Description

Technical Field

[0001] This utility model relates to the field of raw material crushing and collection technology in the biodegradable new materials industry, specifically to a quick-disassembly hopper suitable for collecting ultrafine straw raw materials. Background Technology

[0002] High-fiber raw materials, such as relatively clean straw and lignocellulose that do not contain plant roots or stems, can be processed using ultrafine grinding technology to release active ingredients and optimize their physicochemical properties. This is a core technological path for developing functional products and achieving efficient resource utilization. However, achieving ultrafine grinding presents the following technical challenges:

[0003] 1. Low unloading efficiency: Traditional material buckets are mostly made of stainless steel, and the bucket opening adopts a fixed structure or a single opening design. When unloading, it is necessary to lift and disassemble with one hand or rely on auxiliary tools, which is time-consuming, laborious, easy to tip over, and easy to leave material residue.

[0004] 2. Dust pollution risk: The particle size of ultrafine plant materials is small (≤10μm). Ordinary material buckets are not well sealed, which can easily lead to dust leakage during unloading, endangering the health of operators and polluting the environment.

[0005] 3. Difficult to clean and maintain: Ultrafine powder easily adheres to the inner wall of the material bucket, and traditional structures are difficult to clean thoroughly, which can easily lead to cross-contamination or affect product quality.

[0006] 4. Poor compatibility: It cannot be adapted to various equipment interfaces, resulting in high production line modification costs. Utility Model Content

[0007] To address the existing shortcomings, a fully sealed, quick-assembly, and easy-to-clean ultrafine plant material collection hopper has been developed. This hopper achieves efficient unloading and zero dust leakage, and is compatible with ultrafine grinding, post-processing grading, and dust removal equipment. It aims to solve the technical pain points of traditional collection devices in ultrafine powder processing, such as low unloading efficiency, high risk of dust leakage, and difficulty in cleaning the equipment. It is suitable for ultrafine grinding equipment, air classifiers, and reverse-flushing dust removal equipment.

[0008] To solve the above problems, the technical solution adopted by this utility model includes: a storage bin with a feed inlet; and a magnetic component disposed on the feed inlet.

[0009] A feeding pipe, the first end of which is connected to the feed inlet; a second magnetic component, which is disposed on the first end of the feeding pipe and is used to be attracted to the first magnetic component; and a sealing component, which is located between the first end of the feeding pipe and the feed inlet.

[0010] Preferably, the surface of the connection between the first end of the conveying pipe and the inlet is provided with multi-layered grooves that cooperate with the sealing element.

[0011] Preferably, the sealing element includes a sealing gasket and multiple layers of sealing protrusions, the multiple layers of sealing protrusions being coaxially disposed on the sealing gasket, and the multiple layers of sealing protrusions being installed one-to-one in the multiple grooves at the connection between the feed inlet and the first end of the conveying pipe.

[0012] Preferably, the sealing gasket has a flange at the connection between the feed inlet and the first end of the feed pipe for covering the outer layer of the first end of the feed pipe.

[0013] Preferably, the storage silo is equipped with a visualization window for real-time monitoring of the material level.

[0014] Preferably, it also includes an auxiliary unloading component, which includes a negative pressure component for reducing the flying of fine powder raw materials and a vibrating component for promoting the flow of fine powder raw materials. The negative pressure component is installed on the feed inlet, and the vibrating component is installed on the side wall of the storage silo.

[0015] Beneficial effects:

[0016] 1. Improved unloading efficiency: Single disassembly / installation time ≤ 5 seconds, which is more than 80% more efficient than the traditional method, and there is no risk of tipping over.

[0017] 2. Reduced dust leakage rate: Through double sealing and negative pressure unloading, the dust leakage rate is ≤0.01mg / m³, which meets the occupational health standard (GBZ 2.1-2019).

[0018] 3. Optimized residual rate: The residual powder in the barrel after unloading is ≤0.1%, reducing material waste. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Combination Figures 1 to 4 This embodiment illustrates a quick-release material bin, including a storage bin 1 with a feed inlet 11; a magnetic component 111 disposed on the feed inlet 11; a conveying pipe 2 with its first end port 21 connected to the feed inlet 11; a magnetic component 211 disposed on the first end port 21 of the conveying pipe for adsorption with the magnetic component 111; and a sealing component 3 located between the first end port 21 of the conveying pipe and the feed inlet 11.

[0026] It should be noted that the storage bin 1 is made of 316 stainless steel with a wall thickness of 2mm and a pressure resistance of ≥0.5MPa. The inner wall of the storage bin 1 is coated with Teflon (PTFE) nano-coating to reduce powder adhesion and make the residue easy to clean with a single rinse.

[0027] The mating surfaces of the feed inlet 11 and the first end port 21 of the conveying pipe adopt a quick-release flange structure, using internationally common specifications of quick-release flanges, which are compatible with different models of crushers, classifiers and back-flushing dust removal equipment. The feed inlet 11 and the first end port 21 of the conveying pipe are fitted with quick-release clamps.

[0028] The feed inlet 11 has an annular groove along its circumference, and a magnetic element 111 is embedded in the annular groove. The magnetic element is a magnet. The first end port 21 of the conveying pipe has an annular groove along its circumference, and a magnetic element 211 with the opposite polarity to the magnetic element 111 is embedded in the annular mounting groove. The feed inlet 11 and the first end port 21 of the output pipe are pre-positioned by the magnetic attraction of the magnetic element 111 and the magnetic element 211. The connection or disassembly is achieved by a clamp fitted at the joint of the feed inlet 11 and the first end port 21 of the conveying pipe.

[0029] Combination Figure 2 and Figure 3 The surface of the first end of the conveying pipe where it connects to the inlet 11 is provided with multi-layered grooves 4 that cooperate with the sealing element 3.

[0030] It should be noted that the surfaces of the feed inlet 11 and the first end of the conveying pipe 21 are respectively provided with multi-layered annular grooves 4 that radiate outward from the center, which help to cooperate with the sealing element 3 to prevent raw material leakage.

[0031] Combination Figure 4 As shown, the sealing element 3 includes a sealing gasket 31 and a multi-layer sealing protrusion 32. The multi-layer sealing protrusion 32 is coaxially disposed on the sealing gasket 31, and the multi-layer sealing protrusion 32 is installed one-to-one in the multi-layer groove 4 at the connection between the feed inlet 11 and the first end of the conveying pipe.

[0032] It should be noted that the multi-layered sealing protrusions 32 are installed one-to-one in the multi-layered grooves 4 at the connection between the feed inlet 11 and the first end port 21 of the conveying pipe. This is to prevent the material from leaking outward through the joint between the feed inlet 11 and the first end port 21 of the conveying pipe when conveying ultra-fine materials.

[0033] The sealing gasket 31 has a flange 33 at the connection between the inlet 11 and the first end of the conveying pipe for covering the outer layer of the first end of the conveying pipe.

[0034] The storage silo is equipped with a visualization window for real-time monitoring of material level.

[0035] It should be noted that the storage silo 1 is equipped with a visualization window 5, which is an explosion-proof, high-transparency polycarbonate window for real-time monitoring of material level. The visualization window is made of explosion-proof polycarbonate sheet with a thickness of 5-8mm, and the surface of the sheet is hardened to form a wear-resistant layer with a thickness of ≥50μm.

[0036] It also includes an auxiliary unloading component 6, which includes a negative pressure component 61 for reducing the flying of fine powder raw materials and a vibration component 62 for promoting the flow of fine powder raw materials. The negative pressure component 61 is installed on the feed inlet 11, and the vibration component 62 is installed on the side wall of the storage bin 1.

[0037] It should be noted that the negative pressure component 61 is an integrated micro vacuum pump interface. During unloading, the negative pressure is connected through a quick-connect pipe to reduce dust flying and the residual rate is ≤0.1%. The vibration component 62 is a pneumatic turbine vibrator. The pneumatic turbine vibrator adopts a quick-connect air intake and vibrates the storage bin 1 during unloading to promote powder flow and avoid bridging.

[0038] Working principle:

[0039] When raw materials need to be stored, the feed inlet 11 and the output pipe 21 are pre-positioned by magnetic component 111 and magnetic component 211, and quickly tightened by clamps fitted at the joint of the feed inlet 11 and the output pipe 21. The sealing component 3 includes a sealing gasket 31 and sealing protrusions 32. Multiple layers of the sealing protrusions 32 are coaxially arranged on the sealing gasket 31, and multiple layers of the sealing protrusions 32 are installed one-to-one in the multi-layered grooves 4 at the connection between the feed inlet 11 and the first end of the conveying pipe 21. This is to prevent material leakage from the joint of the feed inlet 11 and the first end of the conveying pipe 21 when conveying ultra-fine materials. This helps to improve the sealing performance of fine powder raw materials when unloading into the storage bin 1. After the raw materials are stored, the storage bin 1 and the conveying pipe 2 can be quickly separated by simply opening the clamps.

[0040] The auxiliary unloading component 6 includes a negative pressure component 61 to reduce the flying of fine powder raw materials and a vibrating component 62 to promote the flow of fine powder raw materials. The storage port integrates a micro vacuum pump interface. During unloading, a quick-connect pipe is used to connect the negative pressure suction to reduce dust flying, with a residual rate of ≤0.1%. The vibrating component 62 is installed on the side wall of the conveying hopper. The vibrating component 62 is a pneumatic turbine vibrator. The pneumatic turbine vibrator uses a quick-connect air intake. During unloading, it vibrates the above-mentioned storage hopper 1 to promote powder flow and avoid bridging.

[0041] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
