A steel silo to prevent material accumulation

Abstract

This utility model relates to the field of steel silos, specifically to a steel silo designed to prevent material accumulation. It includes a silo body and at least two arc-shaped guide channels equidistantly spaced along the circumference of the inner wall of the silo. Guide blocks are slidably installed inside the arc-shaped guide channels, and a cleaning component is fixed to one end of each guide block. The cleaning component includes a crossbar and a brush plate at the end of the crossbar, with cleaning bristles on the side of the brush plate facing the inner wall of the silo. This utility model, through the arrangement of the arc-shaped guide channels, cleaning component, and counterweight, allows the counterweight to fall and rotate the cleaning component to scrape the wall when the material decreases. This achieves adaptive cleaning based on material height changes, low power consumption, and full coverage. Furthermore, the inclined surface at the bottom of the arc-shaped guide channels and the inclined surface at the bottom of the guide blocks directly correspond to the adaptive scraping of the counterweight, avoiding guide channel jamming.

Description

Technical Field

[0001] This utility model relates to the field of steel silos, and more particularly to a steel silo that prevents material accumulation. Background Technology

[0002] Steel silos are widely used in the storage of various bulk materials such as grain, cement, fly ash, mineral powder, chemical raw materials, and feed due to their advantages of high structural strength, short construction period, good sealing, and large capacity. However, in actual operation, especially when storing materials with hygroscopic, adhesive, or easily caking properties (such as certain high-moisture grains, damp cement, sticky mineral powder, and specific chemical powders), a common and persistent technical problem seriously restricts their efficiency and safety—namely, the problem of material adhesion and accumulation on the silo walls. To address material accumulation and blockages, silo wall vibrators or pneumatic unblocking devices (such as air cannons) are commonly used. However, these devices have significant drawbacks: high energy consumption, frequent starts of the vibrator or air cannon consume large amounts of electrical energy or compressed air, resulting in high operating costs, and the intense vibrations may cause fatigue damage to the silo structure (especially welds), posing safety hazards with long-term use; When mechanical unblocking fails, manual cleaning is often necessary, which is not only labor-intensive, inefficient, and costly, but also poses a high safety risk. Utility Model Content

[0003] In view of this, the purpose of this utility model is to propose a steel silo that prevents material accumulation, so as to solve the technical problems in the prior art.

[0004] Based on the above objectives, this utility model provides a steel silo for preventing material accumulation, including a silo body and at least two arc-shaped guide grooves equidistantly opened along the circumference on the inner wall of the silo body, wherein guide blocks are slidably installed inside the arc-shaped guide grooves; A cleaning component fixed to one end of the guide block, the cleaning component including a crossbar and a brush plate disposed at the end of the crossbar, and the brush plate having cleaning bristles on the side facing the inner wall of the chamber. The other end of the crossbar is fixedly connected to a connecting ring, and a counterweight is rotatably installed on the inner ring of the connecting ring. The counterweight is configured to drive the cleaning component to rotate downward along the arc-shaped guide groove when the powder in the hopper decreases. A traction rope is fixed to the top of the counterweight, and the traction rope passes through a perforation at the top of the chamber. A support frame is located on the top of the silo body, and a winding roller is rotatably mounted on the support frame. The free end of the traction rope is wound around the winding roller.

[0005] Preferably, the bottom of the arc-shaped guide groove is set as an inclined surface.

[0006] Preferably, the bottom of the guide block is an inclined surface, and the inclined surface gradually moves away from the cleaning component from top to bottom.

[0007] Preferably, the guide block has grooves on both sides, and ball bearings that overlap the inner wall of the arc-shaped guide groove are rotatably installed in the grooves.

[0008] Preferably, the brush plate has an arc-shaped structure, and multiple brush plates are arranged to form a ring that matches the curvature of the inner wall of the chamber.

[0009] Preferably, the steel silo further includes an AC induction motor fixed to the support frame, the output end of which is connected to a take-up roller.

[0010] Preferably, bearings are provided on the surfaces at both ends of the take-up roller, and the inner ring of the bearing is fixedly connected to the surface of the take-up roller, and the outer ring of the bearing is fixedly connected to the interior of the support frame.

[0013] Preferably, a sealing ring is provided between the traction rope and the perforation at the top of the container.

[0014] The beneficial effects of this utility model are as follows: The steel silo with anti-material accumulation of this utility model, through the setting of components such as arc-shaped guide groove, cleaning component and counterweight, so that when the material decreases, the falling of the counterweight drives the rotating cleaning component to scrape the wall, realizing adaptive material height change, low power consumption and full coverage cleaning effect. In addition, the design of the bottom slope of the arc-shaped guide groove and the bottom inclined surface of the guide block directly corresponds to the adaptive scraping of the counterweight, avoiding the problem of guide groove jamming. By using components such as a traction rope, an AC induction motor, and cleaning parts, after the powder in the silo is emptied, the traction rope drives the cleaning parts to rotate upward along the arc-shaped guide groove to perform rotary scraping of the wall. After rising to the correct position, under the action of the counterweight, the cleaning parts on the connecting ring are driven to rotate downward again along the arc-shaped guide groove. This process is repeated to achieve rotary cleaning of the inner wall of the steel silo, increase the cleaning range of the cleaning parts, improve the cleaning effect, and avoid blind spots in the operation.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] The first aspect of this utility model proposes a steel silo to prevent material accumulation, such as... Figure 1-6 As shown, it includes a container body 1 and at least two arc-shaped guide grooves 2 that are equidistantly opened along the circumference on the inner wall of the container body 1, and guide blocks 3 are slidably installed inside the arc-shaped guide grooves 2; A cleaning component 4 is fixed to one end of the guide block 3. The cleaning component 4 includes a crossbar and a brush plate provided at the end of the crossbar, and the brush plate is provided with cleaning bristles on the side facing the inner wall of the chamber 1. A connecting ring 5 is fixedly connected to the other end of the crossbar. A counterweight 6 is rotatably installed on the inner ring of the connecting ring 5. The counterweight 6 is configured to drive the cleaning component 4 to rotate downward along the arc-shaped guide groove 2 when the powder in the silo body 1 decreases. When the material in the steel silo decreases, the counterweight 6 falls under its own weight. At the same time, since the connecting ring 5 is rotatably installed on the counterweight 6, the cleaning component 4 fixed on the outer wall of the connecting ring 5 can rotate downward along the arc-shaped guide groove 2 during material feeding, and perform rotating scraping of the material inside the steel silo.

[0021] The traction rope 7 is fixed to the top of the counterweight 6 and passes through the perforation at the top of the chamber 1. A support frame 9 is located on the top of the bin body 1, and a winding roller 8 is rotatably mounted on the support frame 9. The free end of the traction rope 7 is wound around the winding roller 8.

[0022] In this embodiment, the bottom of the arc-shaped guide channel 2 is set as an inclined surface. This allows the powder at the bottom of the arc-shaped guide channel 2 to be moved out of the inside of the arc-shaped guide channel 2 through the inclined surface, avoiding the accumulation of material on the inner wall of the arc-shaped guide channel 2.

[0023] In this embodiment, the bottom of the guide block 3 is an inclined surface, and this inclined surface gradually moves away from the cleaning component 4 from top to bottom. As the guide block 3 descends along the inner wall of the corresponding arc-shaped guide groove 2, the bottom of the guide block 3, through the inclined surface, can scrape off the powder adhering to the inner wall of the arc-shaped guide groove 2, preventing the powder from adhering to the inner wall of the arc-shaped guide groove 2 and affecting the movement of the guide block 3.

[0024] In this embodiment, grooves are provided on both sides of the guide block 3, and ball bearings 301 are rotatably installed in the grooves, overlapping the inner wall of the arc-shaped guide groove 2. By setting the ball bearings 301, the contact area between the two sides of the guide block 3 and the inner wall of the arc-shaped guide groove 2 is reduced, the friction between the two is reduced, and the stability of the movement of the guide block 3 is improved.

[0025] In this embodiment, the brush plate has an arc-shaped structure, and multiple brush plates are arranged to form a ring that matches the curvature of the inner wall of the silo body 1. The number of brush plates can be set to 2-4, and after being enclosed, they can thoroughly clean the inner wall of the steel silo.

[0026] In this embodiment, the steel silo also includes an AC induction motor 10 fixed to the support frame 9, with the output end of the AC induction motor 10 connected to the take-up roller 8. It should be noted that when the AC induction motor 10 is de-energized, the stator windings have no current and do not generate a magnetic field. The rotor is typically a squirrel-cage structure or a wound-rotor type, lacking permanent magnets. Therefore, there is no electromagnetic attraction or repulsion between the rotor and stator. Consequently, the shaft can rotate relatively freely, allowing the counterweight 6 to fall and drive the cleaning component 4 to rotate and scrape the wall as the material decreases. This achieves adaptive material height changes, low power consumption, and full-coverage cleaning.

[0027] In this embodiment, bearings are provided on the surfaces of both ends of the take-up roller 8, with the inner ring of the bearing fixedly connected to the surface of the take-up roller 8 and the outer ring of the bearing fixedly connected to the interior of the support frame 9. The bearing configuration improves the rotational stability of the take-up roller 8.

[0028] In this embodiment, the steel silo also includes a switch button 11 fixed to the top wall of the silo body 1. The switch button 11 is electrically connected to the AC induction motor 10, and the pressing end of the switch button 11 is located at the top limit position of the rising path of the counterweight block 6.

[0029] After the powder inside the silo 1 is emptied, during the cleaning of the inner wall of the silo 1, the AC induction motor 10 is started. The output end of the AC induction motor 10 drives the traction rope 7 wound on the take-up roller 8 to wind up, causing the traction rope 7 to drive the counterweight 6 to rise. At this time, the cleaning component 4 rotates upward along the arc-shaped guide groove 2 to perform rotational scraping of the wall, thereby scraping off the powder adhering to the inner wall of the steel silo. When the AC induction motor 10 drives the traction rope 7 wound on the take-up roller 8 to rise to the position, the counterweight 6 moves upward and presses against the pressing end of the switch button 11, causing the AC induction motor 10 to stop driving the take-up roller 8 to rotate. At this time, under the action of the counterweight 6, the cleaning component 4 on the connecting ring 5 is driven to rotate downward along the guide of the arc-shaped guide groove 2, realizing the rotational cleaning of the inner wall of the steel silo, increasing the cleaning range of the cleaning component 4, improving the cleaning effect, and avoiding blind spots in the operation.

[0030] In this embodiment, the traction rope 7 is made of polyester fiber. The polyester fiber material provides it with good abrasion resistance and durability.

[0031] In this embodiment, a sealing ring is provided between the traction rope 7 and the perforation at the top of the hopper 1. This sealing ring prevents dust and moisture from entering the interior of the hopper 1, thus avoiding powder clumping.

[0032] Working principle: When storing powder in a steel silo, the material remains stationary for a long time. Under its own weight and the force between particles, it will adhere to the inner wall of the silo, resulting in material hanging. A large amount of material adheres to the silo wall and cannot be discharged, causing waste and potentially affecting the purity of subsequent batches of material. Therefore, during powder discharge, as the amount of powder in the silo gradually decreases, the counterweight 6 falls under its own weight. At the same time, since the connecting ring 5 is rotatably installed on the counterweight 6, the cleaning part 4 fixed on the outer wall of the connecting ring 5 can rotate downward along the arc-shaped guide groove 2 during material discharge, rotating and scraping the inside of the steel silo. After the powder inside the silo 1 is emptied, during the thorough cleaning of the inner wall of the silo 1, the AC induction motor 10 is started. The output end of the AC induction motor 10 drives the traction rope 7 wound on the take-up roller 8 to wind up, causing the traction rope 7 to drive the counterweight 6 to rise. At this time, the cleaning component 4 rotates upward along the arc-shaped guide groove 2 to perform rotational scraping, thereby scraping off the powder adhering to the inner wall of the steel silo. When the AC induction motor 10 drives the traction rope 7 wound on the take-up roller 8 to rise to the position, the counterweight 6 moves upward and presses against the pressing end of the switch button 11, causing the AC induction motor 10 to stop driving the take-up roller 8 to rotate. At this time, under the action of the counterweight 6, the cleaning component 4 on the connecting ring 5 is driven to rotate downward along the guide of the arc-shaped guide groove 2 again. This process is repeated to achieve rotational cleaning of the inner wall of the steel silo.
