Description

Technical Field

[0001] This invention relates to the field of storage equipment technology, specifically to a rotary unblocking component and control method for preventing blockages in silos. Background Technology

[0002] Currently, in the industrial production system, coal serves as a core energy resource supporting industrial operations. Its mining and storage play a crucial role in the stable and orderly operation of the industrial chain. Particularly in the coal storage stage, specialized silos are required for storage operations. When coal is discharged through the outlet at the bottom of the silo, blockages often occur due to excessively large coal particles or clumping. In such cases, unblocking devices must be used to clear the blockages at the outlet to ensure the normal discharge of coal.

[0003] Most existing unblocking components use a spiral agitator to agitate the discharge port, thereby disturbing the coal blocking the discharge port, causing the coal to break or crack, and allowing the coal to be discharged smoothly. However, in actual use, some coal contains moisture, which makes it sticky. This sticky material easily adheres to the inner wall of the discharge port, forming a material bridge, which aggravates the blockage and adversely affects the normal discharge of the material. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary unblocking component and control method for preventing blockages in silos, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a rotary unblocking component for preventing blockages in a hopper, comprising a hopper, a discharge frame mounted on the hopper, a rotating frame rotatably mounted on the discharge frame, a rotary motor mounted on the discharge frame to drive the rotating frame to rotate, and a spiral agitator mounted on the rotating frame for agitating and discharging the material; the spiral agitator consists of an outer spiral sleeve and an inner insert rod, the outer spiral sleeve being rotatably connected to the discharge hopper via a connecting frame one, and the inner insert rod being slidably mounted on the outer spiral sleeve and slidably connected to the rotating frame via a connecting frame two.

[0006] Furthermore, a track ring is installed on the hopper, and a sliding track is provided on the inner wall of the track ring. The bottom end of the inner rod extends into the track ring, and track balls are nested on the inner rod. The track balls are in rolling connection with the sliding track. The sliding track is inclined and arranged in a ring.

[0007] Furthermore, the outer spiral sleeve is composed of a sleeve and spiral blades. A receiving groove is opened on the spiral blades, and a collision block is slidably installed in the receiving groove. A collision spring is installed in the receiving groove, and one end of the collision spring is connected to the collision block. During the rotation of the spiral blades, as the rotation speed increases, centrifugal force is generated, causing the collision block to extend out of the receiving groove and collide with and break up the material.

[0008] Furthermore, the collision block adopts a three-claw design, that is, the collision block consists of a main block and two side blocks. Both side blocks are rotatably connected to the main block. Two fixed cylinders are installed in the storage groove. The two fixed cylinders are respectively positioned between the main block and the two side blocks. After the collision block extends out of the storage groove, the two side blocks are outwardly flared, which can create a tearing effect on the material.

[0009] Furthermore, a spiral blade is slidably installed on the sleeve, and the spiral blade is connected to the inner insert rod. A cone head is provided on the spiral blade. The spiral blade moves up and down with the inner insert rod, thereby causing the cone head to squeeze the material on the spiral blade, which facilitates the crushing of the material.

[0010] Furthermore, a spiral groove is provided on the inner insert rod, and a spiral plate is installed on the inner wall of the sleeve. The spiral plate extends into the spiral groove and is adapted to the spiral groove. A spiral airbag is provided in the spiral groove, and an air jet hole is provided on the sleeve. The air jet hole is connected to the spiral airbag. The spiral airbag is expanded and contracted as the inner insert rod rises and falls, thereby causing the gas in the spiral airbag to be ejected through the air jet hole to clean the surface of the spiral blade.

[0011] Furthermore, a collision frame is installed on the hopper. The collision frame is located above the inner rod. When the inner rod rises to the top, it can contact the collision frame and generate a collision. The collision force is transmitted to the hopper, causing vibration.

[0012] Furthermore, a one-way valve is installed inside the jet nozzle, an air intake pipe is installed on the spiral airbag, a one-way valve is installed on the air intake pipe, and the jet nozzle is set at an angle.

[0013] This invention relates to a method for controlling a rotary unblocking component for preventing blockage in a silo, comprising the following steps: S1: Install the hopper and spiral mixer onto the silo; S2: During the feeding process, the stirring motor is started to drive the rotating frame to rotate, which in turn drives the inner rod to rotate, and then drives the spiral outer sleeve to rotate, which stirs the material in the hopper and disperses the material. S3: During the rotation of the inner insert rod, under the action of the track ring and track balls, the inner insert rod moves up and down and reciprocates, colliding with the collision frame to generate vibration force, which drives the hopper to vibrate, causing the material on the inner wall of the hopper to fall off. S4: When the inner rod moves up and down, it drives the spiral blades to move up and down, and then the material is crushed by the combined action of the spiral blades. S5: During the rotation of the spiral blades, under the action of centrifugal force, one side of the collision block extends out of the receiving groove and collides with the material, breaking the material apart. Under the action of the fixed round block, the two side blocks on the collision block unfold, thereby tearing the material and breaking it apart. S6: When the inner rod moves up and down, it will cause the spiral airbag to expand and contract. Under the action of the jet hole, the airflow impacts the surface of the spiral blade and removes the residual material on the surface of the spiral blade.

[0014] The present invention has the following beneficial effects: (1) The present invention uses a spiral agitator to agitate the bottom of the hopper, thereby agitating the material and discharging it through the hopper. The spiral agitator consists of two parts: an inner rod and a spiral outer sleeve. This makes it convenient to replace the spiral agitator when it is worn, reducing economic losses. At the same time, the inner rod can be raised and lowered during rotation through the track ring and track ball bearings, thereby forming a reciprocating insertion and withdrawal motion trajectory. This can be coordinated with the vibration frame to vibrate the entire hopper, causing the material adhering to the inner wall of the hopper to fall off. Similarly, the shock waves generated by the vibration will also disperse the material, allowing it to be discharged from the hopper more effectively.

[0015] (2) By setting collision blocks on the spiral blades, the collision blocks extend out of the receiving groove under the action of centrifugal force during the rotation of the spiral agitator. Under the action of the collision spring, the collision blocks move back and forth in the receiving groove with the rotation speed of the spiral agitator, which facilitates the collision and dispersal of materials. When the collision blocks extend out of the receiving groove, the two side blocks on the collision blocks move in an unfolded state under the action of the two fixed cylinders, thereby forming a tearing shape, which better disperses the materials and ensures the normal feeding of materials.

[0016] (3) The present invention sets a spiral blade and a cone on the spiral blade. The spiral blade moves up and down with the inner rod. During the lifting and lowering of the spiral blade, the cone can squeeze and crush the material on the spiral blade, thereby reducing the blockage caused by excessive volume and further ensuring the normal feeding of materials.

[0017] (4) The present invention provides a spiral groove on the inner insert rod, a spiral air bag in the spiral groove, and a spiral plate on the inner wall of the sleeve, so that the inner insert rod reciprocates and expands the spiral air bag during the lifting and moving process. With the cooperation of the jet hole, a jet airflow is formed. The airflow can clean the surface of the spiral blade, reduce the adhesion of materials, and ensure the normal feeding of materials.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Please see Figures 1-8As shown, this invention is a rotary unblocking assembly for preventing blockages in a hopper, including a hopper 1, a feeding frame mounted on the hopper 1, a rotating frame 4 rotatably mounted on the feeding frame, and a rotary motor 2 mounted on the feeding frame to drive the rotating frame 4 to rotate. In actual use, a sealing mechanism is required at the bottom of the feeding frame to block the feeding. This can be achieved by fixing a sealing plate to the bottom of the feeding frame with bolts. The rotary motor 2 and the rotating frame 4 are connected by gear meshing. In actual use, a reducer can be used as an intermediate connecting component to connect the rotary motor 2 and the rotating frame 4. A spiral agitator 3 is mounted on the rotating frame 4 to agitate the material. The material is stirred and fed; the spiral mixer 3 consists of an outer spiral sleeve and an inner rod 301. The outer spiral sleeve is rotatably connected to the feeding hopper 1 through a connecting frame 1. The inner rod 301 is slidably installed on the outer spiral sleeve and is slidably connected to the rotating frame 4 through a connecting frame 2. The connecting frame 1 consists of a sliding ring 1 and three connecting plates 1. All three connecting plates 1 are installed on the sliding ring 1, and the other side of each of the three connecting plates 1 is connected to the rotating frame 4. A groove 1 is provided on the inner rod 301, and a slider is installed on the sliding ring 1. The slider is slidably connected to the groove 1. One side of each of the three connecting plates 1 is blade-shaped to facilitate cutting and dispersing the material during rotation with the rotating frame 4.

[0023] A track ring 6 is installed on the hopper 1. A sliding track is provided on the inner wall of the track ring 6. The bottom end of the inner rod 301 extends into the track ring 6. A track ball 7 is nested on the inner rod 301. The track ball 7 is in a rolling connection with the sliding track. The sliding track is inclined and circular. Through the setting of the sliding track, the inner rod 301 can reciprocate and move up and down during rotation.

[0024] The outer spiral sleeve consists of a sleeve 302 and spiral blades 303. The sleeve 302 is connected to the hopper 1 via a rotating frame, and the sleeve 302 and the rotating frame are rotatably connected. The spiral blades 303 are mounted on the sleeve 302 and have a receiving groove. A collision block 10 is slidably installed in the receiving groove, and a collision spring 9 is installed in the receiving groove. One end of the collision spring 9 is connected to the collision block 10. During the rotation of the spiral blades 303, as the rotation speed increases, centrifugal force is generated, causing the collision block 10 to extend out of the receiving groove and collide with and break up the material. After the rotation speed of the outer spiral sleeve decreases, the collision spring 9 will pull the collision block 10 to retract into the receiving groove, so that the collision block 10 can reciprocate in and out of the receiving groove, thereby colliding with and breaking up the material in the outer spiral sleeve.

[0025] The collision block 10 adopts a three-claw design, that is, the collision block 10 consists of a main block and two side blocks. Both side blocks are rotatably connected to the main block. Two fixed cylinders are installed in the storage groove. The two fixed cylinders are respectively set between the main block and the two side blocks. After the collision block 10 extends out of the storage groove, the two side blocks are outwardly flared, which can create a tearing effect on the material.

[0026] A spiral blade 8 is slidably mounted on the sleeve 302. The spiral blade 8 is connected to the inner insert rod 301. A second groove is provided on the sleeve 302. A second slider is installed on the spiral blade 8. The second slider is slidably connected to the second groove. A cone head is provided on the spiral blade 8. The spiral blade 8 moves up and down with the inner insert rod 301, thereby causing the cone head to squeeze the material on the spiral blade 303, which facilitates the crushing of the material. At the same time, the up and down movement of the spiral blade 8 can also form a digging action on the material, so that the material can fall better and faster.

[0027] The inner insert rod 301 has a spiral groove, and a spiral plate 12 is installed on the inner wall of the sleeve 302. The spiral plate 12 extends into the spiral groove and is adapted to the spiral groove. A spiral airbag 11 is installed in the spiral groove. An air jet hole is opened on the sleeve 302 and is connected to the spiral airbag 11. The spiral airbag 11 expands and contracts with the raising and lowering of the inner insert rod 301, thereby causing the gas in the spiral airbag 11 to be ejected through the air jet hole to clean the surface of the spiral blade 303. A one-way valve is installed in the air jet hole. An air inlet pipe is installed on the spiral airbag 11, and a one-way valve is installed on the air inlet pipe. The air jet hole is inclined. In actual use, a filter screen is installed on the outer end of the air jet hole and the air inlet end of the air inlet pipe to prevent materials from entering the spiral airbag 11.

[0028] A collision frame 5 is installed on the hopper 1. The collision frame 5 is located above the inner insertion rod 301. When the inner insertion rod 301 rises to the top, it can contact the collision frame 5 and generate a collision. The collision force is transmitted to the hopper 1, which generates vibration. The vibration force is transmitted to the hopper 1, causing the material adhering to the inner wall of the hopper 1 to fall off. At the same time, it can also disperse the material passing through the collision frame 5.

[0029] In use, the hopper 1 and the spiral agitator 3 are installed on the hopper. During the feeding process, the agitator motor is started to drive the rotating frame 4 to rotate, which in turn drives the inner rod 301 to rotate, and then drives the spiral outer sleeve to rotate, thus agitating and dispersing the material in the hopper, allowing the material to slide out of the hopper 1. During this process, under the action of the track ring 6 and track balls 7, the inner rod 301 on the spiral agitator 3 moves up and down in a circular motion. When the inner rod 301 rises to its highest position, it collides with the collision frame 5 on the hopper 1, causing the hopper 1 to vibrate. This vibration causes the material in the hopper 1 to vibrate and become loose, allowing the material to fall stably. At the same time, during the rotation of the spiral blades 303, the centrifugal force... The collision block 10 extends into a receiving groove on one side and collides with the material, breaking it apart. Under the action of the fixed round block, the two side blocks on the collision block 10 unfold, tearing the material and breaking it apart. At the same time, the lifting and lowering movement of the inner rod 301 drives the spiral airbag 11 to retract and expand, causing the gas in the spiral airbag 11 to be discharged from the jet hole, which then impacts the surface of the spiral blade 303 with airflow, removing residual material from the surface of the spiral blade 303. Simultaneously, when the inner rod 301 lifts and lowers, it also drives the spiral blade 8 to move up and down, and then, under the combined action of the spiral blade 303, the material is crushed by compression. In summary, the material can be stably discharged from the hopper 1, reducing material blockage.

[0030] This invention relates to a method for controlling a rotary unblocking component for preventing blockage in a silo, comprising the following steps: S1: Install the hopper 1 and the spiral mixer 3 onto the silo; S2: During the feeding process, the stirring motor is started to drive the rotating frame 4 to rotate, which in turn drives the inner rod 301 to rotate, and then drives the spiral outer sleeve to rotate, which stirs the material in the hopper and disperses the material. S3: During the rotation of the inner insertion rod 301, under the action of the track ring 6 and the track ball 7, the inner insertion rod 301 moves up and down and reciprocates, and collides with the collision frame 5 to generate vibration force, which drives the feeding hopper 1 to vibrate, causing the material on the inner wall of the feeding hopper 1 to fall off. S4: When the inner rod 301 moves up and down, it drives the spiral blade 8 to move up and down, and then the material is crushed by the combined action of the spiral blade 303. S5: During the rotation of the spiral blade 303, under the action of centrifugal force, one side of the collision block 10 extends out of the receiving groove and collides with the material, breaking the material apart. Under the action of the fixed round block, the two side blocks on the collision block 10 unfold, thereby tearing the material and breaking it apart. S6: When the inner rod 301 moves up and down, it will drive the spiral airbag 11 to retract and expand. Under the action of the jet hole, the airflow impacts the surface of the spiral blade 303, removing the residual material on the surface of the spiral blade 303.
