central guide cylinder 5. A conductive mesh is fixedly connected to the inner wall of the mesh frame 4. Multiple support columns 6 are fixedly and equidistantly connected to the bottom of the silo body 1. Multiple sets of discharge ports are vertically and equidistantly opened on the outer wall of the central guide cylinder 5. A discharge port 7 is integrally formed at the bottom of the silo body 1. An electric valve is installed inside the discharge port 7. The electric valve is electrically connected to an external controller through a wire. A replacement mechanism for easy disassembly and replacement of the mesh frame 4 is provided on the mesh frame 4. The replacement mechanism includes: a sealing plate 206 fixedly connected to the outer wall of the end of the mesh frame 4 away from the central guide tube 5. The sealing plate 206 is located on the outside of the silo body 1 and is in contact with the outer wall of the silo body 1. In this embodiment, when in use, coffee beans are fed into the inner cavity of the central guide tube 5 through the feed hopper 3. At this time, the central guide tube 5 can guide the coffee beans to fall smoothly, reduce the impact, and avoid local accumulation. During this process, when the coffee beans come into contact with the outer wall of the conductive mesh, the conductive mesh can absorb the static charge attached to the coffee beans. At the same time, the static charge can be transferred to the ground through the replacement mechanism. In this way, the static charge can be transferred in real time, effectively preventing the coffee beans from generating static electricity during storage. When it is necessary to discharge the coffee beans, the electric valve is opened by the external controller, so that the coffee beans can be conveniently discharged through the discharge port 7. When the conductive mesh needs to be replaced, the mesh frame 4 can be easily disassembled and replaced through the replacement mechanism. Then, the above operation is reversed to easily install the new mesh frame 4, thereby realizing convenient disassembly and maintenance of the conductive mesh. In one embodiment, such as Figures 3-6 As shown, the replacement mechanism also includes a limiting component disposed on the central guide tube 5; The limiting component includes: multiple sets of support plates 207 that are vertically and equidistantly fixedly connected to the outer wall of the central guide tube 5. The multiple sets of support plates 207 are all fixedly connected to the main body 1 of the hopper. The multiple sets of support plates 207 correspond to multiple sets of mesh frames 4 respectively. Multiple sets of support plates 207 are provided in one set of support plates 207. The multiple support plates 207 are intersected with the multiple mesh frames 4 respectively. The support plate 207 is provided with a support component for guiding and supporting the wire frame 4; The frame 4 is provided with a positioning component for sliding positioning of the frame 4; The sealing plate 206 is provided with a conductive component for conducting static electricity; The sealing plate 206 is provided with a locking component for locking and fixing the sealing plate 206; The support assembly includes two guide plates 209 symmetrically fixedly connected to the outer wall of the support plate 207. A linear groove is provided at the junction of the wire frame 4 and the guide plate 209 for the guide plate 209 to slide. Through the cooperation of the limiting assembly and the support assembly, the wire frame 4 can be moved and limited and stably supported. In one embodiment, such as Figures 3-6 As shown, the positioning component includes: a limiting baffle 205 that is slidably connected inside the mesh frame 4, a positioning block 201 that is fixedly connected to the top of the limiting baffle 205, the outer wall of the top of the positioning block 201 being hemispherical, and the positioning block 201 penetrating through the mesh frame 4 to the interior of the hopper body 1. A reset component is provided on the limit baffle 205; The reset assembly includes a spring 204 disposed at the bottom of the limiting baffle 205. One end of the spring 204 contacts the lower surface of the limiting baffle 205, and the other end of the spring 204 contacts the inner wall of the mesh frame 4. Through the cooperation of the positioning assembly and the reset assembly, the mesh frame 4 can be easily locked and positioned.
[0023] In one embodiment, such as Figures 2-5 As shown, the conductive component includes: two second conductive sheets 2010 symmetrically fixedly connected to one end of the sealing pressure plate 206 near the hopper body 1; a mesh frame 4 located between the two second conductive sheets 2010; both second conductive sheets 2010 are electrically connected to the conductive mesh via wires; and a first conductive sheet 208 is provided at the end of each of the two second conductive sheets 2010 away from the sealing pressure plate 206. The first conductive sheet 208 is fixedly connected to the hopper body 1 and grounded via wires. Through the cooperation of the first conductive sheet 208 and the second conductive sheet 2010, static charge can be transferred to the ground. In this way, static charge can be effectively prevented from being generated in coffee beans during storage by real-time transfer. In one embodiment, such as Figures 1-6As shown, the locking assembly includes: a mating plate 203 fixedly connected to the bottom end of the sealing pressure plate 206. The mating plate 203 is in contact with the outer wall of the hopper body 1. A bolt 202 is provided at the end of the mating plate 203 away from the hopper body 1. The bolt 202 passes through the mating plate 203 to the interior of the hopper body 1. The mating plate 203 is threadedly connected to the hopper body 1. Through the mutual cooperation of the bolt 202 and the mating plate 203, the sealing pressure plate 206 can be conveniently locked and fixed.
[0024] The above embodiment discloses an anti-static large-capacity intermediate buffer hopper. In use, coffee beans are fed into the inner cavity of the central guide cylinder 5 through the feed hopper 3. At this time, the central guide cylinder 5 can guide the coffee beans to fall smoothly, reduce impact, and avoid local accumulation. During this process, when the coffee beans come into contact with the outer wall of the conductive mesh, the conductive mesh absorbs the static charge attached to the coffee beans and transfers it to the second conductive sheet 2010 through the wire. At the same time, the first conductive sheet 208 can transfer the static charge on the second conductive sheet 2010 to the ground through the wire. In this way, the static charge can be transferred in real time, effectively preventing the coffee beans from generating static electricity during storage. When it is necessary to discharge the coffee beans, the electric valve is opened by the external controller, so that the coffee beans can be conveniently discharged through the discharge port 7. When the conductive mesh needs to be replaced, the bolt 202 is rotated with a tool to separate it from the main body 1 of the hopper, thereby releasing the locking and fixing of the connecting plate 203. Then, the sealing pressure plate 206 is pulled to move the connecting plate 203 horizontally. At this time, the mesh frame 4 is driven by the sealing pressure plate 206, which drives the positioning block 201 to move synchronously and separate from the outer wall of the central guide cylinder 5. At the same time, the positioning block 201 is limited and blocked by the main body 1 of the hopper, which pushes the limiting baffle 205 to slide along the inner wall of the mesh frame 4. At this time, the limiting baffle 205 is retracted by the moving compression spring 204, thereby realizing the convenient disassembly and replacement of the mesh frame 4.
[0025] The above operations are then reversed to facilitate the installation of the new wire frame 4, thereby enabling convenient disassembly and maintenance of the conductive wire.
[0026] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
