Description

Technical Field

[0001] This application relates to the field of storage equipment, and more particularly to a storage silo. Background Technology

[0002] During the production, storage, and transportation of rubber and plastic granules, metallic impurities can easily be mixed in, which can affect the quality and performance of rubber and plastic products.

[0003] In related technologies, the main methods for removing metal impurities include the following: (1) manual screening: separating impurities by visual inspection or sieve; (2) magnetic separation equipment: setting up an independent magnetic separator in the production line; (3) vibrating screening: separating impurities by vibrating screen.

[0004] Regarding the aforementioned technologies, manual screening is inefficient and prone to missed detections; magnetic separation equipment occupies a large space and cannot cover the discharge stage of storage tanks; vibrating screens have poor adsorption effect on metal impurities and are prone to secondary pollution of rubber or plastic particles; there is an urgent need for a method that balances efficiency and impurity removal effect. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a storage bin.

[0006] The storage silo provided in this application adopts the following technical solution: A storage bin includes a mounting frame and a bin body, the bin body being mounted on the mounting frame and having an inlet and an outlet. The storage bin also includes an adsorption assembly, which includes a plurality of magnetic rods disposed on the inner wall of the outlet.

[0007] By adopting the above technical solution, the magnetic rod is magnetic. When the product particles flow out of the discharge port, they will come into contact with or approach the magnetic rod. The magnetic rod can adsorb the metal impurities mixed in the product particles, thereby completing the impurity removal in the discharge stage. This saves the cost and space of the magnetic separation equipment, realizes continuous automatic impurity removal, is more efficient and less prone to missed detection. The magnetic adsorption of the magnetic rod has a stronger ability to capture metal impurities, taking into account both the efficiency and effect of removing metal impurities.

[0008] Optionally, several of the magnetic rods are arranged side by side at intervals, and the adsorption assembly further includes a connecting rod that connects all the magnetic rods.

[0009] By adopting the above technical solution, when the magnetic rods are arranged side by side at intervals, gaps are formed between adjacent magnetic rods to allow product particles to pass through. During the flow process, the product particles will contact the surface of the magnetic rods or pass through the gaps, increasing the contact opportunities with the magnetic rods and improving the adsorption probability of metal impurities. On the other hand, the connecting rod connects all the magnetic rods into a whole. When a lot of impurities are adsorbed on the surface of the magnetic rods and need to be cleaned, all the magnetic rods can be removed at once by the connecting rod. After cleaning, they can be reinstalled back into the discharge port as a whole, which improves the convenience of disassembling and assembling the magnetic rods.

[0010] Optionally, the hopper body has two sets of opposing limiting posts arranged on the inner wall of the discharge port, and the two sets of limiting posts respectively abut against the side of the magnetic rod near the outside of the hopper body.

[0011] By adopting the above technical solution, the limiting post can limit and fix the magnetic rod, preventing the magnetic rod from tilting or falling off the outside of the bin due to the impact force when the product particles flow out. This improves the stability of the magnetic rod's position in the discharge port, ensuring that the magnetic rod always maintains an effective adsorption range for the flowing product particles, and effectively maintains the removal effect of metal impurities.

[0012] Optionally, the number of limiting posts in each group is at least two.

[0013] By adopting the above technical solution, multiple limiting posts effectively support and limit the magnetic rod, reducing the probability of the magnetic rod tilting due to uneven force (such as impact from product particles on one side), and further improving the installation stability of the magnetic rod.

[0014] Optionally, the length of some of the magnetic rods gradually increases from both sides toward the middle.

[0015] By adopting the above technical solution, the cross-section of the discharge port is circular, and the flow rate in the middle area is usually greater. The middle magnetic rod is made longer so that it is closer to the diameter of the discharge port cross-section, while the magnetic rods on both sides are shorter to adapt to the chord length of the corresponding position of the discharge port cross-section. This achieves high coverage of the discharge port cross-section, reduces dead angles in impurity removal, and effectively improves the comprehensiveness of impurity removal for metals.

[0016] Optionally, at least one of the magnetic rods has a groove at both ends, and a compression spring is provided in the groove of the magnetic rod. The end of the compression spring away from the bottom of the groove is fixedly connected to an abutment post partially embedded in the groove. An abutment block is provided on the inner wall of the discharge port, and a groove that mates with the abutment post is provided on the side of the abutment block away from the outside of the chamber.

[0017] By adopting the above technical solution, the magnetic rod is pushed into the discharge port, the abutting post contacts the abutting block and compresses the compression spring. When the abutting post moves to the groove position, the compression spring resets and pushes the abutting post into the groove, which improves the convenience of installing the magnetic rod.

[0018] Optionally, the thickness of the abutment block gradually increases from the side closest to the outside of the compartment to the side furthest from the outside of the compartment.

[0019] By adopting the above technical solution, the side of the abutment block closer to the outside of the bin is thinner, and the side farther from the outside of the bin is thicker, forming an inclined guide surface. When installing the magnetic rod, the abutment post will first contact the thinner side of the abutment block. As the magnetic rod is pushed into the inside of the bin, the abutment post slides along the inclined surface, and the compression spring is gradually compressed and finally locked into the groove. This reduces the probability of jamming or damage caused by hard contact between the abutment post and the abutment block, and improves the smoothness of installing the magnetic rod.

[0020] Optionally, the abutment block is further provided with a guide groove on the inner wall side away from the discharge port, and the guide groove extends in a direction close to or away from the outside of the chamber.

[0021] By adopting the above technical solution, the abutment post slides along the guide groove towards the groove direction, which reduces the probability of the abutment post shifting to both sides along the sliding direction and improves the accuracy of the abutment post embedding into the groove.

[0022] Optionally, the hopper includes a storage section and a guide discharge section fixedly connected to the storage section near the discharge port. The inner diameter of the guide discharge section gradually decreases from the side away from the discharge port to the side near the discharge port.

[0023] By adopting the above technical solution, the inner diameter of the guide discharge section gradually decreases, which plays a role in converging and guiding the product particles, causing the product particles in the storage section to flow towards the discharge port in a concentrated manner, reducing the residue of product particles on the inner wall of the silo, and improving the smoothness of discharge.

[0024] Optionally, the container body is provided with a viewing window.

[0025] By adopting the above technical solution, operators can directly observe the storage volume of product particles in the silo through the viewing window and promptly understand whether additional feeding is needed; they can also observe whether there are any abnormalities such as impurity accumulation or clumping in the silo, which facilitates timely handling and improves the ease of use of the storage silo.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The magnetic rod adsorbs the metal impurities mixed in the product particles, and the impurity removal is completed in the discharge stage, which takes into account both the efficiency and effect of removing metal impurities. 2. The magnetic rods are arranged side by side at intervals, and gaps are formed between adjacent magnetic rods to allow product particles to pass through, which increases the contact opportunities with the magnetic rods and improves the probability of adsorption of metal impurities; 3. The connecting rod connects all the magnetic rods into a whole. When the magnetic rods need to be cleaned, all the magnetic rods can be removed at once, cleaned, and then reinstalled as a whole back into the discharge port, which improves the convenience of disassembling and assembling the magnetic rods.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a storage bin.

[0034] Example 1 Reference Figure 1 and Figure 2 The storage silo includes a mounting frame 1, a silo body 2, and an adsorption assembly 3. The silo body 2 is mounted on the mounting frame 1 for storing rubber or plastic granules. The adsorption assembly 3 is mounted on the silo body 2 to adsorb metal particle impurities from the rubber or plastic granules.

[0035] Reference Figure 1 The hopper 2 includes a storage section 21 and a guide discharge section 22. The storage section 21 and the guide discharge section 22 are fixedly connected and cooperate to form a storage cavity for storing product particles. The storage section 21 has a feed inlet 211 on the side away from the guide discharge section 22. A plurality of mounting blocks 212 are fixedly connected to the storage section 21. The mounting blocks 212 are distributed circumferentially around the storage section 21 and are fixedly connected to the mounting frame 1 by bolts to fix the hopper 2 onto the mounting frame 1.

[0036] Reference Figure 1 The guide discharge section 22 has a discharge port 221 on the side away from the storage section 21 for unloading by workers. The inner diameter of the guide discharge section 22 gradually decreases from the side away from the discharge port 221 to the side closer to the discharge port 221, so that the product particles accumulate at the discharge port 221. A discharge valve 222 is also installed on the side of the guide discharge section 22 near the discharge port 221 to control the discharge of product particles. Both the storage section 21 and the guide discharge section 22 are provided with viewing windows 23 to allow workers to observe the amount and status of product particles in the storage bin.

[0037] Reference Figure 2 The adsorption component 3 includes magnetic rods 31 and connecting rods 32. In Embodiment 1 of this application, there are three magnetic rods 31, which are arranged side by side with intervals between them, forming a gap between adjacent magnetic rods 31 for product particles to pass through. The length of the magnetic rods 31 located on both sides is shorter than the length of the magnetic rod 31 located in the middle, so as to adapt to the circular cross-section of the discharge port 221. There are two connecting rods 32, which are arranged side by side and fixedly connected to all the magnetic rods 31 to connect the multiple magnetic rods 31 into a whole.

[0038] Reference Figure 2 Two sets of limiting posts 223 are fixedly connected to the inner wall of the discharge port 221. The two sets of limiting posts 223 are arranged opposite to each other on the inner wall of the discharge port 221 and abut against the side of the magnetic rod 31 near the outside of the chamber 2 to support the adsorption assembly 3. The number of limiting posts 223 in each set is at least two. In Embodiment 1 of this application, the number of limiting posts 223 in each set is two. The two limiting posts 223 in the same set are arranged side by side with intervals to improve the stability of the adsorption assembly 3 installation.

[0039] The implementation principle of Example 1 is as follows: During the process of embedding the adsorption component 3 into the chamber 2 from the discharge port 221, the limiting post 223 passes through the gap between two adjacent magnetic rods 31. Then, the adsorption component 3 is rotated 90°. At this time, the magnetic rod 31 abuts against the side of the limiting post 223 near the inside of the chamber 2, thus completing the installation of the adsorption component 3. The product particles are guided by the inclined side wall of the guide discharge part 22 and gather at the discharge port 221. When the discharge valve 222 is opened, the product particles leave the chamber 2 after passing through the gap between the magnetic rods 31. At this time, the magnetic rods 31 adsorb the metal impurities mixed in the product particles, and remove impurities at the same time as discharge.

[0040] Example 2 Reference Figure 3 and Figure 4The difference between this embodiment and Embodiment 1 lies in the installation method of the adsorption component 3 and the inner wall of the discharge port 221. At least one magnetic rod 31 has embedding grooves 311 at both ends. In Embodiment 2 of this application, all three magnetic rods 31 have embedding grooves 311 at both ends. A compression spring 312 is embedded in the embedding groove 311 of the magnetic rod 31, with one end of the compression spring 312 abutting against the bottom of the embedding groove 311. The other end of the compression spring 312 is fixedly connected to an abutment post 313, with the side of the abutment post 313 near the compression spring 312 embedded in the embedding groove 311.

[0041] Reference Figure 3 and Figure 4 Abutment blocks 224, corresponding one-to-one with the abutment posts 313, are fixedly connected to the inner wall of the discharge port 221. The thickness of the abutment blocks 224 gradually increases from the side near the outside of the chamber 2 to the side away from the outside of the chamber 2, so that during the installation of the magnetic rod 31, the abutment posts 313 gradually retract into the embedding grooves 311 under the pressure of the abutment blocks 224. To prevent the abutment posts 313 from shifting during the sliding of the magnetic rod 31 into the chamber 2 at the discharge port 221, the abutment blocks 224 have guide grooves 2241. The guide grooves 2241 extend in a direction near or away from the outside of the chamber 2 to limit the sliding direction of the abutment posts 313. The side of the abutment block 224 away from the outside of the chamber 2 has a groove 2242, and the side of the groove 2242 away from the inner wall of the discharge port 221 penetrates the abutment block 224. The abutment post 313 extends to one side outside the embedding groove 311 and abuts against the bottom of the groove 2242 to install the magnetic rod 31 on the inner wall of the discharge port 221.

[0042] The implementation principle of Example 2 is as follows: the end of the abutment post 313 extending outside the embedding groove 311 abuts against the bottom of the guide groove 2241, and then the adsorption component 3 is pushed to slide along the guide groove 2241 into the chamber 2. When the side of the abutment post 313 extending outside the embedding groove 311 passes through the groove 2242 and abuts against the bottom of the groove 2242, the installation of the adsorption component 3 is completed. The product particles are guided by the inclined side wall of the guide discharge part 22 and gather at the discharge port 221. When the discharge valve 222 is opened, the product particles leave the chamber 2 after passing through the gap between the magnetic rods 31. At this time, the magnetic rods 31 adsorb the metal impurities mixed in the product particles, and the impurity removal is achieved at the same time as the discharge.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
