Description

Technical Field

[0001] This utility model relates to the field of receiving hoppers, specifically a fully sealed rotating bulk cargo handling line receiving hopper. Background Technology

[0002] The receiving hopper is an important component of the bulk cargo handling line, mainly used for receiving and transferring bulk materials. The hopper is typically mounted on tires or rails, allowing it to move freely within the port area and making it suitable for various loading and unloading scenarios.

[0003] In the prior art, such as in the announcement number CN209522106U, a receiving hopper is disclosed, which includes an upward-opening hopper wall, a discharge port provided on the side of the hopper wall, an inclined portion of the hopper wall opposite to the discharge port, and a plurality of laterally extending wear-resistant strips provided on the inner surface of the portion of the hopper wall opposite to the discharge port.

[0004] Although the aforementioned patent describes a laterally extending wear-resistant strip on the inner surface of the hopper wall that can support and accumulate a certain height of aggregate to cover the inner surface of the hopper wall, thereby allowing the aggregate entering the receiving hopper to directly contact the accumulated aggregate and avoid direct friction between the aggregate and the hopper wall, protecting the hopper wall from wear and extending its service life, the material accumulates together during discharge, leading to difficulties in discharge and affecting material conveying. Furthermore, material may leak from the pipe connections, affecting the conveying process. Therefore, to address the above problems, a fully sealed rotating bulk cargo handling line receiving hopper is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as material accumulation during unloading leading to difficulties in unloading and affecting material conveying, and material leakage from pipeline connections also hindering conveying, this utility model proposes a fully sealed rotating bulk cargo handling line receiving hopper.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The fully sealed rotating bulk cargo handling line receiving hopper of this utility model includes a receiving hopper; the bottom of the receiving hopper is connected to a conical hopper, springs are symmetrically arranged at the four corners of the inner wall of the conical hopper and their ends are fixedly connected to the inner hopper, grooves are opened on both sides of the outer wall of the inner hopper and a vibration motor is installed inside, an annular cloth cover is set on the outer ring of the top of the inner hopper and fixed to the inner wall of the receiving hopper by a fixing ring, a discharge pipe is connected through the bottom of the conical hopper, an annular groove is opened on the inner wall of the discharge pipe and a connecting pipe is inserted inside, and an annular sealing ring that fits the annular groove is sleeved on the surface of the connecting pipe.

[0007] Preferably, the annular grooves are spaced apart along the axial direction of the discharge pipe, and the annular sealing ring is made of fluororubber and has a V-shaped cross-section.

[0008] Preferably, the conical bucket is made of wear-resistant alloy steel and has an anti-stick coating sprayed on its inner wall, and the bottom of the inner bucket has an inverted conical structure.

[0009] Preferably, the fixing ring is detachably connected to the inner wall of the receiving hopper by a bolt group, and the annular cloth cover is made of silicone and has an elastic closure at the edge.

[0010] Preferably, the springs are arranged in pairs with opposite spirals, and their free length is greater than one-third of the height of the conical bucket.

[0011] Preferably, the end of the connecting pipe is provided with a flange, which is adapted to the rotary sealing interface of the external conveying pipeline.

[0012] The advantages of this utility model are:

[0013] 1. This utility model, through the vibration structure design of the inner hopper and the vibrating motor, the vibrating motor in the groove of the inner hopper generates high-frequency vibration, and the springs are symmetrically arranged at the four corners to buffer the vibration energy and prevent structural fatigue, thereby realizing the function of continuous material feeding without accumulation and solving the problem of material blockage in traditional receiving hoppers. The vibrating motor drives the inner hopper to vibrate at high frequency in the conical hopper through the springs, so that the material slides evenly to the discharge pipe, improving the feeding efficiency.

[0014] 2. This utility model, through the matching and insertion design of the annular groove and the annular sealing ring, allows the V-shaped sealing ring to expand radially under pressure, forming a multi-level sealing surface with the annular groove. The fluororubber material is wear-resistant and has lasting elasticity, achieving a fully sealed connection between the discharge pipe and the connecting pipe, solving the problem of material leakage in bulk cargo transportation. The V-shaped fluororubber sealing ring expands under pressure during insertion, filling the gap of the annular groove, thus improving the sealing reliability. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-4 As shown, a fully sealed rotating bulk cargo handling line receiving hopper includes a receiving hopper 1; the bottom of the receiving hopper 1 is connected to a conical hopper 2, springs 3 are symmetrically arranged at the four corners of the inner wall of the conical hopper 2 and their ends are fixedly connected to an inner hopper 4, grooves 5 are opened on both sides of the outer wall of the inner hopper 4 and a vibration motor 6 is installed inside, an annular cloth cover 7 is set on the outer ring of the top of the inner hopper 4 and is fixed to the inner wall of the receiving hopper 1 by a fixing ring 8, and a discharge pipe 9 is connected through the bottom of the conical hopper 2. An annular groove 10 is opened on the inner wall of the discharge pipe 9 and a connecting pipe 11 is inserted inside, and an annular sealing ring 12 that is adapted to the annular groove 10 is sleeved on the surface of the connecting pipe 11.

[0023] During operation, after the material enters from the receiving hopper 1, it is guided into the inner hopper 4 by the annular cloth cover 7. The vibration motor 6 drives the inner hopper 4 to vibrate at high frequency in the conical hopper 2 through the spring 3 to prevent material accumulation. When discharging, the material slides down the conical hopper 2 to the discharge pipe 9. The connecting pipe 11 is sealed by inserting the annular sealing ring 12 into the annular groove 10 to prevent leakage. The vibration discharge combined with the sealing insertion structure achieves anti-clogging and zero leakage, improving discharge efficiency and sealing reliability.

[0024] Furthermore, the annular grooves 10 are spaced apart along the axial direction of the discharge pipe 9, and the annular sealing ring 12 is made of fluororubber and has a V-shaped cross-section.

[0025] During operation, the annular grooves 10 are spaced apart along the axial direction of the discharge pipe 9. The V-shaped fluororubber annular sealing ring 12 expands radially when compressed, forming a multi-level dynamic sealing interface. The V-shaped cross-section sealing ring adapts to pipeline vibration and deformation, and the corrosion resistance and elasticity of the fluororubber material enhance the long-term sealing performance.

[0026] Furthermore, the conical bucket 2 is made of wear-resistant alloy steel and has an anti-stick coating sprayed on the inner wall, and the bottom of the inner bucket 4 has an inverted conical structure;

[0027] During operation, the conical hopper 2 is made of wear-resistant alloy steel and coated with an anti-stick coating. The inverted conical structure at the bottom of the inner hopper 4 guides the material to fall in a concentrated manner. The anti-stick coating reduces material residue, and the inverted conical structure optimizes the material discharge path and reduces the risk of material accumulation.

[0028] Furthermore, the fixing ring 8 is detachably connected to the inner wall of the receiving hopper 1 by a bolt group, and the annular cloth cover 7 is made of silicone and has an elastic closure at the edge;

[0029] During operation, the fixing ring 8 is detachably connected to the inner wall of the receiving hopper 1 via bolt assembly. The edge of the silicone ring-shaped cloth cover 7 is elastically closed to adapt to the vibration displacement of the inner hopper 4. The detachable design simplifies the maintenance process, and the elastic closure dynamically seals dust, improving the working environment.

[0030] Furthermore, the springs 3 are arranged in pairs with opposite spirals, and their free length is greater than one-third of the height of the conical bucket 2;

[0031] During operation, the springs 3 are arranged in pairs with opposite spirals to counteract the lateral torque during vibration. The free length is adapted to the height of the conical bucket 2 to ensure uniform amplitude. The reverse spring group eliminates the risk of resonance, improves the efficiency of vibration energy transmission, and extends service life.

[0032] Furthermore, a flange is provided at the end of the connecting pipe 11, which is adapted to the rotary sealing interface of the external conveying pipeline.

[0033] During operation, the flange at the end of the connecting pipe 11 is fixed to the external rotating sealing interface with bolts to adapt to the multi-angle conveying requirements of the pipeline.

[0034] Working principle: After the material enters from the receiving hopper 1, it is guided into the inner hopper 4 by the annular cloth cover 7. The vibration motor 6 drives the inner hopper 4 to vibrate at high frequency in the conical hopper 2 through the spring 3 to prevent material accumulation. At the same time, the annular cloth cover 7 and the fixing ring 8 dynamically seal the dust. After the material slides down the conical hopper 2 to the discharge pipe 9, it is sealed by the annular groove 10 and the annular sealing ring 12 to prevent leakage. The flange at the end of the connecting pipe 11 is adapted to the external conveying pipe rotation interface to achieve multi-angle sealed conveying.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
