Description

Technical Field

[0001] This utility model relates to the field of cleaning screen technology, and in particular to an environmentally friendly dust removal vibrating cleaning screen. Background Technology

[0002] In agriculture, food processing, and related industries, grain cleaning is a critical step in ensuring product quality and safety. The cleaning process aims to remove various impurities from raw materials, such as stones, straw, dust, and metal fragments, to avoid these impurities negatively impacting subsequent processing stages and to ensure the quality and safety of the final product.

[0003] Patent CN221208909U discloses a vibrating screen that is easy to clean. This patent achieves automatic screen cleaning through an innovative transmission mechanism design. Specifically, the vibrating screen includes a main structure with a transmission mechanism connected to its top, comprising a servo motor, drive shaft, movable ring, sliding column, L-shaped connecting rod, balance frame, and roller. When the servo motor starts, it drives the drive shaft to rotate, causing the sliding column and movable ring to move downwards. This causes the L-shaped connecting rod and balance frame to move synchronously, ultimately allowing the roller to contact and roll along the inclined screen surface. This process not only promotes the material's downward movement but also effectively prevents screen clogging through the continuous scraping of the screen surface by the brushes on the roller, thereby improving screening efficiency. Although the above vibrating screen design performs well in terms of cleaning, it still has some shortcomings in practical applications, especially in grain screening. Due to the crushing and friction of materials, a large amount of dust is usually generated. This dust not only reduces the quality of the working environment and affects worker health but may also become a potential safety hazard.

[0004] Therefore, this patent urgently needs to design an environmentally friendly dust removal vibrating cleaning screen that can effectively collect and treat the generated dust while cleaning materials, ensuring a clean and safe working environment. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] Example 1: Please refer to Figures 1-7An environmentally friendly dust removal vibrating cleaning screen includes a support frame 1. A damping plate 25 is installed at the bottom of the support frame 1. The main function of the damping plate 25 is to absorb and attenuate the vibrations generated during equipment operation, preventing these vibrations from being transmitted to the ground or other supporting structures. A protective shell 2 is fixedly connected to the middle of the support frame 1. The protective shell 2 has a feed inlet at the top, a discharge outlet at the bottom, and a discharge outlet on the side. A feed frame 9 is fixedly connected to the feed inlet. An adjusting plate 12 is rotatably installed inside the feed frame 9. By rotating the adjusting plate 12, its angle can be adjusted to control the opening size of the feed frame 9, thereby controlling the amount of grain fed. The left and right ends of the adjusting plate 12 extend to the outside of the protective shell 2 and are provided with operating handles 13. Anti-slip sleeves 26 are fitted over the operating handles 13. The design of the anti-slip sleeves 26 increases the friction on the surface of the operating handles 13, making the grip more secure for the operator. A retaining device is fitted at the rotatable connection between the adjusting plate 12 and the feed frame 9. The nylon ring 14 is used to increase friction and prevent the adjusting plate 12 from rotating randomly without external force, ensuring stable control of the feed rate. A fixed frame 201 is fixedly connected inside the protective shell 2. A filter screen plate 8 is installed inside the fixed frame 201 for screening grain and removing impurities. In addition, the filter screen plate 8 is arranged at an angle, which helps the grain flow along the screen surface. Connecting plates 3 are fixedly connected to the bottom of the front and rear ends of the filter screen plate 8. Guide rods 4 are fixedly connected to the left and right sides of the front and rear ends of the fixed frame 201. The connecting plate 3 can slide on the guide rod 4. A spring 5 is sleeved on each guide rod 4. The two ends of the spring 5 are respectively connected to the connecting plate 3 and the fixed frame 201, providing an upward restoring force for the connecting plate 3. A motor 6 is installed on one side of the protective shell 2. An eccentric cam 7 is connected to the output shaft of the motor 6. When the motor 6 is started, the eccentric cam 7 rotates and contacts the connecting plate 3, pushing the connecting plate 3 to move upward along the guide rod 4.When the eccentric cam 7 continues to rotate and moves away from the connecting plate 3, the connecting plate 3, together with the filter screen plate 8, returns to its initial position under the action of the spring 5, thereby achieving the up-and-down vibration effect of the filter screen plate 8, promoting uniform grain distribution and accelerating the sieving process. A dust collection hood 10 is installed on the top of the protective shell 2, and the dust collection hood 10 communicates with the interior of the protective shell 2. The dust collection hood 10 has three dust collection chambers, each equipped with a dust collection fan 1001. The dust collection chambers are connected to a common exhaust pipe 11. A dust collection box 110 is installed at the lower part of the support frame 1. The top of the dust collection box 110... Connected to the end of the exhaust pipe 11, the dust collection box 110 is used to collect dust and other light impurities in the air, ensuring a clean working environment and reducing air pollution. Two sealing doors 1101 are hinged to the dust collection box 110, allowing for the cleaning of accumulated dust inside, ensuring continuous operation of the device. A dust filter 1102 is installed inside the dust collection box 110 near the exhaust pipe 11. The dust collection box 110 has two partitions 1103, and multiple air vents 1104 are located on the side of the dust collection box away from the exhaust pipe 11.

[0030] When using this device, the operator first holds the operating handle 13 to adjust the angle of the adjusting plate 12, thereby controlling the size of the opening of the feed frame 9 to adapt to different feeding speed requirements. Then, the grain to be screened is put into the feed frame 9, the motor 6 is started, and the eccentric cam 7 begins to rotate, periodically squeezing the connecting plate 3, causing the filter screen plate 8 to vibrate up and down. This vibration helps the grain to be evenly distributed on the screen surface and accelerates the screening process. The qualified grain after screening is discharged from the discharge port, while dust and heavier impurities are discharged from the discharge outlet. During the entire screening process, dust and other light impurities are generated due to the friction of the grain. At this time, the dust suction fan 1001 in the dust suction hood 10 works to suck these suspended dust particles into the dust suction chamber, and then through the exhaust pipe 1 1. The dust is discharged into the dust collection box 110. After entering the dust collection box 110, the dust is first filtered by the dust filter 1102, so that the large-diameter dust is left in the gap between the dust collection box 110 and the dust filter 1102. The filtered airflow enters the gap between the dust filter 1102 and the partition 1103. Under the action of the two partitions 1103 and the dust collection box 110, the flow path of the gas and dust is "S" shaped, which slows down the gas flow speed. Small dust particles mixed in the gas fall into the dust collection box 110. Then the gas is discharged through the air outlet 1104, thereby reducing the content of dust particles in the discharged gas, achieving the purpose of environmentally friendly dust removal, ensuring the cleanliness of the working environment, and reducing the threat to workers' health and pollution to the surrounding environment.

[0031] Example 2: Based on Example 1, please refer to... Figure 8 and Figure 9The fixed frame 201 has a first dustproof plate 17 slidably mounted on its left side, and the protective shell 2 has a second dustproof plate 18 slidably mounted on its left side. A slot is provided at the position of the support frame 1 above the second dustproof plate 18. When the second dustproof plate 18 moves upward, it can be locked into the slot for fixation. A connecting plate 16 is slidably mounted on the first dustproof plate 17 and the second dustproof plate 18. Square slots are opened at the same position on the sides of the fixed frame 201 and the protective shell 2 to guide the sliding of the connecting plate 16. One end of the connecting plate 16 passes through the two square slots and enters the interior of the fixed frame 201, and a brush 15 is installed on it. The brush 15 is also arranged at an angle with the filter screen plate 8. The angled design of the brush 15 helps to better fit the surface of the screen plate and improve the cleaning effect. A handle 19 is fixed to the other end of the connecting plate 16 to facilitate the operator's cleaning operation.

[0032] When completing the screening and cleaning the filter screen plate 8, hold the handle 19 and pull down the connecting plate 16 to move the second dustproof plate 18 down out of the slot. Continue to pull down the connecting plate 16 so that the brush 15 descends to the position of contact with the surface of the filter screen plate 8. Then push the connecting plate 16 to move it to the right. The brush 15 will then thoroughly clean the surface of the filter screen plate 8, effectively removing dust and debris attached to the surface, maintaining the cleanliness of the filter screen plate 8, and preventing the screen holes from clogging. After cleaning, pull the connecting plate 16 to the left to return it to its initial position, and pull the connecting plate 16 upward to move it upward and re-lock it into the slot on the support frame 1, thereby fixing the connecting plate 16 and preventing the brush 15 from affecting the operation of the filter screen plate 8.

[0033] Please see Figure 10 and Figure 11 The protective shell 2 is equipped with a collection frame 20 at the discharge port for collecting the screened debris and swept dust. A cover 21 is hinged to the collection frame 20, and a pull rod 22 is fixed to the cover 21. A pull rope 23 is wound around the pull rod 22. One end of the pull rope 23 is connected to an insertion rod 24, and the other end is connected to the collection frame 20. The collection frame 20 is provided with a slot that matches the insertion rod 24.

[0034] During screening and cleaning operations, larger debris falling from the filter screen plate 8, as well as dust and other light impurities generated during the cleaning process, fall from the discharge port into the collection frame 20 for centralized collection. This prevents debris from scattering in the work area, reduces cleaning difficulty, maintains a clean working environment, and facilitates subsequent unified processing or recycling. When it is necessary to clean the debris in the collection frame 20, the operator first pulls out the insert rod 24 to release the fixation of the cover 21. At this time, the cover 21, no longer constrained by the limit rope, can be opened freely through the hinge point. Then, the operator grabs the pull rod 22 and pulls the cover 21 to rotate it around the hinge point, thereby fully opening the cover 21 and exposing the debris inside the collection frame 20. The operator then discharges the debris from the collection frame 20. After cleaning, the cover 21 is closed again, and the insert rod 24 is inserted into the slot on the collection frame 20 to fix the cover 21 again with the limit rope, ensuring that it remains closed during equipment operation and preventing debris leakage.

[0035] The above embodiments are provided for those skilled in the art to implement or use the present invention. Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
