Description

Technical Field

[0001] This utility model relates to the field of steel silo technology, specifically to a grain steel silo cleaning device. Background Technology

[0002] Steel silos are storage containers made of steel plates riveted, welded, or assembled. Steel silos have the advantages of fast construction and high efficiency. They can shorten the material loading and unloading process, reduce operating and maintenance costs, eliminate heavy bagging operations, and facilitate mechanized and automated operations. Therefore, they have become one of the most important forms of grain storage.

[0003] A known Chinese patent (application number: CN201922220728.6) discloses a steel silo for grain storage, comprising a silo body, an insulation layer, and a base. The silo body includes an inner wall, an outer wall, and a top cover. The insulation layer is disposed between the inner wall and the outer wall. The silo body is connected to a dehumidifier and a temperature regulator. A ventilation pipe is disposed at the center of the silo body, and a first vent is opened on the wall of the ventilation pipe. The dehumidifier is provided with an air inlet pipe and an air outlet pipe. The air inlet pipe is connected to the silo body, and the air outlet pipe is connected to the ventilation pipe. The temperature regulator is connected to the ventilation pipe. The dehumidifier and temperature regulator can keep the temperature and humidity inside the silo body within a reasonable range. A ventilation pipe and a spiral coil are disposed at the center of the steel silo body. A motor is disposed on the silo body, and the motor drives the ventilation pipe and the spiral coil to rotate, thereby accelerating the cooling and dehumidification of the center of the grain. The steel silo body is provided with removable partitions, making the internal space of the silo body more flexible in use and helping to reduce the storage cost of grain.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned steel silo for grain storage: the existing steel silos have steep walls, and the materials are prone to arching and sticking to the walls, which leads to poor material discharge, difficulty in cleaning, and reliance on high-risk manual labor. Therefore, a grain steel silo cleaning device was proposed. Utility Model Content

[0005] This utility model proposes a grain steel silo cleaning device, which solves the problems of existing steel silos in related technologies, such as steep silo walls, easy material arching and wall adhesion, resulting in poor material discharge, difficult cleaning, and reliance on high-risk manual labor.

[0006] The technical solution of this utility model is as follows: A grain steel silo cleaning device, comprising: Warehouse body; Two electric push rods are fixedly installed on the top of the compartment body. The output ends of the two electric push rods are fixedly connected to a strip plate. A motor is fixedly installed at the bottom of the strip plate. The output end of the motor is fixedly connected to a disc. Multiple connecting ropes are provided at the bottom of the disc, and rubber balls are provided at the bottom ends of the multiple connecting ropes. A stirring rod is fixedly installed at the center of the bottom of the disc. The dust removal mechanism is located at the top of the silo.

[0007] Preferably, the dust removal mechanism includes: An L-shaped tube is fixedly installed on the top of the chamber, and the L-shaped tube is located on one side of the two electric push rods; The filter screen, activated carbon filter screen, and high-efficiency air filter are arranged sequentially from bottom to top on the inner wall of the L-shaped tube.

[0008] Preferably, the dust removal mechanism further includes: The fan is fixedly installed at the center inside the L-shaped tube by a fixing plate; A dust cover is fixedly installed at one end of the L-shaped tube.

[0009] Preferably, a plurality of support legs are fixedly installed at the bottom of the outer side wall of the hopper, and the plurality of support legs are arranged in a circular array.

[0010] Preferably, the outer wall of the silo is coated with an anti-corrosion coating, specifically an epoxy zinc-rich primer.

[0011] Preferably, the anti-corrosion coating is coated with a weather-resistant coating on the outer wall away from the silo body, specifically a polyurethane topcoat.

[0012] The working principle and beneficial effects of this utility model are as follows: During the emptying process, if slow discharge occurs, the motor is started, driving the disc to rotate inside the silo. The centrifugal force of the rotation causes the rubber ball on the connecting rope to rotate inside the silo. Simultaneously, the rubber ball collides with the inner wall of the silo, causing high-frequency micro-vibration between the inner wall and the material layer. This vibration effectively reduces the internal friction between the materials and the external friction between the materials and the inner wall of the silo, enhancing the material's fluidity and changing it from a "static" to a "moving" state. This allows the material to flow smoothly. At the same time, the rotating stirring rod inside the silo uses mechanical force to directly break up any arching, dispersing the material and restoring its gravity flow. This achieves the goal of smooth material emptying and effectively prevents problems caused by material arching or sticking to the walls, which can lead to poor discharge.

Detailed Implementation

[0016] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0017] Please see Figure 1 - Figure 5 A grain steel silo cleaning device, comprising: Warehouse 1; Two electric push rods 2 are fixedly installed on the top of the compartment 1. The output ends of the two electric push rods 2 are fixedly connected to strip plates 3. A motor 4 is fixedly installed at the bottom of the strip plates 3. A disc 5 is fixedly connected to the output end of the motor 4. Multiple connecting ropes 6 are set at the bottom of the disc 5, and rubber balls 7 are set at the bottom ends of the multiple connecting ropes 6. A stirring rod 8 is fixedly installed at the center of the bottom of the disc 5.

[0018] The technical solution provided by this utility model is as follows: During the clearing process, if slow material discharge occurs, the motor 4 is started, which drives the disc 5 to rotate inside the silo 1. The centrifugal force of the rotation causes the rubber ball 7 on the connecting rope 6 to rotate inside the silo 1. At the same time, the rubber ball 7 collides with the inner wall of the silo 1, causing the inner wall of the silo 1 and the material layer to vibrate at high frequency and micro amplitude. This vibration effectively reduces the internal friction between materials and the external friction between materials and the inner wall of the silo 1, thereby enhancing the fluidity of the materials and changing them from a "static" state to a "moving" state. This allows the materials to flow smoothly. Simultaneously, the stirring rod 8 rotates inside the silo 1, using mechanical force to directly break up any arching and disperse the materials, restoring the gravity flow of the materials. This achieves the purpose of smooth material clearing and effectively prevents the problem of poor material discharge caused by material arching and wall adhesion.

[0019] Furthermore, multiple support legs 10 are fixedly installed at the bottom of the outer side wall of the compartment 1, and the multiple support legs 10 are arranged in a circular array.

[0020] Specifically, multiple support legs 10 are used to support and fix the container body 1, which effectively improves the stability of the container body 1.

[0021] Furthermore, the outer wall of the silo body 1 is coated with an anti-corrosion coating 11, specifically an epoxy zinc-rich primer, and the outer wall away from the anti-corrosion coating 11 is coated with a weather-resistant coating 12, specifically a polyurethane topcoat.

[0022] Specifically, the epoxy zinc-rich primer of the anti-corrosion coating 11 is used to isolate the external anti-corrosion medium and prevent the silo body 1 from rusting, thereby extending the service life of the silo body 1. The polyurethane topcoat of the weather-resistant coating 12 increases the UV resistance and wear resistance of the silo body 1. Example

[0023] Based on Embodiment 1, in this embodiment: the dust removal mechanism 9 is set on the top of the chamber 1. The dust removal mechanism 9 includes: an L-shaped tube 90, which is fixedly installed on the top of the chamber 1 and is located on one side of the two electric push rods 2; a filter screen 91, an activated carbon filter screen 92, and a high-efficiency air filter 93, which are arranged sequentially from bottom to top on the inner wall of the L-shaped tube 90; the dust removal mechanism 9 also includes: a fan 94, which is fixedly installed at the center inside the L-shaped tube 90 by a fixing plate; and a dust cover 95, which is fixedly installed at one end of the L-shaped tube 90.

[0024] The technical solution provided in this embodiment is as follows: When the material enters the silo 1, the fan 94 is activated to suck out the dust from the silo 1. The dust in the sucked gas is filtered and intercepted by the filter screen 91, the activated carbon filter screen 92 and the high-efficiency air filter 93. The filtered gas is then discharged through the L-shaped pipe 90, and the dust cover 95 prevents external dust from entering the L-shaped pipe 90. This achieves the purpose of dust removal when the material enters the silo 1, effectively preventing the direct emission of dust-containing gas into the environment and causing environmental pollution.

[0025] The working principle of this utility model is as follows: During the clearing process, if slow material discharge occurs, the motor 4 is started. The motor 4 drives the disc 5 to rotate inside the bin 1. The centrifugal force of the rotation causes the rubber ball 7 on the connecting rope 6 to rotate inside the bin 1. At the same time, the rubber ball 7 collides with the inner wall of the bin 1, causing the inner wall of the bin 1 and the material layer to vibrate at high frequency and micro amplitude. This vibration effectively reduces the internal friction between the materials and the external friction between the materials and the inner wall of the bin 1, thereby enhancing the fluidity of the materials and changing them from a "static" state to a "moving" state. This allows the materials to flow smoothly. Meanwhile, the stirring rod 8 rotates inside the bin 1, using mechanical force to directly break up any arching and disperse the materials, restoring the gravity flow of the materials. This achieves the purpose of smooth material clearing and effectively prevents the problem of poor material discharge caused by material arching and wall adhesion.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
