Description

Technical Field

[0001] This utility model relates to the technical field of pneumatic conveying equipment for mixing materials, and in particular to an environmentally friendly pneumatic conveying equipment for mixing materials. Background Technology

[0002] Pneumatic conveying equipment is a fluidization technology device that uses airflow to transport particulate materials in a closed pipeline. It is mainly used in casting, metallurgy, chemical industry, building materials, and food processing. Its core structure includes components such as a receiver, conveying pipe, separator, and blower. According to the working pressure, it is divided into suction conveying (low / high vacuum), pressure conveying (high / low pressure), and pulse conveying systems.

[0003] When pneumatic conveying equipment is used to transport powder in the brick-making industry, the high-pressure airflow generated by the high-pressure blower pushes the powder through the conveying process. When passing through the bend of the conveying pipe, a small amount of powder will settle at the bend and accumulate inside the conveying pipe, resulting in a loss of powder transport volume. Over time, it may also cause blockage of the conveying pipe, affecting the transport of food powder. Utility Model Content

[0004] This utility model discloses an environmentally friendly pneumatic conveying equipment for mixing materials, which mainly solves the problem that when traditional pneumatic conveying equipment conveys powder to a bend, a small portion of the powder tends to settle at the bend and accumulate inside the conveying pipe.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides an environmentally friendly pneumatic conveying equipment for mixing materials, including a silo. The top of the silo is provided with a feeding hopper, and the bottom is connected in sequence with a first conveying pipe, a second conveying pipe and a third conveying pipe. The other end of the third conveying pipe is connected to a mixing tank. The silo is provided with a compressed air inlet pipe and a constant pressure pipe. The second conveying pipe has an angle with the first and third conveying pipes. Anti-blocking devices are connected between the second conveying pipe and the first and third conveying pipes.

[0007] The anti-clogging device includes a first connecting plate and a second connecting plate for connection. The first connecting plate and the second connecting plate have an included angle. An elastic hose is connected between the first connecting plate and the second connecting plate. An anti-clogging component is connected to the first connecting plate and the second connecting plate by a bracket. The anti-clogging component is disposed on the outside of the elastic hose. The anti-clogging component includes a rotating wheel driven by a motor. Multiple connecting frames are evenly arranged on the outer circumference of the rotating wheel. Anti-clogging elements for impacting the elastic hose are provided on the connecting frames.

[0008] In one embodiment, the anti-blocking component is rotatably connected to the connecting frame.

[0009] In one embodiment, the anti-clogging component is a cylindrical structure.

[0010] In one embodiment, the diameter of the middle section of the anti-blocking component gradually increases towards both ends, so that the surface of the anti-blocking component forms an arc-shaped structure.

[0011] In one embodiment, the elastic hose is provided with a thickened protective layer at the point of impact.

[0012] In one embodiment, the rotating wheel is provided with a plurality of hollow holes.

[0013] In one embodiment, both the first connecting plate and the second connecting plate are respectively provided with a first connecting pipe and a second connecting pipe.

[0014] The advantages or beneficial effects of the above technical solution include at least the following: When conveying the mixed powder, the powder is first put into the silo through the feed hopper. Compressed air is introduced through the inlet pipe to form high-pressure gas in the silo. The silo is then opened by the valve at the bottom of the silo, and the powder in the silo is quickly conveyed by the high-pressure gas sequentially through the first conveying pipe, the second conveying pipe, and the third conveying pipe to the mixing tank. When passing through the anti-blocking device, in order to prevent the powder from blocking at the bend, the motor of the anti-blocking component drives the rotating wheel to rotate through the setting of the elastic hose. The rotating wheel drives the connecting frame and the anti-blocking component, causing the anti-blocking component to hit the elastic hose. After the elastic hose is deformed, it returns to its original shape due to its elasticity, which can knock up the powder that has settled, thereby achieving the anti-blocking effect.

[0035] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0036] See Figure 1 , Figure 2 , Figure 4 and Figure 5 The present invention provides an environmentally friendly pneumatic conveying device for mixing materials, including a silo 1, a feeding hopper 2 at the top of the silo 1, and a first conveying pipe 3, a second conveying pipe 4 and a third conveying pipe 5 connected sequentially at the bottom. The other end of the third conveying pipe 5 is connected to a mixing tank 7. The silo 1 is provided with a compressed air inlet pipe 11 and a constant pressure pipe 12. The second conveying pipe 4 has an angle with the first conveying pipe 3 and the third conveying pipe 5. Anti-blocking devices 6 are connected between the second conveying pipe 4 and the first conveying pipe 3 and the third conveying pipe 5.

[0037] The anti-blocking device 6 includes a first connecting plate 61 and a second connecting plate 62 for connection. The first connecting plate 61 and the second connecting plate 62 have an included angle. An elastic hose 63 is connected between the first connecting plate 61 and the second connecting plate 62. An anti-blocking component 65 is connected to the first connecting plate 61 and the second connecting plate 62 by a bracket 64. The anti-blocking component 65 is disposed on the outside of the elastic hose 63. The anti-blocking component 65 includes a rotating wheel 652 driven to rotate by a motor 651. A plurality of connecting frames 653 are evenly arranged on the outer circumference of the rotating wheel 652. An anti-blocking element 654 for impacting the elastic hose 63 is provided on the connecting frame 653.

[0038] Using the above structure, when conveying the mixed powder, the powder is first put into the silo 1 through the feed hopper 2. Compressed air inlet pipe 11 is used to introduce high-pressure gas, so that high-pressure air is formed in the silo 1. The powder in the silo 1 is then quickly conveyed by the high-pressure gas through the first conveying pipe 3, the second conveying pipe 4 and the third conveying pipe 5 to the mixing tank 7. When passing through the anti-blocking device 6, in order to prevent the powder from blocking at the bend, the motor 651 of the anti-blocking component 65 drives the rotating wheel 652 to rotate through the elastic hose 63. The rotating wheel 652 drives the connecting frame 653 and the anti-blocking component 654, so that the anti-blocking component 654 hits the elastic hose 63. After the elastic hose 63 is deformed, it returns to its original shape due to its elasticity, which can knock up the powder that has settled, thereby achieving the anti-blocking effect.

[0039] In one embodiment, see Figure 5 The anti-clogging component 654 is rotatably connected to the connecting frame 653. The anti-clogging component 654 has pivots at both ends, and the connecting frame 653 has through-holes corresponding to these pivots. By having the pivots pass through the through-holes, the anti-clogging component 654 can be rotatably connected to the connecting frame 653. In practical applications, the rotatable connection of the anti-clogging component 654 to the connecting frame 653 ensures that it rotates when it impacts the elastic hose 63, thereby reducing friction between the anti-clogging component 654 and the elastic hose 63 and improving the protection of the elastic hose 63.

[0040] The anti-clogging component 654 has a cylindrical structure. In practical applications, the cylindrical structure of the anti-clogging component 654 facilitates its impact on the elastic hose 63.

[0041] The diameter of the anti-clogging component 654 gradually increases from the middle section to both ends, forming an arc-shaped structure on its surface. In practical applications, by adjusting the diameter of the anti-clogging component 654, the distance between each position of its arc-shaped structure and the elastic hose 63 is the same. This ensures that when the anti-clogging component 654 impacts the elastic hose 63, the impact force on the elastic hose 63 is similar, thus preventing uneven force on the elastic hose 63 and ensuring effective unblocking.

[0042] In one embodiment, see Figure 2 , Figure 3 and Figure 4 The flexible hose 63 has a thickened protective layer 631 at the impact point. In practical applications, by providing the thickened protective layer 631 on the flexible hose 63, the protection strength at the impact point of the anti-blocking component 654 can be improved, preventing that position from being easily worn down by impact.

[0043] In one embodiment, see Figure 5 In order to reduce the weight of the rotating wheel 652 and reduce the power required to drive the rotating wheel 652 to rotate, multiple hollow holes are provided in the rotating wheel 652.

[0044] In one embodiment, see Figure 3 Both the first connecting plate 61 and the second connecting plate 62 are respectively provided with a first connecting pipe 611 and a second connecting pipe 621. In practical applications, the first connecting pipe 611 and the second connecting pipe 621 facilitate the connection of the first conveying pipe 3, the second conveying pipe 4 and the third conveying pipe 5. The connection can be made by butt joint, flange connection, welding or threaded connection.
