Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a dust removal device for grain storage. Background Technology

[0002] Grains mainly include rice, wheat, soybeans, and other miscellaneous grains. Grains are processed into staple foods, providing humans with energy, protein, and vitamin B1. The nutrient content of grains can vary greatly depending on the type, variety, origin, growing conditions, and processing methods.

[0003] Application number CN202323353824.0 discloses a grain dust removal device, including a housing with a working chamber inside. An inlet is located at the top of the housing, and an outlet is located at the bottom of the housing on the side away from the inlet. Both the inlet and outlet are connected to the working chamber. A dust removal mechanism is provided on one side of the outlet. A guide plate for guiding the grain is provided inside the working chamber. This utility model relates to the field of grain dust removal technology. This grain dust removal device, through the guide plate, can adsorb static electricity on the grain, thus preventing floating dust from adhering to the grain. Furthermore, when the grain enters through the inlet and comes into contact with the guide plate, an impact force is generated, which shakes the floating dust away from the grain, allowing a fan to easily remove the dust.

[0004] The equipment only removes floating dust through the dust removal mechanism (fan), but there is no dust collection or guiding structure in the working chamber. The floating dust that is shaken off diffuses irregularly in the working chamber. Some dust may adhere to the inner wall of the shell or be re-adsorbed on the surface of the grain due to the turbulent airflow, forming secondary pollution. Other dust may be discharged from the discharge port with the grain, resulting in incomplete dust removal and failure to achieve efficient and centralized dust removal. Utility Model Content

[0005] The purpose of this invention is to provide a dust removal device for grain storage, which solves the problem of dust not being directed in any direction, easily causing secondary pollution or residue.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a dust removal device for grain storage, comprising a fixed device and a blower assembly. The blower assembly is installed at the front end of the fixed device. The fixed device includes a body, with a sloping groove at the top and rear end of the body. A dust outlet is provided on the side of the body near the sloping groove. A flow divider is provided at the front end of the body, and a motor is provided at the front end of the flow divider. A blower fan is installed at the output end of the motor and corresponds to the dust outlet. Dust sieves are fixedly installed on the inner walls around the dust outlet. Three sets of sieve plates are fixedly connected in parallel on the inner wall of the body, with the sieve holes of the three sets of sieve plates arranged sequentially from top to bottom.

[0007] The purpose of this design is that, during the operation of the equipment, after the grains enter the machine, they first come into contact with the diversion bar at the front of the machine. The diversion bar disperses the clumps of grains into smaller streams through a grid structure, preventing them from accumulating and clogging the subsequent screening path. The dispersed grains fall onto three sets of screen plates that are fixed parallel to each other on the inner wall of the machine. The screen holes of the three sets of screen plates decrease in size from top to bottom: the upper screen plate intercepts large grain particles, the middle screen plate intercepts medium grain particles, and the lower screen plate receives small grain particles. At the same time, light impurities such as dust and debris mixed in the grains can penetrate downwards through the screen holes of each layer due to their small particle size, thus achieving the initial separation of grains and impurities. At this time, the motor at the front of the machine starts, driving the blower fan at the output end to rotate at high speed. The airflow generated by the blower fan enters the machine evenly through the gap of the grid of the diversion bar. Since the weight of dust is much lighter than that of grain, the airflow will blow these light impurities upward and make them gather in the inclined groove area at the top and rear of the machine. The inclined angle of the sloping trough can guide the accumulated dust to flow along the sloping surface to the nearby dust outlet. The dust screen plates on the inner wall around the dust outlet are funnel-shaped, and their mesh only allows dust to pass through. They can intercept small grain particles mixed in with the airflow. Finally, the pure dust is filtered by the dust screen plates and discharged from the dust outlet, completing the complete separation of dust and grain. The three sets of sieve plates are graded according to the size of the sieve holes, which can separate grains of different particle sizes and allow dust to fully penetrate, realizing the dual function of "grain grading + impurity separation". The inclined groove specifically guides light dust to gather and flow to the dust outlet, solving the problem of dust floating around in the machine and improving the efficiency of directional dust discharge. The dust sieve plate accurately intercepts fine grains at the dust outlet, preventing grains from being lost with dust during the dust removal process and reducing resource consumption.

[0008] Furthermore, a feed hopper is provided on the top side of the machine body away from the inclined groove.

[0009] The purpose of this design is to ensure that, during the operation of the equipment, after the grain slides down the inner wall of the feed hopper, it falls precisely into the area above the three sets of screen plates, ensuring that the material enters the screening stage in a concentrated manner. This provides a continuous and stable material flow for the subsequent grading and separation of the screen plates and the dust removal of the blower components, preventing the grain from scattering to other areas of the machine and causing waste or cleaning burden.

[0010] Furthermore, a vibrator is fixedly installed on the outer wall of one side of the bottom of the machine body, and the vibrator is adjacent to three sets of sieve plates.

[0011] The purpose of this design is that, during the operation of the equipment, after the vibrator on one side of the bottom of the machine is started, the high-frequency vibration generated is transmitted through the inner wall of the machine to the three adjacent sets of screen plates, causing the screen plates to vibrate slightly in the vertical direction. During the vibration, the grains on the screen plates are constantly turned over and loosened, making it easier for the dust wrapped in the grains to fall off and be exposed. At the same time, the vibration can break the adsorption force between the grain particles, prevent the screen holes from being blocked by grains, and allow dust and fine impurities to pass through the screen holes smoothly, creating conditions for the subsequent blower to blow the dust to the inclined groove area, thus enhancing the synergistic dust removal effect of the screen plates and the blower assembly.

[0012] Furthermore, the bottom surface of the machine body is provided with two sets of discharge hoppers, and the inner wall of the bottom surface of the machine body near the two sets of discharge hoppers is provided with diamond-shaped guide plates respectively.

[0013] The purpose of this design is that, during the operation of the equipment, the diamond-shaped guide plates on the inner wall of the bottom surface of the machine guide large grain particles falling from the upper screen plate to one side discharge hopper through symmetrical inclined edges, and guide medium and small grain particles falling from the middle and lower screen plates to the other side discharge hopper. The acute angle structure of the diamond-shaped guide plates can cut off the accumulation trend of grains when they fall, ensuring that grains of different sizes quickly enter the corresponding discharge hoppers along a fixed path, realizing the orderly discharge of grains after grading, and facilitating storage according to particle size.

[0014] Furthermore, the bottom surface of the machine body is provided with a buffer support at each of the four corners, and the front end of the buffer support is provided with a fixed bracket in parallel.

[0015] The purpose of this design is that during the operation of the equipment, the vibration of the vibrator and the rotation of the blower will cause the machine body to shake as a whole. The damping supports around the bottom of the machine body absorb the vibration energy through built-in elastic components (such as springs or rubber pads), reducing the impact of the equipment on the ground, reducing noise, and preventing the machine body from becoming loose due to long-term vibration.

[0016] Furthermore, the motor is fixedly mounted on the top of the fixed bracket, and a dust cover is provided around the motor and fixedly connected to the front end of the diversion bar.

[0017] The purpose of this design is that, during the use of the equipment, the dust cover around the motor is a closed shell, and its side wall is fixed to the front end of the diverter by buckles. This can prevent dust raised by the blower assembly from entering the motor, thus avoiding dust adhering to the rotor and stator of the motor, which could lead to poor heat dissipation or short circuits. At the same time, the fixing effect of the dust cover further enhances the connection strength between the motor and the machine body, ensuring the long-term efficient operation of the blower assembly.

[0018] This utility model has the following beneficial effects: (1) This utility model sets up a sieve plate, an inclined groove and a dust sieve plate. The three sets of sieve plates are graded according to the size of the sieve holes, realizing the dual function of "grain grading + impurity separation". The inclined groove guides light dust to gather and flow to the dust outlet, solving the problem of dust floating around in the machine body and improving the efficiency of dust directional discharge. The dust sieve plate accurately intercepts small grains at the dust outlet.

[0019] (2) By setting up the rhomboid guide plate, the rhomboid guide plate on the inner wall of the bottom of the machine body guides the large grain particles falling from the upper screen plate to one side discharge hopper through the symmetrical inclined edges, and guides the medium and small grain particles falling from the middle and lower screen plates to the other side discharge hopper. The acute angle structure of the rhomboid guide plate can cut off the accumulation trend of the grain when it falls, ensuring that grains of different sizes quickly enter the corresponding discharge hopper along a fixed path, realizing the orderly discharge of the grain after grading, which is convenient for storage according to particle size.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 As shown, this utility model is a dust removal device for grain storage, including a fixed device 1 and a blower assembly 2. The blower assembly 2 is installed at the front end of the fixed device 1. The fixed device 1 includes a body 101. The top and rear end of the body 101 are provided with an inclined groove 103. A dust outlet 104 is opened on the side of the body 101 near the inclined groove 103. A diversion bar 205 is provided at the front end of the body 101. A motor 203 is provided at the front end of the diversion bar 205. A blower fan 204 is installed at the output end of the motor 203 and corresponds to the dust outlet 104. Dust sieve plates 108 are fixedly installed on the inner walls around the dust outlet 104. Three sets of sieve plates 109 are fixedly connected in parallel on the inner wall of the body 101. The sieve holes of the three sets of sieve plates 109 are arranged sequentially from top to bottom.

[0025] The purpose of this design is that, during the use of the equipment, after the grains enter the machine body 101, they first come into contact with the diversion bar 205 at the front end of the machine body 101. The diversion bar 205 disperses the clumps of grains into small streams through the grid structure, avoiding accumulation and blockage of the subsequent screening path. The dispersed grains fall onto three sets of screen plates 109 that are fixed parallel to each other on the inner wall of the machine body 101. The screen holes of the three sets of screen plates 109 decrease in size from top to bottom: the upper screen plate intercepts large grain particles, the middle screen plate intercepts medium grain particles, and the lower screen plate receives small grain particles. At the same time, light impurities such as dust and debris mixed in the grains can penetrate downwards through the screen holes of each layer due to their small particle size, thus achieving the initial separation of grains and impurities. At this time, the motor 203 at the front end of the machine body 101 starts, driving the blower fan 204 at the output end to rotate at high speed. The airflow generated by the blower fan 204 enters the machine body 101 evenly through the grid gap of the diversion bar 205. Since the weight of dust is much lighter than that of grain, the airflow will blow these light impurities upward, causing them to gather in the inclined groove 103 area at the top and rear end of the machine body 101. The inclination angle of the inclined groove 103 can guide the accumulated dust to flow along the inclined surface to the nearby dust outlet 104. The dust screen 108 on the inner wall of the dust outlet 104 is funnel-shaped, and its mesh only allows dust to pass through. It can intercept the fine grain particles mixed in with the airflow. Finally, the pure dust is filtered by the dust screen 108 and discharged from the dust outlet 104 into the machine body 101, completing the complete separation of dust and grain. The three sets of sieve plates 109 are graded according to the size of the sieve holes, which can separate grains of different particle sizes and allow dust to fully penetrate, realizing the dual function of "grain grading + impurity separation". The inclined groove 103 specifically guides light dust to gather and flow to the dust outlet 104, solving the problem of dust floating around in the machine and improving the efficiency of directional dust discharge. The dust sieve plate 108 accurately intercepts fine grains at the dust outlet 104, preventing grains from being lost with dust during the dust removal process and reducing resource consumption.

[0026] A feed hopper 102 is provided on the top side of the machine body 101 away from the inclined groove 103.

[0027] The purpose of this design is to ensure that, during the use of the equipment, after the grain slides down the inner wall of the feed hopper 102, it falls precisely into the area above the three sets of screen plates 109, ensuring that the material enters the screening stage in a concentrated manner. This provides a continuous and stable material flow for the subsequent grading and separation of the screen plates 109 and the dust removal of the blower assembly 2, preventing the grain from scattering to other areas of the machine body 101 and causing waste or cleaning burden.

[0028] A vibrator 110 is fixedly installed on the outer wall of one side of the bottom of the machine body 101. The vibrator 110 is adjacent to three sets of sieve plates 109.

[0029] The purpose of this setup is that, during the operation of the equipment, after the vibrator 110 on the outer wall of the bottom side of the machine body 101 is started, the high-frequency vibration generated is transmitted through the inner wall of the machine body 101 to the three adjacent sets of sieve plates 109, causing the sieve plates 109 to vibrate slightly in the vertical direction. During the vibration, the grains on the sieve plates 109 are constantly turned over and loosened, making it easier for the dust wrapped in the grains to fall off and be exposed. At the same time, the vibration can break the adsorption force between the grain particles, prevent the sieve holes from being blocked by the grains, and allow dust and fine impurities to pass through the sieve holes smoothly, creating conditions for the blower fan 204 to blow the dust to the inclined groove 103 area, thereby enhancing the synergistic dust removal effect of the sieve plates 109 and the blower assembly 2.

[0030] The bottom surface of the machine body 101 is provided with two sets of discharge hoppers 106, and the inner wall of the bottom surface of the machine body 101 near the two sets of discharge hoppers 106 is provided with rhomboid guide plates 105 respectively.

[0031] The purpose of this design is that, during the use of the equipment, the diamond-shaped guide plate 105 on the inner wall of the bottom surface of the machine body 101 guides the large grain particles falling from the upper screen plate to one side discharge hopper 106 through symmetrical inclined edges, and guides the medium and small grain particles falling from the middle and lower screen plates to the other side discharge hopper 106. The acute angle structure of the diamond-shaped guide plate 105 can cut off the accumulation trend of the grain when it falls, ensuring that grains of different sizes quickly enter the corresponding discharge hopper 106 along a fixed path, realizing the orderly discharge of the graded grains, which is convenient for storage according to particle size.

[0032] The bottom surface of the body 101 is provided with a buffer support 107 at each of the four corners, and a fixed bracket 202 is provided parallel to the front end of the buffer support 107.

[0033] The purpose of this design is that during the operation of the equipment, the vibration of the vibrator 110 and the rotation of the blower 204 will cause the body 101 to shake as a whole. The damping supports 107 around the bottom of the body 101 absorb the vibration energy through built-in elastic components (such as springs or rubber pads), reduce the impact of the equipment on the ground, reduce noise, and prevent the parts of the body 101 from loosening due to long-term vibration.

[0034] The motor 203 is fixedly installed on the top of the fixed bracket 202. The motor 203 is covered with a dust cover 201 and fixedly connected to the front end of the diversion bar 205.

[0035] The purpose of this design is that, during the use of the equipment, the dust cover 201 around the motor 203 is a closed shell, and its side wall is fixed to the front end of the diversion bar 205 by a buckle. This can prevent dust raised by the blower assembly 2 during operation from entering the motor 203, thus avoiding dust adhering to the rotor and stator of the motor 203 and causing poor heat dissipation or short circuit. At the same time, the fixing effect of the dust cover 201 further enhances the connection strength between the motor 203 and the body 101, ensuring the long-term efficient operation of the blower assembly 2.

[0036] During use, grains are fed into the hopper 102 at the top of the machine body 101 and guided by the hopper 102 to fall onto the three sets of screen plates 109. At this time, the vibrator 110 at the bottom of the machine body 101 is started, and the vibration is transmitted to the screen plates 109, causing the grains to turn over on the screen plates 109: large grains are intercepted by the upper screen plate 109, medium grains fall to the middle screen plate 109, and small grains fall to the lower screen plate 109. The mixed dust is separated from the grains due to vibration and penetrates into the internal space of the machine body 101 through the screen holes of each layer. Simultaneously, the motor 203 on the fixed bracket 202 at the front end of the machine body 101 drives the blower fan 204 to rotate. The airflow enters the machine body 101 after being dispersed by the diversion bar 205. Because the dust is light, it is blown upward by the airflow to the inclined groove 103 area at the top end. The inclined groove 103 guides the dust to the dust outlet 104. The dust sieve 108 at the dust outlet 104 filters out any small grains that may be mixed in, allowing only the dust to be discharged. After grading, the clean grains fall from the edges of each layer of screen plate 109, are guided by the bottom diamond-shaped guide plate 105, and are discharged into two sets of discharge hoppers 106. During equipment operation, the damping support 107 absorbs vibration and reduces shaking, and the dust cover 201 outside the motor 203 isolates dust, ensuring that the entire process of "feeding-vibrating screening-airflow dust removal-grading and discharge" is stable and efficient, and completing the dust removal and grading treatment of grains before storage.
