Abstract
Description
Technical Field
[0001] This utility model relates to the field of pneumatic conveying chamber technology, and in particular to a pneumatic conveying chamber with a flow-aiding function. Background Technology
[0002] In the industrial production field, pneumatic conveying technology is widely used in the conveying of powder and granular materials in industries such as chemical, food, and mining due to its advantages such as simple equipment structure, small footprint, and ability to achieve long-distance conveying.
[0003] However, in actual conveying operations, materials often possess a certain degree of viscosity, and as they flow within the conveying hopper, they experience friction and adsorption against the hopper walls. This can easily lead to material accumulation, bridging, or even blockage on the inner walls of the pump. This not only severely reduces material flowability, causing a significant drop in conveying efficiency and affecting production continuity, but also can cause the accumulated material to deteriorate and harden due to prolonged retention, thus contaminating subsequently conveyed materials and adversely affecting product quality.
[0004] To address these issues, existing technologies typically employ methods such as increasing the airflow pressure, installing agitation devices, or lining the silo walls with smooth materials. However, increasing airflow pressure significantly increases energy consumption and may cause excessive impact on the materials, damaging their physical properties. Adding agitation devices complicates the equipment structure, increases maintenance costs, and has limited agitation effectiveness for highly viscous or easily agglomerated materials. While lining with smooth materials can reduce initial adhesion between the material and the silo walls to some extent, the material surface is prone to wear after long-term use, and the adhesion problem will gradually become more prominent, making it difficult to fundamentally prevent the formation of stubborn deposits. Utility Model Content
[0005] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a pneumatic conveying chamber with a flow-aiding function, which solves the problem of materials easily adhering to the inner wall of the conveying chamber, causing stubborn accumulation, and also solves the problem of low material flowability.
[0006] This utility model also provides a pneumatic conveying chamber with the aforementioned flow-aiding function, comprising: a chamber pump; a plurality of guide plates fixedly connected to the inner wall of the chamber pump; the guide plates being distributed in a ring around the axis of the chamber pump; a micro ultrasonic vibrator being arranged between the guide plates; a material trough being arranged between the guide plates and the chamber pump; a nozzle being arranged on the material trough; a main connecting pipe fixedly connected to the outer side of the chamber pump; a secondary connecting pipe fixedly connected to the side surface of the main connecting pipe; a discharge pipe fixedly connected to the end of the secondary connecting pipe away from the main connecting pipe; and the discharge pipe being fixedly connected to the lower surface of the chamber pump. Through the above structure, high-frequency micro-vibration breaks the adhesion between the material and the wall surface, and in conjunction with airflow, "peels" and activates the material, preventing the formation of stubborn accumulation, causing the material to flow towards the discharge pipe, increasing material flowability, and improving conveying efficiency.
[0007] According to the present invention, a pneumatic conveying chamber with a flow-aiding function is provided with an air compressor at the end of the main connecting pipe away from the chamber pump. The above structure facilitates the injection of air into the main connecting pipe through the air compressor.
[0008] According to the present invention, a pneumatic conveying chamber with a flow-aiding function is provided with a one-way valve at the end of the secondary connecting pipe near the discharge pipe. Through the above structure, materials are prevented from entering the secondary connecting pipe.
[0009] According to the present invention, a pneumatic conveying silo with a flow-aiding function is provided, wherein a feed pipe is fixedly connected to the silo pump, the feed pipe passes through the silo pump and extends into the silo pump, and the above structure facilitates the entry of materials into the silo pump.
[0010] According to the present invention, a pneumatic conveying chamber with a flow-aiding function is provided in the chamber pump, the vent pipe is fixedly connected to the inner wall of the chamber pump, and a nozzle is fixedly connected to the side surface of the vent pipe. Through the above structure, it is convenient to spray air out through the nozzle.
[0011] According to the present invention, a pneumatic conveying chamber with a flow-aiding function is provided in the discharge pipe, and the discharge pipe is connected to the auxiliary connecting pipe. Through the above structure, it is convenient to spray air at the discharge pipe to increase the flowability of materials.
[0012] Beneficial effects:

[0022] Reference Figure 1-4 This utility model discloses a pneumatic conveying chamber with a flow-aiding function, comprising: a chamber pump 1; a plurality of guide plates 8 fixedly connected to the inner wall of the chamber pump 1; the guide plates 8 being arranged in a ring around the axis of the chamber pump 1; a miniature ultrasonic vibrator 11 disposed between the guide plates 8; a material trough 13 disposed between the guide plates 8 and the chamber pump 1; a nozzle 10 disposed on the material trough 13; a main connecting pipe 5 fixedly connected to the outer side of the chamber pump 1; an air compressor 4 disposed at the end of the main connecting pipe 5 away from the chamber pump 1; and a secondary air compressor 4 fixedly connected to the side surface of the main connecting pipe 5. A one-way valve 7 is provided at one end of the connecting pipe 6 near the discharge pipe 2. The discharge pipe 2 is fixedly connected at the end of the auxiliary connecting pipe 6 away from the main connecting pipe 5. The discharge pipe 2 is fixedly connected to the lower surface of the silo pump 1. A second nozzle 12 is provided inside the discharge pipe 2. The second nozzle 12 is connected to the auxiliary connecting pipe 6. An inlet pipe 3 is fixedly connected to the silo pump 1. The inlet pipe 3 passes through the silo pump 1 and extends into the silo pump 1. A vent pipe 9 is provided inside the silo pump 1. The vent pipe 9 is fixedly connected to the inner wall of the silo pump 1. A first nozzle 10 is fixedly connected to the side surface of the vent pipe 9.
[0023] Specifically, the material enters the silo pump 1 through the feed pipe 3. During the descent, the guide plates 8 distributed in a ring on the inner wall of the silo pump 1 guide the material, preventing it from accumulating on the inner wall. Through the external control cabinet, after the air compressor 4 is started, high-pressure gas is supplied to the silo pump 1 through the main connecting pipe 5. A portion of the high-pressure gas is delivered to the nozzle 10 via the vent pipe 9. The fan-shaped nozzle 10 sprays gas into the material trough 13, causing the material in the trough 13 to be carried by the airflow, while simultaneously... The ultrasonic vibrator 11 operates, further preventing material from caking and clogging at the guide plate 8 and the trough 13 through vibration; another part of the high-pressure gas is transported through the auxiliary connecting pipe 6, and under the control of the one-way valve 7, the gas can only flow towards the discharge pipe 2, and finally sprays high-pressure gas into the discharge pipe 2 through the nozzle 2 12; under the combined action of the air pressure inside the silo pump 1 and the airflow sprayed by the nozzle 1 10 and the nozzle 2 12, the material smoothly enters the discharge pipe 2 from the bottom of the silo pump 1, and is transported through the discharge pipe 2 under the push of the airflow.
[0024] Working Principle: Material enters the silo pump 1 through the feed pipe 3. The external control cabinet is then turned on, and the air compressor 4 is started. During the material's descent within the silo pump 1, the annular guide plates 8 on the inner wall guide it, preventing material accumulation on the inner wall. The air compressor 4 delivers high-pressure gas into the silo pump 1 through the main connecting pipe 5. The gas flows in two streams. One stream of high-pressure gas is delivered to nozzle 10 via the vent pipe 9. The fan-shaped nozzle 10 sprays gas into the material trough 13, moving the material within. Simultaneously, the miniature ultrasonic vibrator 11 operates, further preventing material from clumping and clogging at the guide plates 8 and the material trough 13. The other stream of high-pressure gas is delivered through the auxiliary connecting pipe 6. Under the control of the one-way valve 7 (allowing gas to flow only towards the discharge pipe 2), it is finally sprayed into the discharge pipe 2 through nozzle 2. Under the combined action of the internal air pressure of the silo pump 1 and the airflow from nozzle 10 and nozzle 2, the material smoothly enters the discharge pipe 2 from the bottom of the silo pump 1 and is conveyed through the discharge pipe 2 by the airflow.
[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
