Description

Technical Field

[0001] This utility model relates to the field of peanut conveyor belts, and in particular to a peanut conveyor belt material discharge dust removal device. Background Technology

[0002] Currently, in the conveying process of granular materials such as peanuts, dust removal devices are usually installed above or at the end of the conveyor belt to control dust pollution. However, most existing dust removal equipment uses a dust suction hood installed at the top of the conveyor belt. This structure is difficult to effectively capture dust generated by the impact and tumbling of materials at the drop point, resulting in poor dust removal effect. There is also the practice of adding a dust suction device at the end of the conveyor belt, but this often has problems such as complex structure, inconvenient installation, and difficult maintenance. In addition, it is easy for the connection to become loose or the seal to be poor due to poor material flow or vibration, which affects the dust removal efficiency and equipment stability.

[0003] Furthermore, traditional devices lack sufficient fixation and positioning of the screening components, making them prone to displacement. They also lack effective end-of-line dust control structures, hindering the thorough separation of dust and materials. Additionally, their shock absorption capacity is limited when subjected to vibration or impact, affecting the overall stability and reliability of operation. Therefore, there is an urgent need for a material discharge dust collector that is structurally sound, easy to install, highly efficient in dust removal, and stable in operation, to address the technical problems of poor dust removal efficiency, complex installation, easy clogging, and inconvenient maintenance in existing technologies. Utility Model Content

[0004] The main purpose of this utility model is to provide a peanut conveyor belt dust removal device to solve the technical problems of poor dust removal effect, complicated installation, easy clogging, and inconvenient maintenance.

[0025] like Figure 1-5 As shown, a peanut conveyor belt dust removal device is provided. A dust removal hopper 3 is provided below the discharge port of the conveyor belt 1. An inclined screen plate 2 is provided at the opening of the dust removal hopper 3. The bottom of the dust removal hopper 3 has a conical structure. The conical opening at the bottom of the dust removal hopper 3 is connected to the dust hopper 8 through a dust suction fan 6.

[0026] The upper part of the rear surface of the dust collector 3 is connected to the lower part of the conveyor belt 1 via an L-shaped mounting plate 10. The front two sides of the dust collector 3 are connected to the lower part of the support frame 11 via inclined support rods 9. Multiple springs 902 are provided between the end of the support rods 9 and the dust collector 3.

[0027] When the device is in use, the peanuts conveyed on the conveyor belt 1 are discharged from the discharge port. During the falling process, the peanuts enter the dust collection hopper 3 located below the discharge port and first fall on the inclined screen plate 2 set at the opening above the dust collection hopper 3. Due to the inclined angle of the screen plate 2, the peanuts slide or roll down along the screen plate 2 under the action of gravity. The dust attached to the surface of the peanuts or falling with the peanuts settles down through the gaps of the screen plate 2 or directly through the space above the screen plate 2 and falls into the bottom area of ​​the dust collection hopper 3.

[0028] The bottom of the dust collection hopper 3 is designed with a conical structure, which helps dust to gather towards the center. The dust collection fan 6 is connected to the conical opening at the bottom of the dust collection hopper 3 through a pipe. After the dust collection fan 6 is turned on, a negative pressure is formed inside the dust collection hopper 3, which draws the settled dust out from the conical opening and transports it to the dust hopper 8 through the air duct for centralized collection, thereby achieving effective dust removal during the peanut feeding process.

[0029] The installation structure of the device is as follows: the upper part of the rear surface of the dust collector 3 is fixedly connected to the lower frame of the conveyor belt 1 by an L-shaped mounting plate 10, providing the main support and positioning; the two sides of the front of the dust collector 3 are connected to the lower part of the independent support frame 11 by inclined support rods 9. Multiple springs 902 are set between the end of the support rods 9 and the dust collector 3 to form a connection with a certain degree of elasticity. The triangular support structure with elastic support at the front not only ensures the overall stability of the dust collector 3 installation, but also buffers the impact of falling peanuts or the vibration caused by equipment operation through the springs 902, thereby improving the stability and service life of the device.

[0030] By placing the dust removal device below the discharge port of conveyor belt 1, dust can be removed directly at the key location where peanuts fall. Compared with the traditional method of installing dust collection equipment at the top or tail of the conveyor belt, it can more effectively capture the dust raised during the fall, significantly improving the dust removal efficiency and effect.

[0031] The sieve plate 2 is used to achieve the initial separation of peanuts and dust. It utilizes the combined effect of gravity and wind power, has a simple structure, and requires no additional power. The whole device is supported by an L-shaped mounting plate 10 and a support rod 9 with a spring 902 to form a triangular support. The installation structure is stable and has a shock absorption function, which simplifies the installation process and reduces the complexity of installation. At the same time, the conical bottom design facilitates the smooth discharge and collection of dust, avoids dust accumulation, and ensures that the dust suction fan 6 works continuously and efficiently. The whole system has a compact structure and is easy to maintain. It is particularly suitable for dust control during the conveying and dropping of granular materials such as peanuts.

[0032] In the preferred embodiment, the end of the support rod 9 is connected to the lower part of the support frame 11 via the second fixing seat 904, the dust collector 3 is provided with the first fixing seat 903, the end of the support rod 9 is provided with the support plate 901, and multiple springs 902 are arranged between the support plate 901 and the first fixing seat 903.

[0033] The end of the support rod 9 is connected to the lower part of the support frame 11 through the second fixing seat 904 to ensure that the support rod 9 is firmly fixed on the support frame 11; the dust collector 3 is provided with a first fixing seat 903, and the other end of the support rod 9 is provided with a support plate 901. Multiple springs 902 are installed between the support plate 901 and the first fixing seat 903 to form an elastic connection structure.

[0034] In operation, peanuts fall from the discharge port of conveyor belt 1 into dust hopper 3 and land on the inclined screen plate 2. The peanuts slide down the screen plate 2 and are discharged, while the dust passes through the screen plate 2 or falls into the conical area at the bottom of dust hopper 3 under gravity. The dust suction fan 6 uses negative pressure to suck the dust from the conical opening and transport it to the dust hopper 8 for centralized collection. Regarding the support structure, the rear of dust hopper 3 is connected to the lower part of conveyor belt 1 via an L-shaped mounting plate 10, while the front is connected to the support frame 11 via support rods 9 on both sides. One end of the support rod 9 is fixed to the support frame 11 via a second fixed seat 904, and the other end is elastically supported by multiple springs 902 between the support plate 901 and the first fixed seat 903. This design allows the entire dust hopper 3 to maintain a stable triangular structure while effectively absorbing the impact of falling peanuts and vibrations generated by equipment operation through the springs 902, reducing structural stress, preventing loosening, and improving operational stability and device durability.

[0035] In the preferred embodiment, the L-shaped mounting plate 10 is made of steel plate or stainless steel. The thickness of the L-shaped mounting plate 10 is 5-8 mm.

[0036] A vibration device 12 is also provided on one side of the dust collection hopper 3.

[0037] The L-shaped mounting plate 10 is made of steel plate or stainless steel and its thickness is designed to be 5-8mm. This thickness ensures that the mounting plate 10 has sufficient structural strength to stably support the rear of the dust collector 3, while also giving it a certain degree of flexibility or elastic deformation capability.

[0038] A vibration device 12 is added to one side of the dust collection hopper 3. When the peanuts pass through the screen plate 2 for dust removal, if the material accumulates in the screen plate 2 or the dust collection hopper 3 and the material discharge is not smooth, the vibration device 12 can be activated. The vibration will cause the screen plate 2 and the dust collection hopper 3 to vibrate, thereby accelerating the sliding of the peanuts and the separation of dust, effectively improving the material discharge efficiency and dust removal effect.

[0039] At this time, the multiple springs 902 at the end of the support rod 9 not only play a role in buffering and shock absorption, but also produce a synergistic effect with the vibration frequency when the vibration device 12 is working, enhancing the vibration transmission effect of the entire dust collector 3 and making the vibration more evenly distributed throughout the dust collector 3. The 5-8mm thick steel plate or stainless steel material used in the L-shaped mounting plate 10 has a certain elastic deformation capacity, which can produce slight deformation during vibration. Together with the elastic connection of the support rod 9, it forms an elastic support system, thereby cooperating with the vibration device 12 to achieve more efficient vibration feeding and avoid vibration attenuation or structural damage caused by rigid connection.

[0040] In the preferred embodiment, the dust collector hopper 3 has raised baffles 301 on both sides, and the sieve plate 2 is positioned between the two baffles 301. The dust collector hopper 3 has a raised mounting platform 302 inside its opening, and the sieve plate 2 is fixed to the mounting platform 302 by multiple screws. The lower surface of the upper end of the sieve plate 2 has a raised positioning strip 202, and the mounting platform 302 has a positioning groove 303 that mates with the positioning strip 202. The sieve plate 2 is positioned in the positioning groove 303 by the positioning strip 202.

[0041] The dust collector hopper 3 has raised baffles 301 on both inner walls, forming a space between the two baffles 301 for installing the screen plate 2. The screen plate 2 is positioned between these two baffles 301, serving as a limit and support to prevent displacement in the width direction. Inside the opening of the dust collector hopper 3, there is an annular or partially raised mounting platform 302. The screen plate 2 is placed entirely on this mounting platform 302 and is securely fixed to it from above or the side with multiple screws, ensuring that the screen plate 2 will not loosen or fall off due to material impact or vibration during use. To further improve installation accuracy and stability, a raised positioning strip 202 is provided on the lower surface of the upper end of the screen plate 2, and a matching positioning groove 303 is machined at the corresponding position on the mounting platform 302. During installation, the positioning strip 202 of the screen plate 2 is aligned and embedded into the positioning groove 303 to achieve precise positioning of the screen plate 2 in the length direction, preventing it from sliding back and forth.

[0042] The screen plate 2 is laterally limited by the baffle 301, supported by the mounting platform 302, and fastened with screws. Simultaneously, the positioning strip 202, in cooperation with the positioning groove 303, achieves precise positioning in the front-to-back direction, ensuring the screen plate 2 maintains stable operation even under complex working conditions. When cleaning or replacing the screen plate 2, the fixing screws can be removed, and the positioning strip 202 can be pulled out of the positioning groove 303 for quick disassembly and maintenance.

[0043] In the preferred embodiment, a raised dust-blocking strip 201 is provided on the lower upper surface of the sieve plate 2, and the dust-blocking strip 201 has a fan-shaped cross-section.

[0044] A raised dust-blocking strip 201 is provided on the lower upper surface of the screen plate 2. The cross-section of the dust-blocking strip 201 is designed as a fan-shaped structure, that is, its cross-section is arc-shaped or approximately semi-circular, with a smooth, raised front end and gradually tapering towards the rear end. In use, after peanuts fall from the discharge port of the conveyor belt 1, they land on the inclined screen plate 2 and roll or slide along the surface of the screen plate 2 towards the lower end under the action of gravity, eventually passing over the dust-blocking strip 201 and being discharged smoothly. During this process, some of the fine dust adhering to the surface of the peanuts or falling with the peanuts settles or is carried away by the airflow when passing through the surface of the screen plate 2. However, dust that is still suspended or moving with the material flow near the end of the screen plate 2 is blocked by the dust-blocking strip 201 when it reaches the lower end of the screen plate 2. Because the dust-blocking strip 201 has a certain height and a fan-shaped cross-section, it can effectively intercept the airflow and dust particles flowing along the surface of the screen plate, causing them to change direction or settle, thereby preventing this part of the dust from continuing to fly forward or being discharged with the peanuts, thus improving dust removal efficiency.

[0045] In the preferred embodiment, the dust outlet 304 below the dust hopper 3 is connected to one end of the first dust suction pipe 5 with a flexible structure, and the other end of the first dust suction pipe 5 is connected to the dust suction fan 6.

[0046] The vacuum cleaner 6 is connected to the dust hopper 8 through the second vacuum pipe 7.

[0047] Below the conical opening at the bottom of the dust collection hopper 3 is a dust outlet 304. This dust outlet 304 is connected to one end of a flexible first suction pipe 5, and the other end of the first suction pipe 5 is connected to the air inlet of the suction fan 6, forming a dust collection channel from the dust collection hopper 3 to the suction fan 6. The air outlet of the suction fan 6 is connected to the dust hopper 8 through a second suction pipe 7, ultimately guiding the dust-laden airflow into the dust hopper 8 to achieve dust separation and collection. In use, after the peanuts are sieved by the sieve plate 2 in the dust collection hopper 3, the separated dust falls to the bottom of the dust collection hopper 3. After the suction fan 6 is started, a negative pressure is formed inside the dust collection hopper 3, and the dust is sucked in through the dust outlet 304, transported to the suction fan 6 through the first suction pipe 5, and then discharged into the dust hopper 8 through the second suction pipe 7. The dust settles and is collected in the dust hopper 8 due to the reduced flow rate.

[0048] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
