Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically a chute for clearing blockages and aiding flow. Background Technology

[0002] As a type of equipment that relies on the material's own gravity for inclined conveying, chutes have significant advantages such as simple structure, economic practicality, and high efficiency, and are therefore widely used in material transfer processes in various industrial fields such as mining, metallurgy, chemical industry, building materials, grain, and power. Their basic structure typically consists of an inclined trough, an inlet, an outlet, and necessary supporting frames. However, in actual operation, the physical properties of the material, especially its particle size distribution and moisture content, pose significant challenges to the smooth conveying of materials via chutes.

[0003] When materials have excessive moisture content or contain viscous components, they are prone to sticking and accumulating on the inner wall of the chute. This continuous material adhesion not only gradually reduces the effective flow cross-section of the chute but also eventually leads to chute blockage. Chute blockage not only severely reduces material transfer efficiency but also interrupts the production process, posing a serious threat to the safe, stable, and continuous operation of the entire production line. It is one of the key bottlenecks restricting the improvement of production efficiency. Utility Model Content

[0004] The present invention aims to provide a chute for clearing blockages and promoting flow, so as to avoid the problem of low production efficiency caused by material blockage in the chute.

[0005] To solve the above technical problems, the specific solution adopted by this utility model is as follows: it includes a tank body, an inlet located at the top of the tank body, and an outlet located at the bottom of the tank body. The tank body includes a bottom plate, a top plate, and two side plates connected between the bottom plate and the top plate. The bottom plate of the tank body is a stepped structure that slopes downward along the material flow direction. The bottom plate includes alternating inclined stepped surfaces and vertical surfaces. The outlines of the two side plates of the tank body are adapted to the outlines of the inclined stepped bottom plate. Each vertical surface of the inclined stepped bottom plate is provided with a nozzle array. The jet direction of each nozzle in the nozzle array is consistent with the inclined direction of the bottom plate. The nozzle array is connected to a jet pipe located on one side of the tank body through a branch pipe. The jet pipe is connected to the air supply port of the air compressor.

[0006] Further optimization of the chute for clearing blockages and aiding flow: Side flow nozzles are provided on both sides of each inclined step surface of the bottom plate. The jet direction of the side flow nozzles is towards the material flow direction and forms an inclination angle of 10°-30° with the bottom plate plane. The side flow nozzles are connected to the jet pipe through branch pipes.

[0007] Further optimization of the chute as a blockage clearing and flow aid: the side flow nozzles are distributed in a staggered array on the side plate.

[0008] Further optimization of the chute as a blockage clearing and flow aid: a vibrating motor is installed on the bottom plate directly below the chute inlet.

[0009] Further optimization of a chute for clearing blockages and aiding flow: the chute body is made by splicing together multiple sub-chute sections, and the end faces of adjacent sub-chute sections are fixedly connected by bolts.

[0010] Further optimization of the chute as a blockage clearing and flow aid: rubber strips for sealing and vibration damping are provided at the connection between adjacent sub-chasses, and bolts are used to tighten the rubber strips to form a sealing interface.

[0011] Further optimization of the chute as a blockage clearing and flow aid: an observation port is provided at the top plate of each section of the chute, and the observation port is covered by a sealing baffle hinged to the top plate.

[0012] Further optimization of the chute as a blockage clearing and flow aid: the contact part between the sealing baffle and the top plate is provided with a vibration damping layer.

[0013] Beneficial effects: The material is fed into the chute inlet of this utility model. The material slides on the inclined stepped bottom plate by its own weight. When the material passes through two adjacent steps, it is broken up by the impact force caused by the inclined step surface, which prevents the material from clumping and causing blockage. At the same time, the gas sprayed by the nozzle array on the vertical surface of the bottom plate can assist the material in sliding in the chute. Moreover, the design of the inclined stepped bottom plate also avoids the problem of material compaction at the bottom due to long-distance sliding, realizing a highly efficient continuous conveying process and improving production efficiency.

[0014] This invention utilizes side-flow nozzles on both side plates to ensure airflow covers the entire inclined step surface, preventing material blockage at the middle or end of each inclined step section on the bottom plate. The vibrating motor design allows material to be discharged from the chute under vibration, enhancing the chute's unblocking and flow-aiding effects and further improving production efficiency.

[0021] like Figure 1 As shown, a chute for clearing blockages and assisting flow includes a trough body 12, an inlet 2 located at the top of the trough body 12, and an outlet 9 located at the bottom of the trough body 12. The material enters the trough body 12 from the inlet 2 and slides out from the outlet 9 under the action of its own gravity, thus completing the material transfer.

[0022] The tank 12 includes a bottom plate 3, a top plate 13, and two side plates 1 connected between the bottom plate 3 and the top plate 13. The bottom plate 3, the top plate 13, and the two side plates 1 together form the tank 12. The bottom plate 3 is in direct contact with the material, providing a path for the material to slide down. The top plate 13, the two side plates 1, and the bottom plate 3 form a closed channel to prevent material from splashing and dust from overflowing.

[0023] like Figure 2 As shown, the bottom plate 3 of the tank 12 is a stepped structure that slopes downwards along the material flow direction. The bottom plate 3 includes alternating inclined stepped surfaces 16 and vertical surfaces 15. The design of the inclined stepped bottom plate 3 avoids the problem of material compaction at the bottom due to long-distance material sliding. When the material falls from one inclined stepped surface 16 to the adjacent inclined stepped surface 16, under the action of its own gravity, the material will be subjected to the impact force of the inclined stepped surface 16. The clumps of material will be broken up under the action of the impact force, thus preventing the material from clumping.

[0024] The contours of the two side plates 1 of the tank 12 are adapted to the inclined stepped bottom plate 3. The adapted bottom plate 3 and side plates 1 provide better sealing and save manufacturing materials.

[0025] like Figure 4 As shown, each vertical surface 15 of the inclined stepped base plate 3 is equipped with a nozzle array 7. The jet direction of each nozzle in the nozzle array 7 is consistent with the inclination direction of the base plate 3. The nozzle array 7 is connected to the jet pipe 6 located on one side of the tank 12 through a branch pipe 5. The jet pipe 6 is connected to the air supply port of the air compressor 8. The gas ejected by the nozzle array 7 forms a gas film on the inclined stepped surface 16, reducing the friction between the material and the bottom surface and effectively preventing the material from sticking to the base plate 3. At the same time, the airflow ejected by the nozzle array 7 provides the material with thrust along the inclination direction of the base plate 3, promoting the conveying of the material in the tank 12 and further preventing the material from clogging in the tank 12.

[0026] A vibratory motor 4 is installed on the bottom plate 3 directly below the feed inlet 2 of the trough 12. The vibration of the vibratory motor 4 loosens the material particles, reduces the material density, and makes it easier for the airflow from the nozzle array 7 and the side flow nozzle 14 to penetrate the material, thus improving the unblocking efficiency. The vibratory motor 4 is installed on the bottom plate 3 of the feed inlet 2 of the trough 12 because the first inclined step surface 16 of the bottom plate 3 does not have a corresponding nozzle array 7 to assist the material in sliding down. At the same time, the vibration intensity is greater closer to the vibratory motor 4. Therefore, installing the vibratory motor 4 on the bottom plate 3 of the feed inlet 2 of the trough 12 breaks the initial accumulation tendency of the material at the feed inlet 2, ensures that the material is evenly dispersed into the stepped section, and avoids the material clogging at the beginning of the chute.

[0027] like Figure 3 and Figure 5 As shown, the trough 12 is constructed by splicing together multiple sub-trough sections 11, with the end faces of adjacent sub-trough sections 11 fixed together by bolts. This modular construction method of the trough 12 facilitates on-site construction and subsequent maintenance. A sealing and vibration-damping rubber strip 18 is provided at the connection point of adjacent sub-trough sections 11. The bolts tighten the rubber strip 18 to form a sealed interface. The design of the rubber strip 18 increases the sealing performance between adjacent sub-trough sections 11, preventing material dust from spilling out. Simultaneously, the rubber strip 18 prevents adjacent sub-trough sections 11 from vibrating and colliding under the action of the vibrating motor 4, extending the service life of the chute.

[0028] Each section of the trough 11 has an observation port 17 at its top plate 13. The observation port 17 is covered by a sealing baffle 10 hinged to the top plate 13. A vibration-damping buffer layer 19 is provided at the contact point between the sealing baffle 10 and the top plate 13. The observation port 17 allows observation of the material conveying process within each section of the trough 11, enabling timely detection of material accumulation. If blockage occurs, workers can quickly clear the blockage at the observation port 17, avoiding frequent disassembly of the trough 12 and improving maintenance efficiency. The sealing baffle 10, hinged to the top plate 13, can open and close quickly, covering the observation port 17 when closed to ensure the trough 12's airtightness and prevent dust leakage. The vibration-damping buffer layer 19 isolates the impact transmitted by the vibration motor 4, preventing the sealing baffle 10 from failing or cracking.

[0029] Side-flow nozzles 14 are provided on each side plate 1 corresponding to each inclined step surface 16 of the base plate 3. The jet direction of the side-flow nozzles 14 is towards the material flow direction and forms an inclination angle of 10°-30° with the plane of the base plate 3. The side-flow nozzles 14 are connected to the jet pipe 6 through the branch pipe 5. The side-flow nozzles 14 are distributed in a staggered array on the side plate 1. The staggered array of side-flow nozzles 14 makes the airflow cover the entire chute, especially for the material on the side plates 1 of the chute, to prevent the material from sticking to the side plates 1. The inclination angle design makes the airflow ejected by the side-flow nozzles 14 split into vertical split and split along the plane of the base plate 3. The vertical airflow breaks the adhesion between the material and the base plate 3, while the split along the plane of the base plate 3, together with the nozzle array 7 located on the vertical surface 15, promotes the material to be transported in the tank 12.

[0030] The following is a method for using a chute for clearing blockages and promoting flow: First, start the air compressor 8 to supply air. After the air pressure stabilizes, turn on the vibration motor 4 and introduce the material from the inlet 2 of the chute body 12. Under the action of the vibration motor 3, the material can be evenly dispersed into the stepped chute body 12. After the material enters the stepped chute body 12, the nozzle array 7 located on the vertical surface 15 of the bottom plate 3 sprays air along the inclined step surface 16 to promote the material transport in the chute. At the same time, the side flow nozzles 14 distributed alternately on the side plate 1 further prevent material blockage. During operation, the material flow status is monitored through the observation port 17. After the material is transported, turn off the vibration motor 4 and wait for the material in the chute to be emptied before cutting off the air supply. Regularly open the observation port 17 to check and clean any residual material.
