Description

Technical Field

[0001] The present application relates to the technical field of vacuum loaders, and in particular to a vacuum loader with low material damage. Background Art

[0002] A vacuum loader, also known as a vacuum conveyor, is a dust-free, closed pipeline conveying equipment that uses vacuum suction to transport granular and powdered materials. It uses the pressure difference between the vacuum and the ambient space to form gas flow in the pipeline, drive the movement of materials, and thus complete the material transportation.

[0003] In the existing technology, the feed pipe of the vacuum loader is set on the side of the tank body, and the angle is generally set perpendicular to the tank body. During actual use, when the material enters the tank body, it is easy to collide with the corresponding side wall of the tank body under the action of inertia, thereby breaking the ceramic particles of the coating material, affecting the product quality, and not meeting the use requirements.

[0004] Therefore, it is urgent to improve the existing vacuum feeder. Utility Model Content

[0005] The purpose of this application is to provide a vacuum loader with less damage to materials to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present application provides a vacuum feeder with less material damage, which adopts the following technical solutions:

[0007] A vacuum loader with low material damage, including a sealed container, a vacuum generator, a filter and a discharge assembly, the filter is installed on the top of the sealed container, the vacuum generator is installed on the top of the filter, and the discharge assembly is installed on the bottom of the sealed container. The sealed container consists of two parts, the upper part is a lower material bin, and the lower part is a lower material hopper. The filter is connected to the top of the lower material bin, the cross-section of the lower material bin is circular, and the side of the lower material bin is connected to a suction pipe, and the suction pipe is arranged perpendicular to the tangent of the circle of the lower material bin.

[0008] Preferably, a deceleration chamber is provided at a position of the suction pipe close to the lower hopper, and the diameter of the deceleration chamber is larger than the diameter of the suction pipe.

[0009] By adopting the above technical solution and providing a deceleration chamber, according to fluid mechanics, when an object enters a large-diameter pipeline from a small-diameter pipeline, the pressure and flow rate will become smaller, thereby reducing the impact force of the coating material particles touching the inner wall of the lower silo.

[0010] Preferably, in order to prevent the material from bridging in the lower hopper, a vibrator is installed on the side wall of the lower hopper.

[0011] Preferably, a dust cover is fixed to the bottom of the sealed container, and the dust cover is arranged on the surface of the lower hopper. The discharge assembly includes a rotating cylinder and a sealing door. The rotating cylinder is fixed on the dust cover, and the sealing door is installed on the piston rod of the rotating cylinder and is driven by the rotating cylinder to abut against the bottom of the lower hopper.

[0012] By adopting the above technical solution and providing a dustproof cover, it is easy to connect with the material receiving mechanism, and material unloading is more convenient without contamination of the material.

[0013] The side of the dust cover is also connected with a ventilation pipe, and the surface of the ventilation pipe is covered with a mesh cover.

[0014] To sum up, the present application includes at least one of the following beneficial technical effects: the vacuum loader with low material damage can make the ceramic particles entering the lower hopper rotate along the inner wall of the lower hopper under the action of inertia by setting the suction tube in the vertical direction of the circular tangent of the lower hopper, and slide into the lower hopper under the action of gravity, instead of directly colliding with the side wall of the lower hopper, thereby reducing the impact and protecting the ceramic particles from breakage caused by impact, thereby improving product quality and yield.

[0018] The following is combined with Figure 1-2 This application is described in further detail.

[0019] The present application discloses a vacuum feeder with little damage to materials. Figure 1-2 , including a sealed container 1, a vacuum generator 2, a filter 3 and a discharge assembly. The filter 3 is installed on the top of the sealed container 1, the vacuum generator 2 is installed on the top of the filter 3, and the discharge assembly is installed at the bottom of the sealed container 1. The sealed container 1 consists of two parts, the upper part is a lower hopper 11, and the lower part is a lower hopper 12. In order to avoid bridging of materials in the lower hopper 12, a vibrator 4 is installed on the side wall of the lower hopper 12. The filter 3 is connected to the top of the lower hopper 11. The cross-section of the lower hopper 11 is circular. The side of the lower hopper 11 is connected to a suction pipe 5, and the suction pipe 5 is arranged perpendicular to the tangent of the circle of the lower hopper 11.

[0020] Reference Figure 1 A deceleration chamber 51 is provided at a position of the suction pipe 5 near the lower hopper 11 , and the diameter of the deceleration chamber 51 is larger than the diameter of the suction pipe 5 .

[0021] By providing the deceleration chamber 51 , according to fluid mechanics, when an object enters a pipeline with a large diameter from a pipeline with a small diameter, the pressure and flow rate will decrease, thereby reducing the impact force of the ceramic particles hitting the inner wall of the lower hopper 11 .

[0022] Reference Figure 2 A dust cover 6 is fixed to the bottom of the sealed container 1, and the dust cover 6 is arranged on the surface of the lower hopper 12. The discharge assembly includes a rotary cylinder 7 and a sealing door 8. The rotary cylinder 7 is fixed on the dust cover 6. The sealing door 8 is installed on the piston rod of the rotary cylinder 7 and is driven by the rotary cylinder 7 to abut against the bottom of the lower hopper 12. The side of the dust cover 6 is also connected to a ventilation pipe, and the surface of the ventilation pipe is covered with a mesh cover.

[0023] By providing the dust cover 6, it is easy to connect with the material receiving mechanism, and the material is more convenient to unload without being contaminated.

[0024] The implementation principle of a vacuum loader with low material damage in the embodiment of the present application is as follows:

[0025] The operation of the vacuum generator 2 forms a negative pressure in the sealed container 1, and the material is sucked into the lower hopper 11 through the suction pipe 5. By arranging the suction pipe 5 in the vertical direction of the tangent line of the circle of the lower hopper 11, the material entering the lower hopper 11 can rotate along the inner wall of the lower hopper 11 under the action of inertia and slide into the lower hopper 11 under the action of gravity, instead of directly colliding with the side wall of the lower hopper 11, thereby reducing the impact and protecting the ceramic particles.

[0026] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
