Description

Technical Field

[0001] This utility model relates to the field of steel-lined rubber chutes, and in particular to an anti-clogging device for steel-lined rubber chutes. Background Technology

[0002] Steel-lined rubber chutes are specialized conveying devices that combine the strength of steel with the wear resistance, corrosion resistance, and shock absorption properties of rubber. The working principle of steel-lined rubber chutes is similar to that of ordinary chutes; both utilize the material's own gravity to slide down an inclined chute for transport. Within the inclined chute, the material is subjected to the component of gravity, causing it to slide downwards. When the frictional resistance between the chute bottom plate and the material is less than the component of gravity, the material begins to slide. The chute's inclination angle controls the material's conveying speed and direction, ensuring stable and continuous transport to the target location.

[0003] In practical use, the fluidity of the material itself is the key factor affecting chute blockage in steel-lined rubber chutes. When the material has excessive moisture content, high viscosity, or uneven particle size distribution, it is easy for material to accumulate in the chute. In particular, when the material contains a large number of fine, sticky particles, these particles tend to accumulate at the bottom of the chute and right-angled edges, forming material traps and causing blockage.

[0004] If the chute angle is not designed properly, such as being too small, it will cause the material to fall unevenly, easily leading to material accumulation at impact points and corners. Furthermore, the cross-sectional shape of the chute, the design of its corners, and the length of the path will also affect the flowability of the material. For example, the angle between the straight sides of a rectangular cross-section can easily form a dihedral obstruction zone, resulting in poor operation; while a corner with straight sides can easily become clogged due to a sudden change in the running trajectory.

[0005] The lining material in steel-lined rubber chutes wears down over time, increasing friction between the material and the chute wall and further affecting material flowability. Especially when the lining material lacks sufficient high-temperature performance or impact resistance, it is more easily worn or broken by the material, thus exacerbating blockages.

[0006] The main objective of this invention is to provide a steel-lined rubber chute anti-clogging device, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A steel-lined rubber chute anti-clogging device includes a rubber chute body and a material inlet, wherein the material inlet is located on the upper part of the side wall of the rubber chute body.

[0009] The rear end of the feed port is connected to an anti-clogging pipe via a connecting flange, and a secondary pipe is provided on the upper side wall of the anti-clogging pipe. The outer end of the secondary pipe is connected to a sealing plug, and the outer end of the sealing plug is provided with a sealing pipe. The interior of the sealing pipe is provided with a telescopic hose, and the outer end of the sealing pipe is connected to an air pump, which is connected to the telescopic hose.

[0010] The inner end of the telescopic hose is provided with a rigid conical head, which is obliquely aligned with the connection between the anti-clogging pipe and the material inlet. The side wall of the secondary pipe is connected to a connecting screw pipe through a connecting branch pipe, and a pressure relief valve is connected through the connecting screw pipe. An instrument is provided between the pressure relief valve and one of the connecting screw pipes.

[0011] In a further preferred embodiment, the anti-clogging pipe, connecting flange, and secondary pipe are designed as a single unit, with the secondary pipe inclined and its axis aligned with the intersection of the anti-clogging pipe and the material inlet. A sealing ring is provided at the connection between the material inlet and the anti-clogging pipe.

[0012] In a further preferred embodiment, the sealing plug includes a flange and an inner convex tube. The inner convex tube is located at the inner end of the flange and is inserted into the secondary pipe. The sealing plug is fixed to the secondary pipe by bolts, and multiple sealing rings are fitted on the inner convex tube. The sealing plug and the sealing pipe are designed as an integral part.

[0013] In a further preferred embodiment, the flexible hose includes a rigid port and a telescopic tube. The rigid port is located at the end of the telescopic tube and is connected to a sealed pipe. Multiple sealing rings are provided at the connection between the rigid port and the sealed pipe. The rigid port is connected to the interface of the air pump.

[0014] In a further preferred embodiment, the connecting branch pipe is fixed on the secondary pipe, the connecting branch pipe and the connecting screw pipe are connected by threads, and a sealing ring is provided at the connection between the connecting branch pipe and the connecting screw pipe. The connecting screw pipe is sealed and fixed on both ends of the pressure relief valve.

[0015] In a further preferred embodiment, the instrument is a pressure gauge, which is connected to the anti-clogging pipe and the auxiliary pipe through a connecting solenoid and a connecting branch pipe to detect the internal pressure of the anti-clogging pipe;

[0016] In a further preferred embodiment, the rigid conical head and the telescopic hose are designed as a single unit, and the lower end of the rigid conical head is an air nozzle, and the cross-section of the rigid conical head is designed in a conical shape.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] When the air pump is started, the telescopic hose drives the rigid conical head toward the anti-clogging pipe port. The rigid conical head is aligned at an angle with the connection between the anti-clogging pipe and the material inlet, forming a high-pressure airflow, which effectively prevents material from accumulating and clogging at the pipe connection, ensuring smooth material flow.

[0019] The inclined design of the secondary pipes and the sealing plugs, along with their integrated connection with the anti-clogging pipes, enhance the sealing and stability of the pipeline, further preventing material leakage and blockage.

[0020] The combined use of pressure relief mechanisms and instruments enables real-time monitoring of the pressure inside the anti-clogging pipeline, ensuring it remains within the normal range. This avoids problems such as pipeline rupture or material blockage caused by excessive pressure, thus improving the safety and reliability of the equipment.

[0021] All components of the equipment are tightly connected and leak-free, with a secure connection between the rigid conical head and the telescopic hose, ensuring the overall performance and stability of the equipment and extending its service life. Furthermore, regular inspection and maintenance of the equipment guarantee its long-term stable operation. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 - Figure 4 As shown, a steel-lined rubber chute anti-clogging device is provided, which consists of a rubber chute body 1 and a material outlet 2, wherein the material outlet 2 is located at the upper end of the side wall of the rubber chute body 1.

[0029] The rear end of the feed inlet 2 is connected to the anti-clogging pipe 3 via a connecting flange 4. A secondary pipe 5 is located on the upper side wall of the anti-clogging pipe 3. A sealing plug 6 is connected to the outer end of the secondary pipe 5, and a sealing pipe 7 is located at the outer end of the sealing plug 6. A flexible hose 9 is installed inside the sealing pipe 7, and an air pump 8 is connected to the outer end of the sealing pipe 7. The air pump 8 is connected to the flexible hose 9.

[0030] The inner end of the flexible hose 9 is equipped with a rigid conical head 10, which is angled towards the connection between the anti-clogging pipe 3 and the feed port 2. The side wall of the secondary pipe 5 is connected to the connecting screw pipe 12 via the connecting branch pipe 11, and is connected to the pressure relief valve 13 via the connecting screw pipe 12. An instrument 14 is installed between the pressure relief valve 13 and one of the connecting screw pipes 12. When the air pump 8 is activated, it extends and retracts the flexible hose 9, thereby driving the rigid conical head 10 to move toward the port of the anti-clogging pipe 3, preventing blockage at the port of the anti-clogging pipe 3.

[0031] The anti-clogging pipe 3, connecting flange 4, and secondary pipe 5 are designed as a single unit. The secondary pipe 5 is inclined, with its axis aligned with the intersection of the anti-clogging pipe 3 and the material inlet 2. A sealing ring is provided at the connection between the material inlet 2 and the anti-clogging pipe 3.

[0032] The sealing plug 6 consists of a flange and an inner convex tube. The inner convex tube is located at the inner end of the flange and is inserted into the secondary pipe 5. The sealing plug 6 is fixed to the secondary pipe 5 with bolts, and multiple sealing rings are fitted on the inner convex tube. The sealing plug 6 and the sealing pipe 7 are designed as an integrated unit.

[0033] The flexible hose 9 consists of a rigid port and a telescopic tube. The rigid port is located at the end of the telescopic tube and is connected to the sealed pipe 7. Multiple sealing rings are provided at the connection between the rigid port and the sealed pipe 7. The rigid port is connected to the interface of the air pump 8.

[0034] The connecting branch pipe 11 is fixed to the secondary pipe 5, and the connecting branch pipe 11 and the connecting threaded pipe 12 are connected by threads. A sealing ring is provided at the connection between the connecting branch pipe 11 and the connecting threaded pipe 12, and the connecting threaded pipe 12 is sealed and fixed on both ends of the pressure relief valve 13.

[0035] Instrument 14 is a pressure gauge, which is connected to the anti-clogging pipe 3 and the secondary pipe 5 through the connecting solenoid 12 and the connecting branch pipe 11 to detect the internal pressure of the anti-clogging pipe 3.

[0036] The rigid conical head 10 and the telescopic hose 9 are integrated into one unit. The lower end of the rigid conical head 10 is an air nozzle with a conical cross-section to form a high-pressure airflow inside the anti-clogging pipe 3, thereby effectively preventing material blockage.

[0037] Ensure all components of the anti-clogging device for the steel-lined rubber chute are correctly installed and connected. Check that the rubber chute body 1 and the inlet 2 are intact. Confirm that the anti-clogging pipe 3, secondary pipe 5, sealing plug 6, sealing pipe 7, telescopic hose 9, air pump 8, and other components are tightly connected and leak-free. Check that the rigid conical head 10 is securely connected to the telescopic hose 9, and ensure that its bevel is aligned with the connection between the anti-clogging pipe 3 and the inlet 2. Confirm that the pressure relief valve 13, instrument 14 (pressure gauge), and other components are functioning properly.

[0038] Start the air pump 8 to extend and retract the telescopic hose 9. The telescopic hose 9 drives the rigid conical head 10 towards the port of the anti-clogging pipe 3. The material is then fed into the rubber chute 1 through the feed inlet 2. Under the influence of gravity, the material flows downward along the rubber chute 1 and enters the anti-clogging pipe 3.

[0039] Driven by the telescopic hose 9, the rigid conical head 10 is angled to align with the connection between the anti-clogging pipe 3 and the material inlet 2, creating a high-pressure airflow. This high-pressure airflow forms inside the anti-clogging pipe 3, effectively preventing material blockage. The pressure inside the anti-clogging pipe 3 is monitored in real time by the instrument 14 (pressure gauge) to ensure it remains within the normal range.

[0040] If the pressure is abnormal, adjust the operating status of air pump 8 promptly or check if the pressure relief valve 13 is working properly. Regularly check all connecting parts for looseness or damage to ensure normal equipment operation. Clean the accumulated material in the rubber chute 1 and anti-clogging pipe 3 to prevent blockage. Inspect and replace worn sealing rings to ensure sealing effectiveness. Stop air pump 8 to stop the telescopic hose 9 from extending or retracting. Clean and shut down the equipment, preparing for the next use.
